In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0019] According to one aspect of an embodiment of the present application, a vehicle positioning device is provided, wherein the vehicle positioning device is installed on a vehicle to be monitored. Figure 1 FIG. 1 is a schematic block diagram of a vehicle positioning device according to an embodiment of the present application. Figure 1 As shown, the device includes: a wireless communication module, a control module 1 and a positioning module 3; the control module 1 is connected to the wireless communication module and the positioning module 3 respectively; the wireless communication module is used to receive remote monitoring request information and transmit the remote monitoring request information to the control module 1; the control module 1 is used to obtain the status information of the vehicle to be monitored by at least using the positioning module 3 after receiving the monitoring request information, and, after obtaining the status information, send the status information to the corresponding terminal device; wherein the monitoring request information includes remote monitoring request information; the status information includes the location information of the vehicle to be monitored; wherein, when the monitoring request information is remote monitoring request information, the control module 1 sends the status information to the corresponding terminal device in the following manner: using the wireless communication module to send the status information to the corresponding terminal device.

[0020] In the solution of this example, the wireless communication module can transmit the remote monitoring request information to the control module 1. The wireless communication module can be a module that performs wireless communication through any one or several communication protocols that are currently available or will be developed in the future. The communication protocol includes but is not limited to the Bluetooth communication protocol, the WIFI communication protocol, the LTE communication protocol, etc., and this example does not limit this. In some embodiments, the wireless communication module can perform wireless communication through multiple communication protocols. In this case, the wireless communication module can be composed of multiple independent communication modules, and the multiple communication modules correspond one to one with the multiple communication protocols.

[0021] In the solution of this example, the positioning module 3 is used to obtain the positioning information of the current vehicle to be monitored. The high positioning module 3 can adopt any chip that can realize the positioning function, which is currently available or developed in the future. For example, the positioning module 3 can be a GPS chip. For another example, the positioning module 3 can be a chip that uses a cellular network for positioning. In a specific embodiment, the positioning module 3 can be a TD1050GPS chip of Taidou.

[0022] As described above, the control module 1 is used to obtain the status information of the vehicle to be monitored by at least using the positioning module 3 after receiving the monitoring request information, and after obtaining the status information, send the status information to the corresponding terminal device. In other words, the control module 1 can obtain the status information of the vehicle to be monitored after receiving the monitoring request information, and send the status information to the corresponding terminal device. It can be understood that the corresponding terminal device is the terminal device that sends the monitoring request information. The terminal device includes but is not limited to a mobile phone, a tablet computer, etc.

[0023] In some embodiments, the control module 1 may be composed of multiple modules. It is understandable that the more pins the control module 1 has, the higher its cost may be. In the solution of this embodiment, the number of pins can be expanded by setting up multiple modules, so that modules with a large number of pins and high costs can be replaced by multiple modules with a small number of pins and low costs, which helps to reduce production costs. In a specific embodiment, the control module 1 may include a main control module 1 and an auxiliary control module 1, the main control module 1 is a STM32L496VGY6PTR single-chip microcomputer, the auxiliary control module 1 is a STM32G0B1RET6 single-chip microcomputer, and the main control module 1 uses the SPI protocol, I 2 C protocol, etc. to realize the control of the positioning module 3, the wireless communication module, etc.

[0024] The device of the above technical solution has a simple overall structure and is easy to use. It can locate the monitored vehicle based on the monitoring request information (i.e., remote monitoring request information) remotely issued by the user. This remote interaction method can facilitate the user to obtain the vehicle's location information in real time, which helps to improve the safety of the vehicle and at the same time helps to improve the user's experience.

[0025] For example, Figure 1 As shown, the device also includes an acceleration module 4; the status information also includes acceleration information of the vehicle to be monitored; the control module 1 obtains the status information of the vehicle to be monitored in the following manner: respectively using the positioning module 3 and the acceleration module 4 to obtain the status information, and after obtaining the status information, sending the status information to the corresponding terminal device.

[0026] It can be understood that the positioning module 3 can be used to obtain the positioning information of the current monitored vehicle and transmit it to the control module 1; the acceleration module 4 can be used to obtain the acceleration information of the current monitored vehicle and transmit the acceleration information to the control module 1.

