[0068] AsFigure 2 As shown in the figure, Figure 2 As shown in the figure, the vehicle loading volume detection method includes steps 201-204:

[0069] 201, obtaining vehicle battery power, vehicle position, vehicle motion speed and / or door opening / closing detection data.

[0070] The vehicle loading volume detection method in this embodiment is applied to a vehicle loading volume detection device, and the type of the vehicle loading volume detection device is not specifically limited.

[0071] As shown in the figure, Figure 3 As shown in the figure, Figure 3 As shown in the figure, the vehicle loading volume detection method in this embodiment is a structural diagram of the vehicle loading volume detection device. The vehicle loading volume detection device in this embodiment includes a master control chip, a positioning module, a battery management module, a door opening / closing detection module and a volume detection module; the master control chip and the positioning module, the battery management module, the door opening / closing detection module and the volume detection module are in communication connection, the master control chip is used for information reading, processing and information storage from each module; the positioning module (also called 4G+GPS module) is used for reading GPS information (position and motion speed) and uploading data; the battery management module is used for power supply of the device when the trailer head and the trailer compartment are separated; the door opening / closing detection module is used for detecting the opening / closing state of the vehicle door; the volume detection module is used for measuring the volume of goods in the trailer compartment, and the volume detection module controls the laser radar, the cloud platform and other optical and mechanical devices to detect the vehicle loading volume.

[0072] The vehicle loading volume detection device receives a vehicle loading volume detection request, wherein the triggering mode of the vehicle loading volume detection request is not specifically limited, i.e., the vehicle loading volume detection request can be triggered by the user, for example, the user inputs a detection instruction on the vehicle loading volume detection device to actively trigger the vehicle loading volume detection request; in addition, the vehicle loading volume detection request can also be automatically triggered by the vehicle loading volume detection device, for example, the automatic triggering condition of the vehicle loading volume detection request in the vehicle loading volume detection device is vehicle starting, and the vehicle loading volume detection device detects vehicle starting to automatically trigger the vehicle loading volume detection request.

[0073] After the vehicle loading volume detection device receives the vehicle loading volume detection request, the vehicle loading volume detection device obtains the volume related to the vehicle state, i.e., the vehicle loading volume detection device obtains the vehicle battery power, the vehicle position, the vehicle motion speed and / or the door opening / closing detection data, wherein the vehicle battery power can be the battery power provided for the working of the vehicle loading volume detection device.

[0074] It can be understood that in the embodiment, after the vehicle loading volume amount detection device receives the vehicle loading volume amount detection request, initially acquires the vehicle-mounted battery power, the vehicle position, the vehicle movement speed and / or the door opening and closing detection data, the vehicle loading volume amount detection device sets the acquisition frequency of the vehicle-mounted battery power, the vehicle position, the vehicle movement speed and / or the door opening and closing detection data according to specific circumstances, so as to reduce the data acquisition amount of the vehicle loading volume amount detection device, and further reduce the data processing amount of the vehicle loading volume amount detection device.

[0075] 202, determining a vehicle state according to at least one of the vehicle position, the vehicle movement speed and / or the door opening and closing detection data.

[0076] The vehicle loading volume amount detection device determines the vehicle state according to at least one of the vehicle position, the vehicle movement speed and / or the door opening and closing detection data, wherein the vehicle state includes a working state and a non-working state.

[0077] The manner of determining the vehicle state in the embodiment is not limited, and a specific implementation manner of determining the vehicle state according to the vehicle position, the vehicle movement speed and the door opening and closing detection data by the vehicle loading volume amount detection device is given in the embodiment, including: the vehicle loading volume amount detection device judges whether the vehicle position changes, the vehicle loading volume amount detection device compares the vehicle movement speed with a preset speed threshold, wherein the preset speed threshold refers to the maximum speed in the working state of the vehicle, the vehicle loading volume amount detection device acquires the door opening and closing detection data, and determines the vehicle state, for example:

[0078] (1) if the vehicle position changes, the vehicle movement speed does not exceed the preset speed threshold, and the door opening and closing detection data is in the door opening state, it is determined that the vehicle state is in the working state;

[0079] (2) if the vehicle position does not change, the vehicle movement speed exceeds the preset speed threshold, or the door opening and closing detection data is in the door closing state, it is determined that the vehicle state is in the non-working state;

[0080] The vehicle loading volume amount detection device in the embodiment determines the vehicle state according to all data of the vehicle position, the vehicle movement speed and / or the door opening and closing detection data, so as to set the detection frequency of the vehicle loading volume according to the vehicle state, specifically:

[0081] 203, setting the detection frequency of the vehicle loading volume according to the vehicle-mounted battery power and the vehicle state.

