The inter-board data communication transmission method according to an embodiment of the present application further includes step S110.
Step S110: the first memory is internally provided with a second data area, the second data area comprises a plurality of third storage units, and the third storage units are in one-to-one correspondence with the second storage units.
In this step, a second data area is set in the first memory, where the second data area includes a plurality of third storage units, and the third storage units are in one-to-one correspondence with the second storage units, so that the content of the second storage unit is written into the third storage units in the subsequent step, and further, whether the data of the first storage unit and the third storage unit corresponding to the same second storage unit are the same is determined.

Step S410: the second board 120 sends a third message to the first board 110, where the third message includes third data and a third address, the third data is data of the second storage unit, and the third address is an address of a third storage unit corresponding to the second storage unit;
step S420: the first board 110 writes third data into the third storage unit based on the third message;
step S430: the first board 110 judges whether the data of the first storage unit and the third storage unit corresponding to the same second storage unit are the same, if so, the second message is confirmed to be successfully sent, otherwise, the second message is confirmed to be failed to be sent.
In this step, a third message is sent to the first board 110 through the second board 120, where the third message includes third data and a third address, the third data is data of the second storage unit, the third address is an address of a third storage unit corresponding to the second storage unit, and the first board 110 writes the third data into the third storage unit based on the third message, that is, copies the content of the second storage unit into the corresponding third storage unit, so as to implement data mirroring, so as to determine whether the data of the first storage unit and the third storage unit corresponding to the same second storage unit are the same, if so, it is confirmed that the second message is sent successfully, or else, it is confirmed that the second message is sent unsuccessfully.

It should be noted that, the first board 110 determines whether the data of the first storage unit and the third storage unit corresponding to the same second storage unit are the same in real time, so as to determine whether the second message is sent successfully. In the conventional inter-board data communication transmission method, the external device needs a preset response time, if the response time exceeds the response time and the successful transmission from the second board card 120 forwarded by the first board card 110 is not received, the transmission failure is confirmed, and because the baud rate of the communication between the external device and the first board card 110 is lower, the transmission speed is slow, the preset response time is relatively longer, and if retransmission is needed, the whole transmission process takes longer, and according to the inter-board data communication transmission method in an embodiment of the application, whether the second message is successfully transmitted can be judged in real time, and if the transmission failure occurs, the second message can be immediately transmitted again, so that the transmission time is reduced.
It should be noted that, the second board 120 sends the third message to the first board 110 in real time, in other words, after the second board 120 changes the data in the second storage unit, the third message is immediately sent to the first board 110, so that the data in the third storage unit in the second data area is updated in time and kept consistent with the corresponding second storage unit. The second board 120 may also send a third message to the first board 110 at regular time intervals.

According to the electronic device 100 of an embodiment of the present application, compared with the conventional inter-board data communication transmission method, the first message is recoded into the second message through the first board 110, and then the second message is sent to the second board 120, that is, the data of the first message is sent to the second board 120 in a non-transparent transmission manner, because the non-transparent transmission speed is faster than that of the transparent transmission, the transmission time is saved, if the second message fails to be sent, the second message is retransmitted through the first board 110, so that the first message is prevented from being retransmitted from the external device, the external communication link with long time consumption is reduced, and the communication efficiency is improved.
