Description

  The present invention relates to a sensor control device, and more particularly to a sensor control device with improved safety in a living environment.

In order to improve safety in the living environment, for consumer electronics and information devices, for example, measures for preventing accidents for children and the elderly are considered.
In a refrigerator having an automatic door, there is an example in which an automatic opening / closing function is stopped by continuously pressing a predetermined push button for several seconds to prevent the door from being opened or closed due to mischief. A door stopper for use in a refrigerator that does not have an automatic door is also commercially available.
In a washing machine, there is an example in which a lid is locked by continuously pressing a predetermined push button for several seconds to prevent an accident that a child falls into a washing layer filled with water. This type of lock is commonly called a child lock.

On the other hand, in the field of devices for identifying humans and animals, methods have been developed to identify individuals by detecting vibrations generated by their movement.
For example, when a frequency analysis is performed by detecting vibrations that occur when a person or animal walks, it is known that there is a clear difference in analysis results depending on the person or the person's footwear. It is also known that the vibration has a clear difference from, for example, an impact sound when the door is closed. For this reason, it has become possible to identify a person in action without being disturbed by noise by analyzing vibration.

Examples of applications of these technologies include the following systems and devices.
Patent Document 1 discloses a security system that detects a vibration applied to a walking surface in an indoor space and generates a notification signal when the acquired vibration information does not match the pre-stored natural vibration information. ing.
Patent Document 2 discloses an apparatus for accurately identifying an individual animal by detecting vibrations generated by the animal.

In order to stop the automatic opening and closing of the refrigerator door and lock the lid of the washing machine, conventionally, the setting with the push button as described above is necessary, so that the operation is troublesome, and the user forgets the setting. there were.
On the other hand, as a device for detecting vibration as described above, a detection device called a strain gauge or a strain sensor has been used for a long time. Many of them are provided with a metal foil, and the strain is detected in accordance with a change in electrical resistance due to, for example, pressure applied to the metal foil. However, the conventional strain sensor has a size of about several centimeters in the longitudinal direction, and it is necessary to provide an external amplifier for amplifying a weak signal indicating a change in electric resistance. For this reason, for example, it is not necessarily a suitable device for use in a consumer product.

  In contrast, recently, a new detection device called a semiconductor strain sensor is in the stage of practical use. A semiconductor strain sensor is a device that detects strain according to a change in piezoresistance of a semiconductor chip. The semiconductor chip has a size of, for example, 2 to 3 millimeters, and includes not only the distortion detection unit but also the above-described amplifier and an AD converter that converts the distortion detection value into data. The semiconductor chip is used by being mounted on a small substrate of about 10 mm square. For this reason, it can be mounted in a small and narrow place, and can be reduced in price due to the mass production effect, and is expected to be widely applied to consumer products.

However, the actual application method is in the stage of future development. For example, future development is awaited for applications that contribute to improving safety.
In view of the above situation, an object of the present invention is to provide a sensor control device with improved safety in a living environment.

  In order to solve the above problems, the present invention provides a sensor control device that controls a function in accordance with externally applied vibration, the strain sensor detecting the vibration and outputting a detection signal corresponding to the vibration, A control unit that receives the detection signal output from the strain sensor, analyzes the detection signal to detect the characteristic parameter of the vibration, and controls the overall operation of the sensor control device; and the operation controlled by the control unit and the sensor It has the main function part which performs the main function of a control apparatus.

  The present invention is also a sensor control device that controls a function in accordance with externally applied vibration, the strain sensor detecting the vibration and outputting a detection signal corresponding to the vibration, and the strain sensor outputs A control unit that receives the detection signal and analyzes the detection signal to detect a characteristic parameter of the vibration to control the overall operation of the sensor control device; and a main control unit of the sensor control device that is controlled by the control unit. A main function unit that executes a function and a function lock unit that is operation-controlled by the control unit and locks a part of the function of the sensor control device.

