In order to make the illustrations as concise as possible, not all structures are illustrated in the illustrations of this specification.

[0039] like Figures 1 to 6 As shown, the present invention provides a non-road mobile machinery license plate, the non-road mobile machinery license plate includes a license plate body 11, a solar panel 12, a positioning terminal module 13 and an RFID sensing chip 14; the license plate body 11 has a first surface and a second surface opposite to the first surface, the first surface is printed with a license plate number, the solar panel 12 is located on the first surface, the positioning terminal module 13 is located on the second surface and is electrically connected to the solar panel 12; the positioning terminal module 13 and the RFID sensing chip 14 are separated and spaced apart (that is, the two belong to their own independent modules) block); the positioning terminal module 13 includes a DC / DC transformer 131, a battery 132, a controller 133, an acceleration sensor 134, a positioning unit 135, a communication unit 136 and an RFID sensing unit 137, the controller 133 is connected to the battery 132, the acceleration sensor 134, the positioning unit 135, the communication unit 136 and the RFID sensing unit 137, the DC / DC transformer 131 is connected between the solar panel 12 and the battery 132, and the RFID sensing unit 137 is used to sense the information of the RFID sensing chip. The non-road mobile machinery license plate provided by the present invention can provide the real-time positioning and working information of the non-road mobile machinery, and can timely detect whether the license plate has been dismantled privately, and the real-time positioning terminal can draw power from the license plate itself without drawing power from the battery 132 of the vehicle, and is very safe and convenient to install and use. Applying the non-road mobile machinery license plate of the present invention to non-road mobile machinery helps prevent the theft of non-road mobile machinery and strengthen its management.

[0040] It should be specifically noted that the phrase "the positioning terminal module 13 and the RFID sensing chip 14 are arranged at intervals" means that when the positioning terminal module 13 and the RFID sensing chip 14 are installed on the same non-road mobile machinery, there should be a certain distance between them and they are physically separated. Through the mutual information sensing between the positioning terminal module 13 and the RFID sensing chip 14, it is possible to monitor in real time whether the license plate of the non-road mobile machinery has been removed, which will be further described in the following content.

[0041] As an example, the material of the license plate body 11 is a metal material, such as aluminum, stainless steel, or other alloy materials. The first surface includes a flat portion and a convex portion protruding from the surface of the flat portion, and the convex portion can be formed by stamping; the second surface includes a flat portion and a concave portion corresponding to the convex portion of the first surface; the solar panel 12 is located on the flat portion of the first surface, and the positioning terminal module 13 is located in the concave portion of the second surface. By providing the concave portion, it is beneficial to the installation and protection of the positioning terminal module 13.

[0042] In one example, as Figure 1 and Figure 2 shown, there is one solar panel 12, which is located on the flat portion of the first surface of the license plate body 11, such as above or below the license plate body 11. The convex portion of the first license plate body 11 is printed with the license plate number of the non-road mobile machinery, such as "Engineering Machinery Shanghai U3 - 00001". The second surface is the surface that is in contact with the non-road mobile machinery, while the first surface is the outward-facing surface.

[0043] In another example, as Figure 3 and Figure 4 shown, there are 2 solar panels 12. The convex portion is located in the middle of the first surface, and the license plate number is printed on the convex portion. The solar panels 12 are located on the flat portion of the first surface and on the upper and lower sides of the convex portion. Of course, in other examples, the number of solar panels 12 can also be 3 or more, and multiple solar panels can be arranged around the convex portion, which is not strictly limited in this embodiment. The solar panel 12 is used to supply power to the positioning terminal module 13. Preferably, the power of the solar panel 12 can not only ensure the normal operation of the positioning terminal module 13 but also fully charge the battery 132 of the positioning terminal module 13 within 2 hours.

[0044] The positioning terminal module 13 has the functions of recording and real-time remote transmission of multiple parameters such as the position of the machine, driving speed, acceleration amplitude, working conditions, etc., and also has an anti-disassembly function based on the RFID function. As an example, the thickness of the positioning terminal module 13 does not exceed 5mm, such as 3-5mm; the RFID sensing chip 14 stores the license plate information, and the RFID sensing chip 14 needs to be fixed on the body of the non-road mobile machinery at the same time. It cannot be used again after being removed. When the RFID sensing unit 137 in the positioning terminal module 13 can read the content stored in the RFID sensing chip 14, and the read content is consistent with the content in the preset program, it indicates that the license plate has not been removed, otherwise it has been removed.

