In this case, the rear wheel 24 can be locked (rotation prohibited state) by operating the braking device 26 in a state where the rear wheel 24 is not rotating. The braking device 26 may brake or lock the rotation of the front wheel 23 instead of the rear wheel 24 or in combination with the rear wheel 24.

  The lock release switch 27 is a switch for releasing the lock by the braking device 26. The lock release switch 27 is provided, for example, in the vicinity of the handle 50, and is used for releasing (turning off) the lock when the operator causes the child to push the baby stroller 10 (help the child).

  The alarm unit 62 issues an alarm to the operator under the instruction of the control unit 61. As the alarm unit 62, a speaker that emits a warning sound or a vibrator that notifies the warning (assumed to be provided on the handle 50) can be employed. In this embodiment, it is assumed that a speaker is employed as the alarm unit 62.

  The communication unit 63 transmits an instruction from the control unit 61 to the terminal 70. The control unit 61 gives an instruction to issue an alarm from the terminal 70 when the operator does not touch the handle 50 of the stroller 10.

(Terminal 70)
As shown in FIG. 3, the terminal 70 includes a terminal communication unit 71 and a terminal alarm unit 72.

  The terminal communication unit 71 receives an instruction from the control unit 61 transmitted from the communication unit 63 of the electronic device 60 and transmits the instruction to the terminal alarm unit 72. The terminal alarm unit 72 issues an alarm to the operator based on the instruction of the control unit 61 transmitted from the terminal communication unit 71. In addition, as the terminal alarm part 72, the speaker which emits a warning sound and the vibrator which notifies a warning are employable. In this embodiment, it is assumed that a speaker is employed as the terminal alarm unit 72.

  Next, processing by the control unit 61 of the electronic device 60 will be described in detail with reference to the flowcharts of FIGS. 5, 9 to 12, and 16. The control unit 61 performs three processes of a safety maintenance process (FIG. 5), an accidental ingestion prevention process (FIG. 9), and a fall prevention process (FIG. 16) in parallel.

(Safety maintenance process)
FIG. 5 shows a flowchart of the safety maintenance process performed by the control unit 61. This safety maintenance process is a process for maintaining safety in operating the stroller 10, and specifically, a process for preventing a child from operating the stroller 10 and a speed reduction during downhill driving. Includes processing to prevent overloading. As a premise of the processing in FIG. 5, it is assumed that the operator does not hold the handle 50 and the rear wheel 24 of the stroller 10 is locked.

  In the process of FIG. 5, first, in step S <b> 110, the control unit 61 waits until the handle 50 is gripped. When the handle 50 is gripped by the operator, the contact pressure is detected by at least one of the first to third pressure sensors 52a to 52c provided on the handle 50. Therefore, the control unit 61 detects the contact pressure detection result. Is acquired, the process proceeds to step S112.

  If transfering it to step S112, the control part 61 will judge whether the handle | steering-wheel 50 is grasped with both hands. The controller 61 determines whether or not the handle 50 is grasped with both hands based on whether contact pressure is detected by the second pressure sensor 52b and the third pressure sensor 52c provided at both ends of the handle 50. be able to. Here, in order to safely operate the stroller 10, it is desirable that the right hand holds the position of the second pressure sensor 52b and the left hand holds the position of the third pressure sensor 52c. Therefore, in step S112, when the contact pressure is detected by the second pressure sensor 52b and the third pressure sensor 52c, it is determined that the handle 50 is held with both hands. If the determination in step S112 is affirmed, the process proceeds to step S116. If the determination is negative, the process proceeds to step S114.

  In step S114, the control unit 61 determines whether or not the center of the handle 50 is gripped. In this case, the control unit 61 makes a determination based on whether or not the contact pressure is detected by the first pressure sensor 52a. If the determination in step S114 is affirmed, the process proceeds to step S116. If the determination is negative, the process proceeds to step S134. When the determination in step S114 is affirmed, the process proceeds to step S116 (the process proceeds to the same process as when the handle 50 is held with both hands). Even if you hold it or put an umbrella on a rainy day (when it is difficult to hold the handle 50 with both hands), if you hold the center of the handle 50 with one hand, you can press the stroller 10 stably. It is because it can do.

  When the process proceeds to step S116, the control unit 61 acquires the position at which the operator grips the handle 50 and the gripping pressure from the first to third pressure sensors 52a to 52c. Next, in step S117, the control unit 61 calculates the area where the operator is holding the handle (the area in contact with the first to third pressure sensors 52a to 52c). Next, in step S120, the control unit 61 determines whether the operator is an adult. Here, the adult is not specifically defined by age, such as “how old or older”, but means a physically and mentally mature person who can safely operate the stroller 10.

  FIG. 6 shows a state where an adult is operating the stroller 10, and FIG. 7 shows a state where a child is about to operate the stroller 10. FIG. 8A schematically shows the state of the hand and the handle when the adult holds the handle 50, and FIG. 8B shows the hand and the hand when the child holds the handle 50. The state of the handle is schematically shown. As shown in these drawings, when an adult grips the handle 50 of the stroller 10, the handle 50 is gripped from the upper side of the handle 50, and when a child grips the handle 50, the handle is pulled from the side or the lower side of the handle 50. Hold 50. In addition, since the size of the hand is different between an adult and a child, the area of the region where the hand and the handle 50 come into contact with each other when the handle 50 is gripped (area A in FIGS. 8A and 8B), and The areas of the non-contact areas (area B in FIGS. 8A and 8B) are different. Therefore, the difference between an adult and a child can be determined from the contact portion between the hand and the handle 50 and the size of the contact area. Therefore, in the present embodiment, in step S117, the control unit 61 calculates the contact area of the handle 50 and the hand, and in step S118, based on the contact area, whether or not the person holding the handle 50 is an adult. It is going to be judged.

  If the determination in step S118 is affirmative, that is, if the person holding the handle 50 is an adult, the control unit 61 proceeds to step S120. On the other hand, if the determination in step S118 is negative, the process proceeds to step S128.

