The invention provides a mining digital program control scheduling communication method and system, the system comprises a scheduling host at the bottom of a main roadway and static communication positioning base stations in auxiliary roadways, firstly, an underground three-dimensional environment map is created, and secondly, a carry-on communicator of a miner transmits voice information to a nearby communication base station; the latter identifies the speaker identity and the content as requesting communication or non-requesting communication. If the communication is request communication, the system converts the content into digital information and transmits the digital information to the digital stored program control exchange through the ring network exchange to realize effective communication above and below the well; and if the communication is not requested, activating the adjacent positioning base station, measuring the distance and transmitting the information to the scheduling host. And the dispatching host positions the accurate position of the speaker on the three-dimensional map according to the distance information of the two base stations, and outputs a result to the main control center. The system not only effectively improves the intelligent management and scheduling capability, but also enhances the safety and emergency response capability of a mine, and provides a solid foundation for the modern development of coal mine operation.

The invention belongs to the technical field of robot control, and particularly relates to a multidirectional underwater robot obstacle avoidance method and related equipment, and the method comprises the steps: transmitting detection sound waves in different detection directions in different time periods; acquiring echo conditions of each detection direction, judging whether obstacles exist in a plurality of detection directions according to the echo conditions, and if the obstacles exist in the plurality of detection directions, determining the obstacle distance between the obstacle and the underwater robot in the corresponding detection direction and the position of the obstacle based on the echo data reflected in each detection direction; determining the obstacle avoidance level of the obstacle in each detection direction according to the obstacle distance and the planned path of the underwater robot; and performing obstacle avoidance on the underwater robot in each detection direction according to the obstacle avoidance level and position of the obstacle in each detection direction. The obstacle avoidance requirement can be met more quickly based on short-time multi-directional detection, and the task execution efficiency can be improved; and obstacle avoidance is carried out based on the obstacle avoidance level of the obstacle, so that the emergency capability is stronger.

This utility model discloses an intelligent automatic uncoupling robot system for railway freight cars, including an information system, a monitoring system, an uncoupling robot trolley, and an early warning system. The information system is used to collect freight car information, confirm the uncoupling robot trolley that needs to be uncoupled according to the plan, and calculate the time required for the freight car to move from the uncoupling position to the corresponding uncoupling robot trolley position. The monitoring system is used to monitor the movement of the uncoupling robot trolley and determine whether there are any abnormalities in the uncoupling operation and uncoupling conditions. The uncoupling robot trolley is used for autonomous driving, autonomously determining the uncoupling position and performing the uncoupling operation, autonomously returning to its original position, monitoring and sending the status information of the uncoupling robot trolley, receiving control commands, and adjusting the status of the uncoupling robot trolley according to the status information or control commands. The early warning system is used to receive and provide feedback on abnormal information of the uncoupling operation and abnormal information of the uncoupling conditions of the uncoupling robot trolley.

This utility model discloses a portable, universal hydraulic cylinder disassembly device for field use, belonging to the field of hydraulic cylinder repair technology. It includes a main body with a lifting assembly at the top. The lifting assembly includes a lifting frame vertically slidably mounted within the main body, and a torque converter at the bottom. Clamping assemblies are connected to both the lifting frame and the torque converter. The two clamping assemblies are used to clamp cylinder head A and cylinder barrel B respectively. The torque converter drives the connected clamping assemblies to twist cylinder head A or cylinder barrel B. Compared with existing technologies, this portable, universal hydraulic cylinder disassembly device eliminates the need for manual disassembly of hydraulic cylinders using tools or large horizontal disassembly machines, reducing the time spent disassembling hydraulic cylinders and avoiding deformation and damage caused by uneven force on the hydraulic cylinder. It also eliminates the traditional step of disassembling by hammering.

The utility model provides a fixed insulation structure after cable wiring, and relates to the technical field of fixed insulation structures. The main body seat is made of a plastic material, and a fixing assembly is mounted on the main body seat. An auxiliary assembly is arranged, through the arrangement of the auxiliary assembly, after a first threaded rod is damaged, a locking screw rod can be unscrewed, a second threaded rod can be rotated, a connecting block moves downwards under extrusion of the second threaded rod, fixing and sealing of a cable can be completed, and the emergency capacity is high; the cable fixing insulation structure is provided with the mounting assembly, through the arrangement of the mounting assembly, a fixing screw rod can be prevented from loosening under the extrusion action of an auxiliary block, the mounting stability is ensured, and the problem that although an existing fixing insulation structure can fix a cable through a thread adjusting mode, on one hand, after a thread adjusting piece is damaged, on the other hand, the cable cannot be fixed easily is solved. The problems that in the prior art, a cable cannot be fixed, the cable is prone to disengagement when pulled, overall replacement needs to be carried out, and cost is high are solved.
