Method and system for monitoring equipment in real time through browser, and server

Abstract

The invention discloses a method and system for monitoring equipment in real time through a browser, and a WebSocket server. The method comprises the steps: building first connection between the WebSocket server and station terminal equipment, and receiving the state information transmitted by the station terminal equipment through the first connection; building a second connection with a client browser, and transmitting the state information of the station terminal equipment to the client browser through the second connection, so as to enable the client browser to initialize the contents of atarget monitoring webpage according to the state information; receiving the state change information transmitted by the station terminal equipment when the state of the station terminal equipment changes; and pushing the state change information to a client, so as to enable the client server to update the equipment state information on the target monitoring website according to the state change information. Therefore, the method truly achieves the full-duplex communication between the webpage and the server, achieves the active pushing of the new data to the client server, and reduces the load of the server.

Description

technical field [0001] The invention relates to the technical field of network data, in particular to a method, a system and a WebSocket server for real-time monitoring of equipment through a browser. Background technique [0002] At present, the technology used by most websites to realize instant messaging is polling. Polling is at a specific time interval (such as every 1 second), the browser sends an HTTP request (extensible hypertext transfer request) to the server, and then the server returns the latest data to the client's browser. [0003] However, implementing instant messaging through the traditional HTTP request mode will cause the browser to continuously send requests to the server. However, the traditional Http response contains a lot of redundant information, but the useful data contained in it may only be a small value, and the data obtained most of the time may be the same as the last time, which will take up a lot of bandwidth and waste a lot of server resou...

[0003] However, implementing instant messaging through the traditional HTTP request mode will cause the browser to continuously send requests to the server. However, the traditional Http response contains a lot of redundant information, but the useful data contained in it may only be a small value, and the data obtained most of the time may be the same as the last time, which will take up a lot of bandwidth and waste a lot of server resources. If many customers use browsers to send polls, then the server The load is heavy, and the response to customers is slow, which affects the customer experience
