The detector unit 260 is electrically connected to the plurality of sensing units 23A, and an amplifier unit 250 can be placed between them to increase the signal strength. The amplifier unit 22A, 25A can select a TIL08 component or other amplifier component, and the detector unit 26 can select a 4148 component or other diode component. The wireless transmitting system 200 is configured to perform data processing and transmit a radio frequency signal. The radio frequency signal operates in the frequency range of 1 〇〇 MHz to 800 MHz, and the optimum operating frequency is 433.92 MHz. The RF signal sets an operating frequency that will carry both the authentication material, the sensing material, and the -lin data. The authentication data is used to identify the '5 association' between the wireless transmitting unit 27() and the wireless receiving unit (10) to prevent interference from other communication products. The sensing data is generated by any one of the plurality of sensing units 7L 230 receiving the second signal by transmitting the first signal and the refractive index. The distance data is obtained by the above formula (]). ° Please refer to the top view of the reversing radar device without retransmission. The plurality of sensing units 23() and the wireless transmitting system may be referred to as a wireless transmitting device with a distance. For example, the first microprocessor unit 210 transmits a -4 〇 KHz step signal, and then touches the sensing unit 235 through the amplifier unit. Then, the sensing unit 235 emits a fourth signal of 4 kHz, and the encounter-object 243 reflects the signal, and the sensing unit 235 receives the second signal and within the waiting time range, please refer to FIG. The second signal is amplified by the H unit 25G, and then the signal is sampled by the detecting unit (10). The signal is then sent to the first microprocessor unit 21 for analysis and comparison with the first signal. Therefore, the sensing data and the distance data are obtained, and the wireless transmitting unit 270 then up-converts the signal to 433.92 MHz for transmission. When the sensing unit 235 does not detect any reflected signals, the first microprocessor unit 210 does not perform signal analysis. Different sensing units 231242 will have different sensing materials. The radio frequency signal transmitted by the wireless transmitting system 2GG is received by the wireless receiving system 101, which performs subsequent data operations and processing. The wireless receiving unit 110 of the wireless receiving system M406550 receives the RF signal and down-converts from 433.92 MHz to 40 ,, and then transmits the signal to the second microprocessor unit 120 for arithmetic processing. The second microprocessor unit 12 controls the warning unit 150 and the display unit 13A, and the warning unit 150 generates an alert sound to inform the driver. The distance display unit 143 in the display unit 130 displays a distance value, that is, the distance information provided in the radio frequency signal, please refer to FIG. The sensing data provided in the RF signal will be used for a plurality of warning lights 13M42 in the display unit 130, each of which is represented as an orientation. Therefore, the sensing data generated by the sensing unit 231 corresponds to the warning light 131 in the display unit. Therefore, the sensing data generated by the sensing unit 232 corresponds to the warning light 132 in the display unit. Therefore, the sensing data generated by the sensing unit 233 corresponds to the warning light 133 in the display unit. Therefore, the sensing data generated by the sensing unit 234 corresponds to the warning light 134 in the display unit. Therefore, the sensing data generated by the sensing unit 235 corresponds to the warning light 135 in the display unit. Therefore, the sensing data generated by the sensing unit 236 corresponds to the warning light 136 in the display unit. Therefore, the sensing data generated by the sensing unit 237 corresponds to the warning light 137 in the display unit. Therefore, the sensing data generated by the sensing unit 238 will correspond to the warning light 138 in the display unit. Therefore, the sensing data generated by the sensing unit 239 corresponds to the warning light 139 in the display unit. Therefore, the sensing data generated by the sensing unit 240 corresponds to the warning light 140 in the display unit, so the sensing data generated by the sensing unit 241 corresponds to the warning light 141 in the display unit. Therefore, the sensing of the 9 W06550 sensing 7G 242 will correspond to the display 142 of the display unit. °, please refer to Fig. 5 for a side view of the reverse wheel type reversing radar device of the present embodiment. The wireless receiving system (9) and the display unit 30 are installed in the vehicle, and the wireless transmitting system is mounted on the trailer chassis and coupled to the sensing unit 230.
