technical field

The utility model relates to a multi-channel simulation and monitoring device for mouse signals of a PS2 interface, which belongs to the field of computer peripheral devices.

Background technique

PS2 interface mouse is widely used in various control systems. However, there is no unified standard for these system equipment manufacturers, and the hardware platforms used are also different. The operating systems are quite different. It is very difficult to realize the interaction with other systems through the system. , It is necessary to find a way to interact with various control systems produced by different manufacturers.

Contents of the invention

The purpose of the present invention is to provide a device capable of interacting with various control systems produced by different manufacturers. Through this device, any computer can operate other control systems that do not provide system software interfaces through the mouse.

Summary of the invention: a mouse signal simulation and monitoring device based on the PS2 interface, mainly including a mouse signal simulation module, a communication module, and a mouse signal dispatching module; the communication module is wirelessly transmitted through a wifi network; The computer is connected, and the other end is connected to the remote control system or remote control equipment through the wifi network, so that the remote control system or remote control equipment can be operated by operating the mouse on the control computer.

The mouse signal simulation module is embedded with a single-chip microcomputer, and the conversion process from the RS232 serial port signal to the mouse signal is completed by the single-chip microcomputer; the control command part, the mouse command part is divided into several commands such as keystrokes and movement according to the characteristics of the manual mouse operation. Form a one-to-one correspondence relationship; the output part of the mouse signal is simulated by the single-chip computer software into a signal conforming to the PS2 protocol. After these simulated mouse signals are actually transmitted to the remote control system or remote control device, the effect is exactly the same as that of the hardware mouse. The device can simulate a mouse to respond to various control commands issued by the computer.

There is an STM32 chip in the communication module. First, the system calls the initialization function System_Initialization(void) of the STM32 chip to initialize the communication module. At the same time, USART1 is opened. Wi-Fi and STM32 are connected through USART1, and the waveform is set in the function UART_Configuration(void). Baud rate, interrupt type, etc.; then call the function SendDataToWi-Fi in the function void WI-FISetNetPara(IN unsigned char cPb, IN struct NetParaBuffer*cNetParaBuffer, IN unsigned char AckFlag) to pass the parameters to the Wi-Fi module through USART1 to realize data where cPb is the group number, AckFlag represents whether to return ACK after the configuration is successful, 1 is returned, 0 is not returned.

The mouse signal scheduling module, the received wireless data may conflict with the mouse signal of the computer when it is transmitted to the host. In order to avoid signal conflicts, before the signal is sent to the host, first detect whether the signal swing value exceeds A certain threshold value, if not, then transmit data; if it exceeds the threshold value, it means a collision occurs, and then judge the priority of the data received by wireless and the signal with the mouse, the priority is sent first, Those with lower priority wait.

Beneficial effect

1. Through the simulation and monitoring equipment based on the mouse signal of the PS2 interface, it can interact with various remote control systems or remote control equipment produced by different manufacturers. Therefore, any computer can use the mouse to operate other unavailable A remote control system or remote control device that provides a system software interface.

Detailed ways

As shown in Figures 1 to 4, a simulation and monitoring device based on PS2 interface mouse signals mainly includes a mouse signal simulation module, a communication module, and a mouse signal dispatching module; the communication module is wirelessly transmitted through a wifi network; the simulation and monitoring device One end is connected to the control computer through the signal line, and the other end is connected to the remote control system or remote control equipment through the wifi network, so that the remote control system or remote control equipment can be operated by operating the mouse on the control computer.

Since remote control systems or remote control devices generally have standard IO interfaces, the simulation and monitoring equipment based on PS2 interface mouse signals convert the standard mouse signals from the control computer into signals that these remote control systems or remote control devices can recognize , and then passed to the remote control system or remote control equipment, system interaction can be realized.

Form a one-to-one correspondence relationship; the output part of the mouse signal is simulated by the single-chip computer software into a signal conforming to the PS2 protocol. After these simulated mouse signals are actually transmitted to the remote control system or remote control device, the effect is exactly the same as that of the hardware mouse. The device can simulate a mouse to respond to various control commands issued by the computer.

There is an STM32 chip in the communication module. First, the system calls the initialization function System_Initialization(void) of the STM32 chip to initialize the communication module. At the same time, USART1 is opened. Wi-Fi and STM32 are connected through USART1, and the waveform is set in the function UART_Configuration(void).
