Patent number: 11954842Abstract: The invention discloses a powder leakage monitoring device and a powder leakage monitoring method. The powder leakage monitoring device comprises light field camera, 3D PTZ (3-Dimensional Pan/Tilt/Zoom) and computer. Wherein, the light field camera records original light field images of monitored area; the 3D PTZ under the light field camera adjusts the shooting angle of the light field camera when it rotates according to the set direction; and the computer respectively connects to the light field camera and the 3D PTZ, which generates refocused images corresponding to the original light field images, and determines the spatial coordinates of the powder leakage point and the hazard range of the powder leakage in the monitored area according to the refocused images and the shooting angle. Therefore, the range and accuracy of powder leakage monitoring are both increased by using this invention.Type: GrantFiled: October 31, 2022Date of Patent: April 9, 2024Assignee: HUANENG NANJING JINLING POWER GENERATION CO., LTD.Inventors: Yudong Liu, Lei Wang, Kai Shi, Yong Xia, Xudong Si, Dongfang Li, Xuedong Liang

Patent number: 11761334Abstract: An apparatus includes a current excitation source, a roadheader telescopic protection cylinder, an electric rotating apparatus, auxiliary cutting teeth, a cutting head entity, a transmission shaft, an optical fiber ring protective housing, an optical fiber ring, an optical fiber current sensor control unit and a recovery electrode. The apparatus transmits an auxiliary current Ie and a monitoring current Id to a coal seam. The auxiliary current Ie and the monitoring current Id are homologous currents that are incompatible, and the auxiliary current Ie squeezes the monitoring current Id, so the monitoring current Id monitors the environment of the coal seam. The monitoring current Id flows to the coal seam as, and a return current If flows through the transmission shaft and a roadheader expansion part. The optical fiber ring measures the return current If, when the roadheader is heading forward and encounters abnormal geological bodies.Type: GrantFiled: January 17, 2022Date of Patent: September 19, 2023Assignee: CHINA UNIVERSITY OF MINING AND TECHNOLOGYInventors: Shaoyi Xu, Zhencai Zhu, Wei Li, Wenting Lu, Gang Shen, Songyong Liu, Fangfang Xing, Hongxiang Jiang, Lei Si

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