  When the process proceeds to step S120, the control unit 61 unlocks the rear wheel 24 by the braking device 26. This is because since the person holding the handle 50 is an adult, there is no problem in safety even if the lock is released.

  Next, in step S122, the control unit 61 calculates the inclination of the stroller 10. In this case, based on the detection result of the inclination sensor 33, the control unit 61 can grasp whether the vehicle is downhill, uphill, or flat.

  Next, in step S124, the control unit 61 determines whether the stroller 10 is located on a downhill. If the determination here is affirmed, the process proceeds to step S126, and the speed limit operation is executed. In this case, the control unit 61 calculates the vehicle speed of the stroller 10 from the detection result of the rotation sensor 25 and issues an instruction to the braking device 26 as necessary so that the speed does not exceed a predetermined speed limit. Brake. Thereafter, the process proceeds to step S140.

  If the determination in step S124 is negative, the process proceeds to step S140 without passing through step S126.

  When the process proceeds to step S140, the control unit 61 determines whether the state of the hand holding the handle 50 has changed (for example, whether the handle is no longer held). When judgment here is denied, it returns to step S122. On the other hand, if the determination in step S140 is affirmative, the entire process of FIG.

  If the determination in step S118 is negative, that is, if the person holding the handle 50 is a child, the process proceeds to step S128, and the control unit 61 determines whether or not unlocking is necessary. To do. For example, when the child pushes the stroller 10 with the help of an adult, the adult turns off the lock release switch 27 (the lock is released), so that the control unit 61 has the lock release switch 27 turned off. Therefore, it is determined that unlocking is necessary. When the determination in step S128 is affirmed, the process proceeds to step S130, and the control unit 61 releases the lock of the rear wheel 24 by the braking device 26. And in step S132, the control part 61 performs speed limit driving | operation. Here, since the child is going to operate the stroller 10, the braking device 26 is controlled so that the speed does not exceed a predetermined speed in consideration of safety. The predetermined speed here may be the same speed as the predetermined speed in step S126, or may be a different speed.

  Next, in step S142, the control unit 61 waits until the state of the hand gripping the handle 50 changes (for example, until the handle is not gripped). And the control part 61 complete | finishes all the processes of FIG. 5 in the stage in which the state of the hand holding the handle | steering-wheel 50 changed.

  When the determination at step S114 is negative (when the handle 50 is not properly gripped) and when the determination at step S128 is negative (when the child is holding and the lock is not released). Proceeds to step S134. And in step S134, the control part 61 maintains the lock | rock of the rear-wheel 24 by the braking device 26, and is the stage (step S142: the stage where it became affirmation) after that the state of the hand holding the handle | steering-wheel 50 changed. All the processes in FIG. 5 are terminated.

  In the process of FIG. 5, the control unit 61 may cause the alarm unit 62 or the terminal alarm unit 72 of the terminal 70 to issue an alarm when the determination in step S <b> 118 is denied. Thereby, it is possible to notify the guardian that the child is about to operate the stroller 10.

(Anti-drinking prevention process)
Next, the accidental ingestion prevention process will be described along the flowcharts of FIGS. 9 to 12 with reference to other drawings as appropriate. This process is a process for preventing an infant in the stroller 10 from accidentally swallowing an object such as a toy. The process in FIG. 9 is started from a stage where, for example, it is detected by the load sensor 31 that an infant is placed in the stroller 10. However, the present invention is not limited to this. For example, the process of FIG. 9 may be started from the stage where the handle 50 is gripped by the operator.

  In the process of FIG. 9, first, in step S210, the control unit 61 executes a hand area change detection routine. In this routine, processing according to the flowchart of FIG. 10 is executed. In the process of FIG. 10, in step S <b> 211, the control unit 61 acquires image information captured by the imaging device 41. Next, in step S212, the control unit 61 analyzes the image information acquired in step S211 and calculates the area of the hand of the infant riding on the stroller 10.

  In this case, for example, the control unit 61 extracts a hand region from image information based on a sample image of an infant hand prepared in advance. Then, the control unit 61 calculates the area of the hand region. Here, the area of the hand changes according to the distance between the imaging device 41 and the hand (the area of the hand increases when the hand is closer to the imaging device 41, and the area of the hand decreases when the hand is far). Therefore, when calculating the area of the hand, for example, the area of the hand may be quantified on the basis of the size of the infant's nail (for example, 1). In addition, when the image of the nail is not included in the captured image, the area of the hand may be calculated based on another part (for example, thumb).

  Next, in step S <b> 213, the control unit 61 determines whether information regarding the hand area is already accumulated in the built-in memory of the control unit 61. When judgment here is affirmed, it transfers to step S214. On the other hand, if the determination in step S213 is negative, the process returns to step S211.

  If transfering it to step S214, the control part 61 will judge whether the area of the hand of the infant has changed. Here, FIG. 13 (a) shows a state where the infant holds the hand without holding anything, and FIG. 13 (b) shows a state where the infant holds the object. As shown in FIGS. 13A and 13B, when the infant has an object, the infant's hand cannot be completely closed (cannot be gripped), and the area occupied by the hand on the image changes. Therefore, when the hand area of the infant changes, it can be determined that the infant is likely to have an object. If the determination in step S214 is negative, the entire process in FIG. 10 is terminated and the process proceeds to step S220 in FIG. 9. If the determination in step S214 is affirmative, the process proceeds to step S215.

  When the process proceeds to step S215, the control unit 61 determines whether or not the rear wheel 24 is unlocked. The case where the lock is released means the case where the operator holds the handle 50 of the stroller 10, and the case where the lock is not released means that the operator holds the handle 50 of the stroller 10. For example, it means a case where the child is away from the stroller 10. If the determination in step S215 is affirmed, the process proceeds to step S216, and the control unit 61 issues an alarm from the alarm unit 62 provided in the stroller 10 to the operator holding the handle 50 of the stroller 10. put out.

  On the other hand, if the determination in step S215 is negative, the process proceeds to step S217, and the control unit 61 issues an alarm from the terminal 70 (terminal alarm unit 72) to the operator who does not hold the handle of the stroller 10. .

