Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 1 is a block diagram of a system according to an embodiment of the present invention. 101 represents a web crawler, 102 represents a hyperlink locker, 103 represents a webpage locker, and 104 represents a hyperlink giver.

[0020] The webpage crawler 101 is used for downloading webpages and processing webpages. Each web crawler 101 is independent of each other. At the same time, if only one web crawler is crawling web pages, it is obviously inefficient and cannot meet the real-time requirements. In order to improve the crawling speed, multiple webpage crawlers 101 are used to work simultaneously at the same time, thus greatly improving the crawling speed. The number of web crawlers 101 is usually determined by the ability of the hardware and the network environment conditions. A specific example is in figure 2 shown in . ...

Description

technical field [0001] The invention relates to a network data collection system, in particular to a distributed crawler cluster system. Background technique [0002] With the advent of the 21st century, information has grown explosively, and people are submerged in information garbage. In this situation, people propose and implement search engines in order to quickly extract useful information and improve work and study efficiency. As the basis of search engines and the only source of data processed by search engines, the status and importance of crawler systems are gradually highlighted. However, today's information updates are too fast, which requires increasing the crawling speed of crawlers to maintain a certain real-time search, and the speed of the current crawler system is far from meeting the needs of information updates. Therefore, improving the speed of the crawler system has become a focus of the current search field. At present, there is no systematic and effe...
