Description
Technical field
The utility model relates to a kind of supervising device, specifically a kind of household fuel gas supervising device.
Background technology
Along with the raising of people's living standard, the use of piped gas is more and more general, makes people's life become more convenient, if but forget and close jet after using, just may soft coal gas leakage, as do not found in time, likely there is very large accident.Mostly there is the problem that gas concentration signal is inaccurate, accuracy of detection is not high that gathers in current household fuel gas supervising device on the market; And in the time of the data acquisition to sensor, for the processor that A/D translation interface is not set, if gather two-way or simulating signal more than two-way, just need to be by external A/D conversion chip; But how to allow processor can gather the data after A/D conversion, can send again analog channel and select signal, also concrete, not effective circuit is realized.
In the time that gas concentration is too high, existing household fuel gas supervising device only sends warning in addition, and exhaust apparatus does not spread out the coal gas of leakage, if run into the situation that people sleep soundly or stay out, still has larger threat.
Summary of the invention
The problem existing for prior art, the invention provides that one can accurately detect in real time and the household fuel gas supervising device of the index such as display environment temperature, methane (being coal gas) concentration, in the time that each index meets or exceeds warning value, can send accurately alerting signal and automatically take various corresponding measures to avoid accident to occur.
For solveing the technical problem, the technical solution adopted in the utility model is: a kind of household fuel gas supervising device, the detection module, display and the alarm that comprise processor, be connected with processor; Described detection module is made up of temperature sensor, methane transducer and multi-channel a/d converter, and temperature sensor is connected with the different input ends of multi-channel a/d converter respectively with methane transducer, and the output terminal of multi-channel a/d converter is connected with processor; Also comprise that analog channel that a latch processor sends selects the latch of signal, latch input end is connected with processor, and output terminal is connected with the analog channel selecting side of multi-channel a/d converter.
In the utility model preferred version, also comprise an exhaust apparatus 1 being made up of relay 1 and window opener, the relay 1 in described exhaust apparatus 1 is connected with processor.
In the utility model preferred version, also comprise an exhaust apparatus 2 being made up of relay 2 and scavenger fan, the relay 2 in described exhaust apparatus 2 is connected with processor.
In the utility model preferred version, described processor is STC89C52 single-chip microcomputer, and multi-channel a/d converter is ADC0809, and latch is 74LS373 latch, and display is LCD liquid crystal display.
The beneficial effects of the utility model:
The utility model is by detection module and display, can accurately detect in real time and the information of display environment temperature, methane concentration, and in the time that methane concentration exceeds standard, the utility model can automatic alarm and started exhaust apparatus and reduce leakage gas concentration.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises single-chip microcomputer STC89C52, is connected with single-chip microcomputer STC89C52 detection module, LCD liquid crystal display and alarm; Described detection module is made up of temperature sensor DS18B20, methane transducer MQ-5 and multi-channel a/d converter ADC0809, temperature sensor DS18B20 is connected with input end IN0, the IN1 of multi-channel a/d converter ADC0809 respectively with methane transducer MQ-5, and the output terminal D0-D7 of multi-channel a/d converter ADC0809 is connected by the P00-P07 mouth of connector JP3 and single-chip microcomputer STC89C52; Also comprise the latch 74LS373 of a latch analog channel selection signal, latch 74LS373 input end DO-D7 is connected with the P00-P07 mouth of single-chip microcomputer STC89C52 by connector JP3, and output terminal O0-O2 is connected with analog channel selecting side A, B, the C of multi-channel a/d converter ADC0809.In the present embodiment, also comprise exhaust apparatus 1 and exhaust apparatus 2, described exhaust apparatus 1 is made up of relay 1 and window opener, and relay 1 is connected with single-chip microcomputer STC89C52; Exhaust apparatus 2 is made up of relay 2 and scavenger fan, and relay 2 is connected with single-chip microcomputer STC89C52.
Principle of work of the present utility model: temperature sensor DS18B20 and methane transducer MQ-5 detect respectively in real time to environment temperature and gas concentration, the data transmission recording is to the IN0 of ADC0809, IN1 end, now single-chip microcomputer STC89C52 sends the analog channel selection signal of 8 to latch 74LS373, this signal transfers to the analog channel selecting side of multi-channel a/d converter ADC0809 after the decoding latch of latch 74LS373, multi-channel a/d converter ADC0809 according to select analog channel to temperature and methane concentration carry out A/D conversion and transmission respectively, the temperature and the gas concentration that transfer to single-chip microcomputer STC89C52 show in LCD liquid crystal display.When the gas concentration detecting is while reaching certain value, single-chip microcomputer STC89C52 controls alarm equipment alarm, thereby and window opener energising is moved window to relay 1 transmitted signal is opened; If gas concentration further increases, processor STC89C52 makes scavenger fan energising operation reach the effect of rapid reduction gas concentration will to relay 2 transmitted signals.After gas concentration reduces, processor STC89C52 will first make scavenger fan power-off out of service according to gas concentration setting value, then controls window opener by Window closing.
Below only described ultimate principle of the present utility model and preferred implementation, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection domain of the present utility model.
