Description

The present invention is, for example, those of the preferred shutter device control system for controlling the shutter device of the shutter device such as a garage.

Conventionally, in this type of invention, there is a garage shutter device described in Patent Document 1. According to this shutter device for the garage, when the engine of the vehicle is started by operating the ignition key at the time of leaving the vehicle, an automatic transmission signal is automatically wirelessly transmitted from the control side wireless device in the vehicle in synchronization with the operation. It The shutter device opens the shutter when the controlled-side wireless device receives the automatic transmission signal, and automatically closes the shutter when the automatic transmission signal is not received due to the vehicle moving away. It should be noted that the automatic transmission signal continues to be transmitted if the ignition key is on.
Further, at the time of storage, when the automatic transmission signal transmitted from the control-side wireless device of the vehicle approaching the shutter device is received by the receiving unit on the shutter device side, the shutter device opens the shutter. When the vehicle enters the garage and the engine of the vehicle is stopped by the return operation of the ignition key, the automatic transmission signal is not transmitted from the control side wireless device. Therefore, the shutter device automatically closes the shutter after a predetermined time when the automatic transmission signal is not received by the control-side wireless device.

The opening/closing device control system 1 includes an opening/closing device 20 that opens and closes an opening 11 of a garage 10 with an opening/closing body 21, and a transmitter that turns on/off transmission of an automatic transmission signal in conjunction with turning on/off of a start switch of a vehicle 30. 40, an internal sensor 22e that outputs a vehicle detection signal when the vehicle 30 in the garage 10 is non-contact sensed, and a vehicle detection signal when the vehicle 30 in a specific area E outside the garage 10 is non-contact sensed. The outside-compartment sensor 22f for outputting is provided, and the opening/closing operation of the opening/closing body 21 is controlled by the control unit of the opening/closing device 20.

  The garage 10 in the illustrated example is formed in a rectangular parallelepiped shape having an opening 11 on the surface on the outdoor side, and is formed on the first floor of a building or the like. A storage portion 22 of the opening/closing device 20 is installed above the opening 11.

  The opening/closing device 20 includes an opening/closing body 21 that opens and closes in a vertical direction so as to partition or open a space, a storage portion 22 that stores or extends the opening/closing body 21 on the opening side, and an opening/closing body 21. And a guide rail 23 that surrounds the end portion in the lateral width direction and guides in the opening/closing direction (see FIG. 2 ).

  The opening/closing body 21 is formed by connecting a seat plate member 21b that is brought into contact with the contact target portion P (floor surface, ground, frame member, etc.) to the lower end side of the opening/closing body main body 21a having a substantially rectangular shape in plan view ( See FIG. 2). The opening/closing body 21 is opened/closed by being wound up and out by a winding shaft 22h (see FIG. 1) in the storage section 22.

  The storage unit 22 includes a storage case 22a having a substantially rectangular parallelepiped shape that is long in the widthwise direction of the opening/closing body, a winding shaft 22h that winds or unwinds the opening/closing body 10 in the storage case 22a, and the winding shaft 22h. An opening/closing device 22b for driving and rotating or braking via a power transmission means (not shown) such as a chain and a sprocket.

  The switch 22b is composed of an electric motor that rotates the winding shaft 22h in the winding direction and the feeding direction, a brake mechanism that brakes the rotation of the electric motor, and the like.

  The control unit 22c is, for example, an electric circuit including a microcomputer, a storage device, a relay circuit, and the like, and operates according to a program stored in advance. The control unit 22c is connected to the receiving unit 22d, the inside sensor 22e, the outside sensor 22f, the open/close position detecting unit 22g, the obstacle sensing device 22i, and the like.

  The reception unit 22d is an electric circuit that receives a transmission signal transmitted from the transmitter 40 and transfers a control command included in the transmission signal to the control unit 22c, and is configured by a specific low power radio module or the like.

The inside sensor 22e is a sensor that senses the vehicle 30 stored in the garage 10 in a non-contact manner and outputs the vehicle detection signal. According to the illustrated example, the sensors 22e are provided on both sides of the vehicle 30 inside the garage 10. It is composed of a photoelectric tube sensor including a light emitting portion and a light receiving portion provided. The in-compartment sensor 22e transmits a vehicle detection signal to the control unit 22c by wire or wirelessly.
As another example of the in-compartment sensor 22e, it is possible to use a non-contact type sensor of another type such as an ultrasonic sensor for vehicles or a magnetic detection type sensor.

The outside sensor 22f is a near-infrared reflection type area sensor that is configured to capture a reflected light of the near-infrared while forming a three-dimensional specific area E by the near-infrared emitted toward the outside of the garage 10. is there. The outside sensor 22f detects that the vehicle 30 has entered the specific area E based on the change in the reflected light, and transmits the vehicle detection signal to the control unit 22c.
In the specific area E, the boundary e1 on the side closer to the opening/closing body 21 is set to be near the outdoor surface of the opening/closing body 21, as shown in FIG. Further, in the specific area E, the boundary e2 on the side away from the switchgear 20 is set so as to be located within the communicable range between the transmitter 40 and the receiver 22d.

