However, with the complexity of the functions of online monitoring devices, especially the application of front-end AI, the requirements for power consumption are getting higher and higher.

[0062] The present invention provides a method for reducing the power consumption of an online monitoring device for a power transmission line, so as to solve the problem of excessive power consumption of the online monitoring device for a power transmission line.

[0063] Before describing the embodiments of the present application, some terms or concepts involved in the embodiments of the present application are explained.

[0064] NPU (Neural Processing Unit), a neural network processing unit is a hardware accelerator dedicated to performing deep learning and neural network calculations. It is designed to provide higher energy efficiency than general-purpose processors and is suitable for processing a large number of data-intensive AI tasks such as image recognition, speech recognition, and natural language processing.

[0065] DDR3 (Double Data Rate Third Generation Synchronous Dynamic Random-Access Memory) is a memory standard used in computers and other electronic devices.

[0066] MIPI CSI interface (Mobile Industry Processor Interface Camera Serial Interface) is a serial interface standard used to connect cameras and processors.

[0067] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

[0068] The present invention provides a method and device for reducing power consumption of an online monitoring device for a power transmission line, and combines software and hardware collaborative processing to solve the problem of excessive power consumption of the online monitoring device for a power transmission line.

[0069] According to an exemplary embodiment, the transmission line online monitoring device includes a single-chip microcomputer 111, a power management circuit 121, a core module 113, a wireless network (WIFI) module 115, a Beidou satellite navigation and positioning (GPS) module 117 and a mobile communication (4G) module 119. The single-chip microcomputer 111 is a low-power single-chip microcomputer, the WIFI module 115 and the 4G module 119 are responsible for data transmission, and the GPS module 117 is responsible for providing location information. These components work together to realize the function of online monitoring of the transmission line. See the schematic diagram of the composition of the transmission line online monitoring device. Figure 1 .

[0070] According to some embodiments, the core module includes a central processing unit (CPU), a neural network processor (NPU), a Flash memory and a DDR3 memory, and the core module mainly processes core functions, including image acquisition, real-time video generation and real-time AI analysis. The CPU is responsible for executing instruction sets and task scheduling, including image acquisition, data processing and system management, etc.; the NPU is used to perform neural network computing tasks, such as image recognition and AI analysis; the Flash memory is used to store operating systems, application codes, configuration files and long-term data, etc. The Flash memory is a non-volatile storage medium that can retain data even after power failure; the DDR3 memory is the main operating memory of the core module, which is used to store data and intermediate results of the tasks being executed.

[0071] According to some embodiments, the core module is connected to the lens module via a mipi csi interface, and the image captured by the lens module is obtained through a protocol. The image captured by the lens module can be a static photo or a continuous video stream. In addition to simple image capture, the core module can also generate a continuous video stream to more comprehensively monitor the status of the power transmission line. Real-time AI analysis enables the device to perform preliminary processing on the collected data on site, such as using artificial intelligence algorithms to identify foreign objects, damage or abnormal conditions on the wires. The synchronous analysis of the core module helps to detect potential problems in a timely manner and take measures.

[0072] According to an example embodiment, the Beidou GPS module has Beidou positioning function, time synchronization function and emergency communication function. The Beidou positioning function uses the high-precision positioning service provided by the Beidou satellite navigation system to determine the exact location of the device; the time synchronization function obtains accurate time information through Beidou satellite navigation positioning to ensure device time synchronization, which helps to record the timestamp of events; the Beidou GPS module can also send signals as an emergency communication means when the online monitoring device of the power transmission line loses other communication methods except mobile communication.

[0073] According to some embodiments, the WIFI module mainly provides a WIFI communication channel, and the online monitoring device can exchange data with external devices through WIFI. The WIFI module allows the device to exchange data with external devices through a wireless local area network (WLAN). When the device is restarted, the WIFI module is used for configuration and initialization, at which time the WIFI module will be activated and work for a short time.

