Description

  The present invention relates to a radio wave wireless communication system installed in a switchgear.

  Conventionally, an electric fire / smoke shutter device that forms a fire / smoke-proof section in this building by fully closing the openings provided in various buildings in the event of a fire has spread. . FIG. 6 is a diagram conceptually showing such a conventional shutter device 100 and a fire alarm system 110 linked to the shutter device. The shutter device 100 is generally configured to include a shutter curtain 101, an opening / closing device 102, an automatic closing device 103, a manual closing device 104, and an interlocking relay 105. On the other hand, the fire alarm system 110 includes a fire detector 111 and a disaster prevention panel 112. In a normal state, the opening / closing button provided on the manual closing device 104 is operated by the user so that the opening / closing machine 102 rotates the winding shaft (not shown) around which the shutter curtain 101 is wound so that the shutter curtain 101 is moved. Raised or lowered by electric drive. Further, when a fire is detected by the fire detector 111, a fire detection signal is output from the fire detector 111 to the disaster prevention panel 112, and a transfer signal is output from the disaster prevention panel 112 to the interlocking relay 105. Then, the automatic closing device 103 releases the brake of the switch 102 based on the control signal from the interlock repeater 105, so that the shutter curtain 101 wound around the winding shaft is lowered by its own weight to prevent fire and smoke. Form a compartment.

  The shutter device 100 is provided with an obstacle detection device (danger prevention device) 120. The obstacle detection device 120 stops the descent of the shutter curtain 101 when the shutter curtain 101 comes into contact with an obstacle when the shutter curtain 101 is lowered by electric or dead weight to close the opening. This is to prevent harming the obstacle. The obstacle detection device 120 is generally configured to include a seat plate switch 121, a signal line 122, and a cord reel 123. The seat plate switch 121 detects that the seat plate 106 provided at the lower end portion of the shutter curtain 101 is in contact with an obstacle, and outputs a detection signal when the contact is detected. The signal line 122 is a line that connects the seat plate switch 121 and the interlock repeater 105 so that wired communication is possible. When the interlock repeater 105 receives the detection signal of the seat switch 121 via the signal line 122 while the shutter curtain 101 is descending, it outputs a control signal to the switch 102 to operate the brake. Then, the descent of the shutter curtain 101 is stopped. The cord reel 123 winds the signal line 122 so that the unwinding length of the signal line 122 is always maintained at an appropriate length even when the seat switch 121 moves up and down as the shutter curtain 101 is opened and closed. Taking up or unwinding is performed (for example, refer to Patent Document 1).

  Furthermore, in recent years, an apparatus that performs radio wave communication has been proposed as an obstacle detection apparatus (see, for example, Patent Document 2). In general, the obstacle detection apparatus includes a transmitter and a receiver in place of the signal line 122 and the cord reel 123 in the configuration of Patent Document 1 shown in FIG. The transmitter is disposed near the seat plate switch 121 in the shutter curtain 101, and transmits an obstacle detection state signal including a detection result of the seat plate switch 121 by radio wave radio. The receiver is arranged in the vicinity of the interlock repeater 105, and outputs an obstacle detection state signal transmitted by the transmitter to the interlock repeater 105.

  As described above, communication methods using a transmitter and a receiver include a method in which only one-way communication from the transmitter to the receiver is performed and a method in which bidirectional communication is performed between the transmitter and the receiver. However, if an obstacle is detected when the shutter curtain is lowered, it is necessary to stop the shutter curtain from falling within a predetermined distance (for example, 5 cm) stipulated by law. Therefore, it is preferable to employ a method for performing bidirectional communication. When performing this two-way communication, it is necessary to accurately identify the other party with which the transmitter and receiver should communicate. Therefore, a transmitter ID for uniquely identifying the transmitter and a receiver ID for uniquely identifying a receiver to be communicated with by the transmitter are registered in the transmitter. In the receiver, a receiver ID for uniquely identifying the receiver and a transmitter ID for uniquely identifying a transmitter to be communicated by the receiver are registered.

  The registration work of the transmitter ID and the receiver ID is performed before the transmitter and the receiver are shipped from the factory, or after the transmitter and the receiver are installed. That is, when a transmitter and a receiver are newly installed, since the transmitter and the receiver are shipped as a pair, a registration operation is performed on the pair of transmitter and receiver before shipment from the factory. In addition, after one of the transmitter and receiver is installed, if one of the transmitter and receiver is replaced due to a failure or the like, registration work is performed for the replaced transmitter and receiver. .

The case where it has been described will be described.

[II] Specific contents of the present embodiment Next, specific contents of the present embodiment will be described.

(Configuration-Shutter device)
First, a configuration of a shutter device to which the radio wave wireless communication system according to the present embodiment is applied will be described. However, the shutter device can be configured in the same manner as in the prior art, and the configuration and processing not specifically mentioned are the same as in the prior art. FIG. 1 is a front view conceptually showing the shutter device 10, the fire alarm system 20, and the shutter obstacle detection system 30 according to the present embodiment.

  This shutter device 10 is an electric fire-proof shutter device that forms a fire-proof section in this building by fully closing the opening 1 provided in the building when a fire breaks out. The shutter curtain 12, the opening / closing device 13, the automatic closing device 14, the manual closing device 15, and the interlocking relay 16 are configured. In the following description, the X direction in FIG. 1 is referred to as the width direction, the Y direction is referred to as the height direction, and the direction orthogonal to the X direction and the Y direction is referred to as the front-rear direction.

  The shutter accommodating portion 11 is a hollow body for accommodating each portion of the shutter device 10, and is attached to a position near the upper end of the opening portion 1. Inside the shutter accommodating portion 11 are accommodated an opening / closing device 13, an automatic closing device 14, an interlocking relay 16, a take-up shaft (not shown), and a receiver 34 described later of the shutter obstacle detection system 30. In the state where the shutter curtain 12 is wound around the winding shaft, the shutter curtain 12 is also housed inside the shutter housing portion 11 together with a transmitter 33 described later of the shutter obstacle detection system 30. A lintel portion (not shown) is formed on the lower surface of the shutter accommodating portion 11 over the entire length in the opening width direction, and the shutter curtain 12 is taken in and out through the lintel portion.

  The shutter curtain 12 is shielding means that brings the opening 1 into a fully open state, a fully closed state, or a state between these two states by being wound or unwound by a winding shaft. Both end portions of the shutter curtain 12 in the width direction are inserted into guide rails 2 provided along the vertical direction at the left and right inner edges of the opening 1, and the inside of the guide rail 2 can be slid in the vertical direction. In addition, the front and rear direction is restricted so as not to drop out of the guide rail 2. A horizontal seat plate 17 is provided at the lower end of the shutter curtain 12, and a seat plate switch 31 described later of the shutter obstacle detection system 30 is attached to the seat plate 17.

  The opening / closing machine 13 is an elevating unit that electrically lifts and lowers the shutter curtain 12 by rotationally driving the winding shaft, and includes a brake (not shown) that brakes the rotation of the winding shaft. The automatic closing device 14 is a means for controlling the lowering of the weight of the shutter curtain 12, and based on a control signal from the interlocking relay 16, the brake is released by pulling the brake lever of the opening / closing device 13, thereby releasing the shutter curtain. The self-weight drop of the shutter curtain 12 is stopped by lowering the weight of the shutter curtain 12 or operating the brake by returning the brake lever of the switch 13 based on the control signal from the interlocking relay 16.

