Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an operation notification device, and in particular sends an operation signal from a detector provided on a child device located far away to a central parent device. The present invention relates to an operation notification device for confirming the operation and notifying the operation using information processing means provided in the machine.

[Conventional technology]

For example, in large buildings, temperature detectors, smoke detectors, door opening/closing detectors, passage detectors, etc. are installed in each room, hallway, stairway entrance, etc. in case of abnormal situations such as theft or fire at night. A slave unit equipped with a transmitter, etc. that transmits the operation signal of the detector and its detector to the central monitoring side is placed, while a master unit is placed on the central monitoring side, and the operation signal from the slave unit is transmitted wirelessly or by wire. The system receives the signal, determines from which handset the signal was sent, and notifies staff of the location where the abnormal situation has occurred.

In addition, a master unit is installed at the fire department, and a slave unit consisting of a detector to detect the occurrence of a fire and a transmitter to receive the operating signal is installed in each home. The system identifies the location of the fire and alerts police personnel to the location of the fire.

Furthermore, in each home, slave units consisting of designated detectors, transmitters, etc. are placed at entrances, windows, bathrooms, etc., while base units are placed in places where people are always present. The base unit receives the signal from the machine, identifies which slave unit the signal came from, and reports it, allowing you to immediately know where and what is happening.

When the detector installed on each slave unit operates in this way, the operation signal is sent to the base unit, and the base unit uses an information processing device such as a microcomputer installed in the base unit to determine how the signal is processed. Conventionally, an oscillator was provided for each slave unit in order to determine whether the message was sent from a slave unit and to notify the slave unit that the detector was activated, and the output of the oscillator was used to send signals to speakers and indicator lights. etc., to notify the operation of the handset.

[Problem that the invention seeks to solve]

In this way, in the conventional device, in order to operate the operation notification means, an oscillator corresponding to each slave unit was provided in the base unit, so the configuration of the base unit was complicated.
This method has the drawbacks of being expensive and requiring a large device.

[Means for solving problems]

More specifically, it consists of a handset equipped with a detection means for detecting a predetermined state change, and a base machine equipped with an information processing means and an operation notification means having an internal storage means, and the base machine In the operation notification device for identifying the operation state and notifying the operation, the storage means stores steps for turning on the operation notification means and steps for turning off the operation notification means, which are executed one step at a time in synchronization with a predetermined clock. A cyclic program consisting of a plurality of program steps is stored in each slave device, and the number of program steps from the step of turning on the operation notification means to the step of turning off the operation notification means and the number of program steps for turning off the operation notification means.

The feature is that each handset operates at a different frequency.

〔Example〕

Hereinafter, an example in which the operation notification device of the present invention is applied to the case where the operation status of four slave devices is identified and the operation notification is performed will be described with reference to FIGS. 1 to 7.

In Figure 1, S ₁ to _{S 4} are slave units, and each slave unit is
A state detector 1 serves as a detection means for detecting a predetermined state change such as a temperature detector, a smoke detector, a door opening/closing detector, a passing detector, etc. When the state detector 1 operates, the frequency peculiar to the slave unit is detected. It is composed of a pulse generator 2 that generates a pulse signal f _s , a carrier wave f _c generator 3 for transmitting the pulse signal to the base unit S ₀ , a transmitter 4 , and a transmitting antenna 5 .

On the other hand, the base unit includes a reception antenna 6, a receiver 7, a slave unit identification number setting section 9, a reference time signal generation section 10, an information processing section 11 as an information processing means having a storage means inside a microcomputer, etc., and an operation notification. The signal processing device 8 includes an operation notification section 12 as a means.

The receiver 7 further includes an amplification unit 71 that amplifies the received signal f _c +f _s , a detection unit 72 that separates and extracts a pulse signal f _s specific to the slave device from the amplified signal, and further converts the signal into a waveform. Shaped into a pulse signal f _s specific to the handset
It consists of a waveform shaping section 73 that restores the waveform.

Furthermore, a more specific configuration of each part within the signal processing device 8 is as shown in FIG.

