The present invention discloses a soft soil foundation single-hole depth air compression drainage device and working method thereof, comprising an air compression pipe and a water drainage pipe. A water drainage cavity body and an air diffusion cavity body are buried respectively in a soft soil foundation, and the air diffusion cavity body is located below the water drainage cavity body. Connecting to the air diffusion cavity body, the air compression pipe protrudes out of ground surface along a vertical direction of the soft soil foundation and communicates with an inflation pump; connecting to the water drainage cavity body, one end of the water drainage pipe protrudes to the bottom of the water drainage cavity body, and the other end protrudes out of the ground surface, thus achieving deep drainage and a drainage consolidation time of the deep soft soil foundation is shortened.

The present disclosure discloses a digital hydraulic assisted braking system with a high dynamic response and a control method thereof. The system includes a two-position two-way digital switch valve A, a controller, an electromagnetic two-position two-way proportional reversing valve, a two-position two-way digital switch valve B, a displacement detection system, and a pressure detection system. When a vehicle starts, a control system of the present disclosure maintains a preload state and responds to a braking at any time. During an emergency braking, the braking system is open. When the vehicle is shut down, the braking system is closed. Compared with an existing braking method, by implementing the braking method of the present disclosure, a braking response time is greatly shortened, a dynamic performance of a braking response period is improved, and a safety of vehicle braking is further guaranteed.

Digital hydraulic assisted braking systems with high dynamic response and control methods thereof

The present disclosure discloses multi-mode hydraulic braking systems and control methods thereof. The system includes a two-position three-way digital switch valve, an electromagnetic three-position three-way proportional reversing valve, a controller, a pressure detection system, a speed detection system, and a displacement detection system. The controller intelligently switches a digital braking mode, a composite braking mode, and an anti-lock braking mode after collecting a brake signal through the pressure detection system and speed detection system in real time. The present disclosure integrates an electro-hydraulic proportional control technology with the electromagnetic three-position three-way reversing valve as a control element and a digital hydraulic technology with a digital switch valve as a control element and takes into account an anti-lock function on the basis of digital and composite braking modes to ensure safety of emergency braking and improves versatility of the braking system by the controller intelligently switching the operating modes.
