There is.

The transmitting antenna 15 is provided in the storage box 8
It is arranged at the bottom of the box body 8a and is adapted to collectively transmit radio signals to a plurality of timer alarm devices 1 housed in the box body 8a which is a predetermined area.

Further, all of the various devices constituting the timer alarm device 1 described above are housed inside the tag unit 3.

Next, the operation of this embodiment will be described with reference to FIGS. 2 and 3. Multiple timer alarm devices 1
Are stored in advance in the storage box 8 of the alarm setting device 7, as shown in FIG. In FIG. 2 showing a flow chart of the control contents of the control device 11, first, in the judgment step A1 of “Is the set time input?”, The control device 11 is, for example, by the tour attendant before the start of the free action. When the input of the set time, which is the time when the alarm is generated by the operation of 9a, is input, and the input of the set time is received and the determination is “YES”,
The process moves to the processing step A2 of "reading the current time".
In this case, the set time is set to the free action set time or a time slightly before the set time.

In processing step A2, the controller 11
When the current time is read from the clock 13, the process proceeds to the next "calculation of set time" processing step A3. In processing step A3, the control device 11 calculates the set time by subtracting the current time read in step A2 from the set time input in step A1. Then, the process proceeds to the "signal transmission" processing step A4.

In processing step A4, the controller 11
Reads out an identification code unique to the alarm setting device 7 stored in advance in the storage device 12, uses it as an identification code signal, and uses a set time as a display signal and a set time as a set time signal. The signal of the transmitter 14
By outputting the signal to the timer alarm device 1 in the storage box 8 as a radio signal from the transmitting antenna 15.

The operation of the timer alarm device 1 will be described with reference to FIG. In FIG. 3 showing a flow chart of the control contents of the control device 16, first, in the judgment step B1 of “reception signal is present?”, The control device 16 receives the signal transmitted from the alarm setting device 7 (step A4). When the identification code, the display and the set time signal are received, the process proceeds to the processing step B2 of "set identification code in storage device". In the processing step B2, the control device 16 writes and stores the received identification code of the alarm setting device 7 in the storage device 19, and then the processing step B of "set a timer to set time"
Move to 3.

In process step B3, the controller 16
Writes the received set time in the timer device 20 and sets the set time, and causes the timer device 20 to start the time counting operation (countdown). Then, the processing step B4 of the "display signal output" is performed.
Move to Then, in processing step B4, when the control device 16 outputs the received display signal of the set time to the liquid crystal panel 4 to display it, the control device 16 proceeds to processing step B5 of "calculate pre-bell time".

In process step B5, the controller 16
Sets a predetermined time before the set time, for example, 20% before the set time as the pre-bell time (for example, the set time 6
12 minutes before 0 minute), the set time transmitted from the alarm setting device 7 is multiplied by 0.2 to be subtracted from the set time, and the calculated value is written and stored in the storage device 19.

The above-mentioned processing is performed in a state where a plurality of timer alarm devices 1 are housed in the alarm setting device 7. After that, one timer alarm device 1 is taken out from the storage box 8 of the alarm setting device 7 for each passenger on the bus, and each passenger is allowed to take free action. At this time, each passenger acts by attaching the timer alarm device 1 to clothes or the like by the safety pin 5 or the clip 6 provided on the batch body 2 of the timer alarm device 1.

In the following, processing will be described on the assumption that the passengers return to the bus after completing their free activities. again,
Referring to FIG. 2, the control device 11 of the alarm setting device 7
Shifts to step A5 of "whether the alarm release time has passed?" After step A4. Here, the alarm release time is set uniformly as, for example, 5 minutes before the set time, or as in step B5, for example, 20% of the set time is subtracted from the set time.
Set before the set time.

At the judgment step A5, the controller 11
Reads the current time from the clock 13 to determine whether or not the alarm release time set as described above has passed. When the control device 11 determines “NO” at the determination step A5 that the alarm release time has not passed, the control device 11 proceeds to processing step A6 of “transmission of identification signal”.

