[0036] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] The embodiment of the present invention provides a method for monitoring the separation of a person and a vehicle during charging of a mobile charging vehicle. Figure 1 As shown, including:

[0038] Step 1: Conduct risk assessment on charging events of mobile charging vehicles;

[0039] The charging task received by the mobile charging vehicle from the charging scheduling platform is regarded as a charging event; the charging task is that the user of the electric vehicle that needs to be charged sends a charging application to the charging scheduling platform through a mobile terminal. When the charging scheduling platform receives the charging application, it generates a charging task based on the location of the electric vehicle or the location specified by the customer, the charging demand and other parameters; the charging scheduling platform publishes the charging task, and the driver of the mobile charging vehicle accepts the published charging task; the accepted charging task is converted into the charging event currently being performed by the mobile charging vehicle; the elements of the charging event include: event location, charging demand, brand, model, license plate, etc. of the car to be charged;

[0040] Among them, the risk assessment steps include: determining the first risk level of the risk level area where the event location of the charging event is located from a pre-configured risk area map; obtaining the perimeter environment of the event location, analyzing the perimeter environment, and determining the second risk level; comprehensively analyzing the first risk level and the second risk level to determine the risk assessment result. For example: the risk level area is divided into one, two, and three, corresponding to low risk, medium risk, and high risk respectively; the risk area map is to configure different risk level areas in the map, for example: the urban area is divided into level one, the suburbs are divided into level two, and the countryside is divided into level three; when the event location is located in the urban area, the first risk level is one; for another example: the risk level of the perimeter environment is divided into A, B, and C; corresponding to low risk, medium risk, and high risk respectively, the analysis steps of the perimeter environment are: feature extraction of the perimeter environment data, constructing an analysis parameter set based on the extracted feature parameters, and then retrieving the corresponding associated risk level from the pre-configured risk analysis library based on the analysis parameter set; when the second risk level after analysis is A, the final risk assessment result is A. The perimeter environment data include: whether it is located in an underground parking lot, the number of vehicles entering and exiting the parking lot when it is located in the parking lot, whether it is located on the side of a main road, the traffic conditions on the main road when it is located on the side of a main road, the shortest distance from a safe house (an agency or unit that can be used as an emergency shelter), etc.; the parameters in the analysis parameter set include: a parameter indicating whether it is located in an underground parking lot, a parameter indicating the number of vehicles entering and exiting the parking lot when it is located in the parking lot, a parameter indicating whether it is located on the side of a main road, a parameter indicating the traffic conditions on the main road when it is located on the side of a main road, a parameter indicating the shortest distance from a safe house (an agency or unit that can be used as an emergency shelter), etc.; the risk analysis library is pre-configured, and the analysis parameter set is associated with the risk level one by one in the library;

[0041] Step 2: Configure alarm conditions based on risk assessment results;

[0042] The alarm conditions include: a distance threshold for the separation between the driver and the mobile charging vehicle during the charging process of the mobile charging vehicle, a first time threshold for the charging connection of the mobile charging vehicle at the working position, and a second time threshold for the recovery of the charging connection equipment at the end of charging. The specific configuration method can use a pre-configured alarm condition parameter query table to query according to the risk assessment result to obtain the specific parameter values ​​of each alarm condition; for example: when the risk assessment result is A, the alarm condition is configured as the distance threshold for the separation between the driver and the mobile charging vehicle during the charging process of the mobile charging vehicle is 50 meters; when the risk assessment result is C, the alarm condition is configured as the distance threshold for the separation between the driver and the mobile charging vehicle during the charging process of the mobile charging vehicle is 2 meters, the first time threshold for the charging connection of the mobile charging vehicle at the working position is 2 minutes, and the second time threshold for the recovery of the charging connection equipment at the end of charging is 2 minutes. Generally speaking, the higher the risk of the risk assessment result, the more conditions need to be configured, and the higher the requirements of each condition.

[0043] Step 3: Using alarm conditions to make alarm determination on the monitoring data of the separation of people and vehicles;

[0044] The implementation method of the vehicle-person separation monitoring includes: through a first monitoring module set in the cab of the mobile charging vehicle; and / or, a second monitoring module worn by the driver, and / or, a third monitoring module for status detection of the charging device. Among them, the first monitoring module includes an image acquisition unit set in the cab and / or a pressure monitoring unit set on the driver's seat. Among them, the second monitoring module includes: a positioning module; wherein the positioning module includes: a GPS positioning module, a Beidou positioning module, an RFID positioning module, a Bluetooth positioning module, or one or more combinations thereof. The first monitoring module can monitor whether the driver is in the cab, and the second monitoring module can monitor the driver's position; the data of the first monitoring module and the second monitoring module are analyzed to obtain the monitoring data of the separation of man and vehicle monitoring, including: when the distance between the position represented by the positioning information of the mobile charging vehicle and the event position is less than the preset distance (any value between 1 meter and 10 meters), the first monitoring module monitors the driver leaving the cab as the starting timing time of arriving at the working position; the time when the third monitoring module detects that the charging equipment starts to run is used as the connection completion time for completing the charging connection; the time when the third monitoring module detects that the charging gun is pulled out of the car to be charged is used as the charging completion time; the time when the driver returns to the cab after the first monitoring module monitors the charging completion time is used as the recovery completion time; the distance between the position monitored by the second monitoring module during the period when the driver leaves the cab and the position monitored by the positioning module of the mobile charging vehicle is recorded. The alarm determination step is: in the process of recording the distance between the position monitored by the second monitoring module during the period when the driver leaves the cab and the position monitored by the positioning module of the mobile charging vehicle, the newly recorded distance value is compared with the distance threshold, and when it is greater than or equal to the distance threshold, an alarm is output; after the connection completion time is recorded, the difference between the connection completion time and the start timing time is compared with the first time threshold, and when it is greater than or equal to the first time threshold, an alarm is output; the difference between the recovery completion time and the charging completion time is compared with the second time threshold, and when it is greater than or equal to, an alarm is output. Among them, the third monitoring module includes: a contact sensor set on the charging gun, a voltage and current detection unit at the charging output end, a data acquisition unit connected to the controller of the charging device, a processor and a communication module; the processor is electrically connected to the communication module, the contact sensor, the voltage and current detection unit, and the data acquisition unit respectively.

