Abstract
The utility model discloses an intelligent inference based machine room early stage fire hazard class early warning system, comprising a suction type smog sensor, an A/D conversion chip, a temperature sensor, a central processing module MCU, a watchdog and a 3G module, wherein the suction type smog sensor is connected with the watchdog and the 3G module through the A/D conversion chip and the central processing module MCU; and the temperature sensor is connected with the watchdog and the 3G module through the central processing module MCU. Aimed at a machine room, which is a special protection place, the system gives an early warning for a fire hazard, and timely gives an early warning before a smoke and fire occur, thus preventing fire hazard accidents.
Description
Technical field
The utility model relates to a kind of machine room utmost point incipient fire grade early warning system, relates in particular to a kind of machine room utmost point incipient fire grade early warning system based on intelligent inference.
Background technology
The continuous propelling of information age, every profession and trade, government department grow with each passing day to the dependence program of infosystem, and the machine room carrier of these infosystems just, so the computer room safety problem is most important.Fire is one of key factor of harm computer room safety, and fire is carried out utmost point early warning, and fire is effectively controlled to preventing that event of fire from being very favorable in the early stage.
The evolution of fire comprises no visible smoke stage, visible smoke stage, burning (flame) stage and violent burning (high temperature) stage.No visible smoke, shared time in visible smoke stage are longer, and traditional passive type smoke transducer can't detect this information delicately, delayed alarm time greatly, miss best fire extinguishing opportunity.In addition because situation such as wrong report also possibly appear in environmental disturbances.Machine room is a special place, for guaranteeing the safe operation of machine room, fire is carried out extremely early stage early warning, makes pyrotechnics occur preceding early warning in time as yet, prevents that the heavy losses that fire failure is brought from being very important.
Summary of the invention
For solving above-mentioned middle problem and the defective that exists, the utility model provides a kind of machine room utmost point incipient fire grade early warning system based on intelligent inference.Said technical scheme is following:
A kind of machine room utmost point incipient fire grade early warning system based on intelligent inference comprises:
Air suction type smoke transducer, A/D conversion chip, temperature sensor, central processing module MCU, house dog and 3G module, said air suction type smoke transducer links to each other with the 3G module with said house dog with central processing module MCU through the A/D conversion chip; Said temperature sensor links to each other with the 3G module with said house dog through central processing module MCU.
The beneficial effect of the technical scheme that the utility model provides is:
Simple in structure, extensibility is strong, and fire is carried out utmost point early warning, pyrotechnics is occurred as yet before early warning in time, be in advance, can prevent the generation of fire failure.The utilization Fuzzy Inference is carried out classification to the fire that machine room takes place, and can take appropriate measures according to different ranks.Through the wired mode of RS485 early warning information is transmitted remote equipment room Monitoring Service platform, and send to the fire alarm related personnel, realize fire alarm remote monitoring, unmanned through wireless mode.
Description of drawings
Fig. 1 is based on the machine room utmost point incipient fire grade early warning system structural drawing of intelligent inference.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model embodiment is done to describe in detail further below:
As shown in Figure 1; Showed structure based on the machine room utmost point incipient fire grade early warning system of intelligent inference; The temperature sensor 2, central processing module MCU4,3G module 5 and the house dog 6 that comprise air suction type smoke transducer 1, A/D conversion chip 3, perception machine room environment temperature parameter, said air suction type smoke transducer links to each other with the 3G module with said house dog with central processing module MCU through the A/D conversion chip; Said temperature sensor links to each other with the 3G module with said house dog through central processing module MCU.
Above-mentioned air suction type smoke transducer is a kind of active smoke transducer; Be installed in the top of machine room internal monitoring chamber; Suck the machine room surrounding air and analyze through the inner asepwirator pump of detector, the output result be the smokescope signal, sends into central processing module after passing through the A/D conversion chip.
The said temperature sensor is a kind of two-wire system digital interface sensor, and this sensor directly is connected with central processing module, and the building environment temperature is monitored.
After above-mentioned central processing module carried out pre-service to smokescope signal, the temperature data that collects, the subordinate function through separately obtained estimating classification, obtains the fire alarm classification through setting up calculated with mathematical model.The process of fuzzy reasoning is: 1. set up evaluating collection U={u
1, u
2..., u
m, m=2, one of them is the smog parameter, another is temperature parameter; 2. set up opinion rating collection V={v
1, v
2..., v
n, n=5, the result is divided into 5 grades according to Fuzzy Calculation output.3. because the temperature variation of fire during glowing changes much smaller than smoke signal, therefore, blur weight sets A={ ω
1, ω
1... ω
k, k=2, wherein w
1=0.9, w
2=0.1.4. set up the fuzzy evaluation relational matrix:
r
IjRepresent that the i kind factor is cited as the possibility of j level, promptly the i kind factor is under the jurisdiction of the program of j grade standard.5. set up the mathematical model B=A ο R of fuzzy comprehensive evoluation, as fire size class early warning result, ο representes compose operation with the grade at maximum number place in the result calculated.
Above-mentioned watchdog chip is used for monitoring in real time the operation conditions of central processing module, can restart system automatically when abnormal conditions such as program fleet occurring when central processing module, improves the reliability of central processing module.
Above-mentioned 3G module adopts the EM560 module of supporting China Mobile network, and central processing module at first carries out initialization to module, and the early warning rating information sends to the 3G module then, and sends on related personnel's mobile phone with short message mode.Simultaneously, central processing module also is transferred to machine room Monitoring Service platform through the RS485 bus with the early warning rating information.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and is all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
