In this embodiment, there is provided a method for upgrading server power firmware, and fig. 2 is a flowchart of a method for upgrading server power firmware according to an embodiment of the present application, as shown in fig. 2, where the flowchart includes the following steps:

step S204, the firmware upgrade data is sent to a primary side control circuit in the power supply through the WiFi component;

step S206, upgrade the power firmware in the power supply based on the upgrade instruction of the primary side control circuit.

The main body of execution of the steps may be a specific processor in the terminal, the server, the terminal or the server, or a processor or a processing device that is disposed relatively independently from the terminal or the server, but is not limited thereto.

In this embodiment, the WiFi component is an electronic component integrated with a WiFi function, and the WiFi function may be added to various devices and applications, for example, a smart phone, a tablet computer, an internet of things device, and the like. The antenna in the WiFi component is connected with the server through the AP, and a firmware upgrade packet sent by the AP in the server can be received. WiFi is a wireless local area network technology based on the IEEE 802.11 standard. The basic configuration of WiFi requires at least one Access Point (AP) and one or more client users (clients). The wireless AP in the server broadcasts SSID packets once every 100ms, the packet transmission rate is 1Mbit/s, and the packet length is quite short. WiFi specifies a minimum transmission rate of 1Mbit/s to ensure that all WiFi clients receive the SSID broadcast packet, and the clients can decide whether to connect to the SSID AP. The user can set which SSID to connect to. WiFi systems open connections to clients and support roaming, which is a benefit of Wi-Fi. Since WiFi transmits signals over air, it has the same characteristics as a non-switched ethernet network.

In this embodiment, the antenna may be built in the WiFi component, or may be an antenna external to the WiFi component.

Through the steps, as the firmware upgrade data is sent by the server and received by the WiFi component, the WiFi component is arranged on a power supply of the server, and the power supply is used for supplying power to the server; the firmware upgrading data is sent to a primary side control circuit in the power supply through the WiFi component; and upgrading the power firmware in the power supply based on the upgrade instruction of the primary side control circuit. The power supply firmware can be stably updated without being interfered by signals in the server. Therefore, the problem that the power firmware is interfered by signals in the server in the related technology can be solved, and the effect of stably upgrading the power firmware is achieved.

In one exemplary embodiment, receiving firmware upgrade data sent by a server through a WiFi component includes: receiving a firmware upgrade package sent by a server through an antenna in the WiFi assembly, wherein the antenna is in signal connection with the server; processing the firmware upgrade package through a WiFi chip in the WiFi component to obtain firmware upgrade data; the firmware upgrade data is sent to the power supply via the WiFi protocol. In the present embodiment, the antenna receives the radio wave signal of the wireless network transmitted by the AP in the server, but the transmission of the radio wave signal of the wireless network is easily interfered by other signals, and is not suitable for transmitting a long signal frame. Therefore, as shown in fig. 3, the MAC will cut (Fragment) the MSDU with a long frame into a plurality of MACProtocol Data Unit, and the antenna will combine the MSDUs after receiving the MPDUs. When transmitting signals, each MPDU represents an independent signal frame, and must receive reply information of each other. However, MPDUs belonging to the same MSDU are transmitted in a dense manner one by one, and each MPDU must also receive a reply message (Stop-and-Wait flow control method), for example, the MPDU (MAC Protocol Data Unit) signal frame format of IEEE 802.11 includes:

Header (Header): as shown in fig. 4, the length is 30Bytes, and includes fields such as Control (Frame Control), address (Address 1-4), sequence Control (Sequence Control), and Duration (Duration/ID).

Entity (Frame Body): for an indefinite length of 0-2312Bytes, data or other control information may be stored in the field, which varies depending on the Frame Type (Frame Type). It should be noted that if a broadcast or multicast signal frame is not divisible, an undivided MSDU may be packaged in the signal frame entity, and the length thereof may be longer.

Check sequence (Frame Check Sequence): the length is 4Bytes, and CRC-32 check codes are used.

According to the embodiment, the firmware upgrade package is received through the antenna in the WiFi component, so that the firmware upgrade package can be quickly obtained, and signal interference in the server can be avoided.

In an exemplary embodiment, after receiving the firmware upgrade package sent by the server through the antenna in the WiFi component, the method further includes: the firmware upgrade package is converted from a wireless signal to a digital signal through a signal conversion unit in the antenna. In this embodiment, the signal received by the antenna is a wireless signal, and digital signal conversion is required, and the signal is sent to the power supply after conversion, so that reliability and compatibility of data in the transmission process are ensured.

