Description

  The present invention relates to a history information recording device for a shutter device.

  Since the shutter device is fixed to a building or the like, even if an abnormality occurs, it is difficult to collect and examine it, and it is difficult to acquire data related to the occurrence of the abnormality. In addition, since it is desirable to perform maintenance according to each usage pattern when performing maintenance on the shutter device, it is desirable to acquire data that indicates the usage status.

  Therefore, in the prior art, an apparatus for knowing what kind of abnormality / failure has occurred in the past by storing data on the number of times of opening and closing the shutter and time data and abnormality data relating to abnormality that has occurred in the past (Patent Document 1), An apparatus capable of storing the abnormal data generated in the shutter and the operation at the time of occurrence for the past 10 times as a set (Patent Document 2). With the improved technology of Document 1, the abnormal data and the number of times of opening and closing are set. The device that can know when and what kind of abnormality has occurred (Patent Document 3), and the automatic door technology, the history of the number of times the door is opened and closed, the number of maintenance times, etc. An apparatus (Patent Document 4) that can be stored periodically is disclosed.

  As described above, by the techniques of Patent Documents 1 to 4, it is possible to know “when and what abnormality has occurred” in the past. It is also possible to obtain information on how many times the shutter has been used. From the above, it is considered that this is a very useful technique for obtaining information for maintenance.

Japanese Patent Laid-Open No. 11-16014 JP 2002-295150 A JP 2005-76269 A JP 2003-91756 A

  However, the devices of Patent Documents 1 to 4 lack information to analyze the true cause of the abnormality. That is, there are cases where the cause of the occurrence of the abnormality cannot be clearly understood only by such information. For this reason, it is difficult to analyze the failure by ascertaining “because it really broke down”, “because a sudden environmental change occurred”, “because the software misdetected”, or “the user used it unexpectedly”. In particular, it is not known that there were environmental conditions and usage conditions that were not anticipated by the designer.

  Therefore, it may be possible to interview the user directly when an abnormality occurs or during maintenance, but even users who are actually using the system may not be able to convey the usage mode without being over and under and sufficient information can be obtained. It wasn't limited.

  The present invention has been completed in view of the above circumstances, and an object to be solved is to provide a history information recording device for a shutter device capable of recording history information in the shutter device in a more desirable form.

Accordingly, since history information required later can be generated according to the type of trigger, maintenance that will be performed later, investigation of the cause of a defect, and the like can be effectively performed.

Appropriate history information can be stored by adopting the following configuration (2) or (3) with respect to the configuration (1) described above.

For example, history information to be saved by a trigger related to the occurrence of an abnormality (abnormality detection trigger) as the type of trigger when the operation time reaches a predetermined amount (when a certain time has passed: The history information that was saved by the trigger of cumulative information trigger) is preferentially saved (when history information cannot be recorded any more in the history information recording unit, the history information saved over time is replaced. Such). On the contrary, the history information saved by the cumulative information trigger is not saved until the history information saved by the abnormality detection trigger is replaced. However, it is desirable to secure an area where one or more history information stored by the cumulative information trigger can be recorded.

The history information recording unit can record a plurality of the history information,
In the history information recording unit, a region for recording the history information is limited to a part by the cumulative information trigger.

  In this configuration, the history information recording unit stores the history information by the cumulative information trigger by restricting the history information by the cumulative information trigger to a part of the area for storing the history information by the cumulative information trigger. Everything is not overwritten.

For each of the combinations (1), (1) and (2) and (1) and (3) described above, the following configurations (4) and / or (5) can be employed.

It is a flowchart which shows the recording method of the historical information to the historical information recording part of the historical information recording device of the shutter apparatus of this embodiment.

  The history information recording device of the shutter device of the present invention will be described in detail below based on the embodiment.

