An intelligent facility detection device

Abstract

The invention provides an intelligent facility detection device comprising a shell, a controller, a voice storage module, a lens turning mechanism, a liquid crystal vision test chart, a touch screen, answering buttons and a printer. The shell is provided with a left sight hole and a right sight hole; the lens turning mechanism is provided with a left eye lens mechanism and a right eye lens mechanism corresponding to the left sight hole and the right side hole respectively. The intelligent facility detection device is characterized by intelligent fully-automatic one-button operations, increases the accuracy of detection results, prevents myopia test card printing error, detection distance error, detection time error, error caused by single-eye viewing instead of double-eye viewing, operation error, counting error, and subject cooperation error, increases the detection efficiency, standardizes detection result records, provides voice interaction, improves the enthusiasm of subjects, has complete functions, can be used for both detecting and training facility, and can monitor and guarantee the training effect and improve the training efficiency.

Description

technical field [0001] The invention relates to the technical field of vision detection, in particular to an intelligent flexibility detection device. Background technique [0002] Accommodative Facility (Accommodative Facility) reflects the ability of the eye to control the accommodative state, and is an important indicator for evaluating whether the accommodative function of the eye is normal. It reflects the quality of the adjustment flexibility by detecting the number of times the human eye effectively changes the adjustment amount within one minute. The current detection method for adjusting flexibility is the Flippers Bar Method. [0003] Inspection tools used by the double-sided mirror method include: [0004] A double-sided mirror, also known as a butterfly mirror or a flip shot, consists of a convex lens group (indicated by "+"), a concave lens group (indicated by "-"), and a connecting handle. figure 1 As shown, there are five specifications of ±1.00DS, ±1.50DS,...

AI Technical Summary

Problems solved by technology

[0013] 2. Detection distance error: The standard requires that the straight-line distance between the eyes and the near vision card during the detection process is 40cm. In actual operation, the head of the tested person will lean forward and backward, resulting in inaccurate detection results;

[0014] 3. Detection time error: The standard requires the detection of the number of flipping rings within 60S, and there will be errors ranging from a few seconds during the start and end of the actual operation timer, resulting in inaccurate detection results;

[0015] 4. Operation error: The standard requires that the double-sided mirror be flipped quickly during the detection process and placed in front of the person being tested accurately. Affected by the operator's proficiency and fatigue, it takes up too much detection time, resulting in inaccurate detection results;

[0016] 5. Counting error: The standard requires the operator to maintain communication with the tested person during the testing process to ensure that the operation is correct, and also to record the number of flipped rings, which is prone to under-recording or over-recording, resulting in inaccurate test results;

[0017] 6. Low detection efficiency: Due to the above-mentioned various reasons, the detection process is often interrupted, and more reliable detection results will appear after repeated repetitions, resulting in waste of manpower and time

[0019] 1. The training situation cannot be monitored: During the training process, most of them can only follow the subjective expression of the trainee, and the actual effect of the trainee cannot be monitored in real time;

[0020] 2. The training effect cannot be guaranteed: at the same training time, due to the above-mentioned various reasons, the training effect will vary greatly;

[0021] 3. Low training efficiency: During the training process, one staff member can only focus on one trainer, and it is impossible for one staff member to take care of several trainers at the same time

Take up a lot of human resources, the efficiency is too low
