Example one
Fig. 3 is a flowchart of a first embodiment of the electronic price tag network detection method of the present invention. An electronic price tag network detection method, comprising:
s1, under the electronic price tag network, any one new base station is scheduled to transmit radio waves under a preset frequency in the plurality of base stations;
s2, determining the adjacent relation between all other base stations and the new base station according to the receiving states of all other base stations to the radio waves;
s3, determining the set of neighbor relations between each new base station and all other base stations one by one among the plurality of base stations;
s4, generating a finite undirected graph of the connection relation among the base stations according to the adjacent relation set, and distributing the working frequency corresponding to each base station in the base stations according to the finite undirected graph.
In this embodiment, first, under the electronic price tag network, any new base station is scheduled to transmit radio waves at a preset frequency in a plurality of base stations; then, determining the adjacent relation between all other base stations and the new base station according to the receiving states of all other base stations to the radio waves; then, determining the adjacent relation set of each new base station and all other base stations one by one in the base stations; and finally, generating a finite undirected graph of the connection relationship among the base stations according to the adjacent relationship set, and distributing the working frequency corresponding to each base station in the base stations according to the finite undirected graph.
Specifically, in this embodiment, for example, the radio interference situation between the base stations is automatically detected by unified scheduling of a server or a central node, for example, three base stations, that is, a base station a, a base station B and a base station C, the server or the central node first calls the base station a to transmit a radio wave on a frequency, then controls the base station B and the base station C to receive the radio wave transmitted by the base station a on the frequency, and then, if the base station B or the base station C can receive valid data within a certain time, the base station a and the base station B are considered to be adjacent, or the base station a and the base station C are adjacent, and similarly, the server or the central node controls the base station B to transmit a radio wave on a frequency, and at the same time, controls the base station a and the base station C to receive the radio wave transmitted by the base station B on the frequency, thereby detecting the base station B and the base station a, and then, the graph is dyed by utilizing a four-color principle, and different colors represent different frequencies distributed to the base station, so that the aim that the adjacent base stations cannot be distributed to the same frequency is fulfilled.
It can be understood that, in this embodiment, through the adaptive planning of the electronic price tag network, the automatic allocation and intelligent management of the channels are implemented, where a server or a central node serves as a central administrator and is responsible for allocating the channels to the newly networked base stations, monitoring the network operation status, and adjusting the channel allocation of the base stations in time, and in this process, the portion of the gateway participating in the network entry is embodied in the service flow of the new base station.
