Background
The fire-fighting work is directly related to the safety of people's lives and properties and the stability of society. In the automatic fire alarm system, after a fire occurs, related equipment needs to be started according to preset conditions, which is one of purposes and general requirements for arranging the automatic fire alarm system in a building.
In order to achieve the purpose, the currently adopted technical means is generally to arrange an embedded processor and a memory in the fire alarm controller, edit and store the preset linkage conditions and linkage results into the fire alarm controller, and the process is a trigger condition for setting linkage starting. After the fire-fighting linkage control system is set, the system is communicated with the alarm type equipment and the linkage type equipment in a certain communication period when the system works normally, and after fire alarm information in the system is received, the linkage type equipment in the system is controlled to be started through an instruction, so that the fire-fighting linkage control function is realized.

The current general operation mode of the process system is that alarm type equipment is set in a fire alarm controller in advance as a trigger condition for linkage starting, and the linkage type equipment is started after the trigger condition is met, but the process system has the following problems:
1 different building inner structure is complicated, can't regard as the trigger condition of fire control linkage with unified alarm device, the unable unified editing of fire control linkage control condition, if edit as the linkage condition to the trigger point of all fire alarm signal in the system, because the difference of the volume of the number of alarm points in the system, linkage control relation quantity corresponds the increase, the increase of linkage relation total number can cause the influence to information retrieval speed and the start-up speed after the conflagration takes place, personnel evacuation and automatic fire extinguishing after the conflagration takes place receive the influence.
2 in the automatic fire alarm system, the situation that the smoke fire detector and the temperature-sensitive fire detector of the alarm type equipment falsely detect the alarm and the situation that the manual fire button is manually and falsely operated inevitably occur, and the situations are regarded as false alarms. For false alarm information occurring in a building, if the false alarm information is used as a trigger condition of linkage control, false start of linkage equipment can be caused. Therefore, a common operation method is that two kinds of equipment and more than two simultaneous alarm signals are set in a building as starting conditions of linkage type equipment, different types of the equipment are superposed, and the workload of linkage relation editing operation in the early stage of the system is increased.
3 in the automatic fire alarm system, the installation positions of the alarm type equipment and the linkage type equipment need to edit and describe position information in advance according to the installation and monitoring areas, and the common editing and describing mode is to number according to buildings, divide areas, layer information and specifically number rooms. The classification is a classification mode for performing inclusion relation according to the size of a building region. Therefore, due to the deep classification hierarchy, the number of combinations for determining alarm position relationships increases, and at present, a mode of editing linkage relationships by using specific position description relationships is adopted, so that all combination relationships in a building need to be edited and set in advance in practical use.
