Residential parking lot management plan

Community parking lot management plan (1)

With the requirements of the new era of community management, smart communities and safe communities have gradually become the urgent voice of residents of the era. Smart parking systems and The combination of other series of security equipment provides an effective way to build smart communities and safe communities. Through scientific management methods, intelligent management of communities has become mainstream.

The following is the implementation plan of the community parking lot system

1. Main materials and tool requirements for project construction

1. Packaging of entrance and exit control machines, automatic gates, etc. It should be in good condition, the appearance of the material should not be damaged, and accessories, spare parts, and tools should be complete;

2. Engineering construction wiring standards, wire specifications and models, should comply with the parking lot engineering design requirements and the relevant regulations of standard parking lots ;

3. Bring complete relevant documents and information.

2. Engineering construction wiring technical requirements Parking lot system wiring must not only be safe and reliable, but also must make the wiring layout reasonable, neat and firmly installed. Cables should be installed horizontally or vertically in buildings, and should be protected with sleeves to make the cables secure and beautiful; 220V strong current and signal cables should be laid separately, not to be worn in the same pipe, and the distance should be greater than 50CM.

And all wiring must be sleeved, either PVC pipes or galvanized pipes, to prevent mice from chewing off the wiring and causing malfunctions.

If there is a breakpoint in the middle of the line, the breakpoint needs to be soldered with a soldering iron and insulated; the cables must be marked when wiring to facilitate future installation, debugging and maintenance.

Power cord entrance and exit gates and entrance control machines require 220V power supply, using three-core shielded wire (RVVP3*1.5). It is generally connected to a dedicated UPS dedicated line for power supply. In some cases, AC220V power supply can also be connected nearby. However, it should comply with relevant specifications and ensure that the ground wire in the AC220V socket in the system is truly grounded.

Networking cables

Parking lot networking methods can be divided into: 485 communication, TCP/IP communication, RS422 communication, etc. 485 networking lines must use shielded twisted pair RVVSP2*0.5, 485 bus The length can theoretically reach 1200 meters, but it is recommended not to exceed 1000 meters.

If it exceeds the limit, please use 485HUB or a repeater to improve the communication environment. In order to ensure the stability of communication, connect a resistor to the end of the communication line, or connect all the shielding layers. The end can be left floating or connected to the ground according to the situation. The 485 network must be a bus structure, and no full or partial star structure is allowed. The TCP/IP networking cable can be Category 5e unshielded twisted pair, and the distance from the controller to the switch or HUB should be less than 100 meters.

Equipment requirements:

Long-distance card reader signal line (card reader-controller): The card reader signal line uses a four-core shielded wire (RVVP4*0.5);

Button line (management room button-gate): The button line uses a four-core shielded wire (RVVP4*0.5);

Intercom line (intercom host-intercom extension): The intercom line uses a two-core shielded wire (RVVP2*0.5). The intercom line should be kept away from strong electricity and electromagnetic interference environments;

Display signal line (display-controller): The signal line uses two cores Shielded wire: RVVP2*0.5. In order to prevent the signal wire from being interfered, it must be laid separately from the power wire when laying;

Control wire (gate-control machine): Standard parking lot control wire uses four cores Shielded wire (RVVP4*0.5), simple parking lot (MAC board) uses two-core shielded wire (RVVP2*0.5), the specific situation depends on the type of parking lot;

Video cable (camera-control Room computer): The video cable adopts SYV75-5 video cable. Do not put it together with other strong power systems. A distance of 500mm should be kept.

3. Technical requirements for pipe laying (troughing) in engineering construction

There are two types of wire pipe (trough) wiring: open wire and hidden wire. The open wire pipe must be horizontal and vertical, neat and beautiful. Concealed pipes require short, smooth pipes and few elbows. The wire tubes (troughs) should be fixed at corners or every straight line distance exceeding 1.5 meters.

