11. A wireless monitor voice indication parking indicator comprising:
-
a transmitting part comprising a Single-Chip Microcomputer (SCM) processor operatively coupled to a camera, an ultrasonic transmitting circuit, an ultrasonic receiving circuit having a plurality of ultrasonic sensors and ultrasonic sensor matching circuits, a power circuit, a voice indication circuit, a video superimposed circuit, and a wireless transmitting circuit; and a receiving part configured to communicate with the transmitting part, the receiving part comprising a power circuit, a wireless receiving circuit, an audio separation circuit, a control magnification output circuit, an alarm, and a monitor, wherein a built-in control program of the SCM processor of the transmitting part sends out supersonic impulse signals, by channels selection, circularly assigns the supersonic impulse signals to each ultrasonic sensor matching circuit through which supersonic voltages are added on ultrasonic sensors; the ultrasonic sensors send out ultrasonic waves and gain electric signals received by the ultrasonic sensors when the discharged ultrasonic waves meet an obstacle and reflect; the electric signals, through frequency selection and magnification of an operational amplification circuit, send square waves to the SCM processor; the SCM processor circularly scans every channel, and in a circle, the SCM processor disposes received square-wave signals, changes analog signals into digital signals and writes the digital signals into a buffer to calculate and compare, and gets and compares distances between the ultrasonic sensors and the obstacle in the circle to gain a shortest distance; the SCM processor superimposes characters on video through the video superimposed circuit on the basis of distance and orientation, and video signals with superimposed characters are sent to the wireless transmitting circuit to send out signals; the SCM processor sends calculated shortest distance and orientation indications to the voice indication circuit, and the voice indication circuit sends out readable audio signals of distance and orientation and then sends to the wireless transmitting circuit to send out signals; and the wireless receiving circuit of the receiving part receives the video signals with superimposed number and orientation and the audio signals, separates through the audio separation circuit and sends signals to the control magnification output circuit, and sends the audio signals to the alarm and the video to the monitor to display. - View Dependent Claims (12, 15, 16, 17, 18, 19)
