A low-power wireless communication system and detection communication method for a shaft wall detection terminal

Abstract

The invention discloses a low-power-dissipation wireless communication system of a well wall detection terminal and a detection communication method. The system comprises a plurality of wireless monitoring terminal devices arranged on a well wall and a portable wireless collecting device; each wireless monitoring terminal device comprises a first wireless communication assembly, a real-time clock module, a first battery power supply module, a monitoring driving module and an external sensor which are connected with a first single-chip microcomputer minimum system; the portable wireless collecting device comprises a second wireless communication assembly, a storage device module, a second battery power supply module and a keyboard liquid crystal display module which are connected with a second single-chip microcomputer minimum system. In order to reduce power dissipation of wireless monitoring terminals, the wireless monitoring terminals monitor and record well wall parameters in a timed monitoring mode; in order to eliminate power dissipation generated by communication of the wireless monitoring terminals, the wireless communication assemblies of the system are in the closed state all the time. Only after a set awakening time arrives, the wireless monitoring terminals will start the wireless communication assemblies intermittently.

Description

Technical field [0001] The invention relates to the technical field of low power consumption wireless communication, in particular to a low power consumption wireless communication device and a detection communication method of a borehole detection terminal. Background technique [0002] Coal mine shaft is the main throat of coal mine production. In order to ensure the construction quality of the shaft wall, it is necessary to monitor the relevant working conditions of the shaft wall during the construction of the wall, such as the temperature change of the frozen soil in and after the concrete is poured, and the shaft wall Internal stress, shaft wall displacement, etc.; after the completion of wall construction, it is still necessary to carry out long-term monitoring of the working condition of the shaft wall. [0003] Compared with monitoring technologies in other fields, the implementation of shaft wall monitoring faces some special difficulties. [0004] 1) It is inconvenient to...

AI Technical Summary

Problems solved by technology

[0004] 1) It is inconvenient to introduce power supply lines, especially during wall construction;

[0005] 2) The exposed cables in the shaft wall are not easy to protect, such as scraping due to lifting and lowering of the suspension plate, impact damage during blasting, etc.;

[0006] 3) After the monitoring terminal is installed, once the hanging pan falls or rises, it cannot be accessed, and the operation cost of lifting the hanging pan is very high;

[0007] 4) The operation cycle of wall building is long, such as building a 600-meter shaft, the wall building time is often more than one year, so the monitoring terminal is required to be able to run for a long time;

However, this measurement method is not suitable for long-term frequent measurement
