Description

Technical Field

[0001] This invention relates to the field of communication modules, and in particular to a battery management method and system for a 4G communication module of a temperature control device based on a cloud platform. Background Technology

[0002] A 4G communication module refers to a module that connects to temperature control equipment and enables remote uploading of temperature control data and downlink transmission of control commands, thereby giving the temperature control equipment the ability to perform wireless remote monitoring and management.

[0003] In the existing technology, the temperature control device communicates with the cloud platform through a 4G communication module. The 4G communication module is powered by the temperature control device. The temperature control device and the 4G communication module need to be powered on before leaving the factory. After the test is completed, the temperature control device will be powered off. After the power off of the temperature control device is detected, the 4G communication module switches to the backup battery for power supply.

[0004] When the power-on test of the 4G communication module is completed and it enters the warehousing and transportation stage, the 4G communication module continues to be powered by the backup battery, which leads to excessive power consumption of the 4G communication module during the warehousing and transportation process. Summary of the Invention

[0005] To reduce the situation where the backup battery of a 4G communication module is completely depleted, this invention provides a method and system for managing the battery of a 4G communication module in a temperature control device based on a cloud platform.

[0006] In a first aspect, the present invention provides a battery management method for a 4G communication module of a temperature control device based on a cloud platform, employing the following technical solution: A cloud-based method for battery management of 4G communication modules in temperature control devices includes: Step 100: In response to the preset direct supply signal, the power supply current is collected. The direct supply signal refers to the signal when the temperature control device supplies power to the 4G communication module, and the power supply current refers to the magnitude of the current when the temperature control device supplies power to the 4G communication module. Step 101: Identify the power failure characteristic from the power supply current. The power failure characteristic refers to the signal that the temperature control device stops supplying power to the 4G communication module. Step 102: Retrieve backup permission in response to power failure feature. Backup permission refers to the user's permission for the use status of backup battery. Step 103: When the backup permission is consistent with the preset availability state, a backup power supply command is generated and sent based on the preset backup circuit. The availability state refers to the permission to enable the backup battery, and the backup power supply command refers to the command to control the backup battery to supply power to the 4G communication module through the backup circuit.

[0007] Step 104: When the backup license is consistent with the preset availability status, collect the communication data sent by the communication module. The communication data refers to the data stream transmitted by the 4G communication module received from the cloud platform. Step 105: Determine the data content based on the communication data. The data content refers to the actual meaning represented by the communication data. Step 106: If the data content is consistent with the preset default data, then determine the default duration in response to the data content. The default duration refers to the duration of the 4G communication module disconnection. Step 107: When the default duration exceeds the preset default threshold, generate and send a backup shutdown command based on the default duration. The backup shutdown command is the command to turn off the backup battery.

[0008] By adopting the above technical solution, the 4G communication module monitors the power supply of the temperature control device to the 4G communication module in real time. When it is detected that the temperature control device has stopped supplying power to the 4G communication module, the backup permission in the instruction record is called and the backup permission is compared with the available status to determine whether the user allows the 4G communication module to call the backup battery. When the two are consistent, the backup battery is allowed to be activated, reducing the situation where the 4G communication module calls the backup battery when the user does not allow it, and reducing the situation where the backup battery is exhausted during warehousing and transportation.

[0009] With the backup battery enabled, the cloud platform collects communication data sent by the 4G communication module and compares the data text content with the default data when the 4G communication module is not connected to the temperature control device. When the two match, the default duration is recorded. If the default duration is too long, it is determined that the connection between the 4G communication module and the temperature control device is interrupted. At this time, the backup battery stops supplying power to the 4G communication module, reducing the unnecessary power consumption of the backup battery and reducing the possibility of the backup battery being completely depleted when the 4G communication module is disconnected from the device.

[0010] Optional, also includes: Step 108: When the default duration is not greater than the preset default threshold, analyze the data type based on the data content; Step 109: Analyze the association type based on data type; Step 110: Select the calculated data according to the data type, and obtain the associated data based on the calculated data and the association type; Step 111: Analyze and calculate the correlation data to obtain theoretical data; Step 112: Compare the calculated data with the theoretical data to determine the deviation data; Step 113: If the deviation data exceeds the preset allowable range, determine the distortion ratio based on the deviation data and data content; Step 114: When the distortion ratio is greater than the preset distortion threshold, generate and send a backup shutdown command based on the distortion ratio.

[0011] By adopting the above technical solution, when the default duration is not too long, the data text content is analyzed to determine the data category, and data that is directly related to the data category is selected as associated data. Theoretical data is then calculated based on the associated data and compared with the actual calculated data. When the deviation between the two is too large, the distortion ratio is calculated based on the deviation data. When the distortion ratio is too large, the backup battery is stopped from supplying power to the 4G communication module, reducing the ineffective power consumption of the backup battery of the 4G communication module and reducing the situation where the backup battery is completely consumed when the 4G communication module data is distorted.

