This invention provides a highly integrated underground pressure regulating device, belonging to the field of gas pressure regulating boxes, comprising a ventilation venting signal tower and an underground pressure regulating box. The ventilation venting signal tower is connected to the underground pressure regulating box via a pipeline assembly. The underground pressure regulating box includes a box body and two integrated pressure regulating devices. The box body has two receiving cavities, each containing one integrated pressure regulating device. One side of the box body is connected to a main inlet pipe and a secondary inlet pipe, and the other side of the box body is connected to a main outlet pipe and a secondary outlet pipe. The main inlet pipe, one of the receiving cavities, and the main outlet pipe are connected; the secondary inlet pipe, the other receiving cavity, and the secondary outlet pipe are connected. An inlet valve is installed on each of the main and secondary inlet pipes, and an outlet valve is installed on each of the main and secondary outlet pipes. The purpose is to solve the problem of the large footprint of underground pressure regulating devices. The achieved technical effect is a reduction in the footprint.

The invention discloses an ESC power-on and power-off dormancy durability test method and system, and the method comprises the steps: S1, building a test environment, enabling a to-be-tested ESC vehicle body stabilization system, a network test tool and a VBA message analysis simulation tool to be connected to the same test bench communication network, and deploying a TAE automatic test tool; s2, regulating and controlling the network test tool to enable the network test tool to inject a high load into the test bench communication network, and enabling a bus load rate to be stabilized in a preset target interval; s3, starting a durability test, controlling and activating the VBA message analysis simulation tool by the TAE automatic test tool so that the VBA message analysis simulation tool begins to collect an ESC core message according to a set sampling rate, and starting log recording; s4, the TAE automatic testing tool executes the power-off-dormancy-power-on circulation process according to the preset number of cycles until all cycles are completed, and meanwhile the network testing tool continuously monitors and maintains the load rate stable. According to the method, the ESC communication can be fully, effectively and reliably verified, and the communication fault risk of the ESC under the cyclic dormancy power-on working condition is eliminated.

The utility model provides a kind of self-cleaning structure equipment of siltation-preventing of Yellow River diversion sluice, it is related to sluice siltation-preventing technical field, including sluice, the outside of sluice is provided with silt pumping mechanism;Silt pumping mechanism includes controller, the back of controller is fixedly connected with the front of sluice, the bottom of sluice is fixedly connected with ultrasonic sensor, the inner wall of sluice is fixedly connected with submersible silt pumping pump, the input end of submersible silt pumping pump is through sluice and extends to the inside of sluice, the output end of submersible silt pumping pump is fixedly communicated with transmission pipe.This kind of self-cleaning structure equipment of siltation-preventing of Yellow River diversion sluice, by ultrasonic sensor can detect the thickness of silt accumulation at any time, in combination with submersible silt pumping pump, controller and transmission pipe, can automatically adjust the speed of submersible silt pumping pump according to the thickness of silt, when silt reaches certain thickness, submersible silt pumping pump starts to work and pumps out the silt above, not only reduce the land used due to pumped silt, reduce artificial maintenance cost.
