Description

The present invention relates to an automatic door maintenance assist technique.

Automatic doors that open and close automatically by power such as electricity are widespread and are installed in all types of buildings and facilities. Regular maintenance and inspections are usually performed after installation to ensure the normal operation of automatic doors. With the development of information and communication technology, some maintenance and inspection work can be performed remotely, but it is necessary for workers to go to the installation site to perform failure determination and repair. On the other hand, even if a worker goes to the installation site and carries out maintenance and inspection, there are many cases where no abnormality is found as a result. In this way, maintenance and inspection are indispensable tasks, but there is room for efficiency. In particular, the resources of workers are often limited, and there are strong demands for business operations regarding their efficient use.

Japanese Unexamined Patent Publication No. 2004-316283

As an example of a technique for improving the efficiency of maintenance and inspection of automatic doors, Patent Document 1 discloses a monitoring system that collects information necessary for checking the current status of a large number of automatic doors on one monitoring screen and improves the listability. Has been done. However, due to the limitation of the screen area, there is naturally an upper limit to the number of automatic doors that can be displayed on one screen. In addition, large-scale automatic door operators have installed an extremely large number of automatic doors in various places, and it is not realistic to display the enormous amount of information on one monitoring screen.

The present invention has been made in view of such a situation, and an object thereof is an automatic door maintenance support device capable of appropriately presenting useful information for maintenance and inspection of each automatic door even if a large number of installed automatic doors are installed. To provide.

In order to solve the above problems, the automatic door maintenance support device of a certain aspect of the present invention operates among the operation information acquisition unit that acquires the operation information of a plurality of automatic doors and the operation information acquired by the operation information acquisition unit. It is provided with an information presentation unit that compares and presents operation information of a plurality of automatic doors under approximate operating conditions with similar conditions.

When a large number of automatic doors are installed, the operating conditions differ depending on the installation location, but according to this aspect, the operating information of the automatic doors under the similar operating conditions is compared and information is presented. For multiple automatic doors under approximate operating conditions, all the operating information will be approximated during normal operation, but if there is an abnormality in one of the automatic doors, the operating information will be the other operating information during normal operation. It deviates from the operation information of the automatic door. Therefore, it is possible to accurately detect an abnormality in the automatic door.

Another aspect of the present invention is an automatic door maintenance support method. In this method, among the operation information acquisition step for acquiring the operation information of a plurality of automatic doors and the operation information acquired in the operation information acquisition step, the operation of a plurality of automatic doors under the approximate operation conditions whose operating conditions are close to each other It includes an information presentation step for comparing information and presenting information.

It should be noted that any combination of the above components and the conversion of the expression of the present invention between methods, devices, systems, recording media, computer programs and the like are also effective as aspects of the present invention.

According to the present invention, even if a large number of installed automatic doors are installed, useful information for maintenance and inspection of each automatic door can be appropriately presented based on the approximation of operating conditions.

It is a figure which shows typically the structure of the automatic door maintenance support apparatus which concerns on embodiment. It is a front view which shows the automatic door schematicly. It is a block diagram which shows the function of an automatic door schematicly. It is a list of operation information of the controller and the sensor of the automatic door under the approximate operating conditions.

First, the outline of the embodiment will be described. The automatic door maintenance support device of the present embodiment extracts a small number of automatic doors from a large number of automatic doors based on the approximation of operating conditions. Operating conditions are determined by installation environment data such as temperature and humidity, and unique data such as the weight and dimensions of automatic doors. By extracting and comparing automatic doors with similar operating conditions, it is possible to effectively find automatic doors that may deteriorate or fail.

FIG. 1 schematically shows the configuration of the automatic door maintenance support device 1 according to the embodiment of the present invention. The automatic door maintenance support device 1 supports maintenance work of a large number of automatic doors installed in various places. The automatic door maintenance support device 1 includes an operation information acquisition unit 2, an operation information recording unit 3, an operation condition recording unit 4, an extraction unit 5, a maintenance target automatic door designation unit 6, a diagnosis unit 7, and information presentation. A unit 8 is provided.

