Description

The present invention relates to an automatic door driving device that drives a door panel of an automatic door to open and close, an automatic door provided with the automatic door driving device, and an automatic door monitoring system for monitoring the automatic door.

Automatic doors, which automatically open and close the door panel, may not be safely available to humans if a failure occurs. For this reason, automatic doors are required to prevent the occurrence of failures. In this regard, conventionally, the automatic door has been prevented from breaking down by performing regular inspections such as actually visually observing the driving part of the automatic door. However, regular inspections by visiting the site require a great deal of human labor. Therefore, the cost required for maintenance of automatic doors such as periodic inspections tends to increase.

By the way, Patent Document 1 describes an automatic door having a failure monitoring function. The automatic door device of the same document is detected by sensors that detect the presence of an object such as a passerby (“first activation sensor 15”, “second activation sensor 16”, and “auxiliary sensor 17” in FIG. 1 of the same document). Occurrence of failure in the automatic door based on the result and the detection result by the temperature sensor (“temperature sensor 6a” in the figure) that detects the surface temperature of the motor (“motor 6” in the figure) that opens and closes the door panel. The cause is to be monitored (paragraphs 0068 to 0086 of the same document).
Automatic doors In the same document, the fact that a failure has occurred in an automatic door is described in the management center (“Management” in the figure) via the Dopa network (“Dopa network B” in FIG. 1 of the same document), which is a mobile phone communication network. It is also described that it is transmitted to "Center C").

Japanese Unexamined Patent Publication No. 2003-091756

The automatic door of Patent Document 1 can promptly identify the occurrence of a failure in the automatic door and the cause of the failure, and can assist in the prompt repair of the automatic door. However, although the automatic door of Patent Document 1 can detect that a failure has occurred in it, it has not been able to detect that the automatic door is in a state where a failure is likely to occur. Therefore, with the automatic door of the same document, the above-mentioned periodic inspection cannot be labor-saving, and the cost required for the periodic inspection cannot be suppressed.

The present invention has been made to solve the above problems, and it is possible to grasp that the automatic door is in a situation where it is likely to break down, and it is possible to prevent the occurrence of the failure of the automatic door in advance. Is to provide. It is also an object of the present invention to provide an automatic door provided with this automatic door driving device. Furthermore, it is also an object of the present invention to provide an automatic door monitoring system for monitoring this automatic door.

The above issues are
Guide rails provided along the opening and closing direction of the door panel of the automatic door,
A guide roller that rotates while contacting the guide rail, and a roller unit that has a door panel fixing portion that fixes the door panel.
An automatic door drive device including a roller unit drive means for moving the roller unit along a guide rail and an open / close controller for controlling the opening / closing of the door panel by controlling the roller unit drive means.
Provided is an automatic door drive device provided with a guide roller abnormality detecting means for detecting an abnormality of the guide roller or the guide rail by directly or indirectly detecting the vibration of the guide roller or the guide rail. Is solved by.

Here, in the description of "directly or indirectly detecting the vibration of the guide roller or the guide rail", "directly detecting" means the vibration itself (change in acceleration, etc.) generated in the guide roller or the guide rail. Is detected by a sensor attached to the guide roller itself or the guide rail itself. On the other hand, "indirectly detected" in the same description means vibration of a member other than the guide roller (a member that vibrates when the guide roller vibrates) or a member that vibrates with the guide roller. The meaning of detecting the vibration of the guide roller or the guide rail by detecting the vibration of a member other than the guide rail (a member that vibrates when the guide rail vibrates) that is integrally attached to the guide rail. It means that the vibration of the guide roller or guide rail is detected by the change of the physical quantity indirectly related to the vibration such as the loudness of the sound, not the change of the physical quantity directly related to the vibration such as the change of the acceleration. There are two meanings.

As described above, by detecting the vibration of the guide roller or the guide rail by the guide roller abnormality detecting means, it is possible to prevent the occurrence of the failure of the automatic door. This is because most of the causes of automatic door failure are the repeated opening and closing of the door panel with foreign matter (insects, etc.) attached to the guide rollers and guide rails. In other words, if the door panel is repeatedly opened and closed with foreign matter adhering to the guide roller and guide rail, the guide roller and guide rail will be deformed or the guide roller will come off the guide rail, and the door panel will be normal. It will not open or close. In this respect, by detecting the vibration of the guide roller or the guide rail, it is possible to detect that foreign matter has adhered to the guide roller or the guide rail at an early stage.

