[0051] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0052] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0053] The main solution of the embodiment of the present application is: in response to a charging request of an automatic guided vehicle, a charging start instruction is generated according to the target charging duration of the automatic guided vehicle; the charging start instruction is sent to a time control integrated device, so that the time control integrated device charges according to the charging start instruction and feeds back the charging current during the charging process; a safety analysis of the charging workshop is performed based on the charging current, charging duration and workshop temperature data fed back by a temperature sensing device to obtain a safety analysis result; and workshop monitoring of the charging workshop where the automatic guided vehicle is located is performed based on the safety analysis result.

[0054] The current AGV charging area temperature monitoring system still has shortcomings and cannot achieve real-time intelligent monitoring and management.

[0055] The present application provides a solution that realizes intelligent and all-round monitoring and management of the charging workshop where the automated guided vehicle is located, effectively improving the environmental safety of the charging workshop and reducing the risk of dangerous accidents.

[0056] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a workshop monitoring device based on digital twins that can realize the above functions. The following takes the workshop monitoring device based on digital twins as an example of the execution subject to illustrate this embodiment and the following embodiments.

[0057] Based on this, the embodiment of the present application provides a workshop monitoring method based on digital twins, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the workshop monitoring method based on digital twins of the present application.

[0058] In this embodiment, the workshop monitoring method based on digital twin is applied to the digital twin system, and the method includes steps S10 to S40:

[0059] Step S10, in response to a charging request of the automated guided vehicle, generating a charging start instruction according to a target charging duration of the automated guided vehicle.

[0060] It should be noted that a digital twin system is built in the workshop monitoring device based on digital twin in this embodiment. The digital twin system builds a digital twin model corresponding to the charging workshop based on the acquired image information and collected data of the charging workshop. The digital twin model can display various operating data of the charging workshop and the charging status of the AGV in real time. In this embodiment, the charging workshop is the charging workshop where the AGV is located, and the workshop contains the charging area of ​​the AGV. The digital twin model corresponding to the charging workshop is the virtual workshop model.

[0061] It is understandable that after being powered, the AGV will automatically drive into the charging area of ​​the charging workshop, dock with the charging equipment in the charging area, and then send a charging request to the digital twin system. At this time, the digital twin request will generate a charging start instruction based on the target charging duration. In this embodiment, the target charging duration refers to the duration of this charging set for the AGV; the target charging duration can be determined based on the remaining power of the AGV, or the user can set the target charging duration for each time. This embodiment does not limit the method for determining the target charging duration.

[0062] In a feasible implementation, step S10 may include steps A11 to A13:

[0063] Step A11, in response to a charging request of the automatic guided vehicle, obtaining the remaining power of the automatic guided vehicle.

[0064] Step A12, determining a target charging time according to the remaining power and the charging power.

[0065] Step A13: generating a charging start instruction according to the target charging duration.

[0066] It should be noted that upon receiving a charging request from the AGV, the digital twin system will obtain the remaining power of the AGV, calculate the difference between the remaining power and the target power, and calculate the duration by using the charging power and power difference provided by the charging area of ​​the charging workshop, and determine the target charging duration, thereby generating a charging start instruction containing the target charging duration. In this embodiment, the target power can be set to the rated power of the AGV battery, or to a certain intermediate value, which is not limited in this embodiment.

[0067] Step S20, sending the charging start instruction to the time control integrated device, so that the time control integrated device charges according to the charging start instruction and feeds back the charging current during the charging process.

[0068] It should be noted that the time control integrated device refers to a time control switch device with a microprocessor in the charging area of ​​the charging workshop. The time control integrated device is connected to the charging equipment in the charging area and can monitor the charging current generated during the charging process in real time.

[0069] It is understandable that the digital twin system sends the charging start instruction to the time control integrated device, which turns on the power to charge the AGV and controls the power to disconnect according to the target charging time included in the charging start instruction. During the charging process, the time control integrated device monitors the charging current in real time and feeds back the charging current to the digital twin system.

[0070] Step S30, performing a safety analysis of the charging workshop according to the charging current, the charging duration, and the workshop temperature data fed back by the temperature sensing device to obtain a safety analysis result.

[0071] It should be noted that the temperature sensing device in this embodiment refers to a temperature sensing camera with a built-in thermal imager. The temperature sensing device is located in the charging workshop and can obtain the charging area temperature of the charging area in the charging workshop and the workshop ambient temperature corresponding to the environment outside the charging area in the charging workshop. Figure 2 As shown, 29.6°C is the charging area temperature, and 15.2°C is the workshop ambient temperature. In this embodiment, the workshop temperature data includes the charging area temperature and the workshop ambient temperature. After charging starts, the temperature sensing device will monitor the workshop temperature data in real time and transmit the workshop temperature data to the digital twin system.