Before giving a detailed explanation of the automatic door maintenance support device 1, the automatic door to be the maintenance support target will be described with reference to FIGS. 2 and 3. FIG. 2 is a front view schematically showing the automatic door 100. FIG. 3 is a block diagram schematically showing the function of the automatic door 100.

Each functional block shown in FIG. 3 is realized by a computer having a calculation function, a control function, a storage function, an input function, an output function, various electronic elements, mechanical parts, etc. in terms of hardware, and in terms of software. It is realized by a computer program or the like, but here, a functional block realized by their cooperation is drawn. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms by combining hardware and software.

As shown in FIG. 2 or 3, the automatic door 100 includes a door portion 10 that is driven to open and close, a controller 20 that controls the entire automatic door 100, a sensor 30 that detects a passerby, and a door that generates power. It mainly includes an engine 40 and a power transmission unit 50 that transmits power to the door unit 10. In the following description, the horizontal direction in FIG. 2 is the horizontal direction and the vertical direction in FIG. 2 is the vertical direction. However, the automatic door 100 can be installed in any posture, and the installation direction is the following example. Not limited to.

The door portion 10 overlaps with the first movable door 11L and the second movable door 11R, which are movably provided in the horizontal direction, respectively, and when the first movable door 11L and the second movable door 11R are in the open state. It includes a first fixed door 12L and a second fixed door 12R provided at positions, and a guide mechanism 13 for guiding the horizontal operation of the first movable door 11L and the second movable door 11R. The first movable door 11L, the second movable door 11R, the first fixed door 12L, and the second fixed door 12R are configured in a vertically long rectangular shape in which the vertical dimension is larger than the horizontal dimension. When the door portion 10 is driven open, the first movable door 11L shown on the left side in FIG. 2 is driven to the left, and the second movable door 11R shown on the right side in FIG. 2 is driven to the right side. Further, when the door portion 10 is closed, the first movable door 11L is driven to the right and the second movable door 11R is driven to the left, contrary to the opening drive. The number and shape of the doors constituting the door portion 10 are not limited to the above, and can be appropriately designed according to the needs of the installation location. Similarly, the movable direction of the door portion 10 is not limited to the horizontal direction, and may be a direction inclined from the horizontal direction.

The guide mechanism 13 includes a traveling rail 131, a door roller 132, a guide rail 133, and a steady rest portion 134. The traveling rail 131 is a columnar rail member that extends horizontally over the entire range of motion above the movable doors 11L and 11R. Two door rollers 132 are provided on the upper portions of the movable doors 11L and 11R, respectively, and the movable doors 11L and 11R are suspended on the traveling rail 131. When the movable doors 11L and 11R are driven to open and close in the horizontal direction, the door roller 132 rolls on the traveling rail 131, so that smooth opening and closing operations are possible. The guide rail 133 is a groove-shaped rail member that extends horizontally over the entire range of motion below the movable doors 11L and 11R. The steady rest portion 134 projects from the lower part of the movable doors 11L and 11R and fits in the groove-shaped guide rail 133. When the movable doors 11L and 11R are opened and closed in the horizontal direction, the steady rest portion 134 moves along the guide rail 133, so that the movable doors 11L and 11R are in the prospective direction (the direction perpendicular to the paper surface in FIG. 2). Vibration can be suppressed.

Various parameters related to the opening and closing of the door portion 10 can be set by the controller 20. For example, the opening / closing speed, opening / closing strength, opening width, and the like can be set. The opening / closing speed is the horizontal speed of the first movable door 11L and the second movable door 11R, and the speed directions of both doors are opposite to each other. It is preferable that the speeds (speeds) of both doors are the same, but the speeds may be different. Further, the opening / closing speed may be set to a different value between the normal opening / closing time and the other time. For example, in the case of so-called reversal in which the door portion 10 is switched to the open drive in order to avoid being caught by the closed movable doors 11L and 11R during the normal closed drive, the movable door 11L at the time of the open drive. The speed of 11R may be set to a value different from the speed at the time of normal open driving.

