Description

Technical Field

[0001] The invention relates to the field of electric power technology, and in particular to a monitoring system for a cable well cover. Background Art

[0002] With the increasing number of urban cable laying in the power system, the number of cable wells is increasing. When the cable wells are damaged by external forces or man-made damage, if the real-time monitoring device and platform can be used to predict and locate the abnormal situation of the cable wells in time, and arrange repairs and rectifications and feedback results in time, a large amount of manpower and material resources for manual inspections can be saved at the same time, the anti-theft and anti-fall safety of the cable wells can be ensured, and the safe and stable operation of the power grid system can be guaranteed, which will have huge social and economic benefits.

[0003] The geological changes in the cable well cause the cable well cover to shift, tilt, or be pried open manually. When the well cover is damaged or overturned, it is easy to identify. The changes in the light at the bottom of the cable well and the changes in the inclination of the cable well itself can detect the changes in the state of the cable well cover. Combined with the real-time positioning of the cable well, it is very easy to determine whether the cable well has been pried open, tilted, or fallen. There are currently two main ways to achieve cable well status detection.

[0004] Remote camera monitoring, install dedicated 4G cameras around the cable well, use the camera to take videos and photos of the cable well, and monitor the cable well status through AI algorithm comparison. When the system identifies tilt, drop, pry open, etc. through photos, it will push the abnormal detection results to the data center, and the system center will assign the abnormality to the patrol personnel in the designated area for on-site identification and processing. However, due to the complex construction site of the cable well, the installation conditions of the camera and the power supply conditions cannot be met, the behavior of urban residents is highly disruptive, the cost of the camera and the high cost of construction and operation and maintenance, etc., this method is limited to large-scale use and cannot form a systematic monitoring and management.

[0005] A tilt sensor is installed on each cable manhole cover. A tilt sensor, 4G module and battery are embedded at the bottom of each cable manhole cover. When the sensor detects that the tilt angle of the equipment is greater than the set value, the alarm information will be pushed to the system background, which will be pushed to the designated inspection personnel for on-site identification and processing. However, this method embeds a tilt sensor in each cable manhole cover, which directly leads to high construction costs, short service life of batteries as disposable consumables, and high replacement and maintenance costs in the later stage.

[0006] The probability of abnormal conditions such as tilting and falling caused by artificial prying of the cable well of the power system is very high. In order to ensure the safety of electricity use, there are various monitoring methods based on the cable well cover. However, due to the large number of cable wells and the wide and complex distribution of cable wells, the engineering construction of the monitoring equipment is high, the operation and maintenance cost is high, and the interference is large. The existing camera or tilt sensor cable well monitoring method cannot be installed on a large scale due to installation conditions, strong interference, and high cost. Summary of the invention

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, without paying creative labor, other drawings obtained based on these drawings still belong to the scope of the present invention.

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 FIG. 1 is a schematic diagram of an embodiment of a cable manhole cover monitoring system provided by the present invention. In this embodiment, the system includes:

[0025] Monitoring terminal, detection control terminal and mobile control terminal; the monitoring terminal is arranged on the cover plate of the cable well cover, and the detection control terminal is respectively connected to the monitoring terminal and the mobile control terminal in communication; the monitoring terminal is used to monitor the state parameters of the cable well cover in real time, compare the monitored state parameters with the normal state standard of the cable well cover, and determine whether the cable well state has abnormal changes according to the comparison results; when abnormal changes occur, abnormal alarm information is output to the detection control terminal; wherein the state parameters at least include tilt parameters, light parameters and positioning parameters; the detection control terminal is used to output corresponding control instructions to the monitoring terminal, and display the detection results of the cable well cover according to the information returned by the monitoring terminal; the mobile control terminal is used to receive the display information output by the detection control terminal, and input corresponding control instructions to the detection control terminal. Multiple monitoring terminals are arranged on the cable well cover, and the multiple monitoring terminals are respectively connected to the monitoring terminal in communication. It can be understood that it is composed of a distributed positioning terminal device (monitoring terminal), a detection control terminal (cloud platform) and a mobile control terminal (mobile communication). Users can view defect diagnosis and real-time monitoring data at the main station or by logging in to the corresponding page through the mobile terminal App. The monitoring terminal and the main station are connected through a 4G module private network. Each monitoring terminal is arranged in a distributed manner. 1-3 sets are installed in each cable well depending on the width of the cable well cover. The terminal monitors the cable well cover inclination, light perception, positioning and other parameters in real time. When the state of the cable well changes abnormally, it comprehensively analyzes multiple data such as light, inclination, positioning, etc., eliminates false alarms caused by interference factors through algorithms, and pushes the real cable well abnormal alarm information to the platform through the 4G network. Cloud platform, used to deploy intelligent analysis application software system for cable wells. The monitoring system of the cable well can realize the functions of cable well cover opening warning, tilt warning and precise positioning.

