Description

Smart Cradle with Built-in RDS and TMC

The present invention relates to a vehicle cradle of a portable terminal, and more particularly to a vehicle cradle having a radio data system (RDS) and a traffic message channel (TMC) receiver.

In general, in order to get information from the outside while traveling in a car, bus, etc., or to free the radio, many people prefer to listen to radio broadcasts. However, this information is a unilateral information. There was a limit to the acquisition of information by being impossible and relying solely on sound. Due to these problems, efforts have been continuously made to provide various additional information using existing radio broadcasting frequencies, and as a result, listeners can be provided with more various information by adding RDS signals to existing FM frequencies.

RDS service transmits additional digital information such as real-time traffic information, geographic information, news, weather, and stock information to the existing FM 87.5 ~ 108.OMHz frequency band broadcasting radio, and listeners can listen to existing radio through RDS receiver. At the same time, it means an information delivery service that can receive the above information in the form of text.

The TMC service is one of several additional services provided by the RDS service. The TMC service collects real-time traffic information from the FM frequency network in conjunction with a vehicle navigation device and provides it to the route searcher of the electronic map mounted in the navigation. It is a service that provides specialized traffic information such as searching for the optimal driving route by referring to the information provided and displaying an accident point or traffic congestion section on the electronic map. Alternatively, RDS-TMC circuit with TMC function added to RDS can be used, or TMC circuit can be configured separately from RDS to link with navigation device. In this case, only the TMC function can be used among several service functions of RDS.

This RDS service provides a variety of additional information through the public wireless network, and plays an important role in providing information to users who need real-time information with a wide range of service areas, low operating prices, and free or low-cost information service fees. do.

The RDS service is equipped with an RDS data analyzer in an FM broadcast receiver including a liquid crystal display (LCD) or an LED display to convert the received broadcast wave into original data, and converts the analyzed data into the LCD or LCD. The service can be used by expressing on the LED display.

Although the RDS and TMC services have various additional functions and advantages, some problems and improvement problems are emerging.

 Conventional RDS service terminals are usually provided in the form of vehicle audio and can use existing radio broadcasting and RDS service through the vehicle audio, and in some products, car audio video navigation equipment (AVN) Navigation) also provides RDS and TMC services together. In addition, the vehicle acoustic video navigation devices that do not provide RDS services may be separately installed by using an external TMC receiver, but in this case, the existing devices may be installed only if a communication terminal for TMC connection is already provided.

Recently, due to the development of portable terminal devices, devices such as mobile phone devices, PDA (Personal digital assistants), PMP (Portable multimedia player), PND (Personal navigation device), UMPC (Ultra Mobile Personal Computer) support navigation functions Users carry it around and use it as a multimedia player or informatization device, and mount it on a vehicle cradle that is safely supported and supplied to the vehicle for reasons such as charging, preventing damage, convenience of operation, and safety problems when boarding the vehicle. have. These portable terminal devices have a basic liquid crystal display device, a function key, a memory, and a CPU as basic components. The portable terminal device displays the RDS or TMC service information on the screen of the portable terminal device, and displays the function key of the portable terminal device. If you can operate RDS or TMC service and use TMC information when using navigation, you can use the same function without purchasing expensive RDS-TMC-supported car sound image navigation device.

However, in order to use RDS and TMC service in portable terminal equipment, separate external RDS-TMC receiver should be installed, FM receiving antenna should be installed, power should be supplied, and between RDS and TMC receiver and portable terminal equipment. In addition to interconnecting the signal lines for communication, the portable terminal device can only be carried when the vehicle is disconnected from the vehicle.

In addition, it is difficult to utilize when the communication signal terminal or communication standard is different between the RDS-TMC receiver and the portable terminal device, and the FM antenna line, the receiver, and the communication signal line are complicated around the vehicle cradle for mounting the portable terminal device. There is a problem that can be deployed to interfere with the safe driving, the radio wave interference with the GPS, mobile phones, radio mounted on the vehicle, etc. can occur.
