[0027] The high-power charging cable coolant condition monitoring device, method, and equipment provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0028] Example 1

[0029] Figure 1 This is a schematic diagram of the structure of the high-power charging cable coolant condition monitoring device provided in Embodiment 1 of this application. Figure 1 As shown, the specific steps include the following:

[0030] The location identification module 110 is used to identify the location information of sensors set at preset distances; wherein, the sensors are set on a high-power charging cable; the high-power charging cable is provided with a cooling pipe, and the cooling pipe is provided with coolant;

[0031] The working sensor determination module 120 is used to determine the working sensor based on the position information and receive the sensing signal collected by the working sensor.

[0032] The analysis module 130 is used to analyze the sensing signal to determine whether there is a coolant leak. If so, a warning message is generated.

[0033] This application applies to scenarios where sensors are used to determine whether a high-power charging cable has a coolant leak and to generate a warning message. Specifically, the identification of sensor location information, determination of the working sensor, and parsing of the sensed signal can be performed by a smart terminal device. After receiving the warning message, the staff can quickly locate the high-power charging cable with the coolant leak based on the sensor location information and promptly and effectively address the issue.

[0034] Based on the above usage scenarios, it is understood that the executing entity of this application can be the smart terminal device, such as a desktop computer, laptop computer, mobile phone, tablet computer, and interactive multimedia device, etc., without further limitations.

[0035] The position recognition module 110 may consist of sensors and a computer microprocessor chip, and is used to identify the position information of sensors set at preset distances.

[0036] High-power charging cables are cables used to transmit high-power electrical energy, typically used for charging electric vehicles, powering industrial equipment, and other applications requiring high-power charging or supply. Cooling pipes are devices made of metal or plastic with good thermal conductivity. Coolant is a medium used to absorb and remove heat generated by the cable; common coolants include water, cooling oil, and refrigerants.

[0037] The sensor can be a water immersion sensor, which is a modern instrument that determines whether there is water at a location based on the principle of the change in resistance of electrodes when immersed in water.

[0038] The preset distance can be set to different values ​​according to the required detection accuracy, in meters (m), such as 1m, 5m, 10m and 30m.

[0039] Location information can be coordinates (x, y, z) in a spatial Cartesian coordinate system established based on the real-world scene. Location information can be identified by recognizing the signal strength of the radio frequency data emitted by the current sensor at other sensors, analyzing the current sensor's position based on the signal strength, and finally iterating through each sensor on the high-power charging cable to obtain the position information of each sensor.

[0040] The working sensor determination module 120 may consist of a sensor and a computer microprocessor chip, etc., and is used to determine the working sensor based on the position information and receive the sensing signal collected by the working sensor.

[0041] The working sensor can be a water immersion sensor located in a high-power charging cable section where there is a high possibility of coolant leakage, such as a bending section, a contact section, or a torsion section.

[0042] The method for determining the working sensors can be as follows: determine the shape data of the high-power charging cable and determine the bending section based on the location information; determine the shape data of the high-power charging cable and determine the grounding section based on the location information; determine the orientation information of each sensor relative to the high-power charging cable and determine the torsion section based on the location information; and determine the sensors in the bending section, grounding section, and torsion section as the working sensors.

[0043] One method for acquiring sensing signals is to have condensation water contact the water immersion sensor. The sensor's resistance changes due to the water's conduction of electricity, causing the contacts of its built-in relay to close and generate an electrical signal. This generated electrical signal is the sensing signal. Another method for receiving the sensing signal is to use a computer to receive the sensing signal and location information emitted by the water immersion sensor via satellite communication, wireless networks, or wired connections.

[0044] The analysis module 130, which may consist of a computer microprocessor chip, is used to analyze the sensed signals, determine whether there is a coolant leak, and generate warning information.

[0045] One method for analyzing the sensing signals is to use a computer to record the time points when the working sensor emits sensing signals. If the time points when the working sensor emits sensing signals are continuous or periodic, it indicates that there is a coolant leakage problem.

