[0002]

2. Description of the Related Art Conventionally, monitoring services exist in various fields, but such services often require a 24-hour system. There, the guards do not usually do any particular work, but are extremely inefficient and mentally complaining of sitting in front of the monitor and waiting for an anomaly to occur.

[0003] In such a monitoring operation, in the field of building security, automation such as automatically catching a sign or movement of a person with an infrared camera and alerting a security guard is proceeding. In the medical field, it is also possible to reduce the burden on healthcare workers by playing outgoing sounds in synchronization with heartbeats at the same time as monitor waveforms of the electrocardiogram system and allowing the patient's condition to be observed through the sounds. Have been done.

[0004]

[Problems to be solved by the invention]
In a plant or the like, monitoring is performed while listening to the rotating sound on the side of the line, but it is common practice to keep watching a video or waveform on a monitor in a quiet control room. Since it is difficult to keep the former for a long time, long-term monitoring such as a 24-hour system is mainly performed by the latter, so the following problems occur.

[0005] (1) Since only the visual element serves as the information source, it is easy to overlook the precursor of an abnormal situation. In particular, it is easy to overlook an abnormal phenomenon that occurs intermittently. (2) In the case of manufacturing equipment, it is also important to control the accuracy of the product.
Accuracy defects that occur during stable operation often go unnoticed unless the situation worsens considerably, and when they do, they already have a significant amount of defective products. (3) It is possible to relax by listening to the radio or listening to music during monitoring, but it is difficult to do any work with the eyes, such as reading a book or watching TV. (4) Changes in the environment, such as changes in humidity, abnormal odors, and water leaks, are not transmitted visually, despite the fact that there is information that can be experienced at the site. I do not notice.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a signal monitoring music capable of improving the monitoring accuracy and reducing the load of the visual monitoring in a visual monitoring operation. It is an object to provide a performance device.

As a specific example, in the above-mentioned visual monitoring work, the precursor of an abnormal matter that is easily overlooked or an abnormality that is easily overlooked, a poor product accuracy that occurs during the stable operation of the manufacturing apparatus, or a person who is not at the site can not understand. In addition to making it possible to reliably recognize changes in the environment and the like, it is possible to perform some other visual work while monitoring the monitor.

In the case of the above-mentioned method of emitting an oscillating sound synchronized with the heartbeat, since the outgoing sound is not preferable for non-medical workers, the present applicant has filed Japanese Patent Application No. Hei 10-494.
According to No. 94 and No. 10-295047, for the purpose of monitoring biological signals such as electrocardiograms and respiratory waves, by playing BGM (environmental music) music while synchronizing with these external signals, the biological signals can be changed through BGM. We propose a technology to notify you of a change.

[0009]

According to the present invention, in a music monitoring apparatus for signal monitoring, music data storage means for holding music data of a plurality of music pieces, and transfer from the music data storage means to a predetermined buffer memory.

Volume instructing means for performing a transposition performance of a predetermined track of the music data on the buffer memory, and setting a pitch displacement when performing transposition performance. Pitch instructing means for designating a musical instrument timbre for playing a predetermined track of the music data in the buffer memory by a set value, and an external means for simultaneously inputting one or more external signals. Link setting means for setting a link between a signal input means, each of the external signals, and one or more of the music piece indicating means, the tempo indicating means, the volume indicating means, the pitch indicating means, and the tone indicating means. Dynamic instruction changing means for changing a setting value of the instruction means to which a link with the external signal is set by the link setting means in a time series according to the signal of the external signal; Based on the set values of the tempo, the volume, the pitch displacement and the tone specified by the instruction means, the volume instruction means, the pitch instruction means and the tone color instruction means, respectively, Track playing means for giving a performance instruction to a predetermined track of the music data on the memory of the same in synchronization with a predetermined synchronization signal, and sound source means for generating an audio signal based on the instruction of the track playing means. Thereby, the above-mentioned problem has been solved.

That is, according to the present invention, a change in a monitored object can be converted into a change in music by changing a component of the music during a performance based on an external signal input from the monitored object. This makes it possible to introduce auditory monitoring into monitoring tasks that could only be done visually previously, thereby improving monitoring accuracy and reducing the load.

Specifically, the music data storage means includes:
MIDI (Musical Instrument Digital Interfac
e) When music information is provided as data, there are the following five elements that can be changed during the performance.

