Automatic control system for wireless control of cold saw movement mode Technical Field The invention belongs to the field of automatic control, and particularly relates to an automatic control system for a wireless control cold saw movement mode. Background The conventional cold saw control system is used for a long time because of its simplicity, stability, cheapness and easiness, and has realistic rationality in low automation requirement and single machine operation scene, but with the improvement of safety requirement, production efficiency and multi-equipment cooperative requirement, the limitation is gradually revealed. The conventional cold saw control system has the following defects: In conventional cold saw control systems, there is typically no explicit interlock mechanism, and multiple cold saws may be activated or mishandled simultaneously at the same time, resulting in collision or synchronization problems between the devices, thus raising safety concerns. This can affect the safety of operators and equipment, increasing the risk of potential equipment damage and personnel injury. Instruction control of conventional cold saw control systems generally relies on manual operation, lacking real-time status feedback and an intelligent automatic adjustment mechanism. When a plurality of devices are operated, the manual monitoring and adjusting accuracy is low, and the problems of uneven sawing, equipment failure and the like are easily caused. In addition, the operator's real-time knowledge of the status of the equipment is not comprehensive enough, and may cause failures to be ignored, affecting production efficiency and equipment life. The control of the different cold saw devices may not be adequately coordinated automatically, lacking precise synchronization control between the devices. For example, when multiple cold sawing devices perform synchronous sawing, the lack of closed-loop control of the position causes inconsistent movement, which affects sawing quality and may even lead to damage to the devices or inefficiency in production.
