Abstract
The invention provides a keyboard-control-based energy-saving timing control device for a public searching machine. A microprocessor is connected with keyboard and mouse interfaces, in a PS/2 (personal system/2) specification, of the public searching machine, and is also connected with a keyboard and a mouse through the PS/2 interfaces. The microprocessor is connected with a serial port to communicate with the public searching machine. The microprocessor receives a control signal through a wireless communication module. The microprocessor is also connected with a display power supply control module. The microprocessor is also connected with an ultrasonic ranging sensor and a liquid crystal screen. If the public searching machine is not used for a long time, the microprocessor transmits a dormancy signal through the PS/2 keyboard interface to enable the public searching machine to enter a dormant state, and meanwhile, a display is switched off; if the public searching machine is used, the public searching machine is awakened through an awakening instruction, and meanwhile, power is supplied to the display. Not only is whether the public searching machine is used or not detected in real time, but also a central control signal is received to realize timed power-on and power-off.
Description
Technical field
Relate to that a kind of Catalog Search machine based on Keyboard Control is energy-conservation, time cycle controller.
Background technology
Along with the development of infotech, public place often arranges that computing machine facilitates the public to inquire about various information, generally the computing machine of this class purposes is called to the Catalog Search machine.Due to the difference of application, the utilization factor of all kinds of retrieval engines is widely different.In order to save the energy, many computing machine Energy Saving Control schemes are proposed at present, for example automatic software shutdown, control power switch Auto Power On etc.But much there are the characteristics of function singleness, wiring complexity in existing scheme.
The present invention can finely overcome the above problems, and by keyboard interface transmit button machine signal, and is furnished with wireless communication module and master controller carries out communication, installs simple.
Summary of the invention
For solving energy-conservation, the time-controlled problem of existing Catalog Search machine, the present invention designs a kind of device of controlling the Catalog Search machine by keyboard interface, and this device is installed simple, dependable performance.
The present invention is achieved through the following technical solutions:
Microprocessor is connected with keyboard, the mouse interface of the PS/2 specification of Catalog Search machine, and microprocessor also is connected with keyboard and mouse by the PS/2 interface simultaneously; Microprocessor connects serial ports and computer communication; Microprocessor is by the wireless communication module reception control signal; Micro-processing connects the monitor power supply control module simultaneously; Microprocessor connects ultrasonic distance-measuring sensor and liquid crystal display simultaneously.If long-time unmanned use of computing machine, microprocessor sends sleep signal by the PS/2 keyboard interface, makes the dormancy of Catalog Search machine, cuts off monitor power supply by the monitor power supply module simultaneously; If someone uses, wake the Catalog Search machine up by waking instruction up, recover monitor power supply simultaneously.Use the Catalog Search machine except whether detecting at any time someone, can also receive the center-control signal and realize timed power on/off.
The accompanying drawing explanation
Accompanying drawing 1 is that a kind of Catalog Search machine based on Keyboard Control is energy-conservation, the time cycle controller structural representation:
Description of reference numerals: 1, microprocessor, 2, the keyboard, the mouse interface that connect PS/2 specification on Catalog Search owner plate, 3, the socket of keyboard, mouse PS/2 specification, 4, serial port, 5, wireless communication module, 6, monitor power supply control module, 7, ultrasonic distance-measuring sensor, 8, liquid crystal display.
Concrete enforcement
Below in conjunction with accompanying drawing 1 and specific implementation method, the present invention is described in more detail.In order to purpose of the present invention, feature and advantage are carried out to more deep understanding.
A kind of Catalog Search machine based on Keyboard Control of the present invention is energy-conservation, time cycle controller, it comprises following five modules: 1, microprocessor, 2, the keyboard, the mouse interface that connect PS/2 specification on Catalog Search owner plate, 3, the socket of keyboard, mouse PS/2 specification, 4, serial port, 5, wireless communication module, 6, the monitor power supply control module, 7, ultrasonic distance-measuring sensor, 8, liquid crystal display.
A kind of Catalog Search machine based on Keyboard Control of the present invention is energy-conservation, time cycle controller, annexation between modules is: microprocessor (1) is connected with keyboard, the mouse interface (2) of the PS/2 specification of Catalog Search machine, simultaneously microprocessor (1) also the socket (3) by keyboard, mouse PS/2 specification with the keyboard and mouse of PS/2 interface commonly used in the market, be connected; Microprocessor (1) connects serial port (4) and the communication of Catalog Search machine; Microprocessor (1) is by wireless communication module (5) reception control signal; Microprocessor (1) connects monitor power supply control module (6) simultaneously; Microprocessor (1) connects ultrasonic distance-measuring sensor (7) and liquid crystal display (8) simultaneously.
The present invention is that a kind of Catalog Search machine based on Keyboard Control is energy-conservation, time cycle controller, principle of work is: if unmanned use of Catalog Search captain time, microprocessor (1) sends sleep signal by keyboard, the mouse interface (2) that connects PS/2 specification on Catalog Search owner plate, make the dormancy of Catalog Search machine, close display by controlling monitor power supply control module (6) simultaneously; If when someone uses, at first detect the approaching signal of user by ultrasonic distance-measuring sensor (7), keyboard, the mouse interface (2) of the PS/2 specification by connecting the Catalog Search machine sends and wakes instruction up and wake the Catalog Search machine up, microprocessor (1) is by the starting state of serial port (4) judgement Catalog Search, and, by connecting keyboard, mouse interface (2) sending controling instruction of PS/2 specification on Catalog Search owner plate, after having started, by control monitor power supply control module (6), give monitor power supply.In normal use procedure, microprocessor (1) obtains the instruction of user's input by the keyboard signal of socket (3) input of keyboard, mouse PS/2 specification, in microprocessor (1) decision instruction if do not contained shutdown, sleep signal, just instruction is sent to the Catalog Search machine by keyboard, the mouse interface (2) that connects PS/2 specification on Catalog Search owner plate, if contain above two kinds of special instructions, abandon this instruction.
Use Catalog Search except whether detecting at any time someone, can also receive the center-control signal and realize timed power on/off.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
