| 摘 要： | 利用单片机SST89C58实现了环形线圈车辆检测器的设计。由MM74HC4046M构成的锁相环电路与环形检测线圈一起构成LC震荡电路,并将LC震荡波形转换为单片机可使用的方波;由XC9536XL-7VQ44C构成的EPLD电路对各路检测信号进行循环检测,并送入SST89C58单片机进行处理,处理后的信息由MAX488EESA构成串口输出。

| Abstract: | The loop-coil vehicle detector is designed with SST89C58 microprocessor.The phase-locked loop circuit consisting of MM74HC4046M CMOS chip and the loop-coil detector form the LC vibration circuit,that converts the LC vibration wave into square waves for microprocessor processing.The EPLD circuit consisting of XC9536XL-7VQ44C,detects all the input channels circularly.The SST89C58 microprocessor processes the signals sent by EPLD circuit.The data is send out by the serial port which consists of MAX488EESA. |
