Description
Technical field
The present invention relates to a kind of new interface technology of computer realm, for being connected and communicate with for specification computer and external equipment.More particularly, to a kind of keyboard equipment of USB-HID agreements.
Background technology
In actual industrial process control field, keyboard is often used as MIM message input module.Such as some equipment need to be input into some machine instructions to be operated, and these equipment often have some special demands for the function of keyboard.This several years, with the popularization of the PC of a large amount of support USB, the standard interface that USB turns into PC was trend of the times [4].USB was suggested abroad in 1994, and in 1996, the USB1.0 specifications issued by USB-iF were the first design standards of all USB products；Make elaboration and expand by USB 1.0, USB1.1 specifications are published 1998；In with latter year, the USB2.0 specifications of the 3rd version are published.After having delivered USBV0.7 versions from November 11st, 1994, USB versions experienced development for many years, have developed into 3.1 versions, as the standard extension interface in 21st century computer.In recent years, keyboard has been widely used in the business automation equipments such as PC, word processor and electronic typewriter and in industrial circle as instruction input control module.Keyboard can be divided into desktop keyboard, keyboard of notebook computer, industrial computer keyboard, Speedy typer keyboard, dual control keyboard, ultra-thin keyboard, the major class of cell phone keyboard seven according to application.Past keyboard operation is the operation of a small number of professionals, and keyboard has become the common tool of ordinary people now, it is therefore desirable to keyboard is further studied from from the viewpoint of ergonomics, is allowed to that function is more perfect, more conforms to the demand of people.The operation of keyboard requires to carry out complicated and changeable treatment action in addition to standard machinery is acted, also.Commonly used in present personal computer be capacitance keyboard, this keyboard the characteristics of be that keystroke sound is small, long service life.In recent years, developing rapidly with keyboard technique, the design more hommization of keyboard, performance increasingly meets the demand of people.Such as human engineering keyboard, it separates the left and right keypad plate in common keyboard, forms certain angle, increase handguard supporting plate in the bottom of keyboard, to wrist with fulcrum, release the fatigue that wrist is vacantly caused for a long time, and the area of space bar, enter key is increased, is reduced and is beaten frequency by mistake.The appearance of this keyboard, has benefited the personnel for being engaged in a large amount of words input work, enables them with a kind of more comfortable, natural operation.
The content of the invention
Can realize temperature real-time detection it is an object of the invention to provide one kind, and a kind of USB-HID agreements with voice alarm function keyboard equipment.
The present invention is achieved by the following technical solutions：A kind of keyboard equipment of USB-HID agreements, including micro controller system, temperature detecting module, bridge circuit module, display circuit module, A/D conversion circuit modules, key circuit module, warning circuit module, power circuit block, reset circuit, it is characterised in that：The temperature that temperature-measuring module is measured is accessed by bridge circuit, amplify signal, big signal is converted to data signal feeding microcontroller by A/D conversion circuit modules, the signal transacting that microcontroller will be gathered is calculated, Current Temperatures are shown by display module, alarm module alarm is triggered during more than threshold value.
The beneficial effects of the present invention are：
Easy to use, plug and play of the invention, small volume, additionally it is possible to functionally meet some special demands.
Brief description of the drawings：
Fig. 1 is software of the invention and hardware overall development flow chart.
Fig. 2 is module structure drafting of the present invention.
Specific embodiment：
With reference to Figure of description, the invention will be further described：
Embodiment 1
A kind of keyboard equipment of USB-HID agreements, including STM32F103RBT6 minimum systematic modules, SWD download modules, USB module, LED module, keyboard input module, BOOT modules；It is characterized in that：The STM32F103RBT6 minimum systematic modules connect SWD download modules, USB module, LED module, keyboard input module, BOOT modules respectively；The matrix keyboard of the keyboard input module connection 4 × 4.
Embodiment 2
With reference to Fig. 1, Fig. 1 is software of the invention and hardware overall development figure.The development process of the special USB key disc apparatus based on STM32, main software content is tentatively drawn using STM32F103RBT6 single-chip microcomputers；Then on the basis of the function to be realized of in-depth analysis equipment, the framework of hardware platform is carried out；Each submodule required for designing device hardware platform, draws out complete schematic diagram, and the component of function admirable is selected by reasonably comparing, and carries out the making of PCB.After hardware completes, each class descriptor to STM32F103RBT6 single-chip microcomputers and usb protocol, USB command request and equipment carries out deeper drafting, designs descriptor, it is ensured that equipment can be enumerated successfully；Programmed using KeilMDK softwares and C language, determine how to realize function expected from equipment, corresponding program is write in software environment to realize the function of each module；After the completion of programming, will be debugged in download program to hardware platform by Jlink download tools, program is write in constantly modification, and Improving Equipment function is finally reached the set goal.
Embodiment 3
With reference to Fig. 2, Fig. 2 is module structure drafting of the present invention.The basic function that special USB-HID keyboard equipments based on STM32 are expected to realize is to realize some controls that the input of button essential information and direction key can be realized to PC, and LED module is needed as indicating module, intuitively to reflect some states of system.The equipment is a USB-HID equipment, main control chip selects in the market common and function admirable STM32F103RBT6 single-chip microcomputers, using J-link download tools by download program to hardware platform, so the hardware platform of the equipment mainly needs following six module：1st, STM32F103RBT6 minimum systematic modules.