[0082] The vehicle loading volume amount detection device sets the detection frequency of the vehicle loading volume by combining the vehicle-mounted battery power and the vehicle state; specifically:

[0083] (1) if the vehicle state is the working state and the vehicle battery power exceeds the preset first power threshold, the detection frequency of the vehicle loading volume is set to the first detection frequency;

[0084] (2) if the vehicle state is the non-working state or the vehicle battery power does not exceed the preset first power threshold, the detection frequency of the vehicle loading volume is set to the second detection frequency, and the first detection frequency is greater than the second detection frequency.

[0085] That is, the vehicle loading volume detection device compares the vehicle battery power with the preset first power threshold, wherein the preset first power threshold refers to the power at which the vehicle loading volume detection device normally works. If the vehicle battery power exceeds the preset first power threshold, the vehicle loading volume detection device starts the normal working mode, which means that the volume measurement module needs to be turned on and off according to the state machine logic due to the large power consumption, and the other modules of the system are in the always-on state. If the vehicle battery power does not exceed the preset first power threshold, the vehicle loading volume detection device starts the low-power working mode, which means that only the battery management module, the 4G+GPS module and the main control for reading the remaining power, device positioning and device control are used, and the functions of other modules are closed. For example, the preset first power threshold is 50% of the total power of the vehicle loading volume detection device.

[0086] In the embodiment, if the vehicle state is the working state and the vehicle battery power exceeds the preset first power threshold, the detection frequency of the vehicle loading volume is set to the first detection frequency. If the vehicle state is the non-working state or the vehicle battery power does not exceed the preset first power threshold, the detection frequency of the vehicle loading volume is set to the second detection frequency, and the first detection frequency is greater than the second detection frequency. Further, the detection frequency of the vehicle loading volume is set according to the vehicle battery power and the vehicle state, so that the data acquisition amount is more reasonable, and unnecessary power waste is reduced.

[0087] 204, controlling the preset volume detection device to detect the loading volume inside the vehicle compartment according to the detection frequency to obtain the vehicle loading volume.

[0088] The vehicle loading volume detection device controls the preset volume detection device to detect the loading volume inside the vehicle compartment according to the detection frequency to obtain the vehicle loading volume. That is, after the vehicle state, the volume measurement module will start periodic scanning inside the vehicle compartment, and through the analysis of the GPS data, the door opening and closing detection data and the volume measurement data, the scanning frequency is corrected and the state is exited.

[0089] The vehicle loading volume detection method in the application determines the vehicle state according to the vehicle position, vehicle motion speed and / or door opening and closing detection data, realizes the determination of the vehicle state according to the data collected by the vehicle itself, does not need to be connected for data interaction, reduces the cost and data processing amount of the equipment; then, the detection frequency of the vehicle loading volume is set according to the vehicle battery power and the vehicle state, since the vehicle state is related to the change of the vehicle loading volume, and the vehicle battery power is flexibly considered, the preset volume detection device is controlled to detect the vehicle loading volume according to the detection frequency, so that in the vehicle loading volume detection process, the power consumption of the equipment detection is reduced, and the change of the vehicle loading volume is accurately and effectively detected.

[0090] With reference to Figure 4 , Figure 4 is an embodiment flow diagram of the vehicle loading volume detection method provided in the application.

[0091] In some embodiments of the application, after step 201 determines the vehicle state according to at least one of the vehicle position, the vehicle motion speed and / or the door opening and closing detection data, the vehicle loading volume detection device sets the checking frequency of the vehicle position, the vehicle motion speed and / or the door opening and closing detection data, specifically including steps 301-303:

[0092] 301, if the vehicle state is a non-working state, the vehicle door opening and closing detection data is acquired according to a preset third detection frequency, and the vehicle battery power, the vehicle position and the vehicle motion speed are acquired according to a preset fourth detection frequency.