[0012] Optional, also includes: Step 115: When the distortion ratio is greater than the preset distortion threshold, determine the actual signal strength based on the communication data; Step 116: Determine the intensity difference curve based on the actual signal strength and the preset reference strength; Step 117: Determine the equipment vibration curve in response to the intensity difference curve; Step 118: Determine the maximum amplitude based on the equipment vibration curve; Step 119: When the maximum amplitude is greater than the preset amplitude threshold, generate and send a backup shutdown command based on the maximum amplitude.

[0013] By adopting the above technical solution, when the data distortion ratio is too large, the signal strength at each time point is obtained through the communication data between the 4G communication module and the cloud platform, and the equipment vibration curve reflecting the equipment vibration is obtained according to the corresponding relationship. The maximum amplitude of the equipment is read from the equipment vibration curve, so that when the maximum amplitude is too large, it is determined that the operating state of the 4G communication module is not stable enough, and then the backup battery is stopped from supplying power to the 4G communication module, reducing the ineffective power consumption of the backup battery of the 4G communication module and reducing the situation where the backup battery is completely consumed when the 4G communication module is in a vibration environment.

[0014] Optionally, it also includes a connection analysis method, which further includes: Step 200: When the maximum amplitude is greater than the preset amplitude threshold, combine the communication data and the preset time window to extract window data; Step 201: Calculate the disconnection rate based on window data; Step 202: Determine the disconnection trend in response to the disconnection ratio, and retrieve the number of times the backup battery has been activated; Step 203: Determine the probability of disconnection by combining the number of times the connection is activated and the disconnection trend; Step 204: When the loosening probability is greater than the preset loosening threshold, generate and send a backup shutdown command based on the loosening probability.

[0015] By adopting the above technical solution, when the maximum amplitude is too large, communication data is intercepted according to the time window and the number of signal disconnections within different time windows is analyzed. The disconnection ratio is obtained based on the number of signal disconnections and arranged in chronological order to predict the growth rate of the disconnection ratio. Combined with the number of times the backup battery is activated, the probability of the 4G communication module detaching from the temperature control device is determined. Thus, when the connection between the 4G communication module and the temperature control device is unreliable, the backup battery's power supply to the 4G communication module is stopped, reducing the ineffective power consumption of the 4G communication module's backup battery and reducing the situation where the backup battery is completely consumed when the 4G communication module is in a detached state.

[0016] Optionally, connectivity analysis methods also include: Step 205: When the probability of loosening is greater than the preset loosening threshold, determine the vibration direction based on the number of activations and the disconnection ratio; Step 206: Determine the vibration timing based on the vibration orientation; Step 207: Analyze the vibration timing sequence to determine the vibration direction; Step 208: Determine the location of vibration based on the direction of vibration; Step 209: Generate and display vibration warnings based on the vibration location.

[0017] By adopting the above technical solution, when the connection between the 4G communication module and the temperature control equipment is unreliable, the vibration location of the 4G communication module being loosened is determined according to the number of times it is activated and the proportion of disconnections. The vibration location is then arranged according to time to obtain the vibration sequence. Based on the vibration sequence, vibration propagation is simulated to infer the vibration direction, thereby inferring the location of vibration on the temperature control equipment and reminding staff to handle it in a timely manner, thus improving the stability of the 4G communication module working in a vibration environment.

[0018] Optionally, connectivity analysis methods also include: Step 210: When the probability of detachment is greater than the preset detachment threshold, determine the predicted signal strength based on the number of activations; Step 211: Compare the predicted signal strength with the actual signal strength to determine the strength deviation, and retrieve historical data; Step 212: Identify disconnected nodes from historical data; Step 213: Calculate the signal strength fluctuation before and after the disconnection node; Step 214: Determine the drop height of the communication module in response to fluctuation values; Step 215: Determine the fall deviation of the communication module based on the fall height; Step 216: When the strength deviation is not greater than the drop deviation, determine the specific damaged parts by combining the strength deviation and the drop height; Step 217: Generate and display component damage warnings based on damaged components.

[0019] By adopting the above technical solution, when the probability of detachment is too high, the theoretical signal strength is calculated based on the number of times the backup battery has been activated. The difference between the theoretical signal strength and the actual signal strength is calculated as the strength deviation. At the same time, historical communication data before and after the 4G communication module is dropped is retrieved and analyzed to determine the drop height of the 4G communication module, thereby predicting the maximum drop deviation of the 4G communication module at the drop height. If the strength deviation is less than the drop deviation, it means that the signal fluctuation is caused by damage to the 4G communication module. At this time, the drop height and strength deviation are analyzed to determine the actual damaged component, and the staff is reminded to deal with it in time, thereby improving the reliability of the 4G communication module operation.

