Description

  The present invention relates to an opening / closing system, for example, a system that controls the operation of a shutter, a door, a window, an overhead door, a gate, a gate (a gate such as a parking lot), a roll screen (for example, a light shielding curtain), a blind, an awning device, and the like. It can be applied to.

  The present invention also relates to an opening / closing device as a component of such an opening / closing system.

  As a composite shutter system composed of two shutter devices A and B, each of which can operate independently, for example, when one shutter device is open in order to block the inside of the factory from the outside air, Some have an interlock function that restricts the opening of the shutter device.

  In this composite shutter system having an interlock function, when one shutter device A is in the open state, the other shutter device B can only be kept in the closed state, so that the two shutter devices A and B are both in the closed state. At some point, the shutter operation has the highest degree of freedom, and both the shutter devices A and B can perform the opening operation according to the received shutter operation designation signal.

  However, if the two shutter devices A and B are opened simultaneously, the inside of the factory cannot be shut off from the outside air. Therefore, the outside air shut-off state is maintained by the following simple one-way communication. ing.

  That is, when one of the two shutter devices A and B in the closed state (here, A) performs an opening operation, a predetermined opening operation notification signal is sent to the other shutter device (here Then, the occurrence of the opening operation is notified by transmitting to B). In the other shutter device B that has received the opening operation notification signal, even if it receives a shutter operation designation signal for instructing itself to open, the shutter device B is not obeyed and maintains the closed state. Can do.

The technique described in Patent Document 1 below also relates to a composite shutter system having such an interlock function. In the technology of Patent Document 1, different priorities are given to a plurality of shutter devices (corresponding to A and B) in a composite shutter system, and control based on the priorities is performed, so that a plurality of shutter devices are controlled. Thus, when the opening operation is instructed almost simultaneously and the opening operation notification signal is transmitted almost simultaneously, the contradiction that prevents the plurality of shutter devices from performing the opening operation together is resolved.
JP2003-64945

  By the way, when the user tries to pass through the space (buffer space) sandwiched between the two shutter devices A and B described above, the first shutter device (here, A) is opened. (At this time, the second shutter device B is in the closed state), after the user enters the buffer space, the first shutter device A performs the closing operation, and then 2 After the first shutter device B is opened, the user passes through the buffer space. Further, after passing through, the second shutter device B is caused to perform a closing operation as necessary.

  However, in order to cause each of the shutter devices A and B to perform such an operation, a portable remote control transmitter capable of effectively transmitting a shutter operation designation signal to the shutter devices A and B is provided. It is necessary to always carry it, or to provide a fixed operation section (corresponding to a fixed remote control transmitter) capable of transmitting a shutter operation designation signal in the buffer space. This is because if there is no fixed operation part in the buffer space, there arises a disadvantage that the opening operation cannot be instructed to the second shutter device B described above.

  However, it is inconvenient for the user to always carry the portable remote control transmitter and operate it frequently.

  Furthermore, even if the fixed operation unit is provided in the buffer space, an operation burden for the user to operate the fixed operation unit is generated, and the components constituting the composite shutter system are equivalent to the fixed operation unit. There are disadvantages such as an increase in the number.

  Instead of a portable remote control transmitter or a fixed operation unit, a remote control transmitter with a sensor that automatically transmits the shutter operation designation signal to the shutter device A or B when a predetermined sensor detects a user. Are installed at appropriate positions such as in front of the shutter device A and in front of the shutter device B, and when the sensor detects that the user has moved to the installation position, the shutter device automatically opens. However, even in such a case, there is a problem that the number of components increases due to the installation of the remote control transmitter with the sensor in the buffer space.

  The above-mentioned problems are common not only to shutters such as sheet shutters, garage shutters, and window shutters, but also to other opening / closing systems and opening / closing devices such as doors, windows, and overhead doors.

  An object of the present invention is to provide a convenient and efficient switching system and switching device.

(A) Embodiment Hereinafter, an embodiment will be described with reference to an example in which the opening / closing system and the opening / closing device according to the present invention are applied to a composite shutter system (remote operation system (remote control system)) having two shutters.

  In general, the remote control system includes a wired remote control system, the wireless remote control system, and a mixed system in which these are mixed.

  Here, the wired remote control system is a remote control system including a shutter system as a component, and performs a shutter operation by wired communication. The wireless remote control system is a remote control system including a shutter system as a component. Thus, the shutter operation is performed by wireless communication.

  In general, the wireless remote control system is advantageous in that the shutter operation can be performed from an unspecified position that is far away, and it is easy to use. The communication operation is reliable and the shutter operation is always specified at a specific position. If you want to do that, a wired remote control system is for you.

Also, if the same shutter system can be controlled by wire or wireless, it is flexible and either method can be taken for the convenience of the user. Therefore, the actual remote control system is often a mixed system in which the features of these wireless remote control system and wired remote control system are mixed.
However, in the present embodiment, for the sake of brevity, the composite shutter system includes a separate remote control receiver that can direct the shutter operation using different remote control transmitters (or remote control transmitters with sensors). It is assumed that the wireless remote control system is provided.

  For communication between the remote control receiver and the remote control receiver, it is possible to use wired communication, wireless communication, a mixture of wired communication and wireless communication, etc., but in this embodiment, wired communication is used. Shall.

(A-1) Configuration of Embodiment FIG. 2 shows an example of the overall configuration of the composite shutter system 10 of the present embodiment.

  In FIG. 2, the composite shutter system 10 includes remote control receivers 11A and 11B, remote control transmitters 12A and 12B, shutter devices 14A and 14B, a buffer space 13, a transmission path 15, and a remote control transmitter with a sensor. 16A (, 16B).

  Of these, the buffer space 13 corresponds to the above-described buffer space, and is a buffer space that can be covered with a wall surface, a floor surface, and the shutter curtains of the two shutter devices 14A and 14B. In the illustrated example, the shape of the buffer space 13 is a rectangular parallelepiped, but this need not be limited to a rectangular parallelepiped. For example, since it is bent in an “L” shape, it is possible that the other cannot be seen from one side (for example, the shutter curtain of the shutter 14B on the user U2 side cannot be seen from the user U1 side).

  There may be various purposes for providing such a buffer space 13. For example, the buffer space 13 may be used to block the outside air and achieve the purposes such as dust prevention, insect protection, cold insulation, and heat insulation. If the SA side where the user U1 is located is the inside (such as a factory), the SB side where the user U2 is located is the outside (such as a factory). When the required precision such as dust prevention, insect prevention, cold insulation, and heat insulation is high, a shutter or a door with high airtightness can be used instead of the shutter devices 14A and 14B.

  For example, as shown in FIG. 5, another composite shutter system (referred to as 9) that is the same as the composite shutter system 10 is arranged inside the same building such as the factory 8, and By transporting along the route RT1 indicated by the alternate long and short dash line, it is also possible to efficiently transport the processed material and the result of processing performed inside the factory 8 using the processed material. In this case, when seeing each of the composite shutter systems 10 and 9, one-way conveyance is performed. That is, for the composite shutter system 9, one-way conveyance from the outside to the inside of the factory 8 (processing material conveyance (carrying-in)) is performed, and for the composite shutter system 10, one from the inside to the outside of the factory 8. Transportation (transportation (unloading) of the processed product) is performed.

  In the composite shutter system 10 that can be used in such a form, the shutter devices 14A and 14B shown in FIG. 2 can be a slat shutter including a large number of slats made of metal such as iron. It may be a sheet shutter device mainly composed of a sheet-like curtain portion made of a light material such as polyester. Since the material of the sheet shutter is lightweight, the moment of inertia that can act on the output shaft of a motor (not shown) that supplies torque that serves as a power source for the opening / closing operation of the shutter devices 14A and 14B is small, and the opening / closing operation is fast. Can be easily realized. As an example, the motor may be an AC servo motor, for example, and may rotate at a speed of about 3000 rotations per second when the shutter device 14A performs an opening operation (or a closing operation).

  The two shutter devices 14A and 14B arranged at both ends of the buffer space 13 include a motor and the like in addition to the illustrated shutter curtain, and perform a shutter curtain opening / closing operation according to the rotation of the output shaft of the motor. It is.

