Abstract
Description
Technical Field
[0001] This invention relates to the field of remote temperature measurement technology, and in particular to a remote temperature measurement method, system and device. Background Technology
[0002] In power line inspection work, it is often necessary to inspect whether there are faults in the lines or electrical equipment. However, some power lines are still installed along rivers, lakes, or in the middle of the country, requiring maintenance personnel to drive boats or other means of transportation to measure the temperature. This leads to problems such as inconvenient transportation and inability to reach the site when inspecting this section of the line.
[0003] Therefore, when inspecting 10kV and 35kV and above power transmission and distribution lines, maintenance personnel usually travel by ordinary boat to inspect the lines. However, the above method requires maintenance personnel to drive the boat for a long time while performing inspection work, which may lead to safety accidents due to improper boat operation.

[0057] This invention provides a remote temperature measurement method, system, and device to address the technical problem that existing technologies require maintenance personnel to operate ships for extended periods while also performing inspection work, which can lead to safety accidents due to improper ship operation.
[0058] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0059] Please see Figure 1 , Figure 1 This is a flowchart illustrating the steps of a remote temperature measurement method provided in Embodiment 1 of the present invention.
[0060] This invention provides a remote temperature measurement method applied to a control system, relating to an unmanned surface vessel (USV). The USV includes a hull 4, a central control system 3, a power system 5, and a temperature measurement device. The method includes the following steps:
[0061] 101. Respond to the received electrical equipment temperature measurement request and obtain the location information of the target electrical equipment corresponding to the electrical equipment temperature measurement request.
[0062] It should be noted that unmanned vessels refer to intelligent vessels that do not require human piloting. The four main components of the hull serve to provide support, facilitate relocation and transportation, and enable operation in complex environments. The entire hull is constructed of waterproof and corrosion-resistant materials, ensuring long-term use in shallow waters, reservoirs, and swamps. The hull is a sealed structure that can be used to store batteries. The central control system 3 controls the start and stop of each module. The central control system 3 can transmit images in real time and download temperature monitoring photos in real time. The temperature measuring device can be a 360° rotatable thermal imaging device, enabling nighttime temperature monitoring, and this device has a zoom function.
[0063] The power system 5 includes a battery, an electric motor, and a propeller. To extend the battery's cycle life, a nickel-metal hydride battery is used as the power source to power the electric motor. The electric motor converts electrical energy into mechanical energy. One end of the electric motor shaft is connected to the propeller. Compared to a traditional internal combustion engine, its advantages include faster power response, higher energy conversion efficiency, and, as a clean energy source, it does not produce exhaust fumes or noise pollution. The target electrical equipment location information refers to the latitude and longitude information corresponding to the target electrical equipment.
[0064] In this embodiment of the invention, after receiving a temperature measurement request from an electrical device, the latitude and longitude information of the target electrical device corresponding to the temperature measurement request is obtained to facilitate subsequent planning of the navigation route.
[0065] 102. Based on environmental information and the location information of the target electrical equipment, plan the target navigation route and determine the starting waypoint information corresponding to the unmanned vessel.
[0066] It should be noted that environmental information includes the environment of the waters where the target electrical equipment is located, including whether it is a reservoir, river, sea, or swamp, the presence of fixed obstacles, and the width and length of the water area. The starting waypoint information refers to the specific address where the unmanned vessel will dock, which can be calculated based on the known environmental information and the location of the target electrical equipment. The target navigation route refers to the shortest route with the fewest obstacles and the fewest turns.
[0067] In this embodiment of the invention, multiple navigation routes are designed by calculating the shortest distance between the coastline or riverbank of the known environmental information and the location of the target electrical equipment. Finally, the optimal route is selected as the target navigation route, and the coastline of the target navigation route is set as the starting point.
[0068] 103. Send the target navigation route to the central control system 3.
[0069] In a specific embodiment, the target navigation route is sent to the central control system 3, which then controls the unmanned vessel's power system 5.
[0070] 104. The central control system 3 controls the power system 5 to drive the hull 4 along the target navigation route to the preset temperature measurement location corresponding to the target electrical equipment location information.