[0072] It is understandable that the digital twin system analyzes the charging current, charging duration and workshop temperature data to determine whether there is a charging timeout, excessive current, or abnormal temperature, and obtains the corresponding safety analysis results based on the current situation. In this embodiment, the safety analysis results include normal charging results, workshop power-off results, and workshop warning results. When no abnormal situation occurs, the safety analysis result is a normal charging result, and charging is maintained at this time; when any abnormal situation occurs, such as charging timeout, excessive current, and the temperature of the charging area exceeds the set safety threshold, the safety analysis result is a workshop power-off result, and the digital twin system sends a signal to the time control integrated device to cut off the power supply and forcefully terminate the charging process; when any abnormal situation occurs, such as the temperature of the charging area exceeds the set warning temperature threshold, the ambient temperature of the workshop exceeds the set ambient temperature threshold, the fluctuation range of the temperature of the charging area is too large, and the fluctuation range of the ambient temperature of the workshop is too large, the safety analysis result is a workshop warning result, and charging is maintained at this time, but the digital twin system will generate an alarm message and push it.

[0073] Step S40: Perform workshop monitoring on the charging workshop where the automatic guided vehicle is located according to the safety analysis result.

[0074] It should be noted that the workshop monitoring of the charging workshop where the AGV is located is realized through the safety analysis results. The various data involved in the charging workshop will be displayed in real time at the corresponding position of the virtual workshop model through the display interface, and the data will be updated in real time. At the same time, after the charging is completed, the AGV enters the line body work, and the digital twin system will generate and save the charging report based on the various data collected during this charging process. The digital twin system will store the historical temperature data, charging records and various data of the charging workshop where the AGV is located, and generate an analysis report according to the preset time interval. In this embodiment, the preset time interval can be set to one month, or it can be set to other times according to needs, and this embodiment does not limit this.

[0075] In a feasible implementation, step S40 may include steps B11 to B13:

[0076] Step B11, when the safety analysis result is a workshop power outage result, generate a charging end instruction and an alarm message.

[0077] Step B12, sending the charging end instruction to the time control integrated device, so that the time control integrated device ends charging according to the charging end instruction.

[0078] Step B13, sending the alarm information to the user's terminal to issue a workshop safety alarm.

[0079] It should be noted that when the safety analysis result is a power outage in the workshop, it indicates that one or more abnormal conditions have occurred, including charging timeout, excessive current, and the temperature in the charging area exceeding the set safety threshold. At this time, the digital twin system generates a charging end instruction and generates an alarm message based on the abnormal condition that has occurred.

[0080] It is understandable that the digital twin system will send a charging end instruction to the time control integrated device, and the time control integrated device will cut off the power supply according to the charging end instruction and force the charging process to terminate; the digital twin system will send an alarm message to the user's terminal or central control room to issue a workshop safety alarm.

[0081] In a feasible implementation manner, after step S40, steps C11 to C13 may be included:

[0082] Step C11, integrating data on the virtual workshop model corresponding to the charging workshop according to the charging current, charging duration and workshop temperature data fed back by the temperature sensing device to obtain a target workshop model.

[0083] It should be noted that data integration is performed on the virtual workshop model corresponding to the charging workshop, and the collected data during the charging process, such as charging current, charging duration, and workshop temperature data, are integrated into the virtual workshop model, thereby obtaining a target workshop model containing various data.

[0084] Step C12: anomaly marking the integrated data in the target workshop model according to the safety analysis result to obtain a monitoring workshop model.

[0085] It should be noted that when the safety analysis result is a normal charging result, the data in the target workshop model will be displayed in a specific color such as green; when the safety analysis result is not a normal charging result, the data corresponding to the situation will be displayed in other colors such as red according to the abnormal situation that occurs, thereby obtaining a monitoring workshop model with the analysis results marked, and pushing the monitoring workshop model to the display interface for display, so that the user can intuitively and clearly understand the charging status of the AGV.

[0086] Step C13: Push the monitoring workshop model to the display interface for status display.

[0087] The method of this embodiment is applied to a digital twin system, and the method includes: in response to a charging request of an automated guided vehicle, generating a charging start instruction according to the target charging duration of the automated guided vehicle; sending the charging start instruction to a time control integrated device, so that the time control integrated device charges according to the charging start instruction and feeds back the charging current during the charging process; performing a safety analysis of the charging workshop according to the charging current, charging duration, and workshop temperature data fed back by a temperature sensing device to obtain a safety analysis result; and monitoring the charging workshop where the automated guided vehicle is located according to the safety analysis result. Through the above method, intelligent and all-round monitoring and management of the charging workshop where the automated guided vehicle is located is realized, which effectively improves the environmental safety of the charging workshop and reduces the risk of dangerous accidents.

[0088] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S30 in the workshop monitoring method based on digital twins also includes steps S31 to S33:

[0089] Step S31, comparing the charging current with a current threshold to obtain a first comparison result.

[0090] It should be noted that the charging current is compared with the set current threshold. When the charging current is less than or equal to the current threshold, the first comparison result is a normal current result; when the charging current is greater than the current threshold, the first comparison result is an overcharge power-off result. In this embodiment, the current threshold is set according to the specifications and safety standards of the AGV battery.