In the automatic door driving device of the present invention, the detection information by the guide roller abnormality detecting means may be stored in the automatic door driving device itself (such as a memory built in the automatic door driving device). However, in this case, it is necessary to periodically read out and check the detection information stored in the automatic door drive device. For this reason, it is difficult to obtain great results in terms of labor saving in the above-mentioned periodic inspection.

On the other hand, if the guide roller abnormality detecting means detects an abnormality (vibration of the guide roller or the guide rail), the automatic door drive device or a notification means such as a lamp or a speaker provided in the vicinity thereof notifies the detection. , Labor saving of regular inspection can be achieved. However, in this case, although a person who passes by the vicinity of the automatic door can grasp that the automatic door has an abnormality, the information is not always promptly transmitted to the person who maintains the automatic door. However, the maintenance time of the automatic door may be delayed.

Therefore, it is preferable that the automatic door driving device of the present invention is provided with a detection information transmitting means for transmitting the detection information by the guide roller abnormality detecting means to the outside (such as a computer of an automatic door management company). .. As a result, the automatic door management company can quickly grasp that an abnormality has occurred in the automatic door, and can perform maintenance of the automatic door at an early stage. Therefore, it becomes easy to prevent the occurrence of failure of the automatic door.

This configuration
An automatic door monitoring system for monitoring automatic doors that open and close the door panel by rotating the guide roller in the roller unit to which the door panel is fixed while contacting the guide rail and moving the roller unit along the guide rail. There,
A guide roller abnormality detecting means for detecting an abnormality in the guide roller or the guide rail by directly or indirectly detecting the vibration of the guide roller or the guide rail.
A detection information transmission means for transmitting detection information by the guide roller abnormality detection means to the outside,
The detection information receiving means for receiving the detection information transmitted by the detection information transmitting means,
It can be suitably incorporated into an automatic door monitoring system characterized in that the detection information receiving means is provided with an output means for outputting the received detection information.

In the automatic door driving device of the present invention, the guide roller abnormality detecting means is not particularly limited as long as it can directly or indirectly detect the vibration of the guide roller or the guide rail. For example, the guide roller abnormality detecting means can directly or indirectly detect the vibration of the guide roller or the guide rail by detecting the acceleration with the acceleration sensor. Further, the guide roller abnormality detecting means may directly or indirectly detect the vibration of the guide roller or the guide rail by detecting the abnormal noise with the microphone.

The automatic door drive device of the present invention is provided with an open / closed state detecting means for detecting the open / closed state of the door panel and a detection information transmitting means for transmitting the detection information by the open / closed state detecting means to the outside. Is also preferable. This makes it possible to grasp the usage status of automatic doors (number of times the door panel is opened and closed, etc.). The detection information transmitting means for transmitting the detection information by the open / closed state detecting means to the outside can be provided independently of the detection information transmitting means for transmitting the detection information by the guide roller abnormality detecting means to the outside. Usually common.

As described above, according to the present invention, it is possible to grasp that the automatic door is in a situation where a failure is likely to occur, and it is possible to provide an automatic door drive device capable of preventing the occurrence of a failure of the automatic door. It is also possible to provide an automatic door equipped with this automatic door driving device. Further, it becomes possible to provide an automatic door monitoring system for monitoring this automatic door.

A preferred embodiment of the automatic door drive device of the present invention will be described more specifically with reference to the drawings. The configuration described below is an example until you get tired of it. The technical scope of the automatic door drive device of the present invention is not limited to the configuration described below, and can be appropriately modified as long as the gist of the invention is not impaired.

1. 1. Outline of Automatic Door Drive Device The automatic door drive device of the present invention is provided near the door panel of an automatic door such as a building. Sensors for detecting the presence of an object such as a passerby are provided on the front side (the side where the user of the automatic door enters) and the back side (the side where the user of the automatic door exits) of the door panel of the automatic door. When these sensors detect that a pedestrian has entered the front area or the back area of the door panel, the automatic door drive device drives the door panel in the opening direction to open the door panel. When a predetermined time elapses from the opening of the door panel or it is detected that a pedestrian has passed through the automatic door, the automatic door driving device drives the door panel in the closing direction and closes the door panel. In this way, the automatic door drive device drives the door panel to automatically open and close the door panel. The above-mentioned sensor that detects the presence of a passerby in the front area or the back area of the door panel of the automatic door detects the timing of driving the automatic door drive device, and therefore is a "drive sensor" or "startup". It is called a "sensor".

