Description

  The present invention relates to an automatic door monitoring system that monitors the state of an automatic door.

  As a conventional automatic door monitoring system, if the door closed signal remains ON for a certain period of time after the detection signal of a sensor such as a mat switch has been turned ON, a failure occurs in which the door does not open. If the door closed signal does not turn on after a certain period of time has passed since the sensor detection signal turned off, the failure of the door opening has occurred. There is known a system in which a failure diagnosis device is used for diagnosing and the result of the diagnosis by the failure diagnosis device is notified by a remote computer (for example, refer to Patent Document 1).

  However, in the conventional automatic door monitoring system, when the failure diagnosing device is manufactured by the manufacturer of the automatic door driving device, the algorithm for diagnosing the automatic door failure in the failure diagnosing device is suitable for the automatic door driving device. Therefore, the automatic door failure diagnosis is highly reliable, but the automatic door failure diagnosis algorithm in the failure diagnosis device is not configurable by the administrator of the automatic door monitoring system, so the automatic door failure diagnosis is performed. There is a problem that it is not easy to deal with the new algorithm.

  On the other hand, in the conventional automatic door monitoring system, if the algorithm for diagnosing an automatic door failure in the failure diagnosing device can be set by the administrator of the automatic door monitoring system, a new algorithm for diagnosing an automatic door failure is supported. However, there is a problem that the algorithm for diagnosing the failure of the automatic door is not always suitable for the drive device of the automatic door.

  Therefore, an object of the present invention is to provide an automatic door monitoring system capable of achieving both high reliability of information to be notified and easiness of updating an algorithm for generating information to be notified.

It is characterized by comprising a server that generates information based on one, and an information notification unit that notifies the information generated by at least one of the information generation unit and the server.

By being manufactured by, the reliability of the information generated by the information generation unit can be improved, and the algorithm of information generation in the server is set by the administrator of the automatic door monitoring system, so that The algorithm for generating the generated information can be easily updated. Therefore, the automatic door monitoring system of the present invention can achieve both high reliability of the information notified by the information notification unit and ease of updating the algorithm for generating the information notified by the information notification unit.

  In the automatic door monitoring system of the present invention, the automatic door includes a door and a sensor for detecting an object in the vicinity of the door, and the server generates information based on information output from the sensor. You may.

  With this configuration, the automatic door monitoring system of the present invention generates the information by the server based on the information output from the sensor, so that the information generation unit does not need to generate the information based on the information output from the sensor. Good, when the manufacturer of the automatic door driving device and the manufacturer of the automatic door sensor are different, it is possible to facilitate the manufacturing of the information generation unit by the manufacturer of the automatic door driving device.

The output of information from the controller 48 to the data converter 21 may be executed immediately. The type and format of the information output from the controller 48 differs depending on the manufacturer of the drive device 40. Therefore, the manufacturer of the data converter 21 is preferably the same as the manufacturer of the drive device 40. The data converter 21 can generate failure prediction information and failure information based on the information output from the controller 48, and constitutes the information generation unit of the present invention. The automatic door system 20 includes a data converter for each automatic door.

  The automatic door system 20 includes a relay box 22 that relays information output from the data converter 21, the activation sensor 35, the activation sensor 36, and the auxiliary photoelectric sensor 37.

  The automatic door system 20 includes a relay box for each automatic door. In addition, in the relay box included in the automatic door system 20, the relay box 22 is a master device, and the others are slave devices.

  The automatic door system 20 includes a gateway 23 as a wireless or wired communication device that transmits the information relayed by the relay box to the server 70 (see FIG. 1). The gateway 23 is connected only to the relay box 22 which is the master unit among the relay boxes included in the automatic door system 20.

  The data converter, the relay box, and the gateway can be retrofitted to the automatic door. Therefore, the automatic door owner installs the data converter, the relay box and the gateway for the automatic door only when he / she wants to receive the service using the data converter, the relay box and the gateway. If you do not want to receive the service using the data converter, relay box and gateway, you can install the data converter, relay box and gateway to the automatic door. Can be suppressed.

  The automatic door system 20 may include an automatic door 50 shown in FIG. 5 instead of the automatic door 30 shown in FIG.

  FIG. 5 is a block diagram of the automatic door side system 20 including the automatic door 50.

  Among the configurations of the automatic door side system 20 shown in FIG. 5, the same configurations as the configurations of the automatic door side system 20 shown in FIG. 2 are denoted by the same reference numerals and detailed description thereof will be omitted.

  As shown in FIG. 5, the drive device for the automatic door 50 includes a controller 51 that controls the automatic door 50. As a drive device of the automatic door 50, various manufacturers can be adopted. The controller 51 is a computer. The controller 51 cannot detect the current value of the motor 47.