[0074] The 4G module performs data exchange via 4G communication. The 4G module provides high-speed data transmission capabilities through a cellular network and performs data exchange in places without WIFI coverage, especially in remote areas or on mobile devices.

[0075] The power management circuit includes a photovoltaic panel charge and discharge control circuit, a DC voltage conversion circuit and a module power supply control circuit. The photovoltaic panel charge and discharge control circuit uses a solar panel to power the system and controls the charge and discharge process to ensure that the battery will not be overcharged or over-discharged to extend the battery life. Considering that the voltage supplied by solar energy may not be suitable for all electronic components, the DC voltage conversion circuit is used to convert the input voltage into a stable voltage suitable for use by various parts of the system. The module power supply control circuit is responsible for providing accurate power supply voltage and current according to the actual needs of each module of the system to ensure stable operation of the system.

[0076] In the online monitoring device for power transmission lines, the low-power single-chip microcomputer independently controls the core module, WIFI module, Beidou GPS module, 4G module and power management circuit. The use of a low-power single-chip microcomputer can effectively reduce the power consumption of the entire device, extend battery life, and improve the endurance of the device; the low-power single-chip microcomputer independently controls each module, simplifies the data interaction process, and simplifies the design of other modules, improving the reliability and flexibility of the entire online monitoring device for power transmission lines.

[0077] Figure 2 A schematic diagram of a method for reducing power consumption of an online monitoring device for a power transmission line according to an example embodiment is shown.

[0078] There are two working modes of the online monitoring device for power transmission lines. The first is the timed wake-up mode, and the second is the platform remote call mode. Regardless of the working mode, the core method for reducing the power consumption of the online monitoring device for power transmission lines can be found in Figure 2 .

[0079] In S101, when not in operation, the single chip microcomputer turns off the power of the core module, the wireless network module and the Beidou satellite navigation and positioning module, and the single chip microcomputer and the mobile communication module enter a sleep mode.

[0080] According to an example embodiment, when not in operation, the single-chip microcomputer turns off the power of non-communication modules such as the core module, the wireless network module and the Beidou satellite navigation and positioning module, so as to completely reduce power consumption. The single-chip microcomputer and the 4G module enter sleep mode to further reduce power consumption.

[0081] In S103, when the snapshot is started, the single chip microcomputer powers on the core module, the core module performs snapshot analysis and transmits the analysis result to the single chip microcomputer, and the single chip microcomputer turns off the power of the core module after receiving the analysis result.

[0082] According to the example embodiment, when it is necessary to start the snapshot, the single chip microcomputer powers on the core module to start the core module working, the core module performs snapshot analysis and transmits the analysis result to the single chip microcomputer, and the single chip microcomputer turns off the power of the core module after receiving the analysis result. The core module is activated only when needed, and the power is cut off immediately after the work is completed, which not only reduces the possibility of long-term standby failure but also effectively reduces power consumption.

[0083] In S105, the single chip computer uploads the analysis results to the platform via the mobile communication module.

[0084] According to the example embodiment, the single chip microcomputer uploads the analysis results to the platform through the 4G module, which can ensure that data transmission is completed when only the single chip microcomputer and the 4G module are powered, thereby reducing unnecessary power consumption of other modules.

[0085] By utilizing the method of the present invention, the online monitoring device for power transmission lines can reduce power consumption to the maximum extent while ensuring the monitoring effect, thereby improving the stability and reliability of the system.

[0086] Figure 3 A flow chart of a method for reducing power consumption of an online monitoring device for a power transmission line in a timed wake-up mode according to an example embodiment is shown.

[0087] See also Figure 3 , showing a method for reducing power consumption of an online monitoring device for a transmission line in a timed wake-up mode.

[0088] In S201, initialization.