[0020] Optionally, connectivity analysis methods also include: Step 218: When the strength deviation is less than the drop deviation, determine the degree of damage based on the drop height; Step 219: Determine component deviations based on the degree of damage; Step 220: Determine the deviation value by combining component deviation and strength deviation; Step 221: If the deviation value exceeds the preset deviation threshold, generate an impact force distribution map based on the component deviation and strength deviation; Step 222: Determine the number of impacts based on the impact force distribution map; Step 223: When the number of impacts is not greater than the preset impact threshold, generate and display a component damage warning based on the impact force distribution map.

[0021] By adopting the above technical solution, when the probability of loosening is too high, the impact force distribution map under different possible component damage is simulated based on component deviation and strength deviation. Thus, when the number of impact points in the impact force distribution map is too large, it is determined that the situation does not conform to reality, thereby filtering out the corresponding possible component damage and improving the accuracy of damage identification.

[0022] Optionally, the method for generating the impact force distribution map also includes: Step 300: Determine the weight of each component based on the component deviation and strength deviation, and obtain the combination of damaged weights; Step 301: Extract the weight degree from the damaged weight combination; Step 302: Determine the impact intensity based on the weighting degree, and extract the weight position from the damaged weight combination; Step 303: Generate an impact force distribution map by combining the impact intensity and weighted location.

[0023] By adopting the above technical solution, the deviations of each component are weighted and combined to obtain the damage weight combination under different possible component damage corresponding to the strength deviation. The impact force of the component when falling is matched according to the weight degree of damage of different components, and the impact force is matched with the weight position of the corresponding component to form an impact force distribution map, thereby improving the accuracy of damage identification.

[0024] Secondly, this application provides a cloud-based battery management system for a 4G communication module of a temperature control device: A cloud-based temperature control device 4G communication module battery management system includes: The acquisition module is used to acquire the power supply current. The memory is used to store the program of any of the above-mentioned cloud-based temperature control device 4G communication module battery management methods; By adopting the above technical solution, the 4G communication module monitors the power supply of the temperature control device to the 4G communication module in real time. When it is detected that the temperature control device has stopped supplying power to the 4G communication module, the backup license in the instruction record is called. The backup license is adjusted by the user through the cloud platform and compared with the available status. When the two are consistent, the backup battery is allowed to be activated.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The 4G communication module monitors the power supply of the temperature control device to the 4G communication module in real time. When it is detected that the temperature control device has stopped supplying power to the 4G communication module, it calls the backup permission in the instruction record and compares the backup permission with the available status to determine whether the user allows the 4G communication module to call the backup battery. When the two are consistent, the backup battery is allowed to be activated, reducing the situation where the 4G communication module calls the backup battery when the user does not allow it, and reducing the situation where the backup battery is exhausted during warehousing and transportation. When the maximum amplitude is too large, communication data is captured according to the time window and the number of signal disconnections in different time windows is analyzed. The disconnection ratio is obtained based on the number of signal disconnections and arranged in chronological order to predict the growth rate of the disconnection ratio. Combined with the number of times the backup battery is activated, the probability of the 4G communication module detaching from the temperature control device is determined. Thus, when the connection between the 4G communication module and the temperature control device is unreliable, the backup battery power supply to the 4G communication module is stopped, reducing the ineffective power consumption of the backup battery of the 4G communication module and reducing the situation where the backup battery is completely consumed when the 4G communication module is in a detached state. By weighting and combining the deviations of each component, the damage weight combination corresponding to different possible component damage is obtained. The impact force received by the component during the fall is matched according to the weight degree of damage of different components, and the impact force is matched with the weight position of the corresponding component to form an impact force distribution map, thereby improving the accuracy of damage identification.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] This application discloses a method and system for battery management of a 4G communication module in a temperature control device based on a cloud platform.

[0029] Reference Figure 1 The battery management method for 4G communication modules in cloud-based temperature control devices includes: Step 100: Acquire the power supply current in response to the preset direct supply signal.

[0030] The direct supply signal refers to the signal when the temperature control device supplies power to the 4G communication module. When the current sensor in the 4G communication module senses the power supply from the temperature control device, it determines to generate the direct supply signal. The method for generating the direct supply signal is common knowledge to those skilled in the art.

[0031] The power supply current refers to the magnitude of the current when the temperature control equipment supplies power to the 4G communication module. The current value is collected by the current sensor in the 4G communication module as the power supply current, and is determined by the staff based on the actual situation.

[0032] Step 101: Identify the power outage characteristics from the supply current.

[0033] The power failure feature refers to the signal that the temperature control device stops supplying power to the 4G communication module. The power failure feature is triggered when the supply current approaches zero. The method for generating the power failure feature is common knowledge to those skilled in the art.

[0034] Step 102: Retrieve standby permission in response to power failure feature.

