Abstract
Description
Technical Field
[0001] This utility model relates to the field of power systems, specifically to a real-time monitoring device for transmission lines. Background Technology
[0002] With the expansion and increasing complexity of power grids, the safe operation of transmission lines faces severe challenges. Traditional manual inspection methods rely on maintenance personnel conducting regular on-site surveys, which suffer from low efficiency, high risk, and poor real-time performance, making it difficult to meet the needs of modern intelligent power grid management. In recent years, Internet of Things (IoT)-based transmission line monitoring devices have become increasingly widespread.
[0003] However, current power transmission line monitoring devices generally suffer from the following technical defects:
[0004] 1. Limited functionality: Traditional equipment only supports a single monitoring function (such as ice accumulation or wildfire monitoring), requiring the deployment of multiple devices to cover different scenarios, resulting in high costs and complex operation and maintenance;
[0005] 2. Upgrade limitations: Device firmware updates rely on factory returns, making it impossible to remotely expand new functions and difficult to adapt to dynamic monitoring needs;
[0006] 3. Poor sensor compatibility: Most devices use closed interfaces, which only support sensors from specific manufacturers, limiting their expandability. Utility Model Content
[0007] The purpose of this invention is to provide a real-time monitoring device for power transmission lines to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A real-time monitoring device for power transmission lines includes a main body with several PCBA board slots arranged in a straight line. Below each PCBA board slot, from left to right, are a first sensor interface, an infrared camera interface, a current transformer interface, and a second sensor interface. The main body contains a main control unit, which includes a processor and a memory. The memory is electrically connected to the processor, and the processor is electrically connected to the PCBA board slots, the first sensor interface, the infrared camera interface, the current transformer interface, and the second sensor interface.
[0010] In one possible implementation, an antenna interface is provided on the left side of the first sensor interface, and the antenna interface is electrically connected to the processor.
[0011] In one possible implementation, the first sensor interface is an RS-485 interface.
[0012] In one possible implementation, the second sensor interface adopts a GPIO general-purpose input / output interface.
[0013] In one possible implementation, the PCBA board slot uses a PCIe interface.
[0014] In one possible implementation, the infrared camera interface uses a gigabit Ethernet interface.
[0015] In one possible implementation, the transformer interface is a current transformer interface.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. Different PCBA boards can be installed on the monitoring unit according to different needs to meet the requirements of the monitoring project;
[0018] 2. Through multiple sensor and transformer interfaces, different sensors can be flexibly equipped, which facilitates decoupling with different PCBA boards and achieves the purpose of rapid analysis and monitoring of monitoring items;
[0019] 3. Supports OTA upgrades through communication interfaces. The processor can intelligently identify the plugged PCBA boards. Combined with dynamic loading algorithms and sensor drivers, it effectively reduces operation and maintenance costs. Attached Figure Description
[0020] Figure 1 This is a schematic diagram of the overall structure of this utility model. Detailed Implementation
[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0022] This invention utilizes multiple different interfaces on the main body. The processor only needs to intelligently identify the data type and then assign the task to different interfaces for processing. Each interface is connected to a corresponding sensor or functional module. The functional module uses its carried model or algorithm to process the data, thereby realizing the function of intelligent monitoring of power transmission lines.
[0023] The following is combined Figure 1 The structure of this utility model will be described in detail below. For example... Figure 1As shown, a real-time monitoring device for power transmission lines includes: a main body 100, on the upper surface of which are provided multiple PCBA board slots 200 arranged in a straight line; below each PCBA board slot 200, from left to right, are arranged multiple interfaces, namely: a first sensor interface 310, an infrared camera interface 320, a current transformer interface 330, and a second sensor interface 340; the main body 100 integrates a main control unit 400, which includes a processor 410 and a memory 420, the memory 420 being electrically connected to the processor 410; wherein, the processor 410 establishes electrical connections with the PCBA board slots 200, the first sensor interface 310, the infrared camera interface 320, the current transformer interface 330, and the second sensor interface 340 respectively. An antenna interface 350 is provided on the left side of the first sensor interface 310, and the antenna interface 350 is electrically connected to the processor 410.
[0024] The first sensor interface 310 adopts the RS-485 standard interface and supports the Modbus communication protocol. The second sensor interface 340 adopts the GPIO general-purpose input / output interface and can be configured with opto-isolation circuitry. The PCBA board slot 200 adopts the PCIe 3.0 x4 interface specification and supports hot-swapping. The infrared camera interface 320 adopts a Gigabit Ethernet interface and supports the PoE power supply protocol. The current transformer interface 330 is a dedicated interface for current transformers, including ±5V differential signal input terminals. The processor 410 adopts an ARM architecture. The memory uses LPDDR4 RAM + eMMC storage, mainly used for caching sensor data. Similar processors and memory can also be used for data processing and storage.
[0025] The following explanation describes the function of each PCBA board slot in a scenario with four slots. Each PCBA board slot is used for hot-swapping different PCBA boards. The specific functions of each PCBA board are as follows:
[0026] The core functions of the icing monitoring module are to perform LSTM icing prediction model and BeiDou short message communication, and to work with sensors with RS-485 interfaces, such as connecting a tension sensor to the RS-485 interface.
[0027] The core functions of the ground fault module are to perform wavelet transform localization algorithm and transient waveform recording control, and to cooperate with the current transformer.
[0028] The core function of the wildfire identification module is to use a lightweight YOLOv5 model and gas detection algorithm in conjunction with an infrared camera to identify wildfires.
[0029] Other modules can be configured according to requirements.
[0030] PCBA board slots can be added to the main body according to actual needs to be used for inserting different PCBA board modules. In this utility model, the number of PCBA board slots is not particularly limited.
[0031] In operation, data is first acquired from sensors connected to the first and second sensor interfaces, with the main control unit efficiently receiving multiple data streams via DMA technology. The main control unit then classifies the data and sends it to the corresponding PCBA boards. Finally, the data is processed using models or algorithms integrated on the PCBA boards, and the processing results are transmitted to the cloud via a communication module connected to the antenna interface. The main control unit can intelligently allocate load based on the operational status of modules connected to each interface, monitor computing power load in real time, and automatically pause low-priority tasks in emergency scenarios (such as wildfires).
[0032] Through the structural design of this invention, the PCBA board only integrates the algorithm, while external sensors are independently connected via standardized interfaces, supporting plug-and-play functionality across different vendors' devices. When replacing a camera, only the PCBA board driver needs to be updated; no modification to the main control program is required. Equipped with an antenna interface 350, it can receive data from the cloud and perform OTA upgrades, enabling the device to perform intelligent monitoring and configuration based on real-time needs.