The opening / closing strength is the magnitude of the force at the time of opening / closing the movable doors 11L and 11R, and is controlled by the torque value generated by the motor 41 described later. Similar to the above-mentioned opening / closing speed, it is basically preferable that the movable doors 11L and 11R have the same opening / closing strength. Further, different opening / closing strengths may be set between normal opening / closing and other times. The opening width is the horizontal distance between the first movable door 11L and the second movable door 11R when the door portion 10 is fully opened. As shown in FIG. 2, the moving distance between the fully closed position and the fully open position of the first movable door 11L is W1, and the moving distance between the fully closed position and the fully open position of the second movable door 11R is W2. Then, the opening width is represented by W1 + W2. Here, the moving distances W1 and W2 can be individually set within a range within the horizontal dimension of the automatic door 100.

The controller 20 includes a control unit 21, a door engine drive unit 22, an input / output unit 23, and a storage unit 24. The control unit 21 is realized by an arithmetic processing unit mounted on a microcontroller, and controls various information processing and control in the automatic door 100. The door engine drive unit 22 is composed of an intelligent power module (IPM), and generates a voltage or a current for driving the motor 41 of the door engine 40 under the control of the control unit 21. The input / output unit 23 is composed of an internal interface 231 which is an interface with other components inside the automatic door 100 and an external interface 232 which is an interface with the outside of the automatic door 100.

The internal interface 231 exchanges various information with each part of the automatic door 100 by a wired or wireless connection. In relation to the sensor 30, which will be described later, the detection information of the sensor 30 and the operation information of the sensor 30 (for example, the energization time) are received as input data. Further, the set value (for example, detection sensitivity) of the sensor 30 is provided to the sensor 30 as output data.

The external interface 232 exchanges various information with the communication device outside the automatic door 100 by a wired or wireless connection. For example, the external interface 232 can communicate with a work terminal used by a worker who has gone to the site for installation, maintenance, and inspection of the automatic door 100. As a result, the worker can check the information of each part of the automatic door 100 on the work terminal, and various data of the automatic door 100 (“installation environment data”, “unique data”, “setting data”, etc. described later). Can be entered. When the external interface 232 has a communication function via a public information communication network such as the Internet, information confirmation and data input of the automatic door 100 can be performed from a remote computer.

The storage unit 24 is a general-purpose memory that stores various data of the automatic door 100. In particular, in the present embodiment, the storage unit 24 is used to store the operation information and the operation conditions of the automatic door 100. The details will be described later, but the operation information is information associated with the actual operation of the controller 20 and the sensor 30, and the operation conditions are "installation environment data", "unique data", "setting data", "operation history data", etc. This is information that is a prerequisite for operating the automatic door 100 of. All or part of such information is stored in the storage unit 24 and used in the automatic door maintenance support device 1 of the present embodiment. As will be described later, these operating information and operating conditions are also recorded in a remote server or the like, and can be centrally referred to together with other automatic door operating information and operating conditions.

The sensor 30 includes a start-up sensor 31 and an auxiliary sensor 32. The activation sensor 31 is a photoelectric sensor provided on the surface of the transom 60 above the door portion 10. The activation sensor 31 includes a light projecting unit that emits light such as infrared rays toward the floor surface, and a light receiving unit that detects the reflected light from the floor surface. When a passerby approaches the automatic door 100 and blocks the light, the amount of light received by the light receiving unit changes, so that the passerby can be detected. When the detection information from the start sensor 31 is input to the controller 20 via the internal interface 231, the door engine drive unit 22 drives the motor 41 to open the door unit 10.

