Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0026] see figure 1 , the present invention is used for the distributed calculation method of the water quantity of water supply and water charge, comprises the following steps:

[0027] S1: Establish a distributed memory database cluster. During implementation, the memory database cluster is set in more than three servers, and the more than three servers are interconnected through a network. For example: running on an X86 server, the number of servers is greater than or equal to 3, and the distributed deployment adopts a voting mechanism to elect the number of hosts when a server crashes. It can be a server connected by a LAN in the same computer room or a different one in a remote computer room connected by fiber optics. server.

Abstract

The invention discloses a distributed computing method and system for water supply and water charges. The method includes: establishing a distributed memory database cluster; determining the number of computing modules according to the number of user households; According to the user number, the water business data is extracted and allocated to different data sets in the memory database cluster; when the business data corresponding to the user number is prepared, add a data preparation mark to the corresponding user number in the distributed message queue; more than two The calculation module extracts the water business data for calculation according to the user number with the data preparation completion mark, writes the calculation result into the distributed memory database cluster, and writes the calculation result and the next processing measures back to the relational database. The present invention greatly improves the account calculation speed by adopting a distributed architecture.

Description

technical field [0001] The invention relates to the field of urban water supply billing, in particular to a distributed computing method and system for water supply water volume and water charges. Background technique [0002] With the expansion of the city and the transformation of water supply meters, the number of users under the jurisdiction of the water supply company has grown from more than 100,000 ten years ago to the current scale of one million. [0003] The traditional calculation of water volume and fee is handled by traditional application calculation combined with relational database storage. The traditional accounting calculation method (single program and multi-thread to obtain data, calculate and obtain results one by one according to the account), because of the single structure and simple algorithm leads to The real-time performance of water volume and water fee calculation is not enough. For example, the traditional calculation architecture and algorithm ...