Embodiments of the present invention will be described below with reference to the drawings.
In this embodiment, vibration generated when a person moves is detected by a strain sensor, and a part of the sensor control device is adaptively controlled according to a vibration pattern obtained by analyzing the vibration. It is said. For example, if it is found from the vibration pattern obtained from the analysis that the child is walking and approaching, some functions of the sensor control device may be restricted or stopped to make the child dangerous. It is characterized by protecting from.

  FIG. 1 is a first block diagram of a sensor control device 1 according to an embodiment. Here, the sensor control device 1 is a device controlled by a strain sensor 12 typified by the semiconductor strain sensor described above, for example. Of course, the strain sensor 12 is not limited to a semiconductor strain sensor. The sensor control device 1 may be consumer electronics such as a washing machine, a refrigerator, a kitchen stove, an air conditioner, and a kettle.

  The control unit 11 includes a CPU (Central Processing Unit) or a DSP (Digital Signal Processor) for performing overall operation control of the sensor control device 1. The control unit 11 supplies a control signal to the main function unit 15 to control rotation of, for example, a washing drum if the sensor control device 1 is a washing machine, and to control operation of a cooling cycle if the sensor control device 1 is a refrigerator. If it is an air conditioner or an air conditioner, the heating unit or the cooling unit is controlled.

  Further, the control unit 11 is supplied with vibration data detected by the strain sensor 12 at predetermined time intervals, for example, by sending a clock to the strain sensor 12. There may be a control in which the control unit 11 detects the amplitude of the vibration data and stops the main function unit 15 when the amplitude is larger than a predetermined value. In the following embodiments, the control unit 11 analyzes the vibration data, identifies a person who has generated vibrations with reference to, for example, a vibration pattern registered in the memory 14, and determines the function lock unit 13 according to the result. A case where a predetermined function in the sensor control device 1 is locked by supplying a lock control signal will be described.

The predetermined function locked by the function lock unit 13 is, for example, an automatic door opening / closing function in a refrigerator. In the washing machine, it is a function of opening and closing the door of the laundry layer, commonly called child lock. In the air conditioner, it is a function of an operation panel for adjusting temperature setting and air volume. In a kitchen stove or a water heater pot, in addition to invalidating the function of the operation unit, all functions may be stopped by turning off the power.
In FIG. 1, components for controlling the operation of the main function unit 15 are provided separately from the control unit 11, and for example, another semiconductor device may be provided.

  FIG. 2 is a first sketch of the sensor control device 1 in one embodiment, and shows a case where the sensor control device 1 is a drum type washing machine. Reference numeral 2 denotes a moving person. Here, the person moves in the direction of the arrow in the figure, and for example, it is assumed that the vibration described below the arrow is generated in the time axis direction.

  The sensor control device 1 has, for example, a strain sensor 12 on a leg in contact with a floor surface to be installed. Thereby, the vibration transmitted on the floor surface is detected with high sensitivity. That is, the strain sensor 12 is preferably attached in the vicinity of the installation part of the sensor control device 1. The strain sensor 12 detects vibration generated by the movement of the person 2 and supplies detection data to the control unit 11. The control unit 11 analyzes the supplied data as will be described in detail later, and identifies the person 2. For example, in the case where the approaching person 2 is a child, there is a risk of falling into the laundry layer when the door of the drum type washing machine is opened. At this time, the control unit 11 instructs the function lock unit 13 to lock the door 13A so as not to open. As shown in the figure, when the function lock unit 13 also serves as a push button for opening and closing the door, a control signal normally generated according to the push button is not generated. As will be described later, the control unit 11 can determine whether the person 2 is approaching or moving away from the sensor control device 1. In the latter case, there is no particular danger, and useless operation can be avoided if the door is not locked.

  FIG. 3 is a second sketch of the sensor control device 1 in one embodiment, and shows a case where the sensor control device 1 is a large refrigerator. The illustrated large refrigerator has six doors 13B to 13G as an example. Depending on the model, some of these doors are, for example, push button type automatic doors.

