Description

Point-type combustible gas detector
Technical field
The utility model relates to a kind of combustible gas probe, particularly relates to the point-type combustible gas detector that a kind of reliability is high, the life-span is long
Background technology
Flammable gas alarm detects combustible gas leakage and sends in time that the prevention such as sound and light alarm is caught fire, the safety feature of injures and deaths as a kind of, just more and more causes people's attention, and it just plays an important role in commercial production with in living at home.The producer of domestic production combustible gas probe is more at present. and the product emphasis of each producer is different.There is short, the shortcoming such as rate of false alarm is high, rate of failing to report is high and intelligent level is low in serviceable life in combustible gas probe.Present combustible gas detecting product can only be realized the monitoring of single household, can not realize networking monitoring.Existing combustible gas detecting product only can be realized the monitoring to gas leakage mostly, can not realize the monitoring to the product self performance.
The utility model content
The purpose of this utility model is a kind of simple in structure, long service life to be provided in order addressing the above problem, the warning accuracy is high and realizes the point-type combustible gas detector of remote monitoring.
The utility model is achieved through the following technical solutions:
A kind of point-type combustible gas detector, comprise end box, loam cake, circuit board and sensor module, be provided with single-chip microcomputer on the described circuit board, sensor control circuit, data acquisition circuit, A/D converter, alarm, storer and communication interface, the signal input part of described sensor module is connected with the signal output part of described sensor control circuit, the signal input part of described sensor control circuit is connected with the control signal output terminal of described single-chip microcomputer, described sensor module is connected with the signal input part of described data acquisition circuit, the output terminal of described data acquisition circuit is connected with the signal input part of described A/D converter, the signal output part of described A/D converter is connected with the signal input part of described single-chip microcomputer, the FPDP of described single-chip microcomputer respectively with the FPDP of described storer, the FPDP of alarm be connected communication interface and connect.
Further, described sensor module comprises combustable gas concentration sensor and smoke transducer.
Further, described sensor module is installed on the sidewall of box of the described end.
Further, the bottom of described end box is provided with mounting base.
The beneficial effects of the utility model are:
The utility model can carry out continuous monitoring with interior inflammable gas, smog to lower explosive limit scope in the industrial environment, and change gas concentration and system information into electric signal, identify, show and process for adaptive AEC2300 series A-BUS four bus communication controllers by bus communication modes real-time Transmission processed.By adopting single-chip microcomputer technology and the highly sensitive anti-toxic type gas sensor of import brand, the variation that can automatically conform, automatically revise the transducer sensitivity decay, keep stable warning sensitivity, but also the ability that possesses the identification sensor fault and provide high concentrations of gas to transfinite protection; When sensor may lose function owing to wearing out, detector can also be identified and report to the police automatically, has effectively avoided failing to report.
Description of drawings
Fig. 1 is the structural representation of the utility model point-type combustible gas detector;
Fig. 2 is the circuit block diagram of the utility model point-type combustible gas detector.
Among the figure: 1-loam cake, box at the bottom of the 2-, 3-sensor module, 4-mounting base.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments:
As depicted in figs. 1 and 2, a kind of point-type combustible gas detector of the utility model, comprise end box 2, loam cake 1, circuit board and sensor module 3, be provided with single-chip microcomputer on the described circuit board, sensor control circuit, data acquisition circuit, A/D converter, alarm, storer and communication interface, the signal input part of described sensor module is connected with the signal output part of described sensor control circuit, the signal input part of described sensor control circuit is connected with the control signal output terminal of described single-chip microcomputer, described sensor module is connected with the signal input part of described data acquisition circuit, the output terminal of described data acquisition circuit is connected with the signal input part of described A/D converter, the signal output part of described A/D converter is connected with the signal input part of described single-chip microcomputer, the FPDP of described single-chip microcomputer respectively with the FPDP of described storer, the FPDP of alarm be connected communication interface and connect.
Sensor module 3 comprises combustable gas concentration sensor and smoke transducer.Sensor module 3 is installed on the sidewall of end box 2.The bottom of end box 2 is provided with mounting base 4.
Principle of work of the present utility model: sensor module 3 sends to data acquisition circuit with the detection signal that detects, data acquisition circuit is converted into digital signal through A/D converter with simulating signal with signal after treatment, data-signal transfers to single-chip microcomputer, single-chip microcomputer compares the signal of collection and gas concentration and the smokescope of setting, when the signal that gathers surpasses setting value, single-chip microcomputer sends alerting signal to alarm, and alarm gives the alarm.The transducer sensitivity decay is revised in the variation that sensor is conformed automatically by sensor control circuit is set automatically, keeps stable sensitivity.
