Gas detector and alarm method

Abstract

The invention provides a gas detector and an alarm method. The method comprises that when at least one of a vibration inductor, a voltage monitor unit and a calibration equipment detection unit of a transmitter and a photoelectric sensor of a sensor meets a preset fault alarm condition, a fault alarm unit of the transmitter is driven to give an alarm. According to the gas detector and the alarm method provided by embodiments of the invention, abnormal conditions which may occur to the transmitter, an air inlet of the sensor and connection lines between the transmitter and the sensor, and non-standard calibration are monitored through the vibration inductor, the voltage monitor unit, the calibration equipment detection unit and photoelectric sensor, so that the accuracy and stability of the gas detector is prevented from being influenced by various factors, the operational stability of the gas detector is improved, and the user safety is effectively ensured.

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.
