Description
Technical field
The utility model relates to one, more specifically, it relates to a kind of Quick Response Code grenade instrumentation.
Background technology
In the past, a lot of businessmans, in order to advertise, are all that the form distributed leaflets is carried out, and so can cause the waste of a large amount of paper, and receive the passerby of leaflet, mostly can arbitrarily throw out without care, impact environment.Along with the development of internet science and technology, publicized by the form of Quick Response Code barcode scanning and become main flow, gradually instead of leaflet.But, finding by inquiry, businessman is when publicity, and Quick Response Code is also carried on poster, and related personnel is also required to move around with poster, the most inconvenient.Therefore, it is necessary to for this problem, propose a kind of new scheme, to facilitate publicist to show Quick Response Code to passerby.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of Quick Response Code grenade instrumentation, it is possible to the personnel conveniently carrying out propaganda activity provide Quick Response Code to passerby.
For achieving the above object, the utility model provides following technical scheme:
A kind of Quick Response Code grenade instrumentation, the housing being provided with cingulum including both sides and the circuit module being arranged in housing；Described circuit module includes that memory module, power module, usb interface module, USB turn serial port module, processor module, key-press module and projection module；Described key-press module includes the control button being arranged at housing side, described usb interface module is arranged at the side of housing, and turn serial port module with USB and couple, described USB transit module also couples with processor module, described memory module is used for storing two-dimensional code data, described projection module includes that laser cell and projection lens, described laser cell couple with processor module；Described projection lens is arranged at surface of shell.
Further, also including that display module, described display module include being arranged at LCD screen and the LCD driving module in housing front, described LCD drives module to couple with LCD screen and processor module respectively.
Further, described power module includes that lithium battery, charging circuit and mu balanced circuit, the input of described charging circuit couple with USB interface.
Further, described power module also includes voltage detection module, for detecting the voltage of lithium battery, and when detecting that lithium battery processes low state of charge, generates a detection signal；
Described circuit module also includes that auditory tone cues module, described auditory tone cues module send prompt tone in response to described detection signal.
Further, also including that temperature detecting module, described temperature detecting module couple with processor module, to transmit temperature signal to processor module, described processor module controls display module and is shown by temperature signal.
Compared with prior art, the utility model has the advantages that: by above technical scheme, processor module can read the two-dimensional code data in memory module, and control laser module and send corresponding light, and projects on ground or metope through projection lens.Therefore, publicist has only to this device, can arbitrarily change publicity place, it is not necessary to resist huge poster.

Fig. 1 is the overall structure figure of Quick Response Code grenade instrumentation in the utility model；
Fig. 2 is the circuit module figure of Quick Response Code grenade instrumentation in the utility model；
Fig. 3 is Quick Response Code grenade instrumentation front schematic view in the utility model.
Reference: 1, housing, 2, cingulum, 3, projection lens, 4, horn mouth, 5, LCD screen, 6, control button.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
With reference to Fig. 1, a kind of Quick Response Code grenade instrumentation, the housing being provided with cingulum including both sides and the circuit module being arranged in housing.Therefore, grenade instrumentation can be worn in wrist by publicist, very convenient.
With reference to Fig. 2, circuit module includes that memory module, power module, usb interface module, USB turn serial port module, processor module, key-press module and projection module；Key-press module includes the control button being arranged at housing side, usb interface module is arranged at the side of housing, and turn serial port module with USB and couple, USB transit module also couples with processor module, memory module is used for storing two-dimensional code data, projection module includes laser cell and projection lens, and laser cell couples with processor module；Projection lens is arranged at surface of shell.Staff is before setting out, and the two-dimensional code data of product being carried out needs by USB line publicizing imports to, in memory module, store.After arriving at, pressing control button, start grenade instrumentation, processor module reads the two-dimensional code data in memory module, and controls laser module and send corresponding light, and projects on ground or metope through projection lens, very convenient.With reference to Fig. 1, this projection lens is arranged at the front of housing.
In the present embodiment, power module includes lithium battery, charging circuit and mu balanced circuit, and the input of charging circuit couples with USB interface.Therefore, can realize by USB interface to lithium cell charging.
Power module also includes voltage detection module, for detecting the voltage of lithium battery, and when detecting that lithium battery processes low state of charge, generates a detection signal；Circuit module also includes auditory tone cues module, and auditory tone cues module sends prompt tone in response to detection signal.By arrangement above, the low electric power detection to lithium battery can be realized, and carry out reminding user immediately to charge by auditory tone cues module.Accordingly, need to offer horn mouth in the front of housing, it is to avoid sound is too small.
It addition, this grenade instrumentation also includes display module, this display module includes that the LCD screen being arranged at housing front and LCD drive module, and LCD drives module to couple with LCD screen and processor module respectively.Therefore, also can realize processor and two-dimensional code data is shown by LCD screen, so that directly Quick Response Code can be shown by LCD screen to passerby when running into place when cannot project, with reference to Fig. 3.
As the further optimization to grenade instrumentation, in the present embodiment, it is also provided with temperature detecting module, this temperature detecting module couples with processor module, to transmit temperature signal to processor module, processor module controls display module and is shown by temperature signal, with reference to Fig. 3.Pass through arrangement above, it is possible to make this grenade instrumentation have temperature display function.
