Background technique

Programmable Logic Controller PLC is an electronic system operated by digital operations, which is specially designed for application in industrial environment. Programmable controller PLC adopts a type of programmable memory for user-oriented instructions such as internal storage of programs, execution of logic operations, sequence control, timing, counting and arithmetic operations, and controls various functions through digital or analog input/output. type of machinery or production process. Programmable logic controller PLC is the core part of industrial control.

Existing PLC equipment usually works alone, and when the PLC equipment is unattended, it is difficult for the staff to grasp the real-time operation status of the on-site equipment in time. If personnel cannot respond in time, it may cause greater losses. Therefore, how to remotely understand and control the operating status of on-site equipment in real time is an urgent problem to be solved.

Contents of the invention

The purpose of this utility model is to provide a PLC control system with a mobile phone short message platform. This PLC control system is not only simple in structure, but also enables staff to remotely understand and control the operating status of field equipment in real time.
