Problems solved by technology

[0003] However, the disadvantage of the above-mentioned master-slave architecture (Client / Server) is that if there are too many clients and each client makes a data download request to the server at the same time, it will easily cause the server to be overloaded and the network bandwidth to be reduced. cause network downtime
Furthermore, if in order to avoid occupying too much bandwidth for the normal operation of the network, the number of read requests made by the client to the server is limited, or the interval between read requests between each client is extended, this will make the The client cannot obtain data in real time, and if the number of client settings increases, the real-time effect it produces will be reduced

Embodiment Construction

[0024] see figure 1 , which is used to show a system architecture block diagram of an embodiment of the data downloading system of the present invention. The automatic warehousing data downloading system of the present invention is constructed, for example, in a data kanban system with automatic control equipment, allowing clients to obtain data generated during the operation of the automatic control equipment through the automatic warehousing data downloading system. As shown in the figure, the automatic warehousing and downloading data system includes: a client 1 , an automatic control device 2 , and a server 3 .

[0025] The client 1 includes a plurality of terminal devices 10, 11, 12, and each terminal device 10, 11, 12 has an exclusive IP (Internet Protocol) address value to identify the terminal device 10, 11, 12 to which Network address, so as to facilitate the transmission and processing of data; and the automatic control device 2 has a database 20, which is used to s...

Abstract

A automatic stored data down transmitting method and the system, the client ends can download data only need the server carries on one time reading, when the client ends want to read automatic stored data, the end advances connection petition by TCP transmission control protocol to server, the server stores the IP address of ends in IP address temporary section, the server judges if it is the time to read data, if yes, the server read the data in data bank, and the data are transmitted to end according to the IP address by UDP user data information protocol, then the end advances a petition to end the connection, the server stops to transmit data to ends.

Description

technical field [0001] The present invention relates to a data reading technology applied to a master-slave architecture. More specifically, it relates to a method and system for automatic storage data downloading, which only requires the server to perform a reading action once for the client. Each terminal device that made a read request downloads the data. Background technique [0002] At present, a large amount of data is generally stored in a server (Server) for the client (Client) to download the data to their respective terminal devices, thereby reducing the cost required for data maintenance, update and transmission. In addition, in order to obtain real-time information and grasp the latest news at any time, terminal devices (that is, clients) with kanban functions are installed throughout the company, and data download requests can be made to the server that stores the latest information. [0003] However, the disadvantage of the above-mentioned master-slave archite...
