Description

Technical Field

[0001] This utility model relates to the field of cable monitoring technology, and in particular to a device for monitoring the operating status of urban lighting cables. Background Technology

[0002] As a crucial component of municipal infrastructure, urban lighting cables are constantly exposed to complex and changing natural and man-made environments. They are frequently affected by natural factors such as diurnal temperature variations, seasonal humidity changes, and ultraviolet radiation. Furthermore, the underground spaces in cities experience chemical corrosion and mechanical vibrations, making the cable insulation layer highly susceptible to deterioration and cracking. These hazards not only affect the normal operation of urban lighting systems but also pose a risk of electrical leakage accidents, thus threatening public safety.

[0003] Currently, the monitoring of urban lighting cables mainly relies on a traditional method combining manual inspection and offline experiments (such as withstand voltage testing and insulation resistance testing). This approach is not only inefficient but also fails to detect hidden defects such as cable insulation aging and joint oxidation. Although online monitoring technology has developed in recent years, existing methods generally suffer from limited functionality and poor adaptability. For example, detecting leakage current in cables using residual current monitors is only applicable to obvious leakage faults and is difficult to use for leakage early warning; while infrared thermal imaging can monitor abnormal cable temperatures to locate overheated areas, it cannot detect internal insulation degradation; and partial discharge detection technology (which uses high-frequency sensors to capture partial discharge signals in cables) is easily affected by the complex electromagnetic environment of urban areas, making it difficult to guarantee accuracy and sensitivity. In practical applications, these technologies often fall short in some aspects and fail to comprehensively assess the operating status of urban lighting cables. Utility Model Content

The monitoring module is used to monitor the operating status of the cable and feed back data information to the control module. The control module is used to classify the data information to identify abnormal operating states of the cable and transmit the data information to external devices through the communication module.

[0028] Example 1:

[0029] This utility model proposes a device for monitoring the operating status of urban lighting cables.

[0030] In one embodiment of this utility model, a city lighting cable operation status monitoring device 100 includes a housing 1 and a control module, a monitoring module, and a communication module disposed within the housing 1 and integrated on a circuit board 2. The housing 1 is detachably installed inside a street lamp 200 and electrically connected to an external power supply. The monitoring module is used to monitor the operation status of the cable and feed back data information to the control module. The control module is used to classify the data information to identify abnormal operation status of the cable and transmit the data information to external devices through the communication module.

[0031] Specifically, such as Figures 1 to 4 As shown, in the urban lighting cable operation status monitoring device 100 of this utility model, the control module, monitoring module, and communication module are integrated on the circuit board 2, making the connection between the modules simpler, reducing the use of cables, and reducing internal complexity. Simultaneously, the circuit board 2 is housed within the housing 1, which provides shielding and protection for the circuit board 2 and each module, effectively preventing damage from the external environment, such as physical impact, humidity, dust, and electromagnetic interference, ensuring stable operation of the equipment. Furthermore, in actual use, the urban lighting cable operation status monitoring device 100 can be installed into the lamp post of the street light 200 using threaded connections or other methods. The lamp post's wall not only provides secondary shielding for each module, further improving the protection effect, but also eliminates the need for additional monitoring lines, as power can be supplied by the lighting cable of the street light 200, reducing installation costs and complexity. Moreover, as urban infrastructure, the lamp post is fixed in location and easily accessible, thereby improving the convenience of maintenance and management of this utility model.

[0032] It is worth noting that although the urban lighting cable operation status monitoring device 100 of this utility model can be electrically connected to the lighting cable to achieve power supply, since the lighting cable is only powered at specific times (at night) and is usually de-energized during the day, in order to ensure the stable operation of this utility model for a long time, an additional power supply can be set in the housing 1.

[0033] Understandably, the monitoring module can employ existing technologies such as voltage transformers, current transformers, zero-sequence current transformers, and temperature sensors. This allows for real-time monitoring of the cable's operating status, including voltage, current, capacitance, resistance, and temperature. When the monitoring module detects an abnormality in the cable's operating status, it feeds this abnormal data back to the control module. The control module automatically categorizes the abnormal data (e.g., abnormal voltage or current values ​​caused by insulation aging, outer sheath damage, or cable breakage). Simultaneously, it transmits the abnormal data to an external platform such as a cloud platform or monitoring center via the communication module. This allows staff to quickly identify any abnormalities in the lighting cable, facilitating maintenance and repair. Furthermore, the communication module can employ high-strength encryption algorithms to encrypt the data, ensuring it is difficult to interpret during transmission and preventing unauthorized tampering or control.

