Detailed description of the concrete mixing plant control system

 The control system dominates the entire concrete mixing plant.It can control a few separate batch line at the same time, the mixing station to implement long-range centralized control operation, its configuration is divided into three grades, the current market is more common is a centralized control system, semi-automatic configuration, but also fully automatic configuration of. In general, semi-automatic configuration for the engineering station, common models are HZS25, HZS35, HZS50, HZS75, etc., the configuration level slightly lower than the fully configured business mixed statiion.Detailed description of the concrete mixing plant control system:

1, distributed control system. This type of control is widely used in the early concrete batching plant design. The core of the control system is the programmable controller, the upper level computer only as the management report printing, the computer function and the function is not very obvious. With the widespread use of commercial concrete mixing plant, the function of the concrete mixing plant is more and more complex, this control form of application is very difficult.

2, centralized semi-automatic control system. This form of control will be computer control and management functions focused on a computer, the task is relatively heavy, and the production process of the report data statistics can not be synchronized, can not always statistical data, measurement aspects of interference by human factors too much. For example: the preparation of measurement control procedures, signal amplifiers and A / D board accuracy, will affect the measurement accuracy.

3, centralized automatic control. This form is to solve the measurement of human factors interference. The use of a dedicated batch plant of control instruments, and the production control and management functions are divided into two computers, do not interfere with each other, production control and report statistics simultaneously, and management of the computer can also be used as a production backup machine, The computer's network interface.
