Both the A-point oil pressure detector 11 and the B-point oil pressure detector 12 are composed of a pressure sensor 13 and a pressure transmitter 14. The pressure sensor 13 is embedded and installed at the inner top surface of the underground oil pipeline, and the pressure transmitter 14 is fixedly installed at the top of the pressure sensor 13. The pressure sensor 13 and the pressure transmitter 14 are respectively located underground and above the ground. The pressure sensor 13 and the pressure transmitter 14 in the A-point oil pressure detector 11 are respectively the pressure sensing A-point and the pressure transmitting A-point, and the pressure sensor 13 and the pressure transmitter 14 in the B-point oil pressure detector 12 are respectively the pressure sensing B-point and the pressure transmitting B-point. By setting the A-point oil pressure detector and the B-point oil pressure detector on both sides of the pumping pipeline of the road oil tanker, the pressure sensor 13 is used to monitor the oil pressure on both sides of the pipeline pumped to the road oil tanker in real time, so that whether there is a leakage situation can be obtained by using the oil pressure difference.

[0023] The detection and processing system 2 includes a detector main body 21 electrically connected to the pressure transmitter 14, the outside of the detector main body 21 is electrically connected to an automatic alarm 22, the detector main body 21 is wirelessly connected to the Internet of Things cloud platform 24 through an NB-IoT module 23, and a signal processing module and an automatic control module are fixedly installed inside the detector main body 21. The automatic alarm 22 is automatically opened and closed under the action of the automatic control module. When pumping to the road oil truck, the road oil truck pumping pipeline is opened, and the detection and processing system 2 is closed at the same time to prevent the start and stop of the pump, the adjustment of the valve, etc. from causing negative pressure waves, thereby reducing the false alarm rate. After pumping to the road oil truck, the road oil truck pumping pipeline is closed, and the detection and processing system 2 is opened at the same time.