[0045] As an example, the license plate body 11 is provided with a positioning hole 111 and a wiring hole (not shown), the wiring hole is used to electrically connect the solar panel 12 and the positioning terminal module 13 through a power supply line, the positioning hole 111 can be single or multiple, preferably multiple, such as 2, 3 or more, and the positioning hole 111 can be set on the left and right sides of the solar panel 12. The positioning hole 111 is used to fix the non-road mobile machinery license plate on the corresponding non-road mobile machinery.

[0046] As an example, the controller 133 includes but is not limited to an MCU, the positioning unit 135 includes but is not limited to a GPS / Beidou positioning unit, and the communication unit 136 includes but is not limited to a 4G / 5G communication unit. The solar panel 12 supplies power to the positioning terminal module 13 during the day and charges the battery 132 of the positioning terminal module 13; the DC / DC transformer 131 converts the voltage of the solar panel 12 into the voltage required by the battery 132, and the battery 132 supplies power to the positioning terminal module 13 at night, on cloudy days, and indoors; the controller 133, such as an MCU single-chip microcomputer (Single Chip Microcomputer), is the core of the positioning terminal module 13, and the program embedded in the MCU reads the data generated by the acceleration sensor 134, the voltage of the solar panel 12, the remaining power of the battery 132, the data generated by the positioning unit 135 (such as the GPS / Beidou positioning unit 135), and the data generated by the RFID sensing unit 137. The program embedded in the MCU calculates the working condition and data transmission frequency of the non-road mobile machinery according to the input, and finally sends the data parameters and the calculated parameters to the corresponding database center through the communication unit 136 (such as a 4G communication module). As an example, the acceleration sensor 134 should be able to sense the acceleration of the x, y, and z axes of the non-road mobile machinery, the MCU collects the acceleration of the z axis, and the positioning unit 135 obtains the longitude, latitude, and altitude information, as well as the moving speed. Figure 5 .

[0047] As an example, the non-road mobile machinery license plate also includes a QR code 15 located on the first surface of the license plate body 11. The QR code 15 stores basic technical information of the machinery to be managed and information of the machinery owner to facilitate on-site inspections by environmental management personnel.

[0048] Figure 6 The principle of anti-terminal disassembly of the non-road mobile machinery license plate of the present invention is illustrated. The license plate should be installed in a position that is not easily impacted and can be directly exposed to sunlight. The RFID sensing chip is installed on the peripheral plane of the non-road mobile machinery license plate. There should be no obstacles between the RFID sensing chip and the non-road mobile machinery license plate. When the actual distance between the RFID sensing chip and the non-road mobile machinery license plate exceeds a certain range, the non-road mobile machinery license plate sends a license plate disassembly signal, otherwise it sends a license plate not disassembly signal.

[0049] In order to make the technical solution and advantages of the present invention clearer, the working process of the positioning terminal module of the non-road mobile machinery license plate of the present invention is exemplified below. The following Table 1 shows the content, data type, data length and data definition sent by the positioning terminal module. The data items can meet the description of the working conditions of the monitored non-road mobile machinery. The use of this data mode is conducive to the unified management of large-scale non-road mobile machinery.

[0050] Table 1 Data content sent by the positioning terminal module

[0051]

[0052] In one example, when the absolute value of the G value of the acceleration sensor of the non-road mobile machinery for 1 second in the past 10 seconds is greater than 0.1, it indicates that the vehicle is started, regardless of the voltage of the solar panel, and the sending frequency is once per second; -1 The data of the previous second of the current value is performed 10 times. -1 All data of the previous 10 seconds can be obtained; when the absolute value of the G value of the acceleration sensor in the past 10 seconds is less than 0.1, it means that the vehicle is stationary. If the voltage of the solar panel is lower than 5V, the transmission frequency is once every 10 minutes, and once every minute when it is higher than 5V. The algorithm is shown in the following table:

[0053] Figure 2 Monitoring data sending frequency F1 table

[0054]

[0055] How to determine the operating status of the monitored non-road mobile machinery to accurately grasp the operating status of the non-road mobile machinery is an important function of the positioning terminal module. When the 30-second sliding average of the G value of the acceleration sensor is greater than the calculation result of the real-time calculated C (Speed) function, the non-road mobile machinery is in action mode. The sliding average is the average value of multiple continuous m-item sequences calculated from a time series with n items. C (Speed) = C1*speed 2 +C2*speed+C3 (empirical formula), speed is the sliding average of the previous 30 seconds of data. When it is less than C (speed), for example, when the walking speed is less than 5km / h, it is idling, and when it is higher than 5km / h, it is walking. The corresponding relationship is shown in the following table:

[0056] Table 3 Operating status of monitored non-road mobile machinery

[0057]

[0058] In order to make the non-road mobile machinery license plate as light as possible, the power of the solar panel is limited, which also determines that the capacity of the battery of the positioning terminal module is limited. When encountering cloudy days, nights and indoor working environments, the positioning terminal module can only rely on batteries for power supply. Therefore, by adjusting the data transmission frequency, it is possible to effectively save electricity and increase the service life of the positioning terminal module.