That is, 9 is a handset identification number setting section, and a series circuit of a diode D and a switch SW is connected to each microcomputer intersection as shown in FIG. 2b. To set the identification number in the handset identification number setting section 9, the identification number is set in binary coded decimal notation by, for example, using two horizontal lines and turning on switches at predetermined positions in the second and first digits. For example, the slave devices S ₁ , S ₂ ... each send pulse signals f _s1 , f _c2 ... at frequencies of about 50 pulses, 70 pulses, ... during the reference time T when the reference time signal a is in the "1" state. If this occurs, each row direction setter of the setting unit 9 will have 〓 ₁ = 50,
Set 〓 ₂ = 70... in a 4-bit binary coded base of 10 system (the 〓 mark in the diagram indicates the state in which the switch SW is turned on).

In this case, it goes without saying that the setting value can be set using three digits, or even four digits, depending on the size of the setting numerical value.

Reference numeral 10 denotes a reference time signal generator, which generates a signal a that continues to output "1" for a reference time T in a constant time period _T0 .
occurs.

The microcomputer 11 is composed of a central processing unit (CPU) 13, a random access memory (RAM) 14, a read only memory (ROM) 15, and a clock pulse generator 16.

Each command is executed by a clock pulse generator 1 based on a program stored in a read-only memory (ROM) 15 as a program storage means.
The central processing unit (CPU) is clocked from 6 to C _p .
13 to each input/output device and a random access memory (RAM) 14 serving as an information storage means.

17 is a decoder and central processing unit (CPU) 13
Based on the signal from the slave unit, the output is given to the sound generation unit 18 and the display unit 19 so that the sound generation unit 18 generates an alarm sound specific to the slave unit, while display units 19-1 to 19-4 display the operating status of the slave unit. Among them, a predetermined display device is driven.

The operation of the device configured in this way is further explained in the third section.
Flowcharts in Figures 6a and 6b, Figure 6c
This will be explained using the waveform of FIG. 7 and a diagram showing the memory contents in the random access memory 14 in FIG.

The memory in the random access memory (RAM) 14 has a binary coded decimal structure of 4 bits per word. In the following description, random access memory is referred to as RAM, read-only memory as ROM, central processing unit as CPU, accumulator in CPU as Acc, and memory locations such as address 0 and A in RAM. is expressed as M0, MA, etc., and its contents are written in brackets [Acc], [M0], [MA].
etc.

Before explaining the details of the operation, the outline will first be explained.

According to the program shown in Figure 3, first set the identification number setting value of each handset in the handset identification number setting section.
Store it in a predetermined memory location in the RAM 14, and then calculate the number of pulses from the slave unit captured within the reference time T.
Store in RAM14. This result corresponds to storing the pulse frequency being sent from the slave device to the master device in the RAM 14.

The pulse frequency stored in the RAM 14 is then subjected to approximation processing, for example, rounding off, according to the program shown in FIG. The reason for performing this approximation process is to remove the effects of fluctuations in the oscillation frequency of the oscillator installed on the slave unit or noise pulses during transmission, and to ensure that the operation of the slave unit can be confirmed within the base unit. be. That is, this is to absorb some variation in the input pulse frequency and compare it with the slave device identification number setting value.

If such a comparison is repeated, for example, four times for pulses input at different times, and the result matches the predetermined number of handset identifications set in the setting section 9, the program shown in FIG. , After determining which handset should be notified of the operation, the sixth
Operation notification is executed using the programs shown in Figures a and b.

The details will be explained below.

When the status detector ₁ provided in the slave unit S ₁ in FIG.
Pulse signal f _s1 generated at a rate of 50 pulses within
is generated, and the transport generator 3 operates. In the transmitter 4, a signal obtained by modulating the pulse signal f _s1 with a carrier wave f _c is transmitted from the antenna 5 toward the base unit S ₀ .

The base unit S ₀ receives the radio waves transmitted from the slave unit S ₁ using the antenna 6, and the receiver 7 performs processing such as amplification, detection, and waveform shaping to generate pulses generated by the slave unit S ₁ . Restore the signal f _s1 and take it out.

Next, this pulse signal f _s1 is input to the signal processing device 8 provided in the base unit S ₀ .

