Dynamic device is installed on vehicle, and correspondence is installed on the fence of both sides of the road each light to guide article device respectively.
The structure of each light to guide article device is identical, controls chip, signal receiver and dual-colored LED lamp string including second,
The input terminal of output terminal connection the second control chip of signal receiver, the output terminal electrical connection dual-colored LED of the second control chip
Lamp string, also, maneuvering platform is communicatively coupled with signal receiver；Signal receiver is used to receive the control of maneuvering platform transmission
Signal processed, and be transmitted in the second control chip, the LED light string of the corresponding color of the second control chip controls dual-colored LED lamp string
It lights.Wherein, each light to guide article device has also included second source module, and thus second source module is entire light to guide article
Device provides working power, this second source module is solar powered module, including charge-discharge control circuit, accumulator and too
It is positive can solar panel, solar panel is installed in the outside of fence, accumulator, charge-discharge control circuit, the second control chip and
Signal receiver is assembled in same housing, and solar panel is electrically connected the input terminal of charge-discharge control circuit, charge and discharge
Control circuit is bi-directionally connected with accumulator, and the output terminal of charge-discharge control circuit is electrically connected red LED lamp string and green LED
Lamp string.In addition, in the present invention, same second source module, i.e. second source module can be shared with multiple light to guide article devices
Working power is provided to multiple light to guide article devices.
In the present embodiment, dual-colored LED lamp string is red LED lamp string and green LED lamp string, red LED lamp string and green
LED light string is connected to the corresponding output end of the second control chip, this red LED lamp strings the effect of warning, before expression
There is accident in side this side line road, and green LED lamp strings the effect of guiding, represents this side the coast is clear.
Wherein, each dual-colored LED lamp string on same fence is laid in along the length direction interval of fence on this fence respectively,
Each dual-colored LED lamp string on the fence of both sides is in face of setting.
Further, the length of each dual-colored LED lamp string is more than or equal to 20m, facilitates maneuvering platform that point occurs to accident
The dual-colored LED lamp string on periphery is controlled.
Early warning starter includes the first control chip, the first power module, GPS positioning module, impact microphone and nothing
Line transmission module, the respective input of the first control chip are electrically connected the output terminal and impact microphone of GPS positioning module
Output terminal, first control chip be communicatively coupled by wireless transport module and maneuvering platform, be by the first power module
Entire early warning starter provides working power, wherein, this first power module is powered using the power supply of vehicle.In addition,
This impact strength signal transmission is given the by this impact microphone for detecting the intensity (i.e. the size of accident) that automobile is collided
One control chip, with triggering the first control chip activity；The output terminal electrical connection first of GPS positioning module controls the corresponding of chip
Location information is transmitted to the first control chip by input terminal, this GPS positioning module to be positioned to current car position
In；First control chip is communicatively coupled by wireless transport module and maneuvering platform, the first control chip to be obtained
Car location message be transmitted in maneuvering platform.
First control chip has data comparison module, and the output terminal of impact microphone is electrically connected the defeated of data comparison module
Enter end, be provided with impact strength threshold value in this data comparison module, the shock that data comparison module detects impact microphone is strong
Degrees of data is compared with the impact strength threshold value in it, obtains corresponding comparison result, according to comparison result, the first control of triggering
Chip activity processed makes the first control chip still in dormant state.
Comparison result is：(1), when the impact strength of impact microphone detection is less than impact strength threshold value；(2), when hitting
When hitting the impact strength of sensor detection more than or equal to impact strength threshold value.When data comparison module is judged as (1), the
One control chip is still in dormant state；When data comparison module is judged as (2), the first control chip is triggered, GPS positioning

Wherein, when comparison result is (2), each dual-colored LED lamp string lights in the following manner：
For convenience of description, the front along the direction of running car for road, conversely, the rear for road, along running car
The fence of the both sides of the road in direction corresponds to left fence and right fence respectively, is occurred with unidirectional two track and automobile in right side road
For accident, accident vehicle location is starting point, and the red LED lamp cross luma on right fence in corresponding dual-colored LED lamp string rises, green
Color LED light string does not work, i.e., from the dual-colored LED lamp start of string on the right side fence closest to accident vehicle, towards accident vehicle
Rear multiple dual-colored LED lamp strings in red LED lamp cross luma rise, green LED lamp string does not work, right in the present embodiment
All red LED lamp strings light within the 150m corresponded at accident vehicle on fence, meanwhile, it is each double-colored on left fence
Green LED lamp string in LED light cross luma lights, and each red LED lamp string is corresponding with each green LED lamp string difference, in this way, after
Square vehicle can know that accident occurs for front in advance according to each red LED lamp string on right fence, then according on left fence
The guiding of each green LED lamp string changes to left side road in advance, to ensure the unimpeded of road, also, the secondary thing such as avoid knocking into the back
Therefore generation.
In addition, maneuvering platform can combine field condition and accident size is determined in accident vehicle how many distance range
Dual-colored LED lamp cross luma rises, in this way, when generation accident after, maneuvering platform controls the corresponding of accident vehicle corresponding section and its rear
Dual-colored LED lamp cross luma in distance range, i.e. red LED lamp string in the dual-colored LED lamp string of side light and opposite side
Dual-colored LED lamp string in green LED lamp string light.
Further, this early warning starter further includes start button, this start button electrical connection the first control chip
Respective input, manually to open road early warning and control system.
In the present invention, the first control chip and the second control chip are conventionally known chip, such as be can be used
AT89S52 chips.
The foregoing is merely the preferred embodiment of the present embodiment, all equivalent changes done with scope of the invention as claimed
And modification, scope of the presently claimed invention should all be belonged to.