(1) Synchronization with tempo This is a timing signal that is indispensable for playing music, and can correspond to driving speed, heart rate, and the like. (2) Volume, intensity Operating intensity, pressure (for printing, printing pressure, ink density, etc.),
It can correspond to a scalar amount such as breathing. (3) Pitch, transposition amount It is possible to correspond to the difference amount from the target position such as operation accuracy and product accuracy (register accuracy, position accuracy, etc. in the case of printing). (4) Tone, Musical Instrument An environmental signal that fluctuates in a relatively slow cycle such as a change in ambient temperature (ink, dampening solution, temperature in dryer, etc. in the case of offset printing) is suitable. (5) Music software change This is suitable for major changes such as item switching (plate exchange for printing) or when the machine is temporarily stopped.

If the music data is an orchestral tune or the like, MIDI can independently play up to 16 tracks. Therefore, the four parameters (1) to (4) are independent for each track. Can be set. Therefore, in the case of a printing press, each printing unit can be assigned to each track. Normally, the highest tempo is common to all tracks, but if synchronized performance is performed by independent signals from each printing unit, the abnormalities between the printing units will be reflected in the disturbance of the ensemble performance. Can be immediately recognized.

As described above, since it becomes possible to introduce auditory monitoring in visual monitoring work,
The monitoring accuracy can be improved and the load of visual monitoring can be reduced.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings.

In the present embodiment, it is possible to monitor to a certain extent auditory monitoring of monitoring tasks conventionally performed visually, thereby reducing the load of visual monitoring.

More specifically, BGM (Background Music), which is recently used to improve the environment in factories and the like, is actively used, and a meaningful BGM reflecting the operation status of the line as follows. Flow.

(1) A method of appealing the characteristics of the waveform information displayed on the monitor to the auditory sense. From the waveform information displayed on the monitor, important features are modulated and transmitted to BGM. (2) Not only the operation status of the equipment, but also the accuracy and quality control of the product can be audibly controlled in the case of a manufacturing equipment.
The accuracy of the product is reflected in the musical interval so that the inaccuracy can be determined to some extent from the change in musical interval. (3) In a steady state, a regular and boring signal is generated, and since the signal is heard for a long time, the music is set to be a music that can be comfortably heard. (4) In addition to the operation status of the line, a signal from a temperature sensor, a chemical sensor, or the like is taken in, and an environmental signal is sensed and reflected in music.

In order to realize these, the aforementioned Japanese Patent Application No.
Since the two-channel (electrocardiogram and respiratory wave) signal proposed in No. 295047 is insufficient, more channels are realized. For example, in the case of a printing press, when there are many printing machines, about 12 printing units may operate in cooperation, and it is desired that a plurality of signals can be monitored independently for each unit, and further multi-channeling is required. .

FIG. 1 is a block diagram schematically showing a signal monitoring music performance apparatus according to an embodiment of the present invention.

The music video apparatus according to the present embodiment has a music data storage unit 10 for holding music data for a plurality of songs, and music data for one song transferred from the music data storage unit 10 to a predetermined buffer memory 12. And a music search section 1 for searching the music data storage section 10 for predetermined music data based on the set value of the music piece instruction section 14 and transferring the music data to the buffer memory 12.
6, a tempo instructing section 18 for designating a tempo at which a predetermined track of music data in the buffer memory 12 is played by a set value, and a volume instructing section 20 for designating a volume for playing the track by a set value. The musical instrument includes a pitch indicating section 22 for designating a pitch displacement when a track is transposed by a set value, and a tone color indicating section 24 for designating a musical instrument timbre when the track is played by a set value.

The setting values specified by the above-described instruction units have the following characteristics. The following (2) to (4) are MI
This is defined by the DI standard, and (1) and (5) are appropriately defined according to the embodiment.

(1) Tempo instructing section 18: Designates the playing time per bar in units such as msec. (2) Volume indication unit 20: 0 (silence) to be designated in 128 steps from 127 (relative volume). (3) Pitch instructing section 22: ± 127 (unit is semitone, + raises the pitch, and-lowers the pitch). (4) Tone designation section 24: The ID number of the instrument / timbre is designated by three bytes of upper bank + lower bank + program number. Each byte takes a value of 0 to 127, and is an international standard GM
In the standard, the upper bank is equal to the lower bank = 0, and the upper two bytes are a vendor extended standard. (5) Program designation section 14: Program ID

