[0002] Power control and protection devices are an important part of today's power system and play a critical role in protecting the safe and stable operation of the power system. Program downloading is an indispensable process in the production process of control and protection devices. Traditional program downloading methods are mostly manual, based on the device model, to retrieve the latest program of the required device from the data source, download it to the local folder on the PC, and then manually connect the device CPU management board to the PC through a network cable. Finally, use the PC software to manually select the program in the local folder to complete the program download. This method is cumbersome and inefficient. It requires production technicians to undergo training to master the skills and methods of program downloading. This method is time-consuming, has a high risk of program download errors, and has high labor costs.

[0031] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0032] like Figure 1 As shown, the present invention provides an intelligent program downloading system for a power system control and protection device, comprising a cloud server, a fixture and at least one PC terminal, wherein the cloud server is used to obtain and store the latest program of the device from a data source; the PC terminal is used to obtain the program files required for the device from the cloud server through the TCP / IP protocol; the fixture is used to physically connect the CPU management board of the device to be downloaded to the PC terminal through a network, thereby satisfying the automatic downloading of programs for devices of different models.

[0033] In this embodiment, there can be multiple PCs, and one cloud server can correspond to multiple PCs to automatically search and download programs to devices. The same PC can also correspond to one or more devices to be downloaded. The PC is equipped with a wireless or wired barcode scanning device, which can be used to obtain the device model by scanning the barcode of the device to be downloaded, and generate a tooling handlebar insertion and retraction sequence based on the device model, and the cloud server obtains the program file applicable to the device model. Specifically, the PC parses the device model by scanning the barcode information obtained by the device to be downloaded, and retrieves the device model according to the device model name. Figure 4 The control matrix database shown is matched. If the match is successful, the S1~S16 tooling sequence corresponding to the device type in the database will be selected, and the tooling seat insertion and withdrawal sequence will be automatically generated, and the insertion and exit commands will be automatically issued to insert each tooling seat.

[0034] like Figure 5 and Figure 6 As shown, the tooling fixture includes a power board insertion and withdrawal handle seat 1 and a CPU management board insertion and withdrawal handle seat 2. The power board insertion and withdrawal handle seat 1 and the CPU management board insertion and withdrawal handle seat 2 are equipped with a two-position three-way solenoid valve and a double-axis cylinder. According to the tooling handle insertion and withdrawal sequence generated by the aforementioned PC end, the insertion and withdrawal are completed by controlling the dual-coil power supply of the solenoid valve to drive the movement of the double-axis cylinder, thereby realizing the automatic connection between the CPU management board and the PC end.

[0035] The present invention also provides a method for downloading an intelligent program of a power system control and protection device, Figure 2 As shown, the following steps are included:

[0036] Step S10, the cloud server periodically obtains newly archived program files from the company-level server, and decompresses, selects, renames, and packages the archived program files to form program files in the format required by the device to be downloaded. In order to facilitate searching, the cloud server also creates indexes for various program files downloaded from the data source.

[0037] Step S20, the PC scans the barcode of the device to be downloaded to obtain the barcode information of the device. The PC also uses the TCP / IP protocol to connect to the cloud server, and searches and obtains the required program files stored in the cloud server according to the index table or database stored in the cloud server;

[0038] In step S30, the PC end uses a wired network (including but not limited to TCP / IP protocol) to send the acquired cloud server program file to the device to be downloaded. The interactive process can be privately defined.

[0039] Step S40, the device to be downloaded receives the program file sent by the PC, decompresses it and downloads it automatically. The process information message is sent to the PC in real time so that the production technicians can understand the download progress of the device to be downloaded.

[0040] like Figure 3 As shown in the figure, as a preferred embodiment of the present invention, first, the PC scans the barcode information of the device to be downloaded, parses the device model, and retrieves the corresponding tooling sequence in the control matrix database according to the device model. The control matrix database can be used in conjunction with Figure 4 As shown, the PC searches and matches the name column of the control matrix database according to the parsed device model. If the match is successful, the tooling seat insertion and withdrawal sequence is automatically generated according to the S1~S16 tooling sequence selection corresponding to the device type in the control matrix database, and the insertion and exit command is automatically issued to insert each tooling seat, thereby inserting the power supply and the seat corresponding to the CPU management board, and physically connecting the CPU management board to the PC through the network; after the connection is successful, the PC retrieves the corresponding program file in the cloud server according to the device model name, and sends the program file to the device to be downloaded after confirmation; after the device decompresses the file, it downloads the program by itself and returns the download information message to the PC. If an error message is returned during the download process, the download process is directly exited and returns to step S20 to wait for the next code scan.

[0041] An embodiment of the present invention also provides another intelligent program downloading device for a power system control and protection device, comprising a processor and a memory configured to store a computer program that can be run on the processor; wherein, when the processor is configured to run the computer program, the method steps in the aforementioned embodiment are executed.

[0043] In practical applications, the processor includes a field programmable gate array (FPGA), and the processor may be a central processing unit (CPU) or a digital signal processor (DSP). It is understandable that for different devices, the electronic device used to implement the function of the processor may be other, and the embodiment of the present invention does not specifically limit it.
