The structure is as follows Figure 1 As shown, the DSP chip is responsible for the inverter work, and the ARM chip is responsible for the communication work. However, in actual production, the cost of purchasing ARM chips is relatively high, so the cost of the photovoltaic inverter data acquisition system is increased; in addition, if only one MPU (MicroProcessor Unit) is configured on site at the photovoltaic inverter, the source code inside the ARM chip will be modified in the prior art (the process of modifying the source code is to remove the RTOS (Real Time Operating System) system in the ARM chip and modify the system interface function of the application) and cross-compiled, and the cross-compiled instruction set is run through the MPU to realize the function of the original ARM chip. Once the source code of the original ARM chip changes, the changed source code needs to be modified and cross-compiled accordingly. The process of modifying the source code greatly wastes time and manpower, so there is an urgent need for a low-cost, low-manpower inverter data acquisition device. Summary of the invention

[0047] The core of the present invention is to provide an inverter data acquisition method, system and computer-readable storage medium. The inverter data acquisition device used in this scheme includes not only a Linux communication protocol conversion application but also an RSIC-V soft core. Because the RSIC-V soft core runs a target executable program generated by cross-compiling the source program in the physical ARM chip, the RSIC-V soft core can replace the function of the ARM chip. Therefore, there is no need to use additional ARM chips in actual production. In addition, there is no need to modify the source code of the ARM chip, and corresponding modifications must be made after the source code of the ARM chip changes, thereby greatly reducing the cost, time and manpower requirements.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Please refer to Figure 2 , Figure 2 A process flow chart of an inverter data acquisition method provided by the present invention. The inverter data acquisition method is applied to a data acquisition device pre-integrated with a Linux communication protocol conversion application and an RSIC-V soft core, the RSIC-V soft core runs a target executable program, and the target executable program is an executable program that can be recognized by the RSIC-V soft core and is generated by cross-compiling the source program in the physical ARM chip; wherein the method includes:

[0050] S11: using the RSIC-V soft core to collect the inverter data transmitted in the DSP chip of the inverter at preset intervals using the target executable program, converting the inverter data into corresponding RSIC-V format data at preset intervals, storing the RSIC-V format data in the cache area of ​​the RSIC-V soft core, and converting the RSIC-V format data into modbus format data after receiving the first data request instruction transmitted at preset intervals by the Linux communication protocol conversion application, and transmitting the modbus format data to the Linux communication protocol conversion application;

[0051] S12: converting the modbus format data into Linux format data through the Linux communication protocol conversion application, and storing the Linux format data into a buffer area of ​​the Linux communication protocol conversion application;

[0052] S13: receiving a second data request instruction transmitted by an external device through a Linux communication protocol conversion application, converting the Linux format data into target format data required by the external device after receiving the second data request instruction, and transmitting the target format data to the external device.

[0053] In the present invention, taking into account the cost required to purchase an ARM chip, modify and cross-compile the source code inside the ARM chip, and run the cross-compiled instruction set through the MPU to realize the function of the original ARM chip, and the problem of excessive time and manpower required for subsequent maintenance, this solution runs the source program inside the physical ARM chip directly into the virtual processor inside the data collector, that is, a RSIC-V soft core is constructed in the original data collector, and the RSIC-V soft core runs a target executable program, and the target executable program is an executable program that can be recognized by the RSIC-V soft core after cross-compiling the source program in the physical ARM chip, so the RSIC-V soft core has the function of a physical ARM chip. Among them, the RSIC-V soft core uses the target executable program to collect the inverter data transmitted in the DSP chip of the inverter at preset intervals, converts it into corresponding RSIC-V format data, and stores the RSIC-V format data in the cache area of ​​the RSIC-V soft core. When receiving the first data request instruction transmitted by the Linux communication protocol conversion application, the RSIC-V format data in the storage will be converted into modbus format data and transmitted to the Linux communication protocol conversion application. The Linux communication protocol conversion application will convert the received modbus format data into Linux format data and store it in its own cache area. When receiving the second data request instruction transmitted by the external device, the Linux format data will be converted into the target format data required by the external device, and the target format data will be transmitted to the external device. This solution uses the RSIC-V soft core to run the target executable program generated after cross-compiling the source program in the physical ARM chip to replace the function of the ARM chip. Therefore, there is no need to use additional ARM chips in actual production. In addition, there is no need to modify the source code of the ARM chip, and corresponding modifications are made after the source code of the ARM chip changes, thereby greatly reducing the cost, time and manpower requirements.

[0054] It should be noted that the Linux communication protocol conversion application and the RSIC-V soft core generally communicate through message queues. This application does not limit the communication method between the Linux communication protocol conversion application and the RSIC-V soft core. The specific communication method depends on actual needs.