This device also has an external signal input unit 26 for simultaneously inputting one or more external signals from the monitored equipment.
And one or more of the external signals input from the input unit 26 and any one or a plurality of the tune instruction unit 14, the tempo instruction unit 18, the volume instruction unit 20, the pitch instruction unit 22, and the timbre instruction unit 24. Link setting unit 28 for setting a link with the instruction unit
A dynamic instruction changing unit 30 that changes a setting value of the instruction unit to which a link with the external signal is set by the link setting unit 28 in a time series according to the external signal;
The tempo instructing unit 18, the volume instructing unit 20, the pitch instructing unit 2
2 and the timbre designating section 24, respectively, based on the set values of the tempo, volume, pitch displacement and timbre, and while taking timing with a predetermined synchronizing signal inputted from the synchronizing input section 32, A track playing unit 34 for giving a performance instruction to a predetermined track of the music data above, and a MIDI sound source 36 for generating an audio signal based on the instruction of the track playing unit 34 are provided.

In the present embodiment, the link is set by the link setting unit 28 with the external signal and the synchronization input unit 32. For convenience, in FIG. 1, the synchronization input unit 32, the tempo instruction unit 18, the volume instruction unit 2
Only the link to 0 is shown.

The signal monitoring music performance apparatus of this embodiment will be described in detail. The signal input section 26, the tempo instructing section 18, the volume instructing section 20, and the pitch instructing section correspond to N (N> 1) tracks. N units including a unit 22, a tone specifying unit 24, a link setting unit 28, a dynamic instruction changing unit 30, a synchronization input unit 32, and a track playing unit 34 in a range surrounded by a two-dot chain line in the figure. The MIDI sound source 36 can simultaneously generate sound signals for N tracks.

The music data stored in the music data storage unit 10 is MIDI event data composed of a set of note-on and note-off commands, and the track performance unit 34 is a sequencer. The sequencer (track playing section) 34 applies a predetermined correction to the MIDI event data and outputs the MIDI event data at a predetermined timing.
Control for transferring the signal to a predetermined channel of the DI sound source 36 is performed.

Here, the MIDI event data will be described. The note-on instruction actually uses the MID
(1) status message (NOTE ON), (2) note number,
(3) An instruction in the form of velocity. In this instruction, (1) status message (NOTE O
By N), the MIDI sound source 36 detects the command of "NOTE ON" and starts preparations for producing a sound.
(2) The note number is 0 to determine the pitch of the sound.
This data is composed of 127 musical scales, and the receiving device determines which musical scale is to be produced. (3) Velocity is data representing the speed of striking a key. The data is used to determine the size. This data also has 128 levels from 0 to 127, but no sound is produced at 0. The note-off command is a command to mute the sound from the module that generated the sound by the note-on command, which is completely opposite to the note-on command. Substantially the same. However, the sound often attenuates and disappears without waiting for the note-off command, but the note-off command is essential,
A note-on command having a velocity of 0 is interpreted as a note-off command.

In this embodiment, the synchronization signal used for the performance is the external signal (for example, external signal 1 in the figure).
The sequencer 34 is an external signal such that the timing at which a note corresponding to the first beat of the bar constituting the music data is transferred is matched with each pulse of the pulse signal. Synchronous control with a signal is performed. And like this, sequencer 3
4 based on the time interval between the pulse signal whose control timing is controlled and the pulse signal immediately before it,
The dynamic instruction change unit 30 changes the set value of the tempo instruction unit 18 in accordance with the timing to control the tempo. The synchronization control and the tempo control performed here together with the volume control and the pitch control are illustrated in FIG.

At the time of performance, the time at which the first beat of the bar in the music data is played is represented by t, the set value of the tempo designating section 18 is represented by T, and the value of one bar specified in advance in the music data is represented by T. When the delta time is Δ and the total from the first beat of the bar of the delta time (d below) indicated by each note-on or note-off event is D, the sequencer 34 sets each note-on or note-off.・
By applying a correction of t + TD / Δ to the time at which the off event is transferred to the MIDI sound source 36,
Time control of a MIDI event is performed.

The time control will be described in detail with reference to the 4/4 time sheet music shown in FIG. 2A for convenience.

Assuming that the number of quarter notes per minute is M, the performance time of one note (delta time) d = 60 / M
In [sec], the performance time of one measure (delta time) Δ = 4
d. In this case, each note (1) to
The performance instruction times for (4) are as shown in FIG. 2 (B), and when these times are corrected by the tempo designation T, they become as shown in FIG. 2 (C) in the same order. That is, the total D becomes d, 2d, 3d, and 4d in order.

