基于ZigBee的临近带电体安全距离报警装置研制

Design and Implementation of Distance Measurement Device Adjoining High Voltage Potential Based on ZigBee

电力系统施工时,经常需要进行临近电位的施工,因此,为了防止安全事故发生,施工人员与带电体的距离必须在安全距离之外。现有的安全距离测距大多是依靠经验的视力测量或者拉线测量,容易出现误测,存在安全隐患。文章针对临近电位作业安全距离测量难问题,基于超声波测距技术和ZigBee无线网络技术,设计了一套临近电位的带电体测距报警装置,能够准确测量出施工人员和带电体的距离。通过声光报警能及时地提醒施工人员,对于保障临近电位作业的人身安全有重要意义。

When construcing electric power system,it is often necessary to carry out the construction of near potential. Therefore,in order to prevent safety accidents,construction personnel and the distance from the charged body must be at a safe distance.The safety distance measurement of existing mostly rely on the experience of vision measurement or cable measurement,prone to measurement errors,there are security risks. Aiming at the distance measurement problem of near potential,this paper designs an alarm device can accurately measure the construction personnel and the charged body distance,which is based on the ultrasonic ranging technology and ZigBee wireless network technology. Through sound and light alarm,the construction personnel is reminded. The alarm device has important significance for the protection of near potential operation personal safety.
