After the main control chip records the fault data, the request information for storage is sent to the display, the display receives the request information and then sends a fault message to the main control chip, the main control chip uploads the corresponding fault data to the fault message according to the fault message, and sends the fault message read the fault data to the display, and the display receives and stores the fault data. Under the condition of not increasing hardware cost additionally, the main control chip sends fault data to the display, and the display stores the fault data, so that the energy storage converter stores more fault data through the main control chip and the display.
For example, one of the scenarios of the embodiments of the present application may be applied to the scenario shown in fig. 1. The scene comprises a main control chip 101 and a display 102, wherein the display 102 receives request information for storing fault data sent by the main control chip 101 on the energy storage converter through a peripheral interface, and the fault data is recorded by the main control chip 101.

s201: and receiving request information which is sent by the main control chip of the energy storage converter through the peripheral interface and is used for storing fault data, wherein the fault data is recorded by the main control chip.
The fault data includes analog quantity information variables, digital quantity switch information variables, internal operation process variables and fault state variables in the energy storage converter. The main control chip can obtain analog quantity information such as voltage and current of an alternating current side and the like of the energy storage converter according to an analog quantity-to-digital quantity (English: analog to digital, AD) peripheral on the chip, a transformer measuring point and a printed circuit board (English: printed Circuit Board, PCB) conditioning circuit and the like which are arranged in the PCS cabinet, and the main control chip obtains state information of an internal or external switch of the energy storage converter through a digital input signal (English: digital input) measuring point of a digital quantity of a general purpose input output port (English: general Purpose Input Ouput, GPIO) peripheral on the chip and a terminal strip in the PCS cabinet.
And recording fault data by using the residual calculation power and memory resources on the main control chip by using the main control chip on the energy storage converter, and recording the data before and after the fault when the fault occurs. As an example, the number of variables to be recorded is n, where the variables to be recorded include contents such as an analog quantity information variable, a digital quantity switch information variable, an internal process variable, and a state variable, and the length of each variable record is set to m times, the value of the total recorded data n×m cannot be greater than the remaining memory resource of the main control chip, the trigger length after the fault is set to 500 (m > =500), and the data length recorded before the fault is set to m-500.
In a possible implementation manner, the main control chip can record fault record by using the residual calculation power and memory resources on the main control chip, n variables are circulated for m times of storage in a memory area with the size of n x m by taking time T as a recording interval, when the main control chip detects that a fault occurs, the storage is continuously executed for 500 times, then the storage is stopped, at the moment, m-500 times of fault record of the n variables before the fault is recorded in the memory area, and 500 times of fault record after the fault is recorded.
The display can receive the request information for storing the fault data sent by the main control chip through the peripheral interface and the optical fiber, and the peripheral interface can be a serial communication interface (English: serial Communication Interface, SCI) peripheral interface, and certainly, the application does not specifically limit the peripheral interface, and the implementation of the embodiment of the application is not affected.
S202: and sending a first fault message for reading the fault data to the main control chip according to the request information.
And the display sends a first fault message for reading the fault data to the main control chip according to the received request information, wherein the first fault message is used for reading the fault data.
S203: and receiving a second fault message which is sent by the main control chip and comprises fault data, and storing the fault data according to the second fault message.
And the main control chip correspondingly uploads fault data for each frame according to the information of the received first fault message to obtain a second fault message with the fault data, and the display receives the second fault message with the fault data and stores the fault data according to the second fault message. As shown in table 1 below, table 1 is a schematic representation of fault messages.
TABLE 1
| First fault message | 0xAA | 0x02 | 0x03 |
| Second fault message | 0xAA | 0x02 | 0x83 |
Wherein 0xAA in the first fault message indicates what frame data is, 0xAA in the second fault message indicates that the fault data of the corresponding frame is uploaded, 0x02 of the first fault message indicates the check data length (L), 0x02 of the second fault message indicates the uploaded data length (L), 0x03 of the first fault message indicates the check data length (H), and 0x83 of the second fault message indicates the uploaded data length (H).
In one possible implementation, the display integrates and constructs a second fault message with fault data, marks a time tag, and stores the second fault message in a memory card (English: secure Digital Memory Card, SD) of the display in a comma separated value file format.
In addition, the display can also receive the characteristic data transmitted by the main control chip through the peripheral interface and the first communication protocol, and then display the characteristic data through the display. The characteristic data can be an effective value of voltage and current, can be an equipment running state and can also be a fault state sign. The peripheral interface may be a SCI interface and the first communication protocol may be a serial communication protocol MODBUS. When the characteristic data transmitted by the main control chip is a fault state mark, the display can perform data analysis on the fault state mark, and when the fault state mark changes, the fault state corresponding to the fault state mark is stored in a preset fault record. The fault state flag may be a running state of the device, or may be a fault state word, where a fault state word may be 0 or 1 to indicate whether the data is correct. The preset fault record may be a record table or a record text, and of course, the present application is not specifically limited to the preset fault record, and does not affect implementation of the embodiments of the present application.
In addition, the display can also transmit fault data to the device through the network cable and the second communication protocol so that the device can perform data analysis on the fault data. The second communication protocol may be a simple file transfer protocol (english: trivial File Transfer Protocol, TFTP), and the device may be a terminal device such as a computer, which, of course, is not limited to a specific device, and does not affect implementation of the embodiments of the present application.
