Third party monitoring system of power distribution box

Abstract

The invention discloses a third party monitoring system of a power distribution box. The third party monitoring system comprises a central server group, a narrow-band internet of things base station and a control terminal, wherein the control terminal is used for acquiring information of the power distribution box and transmitting the information of the power distribution box to the central server group through the base station, and the central sever group is used for storing and processing the information of the power distribution box and transmitting an instruction to the control terminal through the narrow-band internet of things base station. The system employs an independent internet of things communication technology to communicate and does not cross an original communication system, an original arbitrary circuit structure is not adjusted, design and construction are performed strictly according to a non-intrusive principle, and influence on normal working of an original low-voltage integrated power distribution box is prevented; and the control terminal employs a LPWAN communication technology which is low in speed ratio, ultralow in power consumption and low in duty ratio and of which a start network covers and the maximum coverage of a single node can reach 10 kilometers, the applicability and the practicability of the system are improved, the control terminal can be arranged within a large range, and meanwhile, the electric consumption and communication cost are reduced.

Description

technical field [0001] The invention relates to a third-party monitoring system for a distribution box. Background technique [0002] The low-voltage integrated distribution box is mainly used for the control and distribution of electrical equipment, and to protect the overload, short circuit, and leakage of the line. Usually, the built-in communication unit and PLC unit realize remote control and intelligence. With the development of the city, the requirements for the reliability of the low-voltage integrated distribution box are getting higher and higher. In the existing technology, the monitoring system of the distribution box is not perfect, and the monitoring information is not comprehensive enough. At the same time, there is no compliance in the market. Distribution box monitoring equipment designed on the principle of non-intrusion generally adopts a non-independent monitoring system that intersects with the original communication system inside the distribution box.

With the development of the city, the requirements for the reliability of the low-voltage integrated distribution box are getting higher and higher. In the existing technology, the monitoring system of the distribution box is not perfect, and the monitoring information is not comprehensive enough. At the same time, there is no compliance in the market. Distribution box monitoring equipment designed on the principle of non-intrusion generally adopts a non-independent monitoring system that intersects with the original communication system inside the distribution box. Once the distribution box is powered off, the monitoring device will also stop running, and the non-independent monitoring system It will have a certain impact on the normal operation of the distribution box
