Description

Technical field

Background technique

The Intelligent Platform Management Interface (IPMI) is an open standard hardware management interface specification that defines a specific method for the embedded management subsystem to communicate. The IPMI communication protocol is similar to the two-wire serial bus (Inter-Integrated Circuit, I2C) communication protocol in hardware implementation. It also uses two lines of data line SDA and clock signal line SCL, plus a GND line. The I2C communication protocol is implemented according to the main read master write mode, that is, when the communication card communicates with the I2C device, the communication card is communicated as a host whether it is a read operation or a write operation. The IPMI communication protocol is different from the I2C protocol, and the IPMI communication protocol is implemented according to the main transmission and receiving method. The communication card operates as a host when transmitting data to the IPMI device. When the communication card receives data from the IPMI, the communication card needs to be changed to receive data from the slave. It is because of the master-slave switching that most of the I2C communication cards sold in the market cannot implement the master-slave switching function.

The microcontroller is configured to receive data sent by the host computer and data returned by the IPMI device, and complete interaction between the host computer and the IPMI device data. First, the microcontroller receives the data sent by the host computer, and after receiving the transmitted data, the data is verified. After confirming that the data is received correctly, the data is parsed. The valid data to be delivered is packaged and re-encoded. Second, the microprocessor itself is set to host mode and begins sending data to the IPMI device. When all data has been sent, the microcontroller sets itself to slave mode, waiting for IPMI to send data to the microcontroller. Once again, after receiving the data sent by the IPMI device, the microcontroller packages the data and adds a check code to the host computer after the package is completed.

After determining that the data is correct, the data is ready to be sent to the IPMI. In this case, the microcontroller needs to be set. In the host mode, the data is then sent to the IPMI device. After the data transmission is completed, the microcontroller needs to immediately switch itself to the slave mode to wait for the IPMI device to return data. After receiving the 0X01 command, IPMI will report its status data to the microcontroller. After receiving the data, the microcontroller will process the data and send it to the host computer. After receiving the data, the host computer will confirm the correctness of the data and parse it. The data is finally presented to the user in the most intuitive form.

FIG. 7 is a flowchart of a method for implementing IPMI device communication according to an optional embodiment of the present invention. As shown in FIG. 7, the steps of the method include:

That is to say, the process of sending the communication is: the initial state of the microcontroller is in a waiting state, and the upper computer software interaction interface provides an operator input interface. When the host computer sends data to the communication card, the communication card first checks the received data after receiving the data. If the verification fails, the communication card will discard the received frame data and return to the waiting state. After the verification is passed, the microcontroller parses the received data and sends the valid data to the IPMI device. After the data is sent, the microcontroller will immediately switch to slave mode and wait for the IPMI device to return data. After receiving the data, the microcontroller packages the microcontroller and sends it to the host computer. After the host computer receives the data, the data is parsed, and finally the real analog quantity is presented to the operator. This completes the transmission and reception of one frame of data.