  Note that the alarm in steps S216 and S217 may simply output an alarm sound, but for example, the current state of the infant such as “the child may have something in his hand”. May be explained. Further, if the name of the infant is registered in the electronic device 60 in advance, an alarm may be issued such as “There is a possibility that XX-chan has an object in his hand.”

  After the process in step S216 or step S217, the control unit 61 ends all the processes in FIG. 10 and proceeds to step S220 in FIG.

  Returning to FIG. 9, in step S220, the control unit 61 determines whether an alarm is issued in the subroutine of step S210 (steps S216 and S217 have been passed). If the determination here is affirmed, the process proceeds to step S230. If the determination is negative, step S210 is repeated.

  In step S230, the control unit 61 executes a mouth area decrease detection routine. In this routine, processing according to the flowchart of FIG. 11 is executed.

  In the process of FIG. 11, the control unit 61 acquires image information captured by the imaging device 41 in step S231. Next, in step S232, the control unit 61 analyzes the image information acquired in step S231, and calculates the area of the mouth of the infant riding on the stroller 10.

  In this case, for example, the control unit 61 extracts a mouth region from image information based on a sample image of a baby's mouth prepared in advance. Then, the control unit 61 calculates the area of the mouth region. Here, the area of the mouth changes according to the distance between the imaging device 41 and the mouth (the area of the mouth increases if the imaging device 41 is close to the mouth, and the area of the mouth decreases if the distance is far). Therefore, when calculating the area of the mouth, for example, the area of the mouth may be quantified on the basis of the size of the infant's face (for example, 100). Note that the area of the mouth may be calculated based on the size of the nose and eyes instead of the size of the face.

  Next, in step S <b> 233, the control unit 61 determines whether information related to the mouth area of the infant is already stored in the built-in memory of the control unit 61. When judgment here is affirmed, it transfers to step S234. On the other hand, if the determination in step S233 is negative, the process returns to step S231.

  If transfering it to step S234, the control part 61 will judge whether the area of the mouth of the infant is decreasing. Here, FIG. 14A shows a state when the infant's mouth is not hidden by the hand, and FIG. 14B shows a state when a part of the infant's mouth is hidden by the hand. It is shown. As shown in FIGS. 14 (a) and 14 (b), when an infant has a hand holding an object close to the mouth, the infant's mouth is hidden by the hand, so the area occupied by the infant's mouth on the image decreases. To do. Therefore, when the area of the infant's mouth is decreasing, it can be determined that there is a high possibility that the infant has his hand close to the mouth. If the determination in step S234 is negative, the entire process in FIG. 11 is terminated and the process proceeds to step S240 in FIG. 9. If the determination in step S234 is affirmative, the process proceeds to step S235.

  When the process proceeds to step S235, the control unit 61 determines whether or not the rear wheel 24 is unlocked. If the determination in step S235 is affirmative, the process proceeds to step S236, and the control unit 61 is provided in the stroller 10 for the operator holding the handle 50 of the stroller 10 as in step S216 described above. An alarm is issued from the alarm unit 62. On the other hand, if the determination in step S235 is negative, the process proceeds to step S237, and the control unit 61 notifies the terminal 70 (terminal alarm) to the operator who does not hold the handle of the stroller 10 as in step S217 described above. Alarm is issued from part 72).

  Note that the alarm in steps S236 and S237 may simply output an alarm sound. For example, the current state of the infant such as “the child may be bringing an object close to his / her mouth”. May be explained. Further, if the infant's name is registered in the electronic device 60 in advance, an alarm may be issued such as “There is a possibility that XX (the name of the infant) is approaching the mouth.” .

  After the processing in step S236 or step S237, the control unit 61 ends all the processing in FIG. 11 and proceeds to step S240 in FIG.

  Returning to FIG. 9, in step S240, the control unit 61 determines whether an alarm is issued in the subroutine of step S230 (steps S236 and S237). When judgment here is affirmed, it transfers to step S250, and when negative, step S230 is repeated.

  In step S250, the control unit 61 executes a mouth shape change detection routine. In this routine, processing according to the flowchart of FIG. 12 is executed.

  In the process of FIG. 12, the processes and determinations from steps S251 to S253 are executed in the same manner as steps S231 to S233 of FIG. Then, when the process proceeds to step S254, the control unit 61 determines whether or not the shape of the infant's mouth has changed based on the change in the mouth area. Here, FIG. 15A shows a state when the infant closes his / her mouth, and FIG. 15B shows a state when the infant opens his / her mouth. As shown in FIGS. 15 (a) and 15 (b), when the infant opens his / her mouth from the closed state, the shape of the infant's mouth changes. As shown in FIG. 15 (b), when an infant has a hand holding an object close to the mouth and the shape of the infant's mouth changes, it may be determined that there is a high possibility that the infant is about to put the object into the mouth. it can. If the determination in step S254 is negative, the entire process in FIG. 11 is terminated, and the process proceeds to step S260 in FIG. On the other hand, if the determination in step S254 is affirmed, the process proceeds to step S255.

  When the process proceeds to step S255, the control unit 61 determines whether or not the rear wheel 24 is unlocked. When the determination in step S255 is affirmed, the process proceeds to step S256, and the control unit 61 provides the stroller 10 to the operator holding the handle 50 of the stroller 10 in the same manner as in steps S216 and S236 described above. An alarm is issued from the alarm unit 62 provided in the. On the other hand, if the determination in step S255 is negative, the process proceeds to step S257, and the control unit 61, like the above-described steps S217 and S237, provides the terminal 70 ( An alarm is issued from the terminal alarm unit 72).

  Note that the alarms in steps S256 and S257 may simply output an alarm sound. For example, the current child's infant may be trying to put something in his mouth. The state may be explained. Also, if an infant's name is registered in the electronic device 60 in advance, an alarm may be issued such as “XX-chan (infant's name) may be trying to put something in his mouth.” Good.

