Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structural schematic diagram of lamppost returns state.
Fig. 4 is the structural schematic diagram that lamppost stretches out state.
Fig. 5 is the control principle drawing of the utility model.
Specific embodiment
As shown in Figure 1 and Figure 2, the Portable Automatic protrusion display notice board of the utility model, input unit 6 is using pivoted
Hanzi keyboard is inputted by contact pen.Have the characteristics that small in size, compact-sized.Input unit 6 passes through connection and processor
7 are connected.
Processor 7 has low work using the single-chip microcontroller product PIC16F877 (A) of U.S. Wei Xin company (Microship)
The features such as voltage, low-power consumption, strong driving capability.It is acted on: can be received the text that input unit 6 provides, be passed through algorithm, output
It executes instruction to actuator 8, actuator 8 acts, obtains thinking text to be shown.
Actuator 8 is execution circuit, is made of lamppost motion control circuit and LED lamp drive circuit two parts, every part
All be provided with horizontal drive circuit and column drive circuit, it is main complete the extending and retracting of lamppost 9, lamp cap being lighted and closing.
Display screen 2 by can light-emitting lamp post 9 form, it is evenly distributed, using LED light source, be made of, be arranged into 192 lampposts 9
8 rows 24 column, 192 lampposts, are divided into 3 parts, every part is 8 × 8, and corresponding row indicates by each lamppost position for convenience of description
For 0-7, respective column indicates 10-17,20-27,30-37.If the tenth list of the first row is shown as (0,21), the column of the third line the 20th are indicated
For (3,33).
As shown in Figure 3, Figure 4, lamppost 9 is by coil case 12, irony cylinder 14, lamp cap 11, limit point 15,13 groups of fixture wire
At.
Operating switch 4 is three position toggle switches, i.e. stretching-disconnection-retraction.
As shown in figure 5, using when shift operating switch onto " stretching " position, power supply is connected, and input unit 6 inputs text
Afterwards, processor 7 is handled, and by algorithm, output is executed instruction to actuator 8.The horizontal drive circuit of actuator 8 and column driving
Circuit work, first progress column scan, begins to turn on high level from first row, then connect each corresponding row, is low level.It connects
Row, corresponding lamppost 9 connects electronic work, lamppost coil 12 it is electric, form magnetic field, drive 14 stretch out motion of irony cylinder,
Stop after 14 tail end of irony cylinder encounters limiting device 15, completes the stretching of lamppost 9, as shown in figure 4, obtain wanting to highlight
Text.The lamppost of access failure is failure to actuate.After the duration scanning of a column, next column carries out in the same way again.
All each column are all swept to go over and be stopped later, complete corresponding text at this time and highlight on the display screen 2.
Shift operating switch 4 onto " retraction " position again, progress column scan first begins to turn on low level from first row, then
Each corresponding row is connected, is high level.The row of connection, corresponding lamppost 9 connect electronic work, and lamppost coil 12 obtains electric, formation
Magnetic field drives 14 retraction movement of irony cylinder, and after 11 tail end of lamp cap encounters the end of coil 12, stopping cannot retract again, complete
At the retraction of lamppost 9, as shown in Figure 3.The lamppost of access failure is failure to actuate.After the duration scanning of a column, next column
It carries out in the same way again.All each column are all swept to go over and be stopped later, and display screen 2 restores smooth automatically at this time.
Using finishing, operating switch 4 is shifted onto " off " position, power supply disconnects, and lamppost moves the row, column of driving circuit all
Electricity is not connect, notice board does not work.
Text is needed to shift lamp switch 10 onto "ON" position when shining, corresponding lamppost lamp cap 11 is lighted.Still with the first row
The lamp cap of 8th column illustrates that the first row is connect high level by the row driving of LED lamp drive circuit, and column drive the 8th column for lighting
Low level is connect, remaining row is connect into low level, remaining column connects high level, and lamp cap 11 is lighted in the lamppost that the first row the 8th arranges at this time.
Using finishing, lamp switch 10 is shifted onto off-position, the row, column of LED lamp drive circuit does not connect electricity, and LED light is gone out.
The above is only the preferred embodiment of the utility model, not imposes any restrictions to the utility model, all
According to any simple modification to the above embodiments of the utility model technical spirit, change and equivalent structural changes, still
Belong in the protection scope of technical solutions of the utility model.
