Abstract

The utility model relates to a novel fire prevention control system which comprises a switch trigger circuit and a single chip microcomputer control circuit. Output signals of the switch trigger circuit are transmitted to a zigbee wireless module circuit and a water spraying driving circuit through the single chip microcomputer control circuit, and output signals of the zigbee wireless module circuit are transmitted to a data processing center. An inflammable and explosive area is arranged, copper wires are wound in an plastic insulator to enclose an area where monitoring is needed, and when fire happens, the copper wires are burnt out, a spraying system is linked to spray water to extinguish fire after judgment of the single chip microcomputer control circuit, and simultaneously networking is carried out through a zigbee wireless module, alarming signals are sent to the data processing center fast, and accordingly staff are guided to go for failure processing.

Description

A kind of novel strick precaution fire is controlled system

Technical field

The utility model relates to a kind of fire control circuit, particularly be a kind of novel strick precaution fire control system.

Background technology

It all is because of little fire changes big fire that all fire have an accident, thus should when burning things which may cause a fire disaster takes place timely flame, simultaneously guarded region can be set, improve the reliability of fire extinguishing.

The utility model content

The purpose of the utility model is to provide a kind of novel strick precaution fire to control system.

The utility model solves the technical scheme that its technical problem adopted: a kind of novel strick precaution fire is controlled system; Comprise switch triggering circuit and single chip machine controlling circuit; The output signal of said switch triggering circuit is sent to ZigBee wireless module circuit and water spray drive circuit through single chip machine controlling circuit control, and the output signal of said ZigBee wireless module circuit sends to data processing centre.

Preferably, said single chip machine controlling circuit also with the watchdog circuit bidirectional data communication.

Preferably, said switch triggering circuit is connected to transistor Q1 at the output of the copper wire cable FA of surveillance area through resistance R 2 by circle and constitutes, and the base stage of said transistor Q1 is vacant state.

Preferably, said ZigBee wireless module circuit adopts ZM2410 wireless communication module IC3.

Through adopting above-mentioned technical scheme, the beneficial effect of the utility model is: the utility model adopts sets inflammable and explosive zone, lives to need the monitoring position zone with putting on the copper wire coil in the plastic insulation; When fire takes place, blow copper wire, after judging through single chip machine controlling circuit; Interlock spray system sprinkling fire through the ZigBee wireless module, carries out networking simultaneously; Send alarm signal to data processing centre rapidly, thereby instruct personnel to go to handling failure.

Description of drawings

Fig. 1 is the frame assumption diagram of the utility model;

Fig. 2 is the circuit theory diagrams of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further to specify.

Like Fig. 1, shown in Figure 2; A kind of novel strick precaution fire of the utility model is controlled system; Comprise switch triggering circuit 1 and single chip machine controlling circuit 2; The output signal of said switch triggering circuit 1 is sent to ZigBee wireless module circuit 21 and water spray drive circuit 22 through single chip machine controlling circuit 2 control, and the output signal of said ZigBee wireless module circuit 21 sends to data processing centre 211, said single chip machine controlling circuit 2 also with watchdog circuit 3 bidirectional data communications.

Form the power supply municipal electric conversion circuit by resistance R 1, capacitor C 1, Zener diode DW, bridge rectifier D1-D4 etc.; The urban network electricity source is after resistance R 1, capacitor C 1 step-down; After bridge rectifier D1-D4 rectification; Through capacitor C 2 filtering, Zener diode DW voltage stabilizing provides power supply for this device again.

Said switch triggering circuit 1 is connected to transistor Q1 at the output of the copper wire cable FA of surveillance area through resistance R 2 by circle and constitutes, and when fire took place, horse back can blow copper wire cable FA; The base stage of transistor Q1 is vacant state, and emitter stage is high level output, and the 27th pin I/O end that this signal is input to single-chip microcomputer IC1 also is high level; After single-chip microcomputer IC1 judges, divide two-way to send control signal, first via output; Form ZigBee wireless module circuit 21 by the 6th, 7 ends of ZM2410 wireless communication module IC3 and the 10th, 11 ends of single-chip microcomputer IC1, ZM2410 wireless communication module IC3 is the embedded serial ports transparent transmission of the Zigbee of built-in 2.4GHZ (some multiple spot and point-to-multipoint) communications protocol, supports aerial upgrade firmware or configuration far module information; Receiving sensitivity up to output of the power of 7dBm and-100dBm; Can satisfy telecommunication, send the AT instruction by single-chip microcomputer IC1 ZM2410 wireless communication module IC3 is realized wireless data transceiving, switch pin with the RS-485 direction; Send current fault message to data center; This module is the honeycomb fashion networking, reaches distance, low cost and other advantages; The second tunnel output, the 2nd pin output high level signal by single-chip microcomputer IC1 through resistance R 4 current limlitings, makes transistor Q2 conducting, the relay J adhesive, magnetic valve MQ gets electric, and spray system begins water spray.

An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
