Specifically, the technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of thing for automatically selecting service node
Networked devices connection method, methods described include：
(1) in equipment end after electricity by the specified automatic Connection Service center of networking module, can initiate to obtain after successful connection
Take the request of available service node list；
(2) service centre can obtain service node state and the routing iinformation of details is obtained in connection procedure, according to
Routing iinformation uses the dispatching algorithm of optimal path, evaluation and the network connection stability of the service node；
(3) from the result calculated, selection evaluation highest service node is attached；
(4) at regular intervals, evaluation operation is re-started to all service nodes again, it is current to obtain in real time
The state of device network solicited status and the service node connected, when needed, handover network connects as early as possible, to ensure to set
It is standby to be stably connected with service centre's node, the stability not gone offline；
(5) a heartbeat packet periodically can be sent to service centre after equipment connects.
The present invention is further arranged to, and in (1), WIFI, Lora are connected to the domain name service specified by router,
Gsm module can initiate connection request to designated domain name.
The present invention is further arranged to, and in (2), service node state includes current node cpu loss, RAM takes
Than, hard disk EMS memory occupation ratio.
The present invention is further arranged to, and in (2), routing iinformation includes request frequency number, the device id of request and request
Equipment longitude and latitude.
The present invention is further arranged to, and evaluation highest service node is that current CPU occupancy is minimum, RAM occupancy is minimum, hard
The remaining most node of part internal memory.
The present invention is further arranged to, in equipment end selection communication protocol tcp/ip, mqtt, http or https and service
The heart communicates.
The present invention is further arranged to, and after service centre receives data, is saved into database；When APP or webpage please
After seeking data, the data conversion of preservation is returned to APP or web-page requests by node into readable data format.
The invention has the advantages that：
(1) flexibility of service node is good, according to the signal intelligence and EMS memory occupation of real network situation service node
Situation selects optimal service node；
(2) network stabilization, fed back according to network condition, assess the equipment connection of Internet of Things, internet of things equipment in real time
The network at end switches circuit in time when occurring unstable.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, it will use below required in embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for this area
For those of ordinary skill, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is service node network state detection and service state evaluation rubric figure.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The inventive method solve technical problem be：The service node for avoiding internet of things equipment connection from specifying, but according to
The network environment of itself, suitable service node is connected, and when service node goes out abnormal, can quickly be switched to other
Optimal service node.
By way of domain name mapping, during internet of things equipment connection server, the node specified is connected to, then passes through weight
The mode of orientation, the node closer with equipment is directed to, so as to reduce the delay of internet of things equipment and service node.
A kind of internet of things equipment connection method for automatically selecting service node, methods described include：
