Embodiment 1

[0021] Such as figure 1 As shown, the structural block diagram of the system includes the field layer, NB network layer, cloud server layer and mobile device layer, and the functions of each layer of the system are as follows:

[0022] The field layer is composed of intelligent terminal equipment (Ⅰ). Intelligent terminal equipment (I) includes surge protector SPD monitoring module (1), lightning warning module (2), terminal control module (3), MCU module (4) and NB-IOT wireless transmission module (5). The SPD monitoring module (1) is used to monitor the operating environment and operating status of SPDs at all levels in real time, and collect core information such as ambient temperature and humidity, surge current amplitude, polarity, time, and SPD working status; the lightning warning module (2) is used to It is used to predict the occurrence of lightning and upload an alarm; the terminal control module (3) is used for remote switching of special electrical equipment under...

Embodiment 2

[0027] Such as image 3 As shown, the above-mentioned NB-IOT-based substation intelligent lightning monitoring system work flow chart, the specific steps are as follows:

[0028] S01, collecting information: through the SPD monitoring module (1) in the intelligent terminal device (Ⅰ), perceive the operating environment and operating status of SPDs at all levels, and collect environmental temperature and humidity, surge current amplitude, polarity, time, and SPD working status and other core information; predict lightning occurrence information through the lightning warning module (2). After receiving the early warning information from the lightning early warning module (2), the alarm information is sent to the user immediately through SMS, APP push, etc.

[0029]S02, transmit information: transmit the information to the NB-IOT base station (II) through the NB-IOT transmission module (5) in the smart terminal device (I), and upload the information to the cloud server (III) thr...

Abstract

The invention discloses an intelligent lightning monitoring system based on NB-IOT. The system is characterized in that the operating environment, an operating status and surge core parameters of SPDsat all levels are collected by an SPD monitoring module; occurrence of lightning is predicted by a lightning warning module, and the alarm is uploaded; on and off of a power source of special electrical equipment can be remotely operated by a terminal control module, and old surge protectors with faults can be automatically replaced; data communication between an MCU module and other modules is performed; data is transmitted by an NB-IOT wireless transmission module to a cloud server; the NB-IOT network is created based on an NB-IOT base station; the cloud server is used for realizing data storage, calculation and analysis and control instruction issuing and transmitting the alarm and real-time monitoring data for mobile equipment. The system is advantaged in that the system is an intelligent lightning monitoring system which is based on the NB-IOT narrowband IoT technology and has properties of low power consumption, low cost, wide coverage and long distance, system design is reasonable, the intelligent degree is high, the application scope is wide, and the system is easy for realization.

Description

technical field [0001] The invention relates to an NB-IOT-based intelligent lightning monitoring system, which belongs to the technical field of lightning monitoring. Background technique [0002] In recent years, with the development of intelligent systems such as intelligent buildings, smart grids (smart substations), and intelligent communication base stations, there are more and more information-based electronic devices. Therefore, in order to ensure the normal operation of the equipment in the substation, a large number of surge protectors (SPD) are installed in the substation. SPD runs online for a long time, and its performance will gradually decline or even fail under the effects of lightning strikes and natural aging. At present, most of the substations and communication base stations are unattended, so the failed SPDs cannot be prevented or eliminated in time, which brings serious hidden dangers to the safe operation of the power distribution system. In order to ...
