远程视频监控系统中电源的检测

提出了一种结合多种监控方式的远程视频监控系统并着重介绍了其电源检测模块。该模块以电能质量管理芯片DS2438为核心实现对太阳能蓄电池电压、电流、温度的直接测量,并结合实验测得的电压-电量对应曲线实现对剩余电量的间接估计,实测证明该模块的测量误差在允许范围内,可以较为精确地反映蓄电池的状态,提高远程监控系统运行的可靠性。该系统可应用于野外环境下电力输电线路的安全保障环节,保障电力系统的安全运行。

Power detection for remote video monitoring system

This paper proposes a kind of remote video monitoring system with collection of various monitoring methods and focuses on introducing the power detection module.The voltage,current,and temperature of solar battery can be directly measured by power quality management chip DS2438,and combining with the correspondence between voltage and capacity of battery obtained from the experiment,the residual battery capacity can be indirectly estimated.The test results show that the measurement error is within the allowable range,the module can make an accurate reflection of the state of the solar battery,thus improve the reliability of the system.This system can be applied to the field of electric power transmission line security which is to ensure the safe operation of the electric power system.
