Downhole water level monitoring terminal

Abstract

The invention discloses a downhole water level monitoring terminal. The downhole water level monitoring terminal comprises a plurality of water level sensors, wherein the water level sensors are used for transmitting water level signals to a concentrator module through a sensor control module; the concentrator module is used for sending the water level information to an upper computer through an Ethernet; the sensor control module uses a NuMicro M054LBN microprocessor as a main controller; the main controller is connected with a minimum system module, a communication module, a human and machine interaction module and a peripheral sensor module; the communication module consists of an RS-485 interface and a GPIO (general purpose input / output) interface; the concentrator module uses an LPC1768 microcontroller as a main controller; the LPC1768 microcontroller is connected with the minimum system module, the human-machine interaction module and the RS-485 interface. The downhole water level monitoring terminal has the advantages that the remote monitoring and automatic control functions are realized; by adopting the Ethernet and the RS-485 interface for communication, the network speed is high, and the modularizing design of the concentrator and sensor can facilitate the installation, debugging and subsequent maintenance; the design scheme and technical measures are reasonable, and the anti-interference capability is strong.

Description

technical field [0001] The invention relates to the technical field of underground water level detection, in particular to an underground water level monitoring terminal. Background technique [0002] In the process of coal mine production, groundwater can often be seen flowing into roadways and working faces, which is mine water. Mine flooding is one of the main disasters common in coal mines. If the mine water is not discharged in time, underground production may be hindered, and underground safety will not be guaranteed. property is a great threat. Therefore, underground drainage is particularly important. At present, in a few coal mines with automatic drainage equipment installed, the automatic drainage system used is out of touch with the actual situation of the mine, and the control system has weak anti-interference, poor stability, and complicated debugging, resulting in unsatisfactory system operation. Therefore, a system that can remotely monitor the water level ...
