Description

  The present invention is provided in an opening / closing means such as a shutter curtain, detects the state of an obstacle sensing device or the like that detects an obstacle existing on or near the moving path during the opening / closing operation, and detects the detection signal. The present invention relates to an opening / closing device having a function of transmitting wirelessly to a control device side.

  Opening and closing device closes the opening by moving the opening and closing members such as shutter curtains installed in the opening of construction and structures including buildings such as houses, buildings, factories, warehouses, garages, etc. in the closing direction It is. The opening / closing device gradually closes and opens the shutter curtain, which is an opening / closing member, from the upper part of the opening. A seat plate switch is provided on the closing tip side of the opening / closing member. If the seat switch touches any obstacle during the opening / closing operation, the control device stops the opening / closing operation of the opening / closing member itself and avoids the avoiding operation according to the obstacle sensing signal in order to avoid the obstacle being caught. The operation of the opening / closing member is controlled to be performed.

  The obstacle detection device is installed on the seat plate of the shutter curtain. When an obstacle is detected, the transmission unit wirelessly outputs a detection signal to the receiving unit on the upper side (such as the shutter case), and performs safety control on the control panel. It is configured to do. Specifically, when an obstacle comes into contact with the sensing body under the seat plate while the shutter curtain is descending, the transmission unit transmits the sensing signal by wireless communication. The sensing element includes a seat plate switch that detects the movement of the sensing piece, a tape switch, and the like. Some receivers receive this sensing signal and output a stop control signal to the control panel to stop the lowering operation of the shutter curtain, or perform an operation of raising the reverse after the stop. In the case of such a switchgear, most of the transmitters are battery-driven, so if the battery voltage drops, the sensing signal cannot be transmitted even if it touches an obstacle, so the battery voltage drops. Japanese Patent Application Laid-Open No. H10-228561 describes a configuration configured to detect the above.

Japanese Patent Publication No. 7-74577

  In the switchgear described in Patent Literature 1, when the voltage of the battery decreases, a state in which the function of the obstacle sensing device does not operate may occur. Further, if such a state continues for a long period of time, the function of the transmission unit does not operate, transmission becomes impossible, and even if a battery voltage drop is detected, there is a possibility that a signal notifying the replacement cannot be transmitted. Further, when the shutter curtain is in a fully closed state for a long period of time, it is conceivable that the battery of the transmitting unit may run out during the fully closed period. Therefore, when installing electrical parts such as obstacle sensing devices on the shutter curtain, which is a moving part, use a power cable instead of a battery for these electrical parts, and use a control cable instead of wireless communication. The power and signal are exchanged reliably in the system. Also, in this case, the power cable and control cable are safely protected and stored in the guiding cable storage member, so that these cables are not disconnected by twisting or friction when the shutter curtain is opened or closed. It is. However, if the opening / closing frequency of the shutter curtain increases, there is a limit to the durability of the cable housing member itself, which makes it difficult to apply the cable to high-speed and high-frequency applications.

  Even when an electric component is mounted on the movable part of the switchgear and operated by a battery, the present invention can prevent the battery from running out, appropriately detect a decrease in the remaining battery level, and improve the safety of the electric component.

In this embodiment, a shutter device that is controlled to be opened and closed vertically will be described as an example of the opening and closing device. FIG. 1 is a diagram illustrating a schematic configuration of a shutter device including an obstacle sensing device. This shutter device is provided in an opening of a building, and basically includes a shutter case 1, a shutter curtain 2, guide rails 3 and 4, a winding shaft 5, a chain 6, a switch 7 such as a motor, and a control device. 8 and a non-contact charging system.

  The guide rails 3 and 4 are provided on both side walls of the opening of the building so as to guide both ends of the shutter curtain 2, and the cross-sectional shape spanned from the lintel portion 9 to the floor surface 21 is substantially U-shaped. It is comprised with the member which has this guide groove. The shutter curtain 2 moves up and down along the guide grooves of the guide rails 3 and 4 to open and close the opening. The winding shaft 5 is rotatably provided in the shutter case 1 and winds up or rewinds the shutter curtain 2. The chain 6 connects a main sprocket provided on the rotary shaft of the opening / closing machine 7 and a driven sprocket provided on the rotary shaft of the winding shaft 5. Accordingly, the rotational driving force of the opening / closing machine 7 is transmitted to the winding shaft 5 side via the chain 6, and when the opening / closing machine 7 rotates, the winding shaft 5 rotates via the chain 6, and the shutter curtain 2 is opened and closed. Is to be controlled.