  After the process of step S256 or step S257, the control unit 61 ends all the processes in FIG. 12, and proceeds to step S260 in FIG.

  Returning to FIG. 9, in step S260, the control unit 61 determines whether an alarm is issued in the subroutine of step S250 (after steps S256 and S257). If the determination here is affirmed, the process proceeds to step S270. If the determination is negative, step S250 is repeated.

  In step S270, the control unit 61 determines whether or not there is any response to the alarm by the guardian (operator) of the infant in the stroller 10. For example, the control unit 61 determines whether or not the guardian picks up the object held by the hand by analyzing the captured images of the infant's face and hands captured by the imaging device 41. When determination here is denied, it transfers to step S280, the control part 61 issues a warning from the warning part 62 or the terminal warning part 72, and returns to step S270. In this case, the control part 61 should just issue an alarm by the same method as the alarm (one of step S256 and step S257) performed in the process of FIG. After the process of step S280 is performed, the process returns to step S270. On the other hand, if the determination in step S270 is affirmative, the entire process of FIG.

(Fall prevention processing)
Next, the fall prevention processing will be described along the flowchart of FIG.

  In the process of FIG. 16, first, in step S <b> 310, the control unit 61 determines whether or not the braking device 26 has locked the rear wheel 24. In this case, the determination is affirmed when the operator does not properly hold the handle 50 (for example, when the baby is away from the stroller 10 with the baby on the stroller 10). Note that while the determination in step S310 is negative, step S310 is repeated, and when the determination is positive, the process proceeds to step S312. In step S310, for example, it may be determined whether or not the handle 50 is being gripped.

  In step S312, the control unit 61 detects the position of the center of gravity via the center of gravity detection sensor 32.

  Next, in step S314, the control unit 61 determines whether or not the center of gravity position of the infant has changed. When the infant is sitting on the seat portion 30 in a correct posture, the center of gravity is located near the center of the seat portion 30. However, when the infant leans forward or leans left and right, the position of the center of gravity changes. If the determination is negative, the process returns to step S310. If the determination is positive, the process proceeds to step S316.

  When the process proceeds to step S316, the control unit 61 determines whether or not the detection result (load) of the load sensor 31 has changed greatly by a predetermined value or more. In this case, the control unit 61 determines whether or not the load has changed greatly to the extent that the baby may fall from the stroller 10 or the stroller 10 may fall. If the determination is negative, the process returns to step S310. If the determination is positive, the process proceeds to step S318.

  When the process proceeds to step S318, the control unit 61 issues an instruction to the terminal alarm unit 72 of the terminal 70, and the terminal alarm unit 72 issues an alarm to the operator. Note that the alarm in this case may simply output an alarm sound, but for example, the current state of the infant may be described as “the child may fall down”. Good. Further, if an infant's name is registered in the electronic device 60 in advance, an alarm may be issued such as “There is a possibility that OO (chan's name) may fall down”.

  After step S318, the control unit 61 ends all the processes in FIG.

  As described above in detail, according to the first embodiment, the first to third pressure sensors 52 a to 52 c are provided on the handle 50 of the stroller 10, and when the operator's hand comes into contact with the hand, The contact pressure is detected, and the control unit 61 restricts the operation of the stroller 10 according to the detection results of the first to third pressure sensors 52a to 52c. This restricts the operation of the stroller 10 based on how the handle is held and the attributes of the person holding the handle (adults and children), which can be determined from the contact pressure of the hand. It becomes possible to raise.

  Further, in the electronic device 60 of the first embodiment, the first to third pressure sensors 52a to 52c detect the contact area of the operator's hand, thereby accurately determining whether the control unit 61 is an adult or a child. Judgment can be made.

  In the electronic device 60 of the first embodiment, since the first to third pressure sensors 52a to 52c detect information on both hands, it is possible to accurately determine whether the operator holds the handle 50 in an appropriate state. Judgment can be made.

  In addition, since the electronic device 60 of the first embodiment includes the imaging device 41 that images a part of the stroller 10, it is possible to image an infant in the stroller 10. In the first embodiment, since the control unit 61 can issue an alarm based on the state of the infant imaged by the imaging device 41, it is possible to suppress accidental ingestion of the infant. Further, in the first embodiment, the processing of FIG. 9 is started from the stage where the infant is put on the stroller 10 or the handle 50 is gripped by the operator. It is possible to perform imaging (S211, S231, S251). Thereby, it is possible to reduce useless shooting by the imaging device 41.

  The electronic device 60 of the first embodiment includes a load sensor 31 and a center of gravity detection sensor 32, and the control unit 61 issues an alarm according to the detection result of the load sensor 31 and the center of gravity detection sensor 32, whereby the stroller 10 is provided. It is possible to notify in advance of the fall of the infant to ride and the fall of the stroller 10.

  Further, according to the first embodiment, the operator of the stroller 10 holds the terminal 70, and the control unit 61 issues an alarm from the terminal 70 according to the detection results by the first to third pressure sensors 52a to 52c. I am trying to emit. Thereby, even if the operator is away from the stroller 10, the alarm can be easily noticed.

  In the first embodiment, the case where the control unit 61 maintains the lock of the stroller 10 when the handle 50 is not properly gripped in the safety maintenance process has been described (S134). Instead of this, for example, the control unit 61 may issue an alarm from the alarm unit 62. In the first embodiment, a case has been described in which the control unit 61 issues an alarm when the load changes largely by a predetermined amount or more in the fall prevention processing. Ten wheels may be locked or speed limited.

  In the first embodiment, the size (area) of the operator's hand may be registered in advance. By doing in this way, the fall of the usability by the woman with small hand being misrecognized as a child by the control part 61 can be suppressed.

  In the first embodiment, the case where the lock release switch 27 is provided in the safety maintenance process has been described. However, a limited operation release switch for releasing the speed limit operation is provided together with or instead of this. It is good.

  Note that the processing in FIG. 5 and the processing in FIG. 16 are not limited to the stroller 10 but can be applied to a cart for carrying goods. Therefore, you may make it provide the electronic device 60 of the 1st embodiment in the cart for baggage conveyance.