  The rotation of the output shaft of the motor is controlled by a shutter control unit 64 (see FIG. 1) provided in the remote control receivers 11A and 11B.

  The user U1 who performs an opening / closing operation of the shutter device 14A or the like can also perform a desired shutter operation by operating the portable remote control transmitter 12A. This operation includes a closing operation for moving the shutter lower end portion 14AD in the direction of arrow D1, an opening operation for moving the shutter lower end portion 14AD in the direction of arrow D2, and a stopping operation for stopping the moving lower end portion 14AD at that position. The relationship between the user U2 and the remote control transmitter 12B and the shutter device 14B is the same as this.

  However, the remote control transmitter capable of instructing the shutter operation to the shutter device 14A is not limited to the remote control transmitter 12A, and a plurality of remote control transmitters may be used as necessary. The same applies to the shutter device 14B and the remote control transmitter 12B.

Except for special remote control transmitters (setting remote control transmitters), general remote control transmitters (normal remote control transmitters) often correspond to themselves (by themselves registering IDs described later). The shutter operation can be instructed to only one shutter device. Therefore, there is no difference between a setting remote control transmitter as a device and a normal remote control transmitter.

  In the following description, it is assumed that the remote control transmitters 12A and 12B are the normal remote control transmitters.

  The remote control transmitter 12A has an appearance as shown in FIG. 3, for example. The appearance and size of the remote control transmitter 12B may be the same as in FIG.

  The remote control transmitter 12A is a palm-sized transmitter that is portable and compact enough to fit in the palm of the user U1. Thus, in order to accommodate all functions in the compact main body 12AD, it is necessary to save the functions of the remote control transmitter 12A to the limit.

  In FIG. 3, the main body 12AD of the remote control transmitter 12A includes three operation switches 51 to 53 of a PBS (push button switch) type projecting from the upper surface thereof. These operation switches 51 to 53 are shutter operation switches that can perform a desired shutter operation.

  In the present embodiment, among the shutter operation switches 51 to 53, the shutter operation switch 51 is an opening operation switch for causing the shutter 14A to open, and the shutter operation switch 52 is for causing the shutter 14A to close. The shutter operation switch 53 is a stop switch for stopping the opening or closing operation of the shutter 14A at an arbitrary timing.

  However, it is also possible to instruct various shutter operations and the like by changing the combination of the operation switches to be pressed or changing the way to press them. As an example, the close function switch 52 and the stop switch 53 may be simultaneously pressed shortly (for example, within 2 seconds) to enable the interlock function to be instructed or invalidated. Actually, since it is difficult for the user U1 to press at exactly the same time, the stop switch 53 is first pressed, and the closing switch 52 is pressed while the stop switch 53 is being pressed. This is because, when the closing operation switch 52 is pressed first, the shutter 12A starts the closing operation.

  An example of the internal configuration of the remote control transmitter 12A is shown in FIG. The internal configuration of another remote control transmitter 12B may be the same as this.

  However, the remote control transmitters 12A and 12B are not necessarily products of the same manufacturer. The functions of the remote control transmitter 12A and the remote control receiver 11A correspond to each other and must basically be products of the same manufacturer. Similarly, the functions of the remote control transmitter 12B and the remote control receiver 11B also correspond to the basics. If the remote control transmitters 12A and 12B are products of different manufacturers, the remote control receivers 11A and 11B are also products of different manufacturers. It is normal.

  In this way, when the remote control receivers 11A and 11B are products of different manufacturers, the other opening operation instruction signal NT12 and the response signal NT22 (to be described later) characteristic of this embodiment are normally transmitted and received. Standardization may be necessary.

(A-1-1) Internal Configuration of Remote Control Transmitter In FIG. 4, the remote control transmitter 12A includes an ID storage unit 50, a radio transmission unit 54, a transmission processing unit 55, a processor 56, and a procedure storage unit 57. The operation detection unit 58 and the operation response unit 59 are provided, and the operation switches 51 to 53 are provided in the operation detection unit 58.

  Among these, the wireless transmission unit 54 is a part of the remote control receiver 11A facing a wireless reception unit 61 (to be described later) through a space as a wireless transmission path, and a transmission signal received from the transmission processing unit 55 via a predetermined signal line. A wireless signal WL1 corresponding to WS is wirelessly transmitted. For this purpose, the wireless transmission unit 54 includes a transmission antenna system, a filter circuit, and the like. The wireless signal WL1 may be a weak radio wave having a frequency band of, for example, about 300 MHz or 400 MHz and a transmission power of, for example, about 1 mW.

  The transmission processing unit 55 has a function of executing necessary processing such as encoding processing and modulation processing, and changes the content of the transmission signal WS to be generated according to the transmission processing signal RP supplied from the processor 56. .

  In the case of the remote control transmitter 12A, the content of the transmission signal WS is, for example, a finite number determined according to the type of shutter operation to be specified, ID registration operation, and the like. The source may be, for example, a ROM (read-only memory), etc.) is also present in the transmission processing unit 55, and selects and reads one transmission information from the generation source in accordance with the transmission processing signal RP. It may be a configuration.

  Here, the ID is a remote control transmitter (for example, the use frequency of the remote control transmitter 12B is the same as 12A, and the remote control receiver 11A may be confused with the remote control receiver 11A because the frequency band to be used is the same. If the distance between the receivers 11A and 11B is not sufficiently long, the remote control transmitter 12B can be uniquely identified), and can truly be wirelessly transmitted to the remote control receiver 11A. This is an identifier used for operating the shutter 14A based on only the wireless signal WL1 transmitted from the user's remote control transmitter. For this reason, the remote control transmitter 12A requires a certification mechanism (not shown) that accommodates the ID in the radio signal WL1 every time wireless transmission is performed. The remote control receiver 11A identifies the ID and performs user authentication. A verification mechanism (not shown) for performing (or terminal authentication) is required.

  In the case of a sheet shutter, it is often placed on the wall that separates one room from another in a building such as a factory, and it is mechanically weak compared to slat shutters, so it originally has security functions. Considering the weak point, in the environment where there is no other remote control transmitter (for example, 12B) within the reception range of the remote control receiver 11A and the shutter operation as intended by the user U1 can be performed, the proof mechanism Even if the verification mechanism is omitted, there is little trouble.

  However, in this embodiment, a proof function and a verification function are provided. The ID storage unit 50 forms part of the proof function, and the ID registration unit 77 (see FIG. 1) on the remote control receiver side forms part of the verification function.

  The ID storage unit 50 is a part that stores the ID value (here, ID1) assigned to the remote control transmitter 12A. The ID is stored in the ID storage unit 50, for example, in the manufacturing process of the remote control transmitter. Since the ID assigned to the remote control transmitter and stored in the ID storage unit 50 is not permanently changed once stored due to its nature, the ID storage unit 50 may be configured by a ROM or the like. it can.

  If the remote control transmitter 12A is the above-described setting remote control transmitter, for example, a special value that is always ID-registered in all remote control receivers (for example, 11A and 11B) is used as the ID1. It may be. In consideration of security and the like, when the existence of such a special value ID is not allowed, ID1 itself is a normal identifier, and ID1 is used as the ID registration unit 77 of the remote control receiver 11A and the remote control receiver. By registering in both ID registration sections of 11B, the remote control transmitter 12A can be used as the setting remote control transmitter.

  However, even if it is a setting remote control transmitter, the transmission power of the remote control transmitter 12A is weak, so the distance (wireless reach distance) that the radio signal WL1 effectively reaches (the radio reach distance. Is equal to, for example, several tens of meters, and is even shorter depending on various conditions such as the surrounding radio wave environment. Therefore, the wireless signal WL1 transmitted from the remote control transmitter 12A reaches the remote control receiver (for example, 11B) located on the opposite side of the buffer space 13, and the shutter operation according to the content of the wireless signal WL1 is performed by the shutter device 14B. In order to execute, the distance to the remote control receiver 11B needs to be within the wireless reachable distance. If the distance to the remote control receiver 11B is longer than the wireless reachable distance, the user U1 carrying the remote control transmitter 12A moves and the distance is not within the wireless reachable distance, so that the quality sufficient to establish communication. Because the wireless signal WL1 cannot be delivered, the remote control receiver 11B cannot execute the shutter operation.