In an exemplary embodiment, the firmware upgrade package is processed by a WiFi chip in the WiFi component to obtain firmware upgrade data, including: decompressing the firmware upgrade package through a decompression unit in the WiFi chip to obtain decompressed data; and carrying out digital decoding on the decompressed data through a decoding unit in the WiFi chip to obtain firmware upgrading data. In this embodiment, the firmware upgrade package may be processed by the device decompression unit and the decoding unit in the WiFi chip. For example, where the WiFi chip is an ESP8266 chip, the ESP8266 chip may implement processing of data through software programming. For example, as shown in fig. 5, which is an internal architecture diagram of an ESP8266 chip, the ESP8266 chip may implement encoding and compression processing of firmware upgrade data in the following manner:

base64 coding: base64 is a commonly used encoding scheme that encodes binary data into printable ASCII characters. The software program on the ESP8266 chip may use the Base64 coding algorithm to code the data to ensure the reliability and compatibility of the data during transmission.

Data compression algorithm: the software program on the ESP8266 chip may use various data compression algorithms to reduce the size of the data to save transmission bandwidth and storage space. The data compression algorithm includes ZIP, GZIP, deflate and the like. The ESP8266 chip may compress and decompress the data using an appropriate compression library or algorithm.

Custom coding and compression algorithm: custom coding and compression algorithms may also be implemented depending on the specific application requirements. The software of the ESP8266 chip needs to be programmed in detail to design and implement coding and compression algorithms appropriate for the particular data type and application scenario.

It should be noted that, the ESP8266 chip has limited computing and memory resources, so that the resource occupation and performance requirements should be balanced when selecting the coding and compression modes. In practical applications, an appropriate encoding and compression method may be selected according to specific data types, transmission requirements, and chip resource limitations.

Furthermore, if the encoding and compression requirements of the data are high, the ESP8266 chip may need to work in conjunction with other processors or devices in order to utilize more computing and storage capabilities to implement more complex encoding and compression algorithms.

Optionally, the ESP8266 chip is responsible for receiving the firmware upgrade packet, and then sends the firmware upgrade packet to the MCU/DSP of the control chip in the power supply for firmware upgrade. For example, an ESP8266 chip has the following functions:

and (3) data forwarding: the ESP8266 chip may act as a repeater or bridge, receiving data from one device and then forwarding it to another device or the internet. The ESP8266 chip is used as a data transfer node for transmitting data from one device to another device or sending the data to the cloud for storage and processing.

Data processing and analysis: the ESP8266 chip may receive raw data sent by sensors or other devices and perform data processing and analysis locally. The ESP8266 chip may process the received data, extract useful information, and then resend the processed data according to a specific algorithm or logic. The application scene is commonly used for edge calculation in the Internet of things, and data transmission quantity and delay to the cloud are reduced by performing data processing and analysis on an ESP8266 chip.

Optionally, the ESP8266 chip is a low cost, low power consumption chip that integrates WiFi functionality, with the following parameters and protocols:

the WiFi protocol supports: ESP8266 chip supports IEEE 802.11b/g/n standard, and can communicate with standard Wi-Fi network. It may connect to an existing Wi-Fi network as a Wi-Fi client or provide wireless network services as a Wi-Fi Access Point (AP).

And (3) network management: ESP8266 chips enable connection and communication with a network through Wi-Fi management protocols (e.g., TCP/IP protocol stacks). It supports network management functions such as IP address assignment (DHCP or static IP), DNS resolution, TCP and UDP connections.

And (3) data flow management: the ESP8266 chip may perform data flow management in a variety of ways.

Socket programming: the ESP8266 chip provides a Socket interface that can communicate with a remote device using TCP or UDP protocols. By establishing Socket connection, data stream can be sent and received, and management and control of data stream can be performed.

AT instruction set: ESP8266 chip supports AT instruction set, communicates with the chip through serial port. By sending specific AT instructions, the functions of connection with Wi-Fi network, data transmission, network configuration and the like can be realized. This approach is suitable for simple communication requirements but is not suitable for advanced applications and complex data flow management.

MQTT protocol: ESP8266 chips can communicate using MQTT (Message Queuing Telemetry Transport) protocol. The MQTT is a lightweight publish-subscribe messaging protocol suitable for Internet of things applications. By using the MQTT protocol, reliable communication and data flow management between devices can be achieved.

Data flow control and processing: ESP8266 chips may use a programming language (e.g., C/C++) or use the development environment of ESP8266 (e.g., arduino IDE) to manage and process data streams. By writing corresponding codes, the functions of analyzing, converting, storing, transmitting and the like of the data can be realized so as to meet the requirements of specific applications.

