Embodiment Construction

[0020] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] Such as image 3 As shown, a distributed full-automatic hot standby server switching system across computer rooms of the Internet of Things, 3 servers, each of the 3 servers are electrically connected through the Internet and each intelligent node in the Internet of Things, and the 3 servers are set The priority level, and determine the main server and the standby server according to the priority level. The main server regularly transmits the updated data in the database of the main server to the standby server. The three servers send heartbeat packets to each other and know the current status of other servers. When the main server In case of failure, accordi...

Abstract

The invention discloses an internet of things across-machine room distributed type full automatic hot standby server switching system which comprises N servers. All servers are electrically connected through each intelligent node in the internet and the internet of things. A priority level is set in the N servers, and a master server and standby servers are determined according to the priority level. Updated data in a data bank of the master server is transmitted to the standby servers by the master server at a fixed time. Heartbeat packages are mutually sent among the N servers, so that each server can know current states of other servers. When the master server is broken down, an online server with the highest priority is automatically switched as a new master server according to the priority level. The intelligent node in the internet of the things automatically chooses and connects with the server which has the highest priority level to transmit data. Therefore, the purposes of automatically switching the servers, safe and saving cost are achieved.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an Internet of Things cross-machine room distributed fully automatic hot standby server switching system. Background technique [0002] At present, the Internet of Things is to connect any object to the Internet through various sensing technologies (RFID, sensors, GPS, cameras, laser scanners, etc.), various communication methods (wired, wireless, long-distance and short-distance, etc.) , to realize remote monitoring, automatic alarm, control, diagnosis and maintenance, and then realize a network integrating "management, control and operation". [0003] In the existing IoT architecture: all sensors or controllers that can parse digital protocols are called smart nodes, and nodes without this function are often mounted on a "proxy gateway" to become a large smart node . Smart nodes can communicate with each other, and most of the data will be transmitted to remote servers t...
