A system for interconnection and intercommunication between mobile communication equipment and vehicle-mounted radio stations

Abstract

The invention discloses a system for interconnection and intercommunication between a mobile communication device and a vehicle-mounted radio station, which includes a vehicle-mounted radio station and a mobile communication device. The wireless transceiver circuit and the mobile communication equipment realize interconnection and intercommunication, realize the two-way communication of data and voice between the vehicle radio and the mobile communication equipment, and realize the integration of the mobile communication equipment to the vehicle radio wireless remote operation control, wireless reading and writing frequency and air upgrade. After adopting the technical scheme of the present invention, the vehicle-mounted radio does not need a display unit and a hand microphone, but only needs a host unit and an additional wireless transceiver circuit, and cooperates with a mobile communication device to form a new type of large-screen vehicle-mounted walkie-talkie, subverting people's perception of vehicle-mounted radios. The traditional impression of radio.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted walkie-talkies, in particular to a system for interconnection and intercommunication between mobile communication equipment and vehicle-mounted radio stations. Background technique [0002] The traditional car radio generally includes a host and a hand microphone that are set separately. The host is equipped with a host control unit and a display operation control unit. The hand microphone is equipped with a hand microphone unit. The hand microphone communicates with the host control unit through the display operation control unit. connect. The traditional car radio display unit and hand microphone unit are indispensable components, which virtually increases the cost of the car radio. [0003] In the existing car radio, the main unit is generally installed in the front window of the car or in the storage compartment of the car, and the hand microphone is placed where the driver can easily...

AI Technical Summary

Problems solved by technology

[0005] (1) The user of the car radio station can only be within the range of human touch around the installation position of the radio station or the stretching length of the hand microphone line (between 0.5 and 1.5 meters), otherwise it will not be possible to operate and control the car radio station and communication intercom

[0006] (2) When the car radio is used for programming and writing frequency, it is necessary to use a dedicated computer frequency writing cable to connect to the computer for operation. It is necessary to purchase a special computer frequency writing cable to increase the cost. The car radio needs to be removed from the car. One-time installation, very inconvenient to operate

[0007] (3) When there are bugs in the microprocessor software of the car radio or new functions need to be added, software upgrades are required. The previous upgrade method needs to use a software writer to connect the computer and the car radio to upgrade the software. Once this upgrade method Encountering software problems in batches, it is necessary to recall and upgrade the whole batch, which is likely to cause huge losses; when the car radio has new functions, the company wants to provide an upgrade experience for free, increase user experience and praise, the existing car radio cannot be realized

[0008] (4) Limited by the segmented display screen of the car radio, the display screen size is small, the interface is fixed, the length of the text information is limited, the icon is simple, and the readability is poor; recently, dot matrix and color screen displays have been developed, but there are still low resolution and color. Insufficient and other problems, while increasing costs

Regardless of the display method, when the customer customizes and modifies the display content, the segment display screen needs to be re-opened; the dot matrix and color screen displays need to modify the software, increase software version management and differentiation, increase production difficulty and material procurement costs

[0009] (5) Although there are Bluetooth wireless mobile microphones or other wireless mobile microphones on the market that can be used with car radios, they can only realize voice communication, without display and operation control functions, without wireless computer programming read and write functions, and without wireless air Upgrade software function, which increases the purchase cost and has a single function

[0010] With the advent of the Internet of Things era, people's living standards are also improving, and traditional car radios can no longer meet people's needs