  If the sensor control apparatus 1 is a refrigerator with an automatic door, the function lock part 13 (not shown in FIG. 3) for locking an automatic door at least will be provided in the inside of a refrigerator, for example. When the approaching person 2 is a child, the function lock unit 13 stops the automatic door opening / closing function. Alternatively, when the function lock unit 13 also serves as a push button (not shown in FIG. 3) for opening and closing the door, a control signal that is normally generated according to the push button is not generated. As a result, it is possible to solve the problem that the door is opened due to a mischievous mischief and the temperature in the refrigerator rises, or the hand is caught in the door. For doors that are not automatic or refrigerator doors that do not have an automatic door, the door may be locked when a child approaches, so that it cannot be opened manually.

  If the sensor control device 1 is an air conditioner, it is possible to prevent mischief operations by disabling the function of the operation panel. If the sensor control device 1 is a kitchen stove or a hot water heater, the danger of the operation can be avoided by disabling the function of the operation unit or turning off the power to stop all functions. Even when the person 2 is an elderly person with a disability, not limited to a child, the person can be identified in the same manner to avoid danger or prevent the apparatus from performing useless operations. Moreover, in any of the embodiments so far, unlike the conventional child lock function, for example, there is an effect that it is possible to prevent the occurrence of an accident due to forgetting the lock.

  FIG. 4 is a third sketch of the sensor control device 1 in one embodiment, and is a plan view seen from the ceiling side of the room in which the sensor control device 1 is installed. Here, the type of the sensor control device 1 is not particularly limited. Unlike FIG. 2 and FIG. 3, FIG. 4 includes four strain sensors 12a to 12d. These are installed in four different places in the room where the sensor control device 1 is installed, and are preferably provided in contact with the floor so that vibration transmitted through the floor can be detected with high sensitivity. Of course, the installation location is not limited to four locations, and may be a plurality of locations. The vibration data detected by the strain sensors 12a to 12d is supplied to the control unit 111 of the sensor control device 1 via a wired or wireless communication path (indicated by a broken arrow in the figure).

By analyzing a plurality of vibration data, the control unit 111 does not only determine whether or not the person 2 is approaching, but in any direction in the plane as shown by the solid arrow in the figure. Whether it is moving or not can be determined in more detail than in the case of FIGS. For example, when the person 2 moves straight toward the sensor control device 1, some functions are stopped. When the person 2 moves away from the sensor control device or approaches the person 2 but does not go to a dangerous place such as a door of the washing machine, the function is not stopped. In this way, the problem of frequently repeating unnecessary function stop operations can be solved.
In the present embodiment, the vibration pattern generated by the moving body is detected by using the method described above, the moving body is specified, the moving direction is determined, and some functions of the sensor control device 1 are performed based on the result. For example, safety is improved.

Next, a method for specifying the person 2 will be described.
FIG. 5 is a flowchart of a vibration characteristic parameter detection method according to an embodiment. The waveform diagram in FIG. 5 shows an example of vibration detected by the strain sensor 12. The vibration that occurs when an animal such as a person moves is similar to each step on the time axis as shown in the figure, but the vibration waveform for each step, its envelope waveform, and the vibration for multiple steps A lot of information can be obtained by frequency analysis of the waveform of the envelope. For example, it has become possible to specify whether a moving body is a human being or another animal, whether it is a child, the presence or absence and type of footwear, the type of floor, and who it is.

These determinations are made with reference to vibration patterns and frequency distributions registered in advance in the memory 14. When the ratio of the high-frequency component of vibration is greater than a predetermined amount, or when the walking pitch is short, the moving person can be determined as a child. If vibration patterns are registered for a plurality of people, it is possible to specify with high accuracy who is moving. The vibration pattern and frequency distribution information registered in advance may be registered not only in the memory 14 of each sensor control device 1 but also in the memory of a host device that supervises the sensor control device 1. The latter embodiment is effective in the field of network home appliances. In that case, the sensor control device 1 includes a communication processing unit (not shown).
In addition, when specifying a person, in order to specify exactly who it is, it is necessary to learn a vibration pattern generated by walking the person in advance. However, as described with reference to FIGS. 2 and 3, in order to know whether or not the child is simply a child, for example, the ratio of high frequency components and the pitch of walking may be compared with a predetermined value. In the latter case, it is not necessary for the user to perform time-consuming learning, which is suitable for use in a consumer device.

