Description
Technical field
The invention belongs to single-chip microcomputer design field, particularly relate to a kind of Infrared remote controller recognition by pressing keys system and using method thereof of single-chip computer control system.
Background technology
When using single-chip microcomputer deisgn product, designer is often required that product must have function of infrared remote control, and they will select a kind of remote controller from the market, some buttons are fallen with mask sheet, according to conceptual design, in position the upper button retaining sufficient amount, then specifies the function of each button.As a part for product software, Infrared remote controller key code recognizer must be worked out, so that the function program forwarding each button defined to goes to realize corresponding function.
Present situation is: on market, the Infrared remote controller of various model is multifarious, and their coded format is also different, and designer is often stuck in here, can not work out key code recognizer, cannot carry out next step design.
The SCM Based infrared remote control code identification method delivered at present has:
1, the model (such as uPD6121) of known remote control coding chip, and from data, find its coded format: 32 codings, a lead code (9MS high level, 4.5MS low level), logical zero is 0.56MS high level 0.56MS low level, and logical one is 1.68MS high level 0.56MS low level, 8 user codes, 8 user's radix-minus-one complements, 8 bit data codes, 8 bit data radix-minus-one complements.More than after 108MS being running fire code (9MS high level 2.5MS low level).According to so detailed encoding format information, by time delay wait method or add outer interrupt method with timer and identified, find 32 binary codes of each button, then they are compiled in product program respectively, to forward the program segment that same keypress function is corresponding to, complete corresponding function.
The shortcoming of this method is:
Before establishment product program, first must determine the model of coding chip in remote controller, search data, determine coded format, this code of remote control recognizer could be worked out.But often cannot determine chip model, or can not find related data, use Design of Infrared Remote Device Utilizing product person to first, oneself compiles recognition by pressing keys program is a difficult problem.
Physical location and its function of button are fixed by program, want to change its function, must rewrite program.
If initial selected remote controller stops production, can't buy, or had more cheap, more good-looking, want to change remote controller, then must rewrite program, equal to redesign software.
2, recent, occur being called as " coding/decoding method of intelligent infrared ray remote control system " (Weifang College's journal the 10th volume the 6th phase), this method does not consider infrared coding form, the time that direct calculating same logic continues, and judge two kinds of different logics according to the ratio of duration, represent with " 0 " or " 1 ", the launching code of each button in Infrared remote controller is obtained after decoding, and these launching codes are stored, when needing, then by encode accordingly through modulation after launch.
In this article, remote controllers all in family combines by (object of the method is), namely realizes a remote controller or all electric equipments that can receive infrared remote control of machine control.For this reason, author, while making infrared receiver/decoder module, has has also designed and produced infrared transmission module.
Obviously, such method just copies the coded excitation function of other remote controller, can not provide recognition by pressing keys for single-chip microcomputer designer.Can not for designing the product of various controlling functions.
And can not shelter be had between infrared transmitter and receiver, and should mutually aim at.Electrical equipment in family is that dispersion is placed, if this device can not be hand-held, how to use? the function i ntegration of various remote controller on a device, its keypress function is different, and quantity is a lot, how to facilitate certain function of certain remote controller selected quickly directly perceived? these problems there all are not solution.
3, " design of universal infrared remote-control decoder " delivered on " modern electronic technology " magazine on August 15th, 2011 (Dong Feng more than 63999 armies, National University of Defense technology Liu Qiang), mathematical measure used, by vector quantization and clustering procedure, the problem that the pulse duration solving identity logic level has some to disperse, solves by iterative method the problem that code repeats transmission.
The shortcoming of the method is:
Its function, with method 2, for designing the product of various controlling functions, can not just copy the function of certain remote controller.
In fact, as long as select the suitable numeration pulse period to measure the pulse duration of logic level, its decentralization is limited (comparing with pulse duration), just can deal with problems with simple Logic judgment (several instructions); Generally, after an information is sent, there is the code that terminates, its pulse duration is much larger than the width of other pulse, just can the end position of simple determination information by Logic judgment, there is not duplicate message and take storage resources problem, so much mathematical measure need not be used.
4, on " microcomputer and application " magazine the 30th volume the 21st phase, within 2011, delivered the paper " Infrared remote controller decoding software design and application " of University Of Science and Technology Of Shandong's Liu Wanbin.
Its function is: the infrared coding decoding each key when not grasping the coded format of remote controller.
Its method is: the width adding each pulse of method record of timer counter with outer interruption, judges cognizance code.Then the same code compiled in a program compares, and time identical, namely turns to corresponding program section, performs corresponding function.
The shortcoming of the method is:
Require that designer first determines remote controller, write its code recognizer, determine the code of each button, the program of being enrolled compares in statement and (does not store the code of all buttons).When having button to press, its code is compared with the code enrolled in program statement, then forwards each program segment to.
