Description

Technical Field

[0001] This patent relates to a power equipment fault detection and location device, specifically an intelligent detection device for quickly locating faulty plug-in boxes in a busbar system. It combines IoT edge computing, audio-visual guidance, and mobile terminal interaction technology to achieve visual identification and maintenance navigation of fault points. Background Technology

[0002] Currently, in power distribution systems or busbar applications, fault detection and location of plug-in boxes (such as electricity meter plug-in boxes) mainly rely on the following methods:

[0003] 1. Situation where manual inspection is used

[0004] Maintenance personnel need to periodically use multimeters, clamp meters, and other tools to test each connector box individually, or rely on alarms from the back-end monitoring system before going to the site to troubleshoot. This method is inefficient and makes it difficult to quickly locate specific fault points, especially in bus systems with multiple connector boxes connected in parallel, where troubleshooting is time-consuming.

[0005] 2. Use of centralized monitoring systems

[0006] Some systems employ centralized data collection, where gateway devices aggregate data from various electricity meters and upload it to the cloud or local server. Maintenance personnel then use monitoring software to view abnormal data. However, this approach suffers from vague location issues: the system can only indicate an anomaly in a specific busbar junction box, but it cannot pinpoint the exact location of the box, requiring manual inspection of each box for troubleshooting.

[0007] 3. Basic status indicator lights

[0008] The junction box is equipped with a simple LED indicator light to indicate the on / off status by being constantly lit or flashing. However, it has a limited function, cannot distinguish the type of fault or the degree of urgency, and lacks remote interaction capabilities. During maintenance, it still requires human experience to make judgments.

[0009] The main drawbacks of existing technology:

[0010] 1. Low fault location efficiency: It relies on manual troubleshooting and cannot achieve fast and accurate fault location guidance.

[0011] 2. Insufficient interactive capabilities: The lack of on-site audio-visual guidance and mobile terminal collaboration navigation mechanism makes it difficult for maintenance personnel to quickly reach the target location.

[0012] 3. Information isolation: Historical maintenance records of equipment are not linked to real-time fault data, resulting in a lack of data support for maintenance decisions. Utility Model Content

[0013] To address the shortcomings of existing technologies, this invention provides an intelligent detection device for quickly locating faulty plug-in boxes in busbar systems.

[0014] This utility model discloses a detection device for quickly locating faulty plug-in boxes, comprising a gateway plug-in box and one or more electricity meter plug-in boxes. The gateway plug-in box has an internal fault signal control section, which includes a Raspberry Pi, a LoRa module, a buzzer, and a beacon Bluetooth beacon. The Raspberry Pi communicates wirelessly with the power distribution room server and the electricity meter plug-in box via the LoRa module, and is electrically connected to the buzzer and the beacon Bluetooth beacon. The electricity meter plug-in box has a signal receiving section, which includes a receiving device inside the box and a display device outside the box. The receiving device includes a Raspberry Pi and a LoRa module, with the Raspberry Pi electrically connected to both the display device and the LoRa module.

[0015] Furthermore, the electricity meter junction box is equipped with an identification section, which is located on the box cover and includes an IoT QR code.

[0016] Furthermore, the IoT QR code is a rotatable identifier.

[0017] Furthermore, the display device includes a handle recess in the plug box, a light strip, and a transparent cover plate, with the light strip installed in the handle recess and the transparent cover plate covering the light strip.

[0018] Furthermore, the handle of the plug-in box is divided into upper handle, lower handle and side handle, and the light strip is installed on each handle.

[0019] Furthermore, the sound-producing device is a buzzer.

[0020] Furthermore, the gateway plug-in box is equipped with a data acquisition section, which includes a gateway. The gateway draws power from the bus and is wired to the power distribution room server via a network cable to upload the power data collected by the power meter plug-in box. The power meter plug-in box is also equipped with a data acquisition section, which includes a power meter. The power meter draws power from the bus and collects the power data from the bus. The gateway and the power meter communicate via an RS485 signal line.

[0021] Furthermore, the fault signal control section of the gateway plug-in box draws power from the gateway, while the signal receiving section of the electricity meter plug-in box draws power from the electricity meter.

[0022] Furthermore, the gateway and the electricity meter are electrically connected to the bus via an air switch.

[0023] Compared with existing technologies, this invention can improve fault location efficiency, enhance human-computer interaction and ease of operation, reduce maintenance costs and energy consumption, and improve system reliability and maintainability. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] See Figures 1 to 4 The structure of this technical solution includes two parts: a gateway plug-in box 100 and an energy meter plug-in box 200. These two parts are connected by a signal line.

