Concrete Batch Control Systems

Concrete batching plant is a kind of construction machinery that is widely used in the construction industry.
Concrete batch control systems usually adopt a control mode of relay loops and smart meters.
In the concrete formula of the actual production process, the supply of each ingredient and each link，all the time control needs to be realized by the operator through the observation of the instrument.
This kind of control system with low degree of automation and poor reliability is increasingly unable to meet the needs of the construction industry.

Because the working environment of the concrete mixing plant is very harsh, the relay control system of the traditional concrete mixing plant is prone to failure in the actual production process, the relay circuit is very complicated, and the equipment is also very difficult to repair and maintain.

For the HZS60 concrete mixing plant, the design framework of using the upper computer and the lower computer in the automatic control system of the concrete mixing plant is proposed.
Using this control system, the operator can accurately control and master the entire actual production process through the operation of the host computer.
At the same time, by calling various reports of the host computer, it is convenient to count and query the production volume and material consumption within a certain period of time. Information such as the situation and customer conditions. The use of this design has greatly improved the production automation of the mixing plant and the safety and reliability of the work.

1. HZS60 concrete mixing plant process requirements

The control system of the HZS60 concrete batching plant is specifically designed for the maximum production mode of the 60 concrete mixing plant.
It uses sand silo, coarse stone silo, fine stone silo, cement silo, powder additive silo, aggregate scale, and powder scale，external additive scale, water scale, a total of 7 silos and 4 scales.

2. Software Design of monitoring System of HZS60 Mixing Station

The host computer of the system has the characteristics of dustproof and shockproof, which can fully guarantee the stable operation of the system in a harsh working environment.
The host computer monitoring software adopts MCGS (monitor and control generated system).
MCGS is a set of configuration software used to quickly construct and generate a computer monitoring system. The system uses MCGS to realize the collection and processing of field data, and achieves good results in various ways such as animation display, alarm processing, process control and report output.

3. Animation configuration

In order to understand the actual production status of concrete batch control systems in real time, this system makes full use of the animation configuration function of MCGS, through the animation of the host computer and the actual production process, so that the operator can accurately grasp the actual working status of the site.
Using the existing graphic elements in the MCGS library, the main structure of the HZS60 mixing station is simulated through a variety of combinations, and the corresponding variables are defined for the graphic elements in the real-time database and then connected with the DI signal of the lower computer, so as to achieve In order to synchronize the animation with actual production, the monitoring function of the host computer is also realized.

A concrete mixing plant is indispensable in infrastructure construction, it is composed of multiple systems.
Concrete batch control systems are one of the most important systems.
In the production of concrete, the weighing accuracy of the ingredients, the construction ratio of the ingredients, the moisture content of the raw materials and the water supply directly affect the quality of the concrete. In addition, in the control system, the connection with the hardware equipment and the formulation data Storage and management of raw material registration, warehouse management, operator login records, product transportation records, etc. during the production process will also directly affect the production efficiency of the enterprise.

At present, most domestic concrete batch control systems still have disadvantages such as low technical content, low degree of self-control, and low degree of standardization.
The connection between traditional concrete batch control systems and hardware devices requires complicated settings, and the software code needs to be modified and debugged separately for different devices. The maintenance work is complicated, which brings great difficulties to manufacturers.

The following three concrete batching plants also use concrete batch control systems, if you interested in, pls chick the photo to learn more.