  The processor 56 that outputs the transmission processing signal RP to the transmission processing unit 55 is a CPU (central processing unit) of the remote control transmitter 12A.

  The operation detection unit 58 provided with the three operation switches 51 to 53 described above, which is the only remote operation means for the user U1 who operates the remote control transmitter 12A whose function is saved to the limit, This is a portion that outputs the operation detection signals PB1 and PB2 when the pressing stroke reaches a predetermined length. The operation detection signal PB1 takes different states depending on the operation switch that has detected the depression, and the operation procedure is temporarily stored in the procedure storage unit 57.

  The procedure storage unit 57 is a part that determines what kind of operation or input data is specified in the temporarily stored procedure and supplies a determination signal DS as a determination result to the processor 56.

  Similarly to the PB1, the operation detection signal PB2 supplied to the operation response unit 59 at the same time as the operation detection signal PB1 is supplied to the procedure storage unit 57 is in a different state depending on the operation switch that has detected the depression. However, in the present embodiment, the operation switches 51 to 53 are not distinguished from each other and assume the same state.

  The operation response unit 59 that has received the operation detection signal PB2 is a sound generator such as a buzzer, and outputs a response output RA to notify the user U1 that the depression of the operation switches 51 to 53 has been detected effectively. Part. In the present embodiment, since the operation switches 51 to 53 are not distinguished, when any one of the operation switches is sufficiently depressed, a buzzer sound having a constant pitch and a constant tone color is heard by the user U1 as the response output RA. Thereby, the user U1 can aurally confirm the effectiveness of the switch operation.

  For example, when operating a keyboard with a personal computer or the like, in an environment having a much larger and richer user interface than the remote control transmitter 12A, whether or not a key press is recognized by the machine is a bit. Although it can be easily confirmed by visually observing a screen display such as a map display or the like, the remote control transmitter 12A that requires high portability is cut off to the limit from the viewpoint of saving the functions described above. It is important how to confirm whether or not the user's operation is efficiently recognized by the machine (here, the remote control transmitter 12A) with a small configuration.

  Here, the response output RA of the operation response unit 59 is set to a constant pitch and a constant tone buzzer sound. However, if necessary, the pitch is set according to the depressed operation switches 51 to 53 or a combination of simultaneously depressed operation switches. You may make it change a tone or a tone. Further, not only the auditory means by the sound generator but also a light emitting element such as an LED (light emitting diode) is used to inform the user U1 that the operation of the operation switch has been detected effectively by visual means. Alternatively, visual means and auditory means may be used in combination.

  In the state of FIG. 2, the shutter operation system 10A including the shutter device 14A located on the user U1 side, the remote control receiver 11A, and the remote control transmitter 11A, the shutter device 14B located on the user U2 side, the remote control receiver 11B, and the remote control Since the shutter operation system 10B composed of the transmitter 11B is originally a separate system, the shutter device 14A basically performs the shutter operation as instructed by the user U1 using the remote control transmitter 11A. The shutter device 14B performs the shutter operation as instructed by the user U2 using the remote control transmitter 11B.

  However, in the case of the present embodiment, the purpose is to block the outside air using the buffer space 13, and therefore it is necessary to prohibit the shutter devices 14A and 14B from opening simultaneously.

  This prohibition is performed based on the communication of the self-operation notification signal NT11 and the other operation notification signal NT21 performed between the remote control receivers 11A and 11B. These two operation notification signals NT11 and NT21 are basic signals for realizing the interlock function.

  The remote control receiver 11A (, 11B) is also preferred to save functions as much as possible from the viewpoint of compactness and cost reduction. However, unlike the remote control transmitter 12A, the remote control receiver 11A (11B) is normally fixedly arranged. The level of demand for savings is not so strict. Therefore, the saving of the functions of the remote control receivers 11A and 11B is rather required from a cost standpoint. For example, it is advantageous not to install a bi-directional communication function (negotiation function) between the remote control receivers 11A and 11B that causes an increase in necessary processing capacity.

  The user U1 carrying the remote control transmitter 12A can perform a desired shutter operation by pressing the operation switches 51 to 53 when instructing an opening / closing operation or the like of the shutter device 14A. In the case of using in the form shown in FIG. 5, it is often more convenient to use the remote controller transmitter with sensor 16A instead of the remote controller transmitter 12A. For example, in a factory or the like, there are many users who need to pass through the two shutters 14A and 14B. However, if a remote control transmitter (corresponding to 12A) is carried by each of these many users, a necessary remote controller is required. Although the number of transmitters increases, the need for the remote controller transmitter with sensor 16A is eliminated. When using the remote control transmitter with sensor 16A, as will be described later, it is not necessary to operate the operation switch 51 of the remote control transmitter 12A in the vicinity of the shutter device 14A.

  The remote controller transmitter with sensor 16A is substantially the same as the remote controller transmitter 12A when viewed from the remote controller receiver 11A, and the internal structure of the device is almost the same as the remote controller transmitter 16A.

  However, a point that a sensor for detecting the user U1 and the like is mounted and a point that the wireless signal WL1 is automatically transmitted when the sensor detects the user U1 and the like (therefore, the operation switches 51 to 53 are The only difference is that the remote control transmitter 16A is not. Here, when the sensor detects the user U1, the wireless signal WL1 transmitted by the remote control transmitter with the sensor instructs the shutter opening operation.

  The remote control transmitter 12A requires portability, whereas the sensor-equipped remote control transmitter 16A does not require portability. Therefore, a wired transmission path is provided between the sensor-equipped remote control transmitter 16A and the remote control receiver 11A. Can be connected with. Therefore, it is possible to instruct the opening operation of the shutter not by wireless communication (wireless signal WL1) but by wired communication through the wired transmission path (not shown). In general, wired communication is less susceptible to noise from the surrounding environment than wireless communication, and the frequency of occurrence of transmission errors is low, so communication reliability is high.

  The sensor for the remote control transmitter with sensor 16A can detect that the user U1 (or the processed material transported through the factory 8 or the processed result) has moved to that position. Any optical sensor that uses light can be used as an example. In the case of an optical sensor, for example, a transmissive optical sensor that detects that the light OP1 emitted from a light irradiator (not shown) is blocked by the user U1 or a processing material, or light emitted from the light irradiator. It is possible to use a reflection type optical sensor that detects that the light is reflected upon hitting the user U1 or the processing material.

  Using such sensor-equipped remote control transmitters 16A and 16B, the user U1 or the like simply moves to the front of the sensor-equipped remote control transmitter (for example, 16A), and the shutter (for example, 14A) is automatically opened. Done. However, since the above-described interlock function prohibits the two shutters 14A and 14B from being opened simultaneously, in order for the user U1 or the like to pass through the buffer space 13 along the passing direction PD1, for example, the opening operation is once performed. A mechanism for closing the shutter (for example, 14A) is necessary.

  As the mechanism, for example, a remote control transmitter with a sensor similar to 16A and 16B is arranged at positions FA and FB shown in FIG. 2, and when this remote control transmitter with sensor detects the user U1 or the like, the shutter device It is also conceivable to configure (for example, 14A) to perform a closing operation. However, when processing the processing material at the factory 8 or the like, the processing material or result is obtained both when the processing material is carried into the factory 8 and when the processing result is carried out from the factory 8. Since an object moves at a substantially constant speed, it is convenient to adopt a mechanism in which an opened shutter (for example, 14A) repeats an operation of automatically closing in a certain time.

  In the case of this mechanism, if one-way along the passing direction PD1 is assumed, only the remote control transmitter with sensor 16A is required, and the remote control transmitter with sensor at positions FA and FB, or the remote control transmitter with sensor 16B is installed. This is advantageous because it can be omitted.

