Abstract

The invention discloses a system suitable for automatically acquiring pumping test parameters. Comprising a water level measurement unit, a temperature measurement unit, a flow measurement and display unit, a central processing system, a parameter centralized storage unit, a parameter centralized display unit, a flow adjusting device, a signal expansion slot, a power expansion slot, a signal line, a power line and a communication line. The pump flow is adjusted on site through the flow adjusting device to achieve on-site centralized display of different water level drop depths and parameters. And each parameter is in remote signal transmission through a 4-20mA standard signal. The signal expansion slot and the power expansion slot can conveniently adjust the number of measurement parameter channels, each unit adopts a unified power supply for power supply and signal communication, and the system is established in a modularized manner. Single-hole steady flow and non-steady flow water pumping and group hole water pumping test parameter automatic acquisition and storage are realized by expanding the number of channels, the field labor intensity can be greatly reduced, the operation is simplified, and the parameter measurement precision and accuracy are improved. The water pumping test scheme can be conveniently adjusted on site according to the water yield characteristic of the aquifer.