(Constitution)
The history information recording device of the shutter device of the present embodiment is a device that is used together with the shutter device shown in FIG. 1 and records the operating state of the shutter device. The shutter device to which the history information recording device of the shutter device of this embodiment is applied is installed so as to open and close an opening of a structure such as a building as shown in FIG. The shutter apparatus installed in a structure is shown typically. The shutter device includes a shutter device body 1, a winding device 2 that opens and closes the shutter device body 1, a drive control device 3 that drives the winding device 2, and an operation panel 4 that outputs a control signal to the drive control device 3. And have.

  The shutter device main body 1 has a shutter curtain 12 and a pair of vertical struts 11 that support the shutter curtain 12 from both sides in the width direction so that the shutter curtain 12 can move in the vertical direction and restrict movement in the front and back directions. The shutter curtain 12 can open and close the opening of the building by a length H in the height direction. The shutter curtain 12 is disposed so that a slat can be opened and closed. The operation panel 4 includes operation switches 4a to 4e for performing operations such as opening and closing of the shutter curtain 12 and opening and closing of the slats of the shutter device body 1, and the operation state of these operation switches 4a to 4e is an operation signal as the drive control device 3 ( It is output to the operation switch recognition unit 35).

  As shown in FIG. 2, the winding device 2 includes a motor 21 for winding the shutter curtain 12, a speed reducer 22 for reducing the output of the motor 21, a winding shaft 23 for winding the shutter curtain 12, An encoder 24 that measures the rotation of the motor 21 and detects the winding state of the shutter curtain 12 is provided.

  As illustrated in FIG. 2, the drive control device 3 includes a microcomputer (operation data generation unit) 31, a history information recording unit 32, a detection unit (33 to 37), and an information readout terminal 38. The microcomputer 31 receives state data detected by the detection units (33 to 37), and controls the shutter device based on the state data. Control of the shutter device by the microcomputer 31 can be performed based on the state transition diagram. As a state transition diagram relating to the opening and closing of the shutter curtain 12, a table as shown in FIG. 3 can be used. The shutter device is assumed to be in one of the operating states described in the upper column. Further, it is assumed that each event described in the left column occurs in the shutter device. A response to each event (what kind of operating state is changed by the event) is determined according to the operating state of the shutter device. For example, when the open state (operation switch 4a) is pressed when the operation state is "halfway stop (the shutter curtain 12 is stopped halfway between the fully closed state and the fully open state)", "3" from the table is displayed. Transition to the operating state (opening operation). Similarly, in each operating state, an operating state that transitions next in response to each event is defined. In the state transition diagram, “-” is indicated when such an event is not considered to occur or when there is no need to change the operating state even if such an event occurs. This means that no transition of the operating state occurs.

  A work memory (device information recording unit) 311 is provided in the microcomputer 31. The detection units (33 to 37) include a motor current detection unit 33, an encoder pulse detection unit 34, an operation switch recognition unit 35, a power supply voltage detection unit 36, and a temperature detection unit 37. Information detected by each detection unit (33 to 37) as a corresponding state in the shutter device is input to the microcomputer 31 from each detection unit.

  The motor current detector 33 detects the current flowing through the motor 21 and detects the torque of the motor 21 from the detected current. The encoder pulse detector 34 detects the encoder pulse from the encoder 24 and detects the position (open / closed state) of the shutter curtain 12 in the opening / closing direction. The operation switch recognition unit 35 receives the type of the operated switch from the operation switch. The power supply voltage detector 36 detects a power supply voltage. Each temperature measured by the temperature detection unit 37 is input from a motor temperature sensor 371 that measures the temperature of the motor 21 and an atmosphere temperature sensor 372 that measures the temperature of the atmosphere in which the shutter device is installed.

  The microcomputer 31 generates the device information obtained by processing the state data as it is and / or processing the state data detected by each detection unit, and stores the device information in the device information recording unit 311 including a volatile memory in the microcomputer 31. The frequency of recording in the device information recording unit 311 is not particularly limited, but can be performed every predetermined time, or can be performed in accordance with the generation of a trigger described later.

