DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] Figure 1 This is a schematic diagram of the structure of a mandatory driving safety communication system provided by this embodiment. Figure 1 The system includes a signal jammer 101, a terminal bracket 102, a micro base station 103 and a signal shielding cover 104, wherein the signal jammer 101, the terminal bracket 102, and the micro base station 103 are all arranged in the main driving room 301 of the vehicle 300, and the signal shielding cover 104 is arranged on the outside of the terminal bracket 102 and the micro base station 103.

[0040] In this embodiment, the terminal bracket 102 is used to support and fix the mobile terminal, and the signal shielding cover 104 covers the terminal bracket 102 and the mobile terminal together. The signal jammer 101, the terminal bracket 102 and the signal shielding cover 104 can be fixed on the surface of the main driving room 301, such as the A-pillar, the car center console, etc., by means of adhesion, clamping, etc.

[0041] It should be noted that at least two of the terminal bracket 102, the micro base station 103 and the signal shielding cover 104 can be arranged as an integrated structure, that is, the micro base station 103 can be integrated into the terminal bracket 102, the micro base station 103 can be fixed on the inner surface of the signal shielding cover 104, the terminal bracket 102 and the signal shielding cover 104 can be integrated together, and the terminal bracket 102, the micro base station 103 and the signal shielding cover 104 can be arranged as an integrated structure.

[0042] Reference Figure 2 The signal jammer 101 is provided with an interference signal generating module 1012, which generates and transmits interference signals to the outside. By adjusting the transmission power, the interference range can be set to the range of the main cab 301, that is, the signal jammer 101 only interferes with the wireless signal transmission and reception between the mobile terminal in the main cab 301 and the external base station, and does not affect the wireless signal transmission and reception between the mobile terminal in the vehicle area outside the main cab 301 (such as the co-driver's cab 302, the rear passenger area 303) and the external base station. Among them, the external base station is an interface device invested and built by mobile communication operators such as China Mobile, China Unicom, and China Telecom to enable mobile terminals to access the Internet.

[0043] Optionally, the interference signal generating module 1012 is composed of at least two groups of Wien bridge oscillators and a single-chip microcomputer, each group of Wien bridge oscillators corresponds to a different oscillation frequency, and the single-chip microcomputer controls the selection of any group of Wien bridge oscillators.

[0044] Reference Figure 3 The micro base station 103 includes a base station module 1031, a built-in antenna 1032 connected to the base station module 1031, and a first power supply module 1033; and the signal shielding cover 104 is made of shielding material and can shield interference signals. Therefore, when the mobile terminal is placed on the terminal bracket 102, the signal shielding cover 104 can shield the interference signal emitted by the signal jammer 101, and the mobile terminal can receive the wireless signal emitted by the built-in antenna 1032, and the built-in antenna 1032 can also receive the wireless signal sent by the mobile terminal.

[0045] The base station module 1031 includes a base station chip and a transceiver, and the transceiver is respectively connected to the base station chip and the built-in antenna 1032. The model of the base station chip can be XC7VX980T; the built-in antenna 1032 can be an LDS laser antenna, an SMT patch antenna, an onboard PCB antenna, an FPC antenna, etc., which is not specifically limited in this embodiment.

[0046] However, since the signal shielding cover 104 not only shields the interference signal emitted by the signal jammer 101, but also shields other normal wireless communication signals, the micro base station 103 placed in the signal shielding cover 104 cannot communicate with the external base station. Therefore, the call and network functions of the mobile terminal cannot be realized.

[0047] To solve this problem, the present embodiment designs the micro base station 103 as a dual-path antenna. On the basis of the original internal antenna 1032, an external antenna 1034 is added in the vehicle area outside the main driving room 301. Figure 1 As shown, the external antenna 1034 is arranged on the outside of the roof corresponding to the co-pilot cabin 302, and as shown in Figure 3 As shown, the external antenna 1034 is connected to the transceiver in the base station module 1031 to realize the wireless signal transmission and reception between the micro base station 103 and the external base station, thereby realizing the network and call functions of the mobile terminal.

