Abstract

PURPOSE:To transmit a message to a person without fail by reproducing the voice message only when the existence of the person is judged by a detecting means for the existence of the person in the room even at the time for reproducing the voice message. CONSTITUTION:It is decided whether an inside sensor 32 and an outside sensor 31 are turned on or not. When the both sensors are not turned on, it is judged that no person passes and when they are turned on, it is judged which sensor is turned on first. When the outside sensor 31 is turned on first, a state for the person to enter the room is set at present and when the person advances further, the sensor 32 is turned on as well. Therefore, a step S05 is started and the loop of steps S05 and S04 is repeated. When the person advances further, the sensor 31 is turned off, the sensor 32 is turned off as well, and the passage is confirmed. When the person does not completely pass a passage sensor 3 but goes back in the middle, the sensor 31 is turned on again before the sensor 32 is turned off.

Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to an apparatus for reproducing a desired voice message at a scheduled time.

<Prior art> For example, a clock device that informs the user of necessary information by playing a voice message such as "Today is Mr. ___'s birthday" at a set date and time has been developed. It is being This generally includes means for recording a desired message or selecting a desired message from a plurality of messages, and means for reserving a date and time for reproducing the message.

<What the invention seeks to solve: With this type of device, when the reserved time arrives, a voice message is automatically played even if no one is present; If this message is played back, you will not be able to hear the message you need.

This invention was made with the aim of solving this problem and providing a device that reproduces a voice message after confirming the presence of one person - <Means for solving the problem> In order to achieve the above-mentioned object, the present invention includes a message setting/reproducing means for setting and reproducing a desired voice message, a scheduled time setting means for setting a time at which the voice message is to be reproduced, A person presence detection means detects the presence of a person in the target room, and after the time reserved in the reservation time setting means has arrived, it is determined by the person presence detection means that there is a person in the room. and a control section that operates the message setting/playback means to play a predetermined voice message.

FIG. 1 is a diagram showing the configuration of the present invention, where A is a reservation time setting means, B is a person presence detection means, C is a control section, D is a message setting/reproducing means, and Kj is a voice message.

Even if the reserved time set by the reserved time setting means arrives,
A voice message is played only when it is determined that there is a person in the room by the person presence detection means, and the voice message is reliably transmitted to the person in the room. 3. Embodiment Next, an embodiment shown in 1 will be explained. do. FIG. 2 is a block diagram of the apparatus, and FIGS. 3 and 4 are flowcharts of the control procedure.

In FIG. 2, 1 is a control unit, 2 is a time reservation switch,
3 is a passage sensor, 4 is a movement sensor, 5 is a recording/playback device such as a small tape recorder, and 6 is a recording switch.

The main part of the control unit 1 includes, for example, a ROM 71 that stores control programs, a CPL 72 that performs various calculations, a RAM 73 that is used for calculations, and a mask computer 7 that includes input/output circuits (not shown). There is.

The passage sensor 3 and the movement sensor 4 utilize ultrasonic waves, infrared rays, and the like, and these sensors constitute a person presence detection means. The passage sensor 3 consists of an outer sensor 31 and an inner sensor 32, which are arranged side by side at the entrance and exit of a room at an interval of about 20 m, and both sensors 31 and 32 are, for example, ultrasonic sensors. When the ultrasonic waves are interrupted, the passing of a person is detected, and the direction in which the person passes is detected based on the order in which the ultrasonic waves are interrupted. In addition, an ultrasonic sensor is used for the motion sensor 4, which emits ultrasonic waves toward the inside of the room, and detects the movement of the person by changing the human power state of the reflected wave and turns on. It is now able to detect when someone is in the room.

The second embodiment has the configuration as described above, and its operation will be explained next with reference to the flowcharts of FIGS. 3 and 4.

FIG. 3 shows the overall operating procedure. First, in step 500, the passage sensor 3 detects the entry and exit of people from the room.
−+J cut. This determination procedure will be described later with reference to FIG.

If no one is passing by, the process proceeds to step S10, where it is determined whether the recording switch 6 is set to the recording side, and if it is in the recording mode, the process proceeds to step S10, where the reserved time is set and the voice message is recorded. It will be done. Then, in the next step Si2, the count n is determined, and if it is not n-○, the process returns to step SOO, and if n=○, the count is set to 1 and the process returns to step SO○.

That is, since step Sll has been executed, it is determined that someone is in the room, and the count is set to at least 1. On the other hand, if the recording mode is not set in step S, the process advances to step 513, where it is determined whether the current time or the reserved time has arrived.If the reserved time has not yet arrived, the process advances to step S14, where the status of the motion sensor 4 is determined. It is judged that
If it is off, the process returns to step SO○, and if it is on, the process proceeds to step 512, where the count n is determined. Even if the current count is 0, if the motion sensor 4 is on, it means that there is a person in the room, so the count increases to 1 and the process returns to step S00.