<< Second Embodiment >>
Next, a second embodiment will be described in detail with reference to FIGS. The second embodiment is different from the first embodiment in that the electronic device 160 is provided in the washing machine 110.

  FIG. 17 schematically shows the configuration of the washing machine 110 according to the second embodiment. The washing machine 110 is assumed to be a general fully automatic drum type washing machine.

  As shown in FIG. 17, the washing machine 110 includes a main body 120, a washing tub 130, a door 140, and a handle 150. In addition, the washing machine 110 is assumed to include a mechanism (for example, a water supply port, a drain port, a drying device, etc.) that realizes various functions of a general washing machine.

  The main body 120 forms an outline of the washing machine 110. The washing tub 130 is disposed inside the main body 120 and is tilted so that the laundry can be easily taken in and out. The door 140 is provided in the vicinity of an opening formed on the front surface of the main body 120 and has a function of opening and closing the opening. The handle 150 is provided above the door 140 of the main body 120. The handle 150 is a rod-shaped member that can be grasped with one hand.

  As shown in the block diagram of FIG. 18, the electronic device 160 provided in the washing machine 110 includes a control unit 161, a pressure sensor 152, a door sensor 141, a water level sensor 132, a door lock mechanism 142, an alarm unit 62, and a communication unit 63. Prepare. The terminal 70 includes a terminal communication unit 71 and a terminal alarm unit 72.

  The control unit 161 comprehensively controls the entire processing executed by the electronic device 160. The control unit 161 is electrically connected to sensors and devices included in the electronic device 160, determines processing contents based on information acquired from the sensors and devices, and instructs the devices to execute the processing. Output.

  The pressure sensor 152 is provided on the handle 150. The pressure sensor 152 acquires information on the contact pressure of the hand when the operator grips it and the contact site. Since the pressure sensor 152 is provided over the entire circumferential direction of the handle 150, it can detect at which position of the handle 150 the operator's hand or finger is in contact.

  The door sensor 141 is a sensor that detects that the door 140 is open. When the door sensor 141 detects that the door 140 is open, the door sensor 141 outputs the detection result to the control unit 161.

  The water level sensor 132 is a sensor that detects the water level in the washing tub 130. Information regarding the water level in the washing tub 130 detected by the water level sensor 132 is output to the control unit 161.

  The door lock mechanism 142 is a mechanism that locks the door 140 in a closed state. When the door lock mechanism 142 is locked, the door 140 cannot be opened.

  The alarm unit 62, the communication unit 63, and the terminal communication unit 71 and the terminal alarm unit 72 included in the terminal 70 are the same as those in the first embodiment.

  Next, processing by the control unit 161 of the electronic device 160 will be described in detail along the flowcharts of FIGS. 19 and 23. The control unit 161 performs two processes in parallel, a door opening restriction process (FIG. 19) and a fall prevention process (FIG. 23).

(Door opening restriction process)
FIG. 19 shows a flowchart of the door opening restriction process. The door opening restriction process of FIG. 19 is a process for allowing only an adult to open the door 140 of the washing machine 110. In the second embodiment as well, as in the first embodiment, an adult is not specifically defined by age, such as “how old or older”, and operates the washing machine 110 safely. A person who is physically and mentally mature.

  Note that the process of FIG. 19 is started when the power of the washing machine 110 is on or off (if the electronic device 160 is energized). Further, the door lock mechanism 142 is assumed to lock the door 140 in a state where the door 140 is closed.

  In the process of FIG. 19, first, in step S <b> 410, the control unit 161 stands by until the operator's hand touches the pressure sensor 152. When the operator touches the pressure sensor 152, the contact pressure is detected by the pressure sensor 152. Therefore, the control unit 161 proceeds to step S412 when the contact pressure detection result is acquired.

  In step S412, the control unit 161 calculates a contact area based on the contact pressure detection result acquired from the pressure sensor 152, and determines whether an adult has touched the handle 150 based on the contact area.

  FIG. 20 shows an adult who tries to open the door 140 of the washing machine 110 (holds the handle 150), and FIG. The child is shown. FIG. 22 (a) shows the state of the hand and the handle when the adult holds the handle 150, and FIG. 22 (b) shows the state of the hand and the handle when the child holds the handle 150. It is shown. As shown in these drawings, when an adult grips the handle 150 of the washing machine 110, the handle 150 is gripped from the upper side of the handle 150, and when a child grips the handle 150, the handle 150 is pressed from the lower side of the handle 150. Hold. Further, since the size of the hand is different between an adult and a child, the area of the area where the hand and the handle 150 come into contact with each other when the handle 150 is gripped (area A in FIGS. 22A and 22B), and The areas of the non-contact areas (area B in FIGS. 22A and 22B) are different. Therefore, the difference between an adult and a child can be determined from the contact area between the hand and the handle 150 and the size of the contact area. Therefore, in this embodiment, in step S412, the control unit 161 calculates the contact area of the handle 150 and the hand, and determines whether the person holding the handle 150 is an adult based on the contact area. I am going to do that.

  When the determination in step S412 is affirmed, the process proceeds to step S414, and the control unit 161 releases the lock of the door 140 by the door lock mechanism 142. On the other hand, when the determination in step S412 is negative, the process proceeds to step S416, and the control unit 161 maintains the lock of the door 140 by the door lock mechanism 142. When the process of step S414 or step S416 is completed, the control unit 161 ends all the processes in FIG.

  As described above, since the child cannot open the door 140 of the washing machine 110 by performing the process of FIG. 19, there is no possibility that the child will fall into the washing tub 130, and safety is maintained.

(Fall prevention processing)
Next, FIG. 23 shows a flowchart of the fall prevention process. This fall prevention process is a process for preventing a child (or pet) from falling into the washing tub 130 and encountering dangerous eyes when an adult leaves the door 140 open.

  Note that the processing in FIG. 23 is started when the power of the washing machine 110 is on or off (if the electronic device 160 is energized), regardless of whether it is off.

