[0026] The following is an example of a vehicle provided by the present application.
[0027] Figure 1 An example of a vehicle provided by the present application is shown, as shown in Figure 1 The vehicle 100 provided by the present application includes a detection controller 101, a signal detection assembly 102 arranged on the vehicle body and a position reminder 103. The signal detection assembly 102 includes m signal detectors, and the detection controller 101 calculates the specific position of the electronic device arranged on the vehicle body by using the trilateration method. Therefore, at least three signal detectors arranged on the vehicle body are needed to detect the signal strength of the electronic device, so m is a positive integer greater than or equal to 3. Among them, the electronic device refers to the monitoring and listening device illegally installed on the vehicle body, such as positioning module, listener, camera, etc.
[0028] The position reminder 103 is in communication connection with the detection controller 100, and the detection controller 100 is in communication connection with the m signal detectors. The communication connection can be hard-wired connection or wireless connection. The m signal detectors are arranged at different positions of the vehicle body, that is, the arrangement position of each signal detector on the vehicle body is different. For example, the signal detector has five, which are the first to fifth signal detectors, as shown in Figure 2 Figure 2 Another exemplary schematic diagram of a vehicle provided by the present application is shown, the first signal detector 1021 is arranged in the front cabin, the second signal detector 1022 is arranged in the driver's seat, the third signal detector 1023 is arranged in the rear seat (for example, under the middle seat in the rear seat), the fourth signal detector 1024 is arranged in the trunk, and the fifth signal detector 1025 is arranged on the top of the vehicle cabin (for example, on the top of the vehicle cabin above the rear seat). Among them, any one of AVR series single-chip microcomputer, STM32 series single-chip microcomputer, ESP32 single-chip microcomputer, etc. can be selected as the detection controller, for example, the single-chip microcomputer with model number STM32F4 is selected as the detection controller.
[0029] For each signal detector Gi in the m signal detectors, the signal detector Gi is used to receive the signal strength of the electronic device arranged on the vehicle body, and send the signal strength received by the signal detector Gi to the detection controller. The specific connection relationship between the signal detector Gi and the detection controller is shown in Figure 2 Figure 2 The connection relationship between the signal detector and the detection controller is shown, the signal detector Gi includes a receiving antenna, an amplifier, a filter, a mixer and an analog-to-digital converter, which are connected in sequence, and the analog-to-digital converter is connected with the signal input interface of the detection controller. If the vehicle body is installed with an electronic device, the receiving antenna receives the radio frequency signal (belonging to analog signal) of the electronic device, the amplifier amplifies the radio frequency signal received by the receiving antenna, and outputs the amplified radio frequency signal to the filter, the filter filters the amplified radio frequency signal, and outputs the filtered radio frequency signal to the mixer, the mixer mixes the filtered radio frequency signal with the reference signal generated by the local oscillator to generate an intermediate frequency signal, and outputs the intermediate frequency signal to the analog-to-digital converter, the analog-to-digital converter converts the intermediate frequency signal into a digital signal, and the digital signal includes the signal strength of the electronic device, the analog-to-digital converter sends the digital signal to the detection controller, and the detection controller can receive the signal strength sent by the signal detector Gi.
[0030] The detection controller receives the signal strength sent by the signal detector Gi, substitutes the signal strength sent by the signal detector Gi into a logarithmic distance path loss calculation formula, obtains the distance between the signal detector Gi and the electronic device, and solves the position coordinate of the electronic device on the vehicle body according to the distance and the stored first position coordinate of the signal detector Gi on the vehicle body. In order to facilitate distinction, the position coordinate of the electronic device on the vehicle body is referred to as a second position coordinate, and the detection controller sends the second position coordinate to the position reminder. After the position reminder receives the second position coordinate sent by the detection controller, the position reminder outputs the position reminding information of the second position coordinate of the electronic device installed on the vehicle body, and the user can clearly determine the specific position of the electronic device installed on the vehicle body through the position reminding information.
[0031] Taking three signal detectors as an example, it is assumed that the signal detectors include a first signal detector, a second signal detector and a third signal detector, and the first position coordinates of the first signal detector, the second signal detector and the third signal detector are stored in the memory of the detection controller with the centroid of the vehicle as the origin. The first position coordinates of the first signal detector, the second signal detector and the third signal detector are P1(x1, y1, z1), P2(x2, y2, z2) and P1(x3, y3, z3) in turn. The logarithmic distance path loss calculation formula is: RSSI=A-10×n×lg(d), where RSSI represents the signal strength, A is a constant, representing the signal strength at a reference distance, n is a path loss index, representing the loss that increases with the increase of distance, and d represents the straight-line distance between the signal detector and the electronic device, in meters.