FIG. 6 is a diagram illustrating an example of the frequency characteristic of vibration in one embodiment, and shows a case of a moving body different between a solid line and a broken line. This frequency characteristic may be obtained from the vibration waveform of one step, but when it is obtained by detecting the envelope of the vibration waveform, a difference in physical characteristics such as body size clearly appears. It is said that it is easy to grasp the characteristics.
FIG. 7 is a diagram illustrating an example of characteristic parameters on the frequency axis in one embodiment. By obtaining the intensity at a predetermined frequency as a discrete sample value from the frequency spectrum shown in FIG. 6 and registering a predetermined number of sample values in the memory 14, it can be used for determination of the moving object.

FIG. 8 is a diagram illustrating an example of an envelope waveform of vibration in one embodiment. When the intensity of the envelope of the vibration waveform described above increases for a while, it can be known that the moving body is approaching. The period of the envelope, that is, the pitch of walking, is also a characteristic parameter for specifying the moving body, and varies depending on the person, and is important for discriminating between children and adults.
A more advanced control method using the method described above will be described.

When the control unit 11 analyzes the vibration detected by the strain sensor 12, for example, the presence of a plurality of moving bodies can be known by using frequency analysis. If both children and adults are moving, the risk is likely to be less than for a single child. Therefore, in this case, the control unit 11 does not need to instruct the function lock unit 13 to lock the door, for example.
On the other hand, when an adult leaves the vicinity of the device and a child returns alone, there is a high risk of accidents due to mischief. Therefore, in this case, when the vibration generated by the adult is not detected and the vibration of only the child is detected after a predetermined time, the control unit 11 may instruct the function lock unit 13 to lock the door, for example.

  In electrical appliances such as refrigerators and washing machines, the device itself may generate vibrations larger than those of people walking. Therefore, if the standard vibration pattern of the apparatus itself is registered in the memory 14 in advance, the influence of the vibration of the apparatus itself is removed from the vibration detected by the strain sensor 12, and the control unit 11 analyzes the vibration. Highly accurate determination can be made. If the vibration pattern of the device itself is actually measured and registered in the actual installation state, it can be determined with higher accuracy.

  If a vibration pattern generated by each person using the sensor control device 1 is registered as a vibration pattern to be registered in the memory 14, the set state can be made suitable for each person. For example, when the sensor control device 1 is an air conditioner, a vibration pattern learning function is provided, and the vibration pattern of vibration generated by the set person is stored in the memory 14 together with the room temperature set by a certain person. Thereafter, when the vibration pattern obtained by analyzing the vibration detected by the strain sensor 12 is similar to any one of the vibration patterns stored in the memory 14, the control unit 11 performs the main function unit 15. To adjust the temperature setting of the air conditioner to the room temperature previously set by the person. In this way, the trouble of setting the temperature every time it is used can be omitted.

As can be inferred from the matters described above, the occurrence of an earthquake can be detected by analyzing the vibration pattern. When the vibration similar to the earthquake vibration pattern registered in the memory 14 is detected, the control unit 11 instructs the function lock unit 13 to lock, for example, the door of the refrigerator or the washing machine, or the washing machine, Stops some of the functions of the air conditioner and kettle pot. This has the effect of reducing the risk of an earthquake occurring. Here, important specific patterns such as earthquake vibration patterns may be included in a part of the control method (processing program or the like) of the control unit 11 instead of being registered in the memory 14.
As described above, the vibration pattern to be generated changes depending on the material of the floor, but the detection method of the vibration pattern may be switched according to this. For example, as a vibration pattern to be registered in the memory 14, a plurality of vibration patterns corresponding to the floor material may be registered for the same person, and any one may be selected and detected. Alternatively, even if there is only one vibration pattern to be registered, a function corresponding to the floor material may be calculated and detected.

  The sensor control apparatus 1 locked by detecting the specific vibration pattern described in the above embodiment releases the lock after detecting that the specific vibration pattern is not detected for a predetermined time. Alternatively, when the sensor control device 1 is locked by detecting a vibration pattern by a child, the lock may be released by detecting the vibration pattern by an adult.