  In the process of FIG. 23, first, in step S510, the control unit 161 stands by until the door 140 of the washing machine 110 is opened. Note that the control unit 161 determines whether the door 140 is open based on the output from the door sensor 141. When the door 140 of the washing machine 110 is opened, the process proceeds to step S512. In addition, the washing machine 110 starts counting the opening time of the door 140 in the stage which shifted to step S512.

  If transfering it to step S512, the control part 61 will judge whether predetermined time or more passed since the door 140 opened. Here, it is assumed that the predetermined time is a time required for taking in and out the laundry and can be changed by setting. If the determination in step S512 is negative, that is, if the predetermined time has not elapsed, the process proceeds to step S514. In step S514, the control unit 161 determines whether water is accumulated in the washing tub 130 or not. The control unit 161 determines whether water has accumulated based on the output from the water level sensor 132. If the determination is negative, the process returns to step S510. If the determination is positive, the process proceeds to step S516.

  Note that if the determination in step S512 is affirmative, that is, if a predetermined time or more has elapsed since the door 140 opened, the process proceeds to step S516.

  When the process proceeds to step S516, the control unit 161 instructs the alarm unit 62 and / or the terminal alarm unit 72 to issue an alarm. In this way, it is assumed that the alarm is issued when the door is kept open for a long time (S512: affirmative), and there is a high possibility that the child (or pet) will fall into the washing tub 130, In addition, if the door is opened with water in the washing tub 130, a child (or pet) may fall into the washing tub 130 and drown even in a short time. The alarm may simply sound an alarm sound, for example, the door 140 such as “the door remains open” or “the door is open with water in the washing tub”. You may make it alert | report the state which is open.

  As described above in detail, according to the second embodiment, the pressure sensor 152 provided on the handle 150 of the washing machine 110 detects and controls the contact pressure of the hand when the operator's hand comes into contact. Since the part 161 restricts the opening of the door 140 of the washing machine 110 according to the detection result of the pressure sensor 152, it prevents the child from opening the door 140 of the washing machine 110 and falling to the washing tub 130. can do. In particular, in the washing machine in which the washing tub is obliquely installed as shown in FIG. 17 and the child can easily enter, it is possible to prevent the child from falling into the washing tub or being trapped.

  Further, according to the second embodiment, the control unit 161 causes the alarm unit 62 to issue an alarm according to the detection result of the pressure sensor 152, so that the door 140 of the washing machine 110 is opened to the operator (guardian). By notifying that it is open, it is possible to prevent a child (or pet) from falling into the washing tub 130 in advance.

  Since there may be no small child in the home where the washing machine 110 is installed, the electronic device 160 is provided with a switch for canceling the functions of the electronic device 160 (door opening restriction processing, fall prevention processing). It is good as well.

  In the second embodiment, the size (area) of the operator's hand may be registered in advance. By doing in this way, the fall of the usability by the woman with small hand being misrecognized as a child by the control part 61 can be suppressed.

<< Third Embodiment >>
Next, a third embodiment will be described with reference to FIGS. As shown in FIG. 24, the third embodiment is different from the first and second embodiments in that an electronic device 260 is provided on a bicycle 210.

  As shown in the block diagram of FIG. 25, the electronic device 260 includes a control unit 261, a first pressure sensor 252a, a second pressure sensor 252b, a rotation sensor 262, and an alarm unit 62.

  The control unit 261 comprehensively controls the entire process executed by the electronic device 260. The control unit 261 is electrically connected to sensors and devices included in the electronic device 260, determines processing details based on information acquired from the sensors and devices, and instructs the devices to execute the processing. Output.

  The first pressure sensor 252 a and the second pressure sensor 252 b are provided on the handle 220 of the bicycle 210. Specifically, as can be seen from FIG. 26 where the handle 220 portion of the bicycle 210 is taken out and shown, the first pressure sensor 252a is provided in the right grip portion 221a of the handle 220, and the second pressure sensor 252b is connected to the handle 220. The left grip 221b is provided. The first and second pressure sensors 252a and 252b are provided over the entire circumferential direction of the grip portions 221a and 221b. When a person grips the grip portions 221a and 221b, the first and second pressure sensors 252a and 252b detect that the hand is in contact. The result is output to the control unit 261.

  The rotation sensor 262 is attached to the front wheel or the rear wheel of the bicycle 210, detects the rotation of the front wheel or the rear wheel, and outputs the detection result to the control unit 261.

  The alarm unit 62 is the same as that described in the first embodiment. The alarm unit 62 may be provided at any position on the bicycle 210.

  Next, processing by the control unit 261 of the electronic device 260 will be described in detail with reference to the flowchart of FIG. The process of FIG. 27 is a process for preventing one-handed operation.

  In the process of FIG. 27, first, in step S610, the control unit 261 determines whether the front wheel or the rear wheel is rotating based on the output of the rotation sensor 262. While the determination here is denied, the determination in step S610 is repeated, but if the determination is affirmed, the process proceeds to step S612.

  In step S612, the control unit 261 determines whether the driver of the bicycle 210 is holding the handle 220 with both hands. That is, the control unit 261 determines whether or not the driver's hands are in contact with the grip units 221a and 221b based on the detection results of the first and second pressure sensors 252a and 252b.

  If the determination in step S612 is affirmative, the process returns to step S610. On the other hand, if the determination in step S612 is negative, the process proceeds to step S614 to issue an alarm. The alarm here may simply be an alarm sound, but for example, a message such as “hold the handle with both hands” may be notified. When the process of step S614 is completed, the entire process of FIG.

  As described above in detail, according to the third embodiment, the first and second pressure sensors 252a and 252b provided on the handle 220 (grips 221a and 221b) of the bicycle 210 are connected to the driver's hand. The contact pressure is detected, and the control unit 261 causes the alarm unit 62 to issue an alarm according to the detection results of the first and second pressure sensors 252a and 252b. Thereby, it is possible to prevent the driver of the bicycle 210 from driving with one hand off, and to prevent a bicycle accident from occurring. In this case, as shown in FIG. 28, the general bicycle 280 can be driven with one hand or operated while operating the mobile phone 281 (calling, viewing the screen, etc.). In the form of the bicycle 210, since driving with both hands is forced as shown in FIG. 24, safety can be improved as compared with the case of FIG.

