Problems solved by technology

The contact speed measuring device mainly uses the strain sensor as a means of collecting signals, which can obtain a relatively high capture rate and is cost-effective. Its disadvantage is that it will damage the road surface during installation. The strain sensor is buried underground, so it is easily affected by the environment. In addition, it is easy to be damaged by heavy vehicles, road repairs, etc., and the actual maintenance cost is higher than other speed measuring devices; the non-contact speed measuring device is mainly a radar speedometer, which is easy to carry, but the cost is high. The performance is not stable

Embodiment 1

[0059] In the system structure involved in the present invention, there is mainly the communication between vehicles, which is completed by li-fi signal, the communication between li-fi base station 2 and the vehicle is completed by li-fi signal, and there is also li-fi signal The communication between the base station 2 and the total monitoring station 3 is completed by wireless network transmission.

[0060] according to figure 1 The monitoring flow chart that the shown embodiment of the present invention relates to, a kind of vehicle monitoring method based on li-fi communication technology, comprises the following steps:

[0061] S1. The signal receiving device 10 acquires an optical signal reflected by a nearby vehicle, and after acquiring the optical signal, converts the optical signal into an electrical signal and sends it to the first signal processing module 13;

[0062] Among them, the first signal processing module 13 is a series of single-chip microcomputer system...

Embodiment 2

[0088] The first embodiment introduces the communication between vehicles to determine whether the vehicle is safe; the second embodiment introduces the communication process between the vehicle and the li-fi base station 2 and between the li-fi base station 2 and the total monitoring station 3 .

[0089] S4, the first signal processing module 13 acquires the body information of the vehicle and sends the body information of the vehicle to the signal sending device 15, and the signal sending device 15 sends the information to the passing li-fi base station 2; the body information of the vehicle Including: owner information, vehicle information, vehicle weight, driving speed, driving end point and driving trajectory;

[0090] The specific car owner information includes the driver's license information, previous driving violation information, including speeding times information under li-fi monitoring, etc.; vehicle information includes the vehicle's use time, vehicle model, etc.;...

Embodiment 3

[0107] according to Figure 5The system structure schematic diagram shown is a system of vehicle monitoring method based on li-fi communication technology, including the body of the vehicle, and also includes:

[0108] Signal receiving device 10: the signal receiving device 10 is installed at the front and rear lights of the car, and the lights are LED lamp tubes, and one or several groups can be installed; used to receive the signal from the nearest li-fi base station 2, and receive signals from The optical signal reflected by the nearby vehicles, and converts the optical signal into an electrical signal and transmits it to the first signal processing module 13;

[0109] GPS detection module 11: the GPS detection module is installed on the vehicle body, used to record the driving track of the vehicle, and send the track data to the first signal processing module 13;

[0110] Weight detection module 12: installed on different road sections, used to detect the weight of the ve...

Abstract

The present invention provides a vehicle monitoring system and method based on li-fi communication technology, comprising the following steps: S1, a signal receiving device acquires an optical signal reflected by a vehicle nearby, and after acquiring the optical signal, converts the optical signal into an electrical signal for transmission To the first signal processing module; S2, the first signal processing module processes the electrical signal, and extracts the weight information of the front and rear vehicles contained in the signal, the vehicle initial speed information and the vehicle distance information; S3, the first signal processing module combines the vehicle weight of the main body Information and vehicle initial speed information, calculate the risk factor of the ontology; and make different responses to different calculation results. S4. The first signal processing module obtains the body information and sends the body information to the signal sending device, and the signal sending device sends the information to the passing li-fi base station; the body information includes: car owner information, vehicle information, vehicle weight, driving speed, end point and trajectory.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a vehicle monitoring system method based on li-fi communication technology. Background technique [0002] At present, there are mainly two types of motor vehicle speed measuring devices in my country, which are contact speed measuring devices and non-contact speed measuring devices. The contact speed measuring device mainly uses the strain sensor as a means of collecting signals, which can obtain a relatively high capture rate and is cost-effective. Its disadvantage is that it will damage the road surface during installation. The strain sensor is buried underground, so it is easily affected by the environment. In addition, it is easy to be damaged by heavy vehicles, road repairs, etc., and the actual maintenance cost is higher than other speed measuring devices; the non-contact speed measuring device is mainly a radar speedometer, which is easy to carry, but the cost is hig...
