Abstract
The invention relates to a nitrogen dioxide leakage detector which comprises a nitrogen dioxide gas sensor, a temperature detection module, a signal amplifier module, a digital-analog converter, a microprocessor, a monitoring display and an acousto-optic alarm. The technical problem that trace of nitrogen dioxide leakage is difficult to discover in the absence of detection means and easily causes personnel and property loss is solved. Values measured by the sensor are corrected according to the ambient temperature. The effect of temperature on measurement accuracy is eliminated. Leakage is detected automatically. Concentration is displayed in real time. When leakage concentration reaches the maximum allowance, an alarm signal is sent out immediately so as to allow maintainers to handle emergently and take corresponding safeguard measures.
Description
Technical field
The present invention relates to a kind of gas leak detection apparatus, especially for the leak detecting device of inflammable toxic gas nitrogen dioxide.
Background technology
Leak for relatively large nitrogen dioxide, because nitrogen dioxide has penetrating odor, easily be found and can in time take appropriate measures; But if micro-leakage occurs, there is no simultaneously detection means, this leakage is difficult for being found, thereby easily causes personnel and property loss.
Summary of the invention
The invention provides a kind of can the leakage nitrogen dioxide and detect and send acoustic-optic alarm, micro-nitrogen dioxide leaks in the situation that the detection means disappearance is difficult for being found easily to cause the technical matters of personnel and property loss thereby mainly solved.
Technical solution of the present invention:
A kind of nitrogen dioxide Leak Detection warning device, its special character is: comprise nitrogen dioxide gas sensor, temperature detecting module, signal amplification module, digital to analog converter, microprocessor, monitor display and audible-visual annunciator,
Described nitrogen dioxide (NO
2) gas sensor is used for the responsive content of nitrogen dioxide of revealing, its output terminal is connected with the signal amplification module, temperature detecting module is used for responsive environment temperature, its output terminal is connected with digital to analog converter, the output terminal of described signal amplification module is connected with digital to analog converter, the output terminal of described digital to analog converter is connected with microprocessor, and microprocessor is connected with audible-visual annunciator with the detection display device.
The present invention has advantages of:
1, the measured value of sensor has been done correction according to environment temperature, has eliminated the impact of temperature on accuracy of measurement.
2, automatic Leakage Detection situation, display density, when leakage concentration reaches maximum permissible value, send alerting signal immediately in real time, so that the maintainer enters the emergency treatment state, adopts corresponding safety precautions.
Description of drawings
Fig. 1 is the schematic block circuit diagram of nitrogen dioxide Leak Detection warning device.
Embodiment
With nitrogen dioxide (NO
2) gas sensor is placed on the position that gas easily leaks, sensor signal is processed by signal amplification module and digital to analog converter, gas sensor concentration signal and ambient temperature signal that the microprocessor acquisition process is crossed, and concentration data and temperature data are shown, when concentration reaches warning line, drive acoustic-optic alarm and report to the police.
