The computer control of the whole set of organic fertilizer production equipment is through the programmable logic controller (PLC). The programmable memory is used for the organic fertilizer processing production line to store the internal program, execute user oriented instructions such as logical operation, sequence control, timing, counting and arithmetic operations, and control various types of machinery or production processes through digital or analog input/output.

Computer control of a complete set of organic fertilizer production equipment

The PLC has the following distinctive features.

1. The whole set of organic fertilizer production equipment is easy to use and programming: concise ladder diagram, logic diagram or statement table and other programming languages are used, so the system development cycle is short and on-site debugging is easy. In addition, the program can be modified online to change the control scheme without removing the hardware.

2. Strong functions and high performance price ratio: There are hundreds of programming elements for users in a computer, which has strong functions and can realize very complex control functions. Compared with the relay system with the same function, it has a high performance price ratio. PLC can realize decentralized control and centralized management through communication networking.

3. The hardware is complete, convenient for users, and has strong adaptability: the computer and PLC products have been standardized, serialized, and modularized, and are equipped with a variety of hardware devices for users to choose. Users can flexibly and conveniently configure the system to form systems with different functions and scales. The installation and wiring of PLC is also very convenient. Generally, terminal blocks are used to connect external wiring. PLC has strong load capacity and can directly drive general solenoid valves and small AC contactors.

After the hardware configuration of the organic fertilizer processing production line is determined, the user program can be modified to easily and quickly adapt to changes in process conditions.