The activation sensor 31 may be configured to detect a passerby by reflecting radio waves such as microwaves or ultrasonic waves. Further, as shown as 31A in FIG. 2, the touch plate provided on at least one of the movable doors 11L and 11R may be pushed by a passerby to detect the passerby.

The auxiliary sensor 32 is a photoelectric sensor provided on the first fixed door 12L and the second fixed door 12R of the door portion 10. The auxiliary sensor 32 includes a light emitting unit provided on one of the first fixed door 12L and the second fixed door 12R, and a light receiving unit provided on the other. The light emitting unit and the light receiving unit are provided at the same height from the floor surface, and the light receiving unit detects light such as infrared rays emitted horizontally from the light emitting unit. When the door portion 10 is open and a passerby passes through the opening to block the light, the amount of light received by the light receiving portion changes, so that the passerby can be detected. The main purpose of the auxiliary sensor 32 is closed protection, and when the auxiliary sensor 32 detects a passerby while the movable doors 11L and 11R are closed, the control unit 21 stops the closed drive and switches to the open drive. conduct. This makes it possible to prevent passersby from being pinched by the closed movable doors 11L and 11R. In such closed protection control, by using the detection information of the activation sensor 31 composed of the photoelectric sensor in combination with the auxiliary sensor 32, the detection accuracy of passersby can be improved and the safety can be further improved.

The auxiliary sensor 32 may be configured to detect a passerby by reflecting a radio wave such as a microwave or an ultrasonic wave. Further, the auxiliary sensor 32 may be provided at a place different from the fixed doors 12L and 12R. For example, it may be installed on the transom light 60 like the activation sensor 31, or may be installed on the ceiling near the automatic door 100. If a plurality of such auxiliary sensors 32 are provided, the cost will be high, but the safety will be dramatically improved.

The activation sensor 31 and the auxiliary sensor 32 are provided with an amplifier in the output stage, and the detection value of each sensor is amplified to a predetermined level that can be handled by the controller 20 in the subsequent stage. Therefore, when the detection intensity of the sensor is low, the amplification factor is high, and when the detection intensity of the sensor is high, the amplification factor is low. As described above, the amplification factor of each sensor is data indicating the detection intensity of each sensor.

The door engine 40 includes a motor 41 as a power source for generating rotational power, and a drive pulley 42 that is rotationally driven by the motor 41. The motor 41 can be configured as various known motors, but in the present embodiment, as an example, a brushless motor including an encoder 41A using a Hall element is used. The position of the rotor of the motor 41 detected by the encoder 41A is input to the control unit 21, and the door engine drive unit 22 applies a drive voltage or drive current to the motor 41 accordingly to generate desired rotational power. Will be done. The drive pulley 42 is connected to the rotor of the motor 41 via a gear mechanism (not shown) or the like, and rotates in conjunction with the rotor.

The power transmission unit 50 transmits the power generated by the door engine 40 to the door unit 10 and drives the movable doors 11L and 11R to open and close. The power transmission unit 50 includes a power transmission belt 51, a driven pulley 52, and a connecting member 53. The power transmission belt 51 is an annular timing belt having a large number of teeth formed on its inner peripheral surface, and is wound around a drive pulley 42 on the right side of FIG. 2 and around a driven pulley 52 on the left side of FIG. In this state, the horizontal dimension of the power transmission belt 51 is equal to the horizontal distance between the drive pulley 42 and the driven pulley 52, and is about the same as the horizontal dimension of the movable range of the movable doors 11L and 11R. When the drive pulley 42 is rotated by the motor 41, the driven pulley 52 rotates in conjunction with the power transmission belt 51.

The connecting member 53 connects the movable doors 11L and 11R to the power transmission belt 51, respectively, and drives them to open and close. Here, one movable door is connected to the upper side of the power transmission belt 51, and the other movable door is connected to the lower side of the power transmission belt 51. In the example of FIG. 2, when the power transmission belt 51 rotates counterclockwise, the first movable door 11L moves to the left side and the second movable door 11R moves to the right side, and the power transmission belt 51 moves to the right side. When rotated clockwise, the first movable door 11L moves to the right side and the second movable door 11R moves to the left side, resulting in a closing operation.