When the shutter curtain 12 is lifted and lowered electrically, the automatic closing device 14 does not operate, and the opening / closing device 13 releases the brake by itself and drives the winding shaft in a predetermined winding direction or feeding direction to thereby release the shutter. The curtain 12 is raised or lowered electrically to fully open or close the opening 1.
On the other hand, by releasing the brake by the automatic closing device 14, the shutter curtain 12 is lowered by its own weight so that the opening 1 is fully closed, or the brake is operated to brake the rotation of the winding shaft, thereby releasing the shutter. The descent of the curtain 12 is stopped.

The manual closing device 15 is an operating means for operating the shutter curtain 12, and includes a lift button for electrically raising the shutter curtain 12, a lower button for electrically lowering, and a stop button for stopping the shutter curtain 12 being lifted and lowered. When the up button, the down button, or the stop button is pressed by the user, an operation signal corresponding to the pressed button is output to the interlocking relay 16 so that the shutter curtain 12 is electrically driven via the switch 13. Ascend and descend, or stop raising and lowering the shutter curtain 12.

In addition, the manual closing device 15 has a recovery button, and when the recovery button is pressed by the user during the weight drop, the weight drop is stopped.

  The interlock repeater 16 is a control means for interlocking each part of the shutter device 10 and is a relay means for interlocking the fire alarm system 20 with the shutter device 10. The interlock repeater 16 is electrically connected to a switchboard 13, an automatic closing device 14, a manual closing device 15, a disaster prevention panel 22 described later of the fire alarm system 20, and a receiver 34 described later of the shutter obstacle detection system 30. Connected. In particular, the interlock repeater 16 outputs a control signal to the automatic closing device 14 so as to lower the weight of the shutter curtain 12 or stop the weight of the shutter curtain 12 from dropping. Further, when the control signal is output to the automatic closing device 14 in this way, the interlock repeater 16 outputs a signal corresponding to the control content to the receiver 34.

  In addition, the shutter housing portion 11 of the shutter device 10 is provided with a lower limit switch (not shown). In this lower limit switch, the lower end of the shutter curtain 12 is positioned on either the upper side or the lower side with respect to a predetermined position (hereinafter referred to as a lower limit position) set at a predetermined distance (several centimeters) above the floor surface. It is a switch for detecting whether or not The lower limit switch includes, for example, a potentiometer that detects the amount of rotation of the winding shaft of the shutter curtain 12 and a counter type limit switch, and the lower end of the shutter curtain 12 is positioned below the lower limit position. If it is, the lower limit signal is output to the interlock repeater 16.

(Configuration-Fire alarm system)
Next, the structure of the fire alarm system 20 linked with the shutter obstacle detection system 30 according to the present embodiment will be described. However, the fire alarm system 20 can be configured in the same manner as in the prior art, and the configuration and processing that are not specified are the same as in the prior art. The fire notification system 20 is a system that detects and notifies the occurrence of a fire in a monitoring area set in a building, and includes a fire detector 21 and a disaster prevention panel 22. The fire detector 21 outputs a fire detection signal to the disaster prevention panel 22 when a fire occurrence in the monitoring area is detected. When the fire prevention signal is received from the fire detector 21, the disaster prevention panel 22 outputs an alarm sound and turns on the fire indicator light, and fully closes the shutter curtain 12 to form a fire prevention zone to spread the fire. In order to prevent expansion, a transfer signal for notifying the occurrence of a fire is output to the interlocking repeater 16.

(Configuration-Shutter obstacle detection system)
Next, the configuration of the shutter obstacle detection system 30 according to the present embodiment will be described. The shutter obstacle detection system 30 is a system that detects an obstacle to the shutter curtain 12 that opens and closes the opening 1 as described above. The shutter obstacle detection system 30 includes a seat plate switch 31 and a radio wave wireless communication system 32. Further, the radio wave wireless communication system 32 includes a transmitter 33 and a receiver 34. Note that the transmitter 33 and the receiver 34 are communication means that perform two-way communication by radio waves, and both are communication means that perform both transmission and reception of signals. For convenience, they are referred to as “transmitter 33” and “receiver 34”, respectively.

(Configuration-Shutter obstacle detection system-Seat switch)
The seat plate switch 31 is an obstacle detection unit that detects that the tip end portion (the seat plate 17 in the present embodiment) at the time of the closing operation of the shutter curtain 12 is in contact with the obstacle. The seat plate switch 31 is configured, for example, in the same manner as in the prior art. When the shutter curtain 12 is closed, the seat plate 17 comes into contact with an obstacle and is lifted up relative to the shutter curtain 12. The displacement is detected mechanically (such as a micro switch), and an output corresponding to the detection result is performed. However, any detection means for detecting an obstacle can be used in place of the seat plate switch 31. For example, an ultrasonic sensor, a capacitance sensor, or an optical sensor can be used rather than the lower end of the shutter curtain 12. It may be detected that there is an obstacle below.

(Configuration-Shutter obstacle detection system-Radio communication system-Transmitter)
The transmitter 33 is a first communication unit that wirelessly transmits a signal (hereinafter referred to as an obstacle detection state signal) including information indicating an obstacle detection state by the obstacle detection unit. FIG. 2 is a block diagram showing an electrical configuration of the transmitter 33. The transmitter 33 includes a vibration sensor 33a, an input unit 33b, an indicator lamp 33c, a registration switch 33d, a first transmission unit 33e, a first reception unit 33f, an antenna 33g, a storage unit 33h, a power supply unit 33i, and a control unit 33j. They are connected as shown in the figure.

The vibration sensor 33a is a specifying unit that specifies that the closing operation of the shutter curtain 12 is activated based on the mechanical operation of the shutter curtain 12, and is fixed to the shutter curtain 12 and mechanically operates the shutter curtain 12. When a vibration is detected, a vibration detection signal is output. Although the specific configuration of the vibration sensor 33a is arbitrary, for example, a piezoelectric acceleration sensor can be used. However, as the specifying means for specifying the closing operation of the shutter curtain 12, a means other than the vibration sensor 33a may be used. For example, a magnet sensor or a capacitance type sensor that detects that the shutter curtain 12 is mechanically displaced. A sensor may be used, or a detector that detects the mechanical rotation of a roller provided on the seat plate 17 so as to contact the guide rail 2 may be used.
The input unit 33b is an input unit that receives an input of the output of the seat plate switch 31, and is configured as an input terminal connected to the output terminal of the seat plate switch 31 via a signal line (not shown), for example.
The indicator lamp 33c is output means for notifying the outside of the transmitter 33 that a signal is being transmitted by the transmitter 33. For example, the indicator lamp 33c is configured as an LED, and the transmitter 33 is not shown. It is arranged so that it can project outside the body.
The registration switch 33d is a registration operation means for registering the receiver 34 with which the transmitter 33 is to communicate, and is configured as a push button switch that performs output according to the pressed state, for example. The registration switch 33d is also used as a test switch for testing the normality of the function of the shutter obstacle detection system 30.

The 1st transmission part 33e is a transmission means which transmits an obstruction detection state signal by the 1st frequency of a predetermined 1st frequency band.
The first receiving unit 33f is a receiving unit that receives a predetermined signal other than the obstacle detection state signal at a second frequency in a predetermined second frequency band.