If the current time matches the scheduled time in step 513, the process proceeds to step 515, where it is determined whether the voice message has already been played or not. If it has already been played, the process returns to step SOO, but since it has not been played for the first time, step 51
．． If the count is zero and it is determined that there is a person in the room, the recording/reproducing device 5 is activated in step S17 to reproduce the message, and the process returns to step S00. If the count is 0 and no one is present, the process advances to step 518 where the state of the motion sensor 4 is determined, and if the motion sensor 4 is off, this loop is repeated and no message is played. .

Then, when a person enters the room and the motion sensor 4 is turned on, the process advances to step 519 and after incrementing the count to 1,
The process advances to step 517 to reproduce the message, and then returns to step SOO.

Next, if it is determined in step SOO that a person has entered the room, the process advances to step S20, and it is determined whether the count is ○ or not.
In other words, it is determined whether there are already people in the room, and if the count is not 0, that is, if there are people in the room, the count is set to 2 to indicate that there are 2 people, and step 5
Proceed to step 10.

Further, when the count is ○, that is, when there is no one presently in the room, the count is set to 1 to indicate that there is one person in the room.

In addition, if it is determined in step SOO that a person has left the room, the process proceeds to step S30, where it is determined whether there are currently two people in the room, and if there are two people, the count is started. If the number is 1 or 0, the count is set to ○ and the process proceeds to step 510.

Next, with reference to FIG. 4, a description will be given of how the passage sensor 3 determines whether a person enters or exits.

In step S○1 and step 502, the inner sensor 32
Then, it is determined whether or not the outer sensor 31 is on.

If neither of them is turned on, it is determined that no person has passed, and the process proceeds to step S10. In addition, if it is turned on, it is determined which one turns on first, and if the outside sensor 31 is turned on first, it means that a person is about to enter, and the process advances from step 502 to step S○4. The loop of steps 502 and 504 is repeated. As the person advances further, the sensor 31 is also turned on, so the process proceeds to step 505, and the loop of steps S05 and SO2 is repeated, and as the person advances further, the sensor 31 is turned off and the process proceeds to step 506. and steps 505 and S
After the O2 loop is repeated, the sensor 32 is also turned off to confirm passage, and the process proceeds to step 520.

In addition, if the person does not completely pass the passing sensor 3 and turns back midway, the sensor 31 will be turned on again before the sensor 32 is turned off even if the person has proceeded to step 506, so step S○5 Return to loop 504. Also, in this loop, while the sensor 31 is on, the sensor 32
Since the sensor 31 is turned off, the process returns to the loop of steps 5.02 and 504, and soon the sensor 31 is also turned off. For this reason, no matter which step the process has progressed to, it goes backwards and proceeds to step S10 assuming that no person has passed.

Note that if it is not a person but an object that is smaller than the 20 unit interval between the sensors 31 and 32, such as a thin rod falling toward the room, the sensor 31 will turn on before the sensor 32 turns on. Since it is turned off, it is not determined that a person has entered the room, and the process proceeds from step S02 to step Sl○.

In addition, if a person tries to leave the room, the inner sensor 3
2 is turned on first, and then the process proceeds from step SO1 to step 507 in the same manner as described above. If a person passes through, the process proceeds to step 530 via step 508 and step 509. Also, if you turn back halfway, you will go backwards no matter which step you have progressed to, and you will finally proceed to step 510, assuming that no one has passed.

As described above, in this embodiment, the passage sensor 3 and the movement sensor 4 are used in combination as the person presence detection means. This is because only the motion sensor 4 for detecting human movement can handle 1
If a person is sleeping even if there is a person in the room, the motion sensor 4
will remain off, and you won't be able to play a wake-up message, for example. In addition, the passing sensor 3 alone may determine that there is no one in the room if there are multiple people in the room and only one person goes out, so even if a counter is attached to the passing sensor 3, This is to solve problems such as a lack of precision due to continued malfunctions.

In addition, in the example, the count number n is up to 2, but
This is to prevent the probability of malfunction of the count number increasing as the count number increases, and even if the count number reaches 0, it can be corrected by the motion sensor 4, so no particular problem occurs.

In addition, in the embodiment, a recording/playback device 5 such as a small tape recorder is used as a message setting/playback means to record a desired message, or, for example, a plurality of ready-made messages are prepared. It is also possible to adopt other means, such as a method of selecting and reproducing a desired message from among them, or a method of emitting a desired message using a speech synthesis circuit.

<Effects of the Invention> As is clear from the above-mentioned embodiments, in the second invention, even if the time to reproduce the voice message arrives, if the person presence detection means determines that there is no person in the room, This system does not play back messages, but only plays when it is determined that someone is present.

Therefore, like a device that automatically plays a message at the scheduled time even if no one is present, there is no need to listen to the necessary message because no one is present, and the message can be reliably played back by the person. It can be transmitted to
