Description

Technical Field

[0001] This invention relates to a domestically produced automatic password input module for computers. Background Technology

[0002] Against the backdrop of the national promotion of the complete localization of conference room computers, domestically produced general-purpose computers will gradually become the mainstream computers used in conference rooms. Therefore, the domestically produced computers studied in this paper are domestically produced general-purpose computers. Classified conference room computers are required to have a login password set for each one. However, entering the password for each computer individually leads to reduced work efficiency due to a large amount of repetitive work, especially during frequent meetings, which also places a significant workload on meeting personnel. Therefore, there is an urgent need to research a technology that allows all conference room computers to automatically enter the password and log into the operating system with a single click. Summary of the Invention

[0004] The technical solution of the present invention: A domestically produced automatic password input module for computers includes input modules, a master controller, and slave devices. The multiple input modules are connected to a master controller and multiple slave devices respectively. The input terminal of the master controller is connected in series with the input modules connected to the slave devices via serial port relays. The multiple input modules are grounded together. The input modules simulate USB HID devices and automatically send password input commands to the computer under the action of a trigger signal.

[0005] The input module is connected to the master and slave devices via a USB interface.

[0006] The input module is connected to the serial port relay via pins.

[0007] The input module includes a microcontroller. The PA6, PA7, PA5, and PA0 pins of the microcontroller are connected to the anode of a light-emitting diode (LED) via resistors. The cathode of the LED is connected to the GND port of the USB interface. The PA2, PA3, PB1, and PC18 pins are connected to the B pin of a power-off isolator. The A pin of the power-off isolator is connected to a pin. The V+ pin of the power-off isolator and the PA9 pin of the microcontroller are connected to the VCC port of the USB interface. The V- pin of the power-off isolator and the GND pin of the microcontroller are connected to the GND port of the USB interface. The PC16 and PC17 pins of the microcontroller are connected to the D- and D+ ports of the USB interface, respectively.

[0008] The input module is in series single-trigger mode.

[0009] The input module is physically triggered via a serial port relay.

[0010] The input module is designed to be the shape of a USB flash drive.

[0011] The beneficial effects of this invention are: Based on the compatibility characteristics of the HID protocol in domestic computers, this invention integrates the HID protocol into the input module. After being connected to a domestic computer, it can be recognized by the computer as a "mouse" or "keyboard". At the same time, a physical triggering method is designed, which is triggered through a serial port relay, greatly reducing the time for staff to unlock the conference computer.

[0014] This invention provides a domestically produced automatic password input module for computers, comprising an input module, a master controller, and slave devices. The multiple input modules are respectively connected to a master controller and multiple slave devices. The input terminal of the master controller is connected in series with the input modules connected to the slave devices via serial port relays. The multiple input modules are grounded uniformly. The input modules simulate USB HID devices and automatically send password input commands to the computer under the action of a trigger signal.

[0015] The input module is connected to the master and slave devices via a USB interface.

[0016] The input module is connected to the serial port relay via pins.

[0017] The input module includes a microcontroller. The PA6, PA7, PA5, and PA0 pins of the microcontroller are connected to the anode of a light-emitting diode (LED) via resistors. The cathode of the LED is connected to the GND port of the USB interface. The PA2, PA3, PB1, and PC18 pins are connected to the B pin of a power-off isolator. The A pin of the power-off isolator is connected to a pin. The V+ pin of the power-off isolator and the PA9 pin of the microcontroller are connected to the VCC port of the USB interface. The V- pin of the power-off isolator and the GND pin of the microcontroller are connected to the GND port of the USB interface. The PC16 and PC17 pins of the microcontroller are connected to the D- and D+ ports of the USB interface, respectively.

[0018] The input module is in series single-trigger mode.

[0019] The input module is physically triggered via a serial port relay.

[0020] The input module is designed to be the shape of a USB flash drive.

[0021] Based on the characteristic that domestic computer processors can recognize and have a complete HID protocol, this invention uses a programmable and triggerable input module circuit. The input module circuit can be programmed to simulate mouse or keyboard functions. After being connected to a domestic computer, it can be recognized by the computer as a "mouse" or "keyboard". At the same time, a physical triggering method is designed, which realizes physical triggering through a serial port relay to form an automatic password input module for domestic computers. After stability testing and improvement, a stable and reliable automatic password input module is formed.

[0022] When the input module is used in the conference room, it is connected to the conference computer via a USB interface. The input modules are connected in series in a single-trigger mode. In accordance with the principle of "centralized triggering" of the automatic password input module, the application of the module in the conference room is designed in a series single-trigger connection mode, and the "ground wire" is unified to a single computer, which improves the stability and reliability of the module's execution code.

[0023] The input module is designed in the shape of a regular USB flash drive, allowing it to be used like a regular USB flash drive, but without the storage function of a USB flash drive. This design optimizes the connection between the automatic password input module and the computer motherboard, avoiding potential damage to the computer motherboard and improving connection efficiency.