Here, the first frequency band and the second frequency band will be described.
The first frequency band may be a frequency band in which the obstacle detection state signal can be transmitted. In particular, in the present embodiment, the first frequency band is a frequency band in which the obstacle detection state signal can be continuously transmitted. The “frequency band in which continuous transmission is possible” is a frequency band in which continuous transmission of signals is permitted (not required to pause or stop transmission) according to communication laws and standards. In particular, in the present embodiment, carrier sense is performed at the time of signal transmission in order to prevent signal collision when a plurality of shutter obstacle detection systems 30 are disposed close to the shutter device 10. Use the required frequency band. As the first frequency band that meets such conditions, for example, a 429 MHz band for specific low-power radio stations (specifically, a band of 40 channels at intervals of 12.5 KHz from 429.2500 MHz to 4297375 MHz). is there.
On the other hand, the second frequency band may be a frequency band that can transmit a predetermined signal, but in the present embodiment, a frequency band that allows intermittent transmission is used. In the present embodiment, a frequency band that does not require carrier sense is used for the second frequency band. As the second frequency band that matches such a condition, for example, there is a 315 MHz band (specifically, a band exceeding 312 MHz and not more than 315.25 MHz) for a specific low-power radio station.
In the following, for convenience of explanation, the frequency (first frequency) that is included in the first frequency band and the first transmission unit 33e transmits a signal is “429 MHz”, and is the frequency included in the second frequency band. The frequency (second frequency) at which the first receiving unit 33f receives a signal is referred to as “315 MHz”.

  The antenna 33g is a transmission / reception element that transmits the obstacle detection state signal output from the first transmission unit 33e, or receives a predetermined signal and inputs the signal to the first reception unit 33f. Only one antenna 33g is provided, and this antenna 33g is used for transmission / reception of signals of two frequencies of 429 MHz and 315 MHz. For this reason, the total length of the antenna 33g is determined to be, for example, a predetermined integer ratio of a wavelength of 429 MHz and a predetermined integer ratio of a wavelength of 315 MHz (an antenna 34g of a receiver 34 described later). The same).

The storage unit 33h is a rewritable nonvolatile first storage unit that stores various programs and data necessary to operate the transmitter 33, and is configured as an EEPROM, for example. In particular, the storage unit 33h uniquely identifies the first identification information (hereinafter referred to as transmitter ID) for uniquely identifying the transmitter 33 and the receiver 34 to be communicated with the transmitter 33. The second identification information (hereinafter referred to as receiver ID) is stored one by one at an arbitrary timing such as before factory shipment.

The control unit 33j is a control unit that controls each unit of the transmitter 33, and includes, for example, a CPU that executes a program stored in the storage unit 33h.

(Configuration-Shutter obstacle detection system-Radio communication system-Receiver)
Next, the configuration of the receiver 34 in FIG. 1 will be described. The receiver 34 is a second communication unit that receives an obstacle detection state signal by radio (radio wave). FIG. 3 is a block diagram showing an electrical configuration of the receiver 34. The receiver 34 includes an input unit 34a, an output unit 34b, an indicator lamp 34c, a registration switch 34d, a second reception unit 34e, a second transmission unit 34f, an antenna 34g, a storage unit 34h, a power supply unit 34i, and a control unit 34j. They are connected as shown in the figure.

The input unit 34a is an input unit that receives an input of an output from the interlock repeater 16, and is configured as, for example, an input terminal connected to an output terminal of the interlock repeater 16 via a signal line (not shown).
The output unit 34b is an output unit that outputs an obstacle detection state signal to the interlock repeater 16. For example, the output unit 34b is configured as an output terminal connected to an input terminal of the interlock repeater 16 via a signal line (not shown). ing. Specifically, the output unit 34b sets the resistance value inside the output unit 34b to a resistance value corresponding to the type of signal to be output, thereby changing the current value flowing from the receiver 34 to the interlock repeater 16. Various signals are output to the interlocking repeater 16 by changing.

The indicator lamp 34c is an output means for notifying the outside of the receiver 34 that a signal is being received by the receiver 34. For example, the indicator lamp 34c is configured as an LED capable of projecting with a plurality of display colors. ing.
The registration switch 34d is a registration operation means for registering a combination of the transmitter 33 and the receiver 34 to communicate with each other in the transmitter 33 and the receiver 34, and is configured as a push button switch, for example. ing.
In particular, in the present embodiment, the number of parts of the receiver 34 is reduced by configuring the indicator lamp 34c and the registration switch 34d as an integral display switch. Although the specific attachment method of the indicator lamp 34c and the registration switch 34d configured in this way is arbitrary, for example, when the receiver 34 is fixed to the upper surface of a horizontal plate, It is arranged at a position corresponding to the provided through hole, and the user can operate the registration switch 34d from below the plate, and the user can visually observe the indicator lamp 34c.

The second receiving unit 34e is a receiving unit that receives the obstacle detection state signal in the first frequency band.

The storage unit 34h is a second storage unit that stores various programs and data necessary for operating the receiver 34 in a rewritable manner, and is configured as, for example, an EEPROM. In the storage unit 34h, in particular, the receiver ID of the receiver 34 and the transmitter ID of the transmitter 33 to be communicated with the receiver 34 are each set at an arbitrary timing such as before factory shipment. Is remembered.

The control unit 34j is a control unit that controls each unit of the receiver 34, and includes, for example, a CPU that executes a program stored in the storage unit 34h.

(processing)
Next, processing executed in the shutter obstacle detection system 30 configured as described above will be described. This process is roughly divided into a registration process, a weight drop process, and a test process. Hereinafter, after describing the processes common to these processes, each process will be described in turn. In the following, “step” is abbreviated as “S”. However, since the same processing as that described in Patent Document 1 can be adopted for the dead weight lowering processing and the test processing, for example, only the outline thereof will be described.

  First, “carrier sense”, which is a process common to the processes, will be described. When transmitting a signal via the first transmission unit 33e at 429 MHz, the transmitter 33 performs carrier sensing, thereby identifying an empty channel that can be used for transmission and preventing radio wave collision. Specifically, 40 channels of 429 MHz are set as candidate channels, and one channel is selected from the candidate channels. Then, the first transmitter 33e is once set as a receiving means, the received signal strength of the selected channel is measured, and the selected signal strength is determined by determining whether or not the measured signal strength is equal to or greater than a predetermined threshold. It is determined whether or not the channel is an empty channel. If it is not an empty channel, another channel is selected from the candidate channels, and the empty channel is similarly determined. Thereafter, similarly, the determination is sequentially performed on each candidate channel, the channel first determined to be an empty channel is specified as an empty channel that can be used for transmission, and the carrier sense is terminated. The candidate channels may be limited from 40 channels. For example, for each combination of the transmitter 33 and the receiver 34 (for example, the transmitter ID stored in advance in the storage unit 33h and the registration process) A preset channel is set as a candidate channel for each combination with the receiver ID of the communication partner stored in the storage unit 33h, or a predetermined number (for example, about 3 to 6) of channels is set as a candidate channel. You may do it. Immediately after this carrier sense, a connection request signal is transmitted from the transmitter 33 to the receiver 34 via the specified empty channel, and a connection response signal is transmitted from the receiver 34 that has received this connection request signal to the transmitter 33. Thus, communication between the transmitter 33 and the receiver 34 is established.

  Next, “channel scan” which is a process common to the processes will be described. Since the receiver 34 receives a signal at 429 MHz via the second receiver 34e, the receiver 34 identifies the channel used by the transmitter 33 to transmit the signal at 429 MHz by performing a channel scan, and transmits the signal on the channel. Attempt to receive a signal transmitted from the machine 33. Specifically, one channel is selected from the candidate channels set similarly to the carrier sense of the transmitter 33. Then, it is monitored whether or not the signal can be received via the second receiving unit 34e within a predetermined time by the selected channel. If the signal can be received, the transmitter ID included in the signal is Then, it is determined whether or not it matches the transmitter ID stored in its own storage unit 34h in the registration process described later. If the signal cannot be received within the predetermined time, or if the transmitter ID does not match even if it can be received, another channel is selected from the candidate channels, and signal reception is performed in the same manner. It is determined whether or not there is a match between the transmitter ID and the transmitter ID. Thereafter, in the same manner, each candidate channel is sequentially determined, and the channel determined to contain the matching transmitter ID is identified as the channel used by the transmitter 33 for signal transmission, and the channel scan is completed. To do. In the channel scan before the registration process is performed, the transmitter ID match determination is omitted. In the following description, it is assumed that the receiver 34 always repeats this channel scan unless otherwise specified.

