ibe 0;
Step S4, step S4-1, all street-lamp node cycle detection sensing datas, and periodically by their switch lamp of Internet of Things network transmission, vote to gateway; Step S4-2, gateway merges these vote information, in conjunction with the ballot weighted value of each street-lamp node, determines to turn on light or turn off the light, and concrete grammar is to calculate votes, V=∑ ζ
i* λ
i, and V being compared with threshold value T, T is the threshold value of a switch lamp votes arranging in gateway in advance.
Step S5, step S5-1, gateway determines to turn on light or turn off the light according to the comparative result of votes V and T, if V is greater than T, turns on light, otherwise turns off the light; Step S5-2, gateway is broadcast to all street-lamp nodes in this network by the decision-making order of switch lamp; Step S5-3, street-lamp node is controlled the corresponding actions of its street lamp according to the switch lamp order of receiving.
With reference to Fig. 8, the interworking method step in system of gateway and standby gateway is as follows:
Step P1, all street-lamp nodes have been stored a network number A and a network number B, and network number is to be solidificated in the flash memory of street-lamp node.The network number of gateway is set to A by software, and the network number of standby gateway is set to B by software.
Step P2, while starting working, it is in the network set up of the gateway of A that all street-lamp nodes can first join network number, carries out street lamp control work with gateway network consisting.
Step P3, if gateway breaks down, all street-lamp nodes repeatedly attempt joining that just to start to attempt to join network number after gateway failure be in the network that forms of the standby gateway of B, carry out street lamp control work with standby gateway network consisting.
Step P4, the periodical communication of monitoring central server and gateway and standby gateway, understands their operating state and the operating state of all street-lamp nodes.If gateway or standby gateway and monitoring central server are out of touch, server sends corresponding audible alert, and prompting monitor staff need to carry out site inspection maintenance, and the network number identical with original gateway only need to be set while if desired changing gateway; If there is street-lamp node polled data not to be sent to for a long time to gateway or standby gateway, they send to monitoring central server by this message, and server sends corresponding audible alert, and prompting monitor staff need to carry out on-site maintenance.
Step P5, if standby gateway breaks down, gateway replaces standby gateway and street-lamp node to carry out work, and standby gateway can be keeped in repair or change.