When the control device 11 outputs the identification code of the alarm setting device 7 to the transmission device 14 and causes the transmission antenna 15 to transmit the identification code in the processing step A6, the control device 11 outputs the identification code.
5, the identification code signal is continuously transmitted until the set time elapses in step A5. Then, in step A5, when the set time has elapsed, the control device 11 causes “Y
When it is determined to be "ES", the process proceeds to processing step A7 of "transmit identification code signal and alarm release signal".

In processing step A7, the controller 11
Is an identification code signal and an alarm release signal (release signal)
Is transmitted to the transmitting device 14 and transmitted from the transmitting antenna 15, the process proceeds to the judgment step A8 of "Is the end switch pressed?" In the judgment step A8, the control device 11 judges whether or not the "end" switch of the input device 9a is turned on, and if the "end" switch is not turned on and "NO", the control device 11 proceeds to step A7. . Further, in the judgment step A8, if the end switch of the input device 9a is turned on and the control device 11 judges "YES", the process is ended.

Referring again to FIG. 3, the control device 16 of the timer alarm device 1 proceeds to the judgment step B6 of "Is there a received signal?" After step B5. In the determination step B6, the control device 16 causes the passengers who have finished their free movement to return to the bus, the timer alarm device 1 is returned and stored in the storage box 8 of the alarm setting device 7, and a signal is transmitted from the alarm setting device 7. Wait for In the decision step B6, if the passenger is still freely moving and no signal is received and the control device 16 decides "NO", the process proceeds to decision step B7 of "is it pre-bell time?".

At the decision step B7, the controller 16
Reads the time during the time counting operation of the timer device 20 and determines whether or not the pre-bell time calculated in step B5 has been reached. In the determination step B7, the timer device 20
Time has not reached the pre-bell time, the control device 16
If it is determined to be "O", the process proceeds to determination step B8 of "is the remaining time of the timer 0?" At decision step B8,
The control device 16 determines whether or not the time of the timer device 20 read in step B7 is “0”, and when the control device 16 determines that the time is not “0” and “NO”, the process proceeds to step B6. Transition.

The above loop of steps B6.fwdarw.B7.fwdarw.B8.fwdarw. Is repeated until a signal is transmitted from the alarm setting device 7 at step B6 or the time of the timer device 20 reaches the pre-bell time at step B7.
Next, the following cases will be described separately.

(1) When the passenger returns to the bus and returns the timer alarm device 1 to the storage box 8 of the alarm setting device 7 before the pre-bell time is reached In this case, the control device 11 of the alarm setting device 7 Until the set time elapses, the loop of steps A5 and A6 is repeated and the identification code signal is continuously transmitted. Therefore, the control device 16 of the timer alarm device 1 determines “YES” in step B6. , "Does the identification code match?", And proceeds to a judgment step B9.

At decision step B9, the controller 16
Reads the identification code of the alarm setting device 7 stored in the storage device 19 and compares it with the received identification code.
Then, the two match, and the control device 16 displays "YE
If it is determined to be "S", the process proceeds to a determination step B10 of "is it an alarm release signal?" In the judgment step B10, the control device 16 judges whether or not the received signal is the alarm cancellation signal, but since the alarm cancellation signal is not transmitted until the alarm cancellation time set on the alarm setting device 7 side has passed, "NO". ", And the process proceeds to step B6.

That is, the control device 16 repeats the loop of steps B6 → B9 → B10 until the alarm cancellation time has elapsed. Then, when the alarm release time has elapsed, the control device 11 of the alarm setting device 7 proceeds to step A
Since the alarm cancellation signal is transmitted in step 7, the control device 16 of the timer alarm device 1 determines "YES" in step B10, and proceeds to processing step B11 of "stop clocking and alarm operation".