When the sequencer 34 transfers the MIDI event to the MIDI sound source 36, the dynamic instruction changing unit 30 outputs an external signal (for example, an external signal in the figure) input from the external signal input unit 26. The MIDI velocity control is performed by changing the set value of the volume indication section 20 based on the amplitude of 2) and simultaneously correcting the velocity parameter of the MIDI event data within a predetermined range. .

Here, the relationship between the set value and the velocity parameter will be described. Now, assuming that the set value Sv is set in percentage units, the velocity parameter values of all note events have a lower limit of 0,
Linear conversion is performed within a range of 127 as an upper limit. That is, the velocity parameter before correction is V, and the velocity parameter after correction is V
If the parameter is V ', V' = V × Sv / 100 (0 ≦ V, V ′ ≦ 12
7) If Sv = Sv = Sv
In the case of 100, V = V '(no change), in the case of Sv> 100, V'> V (strength), and in the case of Sv <100, V '<V (weak). This correction corresponds to a case where the velocity value of a note event (actually, a note-on event) corresponding to notes 4, 5, and 7 is changed from 64 to 127 in the example of FIG.

When the sequencer 34 transfers the MIDI event to the MIDI sound source 36, the dynamic instruction change unit 30 changes the set value of the pitch instruction unit 22 based on the amplitude of the external signal. , At the same time
MIDI note number control is performed by correcting the note number parameter of the DI event data within a predetermined range.

Here, the relationship between the set value and the note number parameter will be described. Now, if the set value Sn is-
Assuming that integer values of 127 to +127 are set, offsets are applied to the note number parameter values of all note events in a range where 0 is the lower limit and 127 is the upper limit (transposition in music terms). ). That is,
If the note number parameter before correction is N and the note number parameter after correction is N ', then N' = N + Sn (0≤N, N'≤127), provided that the upper and lower limits are not saturated. , Sn =
In the case of 0, N '= N (no change), in the case of Sn> 0, N'> N (high), and in the case of Sn <0, N '<N (low). This correction is performed in the example of FIG.
This corresponds to the note number values of note events (actually, note-on and note-off events) corresponding to notes after the sixth note being uniformly increased by +2 (transposition for all notes).

When the dynamic instruction changing section 30 changes the set value of the tone color indicating section 24 based on the amplitude of the external signal, the sequencer 34 sends the next MIDI event to the MIDI sound source 36. The MIDI program control is performed by transferring a MIDI setting command for changing the program number to the set value to the MIDI sound source 34 before transferring the program to the MIDI sound source 34.

Further, when the dynamic instruction change unit 30 changes the set value of the music piece instruction unit 14 based on the amplitude of the external signal, the sequencer 34
The MIDI control command for resetting the I event is transferred to the MIDI sound source 36, and the music search unit 16 transfers predetermined music data based on the set value from the music data storage unit 10 to the buffer memory 12, and When the sequencer 32 starts playing from an initial state, the music tune is changed.

FIG. 3 shows an example of correction of MIDI event data by the music performance device of the present embodiment. This figure shows MIDI event data consisting of messages arranged in the order of delta time, status, note number, and velocity for notes 1 to 10.

In the example of the top of the data before correction shown on the left side, after the lapse of time 0, 3-byte data (note event) of “90.60.64” is stored in the MIDI sound source 3.
Sent to 6. Here, only status message 1
It is described in hexadecimal, with note-on being "90" and note-off being "80". However, note number "60" is difficult to understand, so "C"
3 "(the sound of C or C in the third octave) is also displayed. When MIDI data is recorded in a disk file or the like, an event occurrence time is also required.
Delta time information is also added in a format called MF (Standard MIDI File).

As shown in FIG. 3, in the present embodiment, a modulation (correction) instruction as shown below the arrow is given to the data on the left based on a change in the input external signal. If so, the right data modulated according to this instruction is played.

Therefore, when the performance apparatus of the present embodiment is applied to process monitoring by a BGM in a production line or the like in a manufacturing industry, the music data storage unit 10 is conceptually shown in FIG. MIDI stored in
Synchronization, volume and pitch are input as external signals to the BGM data of the jukebox shown in the upper part corresponding to the event data by the MIDI modulator shown in the middle corresponding to the track processing unit shown in FIG. Correction based on each signal of driving speed, driving intensity, driving error, and correction (modulation) to reflect these information
By doing so, it is possible to perform as BGM data as shown in the lower part. By utilizing the principle of such process monitoring, it is possible to convert the signal of every work site into comfortable music and to use the monitoring by hearing.