[0035] The standby license refers to the user's permission for the use of the backup battery. When the temperature control device stops supplying power to the 4G communication module, it queries the user command in the 4G communication module's cache as the standby license. The user command refers to the MQTT instruction sent by the user through the cloud platform to the 4G communication module, which is converted into a flash instruction and recorded in the 4G communication module's cache. The flash instruction is used as the user command. The standby license is determined by the staff based on the actual situation.

[0036] Step 103: When the backup permission is consistent with the preset availability state, a backup power supply command is generated and sent based on the preset backup circuit.

[0037] The availability status refers to the permission to activate the backup battery. The availability status is pre-selected and entered by the staff based on the actual situation.

[0038] The fact that the backup permission is consistent with the preset available status means that the user allows the backup battery to be activated. The backup circuit refers to the current loop that supplies power to the 4G communication module from the backup battery. The backup circuit is selected by the staff according to the actual situation.

[0039] The backup power supply command refers to the command that controls the backup battery to supply power to the 4G communication module through the backup circuit. The method of generating the backup power supply command is common knowledge to those skilled in the art.

[0040] The 4G communication module monitors the power supply status of the temperature control device in real time. When it detects that the temperature control device has stopped supplying power to the 4G communication module, it calls the backup permission in the instruction record and compares the backup permission with the available status to determine whether the user allows the 4G communication module to use the backup battery. When the two are consistent, the backup battery is allowed to be used, reducing the situation where the 4G communication module uses the backup battery when the user does not allow it, and reducing the situation where the backup battery is exhausted during warehousing and transportation.

[0041] The cloud-based method for managing the battery of a 4G communication module in a temperature control device also includes: Step 104: When the backup license is consistent with the preset available state, collect the communication data sent by the communication module.

[0042] Communication data refers to the data stream transmitted from the 4G communication module received from the cloud platform, which is determined by the staff based on the actual situation.

[0043] Step 105: Determine the data content based on the communication data.

[0044] Data content refers to the actual meaning represented by communication data. Data content is the text content obtained by analyzing communication data, which is determined by staff based on the actual situation.

[0045] Step 106: If the data content is consistent with the preset default data, then determine the default duration in response to the data content.

[0046] Default data refers to the text data transmitted when the 4G communication module is not connected to the temperature control device. For example, the content is zero or empty. The default data is preset by the staff according to the actual situation. If the data content is the same as the default data, it means that the 4G communication module may be disconnected.

[0047] The default duration refers to the duration of the 4G communication module disconnection. The time is counted from when the data content is consistent with the default data.

[0048] Step 107: When the default duration exceeds the preset default threshold, generate and send a backup shutdown command based on the default duration.

[0049] The default threshold refers to the time threshold for determining when the 4G communication module disconnects. The default threshold is selected by the staff based on the actual situation. When the default duration exceeds the default threshold, the 4G communication module and the temperature control equipment will disconnect.

[0050] The backup shutdown command is a command to shut down the backup battery. It is triggered when the 4G communication module is in a special state, such as when the 4G communication module is disconnected from the temperature control device, when the 4G communication module data is distorted, or when the 4G communication module is under vibration. The method for generating this command is common knowledge to those skilled in the art.

[0051] With the backup battery enabled, the cloud platform collects communication data sent by the 4G communication module and compares the data text content with the default data when the 4G communication module is not connected to the temperature control device. When the two match, the default duration is recorded. If the default duration is too long, it is determined that the connection between the 4G communication module and the temperature control device is interrupted. At this time, the backup battery stops supplying power to the 4G communication module, reducing the unnecessary power consumption of the backup battery and reducing the possibility of the backup battery being completely depleted when the 4G communication module is disconnected from the device.

[0052] The cloud-based method for managing the battery of a 4G communication module in a temperature control device also includes: Step 108: When the default duration is not greater than the preset default threshold, analyze the data type based on the data content.

[0053] Data type refers to the category of data content. The cloud platform reads the category corresponding to the data content as the data type, such as ambient temperature, ambient humidity, target temperature, evaporator temperature, condenser temperature, etc., which are determined by the staff based on the actual situation.

[0054] Step 109: Analyze the association type based on the data type.

[0055] Association type refers to the data type that has a direct relationship with the data type. For example, ambient temperature corresponds to ambient humidity, and target temperature corresponds to evaporator temperature and condenser temperature. The association type corresponding to the data type can be found from the type correspondence table. The type correspondence table is a data table that records different data types and their corresponding association types.

[0056] Step 110: Select the calculated data according to the data type, and obtain the associated data based on the calculated data and the association type.

[0057] Calculated data refers to all the specific content contained in a data type. The communication data content of the past time period is stored in the 4G communication module, and a data record table is formed according to the timestamp and data type. Data with different timestamps of different data types are selected from the data record table as calculated data. The method of selecting calculated data is determined by the staff based on the actual situation.