[0027] Optionally, the acceleration module 4 may select any existing or future developed chip that can be used to measure acceleration, for example, a 3D acceleration sensor chip LIS3DH may be used.

[0028] In the solution of this example, the vehicle positioning device can also determine the acceleration information of the vehicle and feed it back to the user. Thus, the device can simultaneously obtain the position information and acceleration information of the vehicle, so that the user can understand the real-time position and real-time status of the vehicle, which helps to further improve the safety of the vehicle.

[0029] Exemplarily, the control module 1 obtains the state information by using the positioning module 3 and the acceleration module 4 respectively in the following manners: enabling the positioning module 3 to obtain the position information; enabling the acceleration module 4 to obtain the acceleration information.

[0030] Optionally, the control module 1 is further used to control the positioning module 3 and the acceleration module 4 to be turned off after receiving the position information and the acceleration information.

[0031] In the solution of this example, when the control module 1 receives the monitoring request information, it can send an enable signal to the positioning module 3 and the acceleration module 4 to enable the positioning module 3 and the acceleration module 4 to start working. When working, the positioning module 3 and the acceleration module 4 can respectively obtain the position information and acceleration information of the vehicle to be monitored, and transmit them to the control module 1. After receiving the position information and the acceleration information, the control module 1 can send the position information and the acceleration information to the corresponding terminal device.

[0032] In the above technical solution, the control module 1 can control the positioning module 3 and the acceleration module 4 to start working when receiving the monitoring request information, and when not receiving the monitoring request information, the positioning module 3 and the acceleration module 4 can be in a closed state. This method helps to save energy consumption and extend the use time and service life of the device.

[0033] Exemplarily, the terminal device includes an on-board computer, and the control module 1 is connected to the on-board computer via the communication interface of the on-board computer; the monitoring request information also includes local monitoring request information sent by the on-board computer to the control module 1 via the communication interface; wherein, when the monitoring request information is local monitoring request information, the control module 1 sends the status information to the corresponding terminal device in the following manner: sending the status information to the on-board computer via the communication interface.

[0034] In the solution of this example, the control module 1 is connected to the vehicle-mounted computer via the communication interface of the vehicle-mounted computer. In some embodiments, the communication interface may be an OBD interface of the vehicle-mounted computer.

[0035] Optionally, the control module 1 can communicate with the vehicle computer through communication methods such as CAN protocol, J1850 protocol, K / L Line communication protocol, etc. The specific communication method can be selected according to actual working conditions, and this application does not limit this.

[0036] In the solution of this example, the control module 1 is connected to the vehicle-mounted computer through the communication interface of the vehicle-mounted computer. In this case, the user can send local monitoring request information through the vehicle-mounted computer. After receiving the local monitoring request information, the control module 1 obtains the status information of the vehicle to be monitored, and transmits the status information to the vehicle-mounted computer via the communication interface to realize real-time positioning and status query of the vehicle.

[0037] In the embodiment where the control module 1 includes the main control module 1 and the auxiliary control module 1, the wireless communication module, the positioning module 3 and the acceleration module 4 are all connected to the main control module 1, the main control module 1 is connected to the auxiliary control module 1, and the auxiliary control module 1 is connected to the on-board computer through the communication interface of the on-board computer. In this embodiment, the on-board computer can transmit the local monitoring request information to the auxiliary control module 1 through communication methods such as the CAN protocol and the J1850 protocol, and the auxiliary control module 1 can transmit the local monitoring request information to the main control module 1 through serial communication. After the main control module 1 searches for the status information of the vehicle to be monitored, it transmits the status information to the auxiliary control module 1 through serial communication, and the auxiliary control module 1 transmits the status information to the on-board computer through communication methods such as the CAN protocol and the J1850 protocol to complete the real-time positioning and status query of the vehicle to be monitored.

[0038] In the above technical solution, the control module 1 is connected to the onboard computer through the communication interface of the onboard computer. Therefore, the user can directly use the onboard computer to send local monitoring request information to query the real-time positioning and status of the monitored vehicle, or can remotely send remote monitoring request information to query the real-time positioning and status of the monitored vehicle. In other words, the device supports obtaining the status information of the monitored vehicle through a variety of interactive methods, which can facilitate the user's use and help improve the user's experience.

