Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, parking range finding informing device of the present utility model, comprise ultrasonic transmit circuit 1, ultrasound wave receiving circuit 2, phase-locked loop control circuit 3 and wireless transmitter module circuit 4, described ultrasonic transmit circuit 1 and ultrasound wave receiving circuit 2 bidirectional data communications, the output signal of described ultrasound wave receiving circuit 2 is transferred to phase-locked loop control circuit 3, the output signal of described phase-locked loop control circuit 3 is transported to wireless transmitter module circuit 4, and the output signal of described wireless transmitter module circuit 4 is sent to wireless receiving module circuit 5.
Described ultrasonic transmit circuit 1 is made of the transistor VT1 of ultrasonic transmitter B2 and connection thereof, and described ultrasound wave receiving circuit 2 is made of the amplifier IC2 that ultrasonic receiver B1 and output terminal thereof connect.During reversing automobile, when being blocked by the front automobile barrier, the ultrasonic signal of launching reflects amplifier IC2 is coupled in reception by capacitor C 12 pin, after the inner amplification of amplifier IC2, by the output of 6 pin, be coupled to the 3rd pin of LM567 phaselocked loop integration module IC1 again through capacitor C 5.Wherein the signal of 3 pairs of external inputs of phase-locked loop control circuit of being made up of LM567 phaselocked loop integration module IC1 and peripheral cell compares with the oscillation signal frequency of itself, when the signal of the 3rd pin of LM567 phaselocked loop integration module IC1 input greater than 20mV, when inner oscillation frequency is identical with the outside frequency of sending here, 8 pin (logical end) of LM567 phaselocked loop integration module IC1 are exported level from high to low.The oscillator signal that phaselocked loop produces is promoted ultrasonic transmitter B2 and is sent ultrasonic signal by the 6th pin output of LM567 phaselocked loop integration module IC1 after transistor VT1 amplifies.The ultrasonic signal that sends as ultrasonic transmitter B2, because being reflected, barrier receives through ultrasonic receiver B1, amplifier IC2 sends into phase-locked loop circuit after amplifying, through above-mentioned internal circuit relatively after, the 8th pin output low level of LM567 phaselocked loop integration module IC1, triode VT2 saturation conduction, be triggered to the 2nd pin of FDD-5 transmitter module IC4, and deliver to the 3rd pin of FDD-5 transmitter module IC4, be modulation signal input end CP, high-frequency signal to emission is modulated, and the antenna that FDD-5 transmitter module IC4 output terminal connects is namely externally launched modulated frequency electromagnetic waves.
As shown in Figure 3, described wireless receiving module circuit 5 adopts JDD-5 receiver module IC3, the 4th pin audio signal output end CPA of JDD-5 receiver module IC3 directly drives common electrical dynamic formula loudspeaker Y and sends chimes of doom, its the 2nd pin data output end output high level makes LED 1 get electroluminescence simultaneously, expression receives the reminding alarm signal of extension set, remind human pilot to note driving, avoid the generation of accident.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