[0089] When the system starts, the microcontroller performs initialization operations, including setting the time interval for the timed wake-up, configuring the high-speed serial port to communicate with the 4G module, and ensuring normal data transmission. The high-speed serial port uses a universal asynchronous receiver-transmitter interface for bidirectional data transmission, and the communication baud rate of the high-speed serial port is 115200 Baud.

[0090] Through the initialization operation, the microcontroller can ensure that the system is in the correct state at startup and is ready for subsequent monitoring and data transmission.

[0091] In S203, a timed wake-up is set.

[0092] According to some embodiments, the single chip microcomputer sets a timer according to a preset time interval, so that the online monitoring device captures pictures at fixed time intervals.

[0093] In S205, the single chip microcomputer responds to the modules in turn to power on.

[0094] According to an exemplary embodiment, when the preset time is reached, the timer triggers the single-chip microcomputer to wake up the system, and the single-chip microcomputer responds to the modules in turn to power on, waking up the core module, WIFI module, Beidou GPS module and 4G module.

[0095] In S207, the core module performs image acquisition and intelligent analysis, and the single chip microcomputer receives the analysis results.

[0096] According to the example embodiment, after the single chip microcomputer powers on the core module, the core module starts working to perform image acquisition and intelligent analysis. The image acquisition acquires the transmission line image acquired by the lens module through the protocol, and the core module is connected to the lens module through the MIPI CSI interface. Through the MIPI CSI interface, the camera can efficiently and low-power transmit the acquired image data to the core module.

[0097] The core module performs intelligent analysis on the collected images, identifies the state of the power transmission line using the NPU inside the core module, and sends the analysis results to the single-chip microcomputer through the high-speed serial port.

[0098] In S209, the microcontroller cuts off the power supply of other modules.

[0099] According to the example embodiment, after receiving the analysis result of the core module, the single chip microcomputer notifies the core module to stop working and turns off the power of modules that are not essential for communication, such as the WIFI module and the Beidou GPS module, so as to achieve energy-saving operation while ensuring the data transmission function.

[0100] In S211, the MCU interacts with the upper-level platform through the 4G module.

[0101] According to an example embodiment, the single-chip microcomputer communicates with the 4G module through a high-speed serial port, and the single-chip microcomputer uploads the image processing and analysis results to the platform through a communication protocol; after the data upload is completed, the single-chip microcomputer and the 4G module enter a sleep mode and wait for the next scheduled wake-up.

[0102] The method of this example embodiment transfers the protocol parsing and communication of the device and platform from the core module to the single-chip microcomputer. The core module only focuses on processing the capture and intelligent analysis functions, which not only improves the processing efficiency, but also greatly shortens the working time of the core module, thereby reducing the power consumption of the device; the single-chip microcomputer is responsible for protocol parsing and communication, which simplifies the design of the core module and improves the reliability of the system.

[0103] According to some embodiments, the protocol is I1 protocol, which is a data transmission protocol for a power transmission line status monitoring device, and specifies the data exchange format and rules between the device and the remote monitoring center. The protocol parsing and communication mainly involves the reception and transmission of complete protocol signaling, as well as the parsing of the content of the signaling. Whether the device receives and sends complete signaling, or parses the received signaling content, understands and processes instructions or data, it requires processing time. Using a lower-power master to process can achieve the effect of reducing power consumption.

[0104] The method of the present invention uses a single-chip microcomputer to process protocol parsing and control logic, and the core module only processes the capture and intelligent analysis functions, and the core module is activated only when needed, which can significantly improve the energy efficiency of the system, reduce power consumption, and maintain the stability and reliability of the system.

[0105] Figure 4 A flow chart of a method for reducing power consumption of an online monitoring device for a power transmission line in a remote summoning mode of a platform according to an example embodiment is shown.

[0106] See also Figure 4 , showing a method for reducing power consumption of an online monitoring device for a transmission line in a platform remote calling mode.

[0107] In S301, the platform remotely sends instructions to wake up the 4G module.

