Patent Document 1 describes a switchgear communication device capable of recognizing whether or not a registration mode has been entered based on sound or vibration without visual recognition. According to the one described in Patent Document 1, since the voice output device rings according to the type of registration, the operator is made to recognize whether or not the registration mode has been entered based on the ringing mode without visually recognizing. be able to.
However, when the switchgear communication device (receiver) shifts to the registration mode, the radio wave generated from another remote control transmitter is erroneously received at another site or at the switchgear device installation location, and the switchgear is registered unintentionally. There was a possibility that it would end up.
Furthermore, in the past, there was no function to recognize the number of remote control transmitters currently registered in the receiver, so in order to investigate the number of registered receivers, the receiver itself must be collected and investigated by the manufacturer. However, it took time to analyze it.

The present invention has been made in view of the above points, and provides an open / close control system and an open / close control method capable of preventing an unintended remote control transmitter from being registered in the registration mode of the remote control transmitter. To do.

According to the open / close control system and the open / close control method of the present invention, there is an effect that it is possible to prevent an unintended remote control transmitter from being registered in the registration mode of the remote control transmitter.

It is a figure which shows the schematic structure of the open / close control system of this invention. It is a block diagram which shows the schematic structure of the transceiver of FIG. It is a flowchart which shows an example of the process of newly registering a remote control operation switch in a transmitter / receiver in the open / close control system of FIG. It is a schematic diagram which shows the outline of the process of FIG.

Hereinafter, preferred embodiments of the open / close control system according to the present invention will be described with reference to the accompanying drawings. In this embodiment, a shutter device 10 whose opening and closing is controlled up and down as an opening / closing body means will be described as an example. FIG. 1 is a diagram showing a schematic configuration of an open / close control system of the present invention. The shutter device 10 basically includes a shutter case 11, a shutter curtain 12, guide rails 13, 14, a motor, a shutter drive circuit, an open / close control circuit 15, a transmitter / receiver 16, a wall switch 20, and a remote control operation switch (operator means) 22. It is composed of ~ 24 and so on. In FIG. 1, the motor, the shutter drive circuit, the take-up shaft, the chain, and the like, which are other components, are not shown. A motion sensor may be connected to the shutter device 10.

The shutter case 11 of the shutter device 10 is provided above the opening. The guide rails 13 and 14 are provided on both ends of the opening and the window so as to be in contact with both ends of the shutter curtain, and the cross-sectional shape extending from the lintel to the floor and under the window frame is U-shaped. It is composed of a metal member having a guide groove. The shutter curtain 12 rises and falls along the guide grooves of the guide rails 13 and 14, and performs each operation of opening / closing or halfway stopping (half-opening or half-closing) of the opening and the window. In the present specification, half-open means a state of being stopped in the middle of an open operation, and half-close means a state of being stopped in the middle of a closed operation.

A take-up shaft (not shown) is rotatably provided on both ends of the shutter case 11 to take up and rewind the shutter curtain 12. A chain (not shown) connects a driven sprocket provided on the rotating shaft of the motor and a driven sprocket provided on the rotating shaft of the take-up shaft. Therefore, the rotational driving force of the motor is transmitted to the take-up shaft side via the chain, and when the motor rotates, the take-up shaft rotates via the chain, and each operation of opening / closing / stopping or stopping the shutter curtain 12 is controlled. It is supposed to be done.

Although not shown, the shutter drive circuit is provided in each shutter case 11. The shutter drive circuit has a microcomputer configuration, and power is supplied from the outside via a power supply line. The shutter drive circuit controls the rotation of the motor based on the control signal from the open / close control circuit 15 to control each operation such as opening / closing / stopping or stopping of the shutter curtain 12. An encoder is coupled to the rotation shaft of the motor, detects the rotation position of the motor, and outputs it to the shutter drive circuit. An HA signal (a signal indicating a closed state or an open state) is output based on the rotational position of this motor.

The motor is provided with a current detector that detects a drive current supplied from the shutter drive circuit to the motor, and the value of the detected drive current is fed back to the shutter drive circuit. The shutter drive circuit controls the rotation speed of the motor based on the detection signal indicating the rotation position (shutter position) of the motor output from the encoder and the detection signal indicating the drive current of the motor output from the current detector. .. When the drive current is detected by the current detector, it can be determined that the motor is in the driving state, and when the driving current is not detected at zero, it can be determined that the motor is in the non-driving state.

In this embodiment, a case where a plurality of (three in the figure) remote control operation switches 22 to 24 are registered for the shutter device 10 will be described. As a result, the shutter device 10 is configured to be controllable by the respective remote control operation switches 22 to 24.

