Intelligent vision detection system

Abstract

The invention provides an intelligent vision detection system. The intelligent vision detection system comprises an intelligent visual chart and an input device, the intelligent visual chart comprises a chart box, and a visual chart panel is arranged on the chart box. The visual chart panel is provided with test standard characters, the rear part of the visual chart panel is provided with LED indicating lamps, and the positions and the number of the LED indicating lamps are in one-to-one correspondence with those of the test standard characters on the visual chart panel; the meter box is also internally provided with a single-chip microcomputer programmable controller, a signal receiver and a loudspeaker. The LED indicating lamp, the signal receiver and the loudspeaker are all connected with the single-chip microcomputer programmable controller through signal lines. A direction selection module and a signal sending module are arranged in the input device; the method and the device are used for realizing intelligent operation of vision detection and improving the accuracy and efficiency of vision detection.

Description

technical field [0001] The invention relates to the technical field of vision detection, in particular to an intelligent vision detection system. Background technique [0002] At present, the traditional visual acuity testing process needs to be completed manually and accompanied by professionals, and the traditional visual acuity testing box is provided with overall lighting, which cannot provide targeted lighting for the test standard characters during visual acuity testing , it is necessary to manually instruct the testee to test the corresponding test standard words, and the test process is mainly through the instructions of the professional and the language communication between the professional and the testee, so as to realize the test process, the dependence on the professional is changed, and it is easy to appear error, and the detection efficiency is not high; [0003] Moreover, the traditional vision detection process needs to verbally inquire or retrieve historic...

[0002] At present, the traditional visual acuity testing process needs to be completed manually and accompanied by professionals, and the traditional visual acuity testing box is provided with overall lighting, which cannot provide targeted lighting for the test standard characters during visual acuity testing , it is necessary to manually instruct the testee to test the corresponding test standard words, and the test process is mainly through the instructions of the professional and the language communication between the professional and the testee, so as to realize the test process, the dependence on the professional is changed, and it is easy to appear error, and the detection efficiency is not high;

[0003] Moreover, the traditional vision detection process needs to verbally inquire or retrieve historical user information in the computer to obtain the user's historical user information, and then designate a detection plan, which leads to inefficiency and insufficient source of historical user information Reliable, which may lead to errors in historical user information, resulting in errors in the detection plan, which in turn leads to inaccurate detection results;
