Computer dedicated host linkage energy-saving plug-in board

technical field

The utility model relates to a plug-in board, in particular to an energy-saving plug-in board linked with a dedicated computer host.

Background technique

With the rapid development of science, technology and economy, the computer penetration rate in our country has been increasing year by year. The 23rd China Internet Development Statistics Report by China Internet Network Information Center shows that as of December 31, 2008, the number of Internet users in China reached 298 million, with a penetration rate of 22.6%, exceeding the global average; the number of Internet users increased by 8,800 compared with 2007 million people, with an annual growth rate of 41.9%. With the increase of Internet users, the usage of personal computers is also increasing, and the peripheral devices connected with computers are also gradually increasing and upgrading. The current usage status of the computer is: when the computer is turned on, even if the peripheral equipment does not work, it will become a standby state as the computer is turned on, which consumes a lot of power for no reason; Simply turn the remote control of the TV into standby mode and leave. In 2006, the 5th China International Power Supply Industry Exhibition (CIPSE) and China International Power Supply Technology Industry Forum (IFPST) were held, and the standby power consumption of home appliances became the focus of the industry. At the same time, with the adjustment of electricity prices in some areas, power saving has become a hot topic again, and standby will cause huge energy consumption. According to a survey conducted by the China Energy Conservation Product Certification Center, more than 3 million households need to pay 180 million yuan more each year just for standby energy consumption. If you count the standby energy consumption of enterprises and institutions, the figures are even more astonishing. According to the research and relevant information, the power consumption of small desktop computers in standby is about 12W, that of monitors is about 7W, that of speakers is about 12W, that of printers is about 6W, that of scanners is about 9.5W, that of modern routers is about 1W, and that of fax machines and telephones. Equipment, etc., these electrical equipment are in standby mode when the host is turned on, and many peripheral equipment are even on standby for 24 hours. All kinds of chargers are 1-3W in standby after fully charged. If a family adds two air conditioners with a standby energy consumption of 29 watts, the standby energy consumption caused by air conditioners, TVs, stereos, computers and drinking fountains in ordinary households can reach more than 100 watts. If the above-mentioned home appliances work 8 hours a day and stand by for 16 hours, a family will waste up to 1 to 2 kilowatt-hours of electricity in a day, and consume 300-500 kilowatt-hours of electricity throughout the year. The average standby energy consumption of various home appliances in the family is between 15-30 watts. The ones that consume the most standby power are PC hosts, rice cookers, DVDs, audio amplifiers, VCDs, VCRs, printers, chargers, and TVs. Implement orderly disconnection for the standby state of these electrical appliances, which will save a lot of electric energy. Due to the high standby energy consumption, my country's home appliance exports have suffered huge economic losses. The person in charge of the National Development and Reform Commission pointed out that standby energy consumption may become the next non-trade barrier.

Most of the boards currently used in conjunction with computers are common boards, most of which have only one power button. When the host is turned off or there is no operation on the computer for a long time, the ordinary plug-in board will not have any action, and all kinds of electrical equipment connected to the plug-in board are in a power-on state, which wastes a lot of electric energy virtually. Representative works of energy-saving plugboards currently on the market include old A smart power-saving sockets, special power-saving managers for Newman computers, timed energy-saving plugboards, etc. Very incomplete, when the host computer is started, the peripheral devices will be in the standby state, without selective start and stop, only for the computer and its peripherals, and cannot solve the problem of power consumption in standby mode of electrical appliances.