[0046] Warning messages can be used to alert staff to address coolant leaks in high-power charging cables. These messages may include the location of the sensor emitting the warning signal, the severity of the coolant leak, and appropriate corrective measures. The severity of the coolant leak can be determined by the timing of the sensor's warning signals. Generally, continuous warning signals indicate the highest severity, requiring immediate attention. Periodic warning signals, with longer periods or higher frequencies, also indicate greater severity.

[0047] The warning message can be generated by displaying a pop-up warning window on the smart terminal's screen. This window displays a warning icon, the location information of the sensor emitting the sensing signal, the severity of the coolant leak, and corresponding handling measures. The smart terminal's speaker plays a warning audio. The location information of the sensor emitting the sensing signal can be displayed either by directly showing the spatial coordinates in text form, or by plotting the aforementioned spatial Cartesian coordinate system based on the real-world scenario, and marking the spatial coordinate points of the sensor emitting the sensing signal in red on the graph.

[0048] Optionally, the device further includes:

[0049] The sensor fault detection module is used to obtain the sensor ID of the current sensor when the sensing data of the current sensor and the adjacent sensors do not conform to the coolant leakage pattern; and to generate sensor maintenance information based on the sensor ID.

[0050] The coolant leakage pattern can be identified as coolant flowing from a higher-level section of the high-power charging cable to a lower-level section. To determine if the sensing data conforms to this pattern, the position information of the current sensor and adjacent sensors can be obtained. If the z-value in the current sensor's position information (x, y, z) is greater than or equal to the z-value of the adjacent sensor, and the current sensor has emitted sensing data while the adjacent sensor has not, then the sensing data does not conform to the coolant leakage pattern, and the adjacent sensor is identified as having a problem. Alternatively, if the z-value in the current sensor's position information (x, y, z) is less than the z-value of the adjacent sensor, and the current sensor has not emitted sensing data while the adjacent sensor has, then the sensing data does not conform to the coolant leakage pattern, and the current sensor is identified as having a problem.

[0051] A sensor ID can be the sequential number of the sensors mounted on a high-power charging cable, running from one end to the other, such as 001, 002, 003, etc. The sensor ID can be obtained by sending its current sensor ID to the computer if a problem is detected with the current sensor, or by sending its current sensor ID-1 (with the adjacent sensor listed first) or current sensor ID+1 (with the adjacent sensor listed last) to the computer if a problem is detected with a neighboring sensor. The sensor ID can be sent via satellite communication, wireless network, or wired connection.

[0052] Sensor maintenance information can be used to prompt staff to inspect and repair faulty sensors. This information can be generated by a pop-up maintenance window on a smart terminal's display, showing a maintenance icon and the sensor ID.

[0053] The advantage of this device is that by identifying problematic sensors based on the sensing data of the current sensor and adjacent sensors, as well as the coolant leakage pattern, and generating sensor maintenance information, it can help staff to promptly detect faulty sensors. This prevents malfunctioning sensors from affecting the coolant leakage detection results and causing staff to fail to detect coolant leakage problems in a timely manner.

[0054] In this application example, a location identification module is used to identify the location information of sensors set at preset distances; wherein, the sensors are installed on a high-power charging cable; the high-power charging cable is equipped with a cooling pipe, and the cooling pipe contains coolant; a working sensor determination module is used to determine the working sensor based on the location information and receive the sensing signals collected by the working sensor; an analysis module is used to analyze the sensing signals to determine whether there is a coolant leakage problem, and if so, generate a warning message. This technical solution, by identifying the sections of the high-power charging cable that are more prone to coolant leakage problems and receiving the sensing signals from the sensors in the aforementioned sections, can reduce the amount of data that needs to be collected and analyzed, improve monitoring efficiency, and improve the operational safety of the high-power charging pile cable by analyzing the sensing signals to determine whether there is a coolant leakage problem.

