Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In order to ensure the communication efficiency of the electronic price tags, there is usually a pairing and binding relationship between the electronic price tags and the base stations, so that each base station stores an electronic price tag list for its maintenance and management. The wireless communication network has the advantages of large business super-area, large quantity of electronic price tags and wide distribution space, and a plurality of base stations are required to form the wireless communication network capable of covering the business super-whole area. When a plurality of base stations work together, due to the limitation of the signal range of the base stations, when an electronic price tag is simultaneously positioned in the signal range of two or more base stations, how to intelligently seek the base station with better signal intensity to realize data communication, when the electronic price tag moves from an area A to an area B due to the adjustment of site layout, the electronic price tag is separated from the signal range of the base station in the area A, and if a flexible base station switching method is not adopted, the problems of electronic price disconnection, long time consumption in the reconnection process, influenced battery service life, untimely information updating and the like exist.
Referring to fig. 1, an embodiment of the present application provides an electronic price tag base station switching method based on the internet of things. The method comprises the following steps:
s10, detecting the strength of the heartbeat signal of the bound base station;
s20, recording the strength value of the bound base station signal;
and S30, if the strength value of the bound base station signal is greater than a set threshold, keeping the connection state with the base station, and reporting the communication state with the base station to a server.
In S10, the bound base station may be an electronic price tag bound base station.
In S20, the strength value of the bound base station signal may be detected and recorded by the electronic price tag, and the strength value of the bound base station signal may be sent to the server.
In S30, the server may store the set threshold. If the strength value of the signal of the base station bound by the electronic price tag is greater than the set threshold value, the strength of the signal between the electronic price tag and the corresponding bound base station is good enough at the moment, the base station does not need to be switched, and the connection condition at the moment can be uploaded to a server for recording.
According to the electronic price tag base station switching method based on the Internet of things, the strength of the heartbeat signal of the bound base station is detected, and then the strength value of the signal of the bound base station is recorded. And finally, if the strength value of the bound base station signal is larger than a set threshold value, the connection state of the bound base station signal and the base station signal is kept, and the communication state of the bound base station signal and the base station signal is reported to a server. If the strength value of the signal of the base station bound by the electronic price tag is greater than the set threshold value, the signal strength between the electronic price tag and the corresponding bound base station is good enough, so that the base station does not need to be switched automatically, and the electronic price tag and the base station can be guaranteed to have a good connection state.
In one embodiment, in S30, if the strength value of the signal of the bound base station is greater than a set threshold, the connection state with the base station is maintained, and the communication state with the base station is reported to a server, if the strength value of the signal of the base station is not greater than the set threshold, the strength value of the signal of the alternative base station is obtained, and if the strength value of the signal of the alternative base station is greater than the strength value of the signal of the bound base station, the connection is switched to the alternative base station.
When the electronic price tag is in the signal range of two or more base stations at the same time, the base station with the strongest signal needs to be switched to in time so as to ensure the stability and the accuracy of communication. And if the intensity value of the base station signal is not greater than the set threshold value. And the base station signal bound with the electronic price tag is not qualified at the moment. At this time, the surrounding alternative base stations can be automatically searched. If the strength value of the alternative base station signal is greater than the strength value of the bound base station signal, it indicates that the alternative base station signal is better at this time and also meets the predetermined requirement. Thereby switching the electronic price tag to communicate with the alternative base station.
In one embodiment, in S30, if the strength value of the signal of the bound base station is greater than a set threshold, the connection state with the base station is maintained, and the communication state with the base station is reported to a server, if the strength value of the signal of the base station is not greater than the set threshold, information of a neighboring candidate base station is obtained from the bound base station, and it is determined whether there are other candidate base stations, and if there are other candidate base stations, the strength value of the signal of the candidate base station is obtained.
That is, if the strength value of the base station signal is not greater than the set threshold, it indicates that the connection signal strength is not satisfactory at this time. The bound base station can be in communication connection with peripheral alternative base stations. And the information of the peripheral alternative base stations can be acquired through the bound base stations. And if the information of the peripheral alternative base stations can be acquired from the binding base station, judging that other alternative base stations exist. The step of obtaining strength values of the alternative base station signals may be performed at this time.
