[0032] Specifically, the pressure acquisition unit 101 includes a flush membrane pressure transmitter, a microprocessor circuit and a wireless communication module. The flush membrane pressure transmitter is electrically connected to the input end of the microprocessor circuit through the pressure transmitter interface circuit, and the output end of the microprocessor circuit is electrically connected to the wireless communication module.

[0033] Optionally, the pressure acquisition unit 101 further includes a power supply management circuit, and the power supply management circuit is electrically connected to the flush membrane pressure transmitter and the microprocessor circuit respectively.

[0034] Optionally, the pressure acquisition unit 101 further includes a USB to serial port circuit, which is electrically connected to the microprocessor circuit, and the USB to serial port circuit is used to write a preset ID into the wireless communication module through the microprocessor circuit.

[0036] Wherein, the power supply management circuit is connected with the USB to serial port circuit, the microprocessor circuit, the pressure transmitter interface circuit and the wireless communication module circuit.

[0037] As mentioned above, this embodiment is aimed at collecting parameters such as oil pressure, casing pressure and hydraulic pressure of equipment such as oil pumping units. Therefore, in this embodiment, the flush membrane pressure transmitter preferably used is the PT2407 flush membrane pressure transmitter.

[0038] Specifically, Figure 3 As shown, Figure 3 This is a schematic diagram of the USB to serial port circuit. The USB to serial port circuit consists of a USB bus adapter chip U4 and a capacitor C15; pin 1 of U4 is connected to the UD+ network; pin 2 of U4 is connected to the UD- network; pin 7, pin 10 of U4 and one end of capacitor C15 are connected to the VDD voltage network; pin 8 of U4 is connected to the TXD network; pin 9 of U4 is connected to the RXD network; one end of capacitor C15 is connected to the GND network to achieve a common digital ground.
