摘要
为了解决传统漏泄电缆检测系统的应用局限性及低效性,设计了基于片上可编程系统的漏泄电缆自动检测系统。根据漏泄电缆检测的功能需求,该系统利用PSoC4实现运动控制与数据采集,通过双无线射频芯片完成磁区通信。然后,利用硬件对测距脉冲计数弥补软件的不足。最后,通过上位机软件实现漏泄电缆远程自动检测流程。实验数据表明,2.4 GHz通信频段下,通信速率达到2 Mbit/s,通信误码率小于2%,并且150 m内系统测距误差小于0.5%。满足漏泄电缆自动检测系统的低成本、高效及精度高等要求。
In order to solve the problem of limitation and low efficiency in traditional leaky cable detection system , an automatic leaky cable detection system based on PSoC was introduced .First, based on requirements of detection system, PSoC was used to achieve data collection and motion control.Then, around hardware design and software process commenced the implementation of automatic test scheme .Finally, client PC software is used to complete remote automatic test.The experimental data show that communication rate can reach 2 Mbit/s through 2.4 GHz communication link, and bit error rate less than 2%.The deviation of instance accuracy is below 0.5%.These vital characters basically meet requirements of system, such as stable, efficient and precision.