[0058] Related data refers to all data of a related type. Data of the same type as the calculated data timestamp are selected from the data record table as related data. The method of selecting related data is determined by the staff based on the actual situation.

[0059] Step 111: Analyze and calculate the correlation data to obtain theoretical data.

[0060] Theoretical data refers to data transmitted under normal operating conditions. For example, an ambient temperature of 22.6℃ corresponds to an ambient humidity of 48.2%. The theoretical data corresponding to the associated data can be found in the theoretical correspondence table, which is a data table that records different associated data and their corresponding theoretical data.

[0061] Step 112: Compare the calculated data with the theoretical data to determine the deviation data.

[0062] Deviation data refers to the deviation value of the calculated data. The difference between the calculated data and the theoretical data is used as the deviation data.

[0063] Step 113: If the deviation data exceeds the preset allowable range, determine the distortion ratio based on the deviation data and data content.

[0064] The allowable range refers to the upper and lower limits of data deviation. When the deviation data is within the allowable range, it can be guaranteed that the transmitted data will not be distorted. The allowable range is preset by the staff according to the actual situation. Deviation data exceeding the allowable range means that the data is distorted.

[0065] The distortion ratio refers to the proportion of distorted data in the data content. Distorted data refers to calculated data whose deviation exceeds the allowable range. The distortion ratio is the quotient of the total number of statistically distorted data and the total number of calculated data. The method for determining the distortion ratio is selected by the staff based on the actual situation.

[0066] Step 114: When the distortion ratio is greater than the preset distortion threshold, generate and send a backup shutdown command based on the distortion ratio.

[0067] The distortion threshold refers to the critical value of the distortion ratio. When the distortion ratio is greater than the distortion threshold, the data transmitted by the 4G communication module will be severely distorted, which will cause the 4G communication module to fail to work properly.

[0068] When the default duration is not too long, the data text content is analyzed to determine the data category, and data that is directly related to the data category is selected as the associated data. Theoretical data is then calculated based on the associated data and compared with the actual calculated data. When the deviation between the two is too large, the distortion ratio is calculated based on the deviation data. When the distortion ratio is too large, the backup battery is stopped from supplying power to the 4G communication module, reducing the ineffective power consumption of the backup battery of the 4G communication module and reducing the possibility of the backup battery being completely consumed when the 4G communication module data is distorted.

[0069] The cloud-based method for managing the battery of a 4G communication module in a temperature control device also includes: Step 115: When the distortion ratio is greater than the preset distortion threshold, determine the actual signal strength based on the communication data.

[0070] Actual signal strength refers to the signal energy between the cloud platform and the 4G communication module, which is determined by the staff based on the actual situation.

[0071] Step 116: Determine the intensity difference curve based on the actual signal strength and the preset reference strength.

[0072] The baseline strength refers to the standard value of the 4G communication module signal strength when the temperature control equipment is not vibrating, which is preset by the staff according to the actual situation.

[0073] The intensity difference curve is a curve that shows the change in signal intensity. It is formed by continuously plotting the intensity difference between the actual signal intensity and the reference intensity over time.

[0074] Step 117: Determine the equipment vibration curve in response to the intensity difference curve.

[0075] The equipment vibration curve is a curve that shows the vibration of the equipment. The curve formed by continuously plotting the equipment amplitude according to the time series is used as the equipment vibration curve. The equipment amplitude corresponding to the intensity difference can be found from the amplitude correspondence table, which is a data table that records different intensity differences and their corresponding equipment amplitudes.

[0076] Step 118: Determine the maximum amplitude based on the equipment vibration curve.

[0077] Maximum amplitude refers to the maximum stroke of the equipment during vibration. The data of adjacent peaks and troughs in the vibration curve of the equipment can be read and the difference between them can be calculated as the candidate amplitude. All candidate amplitudes are counted and the maximum value is selected as the maximum amplitude.

[0078] Step 119: When the maximum amplitude is greater than the preset amplitude threshold, generate and send a backup shutdown command based on the maximum amplitude.

[0079] The amplitude threshold refers to the maximum vibration amplitude when the equipment is working safely. When the maximum amplitude exceeds the amplitude threshold, the 4G communication module is prone to instability. The amplitude threshold is preset by the staff according to the actual situation.

[0080] When the data distortion ratio is too high, the signal strength at each time point is obtained through the communication data between the 4G communication module and the cloud platform. Based on the corresponding relationship, the equipment vibration curve reflecting the equipment vibration is obtained. The maximum amplitude of the equipment is read from the equipment vibration curve. Thus, when the maximum amplitude is too high, it is judged that the operating state of the 4G communication module is not stable enough. Then, the power supply of the backup battery to the 4G communication module is stopped, reducing the ineffective power consumption of the backup battery of the 4G communication module and reducing the situation where the backup battery is completely consumed when the 4G communication module is in a vibration environment.