  The automatic door 50 does not include the clamp type sensor 52 that detects the current value of the motor 47, the activation sensor 35, the activation sensor 36 and the auxiliary photoelectric sensor 37 that support specific communication such as CAN communication, in this communication. And a converter 53 for connecting to a corresponding controller 51. The clamp type sensor 52 detects the current value of the electric wire, that is, the electric current value of the motor 47 by sandwiching the electric wire connecting the motor 47 and the controller 51.

  The data converter 21 processes information output from the controller 51 and information such as a current value output from the clamp sensor 52 into communication data of a specific communication method. Here, as the information output from the controller 51 to the data converter 21, for example, various setting information of the automatic door 50, the current value of the motor 47 in the opening operation of the automatic door 30, and the opening information of the automatic door 30.

The frequency of outputting information from the controller 51 to the data converter 21 is, for example, once every 30 minutes.

  The manufacturer of the data converter 21 is preferably the same as the manufacturer of the drive device for the automatic door 50. If the manufacturer of the data converter 21 is the same as the manufacturer of the drive device for the automatic door 50, the manufacturer of the drive device for the automatic door 50 is the same as the manufacturer of the drive device 40. That is, the data converter 21 may be the same one for the drive device 40 and the drive device for the automatic door 50.

  Next, the operation of the automatic door monitoring system 10 will be described.

  First, the operation of the automatic door monitoring system 10 when the failure prediction information is generated based on the change in the current value of the motor 47 from the normal time will be described.

  FIG. 6 is a flowchart of the operation of the data converter 21 when the abnormality information is generated based on the change in the current value of the motor 47 from the normal state.

  As shown in FIG. 6, the data converter 21 determines, based on the information output from the controller 48, whether or not the automatic door 30 has been opened until it determines that the automatic door 30 has been opened (S101).

  When determining in S101 that the automatic door 30 has been opened, the data converter 21 calculates the average value of the current values of the motor 47 in the entire opening operation of the automatic door 30 this time (S102).

  FIG. 7 is a diagram showing an example of the moving speed of the door 31 when opened by the motor 47.

  As shown in FIG. 7, when the closed door 31 is opened by the motor 47, the controller 48 accelerates the moving speed of the door 31 from the speed zero to the speed v1 by the motor 47 from time zero to time t1, The moving speed of the door 31 is maintained at the speed v1 by the motor 47 from the time t1 to the time t2, and the moving speed of the door 31 is reduced from the speed v1 to the speed v2 by the motor 47 from the time t2 to the time t3. , Between the time t3 and the time t4 the motor 47 maintains the moving speed of the door 31 at the speed v2, and between the time t4 and the time t5 the motor 47 reduces the moving speed of the door 31 from the speed v2 to the zero speed. To do.

  The average value of the current values of the motor 47 in the entire opening operation of the automatic door 30 is the average value of the current values of the motor 47 from time zero to time t5.

  As shown in FIG. 6, after the process of S102, the data converter 21 averages the current value of the motor 47 during the entire opening operation of the automatic door 30 in a normal state (hereinafter, “motor current value normal”). Value)), the average value calculated in S102 is larger than a specific value or more (S103). Here, the data converter 21 stores the normal motor current value in advance. For example, the data converter 21 executes the operation of opening and closing the automatic door 30 by the motor 47 a specific number of times when the setting of the normal value of the motor current value is instructed, and based on the current value of the motor 47 in this operation. Determine the motor current value normal value. The timing at which the setting of the normal motor current value is instructed may be, for example, when the automatic door 30 is installed.

  When the data converter 21 determines in S103 that the average value calculated in S102 is not larger than the specific value by the specific value of the motor current value in S103, the normal information indicating that the current value of the motor 47 is normal ( Hereinafter, "normal motor current value information") is generated (S104), this normal motor current value information is output to the relay box 22 (S105), and the process of S101 is executed.

  When the data converter 21 determines in S103 that the average value calculated in S102 is greater than the normal value of the motor current value by a specific value or more, the data converter 21 indicates abnormality information indicating that the current value of the motor 47 is abnormal (hereinafter referred to as " The motor current value abnormality information "is generated (S106), the motor current value abnormality information is output to the relay box 22 (S107), and the process of S101 is executed.

  The motor current value normality information and the motor current value abnormality information output from the data converter 21 to the relay box 22 are transmitted to the server 70 via the gateway 23.

  FIG. 8 is a flowchart of the operation of the server 70 when the failure prediction information is generated based on the motor current value abnormality information.

