Specific embodiment
Describe implementation method of the present utility model in detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of Vission detector, including visual chart box 1 and remote control 5, wrap in visual chart box 1
Contain embedded main control unit, infrared receiving device 1, infrared dispensing device 23 and detection symbols 4；Included in remote control 5
There are embedded microprocessor, on ＆ off switch 6, directionkeys 7, infrared receiving device 28, infrared dispensing device 1 and loudspeaker to fill
Put 10；Embedded main control unit receives the remote signal of remote control 5 by infrared receiving device 1 and infrared dispensing device 1,
It is embedded by infrared dispensing device 23 and infrared receiving device 28 to the embedded microprocessor return signal in remote control 5
Formula main control unit connecting detection symbol 4 controls it to light display.
Detection symbols 4 can be " E " pictograph number multiple of different sizes of opening towards different directions, each detection symbols
A light emitting diode is provided with after 4, according to the output signal of embedded main control unit, a light emitting diode is lighted at random,
Illuminate a corresponding detection symbols 4.In this case, deterministic process is relatively simple, because the opening direction of detection symbols 4 is
It is fixed, thus each light emitting diode numbering fix after, the exports coding of directionkeys 7 and the numbering of each light emitting diode
Corresponding relation is fixed, and exports coding is directly compared with the numbering of the light emitting diode lighted.
The utility model another kind situation, detection symbols 4 are the sphere of movements for the elephants form point battle array being made up of light emitting diode, after lighting
For it is opening up, under, " E " shape of left or right.Specifically, its six straightways are defined to be respectively：
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 is performed and same is lighted order.
To form opening up " E " shape, then output signal lights A1, A2, A3, B3, i.e. B1 and B2 be 0, A1, A2,
A3 and B3 is 1, defines the state for a；
To form downward opening " E " shape, then output signal lights A1, A2, A3, B1, i.e. B2 and B3 be 0, A1, A2,
A3 and B1 is 1, defines the state for b；
To form opening towards left " E " shape, then output signal lights B1, B2, B3 and A3, i.e. A1 and A2 be 0, B1,
B2, B3 and A3 are 1, define the state for c；
To form opening towards right " E " shape, then output signal lights B1, B2, B3, A1, i.e. A2 and A3 be 0, B1, B2,
B3 and A1 is 1, defines the state for d.
Further, sphere of movements for the elephants form point battle array is multiple, of different sizes, but with same center, in this case, each " field "
Font dot matrix carries out different coding, for example, maximum is encoded to 001, secondly for 002...., then, and maximum " field "
In font dot matrix, opening up " E " shape state is defined as 001a, and downward opening " E " shape state is defined as 001b, with such
Push away.
Remote control 5 sends the signal for starting or terminating test, embedded main control unit by ＆ off switch 6 to visual chart box 1
After receiving the signal, lighting for output signal control detection symbols 4 shows or closes.
Different control signals are exported in embedded main control unit, each state is corresponded to respectively, by controlled output control
The randomness of signal, is capable of achieving to light the opening direction of " E " pictograph number at random.
Directionkeys 7 includes four different directions, is sent through the microprocessor control infrared launcher 1 in remote control 5
Four kinds of different encoded signals, infrared receiving device 1 to receive after signal judged by program by embedded main control unit is
It is no consistent with " E " pictograph opening direction after controlling detection symbols 4 to light.
Specifically, four kinds of different encoded signals that microprocessor sends can be respectively A1, B1, A3, B3, A1 with it is embedded
Situation, i.e. state c when A1 in main control unit state is 0, " E " shape opening is towards a left side；In B1 and embedded main control unit state
Situation, i.e. state a when B1 is 0, " E " shape are opening up；Situation, i.e. shape when A3 in A3 and embedded main control unit state is 0
State d, " E " shape opening is towards the right side；Situation, i.e. state b, " E " shape opening court when B3 in B3 and embedded main control unit state is 0
Under.
When only microprocessor encoded signal is consistent with corresponding encoded signal value in embedded main control unit state, just demonstrate,prove
Bright correct judgment.Comparative result sends back to remote control 5 in the form of voice signal, through the microprocessor processes in remote control after,
Played by speaker unit 10.
As shown in Figure 3 and Figure 4, user starts test with the starter of remote control 5, and embedded main control unit controls eyesight
Table lights the E shape marks in detection symbols 4 at random, and user selects the opening of detection symbols by the directionkeys 7 on remote control 5
Direction, information returns to embedded main control unit by infrared dispensing device 1, after embedded main control unit is judged, passes through
Infrared dispensing device 23 on visual chart box sends result to remote control 5, and when as a result correct, loudspeaker sends prompt tone, together
When visual chart light next line any detection symbols continue test, as a result mistake when, loudspeaker sends prompt tone, while at random
Any detection symbols of same a line are lighted, occurs terminating test during mistake again.
