The full-automatic electronic vision detector comprises a data processing device, a display device, a wireless transmitting unit and a wireless receiving unit, wherein a sighting mark library is arranged in the data processing device, the display device is connected with the data processing device, the data processing device extracts sighting marks from the sighting mark library randomly and sends the sighting marks to the display device for display, and the wireless transmitting unit is provided with direction keys matched with the sighting marks in the sighting mark library. The wireless transmitting unit and the wireless receiving unit are arranged, so that wireless signals are transmitted to the wireless receiving unit by pressing the direction keys on the wireless transmitting unit, which correspond to directions of the deemed current sighting marks, the wireless signals are sent to the data processing device, and a person to be detected can know whether his judgment is right or not through judgment of an inner comparator, so that assistance from others is not needed during detection, self-detection is achieved, meanwhile, effects of human factors on detection results are avoided, and the workload of medical staff is reduced.
Description
Technical field
This utility model relates to a kind of eyesight detecting instrument, is specifically related to a kind of full-automatic electronic eyesight detecting instrument.
Background technology
The most traditional and the most common vision checkout equipment has lamp box visual acuity chart, vision projector, comprehensive optometry instrument, the vision checkout equipment that these are traditional, its drawback is: one, the sighting target in the visual acuity chart and arrangement mode thereof are all fixed, the ordinary people is through the observation of short time, sighting target and arrangement mode thereof can be write down, have the probability of cheating; Two, need medical personnel to use indicating bar to give directions sighting target aside, the examinee feeds back to medical personnel to the sighting target opening direction of seeing, relatively judge through the medical worker again, finally draw examinee's vision value, this has brought no small workload to medical personnel, also can make mistakes unavoidably in testing process, even in order to finish the work as early as possible, survey several sighting targets less and deal with and get over, medical personnel have brought certain influence also for the accuracy of testing result to the difference of the judgment criteria that gives a test of one's eyesight.In order to solve above-mentioned drawback, the unfixed eyesight detecting instrument of sighting target and arrangement mode thereof has appearred subsequently, basic mode has two kinds, a kind of is that more converting mechanism of many different visual acuity charts and visual acuity chart is set in the lamp box visual acuity chart, at any time change visual acuity chart, can increase the difficulty of memory greatly, reduce the probability of cheating; Another kind is to select sighting target in the sighting target storehouse internally at random by data processing equipments such as computer or single-chip microcomputers, is presented in the display device, by medical personnel's judgement of match ratio aside, finally draws examinee's vision value again.Though above-mentioned vision checkout gear can reduce the probability of cheating, but without exception, still all need medical worker's participation just can finish the process that vision detects, on-the-spot medical worker's factor is to the influence of testing result, and to medical personnel's workload alleviate still do not have an improvement.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide the influence of a kind of medical worker's of avoiding factor to testing result, alleviates medical personnel's workload, can be by the single full-automatic electronic eyesight detecting instrument of finishing the vision detection of tester.
For achieving the above object, this utility model provides following technical scheme: a kind of full-automatic electronic eyesight detecting instrument, comprise data processing equipment, display device, data processing equipment inside is provided with the sighting target storehouse, described display device is connected with data processing equipment, data processing equipment extracts sighting target at random and delivers to display device and shows from the sighting target storehouse, described it is characterized in that: described detector also is provided with wireless transmitting unit and radio receiving unit, described wireless transmitting unit be provided with the sighting target storehouse in the directionkeys that is complementary of sighting target, when a certain directionkeys is pressed, described wireless transmitting unit is launched the information of this directionkeys in the mode of wireless signal, described radio receiving unit is connected with data processing equipment, described radio receiving unit is connected by USB with data processing equipment, described radio receiving unit receives the wireless signal that described wireless transmitting unit sends and delivers to data processing equipment, described data processing equipment inside also is provided with comparator, described comparator will compare the information of shown sighting target and the directionkeys that receives, and the output comparative result.
By adopting technique scheme, owing to be provided with wireless transmitting unit and radio receiving unit, described wireless transmitting unit be provided with the sighting target storehouse in the directionkeys that is complementary of sighting target, launch wireless signal by pressing directionkeys corresponding with the current sighting target direction that identifies oneself on the wireless transmitting unit to radio receiving unit, radio receiving unit is sent into data processing equipment after receiving this wireless signal, judge through internal comparator, the tester knows namely whether oneself is correct, need not other people when therefore detecting assists, realized and single oneself to have detected, avoided the influence of anthropic factor to testing result simultaneously, alleviate medical personnel's workload; And wireless signal can comprehensively receive, and transmitting-receiving is reliable, and is very easy to use.
Below in conjunction with accompanying drawing this utility model is further described.
