Electronic Control System of Commercial Concrete Mixing Plant

Commercial concrete mixing plant electronic control system has a variety of types, the following three types are main control systems.
(1) Commercial concrete mixing plant distributed microcomputer control: This form of control widely used in concrete mixing plant design in the early days. The core of the control system is programmable controllers, level on your computer as part of the management report to print only, the computer's function and role is not very clear. With the wide application of ready mixed concrete, the increasingly complex requirements of concrete mixing plant, application of this control form is very difficult.
（2）Commercial concrete mixing plant centralized microcomputer control: this control model put computer control and management functions focused on one computer, the task is heavy, and the reporting information statistics cannot be synchronized in the production process, not statistical data at any time, measurement is interfered with human factors too much. For example: the formation of measure control procedural, precision of the signal amplifier and a/d converter card will affect the measurement accuracy.
(3) Centralized dual-microprocessor control of commercial concrete mixing plant: this form solves the measurement of anthropogenic interference. Using special burdening control instrument, and the production control and management functions at two computers, they are not interfering each other, the production control and report forms statistics of commercial concrete mixing plant can be produced at the same time, and managed computers can be as a backup machine, provided the network interface with the above level computer.
