本文阐述了利用短距无线直接将温枪的热电偶信号发送到接收端进行应用的方法,基于TI的内部集成51内核的CC2430 RF SOC芯片,将经过A-D转换的S热电偶信号进行数字滤波、温度补偿处理后进行无线发送,并在接收机端将信号转换成RS485信号、4-20mA电流信号进行显示或控制,并可多点测量ZIGBEE组网。
This paper describes a method of using the short-range wireless to send the thermocouple signal of the warm gun directly to the receiving end. Based on TI’s internal integrated CC2430 RF SOC chip with 51 cores, the AD-converted S thermocouple signal is digitally filtered, Temperature compensation after the wireless transmission, and in the receiver side of the signal into RS485 signal, 4-20mA current signal display or control, and multi-point measurement ZIGBEE networking.