[0039] For example, Figure 1 As shown, the wireless communication module includes a cellular network communication module 2 and / or a Bluetooth communication module 5. Figure 1 In the illustrated embodiment, the wireless communication module may include a cellular network communication module 2 and a Bluetooth communication module 5. In some embodiments, the cellular network communication module 2 may be an LTE module. In a specific embodiment, the LTE module adopts Telit's ME910G1 series. The Bluetooth communication module 5 adopts ST's BlueNRG-234.

[0040] In such Figure 1 In the illustrated embodiment, the cellular network communication module 2 is connected to a card slot 6 for inserting a SIM card.

[0041] In some embodiments, the wireless communication module includes a cellular network communication module 2. In this embodiment, when a user has a remote positioning requirement, a terminal device (such as a mobile phone, a tablet computer, etc.) can be used to send a remote monitoring request message to the vehicle positioning device through a cellular network. The cellular network communication module 2 of the vehicle positioning device receives the remote monitoring request message and sends the remote monitoring request message to the control module 1. After the control module 1 obtains the status information of the vehicle to be controlled, the status information can be sent to the terminal device through the cellular network communication module 2 so that the user can view the location and acceleration information of the vehicle to be controlled.

[0042] In some embodiments, the wireless communication module includes a Bluetooth communication module 5. In a specific embodiment, when the user is close to the vehicle (not exceeding the effective communication distance of the Bluetooth communication module 5) or the user is in the vehicle, the terminal device can be connected to the vehicle positioning device via Bluetooth. When the user has a positioning requirement, the terminal device (such as a mobile phone, tablet computer, vehicle-mounted computer, or any other Bluetooth-enabled device) can be used to send remote monitoring request information to the vehicle positioning device via Bluetooth transmission. The Bluetooth communication module 5 of the vehicle positioning device receives the remote monitoring request information and sends the remote monitoring request information to the control module 1. After obtaining the status information of the vehicle to be controlled, the control module 1 can send the status information to the terminal device via the Bluetooth communication module 5 so that the user can view the location and acceleration information of the vehicle to be controlled.

[0043] Optionally, the device may also include a Bluetooth status indicator light for displaying the working status of the Bluetooth module, a network status indicator light for displaying the working status of the cellular network communication module 2, and a positioning status indicator light for displaying the working status of the positioning module 3, and the control module 1 is connected to the Bluetooth status indicator light, the network status indicator light, and the positioning status indicator light, respectively. In some embodiments, the colors of the three status indicator lights may be different. For example, the Bluetooth status indicator light is a blue light, the network status indicator light is a green light, and the positioning status indicator light is an amber light. In the scheme of this embodiment, the control module 1 can control the corresponding status indicator light to turn on when the corresponding module is turned on, and control the corresponding status indicator light to turn off when the corresponding module is turned off, so that the user can timely understand the working status of the corresponding module according to the status indicator light, which helps to improve the user experience.

[0044] The device of the above technical solution can send and receive information through cellular networks and / or Bluetooth communications. This method of positioning the vehicle through Internet of Things control can facilitate users to obtain vehicle positioning information, improve the real-time nature of positioning information, and help improve the user experience.

[0045] In a specific embodiment of the present application, the control module 1 includes a main control module 1 and an auxiliary control module 1. The main control module 1 is mounted on a circuit board (which may be referred to as an LTE board) in which an LTE module is embedded. The acceleration sensor, the card slot 6, the buzzer 8, the indicator light module 7 described below, and the switches corresponding to each functional module are all mounted on the LTE board.

[0046] The auxiliary control module 1 is mounted on the OBD board, and the GPS module, the Bluetooth communication module 5, the CAN chip for realizing the CAN function, and the circuit for realizing the K / L Line and J1850 communication functions are all mounted on the OBD board. Those skilled in the art can understand the circuit structure for realizing the K / L Line and J1850 communication functions, and will not be described in detail.

[0047] The LTE board is equipped with a separate GPIO port to communicate with the OBD board through a connector to achieve the connection of each module and the realization of functions. Both the LTE board and the OBD board have test points for downloading / upgrading software.