[0093] If the vehicle state is a non-working state, the vehicle loading volume detection device acquires the vehicle door opening and closing detection data according to a higher third detection frequency, and acquires the vehicle battery power, the vehicle position and the vehicle motion speed according to a lower fourth detection frequency, for example, when the vehicle state enters the non-working state, the door opening and closing detection module needs to be detected at a frequency f3, and the volume detection module and the vehicle positioning module can only maintain a lower frequency f4 scanning (f3>f4) to prevent not being collected at the state switching moment, thereby generating a larger error.

[0094] 302, if the door opening and closing detection data changes, the vehicle state is switched.

[0095] If the door opening and closing detection data changes, the vehicle loading volume detection device switches the vehicle state, that is, the collection of the vehicle battery power, the vehicle position, the vehicle motion speed and / or the door opening and closing detection data also consumes power in this embodiment, and the detection frequency is set according to the vehicle state, which can avoid the situation that the data update is not collected, and at the same time, the power consumption is reduced.

[0096] With referenceFigure 5 , Figure 5 is an embodiment flow diagram of the vehicle loading volume detection method provided in the embodiments of the present application, which is for adjusting the detection frequency according to the loading volume change rate.

[0097] In some embodiments of the present application, the vehicle loading volume detection device adjusts the detection frequency according to the loading volume change rate, specifically, comprising steps 401-403:

[0098] 401, obtaining at least two vehicle loading volumes detected according to the detection frequency, and calculating the loading volume change rate of the vehicle loading volume.

[0099] The vehicle loading volume detection device obtains at least two vehicle loading volumes detected according to the detection frequency, the vehicle loading volume detection device calculates the change amount of the at least two vehicle loading volumes, and the vehicle loading volume detection device divides the change amount by the time interval of detection to obtain the loading volume change rate of the vehicle loading volume.

[0100] 402, adjusting the detection frequency of the vehicle loading volume according to the loading volume change rate to obtain a new detection frequency.

[0101] The vehicle loading volume detection device adjusts the detection frequency of the vehicle loading volume according to the loading volume change rate to obtain a new detection frequency, specifically, comprising:

[0102] (1) If the loading volume change rate is less than or equal to a preset first change rate threshold, the detection frequency of the vehicle loading volume is reduced to obtain a new detection frequency;

[0103] (2) If the loading volume change rate is greater than the preset first change rate threshold and less than a preset second change rate threshold, the detection frequency of the vehicle loading volume is set to a new detection frequency;

[0104] (3) If the loading volume change rate is greater than or equal to the preset second change rate threshold, the detection frequency of the vehicle loading volume is increased to obtain a new detection frequency.

[0105] That is, in the present embodiment, the vehicle loading volume change rate is large, which indicates that the vehicle is in a working state, and multiple acquisitions can make the obtained vehicle loading volume more accurate. The vehicle loading volume change rate is small, which indicates that the vehicle is in a non-working state, and less acquisition can reduce the efficiency of power consumption. The vehicle loading volume change is normal, and the detection is performed according to the set frequency to save the rationality of the data.

[0106] 403, controlling the preset volume detection device to detect the loading volume inside the vehicle compartment according to the new detection frequency to obtain a new vehicle loading volume.

[0107] The vehicle loading volume amount detection device controls the preset volume detection apparatus to detect the loading volume inside the vehicle cabin according to a new detection frequency, and obtains a new vehicle loading volume. In this embodiment, after the initial determination of the detection frequency, the vehicle loading volume amount detection device can also adjust the detection frequency according to the vehicle loading volume change rate, so as to reduce the power consumption of the vehicle loading volume amount detection device while ensuring the accuracy and reasonableness of the data.

[0108] Referring to Figure 6 , Figure 6 is an embodiment flowchart of a vehicle loading volume amount detection method provided in this embodiment.

[0109] In some embodiments of the vehicle loading volume amount detection method, the method specifically includes steps 501-503:

[0110] 501, compare the vehicle battery power with a preset second power threshold.