After inserting the wire into the vertical pipe opening that does not enter the box (box), the pipe opening should be sealed. In access control wiring, the diameter utilization rate of straight pipes should be 50~60, and the diameter utilization rate of curved pipes should be 40~50. If special circumstances arise during the construction process that require adjustments or modifications, they must be approved by the company leaders and customers before construction can begin.

When constructing wiring conduits (troughs), it is sometimes necessary to determine the slotting: slotting should be based on the following principles:

　①The principle of the shortest route;

② Do not destroy the original principle of strong electricity;

③Do not destroy the waterproof principle;

④Determine the slot width: Determine the number of PVC pipes according to the number of signal lines, and then determine the width of the slot ;

⑤ Determine the groove depth: If you choose a 16mm PVC pipe, the groove depth is 20-25mm; if you choose a 20mm PVC pipe, the groove depth is 25-30mm;

⑥Appearance requirements of wire ducts: horizontally and vertically, uniform in size;

⑦Measurement of wire ducts: cassettes and wiring box troughs are calculated independently, and all wire ducts are measured from the starting point of the slot to the end of the wire trough , if the width of the wire trough exceeds 80mm, it will be calculated as the length of the double wire trough;

⑧Sealing the trough: The wall and floor after sealing the trough shall not be higher than the plane where they are located, and shall be level with the original plane.

IV. Technical requirements for equipment installation

1. Entrance and exit control machines and automatic barrier gates

The distance between the control machine and the corresponding barrier gates shall not be less than three meters meters (the entrance and exit are the same);

The equipment should be perpendicular to the horizontal ground, with an inclination angle of no more than 1°;

The bottom of the box is in close contact with the ground, and the gap should be smoothed and sealed with cement;

p>

The box should not exceed the lane line, and should be at least 5 cm away from the edge of the lane;

The equipment must be firmly fixed without shaking, and the equipment should not be able to withstand an impact of 100kg/s. The shift is not loose;

The entrance control machine should be installed on the left side of the forward direction of the vehicle so that the driver can read the card from the left window of the vehicle.

2. Display screen

The display screen should be perpendicular to the horizontal ground, with an inclination angle of no more than 1°; it should be fixed at a position where the driver can easily see and reverse the vehicle.

3. Barrier control button

The barrier control button is installed in a place that is convenient for personnel to operate. The specific conditions will be operated according to the site.

5. Technical requirements for ground sensing coils

1. Coil material: standard Φ0.75mm high temperature resistant tinned wire;

2. Within 50 cm of the surrounding area There should not be a large amount of metal, such as manhole covers, rain gutter covers, etc.;

3. There should be no power supply lines exceeding 220V within 1 meter of the surrounding area;

4. Make multiple coils The distance between coils should be greater than 2 meters, otherwise they will interfere with each other;

5. For a standard 3-meter-wide road, the size of the ground sensing coil is 2 meters long and 1 meter wide, and the corners are 45°, 20 cm long cut angle;

6. The distance between the coil and the roadside is about 50 cm, and the coil is vertically stacked and wound 3-8 times, with a total length of 30-40m;

p>

7. Cutting parameters for buried wire trough: width 3-5mm, depth 40-50mm, the depth and width should be uniform, and try to avoid situations where it is deep and shallow, wide and narrow;

8. The coil should be in the same equilibrium position as the barrier gate or control machine;

9. The two wires leading out of the coil should be twisted, with a density of not less than 50 knots per meter, untwisted Output leads will cause interference. The output lead length should generally not exceed 5 meters. Since the sensitivity of the detection coil decreases as the lead length increases, the length of the lead cable should be as short as possible.