  As shown in FIG. 8, the server 70 determines whether the motor current value normal information or the motor current value abnormal information is received until it determines that the motor current value normal information or the motor current value abnormal information is received. (S121).

  When the server 70 determines in S121 that the motor current value normal information or the motor current value abnormal information has been received, the motor current value abnormal information regarding the motor current value normal information and the motor current value abnormal information is continuously received three times. It is determined whether or not (S122).

  When the server 70 determines in S122 that the motor current value abnormality information has not been received three consecutive times, the server 70 executes the process of S121.

  When the server 70 determines in S122 that the motor current value abnormality information has been received three consecutive times, the server 70 generates failure prediction information regarding the current value of the motor 47 (S123). Here, the server 70 may include the degree of deterioration of components such as the door 31, the guide rail 33, the hanger rail 41, and the door hanger 42 related to the change in the current value of the motor 47 in the failure prediction information. For example, the server 70 can acquire the degree of deterioration of components related to the change in the current value of the motor 47 based on the degree of change in the current value of the motor 47 from the normal time.

  After the processing of S123, the server 70 transmits the failure prediction information generated in S123 to the base terminal of the base that manages the automatic door 30 (S124), and executes the processing of S121.

  Upon receiving the failure prediction information transmitted in S124, the site terminal of the site that manages the automatic door 30 notifies the received failure prediction information by, for example, a display. Therefore, the service person at the site that manages the automatic door 30 can perform maintenance work such as telephone or field work according to the failure prediction information notified by the site terminal at this site. The abnormal current value of the motor 47 in the opening operation of the automatic door 30 may be due to, for example, dust on at least one of the door 31 and the guide rail 33, or deformation of at least one of the door 31 and the guide rail 33. Abrasive friction between the door 31 and the guide rail 33 due to wear, or dust attached to at least one of the hanger rail 41 and the door roller 42a of the door hanger 42. Or when at least one of the hanger rail 41 and the door roller 42a is deformed or worn to cause abnormal friction between the hanger rail 41 and the door roller 42a, the opening operation of the automatic door 30 is performed. Is likely to occur if there is an unusual resistance to the movement of the door at. If there is an abnormal resistance to the movement of the door in the opening operation of the automatic door 30, the automatic door 30 may stop operating due to a failure unless some action is taken to remove the resistance. It has a high quality. Therefore, the automatic door monitoring system 10 can support the predictive maintenance of the automatic door 30 by the service person by displaying the failure prediction information on the base terminal.

  In the above, the server 70 generates the failure prediction information when the motor current value abnormality information is continuously received three times. However, the server 70 may generate the failure prediction information when the motor current value abnormality information is continuously received multiple times other than three times. Further, the server 70 may generate the failure prediction information according to a condition other than the condition that the motor current value abnormality information is continuously received a plurality of times. For example, the server 70 may generate failure prediction information when the motor current value abnormality information is received a certain number of times or more in total, or the motor current value abnormality information may be received a certain number of times or more during a certain period. In the case of doing so, failure prediction information may be generated.

  In the automatic door monitoring system 10 described above, the server 70 cooperates with the data converter 21 to generate failure prediction information. However, the data converter 21 and the server 70 may independently generate the failure prediction information based on the change in the current value of the motor 47 from the normal time. For example, when the average value of the current value of the motor 47 in the entire opening operation of the automatic door 30 is larger than the normal motor current value by a specific value or more, the data converter 21 determines the current value of the motor 47. It is also possible to generate failure prediction information regarding the above and output this failure prediction information to the relay box 22. Then, the server 70 may transmit the failure prediction information transmitted from the data converter 21 via the relay box 22 and the gateway 23 to the base terminal of the base managing the automatic door 30.

  The data converter 21 and the server 70 generate the failure prediction information based on the change in the average value of the current values of the motor 47 from the normal state in the entire opening operation of the automatic door 30 as described above. However, at least one of the data converter 21 and the server 70 changes the current value of the motor 47 in the automatic door 30 as a change from the normal state in the current value of the motor 47 in the entire opening operation of the automatic door 30. The failure prediction information may be generated based on a change from a normal value in a value other than the average value. For example, at least one of the data converter 21 and the server 70 controls the current value of the motor 47 in a part of one opening operation of the automatic door 30, for example, from time zero to time t1 in FIG. The failure prediction information may be generated based on the change in the average value of the from the normal time. Further, at least one of the data converter 21 and the server 70 generates failure prediction information based on a change in the average value of the current values of the motor 47 from the normal state in one closing operation of the automatic door 30. Alternatively, the failure prediction information may be generated based on a change in the average value of the current values of the motor 47 from the normal time in both the one-time opening and closing operations of the automatic door 30. Further, at least one of the data converter 21 and the server 70 predicts a failure based on a change from a normal value of a peak value of a current value of the motor 47 in at least one operation of opening and closing the automatic door 30. Information may be generated. The peak value usually occurs from time zero to time t1 in FIG.

