Abstract
The utility model discloses an LCD advertising machine with a function of time switch. The LCD advertising machine comprises an LCD screen, a microprocessor, a real-time clock control integrated circuit, a video play integrated circuit, and a power supply circuit. Timed on/off time is preset in system settings of the microprocessor, and then LCD advertising machine logs off a system setting interface. The LCD advertising machine can be used in the following method: when a video file with advertisements needs playing, plugging in power and normally starting to play the video file with advertisements; when a preset off time comes, the LCD screen automatically turning off and the LCD advertising machine stopping playing the video file; and when a preset boot time comes, the LCD screen lighting up and the LCD advertising machine again normally playing the video file. Therefore, the LCD advertising machine has the function of time switch, and is advantaged by simple structure and low cost, and can play advertisements at regular time.
Description
Technical field
The utility model relates to electric equipment, especially relates to a kind of liquid crystal advertiser with timed startup/shutdown function.
Background technology
Because the fast development of China's economy, people are more and more higher to the pursuit of high-quality life, and advertisement has become an indispensable part in people's life.
Advertise now and mainly contain following several mode: 1, Still Media, such as newspaper, magazine, promotional pamphlet etc.; 2, dynamic media is such as indoor tv, outdoor TV, broadcasting, scrolling billboard etc.Still Media lacks innervation owing to tone, pattern are all comparatively dull, and content is single again, is difficult to satisfy people's visual demand; Although and dynamic media tone, pattern are all very abundant, picture is smooth, abundant in content, can fully satisfy people's visual demand, bring the switch of the shortcomings, particularly some outdoor televisions such as vision is saturated, brain fag, numbness also to need the artificial manipulation of switches time to people but also exist long-time continuous broadcast meeting, thereby reach the intermittently purpose of broadcast advertisement, very trouble is made troubles to the staff.
Summary of the invention
The purpose of this utility model be to provide a kind of with timed startup/shutdown function, can realize playing advertisement at fixed time, liquid crystal advertiser simple in structure, with low cost.
The purpose of this utility model is achieved in that
A kind of liquid crystal advertiser with timed startup/shutdown function, comprise LCD screen, also comprise by microprocessor, real-time clock control integration circuit, video playback integrated circuit and power circuit, the look-at-me output terminal of the look-at-me input termination real-time clock control integration circuit of microprocessor, the protocol signal end of the protocol signal termination video playback integrated circuit of real-time clock control integration circuit, the VT of video playback integrated circuit connects the video signal input terminal of LCD screen; Power circuit is comprised of regulator, wide input step-down controller and low pressure difference linear voltage regulator, regulator general+12V voltage is output+5V voltage after the DC-to-dc conversion, supply with low pressure difference linear voltage regulator, low pressure difference linear voltage regulator general+5V voltage transitions one-tenth+3.3V voltage supplying video is play integrated circuit, wide input step-down controller general+12V is output+1.2V voltage after the DC-to-dc conversion, and supplying video is play integrated circuit; The power enable end of the power enable termination regulator of microprocessor.
The utility model is comprised of LCD screen, microprocessor, real-time clock control integration circuit, video playback integrated circuit and power circuit, it be system in microprocessor arrange the inside pre-set want the switching on and shutting down time regularly after, logging off arranges the interface again.When needs are play video file with advertisement, plug in, normally start and play the video file that contains advertisement, after the unused time that is setting in advance arrived, LCD screen will be turned off automatically, and the utility model stops playing video file; After the on time that is setting in advance arrived, LCD screen will light, and the utility model is the normal play video file again.Therefore, the utlity model has with timed startup/shutdown function, can realize playing advertisement at fixed time, advantage simple in structure, with low cost.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A kind of liquid crystal advertiser with timed startup/shutdown function, by microprocessor 1(MCU PIC12F508), real-time clock control integration circuit 2(RTC PT7C4337), video playback integrated circuit 3(AML7216), LCD screen 4(TFT LCD) and power circuit 5 form, the look-at-me output terminal of the look-at-me input termination real-time clock control integration circuit 2 of microprocessor 1, the protocol signal end of the protocol signal termination video playback integrated circuit 3 of real-time clock control integration circuit 2, the VT of video playback integrated circuit 3 connects the video signal input terminal of LCD screen 4; Power circuit 5 is by regulator 6(LM2596), wide input step-down controller 8 and low pressure difference linear voltage regulator 7 form, regulator 6 general+12V voltages are output+5V voltage after the DC-to-dc conversion, supply with low pressure difference linear voltage regulator 7, low pressure difference linear voltage regulator 7 general+5V voltage transitions one-tenth+3.3V voltage supplying videos are play integrated circuit 3, wide input step-down controller 8 general+12V are output+1.2V voltage after the DC-to-dc conversion, and supplying video is play integrated circuit 3 power circuits 5 output voltage supplying videos and play integrated circuit 3; The power enable end of the power enable termination regulator 6 of microprocessor 1.
The course of work is: after the energising, video playback integrated circuit 3 by the I2C agreement serial clock input (SCL) and after real-time clock control integration circuit 2 connects, the exchange (comprising sending and receiving) that video playback integrated circuit 3 is set up data by serial data I/O (SDA) and the real-time clock control integration circuit 2 of I2C agreement, work as timing start-up, when the setting value of unused time arrives respectively, interrupt by 2 responses of real-time clock control integration circuit, microprocessor 1 receives INTA look-at-me or the INTB look-at-me of real-time clock control integration circuit 2 responses, send high-low level to the control pin that enables of regulator 6 from general input/output port (GPIO mouth), the break-make of gauge tap voltage regulator 6, thus realize timed startup/shutdown function of the present utility model.
More than be that the liquid crystal advertiser of the utility model band timed startup/shutdown function is set forth; be used for helping to understand the utility model; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