  Other examples of the outside sensor 22f include a microwave Doppler type sensor that obtains a sensing signal proportional to the moving speed of the vehicle 30 by comparing the frequencies of the transmitted microwave and its reflected wave, or a curtain-shaped sensor. It is also possible to use a laser type sensor or the like that emits a laser beam and detects a vehicle entering the laser beam.

  The opening/closing position detector 22g is configured by a counter type limit switch that outputs a contact signal when the rotation amount of the output shaft of the switch 22b reaches a predetermined amount. Other examples of the opening/closing position detection unit 22g include an encoder device that counts the rotation amount of the output shaft or the winding shaft 22h, a proximity switch that detects the position of the seat plate member 21b, and the like. It is also possible.

The obstacle sensing device 22i may be any device that senses an obstacle in the opening/closing path of the opening/closing body 21 and transfers the obstacle sensing signal to the control unit 22c.
The obstacle sensing device 22i illustrated in FIG. 2 is provided with a discharge part near the lower end of one guide rail 23 and a catching part for catching near the lower end of the other guide rail 23, and is discharged from the discharge part and caught. It is an infrared sensor adapted to detect obstruction of the path of an obstacle sensing medium (infrared ray in this example) captured by a part.
As another example of the obstacle sensing device 22i, an infrared sensor provided on the lower end side of the opening/closing body 21 or a pyroelectric sensor provided downward on the outer surface of the storage case 22a may be used.

In addition, the transmitter 40 includes a wireless transmission circuit using a specific power-saving wireless system in a case (not shown) that can be attached to and detached from a cigarette lighter socket of the vehicle 30 to supply power from the cigarette lighter socket. When received, the automatic transmission signal including the control signal of the predetermined format is continuously emitted. The control signal includes a unique ID code set for each transmitter 40, a command for starting the opening operation of the switchgear 20, and the like.
When the start switch of the vehicle 30 is turned on, the transmitter 40 operates by receiving power supply from the vehicle 30 and continues to emit the automatic transmission signal. Further, when the start switch of the vehicle 30 is turned off, the vehicle 30 also shuts off the transmission of the automatic transmission signal because the power supply from the vehicle 30 is also cut off.

  In FIG. 2, reference numeral 24 is a push button switch for opening/closing and stopping the opening/closing body 21. The push button switch 24 is installed at a position accessible by a person on the inner wall surface of the garage 10, and is connected to the control unit 22c by wire or wirelessly.

Next, the control operation of the switchgear control system 1 having the above configuration will be described in detail with reference to the flowchart shown in FIG.
First, in the initial state, it is assumed that the opening/closing body 21 is in a fully closed state.
The control unit 22c determines whether or not the vehicle detection signal is input by the internal sensor 22e and the automatic transmission signal is received by the reception unit 22d (step 1), and when both signals are input. For, the process proceeds to step 2, otherwise the process proceeds to step 1a.

  In step 1a, it is determined whether or not the vehicle detection signal is input by the outside sensor 22f and the automatic transmission signal is received by the control unit 22c. If both signals are input, the process proceeds to step 2. If not, go back to step 1.

  In step 2, the opening/closing body 21 is opened by operating the opening/closing device 22b to rotate the winding shaft 22h in the winding direction. The opening operation is stopped when it is determined that the opening/closing body 21 is at the fully open position based on the detection signal from the opening/closing position detector 22g.

Therefore, for example, as shown in FIG. 3B, when the vehicle 30 in the garage 10 is detected by the in-cabin sensor 22e at the time of leaving the vehicle, the engine of the vehicle 30 is started and the transmitter 40 automatically operates. When a transmission signal is emitted and the automatic transmission signal is received by the reception unit 22d, Steps 1 and 2 are executed, and the opening/closing body 21 opens.
Further, for example, as shown in FIG. 4B, at the time of warehousing, the vehicle 30 outside the garage 10 is detected by the outside sensor 22f, and the automatic transmission signal of the transmitter 40 is received by the receiver 22d. Then, step 1a and step 2 are executed, and the opening/closing body 21 opens.

In the next step 3, the input is such Ikoto vehicle sensing signal by the outside-compartment sensor 22f, or on condition that there is no input of the automatic transmission signal by the transmitter 40, and advances the process to step 4.

  In step 4, it is determined whether or not an obstacle is sensed by the obstacle sensing device 22i. If there is no obstacle sensing, the process proceeds to step 5, and if not, the process returns to step 3.

  In step 5, after step 4, it is determined whether or not a predetermined time has elapsed. If the predetermined time has elapsed, the process proceeds to the next step 6, otherwise the process returns to step 3.

