(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 are capable of reciprocating along a fix 15 fixedly arranged with a space left and right, and open and close 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 to 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 disposed, for example, in the eyeless portion 16 above the opening portion 11, and emits 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 has 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 and uses a light reflection method or an ultrasonic method in addition to the photoelectric method.

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 it is in the fully opened state. 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 data recording device 24 according to the first embodiment. Each block can be realized by an electronic element such as a CPU of a computer, a mechanical component, or the like in terms of hardware, and a computer program or the like in terms of software, but here, it is achieved by the cooperation thereof. Draws a functional block. Therefore, those skilled in the art will understand that these functional blocks can be realized in various forms by combining 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 a data recording 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 onto 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 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 or 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 collectively form the detection area 60.

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 segment 61 (addresses 1A to 5A, 6A to 6L, 1L to 5L) located in the peripheral portion of the detection area 60 is set as an invalid segment, and the other detection segments 61 are set as activation segments. Even if 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 a 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 coordinates 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 sufficient if it can be uniquely grasped.

Returning to FIG. 2, the opening/closing processing unit 23 of the automatic door sensor 20 generates a start signal for opening the automatic door 10 according to the detection result of each detection segment 61, and automatically transmits the start 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 the first threshold value lower than the detection level when no person or object exists in the detection segment 61, and the detection value. 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 open/close 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 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 to the data recording device 24.

The data recording device 24 of the automatic door sensor 20 includes a predetermined state determination unit 24a, a position specifying unit 24b, a distribution output unit 24c, and a storage unit 24d. The storage unit 24d is a storage device including, for example, an SSD (Solid State Drive), a hard disk, a CD-ROM, a DVD, an SD card, and the like.

The predetermined state determination unit 24a determines whether or not the predetermined state has arisen due to poor passage of a person or an object entering the automatic door 10. FIG. 4 is a chart showing a predetermined state that occurs in a person or an object. The predetermined state includes a door contact state in which a person or an object contacts the automatic door 10, a predicted door contact state in which the automatic door 10 is expected to contact, a stop state in which a person stops before the automatic door 10 and stops, and an automatic state. There is an estimated stoppage state in which the vehicle stops before the door 10 and is expected to stop. Furthermore, a person or an object that has entered from the opposite side of the automatic door 10 is in a U-turn door contact state in which a person or an object comes into contact with the automatic door 10 by a U-turn, and a U-turn door contact expected state in which the contact to the automatic door 10 is expected There is.

The door contact state can be further divided into three states. That is, in the door contact state, a state in which a person or an object contacts the automatic door 10 and the automatic door 10 is stopped, a state in which a person or an object contacts the automatic door 10 and is pushed by the automatic door 10, and There is a state where a person or an object is in contact with the automatic door 10. The state in which a person or an object contacts the automatic door 10 and the automatic door 10 is stopped is determined by the automatic door control device 40 stopping the automatic door 10 when the driving load of the automatic door 10 exceeds an allowable value. .. The state in which a person or an object contacts the automatic door 10 and is pushed by the automatic door 10 is determined by an increase in the drive load of the automatic door 10 in the automatic door control device 40. The state in which a person or an object is in contact with the automatic door 10 is not as high as the state in which the automatic door 10 is pushed, but is determined by the fact that the drive load of the automatic door 10 is slightly increased in the automatic door control device 40. .. These door contact states are the same as the door contact state during U-turn.

The door contact prediction state is a state in which contact with the automatic door 10 is expected based on an approach direction, a walking speed, and a door driving speed, and a state in which the automatic door 10 is moving and a person or an object. There is a state in which the distance between them is less than or equal to a predetermined value (for example, 30 cm or less). The state in which the contact with the automatic door 10 is expected based on the approach direction, the walking speed, and the door driving speed is, for example, the approach direction and the walking speed of a person or an object obtained by the transition of the detection condition of the detection segment 61 in the automatic door sensor 20. It is determined that the opening width of the automatic door 10 based on the door driving speed is equal to or less than a predetermined value (for example, 20 cm or less) when the person or the object arrives at the door, which is calculated based on When the distance between the automatic door 10 and the person or the object is less than or equal to a predetermined value while the automatic door 10 is moving, the position of the detection segment 61 where the automatic door sensor 20 detects the person or the object. Detected by.