[0081] Reference Figure 2 Connection analysis methods include: Step 200: When the maximum amplitude is greater than the preset amplitude threshold, capture window data by combining communication data and the preset time window.

[0082] The time window refers to the length of time during which data is captured, and it is selected by staff based on the actual situation.

[0083] Window data refers to data within a time window. Communication data is extracted into multiple data segments according to the time window as window data. The method for selecting window data is determined by the staff based on the actual situation.

[0084] Step 201: Calculate the disconnection rate based on window data.

[0085] The disconnection ratio refers to the proportion of disconnection times in the total data within a time window. The number of disconnections refers to the number of times the data content is consistent with the preset default data. The ratio of the number of disconnections to the total number of data in the window is used as the disconnection ratio. The method for selecting the disconnection ratio is determined by the staff according to the actual situation.

[0086] Step 202: Determine the disconnection trend in response to the disconnection ratio, and retrieve the number of times the backup battery has been activated.

[0087] The trend of disconnection refers to the growth rate of the predicted disconnection ratio. The curve formed by continuously plotting the disconnection ratio in chronological order is called the disconnection curve. The predicted ratio at the next time node is predicted by the disconnection curve. The slope of disconnection is determined by the predicted ratio and the final disconnection ratio of the disconnection curve. The slope of disconnection is used as the disconnection trend. The method for determining the disconnection trend is selected by the staff according to the actual situation.

[0088] The number of times the backup power supply command is invoked refers to the number of times step 102 is executed. The method for determining the number of times the backup power supply command is invoked is selected by the staff according to the actual situation.

[0089] Step 203: Determine the probability of disconnection by combining the number of times the connection is activated and the disconnection trend.

[0090] The probability of detachment refers to the likelihood that the 4G communication module will fall off the temperature control device. The greater the number of activations and the greater the disconnection trend, the greater the probability of detachment. The probability of detachment corresponding to the number of activations and the disconnection trend can be found in the probability correspondence table. The probability correspondence table is a data table that records different activations and disconnection trends and their corresponding detachment probabilities.

[0091] Step 204: When the loosening probability is greater than the preset loosening threshold, generate and send a backup shutdown command based on the loosening probability.

[0092] The detachment threshold is the critical value for determining the detachment failure of a 4G communication module. When the probability of detachment exceeds the detachment threshold, the 4G module may detach from the temperature control device. The detachment threshold can be preset by the staff according to the actual situation.

[0093] When the maximum amplitude is too large, communication data is captured according to the time window and the number of signal disconnections within different time windows is analyzed. The disconnection ratio is obtained based on the number of signal disconnections and arranged in chronological order to predict the growth rate of the disconnection ratio. Combined with the number of times the backup battery is activated, the probability of the 4G communication module detaching from the temperature control device is determined. Thus, when the connection between the 4G communication module and the temperature control device is unreliable, the backup battery's power supply to the 4G communication module is stopped, reducing the ineffective power consumption of the 4G communication module's backup battery and reducing the situation where the backup battery is completely consumed when the 4G communication module is in a detached state.

[0094] Connection analysis methods also include: Step 205: When the probability of loosening is greater than the preset loosening threshold, determine the vibration direction based on the number of activations and the disconnection ratio.

[0095] Vibration orientation refers to the orientation of a single vibration of the 4G communication module. The activation time of the backup battery is determined based on the number of activations, and the disconnection time of the backup battery is determined based on the disconnection ratio. The activation and disconnection times are arranged in chronological order. The power pin and data transmission pin of the 4G communication module are located in different orientations. If there is an activation time at a given time point, the direction of the power pin is used as the vibration orientation. If there is a disconnection time point, the direction of the data transmission pin is used as the vibration orientation. If there are both activation and disconnection times at a given time point, the directions of both the power pin and the data transmission pin are used as the vibration orientation. The method for determining the vibration orientation is selected by the staff based on the actual situation.

[0096] Step 206: Determine the vibration timing based on the vibration orientation.

[0097] Vibration timing refers to the sequence of vibrations of a 4G communication module. It is the sequence of vibration locations recorded in chronological order. The method for determining the vibration timing is selected by the staff according to the actual situation.

[0098] Step 207: Analyze the vibration timing sequence to determine the vibration direction.

[0099] Vibration direction refers to the specific direction of the components that generate vibration on the temperature control equipment. The propagation direction of the vibration wave is determined by the vibration timing sequence, and the propagation direction of the vibration wave, the opposite direction of the vibration wave, and the direction perpendicular to the propagation of the vibration wave are taken as the vibration direction. The method of determining the vibration direction is selected by the staff according to the actual situation.

[0100] Step 208: Determine the vibration location based on the vibration direction.

[0101] Vibrating parts refer to the components of temperature control equipment that generate vibration. Components in the direction of vibration are selected as vibrating parts, and the method of selecting vibrating parts is determined by the staff according to the actual situation.