  In step 6, the opening/closing body 21 is closed by operating the opening/closing device 22b to rotate the winding shaft 22h in the feeding direction. This closing operation is stopped when it is determined that the opening/closing body 21 is in the fully closed position based on the detection signal of the opening/closing position detection unit 22g or when the obstacle detection device 22i detects an obstacle. Has become.

Therefore, for example, as shown in FIG. 3C, when the vehicle 30 that has exited the vehicle moves out of the specific area E by the outside sensor 22f, steps 3 to 6 are executed, and the obstacles are blocked. The opening/closing body 21 will be closed after a predetermined time when it is confirmed that there is no gap.
Further, for example, as shown in FIG. 4C, when the vehicle 30 that has entered the warehouse stops the automatic transmission signal from the internal sensor 22e by turning off the start switch (ignition key or the like), a failure occurs. After a predetermined time when it is confirmed that there is no object, the opening/closing body 21 is closed.
The predetermined time is appropriately set based on the time taken for the driver inside the vehicle 30 to move out of the vehicle 30 after entering the warehouse.

  Then, after step 6, the processing by the control unit 22c is returned to step 1.

Therefore, according to the switchgear control system 1 having the above configuration, even when the communicable distance between the transmitter 40 and the receiver 22d varies depending on the installation environment of the shutter device when the vehicle 30 leaves the vehicle, the vehicle 30 is in the specific area. By moving away from E, the opening/closing body 21 can be closed.
Further, even when the communicable distance between the transmitter 40 and the receiving unit 22d varies at the time of warehousing, the opening/closing body 21 can be opened by the vehicle 30 entering the specific area E.
Furthermore, even when the vehicle 30 is stored in the vehicle 30, the opening/closing body 21 can be promptly closed.
Therefore, it is possible to improve operability and reliability when the opening/closing device 20 is automatically opened/closed.

Next, another control example (see FIG. 6) by the control unit 22c will be described.
Since the following control example is a partial modification of the flowchart of the above-described control example (see FIG. 5), the modified part will be mainly described in detail, and redundant detailed description will be appropriately omitted.

  In this control example (see FIG. 6), the control unit 22c first waits for the input of the vehicle detection signal by the internal sensor 22e or the input of the vehicle detection signal by the external sensor 22f (step 11), at least. If there is any one input, the process proceeds to the next step 12.

  In step 12, it is determined whether or not the automatic transmission signal is input. If the automatic transmission signal is input, the process proceeds to the next step 13, otherwise the process returns to step 11.

  In step 13, the opening/closing body 21 is opened by operating the opening/closing machine 22b to rotate the winding shaft 22h in the winding direction.

Therefore, for example, as shown in FIG. 3B, when the vehicle 30 in the garage 10 is detected by the in-cabin sensor 22e at the time of leaving the vehicle, the start button of the vehicle 30 is operated and the transmitter 40 is operated. When the transmitted automatic transmission signal is received by the receiving unit 22d, the opening/closing body 21 is opened in steps 11 to 13.
Further, for example, as shown in FIG. 4B, the vehicle 30 outside the garage 10 is detected by the outside sensor 22f, and the automatic transmission signal of the transmitter 40 is received by the receiving unit 22d when entering the garage. Also in this case, the opening/closing body 21 is opened by the steps 11 to 13.

  Then, the control unit 22c performs the same processing as steps 3 to 6 in steps 14 to 17.

  Next, in step 18, it is determined whether or not the vehicle detection signal is input by the in-compartment sensor 22e. If the vehicle detection signal is input, the process proceeds to step 19, and if not, the process proceeds to step 18a. Transition.

  In step 19, a warehousing notification indicating that the vehicle 30 has entered the garage 10 is issued. Further, in step 18a, a departure notification indicating that the vehicle 30 has exited the garage 10 and has moved away is issued.

Specifically, the warehousing notification and the warehousing notification are wireless or wired signals transmitted from the control unit 22c to a notification device in the building in which the switchgear control system 1 is installed.
When the notification device receives the signal, the notification device notifies the person in the building of the entry or exit status by transmitting voice or light, displaying an image, or the like.

  As another example, the steps 18, 18a and 19 may be omitted from the flowchart of FIG. 6 so that the notification is not performed, or the steps 18, 18a and 19 are added to the flowchart of FIG. It is also possible to perform the notification.

  In addition, according to the above-described embodiment, after the opening/closing body 21 is opened, one of the vehicle detection signal from the outside sensor 22f and the automatic transmission signal from the transmitter 40 is not provided. Although the opening/closing body 21 is closed (steps 3, 14), as another example, the opening/closing body 21 can be closed on condition that there is no signal from both of them.

  Further, the present invention is not limited to the above-described embodiments, but can be modified as appropriate without departing from the scope of the invention.
