Therefore, electronic class cards are gradually moved into various campuses and are favored and favored by people at present.
In the prior art, after the electronic class cards are installed, the electronic class cards need to be registered in a background management system for centralized distributed management. The existing system generally comprises an electronic class board and a server, the version or the content of the server can be updated irregularly, and at the moment, the corresponding electronic class board also needs to be updated correspondingly; for the above information update operation, the conventional method is: and each electronic class board polls the server, and if the server has update information, the server sends the update information to the electronic class boards for updating. Obviously, the method has high flow requirement on the server and generates huge pressure on the server; especially, when the number of electronic class cards is large, the stress on the server in this way is very large, and even the server is crashed.
On the other hand, when the electronic class card is used for a period of time, batch information update is needed to be performed on the electronic class card, for example: the grade of a school is 10 grades, 10 electronic class cards correspond to the grade, after one year, the grade of the school is increased from one grade to two grades, and the grade information of the 10 electronic class cards needs to be updated uniformly. In order to solve the technical problem, in the conventional method, each electronic class board polls the server, and then the server sends the update information to the electronic class board terminal. Obviously, the method also has the problems of high server pressure and high traffic pressure.
Therefore, a convenient and quick information updating method and system are developed to realize information updating of large-scale equipment, reduce the manual burden, reduce the pressure of a server and flow, enhance the flexibility of management, and obviously have positive practical significance.