As shown in FIG. 2, the pulse signal _fs1 input to the signal processing device 8 is sent to the central processing unit ₁₃ together with the reference time signal a generated at a constant period _T0 from the reference time signal generator 10 via the diode D1. , and the reference time signal a is in the "1" state.
The number of pulses extracted during the time is determined by the central processing unit 13 based on the program instruction from the ROM 15.
It is stored in a predetermined location in the RAM 14.

In other words, first, when you manually turn on the power of the main unit S ₀ ,
The program instructions shown in FIG. 3 contained in the ROM 15 are sequentially executed in synchronization with the clock from the clock pulse generator 16. Based on the instruction, all memory contents of the RAM 14 are reset in step 20. Next, in step 21, the handset identification number setting unit 9 sets the setting values 〓 ₁ to 〓 ₄ , for example 50; (digit); 2nd address and 3rd address; ... are sequentially stored in storage locations M0 and M1; M2 and M3...

Reference numeral 22 denotes a program connector, which has no meaning as a program command, but is a symbol provided for linking with a program to be described later.

Next, in step 23, it is determined whether the reference time signal a from the reference time signal generator 10 is in the "1" output state.

If the reference time signal a is in the "1" output state, it is determined in the next step 24 whether or not there is a pulse signal sent from the slave device. If not, return to step 23 and repeat the same program steps. At this time, the pulse signal f _s1 from slave unit S ₁
is taken out into the main unit, its pulse 1
The slave unit S ₁ pulse storage location MA consists of address A (1st digit) and address B (2nd digit) of RAM 14,
Store in MB. After reading one input pulse signal, the program returns to the program connector 22, executes program steps 23 to 25 again, and reads the next input pulse. This operation continues while the reference time signal a is in the "1" state. As a result, A and B address memory locations
The number of pulses input while the reference time signal a is in the "1" state is stored in MA and MB in binary coded decimal notation. For example, if the number of input pulses at this time is 53 pulses, the memory location MA at address A will contain "0011" from the upper bit to the lower bit, and the memory location at address B will contain "0011" from the upper bit to the lower bit.
Similarly, "0101" is stored in the MB from the upper bit to the lower bit.

When the reference time signal a becomes "0", step 23
The judgment result in step 2 is NO, and the process branches to step 26.

Step 26 is the address C memory location MC of RAM14.
Determine whether there is a count flag.

This count flag is set and reset in the program steps described below.

If there is no count flag in the C address memory location MC, the process moves to the program connector 27.

In program step 29 of FIG. 4, the first digit value [MA] stored at address A among the pulses emitted from the handset and taken out within the reference time T is read out to Acc.

It is determined in step 30 whether this content is smaller than 4.

If the judgment result is YES in step 30, step
At 32, set [Acc] to 0 and store this in MA.

If the judgment result is NO, in step 31, [Acc] is set to 0 and stored in MA, and 1 is added to [MB], and the value is newly stored in MB.

As a result, the number of input pulses from the slave unit stored in MA and MB is rounded off and the values are newly input into MA and MB. That is, approximation processing is performed.

Next, in step 33, enter the second digit value [M1] of the setting value corresponding to slave unit _S1 set in the parent unit.
Read to Acc. This value [Acc] is 2 times the number of approximated input pulses stored in MA and MB.
Subtract from the digit value [MB] and put the difference in Acc.

In step 34, it is determined whether [Acc] is 0 or not. That is, in order to identify which slave unit is in the operating state, it is determined whether the second digit of the setting value corresponding to slave unit _S1 matches the second digit of the input pulse number approximate value. If YES, proceed to step 35; if NO, proceed to step 39.

In step 35, the memory contents at address 10 [M10] are set to 1.
is added and stored in M10, and taken out to Acc, and in step 36 it is determined whether the value has become 4 or not. That is, the match determination at step 34 is performed four times, and it is determined whether or not there is a match all four times. If the result is YES, in step 37 the D address memory location MD is
1 is set to indicate the operation of the slave unit _S1 , 1 is set to the C address memory location MC, a count flag is set to indicate that there has been a match four times, and the process moves to the program connector 28. On the other hand, in the case of NO, the process directly moves to the program connector 28.