[0026] In one embodiment, the monitoring terminal at least includes a cable well detector, which is used to collect light-sensing signals, inclination signals and positioning information in real time; and determine the corresponding light-sensing parameters through the collected light-sensing signals, determine the corresponding inclination parameters through the inclination signals, and determine the corresponding positioning parameters through the positioning information. It is understandable that the cable well detector can collect light-sensing signals, inclination signals, and real-time positioning information. The cable well detector is equipped with a 4G module, and uploads data to the server through the MQTT protocol, which can accurately detect the light intensity, ectopic state, and falling state of the cable well. And according to the combination of the three data, non-real abnormal faults are filtered out. At present, similar cable well detection equipment products on the market often use simple inclination detection and camera detection, which cannot accurately distinguish between interference faults and real fault conditions. Among them, the intelligent sensor equipped with the cable well detection terminal adopts a composite detection method of light sensing, inclination, and positioning, and the detection result is reliable, strong in interference resistance, and reduces the risk of false alarms. The terminal has low construction cost and low operation and maintenance cost. Each cable well group only needs to install one cable well cover every three cable well covers to achieve monitoring. The installation cost of each cable well is 50% lower than that of similar equipment on the market. At the same time, the operation and maintenance cost is low, no external power supply is required, and there is no need to frequently replace batteries.

[0027] The monitoring terminal also includes a communication module for transmitting state parameters to the detection control terminal and receiving control instructions sent by the detection control terminal. It also includes an energy storage battery pack and a photovoltaic panel; the energy storage battery pack is used to output power signals for the monitoring terminal, and the photovoltaic panel is used to charge the energy storage battery pack. Understandably, the terminal adopts inductive power supply and solar photovoltaic power supply, ultra-low power consumption design, and is equipped with rechargeable batteries. When the lighting is ideal and the power of insufficient magnetic field power supply is provided by the battery, full speed operation is achieved at a primary current of 0.02mA. In the case of a line power outage, it can still work continuously for more than 90*24 hours. The system realizes energy self-sufficiency and independent operation, which not only reduces the cost of external power supply, but also eliminates the interference of unstable external power supply factors.

[0028] In one embodiment, the monitoring terminal is also used to filter the state parameters through a preset abnormality judgment module, and compare the filtered state parameters with the normal state standard of the cable manhole cover to generate corresponding comparison results; wherein the abnormality judgment module identifies and deletes interference data in the state parameters through a preset data processing algorithm.

[0029] In one embodiment, the cable well detector is also used to obtain the working status signals of the energy storage battery pack and the photovoltaic panel in real time. If the working status signals of the energy storage battery pack or the photovoltaic panel are abnormal, a corresponding alarm signal is generated. It is understandable that the system has its own alarm system. When the energy storage system and the photovoltaic system stop working abnormally, they will be reported to the system synchronously, which can avoid system failure in advance. The monitoring terminal structure adopts an upper and lower two-layer structure, which is stable and reliable. Supports live installation and disassembly.

[0030] In summary, the implementation of the embodiments of the present invention has the following beneficial effects:

[0031] The cable manhole cover monitoring system provided by the present invention monitors the inclination angle of the cable manhole cover and the light and position information inside the cable manhole, and accurately monitors in real time whether it is out of position, damaged, or tilted, and pushes the information to inspection personnel through the cloud platform system, so as to quickly respond to and handle abnormal problems in the cable manhole and ensure the safety of power grid use.

[0032] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
