In order to improve the data acquisition rate of wireless communication, a multi-channel data transmission mode is mainly adopted at present, data transmission equipment has multiple wireless communication modes, and when the degradation of the transmission quality of a current data transmission channel is detected, other wireless communication modes with better transmission quality are switched, so that the problem of data loss caused by the degradation of a communication link is reduced.
However, although the current method for multi-channel data transmission can improve the data acquisition rate to a certain extent, in the current switching mechanism, if a communication protocol channel of a certain wireless communication protocol fails to transmit data, the communication protocol channel is switched to a communication protocol channel of another wireless communication protocol, and since the data failed to transmit is already used by the other communication protocol channel, the new communication protocol channel directly transmits the newly received data, and the data failed to transmit before is no longer transmitted, so that the data failed to transmit before is lost.

The first embodiment is as follows:
referring to fig. 1, a multichannel wireless communication method for a nuclear power plant according to an embodiment of the present application is described below, where the multichannel wireless communication method for a nuclear power plant according to the embodiment of the present application includes:
step S101, receiving data to be transmitted, and respectively storing the data to be transmitted into storage areas corresponding to preset wireless communication protocols;
in this embodiment, each preset wireless communication protocol has a corresponding storage area, and after receiving the data to be transmitted, the data to be transmitted may be backed up into multiple copies and stored in the storage areas corresponding to the preset wireless communication protocols, respectively.
The predetermined wireless communication protocol may be selected according to actual requirements, for example, the predetermined wireless communication protocol may be a point-to-point radio carrier transport communication protocol (VHF/UHF), a radio carrier transport communication protocol of a relay station, a General Packet Radio Service (GPRS) and other wireless communication protocols.
Step S102, selecting a data transmission channel from communication protocol channels corresponding to each preset wireless communication protocol according to a preset channel selection rule;
because there are multiple preset wireless communication protocols, each preset wireless communication protocol corresponds to one communication protocol channel, so that the data transmission channel can be selected from the communication protocol channels corresponding to the preset wireless communication protocols according to the preset channel selection rule.
Step S103, acquiring the data to be transmitted from the storage area corresponding to the data transmission channel and transmitting the data to an appointed receiver through the data transmission channel;
after the data transmission channel is selected, the data to be transmitted can be acquired from the storage area corresponding to the data transmission channel, and the data to be transmitted is transmitted to the designated receiver through the data transmission channel.
It should be understood that when the data transmission channel transmits data to be transmitted, only the data to be transmitted in the storage area corresponding to the data transmission channel is called, and the data to be transmitted in other storage areas is not affected.
Step S104, judging whether the data to be transmitted is transmitted successfully;
after the data to be transmitted is transmitted, whether the data to be transmitted is transmitted successfully can be judged.
Step S105, if the transmission of the data to be transmitted fails, switching a corresponding communication protocol channel according to a preset channel switching rule to serve as a new data transmission channel, acquiring the data to be transmitted from a storage area corresponding to the new data transmission channel and retransmitting the data, and repeating the execution until the transmission of the data to be transmitted succeeds or all the communication protocol channels fail to transmit.
If the transmission of the data to be transmitted fails, the corresponding communication protocol channel can be switched to serve as a new data transmission channel according to a preset channel switching rule, the data to be transmitted which fails to be transmitted is obtained from a storage area corresponding to the new data transmission channel, and the data to be transmitted is retransmitted.
And repeating the steps S103 to S105 until the data to be transmitted is successfully transmitted or all the communication protocol channels fail to transmit.
Further, the selecting a data transmission channel from communication protocol channels corresponding to each preset wireless communication protocol according to a preset channel selection rule specifically includes:
a1, in each scanning period, scanning each preset wireless communication protocol respectively, and selecting the communication protocol channel established first as the data transmission channel.
The current conventional channel selection rule is to set a main transmission channel, and the communication link state of the main transmission channel is degraded to switch the standby transmission channel, for example, when a point-to-point VHF/UHF protocol and a GPRS protocol exist, the point-to-point VHF/UHF protocol may be set as a main communication protocol channel, the GPRS protocol may be set as a standby communication protocol channel, and the link state of the communication protocol channel corresponding to the point-to-point VHF/UHF protocol is degraded to switch the communication protocol channel corresponding to the GPRS protocol.
However, in the channel selection rule, the link state of the main communication protocol channel is not necessarily optimal, and the standby communication protocol channel is switched only when the link state of the main communication protocol channel is degraded to a certain degree, although the continuous degradation of the link state of the communication protocol channel can be avoided by switching the communication protocol channel, and the data loss is reduced, the data acquisition rate is still low, for example, the data acquisition rate of a single wireless communication protocol is set to be about 60%, and the data acquisition rate can be increased to 70% -80% by switching the communication protocol channel, but the data acquisition rate is difficult to further increase because the communication protocol channel is switched only when the link state of the current communication protocol channel is degraded to a certain degree.
