The embodiment of the present invention is based on the basis of sand table, in conjunction with the thought of embedded system, by constructing the control module of sand table to the design of control circuit and the method for computer programming, and itself and PC are linked combine, control sand table that can be artificial demonstrates the landform or image wanted, is referred to as digital sand table.
The embodiment of the present invention devises the mechanical hook-up of 3-dimensional digital sand table standard module, proposes and devises the embedded control panel that a set of use MCS-51 single-chip microcomputer is CPU, realizing the driving for stepper motor, complete the control to digital sand table standard module.
The digital sand table module array be made up of 3-dimensional digital sand table standard module, according to three dimensional space coordinate information, can present the 3D complexion of landform or image, realizes three-dimensional display; And can according to three-dimensional coordinate, by embedded control panel drive mechanism, dynamic conditioning digital sand table array is to the display of three-dimensional picture.
For above-mentioned purpose, the present invention mainly comprises three aspects: the mechanical hook-up design of 3-dimensional digital sand table standard module; The embedded control system hardware design of standard module; And order about the drivers design of mechanical hook-up movement.
Driving design link comprise again following some: (1) move mode formulate; (2) stroke Preservation tactics; (3) stroke is made mistakes and is revised and recovery policy; (4) Strategy of Data Maintenance of pre-anti-power failure.
One, the mechanical hook-up design of standard module:
Digital sand table device one-piece construction: digital sand table mechanical hook-up is a kind of expansion of information display, and it mainly shows terrain information according to a certain percentage.Experimental sample digital sand table module by 4*4 totally 16 rectangular columns form, each rectangular column can rise or decline certain height as requested, the digital sand table module of risen to certain altitude just can be spliced into the landform complexion of certain area so as requested, reaches the effect of display.
The embodiment of the present invention once completes lifting and drop-down action each rectangular column with a rectangular column (i.e. master control column).Master control column will complete lifts action to each rectangular column, just needs three directions of horizontal both direction (i.e. X-direction and Y-direction) and vertical direction (i.e. Z-direction) operate.So what select in the middle of the design of mechanical hook-up is complete the control on master control column three directions with three stepper motors.And the design related in the design three stepper motors and position arrangement.
As shown in Figure 2, number in the figure a, b, c are the stepper motors of Y, X, Z-direction to the vertical view of the design drawing of this mechanical hook-up respectively, and label d part is middle 4*4 matrix-block, namely 16 rectangular columns.The design of three stepper motors can be recognized by accompanying drawing 2, X-direction stepper motor is at bottom one deck, its operation also can drive YZ direction to move, and Y-direction stepper motor is at middle one deck, its operation can drive Z-direction to move, and last Z-direction stepper motor directly can control master control column and hold up one of them rectangular column.
Master control column and rectangular pillar construction design: master control column will complete the mechanical action to rectangular column, mainly lift and drop-down action, just must have corresponding structure.That is completing that master control column and rectangular column can be worked in coordination is lifted and drop-down action.Inwardly, above master control column, have the design of individual hook, be complete with the respective outer side edges of rectangular column to design master control column in the middle of this structural design, not only can complete the action of lifting and also can complete drop-down action under this coordinates.So, the displaying that not only can complete terrain information also can recover a terrain information.Accompanying drawing 3 is structural design drawings of rectangular column, number in the figure
for the front view of single rectangular column, the hook-shape structure design of column bottom can be seen; Label
for the left view of rectangular column; Label
for the vertical view of rectangular column.Accompanying drawing 4 is the mechanism design figure of master control column, can see the concrete hook-shape structure design in master control column top, can coordinate, complete drop-down action, number in the figure with the hook-shape structure of each rectangular column low side
for the front view of master control column, label
for its side view.
Rectangle square formation 4*4 matrix-block pedestal designs: the thought of display landform is exactly can control 16 rectangular columns freely to rise to different height, therefore design rectangular devices is just needed to be loaded by these 16 rectangular columns, just as each rectangular column design draw-in groove.The thought of design is provided with magnet inside the draw-in groove of each rectangular column, because the superficial layer material of matrix-block pedestal is made up of iron, therefore can by magnet adsorption on risen position after each rectangular column rises to certain altitude, need to pull down by under master control column again when declining, reach the effect be freely elevated.Accompanying drawing 5 is the apparatus design figure depositing rectangular column, number in the figure
with
the front view of rectangle square formation 4*4 module pedestal, left view and vertical view respectively.