  The composite shutter system 10 according to the present embodiment employs a mechanism that repeats an operation in which an opened shutter (for example, 14A) automatically closes in a certain time as described above. In order to reduce the number of devices constituting the composite shutter system 10 as much as possible, the other opening operation instruction signal NT12 (and the response signal NT22) is communicated between the remote control receivers 11A and 11B. The other opening operation instruction signal NT12 is a signal for instructing another remote control receiver (11B when viewed from 11A) to perform the opening operation.

  An example of the internal configuration of the remote control receiver 11A is as shown in FIG. The internal configuration example of the remote control receiver 11B may be basically the same as that in FIG. 1, but here, the description will proceed assuming that the remote control receiver 11A is mainly shown in FIG. If this remote control receiver 11A is its own remote control receiver, the remote control receiver 11B facing the remote control receiver 11A via the transmission line 15 is another remote control receiver.

  However, if the user U1 or the like does not pass through the buffer space 13 along the passing direction PD1 and does not pass along the opposite direction PD2, it is assumed that the remote control receivers 11A and 11B of the other remote control receivers 11A and 11B are assumed. There are differences in roles.

  That is, the remote control receiver 14A disposed on the side of the shutter device 14A through which the user U1 or the like passes first performs a closing operation after the shutter device 14A is opened and fully opened, and is in a fully closed state. Then, the other opening operation instruction signal NT12 is transmitted. On the other hand, the other remote control receiver 14B disposed on the side of the shutter device 14B through which the user U1 and the like later passes, according to the other opening operation instruction signal NT12 received via the transmission path 15, the shutter device 14A. Is opened, performs a closing operation after the fully opened state, and transmits the response signal NT22 when the fully closed state is reached. When this remote control receiver 11A receives this response signal NT22, one unit operation consisting of a series of operations ends normally.

  Assuming that the shutter 14A and 14B are both fully closed as an initial state, the shutter 14A opens (OP11) and then closes (OP12) (then, another opening operation instruction signal NT12 is transmitted). The unit operation is from the opening operation (OP21) of the shutter 14B to the closing operation (OP22) (the response signal NT22 is transmitted after the closing operation) (in response to this NT12).

  The timing at which the other remote control receiver 11B on the shutter device 14B side transmits the response signal NT22 may be before the closing operation, not after the closing operation OP22 of the shutter 14B. For example, when the shutter 14B performs an opening operation to a predetermined height (effective opening operation position) in response to the other opening operation instruction signal NT12 (this effective opening operation position is sufficient for the user U1 or the like to pass through). The response signal NT22 may be transmitted to the shutter position corresponding to the opening of the height opening. Here, the time after the closing operation OP22 of the shutter 14B is referred to as the first transmission timing, and when the shutter 14B performs the opening operation to the effective opening operation position in response to the other opening operation instruction signal NT12 (this timing is the opening timing). The operation OP21 may be in the middle) and is referred to as a second transmission timing.

  The meaning of the response signal NT22 varies depending on whether transmission is performed at the first or second transmission timing.

  The response signal NT22 transmitted at the first transmission timing has a meaning of informing the remote controller receiver 11A that one unit operation is completed and a new unit operation can be started. This also informs that the shutter 14B is once opened on the other remote control receiver 11B side, so that it is highly likely that the user U1 or the like no longer exists in the buffer space 13. It also has a meaning to convey to the remote control receiver 11A.

  On the other hand, the response signal NT22 transmitted at the second transmission timing is opened with an opening high enough for the user U1 and the like to pass through, and the user U1 and the like can exit the buffer space 13. It is meaningful to notify the remote control receiver 11A that this has happened.

  Note that the remote control receiver 11B is informed of the start of the opening operation by the other operation notification signal NT21 to the remote control receiver 11A. However, the height of the opening that is opened by the opening operation can be determined by the user U1 or the like. Therefore, there is an advantage that the response signal NT22 is transmitted at the second transmission timing.

  There are various specific examples of the effective opening operation position. As an example, a position having a height of about 1 meter may be set as the effective opening operation position. If this height of 1 meter is stored in the form of the number of encoder pulses supplied from the motor, the processor 63 counts the number of encoder pulses supplied from the motor and stores the count result. By comparing with the number of pulses, it can be recognized that the effective opening position has been reached.

  As is clear from the above description, the opening operation OP21 of the shutter 14B performed by the other remote control receiver 11B is performed in response to the received other opening operation instruction signal NT12. The sensor-equipped remote control transmitter 16B can be omitted. Further, since the closing operations OP12 and OP22 of the shutters 14A and 14B are automatically performed by the remote control receivers 11A and 11B, it is not necessary to arrange a remote control transmitter with a sensor at the positions FA and FB.

(A-1-2) Internal Configuration of Remote Control Receiver In FIG. 1, the remote control receiver 11A includes a radio reception unit 61, a reception processing unit 62, a processor 63, a shutter control unit 64, and an input unit 65. , Output unit 66, effective opening operation flag 67, self-operation information flag 68, instruction information flag 69, other operation information flag 70, fully closed state determination unit 71, response transmission unit 72, response reception determination Unit 73, counter display unit 74, setting storage unit 75, setting processing unit 76, and ID registration unit 77.

  Among these, the wireless receiving unit 61 includes a receiving antenna system, a filter circuit, and the like, and has received a wireless signal WL1 transmitted from the remote control transmitter 12A via a space (the wireless transmission path). A reception signal WS corresponding to the radio signal is output. The reception signal WS that is a signal corresponding to the transmission signal WS is supplied to the reception processing unit 52 via a predetermined signal line.

  The reception processing unit 52 is a part that performs necessary processing such as demodulation processing and decoding processing on the received reception signal WS to generate and output a reception processing signal RP.

  The reception processing signal RP is a signal corresponding to the transmission processing signal RP, and can function as a shutter operation designation signal for designating a shutter operation such as a shutter opening operation, a closing operation, or a stop operation. It also functions as a signal for instructing registration of an ID assigned to the remote control transmitter 12A when shipped from a factory where the remote control transmitter is manufactured or assembled.

  The shutter control unit 64 supplies a shutter control signal CC corresponding to the opening / closing control signal CS received from the processor 63 to the motor, and receives a shutter operation desired by the user (for example, U1) and receives the remote control from the remote control transmitter with sensor 16A. This is a part that realizes a shutter operation according to a signal supplied to the machine 11A. The shutter control unit 64 may be provided outside the remote control receiver 11A instead of as a part of the remote control receiver 11A as necessary.

  The processor 63 that receives the reception processing signal RP from the reception processing unit 62 is a part that functions as the CPU of the remote control receiver 11A. Further, the processor 63 also has a function of receiving the other operation notification signal NT21 or the response signal NT22 transmitted from the other remote control receiver 11B opposed to the input unit 65 via the transmission line 15 as the signal N2.

  As a result, the processor 63 can perform an operation according to the reception processing signal RP, the other operation notification signal NT21, and the response signal NT22.

  The input unit 65 that supplies the signal N2 to the processor 63 of the own remote control receiver 11A is connected to the output unit (component corresponding to the output unit 66 of FIG. 1) of the other remote control receiver 11B via the transmission line 15. Has been. Although a wireless transmission path can be used as the transmission path 15, a wired transmission path is used here.

  Specifically, the wired transmission line 15 can be configured using, for example, a twisted pair cable (twisted pair) or a coaxial cable. The same signal line may be used for the signal transmission in the direction from the remote control receiver 11A to the remote control receiver 11B and the signal transmission in the direction from the remote control receiver 11B to the remote control receiver 11A. However, in this embodiment, a separate signal line is used in order to reduce the frequency of deterioration of communication quality due to the collision between the signal NT21 or NT22 transmitted in each direction and the signal NT11 or NT12.

  However, even if only the signal line in the transmission line 15 is separated, if there is only one resource in each remote control receiver 11A, 11B, such as the processor 63, inside each remote control receiver, Again, collisions can occur. For example, a resource such as the processor 63 can execute only one process at a time. For example, when the other operation notification signal NT21 is received while the processing for transmitting the self-operation notification signal NT11 is being executed, the processing for both signals NT11 and NT21 is performed by one processor 63. It is difficult to perform normally.

