Embodiment Construction

[0037] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0038] The specific implementation of the present invention will now be described by taking the mass data storage applied to a large-scale elevator safety management platform with districts and cities as an example.

[0039] Such as figure 1 As shown, first, each elevator to be monitored is equipped with a data acquisition host, and a large-scale elevator safety management platform with districts and cities as the unit is installed in the monitoring center. The data acquisition host is responsible for transmitting data to the memory database server cluster of the monitoring center. . An in-memory database server cluster is composed of multiple in-memory database servers. These multiple in-memory database servers operate in an unowned mode, that is, there is no centrally managed in-memory database server, and each in-memory database server is in a pa...

Abstract

The invention relates to the technical field of computer data storage, and discloses a massive data storage method, which comprises the following steps of: 1, obtaining a currently active memory database server list; 2, organizing data to be stored into a format storable for a database, and mapping the data to be stored into an annular Hash space, wherein the data also comprises a host Internet protocol (IP) address of a data source and an IP address of a destination memory database server; 3, mapping the IP address of the memory database server to the annular Hash space; and 4, establishing a mapping array for the Hash positions of two databases, namely a Hash position storage array for each virtual server of a database server, to obtain mapping relationships between the data, a virtual database and an actual database, and storing the data to be stored by pieces. The method is applied to the instant storage of massive data.

Description

technical field [0001] The invention relates to the technical field of computer data storage, in particular to a massive data storage method based on the combination of distributed hash table DHT and memory database storage. Background technique [0002] In recent years, "elevator horror incidents" have been frequently staged in major first-tier cities. Elevator deaths and injuries in Beijing, Shenzhen, Shanghai, Guangzhou and other cities have been reported continuously. To effectively prevent and resolutely curb elevator accidents, the elevator safety management platform came into being. The elevator safety management platform mainly realizes the remote dynamic detection, fault diagnosis and recording of the elevator operation. It can understand the operation status of the elevator in real time through the video. When the elevator encounters faults such as closing people, rushing to the top, and sinking to the bottom, it will be informed immediately and take timely measure...