  The control device 8 is supplied with power via a power supply line (not shown). The control device 8 is directly based on a control signal corresponding to the operation state of each operation button on an operation switch (not shown), or indirectly based on a control signal for disaster prevention at the time of a fire, for example. Then, the rotation of the switch 7 is controlled, and the obstacle avoiding operation is performed by controlling the rotation of the switch 7 based on the obstacle sensing signal from the obstacle sensing device. A typical operation for avoiding an obstacle is to control the shutter curtain 2 so as to stop the lowering operation. In addition, the shutter curtain 2 may be controlled to move up so that the detection signal from the obstacle sensing device is not output after the descent operation is stopped, and other operations such as reducing the descent speed without stopping, etc. You may control so that operation | movement may be performed.

  The control device 8 includes a wireless transceiver 84 and a non-contact charging unit 85. The wireless transceiver 84 performs wireless communication with the wireless transceiver 14 provided on the seat plate 10 side. A transmission medium between the wireless transceiver 84 and the wireless transceiver 14 is light of a predetermined wavelength, radio waves of a predetermined frequency, and the like, and wirelessly transmits an obstacle detection signal, a charge completion signal, a battery life signal, a battery remaining amount signal, and the like. Communicate with. The non-contact charging unit 85 transmits power to and from the non-contact charging unit 15 provided on the seat plate 10. When the shutter curtain 2 is fully opened and the seat plate 10 comes into contact with the lintel unit 9, the shutter curtain 2 is provided at a position closest to the non-contact charging unit 15 provided on the seat plate 10.

  The obstacle sensing device includes photoelectric sensors 11 and 12 that are provided on both sides of the lower side of the front end of the seat plate 10 and that move up and down in conjunction with the seat plate 10. Since the photoelectric sensors 11 and 12 are arranged so as to face each other on the lower side of the seat plate 10, a non-contact type obstacle sensing area is configured on the lower side of the front end portion of the seat plate 10. That is, when there is an obstacle in the obstacle sensing area of the photoelectric sensors 11 and 12, the photoelectric sensors 11 and 12 enter the obstacle sensing state and send an obstacle sensing signal indicating that the obstacle has been detected via the wireless transceiver 14. Output. The battery 13 is composed of a battery or an electric double layer capacitor capable of rapid charge / discharge, and is provided on the upper side of the seat plate 10 to supply electric power necessary for the operation to the photoelectric sensors 11 and 12 and the wireless transceiver 14. The non-contact charging unit 15 charges the battery 13 with the power supplied from the non-contact charging unit 85.

  FIG. 2 is a diagram showing an outline of a control system for the switchgear shown in FIG. 2, the same components as those in FIG. 1 are denoted by the same reference numerals. In FIG. 2, the wireless transceiver 84 and the non-contact charging unit 85 are built in the control device 8. The CPU 81 receives an obstacle sensing signal, a charging completion signal, a battery life signal, a battery remaining amount signal, and the like from the wireless transceiver 84, and controls various operations of the control device 8 based on the signals.

  The non-contact charging system includes a non-contact charging unit 85 provided on the control device 8 and a non-contact charging unit 15 provided on the seat plate 10. As a power supply method from the non-contact charging unit 85 to the non-contact charging unit 15, any one of an electromagnetic induction method, a radio wave method, and an electromagnetic resonance method is used. Further, a method using laser light or a device combined with a solar cell may be used as a power transmission system. Further, a surface LAN or the like that can simultaneously perform data transmission and power transmission under development may be used.

  The rectification unit 15 a rectifies the power received by the non-contact charging unit 15 and supplies the rectified power to the battery 13. The battery 13 is charged by the rectifying unit 15 a and supplies the charged power to the wireless transceiver 14 and the photoelectric sensors 11 and 12. The photoelectric sensor 11 projects inspection light onto the photoelectric sensor 12. The photoelectric sensor 12 receives the inspection light from the photoelectric sensor 11 and outputs a detection signal corresponding to the received light to the wireless transceiver 14. The wireless transmitter / receiver 14 determines whether an obstacle exists in the obstacle sensing area based on the detection signal from the photoelectric sensor 12. When the wireless transceiver 14 detects an obstacle in the obstacle sensing area, the wireless transceiver 14 transmits an obstacle sensing signal indicating that the obstacle has been detected to the wireless transceiver 84. Further, the wireless transceiver 14 detects the charging state and battery life of the battery 13, and when charging is necessary, a charging required signal indicating that charging is required is completed by the non-contact charging system. Is transmitted to the wireless transmitter / receiver 84, and when the battery life is detected based on the voltage value of the battery 13, a battery life signal is transmitted. The life of the battery is determined by looking at the voltage value at 100% charge.

