Description

A kind of intellectual vision measurer

Technical field

The utility model belongs to eyesight testing field, more specifically to a kind of intellectual vision measurer.

Background technique

Original vision Test Table is mostly in such a way that a people indicates people test, and low efficiency is carried out in some schools When more human bodies are examined, consuming time is long.To solve the above problems, some Intelligent eyesight detection tables are had already appeared in the prior art, than Eyesight detection is such as carried out using cell phone application, i.e., identifies the gesture of people by mobile phone camera to give a test of one's eyesight, but it is this It is detected using the eyesight of mobile phone progress medically and lack of standardization, test error is larger.To solve the above problems, spy proposes this reality With a kind of technical solution of novel intellectual vision measurer.

Utility model content

The purpose of this utility model is to provide a kind of intellectual vision measurers will according to existing vision testing method Some manual operations are replaced using intelligent operation, save artificial, raising detection efficiency.

One intellectual vision measurer of technical solutions of the utility model, including Intelligent eyesight test chart and input unit, the intelligence Visual chart includes electricity box, and E font eyesight surface plate is provided in the electricity box, is provided with survey in the E font eyesight surface plate The quasi- E word of test-object, the E font visual chart panel rear are provided with LED light, and the LED light position and quantity are and E Testing standard E word is adapted in font eyesight surface plate, single-chip microcontroller programmable controller is additionally provided in the electricity box, signal connects It receives device and loudspeaker, the LED light, signal receiver and loudspeaker passes through signal wire with single-chip microcontroller programmable controller It connects, is provided with direction selection module and signal transmitting module in the input unit.

Preferably, the input unit is appointing in direction remote controler, speech recognition sound pick-up or sighting target direction instruction blanket It is a kind of.

Preferably, the electricity box bottom is provided with bracket, and tape measure is connected on the bracket, quarter is provided on the tape measure It spends and its tape measure length is not less than five meters.

Preferably, battery, the battery and LED light, single-chip microcontroller programmable control are additionally provided in the electricity box Device, signal receiver and loudspeaker electrical connection processed.

A kind of intellectual vision measurer of technical solutions of the utility model will mainly according to existing eyesight testing principle Manual operation is changed to the self-service intelligent operation of automation, saves manpower, improves detection efficiency.

When detection, the electricity box with E font visual chart are placed, tape is then unfolded to 5 meters of long positions, tester station It stands at 5 meters of positions of electricity box, three kinds of choice direction remote controler, speech recognition sound pick-up or sighting target direction instruction blanket inputs fill It one of sets and to carry out input operation, it is tested to try that testing standard E word opening direction is passed through signal by operation input device Sending module is sent to the single-chip microcontroller programmable controller in electricity box, and single-chip microcontroller programmable controller passes through the letter that will be sended over It number is compared with the correct direction signal of this location criteria E word opening, two signals unanimously then indicate that test is correct, and two signals are not It is consistent then indicate test errors, illustrate that tester does not see, it can thus be concluded that measured's eyesight value out.

In order to which further more accurate, accurate determination is tested eyesight value, avoid once operating accidentally due to tester Mistake and lead to eyesight testing error, in single-chip microcontroller programmable controller integrate addition module, when signal fusing occur three times Eyesight value when just carrying out judging tester's eyesight value after mistake, and second of signal fusing mistake being taken to occur is to test eyesight Value, meanwhile, for further accurate measurement tester's eyesight, at least occur 4 times in the testing standard E word of same a line.

The utility model technology the utility model has the advantages that

A kind of intellectual vision measurer of technical solutions of the utility model, test mode is constant, easy to operate, is easy to implement certainly Test is helped, testing efficiency is substantially increased, is saved artificial；Electricity box can be moved arbitrarily, and test site is flexible；Colleague's testing standard E word repeatedly occurs, and test error is small, and test is accurate.

Detailed description of the invention

Fig. 1 is a kind of intellectual vision measurer structural schematic diagram of the utility model.

Specific embodiment

For convenient for those skilled in the art understand that technical solutions of the utility model, practical new to this now in conjunction with Figure of description Type technical solution is described further.

As shown in Figure 1, an intellectual vision measurer, including Intelligent eyesight test chart and input unit 10, the Intelligent eyesight test chart Including electricity box 3, it is provided with E font eyesight surface plate 8 in the electricity box 3, is provided with test in the E font eyesight surface plate 8 Standard E word, 8 rear portion of E font eyesight surface plate are provided with LED light 1,1 position of LED light and quantity with Testing standard E word is adapted in E font eyesight surface plate 8, and single-chip microcontroller programmable controller 4, letter are additionally provided in the electricity box 3 Number receiver and loudspeaker 2, the LED light 1, signal receiver and loudspeaker 2 are logical with single-chip microcontroller programmable controller 4 Signal wire connection is crossed, is provided with direction selection module and signal transmitting module in the input unit 10,3 bottom of electricity box is provided with Bracket 6 is connected with tape measure 5 on the bracket 6, and scale is provided on the tape measure 5 and its tape measure length is not less than five meters, electricity box It is additionally provided with battery 7 in 3, the battery 7 and LED light 1, single-chip microcontroller programmable controller 4, signal receiver and raises Sound device 2 is electrically connected.

Such as Fig. 1, the input unit 10 is direction remote controler 12, speech recognition sound pick-up 11 or sighting target direction instruction blanket 13 Any one of.

As shown in Figure 1, an intellectual vision measurer, when test, the beginning of LED light 1 lights one by one, and tester is by inputting LED light 1 is inputted on device 10 lights the corresponding testing standard E word opening direction in position and by signal transmitting module by signal It is sent to single-chip microcontroller programmable controller 4, single-chip microcontroller programmable controller 4 judges this testing standard by calculating and comparing E word tests correctness, if correctly, LED light 1 continues to light downwards, if mistake, the LED light 1 gone together continue by It is a to light, if there is mistake three times, judgement test and do not seen, reached its range of vision, and broadcasted by loudspeaker Eyesight value is tested out.

When tester's choice direction remote controler 12, the key up and down on direct manually actuated direction remote controler 12 is Can, if selection speech recognition sound pick-up 11, speech recognition sound pick-up 11 picks up sound, and by translation, is translated into letter It number is sent, if selection sighting target direction instruction blanket 13, directly steps on the key up and down on moving target direction instruction blanket 13 with foot ?.

Technical solutions of the utility model are exemplarily described utility model above in conjunction with attached drawing, it is clear that this is practical Novel specific implementation is not subject to the restrictions described above, as long as using the method concept and technical solution progress of the utility model Various unsubstantialities improve, or it is not improved the conception and technical scheme of utility model are directly applied into other occasions, It both is within the protection scope of the present invention.
