Real-time data acquisition system of wheat processing factory

The invention discloses a real-time data acquisition system of a wheat processing factory. Data acquisition work can be carried out on wheat bins, flour bins, equipment and energy consumption and metering units of the wheat processing factory by the real-time data acquisition system, and acquired real-time data can be transmitted into a database server of a data acquisition processing center. Wheat bin and flour bin data acquisition portions comprise temperature, humidity, bin level, weighing and flow wireless sensing nodes, Zigbee terminals and a Zigbee coordinator; PLC (programmable logic controllers) are used as controllers of equipment and energy consumption data acquisition portions. The real-time data acquisition system has the advantages that the relevant data are acquired by temperature, pressure and counting sensor modules and rotational speed and current detecting modules inside the equipment and are transmitted into databases of the server via buses; data portions of the metering unit are acquired by wagon balances and are stored in local databases, and real-time data in the local databases are further transmitted into the server; video monitoring can be carried out on production lines and important places, and accordingly the equipment and the data of various production links can be acquired and analyzed in real time.