When the activation sensor 31 detects a passerby in the automatic door 100 having the above configuration, the door engine 40 generates counterclockwise rotational power under the control of the controller 20 to open and drive the door portion 10. Further, if the state in which no passerby is detected continues for a predetermined time after the open drive, the door engine 40 generates clockwise rotational power under the control of the controller 20 to drive the door portion 10 to close. When the auxiliary sensor 32 or the start sensor 31 detects a passerby during the closed drive, the controller 20 performs reverse control to switch from the closed drive to the open drive.

Returning to FIG. 1, the automatic door maintenance support device 1 of the present embodiment will be described in detail. The automatic door maintenance support device 1 supports maintenance work of a large number of automatic doors A1 to Am installed in various places (m is a natural number). Here, each automatic door A1 to Am typically has a standard configuration as described with reference to FIGS. 2 and 3, but includes automatic doors having different model numbers and specifications. Even if the model number and specifications are the same, the installation environment, installation method, set values, etc. differ for each automatic door, and in that sense, there is no completely identical automatic door. In addition, the operating status after installation also differs for each automatic door.

The operation information acquisition unit 2 acquires operation information of a plurality of automatic doors A1 to Am. The operation information is information associated with the actual operation of each automatic door A1 to Am. The automatic door 100 shown in FIGS. 2 and 3 can be roughly classified into the following operation information.
-Operation information of controller 20-Operation information of sensor 30

Specifically, the operation information of the controller 20 is a voltage, a current, an energization time per drive, and the like when the door engine drive unit 22 drives the motor 41. These operation information can be used for diagnosing deterioration and failure of the automatic door 100. That is, when the automatic door 100 is deteriorated or broken, the desired opening / closing drive cannot be performed with the normal drive voltage or drive current, so that the drive voltage or drive current becomes excessive or too small through the control loop or the like, and an abnormality can be detected. .. Further, when the automatic door 100 is deteriorated or broken, the expected opening / closing drive cannot be performed, so that the energization time becomes longer than usual, and an abnormality can be detected.

Specifically, the operation information of the sensor 30 is the detection strength of the activation sensor 31 and the auxiliary sensor 32, the energization time per detection, and the like. Here, the detection intensity is the amount of light received in the case of a photoelectric sensor. Further, as described above, when an amplifier for amplifying a signal to a predetermined level is provided in the output stage of the sensor, the amplification factor is also the operation information indicating the detection intensity. These operation information can be used for diagnosing deterioration or failure of the automatic door 100, particularly for diagnosing deterioration or failure of the sensor 30 itself. That is, when the sensor 30 is deteriorated or malfunctions, the detection intensity becomes too low (amplification rate is too high) or too high (amplification rate is too low), and an abnormality can be detected. Further, when the sensor 30 is deteriorated or malfunctions, the desired detection operation cannot be performed, so that the energization time becomes longer than usual, and an abnormality can be detected.

The operation information of the automatic door 100 as described above is stored in the storage unit 24, and can be read out and used for maintenance and inspection by the automatic door maintenance support device 1. For example, a worker who has gone to the installation site of the automatic door 100 can connect to the external interface 232 via the work terminal and read the operation information stored in the storage unit 24. In this case, the function of the operation information acquisition unit 2 is realized in the work terminal. When the external interface 232 of the automatic door 100 has a communication function, the operation information stored in the storage unit 24 can be read from a remote computer such as a server via a public information communication network such as the Internet. In this case, the function of the operation information acquisition unit 2 is realized in a remote computer. Further, if the external interface 232 and the remote computer are always connected to the public information communication network, the operation information can be transmitted to the remote computer in real time. In this case, it is not necessary to store the operation information in the storage unit 24.