[0048] Specifically, the external antenna 1034 may be an external rod antenna, a suction cup antenna, or other types of antennas, which is not specifically limited in this embodiment.

[0049] In this embodiment, the mobile terminal may be an electronic device with a network function and / or a call function, such as a mobile phone or a tablet computer, which is not specifically limited in this embodiment.

[0050] Through the above embodiment, as long as the driver places the mobile terminal in the signal shielding cover 104, the mobile terminal can perform normal functions such as calls, text messaging, and Internet navigation; once the driver takes the mobile terminal out of the signal shielding cover 104, the mobile terminal is immediately in the signal interference range of the signal jammer 101, unable to communicate with the external base station, and unable to perform normal calls, text messaging, and Internet navigation. The driver is guided to use the mobile phone safely during driving, get rid of the bad habit of looking down at the mobile phone and other electronic products, and reduce the probability of traffic accidents.

[0051] In this embodiment, the start and stop of the signal jammer 101 can be controlled according to the driving speed of the car. Specifically, it can be directly controlled by the car speed control system, or by adding a speed detection function to the signal jammer 101.

[0052] The start and stop control of the signal jammer 101 will be specifically described below from these two perspectives.

[0053] First way:

[0054] Reference Figure 4, connect the interference signal generating module 1012 of the signal jammer 101 to the ECU201 of the vehicle speed control system 200; when the vehicle speed sensor 202 of the vehicle speed control system 200 detects that the current vehicle speed is greater than zero, the ECU201 generates a first start control signal and sends it to the signal jammer 101, controls the signal jammer 101 to start, and emits interference signals outward; when the vehicle speed sensor 202 of the vehicle speed control system 200 detects that the current vehicle speed is equal to zero, the ECU201 generates a first shutdown control signal and sends it to the signal jammer 101, controls the signal jammer 101 to shut down, and stops emitting interference signals outward.

[0055] The vehicle speed control system 200 is a built-in system of the vehicle 300. In this way, the external interface of the vehicle speed control system 200 is connected to the control interface of the signal jammer 101, so that the automatic start and stop of the signal jammer 101 can be controlled by the existing system.

[0056] Second way:

[0057] Reference Figure 2 The system also includes a speed measuring device 105 located outside the interference range of the signal jammer 101, which is used to control the start and stop of the signal jammer 101 according to the current vehicle speed.

[0058] Optionally, the speed measuring device 105 includes a GNSS antenna 1051, a GNSS receiver 1052, a control module 1053, a first transmission interface module 1054, and a second power supply module 1055. The GNSS receiver 1052 calculates the current vehicle speed according to the satellite signals of the two points received by the GNSS antenna 1051, and sends the current vehicle speed to the control module 1053; when the current vehicle speed is greater than zero, the control module 1053 generates a second start control signal and sends the second start control signal to the signal jammer 101 through the first transmission interface module 1054; when the current vehicle speed is equal to zero, the control module 1053 generates a second shutdown control signal and sends the second shutdown control signal to the signal jammer 101 through the first transmission interface module 1054; the second power supply module 1055 provides power to the GNSS receiver 1052, the control module 1053, and the first transmission interface module 1054.

[0059] Preferably, the GNSS receiver 1052 may use a GPS chip or a Beidou chip, and correspondingly, the GNSS antenna 1051 may use a GPS antenna or a Beidou antenna. The control module 1053 may use a PIC 8-bit microcontroller 16F877 from Microchip.

[0060] Reference Figure 2The signal jammer 101 includes a second transmission interface module 1011, an interference signal generating module 1012 and a third power supply module 1013. The second transmission interface module 1011 receives the second start control signal sent by the first transmission interface module 1054 and transmits it to the interference signal generating module 1012. The interference signal generating module 1012 generates and emits an interference signal in response to the second start control signal; the second transmission interface module 1011 receives the second shutdown control signal sent by the first transmission interface module 1054 and transmits it to the interference signal generating module 1012. The interference signal generating module 1012 stops emitting interference signals in response to the second shutdown control signal; the third power supply module 1013 provides power to the second transmission interface module 1011 and the interference signal generating module 1012.