6. Technical requirements for safety islands

Safety islands are mainly used to place equipment and prevent vehicle collisions with equipment. If the equipment is installed on the roadside due to road width restrictions, the equipment installation foundation should be made on the roadside. Precautions for safety island construction:

1. If the size of the foundation for equipment installation should be more than 10 cm larger than the actual size of the equipment, to prevent expansion screws from bursting the foundation when fixing the equipment;

2. Safety island It should be about 10cm-15cm higher than the ground;

3. If the ground where the equipment is installed is a cement foundation, the foundation can be laid directly on the ground, but the laying place should be laid in a star shape every 25 cm. A steel bar (Φ20 or above), the steel bar should be no less than 5 cm deep into the ground and no less than 5 cm exposed;

4. If the ground where the equipment is installed is an asphalt foundation, the foundation can be laid directly on the ground , but the laying place should be laid with a steel bar (Φ20 or more) every 25 cm in a star shape. The steel bar should be no less than 20 cm deep into the ground and no less than 5 cm exposed.

7. System inspection and testing

Pre-installation inspection: Before installing the equipment, the type and quantity of the equipment must be checked against the installation contract in advance, and the equipment must be taken out from the warehouse after confirmation. After the equipment is taken out of the warehouse, all equipment needs to be tested one by one to check whether the equipment is normal and avoid trouble during installation.

Community parking lot management plan (2)

With the arrival of cold winter, severe weather will cause varying degrees of damage to various facilities and equipment in the community, bringing adverse consequences to residents’ lives. Influence. In order to ensure safety and prevent problems before they occur, property management companies should make early arrangements and preventive measures, formulate emergency plans in advance, and do a good job in the "three preventions" (antifreeze, antileakage, and antiskid) in winter to ensure the normal life and safety of community residents. travel.

1. Anti-freeze

With the arrival of winter, the first thing property management service companies must do is anti-freeze. Generally speaking, attention should be paid to three aspects: vacant houses, public facilities, equipment, and corridor insulation.

1. Antifreeze of vacant houses

(1) Antifreeze of vacant houses that property management service companies are responsible for taking care of. Some developers, out of trust in property management service companies and to reduce the trouble of caring for houses, hand over unsold houses or houses that have been sold but not checked in (especially commercial outlets) to property management service companies for care.

For this type of house, the following measures should be taken to avoid leakage and water leakage due to freezing of the water supply and drainage pipelines

Anti-freeze measures:

① Strengthen indoor cold protection and insulation. Check the exterior doors and windows of vacant houses (including balcony doors and windows). Missing glass should be replaced to ensure that the doors and windows are closed tightly. If necessary, the water supply and drainage pipelines should be insulated with rock wool and other insulation materials, and doors and windows that are not tightly closed should be sealed with straw mats and cotton curtains. For vacant commercial outlets without heating, the main water and sewer lines of the entire building are indoors. Once freezing damage occurs, all residents (users) of the entire building will be affected. Such accidents have occurred frequently over the years. Therefore, property management service companies cannot ignore cold protection and insulation, and should not be reluctant to invest in cold protection and insulation.

②Establish a vacancy inspection system. Designate a dedicated person to inspect vacant houses, generally once every three days, and at most once a week. During severe cold weather, key buildings (such as vacant commercial outlets with public facilities) should be inspected once a day, and any problems discovered should be reported and resolved in a timely manner.

③Establish an emergency mechanism. Develop a practical emergency plan before winter, set up an emergency maintenance team, and prepare emergency supplies and materials. Whether it is at night or on holidays, when receiving an emergency report, relevant personnel can rush to the scene in time to solve the problem as soon as possible. Really do not panic in emergencies, handle them properly, make timely repairs, and avoid losses.

(2) Frost protection of developers’ vacant houses. Developers are responsible for taking care of vacant houses that are not occupied due to sales or other reasons. Developers focus on whether vacant houses and facilities and equipment are lost, while property management service companies pay attention to whether these vacant houses will cause damage to the rights and interests of others. Therefore, property management service companies should communicate and negotiate with developers before winter to determine winter care and inspection methods for these vacant houses as well as emergency response plans. Clarify the person in charge and the contact method for both parties in handling emergencies of vacant houses, and establish a communication system between the two parties for daily care and inspection of vacant houses. It is necessary to ensure that the situation of vacant houses is clear, that both parties have clear emergency plans, that they communicate with each other in a timely manner, and that emergency response is implemented quickly.