As is clear from the above explanation, the function of the operation information acquisition unit 2 is not fixedly realized in a specific device, but is required in various devices (work terminal or remote computer). It will be realized accordingly. Then, the operation information of the automatic doors A1 to Am acquired at any time by these operation information acquisition units 2 is centrally recorded in the operation information recording unit 3 configured in the storage area such as a server, and the work of the field worker. It can be accessed at any time from a terminal or a remote computer. Here, the operation information recording unit 3 may record all the operation information of all the automatic doors as they are for the whole period or a certain period, or the average value based on the operation information for the whole period or a certain period. Statistics may be recorded.

The operating condition recording unit 4 records the operating conditions of the plurality of automatic doors A1 to Am. The above-mentioned "operation information" is information associated with the actual operation of the controller and sensor of the automatic door, whereas the "operation condition" is information regarding preconditions for operating the automatic door. The data that make up the operating conditions are roughly classified into the following four types.
(1) Installation environment data (2) Unique data (3) Setting data (4) Operation history data

The installation environment data is data on the area where the automatic door is installed, data on the building or facility where the automatic door is installed, and other data on the installation environment of the automatic door. Data related to the installation area include, for example, temperature, humidity, temperature difference between day and night, wind speed, wind direction, precipitation, weather such as sunshine, weather, weather data related to climate, and damage history of natural disasters such as typhoons and earthquakes. Data on geography and typhoons such as near the sea and mountains. In addition, data on buildings and facilities where automatic doors are installed are, for example, the construction method and structure of the building, the number of floors where automatic doors are installed, the floor plan of the floor where automatic doors are installed, the floor surface, wall surface, and ceiling surface of the automatic door installation location. The material, air conditioning and sunshine conditions at the place where the automatic door is installed, and the type of facility (hospital, school, etc.) can be mentioned.

The unique data includes data on the model number and specifications of the automatic door or its parts, data on the timing and method of installing the automatic door, and the like. The specifications of automatic doors include various data, but the weight, dimensions, shape and material of the door are of particular importance. As the time of installation of the automatic door, in addition to the date of initial installation, the date of replacement or repair can be recorded. As data on the method of installing the automatic door, it is possible to record the installation direction of the automatic door, the mounting height of the activation sensor 31 and the auxiliary sensor 32 from the floor, and the like.

The setting data is a setting value for driving the opening / closing of the automatic door, a setting value for detecting a passerby of the automatic door, and the like. As the set values related to the opening / closing drive, the opening / closing speed, opening / closing strength, and opening width of the door portion 10 described above with respect to FIG. 2 are exemplified. These open / close drive set values are stored in the storage unit 24, and based on this, the door engine drive unit 22 drives the motor 41 to realize a desired open / close speed, open / close strength, and opening width. Further, as the set value for detecting the passerby of the automatic door, the detection sensitivity of the activation sensor 31 and the auxiliary sensor 32 is exemplified. Here, the detection sensitivity is set by a threshold value of the amount of received light for determining that a passerby has been detected. When the threshold value is small, the detection sensitivity is high, and it is determined that the detection was performed even with a small amount of received light. On the contrary, when the threshold value is large, the detection sensitivity is low, and when the amount of received light is small, it is not determined that the detection has occurred.

The operation history data is the number of past opening / closing operations of the automatic door, the past operation rate of the automatic door, and the like. The number of times of opening and closing operations in the past may be the cumulative number of times since the installation, or may be the cumulative number of times within a certain period in the past. Further, it is preferable to separately record the number of times of normal opening / closing operation and the number of times of reversing to open drive during closed drive. This is because the reversing operation imposes a heavy burden on the automatic door as compared with the normal opening / closing operation, and the automatic door having a large number of reversals needs to be preferentially maintained and inspected. The past operating rate can be recorded, for example, as the number of opening / closing operations per day.