  As device information, information relating to the operation of the shutter device (number of times the shutter curtain 12 has been fully opened: number of times of full opening, number of times of full closing: number of times of full closing, number of times of stopping halfway: number of times of stopping) Information (number of operations of the operation switches 4a to 4e. Number of times the shutter curtain 12 is forcibly operated: it can be detected when a pulse is generated from the encoder 24 without driving the motor 21. Other special operations such as setting operations. Number of times: Specifically, operations that are not normally performed by the user, such as operations that are performed during installation or maintenance, such as lower limit position setting, load sensitivity setting, correction setting, reset operation, etc. of the shutter curtain 12 Information on environment (temperature information: maximum temperature / minimum temperature, power supply voltage information: maximum voltage / minimum) Pressure, output current value to the motor 21, total energization time), information on occurrence of abnormality (the number of occurrences of pinching: the current of the motor 21 detected by the motor current detector 33 when the motor 21 is driven exceeds the threshold value) The number of occurrences of motor lock, the number of occurrences of motor lock: supply of overcurrent to the motor 21 (current exceeding a threshold larger than the detection of the number of occurrences of pinching), the number of operation of the temperature protector: the temperature of the motor 21 falls within a predetermined range The number of misses) can be exemplified. In addition, the state data processing method for generating device information is not particularly limited, but can be encoded or averaged for a plurality of state data in order to save the data amount. Further, the number of operations of the shutter curtain 12 and the number of times each of the switches of the operation panel 4 are operated may be combined with the time data so as to add frequency information. As device information to be recorded in the device information recording unit 311, in addition to the state data itself, the time related to the acquisition of the state data (time when the state data was acquired, data acquisition when processed to the average / number of times, etc. is performed. It is desirable to record the period of time. If the device information is recorded periodically, the time when the status data is acquired may be known without recording the time information. The device information recording unit 311 is a temporary storage device that also includes a work memory for the microcomputer 31. When the power of the microcomputer 31 is turned off (the microcomputer 31 is not energized), the stored information disappears.

  Since the capacity of the device information recording unit 311 is limited, only the latest device information can be recorded. Further, when a plurality of pieces of device information are recorded, when the capacity becomes full, old pieces of device information recorded in the device information recording unit 311 can be replaced. Furthermore, the order of replacement may be changed according to the type of device information and the type of trigger for recording device information.

  For example, it is possible to set a high rank for important information among a plurality of pieces of apparatus information and replace the apparatus information recorded in the apparatus information recording unit 311 according to the rank. Among the device information, information related to the occurrence of a defect, information related to a remarkably large number of repetitions when the same operation is repeatedly performed, and the like are set in a high order. Further, it is desirable to save several pieces of data from the oldest even if the device information has a lower rank.

  For example, replacement of device information can be performed sequentially for device information of the same order or lower in order from the oldest, or can be repeatedly performed every other order (older device information is retained to some extent by replacing every other device information) be able to).

  The history information recording unit 32 is a non-volatile memory composed of an EEPROM or the like, and the device information read from the device information recording unit 311 when the trigger is generated is in the same state and / or processed state. History information that is data is recorded. The device information read from the device information recording unit 311 to generate history information varies depending on the type of trigger. Details will be given at the time of and after the description of the trigger type. As history information, it is desirable to include time information in addition to the type of trigger.

  The history information recording unit 32 may also store a logic (program) for operating the microcomputer 31. The history information is recorded in the history information recording unit 32. When a preset trigger exists (occurs) in the device information, the device information is read from the device information recording unit according to the type of trigger and the history information is recorded. Generated and recorded in the history information recording unit 32. The data format of the history information recorded in the history information recording unit 32 can be a fixed predetermined data length (null data or the like is added to a portion where no data exists). The data management of the history information recording unit 32 is facilitated by fixing the data length of the history information. Similarly, the data format of the device information recorded in the device information recording unit 311 can be a fixed length. Also, a lot of device information can be recorded for new history information, and less device information can be recorded for old history information than for new history information.

  As a trigger, an event can be selected which is useful when the state data at that time is used to reproduce the state of the shutter device later. The following can be illustrated as a trigger. The description in parentheses is an example of history information to be recorded. In addition to the history information, it is desirable that the latest state transition (for example, state transition for two times) of the shutter device is the history information.

