Be described further below in conjunction with embodiment:
Fig. 1 is a kind of theory diagram of apparatus of the present invention.MCU is the Single-chip Controlling unit center among the figure, formed by single-chip microcomputer and peripheral supporting component thereof, EPR is the electrically-erasable memory EEPROM supporting with MCU, be used for the timetable of program storage time and the music inventory of each " music group ", if single-chip microcomputer self is with inner current failure memory memory, STC89C54 as embodiment uses then can save independently EEPROM.SD is music storage, be used for storing music, select moveable magnetic disc (SD card or USB flash disk) as music storage among the present invention, so that the user pulls out them to be inserted in the computer easily and edits: MP is the online music processing enter of music unit, it comprises computer network music decoding chip and solution digital signal is out converted to the digital to analog converter of simulating signal, and some necessary peripheral supporting components, being responsible for will be by the numerical information (MP3 of the appointment music after the certain format compression, MP4 etc.) from music storage, access, carry out decompress(ion) and contract and be reduced into simulating signal.MP and SD form the music unit that is subjected to MCU control, it is carried out the instruction of MCU and in time the appointment music in the music storage is decoded and format conversion, then the music simulating signal after will changing is delivered to audio signal processor MUP and is carried out further audio frequency processing and prime amplification, be transported to again power amplifier (power amplifier) PE and amplify, then be dispensed into the loudspeakers such as sound column, audio amplifier and play.Power amplifier PE is placed in the system of the present invention, is only suitable for the situation in small-sized use occasion, for general dance hall and large-scale dance hall, required musical power is quite large, and power amplifier should be support equipment independently.The power supply of PE is subjected to the control of MCU, and when not having music playing for a long time, MCU can cut off the power supply of automatic PE.
The button signal input block that INP representative input command information is used among Fig. 1; DIR is display unit, contains charactron or liquid crystal display and driving circuit thereof.
Consider that the practical application scene may need to change the broadcasting situation temporarily, added wireless remote controlled receiver WLR among the present invention in the host computer system, the telepilot WLS that it is supporting, the host do a little interim changes to automatic playing program in the case of necessary just can optional position at the scene like this, as certain dance music of replaying, time-out, increasing reduce volume etc.Wireless remote controlled receiver WLR can buy finished product on the market, as long as arrange several input terminals to link to each other with the receiver of remote-control sytem lead-out terminal in host computer system, then gets final product with inquiring about or carrying out information processing with the mode of interrupting as processing conventional push button.
The key of successful Application of the present invention is writing of software.Actual software comprises that software for display (showing week, time, group number, sequence number and sound cornopean), timed sequence software, user select music from music storage and deposit the program of " music group ", from the RAM of chip information write program the EEPROM, from EEPROM fetch program and the some software such as broadcast, mostly these softwares are known software, here it will not go into details, just the present invention innovated part and set forth.
At first to determine the size and number of " music group " memory block, consider: music group should divide according to different use occasions, different crowd needs or different application purpose, as the front music of going to work, work-break exercises music, playground music, lounge music, square dance music, social dancing music etc., for the dance hall, the social dancing music can be finished again several covers and play in turn, to improve feeling of freshness; Dance music in square also should be divided into groups according to different time or according to the needs of teaching, uses possibly many groups of music on the same day, so the quantity of music group wants enough, selects 50 among the embodiment.The size of music group will be considered the continuously time of broadcast, and the square of for example putting an afternoon is waved music, put the social dancing music of a whole night, selects 99, two figure places to show among the embodiment
Device can show, and is generally also enough.According to quantity and the size of music group, select suitable EEPROM.
General regularly broadcasting procedure has two parameters: the timed task in master variable time and the corresponding moment---intend the sound cornopean of music playing, the code of sound cornopean is generally the set of number of two byte representations, if its conventional letter is yyH (upper byte) and yyL (low byte), such as the yyH=03H of No. 356 music, yyL=56H.Apparatus of the present invention are selected certain number outside the sound cornopean upper byte digital scope, and (the quantity design of storage music is no more than 0999 head among the embodiment, the yyH numeral is between 0-09, so can select OAH) representative " broadcast group music ", thereafter yyL represents the group number of music group, for example OA08 just represents and plays group's music of the 8th group, so just the instruction of " play group music " is become set of number certain song of picture broadcast, can be easily to its carry out timed sequence programming with command operating.