FIG. 1 is a perspective view showing an example of the automatic door driving device 10 according to the present invention. In FIG. 1 and FIG. 2 described later, a coordinate system including an x-axis, a y-axis, and a z-axis is shown. In the following, the x-axis direction in the same coordinate system is referred to as the "left-right" direction, the negative side in the x-axis direction is referred to as the "left" side, the positive side in the x-axis direction is referred to as the "right" side, and the y-axis direction in the same coordinate system is referred to as "right". The "front-back" direction, the negative side in the y-axis direction is called the "front" side or "front" side, the positive side in the y-axis direction is called the "rear" side or "back" side, and the z-axis direction in the same coordinate system is the "up / down" direction. The negative side in the z-axis direction may be referred to as the "lower" side, and the positive side in the z-axis direction may be referred to as the "upper" side. However, these are for convenience of explanation until they get tired of them, and do not limit the direction in which the automatic door drive device 10 of the present invention is installed.

As shown in FIG. 1, the automatic door driving device 10 of the present embodiment includes a mounting base member 11, a guide rail 12, a roller unit 13, a roller unit driving means 14, a guide roller abnormality detecting means 15, and a guide roller abnormality detecting means 15. It is composed of an open / close state detecting means 16, an open / close controller 17, and a detection information transmitting means 18. Each part will be described in detail below.

2. 2. Mounting base member The mounting base member 11 is for mounting the automatic door driving device 10 in the vicinity of the door panel 30 of the automatic door. The mounting base member 11 is usually provided on the upper side of the door panel 30 of the automatic door. In the automatic door driving device 10 of the present embodiment, the mounting base member 11 is arranged in a portion called "transom light" or "column space" on the upper side of the door panel 30 of the door panel 30. The front side (negative side in the y-axis direction in FIG. 1) of the mounting base 11 is covered with a cover (not shown). Therefore, the members such as the guide rail 12 and the roller unit 13 shown in FIG. 1 are invisible from the outside.

3. 3. Guide rail The guide rail 12 is a rail-shaped member provided along the opening / closing direction (x-axis direction in FIG. 1) of the door panel 30. The guide rail 12 guides the roller unit 13, which will be described later, in the opening / closing direction (x-axis direction) of the door panel 30. In the automatic door drive device 10 of the present embodiment, the guide rail 12 is provided at a position along the front edge of the portion (bottom plate portion of the mounting base member 11) protruding forward from the lower edge of the mounting base member 11. There is.

FIG. 2 is a front view showing a state in which the automatic door driving device 10 of FIG. 1 is viewed from the front, and FIG. 2A shows a state in which the door panel 30 is in a closed position (closed state). 2 (b) is a diagram showing a state in which the door panel 30 is in the open position (closed state). As shown in FIG. 2, a stopper 20 for the closing position is provided on one end side of the guide rail 12 (a portion closer to the end on the positive side in the x-axis direction), and the other end side (x-axis) of the guide rail 12 is provided. A stopper 21 for an open position is provided at a portion near the end on the negative side of the direction. As shown in FIG. 2A, the closed position stopper 20 contacts the roller unit 30 so that the door panel 30 in the closed position does not move beyond the closed position in the closed direction (positive side in the x-axis direction). The purpose is to regulate the movement of the roller unit 30. On the other hand, as shown in FIG. 2B, the stopper 20 for the open position is attached to the roller unit 30 so that the door panel 30 in the open position does not move beyond the open position in the open direction (negative side in the x-axis direction). It is for contacting and restricting the movement of the roller unit 30.

4. Roller unit The roller unit 13 moves the door panel 30 in the opening / closing direction (x-axis direction) by moving along the guide rail 12. In the automatic door driving device 10 of the present embodiment, as shown in FIG. 1, the roller unit 13 is composed of a guide roller 13a, a door panel fixing portion 13b, and a belt fixing portion 13c.

The guide roller 13a is a wheel-shaped member that rotates while abutting on the guide rail 12. The guide roller 13a allows the roller unit 13 to smoothly move on the guide rail 12 without resistance. In the automatic door driving device 10 of the present embodiment, the guide rollers 13a are arranged in pairs in the left-right direction (x-axis direction) at predetermined intervals.