[0055] Example 2

[0056] Figure 2 This is a schematic diagram of the high-power charging cable coolant status monitoring device provided in Embodiment 2 of this application. This solution makes further improvements based on the above embodiments, specifically: the position identification module is used to: identify the signal strength of the radio frequency data emitted by the current sensor at other sensors; wherein, the other sensors include a base sensor disposed at the base of the charging device; analyze the position of the current sensor based on the signal strength to obtain the position information of the current sensor; and traverse each sensor on the high-power charging cable to obtain the position information of each sensor.

[0057] like Figure 2 As shown, the device includes:

[0058] The position recognition module 210 may consist of sensors and a computer microprocessor chip, and is used to identify the position information of sensors set at preset distances.

[0059] The working sensor determination module 220 may consist of a sensor and a computer microprocessor chip, etc., and is used to determine the working sensor based on the position information and receive the sensing signal collected by the working sensor.

[0060] The analysis module 230, which may consist of a computer microprocessor chip, is used to analyze the sensed signals, determine whether there is a coolant leak, and generate warning information.

[0061] Specifically, the location identification module 210 is used to: identify the signal strength of the radio frequency data emitted by the current sensor at other sensors; wherein the other sensors include a base sensor disposed at the base of the charging device; analyze the location of the current sensor according to the signal strength to obtain the location information of the current sensor; and traverse each sensor on the high-power charging cable to obtain the location information of each sensor.

[0062] The charging device base can be a stand or bracket used to support and fix the charging device. The base sensor can be an electromagnetic wave sensor used to obtain position information of each sensor. The electromagnetic wave sensor can be a device used to detect and measure electromagnetic fields and electromagnetic waves.

[0063] Radio frequency (RF) data can be electromagnetic wave signals. Signal strength can be the energy or power level of an electromagnetic wave propagating through space, measured in watts per square meter (W / m²). 2 Signal strength can be measured in decibels (dB) or 1000 kilometres (dB). One method for identifying signal strength is to use a base sensor to receive the electromagnetic waves emitted by the current sensor and analyze and calculate the intensity of the electromagnetic waves.

[0064] The location resolution method involves using a base sensor to identify the electromagnetic signal strength of adjacent base sensors, and then using both base sensors to identify the electromagnetic signal strength of the current sensor. Based on these electromagnetic signals and the position information and distance between the two base sensors, the current sensor's position information is calculated using trigonometric functions. The position information and distance between the two base sensors can be known data.

[0065] The advantage of this technical solution is that by obtaining the position information of each sensor based on the signal strength of the radio frequency data emitted by each sensor at the base sensor, the staff does not need to measure the position information of each sensor on-site, thus improving the detection efficiency.

[0066] Example 3

[0067] Figure 3 This is a schematic diagram of the high-power charging cable coolant condition monitoring device provided in Embodiment 3 of this application. This solution makes further improvements based on the above embodiments, specifically: the working sensor determination module is used to: determine the morphological data of the high-power charging cable based on the position information; input the morphological data into a pre-set bending degree detection model to determine the bending section of the high-power charging cable; and determine the sensor within the bending section as the working sensor.

[0068] like Figure 3 As shown, the device includes:

[0069] The position recognition module 310 may consist of sensors and a computer microprocessor chip, and is used to identify the position information of sensors set at preset distances.

[0070] The working sensor determination module 320 may consist of a sensor and a computer microprocessor chip, etc., and is used to determine the working sensor based on the position information and receive the sensing signal collected by the working sensor.

[0071] The analysis module 330, which may consist of a computer microprocessor chip, is used to analyze the sensed signals, determine whether there is a coolant leak, and generate warning information.

[0072] Specifically, the location identification module 310 is used to: identify the signal strength of the radio frequency data emitted by the current sensor at other sensors; wherein the other sensors include a base sensor disposed at the base of the charging device; analyze the location of the current sensor according to the signal strength to obtain the location information of the current sensor; and traverse each sensor on the high-power charging cable to obtain the location information of each sensor.

[0073] Specifically, the working sensor determination module 320 is used to: determine the shape data of the high-power charging cable based on the position information; input the shape data into a pre-set bending degree detection model to determine the bending section of the high-power charging cable; and determine the sensor in the bending section as the working sensor.