[0048] Exemplarily, the device further includes a power supply component, which is respectively connected to the wireless communication module, the control module 1 and the positioning module 3 .

[0049] It can be understood that the power supply component is used to supply power to each module in the device so that it can work normally. Figure 2 In the illustrated embodiment, the power supply assembly is respectively connected to the control module 1 , the positioning module 3 , the cellular network communication module 2 , the Bluetooth communication module 5 and the acceleration module 4 .

[0050] It can be understood that in order to facilitate the various functional modules (such as Figure 1 The control module 1 can control the positioning module 3, the cellular network communication module 2, the Bluetooth communication module 5 and the acceleration module 4 in the control module 1, a switch can be set between the power supply component and the corresponding functional module, and the control module 1 can be connected to the switch corresponding to each functional module respectively, so as to control the corresponding functional module. For example, in the above embodiment in which the control module 1 enables the positioning module 3, the control module 1 can be connected to the switch corresponding to the positioning module 3 (referred to as the first switch for easy distinction). In this embodiment, the control module 1 can enable the positioning module 3 by turning on the first switch, and control the positioning module 3 to be turned off by turning off the first switch.

[0051] Optionally, a voltage stabilizer may be provided between the power supply assembly and each module to ensure voltage stability.

[0052] Optionally, the power supply component is connected to a delay circuit module 14, and supplies power to the subsequent circuit via the delay circuit module 14. This embodiment can prevent a large spike voltage from damaging the subsequent circuit module when power is suddenly turned on by providing the delay circuit module 14, which helps to improve the safety of the device.

[0053] The above technical solution uses one power supply component to supply power to multiple modules at the same time, which helps to simplify the circuit structure and reduce costs.

[0054] Exemplarily, the power supply component includes: a power supply interface 9, a battery 12 and a power selection module 13, the power supply interface 9 and the battery 12 are both connected to the power selection module 13; the power selection module 13 is respectively connected to the wireless communication module, the control module 1 and the positioning module 3; wherein the power selection module 13 is used to: when there is a power supply connected to the power supply interface 9, use the power supply connected to the power supply interface 9 for power supply; when there is no power supply connected to the power supply interface 9, use the battery 12 for power supply.

[0055] Optionally, the power supply interface 9 can be connected to the onboard computer of the vehicle to be monitored, so as to use the onboard computer to power the device. Of course, the power supply interface 9 can also be directly connected to the battery of the vehicle to be monitored, and this application does not limit this.

[0056] In the solution of this example, there is power access to the power supply interface 9, which means that the power connected to the power supply interface 9 can power the device through the power supply interface 9. No power access to the power supply interface 9 means that the power connected to the power supply interface 9 cannot power the device through the power supply interface 9, or the power supply interface 9 is not connected to the power supply. Take the connection between the power supply interface 9 and the on-board computer as an example. In this embodiment, after the on-board computer is turned on, the on-board computer can power the device, and at this time, there is power access to the power supply interface 9. After the on-board computer is turned off, the on-board computer is in an off state, and at this time, there is no power access to the power supply interface 9.

[0057] Optionally, a voltage reduction module 10 may be provided between the power supply interface 9 and the power selection module 13 so that the connected power supply voltage can meet the use requirements of the subsequent circuit. The voltage reduction module 10 may be a BUCK chip.

[0058] Optionally, the device may also include a power indicator light, which is connected to the control module 1. The control module 1 is also used to: determine the current power supply by using the power selection module 13, and, when the current power supply is the power supply connected to the power supply interface 9, control the luminous color of the power indicator light to be a first preset color (e.g., red), and when the current power supply is the battery 12, control the luminous color of the power indicator light to be a second preset color (e.g., yellow), wherein the first preset color is different from the second preset color. This scheme uses different colors of power indicator lights to display different power supplies, which helps users view the power supply status of the device and improves the user experience. It also helps to promptly discover power supply anomalies, so that users can maintain the device in a timely manner. For example, if the on-board computer is turned on, but the luminous color of the power indicator light is the second preset color, the power supply status is abnormal at this time, which may be due to the fact that the power connection cable between the device and the on-board computer is not properly plugged in. In this case, the user can promptly discover the anomaly and perform maintenance, which helps to ensure the working reliability of the device.