  In the third embodiment, the case where the rotation sensor 262 detects the rotation of the front wheel or the rear wheel of the bicycle 210 has been described. However, the present invention is not limited to this. For example, the rotation of the pedal or the contact between the pedal and the foot May be detected. In addition, in order to exclude that an alarm is issued when the bicycle 210 is pushed by hand, the rotation sensor 262 performs processing / judgment after step S612 in FIG. 27 when the bicycle 210 exceeds a predetermined speed. It may be. Further, the control unit 261 may brake (speed limit) the wheel by the braking device of the bicycle 210 when the handle 220 is not grasped with both hands.

  In the third embodiment, the case where the first and second pressure sensors 252a and 252b are provided on the handle of the bicycle 210 has been described. However, the present invention is not limited to this, and the handle of other vehicles (for example, cars and airplanes) It may be provided on the control stick. Note that in the case of a vehicle in which one-handed driving is less dangerous than a bicycle, an alarm may be issued when a predetermined time has elapsed for one-handed driving.

<< Fourth Embodiment >>
Next, a fourth embodiment will be described with reference to FIGS. 29 schematically shows the mobile device 360, and FIG. 30 shows a block diagram of the mobile device 360.

  As shown in FIGS. 29 and 30, the mobile device 360 includes a mobile device main body 310 and a grip portion 350.

As shown in FIG. 30, the mobile device main body 310 includes a control unit 311, a speaker 312, and a connection terminal 313. Note that the mobile device main body 310 includes a mechanism for realizing various functions of other general mobile devices.

  The control unit 311 comprehensively controls the entire process executed by the mobile device 360. The speaker 312 outputs a sound and an alarm under the instruction of the control unit 311. The connection terminal 313 is a terminal for connecting an external device to the mobile device body 310, and as an example, is assumed to be a USB (Universal Serial Bus) connection terminal.

  The grip portion 350 includes a rod-shaped member 349, a pressure sensor 352 provided on the rod-shaped member 349, and a connection cable 351.

  The rod-shaped member 349 has a length and a diameter suitable for grasping with one hand. The pressure sensor 352 is provided over the entire circumferential direction of the rod-shaped member 349. The pressure sensor 352 detects the pressure (contact pressure) when the operator's hand comes into contact with the grip unit 350 connected to the portable device main body 310, and outputs the detection result to the control unit 311. . The connection cable 351 is a cable for connecting the main body of the grip unit 350 and the mobile device main body 310, and is assumed to be a USB cable as an example.

  Next, the one-handed operation prevention process by the control unit 311 will be described in detail along the flowchart of FIG. As a premise of the processing in FIG. 31, the portable device main body 310 is not connected to the grip unit 350, and the control unit 311 is in a state where the portable device main body 310 is not connected to the grip unit 350. It is assumed that an operation by the operator of the main body 310 is locked (set to a mode in which no operation is accepted).

  In the process of FIG. 31, first, in step S <b> 710, the control unit 311 determines whether or not the grip unit 350 is connected to the mobile device main body 310. If the determination in step S710 is negative, that is, if the grip unit 350 is not connected to the mobile device body 310, the process proceeds to step S712, and the control unit 311 maintains the operation lock of the mobile device body 310. Then, the process returns to step S710. On the other hand, if the determination in step S710 is affirmed, the control unit 311 proceeds to step S714 and releases the operation lock of the mobile device main body 310. That is, the grip part 350 has a function as a key for releasing the operation lock of the mobile device body 310.

  After step S714, in step S716, the control unit 311 waits until the portable device main body 310 is operated by the operator. Then, when the portable device main body 310 is operated by the operator, the process proceeds to step S718, and the control unit 311 determines whether the operator is holding the rod-shaped member 349 based on the output of the pressure sensor 352. To do. If the determination here is affirmed, the control unit 311 does not do anything (without issuing an alarm or the like) and ends the entire process of FIG. That is, as long as the operator holds the rod-shaped member 349, the operator can operate the mobile device main body 310 in the same manner as a normal mobile device (including a call).

  On the other hand, if the determination in step S718 is negative, that is, if the operator does not hold the rod-shaped member 349, the process proceeds to step S720, and the control unit 311 issues an alarm from the speaker 312 and returns to step S718. . In this case, the control unit 311 repeats steps S718 and S720 until the operator grasps the rod-shaped member 349, and thus the alarm is continuously issued from the speaker 312. Thereafter, when the determination in step S718 is affirmed, all the processes in FIG. 31 are terminated.

In step S720, a simple alarm sound may be output from the speaker 312. For example, a message such as “cannot be operated with one hand” may be output.

  By performing the processing of FIG. 31, since the alarm is continuously generated unless the operator who operates the mobile device main body 310 holds the rod-shaped member 349 of the grip portion 350, the operation of the mobile device main body 310 can be comfortably performed. Can not be. That is, when operating the mobile device body 310, both hands of the operator are blocked. Accordingly, for example, it becomes impossible to operate the mobile device body 310 while riding a bicycle or to operate the mobile device body 310 while driving a car. It is possible to prevent an accident from occurring by operating the device main body 310.

  In the fourth embodiment, the case where the grip portion 350 and the mobile device body 310 are separable has been described. However, the present invention is not limited to this, and the connection between the grip portion 350 and the mobile device body 310 is fixed. It may be.

  In the fourth embodiment, the case where an alarm is issued when the operator does not hold the rod-shaped member 349 has been described. However, in conjunction with or instead of this, the operation of the mobile device main body 310 is locked. It is good.

  In order to prevent the driver of the bicycle or automobile from simultaneously grasping the handle of the bicycle or automobile and the grip portion 350 (bar-like member 349) with one hand, the diameter of the grip portion 350 is increased (for example, (φ5 cm or more). For the same reason, the length of the connection cable 351 may be shortened (for example, less than 10 cm).

