Referring to fig. 1, the utility model provides a fuse multi-antenna's mobile unit, including ETC module 110, V2X module 120, host system 100 and display module 160.

The ETC module 110 is used for realizing Electronic Toll Collection (ETC) with an ETC antenna 170 integrated on an in-vehicle device and close to a front windshield.

In the present embodiment, the ETC module 110 includes a read/write card unit, an encryption unit, and a mechanical tamper unit (none of the above unit figures are shown), wherein the read/write card unit and the encryption unit are used to complete a transaction fee deduction of the ETC through cooperation. For example, the ETC antenna 170 in this embodiment is a 5.8Ghz antenna, and is used for performing radio frequency communication with a road side unit having an ETC function. The read-write card unit adopts a 13.56MHz module and is used for realizing data writing and reading functions. The encryption unit adopts an ESAM Module (Embedded Secure Access Module) with a Chinese name of an Embedded safety control Module, and is used for mutual authentication with the road side unit, storing system and vehicle information and ensuring safe and reliable transaction. The ETC antenna 170, the read-write card unit and the encryption unit cooperate to complete the ETC transaction fee deduction, which is the prior art and is not described herein again.

The mechanical anti-dismantling unit is used for sending a dismantling signal when the vehicle-mounted unit is dismantled, so that the ETC module 110 stops transaction fee deduction, namely at least one of the read-write card unit and the encryption unit is forbidden, and property loss of a user is avoided. The mechanical tamper unit ensures that the security of the funds on the user card is not compromised even if the on-board unit is removed. The mechanical anti-dismantling unit can specifically adopt an anti-dismantling switch, such as a non-self-locking switch, the non-self-locking switch is positioned in an electrified loop, the switch is bounced open after the vehicle-mounted unit is dismantled, and the loop is disconnected, so that an electric signal is generated to the ETC module 110, the ETC module 110 stops transaction function, starts alarm prompt and the like.

In an alternative embodiment, the ETC module 110 further includes an alarm unit (not shown) for emitting an acoustic, optical or electrical signal to alarm when the ETC module 110 is abnormal, and the alarm unit may be a buzzer or an indicator lamp.

The V2X module 120 is used to implement V2X road cooperative communication with the V2X antenna 220 integrated in the shark fin structure 200 on the roof, in this embodiment, the V2X module 120 is connected to the V2X antenna 220 through a radio frequency cable, so as to establish a V2X data channel, and implement V2X bidirectional communication with surrounding vehicles or roadside devices and the like. In other embodiments, the V2X antenna 220 may be mounted elsewhere on the vehicle body, or within other antenna-integrated structures.

The main control module 100 is electrically connected to the ETC module 110 and the V2X module 120, respectively, for example, the ETC module is connected to the main control module 100 through an SPI/UART/I2C interface. The main control module 100 is configured to generate the ETC transaction information according to the ETC electronic toll collection implemented by the ETC module 110, and generate the V2X prompt information according to the V2X vehicle-road cooperative communication implemented by the V2X module 120.

The display module 160 is connected to the main control module 100 by signals, for example, the display module 160 is connected to the main control module 100 through an HDMI/LCD interface. The display module 160 is configured to receive and display the ETC transaction information generated by the main control module 100, and/or the V2X prompt message, and a liquid crystal display or a touch screen may be used as the display module 160. For example, when the vehicle travels on a toll highway and passes through a toll portal frame and a highway entrance, the vehicle-mounted device finishes fee deduction, and the main control module 100 outputs the generated fee deduction information to the display screen for displaying (as shown in fig. 2). The vehicle-mounted equipment can also store time, fee deduction information and the position of a vehicle when fee deduction is carried out, so that later-stage query is realized, and the vehicle-mounted equipment is more friendly than ETC human-computer interaction in the existing market and more convenient and clear in query.

Similarly, when the vehicle enters or exits the parking lot supporting ETC parking, the vehicle-mounted device completes the parking fee deduction, and the main control module 100 outputs the generated fee deduction information to the display screen for displaying (as shown in fig. 3). And the vehicle-mounted equipment stores time, fee deduction information and the position of the vehicle during fee deduction for later-stage query.

For another example, the vehicle-mounted device broadcasts the position and speed information of the vehicle in real time through the V2X module 120 and the V2X antenna 220, when the vehicle passes through an intersection without traffic lights, the collision expectation generated at the intersection with other networked vehicles (the vehicle also having the V2X module 120) can be obtained through the existing software algorithm, and the main control module 100 can generate a corresponding collision early warning picture and output the same to the display screen for display (as shown in fig. 4).

The integrated ETC technology and the V2X technology of the vehicle-mounted equipment are more advanced and friendly than the traditional ETC terminal in the aspects of functions and display modes, and promote the existing V2X terminal in the aspects of cost and use convenience.

It should be noted that in some examples, the vehicle-mounted device may be provided with only one of the LTE module 140 and the WIFI module 150 to connect to the internet.

By connecting to the Internet, the vehicle-mounted equipment has more expansion functions. For example, when a vehicle approaches a traffic light with a networking function, the traffic light with the networking function broadcasts the state of the traffic light and the position information of the traffic light through an LTE-V network. After the vehicle-mounted device receives the traffic light broadcast message, the main control module 100 can calculate the distance to the traffic light and the traffic light state suitable for the vehicle according to the traffic light position and the self position. When the distance between the vehicle and the traffic light is less than 100 meters, the traffic light status and distance are displayed on the display module 160.

In some embodiments, the vehicle-mounted device may further include an audio module, and in a scene where the vehicle is close to a traffic light with a network connection function, the vehicle-mounted device may calculate a risk that the vehicle runs the red light by a vehicle speed, a distance between the traffic light, and a remaining display seconds of the traffic light. When the distance between the vehicle and the traffic light is less than 30 meters and the risk of running the red light is obvious, the main control module 100 injects the red light alarm information to the display module 160 for displaying, and the main control module 100 controls the audio module to send out an early warning sound prompt.

Compared with the prior art, the vehicle-mounted equipment has the advantages that the display mode of the traffic light cooperation of the vehicle with the internet function is displayed in the automobile central control, the related APP in the automobile central control needs to be opened, and the driver needs to look down to see information.