[0061] It should be noted that in order to prevent the interference signal emitted by the signal jammer 101 from interfering with the wireless transmission between the signal jammer 101 and the speed measuring device 105, wired signal transmission is adopted between the signal jammer 101 and the speed measuring device 105, and in order to prevent the interference signal emitted by the signal jammer 101 from affecting the GNSS antenna 1051 of the speed measuring device 105 from receiving satellite signals, the speed measuring device 105 needs to be set in a vehicle area outside the interference range of the signal jammer 101.

[0062] This method does not require any improvement to the vehicle 300 itself and is easy to promote.

[0063] The start and stop of the signal jammer 101 are controlled by the above two methods. When the vehicle 300 is turned off or the speed is zero after starting, the signal jammer 101 does not work. During starting driving, the signal jammer 101 transmits a jamming signal.

[0064] In order to minimize the possibility of the signal jammer 101 affecting the wireless signal reception and transmission in vehicle areas other than the main cab 301, the antenna of the signal jammer 101 can be set as a directional antenna, and the signal jammer 101 and the directional antenna can be set on the roof of the vehicle in the main cab 301. The directional antenna can transmit interference signals downward. The directional antenna emits particularly strong electromagnetic waves in the vertical downward direction, while the electromagnetic waves emitted in other directions are zero or extremely small.

[0065] Reference Figure 2 and Figure 4 The signal jammer 101 may further include a frequency conversion module 1014 connected to the interference signal generating module 1012, for adjusting the signal frequency generated by the interference signal generating module 1012. Specifically, a Wennbridge oscillator may be used to accurately control the transmission frequency of the interference signal, thereby enhancing the accuracy of controlling the frequency band of the interference signal.

[0066] Since the transmission power of the signal jammer 101 can be set so that it does not interfere with the Bluetooth signal, the mobile terminal in this system can still be connected to the car central control system by Bluetooth. Even if the mobile terminal is placed in the signal shielding cover 104, the car central control panel can display incoming calls, play music, etc., and can answer incoming calls.

[0067] In addition, when the mobile terminal is placed on the terminal bracket 102, the charging operation of the mobile terminal can also be realized. Figure 5 The terminal bracket 102 includes a first interface 1021, an interface conversion module 1022 and a second interface 1023, and the first interface 1021 and the second interface 1023 are both connected to the interface conversion module 1022; the first interface 1021 is used to connect to the charging interface of the mobile terminal; the second interface 1023 is used to connect to the charging interface of the vehicle 300.

[0068] Among them, the first interface 1021 may include but is not limited to at least one of a lighting interface, a Type-C interface and a Micro-USB interface, and can be applicable to mobile phones and tablets of various brands and models.

[0069] In order to facilitate users to place and take the mobile terminal, the signal shielding cover 104 includes a base and a cover body buckled with the base. In order to facilitate users to observe the screen of the mobile terminal, a transparent area is set on the signal shielding cover 104, and the transparent area is made of transparent shielding material.

[0070] Preferably, the signal jammer 101 and the micro base station 103 can be self-powered, such as solar power generation.

[0071] Specifically, the first power module 1033 includes a micro solar panel and a rechargeable battery connected to the micro solar panel. Since the signal shielding cover 104 is made of shielding material and is generally opaque, the micro solar panel needs to be arranged on a side surface of the terminal bracket 102 close to the signal shielding cover 104 and facing the transparent area to realize the solar charging function.

[0072] Similarly, the second power module 1055 and the third power module 1013 may also include a micro solar panel and a rechargeable battery connected to the micro solar panel, which will not be described in detail here.

[0073] Of course, the signal jammer 101, the micro base station 103, and the speed measuring device 105 can also be powered by a vehicle-mounted 230VAC power supply, and the first power module 1033, the second power module 1055, and the third power module 1013 are corresponding power adapters.

[0074] In addition, it should be understood that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.

[0075] The terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0076] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the aforementioned application concept. For example, the above features are replaced with (but not limited to) technical features with similar functions applied in the present application.
