Concrete batching plant control system, as the center of the entire concrete batching plant system, plays a vital role in the production process.
It directs the orderly operation of the production process of the whole batching plant, controls the materials ratio and accuracy of material proportion, and monitors the real-time situation during production and operation.
In case of any abnormality, it must respond quickly and adjust the system in time in order to ensure the stable and reliable operation of the whole batching plant system, to produce various concrete construction materials with high proportioning accuracy that meet the set target requirements.
What are the components of concrete batching plant control system? How many types are there? How do they work? This article will take the control system of LUTON GROUP concrete batching plant as an example to bring you close contact with the central control system of concrete batching plant.

Components and Types of Concrete Batching Plant Control System
According to the degree of automation, concrete batching plant control system can be divided into two types: fully automatic control system and semi-automatic control system. It is also equipped with manual control to achieve flexible control and control requirements in different situations.
PLC + AD Module + Industrial Computer
Characteristics:
- Data collection and batching control are all executed by PLC.
- The PLC has a large operating load and requires a top PLC.
- The computer does not participate in the control.
Advantages:
- After the PLC collects the data, it processes it on the spot.
- The batching control is completed by PLC, the system is very flexible.
Disadvantages:
- The resolution of the PLC is not high.
- Need to use signal amplifier, large error, poor anti-interference.
- The PLC has a large amount of calculation and a long cycle, which affects the batching accuracy.
PLC + Digital Transmitter + Industrial Computer
Characteristics:
- Data acquisition and processing tasks are performed by digital transmitters.
- The transmitter transmit the weight data to the PLC by the communication method.
- Computer does not participate in control.
Advantages:
- Digital acquisition and processing tasks are performed by digital transmitters.
- The batching control is completed by PLC, the system is very flexible.
Disadvantages:
- The transmitter transmit the weight data to the PLC by the communication way.
- The speed of communication affects the batching accuracy.
PLC + Batching Controller + Industrial Computer
Characteristics:
- The batching core is completed by the batching controller
- PLC is only responsible for production process control
- The computer does not participate in the control
Advantages:
- Uniform load distribution
- PLC does not need to perform numerical calculations
- High batching precision and good stability
Disadvantages:
- Poor flexibility
- Poor support for distributed systems
Computer + Board / Transmitter
Characteristics:
- Data acquisition and processing is performed by the board or transmitter.
- Ingredients control is controlled by computer.
- The production process is controlled by computer live PLC.
Advantages:
- After the board collects the data, it processes it on the spot.
- Ingredients control is done by computer, the system is very flexible.
Disadvantages:
- The biggest unstable factor lies in the computer’s operating system.
- Amplifiers must be used when using boards.
How Does Concrete Batching Plant Control System Work
Take LUTON “PLC + Batching Controller + Industrial Computer Control System” as an instance, let’s take a look at how does concrete batch plant control system work.
This type of concrete batch plant control system is consisted of industrial computer, PLC programmable logic controller, batching controller (batching instrument, load cell and other actuators) and so on.
The industrial computer is the upper computer, which sends production instructions to the PLC and batching controller (weighing instrument). PLC is the lower computer. After receiving the instructions of the industrial computer and the input signal of the batching controller, the PLC controls the actions of the solenoid valve and motor of the electric control system of the mixing station. The batching controller starts batching after receiving the command of the industrial computer.
During the working process of the concrete batching plant, the industrial computer collects，displays and stores the data of the batching controller, and collects the status signals of the PLC for the dynamic display of the production interface.
The industrial computer obtains the data of the operation status of the concrete batching plant in real time, and carry out the next production operation according to these feedback data.
During the entire production process, each part of the control system performs its duties. The industrial computer is responsible for production task management, data storage, and issuing production orders. PLC is responsible for production process control (motor and solenoid valve action), and the batching controller is responsible for weighing and batching.
