Abstract

The invention relates to the electric safety field and provides a power supply loop monitoring device and system, solving the problem that the monitoring of loops is not accurate and has high cost. The system comprises data acquisition nodes and a data processing device, wherein the data acquisition nodes are arranged on each power supply loop or power supply sub-loop respectively to independently control each power supply loop or power supply sub-loop; the data acquisition nodes are communicated with a data processing unit to send the data of the data acquisition nodes to the data processing unit and receive the control instructions of the data processing unit for controlling the power supply loops or power supply sub-loops; and the data processing device performs statistical analysis to the data collected by the data acquisition nodes, sends the result of statistical analysis to a remote device and obtains the control instructions of the remote device. The embodiment of the invention combines with the networked centralized control management to ensure that the power supply line becomes safer and more reliable and the unnecessary power failure or fire is avoided.

Description

technical field [0001] The invention relates to the field of electrical safety, in particular to a power supply circuit monitoring device and system. Background technique [0002] At present, there is no mature real-time power consumption monitoring system in use at home and abroad, which itself is the main content of the low-voltage power consumption side of the smart grid that needs to be invested in and constructed. In the past, the main means of energy consumption monitoring was to obtain the active energy consumption recorded by the electric energy meter for a period of time (often in units of months). Obviously, this method of obtaining energy consumption by reading the electric energy meter The way of data has a series of shortcomings such as poor real-time performance and high cost. [0003] The "electricity sub-item metering system" that has begun to appear at present uses a large number of installed electric energy meters, and remotely reads electricity consumptio...
