Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0040] The modular intelligent gas detection device of the present invention at least includes a main control module and a sensor module, both of which can exchange data. The sensor module can be equipped with sensor probes suitable for different gases for different detection gases. The main control module first reads the rom information of the sensor head 6, judges the type of gas to be detected, then sends a detection control signal to the gas sensor module, and searches the FLASH of the main control module (1) for the corresponding ID according to the ROM information. Detect parameters, and use them as parameters to perform AD conversion and concentration calculation on the detection result signal returned by the curre...

Abstract

The invention discloses a gas detecting device for measuring the concentration of gas. The gas detecting device comprises a main control module, a display module, an input module, an output module, a safety grid module, a sensor module and a power module. In specific implementation, the gas detecting device is formed by lamination of three layers of a display board, a control board layer and a power board layer, and is externally connected with a sensor probe which can be used for detecting different gases. The gas detecting device disclosed by the invention also supports networking with an upper computer and can support multi-gas and multi-range detection.

Description

technical field [0001] The invention relates to a modular intelligent gas detection device for detecting gas concentration, belonging to the technical field of gas concentration testing. Background technique [0002] The application fields of gas detection devices are becoming more and more extensive, especially in the field of combustible gas, toxic gas and other gas detection fields, the application number of gas sensor nodes is already considerable, and, in the next 20 years, the demand market for gas detection devices will further increase. expand. Therefore, how to improve the practicability of sensors at the sensor platform level, improve the versatility of sensor monitoring systems, and how to reduce costs and improve reliability has become an urgent need in this field. [0003] The current gas detection device has relatively perfect detection technology for different gases. Basically, the separation of the sensor probe and the host is realized. The probe can be repl...