The shortcoming of the method is:
Just code identification, be not the identification of button sequence number, the function of each button is just fixed in the dust by program, want to change the physical location of button, want to change remote controller, just must coding again, having certain difficulty, is not that everybody can easily complete. not only time-consuming but also require great effort.
In sum, any method up to the present all must write code of remote control recognizer by designer voluntarily, and after program compiles and edits, just with remote controller and on button be fixed together, change remote controller, or change the position of keypress function on it, all must rewriting program.

Fig. 2 is the using method flow chart of the Infrared remote controller recognition by pressing keys system of single-chip computer control system.First the Infrared remote controller recognition by pressing keys system of single-chip computer control system provided by the invention will carry out button learning process.Because PIC single chip microcomputer system designer is all familiar with the usage of MPLAB-ICD2, therefore, the general operation of the present invention to MPLAB-ICD2 does not repeat.Button learning process can be carried out in both modes:
Pattern 1, on-line operation pattern
Step 1: carefully connect the wire by shown in Fig. 1 (first not adding 220 volts of power supplys).In figure: " recognition by pressing keys developers DMSB.DDB " in dotted line frame is hardware provided by the invention (base of PIC16F876A is the movable base of band clamping); PC is personal computer; ICD2 is PIC single chip microcomputer in-circuit debugger (on sale on market, to comprise 9 volts of power supply adaptors); On sale on 5 volts of D.C. regulated power supply markets.
Be that the blank chip of PIC16F876A clips on the movable base of DMSB.DDB by model; Connect 220 volts of power supplys, to system power-up.Setting Infrared remote controller needs the key number N used.
Step 2: be the key assignments sequence number in Infrared remote controller, sequence number is from 1 to N, and each button can only distribute 1 sequence number, the physical location of button in Infrared remote controller can be fixed arbitrarily by designer.
Step 3: mode selector switch circuit is switched to button mode of learning, switches to on-line operation pattern by operation switching switch circuit.
Step 4: with ICD2 single-chip microcomputer in-circuit debugger, under Debugger pattern, key code identification source program DMSB1.ASM provided by the invention is compiled into machine code program DMSB1.HEX, and writes PIC16F876A.
Step 5: run DMSB1.HEX program with ICD2 on hardware DMSB.DDB again.
Step 6: then Infrared remote controller is aimed at the light-receiving head TL538 on DMSB.DDB, at least every 2 seconds, presses the button remote controller successively from 1 to N; Often by a button, the LED (L5, L4, L3, L2, L1, L0) on DMSB.DDB can with binary number (L5 is highest order, and L0 is lowest order) show this by the sequence number of button.Please note and observe the sequence number of institute by button whether with showing; Must depresses button successively in order, otherwise just misplaced.6 LED that the present embodiment provides can show 63 keys altogether, substantially enough, more than 63 time only a high position do not show, button learning process still can normally be carried out.
More than after operation, learning process terminates.
Pattern 2, offline operation pattern
Step 1: carefully connect the wire by shown in Fig. 1 (first not adding 220 volts of power supplys).Be that the blank chip of PIC16F876A clips on the movable base of DMSB.DDB by model; Connect 220 volts of power supplys, to system power-up.Setting Infrared remote controller needs the key number N used.
Step 2: be the key assignments sequence number in Infrared remote controller, sequence number is from 1 to N, and each button can only distribute 1 sequence number, the physical location of button in Infrared remote controller can be fixed arbitrarily by designer.
Step 3: mode selector switch circuit is switched to button mode of learning, switches to on-line operation pattern by operation switching switch circuit.(switch S namely in Fig. 1 on DMSB.DDB and S1 open).
Step 4: with ICD2 single-chip microcomputer in-circuit debugger, under Programmer pattern, key code identification source program DMSB1.ASM provided by the invention is compiled into DMSB1.HEX program, and writes PIC16F876A.
Step 5: disconnect 220 volts of power supplys, crystal head is taken off from DMSB.DDB; Operation switching switch circuit is switched to offline operation pattern (closing by the S1 on DMSB.DDB in Fig. 1), mode selector switch circuit is still in button mode of learning.5 volts of D.C. regulated power supplies are received on 220 volts of power supplys, powers up to DMSB.DDB.Now just start to run DMSB1.HEX program on hardware DMSB.DDB.
Step 6: Infrared remote controller is aimed at the light-receiving head TL538 on DMSB.DDB, at least every 2 seconds, presses the button remote controller successively from 1 to N; Often by a button, the LED (L5, L4, L3, L2, L1, L0) on DMSB.DDB can with binary number (L5 is highest order, and L0 is lowest order) show this by the sequence number of button.Please note and observe the sequence number of institute by button whether with showing; Must depresses button successively in order, otherwise just misplaced.