  (1) Cumulative information trigger: every elapse of a certain time of operation time (time since power-on, cumulative energization time so far, time for actually driving the motor 21 that drives the shutter curtain 12), This trigger is generated periodically when the operation is continued, such as every predetermined number of operations and every predetermined number of acquisition / recording times of device information. The history information generated by this trigger includes information related to the number of operations of the operation switches 4a to 4e, information related to the number of times the shutter curtain 12 and slats are opened and closed, temperature / atmosphere temperature of the motor 21, and fluctuations in the power supply voltage.

  (2) Abnormality detection trigger: Generated when an abnormality occurs in the shutter device, when the state data detected by the detection unit (33 to 37) falls within a preset abnormal value range. It is a generated trigger. For example, the motor current detection unit 33 detects an abnormality (such as an overcurrent) in the current supply to the motor 21 (something is caught in the shutter curtain 12 or the motor 21 and the motor 21 cannot rotate). In this case, the device information used to create the history information includes the current value, the position of the shutter curtain 12, the operating state of the operation switches 4a to 4e, the temperature of the motor 21), and the motor 21. Although it is not driven, the encoder pulse detector 34 detects a pulse from the encoder 24 (used to create history information in this case where it is suspected that the user manually opened and closed the shutter curtain 12). The apparatus information includes the position of the shutter curtain 12, the cumulative number of events, etc.), the encoder pulse detector 3 Detected by the pulse from the encoder 24 detected by the encoder 24 during the opening and closing of the shutter curtain 12 (the device information used to create the history information in this case is suspected of a special usage mode is the position of the shutter curtain 12 The cumulative number of events, the temperature of the motor 21, the motor current, etc.), and the operation of the operation switches 4a to 4e detected by the operation switch recognition unit 35 exceeds the preset frequency and operation time. (The device information used to create the history information in this case where the failure of the operation switches 4a to 4e is suspected in a special usage mode includes the cumulative number of this event, the type of the operated operation switches 4a to 4e, and Each type), and the power supply voltage detector 36 has detected fluctuations in the power supply voltage (voltage fluctuation, instantaneous power failure, harmonics, etc.) The device information used to create history information in this case is suspected to be the cumulative number of events, etc.), and the ambient temperature / motor 21 temperature detected by the temperature detector 37 has exceeded a predetermined range. (The device information used to create history information in this case where abnormality of the motor 21 or environmental change is suspected includes the temperature of the motor 21, the ambient temperature, the cumulative number of events, and the number of operations of the operation switches 4a to 4e.・ Frequency, etc.) When an abnormality detection trigger is generated, some sort of notification device (for example, an LED, a lamp, or a liquid crystal provided on the operation panel 4 can be lit, or a device that emits sound can be provided on the drive control device 3 or the operation panel 4). Can do.

  Similar to the device information recording unit 311, the history information recording unit 32 has a limited capacity. When the capacity is full, the history information recording unit 32 can be replaced with the oldest recorded history information. . Furthermore, the order of replacement may be changed depending on the type of history information and the type of trigger.

  For example, it is possible to set a high ranking for important information among a plurality of history information and replace the history information recorded in the history information recording unit 32 according to the ranking. Among the history information, information recorded by the abnormality detection trigger (related to the occurrence of a defect) is set in a high order. Further, even if the history information is of lower rank, some data from the oldest can be saved.

  For example, replacement of history information can be performed sequentially from the oldest to the history information below the same rank, or it can be repeated several times in the oldest order (retaining some history information to some extent by replacing every other place) be able to).

  The information reading terminal 38 is an interface through which the device information recorded in the device information recording unit 311 and the history information recorded in the history information recording unit 32 can be read through the microcomputer 31. Even if the terminal 38 is not provided, it is possible to extract the history information by removing the history information recording unit 32 from the drive control device 3 and analyzing it.

