(Embodiment 1)
FIG. 1 is a schematic diagram showing a configuration of an automatic door system 100 according to the first embodiment. The automatic door system 100 includes an automatic door 10, an automatic door sensor 20, an auxiliary photoelectric sensor 30, an automatic door control device 40, and the like. The automatic door system 100 shown in FIG. 1 is a double door type, and two automatic doors 10 automatically open and close to the left and right. The automatic doors 10 are a pair of left and right, and can reciprocate along a fix 15 that is fixedly arranged with a space left and right, and opens and closes an opening 11 between the left and right fixes 15.

The automatic door 10 is in a fully closed state in which the left and right door end frames 10a are brought into contact with each other and the opening 11 is closed. The automatic door 10 moves so that the door frame 10a is separated, the door frame 10a moves to the vicinity of the upright 15a of the fix 15 and stops, and the opening 11 is opened and is in a fully opened state. The automatic door system 100 may be of a double-sliding door type, a single-sliding door type, a revolving door type, or the like.

The automatic door sensor 20 is arranged, for example, in the eyeless portion 16 above the opening portion 11. The automatic door sensor 20 projects infrared light obliquely downward from the arrangement position in the eyeless portion 16 to enter the automatic door 10. Or an object is detected, and a start signal is output to the automatic door control device 40. Details of the automatic door sensor 20 will be described later.

The auxiliary photoelectric sensor 30 is a photoelectric detection device, and includes a light projector 30a and a light receiver 30b arranged on the upright 15a of the fix 15. The auxiliary photoelectric sensor 30 detects that the light beam passing between the light projector 30a and the light receiver 30b is blocked, and automatically detects detection information indicating that a person or an object is present on the trajectory of the automatic door 10. Output to the door control device 40. Note that the auxiliary photoelectric sensor 30 may be a detection device or the like that is attached to the blind 16 or a light reflection type or an ultrasonic type in addition to the photoelectric type.

When the automatic door control device 40 receives the activation signal from the automatic door sensor 20, the automatic door control device 40 operates the door motor 50 to drive the automatic door 10 until the automatic door 10 is fully opened. After the automatic door 10 is fully opened, the automatic door control device 40 maintains the fully opened state for a certain period of time, operates the door motor 50 in the reverse direction, and drives the automatic door 10 until the fully closed state. When the automatic door control device 40 receives the detection information from the auxiliary photoelectric sensor 30 during the closing drive of the automatic door 10, the automatic door control device 40 reverses the driving direction of the automatic door 10 by the door motor 50 and fully opens the automatic door 10.

FIG. 2 is a block diagram showing a functional configuration of the automatic door system 100 including the information processing device 24 according to the first embodiment. Each block can be realized by an electronic element such as a CPU of a computer or a mechanical component in terms of hardware, and can be realized by a computer program or the like in terms of software, but here, it is achieved through their cooperation. Draws a functional block. Therefore, those skilled in the art will understand that these functional blocks can be realized in various forms by a combination of hardware and software.

The automatic door sensor 20, the automatic door control device 40, and the external connection unit 51 are communicatively connected to each other by CAN (Controller Area Network). The communication connection of the automatic door sensor 20, the automatic door control device 40, and the external connection unit 51 is not limited to CAN, and wireless communication such as WiFi (registered trademark) may be used.

The automatic door sensor 20 includes a sensor unit 21 as a detection element, a communication unit 22, an opening/closing processing unit 23, and an information processing device 24. The communication unit 22 transmits/receives data to/from the automatic door control device 40 and the external connection unit 51. The sensor unit 21 is an infrared reflection type sensor, and includes a light projector that projects infrared light to a detection area described below, and a light receiver that receives reflected light from a person or an object.

FIG. 3 is a schematic diagram showing the detection area 60 on the floor of the sensor unit 21. The detection area 60 is provided around the automatic door 10 and has a three-dimensional range from the floor surface to the seamless 16 where the automatic door sensor 20 is arranged and the ceiling. The detection area 60 is composed of a plurality of detection segments 61 arranged in 12 rows in a direction parallel to the moving direction of the automatic door 10 and 6 rows in a direction orthogonal to the moving direction of the automatic door 10. Addresses 1A, 1B,..., 6K, 6L corresponding to the positions of the array are assigned to the respective detection segments 61. Each assigned address corresponds to the position information of each detection segment 61. The shape of each detection segment 61 and the shape of the entire detection area 60 may be a circle, an ellipse, a rectangle, or a polygon other than a rectangle. The sensor unit 21 may be a radio wave sensor, an ultrasonic sensor, a laser scan sensor, or an image sensor. The detection segment 61 may have various shapes as described above, and the shape changes depending on the sensor system and the like. The detection segment 61 means an individual area obtained by dividing the detection area 60 into a plurality of parts. Conversely, it may be considered that the plurality of detection segments 61 form the detection area 60 as a whole.

