Description

Technical Field

[0001] This utility model relates to the field of power grid fault monitoring technology, specifically a wireless monitoring system for power grid faults in underground space electromechanical systems. Background Technology

[0002] The underground environment is complex, especially in mine tunnels where the conditions are damp and harsh, making electromechanical systems prone to failure. Existing electromechanical systems often experience communication breakdowns and system malfunctions when power or network nodes fail. Fault information cannot be transmitted due to communication barriers, hindering repairs and potentially leading to system-wide paralysis. Currently, underground fault location requires manual on-site inspection, and some complex issues necessitate prolonged underground stays or multiple trips, which is dangerous, time-consuming, and labor-intensive. To address the difficulty and slowness of locating electromechanical system faults in underground spaces, a fault monitoring system capable of monitoring the operational status of electromechanical systems and accurately locating power grid faults is needed.

[0003] Currently, the monitoring and early warning of faults in underground space electromechanical systems is a completely new concept, and there are no mature fault monitoring systems for underground space electromechanical systems on the market.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a wireless monitoring system for power grid faults in underground space electromechanical systems, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a wireless monitoring system for power grid faults in underground space electromechanical systems, in order to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A wireless monitoring system for power grid faults in an underground space electromechanical system includes remote fault monitoring, comprising a power fault monitoring terminal, a network fault monitoring terminal, a fault monitoring system control host, and a fault monitoring and determination system. The power fault monitoring terminal includes an antenna, a wireless transceiver, a 220V voltage monitoring point, a 24V voltage monitoring point, an RS485 backup communication point, and a power input point. The network fault monitoring terminal includes an antenna, a wireless transceiver, a monitoring network port, a 220V voltage monitoring point, an RS485 backup communication point, and a power input point. The system also includes a fault monitoring relay gateway, which includes a communication gateway comprising an antenna, a wireless transceiver, and an RS485 backup communication point. The power fault monitoring terminal, the network fault monitoring terminal, and the fault monitoring relay gateway transmit power and network status information to the fault monitoring system control host via the communication gateway. After preliminary processing, the fault monitoring system control host transmits the status information to the fault monitoring and determination system via the communication network.

[0007] Furthermore, the wireless communication technology of the wireless transceiver is LoRa technology.

[0008] Furthermore, the fault monitoring and determination system includes a fault monitoring system server and a fault monitoring platform.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the wireless monitoring system for power grid faults in underground space electromechanical systems, by setting up power and network fault monitoring equipment at key power and network nodes of the monitored electromechanical system, monitors the power and network status of key nodes and transmits the status information to the background fault monitoring platform through the communication gateway and control host, and the platform determines the cause and location of the fault when the electromechanical system fails.

[0010] The aforementioned power and network fault monitoring terminal is used to collect the power and network connectivity status of the monitored key nodes and transmit the status information wirelessly to the fault monitoring system control host. After collecting the power grid status of the monitored key power and network nodes, the control host processes the information and transmits it to the fault monitoring system platform. The system platform simultaneously collects the online information of each device and uses the platform's internal logic algorithm to determine whether there is a fault in the power or network path of the disconnected faulty device or whether the device itself has malfunctioned. This utility model can effectively monitor the key node locations of electromechanical systems, making up for the current lack of fault monitoring systems for underground space electromechanical systems on the market, and has high practical value.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-2 The wireless transceiver uses LoRa technology for wireless communication. The fault monitoring and judgment system 8 includes a fault monitoring system server 6 and a fault monitoring platform 7.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-2 It also includes the following steps: Step S1: When installing power fault monitoring terminal 1, ensure that its monitoring power is drawn from the node's output power, and that the monitoring terminal itself is powered by the node's input power. When installing network fault monitoring terminal 2, ensure that it is powered by the network node's input power, and that the network node it monitors should be able to communicate with other nodes.

[0019] Step S2: Record the node positions of each monitoring terminal in the power and network paths, i.e., the top-down power-on sequence and communication sequence, and store them in the fault monitoring server to form a power topology map and a network topology map of the monitoring system. The two maps overlap in monitoring at the interrelated nodes.

[0020] Step S3: Introduce an alert mechanism and a polling mechanism. The online status of other electromechanical system equipment is synchronously incorporated into the fault monitoring and judgment system for monitoring. When equipment goes offline, the fault monitoring system immediately becomes alert and activates fault monitoring processes S4–S10. Under normal circumstances, the fault monitoring platform 7 remotely controls the control host 5 at regular intervals to poll each control terminal, activating fault monitoring processes S4–S6. If the polling results are abnormal, fault monitoring processes S7–S10 are activated.

[0021] Step S4: The power fault monitoring terminal 1 on the single path of the topology map reads the key status parameters of power saving and uploads them through the LORA wireless network.

[0022] Step S5: The network fault monitoring terminal 2 on the topology map association path reads the network status parameters and uploads them through the LORA wireless network.

[0023] Step S6: The power and network data of all monitoring terminals on the path are uploaded to the control host 5 via the relay gateway. After preliminary processing, the data is uploaded to the fault monitoring system server 6. The server compares the received data with the normal data.

[0024] Step S7: If the received data differs significantly from the normal data or the fault monitoring system triggers the alarm mechanism, the fault monitoring platform 7 will immediately push an alarm to the underground space management personnel.

[0025] Step S8: The fault monitoring system server 6 will call up the data of all nodes on the power / network path where the abnormal node is located and the associated network / power path, and make a judgment based on the internal fault monitoring logic algorithm to confirm the specific cause and location of the fault.

[0026] Step S9: After obtaining the cause and location of the fault, the fault monitoring platform 7 will push the cause and location of the fault to the underground space maintenance personnel. The maintenance personnel will then proceed to the fault site to troubleshoot the problem.

[0027] Step S10: After troubleshooting and deactivating the alarm, the fault monitoring server will generate a record report of the entire fault process and store it on the server.

[0028] This invention can effectively monitor key nodes of electromechanical systems, making up for the lack of fault monitoring systems for underground space electromechanical systems on the market, and has high practical value.
