Description
Technical field:
The utility model belongs to induction of signal field, particularly the energy-conservation measuring instrument of one.
Background technology:
Conventional instrument is generally all provided with backlight, and the people that can conveniently check meter makes a copy of instrumented data.But the backlight of these instrument is all generally long bright pattern or manual operation mode, and under long bright pattern, backlight only plays a role when checking meter, and at ordinary times without the need to using, adds energy consumption; Under manual mode, the person of checking meter is needed to increase extra work amount.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Utility model content:
The purpose of this utility model is to provide a kind of energy-conservation measuring instrument, thus overcomes above-mentioned defect of the prior art.
For achieving the above object, the utility model provides
Energy-conservation measuring instrument, comprising: data transmission unit, infrared sensor, human-induced signal's processing unit, LCD backlight control circuit, luminous intensity observation circuit, LCD contrast adjustment circuit, LCD display translation unit, electrical signal collection processing unit; Described data transmission unit is connected with LCD display translation unit, electrical signal collection processing unit respectively; Described LCD display translation unit is connected with LCD backlight control circuit, LCD contrast adjustment circuit respectively, described LCD backlight control circuit is connected with human-induced signal's processing unit, described human-induced signal's processing unit is connected with infrared sensor, and described LCD contrast adjustment circuit is connected with luminous intensity observation circuit.
Compared with prior art, the utility model has following beneficial effect:
Utilize luminous intensity observation circuit testing environment luminous intensity, in conjunction with human-induced signal's processing unit, farthest reduce the LCD backlit operation time, reduce power consumption; Utilize LCD backlight control circuit, LCD contrast adjustment circuit, linear regulation LCD brightness of backlight and LCD display comparison degree, LCD is shown and is more suitable for human visual.
Accompanying drawing illustrates:
Fig. 1 is the utility model structured flowchart;

Fig. 6 is the utility model data transmission unit circuit diagram;
Main Reference Numerals illustrates:
1-data transmission unit, 2-infrared sensor, 3-human-induced signal processing unit, 4-LCD backlight control circuit, 5-luminous intensity observation circuit, 6-LCD contrast adjustment circuit, 7-LCD display translation unit, 8-electrical signal collection processing unit.
Embodiment:
Below embodiment of the present utility model is described in detail, but is to be understood that protection range of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in figures 1 to 6, energy-conservation measuring instrument, comprising: data transmission unit 1, infrared sensor 2, human-induced signal's processing unit 3, LCD backlight control circuit 4, luminous intensity observation circuit 5, LCD contrast adjustment circuit 6, LCD display translation unit 7, electrical signal collection processing unit 8; Described data transmission unit 1 is connected with LCD display translation unit 7, electrical signal collection processing unit 8 respectively; Described LCD display translation unit 7 is connected with LCD backlight control circuit 4, LCD contrast adjustment circuit 6 respectively, described LCD backlight control circuit 4 is connected with human-induced signal's processing unit 3, described human-induced signal's processing unit 3 is connected with infrared sensor 2, and described LCD contrast adjustment circuit 6 is connected with luminous intensity observation circuit 5.
Light intensity is too little and when having people to check meter, LCD backlight control circuit 4 opens LCD backlight, start LCD display translation unit 7.Check meter there being people but in the good situation of light, only start LCD display translation unit 7, LCD backlight and close.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
