Module combined type batching control system

Abstract

The invention discloses a module combined type batching control system which comprises a power supply communication board, a CPU (Central Processing Unit) main control board, an analog quantity input board, a switching value input board, a switching value output board, a wireless communication board and an aluminum alloy shell, the power supply communication board, the CPU main control board, the analog quantity input board, the switching value input board, the switching value output board and the wireless communication board are integrated in an aluminum alloy shell, and all modules in the aluminum alloy shell adopt a double-row pin insertion combination mode. Compared with a one-master and multi-slave control mode, the control system has the advantages that the acquisition delay time from the input signal acquisition module to the CPU main control board is shortened, the rate of issuing data to each execution module by the CPU main control board is increased, the real-time efficiency of the whole control system is improved, and the control system is suitable for popularization and application. The comprehensive response speed of equipment is improved.

Description

technical field [0001] The invention relates to the technical field of weighing and batching, in particular to a modular combined batching control system. Background technique [0002] In the field of weighing and batching, due to the different numbers of switching sensors, analog sensors, and actuators installed on site mechanical equipment and the different data communication methods required by customers, it is necessary to screen and match according to the actual situation on site to meet the functional requirements. Batch control system. This method will easily lead to unnecessary troubles such as long selection time, high cost of technical selection, delay in construction period, wrong selection and so on. In other distributed control systems, master-slave devices often need to use 485 and CAN bus to communicate, while 485 and CAN bus need to use cables to connect master-slave devices. The length and quality of cables will ensure the accuracy of data transmission. an...

Problems solved by technology

[0003] The purpose of the present invention is to provide a module combined batching control system, which can improve the comprehensive response speed of the equipment: compared with the control mode of one master and multiple slaves, this control system reduces the acquisition delay from the input signal acquisition module to the CPU main control board time, which improves the rate at which the CPU main control board sends data to each execution module, improves the real-time efficiency of the entire control system, improves the comprehensive response speed of the equipment, and solves the problem of screening and matching the required batching control system according to the actual situation on site. , lead to long selection time, high cost of technology selection, delay in construction period, wrong selection and other problems; solve other distributed control systems, because the master and slave equipment often need to use 485, CAN bus to achieve communication, while 485, CAN The bus needs to use cables to connect the master and slave devices. The length and quality of the cables will affect the accuracy and timeliness of the transmitted data.
