Description

The present invention relates to an automatic door monitoring system for monitoring the state of automatic doors.

As a conventional automatic door monitoring system, if the door closed signal remains ON even after a certain period of time has passed since the detection signal of a sensor such as a mat switch was turned ON, a failure that prevents the door from opening occurs. If the door close signal does not turn ON after a certain period of time has elapsed since the sensor detection signal turned OFF, it means that the door remains open. is diagnosed by a fault diagnosis device, and the result of the diagnosis by the fault diagnosis device is notified by a remote computer (see, for example, Patent Document 1).

In the configuration of the automatic door-side system 20 shown in FIG. 5, the same configurations as those of the automatic door-side system 20 shown in FIG.

As shown in FIG. 5, the driving device for the automatic door 50 includes a controller 51 that controls the automatic door 50. As shown in FIG.

That is, the data converter 21 can be used in common between the driving device 40 and the driving device of the automatic door 50 .

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

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

FIG. 6 is a flow chart of the operation of the data converter 21 when generating abnormality information 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 whether the automatic door 30 has opened based on the information output from the controller 48 (S101).

When the data converter 21 determines in S101 that the automatic door 30 has opened, it calculates the average current value of the motor 47 in the entire opening operation of the automatic door 30 (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.

As shown in FIG. 7, when the closed door 31 is opened by the motor 47, the controller 48 causes the motor 47 to accelerate the moving speed of the door 31 from zero to v1 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 from the time t2 to the time t3. , the moving speed of the door 31 is maintained at v2 by the motor 47 from time t3 to time t4, and the moving speed of the door 31 is reduced from v2 to zero by the motor 47 from time t4 to time t5. do.

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

As shown in FIG. 6, after the process of S102, the data converter 21 calculates the normal average value of the current value of the motor 47 in the entire opening operation of the automatic door 30 (hereinafter referred to as "normal motor current value ), it is determined whether or not the average value calculated in S102 is greater than a specific value (S103). Here, the data converter 21 stores in advance the motor current value normal value. For example, when the data converter 21 is instructed to set the motor current value normal value, the data converter 21 performs the operation of opening and closing the automatic door 30 by the motor 47 a specific number of times, and based on the current value of the motor 47 in this operation Determine the normal motor current value. For example, when the automatic door 30 is installed can be considered as the timing at which the setting of the normal motor current value is instructed.

When the data converter 21 determines in S103 that the average value calculated in S102 is not larger than the normal value of the motor current value by a specific value or more, the data converter 21 determines that the current value of the motor 47 is normal (normal information ( hereinafter referred to as "motor current value normal information") (S104), this motor current value normal 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 larger than the normal value of the motor current value by a specific value or more, the data converter 21 determines that the current value of the motor 47 is abnormal (hereinafter referred to as " (S106), outputs this motor current value abnormality information to the relay box 22 (S107), and executes the processing of S101.

The normal motor current value information and the abnormal motor current value 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 generating failure prediction information based on motor current value abnormality information.

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

When the server 70 determines in S121 that the normal motor current value information or the abnormal motor current value information has been received, the server 70 has received the abnormal motor current value information three times consecutively regarding the normal motor current value information and the abnormal motor current value information. (S122).

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

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

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

When receiving the failure prediction information transmitted in S124, the base terminal at the base that manages the automatic door 30 notifies the received failure prediction information by, for example, display. Therefore, the service person at the base who manages the automatic door 30 can perform maintenance work such as telephone calls and on-site work according to the failure prediction information notified by the base terminal at this base. An abnormality in the current value of the motor 47 during the opening operation of the automatic door 30 may be caused by, for example, dust adhering to 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. If abnormal friction occurs between the door 31 and the guide rail 33 due to wear, or if dust is 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, causing abnormal friction between the hanger rail 41 and the door roller 42a. This is likely occurring when there is an abnormal resistance to door movement at . If there is abnormal resistance to door movement during the opening operation of the automatic door 30, the automatic door 30 may eventually fail due to failure unless some action is taken to remove this resistance. highly sexual. 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 received three times in succession. However, the server 70 may generate the failure prediction information when the motor current value abnormality information is continuously received a plurality of 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 it receives motor current value abnormality information a total of a specific number of times or more, or may receive motor current value abnormality information a specific number of times or more during a specific period. Failure prediction information may be generated when

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 or 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 state. For example, the data converter 21 determines the current value of the motor 47 when the average value of the current values of the motor 47 in the entire opening operation of the automatic door 30 is greater than the normal value of the motor current value by a specific value or more. may be generated, and the failure prediction information may be output 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 .

As described above, the data converter 21 and the server 70 generate failure prediction information based on the change from normal in the average value of the current value of the motor 47 during the entire operation of opening the automatic door 30 once. However, at least one of the data converter 21 and the server 70 detects the change in the current value of the motor 47 in the automatic door 30 from the normal time, the current value of the motor 47 in the entire opening operation of the automatic door 30 once. Failure prediction information may be generated based on a change from normal in values other than the average value. For example, at least one of the data converter 21 and the server 70 determines the current value of the motor 47 during a part of the operation of opening the automatic door 30 once, such as from time zero to time t1 in FIG. The failure prediction information may be generated based on the change from the normal time of the average value of . In addition, at least one of the data converter 21 and the server 70 generates failure prediction information based on the change from normal in the average current value of the motor 47 in one closing operation of the automatic door 30. Alternatively, the failure prediction information may be generated based on the change from normal in the average current value of the motor 47 in both the opening and closing operations of the automatic door 30 once. In addition, at least one of the data converter 21 and the server 70 performs failure prediction based on the change from normal in the peak current value of the motor 47 in at least one operation of opening and closing the automatic door 30 once. information may be generated. Note that the peak value usually occurs between time zero and time t1 in FIG.

