Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, system and medium for realizing hotel price monitoring based on a browser plug-in. Background Art

[0002] During the peak tourist season, hotel prices fluctuate significantly. This imbalance in supply and demand may lead to price increases that are beyond the tolerance of consumers, causing dissatisfaction with the hotel industry. It is particularly important to monitor hotel prices and promptly detect and intervene in unfair practices such as price fraud and price gouging.

[0003] However, existing hotel price monitoring technology has obvious shortcomings. Monitors need to manually visit the hotel website, record the price of each room type, and compare it with the historical price. This process is not only time-consuming and labor-intensive, but also may cause deviations in the recorded prices due to human factors. In addition, when prices fluctuate abnormally, it is necessary to take screenshots of the webpage and save them for subsequent evidence storage. These manual operations are not only inefficient, but also increase processing costs.

[0004] Therefore, the existing technology has the problems of low automation and low efficiency. Summary of the invention