Two, the embedded controller hardware design of standard module:
3-dimensional digital sand table module is the control panel of SCM Based stepper motor.Governor circuit as shown in Figure 6, hardware circuit control chip selects 51 relatively inexpensive series monolithic STC90C58RD+, operating voltage: 5.5V ~ 3.3V (5V single-chip microcomputer), the pull-up resistor of the external 10K of P0 mouth, and be connected with PSX, PSY, PSZ tri-travel switch interfaces.In the safeguard measure of digital sand table device, all devise the contact of a travel switch at the two ends in three directions, so need external three travel switch interfaces.That stroke protection module adopts is SN74HC21D type logical AND gate U3A, as long as one end travel switch closing of contact, then logical AND gate output low level, thus the outside 0 of triggering single-chip microcomputer is interrupted.U3B is SN74HC21D type logical AND gate, and input pin connects the ALERT pin of three pieces of stepper motor driver chip respectively, and output pin is connected with single-chip microcomputer INT1 port, and the arbitrary input pin of U3B is that 0 outside 1 can triggering single-chip microcomputer is interrupted.As shown in Figure 7, RS485 interface adopts the Max3085 of enhancement mode to 485 communication interface circuits, and what signal transmission isolation was selected is 6N137 type high speed photo coupling.Stepper motor driving circuit in X-direction as shown in Figure 8; Y, Z-direction are consistent with it; what three road stepper motor driver chip adopted is the TB6600_HG model that Toshiba produces; this model is high-power, high segmentation; two-phase hybrid stepping motor driving chip; multiple segmentation optional (1,1/2,1/4,1/8,1/16), and built-in temperature protection.Driving chip input power is 24V, and a resettable fuse of connecting between power supply with driving chip, prevents electric current excessive and burn out chip.In order to reduce the impact of high-power circuit on control circuit, based on the ground wire PGND of the high-power part of three road stepper motor driver chip, to separate with the ground wire SGND of control section and to design, linking together finally by 0 Europe resistance.The basic circuit of driving chip is with reference to the databook of this chip, and M1, M2, M3 are that excitation mode input pin is connected with single-chip microcomputer, and ENABLE is for enabling signal input pin, and RESET is reset signal input pin, and CW is that forwards/reverse controls pin.The embodiment of the present invention separately adopts 28 direct insertion toggle switchs to mark the machine address of standard module, address realm 1 ~ 65535.
Three, the embedded controller drivers design of standard module:
First, rational mobile alignment is built; Secondly, in stepper motor moving process, the interruption produced owing to makeing mistakes is carried out judging and marking; Again, according to label information of makeing mistakes, recovery policy reasonable in design, revises the part of makeing mistakes or reloads operation; Finally, for sudden powering-off state, design a set of Strategy of Data Maintenance, strengthen robustness and the stability of standard module.The functional diagram of drive software as shown in Figure 9, mainly comprises: move mode, stroke protection, make mistakes revise and recover and anti-power failure data protection function.Particular content is as follows:
1, move mode is formulated: on the one hand, and standard module controls 16 rectangular columns of 4*4 in mechanical hook-up, moves in serpentine, and being designed with of serpentine is beneficial to the displacement of shortening device in X, Y plane.On the other hand, for the movement of rectangular column on Z axis, the embodiment of the present invention devises two cover mobile mechanisms:
The known needs object height of movement and the present level of rectangular column, then adopt the move mode that based target height compares with present level.If object height (m) is higher than current rectangular stem height (n), then only need move up this rectangular column relative height (m-n); Otherwise, then need drop-down for this rectangular column (n-m).
Known rectangular column needs the object height of movement, and does not know present level, then adopt top set pull-down pattern to move: first by supreme summit, rectangular column top, then drop-down relative height difference.
2, stroke Preservation tactics: for improving the stability of stroke and the robustness of standard module, the embodiment of the present invention overflows situation for the stroke of different directions, and devise a set of corresponding determination strategy, strategic process figure, as accompanying drawing 10, specifically describes as follows:
When detecting that the travel switch contact that mechanical model is positioned at X-axis two ends is triggered, and cause single-chip microcomputer outside 0 and interrupt, show that the movement in this direction has arrived the end points of stroke.First, read the signal being connected to three wires of three directional run switches respectively, low level then represents that this direction stroke occurs and overflows; Then, according to moving direction marker bit d, (d>0 represents advance, and advance can only be interrupted at trigger endpoint place; Otherwise, be starting point place interrupt) judge that this position is starting point or terminal: (1) if starting point, then carries out rationality judgement, target location be 0 and initialization operation be considered as rationally, rationally then marker bit rework being set to 0, otherwise putting 1; (2) if terminal, directly marker bit rework is set to 0.
Y-axis deterministic process is consistent with above-mentioned X-axis, and the embodiment of the present invention does not repeat this.
When module detects that the travel switch contact that mechanical model is positioned at Z axis two ends is triggered, show that the movement in this direction has arrived the end points of stroke.Then, its position is judged: (1) if be positioned at starting point, then carries out rationality judgement (initialization operation and object height are 0 be rationally) to the movement of back.If rationally, then marker bit redo is set to 0, and jumps out interrupt routine; Otherwise, then marker bit redo is put 1, and jumps out.(2) if be positioned at terminal, then rationality judgement (initialization operation and object height are 255 be rationally) is carried out.If rationally, then marker bit redo is set to 0, and jumps out interrupt routine; Otherwise, then marker bit redo is put 1, and jumps out.