[0071] It should be noted that the optimal temperature measurement distance for the temperature measuring device is within 10 meters. Therefore, the preset temperature measurement location is set in the surrounding area within 10 meters of the target electrical equipment.
[0072] In a specific embodiment, after receiving the target navigation route, the central control system 3 immediately controls the start of the power system 5. The electric motor of the power system 5 converts electrical energy into mechanical energy to drive the hull 4 to travel along the target navigation route until it reaches the surrounding area within 10 meters of the target electrical equipment corresponding to the location information of the target electrical equipment.
[0073] 105. Measure the temperature of the target electrical equipment using temperature measuring equipment and generate equipment temperature information.
[0074] In a specific embodiment, after the temperature measuring device measures the temperature of the target electrical equipment, it reads the measured temperature information and generates equipment temperature information.
[0075] This invention responds to received electrical equipment temperature measurement requests, obtains the location information of the target electrical equipment corresponding to the request, plans a target navigation route based on environmental information and the target electrical equipment location information, and determines the starting waypoint information corresponding to the unmanned surface vessel (USV), sends the target navigation route to the central control system 3, and uses the central control system 3 to control the power system 5 to drive the hull 4 along the target navigation route to the preset temperature measurement location corresponding to the target electrical equipment location information, and uses temperature measuring equipment to measure the temperature of the target electrical equipment and generate equipment temperature information. This solves the technical problem of existing technologies requiring maintenance personnel to operate the vessel for extended periods while also performing inspection work, leading to safety accidents due to improper vessel operation. This invention achieves automatic cruise temperature measurement of electrical equipment installed in waterways in a safe environment by placing a lightweight, easily transportable USV in the water for intelligent cruising, without requiring excessive manpower and resources.
[0076] Please see Figures 2-4 , Figure 2 This is a flowchart illustrating the steps of a remote temperature measurement method provided in Embodiment 2 of the present invention.
[0077] This invention provides a remote temperature measurement method applied to a control system, relating to an unmanned surface vessel (USV). The USV includes a hull 4, a central control system 3, a power system 5, and a temperature measurement device. The method includes the following steps:
[0078] Optionally, the unmanned vessel also includes a detachable device 2, and before step 201, the following steps S11-S12 are also included:
[0079] S11. When a temperature measurement request for electrical equipment is received, determine the unmanned vessel corresponding to the temperature measurement request for electrical equipment;
[0080] S12. Transport the hull 4, detachable equipment 2, central control system 3, power system 5 and temperature measurement equipment corresponding to the unmanned vessel to the starting point and assemble them.
[0081] It should be noted that the electrical equipment temperature measurement request refers to a request for inspection and temperature measurement of electrical equipment; detachable device 2 refers to detachable equipment, which is connected to the hull 4 base via a locking device to prevent accidental detachment due to hull swaying, thus increasing overall stability. The hull 4 base and detachable device 2 can be easily disassembled and transported, and different parts can be replaced according to actual work needs. Detachable device 2 can be considered a multi-functional combination, equipped with infrared thermal imaging, aerial photography, lighting, and other multi-functional integrated equipment. For example, different cameras 1 can be replaced according to actual work needs; a dual-light camera can be used for temperature measurement, and a clearer zoom lens can be used for routine inspections; lighting equipment can be installed to assist operations when visibility is low at night; when a buzzer is added, it can be remotely activated in case of signal loss for easy retrieval; warning lights can be added in foggy weather to alert nearby fishing boats and avoid collision hazards; a loudspeaker can be added for long-distance alerts to on-site personnel. Figures 3-4 As shown, the power system 5’s battery and motor are installed in the base of the hull 4, the paddle is installed at the rear of the base of the hull 4, and the central control system 3, detachable equipment 2 and temperature measuring equipment are installed on the hull 4. The detachable equipment 2 and temperature measuring equipment can be removed for easy transportation.
[0082] In a specific embodiment, when a temperature measurement request for electrical equipment is received, the unmanned surface vessel (USV) to be used is first determined. Various operational data of the USV need to be adjusted to preset values. Specifically, the preset values for the operational data depend on the actual situation and are not limited here. The USV is transported using a pickup truck or a small van cargo box. Before transportation, the hull 4, detachable equipment 2, and temperature measurement equipment need to be disassembled for ease of transport. They are then reassembled upon arrival at the starting point. Compared to the current method of manually inspecting and measuring temperature by boat, this reduces additional costs, such as renting boats and hiring personnel, and also lowers personal safety risks.