  Next, “intermittent reception”, which is a process common to the processes, will be described. The transmitter 33 monitors whether or not a predetermined intermittent reception timing (for example, every several seconds) has arrived, and if it has arrived, supplies power to the first receiving unit 33f for a predetermined time (for example, several ms). Thus, reception is performed at 315 MHz through the first receiving unit 33f for the predetermined time. The reason why intermittent reception is performed in this way is to reduce battery power consumption required for signal reception. Although details will be described later, if a predetermined condition is satisfied during intermittent reception every few seconds, reception processing is performed with a shorter interval between intermittent receptions. That is, when the output from the vibration sensor 33a provided in the transmitter 33 is turned on, the shutter curtain 12 is descending and there is a high possibility that a signal is transmitted from the receiver 34 to the transmitter 33. 33 makes the interval of intermittent reception shorter than usual. It should be noted that reception may be completely stopped during normal times, and intermittent reception may be started when the output from the vibration sensor 33a is turned on. However, when the shutter curtain 12 descends smoothly, the vibration is vibrated. Since there is a possibility that the sensor 33a cannot detect or a failure may occur in the function of the vibration sensor 33a, the reliability of obstacle detection is further improved by performing intermittent reception regardless of the output from the vibration sensor 33a. I am letting. In the following description, it is assumed that the transmitter 33 constantly repeats this intermittent reception unless otherwise specified.

(Processing-Registration process)
Next, the registration process will be described. 4 and 5 are flowcharts of the registration process. This registration process registers the receiver ID of the receiver 34 to be communicated with the transmitter 33 and registers the transmitter ID of the transmitter 33 to be communicated with the receiver 34. For example, before the factory shipment of the radio wave wireless communication system 32 or immediately after the transmitter 33 or the receiver 34 is replaced after the radio wave radio communication system 32 is installed. Is done. This registration process is configured as a series of processes shown in FIG. 4 and FIG. 5. For convenience of explanation, the registration process will be roughly divided into an activation process, a mode switching process, and an ID registration process.

(Processing-Registration processing-Startup processing)
First, the activation process will be described. This activation process is a process for making the mode switching process executable by activating the transmitter 33 and the receiver 34.

  First, with regard to the receiver 34, the activation process is activated when the user turns on the power of the receiver 34 by a predetermined method. Although a specific method for turning on the power can be determined arbitrarily, the present embodiment employs a structure for supplying power from the interlock repeater 16 to the receiver 34 as described above. The receiver 34 can be turned on by turning on a power switch (not shown) provided in the repeater 16 and turning on the interlock repeater 16. When the power of the receiver 34 is turned on in this way, the control unit 34j sets the operation mode of the receiver 34 to the second normal mode and can switch the operation mode to the second registration mode. (SA1). That is, the operation mode of the receiver 34 includes a second registration mode that is a mode in which the transmitter ID can be registered in the storage unit 34h, a predetermined process based on a signal received from the transmitter 33, and the second registration mode. It is possible to selectively switch to the second normal mode in which processing different from the processing in FIG. 6 is performed. Here, the operation mode of the receiver 34 is set to the second normal mode which is the default, and 2. The normal mode can be switched to the second registration mode. This state continues only for a predetermined time (hereinafter referred to as a first receiver standby time, for example, 5 minutes) after the receiver 34 is powered on. Further, the control unit 34j notifies the user that such a state is continued by a predetermined method (SA2). Although the specific method of this notification is arbitrary, in this Embodiment, it is during the 1st receiver standby time, and until the change to the 2nd registration mode is performed, indicator light 34c is changed. A predetermined color (hereinafter, first display color, for example, green) is blinked at a predetermined interval (hereinafter, first blinking interval).

  On the other hand, for the transmitter 33, the activation process is activated when the user turns on the power of the transmitter 33 by a predetermined method. The specific method for turning on the power can be determined arbitrarily. In the present embodiment, as described above, the power is supplied to the transmitter 33 from the power supply unit 33i as a battery connected to the transmitter 33. By connecting this battery to the transmitter 33, the transmitter 33 can be powered on. When the power of the transmitter 33 is turned on in this way, the control unit 33j sets the operation mode of the transmitter 33 to the first normal mode that is the default, and then sets the operation mode of the transmitter 33 to the first mode. It is set in a state where it can be switched to the registration mode (SB1). That is, the operation mode of the transmitter 33 includes a first registration mode that is a mode in which the receiver ID can be registered in the storage unit 33h, a predetermined process based on a signal received from the receiver 34, and the first registration mode. It is possible to selectively switch to the first normal mode in which processing different from the processing in FIG. 5 is performed. Here, the operation mode of the transmitter 33 is set to the first normal mode which is the default, and the first 1 The normal mode can be switched to the first registration mode. This completes the startup process.

(Processing-Registration processing-Mode switching processing)
Next, the mode switching process will be described. This mode switching process is a process for switching the operation mode of the transmitter 33 from the first normal mode to the first registration mode and switching the operation mode of the receiver 34 from the second normal mode to the second registration mode. It is executed continuously after the startup process is completed.

  First, in the receiver 34, the control unit 34j monitors whether or not the receiver 34 is operated by a user in a predetermined method before the first receiver standby time elapses (SA3 and SA4). The specific content of the operation by the predetermined method can be arbitrarily determined in advance. For example, the registration switch 34d is continuously pressed for a predetermined time (hereinafter, the first receiver operation time, for example, 3 seconds) or more. In this case (hereinafter, when the first receiver operation is performed), it is assumed that the receiver 34 is operated by the user in a predetermined method. When the first receiver standby time elapses before this operation is performed (SA3, Yes), the control unit 34j ends the mode switching process and ends the registration process. In this case, in order to start the registration process again, the user, for example, restarts the start process from the beginning (that is, by turning the interlock repeater 16 off and then on again) Cycle power).

  Alternatively, when the first receiver operation is performed before the first receiver standby time elapses (SA3, No, SA4, Yes), the control unit 34j sets the operation mode of the receiver 34 to the second registration mode. Switch (SA5). That is, the receiver 34 performs a predetermined process related to registering the transmitter ID in the storage unit 34h only when the operation mode of the receiver 34 is switched to the second registration mode. The “predetermined process relating to registering the transmitter ID in the storage unit 34h” means a process of fully registering the transmitter ID in SA11 described later in the present embodiment. In addition, when the operation mode of the receiver 34 is switched to the second registration mode, the receiver 34 transmits a signal including the receiver ID stored in the storage unit 34h. “Send a signal including the receiver ID stored in the storage unit 34h” means transmitting a signal including the receiver ID in SA12 described later. However, regardless of whether the operation mode is the second registration mode or the second normal mode, the receiver 34 includes its own receiver ID in the signal transmitted by itself. In addition, the control unit 34j notifies the user that the switching to the second registration mode has been performed (SA6). Although the specific method of this notification is arbitrary, in the present embodiment, the indicator lamp 34c is set to a predetermined color (for example, the first display color) at a predetermined interval (hereinafter, second flashing) different from the first flashing interval. Blink at an interval (for example, an interval faster than the first blinking interval).

