Based On Wifi Technology Design And Development Of Production Data Acquisition Terminal

WIFI technology meet the demand for mobile high-speed access to the Internet within a certain area, Relying on development trend of the WIFI technology as well as the mobile Internet, Take advantage of WIFI technology easy to use, low-cost networking, maintainability, for the data transmission needs of discrete manufacturing production data acquisition and release, developed a data transmission terminal use WIFI technology.The paper analyzes production data and its classification Firstly, production data are divided into three types of data of production, quality, equipment; The collection mode is divided into manual input and automatic acquisition. And detailed analysis of a selection of networking solutions; According to the design requirements, design the overall function of data transmission terminal; data transmission terminal is used by a variety of ways with the data in the production of PC management software acquisition process, and published for the user production information; As a link producers, production process the workshop management control of the transmission medium. According to the design of the function, design the hardware circuit, software module of the data transmission terminal; Achieve the design goal of data transmission terminal to transmit industrial production data through WIFI technology.Finally, according to the application requirements for data transmission terminal, Simulate the actual application environment, the establishment of a network environment as well as the preparation of the host computer testing software; Debugging the hardware circuit of data transmission terminals. Test data transmission terminal send and receive information, production data acquisition, the acquisition of the realization of the design features of the device data, serial gateway; Verify the successful application of the WIFI technology in production data collection terminal.