[0108] According to an exemplary embodiment, a work trigger instruction of the online monitoring device for the power transmission line is issued by the platform, and the platform remotely issues the instruction through the 4G network to wake up the 4G module.

[0109] In S303, the 4G module forwards the instruction to the single chip microcomputer.

[0110] According to an example embodiment, the instruction is forwarded to the single-chip microcomputer via the 4G module, and the 4G module is forwarded to the single-chip microcomputer via a high-speed UART interface.

[0111] At S305, the single chip microcomputer responds to the modules being powered on in sequence.

[0112] According to an exemplary embodiment, after receiving the instruction, the single-chip microcomputer wakes up the core module, WIFI module, Beidou GPS module and other modules that are not essential for communication in sequence.

[0113] In S307, the single chip microcomputer parses the protocol and the main control board processes the protocol.

[0114] According to an exemplary embodiment, the single-chip microcomputer receives and parses the instructions issued by the platform according to the protocol, the single-chip microcomputer notifies the main control board to process the protocol, and the main control board performs corresponding operations according to the protocol. After the single-chip microcomputer powers on the core module, it sends the parsed instructions to the core module.

[0115] In S309, the single chip microcomputer receives the processing result.

[0116] According to some embodiments, after the core module receives the instructions issued by the single-chip microcomputer, it performs image acquisition and intelligent analysis; after the core module completes the image acquisition and intelligent analysis, it sends the analysis results to the single-chip microcomputer through the high-speed UART interface. After the single-chip microcomputer receives the analysis results, it performs corresponding data processing tasks such as data storage and data upload.

[0117] At S311, the microcontroller cuts off the power supply to other modules.

[0118] According to the exemplary embodiment, after receiving the analysis result, the single chip microcomputer notifies the core module to stop working, and turns off the power of modules that are not essential for communication, such as the WIFI module and the Beidou GPS module.

[0119] In S313, the MCU interacts with the upper-level platform through the 4G module.

[0120] According to an example embodiment, the single-chip microcomputer communicates with the 4G module through a high-speed serial port, and the single-chip microcomputer uploads the image processing and analysis results to the platform through a communication protocol; after the data upload is completed, the single-chip microcomputer and the 4G module enter a sleep mode, waiting for the next platform to issue an instruction.

[0121] According to this example embodiment, in the platform remote wake-up mode, the 4G module and the single-chip microcomputer interact with each other through commands, the protocol parsing and communication between the platform are completed by the low-power single-chip microcomputer, and the core module only processes the capture and intelligent analysis functions, which can realize the efficient and low-power operation of the online monitoring device of the transmission line and improve the stability and reliability of the equipment.

[0122] For example, a signal for actively collecting pictures is sent by the platform. After receiving it, the 4G module forwards it to the MCU. The MCU analyzes the signal to actively collect pictures. The MCU only needs to notify the core module to start, collect pictures, and upload pictures to the MCU. Then the core module can be turned off, and the MCU and the platform can interact with each other. If this mode is not adopted, all work is handled by the high-power core module. During the signal reception, protocol analysis and picture upload stages, the core module needs to remain active, which will not only generate higher power consumption, but also increase the risk of system failure.

[0123] The method and device for reducing the power consumption of an online monitoring device for power transmission lines of the present invention can achieve a balance between high efficiency and low energy consumption through software and hardware collaborative processing. A low-power single-chip microcomputer is used to independently control each functional module. According to the working mode of the system, the power supply of each module is controlled by situation and region. By reasonably arranging the working time and status of each module, unnecessary energy consumption can be reduced as much as possible. The single-chip microcomputer and 4G module, which are functional modules essential for communication, enter sleep mode. While reducing power consumption, it also ensures that the device can respond quickly and execute tasks when needed. By transferring protocol parsing and data transmission to the single-chip microcomputer, the working time of the core module can be significantly reduced, thereby reducing the overall power consumption of the device.

The memory 14 is used to store one or more programs including instructions and data.