In contrast, in the channel selection rule provided in this embodiment, a scanning cycle is set, and after the multi-channel wireless communication device is started, the multi-channel wireless communication device can periodically scan, and in each scanning cycle, each preset wireless communication protocol is scanned, and a connection is established with each preset wireless communication protocol, and the establishment speed of the communication protocol channel with the better link state is faster, so that the communication protocol channel established first can be selected as a data transmission channel, and it is ensured that the communication protocol channel used in each scanning cycle is the communication protocol channel with the best link state, thereby reducing data loss as much as possible, improving the data acquisition rate, and through testing, the data acquisition rate is greatly improved, and can reach 98.9%, and can be applied to application scenarios such as nuclear power stations with extremely high data acquisition rate requirements.
Further, the method further comprises:
and B1, if all the communication protocol channels fail to transmit, storing the data to be transmitted into the storage areas corresponding to the preset wireless communication protocols again, setting the highest transmission priority, and waiting for the next scanning period.
In the process of transmitting data to be transmitted, if the data to be transmitted is successfully transmitted, the next data to be transmitted is transmitted, if the data to be transmitted fails to be transmitted in all communication protocol channels, the data to be transmitted which fails to be transmitted can be stored in the storage areas corresponding to the preset wireless communication protocols again, the highest transmission priority is set, the next scanning period is waited, after the communication protocol channels are established in the next scanning period, the data to be transmitted which fails to be transmitted is preferentially transmitted, and the occurrence of the situation that the data to be transmitted which fails to be transmitted is lost is further reduced.
Further, if the transmission of the data to be transmitted fails, switching a corresponding communication protocol channel according to a preset channel switching rule to serve as a new data transmission channel, acquiring the data to be transmitted from a storage area corresponding to the new data transmission channel and retransmitting the data, and repeatedly executing until the transmission of the data to be transmitted succeeds or all the communication protocol channels fail to transmit specifically includes:
c1, if the transmission of the data to be transmitted fails, selecting the next communication protocol channel as a new data transmission channel according to the sequence established by the communication protocol channels;
if the transmission of the data to be transmitted fails, the next communication protocol channel can be selected as a new data transmission channel according to the sequence established by the communication protocol channels.
C2, acquiring the data to be transmitted from the storage area corresponding to the new data transmission channel and retransmitting the data;
and after a new data transmission channel is selected, acquiring the data to be transmitted which fails to be transmitted from the storage area corresponding to the new data transmission channel, and transmitting again.
And C3, repeating the execution until the data to be transmitted is transmitted successfully or all the communication protocol channels are failed to transmit.
And if the data to be transmitted is successfully transmitted, transmitting the next data to be transmitted, and if the data to be transmitted fails to be transmitted, continuously selecting the next communication protocol channel as a new data transmission channel according to the sequence established by the communication protocol channels until the data to be transmitted which fails to be transmitted is successfully transmitted or all the communication protocol channels fail to be transmitted.
Further, the method further comprises:
d1, if the data to be transmitted is successfully transmitted, updating the storage area corresponding to each preset wireless communication protocol according to the successful transmission information.
When the data to be transmitted is successfully transmitted, the storage area corresponding to each preset wireless communication protocol channel can be updated according to the transmission success information, and the updating mode can be selected according to the actual situation, for example, the updating mode can be to delete the corresponding data to be transmitted according to the transmission success information, so that the storage space is saved, or the corresponding data to be transmitted can be marked as invalid data according to the transmission success information, so that repeated transmission is avoided.
In the multi-channel wireless communication method for a nuclear power station provided in this embodiment, each preset wireless communication protocol is provided with a corresponding storage area, when data to be transmitted is received, multiple copies of the data to be transmitted are backed up and stored in the storage areas corresponding to the preset wireless communication protocols, respectively, when a communication protocol channel corresponding to a certain preset wireless communication protocol is used for transmitting the data to be transmitted, only the data to be transmitted in the storage area corresponding to the preset wireless communication protocol is called, the data to be transmitted in other storage areas are not affected, when transmission fails, other communication protocol channels can be switched to serve as data transmission channels, the data to be transmitted corresponding to the communication protocol channel is retransmitted, the data to be transmitted cannot be lost due to the fact that the previous communication protocol channel calls the data to be transmitted, and the problem that in the process of switching the communication protocol channels in the existing multi-channel data transmission method is solved, the data which is failed to be transmitted can be lost, and the data acquisition rate is low.
When the data transmission channel is selected, a scanning period can be set, and the communication protocol channel established firstly is selected as the data transmission channel in each scanning period, so that the communication protocol channel with the optimal link state can be applied in each period, and the data acquisition rate is improved.
When the data to be transmitted is transmitted, if all the communication protocol channels fail to transmit, the data to be transmitted which fails to transmit can be stored in the storage areas corresponding to the preset wireless communication protocols again, the highest transmission priority is set, the next scanning period is waited, after the communication protocol channels are established in the next scanning period, the data to be transmitted which fails to transmit is preferentially transmitted, and the situation that the data to be transmitted which fails to transmit is lost is further reduced.
When the communication protocol channels need to be switched, the communication protocol channels can be switched in sequence according to the sequence established by the communication protocol channels in the scanning period.
When the data to be transmitted is successfully transmitted, the storage area corresponding to each preset wireless communication protocol can be updated according to the transmission success information, and the data to be transmitted which is successfully transmitted is prevented from being repeatedly transmitted.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
