Problems solved by technology

From simple encoding and decoding strings to specific byte messages and then to strings with specific headers and tails, etc., the accuracy and security of data are gradually enhanced, but in terms of flexibility of use, prevention of packet loss, etc. There are still deficiencies in the problem, and it is worth further discussion and research
The existing technology for preventing data packet loss is very likely to ensure that each piece of data is not lost, but it cannot guarantee that the information in a single data is not lost or that wrong information is imported, and the complexity of parsing data is relatively high

Embodiment Construction

[0017] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0018] The present invention is illustrated by the communication control between the dispatching system and the AGV stacking truck. The dispatching system is used as the upper computer, and the palletizing truck is used as the lower computer. In order to realize the communication between the upper computer and the lower computer, the application design The format of the communication of the information transmission is more delicate, and according to the design of the format, functions such as verification in the information, control information, and data loss judgment are performed.

[0019] A communication method for scheduling control, the communication method is used to realize the data communication between the upper computer and the lower computer; the upper computer is used to send the...

Abstract

The invention discloses a communication method for scheduling control. The communication method is used for realizing data communication between an upper computer and a lower computer. The upper computer is used for sending published information to the lower computer, and the lower computer is used for sending feedback information to the upper computer, the published information and the feedback information both adopt a structural body form with verification information to send information. The method has the advantages that communication is reliable and safe, packet loss can be prevented, wrong control can be prevented when wrong information is imported, and whether data packet loss occurs or not can be verified; instant stop of the lower computer and efficient use of task information areeffectively controlled. According to the set sign check bit, a reconnection mechanism is combined to ensure that reconnection does not miss the reception of effective tasks during operation.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a communication method for scheduling control. Background technique [0002] In the prior art, wireless communication control is used in all aspects of industry. The communication and control between the upper computer and the lower computer are realized through wireless communication. In the field of wireless data transmission, there has always been how to ensure the integrity and real-time performance of data. The problem, and what kind of protocol, that is, the arrangement of data, can quickly realize the correct transmission and analysis of information, which has been researched. In the application of AGV control, this problem is more prominent, which involves the control safety and control accuracy of the vehicle. From simple encoding and decoding strings to specific byte messages and then to strings with specific headers and tails, etc., the accuracy and security of d...