More than after operation, learning process terminates.
After above-mentioned button learning process terminates, in order to reaffirm whether the sequence number of button correctly stores, and can perform one-touch identifying, namely
Step 7: mode selector switch circuit is switched to recognition by pressing keys pattern (closing by the S key in Fig. 1), make system be in " recognition by pressing keys " pattern, arbitrarily press any key, checks that whether LED show value is identical with institute's button sequence number.
Cause this, button learning process completes, and the code identification of button also completes automatically, and has suffered stored in the EEPROM of PIC16F876A sequentially.
Next, be button sequence number recognizer (DMSB2.ASM) provided by the invention is linked up with user program form end user program DMSB.ASM, compiled and write chip.
Step 8: operation switching switch circuit is switched to on-line operation pattern (opening by the S1 on the DMSB.DDB in Fig. 1).
Designer is by the design of oneself, and the following Infrared remote controller used of regulation always has how many buttons (assuming that being N number of), and specifies that their sequence number is successively: 1,2 ..., N.Specify the function that this N number of button will complete separately, and write the application program (DMSB3.ASM) of oneself according to the function that will complete.
Button sequence number recognizer (DMSB2.HEX) is when no button, be in wait state, ceaselessly inquire about on remote controller and whether have key presses, once have, just identify pressed key code, then the code that this code stores with EEPROM in PIC16F876A is compared, time identical, just find out the position of this code in EEPROM, because code stores in order, program also just calculates the sequence number of this button, and sequence number is determined in " button study " stage with the corresponding relation of button; Button sequence number recognizer is in a ram cell of this sequence number write singlechip chip PIC16F876A, and this element is exactly the register K used in program DMSB2.ASM.
At DMSB2.ASM procedure epilogue of the present invention, designer should dose query statement, and numerical value in inquiry K, according to Query Result, is automatically brought to corresponding program section, completes corresponding controlling functions.So just complete (the program DMSB3.ASM of DMSB2.ASM with user oneself) software linker.Program after link is end user's program (DMSB.ASM).
With ICD2 under Programmer pattern, program DMSB.ASM is compiled into DMSB.HEX, then it is write the program storage (note: only program writing, destroy the data in EEPROM) of PIC16F876A.(in " button study " stage) is by the EEPROM of the code of N number of button write PIC16F876A before this.
Step 9: last, takes off PIC16F876A chip from DMSB.DDB, inserts on the single-chip computer control system of designer oneself, can run the product of its design.
To programming chip in batch, then can using the PIC16F876A chip (as master slice) finished writing in upper step, be clipped on the active socket of recognition by pressing keys developers DMSB.DDB, click Readtargetdevice and ReadsdeviceEEPROM on PIC single chip microcomputer in-circuit debugger MPLABICD2 respectively, key code in DMSB.HEX and EEPROM on master slice is read, take off master slice afterwards, blank PIC16F876A chip on folder.Under Programmer pattern, the data write blank chip in DMSB.HEX and EEPROM, just complete programming process.So return multiple operation, multiple chip can be write.
For a long time, engineers and technicians design use the single-chip computer control system of Infrared remote controller time, suffer from and do not know how in the design of Infrared remote controller for oneself, and the existing method delivered, there is many shortcomings, not easily use, not easily grasp, nimble not.
Use system and method provided by the invention, designer can arrive market and buy the Infrared remote controller oneself liked, and arrange and press bond number N, leave N number of button in place, button facial mask unnecessary on remote controller covers.This N number of button is paid in sequence number 1,2 respectively ... N.Controlling functions in the sequence number of button and application program must one_to_one corresponding, but the physical location of button oneself is selected.The button of different sequence number completes different controlling functions.Certain sequence number can distribute to any button physically on remote controller, only it is to be noted that difference button physically can not distribute identical sequence number. and a button can only have a sequence number.Afterwards, first will complete above-mentioned button learning process, after learning process completes, program has all suffered the code of N number of button stored in the EEPROM of PIC16F876A.Finally, button sequence number recognizer be connected with user program and write chip, not knowing of running into when designer designs Single Chip Microcomputer (SCM) system can be solved and how carry out by Infrared remote controller the difficult problem that designs.
The present invention gives technical staff's powerful in this field vast: the puzzlement having broken away from the identification of Infrared remote controller key code, need not oneself design with the relevant program of Infrared remote controller, only need use hardware and software provided by the invention, just can be simple and direct and design single-chip microcomputer infrared remote control system flexibly.Decrease design difficulty and workload, shorten the design cycle, improve efficiency.Utilize native system, can also programming chip in batch, eliminate fever writes, reduce cost.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