By the way, if the judgment result in step 34 is NO, the process moves to step 39, this time the memory contents of M3 [M3] are read into Acc, the difference between it and [MB] is stored in Acc, and in step 40, [Acc] is Determine whether it is 0 or not. That is, this time it is determined whether or not the setting value corresponding to slave unit _S2 matches the input pulse number approximate value.

If the result of the judgment is YES, then in step 41 the matching circuit is stored in the memory location at address 11, and at the same time it is taken out to Acc, and in step 42 it is judged whether the value has become 4 or not. That is, the match determination at step 40 is performed four times, and it is determined whether or not there is a match all four times. If the result is YES, then in step 43, the D address memory location MD is set to 2 to display the operation of slave unit S ₂ , MC is set to 1, and a count is set to indicate that there has been a match four times. A flag is set and the process moves to the program connector 28.
On the other hand, if NO, program connector 2 is
Move to 8.

However, if it is determined NO in step 40, a program similar to the above program that identifies a series of slave units is executed to determine the approximate value of the input pulse number to be the set number corresponding to slave units S ₃ and S ₄ . Determine whether 〓 ₃ , 〓 ₄ match or not, and if they match, 12
Add 1 to the memory contents of addresses 13 and 13 [M12] and [M13], and when the number reaches 4, each slave unit S ₃ and S ₄
The codes 3 and 4 representing 0 are set in the D address memory location MD, and the count flag MC is set to 1, and the program is transferred to the program connector 28. Furthermore, if the input pulse signal is not determined to have been emitted from the slave units S ₃ and S ₄ , the program connector 22
Return to

Execute the above program with an information processing means,
As a result of approximating the number of pulses taken into the central processing unit 13 within each reference time T, if they match four times as one of the slave unit identification number setting values set in the base unit, identification is performed based on the result. The operation of the slave unit is notified. The program for this purpose is the program shown in Figures 5 and 6 a and b, and in Figure 5 it is a program for selecting what kind of notification operation to perform in response to the identified event. . Further, FIGS. 6a and 6b show an example of the notification operation program selected in FIG. 5. For example, the pulse input to the master unit is from slave unit _S1 , and as a result of executing the program shown in Figure 4, if the pulse progresses from step 34 through steps 35 to 37 to connector 28, MD will contain 1. Since the program is stored, when the program shown in FIG. 5 is entered, the determination result in step 44 becomes YES, and the program linker 45 is entered to execute the notification operation program shown in FIGS. 6a and 6b.

That is, in step 52 of FIG. 6a, "1" representing a pronunciation mark is set in the fourth bit of MD. In the case of this embodiment, the number of handsets is four, so numbers are assigned corresponding to these handsets, and the number of identified handsets is determined by MD.
If set to , only 3 bits are used at most,
Since the 4th bit is empty, this bit is used to set the pronunciation mark, and there is no reason why it must be stored at the same location as the number of handset identification numbers.

As a result of setting the pronunciation mark in step 52, the memory content of the MD becomes "1001".

This stored content [MD] is extracted to Acc in step 53, and is outputted to the operation notification section 12 in step 54.

The operation notification unit 12 outputs a predetermined display lamp via the decoder 17, in this case the display lamp 19-1.
At the same time, the driving voltage of the speaker 18 is turned on. Next, in step 55, the contents of address 15 [M15] (value at this time is 0) are taken out to Acc, and 1 is added to the contents.

The memory locations M15 to M18 of the RAM 14 are provided to store the number of generation of sound pulses, as will become clear from the description below. M15 is the first digit, M16 is the second digit, and M17 is the first digit. is the third digit, M18
The fourth digit is stored, and the operation notification is configured to end when a predetermined number of sounding pulses have been generated, for example, 10,000 in this embodiment.

In step 56, the result of adding 1 to [M15] is 10.
If it has not reached 10, the result of adding 1 in step 56 is stored in M15 in step 57, and the sounding pulse is turned off in step 58. When the sound generation pulse is turned off, the driving voltage of the speaker 18 is turned off. After executing step 58, return to step 52 again and [M15] becomes 9.
Steps 52 to 58 are cycled until .

