Problems solved by technology

[0004] Most of the existing on-board multimedia devices replace the new playback content by replacing the memory chip or optical disc in the casing. This kind of on-board multimedia device has a serious shortcoming - the workload of card copying and card replacement is large, and the real-time performance of program updates is poor. , which seriously restricts the further development of vehicle multimedia equipment
In addition, there are also some systems or devices in the prior art that use wireless networks to update the content played by vehicle-mounted multimedia devices in real time. Although these systems or devices solve the above-mentioned shortcomings to a certain extent, most of them are implemented using 3G networks. Wireless communication, which brings disadvantages such as unstable signal and high price
Based on the above, there is still no suitable vehicle-mounted multimedia playback device or system in the prior art to be applicable to current mainstream public transport, such as public transport, railways, etc.

Embodiment 1

[0022] Please refer to figure 1 , which is a flow chart of a high-speed rail broadcast television and cognitive WiFi communication method disclosed by the present invention, a high-speed rail broadcast television and cognitive WiFi communication method proposed by the present invention, specifically comprising the following steps:

[0023] S1. Using a satellite TV antenna to receive satellite broadcast signals to obtain real-time image data.

[0024] S2. Pre-exchange the obtained real-time image data with the service proxy device through the Wi-Fi MAC layer link, and after the data pre-exchange is completed, the service proxy device passes the IP address specified in the MAC layer packet payload. Address, forwarding the data received in the pre-exchange to the vehicle-mounted satellite TV program server; wherein, before forwarding the data, the MSER algorithm and the exponential relationship transformation algorithm are used in combination for image processing to avoid distort...

Embodiment 2

[0028] Please refer to figure 2 , which is a second implementation flowchart of a high-speed rail broadcast TV and cognitive WiFi communication method disclosed in the present invention; in this embodiment, based on the high-speed rail broadcast TV and cognitive WiFi communication method disclosed in Embodiment 1, the difference is that In step S2, when the obtained real-time program data is forwarded to the vehicle-mounted satellite TV program server through WI-FI, the real-time program data is further stored in a database or a cloud server or other storable servers, and the terminal displays When the device is connected to the above-mentioned devices, it can obtain real-time program data and play it.

Embodiment 3

[0030] Please refer to image 3 , which is a third implementation flowchart of a high-speed rail broadcast TV and cognitive WiFi communication method disclosed in the present invention; in this embodiment, based on the high-speed rail broadcast TV and cognitive WiFi communication method disclosed in Embodiment 1, in order to avoid illegal users access to further ensure the confidentiality of information, an identity authentication mechanism is added in step S3, specifically:

[0031] When the terminal display device is connected to the vehicle-mounted satellite TV program server, the current server performs authentication based on the identity authentication rules, and if and only if the identity authentication is successful, the real-time image data is fed back to the display terminal, and the terminal display device can It is a display device such as a mobile phone, a tablet computer, a PC computer, etc., and the above-mentioned display device is wirelessly connected to the ...

Abstract

The invention discloses a high-speed rail broadcast television and cognitive WiFi communication method and system, and the method comprises the steps: firstly receiving a satellite broadcast signal through a satellite television antenna, and obtaining real-time image data; secondly, performing the data pre-exchange of the obtained real-time image data with a service agent device through a Wi-Fi MAC layer link, and after data pre-exchange is completed, enabling the service agent device to forward the obtained real-time image data to a vehicle-mounted satellite television program server; and finally, through terminal display equipment, when the vehicle-mounted satellite television program server is accessed through the WI-FI connection, selecting and obtaining the real-time image data and playing the real-time image data, wherein when the vehicle-mounted satellite television program server is accessed, an identity authentication rule is set in the current server to perform information authentication, and when and only when the identity authentication succeeds, the real-time program data is further fed back.

Description

technical field [0001] The present invention relates to the field of wireless communication, more specifically, relates to a high-speed rail broadcast television and cognitive WiFi communication method and system. Background technique [0002] The communication network of high-speed rail is a huge and complex network system. As the nervous system of high-speed rail, it is an important key technology of high-speed rail and an important driving force for the development of high-speed rail. [0003] In order to improve the ride comfort of passengers and reduce the fatigue caused by rides to passengers, most of the existing public transport vehicles are equipped with on-board multimedia equipment. [0004] Most of the existing on-board multimedia devices replace the new playback content by replacing the memory chips or CDs in the casing. This kind of on-board multimedia devices has a serious disadvantage-the heavy workload of card copying and card replacement, and poor real-ti...