Next, a case where the sensor control device 1 is a television device with a communication function will be described as an embodiment. As is well known, many television devices that are particularly compatible with digital broadcasting have a function of performing data communication with other communication devices via a network. An example of improving safety using this communication function will be described.
FIG. 9 is a flowchart of a detection result notification method in one embodiment. First, it is assumed that the person 2 accidentally falls. The vibration due to the fall propagates through the floor and is transmitted to the sensor control device 1 which is a television device. The strain sensor 12 included in the sensor control device 1 functions to detect the vibration and start a predetermined operation to ensure the safety of the person 2. It should be noted that since the vibration pattern caused by a person's falling is completely different from a normal vibration pattern such as walking, it is possible to detect the occurrence of abnormality.

FIG. 10 is a fourth sketch of the sensor control device 1 in one embodiment. The sensor control device 1 is a television device having a display panel 156, and the strain sensor 12 is attached to, for example, a leg 16 of the device so as to detect the vibration of the installed floor with high sensitivity.
FIG. 11 is a second block diagram of the sensor control device 1 in one embodiment. In the signal processing unit 15 which is a main function unit, a radio signal of a television broadcast received by an antenna 151 (which may of course be externally attached) is supplied to the tuner 152, and a channel designated by the user from a plurality of received channels Are received and then supplied to the video / audio processor 155. In the video / audio processing unit 155, the expanded video signal is released from the data compression performed on the broadcasting station side and supplied to the display panel 156 to display video, and the audio signal is supplied to the speaker 157 to output audio. Occur.

The system control unit 11A corresponds to a part of the control unit 11 in FIG. 1 and controls the overall operation of the signal processing unit 15 described above. For example, when an interactive program specific to digital broadcasting is received, the system control unit 11A instructs the communication processing unit 158 to connect the output terminal 159 and the network for information including, for example, a quiz program answer. To the other party such as a broadcasting station. Further, the sensor control apparatus 1 may include a built-in camera 153 and a built-in microphone 154, and may transmit information obtained by capturing and collecting sound to other destinations via the output terminal 159 and a network.
Further, the sensor control device 1 includes a vibration analysis unit 11B, a strain sensor 12, and a memory 14 corresponding to a part of the control unit 11 in FIG. The vibration analysis unit 11B may be integrated with the system control unit 11A. In this case, both correspond to the control unit 11 of FIG. The memory 14 may share an existing memory (not shown) in the signal processing unit 15. The strain sensor 12 is preferably attached to a place where vibration is easily detected as shown in FIG.

As a result of analyzing the vibration detected by the strain sensor 12 by the vibration analysis unit 11B, when it is determined that the person 2 has fallen as shown in FIG. 9, the vibration analysis unit 11B instructs the system control unit 11A, Emergency information notifying that the person has fallen is transmitted via the output terminal 159 and the network. Relatives and friendly people are appropriate as the transmission destination, and it is desirable that the apparatus has a function of registering an emergency contact address. If necessary, video captured by the built-in camera 153 and sound collected by the built-in microphone 154 may be transmitted to convey the situation in the room. In addition, the communication via the network is bidirectional, and a function of reproducing the video and audio received from the transmission destination by the display panel 156 and the speaker 157 may be added to enable a call to the person 2. . In this case, the situation can be grasped more accurately by looking at the reaction of the person 2.
By doing so, for example, safety in the life of the elderly can be further improved.

Note that the sensor control device 1 shown in FIG. 11 alerts other people to the occurrence of an earthquake via the output terminal 159 and the network when the strain sensor 12 detects vibration due to the earthquake, and calls attention. Application is also possible.
More recently, security cameras have become widespread in ordinary households. An increasing number of cameras have a function of issuing an alarm signal and reporting to a destination via a unique network. Although it is effective to provide a strain sensor in the security camera in the same manner as the apparatus shown in FIG. 11, emergency information generated by the apparatus in FIG. You may make it perform the cooperation operation | movement for improving.

As described above, the embodiment shown in FIGS. 9 to 11 shows an application method of the strain sensor 12 using the existing function of the sensor control device 1.
