The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalence or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
See also shown in Figure 1: extinguish and anti-explosion of the present invention system comprises supply module, system fault diagnosis module, fire alarm testing circuit, instant fire extinguishment treatment circuit, fire-suppression bottle drive circuit and bus driving circuits.Be installed in the fire signal that the on-the-spot purplish red outer composite flame detecting device of monitoring transmits and handle, send into microprocessor analysis, processing, determine the signal driving fire-suppression bottle that output is corresponding according to position of detector and numbering through the fire alarm testing circuit.This system controller also needs state, the state of detector, core devices work, the instant fire extinguishment on off state of fire-suppression bottle are detected, and detector, fire-suppression bottle, control circuit, Primary Component are carried out fault diagnosis and export relevant information.The information of whole extinguish and anti-explosion device is uploaded by bus.
Each flame detector when system, when controller, emergency switch correctly were connected energising work with fire-suppression bottle, whole extinguish and anti-explosion system promptly dropped in the automatic monitoring and the datonation-inhibition course of work of self-extinguishing to fire.
The controller circuitry circuit theory diagrams are divided into power supply by function, microprocessor, and fire alarm detects handles communication, circuit such as fire-suppression bottle state-detection and driving.
Controller input fire alarm as shown in Figure 2 detects treatment circuit, circuit in this section, select LM139 that the input signal of detector is compared, after P621-4 light lotus root isolation processing, enter microprocessor, analyze, this part energy can be finished the detection of the signals such as fire alarm, detector broken string, detector output and 15V power supply short circuit, detector output and ground short circuit of purplish red outer complex detector.When detector broken string and power supply short circuit, the signal voltage that enters the LM139 comparator is 15V, when detector and ground short circuit, signal voltage 0V, detector and collection driver card be signal voltage 7.5V just often, signal voltage 3.2V when the detector dryness-fire is alert, in order accurately to distinguish the state of detector, consider the fluctuation and the jamproof needs of voltage simultaneously, when carrying out circuit design, selected 11.5V, 8.2V, 5V, these several magnitudes of voltage of 1.5V, the base value judged of device as a comparison, fire alarm to detector is limited between the 1.5V-5V, and only in this close limit, the datonation-inhibition system of self-extinguishing just can be treated as fire alarm to signal, signal outside this scope will be suppressed, and guarantee that like this fire alarm of gathering is true, effectively.
Controller fire-suppression bottle state detection circuit as shown in Figure 3, the detection of fire-suppression bottle empty bottle signal adopt high-speed photoelectric coupler to detect, and its status signal enters cpu, adopt interrupt mode in time to respond its state variation.
The electric detonator state adopts multiway analog switch (CD4051) control, regularly injects little current signal timesharing and detects, and guarantees that misoperation does not take place electric detonator.Normal condition, per minute detects the once state and the CPU ruuning situation of each electric detonator, when the situation generation of the fire extinguishing of driving is arranged, detects the state of electric detonator constantly.
According to controller fire-suppression bottle drive circuit shown in Figure 4, after system detected fire alarm, microprocessor was carried out the fire extinguishing control task on request, at electric detonator detonator signal output port output HIGH voltage, drive the high speed photo coupling conducting, bottle power supply circuits and fire-suppression bottle drive circuit are opened in control respectively, open a bottle power supply circuits conducting, for the fire-suppression bottle drive circuit provides power supply, fire-suppression bottle drives the triode conducting, voltage directly is added in the electric detonator two ends, produces the electric current greater than 3 A, ignites electric detonator and puts out a fire.
According to extinguish and anti-explosion system emergency switch circuit theory diagrams shown in Figure 5, when pushing manual fire extinguishing button (SB1, SB2), transistor base voltage is lower than emitter voltage, and fire-suppression bottle drives the triode conducting, realizes outage fire extinguishing control.For the assurance system can reliably start fire-suppression bottle in 2 hours again, controller is by the big capacitance energy storage of 3 1000u.By test of many times, the 0.5A protective tube that all can reliably fuse after cutting off the power supply 3～4 hours starts simulation fire-suppression bottle (voltage is higher than 20V and could starts).
According to system control program FB(flow block) shown in Figure 6, when start powered on, software systems brought into operation, and at first carry out initialize routine, to the IO port, timer module, communication module is configured, carry out self-check program then, check light, whether output devices such as buzzer are intact.After self check finished, system entered an Infinite Cyclic course of work,
In this process, do not stop to monitor fire alarm and handle communication function, self-test signal input, fire-suppression bottle state and light indication.In the software systems, the emergency switch signal takies the 0 tunnel external interrupt, and the fire alarm of detector takies all the other external interrupt.
When the emergency switch signal interruption was effective, software systems were ended the execution of other subprograms, turned to the handling procedure of carrying out emergency switch, and detect the state of fire-suppression bottle this moment, according to the numbering and the corresponding fire-suppression bottle of sequence starting of alarm detector.Timing begins after pressing emergency switch, does not return if monitor corresponding empty bottle signal in the 60ms, thinks that then the fire-suppression bottle that has just started breaks down, and system will start the standby fire-suppression bottle of this fire-suppression bottle.Software is provided with emergency switch and postpone handles, and presses the emergency switch 5s behind the fire-suppression bottle that detonates, and just allows emergency switch effective once more, plays the effect of saving fire-suppression bottle.
After interrupt mode affirmation fire alarm information, system will close the residing interruption of this alarm detector, report to the police no longer valid with interrupt mode, change the level value of this road interrupt pin of monitoring into, 5s clock after detonating first, if the level signal of fire alarm is kept always, then system thinks that fire condition continues, system will continue the fire-suppression bottle program of detonating, and the detection that begins behind the next 5s is handled.
If after detecting fire alarm first, system detects this road fire detector fire alarm in the middle of periodic duty level value returns to the state of no fire alarm, and then system thinks that fire is extinguished, and initial shape will recover in system.
Preferred example described above only is that the present invention is set forth and illustrates, but is not limited to disclosed concrete any form, and it is possible carrying out many modifications and variations.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