[0034] Compared with existing technologies, this utility model provides a city lighting cable operation status monitoring device 100. Through its monitoring module, it can comprehensively collect real-time operation data of the lighting cable, including voltage, current, capacitance, resistance, and temperature, and can complete status assessment without power outages. This not only overcomes the time limitations of traditional manual inspections, enabling continuous 24 / 7 monitoring, but also significantly improves the timeliness of fault early warning. It can accurately identify latent defects in the lighting cable operation process (such as identifying initial insulation degradation through zero-sequence current changes), ensuring the normal and stable operation of the city lighting system. Through the monitoring module, control module, and... The use of the communication module not only enables remote monitoring and real-time response to the cable's operating status, improving response speed and efficiency, but also reduces the frequency of manual inspections, increases monitoring efficiency, and reduces the workload of staff. It is convenient and reliable to use. The housing 1 and the light pole provide double shielding protection for each module, improving the protection effect. Furthermore, there is no need to lay additional monitoring lines, as the lighting cable of the street light 200 can provide power, reducing installation costs and complexity. At the same time, as an infrastructure of urban construction, the light pole is fixed in location and easily accessible, thereby improving the convenience of maintenance and management of this utility model.

[0035] In one embodiment, the system further includes a movable seat 3 for mounting the housing 1. A mounting hole 4 is provided on the side wall of the street lamp 200 for the housing 1 to extend into. A fixing rod 5 is provided inside the street lamp 200 near the mounting hole 4. A protrusion 6 is formed on the bottom surface of the movable seat 3, and a limiting hole 7 is provided on the protrusion 6 for the fixing rod 5 to pass through. Specifically, as shown... Figures 1 to 4As shown, by opening mounting holes 4 on the side wall of the street light 200 pole, workers can insert the housing 1 into the pole, resulting in a simple and reasonable structural design. Furthermore, since a fixing rod 5 is provided inside the street light 200 pole near the mounting holes 4, and a limiting hole 7 for the fixing rod 5 to pass through is provided on the protrusion 6 on the bottom surface of the movable seat 3, the movable seat 3 can slide along the extension direction of the fixing rod 5 through the insertion and engagement of the limiting hole 7 and the fixing rod 5. This allows it to extend into or retract into the street light 200 pole, facilitating the disassembly and assembly of the housing 1 and aiding in inspection and maintenance.

[0036] In one embodiment, the streetlight 200 is provided with multiple fixing rods 5, which are spaced apart along the width direction of the mounting holes 4. The number of limiting holes 7 is the same as the number of fixing rods 5, and the multiple fixing rods 5 are respectively inserted into the multiple limiting holes 7 in a one-to-one correspondence. Specifically, as shown... Figure 2 and Figure 4 As shown, the movable seat 3 can be installed and limited at multiple points by the insertion and cooperation of multiple fixing rods 5 and multiple limiting holes 7, thereby significantly improving the stability of the movable seat 3 when it drives the housing 1 to move. The structural design is simple and reasonable.

[0037] In one embodiment, a groove 8 for placing the housing 1 is provided on the top surface of the movable base 3. Specifically, as shown... Figure 4 As shown, by opening a groove 8 on the top surface of the movable seat 3 that matches the shape of the housing 1, the housing 1 can be accurately positioned and fixedly installed, so that the housing 1 can maintain a stable installation position under vibration conditions in complex environments. In addition, a buffer pad can be set in the groove 8 to further reduce the impact of mechanical shock on the electronic components inside the housing 1.

[0038] In one embodiment, pins 9 are provided on the opposite side walls of the mounting holes 4, and positioning grooves 10 are respectively provided on the outer side walls of the movable seat 3 for the pins 9 to extend into. Specifically, as shown in the figure... Figures 2 to 4 As shown, the engagement of the pin 9 with the positioning groove 10 improves the stability of the movable seat 3's movement, facilitating the disassembly, assembly, inspection, or maintenance of the housing 1 and its internal modules. Furthermore, the use of the slot and protrusion 6 provides multi-point support for the movable seat 3, ensuring that it always maintains a horizontal installation posture, thus guaranteeing the stability of the housing 1's installation and smooth movement.

[0039] In one embodiment, specifically, as Figure 2 and Figure 4 As shown, a handle 11 is provided on the side of the movable seat 3 near the mounting hole 4, which makes it easy for workers to pull the movable seat 3 out of the mounting hole 4 without the need for other auxiliary tools. The operation is simple, time-saving and labor-saving, and improves the efficiency of inspection and maintenance.

[0040] In one embodiment, such as Figures 1 to 4 As shown, the street lamp 200 is provided with a cover plate 12 for covering the mounting hole 4, and a sealing ring is provided on the side of the cover plate 12 facing the mounting hole 4. Understandably, the cover plate 12 can be installed and fixed to the surface of the street lamp 200 by means of clips or screws to cover the mounting hole 4, thereby preventing external dust, impurities, etc. from entering the mounting hole 4 and damaging the various module components inside the housing 1; the tight fit between the sealing ring and the outer wall of the street lamp 200 can effectively prevent rainwater and other environmental pollutants from entering the mounting hole 4, thus improving the protective effect.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
