What are the general alarm methods for computer room monitoring?

According to the requirements of users, this monitoring system realizes centralized monitoring of the power environment of the computer room, including the power system of the computer room (including main power distribution equipment, UPS power supply, power consumption monitoring), environmental system (water leakage, temperature and humidity of the computer room) and fire alarm. More importantly, the management measures of computer room should be integrated, and the personnel on duty should be prompted to operate various events through network alarm and SMS alarm. Realized the unified monitoring of the equipment in the computer room, very intelligent real-time network alarm, SMS alarm, real-time event recording; Reduce the burden of the maintenance personnel in the computer room, effectively improve the reliability of the system, clean up the relationship between events, and realize the reliable and scientific management of the computer room.

First, the alarm mode

1, the network monitoring center gives an alarm.

The system has built-in fixed IP address, logs in to the server through GPRS wireless communication (without using wired network), and uploads alarm information, dynamic parameters and scene photos to the network monitoring center of the client.

2, SMS alarm

Through SMS authorization or computer settings, you can set up five alarm calls. When the temperature, humidity, UPS power and other analog quantities exceed the predetermined limit, it will immediately send alarm information to the alarm phone; When there is power failure, incoming call, smoke and water leakage in the computer room, the alarm system will immediately send alarm information to the alarm phone.

3, MMS photos

You can add a 30W pixel CDD camera through the serial port. When the alarm occurs, the scene image can be sent to the monitoring center, mobile phone and e-mail box through MMS, which is convenient to determine the alarm situation and obtain evidence, and completely solves the trouble of false alarm. The monitoring center can take the initiative to apply for taking photos and archive them.

4, telephone dialing reminder

It can be set by SMS or computer: after the switch sensor of the system is triggered, it can not only send SMS to the alarm phone, but also dial the alarm phone, and can monitor the live voice after being connected.

5, the scene sound and light alarm

By setting the software, you can set the alarm clock to send short messages (dial) and activate the alarm clock (alarm). The alarm interface is a standard active control output, and users can connect other alarm speakers according to their own needs.

Second, the system standard configuration (hardware)

1, host (built-in multiple sensors: one-way temperature, humidity, power failure, heavy power, 380V three-phase four-wire phase-missing sensor and three-way UPS battery charge detection sensor (including two 500V and one 5000v); Built-in GSM/GPRS communication module; Built-in wireless detector receiving module; Built-in multi-channel I/O interface)

230 watt pixel CDD HD camera

3.GSM/GPRS sucker antenna (line length 5 meters)

4. Two sets of temperature and humidity sensors (line length10m)

5. Cable audible and visual alarm

6. Operation guide

7.RS232 data line

8. CD-ROM (including system setup software, network monitoring center software, Android mobile phone monitoring center software, electronic operation manual and system simple operation guide)

Third, the basic function

1, temperature alarm

The temperature sensor is a digital temperature sensor produced by Dallas Semiconductor Company, which is used to test the ambient temperature. The detection range is -55 ~ 125℃, the accuracy is 0.5℃, and the display step is 0. 125℃.

2. Humidity alarm

Test the ambient humidity, the humidity range is 0 ~ 100% RH (condensable), and the humidity detection accuracy is 4%RH (conditions: 25C, 60%RH, Vin=5.0V, output voltage range: 1.68 ~ 1.92V).

3, power failure alarm

The AC /DC isolation technology is adopted to monitor the power supply of commercial power in real time through the AC power supply provided by the system. When there is power failure, the mains power failure detection module sends a power failure signal to the alarm host, and sends an alarm short message to the set mobile phone through the short message alarm module.

4. Complex alarm

After the commercial power is restored, the commercial power recovery detection module sends a power-off signal to the alarm host, and sends an alarm short message to the set mobile phone through the short message alarm module.

5. UPS battery charge alarm

Directly connected to the positive and negative poles of the battery pack inside UPS, the battery pack voltage can be detected online in real time. The maximum detection voltage is 500V (two circuits) and 5000V (one circuit), and the upper and lower limits of battery voltage can be set, and short message alarm can be given when the battery exceeds the limit. Three sets of UPS battery voltages can be detected at the same time.

6, power electricity (three-phase four-wire) lack of phase alarm

Real-time detection of three-phase four-wire system by photoelectric coupling isolation sampling technology. When any phase line in the three-phase alternating current is powered off, it will immediately send an alarm message to the preset mobile phone. It can also be used for real-time online detection of three-phase 1 10V or single-phase 220V mains.

7, wired switch alarm input

Four passive switch input interfaces are reserved, one of which is a wired panic button 24-hour area; At the same time, the switch input interfaces provided by two routing systems are retained, and there is also a 24-hour compulsory defense zone. These six kinds of switch alarm information can be set by users through SMS or computer software.

8. Wireless alarm reception

The system integrates wireless alarm receiving module, and adopts 3 15MHz fixed coding mode, which can receive 12 wireless switch signals such as wireless smoke detector and wireless water immersion detector, and then send them to the alarm phone by SMS from the host.
