Description

Based on the video wall signal automatic switching control equipment of RTC low power dissipation design

Technical field

The utility model relates to a kind of video wall signal automatic switching control equipment, particularly a kind of video wall signal automatic switching control equipment based on RTC low power dissipation design.

Background technology

Video wall is by a kind of superlarge screen TV body of wall of multiple TV (rear-projection TV) unit spliced, is a kind of image, image-text displaying system.Be widely used in the fields such as safety monitoring, convention, enterprise product information display.

In prior art, the switching mode of video wall signal is mainly: by remote controlled manner such as RS-232/LAN in given time, sends corresponding instruction.There is following defect in this technical scheme: can not ensure ageing; Artificial setting instruction is had easily to make mistakes.

Summary of the invention

The purpose of this utility model is to provide a kind of video wall signal automatic switching control equipment based on RTC low power dissipation design, and this device can be user-friendly, guarantees real-time and the accuracy of information displaying.

The utility model realizes by the following technical solutions: based on the video wall signal automatic switching control equipment of RTC low power dissipation design, it is characterized in that: RTC supply module, RTC clock module, IR shake control receiver module, micro controller module, EEPROM data storage, input signal handover module, portrait signal processing module and display screen; First of described micro controller module exports the input connecing input signal handover module; Second of described micro controller module exports the first input connecing portrait signal processing module; First input of described micro controller module connects EEPROM data storage; Second input of described micro controller module connects the output that IR shakes control receiver module; 3rd input of described micro controller module connects the output of RTC clock module; The output of described signal switching module connects an output of micro controller module; Second input of described portrait signal processing module connects another output of input signal handover module; The output of described portrait signal processing module connects the input of display screen; Described RTC supply module is powered to described RTC clock module.

In the utility model one embodiment, described RTC supply module is built-in lithium battery.

In another embodiment of the utility model, described RTC supply module is Farad capacitors.

This practical information provides video wall signal automatic switching control equipment to have the following advantages: count with RTC clock, guarantees the real-time that video wall signal is changed and accuracy; Be user-friendly to, user only need use IR remote control equipment to get final product Reusability to video wall signal switching instruction setting when first use; In this practical specific embodiment, RTC clock carries out power supply long service life, low-power consumption by farad level capacitor.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

The purpose of this utility model is to provide a kind of video wall signal automatic switching control equipment based on RTC low power dissipation design, it is characterized in that: RTC supply module, RTC clock module, IR shake control receiver module, micro controller module, EEPROM data storage, input signal handover module, portrait signal processing module and display screen; First of described micro controller module exports the input connecing input signal handover module; Second of described micro controller module exports the first input connecing portrait signal processing module; First input of described micro controller module connects EEPROM data storage; Second input of described micro controller module connects the output that IR shakes control receiver module; 3rd input of described micro controller module connects the output of RTC clock module; The output of described signal switching module connects an output of micro controller module; Second input of described portrait signal processing module connects another output of input signal handover module; The output of described portrait signal processing module connects the input of display screen; Described RTC supply module is powered to described RTC clock module.Concrete structure block diagram of the present invention is see Fig. 1.

In another embodiment of the utility model, described RTC supply module is Farad capacitors.Adopt farad level electric capacity, by 5V current supply circuit on mainboard, repeatedly charge more than 100,000 times, charging electricity can power more than one month for RTC clock loop at every turn.

RTC clock work module provides a reliable clock count for system, provides real-time clock signal.IR shakes control receiver module by remote controller, on display OSD picture, and setting respective signal switching mode and corresponding switching time, and by the data after setting by micro controller module, be stored in EEPROM data storage.The real-time clock that micro controller module provides for receiving RTC clock work module, and real time clock data is compared in real time with the set point in EEPROM data storage, as clock signal is consistent, then send instruction, notice input signal handover module and portrait signal processing module, carry out input signal switching.EEPROM data storage is used for depositing signal switching mode and corresponding switching time, as point certain second in some time, DVI picture is switched to HDMI picture etc.Input signal handover module switches input signal after receiving micro controller module instruction.After portrait signal processing module receives micro controller module by signal switching command, the input signal that input signal handover module sends is processed, and outputs to LCD display.Row display during the picture that portrait signal processing module sends by LCD display.

The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
