Abstract
Description
Technical Field
[0001] This invention relates to the field of power distribution network environment image processing technology, and in particular to a power distribution network environment image processing system and method. Background Technology
[0002] A distribution network is a power grid in which the transmission network or regional power plants receive electrical energy and distribute it locally or tiered according to voltage to various users through distribution facilities. Real-time monitoring of the distribution network requires a distribution network environment image processing system. This system is a device capable of real-time monitoring, imaging, and comparing the location of the distribution network. It mainly consists of infrared components, timing components, imaging components, comparison components, and alarm components. The infrared component detects the current flowing through the conductors in the distribution network. As the current flows, it generates heat due to the conductor's resistance. This increased temperature causes the conductor to emit infrared radiation, which is received by the infrared receiving unit within the infrared component. Based on the location of the received infrared radiation, the infrared component determines the conductor's position and transmits this position to subsequent units. The distribution network environment image processing system features fast detection speed, real-time monitoring, and timely alarm functions.
[0003] In common infrared components used for monitoring conductor positions, the conductors are often encased in thick optical cables, so only a small portion of the heat generated by the conductors is transferred to the outside through the cables. This results in relatively low infrared radiation emitted by the conductors, leading to inaccurate positioning of the infrared radiation received by the components. Furthermore, many optical cables in a power distribution network are often bundled together, and the infrared components can only determine the number of cables by the intensity of the received infrared radiation. Since some conductors have higher resistance and generate more heat, they produce stronger infrared radiation, which can cause misjudgments by the infrared components, resulting in errors in the transmitted information.
[0004] Existing image processing systems for power distribution networks have limitations when monitoring incoming conductors, including the inability to accurately detect conductor positions and determine the number of conductors at the same location. Summary of the Invention

[0056] Figure 3 This is a schematic diagram of the main flow of a power distribution network environment image processing method in an embodiment of the present invention. Detailed Implementation
[0057] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0058] like Figure 1 and Figure 2 The diagram shown is a schematic representation of an embodiment of a power distribution network environment image processing system provided by the present invention. In this embodiment, the system includes:
[0059] The data acquisition module, preprocessing module, information processing module, analysis module, and human-computer interaction module are connected in sequence.
[0060] The acquisition module sends electrical and optical signals to each conductor in the power distribution network according to a predetermined cycle based on the received acquisition instructions, and detects the infrared radiation signals generated by each conductor in the power distribution network in real time.
[0061] The preprocessing module compares the real-time detected infrared radiation signal with the preset rated radiation value range, and determines whether to re-acquire the infrared radiation signal generated by each conductor in the power distribution network or output the infrared radiation signal and the light signal based on the comparison result.
[0062] The information processing module calculates the position and quantity of each conductor in the power distribution network based on the received infrared radiation signals, optical signals and position information of each conductor in the power distribution network, and outputs the corresponding digital signal based on the statistical results.
[0063] The analysis module sends control signals to the acquisition module according to a predetermined period and records time information;
[0064] The human-machine interaction module determines the power distribution network status for the current time period based on the digital signal output by the information processing module, compares the power distribution network status for the current time period with the reference power distribution network status, and determines whether to trigger an alarm based on the comparison result.
[0065] In a specific embodiment, the acquisition module includes at least: an acquisition circuit unit, an optical signal transmitting unit, an optical signal receiving unit, an infrared radiation receiving unit, and an acquisition chip. The acquisition circuit unit sends a start signal to the acquisition chip at a predetermined cycle according to the received acquisition command. The acquisition chip sends control signals to the optical signal transmitting unit and the infrared radiation receiving unit according to the received start signal. The optical signal transmitting unit sends optical signals to the wires connected to it according to the received control signal. The optical signal receiving unit acquires the optical signals of the wires connected to it according to the received control signal. The infrared radiation receiving unit acquires the infrared radiation signals of each wire according to the received control signal. It is understood that when the acquisition module is working, the operation of the acquisition circuit unit is automatically controlled by a computer at regular intervals. The acquisition circuit unit can be connected to the computer, and its operation can be automatically controlled every 10 minutes according to the time displayed on the computer.
[0066] When the acquisition circuit unit is operating, the control circuit unit sends an electrical signal to the acquisition chip to control the acquisition chip to operate. The acquisition chip can control the optical signal emitting unit and the infrared radiation receiving unit to work.
[0067] During operation, the acquisition chip enables the infrared radiation receiving unit to work. The infrared radiation receiving unit can generate infrared radiation of different intensities due to the heating of different wires in the power grid. At the same time, the acquisition chip controls the operation of the optical signal transmitting module. During operation, the optical signal transmitting module emits invisible light into the power distribution network through a light source. The invisible light can be received by the optical signal receiving unit after being reflected by the wires in the power distribution network.
[0068] The infrared radiation receiving unit can receive radiation with an accuracy of 1nm to 760nm, and the infrared radiation generated by the power lines in the power distribution network is always within the receiving range of the infrared radiation receiving unit.
[0069] In this embodiment, the preprocessing module includes at least a comparison unit and a selection unit. The comparison unit compares the data collected by the acquisition module with reference data and determines whether to send an electrical signal to the selection unit based on the comparison result. The selection unit determines whether to restart the acquisition module based on the received electrical signal. It is understood that after the acquisition module collects data, the comparison unit compares it with the reference data. When the infrared radiation value received by the infrared radiation receiving unit is less than or greater than five times the rated radiation value, the comparison unit sends an electrical signal to the selection unit. The selection unit discards this value and resends a restart signal to the acquisition module, causing the acquisition module to restart and re-acquire data.
[0070] Specifically, the comparison unit is used to send an electrical signal to the selection unit when the infrared radiation value received by the infrared radiation receiving unit is less than or greater than the rated radiation value range;
[0071] When the infrared radiation value received by the infrared radiation receiving unit is within the rated radiation value range, no electrical signal is sent to the selection unit, and the received infrared radiation value is output.
[0072] Specifically, the selection unit is used to generate and output a re-acquisition command to the acquisition module when an electrical signal is received, thereby controlling the acquisition module to restart and realize the re-acquisition of the infrared radiation signal.