The door panel fixing portion 13b is a portion for fixing the door panel 30. As described above, the automatic door driving device 10 of the present embodiment is arranged on the upper side of the door panel 30, and the door panel fixing portion 13b suspends the door panel 30 by fixing the upper part of the door panel 30. It is supposed to be held in the lowered state. As described above, the type of roller unit 13 that holds the door panel 30 in a suspended state is sometimes called a "door hanger".

The belt fixing portion 13c is a portion for fixing to the timing belt 14c in the roller unit driving means 14 described later. That is, the roller unit 13 is fixed to the timing belt 14c via the belt fixing portion 13c. Therefore, the roller unit 13 moves in the opening / closing direction (x-axis direction) following the movement of the timing belt 14c. More specifically, when the roller unit driving means 14 is driven and the portion of the timing belt 14c where the belt fixing portion 13c is fixed moves to the negative side in the x-axis direction (opening direction), the roller unit 13 also moves negative in the x-axis direction. When the timing belt 14c moves to the side (opening direction) and the same portion of the timing belt 14c moves to the positive side in the x-axis direction (closing direction), the roller unit 13 also moves to the positive side (closing direction) in the x-axis direction. ..

5. Roller unit driving means The roller unit driving means 14 is for moving the roller unit 13 along the guide rail 12. The specific configuration of the roller unit driving means 14 is not particularly limited as long as it can exhibit such a function. In the automatic door driving device 10 of the present embodiment, as shown in FIG. 1, the driving pulley 14a, the driven pulley 14b, the timing belt 14c, and the door engine 14d constitute the roller unit driving means 14.

The drive pulley 14a is provided on one end side of the mounting base member 11 (a portion near the end on the positive side in the x-axis direction) in a rotatable state. On the other hand, the driven pulley 14b is provided on the other end side of the mounting base member 11 (a portion closer to the end on the negative side in the x-axis direction) in a rotatable state. An endless (annular) timing belt 14c is hung around the drive pulley 14a and the driven pulley 14b.

The door engine 14d applies a rotational force to the drive pulley 14a to rotate the timing belt 14c hung on the drive pulley 14a and the driven pulley 14b on the positive side in the circumferential direction (clockwise when viewed from the negative side in the y-axis direction) or. It is moved in the opposite direction of the circumferential direction (counterclockwise when viewed from the negative side in the y-axis direction). When the timing belt 14c moves in the circumferential direction, the roller unit 13 fixed to the timing belt 14c and the door panel 30 held in a suspended state on the roller unit 13 move in the direction in which the timing belt 14c moves. ing. As a result, the door panel 30 is moved in the opening direction or the closing direction. The door engine 14d usually uses an electric motor.

6. Guide roller abnormality detecting means The guide roller abnormality detecting means 15 detects an abnormality of the guide roller 13a or the guide rail 12 by directly or indirectly detecting the vibration generated in the guide roller 13a or the guide rail 12. It has become. That is, as described above, if the door panel 30 is repeatedly opened and closed with foreign matter adhering to the guide roller 13a and the guide rail 12, the guide roller 13a and the guide rail 12 may be deformed, or the guide roller 13a may become the guide rail. The door panel 30 does not open and close normally due to the wheel being removed from the wheel 12. In particular, when oil is applied to the guide roller 13a and the guide rail 12 so that the guide roller 13a can move smoothly on the guide rail 12, foreign matter such as insects easily adheres to the oil, and the guide roller 13a is automatically operated. It may cause the door to break down. The guide roller abnormality detecting means 15 prevents foreign matter from adhering to the guide roller 13a and the guide rail 12 which may cause a failure of the automatic door, and the guide roller 13a and the guide rail 12 when the guide roller 13a moves on the guide rail 12. By detecting the vibration that occurs in the automatic door, it is possible to catch a sign of failure of the automatic door.

The guide roller abnormality detecting means 15 is not particularly limited as long as it can directly or indirectly detect the vibration of the guide roller 13a and the guide rail 12. The guide roller abnormality detecting means 15 may directly detect the vibration of the object such as a vibration sensor or an acceleration sensor, or indirectly detect the vibration of the object such as a microphone. May be good. Vibration sensors and acceleration sensors include capacitance type sensors that detect vibration by changing the capacitance of a capacitor composed of an object generated by vibration and a detection unit (electrode), and detection units (coils). A vortex current type that detects vibration by changing the intensity of vortex current generated in an object by passing a high-frequency current, or vibration by an electric signal output by the piezoelectric element that causes deformation in the detection unit (piezoelectric element) due to vibration. An example is a piezoelectric type that detects.