  However, in the case of this embodiment, the signals NT11, NT12, NT21, NT22 transmitted on the transmission line 15 indicate whether or not the opening operation is performed, and the time of the signal has a very small amount of information. The width is narrow (the time required for the processing by the processor 63 or the like is short), and it is very rare that such a collision occurs stochastically. The same signal line can be used, or each remote control receiver Even when there is only one resource, it is considered that there is almost no problem caused by collision.

  In the present embodiment, there are two signals, NT11 and NT12, transmitted from the own remote control transmitter 11A to the other remote control receiver 11B. As shown in FIG. 1, one processor is provided in the own remote control receiver 11A. In the case of a single processor configuration in which only 63 is present, signals NT11 and NT12 cannot be transmitted at the same time and collide with each other on the transmission line 15. Therefore, a signal for transmitting the signal NT11 in the transmission line 15 The need to physically separate the line and the signal line for transmitting the signal NT12 is low. However, it is natural that these signal lines may be physically separated if necessary.

  When receiving the signal N2 derived from the other operation notification signal NT21 from the input unit 65, the processor 63 writes in the other operation information flag 70 in accordance with the content of N2. Further, when the signal N2 derived from the response signal NT22 is received, as described above, it can be recognized that one unit operation has been normally completed, and the user U1 and the like can exit the buffer space 13. Or recognize that. Which recognition is obtained at this time varies depending on the timing at which the response signal NT22 is transmitted on the other remote control receiver 11B side as described above.

  Each of the remote control receivers 11A and 11B of the present embodiment performs the unit operation in cooperation with the extent that at least both of the shutter devices 14A and 14B can be prevented from being opened in the interlock function effective state. To the extent that they can be realized, it is necessary to recognize each other's operating state. Therefore, it is considered that the other operation notification signal NT21 needs at least two states. That is, there are two ways, an opening operation start state indicating that the opening operation will be started from now on, and a closed state indicating that the shutter is currently completely closed. Although the other operation notification signal NT21 can have three or more states, in this embodiment, the other operation notification signal NT21 has two states from the viewpoint of saving functions.

  As described above, when the other operation notification signal NT21 in the open operation start state is received, the shutter device on the remote controller receiver (11B for 11A) side until the next other operation notification signal NT21 in the closed state is received. Must be considered to be in an open state (pseudo-open state). If there are two other operation notification signals NT21, there are also two signals N2 derived from the other operation notification signals NT21. Also, the self-operation notification signal NT11 is the same as the other operation notification signal NT21 except that the self-remote control receiver 11A transmits it, so there are two states, the closed state and the pseudo-open state.

  Next, the output unit 66 has the same function as the output unit on the other remote control receiver 11B side described above, and outputs the self-operation notification signal NT11 corresponding to the other operation notification signal NT21 and the other-open operation instruction signal NT12. This is the output part.

  As described above, since the roles of the other remote control receivers 11A and 11B are different, the own remote control receiver 11A needs to have a function of transmitting the other opening operation instruction signal NT12 after the execution of the closing operation OP12. However, the remote control receiver 11B does not need this function. On the contrary, the other remote control receiver 11B needs to have a function of transmitting the response signal NT22 at the first transmission timing or the second transmission timing. There is no need to have a function.

  However, at the stage of manufacture, it is often not determined whether the remote control receiver product is used as its own remote control receiver or as another remote control receiver. It is necessary to install both functions in the machine 11A). If necessary, at the manufacturing stage, a remote control receiver product having only a function as its own remote control receiver and a remote control receiver product having only a function as another remote control receiver may be manufactured separately. It is natural.

  When both functions are installed, it may be necessary to make the remote control receiver recognize whether to operate as its own remote control receiver or other remote control receiver during operation. In the case of the present embodiment, the remote controller receiver is instructed to open by using the wireless signal WL1 or the like from the remote controller transmitter with sensor 16A or the remote controller transmitter 12A. Since the remote control receiver is instructed to open using NT12, the remote control receiver product can automatically recognize it.

  Of the signals NT11, NT12, NT21, and NT22 that the output unit 66 and the input unit 65 exchange with the other remote control receiver 11B via the transmission path 15, the other operation notification signal NT21 is the shutter device 14B on the other remote control receiver 11B side. Shows the operating state. The self-operation notification signal NT1 indicates the operating state of the shutter device 14A on the self-remote control receiver 11A side. Accordingly, the state of the self-operation notification signal NT1 and the signal N1 that is the basis of the self-operation notification signal NT1 are two types, that is, an opening operation start and a closing operation state (fully closed state).

  For example, when the processor 63 receives the reception processing signal RP (wireless signal WL1) for instructing the opening operation of the shutter device 14A, the automatic operation notification signal indicating the opening operation start state is output to the output unit 65 if a predetermined condition is met. A signal N1 for transmitting NT1 is supplied, and an open / close control signal CS for causing the shutter control unit 64 to perform an opening operation of the shutter is supplied. All the operations of the shutter device 14A, including whether or not this condition is met, are determined according to the stored contents of the self-operation information flag 68, the other operation information flag 70, the response reception determination unit 73, the ID registration unit 77, and the like.

  The instruction information flag 69 is a flag for writing instruction information CD corresponding to the instruction content when the processor 63 receives the reception processing signal RP (wireless signal WL1) instructing the shutter operation of the shutter device 14A. The instruction information CD has a content corresponding to a signal (for example, WL1) supplied from the remote control transmitter with sensor 16A or the remote control transmitter 12A.

  The self-operation information flag 68 is a flag for the self-remote control receiver 11A to write the self-operation information ES1 that is the operation information of the own shutter device 14A on its own side. The self-operation information ES1 may be in a completely closed state, a stopped state other than the completely closed state, or in operation.

  Next, the other operation information flag 70 indicates other operation information ES2 which is operation information of the other shutter device 14B on the other remote control receiver 11B side according to the content of the other operation notification signal NT2 received from the other remote control receiver 11B. This is a flag for writing. The other operation information ES2 is generated based on the other operation notification signal NT2 received via the input unit 65. Therefore, in the present embodiment in which the other operation notification signal NT2 has two states, the other operation information ES2 There are also two types of operation information ES2. That is, an open operation start state (pseudo-open state) indicating that an open operation is to be started from now on, and a closed state indicating that the shutter is currently in a fully closed state.

  The effective opening operation flag 67 is a component required when the remote control receiver 11A functions as another remote control receiver, and the shutter (14A in this case) disposed on the remote control receiver 11A has been described above. When moving to the effective opening operation position, the value of the stored information (effective opening operation information) MV1 is changed to a value indicating it.

  Assuming the configurations of FIG. 1 and FIG. 5, the effective opening operation flag 67 functions effectively only on the other remote control receiver 11B side, and therefore, the other remote control receiver 11B will be described as an example here. As long as the remote control receiver 11B is taken as an example, the shutter is not 14A but 14B.

  In the actual shutter device, when the user U1 sees it with the naked eye, for example, even if the shutter 14B is moved so slightly that it is not known that the opening operation has been performed, the opening operation is executed as a process inside the shutter device 14B. Although it may be recognized, in order to prevent the user U1 and the like from being confined in the buffer space 13, it is important whether or not an opening high enough for the user U1 and the like to pass through is opened. The processor 63 on the other remote control receiver 11B side changes the value of the effective opening operation information MV1 to the effective opening operation flag 67 when the height of the shutter 14B performing the opening operation reaches the effective opening operation position. To do.

  The value of the effective opening operation information MV1 has two values, a value indicating that the height of the shutter 14B has reached the effective opening operation position and a value indicating that it is not. The processor 63 of the other remote control receiver 11B can check the value of the effective opening operation information MV1 with reference to the effective opening operation flag 67 whenever necessary.

  If MV1 is a value indicating that the height of the shutter 14B has reached the effective opening position, the response signal NT22 of the second transmission timing can be transmitted based on this confirmation. From the viewpoint of the user U1 or the like, the change of the value of the effective opening operation information MV1 for the effective opening operation flag 67 and the transmission of the response signal NT22 at the second transmission timing can be performed almost simultaneously.

