Description

Broadcasting device capable of automatically updating music

Technical Field

The invention relates to a voice and music playing device, in particular to various automatic broadcasting devices. The device consists of a microcomputer system (comprising a singlechip, an electrically erasable memory and a time display device), an input device for inputting instruction information and a matched memory card or a U disk (hereinafter collectively referred to as a 'music memory card') such as an SD card which can be scrubbed and re-recorded, wherein the electrically erasable memory is programmed with a timing program, and the matched music memory card is used for storing music.

Background

In kindergartens and schools, instruments for playing music regularly are often used, and even in institutions, communities and parks and even in conditioned families, automatic broadcasting devices are often used for playing background music or for providing music for collective activities of the masses. But the general timing broadcast instrument is not good enough in use effect, mainly the music played every day is the same, the program function is single, the method of programming a set of program every day is used for changing the music playing, and the problem also exists, because each set of timing program can only play a plurality of fixed music, a plurality of sets of programs can only change for several times, the range of variation is very limited, the regular broadcast is repeated after a period, if no manual intervention exists, the regular broadcast plays again every week later; many sets of programs need to be compiled, and the programming workload is much larger.

Disclosure of Invention

The invention aims to provide a music automatic broadcasting device which can automatically update the broadcasting content by a set of timing program, reduce the programming workload and the management work of the automatic broadcasting device, enable listeners to listen to different music every day and avoid the feelings of heavy and boring old and heavy tuning and no taste.

The purpose of the invention is realized as follows:

(1) the music in the music memory card is classified and sorted according to the levels, so that the levels are clear, the categories of the large categories and the small categories are clear, the music sorted according to the principle can be separately distributed in folders with different levels and different categories under the permission of the reading capability of a music playing part, and then all music is uniformly numbered according to the classification order, so that each music number corresponds to one piece of music in the music memory;

(2) dividing an electrically erasable memory in a microcomputer system into several parts, wherein one part is used for editing a timing program, one part is used as a register, one part is used for storing the music of the continuous broadcasting group, a set of software is edited to ensure ① that a user can choose a group of music numbers or instructions in the continuous broadcasting group, ② can play the music in the continuous broadcasting group sequentially or execute the program programmed in the continuous broadcasting group by the user;

(3) in a register or an electrically erasable memory EEPROM of a microcomputer system, a lot of music number variables Δ (a variable for changing the music number of a played music) are stored, and in the played music, a part of music is played with a music number calculated according to the following formula:

YYh＝YYho+Δ

where YYh represents the music number to be played and YYho represents the user-specified start music number; and delta represents a music number variable.

(4) Software is edited to add 1(Δ +1) to the music number variable Δ at appropriate times. This is a commonly known technique, but when editing the software, care should be taken to clear the music number variable when it exceeds a certain limit Δ max, or when it causes the music number calculated by the above formula to exceed the total number of music.

The invention makes the broadcasting instrument have higher intelligence, one set of program replaces tens of past programs, greatly reduces the programming work of users, simplifies the management work of the automatic broadcasting device, can realize the functions of random continuous broadcasting, classified continuous broadcasting and automatic updating of broadcasting contents every day or every week under the condition of little management work or even unattended operation, and can make listeners hear different music every day by using the instrument to broadcast music, thereby avoiding the boring feeling of broadcasting of old tune.

The following is further illustrated with reference to the examples:

⑴ the automatic broadcasting device is controlled by digital instruction control technology, wherein the device for inputting control signal is equipped with a digital keyboard with ten number keys of 0-9, a part of the digital (digital instruction) sent by the digital keyboard is in one-to-one correspondence with the action of the controlled device, the software of the invention ensures that the user can control the controlled intelligent device by directly inputting digital instruction or editing the digital instruction in the timing program;

when the device reads the digital instruction, the microcomputer chip decodes the data of the digital instruction and skips to execute a certain set of action subprogram corresponding to the digital instruction, and drives each part of the device to complete a set of broadcast action corresponding to the digital instruction according to the subprogram requirement.

The following table is a four-digit numerical instruction table (see "numerical instruction control technology") used in this embodiment:

6005 force the power amplifier on;

61xx-65xx entering the daily update broadcast, xx the broadcasters range (space);

68xx, continuously broadcasting the xx group music;

7005 turning off the power amplifier which is turned on by force;

71xx-75xx enters a weekly update broadcast, xx continuous broadcast range;

81xx-85xx classification continuous broadcasting, xx continuous broadcasting range;

89 xx: starting random continuous broadcasting;

xxxx, when Xxxx is less than or equal to the total number of music, playing the Xxxx music.

⑵ classified continuous broadcasting, editing and executing the program of 'adding 1 to the variable of the music number after playing a piece of music each time', namely calling 'adding 1 to the variable of the music number delta f' (delta f represents the variable of the music number for classified continuous broadcasting) after playing a piece of music each time, thus realizing the function of playing the next piece of music after playing the piece of music each time, and because the music numbers are classified, if the initial music is the first music of a certain type of music, the next piece of music is the same type of music, so we call the continuous broadcasting as classified continuous broadcasting.

