Patent number: 10975695Abstract: A hydraulic support monitoring a support pose in real time based on an inertia measurement unit (IMU) and a detection method thereof. In the hydraulic support, IMU sensors are separately mounted on a roof beam, a rear linkage, and a base, and an auxiliary support pose monitoring system is disposed. Each IMU sensor measures movement states of the roof beam, the rear linkage, and the base of the support in real time, and the support pose monitoring system processes the movement states to monitor a support pose of the hydraulic support in real time. Especially, it can be technically determined whether the hydraulic support is adequately lowered, moved or raised, thereby effectively reducing the labor intensity of workers and improving the working efficiency of the hydraulic support.Type: GrantFiled: June 18, 2019Date of Patent: April 13, 2021Assignees: CHINA UNIVERSITY OF MINING AND TECHNOLOGY, XUZHOU GOLDFLUID HYDRAULIC TECHNOLOGY DEVELOPMENT CO., LTD.Inventors: Zhongbin Wang, Xuliang Lu, Chao Tan, Haifeng Yan, Lei Si, Xingang Yao

Patent number: 10830044Abstract: A system and method for remotely locating a communication error support for hydraulic supports. The system includes a control panel, a support controller, a data converter, and two support drivers of the same type. Each support driver has two bus interfaces. The control panel transmits a control command to the data converter in a form of a WiFi signal. The data converter converts the WiFi signal into a message signal and transmits the message signal to the support controller. The support controller transmits the control command to the two support drivers, respectively. The support drivers transmit the command through CANH twisted pairs and CANL twisted pairs. When a bus for transmitting the command of a certain node has an error, the support controller calculates the fault node according to a formula n = p ? t 8 ? m , and feeds back the fault node onto the control panel.Type: GrantFiled: June 18, 2019Date of Patent: November 10, 2020Assignees: CHINA UNIVERSITY OF MINING AND TECHNOLOGY, XUZHOU GOLDFLUID HYDRAULIC TECHNOLOGY DEVELOPMENT CO., LTD.Inventors: Chao Tan, Zhongbin Wang, Hongya Zhou, Lei Si, Xinhua Liu, Xuliang Lu, Xiaoyu Li, Bowen Liu, Yue Wu, Honglin Wu