[0055] It should also be noted that, in the prior art, a data collector and an ARM chip are provided in the inverter data acquisition device. Because the ARM chip usually runs an RTOS (Real Time Operating System) operating system, and the data collector runs a Linux operating system, the calling function process communications of the two systems are inconsistent. If the ARM chip is omitted in the existing manner, the functions in the omitted ARM chip need to be transplanted to the data collector. However, when this method is used in the later operation, once the ARM chip program changes, the acquisition program previously transplanted into the Linux operating system must also be modified synchronously. The synchronization process requires a lot of manpower costs. Therefore, a virtual processor is proposed to address this problem, that is, the original ARM chip program is directly run into the data collector, which saves the manpower costs of transplantation, debugging and later program updates. The structural diagram of the improved inverter data acquisition device is shown as follows. Figure 3 shown.

[0056] It should also be noted that RISC-V technology has been popular in recent years, and a complete ecosystem has been established, which makes it possible for ARM embedded systems to run RSIC-V soft cores. That is, using RISC-V technology, an additional RSIC-V soft core can be run in the data collector, and the RTOS firmware can be run on the RSIC-V soft core, so that the program of the original ARM chip can be directly run into the RSIC-V soft core without modification. The RSIC-V soft core then communicates with the DSP chip, and the original data collector program then communicates with the RSIC-V soft core. The data collector collects inverter data and can exchange data with mobile phone APP and servers (external devices). It can be seen that the solution provided in this application removes an ARM chip in the original inverter, and moves the original ARM chip program to the RSIC-V soft core of the data collector processor without any modification, eliminating the manpower overhead of transplantation and later program update adaptation, and ensuring high system reliability.

[0057] It should also be noted that in actual applications, the RSIC-V soft core is written in C language, and a target executable program runs inside it. The target executable program is an executable program that can be recognized by the RSIC-V soft core after cross-compiling the source program in the physical ARM chip. The RSIC-V soft core has two major functions: 1. It is used to execute RTOS firmware and uses the RSIC-V instruction set to implement processor functions such as instruction fetching, decoding, execution, memory access, and write back; 2. External communication, through the Linux message queue to achieve inter-process communication, and communicate with the DSP chip of the inverter through the serial port. The Linux operating system will start the Linux communication protocol conversion application and the RISC-V soft core. After the RISC-V soft core is started, the RTOS firmware will be loaded into the cache area of ​​the RISC-V soft core according to the preset address. This firmware is generated by the running program of the original ARM chip through cross-compilation. After the boot program of the RISC-V soft core transfers the RTOS firmware into its own cache area, it can start to execute the program. The RISC-V soft core can collect data from the DSP chip of the inverter through the serial port, and exchange data with the Linux communication protocol conversion application through the Linux message queue. At the same stage, after the original data acquisition program is running, it communicates with the RISC-V soft core program through the Linux message queue, and transmits the collected inverter data to the cloud server or the on-site mobile phone APP (external device) through the network socket. The entire inverter data collection process is as follows Figure 4 and Figure 5 shown.

[0058] The present embodiment provides an inverter data acquisition method, which is applied to a data collector that has pre-integrated a Linux communication protocol conversion application and an RSIC-V soft core, and the RSIC-V soft core runs a target executable program generated by cross-compiling a source program in a physical ARM chip; this solution only compiles the source program of the ARM chip into a target executable program by cross-compiling, and all the functions of the physical ARM chip can be completed by running the target executable program of the RSIC-V soft core, that is, collecting inverter data transmitted by the DSP chip, converting the inverter data into RSIC-V format data, storing RSIC-V format data, converting RSIC-V format data into modbus format data, and transmitting modbus format data, which greatly saves cost, time and manpower requirements.

[0059] Based on the above embodiments:

[0060] As an optional embodiment, the inverter data transmitted in the DSP chip of the inverter is collected by the RSIC-V soft core using the target executable program at preset intervals, the inverter data is converted into corresponding RSIC-V format data at preset intervals, and the RSIC-V format data is stored in the buffer area of ​​the RSIC-V soft core, and after receiving the first data request instruction transmitted by the Linux communication protocol conversion application at preset intervals, the RSIC-V format data is converted into modbus format data, and the modbus format data is transmitted to the Linux communication protocol conversion application, including:

[0061] The target executable program is loaded through the RSIC-V soft core using the preset RTOS path and instruction fetching, decoding, execution, write-back, and memory access are performed in sequence;

[0062] The processed RSIC-V soft core uses the target executable program to collect inverter data at preset intervals;

[0063] The processed RSIC-V soft core converts the inverter data into RSIC-V format data at preset intervals using the target executable program;

[0064] The processed RSIC-V soft core uses the target executable program to store RSIC-V format data into the buffer area of ​​the RSIC-V soft core;

[0065] The processed RSIC-V soft core uses the target executable program to convert RSIC-V format data into modbus format data after receiving the first data request instruction transmitted by the Linux communication protocol conversion application at a preset periodic interval, and transmits the modbus format data to the Linux communication protocol conversion application.