[0111] The vehicle loading volume amount detection device compares the vehicle battery power with a preset second power threshold, wherein the preset second power threshold refers to a lower power in the vehicle loading volume amount detection device, for example, the preset second power threshold is 20% of the total power.

[0112] 502, if the vehicle battery power is less than or equal to the preset second power threshold, output a prompt information.

[0113] If the vehicle battery power is less than or equal to the preset second power threshold, the vehicle loading volume amount detection device outputs a prompt information, so that the user can timely charge or replace the battery.

[0114] 503, if the vehicle battery power is greater than the preset second power threshold, perform the step of determining the vehicle state according to at least one of the vehicle position, the vehicle motion speed and / or the opening / closing door detection data.

[0115] If the vehicle battery power is greater than the preset second power threshold, the vehicle loading volume amount detection device performs the step of determining the vehicle state according to at least one of the vehicle position, the vehicle motion speed and / or the opening / closing door detection data. In this embodiment, after the vehicle loading volume amount detection device obtains the vehicle battery power, the vehicle loading volume amount detection device first determines whether to charge, and further determines the vehicle state, so as to effectively reduce invalid operations.

[0116] Referring to Figure 7 , Figure 7is an embodiment flow diagram of the embodiment provided in the present application for determining the detection frequency according to the loading volume change rate in the vehicle loading volume detection method.

[0117] In some embodiments of the present application, the vehicle loading volume detection device can directly determine the detection frequency according to the vehicle loading volume change rate, specifically including steps 601-602:

[0118] 601, if the switch door detection data changes, the vehicle state is switched and the preset volume detection device is controlled to detect the loading volume inside the vehicle compartment to obtain the vehicle loading volume;

[0119] If the switch door detection data changes, the vehicle loading volume detection device switches the vehicle state and controls the preset volume detection device to detect the loading volume inside the vehicle compartment to obtain the vehicle loading volume, and the vehicle loading volume detection device or at least two vehicle loading volumes are calculated to obtain the loading volume change rate of the vehicle loading volume.

[0120] 602, according to the loading volume change rate of the vehicle loading volume, the vehicle battery power and the switched vehicle state, the detection frequency of the vehicle loading volume is set.

[0121] The vehicle loading volume detection device sets the detection frequency of the vehicle loading volume according to the loading volume change rate of the vehicle loading volume, the vehicle battery power and the switched vehicle state, so that the vehicle loading volume detection device can flexibly set the detection frequency of the vehicle loading volume according to various factors, reducing the waste of power and the amount of data processing.

[0122] For the convenience of understanding, a specific embodiment of a vehicle loading volume detection method is given in the embodiments of the present application, which includes:

[0123] After entering the operation state, the scanning frequency adjustment module will set the initial scanning frequency to the high frequency F1, and the GPS, door opening / closing detection, and volume measurement module will perform scans at this frequency. After obtaining the scan data, if it is determined that the GPS position has changed or the door is detected to be closed, the operation state module will be exited; otherwise, the scanning frequency adjustment module will accumulate the volume data for N cycles and adjust the scanning frequency: (1) If the standard deviation of the volume measurement data for N cycles is less than the preset value S and the volume change before and after the last scanning cycle is less than D, it means that the operation frequency is low in the current and previous N cycles. Therefore, the scanning frequency adjustment module will adjust the scanning frequency to the sub-high frequency F2 (F2 < F1). In this solution, multiple step frequencies Fx < Fx-1 < Fx-2... < F2 can be set. That is, when no operation has been performed for up to (x - 1)N cycles, the frequency can be adjusted to Fx; (2) If the standard deviation of the volume measurement data for N cycles is greater than the preset value S or the volume change before and after the last scanning cycle is greater than D, it means that there is an obvious change trend in the previous N cycles or the current volume. At this time, the scanning frequency needs to be adjusted to the highest frequency F1.

[0124] After entering the non-operation state, the volume measurement module and GPS can only maintain scans at the lower frequency f1, while the door opening / closing detection needs to be performed at the frequency f2 (f2 > f1) to prevent a large error from occurring at the state switching moment.