[0074] One method for determining the morphological data is to establish a spatial Cartesian coordinate system based on the real-world scenario, with the horizontal ground as the xoy plane. Within this coordinate system, the positional information of each sensor is marked. Interpolation is then used to fit these marked points into a smooth curve, thereby determining the morphological data of the high-power charging cable. Interpolation can be a numerical analysis method used to estimate values ​​between discrete data points by constructing a continuous function. Common interpolation methods include linear interpolation, polynomial interpolation, spline interpolation, Kriging interpolation, and radial basis function interpolation.

[0075] The algorithm for the bending degree detection model can be as follows: on the smooth curve mentioned above, mark points at regular intervals, connect the previous mark point with the current mark point with a straight line, and connect the next mark point with the current mark point with a straight line. Calculate the angle between the two straight lines. If the angle is greater than 15°, then the cable segment corresponding to the curve segment between the previous mark point and the next mark point is determined as the bending segment. Traverse each mark point on the smooth curve to obtain all bending segments on the high-power charging cable.

[0076] One way to determine which sensor is active is to define a Boolean data variable for each sensor with an initial value of "false". The computer then changes the value of the Boolean data variable for sensors located within the bending section to "true". Specifically, these data variables represent whether the current sensor is active; a value of "true" indicates yes, and a value of "false" indicates no.

[0077] The advantage of this technical solution is that by using the shape data of the high-power charging cable and the pre-set bending degree detection model, the sensors in the bending section are identified as working sensors. This allows for the collection of sensing signals only in sections prone to coolant leakage, reducing the amount of data and improving detection efficiency.

[0078] Example 4

[0079] Figure 4 This is a schematic diagram of the high-power charging cable coolant condition monitoring device provided in Embodiment 4 of this application. This solution makes a further improvement on Embodiment 2, specifically: the working sensor determination module is used to: determine the morphological data of the high-power charging cable based on the location information; input the morphological data into a pre-set grounding detection model to determine the grounding section of the high-power charging cable; and determine the sensors within the grounding section as working sensors.

[0080] like Figure 4 As shown, the device includes:

[0081] The position recognition module 410 may consist of sensors and a computer microprocessor chip, and is used to identify the position information of sensors set at preset distances.

[0082] The working sensor determination module 420 may consist of a sensor and a computer microprocessor chip, etc., and is used to determine the working sensor based on the position information and receive the sensing signal collected by the working sensor.

[0083] The analysis module 430, which may consist of a computer microprocessor chip, is used to analyze the sensed signals, determine whether there is a coolant leak, and generate warning information.

[0084] Specifically, the location identification module 410 is used to: identify the signal strength of the radio frequency data emitted by the current sensor at other sensors; wherein the other sensors include a base sensor disposed at the base of the charging device; analyze the location of the current sensor according to the signal strength to obtain the location information of the current sensor; and traverse each sensor on the high-power charging cable to obtain the location information of each sensor.

[0085] Specifically, the working sensor determination module 420 is used to: determine the shape data of the high-power charging cable based on the location information; input the shape data into a pre-set grounding detection model to determine the grounding section of the high-power charging cable; and determine the sensor in the grounding section as the working sensor.

[0086] The algorithm for grounding detection models can be to extract the coordinate z-values ​​of each point on a smooth curve, and determine the cable section corresponding to the curve segment with a z-value less than 50 cm as the grounding section.

[0087] One way to determine if a sensor is operational is to define a Boolean data variable for each sensor with an initial value of "false". The computer then changes the value of the Boolean data variable for the sensors located within the contact area to "true". Specifically, this data variable represents whether the current sensor is operational; a value of "true" indicates yes, and a value of "false" indicates no.

[0088] The advantage of this technical solution is that by using the morphological data of the high-power charging cable and the grounding detection model, the sensors in the grounding section are identified as working sensors. This allows for the collection of sensing signals only in sections prone to coolant leakage, reducing the amount of data and improving detection efficiency.

