Embodiment Construction

[0030] figure 1 Shows the structure of the mother-child gas sensor of the present invention, including: a plurality of slave machine gas sensors 1, used to respectively detect the slave machine gas concentration; a master machine gas sensor 2, used to detect the master machine gas concentration, and through the connection line to monitor The substation 3 uploads the gas concentration signal and receives the gas concentration signal transmitted from the monitoring substation 3; among them, the gas sensor 1 of the slave machine communicates with the gas sensor 2 of the master machine wirelessly, and the gas concentration signal detected by the gas sensor 1 of the slave machine is wirelessly communicated. Send it to the gas sensor 1 of the parent machine, and then send it to the monitoring substation 3 by the gas sensor 2 of the parent machine via the signal line.

[0031] The gas sensor 2 of the master machine of the present invention is connected with the monitoring substation ...

Abstract

The invention discloses a primary-secondary type gas sensor, comprising a plurality of secondary machine gas sensors and a primary machine gas sensor. The secondary machine gas sensors are used for detecting gas concentration of secondary machines; the primary machine gas sensor is used for detecting gas concentration of a primary machine and uploads a gas concentration signal to a monitoring sub station by a connecting line and receives a gas concentration signal downloaded from the monitoring sub station, wherein, the plurality of the secondary machine gas sensors communicate with the primary machine gas sensor in a wireless way; the gas concentration signal detected by the secondary machine gas sensors is transmitted to the primary machine gas sensors in a wireless way, and then is uploaded to the monitoring sub station by the primary machine gas sensor through a signaling line. In the invention, multi-point simultaneous and continuous monitoring can be carried out in a certain space range, and real-time transmission can be realized.

Description

technical field [0001] The invention relates to a gas sensor, in particular to a mother-child type gas sensor used underground. Background technique [0002] The existing technology can realize continuous 24-hour measurement of a certain fixed point underground, but cannot carry out all-round continuous measurement of a certain space. However, the distribution of gas in a certain underground space is not uniform due to the influence of geographical structure. For gas monitoring during excavation (moving), due to the inconvenience of cable connection, the current method is to use a portable (or airborne) gas monitor for monitoring. However, its data has not realized the "upload function", and the information cannot be shared. Before or after the disaster, due to the lack of data, the monitoring data has no practical significance for disaster prevention and rescue. [0003] In addition, as far as the basic working process of existing methane sensors is concerned, they all c...