[0045] In one embodiment, the monitoring of human-vehicle separation can also be applied to the scheduling scenario of the charging scheduling platform. When the driver of the mobile charging vehicle selects the scheduling mode as system dispatch, the distance between the driver and the mobile vehicle in the monitoring data is compared with the pre-configured threshold distance for canceling the authority of the person corresponding to the system dispatch (any value between 10 meters and 50 meters). When it is greater than or equal to the threshold distance, the authority of the person corresponding to the system dispatch is canceled; the system dispatch mode is exited through human-vehicle separation monitoring to deal with the situation where the charging scheduling platform still places orders after dispatching when the driver subjectively does not accept the order but forgets to change his own scheduling mode; since it takes a certain amount of time for the driver to leave the mobile charging vehicle, the system may have already dispatched during this period. Therefore, while canceling the authority of the person corresponding to the system dispatch, it is determined whether there is a new charging task. If so, the charging task will be reassigned to other mobile charging vehicles. There is another situation in the above method. When the driver takes down the second monitoring module and places it in the cab, effective identification cannot be performed. However, the last image of the driver in the cab taken by the first monitoring module can be analyzed to determine whether the driver is wearing the second monitoring module. If the driver is not wearing the second monitoring module, the authority of the person corresponding to the system dispatch is immediately revoked.

[0046] When the driver of the mobile charging vehicle selects the dispatch mode as the grab order mode, that is, manually accepting the published charging tasks; it is necessary to monitor the separation of people and vehicles, and the grab order operation is allowed only when the driver is in the cab.

[0047] Since the charging process is sometimes long, the driver can use the time to handle permitted daily matters (for example, going to eat, going to the bathroom, etc.). At this time, the driver needs to press the corresponding button of the second monitoring module or use a mobile terminal to send an application to the platform to verify the application event. When the verification is passed, different alarm shielding times are configured according to the application event and the application time, and only the human-vehicle separation data is monitored. The verification of the application event includes: when the event is to go to eat, verify whether the application event is within the pre-configured meal time threshold interval (6 to 8 am, 11 to 2 pm, 5 to 7 pm). If so, the verification is passed; the alarm shielding time is associated with the application event one by one.

[0048] In one embodiment, since the mobile charging vehicle does not require the driver to operate the electric vehicle to be charged, in order to regulate the driver's behavior and avoid unnecessary trouble, the data of the vehicle separation monitoring also includes: the time the driver stays in the electric vehicle area to be charged; the steps for obtaining the stay time are as follows: when the charging gun is connected to the electric vehicle to be charged, according to the posture of the charging gun and the cable connected to it and the positioning information of the mobile charging vehicle, an analysis space is constructed; the analysis space includes the model of the mobile charging vehicle and the model of the electric vehicle to be charged, and the positional relationship of the two models is associated by the posture of the charging gun and the cable connected to it; the positioning information of the second monitoring module after the driver leaves the cab is obtained and the driver's model is mapped to the analysis space, and a dynamic analysis is performed to determine the total time of the overlap between the driver's model and the electric vehicle model; the total time is used as the time the driver stays in the electric vehicle area to be charged. The corresponding alarm conditions that can be configured synchronously also include: a stay time threshold, and an alarm is triggered when the stay time is greater than or equal to the stay time threshold.

[0049] The present invention also provides a monitoring system for the separation of a person and a vehicle during the charging process of a mobile charging vehicle, such as Figure 2 As shown, it includes: a risk assessment module 1, a configuration module 2 and an analysis module 3; wherein the risk assessment module 1 performs risk assessment on the charging events of the mobile charging vehicle; the configuration module 2 configures the alarm conditions according to the risk assessment results; the analysis module 3 uses the alarm conditions to perform alarm judgment on the monitoring data of the human-vehicle separation monitoring; wherein the implementation method of the human-vehicle separation monitoring includes: through a first monitoring module set in the cab of the mobile charging vehicle; and / or, a second monitoring module worn by the driver, and / or, a third monitoring module for status detection of the charging equipment.

[0050] The steps of risk assessment include:

[0051] Determine, from a preconfigured risk area map, a first risk level of a risk level area where an event location of the charging event is located;

[0052] Obtain the perimeter environment of the event location, analyze the perimeter environment, and determine the second risk level;

[0053] Comprehensively analyze the first risk level and the second risk level to determine the risk assessment results.

[0054] Among them, the alarm conditions include:

[0055] One or more of a distance threshold for separation between the driver and the mobile charging vehicle during charging of the mobile charging vehicle, a first time threshold for charging connection of the mobile charging vehicle when arriving at the working position, and a second time threshold for recovery of the charging connection device at the end of charging are combined.

[0057] Among them, the second monitoring module includes: a positioning module; wherein the positioning module includes: a GPS positioning module, a Beidou positioning module, an RFID positioning module, a Bluetooth positioning module or one or more combinations thereof.
