Detailed description of the invention
Embodiment 1: vehicle-mounted radio, is the important component part of vehicle-mounted information and entertainment system, the mark of most automobiles
Join, in driving way, provide voice entertainment information for driver.Vehicle-mounted radio is arranged on the fixed mount of middle control operating board, due to
The metal shell of automobile has shielding action to the radio signal in broadcasting station, and the outer antenna that draws of vehicle-mounted radio receives broadcast electricity
The broadcast singal of platform, when vehicle sails the building with blocking property into, such as when underground parking or tunnel, vehicle-mounted radio
Machine cannot continue to the broadcast singal in broadcasting station, commences play out noise, and the attention of dispersion driver, to traffic safety
Impact.
To this end, present embodiments provide a kind of vehicle-mounted radio to control equipment, the hardware unit related to is mainly by following several
Part composition: vehicle-mounted radio, speaker, vehicle data communication gate, vehicle-mounted radio is backed with multi-channel loudspeaker wiring
Terminal, power supply terminal, antenna terminal etc., vehicle data communication gate is internal containing GPS locating module and speaker controller, car
Data communication gateway is hidden and is arranged in car, and speaker controller is connect by the speaker at the wire harness connection vehicle-mounted radio back side
Mouth and speaker.Being received GPS information by vehicle data communication gate, the signal to noise ratio in detection GPS information, when GPS signal to noise ratio
During less than threshold value set in advance, vehicle data communication gate passes through speaker controller mute speaker, when GPS signal to noise ratio
During higher than threshold value set in advance, vehicle data communication gate opens speaker by speaker controller.
When vehicle sails underground parking into, or during tunnel, inject the light in driver's eye and can change suddenly, meanwhile
Radio does not receives the signal from broadcasting station, commences play out noise, and generally driver is in order to reduce radio
Noise, need rapidly regulation radio volume or close radio, when sailing out of underground parking or tunnel, driver is again
Secondary increase radio volume or turn on radio, such operation certainly will increase that driving risk, particularly vehicle condition are unfamiliar drives
The person of sailing, it is in particular possible to occur can not find volume adjustment knob and in a rush situation.
The vehicle of the radio control system described in installation, when vehicle sails underground parking and tunnel into, owing to GPS believes
Ratio of making an uproar passes through speaker controller mute speaker less than threshold value, vehicle data communication gate, plays and eliminates radio noise
Effect, when vehicle sails out of underground parking or tunnel, vehicle data communication gate is opened by speaker controller and is raised one's voice
Device, radio continues to play the broadcasted content of original channel.Whole process is automatically performed, it is not necessary to driver's manual intervention, speaker
Close, thoroughly eliminate radio noise, reduce driver and operate wireless number of times under steam, reduce driving risk and thing
Therefore probability of happening.
GPS information is constantly sent to vehicle data communication gate, GPS information by data-interface by GPS locating module
In comprise the signal to noise ratio of GPS receiver signal, belong to digital signal, when vehicle travels on open highway, often GPS signal to noise ratio
Higher, the GPS information of multi-satellite can be received simultaneously, but when vehicle sails underground parking and tunnel into, due to gps signal
Being high frequency radio wave, can decay rapidly in underground parking and tunnel, the signal to noise ratio of GPS module declines rapidly, and phenomenon is bright
Aobvious, vehicle data communication gate is easy to judge that vehicle has sailed in the building blocked according to GPS signal to noise ratio.
Embodiment 2: a kind of vehicle-mounted radio controls equipment, including vehicle-mounted radio, speaker, vehicle data communication network