A person or an object is detected in each detection segment 61 of the detection area 60, but an activation segment that generates an activation signal for opening and closing the automatic door 10 when the person or the object is detected, and an activation signal that does not generate an activation signal You may make it set a segment. For example, the detection segments 61 (addresses 1A to 5A, 6A to 6L, 1L to 5L) located in the peripheral portion of the detection area 60 are set as invalid segments, and the other detection segments 61 are set as activation segments. Even when the shape of the detection area 60 is a circle, an ellipse, a rectangle, or a polygon other than the rectangle, the detection segment 61 located at the peripheral portion of the detection area 60 may be set as an invalid segment. The position of the detection segment 61 is not limited to the example using the address as described above. The position of the detection segment 61 may be, for example, a coordinate in a coordinate system in the real space defined with the arrangement position of the sensor unit 21 in the seamless 16 as the origin. Further, the position of the detection segment 61 may be a coordinate in a coordinate system in a real space defined with an arbitrary position on the floor surface or the like as an origin, and in any definition, the position of each detection segment 61 is It is enough if it can be uniquely grasped.

Returning to FIG. 2, the opening/closing processing unit 23 of the automatic door sensor 20 generates an activation signal for opening the automatic door 10 according to the detection result of each detection segment 61, and automatically transmits the activation signal via the communication unit 22. Output to the door control device 40.

The opening/closing processing unit 23 monitors the detection level of infrared light corresponding to each detection segment 61 of the sensor unit 21, and detects a first threshold value lower than the detection level when a person or object does not exist in the detection segment 61, and the detection level. It is determined whether a person or an object exists by comparing with a second threshold value higher than the level. The open/close processing unit 23 sequentially acquires the detection level in each detection segment 61 from the sensor unit 21, and determines that a person or an object exists when the detection level is equal to or lower than the first threshold value or equal to or higher than the second threshold value. And generate a start signal.

In addition, when the invalid segment is set as described above, the opening/closing processing unit 23 is activated even when the detection level of the detection segment 61 set as the invalid segment becomes equal to or lower than the first threshold value or equal to or higher than the second threshold value. Do not generate a signal. The opening/closing processor 23 outputs to the information processing device 24 the address of the detection segment 61 whose detection level is equal to or lower than the first threshold or equal to or higher than the second threshold.

The information processing device 24 of the automatic door sensor 20 includes a passage information acquisition unit 24a, an open/closed state acquisition unit 24b, a position identification unit 24c, a distribution acquisition unit 24d, and a storage unit 24e. The storage unit 24e is a storage device including, for example, an SSD (Solid State Drive), a hard disk, a CD-ROM, a DVD, an SD card, or the like.

The passage information acquisition unit 24a obtains passage information indicating that a person or an object has passed through the opening 11 provided with the automatic door 10 based on the detection information obtained from the auxiliary photoelectric sensor 30. As described above, the auxiliary photoelectric sensor 30 outputs detection information indicating that a person or an object is present on the door track, and outputs the detection information to the automatic door control device 40. The passage information acquisition unit 24a uses the detection information of the auxiliary photoelectric sensor 30 acquired via the automatic door control device 40 as passage information indicating that a person or an object has passed through the opening 11 in which the automatic door 10 is provided. It is acquired and output to the position specifying unit 24c.

Further, the passage information acquisition unit 24a detects when a person or an object is detected in the detection segment 61 (for example, the detection segment of the addresses 1B to 1K surrounded by the dotted line in FIG. 3) near the automatic door 10 in the detection area 60. Alternatively, it may be determined that a person or an object has passed through the opening 11 provided with the automatic door 10, and the determination result may be acquired as the passage information. Further, the passage information acquisition unit 24a has passed a person or an object through the opening 11 in which the automatic door 10 is provided based on the information of the detection segment 61 near the automatic door 10 in the detection area on the opposite side of the automatic door 10. Alternatively, the determination result may be acquired as passage information.

The open/closed state acquisition unit 24b acquires the address of the detection segment 61 in which a person or an object is detected from the open/close processing unit 23, and sets the state in which the address of the detection segment 61 is not input as the closed state of the automatic door 10. .. The open/closed state acquisition unit 24b sets the state in which the address of the detection segment 61 is input from the open/close processing unit 23 as the opened state of the automatic door 10. Thus, the open/closed state acquisition unit 24b causes the open/closed state of the automatic door 10 to change from the state in which the address of the detection segment 61 is input from the open/close processing unit 23 to the state in which the address of the detection segment 61 is not input. From the open state to the closed state. Further, the open/closed state acquisition unit 24b acquires the opened/closed state (open state or closed state) of the automatic door 10 from the automatic door control device 40 and outputs it to the position specifying unit 24c.