Automatically playing group's music, generally is that order one song that requirement connects in the music group connects bent (chain broadcast) of playing continuously, and the chain broadcast program can be write by the method shown in Fig. 2 block scheme.LbQ enters chain broadcast group musical logo among the figure; ZH is music group group number, and XH is the sequence number (broadcast sequence number) of certain music in the music group list; EPRi is the information in certain music group memory block in EEPROM, RAM is the RAM memory block in the single-chip microcomputer, this is the public convenient memory blocks of reading and writing of a plurality of music groups, and EPRi → RAM meaning is that the music inventory that will have certain number music group on the EEPROM copies to single-chip microcomputer internal SRAM storer; XHmax is the maximal value of sequence number, and XH 〉=XHmax means that the space of this music inventory all looked into, and can not find the song that will play again.
For the noise that reduces the consumable accessory volume potentiometer disturbs, simplify circuit, simultaneously also for the needs of remote control adjustment volume, in apparatus of the present invention without volume potentiometer, and adopt action button to regulate volume, its Principle Method is: adopt the volume value at music playing just can read of selling on the market now, regulate the MP3 module (containing the circuit that has the executive software instruction to change volume) of volume with useful instruction, read its volume change scope, and convert thereof into and be easy to the digital V that shows and use, among the embodiment with its conversion, be shown as 0 to 90 grade, then itself and volume prevalue V0 are compared, bigger than normal, just the MP3 module is sent the instruction that once reduces volume, vice versa, so repeat, until the volume value of reading equals prevalue, this has just realized that actual broadcast volume is from motion tracking volume prevalue, and the volume prevalue increases or reduces by action button under tuning amount state, and namely this device has realized adjusting with action button the function of volume.Fig. 3 is button tuning amount theory diagram.
The dancing party music has individual characteristics to require exactly per song not too long, oversize, and the dance hall customer can feel exhausted and be weary of, it is generally acknowledged be controlled at about 4 minutes proper.But, many music of downloading from the Internet, its reproduction time all exceeds above-mentioned boundary, the inconvenience that brings for solving overlength, this device utilizes above-mentioned volume control principle, developed the fixed length diminuendo closing function that the method that automatically weakens with volume realizes the overlength music, to satisfy the special requirement of dancing party, its principle as shown in Figure 4.The not all model all situations of this function all will be used, so should have individual switch and so on device or a kind of special push-botton operation to allow the user select as one sees fit, the xcQ=1 representative has the sign that needs the music limit for length among the figure, " time-delay " is to select according to the speed that volume reduces among the figure, general desirable about 1～2 second.
Same according to top principle, this device has also designed " hypnosis music " function: we will be suitable for the music (be conducive to the light music of hypnosis and with magnetic special recording) of hypnosis and compile advance specifying special-purpose music group (for example the 50th group) inner, in the time will playing the 50th cohort group music, just automatically start the slow diminuendo function of volume: volume weakens gradually with speed very slowly, until a very long time (for example half an hour or one hour) just drops to volume zero, when volume reduces to 0, turn off this group music.
Apparatus of the present invention have many cover timed sequences, add the grouping playing function, bring many convenience to the user, have also become greatly but overlap, how organized later programing work amount.Our research is found to remain with many identical key elements between different covers, the group, for example the program of school's weekend (Friday) usefulness with use Thursday almost completely the same, Friday just in advance any classes are over; When dance music was changed in dancing party, it was constant to keep most of dance music, the responsive dance music of the amount of tailing off more only, and opening remarks are the same with the dancing party conclusion at least, the Changing Pattern of dancing classification is (such as rumba → fast three → Jitterbug ...) also can remain unchanged; In order to alleviate user's programing work amount, write into the software that copies a whole set of timed sequence and whole music group music inventory in apparatus of the present invention, realize whole group, the copying of a whole set of program, namely realized respectively overlapping mutually copying between the timed sequence and between the music group.In fact, Here it is with the information reproduction of certain memory block on the EEPROM to another memory block, its functional-block diagram is seen Fig. 5, " EPRy → RAM " will provide the Information Read-Out of the source music group (or source timed sequence) of message sample from EEPROM among the figure, again it is write in the single-chip microcomputer RAM storer, " RAM → EPRm " is from the Information Read-Out of single-chip microcomputer RAM storer is write target music group (or target timing program) the EEPROM, complete copy command is generally inputted by certain operating key in groups, bump button and cause totally losing of target music group data in order to prevent mistake, in software, introduce time-delay and twice inquiry " in groups complete copy command is arranged? ", make troubles to avoid maloperation.
