| 摘 要： | 为了监控大电流磁体电源的温度变化,采用微处理器PIC18F248进行实时监控。首先设计传感器DS18B20的调理电路,通过添加共模抑制线圈提高系统的抗干扰能力,然后利用CAN总线完成多路多点的数据采集,最后采用LabVIEW驱动CAN接口卡并设计系统接收界面。

| Abstract: | In order to monitor the temperature of the power supply for the big current magnet,the main processor PIC18F248 was used to monitor in real-time.Firstly adjust circuit for sensors DS18B20 was designed,and common-mode coil was added to decrease noise.Then the transmission of the multi-channel and multiple point temperature was realized through CAN-bus.Finally using LabVIEW to motive CAN card and design surface. |
