Mr. Chow

The application fields of dh Ningbo Hongde Technical Research and Training Center are currently widely used in various industries such as steel, petroleum, chemical industry, electric power, building materials, machinery manufacturing, automobiles, textiles, transportation, environmental protection and culture and entertainment at home and abroad. It can be roughly summarized into the following categories.
Logic control of switching values
This is the most basic and extensive application field. It replaces the traditional relay circuit to realize logic control and sequence control. It can be used to control a single device or Multi-machine group control and automated assembly lines. Such as injection molding machines, printing machines, stapling machinery, combination machine tools, grinders, packaging production lines, electroplating lines, etc.
Analog quantity control
In the industrial production process, there are many continuously changing quantities, such as temperature, pressure, flow, liquid level and speed, etc., which are all analog quantities. In order for the programmable controller to process analog quantities, /D conversion and D/ conversion between analog quantities and digital quantities (D) must be implemented. Manufacturers all produce matching /D and D/ conversion modules to enable programmable controllers to be used for analog control.
Motion control
Can be used to control circular motion or linear motion. In terms of control mechanism configuration, in the early days, it was directly used to connect switching quantities/modules to position sensors and actuators. Nowadays, dedicated motion control modules are generally used. Such as single-axis or multi-axis position control modules that can drive stepper motors or servo motors. Almost all the products of major manufacturers in the world have motion control functions and are widely used in various machinery, machine tools, robots, elevators and other occasions.
Process Control
Process control refers to the closed-loop control of analog quantities such as temperature, pressure, flow, etc. As an industrial control computer, it can program various control algorithms and complete closed-loop control. D adjustment is a commonly used adjustment method in general closed-loop control systems. Both large and medium-sized ones have D modules, and many small ones now also have this functional module. D processing generally involves running a dedicated D subroutine. Process control is widely used in metallurgy, chemical industry, heat treatment, boiler control and other occasions.
Data processing
Modern has functions such as mathematical operations (including matrix operations, function operations, logical operations), data transmission, data conversion, sorting, table lookup, bit operations, etc., which can complete data collection, analysis and deal with. These data can be compared with the reference values stored in the memory to complete certain control operations. They can also be transmitted to other smart devices using the communication function, or they can be printed and tabulated. Data processing is generally used in large-scale control systems, such as unmanned flexible manufacturing systems, and can also be used in process control systems, such as some large-scale control systems in papermaking, metallurgy, and food industries.
Communication and networking
Communication includes communication between devices and communication with other smart devices. With the development of computer control, factory automation networks have developed rapidly. Various manufacturers attach great importance to the communication function and have launched their own network systems. The newly produced ones all have communication interfaces, making communication very convenient.