Often to use " the interim appointment replaced " (temporary changes of timed sequence or music group) of music group or timed sequence in the practical application, for example, the setting-up exercises during the break time science is proofreaied and correct the normal relevant music of one group of outdoor sport of playing, When the Rain Comes but run into, just should not play the relevant music of outdoor sport, and should play one group of indoor music (the setting-up exercises to music time uses " eye exercises music group " to substitute " square setting-up exercises during the break music group " temporarily) of health protection behaviour of doing; And for example, automatic outdoor dance hall is one group of dance music of fixed time airplay every night, rains or there is special applications etc. on the square but run into, and just should break dance music, and change into fixed time airplay " dancing party tonight suspends for some reason ... "We just add " the interim appointment replaced " function in program in embodiment 2, Fig. 6 is the embodiment of a kind of " will substitute in the certain hour ", " specify replacement instruction " among the embodiment temporarily and be certain button of pressing telepilot by managerial personnel to send, TDQ is the sign of " will temporarily substitute (change cover number or group number) " among the figure, finger will put 1 with TDQ behind alternative command, (for example having become a fine day) will send instruction TDQ is resetted (setting to 0) when no longer needing to substitute; Specify beginning (stopping) execution time, refer to beginning (stopping) and carry out the interim time that becomes cover, for example should begin to play under normal circumstances dance music in 19: 30, but do not held dancing party rainy day, should shift to an earlier date and repeatedly notify everybody, for example notified several times since 18 o'clock minutes, " Starting Executing Time " can elect 18: 0 as; T is this device clock time.
The chance of using apparatus of the present invention when individual or small collectives outdoor activity is also a lot, for example class's outdoor activity of kindergarten or school, the square dancing party of holding in the vacant lot, streets and lanes, this dancing party is often small, required musical power is not very big, but mobile large, their needs have been considered among the present invention, the model of a kind of pocket of specialized designs, adopt small-sized for this reason, portable cabinet, and consider that use occasion may not have AC power, and be designed to AC/DC for this type, namely also can be with the battery use of directly powering, also can consider loudspeaker and necessary power driving circuit and apparatus of the present invention thereof are assembled in the casing, like this, a portable instrument is just passable, very easy when going out.In order to prolong the serviceable life of battery, this device has an AC power testing circuit, when the display screen that detects is not having in the AC power situation, generally do not show (dark screen), only the following period of time after having the people to press action button shows a little while, its software engineering can be achieved like this: when push-botton operation is arranged, set up a button sign, after time-delay in several seconds (delaying time or the software delay of generally delaying time in the program when clock is walked), the reset button sign is inquired about in software for display again, when finding AC power without electricity (will have power supply to detect the loop in the circuit design), when not having push-botton operation, just do not show yet.Certainly, adopt LCDs, also can reach the purpose of economize on electricity, just its brightness is generally not as luminotron (LED) digitron display screen.
Apparatus of the present invention also are applicable to personal office and family very much, for the user provides better service, have designed " Mytip function " for the individual uses in apparatus of the present invention, even this device has the prompt facility of long time period concurrently in this case.We with timed sequence divide growth cycle (take year as cycle period) regularly and short cycle (take day as cycle period) regularly, and manage to allow long period timed sequence and short period timed sequence and deposit dual-purpose.The Principle Method that solves this requirement is such: in the timed sequence of many covers, we determine general procedure all be day circulation (with the time be divided into time parameter, organize music as task take certain head or certain), but a certain cover of rigid appointment (formulating the 9th cover timed sequence among the embodiment) is the long period timed sequence, its time parameter is the moon, day, or music that certain group acquire a special sense first take certain as task (such as the lover's prattle recording of using Valentine's Day, commemoration day birthday is used group's music of congratulating word and " happy birthday to you " song with the birthday), its programmed method short period timed sequence the same (known technology).The execution of long period timed sequence is like this design: the set time of every day (as 8 of every days just, can be more than once), take the moon, day as time parameter, inquire about long period timed sequence (the 9th cover of embodiment), as finding playing task is arranged, namely play.