[0089] Example 5

[0090] Figure 5 This is a schematic diagram of the structure of the high-power charging cable coolant condition monitoring device provided in Embodiment 5 of this application. This solution makes a further improvement on Embodiment 2, specifically: the working sensor determination module is used to: determine the orientation information of each sensor relative to the high-power charging cable based on the position information; input the orientation information into a pre-set morphological detection model to determine the torsion section of the high-power charging cable; and determine the sensors within the torsion section as working sensors.

[0091] like Figure 5 As shown, the device includes:

[0092] The position recognition module 510 may consist of sensors and a computer microprocessor chip, and is used to identify the position information of sensors set at preset distances.

[0093] The working sensor determination module 520 may consist of a sensor and a computer microprocessor chip, etc., and is used to determine the working sensor based on the position information and receive the sensing signal collected by the working sensor.

[0094] The analysis module 530, which may consist of a computer microprocessor chip, is used to analyze the sensed signals, determine whether there is a coolant leak, and generate warning information.

[0095] Specifically, the location identification module 510 is used to: identify the signal strength of the radio frequency data emitted by the current sensor at other sensors; wherein the other sensors include a base sensor disposed at the base of the charging device; analyze the location of the current sensor according to the signal strength to obtain the location information of the current sensor; and traverse each sensor on the high-power charging cable to obtain the location information of each sensor.

[0096] The working sensor determination module 520 is specifically used for: determining the orientation information of each sensor relative to the high-power charging cable based on the position information; inputting the orientation information into a pre-set shape detection model to determine the torsion section of the high-power charging cable; and determining the sensors in the torsion section as working sensors.

[0097] Orientation information can be the angle of the sensor relative to the vertical direction of the high-power charging cable axis. Orientation information can be determined by adding a tiny accelerometer chip to the sensor. The accelerometer chip measures the tilt angle of the sensor, and the obtained tilt angle is the orientation information. Specifically, when the sensor tilts, under the influence of gravity or acceleration, the mass block in the accelerometer chip causes a voltage change in the sensing electrodes, thereby measuring the tilt angle.

[0098] The algorithmic idea of ​​the shape detection model can be to define the cable section between sensors with continuous orientation information greater than 15° as the torsion section.

[0099] One method to determine the functioning sensor is to define a Boolean data variable for each sensor with an initial value of "false". The computer then changes the value of the Boolean data variable for the sensor located within the torsion section to "true". Specifically, this data variable represents whether the current sensor is functioning; a value of "true" indicates yes, and a value of "false" indicates no.

[0100] The advantage of this technical solution is that by using the orientation information of the high-power charging cable and the pre-set morphological detection model, the sensors in the torsion section are identified as working sensors. This allows for the collection of sensing signals only in sections prone to coolant leakage, reducing the amount of data and improving detection efficiency.

[0101] Example 6

[0102] Figure 6 This is a flowchart illustrating the high-power charging cable coolant condition monitoring method provided in Embodiment Six of this application. Figure 6 As shown, the specific steps include the following:

[0103] S601. The position information of the sensors set at preset distances is identified by the position recognition module; wherein the sensors are set on a high-power charging cable; the high-power charging cable is provided with a cooling pipe, and the cooling pipe is provided with coolant;

[0104] S602. The working sensor determination module determines the working sensor based on the position information and receives the sensing signal collected by the working sensor.

[0105] S603. The sensing signal is analyzed by the analysis module to determine whether there is a coolant leak. If so, a warning message is generated.

[0106] In this embodiment, a location identification module identifies the location information of sensors set at preset distances. These sensors are mounted on a high-power charging cable, which has a cooling pipe containing coolant. A working sensor determination module identifies the working sensor based on the location information and receives the sensing signals collected by the working sensor. A parsing module analyzes the sensing signals to determine if coolant leakage exists; if so, a warning message is generated. This high-power charging cable coolant status monitoring method, by identifying sections of the high-power charging cable prone to coolant leakage and receiving sensing signals from sensors within those sections, reduces the amount of data collected and analyzed, improving monitoring efficiency.
