and if the target channel is a public network channel, sending a data access request of the continental server to the overseas central control machine based on the IPsec tunnel mode.
7. The method of claim 2, further comprising:
receiving data access request response data returned by the overseas central control machine;
and forwarding the data access request response data to a continental server according to the continental server information in the configuration file.
8. The method of claim 1 wherein there are at least two continental governors, including a primary continental governor and a backup continental governor; the number of the overseas central control machines is at least two, and the overseas central control machines comprise a main overseas central control machine and a standby overseas central control machine.
9. A data transmission apparatus, wherein the apparatus is provided in a continental control machine, the apparatus comprising:
the detection module is used for sequentially detecting the communication quality of the candidate channels according to the detection sequence in the configuration file;
the target channel determining module is used for taking a candidate channel with communication quality meeting a preset condition as a target channel; the candidate channels comprise a telecommunication internal network special line channel, a telecommunication public network channel, a communication internal network special line channel, a communication public network channel, a multi-line internal network special line channel and a multi-line public network channel;
and the sending module is used for sending the data access request of the continental server to the overseas central control machine through the target channel so that the overseas central control machine can forward the data access request to the overseas server.
10. A data transmission device, characterized in that the device comprises:
one or more processors;
a memory for storing one or more programs;
when executed by the one or more processors, cause the one or more processors to implement the data transmission method of any one of claims 1-8.
