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.
