Embodiment Construction

[0037] The invention provides a separate sensor device and an on-line gas detector, which separates the existing sensor unit from the control board, and keeps the function of the control board part unchanged, so that the sensor unit can be mass-produced without considering the type of detector, the sensor The circuit of the unit is different according to the type of sensor. When performing calibration, only the sensor unit needs to be calibrated, and the whole machine does not need to be calibrated. In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Abstract

The invention discloses a separate sensor device and an on-line gas detector. The on-line gas detector comprises a detector main body, a plurality of connectors and a plurality of separate sensor devices, wherein each separate sensor device is installed inside any connector, a signal pin of the separate sensor device is inserted into an adapting interface of the connector and electrically connected correspondingly, and the adapting interface of the connector is inserted into an external interface of the detector main body; and each separate sensor device collects a target gas and the surrounding temperature, outputs a corresponding concentration AD value and temperature AD value and transmits to the detector main body through the connector. The separate sensor device is formed through integrating the functions of gas detection, AD collection, temperature detection and storage together, and the separate sensor device can be directly replaced when a gas sensor breaks down or fails, thereby solving a problem of inconvenient sensor replacement of the existing on-line gas detector.

Description

technical field [0001] The invention relates to the technical field of gas monitoring, in particular to a separate sensor device and an online gas detector. Background technique [0002] The rapid development of China's economy has promoted the improvement and upgrading of infrastructure. High-speed rail and urban utility corridors are all products of China's rapid economic development. The detection of the use environment of urban pipe corridors and tunnels should not be underestimated. The measurement of environmental parameters can provide important references for relevant personnel and effectively prevent the occurrence of safety accidents. [0003] At present, most online gas detectors are integrated, integrating the sensor and the control unit. This type of detection instrument occupies a large share in the market. The traditional on-line gas detector mainly amplifies the electrical signal generated by the sensor, collects data through the ADC, and then converts the ...
