Design of the Production Data _________ __ Acquisition Terminal Based On WI-FI
Abstract With the development of manufacturing technology, the requirement for information management becomes higher and higher. This also puts forward new requirements for the production data acquisition part of the manufacturing execution system. The portable data acquisition terminal in the workshop will get a great development for its compact and convenience. With the external device which can automatically collect data, and the WIFI module which has the access to Internet to transmit data to the PC, they combine into an integrated data acquisition system. This paper first introduces the research background and the advanced production system. Then puts forward the idea of portable production data acquisition terminal, combining with the domestic situation of the production workshop. By using the Supervisory Control and Data Acquisition software develop the program which is suitable for industrial production process, combining with the circuit board of the microprocessor, they complete the data acquisition and transmission.