[0059] In the above technical solution, the power selection module 13 can select the power supply mode according to the power access status at the power supply interface 9 (i.e., power supply is provided by the power supply connected to the power supply interface 9 or by the battery 12). In this way, it can be ensured that the device can also accurately locate when the monitored vehicle is not started, and when the monitored vehicle is started, the monitored vehicle can be used to power the device, which helps to extend the battery life of the device and the service life of the battery 12.

[0060] Exemplarily, the control module 1 is connected to the power selection module 13 ; the control module 1 is further used to obtain the remaining power of the battery 12 using the power selection module 13 .

[0061] In some embodiments, the device may further include a power indicator light, and the control module 1 may further be used to control the power indicator light to flash when the remaining power of the battery 12 is less than or equal to a preset power threshold value, so as to remind the user. Figure 1 As shown, the device may further include a buzzer 8, and the control module 1 may further be used to: when the remaining power of the battery 12 is less than or equal to a preset power threshold, control the buzzer 8 to emit a prompt sound to remind the user. In some other embodiments, the control module 1 may further be used to: send the remaining power of the battery 12 to the user's terminal device so that the user can understand the usage of the battery 12.

[0062] In such Figure 1 In the illustrated embodiment, the device includes an indicator light module 7, on which a plurality of indicator lights may be provided, including but not limited to the power indicator light in this example and the status display light, power indicator light, etc. described above.

[0063] Optionally, the battery 12 may be a rechargeable battery 12 or a non-rechargeable battery 12, i.e., a disposable battery 12. In the solution of this example, the control module 1 may obtain the remaining power of the battery 12. In this way, when the remaining power is insufficient, the user may be reminded to charge or replace the battery 12 or activate an automatic charging mode (such as the embodiment of charging the battery 12 below), which may ensure that the device can work stably for a long time, and help improve the reliability of the device and the user experience.

[0064] Exemplarily, the battery 12 is a rechargeable battery 12; the control module 1 is also used to: use the power selection module 13 to determine the current power supply, and, when the current power supply is the power supply connected to the power supply interface 9 and the remaining power is less than or equal to a preset power threshold, use the power supply connected to the power supply interface 9 to charge the battery 12.

[0065] Optionally, the device may also include a charging chip 11, the control module 1 is connected to the charging chip 11, and the power supply interface 9 is connected to the battery 12 via the charging chip 11; the control module 1 specifically charges the battery 12 using the power supply connected to the power supply interface 9 in the following manner: enable the charging chip 11 to charge the battery 12 using the power supply connected to the power supply interface 9.

[0066] Optionally, the control module 1 can also be used to: when the remaining power of the battery 12 reaches the capacity of the battery 12, the power supply connected to the power supply interface 9 stops charging the battery 12. In the above embodiment including the charging chip 11, the control module 1 can control the charging chip 11 to be turned off so that the power supply connected to the power supply interface 9 stops charging the battery 12.

[0067] The above technical solution can use the power supply connected to the power supply interface 9 to charge the battery 12 when the current power supply is the power supply connected to the power supply interface 9 and the remaining power of the battery 12 is less than or equal to the preset power threshold. In this way, the battery 12 can be automatically charged without the user manually charging the battery 12. This is beneficial to improving the battery life of the device, simplifying the charging operation, and improving the user experience.

[0068] Combine the following Figure 2 A power supply component of a specific embodiment of the present application is introduced in detail. It can be understood that Figure 2 The connection between the functional modules is mainly to show the connection between the power supply component and each functional module, so the connection between the functional modules is omitted. The connection between the functional modules has been described in detail above and will not be repeated here.

[0069] exist Figure 2In the embodiment, the power supply interface 9 is used to connect the on-board computer. The power supply interface 9 is connected to the power selection module 13 and the charging chip 11 via the step-down module 10. The charging chip 11 is connected to the charging end of the battery 12. The battery 12 is connected to the power selection module 13. The power supply port of the power selection module 13 is connected to the delay circuit module 14, and is respectively connected to the first voltage regulator 15, the second voltage regulator 16, the third voltage regulator 17 and the power switch 18 via the delay circuit module 14.