[0102] Step 209: Generate and display vibration warnings based on the vibration location.

[0103] Vibration warning refers to an alert that displays information about the vibrating part to the staff. The method of generating the vibration warning is selected by the staff based on the actual situation.

[0104] When the connection between the 4G communication module and the temperature control equipment is unreliable, the vibration location of the 4G communication module being disconnected is determined based on the number of times it is activated and the proportion of disconnections. The vibration locations are then arranged according to time to obtain the vibration sequence. Based on the vibration sequence, vibration propagation is simulated to infer the vibration direction, which in turn leads to the location of vibration on the temperature control equipment. This prompts staff to take timely action and improves the stability of the 4G communication module in vibration environments.

[0105] Connection analysis methods also include: Step 210: When the probability of detachment is greater than the preset detachment threshold, determine the predicted signal strength based on the number of times it is activated.

[0106] Predicted signal strength refers to the theoretical signal energy between the cloud platform and the 4G communication module. The more times the 4G communication module is activated, the more times it switches from direct power supply to backup battery power supply. The more unstable the working state, the lower the predicted signal strength. The predicted signal strength corresponding to the number of activations can be found in the signal correspondence table, which is a data table that records different activations and their corresponding predicted signal strengths.

[0107] Step 211: Compare the predicted signal strength with the actual signal strength to determine the strength deviation, and retrieve historical data.

[0108] Strength deviation refers to the difference between the predicted signal strength and the actual signal strength. The difference between the predicted signal strength and the actual signal strength can be used as the strength deviation. The method for determining the strength deviation is determined by the staff based on the actual situation.

[0109] Historical data refers to communication data stored in the past. After receiving the communication data, the cloud platform stores the data in the historical database, and all data in the historical database can be used as historical data.

[0110] Step 212: Identify disconnected nodes from historical data.

[0111] A disconnection node refers to the time point when the 4G communication module becomes loose and fails. The time point when historical data can be read and the generated data content is consistent with the default data is used as the disconnection node. The method for selecting disconnection nodes is determined by the staff based on the actual situation.

[0112] Step 213: Calculate the signal strength fluctuation before and after the disconnection node.

[0113] The fluctuation value refers to the magnitude of signal strength fluctuation. It is determined by retrieving the signal strength of the previous time point before the disconnection point and the corresponding signal strength of the disconnection point from historical data, and taking the difference between the two as the fluctuation value. The method for selecting the fluctuation value is determined by the staff based on the actual situation.

[0114] Step 214: Determine the drop height of the communication module in response to the fluctuation value.

[0115] The fall height refers to the vertical height difference between the starting position and the stopping position of the 4G communication module. The larger the fluctuation value, the greater the fall height. The fall height corresponding to the fluctuation value can be found in the height correspondence table, which is a data table that records different fluctuation values ​​and their corresponding fall heights.

[0116] Step 215: Determine the fall deviation of the communication module based on the fall height.

[0117] Fall deviation refers to the maximum fluctuation value of signal strength between the cloud platform and the 4G communication module. The greater the fall height, the greater the fall deviation. The fall deviation corresponding to the fall height can be found in the deviation correspondence table, which is a data table that records different fall heights and their corresponding fall deviations.

[0118] Step 216: When the strength deviation is not greater than the drop deviation, determine the specific damaged parts by combining the strength deviation and the drop height.

[0119] A strength deviation not greater than the drop deviation indicates that the signal strength deviation may be caused by the 4G communication module being dropped.

[0120] Damaged components refer to the specific parts of the 4G communication module that are damaged. The damaged components corresponding to the drop height and strength deviation can be found in the damage correspondence table. The damage correspondence table is a data table that records different drop heights and strength deviations and their corresponding damaged components.

[0121] Step 217: Generate and display component damage warnings based on damaged components.

[0122] Component damage warning refers to an alert that displays information about damaged components to staff. The method for generating component damage warnings is selected by staff based on the actual situation.

[0123] When the probability of detachment is too high, the theoretical signal strength is calculated based on the number of times the backup battery has been activated. The difference between the theoretical signal strength and the actual signal strength is calculated as the strength deviation. At the same time, historical communication data before and after the 4G communication module is dropped is retrieved and analyzed to determine the drop height of the 4G communication module, thereby predicting the maximum drop deviation of the 4G communication module at the drop height. If the strength deviation is less than the drop deviation, it means that the signal fluctuation is caused by damage to the 4G communication module. At this time, the drop height and strength deviation are analyzed to determine the actual damaged component, and the staff is reminded to deal with it in time to improve the reliability of the 4G communication module operation.

[0124] Connection analysis methods also include: Step 218: When the strength deviation is less than the drop deviation, determine the degree of damage based on the drop height.

