Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings with embodiment.
As depicted in figs. 1 and 2, a kind of Intelligent eyesight tester, including visual chart box 1 and remote controller 5, visual chart box 1
In include embedded main control unit, infrared receiving device 1, infrared dispensing device 23 and detection symbol 4；In remote controller 5
Include embedded microprocessor, on & off switch 6, directionkeys 7, infrared receiving device 28, infrared dispensing device 1 and raise one's voice
Device device 10；Embedded main control unit receives the remote control of remote controller 5 by infrared receiving device 1 and infrared dispensing device 1
Signal, the embedded microprocessor return signal in remote controller 5 by infrared dispensing device 23 and infrared receiving device 28,
Embedded main control unit connection detection symbol 4 controls it and lights display.
Detection symbol 4 can be opening multiple " E " pictographs number varied in size towards different directions, each detection symbol
It is provided with a light emitting diode after 4, according to the output signal of embedded main control unit, lights a light emitting diode at random,
Illuminate a corresponding detection symbol 4.In this case, it is judged that process is relatively simple, due to the opening direction of detection symbol 4 it is
Fix, after therefore the numbering of each light emitting diode is fixing, the output coding of directionkeys 7 and the numbering of each light emitting diode
Corresponding relation is fixing, is directly compared with the numbering of the light emitting diode lighted by output coding.
Another kind situation of the present invention, detection symbol 4 is the sphere of movements for the elephants form point battle array being made up of light emitting diode, for opening after lighting
Mouth is towards upper, lower, left, or right " E " shape.Specifically, define its six straightways to be respectively as follows:
Left vertical line: A1；Middle vertical line: A2；Right vertical line: A3；
Upper horizontal line: B1；Middle horizontal line: B2；Lower horizontal line: B3；
LED on same straightway performs same to light order.
To form opening up " E " shape, then output signal lights A1, A2, A3, B3, i.e. B1 and B2 is 0, A1, A2,
A3 and B3 is 1, and defining this state is a；
To formed downward opening " E " shape, then output signal lights A1, A2, A3, B1, i.e. B2 and B3 is 0, A1, A2,
A3 and B1 is 1, and defining this state is b；
To form opening " E " shape towards a left side, then output signal lights B1, B2, B3 and A3, i.e. A1 and A2 is 0, B1,
B2, B3 and A3 are 1, and defining this state is c；
To form opening towards right " E " shape, then output signal lights B1, B2, B3, A1, i.e. A2 and A3 is 0, B1, B2,
B3 and A1 is 1, and defining this state is d.
Further, sphere of movements for the elephants form point battle array is multiple, varies in size, but has same center, in the case of this, each " field "
Font dot matrix carries out different coding, such as, maximum is encoded to 001, secondly be 002...., then, and and " field " of maximum
In font dot matrix, opening up " E " shape state is defined as 001a, and downward opening " E " shape state is defined as 001b, with this type of
Push away.
Remote controller 5 sends the signal starting or terminating test, embedded main control unit by & off switch 6 to visual chart box 1
After receiving this signal, output signal controls lighting display or closing of detection symbol 4.
The different control signal of output in embedded main control unit, each state the most corresponding, control by controlling output
The randomness of signal, can realize lighting at random the opening direction of " E " pictograph number.
Directionkeys 7 comprises four different directions, and the microprocessor in remote controller 5 controls infrared launcher 1 and sends
Four kinds of different coding signals, infrared receiving device 1 after receiving signal by embedded main control unit by program judgement is
No consistent with controlling " E " the pictograph opening direction after detection symbol 4 is lighted.
Specifically, four kinds of different coding signals that microprocessor sends can be respectively A1, B1, A3, B3, and A1 is with embedded
Situation when A1 in main control unit state is 0, i.e. state c, " E " shape opening is towards a left side；In B1 and embedded main control unit state
Situation when B1 is 0, i.e. state a, " E " shape is opening up；Situation, i.e. shape when A3 is 0 with the A3 in embedded main control unit state
State d, " E " shape opening is towards the right side；Situation, i.e. state b when B3 in B3 and embedded main control unit state is 0, " E " shape opening court
Under.
When only microprocessor coding signal is consistent with corresponding encoded signal value in embedded main control unit state, just card
Bright correct judgment.Comparative result sends back to remote controller 5 with the form of voice signal, after the microprocessor processes in remote controller,
Play by speaker unit 10.
As shown in Figure 3 and Figure 4, user remote controller 5 starter starts test, and embedded main control unit controls vision
The E shape mark in detection symbol 4 lighted at random by table, and user selects the opening of detection symbol by the directionkeys 7 on remote controller 5
Direction, information is returned to embedded main control unit by infrared dispensing device 1, after embedded main control unit judges, passes through
Infrared dispensing device 23 on visual chart box sends result to remote controller 5, and when result is correct, speaker sends prompt tone, with
Time visual acuity chart light the arbitrarily detection symbol of next line and continue test, during result mistake, speaker sends prompt tone, the most random
That lights same a line arbitrarily detects symbol, again occurs terminating test during mistake.
