OPC server suitable for AGV operating in elevator hoistway, control system and control method

Abstract

The invention provides an OPC server suitable for an AGV operating in an elevator hoistway, a control system and a control method. The OPC server comprises an AGV connecting port, an elevator connecting port and a processing device, wherein the processing device is used for executing the following instructions of receiving AGV operation information through the AGV connecting port and processing the information according to an OPC protocol to facilitate obtaining by an elevator, and receiving elevator operation information through the elevator connecting port and processing the information according to the OPC protocol to facilitate obtaining by the AGV. The control system comprises the AGV, the elevator, a PLC (programmable logic controller), a central control computer, an AGV dispatchingsystem and the OPC server, wherein the PLC is in communication connection with the elevator and is used for controlling the action of the elevator, the OPC server and the AGV dispatching system are established on the central control computer, the central control computer communicates with the PLC through the OPC server, and the AGV dispatching system is used for the dispatching work of the AGV. Through the OPC server, the AGV and the elevator can directly communicate with each other, a control module and a wireless communication module are prevented from being additionally arranged, and interference can be prevented.

Description

technical field [0001] The invention relates to the technical field of AGV dispatching systems, and mainly relates to an OPC server, a control system and a control method suitable for AGVs running in elevator rooms. Background technique [0002] In the context of Industry 4.0, AGVs are increasingly used in smart logistics factories. Laser navigation AGV carries the handling tasks in various scenarios, and has the characteristics of high positioning accuracy, strong load capacity, and high transportation efficiency. [0003] In general, the laser navigation AGV is heavy and has a high load-bearing capacity for the floors of the factory. In most scenarios, the AGV only works on the ground floor. Realization can only be carried by manual forklifts, which is not conducive to the development of smart factories. With the development of laser navigation AGV, AGV began to be applied to more and more scenarios, from the initial single area to multi-area, single floor to multi-floor...

AI Technical Summary

Problems solved by technology

In the past, if the AGV directly communicates with the elevator, it is necessary to install a wireless communication module on each AGV, and install a control module and a wireless communication module on each elevator door. However, when the number of AGVs is large, other When the number of equipment reaches a certain level, interference will occur, resulting in unstable system control, and the system layer cannot obtain the communication between the AGV and the elevator.