In one embodiment, before the connection to the alternative base station is switched, the method further includes recording stability of the alternative base station signal within a first preset time, and if the stability of the alternative base station signal within the preset time meets a predetermined requirement, switching to connect to the alternative base station. That is, if the strength value of the candidate base station signal is greater than the strength value of the bound base station signal, the stability of the candidate base station signal within the first preset time needs to be further determined. The first preset time may be 10 to 20 seconds. And if the stability of the alternative base station signal in the preset time meets the preset requirement, the alternative base station is stable at the moment. Thus handing over to the alternative base station.
In one embodiment, in the step S10, in detecting the strength of the heartbeat signal of the bonded base station, the strength of the heartbeat signal of the bonded base station is periodically detected. That is, the heartbeat signals of the bound base stations may be detected once at the same time interval.
Referring to fig. 2 and fig. 3, in one embodiment, the step S20, after recording the strength value of the bundled base station signal, further includes:
s40, if the variation of the strength value of the bound base station signal in a second preset time is greater than the moving threshold, determining that the electronic price tag is in a moving state, and further determining whether the strength value of the bound base station signal is greater than a set threshold;
and S51, if the signal intensity of the bound base station is greater than the set threshold, the bound base station is kept connected.
In S40, if a variation of the strength value of the bound base station signal within a second preset time is greater than a moving threshold, it indicates that the distance between the electronic price tag and the bound base station is changed. The variation of the intensity value in the second preset time is larger than the moving threshold, which indicates that the moving distance in the time period is larger. Therefore, the electronic price tag is judged to be in a moving state, and whether the strength value of the bound base station signal is greater than a set threshold value is further judged.
In S51, if the strength of the signal of the bundled base station is greater than the set threshold, it indicates that the signal is stable even though the electronic price tag moves, but the moving range is still within the effective signal coverage range of the bundled base station. No base station handover is required and therefore the connection with the bonded base station is maintained. In one embodiment, S52, if the strength of the signal of the bundled base station is less than the set threshold, then scanning for alternative base stations is started.
That is, when the signal strength of the bound base station is smaller than the set threshold, it indicates that the distance from the bound base station is far due to the movement of the electronic price tag, and the stability of the signal connection is affected. At this point, the bound base station needs to be adjusted, so the electronic price tag starts scanning for alternative base stations.
In one embodiment, the S52, if the strength of the signal of the bundled base station is less than the set threshold, further includes, after starting scanning for the alternative base stations:
and S53, selecting one of the candidate base stations with the maximum signal strength to establish connection.
Referring to fig. 4, in an embodiment, after determining that the electronic price tag is in the moving state, the method further includes indicating that the electronic price tag does not move any more when the position of the electronic price tag remains unchanged within a preset time. It will be appreciated that the location of the electronic price tag may be obtained by a positioning system, for example transmitted to a server via GPS. It will be appreciated that signal strength is not only related to distance, but also to the shielding effect of the surrounding building. Therefore, the strength of the signal cannot be determined simply by the distance. And if the signal intensity of the two base stations scanned by the electronic price tag is the same, determining the position relation between the two base stations with the same signal intensity and the electronic price tag, and then connecting the electronic price tag with the base station closest to the electronic price tag. Signal stability can therefore be improved with a high probability.
Let the coordinates of the base station A be (X1, Y1), the coordinates of the base station B be (X2, Y2), the angles of the electronic price tag receiving base station A and the base station B be theta 1 and theta 2, respectively, and the coordinates of the electronic price tag be C (X, Y), then
In one embodiment, the S53, after selecting the one of the candidate base stations with the highest signal strength to establish the connection, further includes:
and S54, reporting the communication state to the server. The communication process and the communication quality can be recorded through the server, and the functions of recording and real-time monitoring are achieved.
It should be understood that although the various steps in the flow charts of fig. 1-2 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-2 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.

In the recording module, the strength value of the bound base station signal can be detected and recorded through the electronic price tag, and the strength value of the bound base station signal can be sent to the server.
In the determination module, a set threshold may be stored in the server. If the strength value of the signal of the base station bound by the electronic price tag is greater than the set threshold value, the strength of the signal between the electronic price tag and the corresponding bound base station is good enough at the moment, the base station does not need to be switched, and the connection condition at the moment can be uploaded to a server for recording.