As a result, as shown in FIG. 6c, the speaker drive voltage is turned on at step 54, this on state continues until step 58, and when it is turned off at step 58, the sound generation pulse continues until the off state returns to step 54. Generate P.

By the way, each of the above-mentioned steps actually consists of a plurality of steps, for example, steps 54 to 58.
and steps 58 to 54 each consist of 14 steps. The pulse generator 16 performs these steps.
When executed in synchronization with, for example, a 50 KHz clock extracted from the information processing means, a sounding pulse having an audio frequency of about 1.8 KHz, which is the output of the information processing means, will be applied to the speaker 18.

In this way, by cycling through the cyclic program consisting of steps 52 to 58, sounding pulses P are generated, and the number of occurrences is sequentially stored in M15, and when the 10th sounding pulse P is generated, step 55 Therefore, [Acc] = 10, so step 56
If the judgment result is NO, the process moves to step 59. In step 59, set [Acc] to 0 and
By putting it in M15, pay [M15] to 0. Next, in step 60, set [M16] (value at this time is 0).
After taking it out and adding 1 to Acc, the sounding pulse is stopped in step 61. At step 62, [Acc] is 10.
, that is, the number of occurrences of the sounding pulse P.
It is determined whether or not the number of times has reached 100. If the number has not been reached, [Acc] is stored in M16 at step 62' and the process returns to step 52. Returning to step 52, the above-described circulation program is cycled again. From step 56 to step 59 when the number of generation pulses reaches 10
The program moves to step 62 via step 61, and repeats the program from step 62 to return to step 52. At this time, the process goes from step 54 to step 56 to step 61.
The actual number of steps from step 54 to
Keep the number of steps the same as up to 58. Eventually, when the number of generation pulses reaches 100, the program transitions to the program shown in FIG. 6b via the program connector 63.

At step 64 in Figure 6b, set [M16] to 0, and at step 65, move to the third digit memory location.
Take out [M17] from M17 and add 1 to Acc, and it is determined in step 66 whether the result reaches 10 or not. That is, in step 66, the number of generation pulses is
It is determined whether the pulse signal has reached 1000 or not. If it has not reached 1000, it is checked in step 67 via step 66' whether or not the pulse signal from another slave unit is being input to the base unit. If a pulse signal from a slave unit is input and has a higher priority than the operation notification of the slave unit, the count flag is reset and the program returns to the program shown in FIG. 3 via the program connector 22. However, if there is no signal input from another handset, or if there is signal input but the priority is lower than that of the handset that is currently notifying the operation, the program immediately returns to step 26 even if the program in Figure 3 is returned. Via the program connector 28, the program returns via program steps 44 and 45 of FIG. 5 to program step 52 of FIG. 6a. As a result, the sounding pulses P are generated without interruption.

This operation can be carried out by increasing the number of times the sounding pulse P is generated.
It is executed repeatedly every time it reaches 100, and eventually reaches 1000.
When this is reached, the determination result at step 66 becomes NO, and the process moves to step 68.

At step 68, pay [M17] to 0 and step
At 69, take out the 4th digit [M18] to Acc and add 1 to it.
Step 70 to see if the result reaches 10
Judge by.

If the number of occurrences of the sound pulse P does not reach 10,000 and the judgment result in step 70 is YES, in step 70' the [Acc] at this time is stored in M18, and then step
67, the process for the signal input from the other handset described above is executed, and the process returns to the program shown in FIG.

In this way, the number of times the sound pulse P is generated is 10,000.
When reaching the specified number of sounding pulses, the generation of the specified number of sounding pulses is completed, and in order to end the operation notification of the slave unit in step 71, after resetting all [M10] to [M13], [MC] and [MD], step 67 is executed. After that, the program returns to step 23 in FIG. 3 and prepares for the next operation notification.

As described above, by executing the circulation program shown in FIG. A predetermined operation notification sound is generated.