(3) Frost protection of the owner’s vacant house. Regardless of the level of community, the phenomenon of vacant houses by owners is common. Most of the owners of these vacant houses lack understanding of the importance of antifreeze in winter and neglect to check the vacant houses in a timely manner. At the same time, they are unwilling to inform the community property management service office or neighboring owners of their relevant information, resulting in emergency situations. The owner of the vacant home could not be reached. Every winter, water leaks out of vacant houses (heating pipes or upper and lower water pipes freeze and crack, etc.) and the owner cannot be found. This causes great damage to neighboring owners. For such vacant houses, property management service companies should proactively find the owners of the vacant houses before winter, communicate and negotiate how to inspect the vacant houses in winter, and recommend that the owners take insulation measures for water and sewer lines, etc., and determine the risk of emergencies. Emergency solutions and exchange of contact information. At the same time, the owner should be informed of the responsibilities he should bear if an emergency occurs in the vacant house and causes damage to others. If there are no valuables in the vacant house, the property management service company can also store the owner's door keys (which need to be kept by a dedicated person) for use in emergencies.

2. Anti-freezing of public facilities and equipment

After entering winter, heat preservation and anti-freeze measures should be taken for all public facilities and equipment in the community. Water and sewer pipes, fire protection facilities, etc. are mostly located in corridors or in the basements of houses. Seasonal freeze damage is very easy to occur in the middle of winter: sewer pipes freeze, causing water blockage, and fire temperature sensing alarms freeze and crack, causing water leakage. This has happened in many communities. . Therefore, property management service companies must insulate these public facilities and equipment. Insulation methods can include perlite block enclosures or rubber tubes, rock wool, brown linen wrapping, etc. If necessary, a thermal air curtain facility can also be installed at the entrance to the basement (or underground parking lot). These insulation measures are a one-time investment that will benefit you for many years.

3. Sufficient attention should be paid to the insulation of corridors.

Corridor doors and windows should be closed tightly before winter, and any damaged glass should be repaired in time. Roof entrances and exits should also be tightly sealed and locked for protection if necessary. Corridor doors without door closers should be equipped with door bows to achieve automatic return closing of the corridor doors.

2. Leakage prevention

Leakage in the most common parts in winter is mainly at the location of downpipes on the roof and exterior walls.

1. Prevention and treatment of roof leakage

The main parts of roof leakage in winter are under the waterproof eaves of the parapet and the drainage outlet of centralized drainage. The reasons are: First, the waterproof eaves membrane is not firmly bonded and has raised gaps. When the snow on the roof melts and turns into water and exceeds the edge of the membrane, it leaks downward along the raised gaps; second, the drainage outlet is made of iron. The plates are welded, and the coils are pasted on the iron plates. In the cold winter, the expansion coefficients of the iron plates and the coils are different, and the coils are prone to warping. When the snow on the roof melts and turns into water, it leaks along the raised areas. In addition, the drainage outlet is narrow, which makes waterproofing construction difficult. The negligence of waterproofing construction workers is also one of the reasons for winter leakage here.

The main methods to prevent roof leakage in winter:

① Before winter, carefully check whether there are any warped gaps in the waterproof membrane under the parapet wall. If any gaps are found, apply waterproof oil Paste filling shall be firm and dense;

② Carefully check whether the iron plate of the drain outlet and the rolled material are tightly and in place. If it is not dense or not in place, immediately use a blowtorch to bake or re-paste the waterproofing Rolled material;

③ Once a roof leak occurs in winter, the accumulated snow and water (ice) on the roof must be quickly removed, and then the ice residue and water droplets in the leakage area must be carefully cleaned. If necessary, a blowtorch can be used to dry it. Then fill it with waterproof ointment.