In FIG. 1, an antenna connected to a remote control operation switch 22 to 24 is shown on the transceiver 16. The remote control operation switches 22 to 24 are wireless operator means dedicated to the shutter device, which are provided with operation buttons of an open button, a stop button, and a close button. The transceiver 16 of the shutter device 10 and the remote control operation switches 22 to 24 are connected in a predetermined frequency band (for example, 426 [MHz]), and are connected to each other via a predetermined ID. In this embodiment, id22 is assigned to the remote control operation switch 22 as a predetermined ID, id23 is assigned to the remote control operation switch 23, and id24 is assigned to the remote control operation switch 24 as unique remote control IDs. The transmitter / receiver 16 is controlled by using these remote control IDs.

In addition to the remote control operation switches 22 to 24, the shutter device 10 is provided with a wall switch 20 which is a wired operator means in the vicinity of the opening. The wall switch 20 is a wired operator means (dedicated switch) dedicated to the shutter device provided with an open button, a stop button, and a close button, and is originally directly connected to the open / close control circuit 15 of the shutter device 10 to open / close. A control signal corresponding to the operation state of each stop operation button is transmitted to the open / close control circuit 15. The open / close control circuit 15 controls each operation of opening / closing / stopping the shutter curtain 12 according to a control signal corresponding to the operation state of each of these switches. The shutter device 10 can control each operation of opening / closing / stopping of the shutter device 10 according to the operation of the wall switch 20 regardless of the opening / closing control system. The wall switch 20 may be provided with a button for stopping halfway. The transceiver 16 is electrically connected to the open / close control circuit 15 by wire.

FIG. 2 is a block diagram showing a schematic configuration of the transceiver of FIG. 1. As shown in the figure, the transceiver 16 includes a control unit 30, a communication unit 31, a registration switch 32, a transmission / reception lamp 33, an operation lamp 34, and a sounding device 35.
The communication unit 31 is composed of a wireless module that functions as a low power wireless station. The communication unit 31 receives the radio signal from the remote control operation switches 22 to 24, and transmits the received radio signal to the control unit 30. The communication unit 31 transmits the signal generated by the control unit 30 to the remote control operation switches 22 to 24. Examples of the wireless module include a wireless LAN (Wi-Fi) module, a Bluetooth (registered trademark) communication module, a specified low power wireless module, and the like.

The control unit 30 has a microcomputer configuration and operates according to a program stored in advance. In this embodiment, the control unit 30 lights and displays the transmission / reception lamp 33 based on the signal from the communication unit 31. The transmission / reception lamp 33 is a full-color LED that lights up and displays when a signal is received from the remote control operation switches 22 to 24 or when a signal is transmitted to the outside. In this embodiment, the transmission / reception lamp 33 lights and displays in a red light emitting mode when receiving a signal, and lights and displays in a green light emitting mode when the signal is transmitted.

The control unit 30 controls the lighting display state of the operation lamp 34 and controls the sounding of the sounding device 35 according to the type of registration. The operation lamp 34 is composed of one full-color LED that displays (blinks or lights up) in a display mode (light emitting mode) according to the type of registration described later. It should be noted that it may be configured by a plurality of full-color LEDs that are displayed (blinking or lit) according to the type of registration, or may be configured by a 7-segment display. The sounding device 35 sounds a buzzer sound or a beep sound in a mode corresponding to the number of remote control operation switches registered in the control unit 30.

FIG. 3 is a flowchart showing an example of a process of newly registering a remote control operation switch in the transceiver in the open / close control system of FIG. FIG. 4 is a schematic diagram showing an outline of the process of FIG. The ID new registration process executed by the transceiver 16 in FIG. 3 includes new registration for registering the first unit and additional new registration for registering the second and subsequent units. When the on state of the registration switch 32, which is the ID registration operator means provided in the transceiver 16, is maintained for about 3 seconds or longer, the new registration mode is set in which the first unit is registered. Further, when the operation in which the registration switch 32 is turned on three times in a row is executed, that is, when the registration switch 32 is turned on three times within a predetermined time, the second and subsequent units are additionally registered. It becomes a new registration mode.

In step S31, the transceiver 16 emits a number of buzzer sounds corresponding to the number of registered remote control operation switches registered in the transceiver 16 from the sounding device 35 when the new ID registration mode is entered. For example, if the number of registered units is one, "Boo", if there are two units, "Boo Boo", and if there are three units, "Boo Boo Boo". Pronounce regularly. If the number of registered units is 0, the buzzer sound is not sounded, or the buzzer sound is continuously sounded for a predetermined time (about 3 to 5 seconds) like "boooooo". Further, the full-color LED of the operation lamp 34 may be blinked so as to be synchronized with the sound of the buzzer sound. As a result, the number of remote control operation switches currently registered in the transceiver 16 can be recognized audibly and visually. At this time, if a number different from the known registered number is registered, it can be recognized that the number has been registered due to some erroneous operation. In this case, a predetermined number of remote control operation switches can be registered by restarting the registration process from the first new registration.