  The operation of the automatic door monitoring system 10 when the failure prediction information is generated based on the change in the current value of the motor 47 in the automatic door 30 from the normal time has been described above. However, the current value output from the clamp-type sensor 52 is also used for the operation of the automatic door monitoring system 10 when the failure prediction information is generated based on the change in the current value of the motor 47 in the automatic door 50 from the normal time. It is the same except that it does.

  The above has described the operation of the automatic door monitoring system 10 when the failure prediction information is generated based on the change in the current value of the motor in the automatic door from the normal time. However, at least one of the data converter and the server 70 provides motor failure in the automatic door as failure prediction information in the presence of abnormal resistance to movement of the door in at least one operation of opening and closing the automatic door. Failure prediction information other than failure prediction information based on changes in current value from normal times can be generated by a method similar to failure prediction information based on changes in current values of motors in automatic doors from normal times. ..

  For example, at least one of the data converter and the server 70 may provide failure prediction information based on a change in the average value of the moving speed of the door from the normal state during at least one operation of opening and closing the automatic door, or the like. A door in at least one operation of opening and closing an automatic door, such as failure prediction information based on a change in the maximum value of the moving speed of the door in at least one operation of opening and closing the automatic door from a normal time The failure prediction information based on the change in the moving speed of the vehicle from the normal time can be generated by the same method as the failure prediction information based on the change in the current value of the motor in the automatic door from the normal time. At least one of the data converter and the server 70 includes at least one of opening and closing the automatic door when the moving speed of the door in at least one operation of opening and closing the automatic door is lower than a normal speed by a certain speed or more. It can be determined that there is an abnormal resistance to the movement of the door in one movement.

  Further, at least one of the data converter and the server 70 provides failure prediction information based on a change from a normal time required for at least one operation of opening and closing the automatic door to a motor of the automatic door. It can be generated by the same method as the failure prediction information based on the change in current value from the normal time. At least one of the data converter and the server 70 includes at least one of opening and closing the automatic door when the time required for at least one operation of opening and closing the automatic door is longer than a normal time by a certain time or more. It can be determined that there is an abnormal resistance to the movement of the door in one movement.

  Further, at least one of the data converter and the server 70 performs at least one operation of opening and closing the automatic door when the automatic door is equipped with a vibration sensor for detecting vibration generated in the automatic door. The failure prediction information based on the change in vibration detected by the vibration sensor from the normal time can be generated by the same method as the failure prediction information based on the change in the current value of the motor in the automatic door from the normal time. .. At least one of the data converter and the server 70 is provided for opening and closing the automatic door when the vibration generated in the automatic door increases by a certain degree or more during at least one operation of opening and closing the automatic door. It can be determined that there is abnormal resistance to movement of the door in at least one operation.

  The above describes the failure prediction information in the case where there is an abnormal resistance to the movement of the door in at least one operation of opening and closing the automatic door. However, at least one of the data converter and the server 70 is also responsible for failure prediction information other than failure prediction information in the presence of abnormal resistance to movement of the door in at least one operation of opening and closing the automatic door. , An automatic door opening and closing operation, at least one of which can be generated by a method similar to the failure prediction information when there is an abnormal resistance to the movement of the door.

  For example, at least one of the data converter and the server 70 may provide failure prediction information based on the change in the number of rotations of the motor in the at least one operation of opening and closing the automatic door from the normal time to the automatic door. It can be generated by the same method as the failure prediction information based on the change in the current value of the motor from the normal state in. The movement of the door in the opening direction is stopped by the door hanger coming into contact with the door stopper. Therefore, the number of rotations of the motor in one opening operation of the automatic door is always constant if the automatic door is in a normal state. However, if the timing belt of the drive device extends longer than normal, the distance traveled by the door will be shorter than normal even if the motor rotates the normal number of times. The number of rotations is longer than in normal times. Also, if the screws on the door, guide rails, hanger rails, door hangers, and other parts are loosened, the doors will not stop properly even if the door hangers come into contact with the door stopper. The number of rotations is longer than in normal times. Although the operation of opening the automatic door has been described above, the same applies to the operation of closing the automatic door. Therefore, at least one of the data converter and the server 70 is provided with a timing belt when the number of rotations of the motor in at least one operation of opening and closing the automatic door increases more than a certain number of times from the normal time. It is possible to determine that there is extension of the wire and loosening of screws for parts such as doors, guide rails, hanger rails, and door hangers. For automatic doors, when there is stretch of the timing belt or loosening of screws for doors, guide rails, hanger rails, door hangers, etc., the timing belt stretches, and the door, guide rails, hanger rails, door hangers, etc. Unless some measures are taken to eliminate the looseness of the screws of the parts, there is a high possibility that it will eventually fail due to a failure.