In process step B11, the control device 16 stops the time counting operation of the timer device 20 and the alarm operation. In this case, the alarm device 2
Since the alarm (warning) by 1 has not been generated, the processing ends without any change in the state regarding the alarm operation.

When the timer alarm device 1 is returned and stored in the storage box 8 of the alarm setting device 7, the passenger does not need to remove the batch main body 2 from clothes or the like and return it, and the batch main body 2 remains as it is. Only the detachable tag portion 3 may be removed from the batch body 2 and returned to the storage box 8.

(2) When the passenger returns to the wrong bus and returns and stores the timer alarm device 1 (tag portion 3) in the storage box 8 of the alarm setting device 7 before the pre-bell time is reached. If you are traveling, each bus has its own timer alarm system,
Accordingly, it is assumed that a plurality of alarm setting devices 7 having different identification codes are used.

If the passenger returns to the wrong bus (a bus different from the bus on which he / she was riding before the start of free movement) and returns and stores the timer alarm device 1 in the storage box 8 of the alarm setting device 7, step B9 At storage device 1
Since the identification code of the alarm setting device 7 stored in 9 and the received identification code do not match, the control device 16 determines "NO", and proceeds to processing step B14 of "start of false vehicle alarm operation".

In process step B14, the controller 1
6 gives an output signal to the alarm device 21 and makes it intermittently ring to cause an erroneous boarding alarm operation (alarm operation). Therefore, at this point, the passenger can recognize that he has returned to the wrong bus.

If the timer alarm device 1 (tag portion 3) is taken out from the storage box 8 of the different alarm setting device 7, the control device 16 determines "NO" in steps B6, B7 and B8, and therefore the process proceeds to step B14. If the passenger returns to the correct bus and returns the timer alarm device 1, the processing is performed in the same manner as in (1).

(3) When the pre-bell time arrives before the passenger returns to the bus In this case, the control device 16 causes "Y" in step B7.
By determining "ES", the process proceeds to the processing step B13 of "preliminary alarm operation". In processing step B13, the control device 16 gives an output signal to the alarm device 21 and causes the alarm device 21 to intermittently ring to perform a preliminary alarm operation (preliminary alarm operation).

In this case, the preliminary alarm operation gives a slower impression than the alarm operation in step B14 by, for example, lengthening the sounding interval.
Then, after performing a preliminary alarm operation for an appropriate time (for example, 5 seconds), the process proceeds to step B6. If the passenger returns to the bus from this point in time to the set time, the process proceeds to step B6 → B9 → B10 → B11, and the process is terminated, as in the case of (1).

(4) When the passenger does not return to the bus after the set time has elapsed In this case, the count value of the timer device 20 becomes "0" in step B8, and the control device 16 becomes "YES". Then, the process shifts to step B12, the alarm device 21 is intermittently sounded, and the alarm operation is started. After that, the alarm continues by going around the loop of steps B6 → B7 → B8 → B12.

After that, when the passenger returns to the bus and returns and stores the timer alarm device 1 (tag portion 3) in the storage box 8 of the alarm setting device 7, the alarm setting device 7 outputs the identification code signal and the identification code signal in step A7 at that time. Since the alarm release signal is transmitted, the timer alarm device 1
The control device 16 of step B6 determines that the result of step B6, B9, and B10 is “YES”.
Move to 11. Then, the control device 16 controls the alarm device 2
When the output of the output signal to 1 is stopped and the alarm operation is stopped by stopping the ringing, the process ends.

In the case of (1), even if the passenger forgets to return the timer alarm device 1 to the storage box 8, an alarm similarly occurs when the set time elapses. It is possible to prevent forgetting to return it.

As described above, according to this embodiment, the control device 11 of the alarm setting device 7 sets the time until the set time for the plurality of timer alarm devices 1 housed in the housing box 8 to the set time. When the control device 16 of the timer alarm device 1 receives the set time signal, the control device 16 of the timer alarm device 1 sets the set time specified in the set time signal to the timer device 20 to start the time counting operation, and the control is performed. The device 11 transmits an alarm cancellation signal when the alarm cancellation time has elapsed, and the control device 16 causes the timer device 20 to stop the time counting operation (alarm cancellation) when the alarm cancellation signal is received, and the timer device 20 measures the time. When the set time reaches the set time, the alarm device 21
I've set up an alarm.