The sort burst actually takes two consecutive instructions to complete, the first being 81xx-85xx and the second being the designated start music number xxxx. In the command system, xx in 81xx-85xx represents a range of classified continuous broadcasting (the number of music played in a cycle, that is, the number of music of the same category), for example, 68 children english songs are played from 1325 in a music memory card before every day of school, so long as 8168 is programmed in a timing program before the school, and then a 1325 command is programmed, and a programming method of the timing program is known in the art and is not described herein. Here, it is to be noted that:

1. 81xx-85xx represent 5 similar "sort through" commands, which also correspond to 5 music number variables Δ f1- Δ f5(Δ f represents "music number variable for sort through"), these 5 commands being directed to 5 different sort through items, such as "pediatric English song through", "down poetry through", "idiom story through" …. Furthermore, the music number variables Δ f for several classified continuous broadcasts should be stored in a register or an electrically erasable memory EEPROM, respectively, so as to ensure that music that is not played today is played next each time it is played next.

2. Xx of 81xx-85xx represents a range of classified continuous broadcasting, and the continuous broadcasting range is limited by two digits, and only 99 pieces of music can be continuously broadcasted at most. If the number of music of the same category exceeds 100. It is possible to divide them into several sub-100 shares, (volume, division) such as the first and second Tangshi shares, and to play them in batches, or to use six digit instructions if 300 seconds are necessary.

⑶ random continuous broadcasting, editing and executing software for "adding 1 to the music number variable repeatedly and continuously in the main program or the display program", so that the music number variable deltas (the music number variable of the random continuous broadcasting is expressed by deltas) is continuously added with 1 and continuously cleared, the software loop execution result is that the music number variable becomes a randomly changed value, certainly the music number calculated by the software loop execution result is also a randomly changed value, the music played continuously in this way is the random continuous broadcasting music, similar to the classification continuous broadcasting, the random continuous broadcasting is actually completed by continuously executing two instructions, the first is 89xx, the second is the designated start music number, xx in the case 89xx is defined as an invalid number, because the random continuous broadcasting in the embodiment is mainly used for the playing of the leisure music, the setting of such a simplified operation that the range of the random continuous broadcasting is from the designated start music to the last music, and the software processing is that when the music number variable of the music number calculated by the formula exceeds the music number variable of the above formula, the random continuous broadcasting is automatically cleared again because the Δ s is the random continuous broadcasting number, and only the Δ s is needed to be used for a plurality of the random continuous broadcasting.

It is also important to note that: the classified continuous broadcasting and the random continuous broadcasting are continuously circulated, and the broadcasting is not continuous, so that the broadcasting is manually closed after the broadcasting is started, or a timing program which stops the broadcasting is compiled at the scheduled closing time.

⑷ automatically update broadcast every day or week, editing and executing software for "adding 1 to the music number variable at a certain time of day or a certain time of day of week" can make the device of the invention have the function of automatically updating broadcast content every day or week, similar to the classification continuous broadcast.

⑸ group synchronized update broadcasting, the above-mentioned usage is that the user directly inputs the above-mentioned instructions or edits the above-mentioned instructions in a timing program to control the execution of the apparatus, and there is also an important usage that the software allows the user to edit the daily automatic update broadcasting content instructions 61xx-65xx or the weekly automatic update broadcasting content instructions 71xx-75xx in the continuous broadcasting group to realize the group music synchronous automatic update, the specific requirement of the software editing the function is that after the microcomputer reads the above-mentioned instructions in the continuous broadcasting group, the music number of the subsequent continuous broadcasting music is calculated according to the same music number variable Δ i in the formula YYh YYho + Δ i, the objective effect is that the whole group music of the continuous broadcasting group can be updated synchronously every day, the theme of the continuous broadcasting group can be kept unchanged and the music content can be updated synchronously every day or week, which is highly practical, the usage in the hall, the music of the continuous broadcasting group can be realized as if the daily music is updated automatically, the music of the continuous broadcasting group can be updated daily and the music content can be updated automatically updated every day → the same as if the music of the family dancing family can be updated once or once a day → the family is changed in the family dancing family → the family talk-talk.

The software of the embodiment also allows the user to edit the sorting simulcast instructions 81xx-85xx or the random simulcast instructions 89xx in the simulcast group, and the execution effect is that the microcomputer leaves the packet preferred simulcast state and automatically jumps into the sorting simulcast state or the random simulcast state.

The software (or subprogram) technology for the details of each function of the present invention is not complicated, and is a known technology that is known to ordinary programmers, so it is not described herein any more. The key to the success of the present invention is the flexible integration of these software, in the integration of digital instructions.