ESP8266 chip can realize connection and communication with WiFi network and management and processing of data stream by supporting WiFi protocol, network management and data stream management mechanism. Communication and data flow management requirements in various application scenarios can be achieved by reasonably programming and selecting appropriate protocols.

The ESP8266 chip in this embodiment is mainly used to interact with the AP in the server, and may require retransmission of the firmware upgrade package when the received data is erroneous.

In an exemplary embodiment, after the firmware upgrade package is processed by the WiFi chip in the WiFi component to obtain firmware upgrade data, the method further includes: performing error detection on the firmware upgrade data according to cyclic redundancy check through a detection unit in the WiFi chip; and processing the firmware upgrading data according to the detection result.

Optionally, before sending the firmware upgrade data to the primary side control circuit in the power supply via the WiFi component, the method further comprises: when the firmware upgrading data is determined to be abnormal from the detection result, an automatic retransmission request is sent to the server through an antenna, and the server is requested to retransmit a firmware upgrading packet; repairing firmware upgrade data by forward error correction; and requesting the server to retransmit the firmware upgrade data in a retransmission timeout mode. For example, a cyclic redundancy check (Cyclic Redundancy Check, CRC) is used to detect whether a firmware upgrade packet is erroneous during transmission. The server calculates a CRC check value of the firmware upgrade package before transmitting the firmware upgrade package, and attaches it to the end of the firmware upgrade package. After receiving the firmware upgrade package, the WiFi chip recalculates the CRC check value and compares the CRC check value with the received check value. If the two do not match, the receiver will determine that the firmware upgrade package is in error and request the server to resend. Automatic repeat request (Automatic Repeat Request, ARQ) ARQ is an error repair mechanism for requesting a server to retransmit a firmware upgrade packet when an error occurs in the firmware upgrade packet. When the WiFi chip detects a firmware upgrade package error, it sends a special ARQ message to the server requesting retransmission of the firmware upgrade package. After receiving the ARQ message, the server resends the firmware upgrade package until the WiFi chip confirms correct reception. Forward error correction (Forward Error Correction) FEC is a scheme to add redundant data at the server for error repair at the WiFi chip. The server adds redundant information in the firmware upgrade package by using an error correction code. And when the WiFi chip receives the firmware upgrade package, the redundant information is utilized to correct the firmware upgrade package, so that the error is repaired. Such as Hamming Code and convolutional Code (Convolutional Code). Retransmission timeout (Retransmission Timeout): when the server sends a firmware upgrade package, it sets a timer. If the server does not receive the acknowledgement message from the WiFi chip within a specified time, it may consider the firmware upgrade package to be lost and resend. This ensures that the server can retransmit in time even if some firmware upgrade packets are lost during transmission.

The embodiment can realize error checking and repairing of the firmware upgrading data through the mechanism, and ensures reliable transmission of the firmware upgrading data.

In one exemplary embodiment, sending firmware upgrade data to primary side control circuitry in a power supply via a WiFi component includes: compressing firmware upgrading data through a WiFi chip to obtain compressed data; determining a data transmission interface inside the WiFi assembly as an interface adapter between the WiFi assembly and a primary side control circuit; the compressed data is sent to the primary side control circuit via the interface adapter and in accordance with the WiFi protocol. In this embodiment, the interface in the interface adapter may be an SPI, SDIO interface, or I2C, UAR. After the firmware upgrading data is determined to be correct, the firmware upgrading data is sent to the power supply through the interface adapter, so that the purpose of accurately and quickly sending the data can be achieved.

In one exemplary embodiment, upgrading power firmware in a power supply based on upgrade instructions of a primary side control circuit includes: transmitting the compressed data to a primary side control circuit in the power supply; the power supply is updated based on the upgrade instructions of the primary side control circuit.

In this embodiment, updating the power supply based on the upgrade instruction of the primary side control circuit includes the following schemes:

scheme one: and under the condition that the upgrade instruction indicates to upgrade the primary side control circuit, the primary side control circuit is upgraded by using firmware upgrade data in the compressed data.

Unlike the conventional hardware I2C communication architecture (shown in fig. 7) for firmware upgrade of the power supply, the embodiment introduces a WiFi component on the power supply hardware architecture (shown in fig. 8), and receives a firmware upgrade packet through the wireless WiFi communication network. After the antenna of the WiFi component collects the complete firmware upgrade package, the WiFi chip firstly decodes and decompresses the firmware upgrade package, then performs data error checking and repairing, and transmits the firmware upgrade data to the MCU or the DSP in the power supply to perform program refreshing action after confirming no error, thus completing the firmware upgrade flow of the power supply.

