Distributed modular fire alarm control system

Abstract

The invention discloses a distributed modular fire alarm control system, which comprises a first-stage master control unit, a man-machine interaction unit, more than two second-stage master control units and intelligent terminal devices. The first-stage master control unit is used for receiving feedback information of the second-stage master control units and broadcasting the information to all second-stage units for information sharing, and is in data information interaction with the man-machine interaction unit; the man-machine interaction unit is used for realizing functions of printing, display, keyboard and acousto-optic instruction; the second-stage master control units are used for feeding back data information of the intelligent terminal devices to the first-stage master control unit and receiving broadcast information sent by the first-stage master control unit and obtained after feedback of the other second-stage master control units, and meanwhile, is in data interaction with the intelligent terminal devices; and a part of the intelligent terminal devices can be connected in series. The system is novel in design, stable and reliable in operation and convenient to use, greatly improves response speed of a controller, reduces response time and improves production efficiency effectively.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a decentralized modular fire alarm control system. Background technique [0002] As the core component of the fire protection system, the fire alarm controller is mainly used to complete the detection, alarm and fire extinguishing linkage functions of the entire fire protection system. It is the link between the detection system and the fire extinguishing system. Therefore, the performance of the fire alarm controller is directly related to the entire fire protection system. work performance. [0003] At present, the calculation, information processing, storage and other functions in the existing fire alarm controller are all completed by the control board, and the capacity of the controller is fixed. Since the operation, storage, and display in the control board occupy a large part of the RAM, the response speed of the control board is reduced and the response time is p...

AI Technical Summary

Problems solved by technology

Since the operation, storage, and display of the control board occupy a large part of the RAM, the response speed of the control board is reduced and the response time is prolonged, and the function boards can only work with the control board in "serial"

Therefore, the existing processing method greatly increases the "pressure" on the control board. To improve the response speed and response time of the control board, it is necessary to add multiple control boards, but this will greatly increase the cost.

[0004] In addition, during production assembly and testing, on the one hand, the existing fire alarm controllers have relatively high professional requirements for operators, which is not conducive to the improvement of production efficiency; It will lead to the failure of the entire controller to operate normally, and it is more difficult to find the fault