<< Fifth Embodiment >>
Next, a fifth embodiment will be described in detail with reference to FIGS. In the fifth embodiment, an electronic device 460 shown in FIG. 33 is provided on a track 410 having a loading platform 411 shown in FIG.

  As shown in FIG. 33, the electronic device 460 includes a control unit 461, a pressure sensor 452, an imaging device 421, and an alarm unit 462.

  The control unit 461 comprehensively controls the entire process executed by the electronic device 460. As can be seen from FIG. 34 in which the handle 450 of the track 410 is taken out, the pressure sensor 452 is provided near the 2 o'clock position and the 10 o'clock position of the handle 450 as an example. Note that the pressure sensor 452 may be provided at another position of the handle 450 or at the entire handle 450.

  As shown in FIG. 32, the imaging device 421 is provided on a ceiling portion inside the loading platform 411 of the truck 410 and images the inside of the loading platform 411. The imaging device 421 is, for example, a digital camera or a video camera, and outputs image data obtained by imaging the inside of the loading platform 411 to the control unit 461. The alarm unit 462 has a speaker or the like, and issues an alarm under the instruction of the control unit 461.

  Next, load collapse detection processing by the control unit 311 will be described in detail with reference to the flowchart of FIG. The process of FIG. 35 is a process for detecting the collapse of the load and notifying the driver.

  As a premise of the processing of FIG. 35, it is assumed that luggage 431 and 432 are loaded inside the loading platform 411 of the truck 410. It is assumed that the luggage 431 is one luggage and the luggage 432 is a group of five packages.

  In the process of FIG. 35, first, in step S810, the control unit 461 waits until the handle 450 is gripped by the driver. The control unit 461 determines that the handle 450 is grasped when the contact of the driver's hand is detected by the pressure sensor 452 provided on the handle 450. While the determination in step S810 is negative, the determination in step S810 is repeated. If the determination is affirmative, the process proceeds to step S812.

  In step S812, the control unit 461 acquires image information captured by the imaging device 421.

  Next, in step S814, the control unit 461 analyzes the image information acquired in step S812, and calculates the occupied area of the load inside the loading platform 411 and the shape of the load. The control unit 461 stores information on the calculated luggage occupation area and the shape of the luggage in a built-in memory. Here, the occupied area of the luggage means an area where the luggage hides the floor when viewed from the ceiling. In addition, the shape of the luggage means the shape of the floor that the luggage hides, and when the luggage is placed alone without contacting other luggage, the shape when the luggage itself is viewed from the ceiling side In the case where a plurality of packages are placed as a group of lumps, the whole shape of the group of lumps when viewed from the ceiling side is meant.

  In this embodiment, as an example, as shown in FIGS. 36 (a) to 36 (d), a black and white checkered pattern 412 having a known side is previously drawn on the floor surface of the cargo bed 411, and the luggage is arranged. A reference image obtained by photographing a floor surface that has not been touched is acquired. Then, the control unit 461 calculates the occupied area of the luggage and the shape of the luggage when taken from the ceiling from the difference obtained by comparing the image acquired when the luggage is arranged with the reference image. FIG. 36A shows an example in which the initial state of the baggage is picked up by the imaging device 421. FIGS. 36B to 36D show the collapse of the load and the baggage is scattered. An example in the case where the imaged state is captured by the imaging device 421 is shown.

  Returning to FIG. 35, in the next step S816, the control unit 461 determines whether or not the image information is already stored in the built-in memory of the control unit 461. When judgment here is affirmed, it transfers to step S818. On the other hand, if the determination in step S816 is negative, the process returns to step S812.

  In step S818, the control unit 461 determines whether the occupied area of the load has changed. As can be seen from a comparison between FIG. 36 (a) and FIGS. 36 (b) to 36 (d), when the load collapses, the occupied area of the load changes (from the case of FIG. 36 (a)). 36 (b) to 36 (d), the occupied area of the luggage is larger). As described above, when the occupied area of the luggage becomes large, the determination in step S818 is affirmed, and the process proceeds to step S822. In step S822, the control unit 461 issues a warning to the driver via the warning unit 462. Note that the alarm may simply output an alarm sound. For example, the state of the package may be described as “the package seems to have collapsed”.

  On the other hand, if the determination in step S818 is negative, the process proceeds to step S820 to determine whether the shape of the luggage has changed. For example, when the initial state of the package is the state shown in FIG. 36 (b), the shape of the package changes when the package moves as shown in FIGS. 36 (c) and 36 (d). Thus, when the shape of the load changes, the determination in step S820 is affirmed, and the process proceeds to step S822. In step S822, the control unit 461 issues a warning to the driver via the warning unit 462. In this case as well, the alarm may simply output an alarm sound. For example, the state of the package may be described as “the package seems to be moving.” Since the luggage often moves according to the acceleration / deceleration of the truck, a warning may be issued only when the change in shape becomes larger than a predetermined value.

  After step S822, the entire process in FIG. If the determination in step S820 is negative, it can be said that no cargo collapse has occurred, and the control unit 461 ends all the processes in FIG.

  As described above in detail, according to the fifth embodiment, the pressure sensor 452 provided on the handle 450 of the truck 410 detects the contact pressure of the driver's hand, and the control unit 461 detects the pressure sensor 452. In accordance with the detection result, the inside of the loading platform 411 of the truck 410 is imaged by using the imaging device 421, and an alarm is issued from the alarm unit 62 based on the imaging result (the state of the luggage). The driver can be appropriately notified when it has occurred.

  In the fifth embodiment, a gravity center detection sensor may be installed on the floor surface of the loading platform 411 of the truck 410, and the presence or absence of collapse of the cargo may be determined by detecting a change in the gravity center position of the load. .

  In the fifth embodiment, the case where the pressure sensor 452 is provided on the handle 450 has been described. However, the present invention is not limited thereto, and the pressure sensor 452 is provided on the seat of the truck 410, and the pressure sensor 452 is used.