2. Prevention and treatment of exterior wall downpipe leakage

Most roofs have organized drainage. In winter, the snow on the roof melts into water and flows from the roof drain outlet into the exterior wall downpipe. discharge. However, the downspouts on the exterior wall (especially the downspouts on the north exterior wall) are very cold and very long. When the snow water flows down the downspouts, it freezes on the inner wall of the downspouts, layer by layer, and gradually becomes ice and blocks it. The entire downspout then expanded and burst the downspout. This causes the snow water to leak out and flow along the exterior wall, and then freeze on the exterior wall when it is cold at night. The phenomenon of ice layer forming on exterior walls during cold winter can be seen everywhere, and this is the reason.

The main methods to prevent downspout leakage:

① During the melting of snow on the roof, pay attention to timely cleaning and drainage of accumulated water, and when it is approaching dark, use wooden sticks on the upper part of the downspout. Beat to break up the frozen layer adhered to the inner wall of the downspout to prevent the ice layer from accumulating thicker and blocking the entire downspout;

②When you find ice on the exterior wall, you must Clear the ice promptly. It can not only prevent the ice from falling and hurt people, but also reduce or prevent the mold and hair on the wall here when spring comes.

3. Anti-slip

In winter, due to the cold weather, the roads are very slippery with snow and ice, causing great inconvenience for people traveling. If you accidentally fall down, you may easily be injured and cause a safety accident. Therefore, you should inform the owner of some winter anti-slip knowledge and provide timely warm reminders.

1. Personnel anti-skid:

① Clear snow and ice on devices, roads, stairs, and passages in a timely manner.

② Set up anti-skid facilities on the main channels, such as anti-skid blankets, anti-skid mats, etc.

③In places where there is a risk of slipping, set up safety prompts.

④Hold on to the handrails when going up and down stairs.

⑤ When traveling in snowy weather in winter, you should wear non-slip shoes and walk on the pedestrian steps on the road.

⑥Don’t walk too fast on snowy days, keep your strides small, and don’t put your hands in your pockets, because swinging your upper arms back and forth can play a balancing role.

⑦ If you accidentally fall down on the road, try not to support the ground with your wrists, because this falling posture is most likely to cause arm fractures.

Once a fracture occurs after a fall, do not rub or move it to avoid aggravating the injury. Use scarves, wooden boards and other tools to fix the fracture site, ask others for help or call the police, and send the patient to the hospital for treatment as soon as possible.

2. Car anti-skid:

① Anti-skid chains, put a layer of anti-skid chains on the outer layer of the tire, just like putting anti-skid shoe covers on shoes as mentioned above. Relatively speaking, the price is relatively affordable.

②If the budget allows, you can change to snow tires. In order to ensure that your tires maintain good grip and control performance on winter roads and ensure the safety of your driving journey, it is beneficial to change to winter tires. Necessary.

3. Bicycle anti-skid:

Increasing the contact area between the wheels and the ground can prevent slipping. Owners are reminded to choose thicker tires. Do not carry too many or too heavy items on the vehicle body. During riding, remember not to brake suddenly, otherwise the wheels will slip and lose balance. When traveling in snow, it is better to ride slowly. Try to avoid sharp turns and keep your center of gravity perpendicular to the ground through the axis of the vehicle. The larger the turning radius within the allowable range of the road, the safer it is. Anti-skid bicycles increase the contact area between the wheels and the ground to prevent slipping, so it is best to choose thicker tires. Do not carry too many or too heavy items on the vehicle body. During riding, remember not to brake suddenly, otherwise the wheels will slip and lose balance. When traveling in snow, it is better to ride slowly. Try to avoid sharp turns and keep your center of gravity perpendicular to the ground through the axis of the vehicle. The larger the turning radius within the allowable range of the road, the safer it is.