(Operation)
Normal Operation An operation assumed to be normally performed in the shutter device of the present embodiment will be described based on a state transition diagram. The operating state of the shutter device is as follows: 0: the position of the shutter curtain 12 is stopped between fully closed and fully open (intermediate stop), 1: the position of the shutter curtain 12 is completely closed and stopped. (Fully closed stop), 2: when the shutter curtain 12 is fully opened and stopped (fully opened stop), 3: when the shutter curtain 12 is moving in the opening direction (opening operation), 4: shutter There are five cases where the curtain 12 is moving in the closing direction (closing operation), and transitions between these operating states based on the occurrence of an event.

  As events, A: operation of the open switch 4a (open SW), B: operation of the stop switch 4b (stop SW), C: operation of the close switch 4c (closed SW), D: shutter by pulse input from the encoder 24 When it is detected that the position of the curtain 12 is fully opened (fully opened detection), E: When it is detected that the position of the shutter curtain 12 is fully closed by pulse input from the encoder 24 (fully closed detection), F: Six cases in which the position of the shutter curtain 12 does not change even when power is supplied to the motor 21 (no pulse input from the encoder 24) (pinch detection).

  If there is an “open SW” in the “intermediate stop”, the transition is made to the “open operation”, if there is a “stop SW”, the “intermediate stop” is maintained as it is, and if there is a “closed SW”, the transition is made to the “close operation”. To do. If there is an “open SW” in the “fully closed stop”, a transition is made to an “open operation”, and if there is a “stop SW”, the “fully closed stop” is maintained as it is. If there is “stop SW” in “full open stop”, it is maintained as “fully open stop” as it is, and if there is “closed SW”, it is shifted to “closed operation”. If there is an “open SW” in the “open operation”, the “open operation” is maintained as it is. If there is a “stop SW”, the transition is made to “stop halfway”, and if there is a “closed SW”, the transition is made to “closed operation”. If there is a “detection”, the transition is made to “full open stop”. When “Closed operation” is “Open SW”, transition is made to “Open operation”, “Stop SW” is transitioned to “Intermediate stop”, and “Closed SW” is maintained as “Closed operation”. When there is “closed detection”, the state transitions to “fully closed stop”, and when there is “pinch detection”, the state transitions to “open operation”. An event not specified here is treated as an event that cannot occur in each operating state, and if such an event occurs, it can be treated as one of the “abnormality detection triggers” as an abnormality occurrence. .

・ Recording of device information and history information during normal operation When no occurrence of abnormality is detected, every time a predetermined condition is satisfied (for example, when a certain time elapses, one of the operation switches 4a to 4e is operated). If the maximum value of the current value supplied to the motor 21 is updated, or if the maximum value or the minimum value of the ambient temperature is updated, the device status data is acquired, and the device information ( Cumulative information) is generated and recorded in the device information recording unit 311. The device information to be recorded includes the number of times counted from a certain reference time (for example, when the power is turned on or when the shutter device is started), the maximum / minimum value, and the operation information (the number of fully open stops, the number of fully closed stops, and the midway stop) Frequency), operation information (open switch 4a operation count, stop switch 4b operation count, close switch 4c operation count, forced open operation count, forced close operation count), environment information (maximum temperature) , Minimum temperature, maximum power supply voltage, minimum power supply voltage, motor output voltage, total elapsed time) and abnormality information (number of pinching occurrences, number of motor lock occurrences, number of temperature protector operations). It is also desirable to calculate the cumulative number with reference to the history information recorded immediately before. For example, when the device information recorded in the device information recording unit 311 is lost due to a power failure or the like, the device information can be generated by restoring information such as the cumulative number based on the remaining history information.

  Then, a condition (cumulative information trigger: for example, every hour elapsed) that elapses longer than the predetermined condition is set, and when the condition is satisfied, the apparatus information is read from the apparatus information recording unit 311 to generate history information. And recorded in the history information recording unit 32. The history information recorded in the history information recording unit 32 by the cumulative information trigger can record a plurality of history information including old ones, but can be rewritten with the latest one as shown in FIG. FIG. 4 shows a data structure of history information in the history information recording unit 32. The history information recording unit 32 includes a combination of the latest information (one) and past histories (a plurality of sets). Since the latest information is considered important, device information that can be obtained is recorded as much as possible. As for the past history, as many abnormality occurrences as possible are recorded so as to record the minimum necessary apparatus information for recording the occurrence frequency of the abnormality. The history information recording unit 32 is added with a checksum for error detection.

・ Recording of operation and history information at the time of occurrence of abnormality Whether or not an abnormality has occurred is determined based on a threshold set for each detection unit (33 to 37) and when the threshold is exceeded (an abnormality detection trigger), it is determined that an abnormality has occurred. it can. The type of abnormality assumed to occur is different for each of the detection units (33 to 37), and the device information (status data) necessary for analyzing the abnormality is different. Accordingly, necessary information is extracted from the latest apparatus information according to the type of abnormality detection trigger (the type of abnormality that has occurred), and history information relating to the occurrence of the abnormality is generated and recorded in the history information recording unit 32. Examples of information to be extracted include those described above. The size of the history information has a fixed data length from the viewpoint of easy recording.

  Furthermore, since information on the state transition of the apparatus is also important when an abnormality occurs, a plurality of state transitions (for example, three state transitions) that have occurred until the abnormality occurs are recorded in the history information. The history information recorded by the abnormality detection trigger is recorded in an area different from the area recorded by the normal cumulative information trigger. Then, a plurality of sets of history information generated by the abnormality detection trigger are recorded from the latest one (10 sets in the embodiment, the oldest history information is replaced by the latest history information). Note that the same information as the history information recorded by the cumulative information trigger is recorded in the same area of the history information recording unit 32 by the abnormality detection trigger. In other words, the history information recorded by the abnormality detection trigger has a higher rank than the history information recorded by the cumulative information trigger in normal times. Therefore, all collected history information is recorded for the latest abnormality occurrence.

・ Summary As described above, this apparatus records history information according to the flowchart shown in FIG. First, it is determined whether or not an abnormality detection trigger has occurred (S1). If no abnormality detection trigger has occurred, it is determined whether or not a cumulative information trigger has occurred (S2). When no cumulative information trigger occurs, recording to the history information recording unit 32 is not performed.

  When it is determined in S2 that a cumulative information trigger has occurred, history information is generated from the device information recorded in the device information recording unit 311 and the latest information in the history information recording unit 32 is recorded (accumulated information trigger). The history information is recorded in a region where history information is recorded due to the occurrence of (S4).

  When it is determined in S1 that an abnormality detection trigger has occurred, history information is generated from the device information recorded in the device information recording unit 311 and a past history is recorded in the history information recording unit 32 (an abnormality detection trigger) The history information generated according to the type of the abnormality detection trigger is recorded in the area in which history information is recorded due to the occurrence of (S3). If there is no free space in the past history recording area, the oldest information is sequentially replaced (S3). Then, the same process as S4 mentioned above is performed, and apparatus information is recorded on the area | region which records the newest information (S4).

・ Reading of history information When the user of the shutter device senses the occurrence of an abnormality, a service person who is contacted through a service center or the like visits the site where the shutter device is used, and the history information recorded in the history information recording unit 32 is possible. If so, it is possible to identify the cause of the abnormality by reading and analyzing the recorded information recorded in the device information recording unit 311 to help resolve the abnormality. Even if a power supply abnormality or the like occurs, the history information recorded in the history information recording unit 32, which is a nonvolatile memory, can be read out and can be used for analysis of the abnormality. In addition, information regarding the use of the shutter device can be obtained even during periodic inspections. It can be used for maintenance and further device development.

  As described above, when an abnormality occurs in the shutter device or in periodic inspection, it is possible to obtain necessary information regardless of the user's attention point when collecting information on the state of the shutter device. Services can be provided.

・ Others In the above description, the shutter curtain was opened and closed. However, the shutter curtain can be opened and closed as a blind by rotating the slats constituting the shutter curtain, or can be opened and closed by expanding and contracting the slats (for example, an operation panel). The operation switches 4d and 4e can be opened and closed.
