Detailed Description

The present invention will be described in further detail with reference to fig. 1 to 7.

The utility model provides a visual radar system of loader, it influences traditional backing a car and backing a car radar function integration for one set of system, the detection distance of backing a car that both can be accurate, again can multi-functional feedback video image, reduced the blind area problem of the radar of backing a car probably producing and the potential safety hazard that the image of backing a car probably produced.

The utility model discloses radar system includes camera 1, video line, video extension line 2, display 3, display power cord 4, serial ports line, serial ports extension line 5, controller power cord 6, radar sensor probe 7, radar pencil extension line 8 and radar host 9.

Be connected through video line and video extension line 2 between camera 1 and the display 3, be connected through serial ports line and serial ports extension line 5 between display 3 and the radar host computer 9, be connected through radar pencil and radar pencil extension line 8 between radar host computer 9 and the radar sensor probe 7.

The controller, i.e. the radar host 9, integrates circuit modules such as a power circuit, a CPU processing circuit, an inductor signal transceiving processing circuit, and the like, collects corresponding signals, performs conversion processing, and feeds the signals back to the display 3.

The display 3 integrates the corresponding circuit modules with the functions of buzzing alarm, picture display, voice prompt, reverse distance display, automatic probe detection and the like, and is more reliable than a single buzzing alarm circuit module.

The radar sensor probe 7 is a digital radar, the MCU and other circuit modules are arranged in the probe, the MCU arranged in the probe drives the probe to emit waves, echo signals of the probe core are directly amplified at the probe end, AD acquisition and processing are carried out, and probe data are transmitted in a digital signal mode.

The utility model discloses an implement the principle: when the automobile is in a reverse gear state, the rearview radar system starts to work, the radar sensor probe 7 transmits an ultrasonic signal, once an obstacle appears behind the automobile, the ultrasonic wave is reflected by the obstacle, and the radar sensor probe 7 receives a reflected wave signal; the radar host 9 processes the reflected wave signal to determine the position of the obstacle and the distance to the vehicle body, and finally feeds back information to the driver through the display 3 in the form of sound (buzzer), data (distance display), image (display screen simulation), and the like, as shown in fig. 3.

The working principle of the reversing radar is that the distance to the nearest obstacle is detected by an ultrasonic sensor, the received signal is processed by a controller, namely a radar host 9, to give a feedback signal, and finally a siren is given to warn the driver, as shown in fig. 6.

The control of the siren sound is usually divided into two stages, when the distance of the vehicle reaches a certain distance to start detection, the siren sound starts to sound with a certain high-frequency siren sound, and when the vehicle travels a certain distance closer, the siren sound changes to a continuous siren sound to inform the driver.

The loader backsight radar system's display 3 suggestion is installed inside the driver's cabin, and camera 1 installs in complete machine rear position, and the radar probe is for being in balancing weight rear and side position (the mounted position schematic diagram is shown in fig. 7), and radar host computer 9 position can select in the driver's cabin or the inside both sides position of balancing weight, avoids exposing outside, prevents into water, influences the performance.
