Distributed control system and control method for conveyer

Abstract

The invention discloses a distributed control system and control method for a conveyer. The distributed control system for a conveyer includes a data interface terminal, a data transponder and cell controllers, wherein the data interface terminal monitors the state of the conveyer and logic control of conveying service; the data transponder is connected with the data interface terminal and the cell controllers through Ethernet and CAN network respectively, and perform Ethernet-CAN format conversion for the received data information; the cell controllers are arranged on conveyer cells; each cell controller is provided with an photoelectric interface, a motor interface and a CAN bus interface; the upstream and downstream cell controllers are connected, and the related conveying state can be acquired through the CAN network; and the conveying logic is executed and conveying of the articles supported on the conveyer cells are controlled. The distributed control system and control method for a conveyer utilize distributed control, arrange the cell controllers, the sensors, the motor and the conveyer cells together, and utilize complete distributed arrangement, thus greatly saving the cable cost and the wiring cost, and being convenient for maintenance and overhauling.

Description

technical field [0001] The invention relates to the technical field of logistics automation, in particular to a conveyor distributed control system and a control method. Background technique [0002] At present, the control system widely used in the logistics automation industry is mainly the PLC distributed control system for system integration. All control components are centrally arranged in the PLC control cabinet, and then the photoelectric signals of each conveyor unit node are led to the switch input module of the PLC cabinet through the cable, and after being scanned by the PLC controller master station, the relevant logic is executed, and then the switch is controlled. Quantity output module, and then lead to the conveyor through the cable to control the operation of the motor to transport the items. [0003] The main disadvantages of adopting PLC distributed control system are as follows: [0004] 1. Since the PLC modules are all arranged in the PLC cabinet, all ...
