The working principle of the input and output modules in fire alarm

The working principle of the fire protection module

What is the specific working principle of the input and output modules in the fire alarm system, that is, how the input and output modules actually work. Here we will introduce the working principle of the input and output module in detail. In fact, a microprocessor is embedded in the input and output module. Through the microprocessor, communication with the fire alarm controller, power bus power-down detection, output control, input signal logic state judgment, input and output line fault detection, and status indicator lights are realized. control. After receiving the start command from the fire alarm controller, the module closes the output relay and lights up the indicator light. After the input and output module receives the answer signal from the device, it transmits the information to the fire alarm controller. It is mainly used to connect fire linkage equipment that needs to be controlled by a fire alarm controller, such as alarm bells, sound and light alarms, fire shutter doors, water pumps, smoke exhaust fans, elevators, broadcast switching, etc.

We use 4 devices to explain the working principle of the input and output module in detail: smoke detector, controller, input and output module, and fire pump. When the smoke detector detects a fire, it transmits information to the controller. The controller sends a signal to the fire pump through the output terminal of the input and output module to start the fire pump. After the fire pump starts, it transmits the startup information through the input terminal of the input and output module. to the controller. This is how the actual input and output modules in the fire alarm system work.

Python supports multi-threading and is a native thread. It is mainly implemented through the two modules thread and threading. Thread is a relatively low-level module, and threading provides some packaging for thread, which can be used more conveniently. What needs to be mentioned here is that python's support for threads is not perfect enough and cannot utilize multiple CPUs. However, improvements to this point have been considered in the next version of python. Let's wait and see.

The threading module mainly objectifies some thread operations and creates a class called Thread. Generally speaking, there are two modes for using threads. One is to create a function to be executed by the thread, pass this function into the Thread object, and let it be executed; the other is to inherit directly from Thread and create a new class. Put the code executed by the thread into this new class. Let’s take a look at both approaches. The working principle of the fire protection module (1)

The guiding ideology of the county’s fire protection publicity work is: to promote the rapid and easy development of fire protection work under the new situation, to prevent major fire accidents as the goal, and to serve the talented people With the county's economic and social development as the main line, we will further strengthen the leadership of fire protection publicity, strive to improve the national fire safety awareness and legal concepts, provide strong public opinion support for deepening the construction of social fire safety "firewall" project, and provide a smooth start for the "Twelfth Five-Year Plan" and The 90th anniversary of the founding of the Party and the successful convening of the "Seven Cities Conference" created a good fire protection publicity environment.

All towns, towns, and departments should make full use of various resources and media to carry out public welfare fire protection publicity, and set up large-scale light box advertisements and LED video fire protection announcements in prominent locations such as county centers, cultural squares, highway entrances, and scenic spots. There should be no less than 4 public service advertising billboards, and according to the needs of phased work, more billboards should be added in a timely manner, and the publicity content should be updated in a timely manner. Village committees, communities, and residential areas should make full use of cultural stations, activity rooms, squares, publicity boards, cultural showcases, etc. to establish 2-4 relatively fixed publicity positions. Fire science education bases can be established in places where conditions permit.

2. Give full play to the regulatory role of the industry system and establish and improve the system functions of socialized fire protection publicity

(5) Deepen fire safety demonstration and creation activities. The education department must continue to do a good job in the creation of "Fire Safety Education Demonstration School", strive to create a municipal-level "model school", strive for a provincial-level "model school", and actively create a national-level "model school". Targetedly carry out "fire safety education courseware lesson plan evaluation activities, fire protection art performances, emergency evacuation drills, fire fun sports meetings, fire volunteer visits and fire cartoon competitions" to give full play to the radiation effect of model schools and improve students' , family fire safety awareness. On this basis, we should carry out fire safety training for principals of primary and secondary schools, carry out selection activities such as "Little Fire Guards", "Fire Protection Safety Ambassador", "Eagle Action Fire Fighting Badge", etc., and conduct educational supervision and work assessment.

Village committees and communities should carry out safety creation activities such as safe streets, safe communities, safe villages and towns, and establish at least one fire safety demonstration site. The working principle of the fire protection module (Part 2)