[0083] The cost of updating and replacing various equipment functions on unmanned vessels is low. With the replacement of new technologies, equipment and facilities, and the iterative updates of parts, this unmanned vessel needs to replace fixed modules to achieve more functions, effectively reducing the cost of replacing and iterative updates of various equipment and facilities, and achieving a more economical and convenient process.
[0084] 201. Respond to the received electrical equipment temperature measurement request and obtain the location information of the target electrical equipment corresponding to the electrical equipment temperature measurement request.
[0085] In this embodiment of the invention, the specific implementation process of step 201 is similar to that of step 101, and will not be repeated here.
[0086] 202. Based on environmental information and the location information of the target electrical equipment, plan the target navigation route and determine the starting waypoint information corresponding to the unmanned vessel.
[0087] Optionally, a database is involved; step 202 includes the following steps S21-S24:
[0088] S21. Extract environmental information and target electrical equipment location information from the database;
[0089] S22. Based on the outline information of obstacles corresponding to environmental information and the location information of target electrical equipment, plan multiple navigation routes;
[0090] S23. Select the target navigation route from multiple navigation routes according to the preset navigation conditions;
[0091] S24. Determine the docking point corresponding to the target navigation route as the starting point of the unmanned vessel.
[0092] It should be noted that the database is a static database that collects various types of water (sea) data; the preset navigation conditions include, but are not limited to, meeting the safety requirements of the unmanned vessel, such as avoiding collisions with obstacles, minimizing the distance of the navigation route, and minimizing the number of turns.
[0093] In a specific embodiment, by acquiring the outline information of fixed obstacles and the location information of target electrical equipment corresponding to known environmental information, multiple navigation routes are generated in the workspace. The target navigation route is selected according to the safety conditions of the unmanned vessel, namely, it must not collide with obstacles, and the navigation route must have the shortest distance and the fewest turns. The docking point corresponding to the target navigation route is used as the starting point of the unmanned vessel.
[0094] 203. Send the target navigation route to the central control system 3.
[0095] Optionally, the unmanned surface vessel also includes a positioning unit, an inertial measurement unit, and an obstacle sensor; step 203 includes the following steps S31-S36:
[0096] S31. Receive positioning information fed back by the positioning unit in real time;
[0097] S32. Receive real-time feedback from the inertial measurement unit on the ship's speed, heading, and displacement information of hull 4;
[0098] S33. Monitor in real time whether obstacle information is received from the obstacle sensor;
[0099] S34. If not, proceed to the step of real-time monitoring to see if obstacle information is received from the obstacle sensor.
[0100] S35. If so, based on the contour information, navigation speed, heading, and displacement information corresponding to the positioning information and obstacle information, the target navigation route is adjusted using the path planning algorithm and the dynamic obstacle planning algorithm to generate an updated navigation route.
[0101] S36. Send the updated navigation route to the central control system 3.
[0102] It should be noted that the central control system 3 is equipped with a positioning unit, an inertial measurement unit (IMU), and obstacle sensors. The positioning unit provides real-time location information for the unmanned surface vessel (USV) based on its latitude and longitude. The IMU acquires information on the USV's attitude, speed, and directional displacement. The obstacle sensors detect obstacles, and the technologies used for obstacle detection include, but are not limited to, obstacle sensors, ultrasonic technology, infrared lasers, and binocular vision.
[0103] In a specific embodiment, during autonomous cruise, in the first stage, the system detects obstacles, quickly identifies them, and hovers, awaiting further instructions. In the second stage, the system accurately perceives the specific outline of the obstacle using obstacle sensors and then autonomously avoids it. In the third stage, based on the acquired environmental information, the system utilizes an algorithm (considering local hazard avoidance of the unmanned surface vessel in three layers: a known static path planning method based on PSO, a known dynamic path planning method based on PSO and incorporating maritime rules, and an obstacle avoidance method in unknown environments based on a rolling window. The first two layers of algorithms are known local hazard avoidance based on prior environmental knowledge, while the third layer is unknown local hazard avoidance based on sensor knowledge).
