Example Embodiment

[0015] See figure 1 , figure 2 As shown, the embodiments of the present invention are described in detail.

[0016] Such as figure 1 As shown, the method of the present invention specifically includes the following steps: Step 10, the antenna outside the vehicle receives wireless signals, and antennas of different frequency bands can be selected to receive wireless signals of different frequency bands; Step 20, the signal received by the antenna is transmitted to the outside of the vehicle The processing is performed in the control circuit module. The control circuit module converts the received wireless signal into a digital signal through a corresponding conversion module, controls the transmission and reception interval and timing of the data stream through a microprocessor, and customizes the data stream format; step 30 , The signal processed by the control circuit module is wirelessly transmitted to the RF receiving module in the car through the RF transmitting module outsi...

Abstract

The invention provides a signal receiving method of a vehicle-mounted antenna, which concretely comprises the following steps of: a step 10: receiving a radio signal by an antenna outside a vehicle; a step 20: conveying the signal received from the antenna into a control circuit module outside the vehicle for processing; a step 30: uniformly transmitting a signal processed by the control circuit module to a RF (Radio Frequency) receiving module in a vehicle through an RF sending module outside the vehicle; and a step 40: receiving the signal sent by the RF sending module by the RF receiving module in the vehicle and transmitting the received signal to an information service terminal. The method can avoid wire connection of external antennas, the signals are stable, multi-channel signals are received according to demands and the signals are made to pass through the vehicle so that the whole vehicle is covered by the information.

Description

【Technical field】 [0001] The invention relates to the field of antennas, in particular to the field of vehicle-mounted antennas. 【Background technique】 [0002] Existing vehicle-mounted communication terminals communicate with the outside world through wired antennas. For example, vehicle-mounted GPS needs to install an antenna outside the vehicle and lead it into the vehicle through wires or feeders. If the antenna is not placed outside the car, but placed directly inside the car, the signal will be relatively poor due to the blockage of the car body, and the signal will not even be received. Moreover, with the development of technology, the wireless frequency band continues to increase, while the existing original vehicle They are all FM / AM frequency bands, and there are very few high-frequency or even ultra-high-frequency antennas. Therefore, it has become a problem that must be solved to have a suitable antenna to meet the needs of current vehicle communication. If you ...