Recording of the operating conditions of each automatic door as described above is performed, for example, as follows. Since many of the "installation environment data" and "unique data" basically do not change after the automatic door is installed, these data are recorded together when the automatic door is installed. The recording work may be performed manually by a worker in charge of installation at the site or a supervisor who supervises the installation work remotely, or depending on the item, it may be automatically input without human intervention. Data that changes after installation, for example, meteorological data included in the installation environment data, damage history of natural disasters, and risk data are updated as needed. Since these are data that are not directly related to automatic doors, they can be easily obtained via the Internet or the like without going to the installation site. In addition, even if the unique data changes due to replacement of parts or adjustment of the installation method, it can be updated as appropriate.

In the "setting data", the worker or the supervisor records the initial setting data at the time of installing the automatic door. If the setting data is changed after installation, the operating conditions will be updated accordingly. The "operation history data" is sequentially recorded in the storage unit 24 of each automatic door. When the external interface 232 of the automatic door 100 has a communication function, operation history data may be recorded directly on a remote computer such as a server via a public information communication network such as the Internet.

All or part of the operating conditions of the automatic door 100 as described above can be stored in the local storage unit 24 of the automatic door 100, but automatically based on the manual operation of the worker or the supervisor or via the network. It is preferable to read it out and centrally record it in the operating condition recording unit 4 configured in the storage area such as a server. As a result, in the subsequent stage of the automatic door maintenance support device 1, appropriate processing can be performed with reference to the operating conditions of a large number of automatic doors.

The extraction unit 5 extracts a plurality of automatic doors under the approximate operating conditions based on the operating conditions recorded by the operating condition recording unit 4. Specifically, the automatic door to be maintained designated by the maintenance target automatic door designation unit 6 and other automatic doors having similar operating conditions are extracted.

The maintenance target automatic door designation unit 6 designates the maintenance target automatic door, for example, as follows. When a worker goes to the installation site of a specific automatic door to perform maintenance and inspection work, the automatic door is designated as a maintenance target. Further, any remote automatic door may be designated as a maintenance target based on the operation of the computer. Further, if the maintenance target is not specified in the manual, the computer may periodically specify each automatic door as the maintenance target. In addition, if an automatic door showing signs of deterioration or failure is found, it may be automatically designated as a maintenance target.

The extraction unit 5 determines whether or not the automatic door to be maintained and the other automatic doors are in the approximate operating conditions, and the determination criteria are the above-mentioned "installation environment data" and "unique data". , "Setting data" and "Operation history data" can be set as appropriate.

For example, among the above data constituting the operating conditions, calculable data (for example, climate-related numerical values such as temperature and humidity, weight and dimensions of automatic doors, various set values of automatic doors, past operation of automatic doors) For (values of rate and number of operations), the difference value from the automatic door to be maintained can be calculated, and it can be determined that the automatic door whose value is smaller than a predetermined threshold is in the approximate operation condition. At this time, when the priority of each data is different in the determination of the approximate operating condition, the difference in priority can be reflected by weighting the difference value of each data.

In addition, among the above data constituting the operating conditions, non-calculable data (for example, data on the geography and topography of the area where the automatic door is installed, data on the building where the automatic door is installed, the model number of the automatic door or its parts, automatic) Regarding the door installation method), the criteria for approximation judgment without calculation can be set in advance. For example, regarding the model number, not only the product of the same model number but also the product of another model number belonging to the same product series can be approximated, and the product belonging to another product series can be non-approximate.

The criteria for approximation determination as described above may be set in advance, or may be set by the user each time according to maintenance needs. As an example of the latter, when performing emergency maintenance measures for automatic doors in areas damaged by natural disasters such as typhoons and earthquakes, the automatic doors in the relevant area are extracted based on the area data included in the "installation environment data". The criteria for approximation judgment can be easily set.

By setting an arbitrary approximation determination standard in this way, the extraction unit 5 can extract a plurality of automatic doors under the approximate operating conditions from a desired viewpoint. In the present embodiment, when the extraction unit 5 extracts a plurality of automatic doors from m automatic doors A1 to Am, the automatic door B1 designated by the maintenance target automatic door designation unit 6 and its approximate operating conditions. It is assumed that a total of n automatic doors B1 to Bn of n-1 automatic doors B2 to Bn in the above are extracted. Here, the set of automatic doors B1 to Bn is a subset of the set of automatic doors A1 to Am, and n is m or less.