[0104] Specifically, 1) Given the static path planning, search for an optimal route from the starting point to the ending point in the workspace. This route must not only meet the safety conditions of the unmanned surface vessel, i.e., it cannot collide with obstacles, but also have the shortest route and the fewest turns.
[0105] 2) Given dynamic path planning, during navigation, there may be overtaking, head-on encounters, and intersections with islands and other ships. In this case, ① avoid known dynamic obstacles within the target segment to achieve the optimal speed and course; ② satisfy international maritime collision avoidance rules; ③ the optimal solution does not intersect with static obstacles.
[0106] 3) Unknown local hazard obstacle avoidance: When obstacle information is undetectable, the unmanned surface vessel (USV) can only perform collision avoidance planning based on real-time detected obstacle information. It employs iterative local optimization planning instead of a one-time global optimization result, fully utilizing the latest local environmental information in each local optimization. When simultaneously implementing real-time obstacle avoidance strategies based on known static and known dynamic paths, it is crucial not only to avoid obstacles nimbly but also to fully consider the globally optimized path to avoid falling into obstacle traps.
[0107] During the cruise, based on positioning information, speed, heading, and displacement information, the unmanned vessel adjusts its heading according to path planning and dynamic obstacle planning algorithms, combined with received instructions. Obstacle sensors perceive obstacles in real time, and the unmanned vessel adjusts its navigation route according to the distance between each point on the route and the obstacles to obtain an updated navigation route. Based on the positioning information, the unmanned vessel arrives at each waypoint as required and performs the corresponding actions, achieving fully autonomous cruise.
[0108] Optionally, the positioning unit includes RTK and GPS; step S31 includes the following steps S311-S313:
[0109] S311. Determine whether the number of satellites has reached the preset satellite number value, whether the ionospheric activity value has reached the preset activity threshold, and whether the network signal has reached the preset network threshold.
[0110] S312. If all conditions are met, the positioning information of hull 4 will be detected in real time via RTK.
[0111] S313. If some or all of the conditions are met, the positioning information of the hull 4 shall be detected in real time by GPS.
[0112] It should be noted that the preset number of satellites is at least 7; the preset activity threshold is set according to the actual VTEC value and is not limited here; the preset network threshold is a medium network signal or a network signal that can transmit information.
[0113] In a specific embodiment, the current operating state of RTK must simultaneously meet three conditions: 1) At least 7 satellites are required for RTK to be fixed, and the number of satellites can be confirmed through the operation panel; 2) When the atmospheric ionospheric activity is high, electromagnetic interference can interfere with satellite positioning, leading to positioning failure. The level of ionospheric activity depends on the vertical total electron content (VTEC). When the overall ionosphere changes slowly, the VTEC value is relatively small, and the positioning service is often better; however, when the ionosphere changes rapidly in time or space, the VTEC value is relatively large, and the positioning performance often deteriorates rapidly. Specifically, the VTEC value at the current moment can be calculated using the Klobuchar model; 3) During RTK fixing, the controller network signal must be normal, which can be achieved by connecting to a mobile hotspot or using a SIM card with normal internet access. When RTK is fixed, it can be viewed on the operating system panel, and RTK can be manually switched on and off and configured through the panel. If the current operating state of RTK does not meet any of the conditions, GPS will detect the positioning information of the hull 4 in real time.
[0114] Specifically, the unmanned surface vessel is equipped with RTK high-precision positioning technology, Global Positioning System (GPS), and Inertial Measurement Unit (IMU), which makes the patrol accuracy more accurate.
[0115] 204. The central control system 3 controls the power system 5 to drive the hull 4 along the target navigation route to the preset temperature measurement location corresponding to the target electrical equipment location information.
[0116] In this embodiment of the invention, the specific implementation process of step 204 is similar to that of step 104, and will not be repeated here.
[0117] 205. Measure the temperature of the target electrical equipment using temperature measuring equipment and generate equipment temperature information.
[0118] It should be noted that the equipment temperature information refers to the measured temperature and the interphase temperature.
