What are The control Systems of The Concrete Mixing Plant?
Concrete mixing station is a kind of equipment used to produce concrete, and its control system is a key component to ensure the normal operation of the mixing station. The control system of ready mix wet concrete mixing plant can be classified and divided according to different requirements and technical levels. The following will introduce some common types of concrete mixing station control system.
Types of concrete mixing plant control system
1. Manual control system
Manual control system is a basic control mode. Operators control various parts of the cement mixing station, such as conveyor belt, mixer and discharging device, by manually controlling switches and buttons. This control method is simple and intuitive, but it requires operators to have certain experience and skills, and the work efficiency is relatively low.
2. Automatic control system
Automatic control system is a way to realize automatic control of concrete mixing station by using electronic control equipment and sensors. Through the preset program and parameters, the automatic control system can realize the automatic control and monitoring of the concrete batching plant, and improve the work efficiency and production quality. The automatic control system usually has a programmable controller (PLC) and a touch screen interface, which is easy to operate and can realize accurate control of all parts of the ready mixed concrete mixing plant.
3. Computer control system
Computer control system is further developed on the basis of automatic control system, which uses computer software and hardware to realize comprehensive control and management of mixing station. Computer control system can realize more complex functions, such as production planning, data analysis and report generation. It has high flexibility and expansibility, and can meet the control requirements of dry concrete mixing stations with different scales and requirements.
4. Distributed control system
Distributed control system is a control system that distributes control functions on multiple nodes, and all nodes communicate and cooperate through the network. The distributed control system can improve the reliability and stability of the system, and also realize the distributed monitoring and control of the concrete mixing station.
In a word, the control system of concrete mixing station is various, including manual control system, automatic control system, computer control system and distributed control system. Different control systems have different characteristics and scope of application, so the appropriate control system type can be selected according to specific needs. According to the scale and requirements of the cement mixing plant, a suitable control system can be selected to realize efficient, stable and reliable concrete production.
Application of concrete mixing station control system
1. The manual control system is suitable for small concrete mixing stations or scenes with low requirements for automation. Operators need to manually operate switches and buttons to control the operation of the mixing station, which is simple and intuitive, but the work efficiency is relatively low.
2. Automatic control system is one of the common control methods at present. It adopts electronic control equipment and sensors, and realizes the automatic control and monitoring of the cement mixing station through preset procedures and parameters. Automatic control system is usually equipped with programmable controller (PLC) and touch screen interface, which is easy to operate, and can realize accurate control of all parts of the mixing station and improve production efficiency and product quality.
3. Computer control system is further developed on the basis of automatic control system, which uses computer software and hardware to realize comprehensive control and management of mixing station. The computer control system has more complex functions, such as making production plans, analyzing data and generating reports. It has a high degree of flexibility and expansibility, which is suitable for large concrete mixing stations and can meet complex production requirements.
4. Distributed control system is a control method that distributes control functions on multiple nodes, and all nodes communicate and cooperate through the network. The distributed control system has a high degree of reliability and stability, and can realize the distributed monitoring and control of the concrete batching and mixing station, which is suitable for the scene of large-scale concrete mixing plant or joint operation of multiple mixing stations.
In addition to the above common control system types, there are also some special control systems, such as remote monitoring system and intelligent control system. These systems use advanced communication technology and artificial intelligence algorithm to realize remote monitoring, fault diagnosis and optimal control of mixing station, and further improve production efficiency and automation level.
Advantages of concrete mixing station control system
1. High batching accuracy
The single weighing accuracy is 0.1%, and the system batching accuracy is 0.5%.
2. High degree of automation
Print shift record, ingredient report and alarm function, and automatically set zero and accumulate.
3. Run automation
The running program of the central control machine automatically starts, automatically debugs, and automatically displays the running status of the system on the screen.
4. Simple operation
The system provides fully automatic and single automatic operation modes. In fully automatic mode, without human intervention, the microcomputer automatically completes all the batching process and prints it in real time.
5. High safety factor
Reliable operation, compact structure and high safety factor.
6. Convenient maintenance
Modular structure is adopted between the internal parts of the control system of the mixing station, and the contact pieces are convenient to connect, repair and maintain.
