Wireless Data Communication Method Applied to Industrial Inspection

Abstract

The present invention discloses a wireless data communication method used for industrial detection. The method comprises that a client computer initiates a handshake connection to a server at the beginning of data communication, the client computer transmits a connection request data packet, and the server replies a connection confirmation data packet; the client computer transmits data to the server after the client computer receives the connection confirmation data packet, and during data transmission, the client computer adopts repeated transmission, and the server adopts redundancy confirmation; and after the data communication is completed, the server initiates handshake disconnection to the client computer, the server transmits the data confirmation packet for showing receiving all the data, the client computer transmits connection disconnection data packet to the server after the client computer receives the data confirmation packet, and after the server receives the connection disconnection data packet, the data communication is ended. With the method of the present invention, the defects of the traditional data communication in the industrial production site can be overcome, the accurate and reliable data transmission can be ensured, the industrial production efficiency is improved, and the correct application of the test data is ensured.

Description

technical field [0001] The invention relates to a wireless data communication method applied to industrial detection. Background technique [0002] With the development of science and technology, data transmission networks, especially wireless networks, are widely used. Therefore, data transmission through wireless networks in industrial testing is the first choice for most testing equipment. However, due to the harsh environment of most industrial production sites, there are various interferences such as magnetic fields and electric fields around, and the stability of wireless signals is poor, which seriously affects the accurate and reliable transmission of data. Once the data transmission is wrong, the previous detection work needs to be repeated. , or affect the later data analysis and processing, which reduces the production efficiency and affects the correct application of the detection data. At the same time, the traditional TCP / IP-based data communication is based o...

However, due to the harsh environment of most industrial production sites, there are various interferences such as magnetic fields and electric fields around, and the stability of wireless signals is poor, which seriously affects the accurate and reliable transmission of data. Once the data transmission is wrong, the previous detection work needs to be repeated. , or affect the later data analysis and processing, reducing production efficiency and affecting the correct application of detection data

At the same time, the traditional TCP / IP-based data communication is based on wired data transmission, and its complex handshake and interaction mechanism are prone to communication interruption or long-term delay, especially in some embedded devices, due to the imperfect implementation of the protocol stack , so that the data communication is not only long but also very unstable, which limits the application of data transmission in industrial production sites
