[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0019] Embodiment 1:

[0020] See also Figures 1 to 4 The device consists of a function configuration module IC7, a core single-chip microcomputer IC1, an OLED display module IC2, a TF card holder IC3, a USB to serial port chip IC4, a USB socket J1, and a USB socket J2.

[0021] IC7 is composed of a micro lock switch, a single-chip microcomputer IC5, a FLASH memory chip IC6, and a USB socket J3. The micro lock switch is composed of a headphone plug key and a headphone jack lock. The headphone plug key is composed of four one-to-four multiple-selection switches (K1, K2, K3, K4), a push switch K5, a variable resistor R1, and a headphone plug J1. J1 has four sections of metal columns, marked as 1, 2, 3, and 4 from the top to the root. The common terminal 0 of K1 is connected to one end of K5, and the other end of K5 is connected to the common terminal 0 of K2. The common terminal 0 of K3 is connected to one end of R1, and the other end of R1 is connected to the common terminal 0 of K4. The branch ends of K1, K2, K3, and K4 are connected in sequence. Connected to the 1, 2, 3, and 4 metal columns of J1; wherein, the headphone jack lock is composed of the headphone jack J2 and the wiring terminal J3, J3 has 4 wiring terminals 1, 2, 3, and 4, and the metal hole columns of J2 are numbered 1, 2, 3, and 4 from the inside to the outside. When J1 is inserted into J2, the metal columns of J1 are connected to the metal hole columns of J2 one by one according to the serial numbers, and the metal hole columns of J2 are also connected to the wiring terminals of J3 one by one according to the serial numbers, the terminal 1 of J3 is connected to the INT1 terminal pin of the configuration microcontroller, the terminal 3 of J3 is connected to the AD1 terminal pin of the configuration microcontroller, and the terminals 2 and 4 of J3 are grounded.

[0022] It should be noted that: the other end of the four one-to-four multiple-selection switches (K1, K2, K3, K4) of the headphone plug key other than the common end cannot be connected to the same non-grounded metal column of J1, and the position of the branch switch must be determined according to the access circuit requirements of the configuration single-chip microcomputer. The positions of the K1, K2, K3, and K4 branch switches constitute a hardware access password for the headphone plug key. In this embodiment, the branch switch of K1 is in position 1, the branch switch of K2 is in position 4 (grounded), the branch switch of K3 is in position 3, and the branch switch of K4 is in position 4. Thus, the hardware access password of the headphone plug key of this embodiment is 1434.

[0023] The configuration microcontroller responds to the interrupt request generated by the closing of the K5 switch on the headphone plug key through the INT1 terminal pin. The configuration microcontroller samples the resistance value of R1 through the AD1 terminal pin in the interrupt service program. Only when the resistance value of R1 meets the characteristic value requirement can the U disk device program be run and be identified as a U disk on the operating system of the host computer (configuration party, such as: computer, smart phone, etc.), that is, the resistance value of R1 constitutes another hardware access password of the headphone plug key. In this embodiment, the resistance value of R1 is 4341 ohms. The U disk stores the configuration file of the core microcontroller. The host computer (configuration party) is connected to the configuration microcontroller through J3 and a USB cable. The user modifies the configuration file in the U disk through the host computer to set the function of the core microcontroller.

[0024] The configuration file of the core microcontroller is stored in FLASH. This FLASH storage chip is connected to the SPI1 interface of the configuration microcontroller and is also connected to the SPI2 interface of the core microcontroller. When the configuration microcontroller enters the U disk working mode, the configuration microcontroller notifies the core microcontroller through interrupt INT2 to set the SPI2 interface to high-impedance mode. When the configuration microcontroller exits the U disk working mode, the SPI1 interface of the configuration microcontroller is immediately set to high-impedance mode, and interrupt INT3 is used to notify the core microcontroller to read the configuration file in FLASH.

[0025] The USB to serial port chip is used to convert the electrical signal of the serial port 1 of the core microcontroller into a USB electrical signal.

[0026] The core single-chip microcomputer is connected to one end of the USB-to-serial port chip through serial port 1, and the other end of the USB-to-serial port chip is connected to the USB socket J2. The USB socket J2 is also connected to the lower computer (operator) through the USB Bluetooth module, and the power-specific communication protocol IEC61850-5-101 is used for communication. The core single-chip microcomputer is also connected to the target host (operator) through the USB socket J1 and the USB cable. After verifying that the digital certificate is correct, it is identified as a keyboard device and a mouse device on the operating system of the target host. The lower computer performs keyboard and mouse operations on the target host through the core single-chip microcomputer.

[0027] The OLED display module and the core microcontroller use I 2 C interface, used to display function menus, help information, real-time operation information, etc.

[0028] The TF card (socket) is connected to the core microcontroller using the SPI3 interface, and is used to read the power dispatching digital certificate for identity authentication.

[0029] The lower computer (operator) such as the intelligent robot packages the keyboard and mouse operation instructions into serial communication messages in the format of the power communication protocol, and communicates with this device using a USB cable or USB Bluetooth. This device is connected to the target host (operated party) based on the legitimate power dispatching digital certificate, and converts the keyboard and mouse operation instructions of the lower computer (operator) into corresponding keyboard and mouse operations, thereby achieving the purpose of information interaction between the lower computer (operator) and the target host (operated party).