FIG. 5 shows B which can be applied to such a purpose.
The image of the process monitoring concept by GM was shown. In this figure, [Music conversion engine] corresponds to the track processing unit shown in FIG. 1 composed of more than the number of input external signals, analog electric signals input from the equipment to be monitored as external signals, measurement Digital signal from the detector, detection signal detected by the power noise detector from the power / signal system, noise / vibration, radio wave / radiation, and harmful gas detected respectively by microphones, electromagnetic wave detectors, and chemical sensors that are offline sensors Each monitoring signal is input to the music conversion engine as an external signal.

In this music conversion engine, BGM data created by MIDI data is subjected to MIDI modulation based on these external signals, and is transmitted as a MIDI code to a MIDI sound source 36, whereby an amplifier 38 and speaker It is output as music after modulation (correction) via 40.

Each data of data display and waveform display based on each external signal inputted to the music conversion engine can be displayed on the display 42.

Note that MIDI encoding can be used to create MIDI-format BGM data stored in the music data storage unit 10. This MIDI encoding is disclosed by the present inventors in JP-A-10-247099 and JP-A-11-9-9.
No. 5753, which is a new audio coding technology, which decomposes an audio signal recorded as waveform information into a set of musical notes defined by attributes such as pitch, length, and intensity. It is recorded with a code. With this technology, MIDI data can be automatically created from recorded material even for BGM without MIDI data.
In particular, Japanese Patent Application Laid-Open No. H11-95753 proposes a technique for converting BGM including vocals, which has been said to be impossible to be represented by MIDI data, into MIDI data, and applying the technique to the MIDI modulation of the present invention. Can be.

In the present embodiment described in detail above, various performance parameters of music are controlled by a plurality of external signals, and the application is expanded from the medical field for which application has been filed, and the production line of the manufacturing industry is expanded. It can be applied to a wide range of signal monitoring fields that can be monitored by periodic operation signals such as monitoring.

For example, as shown in FIG. 4, a desired music is played while tuning the operation speed of the monitored equipment to the music tempo, the operation intensity to the music intensity, and the operation error to the music interval. . Then, it is possible to change the musical instrument to be played due to a change in the environment or to change the music software based on the item switching. Therefore, a maximum of 4 channels of signals can be accepted for each item, and music can be assigned to one instrument.
Up to six parts can be played at the same time, so if the object to be monitored is divided into a plurality of units and operating in cooperation, up to 16 units of equipment can be monitored at the same time, and theoretically 16 × 4 channel signals Can be monitored by one set of music performance devices.

According to the present embodiment described in detail above, the BGM
In addition to the general effect of relieving the mental tension, the effect of notifying the operating state of the equipment and the condition of the patient can be obtained by flowing the information to the work site, the control room, the office, or the like.

Further, it is not necessary to stare at the monitor as in the prior art, and it is possible to perform some work, reading, and the like during the monitoring. Until now, it is possible to monitor environmental changes and braking failures that could not be understood unless they were on the side of the line, in a quiet separate room, so that it is possible to prevent a large amount of failures and serious accidents from occurring Become like

Although the present invention has been specifically described above, the present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist thereof.

For example, the signal monitoring music performance device according to the present invention is not limited to the one described in the above embodiment.

The music data is not limited to the MIDI event data. For example, the ringtone melody (so-called “ringtone”) recently used in mobile phones, PHSs, and pagers has a simplified description format for MIDI event data, which is an international standard, so that beginners can easily enter it. Furthermore, there is a difference in the description format depending on the maker / model. However, since the basic form is the same as that of MIDI only by simply expressing the note information, the present invention can be applied to the present invention. In particular, if the present invention is applied to a mobile phone, a new merit that monitoring can be performed in a mobile environment at a remote place from the site is also provided.

In the above-described embodiment, the case where the synchronization signal is extracted from one of the external signals by the synchronization input unit has been described. However, the present invention is not limited to this. You may make it play with a clock. Also, as described above, one beat and pulse of a bar are 1
It is not necessary to have a one-to-one correspondence, and synchronization control that takes a timing every plural pulses may be performed.
