Abstract
The utility model relates to the technical field of security and protection, and provides a gas leakage alarming device. The gas leakage alarming device is characterized by comprising a CO (Carbonic Oxide) sensor, a hydrogen sensor, an alkanes sensor, three signal amplifiers, three A/D (Analog-to-Digital) converters and a single chip RCM5700, wherein the CO sensor, the hydrogen sensor and the alkalines sensors are all connected to independent A/D converters through independent signal amplifiers; the three A/D converters are all connected with the single chip RCM5700; and the single chip RCM 5700 is connected with a buzzer, an alarm light, a display, a solenoid valve and a crystal oscillator. The device is applied to perform alarming once gas leakage occurs.
Description
Technical field
The utility model relates to technical field of security and protection, and a kind of coal gas body leakage warning device is provided.
Background technology
All accidents that people cause in the face of gas leakage threaten, just genuine neither one is solution thoroughly? according to relevant expert's introduction, using fuel gas alarm is one of important means that tackles the invisible killer of combustion gas.Combustion gas the expert point out, gas leakage or toxic emission and a large amount of carbon monoxide that produces is the root of combustion gas poisoning thing response, as adopt useful Fuel Gas Leak Alarm and just can be warned timely.Relevant department reaches a conclusion equally through long-term test, and fuel gas alarm prevents efficient the reaching more than 95% that the anthracemia accident occurs.
Summary of the invention
The purpose of this utility model is to provide coal gas body leakage warning device a kind of simple in structure, with low cost.
The utility model is by the following technical solutions to achieve these goals:
A kind of coal gas body leakage warning device, it is characterized in that: comprise CO sensor, hydrogen gas sensor, alkanes sensor, 3 signal amplifiers, 3 A/D converters, single-chip microcomputer RCM5700, described C0 sensor, hydrogen gas sensor, alkanes sensor all connect independent A/D converter by independent signal amplifier, described 3 A/D converters all connect single-chip microcomputer RCM5700, and described single-chip microcomputer RCM5700 is connected with hummer, alarm lamp, display, solenoid valve, crystal oscillator.
In the such scheme,Described CO sensor adopts NG-CO-001 type galvanochemistry CO gas sensor.
The principle of work of system is to utilize gas sensor that gas concentration is transformed to mV level analog current signal, and amplifier filters undesired signal through low-pass filtering and delivers to A/D converter after signal is amplified, and is transformed into digital quantity and send main control chip to carry out data analysis.Because the main character of gas leak gas out can be divided into 2 kinds of poisonous gas and inflammable gass, so the utility model adopts the different sensor of 3 properties, it is processed respectively.NG-CO-001 type galvanochemistry CO gas sensor mainly is that toxicity and flammable CO gas are carried out accurate individual event detection.Other 2 kinds of sensings detect the inflammable gas of 2 classes wherein respectively.
Behind RCM5700 implantation software program, control the operation of whole circuit.Airborne gas concentration signal enters single-chip microcomputer simultaneously, and single-chip microcomputer is analyzed it, and output signal is to display, controls it and points out out the air quality of 5 grades such as " good, excellent, good, in, poor " to point out.When induced signal reaches any one hazardous location (comprising combustable gas concentration explosive area and poisonous gas concentration explosive area) value of setting, main control chip drives output signal and reports to the police, the control display device demonstrates the respective air quality grade and is " poor ", drive hummer and send the sound, warning LED is luminous, controls simultaneously closed electromagnetic valve.To allow the monitor staff process.After fault was got rid of, the complete state of alert of automatically getting back to of reporting to the police was waited for next time and being reported to the police
The utility model can effectively be monitored gas leak because adopted above technical scheme.