Therefore, it is possible to easily and collectively set the alarm generation time (set time) and cancel the alarm for a plurality of timer alarm devices 1, and the timer alarm device 1 is possessed. Since it is possible to notify passengers by an alarm that the set time has elapsed, it is possible to prevent passengers who have performed free action from being late for the set time or significantly delayed at the set time. , Can manage the itinerary more accurately.

Further, according to this embodiment, when a group tour is carried out by a plurality of buses, the passengers return to a different bus from the one on which they have finished their free activities before the alarm cancellation time and set an alarm. When the timer alarm device 1 is returned to the storage box 8 of the device 7, the control device 16 of the timer alarm device 1 alerts at that point because the transmitted identification code signal does not match the one stored in the storage device 19. If the passenger performs an action similar to the above while the device 21 issues an erroneous boarding alarm, and the alarm release time has elapsed and the alarm of the timer alarm device 1 is generated, again, due to the mismatch of the identification code signals. Since the alarm is not cleared, passengers can recognize that they have returned to a bus different from the one they were on in any case.

Further, according to the present embodiment, the control device 16 of the timer alarm device 1 sets a predetermined time according to the length of the set time when the set time signal is transmitted from the alarm setting device 7. Then, the alarm device 21 is caused to start the preliminary alarm operation a predetermined time before the set time. Therefore, by causing the preliminary alarm operation to be performed before the appropriate time according to the length of the set time, the passengers can get the set time. It is possible to reliably notify that the user is approaching.

In addition, according to the present embodiment, the timer alarm device 1 causes the liquid crystal panel 4 to display the set time transmitted as the display signal from the alarm setting device 7, so that the passenger can see the display on the liquid crystal panel 4. The set time can be visually recognized. Further, according to the present embodiment,
Since the predetermined area in which the alarm setting device 7 transmits the radio wave signal is the storage box 8, the output of the transmitting device 14 can be suppressed low.

Furthermore, according to this embodiment, the timer alarm device 1 is provided with the batch body 2 provided with the safety pin 5 and the clip 6, and the tag portion 3 detachably attached to the batch body 2. Since all the various electrical components are housed inside the tag section 3, the passenger
When the timer alarm device 1 is returned and stored in the storage box 8 of the alarm setting device 7, it is not necessary to remove the batch main body 2 from clothes or the like and return it. Just return it,
It is possible to improve convenience when performing free actions many times.

The input device 9a of the alarm setting device 7 is provided with a "check" switch, and the control device 11
When the "check" switch is turned on, the check signal is transmitted to the timer alarm device 1 in the storage box 8, and the control device 16 receives the check signal and changes the voltage of the battery 22. If the voltage is checked and the voltage is equal to or higher than a predetermined value, a low level signal is given to the LED 3c to turn on the LED 3c for normal display,
When the voltage is less than the predetermined value, the LED 3c is alternately given a high-level signal and a low-level signal to blink the LED 3c to display an abnormality, and the alarm device 21 is sounded to generate an alarm.

With this configuration, the timer alarm device 1
Since the battery check can be easily performed, it is possible to prevent the timer alarm device 1 from becoming inoperable during use due to the battery exhaustion. Further, when the voltage of the battery 22 is extremely low, it is possible to detect the dead battery by turning off the LED 3c.

In the battery checking operation described above, even if the alarm setting device 7 is not provided with a "check" switch, for example, when a signal is transmitted from the alarm setting device 7 to the timer alarm device 1 in step B1, the control device is operated. 16 may do it automatically.

