More Information
Summary:The invention discloses an intelligent electronic scale based on ZigBee and RFID. The intelligent electronic scale is characterized in that a main system comprises a ZigBee terminal node and a main node, the main node is connected with a PC terminal via a serial port, and the terminal node is connected to the main node via a star-shaped network; the terminal node comprises a CC2530 controller module, an AS1117 power module, a TFT liquid crystal display module, a PS2 keyboard input module, an RFID module, and a pressure sensor module; the AS1117 module supplies power to the CC2530 controller module; a PS2 keyboard is used as a man-machine interaction part to provide commodity information external input; the RFID module is connected with the CC2530 controller module via a SPI interface to send the read commodity information to the controller; a weighing module can detect the weight of a commodity; and the LCD module displays the transaction information.
