Real-time push method and system of remote interaction display

Abstract

The invention discloses a real-time push method and system of remote interaction display, and belongs to the technical field of remote communication. The system comprises a PC upper computer and at least one remote interaction terminal, wherein each remote interaction terminal is connected with the PC upper computer through a network to achieve data communication, the PC upper computer comprises an administrator terminal and a server module, the administrator terminal is used for sending a command and data information to the server module, the server module is used for receiving the abovementioned information, updating the abovementioned information and then pushing the abovementioned information to the remote interaction terminal, the remote interaction terminal is used for displaying the abovementioned information to a user, and the user sends request inquiry information to the server module through the remote interaction terminal. By the system, automatic pushing of the remote interaction display and information is achieved, the power consumption of the system is reduced, meanwhile, the timeliness and the real-time performance of a notice are improved, information pushing has purpose and effectiveness, and the pushing efficiency is improved.

Description

technical field [0001] The invention relates to a remote interactive display real-time push method and system, belonging to the technical field of remote communication. Background technique [0002] Since 1996, PointCast Network first proposed the information push technology, and then major companies (Microsoft, Netscape) have studied it one after another, and its application fields have developed rapidly, from the initial Internet / Intranet to embedded fields, radio and television systems and The communication system also has multiple forms in which the original E-mail is extended to www in terms of application form. Foreign push technology covers mobile apps, and traditional websites are also using push to achieve real-time web effects. Foreign push technology charges a lot and is not widely implemented. [0003] However, my country's push technology is slightly later than that of foreign countries. In 1997, Beijing Century Group launched my country's first push product - ...

AI Technical Summary

Problems solved by technology

[0004] While the existing push technology plays a role in public places such as schools, factories, shopping malls, and hospitals, there are still many problems: such as push, aurora, pigeons, etc., users do not want to spend traffic on certain occasions, and network speed The problem is that the push message does not arrive in time

[0006] (1) Although printed slogans, light boxes, house numbers, etc. are easy to make and cheap, the displayed content cannot be changed, and the displayed content is single;

[0007] (2) Devices such as LED display screens and light arrays that cannot be connected to the Internet can change their display content, but only specific personnel can carry storage media to modify it on the spot. The operation is cumbersome, time-consuming and laborious, and the function is single and the application range is narrow;

[0008] (3) Devices such as networkable LED displays can be remotely modified, but most of them adopt the traditional C / S mode, which is not only expensive but also has a single function, narrow application range, and not strong real-time performance;

[0009] (4) The IPv4 address allocation efficiency used by the networked LED display screen is low (only 0.22%-0.33%), not suitable for wireless use, the image and sound are poor, and cannot be suitable for multimedia transmission, and the existing IPv4 addresses are not enough for allocation. There are a lot of problems in quality of service, security, multicast, mobility, etc.;

[0010] (5) In a certain occasion, push messages such as Getui, Aurora, and Carrier Pigeon cannot arrive in time, and the same content is sent to all users, regardless of time. The push has nothing to do with the jump, and the form and sound of the push remain unchanged , network delay

[0011] (6) Traditional locations use wired connection switches and manual adjustment of electrical appliances, which causes aging lines and waste of electric energy

Personnel counting adopts verbal roll call and paper sign-in, which is a waste of time and inaccurate

[0012] At the same time, the existing push technology adopts the traditional C / S structure, that is, the client and server structure, and adopts the polling method and the way of establishing a long connection. The polling method is that the CPU sends out inquiries regularly, and inquires each peripheral device in sequence. If you need its service, you will be given the service as soon as you have it. After the service is over, you will ask the next peripheral, and then continue to repeat itself; long connections are mostly used for frequent operations and point-to-point communications, and the number of connections should not be too many

Each TCP connection requires a three-step handshake, which takes time. If each operation is connected first, then the processing speed will be reduced a lot. The polling method requires the client to visit the server once in a while, to the client Caused a lot of pressure; and the long connection requires the Socket to be connected all the time, which puts a lot of pressure on both the client and the server, resulting in problems such as low transmission efficiency and poor real-time performance