  When the height of the shutter 14B becomes lower than the effective opening operation position due to the closing operation, or when the shutter 14B becomes 0 (that is, when the shutter 14B is fully closed), the effective opening operation information MV1 The value is returned to the original value.

  Similarly to the valid opening operation flag 67, the response transmission unit 72 is a part that functions effectively only on the other remote control receiver 11B side.

  That is, the response transmission unit 72 is a part that functions to detect that the first transmission timing or the second transmission timing has been reached and to output the response signal NT22 from the output unit 66 at the time of detection. is there.

  Since the components other than the valid opening operation flag 67 and the response transmission unit 72 are valid on the own remote control transmitter 11A side, the description returns to the own remote control receiver 11A.

  Among the constituent elements 61 to 76, those effective only on the other remote control receiver 11B side are the constituent elements 67 and 72, and those effective only on the own remote control receiver 11A side are the constituent elements 71 and 73. Other components are effective in the other remote control receivers 11A and 11B.

  The fully closed state determination unit 71 effective on the remote control receiver 11A side is a part that determines that the shutter 14A that is executing the unit operation has completed the closing operation OP12. Based on this determination, the other opening operation instruction signal NT12 is output, and the shutter 14B starts the opening operation OP21 on the other remote control receiver 11B side.

  The response reception determination unit 73 is a part that determines whether or not the response signal NT22 has been received based on a predetermined reception determination criterion and stores the determination result DA1.

  In many cases, it can be expected that the response signal NT22 is normally transmitted from the other remote control receiver 11B at the first transmission timing or the second transmission timing and is normally received by the own remote control receiver 11A. In a case where a failure has occurred on the other remote control receiver 11B side, the response signal NT22 may not be transmitted. In this case, of course, the response signal NT22 cannot be received on the remote controller receiver 11A side.

  Even if transmission of the response signal NT22 is normally performed, the response signal NT22 may not be received on the remote control receiver 11A side due to the occurrence of a transmission error or the like. As described above, in this embodiment, since a simple configuration without a negotiation function or the like is adopted, a transmission error of the response signal NT22 is detected, and retransmission of the response signal NT22 is requested according to the detection result (error) Control (retransmission control)) is not performed. As long as error control is not performed, even if the response signal NT22 physically broken due to a transmission error caused by noise or the like is received, it is almost equal to the fact that the response signal NT22 cannot be received at all.

  There are various reception determination criteria used by the response reception determination unit 73. For example, even if a predetermined time (for example, about 10 seconds) elapses after the other opening operation instruction signal NT12 is transmitted. If the response signal NT22 cannot be received, it may be determined that the response signal NT22 could not be received. When the response reception determination unit 73 issues a determination result DA1 indicating that the response signal NT22 could not be received, the processor 63 of the own remote control receiver 11A opens the shutter 14A.

  Before the opening operation, the shutter 14A was in a completely closed state by the closing operation OP12. However, since at least the shutter 14A is opened by the opening operation, the user U1 and the like are prevented from being confined in the buffer space 13. be able to.

  When the reason why the response signal NT22 cannot be received is not a failure on the other remote control receiver 11B side but a transmission error caused on the transmission line 15 due to the influence of noise or the like, the two shutters 14A and There is a possibility that both of 14B may be in an open state and the outside air cannot be blocked, but here, the effect that can prevent the user U1 and the like from being trapped in the buffer space 13 is emphasized.

Compared with the possibility that the user U1 and the like may be trapped in the buffer space 13 when both the shutters 14A and 14B stop in a completely closed state at the time of abnormality, this embodiment is a kind of so-called fail- safe mechanism. It can be seen that there is. This is because it can be said that there is less disadvantage for the user U1 and the like when both the shutters 14A and 14B are stopped in the fully closed state than when both are stopped in the open state.

  The counter display unit 74 connected to the processor 63 is a part that displays and outputs the number of opening / closing operations of the shutter 14A. Specifically, for example, a 7-digit display device in which seven 7-segment display devices (for example, 7-segment LED) are arranged may be used. In order to inform the user U1 of the maintenance time and the like, and to inform the user U1 of the normality of the operation of the shutter device 14A, it is necessary to display the number of such opening / closing operations.

  By the way, in this embodiment, the function of the counter display unit 74 is utilized to set specification items that define the operation specifications of the shutter device 14A. This specification item includes not only the shutter device 14A but also a specification item related to the specification of the cooperative operation between the shutter device 14A and its peripheral devices (for example, the sensor-equipped remote control transmitter 16A). A predetermined interface circuit is interposed between the peripheral device and the shutter device 14A as necessary.

  In setting the specification items, it is necessary to make various settings depending on the type of the peripheral device and the environment in which the shutter device 14A and the peripheral device are installed. On the other hand, the composite shutter system 10 is limited. Therefore, it is necessary to efficiently set specification items while saving functions.

  As an example of the specification item, for example, when the shutter device 14A is installed in an area with a lot of snowfall, if the remote control transmitter with sensor 16A is installed outdoors, the transmissive optical sensor reacts to snow falling. In order to prevent erroneous detection that the user U1 or the like has appeared, the user U1 or the like is set to be detected only when the light is continuously blocked for a predetermined time (light-shielding time) or longer. It is done.

  Also, in factories that handle hazardous materials, a setting is made to sound a buzzer (not shown) that always emits a warning sound before the shutter 14A operates, or a predetermined time has elapsed since the operation was instructed. The shutter 14A may be set to operate.

  Conventionally, many dip switches are arranged on the control panel and the specification items are set by switching each dip switch. However, such a configuration basically requires dip switches according to the number of specification items, so as the required settings diversify, the number of necessary dip switches increases and the control panel becomes larger. There was a problem.

  Therefore, in the present embodiment, a software variable (parameter) is used instead of the DIP switch.

  Assuming that one specification item corresponds to one variable, each time the specification item is set, the variable is called and a display corresponding to the called variable is displayed on the counter display unit 74. The value set during this display is processed as a set value for that variable (its specification item).

  The setting processing unit 76 has a function of calling such a variable and displaying it on the counter display unit 74, or processing a value set during display as a setting value for the variable. Calling a desired variable can be performed by repeatedly pressing the operation switches 51 to 53 in combination. If necessary, a fixed operation unit or a remote control transmitter that has more operation switches than the remote control transmitter 12A and is convenient for setting may be prepared.

  In any case, the user interface that can be used for setting is extremely limited as compared with a personal computer equipped with a bitmap display, a mouse, a keyboard, and the like. The calling procedure executed using 53 or the like can be quite complicated. Various rules necessary for setting the details of the calling procedure should be documented in a manual or the like. In addition, it may be documented and distributed as to which variable (which specification item) the character or number displayed on the counter display unit 74 corresponds to.

  Here, as an example, it is assumed that “EPH-086” shown in FIG. 8 is displayed on the counter display unit 74.

  In this case, “EPH” is a variable name (variable name) for uniquely identifying each variable in the remote control receiver 11A, and “086” is a value set by the user U1 for this variable EPH. Is shown. The symbol “-” is an operator indicating assignment of a value to a variable. If possible, “=” or the like may be used as a symbol indicating substitution. However, since it is difficult to display “=” with a 7-segment LED, “−” is substituted. Of course, a number corresponding to the variable name may be displayed instead of the variable name.

  A user or a maintenance person of the shutter device 14A performs desired procedures while viewing the document and performs a desired setting. The values set for each variable are stored in the setting storage unit 75 as the value of the specification item.

  With such a configuration, since a dip switch is not required, the control panel will not be enlarged even if the number of specification items increases. Moreover, even if the specification items are changed or increased, there is no need for hardware changes, and it is possible to flexibly respond by simply replacing the software.

  The ID registration unit 77 is a part that performs the above-described ID registration (ID storage) in response to the ID registration operation.

  Among the above components, the flags 67, 68, 69, and 70 need only function when the composite shutter system 10 is operated (when power is supplied), and thus a normal RAM (random access memory) is used. However, the setting storage unit 75 and the ID registration unit 77 need to maintain the stored contents even when the power is not supplied and prepare for the resumption of the power supply. Therefore, the setting storage unit 75 and the ID registration unit 77 may use a writable ROM (read-only memory) such as an EEPROM (flash memory: Electrical Erasable Programmable ROM). In order to perform strict control, it is desirable that the effective opening operation flag 67 and the response reception determination unit 73 are also composed of an EEPROM or the like.

