Site production data acquisition method based on wireless network

The invention provides a site production data acquisition method based on a wireless network, which comprises the following steps of: building a site production data acquisition system, and establishing a plan standing book library table on an ERP (Enterprise Resource Planning) server, wherein the attributes of the plan standing book library table comprise batch number, process name, material code, card number, job number, equipment ID, start time, end time, reference time and preparation end; establishing the corresponding relationship between the RFID (Radio Frequency Identification Device)card number and the processing task batch number on a client by using a card issuing device; swiping the RFID card on the data terminal corresponding to the equipment when the processing task represented by the RFID card is started and ended on the equipment on the production site and the job number of a processor needs to be input; and activating the storage process to store corresponding data in the plan standing book library table when the data terminal swipes the RFID card or the button is pressed. Therefore, quick feedback of the production process is realized.