In the automatic door drive device 10 of the present embodiment, as shown in FIG. 3, two types of guide roller abnormality detecting means 15 are provided, an acceleration sensor 15a and a microphone 15b. FIG. 3 is a block diagram showing an example of an automatic door monitoring system including the automatic door driving device 10 according to the present invention. When the vibration (acceleration) detected by the acceleration sensor 15a exceeds a predetermined threshold value, it is determined that an abnormality has occurred in the guide roller 13a or the guide rail 12. Further, when the loudness of the sound detected by the microphone 15b exceeds a predetermined threshold value, it is determined that an abnormality has occurred in the guide roller 13a or the guide rail 12. As described above, by using two types of the guide roller abnormality detecting means 15, it is possible to more reliably detect the abnormality of the guide roller 13a and the guide rail 12.

The location where the guide roller abnormality detecting means 15 is provided is not particularly limited as long as it can detect the vibration or sound generated in the guide roller 13a or the guide rail 12. When a guide roller abnormality detecting means 15 such as the above-mentioned acceleration sensor 15a that directly detects the vibration of an object is used, the guide roller abnormality detecting means 15 is usually a guide roller 13a or a guide rail. It is attached to the 12 itself, or is integrally connected to the guide roller 13a and the guide rail 12, and is attached to a member that vibrates following the vibration of the guide roller 13a and the guide rail 12. On the other hand, when the guide roller abnormality detecting means 15 uses a microphone 15b that detects the vibration of an object by sound, the sound generated from the guide roller 13a and the guide rail 12 can be detected. If so, the guide roller abnormality detecting means 15 can be arranged relatively freely.

In the automatic door drive device 10 of the present embodiment, as shown in FIG. 1, the guide roller abnormality detecting means 15 (acceleration sensor 15a and microphone 15b) is housed in the sensor box 19 attached to the mounting base member 11. There is. In addition to the guide roller abnormality detecting means 15, the sensor box 19 also incorporates a detection information transmitting means 18, which will be described later. As described above, by accommodating the guide roller abnormality detecting means 15 and the detection information transmitting means 18 in a common box (sensor box 19) and unitizing them, the existing automatic door is provided with the automatic door configuration of the present invention. It can be easily converted into a thing.

7. Open / close state detecting means The open / close state detecting means 16 is for detecting the open / closed state of the door panel 30. The open / closed state detecting means 16 includes one that detects that the door panel 30 is in a completely closed and closed state, one that detects that the door panel 30 is in a completely open and open state, and a closed state. And those that detect both the open state and the like are exemplified. The open / closed state detecting means 16 is usually exemplified by a non-contact type sensor such as a proximity sensor or a photoelectric sensor, or a contact type sensor such as a limit switch. By detecting that the door panel 30 has reached the closed position (position to be closed) or the open position (position to be opened) by these sensors, the open / closed state of the door panel 30 can be detected.

In the automatic door drive device 10 of the present embodiment, as shown in FIG. 1, in the middle stage portion of the mounting base member 11 (more strictly, the sensor box 19 fixed to the middle stage portion of the mounting base member 11). The proximity sensor 16a (detection unit) attached downward and the detected unit 16b attached to the upper edge of the roller unit 13 constitute an open / closed state detecting means 16. The proximity sensor 16a and the detected portion 16b overlap each other vertically (in the z-axis direction) when the door panel 30 is closed. Therefore, when the proximity sensor 16a is on (the state in which the proximity sensor 16a is detecting the detected portion 16b), the door panel 30 is in the closed state and the proximity sensor 16a is off (the proximity sensor 16a is detected). When the unit 16b is not detected), it can be determined that the door panel 30 is not in the closed state (is in the open state or the like).

8. Open / Close Controller The open / close controller 17 controls the opening / closing of the door panel 30 by controlling the roller unit driving means 14. That is, in the automatic door drive device 10 of the present embodiment, as described above, the sensor that detects that a pedestrian has entered the area on the front side of the door panel 30 (hereinafter referred to as the "first drive sensor"). The opening / closing controller 17 is provided with a sensor (hereinafter referred to as a "second drive sensor") for detecting that a pedestrian has entered the area on the back side of the door panel 30. When the first drive sensor or the second drive sensor is turned on (a state in which a passerby is detected) while the door panel 30 is in the closed state, a control signal is sent to the roller unit driving means 14 to drive the door panel 30 in the open direction. When a predetermined time elapses after the door panel 30 is opened or a passerby detects that a pedestrian has passed through the opposite side of the door panel 30, the roller unit driving means 14 controls the door panel 30 to drive the door panel 30 in the closing direction. It is designed to output a signal.