The position identifying unit 24c has passed a person or an object from the passage information acquiring unit 24a on the door track until the open/closed state of the automatic door 10 input from the open/closed state acquiring unit 24b changes from the open state to the closed state. When the information indicating that is not acquired, the address of the detection segment 61 in which the person or the object is detected is specified. If the passage information indicating that a person or an object has passed through the opening 11 has not been acquired during the period from the open state to the closed state of the automatic door 10, the automatic door 10 may have performed an unnecessary opening/closing operation. There is. When such a case occurs, the position specifying unit 24c specifies the address of the detection segment 61 in which the person or the object is detected in the detection area 60 as the entry position, and in order to investigate the cause of the unnecessary opening/closing operation, The specified address is stored in the storage unit 24e. The position specifying unit 24c enters, for example, the address of the detection segment 61 that first detects a person or an object when the person or the object is detected in the detection area 60 from the state in which the person or the object is not detected. The position is specified and stored in the storage unit 24e.

When specifying the address of the detection segment 61 that was detecting a person or an object, the position specifying unit 24c specifies the detection segment 61 that is first changed from the non-detection state to the detection state at an arbitrary timing depending on the setting. You can The position identifying unit 24c recognizes the detection segment 61 that has changed from the non-detection state to the detection state next to the detection segment that has first changed to the detection state from the state in which some detection segments 61 are in the detection state. Good. The position specifying unit 24c is activated, for example, when an invalid segment is set in the detection area 60 and the invalid segment is set in the peripheral portion, and then the invalid segment is changed to the detection state and then changed to the detection state. The address of the detection segment 61 corresponding to the segment is specified and stored in the storage unit 24e.

The position identifying unit 24c stores the information of the occurrence date and time in the storage unit 24e in addition to the identified address of the detection segment 61.

The distribution acquisition unit 24d uses, as distribution information in the detection area 60, at least two or more addresses of the addresses of the detection segments 61 in the detection area 60, which is the approach position specified by the position specification unit 24c, within a predetermined period. It is acquired and stored in the storage unit 24e. The distribution acquisition unit 24d obtains a distribution by accumulating the number of times specified by the position specifying unit 24c within a predetermined period for each address of the detection segment 61. The predetermined period can be set to any period from any start time. For example, after the automatic door system 100 is installed, a period of one month is set to be a predetermined period, or a period of several months is set to be a predetermined period to determine the cause of the unnecessary opening/closing operation. The data collection period of can be set.

The position identification unit 24c and the distribution acquisition unit 24d communicate with the external device via the external connection unit 51, and store the address and distribution data of the detected segment 61 that is the identified entry position in the external device. Good. To display the address and distribution data of the detection segment 61 specified by the position specifying unit 24c and the distribution acquisition unit 24d on a handy terminal as an external device or an operation PC connected to a network, in order to investigate the cause of the unnecessary opening/closing operation. The support of can be enhanced.

Next, the operation of the automatic door system 100 according to the first embodiment will be described based on the position specifying processing by the information processing device 24. FIG. 4 is a flowchart showing the procedure of the position specifying process by the information processing device 24.

The open/closed state acquisition unit 24b of the information processing device 24 determines whether all the detection segments 61 are in the non-detection state (S1). When all the detection segments 61 are not in the non-detection state (S1: NO), the determination of step S1 is repeated. When the open/close state acquisition unit 24b determines that all the detection segments 61 are in the non-detection state (S1: YES), it determines that the automatic door 10 is in the closed state, and the position specifying unit 24c opens/closes the door. Based on the address of the detection segment 61 input from the processing unit 23, it is determined whether any one of the detection segments 61 is in the detection state (S2). When the address of the detection segment 61 is not input from the opening/closing processing unit 23, the position specifying unit 24c determines that the detection segment 61 is not in the detection state (S2: NO) and repeats the process of step S2.

When the address of the detection segment 61 is input from the opening/closing processing unit 23, the position identifying unit 24c determines that the detection segment 61 is in the detection state (S2: YES), and sets the input address of the detection segment 61 to the entry position. (S3). This state is the state in which a person or an object is first detected in the detection area 60 after the automatic door 10 is closed, and the automatic door 10 shifts to the open state. The open/closed state acquisition unit 24b determines whether or not all the detection segments 61 are in the non-detection state (S4). The open/closed state acquisition unit 24b repeats the determination of step S4 when all the detection segments 61 are not in the non-detection state (S4: NO).

