Particularly, controller 1 and radio access node 4 wireless connections, radio access node 4 is directly connected with server 1, or be connected with server 1 by gateway forwards device 5.
In practice, gateway forwards device 5 can be there is no yet.When gateway forwards device 5 mainly exists signal blind zone between radio access node 4 and server 3, spread signal scope, is communicated with by radio access node 4, ensures all standing of signal in whole control range, and gateway forwards device 5 is easy for installation with server 3.
More specifically, the wireless connections based on SimpliciT1 agreement are adopted between controller 1 and radio access node 4.
Alternatively, radio access node 4 may be used for,
At least one controller 1 is waken up from resting state;
Obtain the environmental data of at least one controller 1 collection and environmental data is sent to server 3;
The control instruction of server 3 environmentally data genaration is sent to controller 1.
In actual applications, radio access node 4 can continue to monitor does not have new controller 1 to add or has do not have new packets need to forward.When there being new controller 1 to add (controller 1 is access radio access node 4 initially), radio access node 4 calling interface initialization function initializes controller 1.If there is new packet to be transmitted to server 3, radio access node 4 directly by Packet Generation to server 3.When there being new packet to be transmitted to controller 1, due in order to power saving, controller 1 generally can be in resting state, and therefore controller 1 first wakes up from resting state by radio access node 4, then by Packet Generation to controller 1.
Particularly, after controller 1 initializes, controller 1 transmits into network mark note (join token) to radio access node 4.Radio access node 4, after receiving join token, sends linkage flag (Link token) to controller 1.Controller 1, after receiving Link token, calls SMPL_Link function and sends Link request to radio access node 4.Radio access node 4, after receiving Link request, sends Link response to controller 1.Controller 1, after receiving Link response, calls SMPL_Send function and sends environmental data to radio access node 4.Radio access node 4, after receiving environmental data, forwards environmental data to server 3.Meanwhile, this Time Controller 1 also can receive instruction that server 3 that radio access node 4 forwards sends, gather actual temperature and actual humidity, to air-conditioning 2 sending controling instruction etc.Controller 1, after air-conditioning 2 sending controling instruction, enters resting state.
