Description

Technical Field

[0001] The present invention relates to the technical field of industrial controllers, and in particular to a control system based on a smart factory. Background Art

[0002] Control systems are widely used in production sites. The requirements for control systems are high speed and high reliability. They need to centrally process information such as Ethernet data generated by user-side devices, decision-making processing results, and data matched by user-side devices in a timely manner. Therefore, system controllers are particularly important.

[0003] The most common existing controller is the PLC programmable edge controller, whose control system mainly consists of a CPU module, input module, output module and programmer. As of now, the programmer can also be used as an expansion unit module, and a memory module is introduced to cooperate with the use of the CPU. The addition of a power supply as a voltage regulator makes the controller a separate entity, realizing remote debugging functions.

[0004] Existing controllers use heat sinks to dissipate heat, but their heat dissipation function is generally poor. Each module is in direct contact with the chassis, and its resistance to impact is poor. Over time, the internal components are easily damaged. During maintenance, since each connector is fixed with screws and the entire circuit uses a common PCB board, maintenance is very difficult. Summary of the Invention

This control system based on a smart factory, on the basis of realizing remote and real-time monitoring of multiple field devices, not only facilitates the disassembly of the installation block with the unit module installed, but also can effectively buffer and release the external impact force exerted on the controller, thereby improving the overall impact resistance and the stability of various performances during long-term use.