[0030] The gateway junction box 100 consists of an air switch 110, a gateway 120, a Raspberry Pi 130, a beacon Bluetooth beacon 140, a buzzer 150, and a LoRa module 160. It is divided into two parts: the gateway 120 and air switch 110 form the data acquisition section, while the remaining components form the fault signal control section. The data acquisition section acquires the electrical data collected by all the electricity meter junction boxes 200 on the busbar. The fault signal control section provides navigation, audible fault alerts, and sends signals to control the indicator lights on the busbar where the faulty junction box is located. The data acquisition section is connected so that the gateway 120 draws power from the busbar via the air switch 110. The fault signal control section is connected so that the Raspberry Pi 130 draws power from the gateway 120, and the Raspberry Pi 130 is electrically connected to the LoRa module 160, the buzzer 150, and the beacon Bluetooth beacon 140.

[0031] The electricity meter junction box 200 can be divided into a data acquisition section, a signal receiving section, and an identification section. The data acquisition section uses the electricity meter 220 to collect the current circuit's electrical energy data and waits for the gateway 120 to collect it uniformly. The signal receiving section receives signals from the Raspberry Pi at the gateway junction box 100 to determine the switching, color, and flashing frequency of the LED strip. The identification section displays the junction box's number and QR code information. The data acquisition section consists of an air switch 210 and an electricity meter 220. The electricity meter 220 draws power from the busbar through the air switch 210 and collects the busbar's electrical energy data. The gateway 120 communicates with the electricity meter 220 via an RS485 signal line. The signal receiving section draws power from the electricity meter 220 and consists of a Raspberry Pi 230, a LoRa module 240, and external components including a junction box handle recess, a handle LED strip 250, and a transparent cover. The identification section consists of a rotatable identification tag 260 on the outside of the box.

[0032] This invention discloses a detection device for quickly locating faulty plug-in boxes. The device consists of a fault signal control section for a gateway plug-in box 100 and a signal receiving section for an electricity meter plug-in box 200. The fault signal control section is located inside the gateway plug-in box 100 and consists of a Raspberry Pi 130, a LoRa module 160, a buzzer 150, and a beacon Bluetooth beacon 140. These components are tightly arranged in a groove inside the box. The Raspberry Pi 130 communicates wirelessly with the power distribution room server 300 and the electricity meter plug-in boxes 200 via the LoRa module 160 to determine which electricity meter plug-in boxes 200 on its busbar are faulty, and then sends control signals to the designated plug-in boxes via the LoRa module 160.

[0033] In this scenario, the Raspberry Pi 130 controls the beacon Bluetooth beacon 140 to emit a Bluetooth signal and wait for a connection. When maintenance personnel use a mobile device to access the application on the power distribution room server 300, they can see Bluetooth signal points appearing in the power distribution room. Clicking on these points will display a navigation route on the mobile device, and the Raspberry Pi 130 will control the buzzer 150 to sound an alarm.

[0034] The signal receiving section of the electricity meter junction box 200 is divided into a receiving device located inside the box and a display device located outside the box. The receiving device consists of a Raspberry Pi 230 and a LoRa module 240, which are tightly installed in a recess inside the box. The Raspberry Pi 230 receives control signals from the gateway junction box 100 through the LoRa module 240. The display device outside the box consists of a handle recess, LED strips 250, and a transparent cover. The handles of the junction box are divided into upper, lower, and side handles. Considering that in the actual situation where junction boxes are installed on the busbar, some are installed in front of the busbar and some are installed behind the busbar, LED strips 250 are installed on each handle. LED strips 250 are installed not only in the front handle but also in the rear handle, so that maintenance personnel can easily see the LED strip of the faulty junction box from all angles. The signal receiving section works as follows: upon receiving a control signal from the gateway junction box 100, the Raspberry Pi 230 controls the LED strip to illuminate; the LED strip displays different colors depending on the fault level; and the LED strip flashes at different frequencies depending on the frequency of the fault. Thus, after arriving at the gateway junction box 100, guided by the navigation route and alarm sounds, maintenance personnel look at the power meter junction boxes 200 on the busbar where this box is located. Based on the color and flashing frequency of the LED strips outside these boxes, they determine the maintenance sequence and arrange the work accordingly.

[0035] The identification portion of the electricity meter junction box 200 is located on its cover and consists of a recessed identification groove and a rotatable identification label 260. Normally, the label displays the junction box's number recorded in the server 300. Rotating the label reveals the IoT QR code label 260, achieving dust and dirt protection while also facilitating identification of which junction boxes are under maintenance and their identification numbers. After determining the maintenance sequence, maintenance personnel unscrew the label of the target junction box and scan the QR code label 160 using a mobile device to obtain the target junction box's historical maintenance records and basic information, aiding in the maintenance process. After maintenance, the personnel unscrew the label back. Since the gateway 120 collects normal data from the electricity meter 220, the Raspberry Pi 130 in the gateway junction box 100 sends a signal to turn off the LED strip 260 of the completed electricity meter junction box 200, confirming the completion of maintenance.

