Abstract
The utility model discloses an LCD controller of a breaker controller, comprising an infrared induction probe, an infrared induction module and a single chip. The infrared induction probe is near the observation area of the LCD of the breaker controller; the infrared induction module is connected with the infrared induction probe and outputs a switch signal according to the infrared induction signal inducted by the infrared induction probe; the single chip is connected with the infrared induction module, receives a switch signal, is connected with the LCD and controls the LCD to be opened and closed according to the switch signal. The technical scheme of the utility model adopts the way of automobile testing for people, thus ensuring that the LCD and a liquid crystal backlight are lighted only under the condition requiring the observation, thus prolonging the service life of the liquid crystal, saving the energy source and ensuring the requirement of observation. The detecting system will not affect the normal operation of the breaker controller.
Description
Technical field
The utility model relates to breaker controller, more particularly, relates to the LCD controller of breaker controller.
Background technology
In the controller that the low-voltage electrical apparatus isolating switch uses, the past uses the LED light emitting diode as display device mostly, now progressively to using liquid crystal transition.In liquid crystal display, the major part of power consumption is a part backlight, and when isolating switch is worked, and the overwhelming majority times are unmannedly to see looking on.If liquid crystal display 24 hours every days and Chang Liang backlight, the serviceable life of device is not long, has consumed a large amount of electric energy again.Control liquid crystal display and backlight if use button to be provided with, consider actual applied environment, can bring the inconvenience in the use again.
The utility model content
The utility model aims to provide a kind of LCD controller of breaker controller that can automatic switch, to solve the above problems.
According to the utility model, a kind of LCD controller of breaker controller is provided, comprising:
The infrared induction probe, the viewing area of the LCD of close breaker controller;
The infrared induction module is connected to the infrared induction probe, according to the infrared induction signal output switch signal of infrared induction probe perception;
Single-chip microcomputer is connected to the infrared induction module, and the receiving key signal is also connected to LCD, opens or close LCD according to switching signal.
In one embodiment, single-chip microcomputer is also connected to the backlight liquid crystal display module, opens or close the backlight liquid crystal display module according to switching signal.
The technical solution of the utility model adopts the method that messenger is detected automatically, has only guaranteed under the situation that needs are observed, and just allows liquid crystal display and light LCD backlight.Both prolong liquid crystal serviceable life thereby reach, energy savings can guarantee to observe the purpose that needs again.This cover detection system does not influence the operate as normal of breaker controller.
Description of drawings
The above and other feature of the present utility model, character and advantage will become more obvious by the description below in conjunction with drawings and Examples, in the accompanying drawings, identical Reference numeral is represented identical feature all the time, wherein:
Fig. 1 has disclosed the circuit block diagram according to the LCD controller of an embodiment of the present utility model.
Embodiment
With reference to shown in Figure 1, disclosed circuit block diagram according to the LCD controller 100 of the breaker controller of an embodiment of the present utility model, comprising:
Single-chip microcomputer 106 is connected to infrared induction module 104, and the receiving key signal is also connected to LCD 108, opens or close LCD 108 according to switching signal.
In the embodiment shown in fig. 1, this single-chip microcomputer 106 is also connected to backlight liquid crystal display module 110, opens or close backlight liquid crystal display module 110 according to switching signal.
Adopt the technical solution of the utility model, as the staff during near breaker controller, infrared induction probe 102 is sensed infrared signal, export " having the people to come " signal then, infrared induction module 104 and single-chip microcomputer 106 are lighted LCD 108 and backlight liquid crystal display module 110, make the clear duty of observing breaker controller of staff.In the observation process, because human body can not be absolutely stationary, so infrared induction probe 102 can constantly receive signal, thereby constantly sends signal, keeps the illuminating state of LCD 108 and backlight liquid crystal display module 110.After the staff was gone for a season, the variation that this infrared induction probe 102 detects less than infrared signal will be extinguished LCD 108 and backlight liquid crystal display module 110 automatically.
The technical solution of the utility model adopts the method that messenger is detected automatically, has only guaranteed under the situation that needs are observed, and just allows liquid crystal display and light LCD backlight.Both prolong liquid crystal serviceable life thereby reach, energy savings can guarantee to observe the purpose that needs again.This cover detection system does not influence the operate as normal of breaker controller.
The foregoing description provides to being familiar with the person in the art and realizes or use of the present utility model; those skilled in the art can be under the situation that does not break away from invention thought of the present utility model; the foregoing description is made various modifications or variation; thereby protection domain of the present utility model do not limit by the foregoing description, and should be the maximum magnitude that meets the inventive features that claims mention.
Claims (2)
1. the LCD controller of a breaker controller is characterized in that, comprising:
The infrared induction probe, the viewing area of the LCD of close breaker controller;
The infrared induction module is connected to described infrared induction probe, according to the infrared induction signal output switch signal of infrared induction probe perception;
Single-chip microcomputer is connected to described infrared induction module, receives described switching signal, is also connected to LCD, opens or close described LCD according to switching signal.
2. the LCD controller of breaker controller as claimed in claim 1 is characterized in that, described single-chip microcomputer is also connected to the backlight liquid crystal display module, opens or close described backlight liquid crystal display module according to switching signal.