The diagnosis unit 7 compares the operation information of a plurality of automatic doors B1 to Bn under the approximate operating conditions extracted by the extraction unit 5 among the operation information acquired by the operation information acquisition unit 2, and compares the operation information of the automatic doors B1 to Bn. The diagnosis is made, and the information presentation unit 8 presents the diagnosis result and other information. The simplest mode of information presentation is a list of operation information of n controllers and sensors of automatic doors B1 to Bn as shown in FIG. The value of each operation information of each automatic door displayed in each cell may be the current instantaneous value or the latest value, or may be a statistical value such as an average value based on the operation information for a certain period. Here, since the n automatic doors B1 to Bn are in the approximate operating conditions, if all of them are operating normally, there should be no significant difference in the operating information. On the other hand, when the automatic door is deteriorated or broken, an abnormality occurs in the operation information as described above.

Therefore, in the list of FIG. 4, if there is an automatic door whose operation information is significantly different from that of other automatic doors, deterioration or failure of the automatic door is suspected, and maintenance measures can be given preferentially. Here, in order to make it easier to find such an abnormal value in the list, it is advisable to highlight and display the cell of the operation information significantly different from other automatic doors and the cell of the automatic door number. It should be noted that this information presentation is mainly performed for the automatic door B1 designated by the maintenance target automatic door designation unit 6, but as a result, there is no abnormality in the operation information of the automatic door B1, and rather the other automatic doors B2 to It may be possible to find an abnormality in the operation information of Bn. Therefore, according to the present embodiment, it is possible to effectively find an automatic door that may be deteriorated or broken from among a large number of automatic doors.

In addition, even if there are no significant signs of deterioration or failure when the automatic doors are individually diagnosed, by comparing the operation information with other automatic doors under the approximate operating conditions in the list of FIG. 4, it is still possible. It is possible to detect slight signs of deterioration or failure that have not become apparent. Therefore, according to the present embodiment, it is possible to detect signs of deterioration or failure at an early stage and take preventive measures promptly.

In the example of FIG. 4, the information presentation unit 8 presents a list and prompts the user who sees the list to diagnose the automatic door, but the diagnosis unit 7 autonomously displays the operation information of the automatic doors B1 to Bn. The above diagnosis may be made by comparison, and the information presenting unit 8 may present the diagnosis result. The mode of presenting the diagnosis result at this time is arbitrary, but at least the diagnosis result of the automatic door B1 designated by the maintenance target automatic door designation unit is presented, and in addition, an abnormality is found in the other automatic doors B2 to Bn. If so, it is preferable to notify it.

Further, the automatic door maintenance support device 1 as described above can be used not only for maintenance support after the installation of the automatic door but also for construction quality control at the time of installing the automatic door. When installing a new automatic door, the operating conditions are recorded in advance in the operating condition recording unit 4, and the maintenance target automatic door designation unit 6 designates the operating conditions as maintenance targets. Then, the extraction unit 5 extracts the newly installed automatic door and other installed automatic doors under the approximate operating conditions, and the diagnosis unit 7 and the information presenting unit 8 compare the operation information of the newly installed automatic door and the installed automatic door. And present information. The operation information of newly installed automatic doors is acquired at any time by the work terminal (operation information acquisition unit 2) during construction or confirmation of construction by the workers at the installation site, and the operation information of other installed automatic doors that are in the approximate operating conditions. If there is no significant difference, it can be judged that the construction quality is good. On the other hand, if there is a significant difference in operation information between the newly installed automatic door and the installed automatic door, it is highly possible that the newly installed automatic door is not installed properly, and the worker makes the necessary adjustment work on the spot. be able to.
