Benefits of technology

This new type of hydrauled vehicle safety system uses an electronic device called Digital Hydraulics (DAH) that controls various functions such as lifting weights or adjusting suspension settings for vehicles. Unlike previous systems where there were separate components like pumps and valves, this DAH eliminated any issues with conventional methods involving multiple parts - including pipes, hoses, wires, etc., making them more accurate than previously possible due to their distributed nature. Overall, these technical improvements make the overall performance of the DHAZ-based hydrous car's safety system better compared to older designs.

Problems solved by technology

This patented describes how hydrauled supports can move around during operation but they may have issues due to their own weight and unstable conditions caused by factors like unevenness over ground level. To solve this problem, it proposes developing autonomous controls called Automatic Control Systems (ACS) based upon signals from various types of sensory devices installed throughout them. However, current methods require manual interventions when needed, leading to decreased productivity and increased costs associated with maintenance tasks.

Abstract

The embodiment of the invention provides a digital hydraulic support and a control method thereof, and relates to the technical field of coal mine machinery and control. The support comprises a main controller, a support base, a support top beam, a shield beam, a face guard, a pushing jack, a face guard jack, a balance jack and a support stand column, wherein a tilt angle sensor is further arranged on the support base, the pushing jack, the face guard jack and the support stand column respectively adopt digital oil cylinders, and the tilt angle sensor and the digital oil cylinders are electrically connected with the main controller respectively. The digital oil cylinders accurately act to specific positions according to received driving signals, so that the hydraulic support has the digital accurate control capability, and the accurate control of the hydraulic support and the machine following automation degree of the hydraulic support can be conveniently increased.