[0059] The present invention also provides a non-road mobile machinery, the non-road mobile machinery includes a non-road mobile machinery license plate as described in any of the above schemes, the RFID sensing module and the RFID sensing chip of the non-road mobile machinery license plate are arranged at intervals on the non-road mobile machinery, for example, the RFID sensing chip is installed on the peripheral plane of the non-road mobile machinery license plate, there should be no obstacles between the RFID sensing chip and the non-road mobile machinery license plate, when the distance between the RFID sensing chip and the non-road mobile machinery license plate exceeds a certain range, the non-road mobile machinery license plate sends a license plate removal signal, otherwise it sends a non-removed signal. Please refer to the above content for the introduction of the non-road mobile machinery license plate, which will not be repeated for the purpose of brevity. The installation of the non-road mobile machinery license plate facilitates the monitoring and management of the non-road mobile machinery. The non-mobile road machinery includes various types of non-road mobile diesel machinery in use, including agricultural machinery, engineering machinery and port machinery, such as excavators, bulldozers, loaders, rollers, pavers, graders, slotting machines, pile driving machinery, forklifts, cranes, loading and unloading machinery, tractors, etc.

[0060] The present invention also provides a non-road mobile machinery management method, which is performed according to the non-road mobile machinery license plate described in any of the above-mentioned schemes. The positioning terminal module sends information to the RFID sensing chip, and determines whether the non-road mobile machinery license plate has been removed based on the information fed back by the RFID sensing chip.

[0061] As an example, the information sent by the positioning terminal module to the RFID sensing chip includes information collection time, whether the RFID sensing chip is removed, solar panel voltage, its own working status, positioning data, and the moving speed and acceleration amplitude of the non-road mobile machinery in which it is located.

[0062] As an example, the positioning terminal module adjusts the frequency of sending information to the RFID sensing chip according to the acceleration amplitude of the non-road mobile machinery and / or the voltage of the solar panel.

[0063] As an example, when the non-road mobile machinery is in the starting state, the positioning terminal module sends information at a frequency of 1 to 5 seconds per time, preferably 1 second per time; when the non-road mobile machinery is stationary and the voltage of the solar panel is lower than 5V, the frequency of sending information is 5 to 10 minutes per time, preferably 10 minutes per time, and when the voltage is higher than 5V, the frequency of sending information is 1 to 4 minutes per time, preferably 1 minute per time. This ensures good monitoring functions while greatly saving battery energy and extending the service life of the positioning terminal module.

[0064] In a further example, the 30-second sliding average of the G value of the acceleration sensor of the non-road mobile machinery is greater than C(Speed)=C1*speed 2 +C2*speed+C3, the non-road mobile machinery is judged to be in the starting state, otherwise it is judged to be in the stationary state, wherein speed is the sliding average of the data of the non-road mobile machinery in the previous 30 seconds, and C1, C2 and C3 are empirical values ​​determined by the type of the non-road mobile machinery. For example, in one example, C1 is 0.0015, C2 is 0.0396, and C3 is 1.0231.

[0065] As described above, the present invention provides a non-road mobile machinery license plate and a non-road mobile machinery management method. The non-road mobile machinery license plate includes a license plate body, a solar panel, a positioning terminal module and an RFID sensing chip; the license plate body has a first surface and a second surface opposite to the first surface, the first surface is printed with a license plate number, the solar panel is located on the first surface, the positioning terminal module is located on the second surface and is electrically connected to the solar panel; the positioning terminal module and the RFID sensing chip are arranged at intervals; the positioning terminal module includes a DC / DC transformer, a battery, a controller, an acceleration sensor, a positioning unit, a communication unit and an RFID sensing unit, the controller is connected to the battery, the acceleration sensor, the positioning unit, the communication unit and the RFID sensing unit, the DC / DC transformer is connected between the solar panel and the battery, and the RFID sensing unit is used to sense the information of the RFID sensing chip.
