Embodiment 8

[0100]Embodiment 8 is a mobile terminal, which includes a communication module, a memory, a processor, and a computer program stored in the memory and running on the processor. The processor and the communication module are connected. The module is connected to the edge computing module 2 in the IOT sensing and monitoring system, and is used to receive the early warning information sent by the IOT sensing and monitoring system when the preliminary judgment result is that there is a latent defect, and can also be used to access the cloud State historical data on the server. The operation and maintenance staff are equipped with mobile terminals, which are easy to use and can receive early warning information anytime and anywhere, which greatly improves the efficiency of notifications. They can query the status history data on the cloud server anytime and anywhere, and the interactive experience is good. The IoT sensing and monitoring system in this embodiment is as described in Embodi...

Embodiment 9

[0101]Embodiment 9 is a cloud server, connected to the IoT sensing and monitoring system, and used to receive and store the early warning information sent by the IoT sensing and monitoring system when the preliminary judgment result is that there is a latent defect. When receiving a query request from the edge computing module 2 in the IoT sensing and monitoring system to query the status history data of the power equipment stored in the cloud server, it sends the status history data of the power equipment to the object. Edge computing module 2 in the joint sensing monitoring system. The cloud server provides one more backup method for the state history data of the power equipment, and can communicate with the edge computing module 2 in the IoT sensing monitoring system in real time, which improves the efficiency of latent defect investigation. The IoT sensing monitoring system in this embodiment is as described in Embodiments 1 to 7.

Abstract

The invention is applicable to the technical field of power equipment monitoring, and provides an Internet of Things sensing and monitoring system and monitoring and early warning method, a mobile terminal and a cloud server, the system comprises a plurality of Internet of Things sensing and monitoring devices, and each Internet of Things sensing and monitoring device comprises a group of front-end sensors and edge calculation modules which are arranged in a one-to-one correspondence manner; the plurality of Internet of Things sensing and monitoring devices are respectively arranged at a plurality of monitoring positions of the power equipment so as to monitor latent defects at different positions of the power equipment through the front-end sensors, and each edge calculation module collects output result signals of the corresponding front-end sensor; and when the output result signal is an abnormal signal, whether the abnormal signal is falsely triggered or not is judged according tothe output result signal of the front-end sensor at the adjacent monitoring position so as to obtain a preliminary judgment result. The edge calculation module integrates the output result signals ofthe front-end sensors at the adjacent monitoring positions to jointly judge whether the abnormal signals are mistakenly triggered or not, and the accuracy of early warning can be improved.

Description

Technical field[0001]The invention belongs to the technical field of power equipment monitoring, and in particular relates to an IoT sensing monitoring system, a monitoring and early warning method, a mobile terminal and a cloud server.Background technique[0002]On-line monitoring of power equipment is an effective way to discover early latent defects of equipment, but the current online monitoring technology still misses and false alarms in practical applications. Take two UHV stations in Hebei as an example. In the daily operation process, several UHF online monitoring system alarms occurred, and no problems were found in the equipment retest on site, and the alarm signal disappeared after a period of time. For another example, in September 2018, a 1000kV UHV station sent power to the No. 4 main transformer according to the dispatching instruction, and the internal discharge occurred less than 4 minutes after the T052 switch was turned to hot standby, which caused the adjacent swit...
