This invention relates to the field of robotic arm control technology, specifically a control system and method for a chemical emergency robotic arm based on intelligent perception. The system includes: a data acquisition unit for collecting environmental data from a chemical scenario and obtaining an initial depth image of the target area of ​​the chemical equipment to be operated; performing multi-sensor fusion processing on the environmental data and the initial depth image to obtain corresponding gas concentration information, obstacle location information, and image data of the target area; and a hazard assessment unit for inputting the gas concentration information, obstacle location information, and the current posture information of the robotic arm into a hazard assessment model to obtain the corresponding operational hazard level and the distance to the nearest obstacle. This invention uses a target recognition model to accurately obtain the location information of the target area and combines this with data such as the operational hazard level and obstacle location information to generate obstacle avoidance paths and operational instructions. This enables the robotic arm to intelligently avoid obstacles in complex environments while ensuring smooth operation.

The present invention provides an electromechanical, hydraulic, and gas multi-field coupled rotary percussion drilling system, including a control system, a hydraulic feed subsystem, a high-speed variable plunger motor rotation subsystem, a low-speed cycloidal motor rotation subsystem, a pneumatic impact subsystem, and a comprehensive power integration subsystem. The hydraulic feed subsystem is used to control the feed and pull-out of the drill; the high-speed variable plunger motor rotation subsystem and the low-speed cycloidal motor rotation subsystem are respectively used to drive the rotation of the main shaft of the drilling rig at different speeds; the pneumatic impact subsystem is used to control the high-frequency impact of the pneumatic impact drill; the comprehensive power integration subsystem is used to integrate and transmit the comprehensive power of the hydraulic feed subsystem, the high-speed variable plunger motor rotation subsystem, the low-speed cycloidal motor rotation subsystem, and the pneumatic impact subsystem. The present invention can realize a large range of stepless speed regulation and rotation, multiple torque outputs, high-frequency impact, load-sensitive regulation, and intelligent drilling pressure regulation during the process of drilling and breaking rocks, effectively overcoming drill jamming and drilling deviation.
