Abstract
Aiming at the problems such as limited transmission distance of traditional temperature data, complex wiring and aging line, ZigBee wireless network is introduced into the temperature acquisition system of the intaglio printing machine oven, which makes the whole system easy to operate and simple, and greatly improves the transmission distance of temperature signal. The composition of the temperature monitoring system and the hardware circuit of the ZigBee master node are described, including DC 5 V power supply circuit and USB interface power supply circuit, the connection circuit between the RADIO frequency board and the backboard, to realize the construction of the network and the wireless reception of temperature data. To realize the construction of the network and wireless reception of temperature data. It combines ZigBee wireless communication technology to complete real-time transmission of multi-point temperature data, realize real-time LCD display of multi-point temperature data collected by DS18B20, and realize ZigBee networking function based on ZigBee protocol stack.