[0125] The degree of damage refers to the extent of damage to the damaged parts. The higher the fall height, the greater the degree of damage to the parts. The degree of damage corresponding to the fall height can be found in the damage correspondence table, which is a data table that records different fall heights and their corresponding degrees of damage.

[0126] Step 219: Determine component deviations based on the degree of damage.

[0127] Partial deviation refers to the signal strength deviation caused by damaged components. The same component will have different partial deviations under different degrees of damage. The greater the degree of damage, the greater the partial deviation. The corresponding partial deviation of the component can be found in the partial correspondence table. The partial correspondence table is a data table that records different degrees of damage, components and their corresponding partial deviations.

[0128] Step 220: Determine the deviation value by combining the component deviation and the strength deviation.

[0129] The deviation value refers to the error value of signal deviation and intensity deviation caused by damage to a part. The difference between the component deviation and the intensity deviation can be used as the deviation value. The method of determining the deviation value is selected by the staff according to the actual situation.

[0130] Step 221: If the deviation value exceeds the preset deviation threshold, generate an impact force distribution map based on the component deviation and strength deviation.

[0131] The deviation threshold refers to the maximum deviation value caused by the damage of a single component. The deviation threshold is pre-entered by the staff based on the actual situation. If the deviation value exceeds the deviation threshold, it means that multiple components may be damaged.

[0132] An impact force distribution map is an image that shows the distribution of impact force on a damaged component. The method for generating an impact force distribution map is detailed below.

[0133] Step 222: Determine the number of impacts based on the impact force distribution map.

[0134] The number of impact points refers to the number of impact points. The number of peak impact forces is selected as the number of impact points. The method for generating the number of impact points is selected by the staff based on the actual situation.

[0135] Step 223: When the number of impacts is not greater than the preset impact threshold, generate and display a component damage warning based on the impact force distribution map.

[0136] The impact threshold refers to the maximum number of impacts. The number of impacts generated when a 4G communication module falls from the same height is limited. When the number of impacts exceeds the impact threshold, it means that the impact threshold will not occur in actual circumstances, and therefore the damaged parts corresponding to the number of impacts will not be displayed. The impact threshold is pre-entered by the staff according to the actual situation.

[0137] When the probability of loosening is too high, the impact force distribution map under different possible component damage is simulated based on component deviation and strength deviation. Thus, when the number of impact points in the impact force distribution map is too large, it is determined that the situation does not conform to reality, thereby filtering out the corresponding possible component damage and improving the accuracy of damage identification.

[0138] Reference Figure 3The methods for generating impact force distribution maps include: Step 300: Determine the weight of each component based on the component deviation and strength deviation, and obtain the combination of damaged weights.

[0139] Damage weight combination refers to the possible damage situations of components that meet the strength deviation, that is, the set of different components and their corresponding damage degrees. Component weight refers to the damage degree of each component, and weight deviation refers to the strength deviation of each component. The deviation of each component can be obtained by calculating the product of the component weight and weight deviation of different components. The deviations of each component are combined and added together to make the result consistent with the strength deviation. The combination method is used as the damage weight combination. The component weight corresponding to the fall height can be found from the weight correspondence table, and the weight deviation corresponding to the damage degree can be found from the weight deviation correspondence table. The weight correspondence table is a data table that records different fall heights and their corresponding component weights. The weight deviation correspondence table is a data table that records different damage degrees and their corresponding weight deviations. The selection method of damage weight combination is determined by the staff according to the actual situation.

[0140] Step 301: Extract the weight degree from the damaged weight combination.

[0141] The degree of weight refers to the degree of damage to each component in the combination of damaged weights, i.e., the component weights mentioned above.

[0142] Step 302: Determine the impact intensity based on the weighting degree, and extract the weight position from the damaged weight combination.

[0143] Impact intensity refers to the magnitude of the impact force. The greater the weight, the greater the impact intensity. First, extract the weighted components from the damaged weighted combination, and then look up the impact intensity corresponding to the weight and weighted components in the intensity correspondence table. The intensity correspondence table is a data table that records different weight levels and their corresponding impact intensities.

[0144] The weighted position refers to the location of the weighted component, which is the component location of the 4G communication module. The selection method of the weighted position is determined by the staff based on the actual situation.

[0145] Step 303: Generate an impact force distribution map by combining the impact intensity and weighted location.

[0146] An impact force distribution map is an image that shows the distribution of impact force on a damaged component. The impact force is distributed according to the weighted position and the resulting image is used as the impact force distribution map. The method of generating the impact force distribution map is determined by the staff.

[0147] By weighting and combining the deviations of each component, the damage weight combination corresponding to different possible component damage is obtained. The impact force received by the component during the fall is matched according to the weight degree of damage of different components, and the impact force is matched with the weight position of the corresponding component to form an impact force distribution map, thereby improving the accuracy of damage identification.
