Embodiment Construction

[0023] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0024] Such as figure 1 As shown, an NBIoT-based cable fault online temperature monitoring system includes a terminal master node, a network communication architecture and a central control server. The terminal master node is wirelessly connected to the central control server through the network communication architecture;

[0025] Such as figure 2 As shown, the main node of the terminal includes a fault acquisition module, an MCU and a terminal communication module. The fault acquisition module includes a thermal imager and a temperature sensor. The thermal imager is used for temperature monitoring of the high-voltage section of the cable, and the temperatu...

Abstract

The invention discloses an online cable fault temperature monitoring system based on NBIoT. The online cable fault temperature monitoring system comprises a terminal main node, a network communicationarchitecture and a central control server. The terminal main node comprises a fault acquisition module, an MCU and a terminal communication module. The network communication architecture is an NB-IoTnetwork architecture; the NB-IoT network architecture comprises an NB-IoT terminal, an E-UTRAN base station, a home subscriber server, a mobile management entity, a service gateway, a packet data gateway, a service capability opening unit, a third-party service capability server and a third-party application server. The central control server comprises a service server and a double-screen monitoring device. According to the NBIoT-based online cable fault temperature monitoring system, on-line temperature monitoring of cable faults and remote transmission of detection data are realized, the monitoring strength of coal mine enterprises on underground cables is improved, and the accuracy of coal cable fault monitoring data is improved through multi-information fusion.

Description

technical field [0001] The invention relates to the technical field of power grid monitoring, in particular to an NBIoT-based online temperature monitoring system for cable faults. Background technique [0002] With the continuous development of my country's economy and the continuous expansion of urban construction, the electricity load is also increasing. At present, the proportion of power cables used in my country's power transmission and distribution system continues to increase. Cross-linked polyethylene (cross-linkedpolyethylene XLPE) cables have the advantages of good insulation performance, good thermal and mechanical properties, and high power supply reliability. In the transmission lines and distribution networks of various voltage levels, and continue to develop into high voltage and ultra high voltage fields. [0003] The research on the on-line temperature monitoring technology of power cable insulation in our country is also carried out relatively early, but...