Above deterministic process all performs in outside interrupt routine.Because mechanical hook-up triggers the rejuvenation after endpoint interrupt, still have the possibility triggering secondary and interrupt, so interrupt routine only carries out the operation of read-write marker bit, and all mobile operations are all arranged in single-chip microcomputer principal function.
3, stroke is made mistakes and is revised and recovery policy: this process is arranged in single-chip microcomputer principal function, and mechanical hook-up often once moves, and all needs the corresponding marker bit of poll after mobile.Particular content is as follows:
After X-direction once moves, check marker bit rework, if 0, then showing to move does not have mistake, continues to move next time; If 1, then show mobile makeing mistakes, mechanical model is reduced to init state, and re-executes whole moving process.
Y direction is consistent with X-axis, and the embodiment of the present invention does not repeat this.
The rectangular column of Z-direction, after once moving, checks marker bit redo, if 0, then showing to move does not have mistake, continues to move next time; If 1, then show that this rectangular column moves and make mistakes, module is only carried out local amendment to current rectangular column or is recovered.
4, the Strategy of Data Maintenance of pre-anti-power failure: in order to tackle the sudden powering-off state in actual environment; the embodiment of the present invention devises the Strategy of Data Maintenance of complete set, and the data object of main protection is the status indication that 16 object height information and each elevation information are corresponding.In EEPROM, the target data storage format of 0x8000 sector as shown in Figure 11, and Z [1] to Z [16] is respectively 16 object heights, and state [1] is respectively the validity of respective heights data to [16], and 255 is invalid, and 1 is effective.In EEPROM, the data mode form of 0x8800 sector as shown in Figure 12, EEPROM_state is the state of data in EEPROM, 255 represent countless certificate in 0x8000 sector, and 1 represents that in 0x8000 sector, data are imperfect, and 0 represents that in 0x8000 sector, data are complete.Realization flow as shown in Figure 13, specifically describes as follows.
Write EEPROM process: first, when standard module receives the target position information that upper strata repeater sends, at once these data are saved in the EEPROM of single-chip microcomputer; Secondly, it is 1 by EEPROM_state mark position that major cycle starts front, has often successfully moved a rectangular column, the state of correspondence position in EEPROM is set to 1 in major cycle; Finally, 16 rectangular columns all successfully move complete, are 2 states by EEPROM_state mark position.
Read EEPROM process: when 3-dimensional digital sand table standard module electrifying startup, first the EEPROM_state read in EEPROM marks and analyzes:
If EEPROM_state is 255, show in hardware circuit single-chip microcomputer first time use or singlechip chip there occurs replacing, countless certificate in 0x8000 sector in EEPROM.Program then enters major cycle and waits for that new data arrives.
If EEPROM_state is 1, mobile operation was just there is before showing this electrifying startup of standard module, and do not complete whole movement just unexpected power-off, therefore according to the target position information preserved in 0x8000 sector in EEPROM and state, whole device need be recovered again.
If EEPROM_state is 2, the complete execution of mobile operation before showing this electrifying startup, therefore the data of preserving in 0x8000 sector are the positional information of 16 current rectangular columns.
Several standard modules scrabble up digital sand table module array by vertically and horizontally arranged, form complete huge entity digital sand table.The demand that the scale of module array can be shown according to reality freely reduces or expands, and scale is larger, and the quantity of required standard module is more; Otherwise demand is fewer.Show large-area geography information if need in actual environment, then increase square formation scale, the quantity of standard module can increase to tens thousand of pieces.
3-dimensional digital sand table standard module is the elementary cell forming entity digital sand table.The hardware and software of each standard module is identical, has consistance and reproducibility, for actual medium quantity batch processing provides great convenience.The hardware address of standard module then by hardware toggle switch manual control, in order to the differentiation between module.
3-dimensional digital sand table standard module, as elementary cell, has the independence of height.The behavior of each standard module is only controlled by the embedded system of itself.Directly do not contact between module and module and affect.In reality, if exception error appears in some standard modules, other standard module does not affect by it.
Preferred forms
When making circuit board terminal, the circuit provided in the recommendation embodiment of the present invention, the 0 Europe resistance suggestion be connected between the Power Groud of driving circuit and the signal ground of control circuit connects, to reduce both mutual interference;
Outside 0 interrupts being the interruption triggered after closing as travel switch, only carries out the operation of read-write marker bit, should not carry out stepper motor and move generic operation, otherwise can block secondary interruption in suggestion external interrupt program.Any stepper motor moves generic operation and is all placed in major cycle and carries out;
When preserving target data in EEPROM, EEPROM_state marks to divide from target data and is opened in different fan pages.Because time in EEPROM to data modification, must first wipe whole fan page, then just can carry out write operation; Therefore in order to not affect target data when writing EEPROM_state, both must separately deposit.Be STC90C58RD+ class single-chip microcomputer for model, recommend EEPROM_state label information to leave the fan page that first address is 0x8800 in, target data leaves the fan page that first address is 0x8000 in.