  At least one of the data converter and the server 70 provides failure prediction information based on a change in sensitivity of each sensor such as an activation sensor and an auxiliary photoelectric sensor from a normal time to a motor current value of the automatic door from a normal time. It can be generated by the same method as the failure prediction information based on the change. At least one of the data converter and the server 70 can determine that the sensitivity of the sensor is deteriorated when the sensitivity of the sensor is deteriorated by a certain degree or more with respect to the normal time. Further, at least one of the data converter and the server 70 can determine the degree of deterioration of the sensitivity of each sensor based on the number of times the automatic door is opened and closed, the operating time of each sensor, the number of detections by each sensor, and the like. It is possible to generate failure prediction information based on the determined deterioration degree. If the sensitivity of the sensor is deteriorated, the automatic door is likely to stop operating due to a failure unless some measures are taken to eliminate the deterioration of the sensor sensitivity.

  In the above, the failure prediction information is explained. However, at least one of the data converter and the server 70 can generate information other than the failure prediction information based on the information output from the automatic door.

  For example, at least one of the data converter and the server 70 can generate the failure information of the automatic door based on the information output from the automatic door as well as the failure prediction information. That is, when at least one of the data converter and the server 70 determines that the automatic door is in a state in which the automatic door cannot be opened or closed based on the information output from the automatic door, the failure information of the automatic door is displayed. To generate. Further, at least one of the data converter and the server 70 may generate the failure information of the automatic door when the information that should be notified from the automatic door is not notified for a specific time.

  When there is failure information to be transmitted to the server 70, the relay box immediately transmits the failure information to the server 70 via the gateway, and at least one of the setting information and the maintenance information to be transmitted to the server 70 is transmitted. If it exists, the setting information and the maintenance information to be transmitted to the server 70 are periodically transmitted to the server 70 via the gateway, for example, once a day. If there is failure prediction information to be transmitted to the server 70, the relay box may immediately send the failure prediction information to the server 70 via the gateway, or may periodically send the failure prediction information to the server via the gateway. 70 may be transmitted. The relay box does not immediately transmit a part of the information to the server 70 via the gateway, so that the communication cost required for the gateway to transmit the information can be suppressed.

  When information such as failure prediction information, failure information and abnormality information of the automatic door is generated based on the information output from the automatic door, an algorithm for generating information such as failure prediction information, failure information and abnormality information of the automatic door Is preferably an algorithm suitable for this automatic door drive, and is therefore preferably set by the manufacturer of this drive. However, the algorithm suitable for the drive device of the automatic door may be the know-how of the maker of this drive device, and it may be difficult for the maker to disclose it to the manager of the automatic door monitoring system 10. In the automatic door monitoring system 10, the data converter that generates information such as failure prediction information, failure information, and abnormality information of the automatic door is manufactured by the manufacturer of this automatic door driving device, and thus the data converter is provided. It is possible to reduce the possibility that the algorithm of generating information such as failure prediction information of the automatic door, failure information, and abnormality information is known to the administrator of the automatic door monitoring system 10. Therefore, the manufacturer of the automatic door driving device can provide the administrator of the automatic door monitoring system 10 with a data converter that generates information by an algorithm suitable for the automatic door driving device.

  Since the automatic door monitoring system 10 includes the data converter and the server 70, a data converter that generates information by an algorithm suitable for an automatic door driving device is manufactured by a manufacturer of this driving device. The reliability of the information generated by the data converter can be improved, and the algorithm of the information generation in the server 70 is set by the administrator of the automatic door monitoring system 10 so that the information generated by the server 70 is generated. The algorithm for generating the information to be updated can be easily updated. Therefore, the automatic door monitoring system 10 can achieve both high reliability of the information notified by the base terminal and ease of updating the algorithm for generating the information notified by the base terminal.

  Since the automatic door monitoring system 10 generates information by the server 70 based on the information output from the activation sensor or the auxiliary photoelectric sensor, the information is output by the data converter based on the information output from the activation sensor or the auxiliary photoelectric sensor. Facilitates the manufacture of data converters by manufacturers of automatic door drives when they do not need to be generated and the manufacturers of automatic door drives differ from the manufacturers of automatic door activation or auxiliary photoelectric sensors be able to.