By the way, in the present embodiment, the control device 16 of the timer alarm device 1 corrects the time of the timer device 20 by the following configuration. In FIG. 7, which shows a detailed configuration around the control device 16 and the timer device 20, which are not shown in FIG. 1, the clock input terminal of the timer device 20 is an oscillating circuit 23 using a ceramic oscillator.
The timer device 20 uses the clock signal output from the oscillation circuit 23 as a count clock.

Clock input terminal C of the correction counter 24
K is connected to the output terminal of the receiving device 17, and the receiving device 17 outputs to the correction counter 24 a waveform of the received radio wave signal only. The count output terminals (data buses) Q0, Q1, ..., Qn of the correction counter 24 are connected to the controller 16
Is connected to the input terminal (data bus) of the correction counter 24, and the correction counter 24 provides the controller 16 with a count output obtained by up-counting the clock signal input to the clock input terminal CK in binary. Further, the reset input terminal RES of the correction counter 24 is connected to the output terminal of the control device 16.

Although the ceramic vibrator is inexpensive, its accuracy is about 0.5%. If the allowable error of the timer device 20 is, for example, 1 minute per day, the required accuracy is about 0.07%. To satisfy this accuracy, an oscillator circuit using an expensive crystal oscillator is required. Therefore, the control device 16 calculates the correction coefficient as follows in order to correct the time of the timer device 20 that performs the counting operation based on the oscillation circuit 23 using the ceramic oscillator.

First, when the timer alarm device 1 is powered on and the control device 16 is started up, the control device 16 outputs a reset signal to the reset input terminal RES of the correction counter 24 to turn on the correction counter 24. Reset.
On the other hand, a high-precision crystal oscillator is used for the oscillation circuit for carrier wave output of the transmitter 14 of the alarm setting device 7,
The alarm setting device 7 outputs only the carrier wave for a certain period of time before transmitting various signals in step A4. Here, the frequency of the carrier wave is, for example, 1
It is set to 00 KHz.

Frequency 100 KH from alarm setting device 7
When the z carrier is transmitted and received by the receiving device 17 of the timer alarm device 1, the received signal is given to the correction counter 24 as a clock signal and also to the input terminal of the control device 16. Then, the correction counter 24 starts the count operation, and the control device 16 recognizes that the count operation of the correction counter 24 is started by the input of the reception signal as a trigger.

Then, the control device 16 causes the timer device 20 to
Then, the up count operation is started, and the gate time for referring to the count value of the correction counter 24 is measured by the count value of the timer device 20. here,
The gate time is, for example, 0.02 seconds, and the timer device 20
0.0 when the count value reaches 0.02 seconds divided by the cycle of the clock signal output from the oscillation circuit 23.
Judge that it has reached 2 seconds.

Then, the control device 16 reads the count value of the correction counter 24 when it is determined that 0.02 seconds have elapsed. When the gate time 0.02 seconds is accurate, the count value of the correction counter 24 is "2000", but the actual gate time is not 0.02 seconds due to the deviation of the accuracy of the oscillation circuit 23. . Therefore, a deviation occurs in the count value of the correction counter 24.

For example, if the count value of the correction counter 24 is "1990", the control device 16 calculates the correction coefficient C by the following equation. C = 1990/2000 = 0.995 Therefore, when the set time signal is transmitted from the alarm setting device 7 and the set time is set in the timer device 20, the set time is divided by the clock cycle of the oscillation circuit 23. Further, the value divided by the correction coefficient C is set as the count value. The resolution of the correction coefficient C in this case, that is, the accuracy is 1/2000.
(0.05%), and it is possible to sufficiently secure the accuracy required for the permissible error of 1 minute per day. Further, it is possible to perform the correction with higher accuracy by making the frequency of the carrier wave higher or making the gate time longer.

Even if a high-precision crystal oscillator is used only in the oscillator circuit of 14, the control device 16 can correct the correction coefficient C
By correcting the count value set in the timer device 20 by calculating, it is possible to improve the accuracy of the timing operation.