In one exemplary embodiment, the antenna includes a signal conversion unit for converting the firmware upgrade package from a wireless signal to a digital signal. In this embodiment, the signal received by the antenna is a wireless signal, and digital signal conversion is required, and the signal is sent to the power supply after conversion, so that reliability and compatibility of data in the transmission process are ensured.

In one exemplary embodiment, the WiFi chip includes a decompression unit, a decoding unit, and a detection unit;

the decompression unit is used for decompressing the firmware upgrade package to obtain decompressed data;

the decoding unit is used for carrying out digital decoding on the decompressed data to obtain firmware upgrading data;

the detection unit is used for carrying out error detection on the firmware upgrade data according to the cyclic redundancy check and repairing the firmware upgrade data when the firmware upgrade data is abnormal by at least one of the following modes: sending an automatic retransmission request to a server through an antenna to request the server to retransmit a firmware upgrade package; repairing firmware upgrade data by forward error correction; and requesting the server to retransmit the firmware upgrade data in a retransmission timeout mode.

In this embodiment, the firmware upgrade package may be processed by the device decompression unit and the decoding unit in the WiFi chip. For example, where the WiFi chip is an ESP8266 chip, the ESP8266 chip may implement processing of data through software programming. For example, the ESP8266 chip may implement the encoding and compression process of firmware upgrade data in the following manner:

base64 coding: base64 is a commonly used encoding scheme that encodes binary data into printable ASCII characters. The software program on ESP8266 may use the Base64 coding algorithm to encode data to ensure the reliability and compatibility of the data during transmission.

Data compression algorithm: the software program on ESP8266 may use various data compression algorithms to reduce the size of the data to save transmission bandwidth and storage space. The data compression algorithm includes ZIP, GZIP, deflate and the like. ESP8266 may compress and decompress data using an appropriate compression library or algorithm.

Custom coding and compression algorithm: custom coding and compression algorithms may also be implemented depending on the specific application requirements. The software of ESP8266 needs to be programmed in detail to design and implement coding and compression algorithms appropriate for the particular data type and application scenario.

Note that ESP8266 has limited computational and memory resources, and thus, the resource occupation and performance requirements should be weighed when selecting the coding and compression modes. In practical applications, an appropriate encoding and compression method may be selected according to specific data types, transmission requirements, and chip resource limitations.

Furthermore, if the encoding and compression requirements of the data are high, ESP8266 may need to work in conjunction with other processors or devices in order to utilize more computing and storage capabilities to implement more complex encoding and compression algorithms.

In addition, the detection unit may detect whether the firmware upgrade packet has an error in the transmission process using a cyclic redundancy check (Cyclic Redundancy Check, CRC). The server calculates a CRC check value of the firmware upgrade package before transmitting the firmware upgrade package, and attaches it to the end of the firmware upgrade package. After receiving the firmware upgrade package, the WiFi chip recalculates the CRC check value and compares the CRC check value with the received check value. If the two do not match, the receiver will determine that the firmware upgrade package is in error and request the server to resend. Automatic repeat request (Automatic Repeat Request, ARQ) ARQ is an error repair mechanism for requesting a server to retransmit a firmware upgrade packet when an error occurs in the firmware upgrade packet. When the WiFi chip detects a firmware upgrade package error, it sends a special ARQ message to the server requesting retransmission of the firmware upgrade package. After receiving the ARQ message, the server resends the firmware upgrade package until the WiFi chip confirms correct reception. Forward error correction (Forward Error Correction) FEC is a scheme to add redundant data at the server for error repair at the WiFi chip. The server adds redundant information in the firmware upgrade package by using an error correction code. And when the WiFi chip receives the firmware upgrade package, the redundant information is utilized to correct the firmware upgrade package, so that the error is repaired. Such as Hamming Code and convolutional Code (Convolutional Code). Retransmission timeout (Retransmission Timeout): when the server sends a firmware upgrade package, it sets a timer. If the server does not receive the acknowledgement message from the WiFi chip within a specified time, it may consider the firmware upgrade package to be lost and resend. This ensures that the server can retransmit in time even if some firmware upgrade packets are lost during transmission.

In one exemplary embodiment, the WiFi component further includes a controller coupled to the WiFi chip, the controller for controlling at least one of: parameters of the WiFi chip, a data transmission protocol of the WiFi chip, a communication mode of the WiFi chip and data flow in the WiFi chip.
