Description

A remote switch control device

technical field

The invention relates to a remote switch machine control device.

Background technique

In the prior art, when a computer is far away from the administrator and needs to be turned on and off frequently, or the computer is placed in a relatively dangerous environment (such as strong electricity, etc.), and the computer needs to be turned on and off in time, the conventional The traditional manual boot mode is inconvenient to operate, time-consuming and labor-intensive.

Contents of the invention

In order to overcome the shortcomings of the prior art, the present invention provides a remote on/off control device, in order to quickly and effectively realize the remote on/off operation, thereby saving time and effort.

The present invention adopts following technical scheme in order to achieve the above-mentioned purpose of the invention:

The characteristics of a remote switch machine control device of the present invention include: a control terminal and a controlled terminal;

The control terminal includes: a first main control module, a first wireless transmission module, an "on" button, an "off" button, and a first USB power supply module;

The controlled terminal includes: a second main control module, a second wireless transmission module, a control module, and a second USB power supply module;

The first USB power supply module is connected to the USB port of the host computer, and is used to output the USB power supply to the first main control module and the first wireless transmission module after stepping down the voltage to 3.3V; the first main control module The interrupt pins are connected to the "on" button and the "off" button respectively, and are used to obtain button information and send a power-on command or a power-off command to the second wireless transmission module through the first wireless transmission module;

The second USB power supply module is connected to the USB port of the controlled computer host, and is used to output the USB power supply to the second main control module and the second wireless transmission module after stepping down the voltage to 3.3V; the control module and the second wireless transmission module The Pow+ pin of the controlled computer motherboard is connected with the Pow- pin, and is used to control the start-up and shutdown operations of the controlled computer host;

The second main control module is connected to the second wireless transmission module, and is used to obtain the startup instruction or shutdown instruction and control the control module to execute startup and shutdown operations of the controlled computer host.

Compared with the prior art, the beneficial effects of the present invention are reflected in:

The device of the present invention can enable people to remotely control the startup and shutdown of a host computer, and is composed of a control terminal and a controlled terminal. The USB port still supplies power after the current desktop computer is shut down, and both the main control terminal and the controlled terminal use USB power supply to supply power to the module. , the design is more convenient, the controlled terminal can be placed inside the controlled computer host, without affecting the appearance of the controlled computer, and realizes fast and effective remote switch operation.

detailed description

In this embodiment, a remote power on/off control device includes: a control terminal and a controlled terminal; the control terminal can control the startup and shutdown of the host computer connected to the controlled terminal.

As shown in Figure 1, the control terminal is configured in the sending mode, including: the first main control module, the first wireless transmission module, the "on" button, the "off" button, and the first USB power supply module; wherein, the main control module uses STM32F103RCT6 single-chip microcomputer is used as the control unit, and the wireless transmission module uses the NRF24L01 chip;

As shown in Figure 2, the controlled terminal is configured as a receiving mode, including: a second main control module, a second wireless transmission module, a control module, and a second USB power supply module;

The first USB power supply module is connected with the USB port of the host computer, and is used to output the USB power supply to the first main control module and the first wireless transmission module after stepping down the voltage to 3.3V; the interrupt pins of the first main control module are respectively connected to the first main control module The "on" button is connected with the "off" button, and is used to obtain button information and send a power-on command or a shutdown command to the second wireless transmission module through the first wireless transmission module; when the "on" button 1 is pressed, the first main control When the module is interrupted and triggered, the first main control module controls the first wireless transmission module to send a power-on command; when the "off" button 2 is pressed, the first main control module is interrupted and triggered, and the first main control module controls the first wireless instruction.

The second USB power supply module is connected with the USB port of the controlled computer host, and is used to reduce the USB power supply to 3.3V and output it to the second main control module and the second wireless transmission module; the main component of the control module is a relay, and the two relays The terminal is connected with the Pow+ pin and Pow- pin of the mainboard of the controlled computer, and is used to control the start-up and shutdown operations of the controlled computer host; when the relay is closed, Pow+ and Pow- are short-circuited, and the computer starts. When the relay is closed for more than 5s, the computer in the on state can be shut down.

The second main control module is connected with the second wireless transmission module, and is used for obtaining a start-up command or a shutdown command and controlling the control module to perform start-up and shutdown operations of the controlled computer host.

When the second main control module detects that the second wireless transmission module has received data, the second main control module reads and analyzes the data. When the data is a power-on command, the second main control module judges whether the current host is in the shutdown state through the power-on/off status flag. power on". If not, ignore this command. When the data is a shutdown command, the second main control module judges whether the current host is in the power-on state through the power-on/off status flag. If so, the second main control module controls the control module to pull in for more than 5s, shuts down the computer, and sets the power-on/off state flag as "Shut down". If not, ignore this command.