[0119] In a specific embodiment, a temperature measuring device is installed on the detachable device 2, which can enable the inspection and temperature measurement of various target electrical devices during the day or night.
[0120] 206. Determine the corresponding temperature risk level based on the temperature threshold range in which the equipment temperature information is located.
[0121] It should be noted that attention should be paid to the heating range of a certain component of the power distribution equipment (75℃ < measured temperature or 10K < phase-to-phase temperature difference). There are three temperature threshold ranges: measured temperature > 90℃ or phase-to-phase temperature difference > 30K; 80℃ < measured temperature ≤ 90℃ or 20K < phase-to-phase temperature difference ≤ 30K; 75℃ < measured temperature ≤ 80℃ or 10K < phase-to-phase temperature difference ≤ 20K.
[0122] In a specific implementation, the maintenance unit analyzes the overheating defects and handles them according to their severity and urgency. The analysis and classification of defects are based on the company's unified defect management guidelines. According to the regulations, (measured temperature > 90℃ or interphase temperature difference > 30K) is classified as urgent; (80℃ < measured temperature ≤ 90℃ or 20K < interphase temperature difference ≤ 30K) is classified as critical; and (75℃ < measured temperature ≤ 80℃ or 10K < interphase temperature difference ≤ 20K) is classified as general.
[0123] 207. Generate and output the corresponding maintenance information according to each temperature risk level.
[0124] In specific embodiments, as stipulated, each temperature risk level has certain maintenance time and maintenance requirements. For example, for an emergency level, maintenance personnel should be dispatched to carry out maintenance within 24 hours and the maintenance information should be sent to the maintenance department or relevant personnel. For a critical level, maintenance personnel should be dispatched to carry out maintenance within 7 days and the maintenance information should be sent to the maintenance department or relevant personnel. For a general level, maintenance personnel should be dispatched to carry out maintenance within 180 days and the maintenance information should be sent to the maintenance department or relevant personnel.
[0125] Optionally, the unmanned vessel also includes a camera 1, and the method further includes the following step S41:
[0126] S41. Capture video of the hull 4 and the environment in which the hull 4 is located using camera 1.
[0127] In a specific embodiment, such as Figures 3-4 As shown, by mounting a camera 1 on the detachable device 2, the camera 1 includes, but is not limited to, a rotatable dual-light camera device (visible light and invisible light), enabling all-weather aerial photography and providing maintenance personnel with comprehensive photos and videos. Specifically, different cameras 1 can be used depending on the actual work; a dual-light camera can be used for temperature measurement, while a clearer zoom lens can be used for routine inspections.
[0128] Optionally, the unmanned surface vessel also includes a brightness sensor, a weather phenomenon instrument, lighting equipment, and warning equipment. The method further includes the following steps S51-S54:
[0129] S51. When the light intensity sensed by the brightness sensor reaches the preset brightness value, brightness information is generated.
[0130] S52. Adjust the lighting equipment according to the brightness information;
[0131] S53. When the visibility detected by the weather phenomenon instrument reaches the preset visibility value, visibility information is generated;
[0132] S54. Activate the warning device based on visibility information.
[0133] It should be noted that both the lighting and warning devices are connected to the detachable device 2. The brightness sensor refers to a sensor that can sense light intensity and convert it into a usable output signal. The weather phenomenon instrument is a meteorological observation system used to observe the weather. It is an intelligent multivariable sensor composed of a scattering visibility meter, a precipitation detection system sensor, and sensors for temperature, humidity, wind direction, and wind speed. It can observe temperature, humidity, wind direction, wind speed, visibility, etc. The preset brightness and preset visibility values are set according to the actual conditions on the water (at sea) and are not limited here.
[0134] In a specific embodiment, when the brightness sensor detects a certain brightness value, it generates brightness information for the current moment and sends it to the central control system 3. Upon receiving this brightness information, the central control system 3 adjusts the lighting equipment. This lighting equipment not only provides illumination at night but also serves as a warning, deterring anyone who might damage electrical equipment.

In cases of poor visibility, it activates warning devices to alert personnel on passing vessels, preventing collisions caused by untimely detection.