The open / close controller 17 is not particularly limited as long as it can exhibit the above functions, but is usually a control board including a CPU. In the automatic door drive device 10 of the present embodiment, the open / close controller 17 uses a control board housed in a box. The place where the opening / closing controller 17 is provided is not particularly limited, but in the automatic door driving device 10 of the present embodiment, it is fixed to the inner surface of the mounting base member 11.

9. Detection information transmitting means The detection information transmitting means 18 is for transmitting the detection information by the guide roller abnormality detecting means 15 to the outside. As described above, in the automatic door driving device 10 of the present embodiment, the open / closed state detecting means 16 for detecting the open / closed state of the door panel 30 is also provided, and the detection information transmitting means 18 is the open / closed state detecting means 16. The detection information by the door is also transmitted to the outside. The configuration of the detection information transmitting means 18 is not particularly limited as long as it can exhibit the above functions. In the automatic door driving device 10 of the present embodiment, as shown in FIG. 3, the transmission base 18a, the transmission control unit 18b, and the transmission module 18c constitute the detection information transmission means 18.

The transmission board 18a is connected to the guide roller abnormality detecting means 15 (acceleration sensor 15a and microphone 15b), the open / closed state detecting means 16 (proximity sensor 16a), the power supply 22, the transmission control unit 18b, and the transmission module 18c. It is an electronic board on which and is mounted. The transmission control unit 18a is a microcomputer having a CPU, and performs various controls related to transmission. The transmission module 18c is for transmitting data (detection information) to the outside. Examples of the transmission module 18c include a SIM module and a WiFi module.

FIG. 4 is a flow chart illustrating an example of processing by the transmission control unit 18b of the detection information transmission means 18 in the automatic door drive device 10 according to the present invention. In the automatic door driving device 10 of the present embodiment, the transmission control unit 18b is executing the process shown in FIG.

That is, the transmission control unit 18b communicates with sensors such as the acceleration sensor 15a, the microphone 15b, and the proximity sensor 16a (step S3 in FIG. 4). Then, when a signal indicating that "the door panel is open (not closed)" is input from the proximity sensor 16a (step S4 in FIG. 4), "open data" is created and transmitted from the transmission module 18c. The process is executed (step S5 in FIG. 4). On the other hand, when a signal indicating that "the door panel is closed (closed)" is input from the proximity sensor 16a (step S6 in FIG. 4), "open / close data" is created and transmitted from the transmission module 18c. The process is executed (step S7 in FIG. 4).

Further, when a signal indicating that "sound has been generated" is input from the microphone 15b (step S8 in FIG. 4), "sound start processing" is executed (step S9 in FIG. 4). Then, when a signal indicating that "the sound has stopped" is input from the microphone 15b (step S10 in FIG. 4), a process of creating "sound data" and transmitting it from the transmission module 18c is executed (). Step S11 in FIG. 4). Further, when a signal indicating that "vibration has occurred" is input from the acceleration sensor 15a (step S12 in FIG. 4), "vibration start processing" is executed (step S13 in FIG. 4). After that, when a signal indicating that "the vibration has stopped" is input from the acceleration sensor 15a (step S14 in FIG. 4), a process of creating "vibration data" and transmitting it from the transmission module 18c is executed. (Step S15 in FIG. 4). When the above series of processes is completed, post-processing (step S16 in FIG. 4) is performed, and the process returns to sensor communication (step S3 in FIG. 4) again.

As described above, the automatic door driving device 10 of the present embodiment indicates that "open data" indicating that the door panel 30 has been opened, "opening / closing data" indicating that the door panel 30 has been closed, and sound have been generated. Various data such as "sound data" and "vibration data" indicating that vibration has occurred are transmitted to the outside by the transmission module 18c (detection information transmission means 18). The destination of data (detection information) is usually a terminal 50 (FIG. 3) such as an automatic door management company. Examples of the terminal 50 include a personal computer terminal, a tablet terminal, and a smartphone.