In step S32, the operator operates the operation button of any of the remote control operation switches 22 to 24 which is the target of new ID registration, so that the control signal corresponding to the remote control ID and the operation button is transmitted to the communication lines 22a, 23a, 24a. Is transmitted to the transmitter / receiver 16. In the figure, it is displayed as if they are transmitting at the same time, but the remote control operation switches 22 to 24 transmit at different timings.

In step S33, it is determined whether or not the remote control ID has been received, and if it has been received (yes), the process proceeds to the next step S34, and if it has not been received (no), this determination process is repeated until the remote control ID is received. .. When the determination process is repeated a predetermined number of times or a predetermined time (for example, about 3 to 5 minutes) has elapsed without receiving the remote controller ID, the loop is exited and the process is forcibly terminated.

In step S34, a buzzer sound is emitted from the sounding device 35 so that the reception strength at the time of receiving the remote control ID can be easily recognized. For example, when the maximum reception strength is 100, the reception strength in the range of 100 to 75 is the first reception strength, the range of 74 to 50 is the second reception strength, and the range of 49 to 25 is the third reception strength, 25 to. The range of 0 is defined as the fourth reception intensity. In the case of the first reception strength, it is 4 times like "Boo Boo Boo Boo", in the case of the 2nd reception strength, it is 3 times like "Boo Boo Boo", and in the case of the 3rd reception strength, it is "Boo Boo Boo". The buzzer sounds twice like "Boo Boo" and once like "Boo" in the case of the fourth reception intensity. The number of buzzer sounds may be the opposite of the above-mentioned case, such as once for the first intensity and four times for the fourth intensity. The reception intensity may be made visible by lighting the four full-color LEDs of the operation lamp 34.

In step S35, it is determined whether or not the value of the reception intensity at the time of receiving the remote control ID is equal to or greater than the predetermined value, and if it is equal to or greater than the predetermined value (yes), the process proceeds to the next step S36, which is smaller than the predetermined value (no). If so, the process proceeds to step S37. In this embodiment, the case of the first reception strength is set to a predetermined value or more, and the cases of the second reception strength, the third reception strength, and the fourth reception strength are determined to be smaller than the predetermined values.

In step S36, since it is determined that the reception strength is equal to or higher than the predetermined value, the remote control ID (id22) transmitted from any of the remote control operation switches 22 to 24 to the transceiver 16 via the communication lines 22a, 23a, 24a. , Id23, id24) are registered as new IDs. As a result, as shown in FIG. 4, any one of id22, id23, and id24 is registered in the transceiver 16. In the case of the new registration mode in which the first unit is registered, if the old remote control ID previously registered exists, the old remote control ID is deleted and the remote control ID received this time is newly registered. In the case of the additional new registration mode for registering the second and subsequent units, the previously registered remote control ID is retained and the remote control ID received this time is newly registered as the additional ID.

In step S37, the sounding device 35 emits a number of buzzer sounds corresponding to the number of registered remote control operation switches currently registered in the transceiver 16 in the ID new registration mode. In the case of the new registration mode in which the first unit is registered by the ID new registration process, the number of registered units is one, and in the case of the additional new registration mode in which the second and subsequent units are registered, the pronunciation processing in step S31 above. The number of registered units should be one more than the number of registered units recognized by the lighting process, so if any other registered number is pronounced or lit, there is a possibility that it was registered by mistake, so one unit. By re-registering from new registration, a predetermined number of remote control operation switches can be registered again.

In step S38, the ID new registration process ends when the registration switch 32 is turned on. Even if the registration switch 32 is not turned on in this step, the process is forcibly terminated when a predetermined time (for example, about 3 to 5 minutes) has elapsed. The end of this registration process may be recognized by the sounding process of the sounding device 35 and / or the display processing of the operation lamp 34.

In the above-described embodiment, the shutter curtain that is extended by the vertical elevating method has been described as an example, but the same applies even if the shutter-shaped opening / closing member is extended by the horizontal pulling method or the horizontal method. Can be applied to. Further, as the opening / closing body device, for example, it can be applied to a shutter device, a window shutter device, a blind device, a roll screen device, a hanging curtain device, a sliding door device, a moving partition device, an awning device, a waterproof plate device, and the like.
