Control switch 2 and testing circuit 1 can be integrated into the weary again relay of identical function.Testing circuit 1 can be the input that lead is sent to signal control switch 2..
The sound equipment tone playing equipment can be (mobile phone) earphone, also can be broadcast receiver, also can be loudspeaker.
Auto alarm lamp in signal when testing circuit is used for detecting the auto alarm lamp can be the automobile coolant temperature alert light, also can be the automobile oil alarm lamp, also can be the automotive brake fluid alarm lamp, also can be engine alarm lamp etc.
In the utility model, the signal that testing circuit is used for detecting can be in above five kinds one or more.
Control switch output control signal has makes automobile audio outage or quiet or volume turn down in three kinds one or more.
The sound equipment tone playing equipment can be one or more in three kinds on (mobile phone) earphone, broadcast receiver, loudspeaker.
The user can adopt one or more in the above combination according to the needs in the actual conditions.
Application examples one:
When testing circuit was used for detecting the signal of air bag, the signal that testing circuit is used for detecting can be the signal of sensor of air bag; The signal that testing circuit is used for detecting can be the voltage or the current signal of the igniter of air bag; The signal that testing circuit is used for detecting can be the blast open mode signal of air bag.The transducer of air bag can be a crash sensor.
When the blast of air bag was opened, the signal that testing circuit detects air bag changed, thereby control switch 2 turns down hoot device 3 outage or quiet or volume according to the output signal of testing circuit 1 output.Help the safety after the accident.
Application examples two:
When testing circuit was used for detecting the signal of tire pressure detector, the signal that testing circuit is used for detecting can be the signal of sensor of tire pressure detector; The signal that testing circuit is used for detecting can be under-voltage, superhigh pressure, the high temperature signal of tire pressure detector; The signal that testing circuit is used for detecting also can be sound, the light cue of tire pressure detector.
When under-voltage, the superhigh pressure of tire pressure detector, high temperature signal, the signal that testing circuit detects tire pressure detector changes, thereby control switch 2 makes hoot device 3 outages or quiet according to the output signal of testing circuit 1 output.Driver's reaction speed is accelerated, reduced danger.
Signal when testing circuit is used for detecting reversing; Signal when testing circuit is used for detecting the rain brush high-speed cruising; Signal when testing circuit is used for detecting the auto alarm lamp; Its principle is identical.
