Figure 3 As shown, the method includes:

[0095] S301: The backplane logic device obtains a hard disk presence signal of a hard disk device through a hard disk slot, encapsulates the hard disk presence signal into a communication receiving frame, and sends the communication receiving frame to a transmission unit.

[0096] In this embodiment, the communication reception frame at least includes a second address field and a synchronization frame header; correspondingly, the specific process of "the backplane logic device obtains the hard disk presence signal of the hard disk device through the hard disk slot" in step S301 includes:

[0098] S3012: After establishing the second communication link, complete frame synchronization through the synchronization frame header.

[0099] S3013: After completing frame synchronization, obtain the hard disk presence signal through the hard disk slot.

[0100] Specifically, after completing frame synchronization, obtain the hard disk presence signal by declaring the data length and the hard disk slot.

[0104] Among them, the declared data length is 1 byte, the final additional check value is 1 byte, and the hard disk presence signal is N bytes, where N represents the number of hard disks. Exemplarily, N is 8.

[0105] In addition, the detailed description of each piece of information in the complete communication control frame is shown in Table 2.

[0106] Table 2 Description of the complete communication reception frame

[0107]

[0108] S302: The transmission unit parses the communication reception frame to obtain the hard disk presence signal, determines the corresponding hard disk presence status according to the hard disk presence signal, and maps the hard disk presence status to the hardware device unit to complete the initialization of the hardware device unit.

[0109] In summary, for the lighting control method provided in this embodiment, through the backplane logic device, the hard disk presence signal of the hard disk device is obtained through the hard disk slot, the hard disk presence signal is encapsulated into a communication reception frame, and the communication reception frame is sent to the transmission unit; the transmission unit parses the communication reception frame to obtain the hard disk presence signal, determines the corresponding hard disk presence status according to the hard disk presence signal, and maps the hard disk presence status to the hardware device unit to complete the initialization of the hardware device unit. By initializing the hardware device unit, a foundation is laid for subsequent lighting control.

[0110] It should be noted that the communication control frame and the communication reception frame are collectively referred to as the communication frame. The communication frame includes two signal lines, the data line (SDA) and the clock line (SCL). The core timing definitions are as follows: During the period when the clock line remains high, the data line changing from high level to low level represents the start signal, and changing from low level to high level represents the stop signal; data transmission is in bytes and adopts the most significant bit (MSB) first transmission mechanism. One bit of acknowledgment signal follows each byte - during the high level period of the 9th clock cycle, the data line being low represents acknowledgment (ACK), and high level represents non-acknowledgment (NACK). The I2C protocol format includes two basic communication methods, the write mode and the read mode.

[0111] Among them, the communication control frame corresponds to the write mode. In the write mode, the host sends a 7-bit slave address (the least significant bit LSB = 0 indicates a write operation). After the slave returns an ACK acknowledgment in the 9th clock cycle, the host sends data byte by byte, and each byte requires an ACK confirmation from the slave.

[0112] Among them, the communication reception frame corresponds to the read mode. In the read mode, the host sends the slave address (LSB = 1). After the slave ACKs, it starts to send data. After the host receives each byte, it maintains the transmission by sending ACK or terminates the communication by sending NACK. And the schematic diagrams of the above I2C protocol format, I2C write mode, and I2C read mode can be seen in Figure 4 the I2C protocol schematic diagram shown.

[0113] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by means of software plus a necessary general hardware platform. Of course, it can also be implemented by hardware, but in many cases, the former is a better implementation method.

[0114] The above has introduced in detail a lighting control system and a lighting control method provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