  On the other hand, in the transmitter 33, the control unit 33j monitors whether or not the transmitter 33 is operated by the user in a predetermined method (SB2). The specific content of the operation by this predetermined method can be arbitrarily determined in advance. For example, the registration switch 33d is continuously pressed for a predetermined time (hereinafter, first transmitter operation time, for example, 3 seconds) or more. In this case (hereinafter, when the first transmitter operation is performed), it is assumed that the transmitter 33 is operated by the user in a predetermined method. When the first transmitter operation is performed (SB2, Yes), the control unit 33j switches the operation mode of the transmitter 33 to the first registration mode (SB3). That is, the transmitter 33 performs main registration of the receiver ID in SB6 described later only when the operation mode of the transmitter 33 is switched to the first registration mode.

  Next, the control unit 33j transmits a signal including the transmitter ID of the transmitter 33 preset in the storage unit 32h (SB4). Specifically, the control unit 33j specifies a free channel that can be used for transmission by performing carrier sense at 429 MHz via the first transmission unit 33e. Then, when the vacant channel can be specified, the control unit 33j transmits a signal including the transmitter ID stored in advance in the storage unit 33h at 429 MHz via the first transmission unit 33e.

  On the other hand, in the receiver 34, the control unit 34j monitors reception of the signal transmitted from the transmitter 33 (SA7). Specifically, since the control unit 34j receives a signal via the second reception unit 34e at 429 MHz, the channel 33 performs a channel scan to identify the channel used by the transmitter 33 to transmit the signal at 429 MHz. Attempt to receive a signal transmitted from the transmitter 33 in the channel. When this signal is received (SA7, Yes), the control unit 34j temporarily registers the transmitter ID included in the received signal in the storage unit 34h (SA8). That is, in the present embodiment, the receiver 34 does not perform final registration of the transmitter ID in the storage unit 34h (hereinafter referred to as main registration) just by receiving the transmitter ID once. Only temporary registration (hereinafter, provisional registration) is performed. Only when the same transmitter ID is continuously received a predetermined number of times (hereinafter, the same number of reception times, for example, twice), the transmitter ID is fully registered in the storage unit 34h. As a result, for example, it is possible to reduce the possibility of erroneously registering the transmitter ID transmitted from the radio wave communication system of another shutter device installed in the vicinity. In addition, “when the same transmitter ID is continuously received a predetermined number of times” can be paraphrased as the case where the same transmitter ID is provisionally registered continuously for a predetermined number of times. When it is necessary to receive a signal a plurality of times in order to perform the above, it means that the reception of the plurality of times is set as one set, and a predetermined set of reception is continuously performed.

  The control unit 34j notifies the user that the transmitter ID has been temporarily registered (SA9). Although the specific method of this notification is arbitrary, in the present embodiment, the control unit 34j displays the indicator lamp 34c in a color different from the first display color (hereinafter, second display color; for example, red). After lighting for a predetermined time (for example, 3 seconds), the display is returned to blinking at the second blinking interval in the first display color. This completes the mode switching process.

(Processing-Registration process-ID registration process)
Next, the ID registration process will be described. In this ID registration process, the receiver ID of the receiver 34 to be communicated with the transmitter 33 is fully registered, and the transmitter ID of the transmitter 33 to be communicated with the receiver 34 is registered. Is registered continuously, and is continuously executed after the mode switching process is completed.

  First, in the transmitter 33, the control unit 33j monitors reception of a signal transmitted from the receiver 34 after SB4 described above (SB5). If this signal cannot be received (SB5, No), the process returns to SB2 to monitor again whether or not the transmitter 33 has been operated by the user in a predetermined method (SB2). And when 1st transmitter operation is performed (SB2, Yes), the control part 33j is a signal containing transmitter ID of the said transmitter 33 preset by the memory | storage part 32h similarly to SB4 mentioned above. Is transmitted (SB4). Similarly, the control unit 33j transmits a signal including the transmitter ID every time the transmitter 33 is operated by the user in a predetermined method until the signal transmitted from the receiver 34 can be received.

  On the other hand, in the receiver 34, the control unit 34j temporarily registers in the storage unit 34h whether or not the transmitter ID included in the signal received in SA7 has been continuously received more than the same number of times after SA9. Judgment is made with reference to the transmitted transmitter ID (SA10). And when it determines with not having received continuously more than the same frequency | count (SA10, No), the control part 34j returns to SA7, and it received the said every time similarly after receiving a signal from the transmitter 33 similarly. It is determined whether or not the transmitter ID included in the signal has been received continuously for the same number of receptions or more. In addition, before receiving the same transmitter ID continuously for the same number of times or more, if a signal including a different transmitter ID is received, the different transmitter ID is newly temporarily registered in the storage unit 34h, Thereafter, in SA10, it is determined whether or not the different transmitter IDs are continuously received for the same number of times or more.

  And when it determines with having received continuously more than the same reception frequency (SA10, Yes), the control part 34j fully registers the said transmitter ID in the memory | storage part 34h (SA11). In addition, when the transmitter ID is fully registered in SA11 as described above, the control unit 34j transmits a signal including the receiver ID of the receiver 34 preset in the storage unit 34h (SA12). Specifically, the control unit 34j transmits a signal including the receiver ID at 315 MHz via the first transmission unit 34e. In other words, the control unit 34j automatically transmits a signal including the receiver ID without receiving an operation by the user, with the main registration of the transmitter ID as a trigger. For this reason, it becomes possible to abbreviate | omit the operation by the user regarding transmission of receiver ID. Next, the control unit 34j switches the operation mode of the receiver 34 from the second registration mode to the second normal mode (SA13), and prepares for each process after the registration process.

  On the other hand, in the transmitter 33, when the control unit 33j receives a signal transmitted from the receiver 34 after SB4 described above (SB5, Yes), the storage unit 33h stores the receiver ID included in the received signal. (SB6). Next, the control unit 33j switches the operation mode of the transmitter 33 from the first registration mode to the first normal mode (SB7), and prepares for each process after the registration process. This completes the ID registration process, and the registration process ends.

  After this registration processing, the receiver 34 receives the transmitter ID from the transmitter 33 only when the transmitter ID included in the signal received from the transmitter 33 matches the transmitter ID registered in its own storage unit 34h. The received signal is processed as a valid signal. Similarly, the transmitter 33 received from the receiver 34 only when the receiver ID included in the signal received from the receiver 34 matches the receiver ID registered in its own storage unit 33h. Process the signal as a valid signal. Accordingly, for example, it is possible to prevent the shutter device from malfunctioning based on a signal transmitted from a radio wave communication system of another shutter device installed in the vicinity.

(Processing-Weight drop processing)
Next, the dead weight lowering process will be described. This dead weight lowering process is a process for lowering the shutter curtain 12 when necessary. For example, when a fire is detected by the fire detector 21 of the fire alarm system 20 shown in FIG. 1, the fire detector 21 outputs a fire detection signal to the disaster prevention panel 22, and the disaster prevention panel 22 is transferred to the interlock repeater 16. The interlock repeater 16 outputs an activation signal to the automatic closing device 14, and the automatic closing device 14 releases the brake of the opening / closing device 13 and starts the weight drop of the shutter curtain 12. At the same time, the interlock repeater 16 outputs a start-on signal to the receiver 34 to notify that the self-weight drop of the shutter curtain 12 has been started. When this activation on signal is received via the input unit 34a of the receiver 34, the control unit 34j of the receiver 34 transmits the activation on signal at 315 MHz via the second transmission unit 34f.

