Problems solved by technology

[0006] However, for large-scale acquisition systems, the first method has low retrieval efficiency, while the second method has a high cost for updating the database located in the hard disk. Both methods will put a lot of pressure on the system, and cannot take both retrieval efficiency and system overhead

Embodiment Construction

[0021] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] like figure 1 As shown, the present invention relates to a terminal, a front-end computer, and a recall server. The recall server is provided with an initialization module, a recall strategy module, an order module, and an recall module, wherein the order module and the recall module are set in the memory of the recall server. . The terminal sends the data to the front-end processor at regular intervals. When the front-end processor responsible for message analysis and storage receives the message, parses and saves it, it notifies the RBI module of the callback server, and the RBI module The situation of the terminal number and the time point of the data is recorded at the corresponding position of the corresponding management table; the initialization module generates the management table located in the memory of the recall ...

Abstract

The invention discloses an internal memory dotting-based data calling method for an acquisition system, which relates to the technical field of information. The conventional large-sized acquisition system cannot improve search efficiency and reduce system overhead at the same time. The method is characterized in that: the system is provided with a calling server; the calling server is provided with an initialization module, a dotting module and a calling module; the initialization module periodically generates a next day dotting table in an internal memory; the dotting module dots at a corresponding position of the dotting table after a front-end processor informs the calling server of the receiving of a message; and the calling module calls information in the dotting table to call miss points according to the requirement on calling time. Dotting is performed on the dotting table of the internal memory, so that updating overhead of the dotting table is lowered and dotting table inquiry speed is high. The method is suitable for calling miss points of a large-sized acquisition system.

Description

【Technical field】 [0001] The invention relates to the field of information technology, in particular to a method for recalling data in an acquisition system based on memory management. 【Background technique】 [0002] At present, the data collection of the collection system can be divided into two communication methods: the master station survey method and the terminal active reporting method. No matter which method is adopted, incomplete data collection will inevitably occur. [0003] For the missing data, it is usually necessary for the main station to make a supplementary call. There are two ways to determine the recall point: [0004] Query from the data table reported by the terminal after storage and analysis, and find the points that should have but are not. [0005] The system builds a database in the hard disk, and after receiving the data reported by the terminal, it sets a mark (that is, a dot) at the corresponding position. When making up calls, query the data...
