As shown in Figure 1, the embodiment of the automatic control method of the present invention includes the following steps:

S102, the control source device generates a control signal including a control source device address, a target device address, and an operation code, and sends it to the target device controller;

S104. The target device controller parses the control signal, and sends the operation information corresponding to the operation code to the target device corresponding to the target device address;

S106. The target device performs a corresponding operation according to the operation information.

The target device sends a feedback signal to the control source device after completing the corresponding operation. This feedback signal usually has two functions: one is the feedback on whether the control of the device is successful; the other is the response after reading the state of the device.

Among them, the control signal is shown in Table 1 below,

Table 1

The specific description of each part of the control signal is as follows:

1. Boot code

The boot code is the start flag of the data packet, which is fixed at 0xAAAA. When the receiving device receives the 0xAAAA flag in the data packet, it takes the next data as the packet length and starts to receive the entire SmartCloud data packet;

2. Packet length

Define the packet length;

When the length of the data packet is equal to 11, the additional data content is zero, and when the length of the data packet is greater than 11, the length of the additional data content=data packet length-11;

Data length range: 11-78;

The method of calculating the length of the data packet: the data length from sequence number 2 to 10, excluding the data of sequence 1;

3. Source subnet ID and source device ID

Indicate the address of the source device, each device has an address, including subnet ID and device ID, the range of source subnet ID is 0-254, and the range of source device ID is 0-254;

4. Source device type

Indicate the type of data packet sending device, 0-65535;

5. Operation code

Define various operation commands and information in the system, the value range is 0-65535, that is, up to 65535 operation commands and information can be defined;

6. Destination subnet ID

As shown in Table 2 below,

Table 2

The range value of the target subnet ID Function Description 0-254 Subnet ID 255 Broadcast all subnets

7. Destination device ID

As shown in Table 3 below,

table 3

The range value of the target device ID Function Description 0-254 Device ID 255 Broadcast all devices in the subnet, if the subnet ID is also 255, it is the whole network broadcast

8. Additional data

The content and length of additional data are determined by the operation code, and each operation code has a different meaning, content and length of additional data, which is a functional supplement to the operation code;

9. CRC high 8 bits and CRC low 8 bits

The CRC check result from "data packet length" to "data content" is used to check whether there is any data error in the transmission of the data packet, and the data of CRC check is from sequence number 2 to 9.

In this embodiment, control signals and/or feedback signals can be transmitted through RS232, RS482, RS485, TCP or UDP interfaces. The data packet structure of the control signal and the feedback signal will be specifically described below with specific examples.

1. Transmission of data packets on the RS232 or RS485 bus

Example 1:

Source Subnet ID: 1; Source Device ID: 6; Source Device Type: 7;

Target subnet ID: 1; Target device ID: 9; Target device is dimmer;

Opcode: 0x000E (read device notes);

Additional data: none;

The data packet of the control signal is shown in Table 4 below:

Example 2:

Source Subnet ID: 1; Source Device ID: 6; Source Device Type: 7;

Target Subnet ID: 1; Target Device ID: 9;

Operation code: 0x0002 (run lighting scene);

Additional data: none

Area code: 1

Scene number: 1

The data packet of the control signal is shown in Table 6 below:

Table 6

The data packet (scenario) of the target device feedback signal is shown in Table 7 below:

Table 7

Second, transmit data packets on the UDP network

When used on the UDP network, the sender's IP and packet header flag will be added in front of the original data packet.

There are two types of header flags, header A of the data packet: the ASCII value of HDLMIRACLE; header B of the data packet: the ASCII value of SMARTCLOUD.

For example: If the sender's IP address is: 192.168.0.111

A UDP packet using header A will be shown in Table 8 below:

Table 8

A UDP packet using header B will be shown in Table 9 below:
