Can do.

(A) Embodiments Hereinafter, embodiments of an opening / closing device, an opening / closing method, and an opening / closing program according to the present invention will be described with reference to the drawings.

  In this embodiment, in an electrically operated opening / closing system of a slat shutter that opens and closes up and down, the opening / closing device and the opening / closing method according to the present invention are applied to the device that controls the opening / closing operation of the shutter curtain, and the control that realizes the function of the opening / closing device A program in which the opening / closing program of the present invention is applied to a program executable by the unit will be described.

(A-1) Configuration of Embodiment In the following, first, after an example of the overall configuration of the electric opening / closing system according to the present embodiment, there is a predetermined operation for restricting the opening / closing body operation in response to a user operation instruction. A configuration example of a storage processing device that stores the input combination information and a configuration example of a remote control transmitter will be described.

(A-1-1) Overall Configuration Example FIG. 2 is a configuration diagram illustrating an overall configuration example of the electric switching system according to the present embodiment.

  In FIG. 2, the electric switching system 10 according to the present embodiment is roughly divided into a storage processing device (including a remote control receiver) 11, a remote control transmitter 12 that can communicate with the storage processing device 11, a shutter curtain 13, A fixed operation unit (operation panel) 14, a guide rail GR, and a shutter case SC1 are provided at least.

  Here, the electric opening / closing system 10 of the present embodiment includes, for example, a wired remote control system that opens and closes according to an operation instruction from the fixed operation unit 14 by a user operation, and an operation instruction from, for example, a remote control transmitter 12 possessed by the user. This is combined with a wireless remote control system that opens and closes.

  Of course, the present invention can also be applied to an open / close system that operates only with a wired remote control system or only with a wireless remote control system.

  Here, the wired remote control system is one form of a system that remotely controls the operation of the opening / closing body, and refers to a system that instructs the operation of the opening / closing body by wired communication. The wireless remote control system is a form of a system that remotely controls the operation of the opening / closing body, and refers to a system that instructs the operation of the opening / closing body by wireless communication.

  Therefore, the user U1 operates the fixed operation unit 14 or the remote control transmitter 12 to instruct a desired shutter operation (opening operation or closing operation (including changing the intermediate position as necessary)). Can do.

  Various modes can be considered for the operation instruction mode of the electric shutter by user operation, but the present invention can be applied to any mode. For example, as an example of the operation instruction mode, for example, a limited operation mode for maintaining the opening / closing body operation while the user continues to press the operation switch, or for example, after the user presses the operation switch, However, an unrestricted operation mode in which the opening / closing body operation is automatically maintained can be considered.

  In FIG. 2, a shutter curtain 13 is a robust opening / closing body constructed by connecting a number of metal slats made of, for example, iron, and is used for, for example, disaster prevention or crime prevention. In this embodiment, the shutter curtain is described as an example of a shutter curtain. However, the shutter curtain is not limited to this. For example, the shutter curtain is made of a light material such as polyester, a panel shutter, or a grill shutter. It can also be applied to.

  When the shutter curtain 13 receives an opening operation instruction from a controller (not shown), a power source (not shown) is driven, and the shutter curtain 13 is taken up by a take-up shaft (not shown), and the shutter curtain 13 It is stored in. At this time, the shutter curtain 13 moves along the guide rail GR provided on the wall WL in the direction of the arrow D2 (upward), and the lower end 13A opens the opening.

  Further, when the shutter curtain 13 receives a closing operation instruction from the control unit, the power source is driven, and the wound shutter curtain 13 is separated from the winding shaft and along the guide rail GR in the direction of the arrow D1 ( The shutter curtain lower end 13A, which is the closing side end of the shutter curtain 13, moves in the downward direction and closes the opening.

  FIG. 2 shows a case where the shutter curtain lower end portion 13A is stopped at an intermediate position between complete closing and complete opening.

  The shutter curtain lower end 13A and the shutter case SC1 have infrared ports PR1 and PR2 as an obstacle detection system.

  The infrared ports PR1 and PR2 contribute to obstacle detection, and when the shutter curtain lower end portion 13A comes into contact with an object, the infrared port PR1 transmits infrared rays. In addition, when the infrared port PR2 receives infrared rays from the infrared port PR1, the infrared processing port PR2 gives a signal indicating that the infrared rays have been received to the storage processing device 11.

  Here, in the present embodiment, an aspect in which infrared rays are used as an obstacle detection signal transmission medium is shown, but the present invention is not limited to this, and other wireless communication media such as light rays and radio waves may be used. Alternatively, a wired communication medium may be used.

  The fixing operation unit 14 is, for example, fixedly installed in the vicinity of the shutter curtain 13, and instructs and operates the opening / closing operation of the shutter curtain 13. The fixed operation unit 14 has operation switches represented by, for example, a three-point push button switch (PBS) of an open switch, a stop switch, and a close switch, and when the user presses these operation switches, the fixed operation unit 14 opens. A signal for instructing a stop operation and a close operation is given to the memory processing device 11.

  The remote control transmitter 12 is a wireless device that instructs the opening / closing operation of the shutter curtain 13, and an appearance example thereof is shown in FIG. In FIG. 3, the remote control transmitter 12 has three operation switches 51 to 53 in the PBS format protruding from the upper surface of the main body 12A. When these operation switches 51 to 53 are pressed by the user, the remote control transmitter 12 creates a radio signal having a user operation signal according to a predetermined modulation process, and transmits the radio signal.

  In FIG. 3, an operation switch 51 is an opening operation switch for instructing an opening operation of the shutter curtain 13, and an operation switch 52 is a closing operation switch for instructing a closing operation of the shutter curtain 13. Is a stop switch for stopping the opening or closing operation of the shutter curtain 13 at an arbitrary timing.

  Although details of the functional configuration will be described later, the storage processing device 11 receives an operation instruction signal from the fixed operation unit 14 or the remote control transmitter 12, receives a signal from an upper limit or a lower limit, or an infrared port PR2. Receiving an obstacle detection signal from the sensor, receiving temperature information from a temperature sensor that senses the temperature of a power source (for example, a motor), and controlling the operation of the shutter curtain 13 based on these received signals. is there.

  In addition, when there is an input with a high priority order that restricts the operation of the shutter curtain 13 that is instructed by the user, the storage processing device 11 stores the input combination information of the input signals at that time. In other words, when an event that invalidates the operation instructed by the user occurs, the storage processing device 11 regards this as abnormal, and records the input status of the input signal at that time as a history.

  As a result, a case where there is an input that restricts the operation of the shutter curtain 13 can be recorded as a history. Therefore, the signal system of the input signal that causes a failure can be estimated based on the history information, so that the accuracy can be accurately determined. Can be expected to perform maintenance work.

  Hereinafter, the configuration and function of the storage processing device 11 will be described in detail with reference to the drawings.

(A-1-2) Configuration Example of Storage Processing Device FIG. 1 is a configuration diagram showing the relationship between a configuration centered on a control unit that controls the functions of the storage processing device 11 and peripheral devices.

  As shown in FIG. 1, the system configuration of the present embodiment includes a control unit 43 that controls the functions of the storage processing device 11, a fixed operation unit 14, a limit position storage unit 21, a comparison unit 22, and a counter unit 23. Timer unit 24, infrared receiving unit (PR2) 25, motor control unit 26, temperature sensor unit 27, storage management unit 28, connector unit 29, log storage unit 30, wireless receiving unit 41, A reception processing unit.

  The control unit 43 serves as a function of the storage processing device 11 and includes, for example, a CPU, a ROM, a RAM, an EEPROM, and the like, and corresponds to, for example, a microcomputer.

  The control unit 43 is connected to the fixed operation unit 14, the reception processing unit 42, the comparison unit 22, the infrared reception unit (infrared port PR2) 25, the temperature sensor unit (TH1) 27, the timer unit 24, and the like. A signal for instructing the operation of the shutter 13 or a signal for informing the state of the shutter curtain 13 is received, and a signal for controlling the operation of the shutter curtain 13 is given to the motor control unit 26 based on the input of these signals.

  In addition, the control unit 43 includes an input monitoring unit 43A that monitors the status of signal input from the above-described configuration requirements. The input monitoring unit 43A has a preset abnormality determination table 43B. When the combination of input signals input from the above-described configuration requirements matches the combination set in the abnormality determination table 43B, the shutter curtain 13 It is determined that there has been an input that restricts the operation of (i.e., abnormal), and the input combination information is recorded in the log storage unit 30 through the recording management unit 28 as a history.

  Here, a configuration example of the abnormality determination table 43B will be described with reference to FIG. The abnormality determination table 43B shows an example of a relationship between a certain operation instruction for the shutter curtain 13 and an operation instruction having a higher priority than restricting the operation. Of course, contents other than these can be set.

  For example, in the configuration example of the abnormality determination table 43B in FIG. 7, the input of “upper limit signal”, “lower limit signal”, “open signal”, “close signal”, “stop signal”, and “obstacle detection signal”. The presence or absence is an item. In FIG. 7, a signal input to the control unit 43 is indicated as “ON”, and a case where no signal is input to the control unit 43 is indicated as “OFF”.

  For example, it is assumed that an input instruction of “upper limit signal, lower limit signal, obstacle detection signal” has a higher priority than a user operation instruction of “open signal, closed signal”. It is assumed that “stop signal” has a higher priority than “signal, lower limit signal, obstacle detection signal”.

  Therefore, for example, “abnormality No. 1” is a case where the user attempts to close the shutter 13 that is in the open state of the upper limit position or more, but even if “close signal: ON” is given to the control unit 43. , “Obstacle detection signal: ON” having a higher priority is given, and “close operation” is restricted.

  “Abnormal No.” is number information for determining the combination pattern when the input combination of each signal of the table item matches, and in the present embodiment, this number information is stored in the log storage unit 30. Try to remember. That is, when the input monitoring unit 43A detects the signal input of the input combination defined in the abnormality determination table 43B, the “abnormality NO.” Related to the input combination is given to the storage management unit 28 and stored in the log storage unit 30. . After that, the maintenance worker outputs the stored “abnormality NO.”, And based on the “abnormality NO.”, The management table of which signal is “ON” and which “OFF” is on hand. From the above, it is possible to actively maintain the signal system that causes the failure.

  Further, “abnormal content” indicates the content of the abnormality when there is an input in the input combination of each signal of the table item. In the present embodiment, for convenience of explanation, this item is a table item. However, this item may be omitted if the maintenance worker can know the content of the abnormality.

  In the present embodiment, it is assumed that an abnormality history is taken when each input signal is input to the control unit 43 with a prescribed input combination in the abnormality determination table 43B. When an operation indicated by some user operation instruction signal is invalidated, all input states of the input signal input to the control unit 43 at that time may be recorded as a history.

  In the present embodiment, “invalidate the operation indicated by the user operation instruction signal” is, for example, whatever the operation instruction signal from the operation instruction means such as “open signal: ON” is input to the control unit 43. In addition to not controlling the operation (that is, maintaining the previous state), for example, even if “open signal: ON” is given from the control unit, “stop operation control”, “close operation control”, etc. It is a concept that includes operation control different from the operation control indicated by the signal given from the control unit, and it is also possible to change the operation mode, change the operation range, change the operation speed, etc. It is a concept that includes Further, the invalidation method may be different depending on the combination pattern.

  Returning to FIG. 1, the wireless reception unit 41 includes, for example, a reception antenna system, a filter circuit, a power amplifier, and the like, receives the wireless signal WL1 wirelessly transmitted by the remote control transmitter 12, and is included in the received wireless signal WL1. The received signal WS corresponding to the transmitted signal WS is given to the reception processing unit 42.

  The reception processing unit 42 receives the reception signal WS from the wireless reception unit 41 and supplies the reception processing signal PR subjected to necessary processing such as predetermined decoding processing and demodulation processing to the control unit 43.

  The fixed operation unit 14 gives an operation instruction signal operated by the user to the control unit 43.

  The motor control unit 26 receives a control signal S26 for controlling the operation of the shutter curtain 13 from the control unit 43, and drives the motor M1 that is a power source in accordance with the control signal S26.

  The motor control unit 26 also has a function of outputting an encoder pulse S26A indicating the rotation of the output shaft of the motor M1, and supplies the encoder pulse S26A to the counter unit 23. The amount of rotation of the output shaft of the motor M1 varies depending on the number of encoder pulses S26A, and the amount of rotation of the output shaft of the motor M1 corresponds to the amount of movement of the shutter 13 (that is, the lower end portion 13A).

  The counter unit 23 receives the encoder pulse S26A from the motor control unit 26, counts the number of the encoder pulses, and gives the count value to the comparison unit 22.

  The limit position storage unit 21 includes information (upper limit position position data LUP) indicating an upper limit position (upper limit) in the movement range of the lower end portion 13A, and information (lower limit position data LUN) indicating a lower limit position (lower limit). Is memorized. The limit position storage unit 21 stores information indicating a predetermined intermediate position between the upper limit position and the lower limit position, and information indicating a position where the upper limit position and the lower limit position are overrun by a predetermined slight distance. Is also possible.

  The comparison unit 22 compares the count value CT1 given from the counter unit 23 with the limit position data LUP and LUN stored in the limit position storage unit 21, so that the shutter curtain lower end 13A is at the upper limit position or the lower limit position. The detection result is given to the control unit 43 as an upper limit signal or a lower limit signal.

  Here, as a method for recognizing the position (for example, the upper limit position or the lower limit position) of the shutter curtain lower end portion 13A, a continuous count method and a discontinuous count method are conceivable, and FIGS. A brief description will be given with reference.

  In the continuous counting method, the count value at the end of the previous shutter operation is stored (for this storage, for example, nonvolatile storage means such as EEPROM (Electrical Erasable Programmable ROM) is used) and this shutter is used. This is the count value at the start of operation.

  On the other hand, the discontinuous counting method does not store the count value at the end of each shutter operation, but resets the count value at the start to a certain initial value (here, this is set to 0) for each shutter operation. It is.

  6A is an explanatory diagram showing an operation example of the continuous counting method, and FIG. 6B is an explanatory diagram showing an operation example of the discontinuous counting method, both of which are opened from the fully closed state (EA1). , EB1) to move to the fully open state, and further to the closed state (EA2, EB2) from the fully open state to move to the fully closed state.

  In appearance, the fully closed state is the state shown in FIG. 5C, and the fully open state is the state shown in FIG. An example of an intermediate state (intermediate position) between the fully closed state and the fully open state is the state shown in FIG.

  In the case of the continuous count method, in the example of FIG. 6A, the upper limit position position data LUP stored in the limit position storage unit 21 is “10000”, and the lower limit position position data LUN is “0”.

  On the other hand, in the case of the discontinuous count method, in the example of FIG. 6B, the upper limit position position data LUP stored in the limit position storage unit 21 is “10000” and the lower limit position position data LUN is “−10000”. It is.

  However, the counting of the encoder pulse S26A by the counter unit 23 is a process of incrementing (+1) each time the encoder pulse S26A is supplied in the opening operation in which the shutter curtain lower end 13A moves in the direction of the arrow D2. On the contrary, in the case of the closing operation that moves in the direction of the arrow D1, it is a process of decrementing (−1) each time the encoder pulse S26A is supplied.

  In order to notify the counter unit 23 whether to increment or decrement, the control unit 43 informs the counter unit 23 whether the instruction indicated by the signal S26 is an opening operation or a closing operation of the shutter curtain 13. Good.

  In addition, the control unit 43 informs the comparison unit 22 whether the instruction designated by the signal S26 is an opening operation or a closing operation of the shutter curtain 13, and the target to be compared with the count value CT1 is the upper limit position data LUP. It may be specified whether there is a lower limit position data LUN.

  Thus, by using the function of the comparison unit 22, the control unit 43 can recognize that the shutter curtain lower end portion 13 </ b> A has reached the upper limit position or the lower limit position, so the opening operation or the closing operation of the shutter curtain 13 is the upper limit. By automatically stopping at the position or the lower limit position, the above-described unrestricted operation mode can be realized.

  The control unit 43 can also recognize that the shutter curtain lower end 13A has reached the lower limit position without using the function of the comparison unit 22. For example, a method using the signal S25 supplied from the infrared receiving unit 25 can be considered. In addition, for example, by preparing the two methods described above, the control unit 43 normally stops at the lower limit position using the function of the comparison unit 22, and in an emergency (when a failure occurs, the comparison unit 43 When the normal signal S22 is not supplied from the signal 22), the stop at the lower limit position can be performed based on the signal S25.

  The infrared receiving unit 25 has an infrared port PR2, and receives the infrared IRD output from the infrared port PR1 provided at the shutter curtain lower end 13A. When receiving the infrared IRD, the infrared receiving unit 25 gives a signal S25 to the control unit 43 in order to notify that.

  As described above, the infrared IRD is output from the infrared port PR1 when the shutter curtain lower end 13A during the closing operation comes into contact with the object. Assuming a general operating situation of the shutter curtain 13, the object with which the shutter curtain lower end 13 </ b> A comes into contact is almost always the floor surface FL, but in rare cases it comes into contact with an unexpected object (obstacle). There is. The contact between the floor FL and the shutter curtain lower end portion 13A is an event that occurs every time the shutter curtain 13 is completely closed by the closing operation, whereas the contact with the unexpected object is caused by the shutter curtain 13 This is an event that occurs only when an unexpected object appears on the trajectory of the shutter curtain 13 (the traveling direction of the lower end portion 13A) during the closing operation.

  As described above, in order to cause the control unit 43 to stop at the lower limit position based on the signal S25 only in an emergency, the shutter curtain lower end portion 13A is placed on the floor surface FL as the value of the lower limit position position data LUN. It is preferable to set a value indicating a position slightly higher than the position where the infrared IRD is output upon contact. Thus, the control unit 43 can normally stop the shutter curtain 13 automatically based on the signal S22, and can stop (emergency stop) the shutter curtain 13 based on the signal S25 in an emergency.

  The temperature sensor unit 27 detects the temperature of the motor M1 and gives the detected temperature information to the control unit 43. Here, the temperature information provided by the temperature sensor unit 27 may be, for example, a measured value of the temperature related to the motor M1 measured constantly or at a constant cycle. For example, the measured value of the temperature of the motor M1 is a predetermined threshold value TH1. The temperature sensor unit 27 may determine whether or not the threshold value has been exceeded, and the signal S27 may be supplied to the control unit 43 only when the threshold value is exceeded. This threshold value TH1 is a value that exceeds when abnormal heating occurs in the motor M1.

  The timer unit 24 measures a time TM1 from when the control unit 43 instructs the motor control unit 26 to start the operation until the operation stop is instructed.

  Here, the operation start instruction is when the control signal of the opening operation or the closing operation is supplied from the control unit 43 to the motor control unit 26, and the operation stop instruction is the control signal of the stop operation from the control unit 43. At the time of supply, supply according to the user operation and the situation where the control unit 43 should stop operation is supplied (for example, supply of a stop signal when the shutter curtain 13 reaches the upper limit or the lower limit, or abnormality detection) The supply of a stop signal based on (1) may be considered.

  The time TM1 measured by the timer unit 24 can be determined according to the specifications of the shutter curtain 13 and the motor M1 and the external environment (for example, the magnitude and temperature of the wind pressure), but is usually within a certain range. Therefore, if the time TM1 is abnormally long, it can be a ground for suspecting the existence of a failure. In addition, a threshold value indicating a normal range can be set in advance, and it can be determined whether it is normal or abnormal by comparing the time TM1 with the threshold value.

  Note that when the control unit 43 determines abnormality and stores the log, the time TM1 measured by the timer unit 24 may be left in association therewith. Thereby, it can contribute to estimation of the cause of abnormal operation. For example, when the closing operation signal is “ON” but the stopping operation signal is “ON” and does not drop (in the case of “abnormal No. 2” in FIG. 7), the closing operation signal is input before the stopping operation signal. Sometimes it is possible to know the time TM1 from the output of the control signal based on the closing operation signal input to the subsequent output of the control signal based on the stop operation signal input, so that the cause of the malfunction corresponding to the stop can be pursued.

  The log storage unit 30 is a non-volatile storage resource for recording a log of an abnormal operation that has occurred in the shutter curtain 13, and is a storage medium (for example, a small memory card (for example, a small memory card) that is mounted in a removable format. SD (Secure Digital) memory card, etc.), or a storage medium fixedly installed in or near the storage processing device 11. In this embodiment, in a removable format. The case where a mounted storage medium is used is shown.

  As described above, by using the storage medium in a removable format, the log storage unit 30 can be removed and the log analysis can be performed by an information processing apparatus (for example, a personal computer) at the time of log analysis. In addition, if a general-purpose storage device corresponding to a predetermined standard, such as an SD memory card, is used, a general-purpose mobile phone or personal computer can be used for storage without preparing a dedicated device. The storage contents stored in the device can be read and log analysis can be executed.

  When using a fixedly installed storage medium, for example, a dedicated reading device or the like is connected to the recording medium through, for example, a connector (not shown), and the storage content stored in the storage medium is read. Log analysis can be performed.

  Various formats can be considered for the storage format in the log storage unit 30. For example, a format in which “abnormality NO.” Determined by the control unit 43 as abnormal is stored in time series in the order in which the abnormality occurred is considered. It is done.

  Although not shown in FIG. 1, for example, if a clock unit that supplies date and time information is provided, the date and time information at the time of occurrence of the abnormality may be stored in association with the abnormality history. Even if the clock unit is not provided, instead of the date and time information, for example, the cumulative number of opening and closing operations of the shutter curtain 13 may be stored in association with the abnormality history.

  The connector unit 29 is a connector for attaching the log storage unit 30 to the storage processing device 11 in a removable format. Depending on the connection format with the log storage unit 30, the connector unit 29 may be a wireless communication interface as long as the log storage unit 30 has a wireless unit and wireless communication is possible.

  The storage management unit 28 creates log information to be stored in the log storage unit 30 in accordance with an instruction from the control unit 43, and corresponds to, for example, an RDBMS (relational database management system). When the storage management unit 28 constitutes an RDBMS, a general RDBMS has a function of executing all operations (addition, deletion, search, etc.) on a relational database. It is sufficient to have a function to add at least a line.

  Since the log is analyzed when an unexpected problem occurs, it is difficult to predict in advance when it will be necessary and when it will be necessary to analyze it retroactively. Therefore, it is desirable to store the contents recorded in the log table TB1 for as long as possible, but the storage capacity of the log storage management unit 30 has a physical upper limit. To continue to record new logs (new lines) after reaching this limit, for example, the oldest line is deleted in order, and the free space created by the deletion is used to create a new line. May be added. In that case, the storage management unit 28 needs to have a function of deleting the oldest row.

(A-1-3) Internal Configuration of Remote Control Transmitter Next, an example of the internal configuration of the remote control transmitter 12 will be described with reference to the functional block diagram of FIG.

  As shown in FIG. 4, the remote control transmitter 12 includes a wireless transmission unit 54, a transmission processing unit 55, a processor 56, a procedure storage unit 57, an operation detection unit 58, and an operation response unit 59. The switches 51 to 53 are provided in the operation detection unit 58.

  The wireless transmission unit 54 wirelessly transmits a wireless signal WL1 generated by performing predetermined wireless processing on the transmission signal received from the transmission processing unit 55, and includes, for example, a transmission antenna system and a filter circuit. ing. The radio signal WL1 may be, for example, a frequency band of about 300 MHz or 400 MHz, for example, and its transmission power may be a weak radio wave of about 1 mW, for example.

  The transmission processing unit 55 receives the transmission processing signal RP from the processor 56, and gives the wireless transmission unit 54 a transmission signal WS generated by performing predetermined encoding processing, modulation processing, and the like.

  Here, since the content of the transmission signal WS is limited to, for example, an operation instruction of the shutter curtain 13 or an ID registration operation, transmission information that can be considered in advance in an information generation source (for example, ROM) of the transmission processing unit 55. It may be prepared so that it can be selected according to the transmission processing signal RP.

  The ID is information for uniquely identifying information from the remote control transmitter 12, and this is necessary because the frequency bands used by other remote control transmitters are the same. It is. On the storage processing device 11 (remote control receiver) side, it is necessary to register one or a plurality of user IDs in advance and authenticate them when they are used.

  The processor 56 controls the function of the remote control transmitter 12, and in particular, receives the determination signal DS from the procedure storage unit 57 and supplies the transmission processing signal RP based on the determination signal ds to the transmission processing unit 55.

  The operation detection unit 58 is provided with operation switches 51 to 53. When the user presses the operation switches 51 to 53, the operation detection unit 58 gives the operation instruction signal PB1 to the procedure storage unit 57, and sends the same operation instruction signal PB2 to the operation response unit 59. It is something to give to.

  Upon receiving the operation instruction signal PB1 from the operation detection unit 58, the procedure storage unit 57 temporarily stores an operation procedure based on the operation instruction signal PB1, and gives the operation procedure to the processor 56. In this case, when a predetermined shutter operation mode is set in advance according to the pressing order and pressing time of the three operation switches 51 to 53 and / or combinations thereof, the input pattern of the operation instruction signal PB1 is stored and the input pattern is stored. The determination signal DS, which is the determination result, can be given to the processor 56.

  The operation response unit 59 outputs a response output RA corresponding to the operation instruction signal PB2 received from the operation detection unit 58. For example, an acoustic generator such as a buzzer, a light emitting element such as an LED (light emitting diode), or the like. Applicable.

(A-2) Operation of Embodiment Next, an operation of a process of storing a log when there is an input that restricts the operation of the shutter curtain 13 in the storage processing device 11 of the present embodiment will be described with reference to the drawings. .

  First, at the time of installing or closing the electric switching system, the log storage unit 30 does not store a log, and the control unit 43 monitors the presence or absence of signal input from the peripheral device (step 101).

  That is, the control unit 43 monitors the presence / absence of signal input from the fixed operation unit 14, the reception processing unit 42, the comparison unit 22, the temperature sensor unit 27, and the timer unit 24.

  At this time, when the “open signal” is given from the fixed operation unit 14 or the reception processing unit 42, the control unit 43 detects that the “open signal” is “ON”, and when the “close signal” is given. When the “close signal” is detected as “ON” and the “stop signal” is given, it is detected that the “stop signal” is “ON”. Note that when the “open signal”, “close signal”, and “stop signal” are not given, the control unit 43 sets each signal to “OFF”.

  When the shutter curtain lower end portion 13A has reached the upper limit position or more, the control unit 43 receives the “upper limit signal” from the comparison unit 22, detects that the “upper limit signal” is “ON”, and then releases the shutter. When the curtain lower end 13A has reached the lower limit position or less, the control unit 43 receives the “lower limit signal” from the comparison unit 22 and detects that the “lower limit signal” is “ON”. The control unit 43 sets each signal to “OFF” when the “upper limit signal” and the “lower limit signal” are not given.

  Further, when an obstacle is detected, the control unit 43 receives an “obstacle detection signal” from the infrared receiving unit 25, detects that the “obstacle detection signal” is “ON”, and provides an “obstacle detection signal”. If not, the “obstacle detection signal” is set to “OFF”.

  Thereafter, when a signal DS or RP for instructing the opening / closing operation of the shutter curtain 13 is given to the control unit 43 from the fixed operation unit 14 or the reception processing unit 42 (step 102), the control unit 43 receives the input signal at that time. It is determined whether or not the input state matches the input signal combination pattern defined in the abnormality determination table 43B (step 103).

  When the control unit 43 determines that the input state of the input signal does not match the input combination pattern, the control unit 43 performs normal control processing, and the input signal combination information at this time is not stored, and after the normal control processing Returns to the monitoring state of the input signal.

  That is, the control unit 43 gives a control signal according to the operation instruction signal to the motor control unit 26. When a control signal is given to the motor control unit 26, the motor control unit 26 drives and controls the motor M1 according to the control signal, and opens and closes the shutter curtain 13.

  On the other hand, when the control unit 43 determines that the input state of the input signal matches the input combination pattern, the control unit 43 determines that the operation is a predetermined abnormal operation, and the combination information of the input signals at the time of the abnormal operation is stored ( Step 104).

  For example, a case where the user U1 instructs the closing operation of the shutter curtain 13 from a state where the shutter curtain lower end portion 13A is at or above the upper limit position (for example, a fully opened state) will be described as an example.

  In this case, since the shutter curtain lower end portion 13A has reached the upper limit position, the “upper limit signal” is given from the comparison unit 22 to the control unit 43, the “upper limit signal” is “ON”, and the “lower limit signal” is “OFF”.

  Then, when the user U1 operates the switch for closing the fixed operation unit 14 or the remote control transmitter 12, a “close signal” is given to the control unit 43 from the fixed operation unit 14 or the reception processing unit 42. At this time, since the “close signal” is given to the control unit 43, the “close signal” is “ON”, and the “open signal” and the “stop signal” are “OFF”.

  While receiving an operation instruction signal based on the operation instruction of the user U1, when an obstacle is detected and the obstacle detection signal is given from the infrared receiving unit 25 to the control unit 43, the “obstacle detection signal” is set to “ON”. "

  Then, the input status of the input signal at this time is “upper limit signal: ON”, “lower limit signal: OFF”, “open signal: OFF”, “close signal: ON”, “stop signal: OFF”, “ Since the obstacle detection signal is “ON”, which corresponds to the combination pattern of “abnormality No. 1” in the abnormality determination table 43B of FIG. 7, the operation instruction of the shutter curtain 13 by the user U1 is canceled, and the control unit 43 It is determined that the operation is abnormal in response to the operation instruction.

  Then, the control unit 43 sets the abnormality NO. In the abnormality determination table as the input combination information defined in “Abnormality No. 1”. "1" is given to the storage management unit 28, and "1" is stored in the log storage unit 30 in accordance with a predetermined storage management method. As the storage management method, for example, a method for storing log information that has been subjected to processing such as encryption or symbolization may be adopted.

  Thereafter, similarly, when there is an abnormal operation that restricts the opening / closing operation in response to an operation instruction from the user, the control unit 43 stores the input combination information at that time as a log.

  Thereafter, the maintenance person can read the storage content (log information) stored in the log storage unit 30 by a predetermined method, perform a predetermined log analysis, pursue the cause of the malfunction, and perform appropriate maintenance.

  The log analysis method depends on the format of the log storage unit 30, but when a removable storage medium (for example, an SD card) is used as in this embodiment, the log storage unit 30 is connected to the connector unit. For example, a notebook personal computer or a mobile phone can be used. The contents read from the log storage unit 30 may be displayed on the screen of a notebook personal computer or mobile phone, and the log may be analyzed based on the knowledge and experience of the maintenance person. If is used, there is a high possibility that more efficient log analysis can be performed. Also, when using the communication function of a mobile phone or a notebook computer, for example, the read log information is transmitted from the notebook computer or mobile phone to a predetermined server, and the log analysis processing is performed on the server side. It may be performed by. In this case, the analysis result and the content of appropriate maintenance to be performed according to the analysis result can be transmitted from the server to the notebook computer or mobile phone.

(A-3) Effect of Embodiment As described above, according to the present embodiment, in order to determine that the input information that invalidates (cancels) the operation instructed by the user and restricts the instruction operation is abnormal. By providing the prepared abnormality determination table 43B and storing the input combination information defined in the abnormality determination table 43B as a history, the cause of the failure can be estimated based on the history information during subsequent maintenance work. Therefore, maintainability can be improved.

(B) Other Embodiments (B-1) In the above-described embodiment, the control unit 43 is described as storing the input combination information of the abnormality determination table 43B as a history. The case of “NO.” Was explained. However, the present invention is not limited to this, and information other than numbers (for example, characters, symbols, etc.) may be used, or the input status of the input signal itself (for example, “ON / OFF” information) may be stored.

  Further, the control unit 43 may store not only the prescribed input combination information in the abnormality determination table 43B but also the input state of the input signal when an operation for restricting other user operation instructions is performed.

  Further, the content of the control signal instructed by the control unit 43 after performing an operation for restricting the operation instruction (occurrence of some trouble (including abnormality)) may be stored in association with the log history. Thereby, input information and output information can be stored in association with each other, and maintainability can be further improved.

  Furthermore, for example, even when an abnormality is detected by the temperature sensor unit 27 or an emergency detection means (emergency) (not shown), the abnormality detection related information in that case may be stored as a history. In this case, it is desirable to store the history in a format that distinguishes it from the log based on the abnormality determination table 43B. In this case, it is preferable that the log information is used in a time-series manner.

(B-2) In the above-described embodiment, the case where the present invention is applied to a system using a dedicated wireless remote control system and a wired remote control system has been described. However, the present invention may be applied to any one of the respective remote control systems.

  Moreover, the remote control transmitter 12 may be mounted on a predetermined mounting portion or the like, and may be applied as a wired remote control system such as when the fixed operation unit 14 is used.

  In the above-described embodiment, the wireless 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. However, the application range of the frequency band, the transmission power, and the like is limited to this. It is not something. 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.

(B-3) In the embodiment described above, the fact that the shutter curtain lower end portion 13A is in contact with the object is transmitted to the storage processing device 11 using infrared rays. However, the infrared rays are replaced with other transmission signals. Is possible. For example, it may be replaced with another type of optical signal such as a laser beam, or may be replaced with a transmission signal other than the optical signal such as an electric signal or an ultrasonic signal. If necessary, this transmission signal may be transmitted using a wired transmission path (for example, an optical fiber cable or a twisted pair cable) instead of a wireless transmission path.

  In addition to information on whether or not the shutter curtain lower end 13A is in contact with an object, for example, information on the presence or absence of power supply abnormality (for example, battery abnormality) for the infrared port to output infrared IRD is included in the transmission signal. This information may also be included in the input combination pattern. In this case, information such as power supply abnormality can be notified to the control unit 43 by a transmission method other than infrared (for example, wired communication or other wireless communication), and the information is included in the input combination pattern. Also good.

(B-4) Regardless of the embodiment described above, load sensing based on torque fluctuations of the motor is performed for emergency detection (for emergency) and / or for detecting contact of an object with the shutter curtain lower end (corresponding to 13A). You may do it. In load sensing, the magnitude of torque is monitored, and a load larger than normal is sensed by detecting that the torque has greatly fluctuated. A larger load than usual occurs, for example, when the lower end of the shutter curtain (corresponding to 13A) that closes contacts the floor surface FL or an obstacle.

  Therefore, when a large change in torque is detected, the motor output shaft can be stopped to stop the shutter closing operation, or the motor output shaft can be reversed to start the opening operation. When performing load sensing based on such torque fluctuation, it is also desirable to be able to change a predetermined threshold value for determining whether or not torque fluctuation is large.

(B-5) In the above-described embodiment, the storage processing device 11 is arranged outside the fixed operation unit 14, but all or some of the components of the storage processing device 11 are arranged in the fixed operation unit 14. Of course, you may.

(B-6) In the above-described embodiment, the position of the shutter curtain lower end portion 13A is logically detected using the encoder pulse, but the present invention is not necessarily limited to this.

  For example, the load applied to the motor M1 is detected (for example, a change in the rotation amount is inspected using a tachometer or the like, and the position of the shutter curtain lower end portion 13A is detected based on the inspection result). It is also possible to provide a tape switch on the guide rail GR and provide a protrusion mechanism in the shutter curtain lower end 13A that protrudes and presses the tape switch when an object comes into contact with the shutter curtain lower end 13A. is there.

(B-7) Regardless of the embodiment described above, the present invention always mechanically urges the shutter in the closing direction, such as a disaster prevention shutter, by a shutter or a spring of the type that performs the closing operation with its own weight. It can also be applied to the types of shutters. Even in these types of shutters, since the opening operation is performed electrically, when the shutter curtain lower end (corresponding to 13A) is in contact with an object, it can be reversed and raised electrically. .

(B-8) Furthermore, regardless of the above-described embodiment, the shutter curtain 13 may move in a direction other than the vertical direction. The present invention is also applicable to, for example, a shutter that slides in an oblique direction or a horizontal direction.

  Furthermore, 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 a direction in which an opening is opened, such as winding, contraction, slide movement, folding, and the like when the opening exists.

  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 respond to changes in pressure, temperature, static electricity, incident light, and the like can also be applied.

(B-9) In the storage processing apparatus 11 of the above embodiment, it is natural that the control unit 43 can have the functions of the components shown outside the control unit 43. For example, the control unit 43 itself can have functions corresponding to the counter unit 23, the comparison unit 22, the timer unit 24, the storage management unit 29, and the like. In this case, for example, the signal S22 supplied from the comparison unit 22 to the control unit 43 is generated inside the control unit 43, but is input to the control unit 43 when it is generated inside the control unit 43. It can be processed as a thing.

(B-10) Regardless of the above embodiment, a monitoring processor may be provided in the storage processing device 11 separately from the control unit 43. In this case, an input to the control unit 43 and an output from the control unit 43 are monitored by the monitoring processor, and the monitoring processor instructs the storage management unit 28 to add a row according to the monitoring result. It may be.

  Furthermore, the control unit 43 and the monitoring processor may monitor the normality of the operation, and the monitoring result may be recorded in the log storage unit 30 as a log.

  The cause of the problem with low reproducibility is not limited to the possibility of the controller 43 itself, which is one of the components having the most complicated functions, in the entire remote control system. Monitoring the normality of itself greatly contributes to the improvement of maintainability.

(B-11) Moreover, when measuring the voltage level of each part in the storage processing apparatus 11 or its periphery, it is good to prepare the data item for recording the measurement result. Further, when there may be a plurality of legitimate user remote control transmitters that can wirelessly transmit to the storage processing device 11, each remote controller that is accommodated in the wireless signal WL1 and delivered to the storage processing device 11 is provided. A data item for recording the ID of the transmitter may be prepared. Furthermore, a data item for recording a monitoring result related to the magnitude of the torque described above may be prepared. Also, a data item for recording the date and time when the operation or a predetermined special operation was performed, a data item for recording the number of operations per predetermined unit time (for example, one hour), and an operation speed are recorded. Operation-related data items such as data items for this purpose may be prepared as necessary.

(B-12) In the above-described embodiment, it has been described that all input combination operations when it is determined as an abnormal operation after the operation of the switching system is started are stored as a history. The user U1 or the maintenance person may be able to specify.

  For example, when a problem with low reproducibility occurs first, if a maintenance person or the like designates the storage processing device 11 to start recording a log, the problem with low reproducibility occurs again. Sometimes enough logs are likely to be obtained. Such a configuration also contributes to saving of the storage capacity of the log storage unit 30.

  In addition to this, a predetermined condition (additional condition) may be set, and a line may be added to the log only when this additional condition is met.

  In addition, the control unit 43 and the monitoring processor can be provided with a function that can determine the normality of the operation relating to each component in and around the storage processing device 11. In that case, it is also possible to add only the row relating to the shutter operation that is determined to be not normal to the log table TB1.

  Further, the separation between the log information for each time may not be a line feed, and other methods can be used as long as it can be recognized that it is one log information. For example, the number of bits of log information data for each time may be determined in advance. For example, information (for example, a symbol, a character, etc.) indicating that the log information is separated after one piece of log information is input. Is added after the log information.

  Note that log information of several times may be collected (for example, a few digits), and the corresponding barcode may be displayed during maintenance. In addition, the storage device that stores the log information may cooperate with an output device that prints on roll paper or the like, and may output the information on roll paper or the like each time the log information is stored.

(B-13) Further, in the above embodiment, the relational database is used. However, in the present invention, there is a possibility that another type of database can be used.

  In the above-described embodiment, one log storage unit 30 is attached to one storage processing device 11, and the correspondence between the storage treatment device and the log storage unit is 1: 1, but this correspondence is not necessarily 1: 1. It doesn't have to be.

  For example, one storage processing device may be configured to control the operation of a plurality of shutters by controlling a plurality of motors (for example, the M1). In that case, the log storage unit 30 is set to each shutter. You may make it prepare for every.

(B-14) Further, when the log storage unit 30 is realized as a memory card, a warning message is output when the free capacity is equal to or less than a predetermined threshold capacity, You may be prompted to replace the memory card.

(B-15) It should be noted that the effects of the present invention can be obtained even if some of the components of the above embodiment are omitted or replaced with components having other functions.

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

  Furthermore, the present invention is not only used for a shutter, but also for other opening / closing devices such as doors, windows, overhead doors, roll screens (for example, light-shielding curtains), blinds, awning devices, and some or all mixing systems thereof. It is possible to apply.

  Although the present invention has been realized mainly by hardware in the above description, the present invention can also be realized by software.
