AI Technical Summary

Problems solved by technology

However, this information is displayed in the form of graphics and text on the screen. The disadvantage is that the driver must use his eyes to see the graphics and text on the screen to know that he needs information.
Especially when the car is driving, watching the graphics and text on the screen will be distracting, and there is also a great potential safety hazard

Embodiment Construction

[0016] Its main feature is to install the transmitting radar on the ground so that the radar beam faces the car in the direction of travel beyond the set distance. Of course, due to the different installation positions, the distance covered by the radar beam is different. The voice information set by each transmitting radar All are stored during installation according to the actual location of its installation and the specific conditions of the environment, so the information emitted by the launch radar is accurate. The actual location and environment where the transmitting radar is installed is different, and the stored voice information is also different.

[0017] An on-vehicle radar receiver mounted on a car. When the car enters the area covered by the radar beam that emits the radar, the radar receiver will automatically play the voice information of the relevant road immediately, so as to prepare the driver for the next step in advance.

Abstract

The invention relates to radar traffic pre-warning phonetic cueing device. Emission radar is set on the ground. The relevant radar phonetic pre-warning cueing signal can be broadcasted by the carried radar receiver for the driver at traffic crossing, hazardous location etc by radar antenna short distance phonetic wireless transmission technique which is more convenient, exact, and safer compared with the figure and words type information gained from the GPS carried radar screen display.

Description

Technical field: [0001] The invention relates to a radar, in particular to an early warning voice prompt radar for traffic safety. Background technique: [0002] The wave number is concentrated in the homi wave above 60GHz. The wavelength of this band is relatively short, and the antenna beam is narrow. Due to the high frequency, the Doppler band of the detection speed is accurate, and the radar system is small in size, allowing wireless and other devices to be designed smaller , easy to install on the car [1] . The millimeter wave 50GHz band antenna station can provide short-distance color TV signal, data fax and voice radio transmission, it can transmit 6.3Mbps digital signal, or analog image and voice signal, and the system can cover 10km or more under good atmospheric conditions Long transmission distance, considering the attenuation of rainy weather, the transmission distance is 1-3km [2] . [0003] The number of cars in our country is increasing at a rate of severa...