When the open/close state acquisition unit 24b determines that all the detection segments 61 are in the non-detection state (S4: YES), it is determined that the automatic door 10 is in the closed state. The position specifying unit 24c determines whether a person or an object has passed through the opening 11 provided with the automatic door 10 based on the input from the passage information acquisition unit 24a (S5). When the position identification unit 24c determines that a person or an object has passed through the opening 11 based on the input from the passage information acquisition unit 24a (S5: YES), it discards the address of the detection segment 61 identified in step S3. The process ends. When the position identifying unit 24c determines that no person or object has passed through the opening 11 based on the input from the passage information acquiring unit 24a (S5: NO), the address of the detection segment 61 identified in step S3 is stored. The data is stored in the unit 24e (S6), and the process ends.

The position specifying unit 24c and the like of the information processing device 24 repeat the processes of steps S1 to S6 shown in FIG. 4, whereby the storage unit 24e stores information about the unnecessary opening/closing operation that occurs momentarily. FIG. 5 is a chart showing an example of information stored in the storage unit 24e. The information stored in the storage unit 24e includes, for example, the address and date and time of the detection segment 61. The stored information shown in FIG. 5 is read by a mobile terminal or a PC via the external connection unit 51, and it is possible to efficiently check which detection segment 61 has caused many unnecessary opening/closing operations after a person or object is detected. can do.

As a result, the information processing device 24 can provide the position (address) of the detection segment 61 that was in the detection state when the unnecessary opening/closing operation occurred, and assist the cause investigation of the unnecessary opening/closing operation of the automatic door. .. The position identifying unit 24c identifies the address of the detection segment 61 that first detects a person or an object when the detection area 60 changes from the state in which the person or the object is not detected to the state in which the person or the object is detected. By doing so, it is possible to provide information regarding the entry position of the person or the object when the unnecessary opening/closing operation occurs.

The distribution acquisition unit 24d uses, as distribution information in the detection area 60, at least two or more addresses of the addresses of the detection segments 61 in the detection area 60, which is the approach position specified by the position specification unit 24c, within a predetermined period. It is acquired and stored in the storage unit 24e. FIG. 6 is a schematic diagram showing an example of distribution by the distribution acquisition unit 24d.

For example, when a person or an object is detected by the detection segment 61 of the addresses 1A to 6A, 6B to 6K, and 1L to 6L, which is the peripheral portion of the detection area 60, as shown in the distribution shown in FIG. After the person or object enters the detection area 60, it can be determined that the person or object has passed through the automatic door 10 or returned without passing through the automatic door 10.

Further, the portion surrounded by the dotted line in FIG. 6 corresponds to the case which is not the peripheral portion of the detection area 60 but the central portion of the detection area 60 and the first detection segment 61. In such a case, it can be determined that an erroneous detection may have occurred due to an external factor, not a case where a person or an object has entered the detection area 60 and crossed in front of the automatic door 10.

FIG. 7 is a schematic diagram for explaining an example in which an unnecessary opening/closing operation occurs due to an external factor. In the example shown in FIG. 7, the light from the headlight of the vehicle is reflected by the reflector and is radiated into the detection area 60, resulting in erroneous detection. When it is found that the unnecessary opening/closing operation occurs due to such an external factor, it is possible to take a measure such as removing a reflective object to prevent erroneous detection.

As a result, the information processing device 24 can know the range within the detection area 60 that causes the unnecessary opening/closing operation.

Further, the detection area 60 is composed of a plurality of detection segments 61 for detecting a person or an object. The position specifying unit 24c specifies the detection segment 61 as the approach position. Accordingly, the information processing device 24 can identify the position by the detection segment 61.

Further, the distribution acquisition unit 24d integrates the number of times specified by the position specifying unit 24c for each detection segment 61 specified as the approach position.

The passage information acquisition unit 24a acquires passage information indicating that a person or an object has passed through the opening 11. The open/closed state acquisition unit 24b acquires the open/closed state of the automatic door 10. The position identifying unit 24c detects a person or person in the detection area 60 when the passage information acquisition unit 24a does not acquire passage information until the opening/closing state acquired by the opening/closing state acquisition unit 24b changes from the open state to the closed state. The approach position which is the position where the object is detected (address of the detection segment 61) is specified. As a result, the automatic door system 100 can provide the position of the detection segment 61 that is in the detection state when the unnecessary opening/closing operation occurs, and assist the cause investigation of the unnecessary opening/closing operation of the automatic door 10.
