摘要:
时间的准确性和同步性是电子警察系统的重要性能指标,但是目前仍鲜有相应的检测方法.笔者针对电子警察时间校验问题,设计了基于GPS和LabVIEW的标准时钟.在LabVIEW开发环境下借助MSCOMM控件实现了GPS-OEM与PC机之间中断方式的串口通信.程序实现简单,保证了数据接收的实时性,进而提高了时钟精度.最终利用DataSocket技术实现了在线批量时间校验.经过实际测试表明本系统具有很强的实用性.
Abstract:
The accuracy and synchronicity of time are the important performanee indicators of electronie po-lice, but there are still few corresponding detection methods. Aiming at the electronic police’s time calibrationproblem, standard clock was designed based on GPS and LabVlEW in this paper. The Interruption mode ofserial communication was introduced in to achieve the communication between GPS-OEM and PC, And theprogram was written in LabVlEW with the help of MSCOMM. It was so simple that the real time data receptionwas ensured. And then the precision of the clock was improved. Finally DataSocket was brought in to achievethe batch time calibration online. The actual test shows that the system has a strong practicability.
