Embodiment Construction

[0091] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0092] A real-time data storage and query system of a subway monitoring system proposed by the present invention, such as figure 1 as shown,

[0093] The system consists of clients, forwarding agents, routing agents, service nodes, real-time master and backup machines and monitoring services.

[0094] Specifically, the real-time master and backup machines are used to store the real-time monitoring data of the subway monitoring system. The real-time master and backup machines adopt the deployment mode of Redis master and backup machines plus sentinels. The machine (R2) is configured with two sentinels, and the standby machine performs real-time replication to the main machine.

[0095] Clients refer to programs that need to access real-ti...

Abstract

The invention discloses a real-time data storage and query system and method for a subway monitoring system, and the method comprises the steps of employing a field digital mapping method to map equipment and a point model into digital identifications, designing different storage modes, greatly reducing the consumption of a memory, and improving the access efficiency of a field; and when the client queries data, enabling the routing agent to generate a corresponding service node route according to the request rate and the vacancy processing rate of the node, querying a local point table cacheof the preferred access service node, and if the point is not in the cache, enabling the proxy service of the service node to perform secondary routing mapping according to a rule to access the real-time host, so that the query efficiency and flexibility are improved.

Description

technical field [0001] The invention relates to a real-time data storage and query system and method of a subway monitoring system, belonging to the technical field of rail transit monitoring systems. Background technique [0002] With the development of automation and information technology, the number of collection points in the comprehensive monitoring system of the subway environment has increased geometrically, which puts forward higher requirements for the storage and query efficiency, reliability and concurrency of real-time data in the system. [0003] At present, the monitoring system of the subway environment adopts simple real-time data memory storage and access. The disadvantages of this processing method are: with the increase of collection points, the system memory of the host will be greatly consumed; the increase of application layer queries makes it difficult for the system to process and issue requests efficiently; Deployment also lacks simple and efficien...
