基于GPS和LabVIEW的电子警察时间校验方法研究
Study of Electronic Police' s Time Calibration Based on GPS and LabVIEW
摘要
Abstract
The accuracy and synchronicity of time are the important performance indicators of electronic police , but there are still few corresponding detection methods. Aiming at the electronic police' s time calibration problem, standard clock was designed based on GPS and LabVIEW in this paper. The Interruption mode of serial communication was introduced in to achieve the communication between GPS-OEM and PC. And the program was written in LabVIEW with the help of MSCOMM. It was so simple that the real time data reception was ensured. And then the precision of the clock was improved. Finally DataSocket was brought in to achieve the batch time calibration online. The actual test shows that the system has a strong practicability.关键词