  On the other hand, when the shutter curtain 12 starts to lower its own weight, the vibration sensor 33a that detects the vibration of the shutter curtain 12 that is generated along with the lowering of its own weight outputs a vibration detection signal. When this vibration detection signal is output, the control unit 33j of the transmitter 33 tries to quickly receive the signal from the receiver 34. When the activation on signal cannot be received within a predetermined time, the control unit 33j causes the vibration detected by the vibration sensor 33a to be caused by an earthquake, a wind, or the like, and caused by the descent of the shutter curtain 12. If not, the process ends. On the other hand, when the activation on signal can be received within the predetermined time, the control unit 33j assumes that the vibration detected by the vibration sensor 33a is caused by the descent of the shutter curtain 12, and transmits the transmitter information signal (obstacle). (Detection state signal) is generated and transmitted to the receiver. The transmitter information signal includes data indicating whether the output from the seat plate switch 31 is a seat plate switch-off output or a seat plate switch-on output, a transmitter ID set in the storage unit 33h, and the like. At this time, by continuously transmitting the transmitter information signal, the descent of the shutter curtain 12 at the time of obstacle detection is stopped as early as possible.

  On the other hand, the control unit 34j of the receiver 34 monitors data corresponding to the output of the seat plate switch 31 included in the transmitter information signal at each time point, and from the seat plate switch 31 during the predetermined time of reception. When the data indicating that the output is a seat plate switch-on output is received, the seat plate switch-on signal is output to the interlocking relay 16 by switching the resistance value inside the output unit 33b. The interlock repeater 16 that has received the seat plate switch-on signal controls the weight drop of the shutter curtain 12 based on the detection state of the lower limit switch and the presence or absence of a power failure in the shutter device 10 specified by a known method. . Specifically, when the lower limit switch detects that the lower end of the shutter curtain 12 is located above the lower limit position, and the shutter device 10 is not out of power, it automatically closes. A control signal is output to the device 14, the automatic closing device 14 activates the brake of the switch 13 to stop the weight drop of the shutter curtain 12 once, drives the switch 13 to raise it for a predetermined time, and then stops. Perform operation (touch-up operation). Alternatively, when the lower limit switch detects that the lower end of the shutter curtain 12 is located above the lower limit position, and the shutter device 10 is out of power, the automatic closing device 14 is used. A control signal is output, and the automatic closing device 14 operates the brake of the switch 13 to temporarily stop the weight drop of the shutter curtain 12 (touch stop operation). On the other hand, when it is detected by the lower limit switch that the lower end of the shutter curtain 12 is located below the lower limit position, the shutter curtain 12 can be controlled regardless of whether or not the shutter device 10 is out of power. After a predetermined time has elapsed after the lower end has passed the lower limit position, a control signal is output to the automatic closing device 14, and the automatic closing device 14 activates the brake of the switch 13 to stop the weight drop of the shutter curtain 12 ( Complete stop operation). By performing such processing, it is possible to prevent the user or the like from being harmed by the lowering of the shutter curtain 12.

  In addition, when an obstruction is removed and the seat plate switch-off output is input from the seat plate switch 31, this state is transmitted from the transmitter 33 to the receiver 34, and the descent of the shutter curtain 12 is resumed. Is done. That is, when the control unit 33j of the receiver 33 receives a transmitter information signal including data indicating that the output from the seat plate switch 31 is a seat plate switch-off output, the internal resistance of the output unit 33b. By switching the value, a seat plate switch-off signal indicating that the obstacle has been removed is output to the interlock repeater 16. Upon receiving this seat plate switch-off signal, the interlock repeater 16 outputs a control signal to the automatic closing device 14 after a predetermined time has elapsed when the person who is caught can evacuate from the shutter curtain 12 with certainty. Releases the brake of the opening / closing machine 13 and resumes the weight drop of the shutter curtain 12 again. However, the lowering is resumed only after the touch-up operation or the touch stop operation, and not after the complete stop operation. Thereafter, the descent stop process and the descent restart process are repeated according to the output of the seat plate switch 31 as described above.

(Processing-Test processing)
Next, the test process will be described. This process is a process for performing a test on the normality of the functions of the transmitter 33 and the receiver 34, and is activated at an arbitrary timing by a user operation. First, the controller 33j of the transmitter 33 determines whether or not the registration switch 33d of the transmitter 33 has been operated by a user in a predetermined method (this is an operation by a method different from the first receiver operation. For example, the registration switch 34d Whether or not it has been pressed for less than the first receiver operation time) is monitored, and if operated, a transmitter information signal including data indicating a seat plate switch-on output is generated, and this transmitter information The signal is continuously transmitted for a predetermined time through the first transmission unit 33e on an empty channel at 429 MHz. As a result, in the above-described weight drop processing, the control unit 34j of the receiver 34 is controlled in the same manner as when the transmitter information signal indicating that the output from the seat plate switch 31 is the seat plate switch-on output is transmitted. The descent of the shutter curtain 12 is stopped. Therefore, it is possible to monitor whether or not the descent of the shutter curtain 12 is normally stopped at the time of construction or periodic inspection, and it is possible to perform a test on the normality of the functions of the transmitter 33 and the receiver 34. become.

(Effect of this embodiment)
According to the radio wave wireless communication system according to the present embodiment, by performing the first transmitter operation, the transmitter ID is registered in the storage unit 34h and the receiver ID is registered in the storage unit 33h. As described above, the transmitter ID and the receiver ID can be registered by performing a single operation. Therefore, the transmitter ID and the receiver ID are individually operated as in the past. Compared to the case where the transmitter ID and the receiver ID are registered, the registration work of the transmitter ID and the receiver ID can be omitted, and the efficiency and time of the registration work of the transmitter ID and the receiver ID can be reduced. In addition, since the registration work of the transmitter ID and the receiver ID can be omitted in this way, the possibility of a work error occurring during the registration work can be reduced, and the transmitter ID and the receiver ID are erroneously registered due to the work mistake. It is possible to reduce the possibility of the occurrence.

  According to the radio wave radio communication system according to the present embodiment, the receiver 34 transmits the receiver ID when the transmitter ID is registered in the storage unit 34h. Thus, when registering the other party's transmitter ID, that is, when confirmation of registering the other party's transmitter ID is obtained, the other party's transmitter is transmitted by transmitting a signal including its own receiver ID. The possibility of erroneously registering the receiver ID can be reduced as compared with the case where a signal including the receiver ID is transmitted before confirmation of registering the ID is obtained.

  According to the radio wave wireless communication system according to the present embodiment, the transmitter ID is registered in the second storage unit 34h when the same transmitter ID is continuously received a predetermined number of times. When registering the transmitter ID after confirming that the same transmitter ID has been continuously received a predetermined number of times in this way and registering immediately after receiving the transmitter ID first In comparison, the possibility of erroneously registering the transmitter ID can be reduced.

  According to the radio wave wireless communication system according to the present embodiment, the predetermined process relating to registering the transmitter ID in the storage unit 34h only when the operation mode of the receiver 34 is switched to the second registration mode. Is done. Alternatively, only when the operation mode of the transmitter 33 is switched to the first registration mode, a predetermined process related to registering the receiver ID in the storage unit 33h is performed. In this way, only when the operation mode is switched to the registration mode, registering the transmitter ID and the receiver ID, compared to registering the transmitter ID and the receiver ID regardless of the operation mode. The possibility of erroneous registration of the transmitter ID and the receiver ID can be reduced.

  According to the radio wave wireless communication system according to the present embodiment, when the registration switch 33d that receives a test request is operated by a predetermined operation method, the operation mode is switched to the first registration mode and the transmitter ID is set. Since it is transmitted, it is possible to simplify the configuration of the transmitter 33 as compared with the case where the operation means for receiving the test request and the operation means for switching the operation mode to the first registration mode are individually provided. It becomes possible.

