The status information may be information such as the current state of the device 10 being turned on or off, the current temperature, and an abnormal message. The detecting device also compiles the status information into an RF signal, and the status information may be the detected physical quantity, for example, a carbon monoxide concentration.

The relay device 20 is located at the user end and is connected to the wireless base station 30 via a Wi-Fi signal to connect to the local area network in the user terminal. The wireless base station 30 is also connected to the Internet I, and can be wired to other devices in addition to the Wi-Fi signal. The relay device 20 is configured to receive the RF signal and convert it into a Wi-Fi signal for transmission, and receive the Wi-Fi signal and convert it into an RF signal for transmission. The relay device 20 is configured to receive the RF signals with status information sent by the devices 10, and obtain status information after being interpreted and stored in a memory (not shown). In addition, the relay device 20 has a first counter 202 and a second counter 204. The functions of the first counter 202 and the second counter 204 are described later.

In this embodiment, the electronic device 40 is a tablet computer that can be connected to the Internet I and connected via the Internet wireless base station 30, or directly connected to the wireless base station 30 in the regional network. The electronic device 40 has an application built in for the user to input control commands (such as turning on, off, adjusting temperature, etc.) of the control device 10. The user can specify the device 10 to be controlled through the application of the electronic device 40, and the electronic device 40 can transmit one or more control commands input by the user to the first via the Internet I or the regional network. a server 50, wherein the control command transmitted by the electronic device 40 includes an identifier of the relay device 20, at least one code of the device 10 to be controlled, and an instruction code (eg, turning on, off, and adjusting the temperature) The corresponding instruction code) is used to specify the relay device 20 and the device 10 to be controlled.

The first server 50 is a local server, and is connected to the local area network of the user terminal via the wireless base station 30. The first server 50 is connected to a first database 52. The first database 52 is connected to the first database 52. For recording the control command sent by the electronic device 40, and The control command to be sent is stored. The first server 50 and the first database 52 can be executed on the same server host or on two server hosts respectively.

With the above architecture, the data transmission method of the embodiment can be performed. The method includes the following steps, wherein: in conjunction with FIG. 2, the operation process of the relay device 20 is as follows:

In step S201, the relay device 20 is connected to the first server 50 via the regional network through the wireless base station 30, 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, by The relay device 20 transmits a first conversation command to the first server 50, wherein the first conversation command corresponds to the state information of the current relay device 20 not storing any device 10, that is, to the first servo. The device 50 indicates that the stateless information can be uploaded to the first server 50.

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 time is to ensure that the second chat command can be smoothly sent to the first server 50 to avoid the second occurrence Before the conversation command is sent to the first server 50, the first server 50 first closes the channel with the relay device 20, causing the first server 50 to fail to receive the second conversation command.

Please refer to FIG. 3 for the operation flow of the first server 50.

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.

Step S302, after receiving the data transmitted by the relay device 20, the first server 50 parses the type of the received data, wherein: if it is the status information of the device 10, the first server 50 will each time The received status information is stored in the first database 52 and updates the device status corresponding to the first database 52, and the corresponding device status information is transmitted to the electronic device 40. Returning to step S301, it continues to wait for receiving the material transmitted from the relay device 20.

If it is the first conversation command, the process returns to step S301 to continue waiting for 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 first server 50 closes the channel with the relay device 20 to interrupt the connection, waiting for the relay device 20 to reconnect or other relay device 20 In this way, the connection resources of the first server 50 are released, and when the structure of the plurality of relay devices 20 is made, the other relay devices 20 can be connected without being relayed by the original connection. The device 20 is exclusive.

If the status information of the device 10, the first conversation command, and the second conversation command are not representative of the received data format, that is, the data is lost during the transmission, the first server 50 transmits a third conversation command. (that is, requesting an interrupt instruction) to the relay device 20, and interrupting the connection with the relay device 20 after the transmission, wherein the third conversation command requests the relay device 20 to interrupt the first server 50 connection. In this embodiment, after the third conversation command is transmitted, the first server is started after a predetermined time. 50 interrupts the connection with the channel between the relay device 20, wherein the predetermined time is more than 1 second. 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 reconnects to the first server 50 via the regional network.

In the second embodiment, based on the first embodiment, in step S302, the first server 50 determines that the data from the relay device 20 is one of the status information and the first conversation command. The first server 50 determines whether there is currently a control command stored in the first database 52 from the electronic device 40 to be transmitted to any of the devices 10: if yes, the first server 50 transmits the control stored in the first database 52. Commanding to the relay device 20, after receiving the relay device 20, transmitting the control command to the corresponding device 10, causing the device 10 to perform corresponding operations; if not, the first server 50 transmits a fourth talk command to the relay. Apparatus 20, wherein the fourth talk command corresponds to a control command that is not to be transmitted to device 10.
