Embedded single loop linkage fire-fighting system for fire disasters

Abstract

The invention discloses an embedded single loop linkage fire-fighting system for fire disasters, comprising a control main unit and a terminal node, wherein the terminal node is arranged in a detection filed, and used for the detection and extinguishment of the detection field, the control main unit is arranged in a management centre, the control main unit and the terminal node are connected through two buses, a central control unit in the control main unit is in serial communication with other functional modules through I2C buses. In the system, an embedded controller is used, the design of the hardware is simplified, the functions of the hardware are enhanced, the use is more convenient, the extension function and upgrade capacity are improved, the intellectualization degree of the system is higher, the hardware cost is greatly lowered, and the stability and reliability of the whole system are improved.

Description

technical field [0001] The invention relates to the field of electronic fire protection, in particular to an embedded single-circuit fire linkage fire protection system. Background technique [0002] The existing fire alarm system is combined into different loops according to the number of alarm nodes, and then multiple loops are connected to the main control equipment to form a complete alarm linkage system. Generally, each circuit has less than 100 alarm units, and linkage equipment has less than 100 input and output linkage control units. Most fire protection systems support multiple loop connections. In this way, the number of alarms and linkage units in the overall system is relatively large, and the equipment cost is also high. This system is suitable for buildings and office buildings with concentrated node distribution. Its working principle is: the temperature and smoke detection and alarm units on each circuit detect and alarm fires according to the site conditio...

AI Technical Summary

Problems solved by technology

There are also fire alarm controllers with less alarm and linkage units on the market, but the networking capability is poor, the expansion capability is not strong, it is not suitable for unified management, and the level of intelligence is limited

[0004] If the number of alarm and linkage units is scattered, the materials and costs required for installation will increase greatly

The use of a master control device with a large number of processing units and a strong processing capacity cannot reduce costs, nor can it give full play to the technical advantages of the master control device

Existing fire alarm controllers with fewer alarm and linkage units generally use single-chip microcomputers as the control core, which reduces the cost, but the performance is also greatly reduced, mainly reflected in the limited networking capabilities and expansion capabilities, and can only be suitable for a certain number of areas. It is also not conducive to actual use, the product is low-end, and the performance is greatly reduced
