A gas detector and its alarm method

Abstract

A gas detector and an alarming method therefor. The method comprises: when at least one of a vibration sensor, a voltage monitoring unit and a calibration device detection unit in a transmitter and a photoelectric sensor in a sensor satisfies a pre-set failure alarming condition thereof, driving a failure alarming unit of the transmitter to output an alarm (101). By means of the gas detector and the alarming method therefor, exceptional situations which may occur in a transmitter, a gas inlet of a sensor, a connection cable between the transmitter and the sensor, non-normative calibration, etc. can be monitored in real time by using a vibration sensor, a voltage monitoring unit, a calibration device detection unit and a photoelectric sensor, so as to prevent damage to the accuracy and stability of the gas detector due to various reasons, thereby improving the operation stability of the gas detector, and effectively ensuring the user security.

Description

technical field [0001] The invention relates to the field of industrial detection, in particular to a gas detector and an alarm method thereof. Background technique [0002] Gas detectors include transmitters and sensors, which can be divided into civil-grade gas detectors and industrial-grade gas detectors. Civilian-grade gas Oil drilling, aviation, chemical and other important industrial enterprises. Compared with civilian-grade gas detectors, the stability and safety of industrial-grade gas detectors are more important. Once the industrial-grade gas detector itself fails, the consequences are incalculable. [0003] At present, the stability of industrial-grade gas detectors is higher than that of civilian products, but there is still a lack of regulatory precautions for their own safety. When the gas detector itself fails, such as: artificially destroying the transmitter, artificially blocking the sensor inlet, artificially disconnecting the connection between the senso...

Compared with civilian-grade gas detectors, the stability and safety of industrial-grade gas detectors are more important. Once the industrial-grade gas detector itself loses its function, the consequences are incalculable

[0003] At present, the stability of industrial-grade gas detectors is higher than that of civilian products, but there is still a lack of regulatory precautions for their own safety.

When the gas detector itself fails, such as: artificially destroying the transmitter, artificially blocking the sensor inlet, artificially disconnecting the connection between the sensor and the transmitter, non-standard calibration, etc., it is often not recognized and discovered in time. In turn, the accuracy of the gas detector will deteriorate or it will fail permanently, and there will be a greater potential safety hazard.