  However, if necessary, the ROM can be replaced with a magnetic storage means, a RAM having a sufficient power backup mechanism, or the like. In general, the price of the memory itself is higher in the EEPROM than in the RAM, but considering the power consumption for backup and the like, the operation cost is likely to be higher in the RAM. In actual implementation, an advantageous one may be selected in consideration of these points.

  Hereinafter, the operation of the present embodiment having the above configuration will be described with reference to the flowcharts of FIGS.

  FIG. 6 is a flowchart showing an operation for realizing the unit operation, and includes steps S10 to S20. FIG. 7 is a flowchart showing an operation when setting the specification item, and includes steps S30 to S36.

  Note that FIG. 6 employs the first transmission timing described above as the timing for transmitting the response signal NT22.

(A-2) Operation of Embodiment First, an operation for realizing a unit operation will be described with reference to FIG.

(A-2-1) Operation for Unit Operation As a premise, it is assumed that the interlock function is in an effective state and the processing starts from a state in which both shutters 14A and 14B are completely closed.

  At this time, for example, when the remote control transmitter with sensor 16A detects the user U1 or the like approaching the shutter 14A from the inside of the factory 8, a signal (for example, WL1) instructing the opening operation is automatically received by the remote control. To the machine 11A. When the remote control receiver 11A receives this signal and detects an opening operation instruction (S10), the shutter 14A is opened (OP11) (S11), and then the motor is automatically reversed to the closing operation OP12 (S12). Further, since the interlock function is effective, when starting the opening operation OP11 in step S11, the own remote control receiver 11A transmits the automatic operation notification signal NT11 in the pseudo-open state, and the other remote control receiver 11B receives the shutter. It is prohibited to open 14B. Therefore, at this time, for example, even if the user U2 or the like instructs the other remote control receiver 11B to perform the opening operation, the opening operation is not executed.

  There can be various inversion execution timings for switching from the opening operation OP11 to the closing operation OP12, but an opening high enough for the user U1 or the like to pass through may be opened for a time sufficient for the passage. It becomes a condition. This height and time can also be set in advance according to the request of the user U1 and the like. Of course, the variable EPH can also be used for this setting.

  When the closing operation OP12 in step S12 is completed and the shutter 14A is completely closed, the remote controller receiver 11A transmits the other opening operation instruction signal NT12 (S13). The transmitted other opening operation instruction signal NT12 is received by the other remote control receiver 11B via the transmission line 15 (S14).

  It is desirable that the remote controller receiver 11A transmit the other opening operation instruction signal NT12 when the shutter 14A is completely closed as described above in order to shut off the outside air. Accordingly, it may be transmitted before the fully closed state (in the middle of the closing operation OP12). If the distance between the shutters 14A and 14B is shorter than the moving speed of the user U1 or the like, the user U1 must stop in the buffer space 13 and wait for the shutter 14B to open unless the timing is set. This is because there is a possibility that it will be lost.

  In addition, since the interlock function is effective, when transmitting the other opening operation instruction signal NT12, the own remote control receiver 11A also transmits the closed state automatic operation notification signal NT11. The transmission of the notification signal NT11 may be omitted.

  The self-operation notification signal NT11 in the closed state is a signal for notifying that the other remote control receiver 11B may perform the opening operation if the opening operation is instructed by the user U2 or the like thereafter. Since the other opening operation instruction signal NT12 is a signal that forcibly causes the other remote control receiver 11B to perform the opening operation regardless of whether there is an opening operation instruction from the user U2 or the like, the other opening operation instruction signal NT12 is transmitted. This is because there is almost no need to transmit the self-operation notification signal NT11 in the closed state.

  When receiving the other opening operation instruction signal NT12 in step S14, the other remote control receiver 11B causes the shutter 14B to open operation OP21 (S15), and then automatically reverses the motor to perform the closing operation OP22 (S16). Step S15 corresponds to step S11, and step S16 corresponds to step S12.

  Therefore, with respect to the opening operation OP21 and the closing operation OP22, the variable EPH is used in advance so that an opening having a height high enough for the user U1 or the like to pass through is opened for a time sufficient for the passage. Can be set. This set value may be the same as that of the own remote control receiver 11A, but may be different.

  Even if the remote control receivers 11A and 11B are connected to each other through the transmission line 15, they are separate devices and need to be set separately. The operation specifications of the other remote control receivers 11A and 11B are different. If necessary, the other remote control receivers 11A and 11B may share the same setting value via the transmission line 15.

  Whether the opening operation OP21 is executed immediately after receiving the other opening operation instruction signal NT12 or after a predetermined delay time has elapsed can be determined by setting using a variable EPH or the like. From one shutter device (for example, 14A), the other shutter device (for example, 14B) can be regarded as a kind of the peripheral device described above.

  FIG. 6 employs the first transmission timing described above as the timing for transmitting the response signal NT22, so that the other remote control receiver 11B transmits the response signal NT22 after the completion of the closing operation OP22 in step S16. (S17).

  In the remote controller receiver 11A, after transmitting the other opening operation instruction signal NT12 in the step S13, it is determined whether or not the response signal NT22 can be received within 10 seconds from the transmission. Is inspecting (S18).

  Since the other opening operation instruction signal NT12 is transmitted, the shutter 14B must be considered open until the response signal NT22 can be received. Therefore, the operation is the same as when the other operation notification signal NT21 is received. Even if the remote control receiver 11A receives a new opening operation instruction from the remote control transmitter with sensor 16A or the like, it does not respond to it. This is a process according to the interlock function.

  If the response signal NT22 is received within 10 seconds, the step S18 branches to the YES side, and the own remote control receiver 11A recognizes the completion of the unit operation (S19). By this recognition, the own remote control receiver 11A becomes ready to respond to a new opening operation instruction (such as WL1) received from the sensor-equipped remote control transmitter 16A. Therefore, when a new user or a processed product actually moves in front of the remote controller transmitter with sensor 16A and is detected by the sensor, the same unit operation is repeated again.

  However, in rare cases, the response reception determination unit 72 in the own remote control receiver 11A may determine that the response signal NT22 could not be received within the 10 seconds. In this case, since the step S18 branches to the NO side, the remote controller receiver 11A opens the shutter 14A and performs an abnormal termination process (S20).

  As described above, the opening operation is a process for preventing the user U1 and the like from being confined in the buffer space 13, but is a process contrary to the interlock function.

  Such a case rarely occurs, but there is a failure on the other remote control receiver 11B side, the influence of noise is abnormally increased, or the transmission line 15 is physically disconnected. It may occur due to some reason. In any case, since it is not preferable to leave such a state, it is preferable to issue an alarm by a method such as a buzzer or blinking of a warning lamp so as to prompt investigation and elimination of the cause. Raising such a warning can also be included as part of the abnormal termination process.

  Note that the opening operation instruction in step S10 was automatically transmitted from the sensor-equipped remote control transmitter 16A that detected the user U1 or the like, but this was received by the user U1 with the hand of the remote control transmitter 12A. Of course, the radio signal WL1 transmitted by operating the operation switch 51 may be replaced.

  In this case, the operation burden on the user U1 is slightly generated, but only by instructing the opening operation to the first one remote control receiver 11A, a series of the unit operations are performed on the other remote control receivers 11A and 11B. Since it can be executed and can pass through the buffer space 13 including the shutters 14A and 14B, the operation load is small and the processing is efficient. In that case, there is also an advantage that the remote controller transmitter with sensor 16A can be omitted.

  In the above description, the one-way passage along the passing direction PD1 has been described. However, the composite shutter system 10 of the present embodiment can automatically cope with the passing direction PD2 opposite to the PD1. This is as described above.