[0066] In the present invention, because the target executable program is running in the RSIC-V soft core, the RSIC-V soft core can be regarded as a processor. The RSIC-V soft core will go to the program storage area Nand flash to read the firmware to its own cache and execute it. This process is similar to the computer startup boot program first copying the operating system from the disk to the DDR (Double Data Rate), and then the CPU (Central Processing Unit) starts to execute the program in the DDR. Moreover, the processor is a logic and operation unit, which will perform instruction fetching, decoding, execution, write back, and memory access operations. Instruction fetching is to fetch instructions, decoding is to convert instructions into logic and operations, and then memory access is to read and write data back to the cache. Therefore, before running the program, the RSIC-V soft core needs to use the preset RTOS path to load the target executable program and perform instruction fetching, decoding, execution, write back, and memory access in sequence. After that, the initialized RSIC-V soft core can run the target executable program to perform corresponding data collection, data storage, data conversion and data transmission functions, and accurately realize the functions of the physical ARM chip.

[0067] As an optional embodiment, after receiving the first data request instruction transmitted by the Linux communication protocol conversion application program at a preset period interval, converting RSIC-V format data into modbus format data includes:

[0068] The RSIC-V soft core uses the target executable program to extract RSIC-V format data from the RSIC-V soft core's cache area after receiving the first data request instruction transmitted at a preset period interval by the Linux communication protocol conversion application, and converts the extracted RSIC-V format data into modbus format data.

[0069] In the present invention, the specific process of the RSIC-V soft core converting RSIC-V format data into modbus format data after receiving the first data request instruction transmitted by the Linux communication protocol conversion application is as follows: because the RSIC-V soft core will use the target executable program to convert the inverter data into RSIC-V format data and store it in the cache area after collecting the inverter data, the RSIC-V soft core needs to use the target executable program to extract the RSIC-V format data from the cache area of ​​the RSIC-V soft core after receiving the first data request instruction transmitted by the Linux communication protocol conversion application at preset periodic intervals, and convert the extracted RSIC-V format data into modbus format data, thereby ensuring the integrity of the solution.

[0070] As an optional embodiment, after receiving the second data request instruction, converting the Linux format data into the target format data required by the external device, and transmitting the target format data to the external device, includes:

[0071] extracting Linux format data from a buffer area of ​​the Linux communication protocol conversion application program after receiving the second data request instruction through the Linux communication protocol conversion application program;

[0072] The Linux format data is converted into the target format data required by the external device through the Linux communication protocol conversion application, and the target format data is transmitted to the external device.

[0073] In the present invention, after receiving the second data request instruction, the Linux format data is converted into the target format data required by the external device, and the specific process of transmitting the target format data to the external device is as follows: because the Linux communication protocol conversion application converts the modbus format data into Linux format data after receiving it, and stores the Linux format data in the cache area of ​​the Linux communication protocol conversion application, when the Linux communication protocol conversion application receives the second data request instruction, it is necessary to extract the Linux format data stored in the cache area of ​​the Linux communication protocol conversion application, and convert the extracted Linux format data into the target format data required by the external device, and transmit the target format data to the external device, so as to complete the entire data collection, storage, conversion and transmission process, thereby improving the reliability of the solution.

[0074] As an optional embodiment, after transmitting the target format data to the external device, the method further includes:

[0075] The corresponding prompt signal is sent to the upper computer through the Linux communication protocol conversion application, so that the upper computer sends a corresponding display prompt and / or sound prompt after receiving the prompt signal.

[0076] In the present invention, considering that the data acquisition, data conversion, data storage and data transmission processes in the inverter data acquisition system are all independently completed by the Linux communication protocol conversion application and the RSIC-V soft core, if the Linux communication protocol conversion application or the RSIC-V soft core fails, resulting in the inability to complete each process on time or to be implemented, the maintenance personnel cannot discover and perform timely maintenance in time, so this solution, after transmitting the target format data to the external device, also sends a corresponding prompt signal to the host computer through the Linux communication protocol conversion application. If neither the Linux communication protocol conversion application nor the RSIC-V soft core fails, the host computer can receive the prompt signal at the specified time, and the host computer will give a corresponding prompt at this time; conversely, if the time when the prompt signal is received is different from the specified time or the prompt signal is not received at all, it means that the Linux communication protocol conversion application and / or the RSIC-V soft core fails at this time, and the host computer will not issue a corresponding prompt at this time. At this time, the maintenance personnel can promptly know that there is a problem with the current inverter data acquisition system and perform timely maintenance, thereby improving the safety and reliability of the solution.