[0036] Existing fault location technologies are inefficient, relying on manual troubleshooting and failing to provide rapid and accurate fault location guidance. Maintenance personnel often need to use tools to check various indicators of each junction box sequentially, which is laborious and time-consuming. Even with a centralized monitoring system that collects data from each junction box, maintenance personnel still need to access the system to identify which junction boxes are faulty, and then navigate through each busbar in the distribution room to find the specific box, resulting in low efficiency. Using this device, maintenance personnel can achieve point-to-point navigation for each faulty junction box, quickly and accurately locating it for work, improving maintenance efficiency and reducing operation and maintenance costs.

[0037] Existing technologies lack sufficient interactive capabilities during fault detection at the connector box, and lack a navigation mechanism that integrates on-site audio-visual guidance with mobile terminal coordination, making it difficult for maintenance personnel to quickly reach the target location. Often, it relies on the maintenance personnel's familiarity with the site and on-site road signs, requiring them to spend time learning. This device, through audio-visual guidance combined with the maintenance personnel's mobile devices, can provide a fast and accurate navigation experience.

[0038] Existing technology suffers from isolated information, with historical equipment maintenance records and real-time fault data not linked, resulting in a lack of data support for maintenance decisions. When repairing faulty junction boxes, maintenance personnel often rely on past experience, leading to inconsistent repair results. Faced with a large volume of maintenance tasks, personnel struggle to obtain data to support their decisions, often relying solely on the time of fault occurrence and the junction box's location. This device helps maintenance personnel access historical equipment maintenance records, referencing previous experience; it also visualizes fault conditions, providing clearer support for making maintenance decisions.

[0039] The fault detection device proposed in this utility model, through its innovative hardware architecture and intelligent interactive design, significantly improves the efficiency of fault location and maintenance in busbar systems. Specific technical effects are as follows:

[0040] 1. Significantly improves fault location efficiency

[0041] Reduced location time: Bluetooth beacon navigation + buzzer guidance + light strip visual prompts reduce the time for maintenance personnel to reach the fault point from an average of 15 minutes (manual troubleshooting) to within 5 minutes. Bluetooth is normally turned off in the gateway box to reduce interference, and the beacon is only activated when a fault occurs. Combined with mobile navigation and buzzer sound guidance, it solves the problem of finding the target device quickly in densely installed environments.

[0042] 2. Enhance human-computer interaction and ease of operation

[0043] The fault information is presented intuitively: the color (such as red / yellow / green) is used to distinguish the urgency of the fault, and the light frequency reflects the frequency of abnormal occurrence. It provides more fault information than the traditional single LED indicator. The combination of multi-color light strips and flashing frequency can distinguish various faults such as overload, short circuit, and communication interruption, and the time for determining the repair priority is reduced by 90%.

[0044] Seamless collaboration on mobile devices: Maintenance personnel can navigate to the target gateway with one click through the application, and then locate the faulty plug box according to the light strip prompts, without the need for manual consultation of drawings or backend data.

[0045] 3. Reduce operation and maintenance costs and energy consumption

[0046] Reduce labor costs: Precise fault location avoids ineffective inspections, saving a significant amount of manual troubleshooting time each year.

[0047] Low power consumption design: The Bluetooth beacon is only activated in case of a fault, and the daily standby power consumption is close to 0. The overall device power consumption is reduced by 60% compared with normally open wireless monitoring equipment, which not only reduces power consumption, but also avoids signal interference from multiple devices and improves the positioning accuracy of maintenance personnel.

[0048] 4. Improve system reliability and maintainability

[0049] Digitalized maintenance records: Scanning a QR code allows access to equipment lifecycle data (such as historical faults and maintenance records), solving the problems of easily damaged traditional paper labels and delayed information updates. Furthermore, the QR code is normally tucked inside, displaying the junction box label, and is only unscrewed during maintenance, taking dust prevention into consideration. Scanning to access equipment lifecycle data reduces maintenance plan development time by 50% and avoids errors caused by missing records.

[0050] This invention achieves an upgrade in fault location from "passive response" to "active guidance" and maintenance decision-making from "experience-driven" to "data-driven" through hardware-software collaborative innovation. It is particularly suitable for high-density power distribution scenarios (such as data centers and photovoltaic power plants) and is expected to reduce the mean time to repair (MTTR) of the system by more than 75%.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