  That is, the remote controller receiver is instructed to open by using the wireless signal WL1 or the like from the remote control transmitter with sensor 16A or the remote controller transmitter 12A, and is opened using the other open operation instruction signal NT12 via the transmission line 15. Since it is understood that it is the other remote control receiver that is instructed to operate, each remote control receiver 11A, 11B should be operated as its own remote control receiver or other remote control receiver each time. It can be automatically recognized.

  Next, the operation when setting the specification items will be described with reference to FIG. Here, the setting for the own remote control receiver 11A will be described as an example. The setting for the other remote control receiver 11B is the same as this.

(A-2-1) Specification Item Setting Operation In FIG. 7, in the initial state, the counter display unit 74 displays the number of operations of the shutter 14A (S30).

  In this state, the setter (for example, user U1) executes the above-described calling procedure for calling a desired variable (desired specification item) using the remote control transmitter 12A or the like while referring to the document, for example. Then, the own remote control receiver 11A detects it (S31), and displays the variable name corresponding to the detected calling procedure on the counter display unit 74 (S32).

  At this time, only “EPH”, for example, is displayed as the variable name, and the setting value (“086” in the example of FIG. 8) is a predetermined initial value (for example, “000”) or default A value (eg, “055”) is displayed. At this time, the initial value and the default value may be blinked to notify the user U1 that a change in the value is awaited (S33).

  When the setting procedure is executed by the user U1 operating the remote control transmitter 12A or the like while referring to the document, for example, in the example of FIG. 8, the setting value of 3 digits may be changed and confirmed one by one. Yes (S34). By repeating such a setting procedure one digit at a time, a desired setting value (here, “086”) can be set as the setting value of the variable EEH.

  By referring to the document, the user U1 knows what the number “086” (or each digit) means. As an example, when “086” has a meaning as a number as it is, for example, the shading time for identifying the snow and the user U1 may be shown in units of 1/100 second. In this case, it is determined that the user U1 or the like has been detected only when the light is continuously shielded for 0.86 seconds or longer.

  When the values of all three digits are confirmed and the user U1 performs a predetermined confirmation operation, the setting processing unit 76 in the own remote control receiver 11A detects that fact (S35), and sets the set value as a variable (here) Then, the setting storage unit 75 stores the set value for EPH) (S36).

  With this storage, in subsequent operations, the own remote control receiver 11A performs an operation corresponding to the set value (“086”) with respect to the specification item corresponding to the variable EPH.

  Further, after the storage in step S36 is executed, the display content of the counter display unit 74 returns to the number of operations of the shutter 14A (S30). At this time, in order to display the number of shutter operations before the execution of step S31, information on the number of operations may be stored in a predetermined storage area.

  In some cases, the setting procedure or the calling procedure can be made more efficient by making it possible to continuously perform the setting for a plurality of variables without returning to step S30 every time the setting for the variable is performed. It is good to have a procedure for that.

(A-3) Effect of Embodiment According to the present embodiment, the user (U1) only instructs the shutter device (14A) to perform an opening operation at most once, and the two shutter devices (14A, 14B) Since the unit operation can be executed to pass through the buffer space (13), the operation load is small and the convenience is high.

  Further, in this embodiment, if the number is small, it is only necessary to install one remote control transmitter (16A) with a sensor, so that the number of components constituting the composite shutter system (10) is small and efficient.

Furthermore, in this embodiment, when the response signal (NT22) cannot be received, the remote controller receiver (11A) opens the shutter (14A), so that even in the worst case, the user (U1) can use the buffer space. Therefore, a fail- safe mechanism can be realized.

(B) Other Embodiments In the above embodiment, the radio signal WL1 is a weak radio wave having a frequency band of about 300 MHz or 400 MHz and a transmission power of about 1 mW, but the scope of application of the present invention is limited to this. Is not to be done. Higher and lower frequency radio waves may be used, and infrared rays may be used. Further, the transmission power may be larger or smaller than this.

  Further, in the above-described embodiment, the interlocking relationship of the operation related to the opening / closing of the shutter is held in a predetermined manner, but if necessary, the interlocking relationship regarding the operation other than the opening / closing of the shutter is maintained. May be.

  Furthermore, in the above-described embodiment, it is a condition for maintaining the interlocking relationship that one of the shutters is in the closed state, but such a condition is inevitably determined from the contents of the interlocking relationship to be maintained. Is.

  In the above embodiment, since the purpose is to block outside air, it is necessary to prevent the two shutter devices from being simultaneously opened. However, depending on the purpose, the two shutter devices are prevented from being simultaneously closed. It may be necessary. The present invention is also applicable to such a case. In that case, it is necessary to replace the opening and opening operations in the description of the above embodiment with closing and closing operations, and to read the closing and closing operations with opening and opening operations.

  Also in this case, the other opening operation instruction signal NT12 instructing the other remote control receiver 11B to perform the opening operation can be replaced with another closing operation instruction signal instructing the other remote control receiver 11B to perform the closing operation.

  Further, the opening / closing operation means a moving operation only in the opening direction, only in the closing direction, or in both opening and closing directions. In addition, “closed” is a concept that means movement in a direction to close an opening when it exists, means forward movement of the opening / closing body including feeding, sliding movement, extension, etc. "Is a concept that means movement in the direction of opening the opening when it exists, and means retraction of the opening / closing body including winding, contraction, folding, and the like.

  In the above embodiment, the number of functions installed in the remote control transmitter is reduced as much as possible and as many functions as possible are distributed to the remote control receiver. If necessary, the functions installed in the remote control receiver are used. It is also possible to adopt a configuration in which a part of is mounted on the remote control transmitter side.

  Furthermore, in the above embodiment, the operation switch is a PBS type switch, but the present invention is not limited to the PBS type switch. A slide-type switch, a rotary switch, or the like may be used, and various switches that react to changes in pressure, temperature, static electricity, and the like can also be applied.

  Regardless of the above embodiment, the occurrence of the collision can be prevented by utilizing an indivisible instruction such as a so-called TS (test and set) instruction.

  The 7-segment display device used in the counter display unit 74 can be replaced with a device that displays characters, numbers, symbols, and the like by a method other than the 7-segment method.

  In the above-described embodiment, the present invention is mainly applied to the sheet shutter. However, the present invention can be applied to various shutters such as a garage shutter and a window shutter in addition to the sheet shutter.

  Further, the present invention can be applied not only to a shutter but also to a mixed system of other opening / closing devices such as doors, windows, overhead doors, roll screens (for example, light shielding curtains), blinds, awning devices.

  In the above description, the direction of information flow is basically a unidirectional direction from the remote control transmitter to the remote control receiver (remote control receiver 11), but the scope of application of the present invention is such a unidirectional direction. It is not limited to communication.

  That is, the remote control transmitter is replaced with an operation transmitter / receiver that is a remote operation transmitter / receiver instead of a transmission dedicated communication device, and the remote control receiver is not a reception dedicated communication device but a remote operated transmitter / receiver. It may be replaced with an operated transceiver to perform full-duplex communication or half-duplex communication as necessary.

  At this time, the signal included in the radio signal from the operation transmitter / receiver to the operated transmitter / receiver may be an operation state instruction signal instructing the shutter operation or the like, or a signal instructing switching of the interlock function. The signal included in the radio signal from the operated transceiver to the operation transceiver may be an operation state report signal for reporting the current state of the shutter operation.

  The operation state report signal indicates that the shutter operation state at that time is, for example, “fully open state”, “fully closed state”, “partially open state (partially opened and stopped)”, “ It may be a signal indicating that “opening operation”, “closing operation”, “abnormality occurrence”, or the like.

  In this case, by receiving the operation state report signal, the user of the operation transceiver can recognize that the shutter operation state is, for example, the “closing operation”.

  In addition, the operation transceiver can be replaced with a portable receiver, and the operated transceiver can be replaced with a fixed transmitter. In this case, the information flows in a single direction from the fixed transmitter toward the portable receiver. A system configuration in which only such unidirectional communication is always performed may be employed, or a system configuration in which such unidirectional communication can be performed only when necessary in accordance with communication direction mode switching.

  That is, the operation transmitter / receiver and the operated transmitter / receiver may be configured to perform such unidirectional communication only when necessary according to the communication direction mode switching.
