Abstract
A kind of reflection-refraction type photoelectronic position monitoring alarm, when being characterized in being mapped to people or measured object surface by the infrared ray that infrared emission tube sends, then there is Infrared to be refracted on the infrared receiving tube from the measured object surface reflection, produce photocurrent, pass through processing of circuit, can send various controls or alerting signal, monitoring distance is adjusted between from 1 millimeter to 2000 millimeters, can extensively be installed in light fixture, stationery, on toy and the furniture, monitor by distance and position, sound prompting and make the light deepening help child and teenager to read, proofread and correct posture when writing, keep good habit, eliminate myopia, phenomenons such as back of the body camel.
Description
The present invention relates to the transportation of daily necessities such as light fixture, stationery, toy and industrial traffic from the distance in controlling/monitoring and safeguard protection field and the warning device of position.
State Education Commission holds in the myopia of student eye preventing and controlling symposial, and He Dongchang the deputy director point out: the purpose of China education improves the whole nation's quality, can not educate develop more, universal more, myopia is many more.Leader of school and staff all will be paid attention to the preventing and controlling of myopia of student eye.To prevent work to myopia as the breach, promote comprehensively carrying out of school health with this.
At present, domestic and international widely used position all adopts light direct irradiation light activated element to obtain signal apart from photodetector, and this is that the light direct projection can make light activated element obtain that bigger illumination, signal are strong, processing of circuit is easy.Chinese patent CN90211785.8 " myopia prevention desk lamp " report, its shortcoming is: adopt the light direct projection to stretch out two long-armed installations and transmit and receive element, not only the complex structure cost increases, and debugging is installed inconvenient, two long-armed reader's head both sides that are placed on particularly, make the reader that constriction be arranged, very uncomfortable, therefore be difficult in the daily necessities of average family, apply.
The objective of the invention is provides a kind of reflection at the deficiencies in the prior art, the refractive photoelectronic position monitoring alarm, extensively be installed in light fixture, stationery, on the toy, in order to help child and teenager to read, proofread and correct posture when writing, keep good habit, eliminate acquired myopia, abnormal phenomenon such as back of the body camel, allow the growth of juvenile healthy, being used for when health care read-write is about 33 centimetres as sighting distance, the front is apart from the about 5-10 of table edge centimetre photoelectronic position monitoring alarm, if posture does not meet above-mentioned hygienic standard, warning device will send signal, even lamp extinguished, until recovering normal posture, could operate as normal.
Reflection provided by the invention, refractive photoelectronic position monitoring alarm are as shown in Figure 1.
