Problems solved by technology

Sometimes in the face of multiple computers, duplication and omission of power on and off are very likely to occur during the normal power-on and off-button power-on and power-off process
Under the premise of more manual intervention, it is impossible to guarantee the safety of the work results

Embodiment

[0035] The present invention executes the start-up action through MCU control, and the medium is a common USB port of computer equipment. The external power supply is transmitted to the MCU control circuit embedded in the computer through the power + line in the USB extension cable. The MCU receives the signal and controls the electronic switch formed by the triode to conduct for 3-4 seconds through the I / O port (equivalent Press the power button for 3-4 seconds), after the computer is turned on, a reference point on the motherboard provides feedback to the MCU (the voltage is 0 when the power is not turned on, and the voltage becomes 5V after the power is turned on), and the MCU judges the computer according to the feedback information of the reference point. state, if the computer is turned on, the one-key power-on button will fail to start the function, and it will work normally next time after the shutdown.

[0036] The present invention can also meet the requirements of p...

Abstract

The invention discloses a multi-computer one-key starting system based on a universal USB interface. An MCU control module is connected to each computer main board; a main power switch module converts220V alternating current into 5V2A direct current and transmits current to a power supply control module, the power supply control module synchronously transmits the current to the MCU control moduleof each computer through a USB power supply line, the MCU control module judges the starting state of each computer, and if the starting state of each computer is not started, the MCU control moduleconverts 5V voltage into 3.5 V voltage. A voltage difference larger than 0.7 V is formed between a 5V voltage and a 2.8 V power supply of a computer mainboard, a switch module on the computer mainboard is activated, then the computer mainboard is activated, a computer display screen is awakened, and one-key starting of a plurality of computers is achieved. According to the invention, the militaryconfidentiality requirement is fully met, i.e., one-key startup of a plurality of computers is realized under the direct or indirect interference of non-wireless equipment, Bluetooth equipment and infrared equipment.

Description

technical field [0001] The invention relates to a system and method for one-key start-up of multiple computers based on a universal USB interface, and is especially suitable for multiple computer equipment in computer rooms of military industrial units whose Bluetooth and network card hardware devices have been removed. Inside, without direct contact with each computer device, multiple computers can be turned on through external function keys. Background technique [0002] At present, the existing method for realizing the one-key power-on function of multiple computers on the market in my country mainly comes from controlling through the Internet (ie, remote wake-up technology), bluetooth or infrared equipment. Remote wake-up technology is divided into Wake-up ON LAN (local area network boot) and Wake-up ON Modem (modem boot) two ways. Its principle mainly uses the MAC address of the network card of each machine in the local area network to identify the specified computer i...