That is, the sound generation pulse P in the above explanation and in FIG.
As is clear from the waveform diagram, the on-time of the sounding pulse P, that is, the on-time of the speaker drive voltage, mainly depends on the time τ1 required to execute the steps from program step 54 to step 58 and the time _τ1 required to execute the steps from step 54 to step 61. The off _- time of the pulse P, that is, the off-time of the speaker driving voltage, is determined mainly by the time _τ2 required to execute each step from step 58 to step 54 and step 61. The time required to execute each step from step 54 to step 54 is determined by τ ₂₀ . Therefore, if the number of steps executed during the on-time and off-time of the speaker drive voltage is made approximately equal so that τ ₁ ≒τ ₁₀ and τ ₂ ≒τ ₂₀ , a sounding pulse of approximately constant frequency can be obtained. In other words, the stop time of the sounding pulses generated every 100 times τ ₃
is a little longer because it reaches step 54 through steps 62, 66, 67, 23, 28, 44, 45, etc., and the stop time τ ₄ of the sounding pulse that occurs every 1000 times is longer than step 54.
62, 66, 70, 67, 23, 28, 44, 45, etc. to reach step 54, which makes it a little longer, but since the number of times these pulses occur is small, overall, the sound frequency is considered to be almost constant.

In this way, the operation notification to the slave unit _S1 can be made by directly driving the speaker based on the program shown in FIGS. 6a and 6b to generate a predetermined notification sound. Furthermore, the number of program steps from the step of turning on the operation notification means to _the step of turning it off, and the step of turning the operation notification means from the step of turning it off to _the step of turning it on _, are similarly applied to the other slave units S 2 , S 3 , and S 4 . To make the number of program steps different for each handset, you can change the number of steps that determine the start and stop of the sound pulse by inserting empty steps in the middle. If the program connectors 47 to 51 shown in FIG. 5 are followed by the program connectors 47 to 51 of FIG. 5, notification sounds with different pitches can be generated in response to the operation notification of each slave unit.

Note that the sound pulses obtained for each slave unit in this way not only drive the speaker, but also drive the display lamp, and the display lamp provided corresponding to each slave unit can be set to a frequency specific to that slave unit. You can also make it frizz.

In addition, in the above embodiment, in order to identify the operation of the slave unit by the base unit, the slave unit generates a pulse with a frequency unique to the slave unit, which is received by the base unit, and if the pulse is taken out within the reference time. Although the number of pulses is processed by the programs shown in FIGS. 3 and 4 to identify the operating slave unit, this is just an example, and the present invention is not limited to this. A frequency signal unique to the slave unit sent from the slave unit is identified by a filter, or a coded pulse unique to the slave unit is sent from the slave unit, and the base unit identifies the slave unit according to the code. The handset identification means can be arbitrarily designed.

Moreover, each of the programs described above is merely an example, and it goes without saying that the programs can be arbitrarily modified without departing from the scope of the claims.

As described above, according to the present invention, the handset is comprised of a slave device equipped with a detection means for detecting a predetermined state change, and a base device equipped with an information processing means and an operation notification means having an internal storage means, In the operation notification device for identifying the operation state of the handset side in the base unit and notifying the operation, the steps for turning on the operation notification means, which are executed one step at a time in synchronization with a predetermined clock, are stored in the storage means. A cyclic program consisting of a plurality of program steps including a step for turning off the operation notification means is stored in each of the slave devices, and the number of program steps from the step for turning on the operation notification means to the step for turning off the operation notification means. and the number of program steps from the step of turning off the operation notification means to the step of turning on the operation notification means is different for each of the circulation programs, and the information processing means determines the operation state of the slave device. At the same time, the circulating program corresponding to the identified slave device is executed a predetermined number of times, the output of the information processing means is supplied to the operation notification means, and the operation notification means is operated at a different frequency for each of the slave devices. Therefore, in order to identify the slave unit whose detector has activated in the information processing equipment, and at the same time to notify the operation of each slave unit, a special frequency signal is sent to each slave unit outside the information processing equipment. It is possible to directly drive operation notification means such as a speaker from the information processing device at a frequency corresponding to each child device without providing different oscillation means.