Detailed ways

Example. As shown in Figure 1 and Figure 2, it includes a main power switch 1, a host area 2, a peripheral area 3, a single-chip microcomputer 4 and a total power indicator light 5, and the single-chip microcomputer 4 is connected to the host area 2 and the peripheral area 3; 2 host jacks 7 (expandable), USB interface 8 and 6 peripheral device jacks 9 (expandable) are set in the peripheral area 3, fully compatible with 2PIN, 3PIN, flat head, round head and other plugs, USB interface 8 It is a USB2.0 jack. The number of host jacks 7 and peripheral device jacks 9 can be increased. The main power switch 1 is a manual main switching power supply, which is convenient for cutting off the total power supply of the plugboard. Functional areas can also be divided on the plugboard, and each functional area can be distinguished by color. The host jack 7 is directly connected with the computer host, and the USB interface 8 and the peripheral device jack 9 are connected with various peripheral devices of the computer. Each host jack 7 and peripheral equipment jack 9 are provided with an electromagnetic relay and a working power indicator 6, and the working power indicator 6 selects an LED low-power flashlight for use. When the host jack 7 or the peripheral equipment jack 9 are in work or standby In the state, the flash light is on, otherwise it is off, which is used to judge the normal working state of each jack. The jacks 7 of each host and the jacks 9 of each peripheral device are connected in parallel, all of which are independently powered in parallel, and a power failure of one jack does not affect the power supply of other jacks. The material used for the plug board is PC alloy engineering plastic with high flame retardancy and insulation. The glow wire burns at 850 degrees without burning, and the heat distortion temperature reaches 105 degrees. It is impact-resistant, pressure-resistant, heat-resistant, and moisture-resistant. It can also be designed with multi-purpose socket holes, which is suitable for standard plugs. The socket spacing is large, and it is suitable for larger plugs to be used at the same time. The power cord and other internal control wires are standard wires with sufficient power, and the plug-in board is designed to be fixed with half-open bolts, which is convenient for maintenance. The total rated current of the board is 16A; the power frequency is 50-60Hz. The control circuit is the minimum control circuit of the single-chip microcomputer. The single-chip microcomputer 4 adopts the 89C51 model, which has its own A/D conversion, reset circuit and protection circuit. It does not need a special A/D converter and uses the USB2.0 standard interface. The power supply is different, and the corresponding power-off equipment electromagnetic relay is selected. The upper computer software of the utility model adopts MicrosoftVisualBasic6.0 software to carry out interface and programming, realizes the following functions through software: detect the switch machine function of computer host computer, the Move attribute of mouse and the Click attribute of keyboard. When the host computer shutdown command is detected, the host jack 7 and the peripheral device jack 9 are powered off; Set the value to achieve selective on-off. For example, if you want to use a printer today, after the host computer is turned on, check the jack for plugging in the printer on the host computer software, and the printer will be in a standby state. After using the printer, set it to the unchecked state. The printer is powered off. When the main frame is powered on and is on standby for a long time, when the standby time is 60 seconds, the mouse and keyboard do not respond for 60 seconds. At this time, the upper computer software communicates with the single-chip microcomputer 4 to open the selected peripheral equipment. When the user moves the mouse or hits the keyboard, the peripheral device is powered on again. Both the single-chip microcomputer and the electromagnetic relay use low-power electrical components.

Working principle: the plugboard is connected to the 220 volt AC voltage power supply, after turning on the main power switch 1, the plugboard starts to work. The 220 volt voltage is divided into two circuits, one of which directly acts on the follow-up circuit, and one of which acts on the single-chip microcomputer 4 after being stepped down to 5 volts by a transformer. Connect the computer with the single-chip microcomputer 4 in the smart plug-in board with a USB data cable. When the computer is turned off, the upper computer software sends a signal, and the single-chip microcomputer 4 receives the signal and sends a command at the same time. The host area 2 and the peripheral area 3 perform power-off actions. When the host computer is turned on, the upper computer software works, and a pop-up window prompts the user to select the peripheral equipment that needs to be standby. Peripheral equipment work, then only need tick in the dialog box, just send instruction to single-chip microcomputer 4 after clicking OK, and single-chip microcomputer 4 implements the operation of energizing to corresponding electromagnetic relay. When the host computer is turned on and is in multiple modes such as standby, screen saver or sleep, and the computer does not operate for a long time, it means that the user has something to leave. Suppose the user selects the peripheral jack on the peripheral board software interface, and the peripheral will appear at this time. In the long-term standby state, the host computer software detects the mouse Move state and the keyboard Click state, and transmits the detected attribute values to the single-chip microcomputer. The single-chip microcomputer receives the signal and sends instructions to the peripherals at the same time. The electromagnetic relay of the peripherals will perform power-off. Operation, but the host is not powered on. When the user comes back, manually click the mouse or any key on the keyboard, the peripherals will be powered on and work immediately. The peripherals will not be disconnected until the host is shut down or the user resets the dialog box. This minimizes the standby time of peripheral devices.

The implementation of the utility model is not limited to the above-mentioned examples, and various changes made on the premise of not departing from the gist of the utility model all fall within the protection scope of the utility model.
