Abstract
The invention discloses a self-check system and method with linkage equipment taking no action. An alarm control chip of the system is internally provided with a self-check no-linkage control module, when a self-check signal is input to the control chip, the control chip drives an alarm unit to raise the alarm, an obstruction control chip issues a linkage driving signal to the linkage equipment, and the linkage equipment is kept taking no action. The system and method have the advantages that the linkage equipment takes no action during self check, and the linkage equipment is prevented from misoperation, such as closing a valve, opening a window and opening an air discharge fan abnormally, caused by self check; and whether an alarm is damaged can be actively checked via the self-check function of the alarm, the alarm with damage can be replaced or repaired timely, normal and effective work of the alarm is ensured, and hidden safety hazard is avoided.
Description
Technical field
The present invention relates to self-checking system and method that a kind of interlocking equipment is failure to actuate.
Background technology
Fuel Gas Leak Alarm is very important gas safe equipment, and it is last pipe protection of safe handling combustion gas.Fuel Gas Leak Alarm is by the low-concentration combustible gas in gas sensor detection surrounding environment, pass through sample circuit, by detectable signal analog quantity or digital transfer to control chip, when combustable gas concentration exceedes the value set in control chip, control chip controls send alerting signal or perform the actions such as closing gas valve door.The acquisition sensor of flammable gas alarm mainly contains oxide semiconductor-type, catalytic combustion-type, hot wire type gas sensors, also has a small amount of other types, as chemical cell class sensor.These sensors are all by the absorption to inflammable gas in surrounding environment, produce chemical reaction or electrochemical reaction, cause the change of the electric physical property of sensor at sensor surface.Fuel Gas Leak Alarm is widely used in the various fields such as city security protection, community, factory, company, school, family, villa, warehouse, resource, oil, chemical industry, gas transmission and distribution.
User, in the process using fuel gas alarm, alarm long because of alarm service time may to have an accident the reasons such as collision, water inlet, worries that alarm breaks down, and suspection gas leakage but alarm are not reported to the police.Although fuel gas alarm on the market has part to provide self-checking function, in process of self-test, alarm all can trigger the action of interlocking equipment while giving the alarm, and such as by-pass valve control is closed, and have impact on the normal use of combustion gas.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, self-checking system and method that in a kind of process of self-test, interlocking equipment is failure to actuate are provided, avoid the mistake caused because of self-inspection to close valve, open by mistake the misoperations such as window.
The object of the invention is to be achieved through the following technical solutions: the self-checking system that interlocking equipment is failure to actuate, comprise alarm and at least one interlocking equipment, described alarm is made up of self-inspection button and internal circuit, internal circuit comprises self-test signal and produces circuit, control chip and alarm unit, self-inspection button triggers self-test signal and produces circuit generation self-test signal, self-test signal produces circuit and is connected with the signal input part of control chip, the signal output part of control chip is connected with alarm unit, and the signal output part of control chip is also connected with each interlocking equipment;
Be provided with self-inspection not coordinated signals module in described control chip, when there being self-test signal input control chip, control chip drives alarm unit to give the alarm, and intercepts control chip simultaneously and issues linkage driving signal to interlocking equipment, keeps interlocking equipment to be failure to actuate.
Described interlocking equipment is gas meter valve, indoor window-opening mechanism or room ventilation mechanism.
Described alarm unit comprises hummer and alarm lamp.
The self-checking system that interlocking equipment is failure to actuate also comprises trouble light, and trouble light is connected with the signal output part of control chip.
The self-checking system that interlocking equipment is failure to actuate also comprises power light, and power light is connected with the signal output part of control chip.
The self-checking system that interlocking equipment is failure to actuate realizes the method for self-inspection, comprises the following steps:
S1: press self-inspection button, self-test signal produces circuit and produces self-test signal;
S2: control chip sends alerting signal to alarm unit after receiving this self-test signal:
(1) if alarm unit gives the alarm after pressing self-inspection button, simultaneous faults lamp is lighted and is once extinguished afterwards, power light Chang Liang, then normal, the alarm of warning function does not damage; While alarm unit gives the alarm, self-inspection not coordinated signals module has detected self-test signal input control chip, and self-inspection not coordinated signals module obstruct control chip issues linkage driving signal to interlocking equipment, and interlocking equipment is failure to actuate;
(2) if alarm unit is not reacted after pressing self-inspection button, then alarm damages.
Described alarm unit give the alarm specifically refer to: hummer sound a buzzer while alarm lamp flicker; Described alarm unit is not reacted and is specifically referred to: hummer does not pipe or alarm lamp does not work, or hummer does not pipe and alarm lamp does not work.
The invention has the beneficial effects as follows: in alarm control chip, be provided with self-inspection not coordinated signals module, during System self-test, control chip drives alarm unit to give the alarm, intercept control chip simultaneously and issue linkage driving signal to interlocking equipment, keep interlocking equipment to be failure to actuate, avoid the mistake caused because of self-inspection to close valve, open by mistake the misoperations such as window.Initiatively can check whether alarm damages by the self-checking function of alarm, if damaged, change in time or repair, ensure that alarm normally effectively works, stop potential safety hazard.
Accompanying drawing explanation
Fig. 1 is present system structural representation.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, the self-checking system that interlocking equipment is failure to actuate, comprise alarm and three kinds of interlocking equipment (gas meter valves, indoor window-opening mechanism and room ventilation mechanism), described alarm is made up of self-inspection button and internal circuit, internal circuit comprises self-test signal and produces circuit, control chip and alarm unit (alarm unit comprises hummer and alarm lamp), self-inspection button triggers self-test signal and produces circuit generation self-test signal, self-test signal produces circuit and is connected with the signal input part of control chip, the signal output part of control chip is connected with alarm unit, the signal output part of control chip is also connected with each interlocking equipment.
Self-inspection not coordinated signals module is provided with in described control chip, when there being self-test signal input control chip, control chip drives alarm unit to give the alarm, self-inspection not coordinated signals module is judged to be System self-test instead of normal gas leakage alarm, therefore self-inspection not coordinated signals module intercept control chip and issue linkage driving signal to interlocking equipment, keep interlocking equipment to be failure to actuate (gas meter valve be not related to hold one's breath, indoor window-opening mechanism is not opend the window, room ventilation mechanism do not open vent fan).