The operation of the automatic door monitoring system 10 when generating failure prediction information based on the change in the current value of the motor 47 in the automatic door 30 from the normal state 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 state. is similar except that

The above describes 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 of the automatic door from the normal state. However, at least one of the data converter and the server 70 provides information on the operation of the motor in the automatic door as failure prediction information when there is 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 can be generated by a method similar to failure prediction information based on changes in motor current value from normal in automatic doors. .

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

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

In addition, at least one of the data converter and the server 70 is provided in at least one operation of opening and closing the automatic door when the automatic door is equipped with a vibration sensor that detects vibration generated in the automatic door. Failure prediction information based on changes in vibration detected by the vibration sensor from normal can be generated in the same manner as failure prediction information based on changes in motor current value from normal in automatic doors. . At least one of the data converter and the server 70 determines whether to open or close the automatic door when the vibration generated in the automatic door increases by a specific degree or more in at least one operation of opening and closing the automatic door. It may be determined that there is an abnormal resistance to movement of the door in at least one motion.

In the above, the failure prediction information when there is an abnormal resistance to the door movement in at least one of the opening and closing operations of the automatic door has been described. However, at least one of the data converter and the server 70 may also provide failure prediction information other than the failure prediction information when there is abnormal resistance to door movement in at least one operation of opening and closing the automatic door. , can be generated in a manner similar to failure prediction information when there is abnormal resistance to door movement in at least one of opening and closing an automatic door.

For example, at least one of the data converter and the server 70 may transmit the failure prediction information based on the change from normal in the number of rotations of the motor in at least one operation of opening and closing the automatic door. It can be generated by the same method as the failure prediction information based on the change from the normal state of the current value of the motor in . The movement of the door in the opening direction is stopped by the contact of the door hanger with the door stopper. Therefore, the number of rotations of the motor in one operation of opening the automatic door is always constant as long as the automatic door is in a normal state. However, if the timing belt of the drive device is stretched more than normal, even if the motor rotates the normal number of times, the door movement distance will be shorter than normal. The number of rotations is longer than normal. Also, if the screws of parts such as doors, guide rails, hanger rails, and door hangers are loosened, the door will not stop properly even if the door hanger comes in contact with the door stopper. The number of rotations is longer than normal. Although the opening operation of the automatic door has been described above, the same applies to the closing operation of the automatic door. Therefore, at least one of the data converter and the server 70 detects when the number of rotations of the motor in at least one operation of opening and closing the automatic door increases by a specific number or more compared to the normal operation. It can be determined that there is an elongation of , or looseness of screws of parts such as doors, guide rails, hanger rails, and door hangers. If the timing belt is stretched or the screws of parts such as doors, guide rails, hanger rails, and door hangers are loose, the timing belt stretches and the doors, guide rails, hanger rails, door hangers, etc. Unless some action is taken to unscrew the part, it is likely that it will eventually fail and become inoperable.

At least one of the data converter and the server 70 outputs failure prediction information based on a change from normal in the sensitivity of each sensor such as an activation sensor and an auxiliary photoelectric sensor to an automatic door motor current value from normal. It can be generated by a method similar to the change-based failure prediction information. At least one of the data converter and the server 70 can determine that the sensitivity of the sensor is degraded when the sensitivity of the sensor is degraded by more than a certain degree from normal. In addition, 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, etc. Failure prediction information can be generated based on the determined degree of deterioration. When the sensitivity of the sensor of the automatic door is degraded, there is a high possibility that the door will eventually stop working due to failure unless some measures are taken to eliminate the degradation of the sensor's sensitivity.

The failure prediction information has been described above. However, at least one of the data converter and the server 70 can also 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 automatic door failure information based on information output from the automatic door in the same manner as failure prediction information. That is, when at least one of the data converter and the server 70 determines that 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 transmitted. Generate. Also, at least one of the data converter and the server 70 may generate this automatic door failure information when the information that should be notified from the automatic door is not notified for a specific period of time.

If there is failure information to be sent to the server 70, the relay box immediately sends the failure information to the server 70 via the gateway, and at least one of the setting information and maintenance information to be sent to the server 70 is If present, the configuration information and security information to be sent to the server 70 are sent to the server 70 via the gateway periodically, such as once a day. If there is failure prediction information to be sent to the server 70, the relay box may immediately send the failure prediction information to the server 70 via the gateway, or periodically send the failure prediction information to the server via the gateway. You can send it to 70. By not transmitting part of the information to the server 70 immediately via the gateway, the relay box can reduce the communication cost required for transmitting the information by the gateway.

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

Since the automatic door monitoring system 10 includes a data converter and a server 70, the data converter that generates information with an algorithm suitable for the drive of the automatic door is manufactured by the manufacturer of this drive. can improve the reliability of the information generated by the data converter, and the information generated by the server 70 is set by the administrator of the automatic door monitoring system 10 by setting the algorithm for generating information in the server 70 Algorithms for generating information 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 generated by the data converter based on the information output from the activation sensor or the auxiliary photoelectric sensor. To facilitate the manufacture of a data converter by a manufacturer of an automatic door driving device when the automatic door driving device does not have to be generated and the automatic door driving device manufacturer and the automatic door activation sensor or auxiliary photoelectric sensor manufacturer are different be able to.
