Abstract
The invention relates to a power saving device of an expressway display screen. The power saving device of the expressway display screen comprises a power saving device body, a display screen and a far infrared sensor, wherein the power saving device body is arranged on the display screen. The power saving device of the expressway display screen is characterized in that the power saving device body further comprises an analog digital converter, a single chip and a display screen circuit switch controller, wherein the analog digital converter is connected with the far infrared sensor through data lines, the on-off action of the display screen circuit switch controller is controlled through the single chip through electric wires, and the display screen circuit switch controller is connected with the display screen. According to the power saving device of the expressway display screen, when a car passes by the underneath of the display screen, display of the display screen is controlled by inductive signals of the far infrared sensor, electric energy saving is achieved, and the power saving device of the expressway display screen is low in cost, low in power consumption and convenient to install.
Description
Technical field
The present invention relates to the battery saving arrangement field of highway display screen, especially relate to a kind of battery saving arrangement with highway display screen of far-infrared sensor structure.
Background technology
It is dull that the landscape of expressway generally all can be relatively, so the display screen on the highway usually can attract passenger, driver's attention, and, having a kind of sensation of pleasing and relief pressure, the effect of publicity is relatively good.The mode that present domestic highway display screen adopts electric light to show usually not only allows the people very clear daytime, and it is clear that also can see night.But no matter on the highway whether the car process is arranged, the electric light on the display screen continues to light, and has caused a large amount of waste of energy.The far infrared battery saving arrangement that the present invention adopts can be realized the saving of electric energy.
Summary of the invention
It is a kind of with low cost that technical matters solved by the invention is to provide, the battery saving arrangement of a kind of highway display screen of saves energy.
Technical matters solved by the invention realizes by the following technical solutions:
The battery saving arrangement of highway display screen of the present invention, comprise battery saving arrangement body, display screen and far-infrared sensor, described battery saving arrangement body is located on the described display screen, it is characterized in that: described battery saving arrangement body also comprises analog to digital converter, single-chip microcomputer and display screen contactor controller, wherein, described analog to digital converter links to each other with described far-infrared sensor by data line, and described single-chip microcomputer is controlled described display screen contactor controller break-make by electric wire; Described display screen contactor controller links to each other with described display screen.
The quantity of described far-infrared sensor is two, is installed in respectively the roadside that can see two ends, display screen highway section clearly, and the quantity of described analog to digital converter also is two, is connected with described far-infrared sensor by data line respectively.
The signal of described far-infrared sensor induction is all infrared signals that reflects through the vehicle that can see two ends, display screen highway section clearly, when having the vehicle process can see the display screen highway section clearly, described far-infrared sensor receives the infrared signal that vehicle reflects and sends described analog to digital converter to, described analog to digital converter is converted into digital signal with the simulating signal that described far-infrared sensor receives, and send described single-chip microcomputer to and carry out computing, described single-chip microcomputer is according to the break-make of the described display screen contactor of the output control of computing controller, namely when having the vehicle process can see the display screen highway section clearly, described display screen contactor controller automatically connects and regularly cuts out, thereby controls the demonstration of described display screen.
Described display screen contactor controller is connected on the different pins of described single-chip microcomputer respectively with described analog to digital converter, and other of described single-chip microcomputer are not taken over pin and all connect pull down resistor, and described battery saving arrangement body is carried out protection.
The invention has the beneficial effects as follows: when vehicle being arranged through display screen when below, the demonstration of the signal controlling display screen by the far-infrared sensor induction realizes electric energy saving, and cost is low, and is low in energy consumption, easy for installation.