  According to the radio wave radio communication system according to the present embodiment, when the registration switch 34d is operated by a predetermined operation method within a predetermined time after the power supply to the receiver 34 is turned on, the operation mode of the receiver 34 is the first. 2 is switched to the registration mode, so that the operation mode of the receiver 34 is erroneously changed to the second registration mode as compared with the case where the operation mode of the receiver 34 is switched to the second registration mode regardless of the elapsed time after the power is turned on to the receiver 34. The possibility of switching to the two registration mode can be reduced, and the possibility of erroneously registering the transmitter ID in the second registration mode can be reduced.

[III] Modifications to the Embodiments Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention are within the scope of the technical idea of each invention described in the claims. Can be arbitrarily modified and improved. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above-described contents, and the present invention solves the problems not described above or has the effects not described above. There are also cases where only some of the described problems are solved or only some of the described effects are achieved. For example, even if the registration work of the transmitter ID and the receiver ID cannot be performed in a shorter time than before, if this registration work can be achieved by means different from the conventional work, the problem of the present application is solved. Yes.

(Use of obstacle detection results)
In the above embodiment, the shutter lowering control is performed based on the detection result by the radio wave radio communication system 30 of the switchgear, but this detection result may be used for other purposes. For example, if the shutter device is intended to prevent people from entering the security zone and it is a lightweight shutter device, it is unlikely to cause any harm to an obstacle. Even if an obstacle is detected by the communication system 30, the shutter curtain descent may not be stopped, and only the transfer output to the security system may be performed.

(About transmitter configuration)
In the above embodiment, an example in which the registration switch 33d of the transmitter 33 also serves as a test switch has been described, but these may be provided individually. Further, the registration switch 33d and the indicator lamp 33c may be integrated.

(About the receiver configuration)
In the above embodiment, the example in which the registration switch 34d and the indicator lamp 34c of the receiver 34 are integrated has been described, but these may be provided individually.

(About frequency band selection)
For the first frequency band and the second frequency band, a frequency band other than the frequency band exemplified in the above embodiment may be selected. For example, when transmitting an obstacle detection state signal from the transmitter 33 to the receiver 34, if it is not necessary to perform continuous transmission, a frequency band in which continuous transmission cannot be performed (after performing transmission for a certain period of time, The first frequency band may be selected as the first frequency band). Further, unlike the case where the shutter device 10 is installed alone, there is no possibility that the signals of the radio wave radio communication system 30 of the opening / closing device provided in each of the plurality of shutter devices 10 may interfere with each other. In this case, carrier sense at the time of signal transmission from the receiver 34 to the transmitter 33 may be omitted, and a frequency band for which carrier sense is not required may be selected as the first frequency band.

(About the number of frequency bands)
In the above embodiment, the transmitter 33 is provided with the first receiver 33f and the first transmitter 33e, and the receiver 34 is provided with the second receiver 34e and the second transmitter 34f. By performing communication using the first frequency band and the second frequency band via the unit, communication is performed in 2 systems × 2 frequency bands. However, more than 2 communication systems may be provided, A number of frequency bands exceeding the frequency band may be used. For example, as a system for transmitting a signal from the receiver 34 to the transmitter 33, a system for transmitting an obstacle detection state signal and a system for transmitting battery consumption may be provided separately as dedicated systems, which are different from each other. You may transmit in a frequency band. Alternatively, the first frequency band and the second frequency band may be the same frequency band without being different frequency bands.

(Registration process-modification 1)
In the above embodiment, even if the receiver 34 receives a signal including the transmitter ID, the receiver 34 only performs temporary registration of the transmitter ID until the same transmitter ID is received the same number of times. The transmitter ID is fully registered only when the transmitter ID is continuously received the same number of times. However, provisional registration may be omitted, and the transmitter ID may be fully registered when the transmitter ID is first received. Alternatively, in the above embodiment, when the transmitter 33 first receives the receiver ID, the transmitter 33 is fully registered, but until the same receiver ID is received by the same number of receptions. May only perform provisional registration of the receiver ID, and perform the main registration of the receiver ID only when the same receiver ID is continuously received the same number of times.

(Registration process-modification 2)
In the above embodiment, the receiver 34 transmits a signal including the receiver ID when the transmitter ID is fully registered. However, the receiver 34 transmits a signal including the receiver ID at another timing. Also good. For example, a signal including the receiver ID may be transmitted when the transmitter ID is provisionally registered or when the receiver 34 is operated in a predetermined method.

(Registration process-modification 3)
In the registration processing described in the above embodiment, the operation and processing of the transmitter 33 and the operation and processing of the receiver 34 may be interchanged with respect to part or all of them. For example, when replacing all of them, as a starting process, after the transmitter 33 is turned on, the transmitter 33 is set to the first normal mode, and the first normal mode is set to the first registration mode. The switchable state is continued for the first receiver standby time. On the other hand, after the receiver 34 is turned on, the operation mode of the receiver 34 is set to the second normal mode, and then the second normal mode is set to a state that can be switched to the second registration mode (SB1). Then, as the mode switching process, when the registration switch 33d of the transmitter 33 is operated by the first receiver, the operation mode of the transmitter 33 is switched to the first registration mode. On the other hand, when the registration switch 34d of the receiver 34 is operated by the first transmitter, the operation mode of the receiver 34 is switched to the second registration mode, and a signal including the receiver ID is transmitted from the receiver 34. That is, in this case, the transmitter 33 performs a predetermined process related to registering the receiver ID in the storage unit 33h only when the operation mode of the transmitter 33 is switched to the first registration mode. . The “predetermined process regarding registering the receiver ID in the storage unit 33h” means a process of registering the receiver ID. Further, when the operation mode of the transmitter 33 is switched to the first registration mode, the transmitter 33 transmits a signal including the transmitter ID stored in the storage unit 33h. “Transmit a signal including the transmitter ID stored in the storage unit 33h” means transmitting a signal including the transmitter ID as described below. However, regardless of whether the operation mode is the first registration mode or the first normal mode, the transmitter 33 includes its own transmitter ID in the signal transmitted by itself. Then, as the ID registration process, when the transmitter 33 receives the same receiver ID continuously for the same number of receptions, the transmitter 33 fully registers the receiver ID in the storage unit 33h and sends a signal including the transmitter ID. Send. The receiver 34 fully registers this transmitter ID in the storage unit 34h.

(Registration process-modification 4)
In the above embodiment, the operation on the receiver 34 may be omitted. For example, the operation mode of the receiver 34 is always set to the second normal mode. In the second normal mode, when a registration signal is received from the transmitter 33, the transmitter ID is registered. Make it possible. When the user operates the registration switch 33d of the transmitter 33 for the first transmitter, the transmitter 33 is a signal including its own transmitter ID and an identifier indicating that the signal is a registration signal. Send a signal containing Then, when the receiver 34 receiving this signal confirms that the identifier is included in the signal, the receiver 34 fully registers the transmitter ID included in the signal in the storage unit 34h and A signal including the receiver ID of is transmitted. And the transmitter 33 which received this signal carries out the main registration of the receiver ID contained in the said signal in the memory | storage part 33h. According to such processing, since the operation on the receiver 34 can be omitted, the effect is particularly great when the trouble and risk for operating the registration switch 34d are likely to increase like a large shutter. Further, since the registration switch 34d of the receiver 34 can be omitted, the configuration of the receiver 34 can be further simplified.