[0091] Step S32: compare the charging duration with the target charging duration to obtain a second comparison result.

[0092] It should be noted that the charging duration is compared with the target charging duration. When the charging duration is less than or equal to the target charging duration, the second comparison result is a normal duration result; when the charging duration is greater than the target charging duration, the second comparison result is an overcharge power-off result.

[0093] Step S33: determining a third comparison result according to the workshop temperature data fed back by the temperature sensing device and the target temperature threshold.

[0094] It should be noted that the target temperature threshold includes the regional temperature threshold and the ambient temperature threshold. The regional temperature threshold includes the safety threshold and the warning temperature threshold. The regional temperature threshold refers to the temperature threshold corresponding to the charging area of ​​the charging workshop. The ambient temperature threshold refers to the temperature threshold corresponding to the environment outside the charging area in the charging workshop. The safety threshold is greater than the warning temperature threshold.

[0095] In a feasible implementation, step S33 may include steps D11 to D14:

[0096] Step D11, determining the charging area temperature corresponding to the vehicle charging area in the charging workshop and the workshop ambient temperature of the charging workshop according to the workshop temperature data fed back by the temperature sensing device.

[0097] Step D12: Compare the charging area temperature with the area temperature threshold in the target temperature threshold to obtain a fourth comparison result.

[0098] It should be noted that the charging area temperature and the regional temperature threshold are compared. When the charging area temperature is less than or equal to the warning temperature threshold, the fourth comparison result is a normal temperature result; when the charging area temperature is greater than the warning temperature threshold and less than or equal to the safety threshold, the fourth comparison result is an overtemperature warning result; when the charging area temperature is greater than the safety threshold, the fourth comparison result is a high temperature power-off result.

[0099] Step D13: Compare the workshop ambient temperature with the ambient temperature threshold in the target temperature threshold to obtain a fifth comparison result.

[0100] It should be noted that the workshop ambient temperature is compared with the ambient temperature threshold. When the workshop ambient temperature is less than or equal to the ambient temperature threshold, the fifth comparison result is a normal temperature result; when the workshop ambient temperature is greater than the ambient temperature threshold, the fifth comparison result is an overtemperature warning result.

[0101] Step D14, when the fourth comparison result is a high temperature power-off result and the fifth comparison result is an over-temperature warning result, determining that the third comparison result is a high temperature power-off result.

[0102] It should be noted that when the fourth comparison result is a high temperature power off result and the fifth comparison result is an over-temperature warning result, the third comparison result is a high temperature power off result; when the fourth comparison result is not a high temperature power off result, and there is an over-temperature warning result in the fourth comparison result and the fifth comparison result, the third comparison result is an over-temperature warning result; when the fourth comparison result and the fifth comparison result are both normal temperature results, the third comparison result is a normal temperature result.

[0103] Step S34: determining a safety analysis result according to the first comparison result, the second comparison result and the third comparison result.

[0104] It should be noted that, when the first comparison result, the second comparison result and the third comparison result are all normal results, the safety analysis result is the safety analysis result; when there is a power off result in the first comparison result, the second comparison result and the third comparison result, the safety analysis result is a workshop power off result; when there is no power off result in the first comparison result, the second comparison result and the third comparison result, but there is a warning result in the first comparison result, the second comparison result and the third comparison result, the safety analysis result is a workshop warning result.

[0105] In a feasible implementation, step S34 may include steps E11 to E12:

[0106] Step E11: when a preset power-off result exists in the first comparison result, the second comparison result, and the third comparison result, determining that the safety analysis result is a workshop power-off result.

[0107] It should be noted that when there is a power-off result in the first comparison result, the second comparison result, and the third comparison result, it means that there is a preset power-off result, and the safety analysis result is a workshop power-off result. For example, if the first comparison result is an overcharge power-off result, the second comparison result is a normal time result, and the third comparison result is a normal temperature result, it means that there is a preset power-off result.

[0108] Step E12, when there is no preset power-off result in the first comparison result, the second comparison result and the third comparison result and there is a preset warning result in the first comparison result, the second comparison result and the third comparison result, determine that the safety analysis result is a workshop warning result.

[0109] It should be noted that when there is a power-off result but a preset warning result in the first comparison result, the second comparison result, and the third comparison result, the safety analysis result is determined to be a workshop warning result. For example, if the first comparison result is a normal current result, the second comparison result is a normal duration result, and the third comparison result is an overtemperature warning result, it means that there is a preset warning result.

[0110] This embodiment obtains a first comparison result by comparing the charging current with the current threshold; obtains a second comparison result by comparing the charging duration with the target charging duration; determines a third comparison result based on the workshop temperature data fed back by the temperature sensing device and the target temperature threshold; and determines a safety analysis result based on the first comparison result, the second comparison result, and the third comparison result. In the above manner, an accurate safety analysis result can be obtained.

[0111] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the workshop monitoring method based on digital twins of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
