A large-scale IoT terminal heartbeat monitoring method

Abstract

The invention provides a large-scale IoT terminal heartbeat monitoring method. The terminal device sends a request for establishing a websocket connection to a server, creates a websocket connection, and sets up a service middleware; the service middleware sets heartbeat reference data for each terminal device, and establishes Local heartbeat table, the terminal device and the server maintain a long connection by regularly sending heartbeat data; when a large-scale terminal device initiates a reconnection request to the server, a websocket reconnection mechanism is established to avoid high concurrency problems on the server. It solves the problems in the prior art, such as low performance, control delay, out-of-sync messages, very large network overhead, waste of network bandwidth resources, burden on services, and impact on customer experience.

Description

technical field [0001] The invention relates to the fields of financial services and heartbeat reconnection, in particular to a heartbeat monitoring method for a large-scale IoT terminal. Background technique [0002] With the improvement of people's living standards, more and more people choose financial services to invest through various terminal devices. In order to implement push technology, many websites use Ajax polling. This traditional mode brings obvious shortcomings, that is, the browser needs to continuously send requests to the server. However, the HTTP request may contain a long header, and the really valid data may be only a small part, which is obviously wasteful. Many bandwidth and other resources not only have low performance, but also have problems such as control delay and out-of-sync messages, which are very costly to the network. Moreover, when the user does not operate the page, it is easy to cause the problem of Websocket information disconnection. ...

AI Technical Summary

Problems solved by technology

[0005] By providing a large-scale IoT terminal heartbeat monitoring method, the present invention solves the problem of low performance, control delay, out-of-synchronization of messages, very large network overhead, waste of network bandwidth resources, and burden on services in the prior art. , Affecting customer experience and other issues, realized lightweight development, completely based on static pages, no server-side code, high operating efficiency, the front-end uses a heartbeat detection mechanism to ensure that the link can always keep in touch, because it is detected on the client side, Therefore, the burden on the server can be reduced without affecting the customer experience.
