Abstract
A non-contact keyboard comprises an upper part plate of a platy structure. The upper part plate is located above a lower part plate of a platy structure, the lower part plate is connected with the upper part plate through a connecting piece in the vertical direction, one or more light transmitting modules are arranged on the upper part plate, each light transmitting module is provided with a photosensitive sensor module within the light transmitting range of the light transmitting module, and all the photosensitive sensor modules are arranged on the lower part plate and connected with a processor through an interface circuit. Through the structure, the defects that conditions or information needing inquiring is difficultly correctly input through an existing contact keyboard in a knocking mode in a medical environment, so that operation is inconvenient to conduct, and the normal inquiry function cannot be achieved are overcome.
Description
Technical field
The utility model belongs to medical inquiry unit technical field, is specifically related to a kind of contactless keyboard.
Background technology
?at present under medical environment, particularly under medical operating environment, often have when running into emergency need to inquire about patient CT and scheme such medical data in medical treatment or surgical procedure, owing to being all generally that what to adopt is CT to be schemed to such medical data be stored in computer system, and in the time need to inquiring about patient CT and scheme such medical data, the input equipment of computing machine knocks by means of tactile keyboard the condition or the information that need inquiry inputted often, and under medical environment, especially for surgical environments, like this because speckle with dirt on finger or have external member, thereby accurately clicking and more need the tactile keyboard being maintained in the clean condition for needs is to be difficult to adopt the mode of knocking correctly to input condition or the information of needs inquiry, thereby cause so very inconvenient operation cannot realize normal inquiry energy supply.
Summary of the invention
The purpose of this utility model provides a kind of contactless keyboard, comprise the upper board of platy structure, described upper board is positioned at the top of the lower panel of platy structure, lower panel is connected with upper board by the web member on vertical direction, on upper board, be also provided with in addition more than one light emission module, each light emission module is provided with a photosensitive sensor module in the scope of its light emission, all photosensitive sensor modules are all arranged in lower panel, and described photosensitive sensor module is connected with processor by interface circuit.Thereby such structure has avoided existing tactile keyboard in medical environment, to be difficult to adopt the mode of knocking correctly input condition or the information of needs inquiry and caused thus very inconvenient operation cannot realize the defect of normal inquiry energy supply.
In order to overcome deficiency of the prior art, the utility model provides a kind of solution of contactless keyboard, specific as follows:
A kind of contactless keyboard, comprise the upper board 1 of platy structure, described upper board 1 is positioned at the top of the lower panel 2 of platy structure, lower panel 2 is connected with upper board 1 by the web member 4 on vertical direction, on upper board 1, be also provided with in addition more than one light emission module 3, each light emission module 3 is provided with a photosensitive sensor module 5 in the scope of its light emission, all photosensitive sensor modules 5 are all arranged in lower panel 2, described photosensitive sensor module 5 is connected with processor 7 by interface circuit 6, described photosensitive sensor module 5 has also formed the button of described contactless keyboard.
Described upper board 1 and lower panel 2 are transparent material and form.
Described transparent material is organic glass.
Described light emission module 3 is light emitting diode.
Described processor 7 is CPU, PLC or ARM9 flush bonding processor.
Application the utility model such scheme, by adopting light emitting diode as light emission module 3, direct irradiation below photosensitive sensor module 5, in the time that needs carry out button, only finger need to be placed on to the corresponding photosensitive sensor module 5 of button, so just can realize the change of light intensity, the signal that corresponding photosensitive sensor module 5 changes light intensity like this sends in processor 7 by interface circuit 6, the signal that processor 7 changes according to this light intensity so is just considered as this button and is triggered, and so just can process accordingly.
Accompanying drawing explanation
Figure l is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, utility model content is described further:
Shown in Fig. 1, contactless keyboard, comprise the upper board 1 of platy structure, described upper board 1 is positioned at the top of the lower panel 2 of platy structure, lower panel 2 is connected with upper board 1 by the web member 4 on vertical direction, on upper board 1, be also provided with in addition more than one light emission module 3, each light emission module 3 is provided with a photosensitive sensor module 5 in the scope of its light emission, all photosensitive sensor modules 5 are all arranged in lower panel 2, and described photosensitive sensor module 5 is connected with processor 7 by interface circuit 6.Described upper board 1 and lower panel 2 are transparent material and form.Described transparent material is organic glass, and organic glass has high optical transmittance, physical strength height, and cracky, density are little and process advantage easily.Described light emission module 3 is light emitting diode, and the advantage of light emitting diode is energy-conservation and life cycle is long.Described processor 7 is CPU, PLC or ARM9 flush bonding processor, CPU, PLC or ARM9 flush bonding processor have cost-effective advantage, are exactly that described processor 7 and interface circuit 6 can be substituted by host computer and serial communication modular respectively in addition.
Application the utility model such scheme, its principle of work adopts light emitting diode as light emission module 3 for passing through, direct irradiation below photosensitive sensor module 5, in the time that needs carry out button, only finger need to be placed on to the corresponding photosensitive sensor module 5 of button, so just can realize the change of light intensity, the signal that corresponding photosensitive sensor module 5 changes light intensity like this sends in processor 7 by interface circuit 6, the signal that processor 7 changes according to this light intensity so is just considered as this button and is triggered, so just can process accordingly.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solutions of the utility model content, according to technical spirit of the present utility model, within spirit of the present utility model and principle, the any simple modification that above embodiment is done, be equal to replacement and improvement etc., within all still belonging to the protection domain of technical solutions of the utility model.
