Embodiment 1

[0122] Restricted conditions: The distances measured by the five distance sensors are L1=36.8cm, L2=35.3cm, L3=36.1cm, L4=37.5cm, L5=35.8cm, a=1cm, b=3cm, c=38cm , d=200min, e=15min, T=210min, the setting threshold of brightness sensor is 150cd / m 2 , the brightness sensor detects a brightness of 80cd / m 2 ;

[0123] According to the formula:

[0124]

[0125] Calculated: L=1.08cm;

[0126] Among them, a

[0127] Wherein, the ambient brightness detected by the brightness sensor is less than a set threshold;

[0128] According to the formula:

[0129]

[0130] Calculated: L 平 =36.3cm;

[0131] Among them, L 平 <c=38cm, judging that the distance between the human eye and the display screen of the electronic device is relatively short and meets the projection conditions;

[0132] The PLC controller sends an instruction to automatically switch the content displayed on the display screen of the electronic device...

[0135] Restricted conditions: The distances measured by the five distance sensors are L1=36.8cm, L2=35.3cm, L3=36.1cm, L4=37.5cm, L5=35.8cm, a=1cm, b=3cm, c=38cm , d=200min, e=15min, T=180min, the setting threshold of brightness sensor is 150cd / m 2 , the brightness sensor detects a brightness of 80cd / m 2 ;

[0136] According to the formula:

[0137]

[0138] Calculated: L=1.08cm;

[0139] Among them, a

[0140] Wherein, the ambient brightness detected by the brightness sensor is less than a set threshold;

[0141] According to the formula:

[0142]

[0143] Calculated: L 平 =36.3cm;

[0144] Among them, L 平 <c=38cm, judging that the distance between the human eye and the display screen of the electronic device is relatively short and meets the projection conditions;

Embodiment 3

[0148] Restricted conditions: The distances measured by the five distance sensors are L1=36.8cm, L2=35.3cm, L3=36.1cm, L4=37.5cm, L5=35.8cm, a=1cm, b=3cm, c=38cm , d=200min, e=15min The setting threshold of the brightness sensor is 150cd / m 2 , the brightness sensor detects a brightness of 180cd / m 2 ;

[0149] According to the formula:

[0150]

[0151] Calculated: L=1.08cm;

[0152] Among them, a

[0153] Among them, the ambient brightness detected by the brightness sensor is greater than the set threshold, which does not meet the projection conditions, and the projection is stopped;

[0154] According to the formula:

[0155]

[0156] Calculated: L 平 =36.3cm;

[0157] Among them, L 平 <c=38cm, it is determined that the distance between the human eye and the display screen of the electronic device is relatively short, and the user is reminded to pay attention to the distance between the eye and the display...

Abstract

The invention discloses a projection triggering system and method based on electric quantity monitoring. The projection trigger system comprises a system control module, a data acquisition module, a projection module, an adjustment module and a manual module, the projection triggering system and method are scientific and reasonable, use is safe and convenient. Through a distance sensor, accordingto a formula, the distance between the human face and the display screen of the electronic equipment can be effectively calculated; when the distance is small, the distance is small, projection capable of being carried out automatically, the damage to eyes caused by long-time and short-distance use of electronic equipment by a user can be effectively prevented; eye of a user is effectively protected, time for the user to use the projection can be counted through the timer, and when the user uses the projection for a long time, in order to protect the eye of the user and prevent addiction, thePLC controls the projection to close for a period of time, reminds the user to pay attention to rest and avoids eye fatigue.

Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to a projection trigger system and method based on power monitoring. Background technique [0002] With the continuous development of society and the continuous advancement of science and technology, electronic equipment has entered every household. The use of electronic equipment is convenient for people's lives and provides fun for boring time. However, the use of electronic equipment has also brought people certain The disadvantages of using electronic equipment at close range for a long time have caused great damage to people's eyes. Therefore, people use projection to project the content of the display screen of electronic equipment onto the projection screen, which can effectively protect the user's eyes. However, there are the following problems during use. Automatic projection cannot be performed according to the user's usage situation, and selective projection cann...
