Method for realizing centralized data processing by monitoring terminal session through network

Abstract

The invention discloses a method for realizing centralized data processing by monitoring a terminal session through a network, belonging to the field of integration of computer software systems. The method comprises the following technical implementation steps of: monitoring the session process between a host and a terminal to obtain the IP (Internet Protocol) address and port number of the host as well as parameters such as the sending step, sending format and the like of relevant data; and developing a new system by using the parameters, wherein the newly-developed system can meet the localdata processing requirement and can be used for providing data for the original system under the condition of not changing the original host configuration. According to the method, the data can be well localized, the existing systems of an enterprise are integrated, the inconsistence of data source is prevented, troubles brought to operating personnel by system switching and equipment switching are prevented, repeated entering of the data and possible caused errors are reduced, and the production and office efficiencies of the enterprise are improved.

Description

technical field [0001] The invention relates to a realization method for transforming the host terminal mode by monitoring and analyzing the conversation process between the host and the terminal in the host terminal mode through network monitoring, belonging to the field of computer software system integration. Background technique [0002] The host terminal mode is suitable for centralized data processing mode systems, and is widely used in social pillar industries such as finance, telecommunications, and postal services. With the advancement of computer network technology, the communication between the terminal and the host is completed by the network card from the early RS232 or RS485 port, and the application field of the host terminal mode rapidly expands to emerging industries such as electricity, taxation, education, and government. The Telnet protocol is used for communication between the host and the terminal, which is especially suitable for production operating s...

Problems solved by technology

[0005] 1. If the data comes from manual collection, in order to prevent repeated data transmission, the terminal will delete the data in the collection device after transmitting the data to the host. If you want to keep these data, you need to develop another set of application software to process the peripheral data first. And this set of application software cannot run on the same machine equipment as the terminal, it is necessary to switch between the system and the equipment, and the system must run in order, if the two equipment are not on the same site, it will cause greater delay and other troubles