The signal digital conversion unit is used to convert the information transmitted by the judgment unit into a digital signal. The display unit is used to display the received digital signal as a power distribution network image. It is understood that the information receiving unit is used to statistically analyze the amount and location of infrared radiation received by the infrared receiving unit, collect the location and magnitude of emitted light signals, the judgment unit is used to determine the location and quantity of each conductor in the power distribution network based on the information received by the information receiving unit, the signal digital conversion unit is used to convert the information transmitted by the judgment unit into a digital signal, and the display unit is used to display the power distribution network image using the received digital signal. It should be noted that the information processing module is a CPU, which has an internal storage unit for storing the power distribution network reference template. The signal digital conversion unit is used to convert the signals transmitted by the judgment unit into hexadecimal digital signals. The display screen is used to receive the hexadecimal digital signals, convert them into images, and display them.
[0074] In this embodiment, the analysis module includes at least a time unit and a control unit. The time unit records time and sends signals to the control unit according to corresponding time intervals. The control unit controls the acquisition chip to generate control signals based on the signals sent by the time unit. It is understood that the time unit records time and sends signals to the control unit according to corresponding time intervals, and the control unit controls the infrared dual-light module to operate based on the signals sent by the time unit. It should be noted that the interval of the time module in the analysis module is manually controlled, with a minimum interval of 10 minutes and a maximum interval of 24 hours. The default value is set to 10 minutes, and the control unit can control the infrared dual-light module to operate.
[0075] In this embodiment, the human-machine interaction module includes at least a verification unit and an alarm. The verification unit compares the current distribution network status with a reference distribution network status and determines whether to generate an alarm signal based on the comparison result. When the alarm receives the alarm signal generated by the verification unit, the alarm performs an alarm action. It can be understood that the verification unit is used to compare the current distribution network status with a reference distribution network status, and the alarm operates after receiving the signal transmitted by the comparison unit.

[0085] The alarm receives signals and operates to trigger an alarm.
[0086] The displacement differences obtained at the same location at different times in the above steps are then cyclically analyzed across multiple locations to compare the distribution network at different times. This is used to compare the location of the distribution network at different times with the location of a reference distribution network to determine the state of the distribution network.
[0087] It should be noted that the system described in the above embodiments corresponds to the method described in the above embodiments. Therefore, the parts of the method described in the above embodiments that are not described in detail can be obtained by referring to the content of the system described in the above embodiments, and will not be repeated here.
