Embodiment Construction

[0013] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0014] In this specific implementation mode, the following protocol is used for communication between the AGV car and the AGV car, and between the AGV car and other equipment in the system. This protocol is a communication layer protocol based on UDP and runs on the AGV car to realize remote monitoring. communication protocol. A two-way communication protocol designed according to the principle of multi-computer communication, including a communication layer and a protocol layer. The communication layer is used for verification, loss prevention, multi-machine judgment, etc. The protocol layer is used to analyze the content of the data packet, and the structure of its communication data is as follows: figure 1 shown.

[0015] As shown in Table 1, for the communication frame of this set of protocols, the protocol revision frame header is 0xff, 0x01 frame tail...

Abstract

The invention discloses an AGV (automatic guided vehicle) communication method based on a UDP (user datagram protocol), belongs to the technical field of AGV communication and aims at providing the AGV communication method based on the UDP with the advantages that the multi-machine communication is realized; the data transmission is reliable; the expansion and the maintenance are easy. According to the method, the protocol based on UDP is used between the AGVs and between the AGV and other equipment of the system for communication; the protocol based on the UDP comprises a protocol layer and a communication layer; the protocol layer includes a sending sequence number and a receiving sequence number; the data received and sent by the communication layer is in the communication range of the protocol layer. The communication protocol of the method is oriented to the non-connection; the multi-machine communication and the data packet loss prevention are realized; the data is reliably transmitted; the transmission efficiency is high; the expansion addition of communication nodes is simple and flexible; the maintenance is easy; through the improvement of the communication method, the dispatching control capability of the AGV system is improved.

Description

technical field [0001] The invention specifically relates to a UDP-based AGV car communication method, and belongs to the technical field of AGV car communication. Background technique [0002] With the advancement of modern informatization, the rapid development of the Internet of Things and the technical background of Industry 4.0, the requirements for communication between industrial equipment and between equipment and the Internet are higher. AGV (Automated Guided Vehicle) is a part of the overall Industry 4.0 layout, and stable communication between AGV cars and between AGV cars and other parts of industrial equipment is becoming more and more important. [0003] The existing industrial wireless communication is mainly the Modbus communication protocol in the industrial Ethernet. ModBus is an industrial communication system, mainly used in industrial field bus protocol. This protocol embeds the Modbus frame into the TCP frame, and combines Modbus with Ethernet and TCP...