[0032] For example, the signal strengths received by the first signal detector, the second signal detector and the third signal detector are RSSI-1, RSSI-2 and RSSI-3 respectively. The detection controller substitutes RSSI-1, RSSI-2 and RSSI-3 into the above logarithmic distance path loss calculation formula respectively, obtains the straight-line distance between the first signal detector and the electronic device, represented as d1, the straight-line distance between the second signal detector and the electronic device, represented as d2, and the straight-line distance between the first signal detector and the electronic device, represented as d3. Then, based on the three-edge measurement principle, the detection controller constructs an equation group through P1-P3 and d1-d3, the second position coordinate of the electronic device on the vehicle body is represented as P(x, y, z), and the constructed equation group is as follows:
[0033] (x-x1) 2 +(y-y1) 2 +(z-z1) 2 =d1 2 ;
[0034] (x-x2)2 +(y-y2) 2 +(z-z2) 2 =d2 2 ;
[0035] (x-x3) 2 +(y-y3) 2 +(z-z3) 2 =d3 2 ;
[0036] Since P1-P3 and d1-d3 are known values, the above equations are solved to obtain x, y and z, thereby obtaining the second position coordinates of the electronic device on the vehicle body. If m is greater than 3, the constructed equation set has multiple if the second position coordinates of the electronic device on the vehicle body are obtained, the average of the multiple second position coordinates is obtained to obtain the final second position coordinates of the electronic device on the vehicle body.
[0037] With the center of mass of the vehicle as the original center, each coordinate point on the vehicle body corresponds to a specific position on the vehicle body. After obtaining the second position coordinates of the electronic device on the vehicle body, the specific position corresponding to the second position coordinates is further obtained, and the second position coordinates are sent to the position reminder by the detection controller. The position reminder outputs the position reminding information of the electronic device installed on the vehicle body according to the second position coordinates, thereby reminding the user that the monitoring and listening device is illegally installed on the vehicle, and informing the user of the specific installation position of the monitoring and listening device on the vehicle body, so as to facilitate the user to timely remove it. If the detection controller does not detect the monitoring and listening device, the user will be reminded to use the vehicle with peace of mind. The position reminder includes a loudspeaker and / or a multimedia host, and the position reminding information can be voice broadcast through the loudspeaker or text and image display through the multimedia host.
[0038] The embodiments of the present application set up signal detectors at different positions of the vehicle, receive the signal strength of the electronic device illegally installed on the vehicle by using the signal detectors, then calculate the position coordinates of the electronic device on the vehicle by the detection controller, and output the reminding information of the position coordinates of the electronic device by the position reminder. Not only is it realized that whether the monitoring and listening device is installed in the vehicle is listened, but also the specific installation position of the monitoring and listening device in the vehicle is located, which helps the user to quickly find the potential safety hazards on the vehicle and is beneficial to reduce the risk of user privacy leakage.
[0039] In a possible implementation, the position reminder includes a multimedia host, and a display screen of the multimedia host is capable of displaying a three-dimensional vehicle model of the vehicle that is constructed in advance, each coordinate point in the three-dimensional vehicle model has a one-to-one mapping relationship with each coordinate point on the vehicle body, for example, a steering wheel coordinate point in the three-dimensional vehicle model corresponds to a steering wheel coordinate point on the vehicle body. After the second position coordinate is sent to the multimedia host by the detection controller, the multimedia host acquires the second position coordinate, and then finds a third position coordinate that has a mapping relationship with the second position coordinate from the three-dimensional vehicle model, the position corresponding to the third position coordinate in the three-dimensional vehicle model is the position of the virtual identifier of the electronic device, so that the virtual identifier of the electronic device is displayed at the position corresponding to the third position coordinate in the three-dimensional vehicle model, and the user can intuitively see where the electronic device is installed on the vehicle body through the three-dimensional vehicle model. As shown in Figure 3 Figure 3 A schematic diagram of the three-dimensional vehicle model is shown, 200 represents the three-dimensional vehicle model, P represents the virtual identifier of the electronic device, and the electronic device is installed under the left rear seat. In addition, the user can also see the setting positions of the signal detectors on the three-dimensional vehicle model, Figure 2 1-5 represent the setting positions of the five signal detectors.
[0040] In a possible implementation, the multimedia host is further configured to output tutorial information for guiding the user to remove the electronic device. Considering that some users do not understand the structure of the vehicle, after learning that the electronic device is installed on the vehicle, there is a case that the user removes the electronic device by himself. In order to avoid that the user removes the electronic device by himself and causes damage to the vehicle, the display screen of the multimedia host outputs the tutorial information for guiding the user to remove the electronic device, the tutorial information includes a video tutorial and / or a text tutorial, so as to guide the user to correctly disassemble the components on the vehicle, so as to find the electronic device and avoid causing damage to the components of the vehicle. The user does not need to hire professional vehicle maintenance personnel to remove the electronic device, and the hiring cost is saved.
[0041] In a possible implementation, the vehicle further includes a first function switch, the first function switch includes a physical switch and / or a virtual switch, and the virtual switch is arranged in a display interface of the display screen of the multimedia host. The first function switch is used to control the power-on or power-off of one of the detection controller and the signal detector, which is beneficial to saving the energy consumption of the vehicle. For example, when the first function switch is turned on, the detection controller and the signal detector are powered on, and the vehicle can start detecting whether the electronic device is installed on the vehicle body; when the first function switch is turned off, the detection controller and the signal detector are powered off, and the vehicle no longer detects whether the electronic device is installed on the vehicle body.
