[0002] With the rapid development of highways, the requirements for intelligent and information-based street lighting systems are becoming increasingly higher. Traditional highway street lighting systems mostly only have basic lighting functions, lack the ability to monitor the road surface in real time and perform data analysis, and are unable to provide effective data support for traffic control.

[0003] In recent years, the development of Internet of Things technology has made it possible to intelligentize highway streetlight systems. By applying sensors, wireless communications and other technologies to streetlight systems, real-time monitoring and control of highway networks can be achieved. However, most existing Internet of Things streetlight systems use a single communication method, and the reliability and stability of data transmission need to be improved. There are also problems such as incomplete data monitoring and untimely emergency response.

[0004] In addition, traditional street lighting systems often lack effective alarm and response mechanisms for various emergency situations that may occur on highways, such as traffic accidents, sudden weather changes, etc. Summary of the invention

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0039] Attached Figure 1 The invention is a flowchart of a highway OTFS transmission module street light method. DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] A best embodiment is given below:

[0042] like Figure 1As shown, a highway OTFS transmission module street lamp method in this embodiment includes multiple street lamps, each of which is provided with a signboard, a control terminal and a monitoring and dispatching center connected to the control terminal, and the monitoring and dispatching center and each street lamp are connected via a ZigBee network;

[0043] The street light controller transmits the status of the street light and signboard to the monitoring and dispatching center, which obtains the working status of the street light and signboard. The control terminal sends the control signal to each street light controller through the monitoring and dispatching center, and the controller on each street light performs corresponding operations according to the received control signal.

[0044] Each of the street lamp controllers includes a collection module, a first ZigBee module, a second ZigBee module, a WIFI module, a communication module, a display and an emergency alarm module;

[0045] The acquisition module sends the monitoring signal to the monitoring and dispatching center;

[0046] The first ZigBee module is connected to the acquisition module and sends the acquisition signal to the monitoring and dispatching center;

[0047] The second ZigBee module receives the acquisition signal sent by the first ZigBee module, and the emergency alarm module is connected to the monitoring and dispatching center through the first ZigBee module;

[0048] The WIFI module provides a WIFI hotspot, the communication module communicates with the mobile terminal, and the display is used to display images;

[0049] The emergency alarm module performs an emergency alarm.

[0050] Each street light controller also includes a weather monitoring module and a road status detection module;

[0051] The meteorological monitoring module monitors wind speed, wind direction, temperature, relative humidity, rainfall and visibility, and sends the real-time data of the monitored wind speed and direction, temperature, relative humidity, rainfall and visibility to the monitoring and dispatching center;

[0052] The road state detection module is used to detect the real-time data of road surface temperature, road surface relative humidity, road surface snow depth and road surface freezing, and send the detected real-time data of road surface temperature, road surface relative humidity, road surface snow depth and road surface freezing to the monitoring and dispatching center.

[0053] When a vehicle breaks down and stops on the highway, the mobile terminal connects to the nearest highway streetlight sign behind the vehicle to control the LED warning light to start, realizing the light warning function to remind the following vehicle that there is a fault ahead, thus ensuring driving safety on the highway;

[0054] When a high-speed moving car encounters an unexpected situation and needs to warn the following car, the LED warning light is activated by connecting the street light sign through the mobile terminal. In addition, the LED warning light of the device is set at a high position. Compared with the traditional warning sign, the position is higher, the warning effect is obvious, and the driver does not need to get off the car and walk on the highway to place the warning sign, which improves the safety of the driver.

[0055] Using the OTFS transmission module, first, the transmitted signal in the delay-Doppler domain is transformed into a time-frequency domain signal through ISFFT, and then transformed into the time domain using the Heisenberg transform. The time domain signal is sent to the receiving end via the time-varying signal. After the receiving end receives the time domain signal, it is transformed into a time-frequency domain signal through the Wigner transform, and finally the time-frequency domain signal is converted into the delay-Doppler domain through the SFFT. The time delay of signal propagation and the Doppler frequency shift caused by relative motion can be better captured in the delay-Doppler domain, especially in the fast time-varying channel, the signal processing capability is better than the time-frequency domain.

[0056] Based on the above method, a highway OTFS transmission module streetlight system in this embodiment includes multiple streetlights, each of which is provided with a signboard, a control terminal and a monitoring and dispatching center connected to the control terminal, and the monitoring and dispatching center and each streetlight are connected via a ZigBee network;

[0067] When a vehicle breaks down and stops on the highway, the mobile terminal is connected to the nearest highway street light sign behind the vehicle to control the LED warning light to start, realize the light warning function, and remind the following vehicle that there is a fault ahead;

[0068] When a high-speed moving car encounters an unexpected situation and needs to warn the following car, the LED warning light is activated by connecting to the street light sign through the mobile terminal.