In the automatic door drive device 10 of the present embodiment, the transmission module 18c (detection information transmission means 18) transmits data (detection information) to the terminal 50 via the cloud 40 as shown in FIG. ing. When a WiFi module is used as the transmission module 18c, a WiFi router is usually interposed between the transmission module 18c and the cloud 40 (cloud server).

By the way, among the various data described above, the "open data" includes the time when the door panel 30 is opened, and the "open / close data" includes the time when the door panel 30 is closed. Further, the "sound data" includes the loudness of sound (sound pressure level, etc.), and the "vibration data" includes the loudness of vibration (acceleration, etc.). These data (log data) are stored in the server (cloud server) in the cloud 40 (FIG. 4), are made easy to see, and are provided on the screen (automatic door monitoring screen) of the terminal 50 (FIG. 4). FIGS. 5 to 7 show an example of an automatic door monitoring screen (screen display of the terminal 50) by the automatic door monitoring system using the automatic door driving device 10 according to the present invention. FIG. 5 shows a state in which the "open / close" tab on the automatic door monitoring screen is activated, FIG. 6 shows a state in which the "error activation" tab on the automatic door monitoring screen is activated, and FIG. 7 shows a state in the automatic door monitoring screen. The state in which the "Sound / Vibration" tab is activated is shown.

As shown in FIG. 5, when the "open / close" tab on the automatic door monitoring screen is activated, the time when the door panel 30 starts to open (the item of "start time" in the figure) and the time when the door panel 30 closes (the item of "start time" in the figure) The "end time" item in the figure), the time from when the door panel 30 starts to open until it finishes closing (the "time" item in the figure), and the loudness of the sound generated when the door panel 30 opens and closes. (Item of "sound" in the figure), magnitude of vibration (acceleration) generated when the door panel 30 opens and closes (item of "vibration" in the figure), and cumulative number of times of opening and closing of the door panel 30 (item of "vibration" in the figure). The "id" item) in the figure can be confirmed in chronological order. Further, with respect to vibration, the respective components (items "X", "Y" and "Z" in FIG. 5) in the x-axis direction, the y-axis direction and the z-axis direction can also be confirmed. Further, it is possible to confirm whether or not an abnormality (error) has occurred (items of "error" and "opening and closing" in FIG. 5) for opening and closing the door panel 30 each time. Furthermore, it is also possible to confirm whether the error that has occurred is related to "sound", "vibration (acceleration)", or "startup".

Further, as shown in FIG. 6, when the "Error start" tab on the automatic door monitoring screen is activated, among the open / close operations recorded in the above cloud server, those in which an error related to "Start" occurs are extracted. It is designed to be displayed. Further, as shown in FIG. 7, when the "Sound / Vibration" tab is activated, an error related to "Sound" or "Vibration (acceleration)" occurs among the opening / closing operations recorded in the above cloud server. Items (those that exceed a predetermined threshold) are extracted and displayed. The threshold values of "sound" and "vibration (acceleration)" recognized as errors may be automatically set by a computer or may be manually input. Furthermore, although not shown in the figure, when the "All" tab on the automatic door monitoring screen is activated, all the open / close operations recorded in the above cloud server that have caused any error are displayed. It has become so.

By the way, in the automatic door monitoring system of the present embodiment, as described above, since the time (opening / closing time) from the start of opening of the door panel 30 to the end of closing is also known, this opening / closing time is monitored and the opening / closing time exceeds the threshold value. Occasionally, it can be grasped that the door panel 30 is in a state of being left open (a state in which the door panel 30 is not closed). This error may also be displayed on the automatic door monitoring screen. In this case, the threshold value of the opening / closing time recognized as an error may be automatically set by the computer or may be manually input.

As described above, in the automatic door monitoring system using the automatic door driving device 10 of the present embodiment, the automatic door fails by confirming the automatic door monitoring screen as shown in FIGS. 5 to 7 on the terminal 50. It is possible to confirm signs that may cause a failure in the near future, not to mention what has happened. Therefore, the failure of the automatic door can be prevented. In addition, since maintenance of automatic doors can be performed without delay when necessary, it is possible to significantly reduce the labor and cost required for maintenance of automatic doors. In addition, even if a failure should occur, it is possible to quickly identify the cause of the failure with high accuracy by checking the situation at the time of the failure. Therefore, it is possible to reduce the labor and cost required for repairing the automatic door.