[0042] In a possible implementation, since the communication device (such as a radio, a T-BOX, or the like) of the vehicle also sends signals when working, to prevent the communication device of the vehicle from interfering with detection of whether the electronic device is installed on the vehicle body, the detection controller sends a shielding signal to the vehicle controller when the first function switch controls the detection controller to be powered on, and the vehicle controller controls the communication device of the vehicle to be in sleep mode after receiving the shielding signal, thereby improving the accuracy of whether the electronic device is installed on the vehicle body.
[0043] For example, the first function switch is a physical switch, one end of the physical switch is grounded, and the other end is connected to a signal input interface of the detection controller. After the detection controller is closed, the signal input interface connected to the detection controller receives a low-level signal, the detection controller sends a shielding signal (for example, a high-level signal) to the vehicle controller, the signal input interface connected to the detection controller receives a high-level signal, and the vehicle controller controls the communication device of the vehicle to be in sleep mode, so that the communication device of the vehicle no longer sends signals.
[0044] In a possible implementation, the signal detector Gi is arranged on the vehicle body through a slide rail, and the signal detector Gi is movable along the slide rail. Figure 4 As shown in Figure 4 FIG. 10 shows an installation diagram of the signal detector, 110 represents a slide rail, and 120 represents a sliding block. The signal detector Gi is fixed on the sliding block, and the sliding block moves along the slide rail, thereby driving the signal detector Gi to move along the slide rail. The sliding block is provided with a limiting threaded hole, and a limiting bolt passes through the limiting threaded hole and is screwed with the limiting threaded hole, so as to limit the movement of the sliding block and start the limiting action. Generally, the signal detector Gi is hidden on the vehicle body. When the vehicle body needs to be repaired or new components need to be added, the signal detector Gi blocks the corresponding position, and the signal detector Gi can be moved along the guide rail to facilitate the repair of the vehicle body or the addition of new components.
[0045] In a possible implementation, as shown in Figure 4 The slide rail is provided with a numerical scale. To avoid a large difference between the actual position coordinates of the signal detector Gi and the first position coordinates stored by the detection controller after the signal detector Gi moves along the rail, the numerical scale is arranged on the slide rail. When the signal detector Gi is moved, the user can refer to the numerical scale on the slide rail to select the movement amount of the signal detector Gi, so as to minimize the difference between the actual position coordinates of the signal detector Gi and the first position coordinates stored by the detection controller.
[0046] In a possible implementation, after the signal detector Gi moves along the guide rail, the actual position coordinates of the signal detector Gi no longer remain consistent with the first position coordinates stored by the detection controller. In order to ensure the consistency between the actual position coordinates of the signal detector Gi and the first position coordinates stored by the detection controller, the display screen of the multimedia host is configured with a setting interface for modifying the first position coordinates stored by the detection controller. The first position coordinates stored by the detection controller are displayed in the setting interface. After a user moves the signal detector Gi according to the scale on the track, the movement amount of the signal detector Gi can be obtained, and the movement amount is input to the setting interface. The multimedia host modifies the first position coordinates stored by the detection controller according to the movement amount input by the user, as shown in Figure 5 Figure 5 A schematic diagram of the setting interface of the position coordinates is shown. If the movement is horizontal, "+" represents the direction to the right of the horizontal scale "0", and "-" represents the direction to the left of the horizontal scale "0". If the movement is vertical, "+" represents the direction above the vertical scale "0", and "-" represents the direction below the vertical scale "0". Figure 5 As shown in the middle of FIG. 12, the user horizontally moves the signal detector n to the right of the scale "0" by 3 scales, the horizontal movement amount is "+3", the first position coordinates Pn of the signal detector n stored by the detection controller are (0, 0, 5), the horizontal movement amount is "+3", the vertical movement amount is "0", and the modified first position coordinates Pn of the signal detector n are (0, 0, 8).
[0047] After obtaining the modified first position coordinates, the multimedia host sends the modified first position coordinates to the detection controller. The detection controller replaces the original first position coordinates based on the modified first position coordinates, thereby ensuring the accuracy of subsequent electronic device positioning.
[0048] In a possible implementation, the vehicle 100 further includes a signal shield and a second function switch, and the second function switch is used to control the power-on or power-off of the signal shield. After a user knows that his vehicle is installed with a monitoring and listening device, the second function switch can be triggered to start the monitoring and listening device. After the signal shield is started, strong electromagnetic interference or radio frequency interference is generated, thereby preventing or disturbing the radio signal transmission in a specific frequency range, so as to prevent the monitoring and listening device from receiving clear signals, and timely block the user's privacy, the vehicle's location, and the like from being remotely obtained by illegal persons through the monitoring and listening device.
[0049] The above merely describes preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the inventive concept of the present application, and by using the content of the present application specification and drawings, are included in the patent protection scope of the present application.
