Problems solved by technology

[0002] On the expressway, once the fog fills the air or the vision is limited at night, it often causes car rear-end collision accidents. The current measure is to install anti-fog lights at the rear of the car, but this measure cannot effectively prevent rear-end collisions. Car crashes, therefore, leave room for improvement

Embodiment 1

[0025] see figure 1 , figure 2 , where 1, 2, and 3 are three consecutive ground signal transceiver stations, and 4, 5, and 6 are ground signal transceiver stations separated by several intervals. Each station has signal input and output connections as shown by the arrows. Among the figure, 7 is the indication early warning equipment on the panel in the car, 8 is the front car on the forward direction, and 9 is the rear car; the radio signal transceiver 10 installed on the front car, the launch radius of its transmission frequency fa1 is to cover at least one The receiving device of the ground signal transceiver station is limited, and no more than three are the best, as shown in the dotted line on the left side of the figure; Pass to the input end of the ground signal transceiver station 4 that is separated by several stations and set the distance; each ground signal transceiver station is connected backwards in turn at the same interval, see figure 1 . The transmitting de...

Embodiment 2

[0034] see Figure 4 . On a four-lane expressway, the up and down lanes are two lanes respectively, and one lane is four meters wide. On the isolation belt in the middle of the road, ground signal transceiver stations are set up at intervals of 15 meters; each ground signal transceiver station is equipped with eight sets of transceiver devices, and there are two transceivers on each lane of cars, with four different transceiver frequencies. There are two sets of transceivers for a car in a certain lane, one set of transmitting frequency fa1 and receiving frequency fa2, the other set of transmitting frequency fb1 and receiving frequency fb2; the frequency of the two sets of transceivers on the ground signal transceiver station corresponds to it.

[0035] The early warning signal display is also set on the automobile; the early warning signal display can be a voice alarm or a text display.

[0036] The invention realizes the secondary early warning when the distance of vehicle...

Abstract

The present invention discloses warning method and signal system for preventing tail collision accident of automobile. Serial ground signal transmitting and receiving stations are set along highway, radio network is set, and interactive transceiver is set in automobile. After some ground signal transmitting and receiving station receives the signal from automobile in certain distance, the station transmits the signal in wired mode backwards to one other station in set distance, the other station emits the signal in one automobile received frequency and the automobile within the set distance can obtain the warning information of prompting the existence of front automobile. The present invention can prevent tail collision accident of automobile effectively.

Description

technical field [0001] The invention relates to the field of traffic safety, in particular to an early warning method for preventing automobile rear-end collision and a signal system thereof. Background technique [0002] On the expressway, once the fog fills the air or the vision is limited at night, it often causes car rear-end collision accidents. The current measure is to install anti-fog lights at the rear of the car, but this measure cannot effectively prevent rear-end collisions. Car crashes, therefore, leave room for improvement. Contents of the invention [0003] The purpose of this invention is to propose a kind of early warning method and early warning signal system for preventing automobile rear-end collision, to overcome the deficiencies in the prior art, prevent automobile rear-end collision accident. [0004] The present invention is based on the wireless network, the vehicle interacts with the ground signal transceiver station, and the ground signal transc...
