The first server 50 and the second server 52 can be executed on the same server host or on two server hosts respectively, and the second server 52 and the database 56 can also be on the same server host or respectively. The server is executed by the host server, and the third server 54 can be executed on the same server host as the second server 52 or on the two server hosts.

The data transmission method of the embodiment can be performed by the above-mentioned architecture. The method includes the following steps: wherein, in conjunction with FIG. 2, the flow of the relay device 20 is performed: step S201, the relay device 20 transmits The wireless base station 30 is connected to the first server 50 via the Internet I, so that the relay device 20 and the first server 50 can mutually transmit data.

Step S202, the relay device 20 determines whether there is currently stored state information transmitted by any device 10: if yes, the relay device 20 transmits the stored state information to the first server 50; If not, the first conversation command is transmitted by the relay device 20 to the first server 50, wherein the first conversation command corresponds to the current relay device 20 not storing the status information of any device 10, that is, The first and second servers 50, 52 indicate that the stateless information can be uploaded.

Step S203, after the relay device 20 transmits the status information or the first chat command, the relay device 20 transmits a second chat command (ie, requests an interrupt command) to the first server 50, and interrupts after the transfer. The connection between the first server 50, wherein the second conversation command requests the first server 50 to disconnect the connection with the relay device 20. In this embodiment, the connection between the channel and the first server 50 is interrupted by the relay device 20 after a predetermined time has elapsed after the second conversation command is transmitted, wherein the predetermined time is 1 second or longer. 1 second is to ensure that the second chat command can be smoothly sent to the first server 50 to prevent the first server 50 from being turned off and the relay device before the second chat command is sent to the first server 50. The 20 channels cause the first server 50 to fail to receive the second talk command.

Please cooperate with FIG. 3 to operate the first server 50 and the second server 52.

In step S301, after the connection is continued in step S201, the first server 50 waits to receive the data transmitted by the relay device 20. After receiving the data transmitted by the relay device 20, the first server 50 transfers the data transmitted by the relay device 20 to the second server 52 for processing, and maintains connection with the relay device 20.

Step S302, the second server 52 parses the type of the received data, wherein: if it is the status information of the device 10, the second server 52 stores the received status information in the database 56 and updates the data. The device status corresponding to the library 56 continues to wait for receiving data transmitted by the relay device 20. The third server 54 transfers the device status from the database 56 to the electronic device 40.

If it is the first conversation command, the second server 52, which represents the status information without the device 10, continues to wait for receiving the data transmitted by the relay device 20.

If it is the second conversation command, on behalf of completing the transmission of the data, the second server 52 notifies the first server 50 to close the channel with the relay device 20 to interrupt the connection, and wait for the relay device 20 to reconnect or other. The relay device 20 is connected, whereby the connection resources of the first server 50 are released, and when the plurality of relay devices 20 are constructed, the other relay devices 20 can be connected without being connected. The originally connected relay device 20 is exclusive.

If the status information of the device 10, the first conversation command, and the second conversation command are not representative, the data format is not satisfied, that is, the data is lost during the transmission, and the second server 52 transmits a third conversation command. (ie, requesting an interrupt instruction) to the first server 50, and the relay device 20 is relayed by the first server 50. After the first server 50 transmits the third conversation command, the first server 50 interrupts the connection with the relay device 20, wherein the third conversation command requests the relay device 20 to interrupt The connection of the first server 50. In this embodiment, the connection between the channel and the relay device 20 is interrupted by the first server 50 after a predetermined time has elapsed after the third conversation command is transmitted, wherein the predetermined time is 1 second or longer. The time of 1 second is to ensure that the third conversation command can be smoothly sent to the relay device 20 to prevent the relay device 20 from being turned off and before the first server 50 before the third conversation command is sent to the relay device 20. The channel causes the relay device 20 to fail to receive the third talk command. After receiving the third conversation command, the relay device 20 returns to step S201 and connects to the first server 50 via the Internet.

In the second embodiment, based on the first embodiment, in step S302, the second server 52 further determines that the data from the relay device 20 is one of the status information and the first conversation command. The second server 52 determines whether at least one control command from the electronic device 40 to be transmitted to any of the devices 10 is currently stored in the database 56: If yes, the second server 52 transmits the control command stored in the database 56 to the first server 50, and transmits it to the relay device 20 via the first server 50. After receiving the relay device 20, the control command is sent to the relay device 20. The corresponding device 10 causes the device 10 to perform corresponding operations; if not, the second server 52 transmits a fourth chat command to the first server 50, and is transferred to the relay device 20 via the first server 50. The fourth chat command corresponds to a control command that is not to be transmitted to the device 10.