  However, when such a process is performed, when a registration signal is transmitted from a radio wave communication system of another shutter device installed in the vicinity, the transmitter ID and the receiver ID are set. There is a possibility that it will be registered incorrectly. Therefore, it is more preferable to take measures to reduce this possibility. As such a device, for example, in the receiver 34 that has received the registration signal from the transmitter 33, the received strength (RSSI: Received Signal Strength Indicator) of the signal is measured, and the received strength is not less than a predetermined value. Only when the signal is transmitted from the transmitter 33 installed in the same shutter device 10 to which the receiver 34 is set, the transmitter ID included in the signal is included. Is registered in the storage unit 34h, and a signal including its own receiver ID is transmitted. Similarly, in the transmitter 33 that has received the signal from the receiver 34, the receiver ID included in the signal is fully registered in the storage unit 33h only when the reception intensity of the signal is equal to or higher than a predetermined value. You may do it.

(Registration process-Modification 5)
Alternatively, the transmitter 33 and the receiver 34 may alternately transmit their own IDs twice each. That is, when the user operates the registration switch 33d of the transmitter 33 for the first transmitter, the transmitter 33 transmits a signal including its own transmitter ID. Receiving this signal, the receiver 34 temporarily registers the transmitter ID included in the signal in the storage unit 34h and transmits a signal including its own receiver ID. The transmitter 33 that has received this signal temporarily registers the receiver ID included in the signal in the storage unit 33h and transmits the signal including its own transmitter ID again. Since the receiver 34 that has received this signal has continuously received the transmitter ID included in the signal for the same number of receptions, the receiver 34 registers the transmitter ID in the storage unit 34h, and at the same time receives its own receiver ID. The signal including is transmitted again. The transmitter 33 that has received this signal has received the receiver ID included in the signal continuously for the same number of receptions, and thus registers the receiver ID in the storage unit 33h.

(About predetermined processing)
In the above embodiment, the receiver 34 performs a predetermined process related to registering the transmitter ID in the storage unit 34h only when the operation mode of the receiver 34 is switched to the second registration mode. In this embodiment, the “predetermined process relating to registering the transmitter ID in the storage unit 34h” has been described as meaning the process of registering the transmitter ID in SA11. However, as the “predetermined process relating to registering the transmitter ID in the storage unit 34h”, various other processes can be included. For example, the same transmitter ID is continuously received the same number of times. Or a process for temporarily registering a transmitter ID can be included.

  The transmitter 33 is described as performing a predetermined process related to registering the receiver ID in the storage unit 33h only when the operation mode of the transmitter 33 is switched to the first registration mode. In the present embodiment, the “predetermined process relating to registering the receiver ID in the storage unit 33h” has been described as meaning the process of registering the receiver ID in SB6. However, the “predetermined process relating to registering the receiver ID in the storage unit 33h” can include various other processes. For example, the same receiver ID is continuously received the same number of times. Or a process for temporarily registering the receiver ID can be included.

(About operation mode)
In the above embodiment, only when the operation mode of the transmitter 33 is switched to the first registration mode, the receiver ID can be fully registered in the transmitter 33, and the receiver 34 Only when the operation mode is switched to the second registration mode, the transmitter ID can be fully registered in the receiver 34. However, the operation mode may be switched to the registration mode only in one of the transmitter 33 and the receiver 34.

  For example, in the case where the registration operation is performed mainly by the user performing a registration operation on the transmitter 33, the operation mode of the transmitter 33 is changed to the first operation mode by performing the registration operation on the transmitter 33. By switching to the registration mode, the receiver ID can be fully registered in the transmitter 33. On the other hand, for the receiver 34, the receiver does not switch to the second registration mode. It may be possible to register the transmitter ID in 34. Or, conversely, in the case where the registration operation is performed mainly by the user performing a registration operation on the transmitter 33, the operation mode of the receiver 34 is switched to the second registration mode, so that the transmission is performed to the receiver 34. The machine ID can be fully registered, while the transmitter 33 can be fully registered with the transmitter 33 without switching its operation mode to the first registration mode. Also good.

  Alternatively, when the registration operation is performed mainly by the user performing a registration operation on the receiver 34, the operation mode of the receiver 34 is changed to the second operation mode by performing the registration operation on the receiver 34. By switching to the registration mode, it is possible to perform main registration of the transmitter ID in the receiver 34. On the other hand, for the transmitter 33, the transmitter does not switch to the first registration mode. It may be possible to register the receiver ID in 33. Or, conversely, in the case where the registration work is performed mainly by the user performing a registration operation on the receiver 34, the operation mode of the transmitter 33 is switched to the first registration mode, so that the transmitter 33 receives the registration operation. On the other hand, the receiver ID can be fully registered on the receiver 34 without switching the operation mode to the second registration mode. Also good.

  In addition, after switching the operation mode of the receiver 34 from the second normal mode to the second registration mode, conditions for returning to the second normal mode can be arbitrarily determined. For example, after the transmitter 33 fully registers the receiver ID in SB6 of FIG. 5, the transmitter 33 transmits a first confirmation signal indicating the end of registration, and the receiver 34 receives the first confirmation signal. When receiving, the receiver 34 may return its own operation mode to the second normal mode.

  Similarly, the conditions for returning to the first normal mode after switching the operation mode of the transmitter 33 from the first normal mode to the first registration mode can be arbitrarily determined. For example, as described above, after the receiver 34 receives the first confirmation signal and returns its operation mode to the second normal mode, the receiver 34 transmits a second confirmation signal indicating that the registration is completed. Then, when the transmitter 33 receives the second confirmation signal, the transmitter 33 may return its own operation mode to the first normal mode.

(About processing to reduce the possibility of incorrect registration)
In the above embodiment, after the transmitter 33 switches its operation mode to the first registration mode in SB3 of FIG. 4, it transmits from the radio wave wireless communication system of another shutter device installed in the vicinity. When a signal including the received receiver ID is received, the receiver ID may be registered in SB6 of FIG. 5, and there is a possibility of erroneous registration. Therefore, processing for reducing the possibility of such erroneous registration may be performed, and processing for this purpose will be exemplified below. These processes may be combined with each other.

  For example, in the above embodiment, the signal including the transmitter ID in SB4 in FIG. 4 is transmitted a predetermined number of times (for example, twice), so that the receiver 34 transmits the signal including the receiver ID. In the device 33, the receiver ID is registered in SB6 of FIG. 5 only for the receiver ID received after transmitting the signal including its own transmitter ID a predetermined number of times (for example, twice). You may do it.

  Alternatively, since the receiver 34 transmits the signal including the receiver ID after the main registration of the transmitter ID in SA11 in FIG. 5 is performed, the receiver 34 transmits the signal including the receiver ID. In this case, the transmitter ID that has performed the main registration is included in the signal. The transmitter 33 may register the receiver ID included in the signal only when the signal including the transmitter ID matching the transmitter ID of the transmitter 33 is received.

  Alternatively, in SB3 of FIG. 4, after the transmitter 33 switches its own operation mode to the first registration mode, only the receiver ID included in the signal received within a predetermined time may be registered.

  Alternatively, the receiver 34 continuously transmits a signal including the receiver ID a predetermined number of times (for example, twice), and the transmitter 33 continuously receives the signal including the same receiver ID the predetermined number of times. Only in this case, only the receiver ID may be registered.

(Replacement and combination of embodiment and modification)
About embodiment and the modification which were demonstrated so far, you may substitute or combine all or one part between each other. For example, you may combine the modification about the operation mode mentioned above, and the modification about the process which reduces the possibility of the erroneous registration mentioned above in the embodiment mentioned above.