  FIG. 3 is a flowchart showing an example of processing in the closing operation of the switchgear according to this embodiment. When the operation button (close button) is operated, the CPU 81 outputs a drive signal for lowering the shutter curtain 2 to the switch 7. Thereby, the shutter curtain 2 starts to descend. In step S41, in the middle of the descent, the CPU 81 has an obstacle in the obstacle detection area of the seat plate 10 based on whether or not the wireless transceiver 84 has received an obstacle detection signal from the wireless transceiver 14. If it is determined whether there is no obstacle (no), the process proceeds to the next step S42, and if it is determined that there is an obstacle (yes), the closing operation is not performed. When it is determined that there is an obstacle (yes), a voice such as “There is an obstacle, please remove the obstacle” may be notified.

  In step S <b> 42, the CPU 81 determines whether or not the charging of the battery 13 is complete (full charge) based on whether or not the wireless transceiver 84 has received the charging completion signal from the wireless transceiver 14. If it is determined that charging is complete (fully charged) (yes), the process proceeds to the next step S43. If it is determined that charging is not completed (no), the closing operation is not performed. When it is determined that charging is not completed (no), a voice such as “charging is not completed” may be notified.

  In step S43, the CPU 81 determines whether or not the battery 13 has a life as a battery based on whether or not the wireless transceiver 84 has received a battery life signal from the wireless transceiver 14 and has a battery life. If it is determined (yes), the process proceeds to the next step S44, and if it is determined that there is no battery life (no), the process proceeds to step S45. When it is determined that there is no battery life (no), a sound such as “battery is dead” or “replace battery” may be notified.

  In step S44, the CPU 81 executes a lowering process of the shutter curtain 2 according to the operation of the operation button (close button). In step S45, the CPU 81 outputs a drive signal to the switch 7 only during a period in which the operation button (close button) is pressed, and executes a special mode that allows the shutter curtain 2 to descend. In the case of this special mode, the operator is present nearby and sufficient safety can be ensured when the shutter curtain 2 is lowered, so the shutter curtain 2 is lowered as it is. Thus, when the voltage of the battery 13 decreases, the shutter curtain 2 is lowered only during a period in which the operation button (close button) is pressed without performing a continuous closing operation even if the shutter curtain 2 is to be closed. Therefore, the operator knows that the battery 13 is not present because the operation of the shutter is different from the normal operation. In addition, the battery 13 can be prevented from running out of battery, and appropriate battery replacement can be promoted. The wireless transceiver 14 can always transmit a sensing signal when an obstacle is sensed, and the shutter curtain can be sensed when an obstacle is sensed. 2 can be controlled to the safe side.

  In the above-described embodiment, the case where the non-contact charging unit 85 is provided on the upper side of the lintel unit 9 has been described, but the non-contact charging unit 15 is provided in the vicinity of the rail 3 and the non-contact charging unit 84 is provided at the lower end of the rail 3. Further, it may be provided at the upper end, and may be rechargeable when fully opened and fully closed. Further, a non-contact charging unit 85 may be provided at various locations on the rail 3 so that charging is possible even during operation.

  As shown in FIG. 1, the non-contact charging unit 85 is preferably disposed below the winding shaft 5 and in the vicinity of the switch 7, and further, the lower side of the switch 7 and the control device 8. It is more preferable that the position is close to the upper or upper surface of the seat plate 10 from above when the shutter curtain 2 is fully opened. Further, as shown in FIG. 1, the non-contact charging unit 15 is preferably disposed in the vicinity of the battery 13 and the wireless transceiver 14, and is further disposed on the upper portion or the upper surface of the seat plate 10. It is more preferable that the shutter curtain 2 is located at a position approaching or facing below the non-contact charging unit 85 when the shutter curtain 2 is fully opened.

  When the shutter curtain 2 stops in the middle of lowering, the charging state of the battery 13 may be sensed and the shutter curtain 2 may be driven to a position where the non-contact charging unit 85 exists. Alternatively, when the shutter curtain 2 receives a charging request signal wirelessly during the lowering operation, it may be moved upward. The photoelectric sensors 11 and 12 may be operated by receiving power supply only during the closing operation (descent) in order to save the battery 13. In this case, a signal indicating that the closing operation is being performed is fed back from the wireless transmitter / receiver 84 to the wireless transmitter / receiver 14, and the battery is controlled according to the control state of the shutter curtain 2 (stopping, descending, rising). The on / off of power supply to the power supply 13 may be controlled.
