Referring to fig. 3, the present invention provides a data interaction method, which can be applied to the target downlink base station 10, and when the method is applied to the target downlink base station 10, the following steps are implemented:
step S110: for a target downlink base station 10 of a plurality of downlink base stations, when a multicast heartbeat frame sent by the main control base station is not received again within a first preset duration after the multicast heartbeat frame sent by the main control base station is received, entering a preemption mode, and obtaining a target preemption main control heartbeat frame of the target downlink base station 10, wherein the target preemption main control heartbeat frame includes an identification number corresponding to the target downlink base station 10.
The target pre-occupation main control heartbeat frame includes an identification number corresponding to the target downlink base station 10.
It should be noted that, in a normal case, the master base station sends a multicast heartbeat frame to all downlink base stations managed by the master base station every a set time interval, and when the target downlink base station 10 does not receive the multicast heartbeat frame sent by the master base station again within a first preset time interval after receiving the multicast heartbeat frame sent by the master base station, it may be considered that the master base station fails, and the first preset time interval is greater than the set time interval.
It should be further noted that each downlink base station may send a pre-occupied main control heartbeat frame to other downlink base stations in the pre-occupied mode, so as to indicate that the downlink base station that sends the pre-occupied main control heartbeat frame may be used as the main control base station. The target pre-occupied main control heartbeat frame and other pre-occupied main control heartbeat frames are protocol frames so as to be convenient for transmission among all the down-hanging base stations.
In addition, in order to avoid a situation that the state of the master base station is misjudged due to a delay in the process of hanging the master base station 10 from the master base station during transmission of the multicast heartbeat frame, in this embodiment, the first preset duration is multiple times of the set duration, for example, 3 times, 5 times or 7 times, and is not specifically limited herein, and may be set according to actual requirements.
For example, in this embodiment, the master base station sends a multicast heartbeat frame to each downlink base station every 200 milliseconds, when the target downlink base station 10 receives the multicast heartbeat frame every time, it starts to count time, and if the counted time reaches 1 second and the multicast heartbeat frame sent by the master base station is not received again, it may be determined that the master base station is faulty, and the working mode of the target downlink base station 10 enters the preemption mode from the downlink working mode.
Step S120: and sending the target pre-occupation main control heartbeat frame to other downlink base stations, receiving other pre-occupation main control heartbeat frames sent by other downlink base stations, and comparing the identification number in the target pre-occupation main control heartbeat frame with the identification numbers of the other pre-occupation main control heartbeat frames.
It should be noted that, the identification number in the target preempted main control heartbeat frame is compared with the identification numbers in other preempted main control heartbeat frames to determine whether the identification number in the target preempted main control heartbeat frame is the maximum or the minimum.
Step S130: when the identification number in the target pre-occupied main control heartbeat frame is the maximum or the minimum, the target down-hanging base station 10 is changed from the pre-occupied mode to the main control working mode so as to manage other down-hanging base stations and carry out data interaction with the server.
Further, after performing step S120, the method further includes: when the identification number in the preempted main control heartbeat frame is not the maximum or the minimum, the target downlink base station 10 is changed from the preemption operation mode to the downlink operation mode.
Specifically, in this embodiment, when the identification number in the target master control heartbeat frame is the minimum, the working mode of the target downlink base station 10 is changed from the preemption mode to the master control working mode, so that when the working mode of the target downlink base station 10 is the master control working mode, the target downlink base station is used as a new master control base station, and in the process of being used as the master control base station, the multicast heartbeat frame is sent to other downlink base stations at set intervals, so that any one of the other downlink base stations can repeatedly execute the steps S110 to S130, thereby effectively ensuring that the cluster base station can perform reliable data interaction with the server. In addition, when the identification number in the target master heartbeat frame is not the minimum, the operation mode of the target downlink base station 10 is changed from the preemption mode to the downlink operation mode, so that the target downlink base station 10 is used as the downlink base station when the operation mode is the downlink operation mode.
Through the arrangement, when the cluster base station and the server are adopted for data interaction, the situation that the cluster base station cannot normally work due to the fault of the main control base station in the cluster base station is effectively avoided, in addition, the cluster base station can continue to work even if only one normal lower hanging base station exists, the reliability of the cluster base station is effectively improved, and the problem that the construction cost is high due to the fact that the main control base station needs to be maintained and replaced immediately when the main control base station has the fault is solved.
In order to avoid the situation that when the target downlink base station 10 receives other pre-occupied main control heartbeat frames sent by other downlink base stations, the other downlink base stations cannot send the corresponding other pre-occupied main control heartbeat frames to the target downlink base station 10 in time due to network delay, and further, a determination result that an identification number in the target pre-occupied main control heartbeat frame is the maximum or the minimum is not accurate enough, please refer to fig. 4, in this embodiment, the step S120 includes the following steps:
step S122: and sending the target pre-occupation master control heartbeat frame to the other downlink base stations and starting timing.
Step S124: and when the timing reaches a second preset duration, acquiring other pre-occupied main control heartbeat frames sent by other under-hung base stations and received by the target under-hung base station 10, and comparing the identification number in the target pre-occupied main control heartbeat frame with the identification numbers of the other pre-occupied main control heartbeat frames.
The second preset time period may be, but is not limited to, 30 milliseconds, 50 milliseconds or 80 milliseconds, and is not specifically limited herein, and may be set according to actual requirements.
Step S126: and when the identification number in the target pre-occupied main control heartbeat frame is the maximum or the minimum, obtaining the frequency of sending the target pre-occupied main control heartbeat frame, and when the frequency is less than the preset frequency, sending the target pre-occupied main control heartbeat frame to other downlink base stations again, starting timing, and returning to the step S124.
In this embodiment, step S126 may be to obtain the number of times of sending the target pre-occupied main control heartbeat frame when the identification number in the target pre-occupied main control heartbeat frame is the minimum. When the identification number in the target preemption main control heartbeat frame is not the minimum, the target downlink base station 10 changes its working mode from the preemption mode to the downlink working mode. The preset number of times may be, but is not limited to, 5 times, 10 times or 15 times, and is not specifically limited herein, and may be set according to actual requirements.
Step S130 specifically includes:
when the number of times of sending the target pre-occupied main control heartbeat frame reaches a preset number and the identification number in the target pre-occupied main control heartbeat frame is maximum or minimum, the target hang-down base station 10 is changed from the pre-occupied mode to the main control working mode.

when receiving the data forwarded by the master base station, the target downlink base station 10 sends the data to an external device.
The external device may be a terminal such as a computer, a tablet, a mobile phone, or any electronic device capable of communicating with the target downlink base station 10, and is not limited in particular.