In addition to the state shown in FIG. 4, the predicted door contact state may be a state in which the auxiliary photoelectric sensor 30 detects a person or an object on the track of the automatic door 10 while the automatic door 10 is moving in the closing direction. This state is detected by the drive information in the automatic door control device 40 and the detection information by the auxiliary photoelectric sensor 30. The door contact prediction state is similar to the door contact prediction state during U-turn.

The stop state is determined by the detection level in the detection segment 61 of the automatic door sensor 20 continuing the level at which the presence of a person or an object is detected for a predetermined time (for example, 2 seconds or more). Further, the stop state is the opening width of the automatic door 10 when a person or an object is detected by the detection segment 61 (for example, the detection segments of addresses 1B, 1C, and 1K shown in FIG. 3) near the automatic door 10 in the detection area 60. Is less than or equal to a predetermined value (for example, 10 cm or less). The predicted stop state is based on the door driving speed at the time when the person or the object arrives at the door, which is calculated based on the approach direction and the walking speed of the person or the object obtained by the transition of the detection situation of the detection segment 61 in the automatic door sensor 20, for example. It is determined that the opening width of the automatic door 10 is more than a predetermined value and not more than a predetermined value (for example, more than 20 cm and less than 40 cm).

As shown in FIG. 4, the numbers 1 to 12 assigned to the above-described predetermined states are used for identification. The predetermined state determination unit 24a may determine all the predetermined states of numbers 1 to 12, or may determine any one or a plurality of predetermined states. The predetermined state determination unit 24a, when the predetermined states of the numbers 1 to 12 occur, based on the detection status of the automatic door sensor 20 and the driving status of the automatic door control device 40 (status such as driving load and stop), the corresponding predetermined status. The state number is output to the position specifying unit 24b and the distribution output unit 24c.

Based on the address of the detection segment 61 in the detection state input from the opening/closing processing unit 23, the position identifying unit 24b provides the address information of the detection segment 61 for the purpose of investigating the cause of the deterioration of the passability due to the occurrence of the predetermined state. It is stored in the storage unit 24d. The position specifying unit 24b specifies the address of the detection segment 61 that was detecting the person or the object before reaching the predetermined state, and stores the address in the storage unit 24d. For example, when the position specifying unit 24b changes from a state in which no person or object is detected in the detection area 60 to a state in which a person or object is detected, the position specifying unit 24b determines the address of the detection segment 61 that first detects the person or object. It is stored in the storage unit 24d.

When the position specifying unit 24b specifies the address of the detection segment 61 that was detecting a person or object before the predetermined state, the position detection unit 24b first detects the detection state from the non-detection state at an arbitrary timing depending on the setting. The segment 61 can be identified. The position identifying unit 24b 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 24b starts, for example, in the detection area 60, when an invalid segment is set in the peripheral portion, the invalid segment is set to the detection state, and then the non-detection state is set to the detection state. The address of the detection segment 61 corresponding to the segment is specified and stored in the storage unit 24d.

The position identifying unit 24b stores, in addition to the identified address of the detection segment 61, a number in a predetermined state and information on the date and time of occurrence in the storage unit 24d.

The distribution output unit 24c outputs the distribution of addresses of all the detection segments 61 specified by the position specifying unit 24b as distribution information in the detection area 60 within a predetermined period, and stores the distribution information in the storage unit 24d. Further, the distribution output unit 24c outputs the distribution of addresses of at least two or more detection segments 61 among the addresses of the detection segments 61 specified by the position specifying unit 24b as distribution information in the detection area 60 within a predetermined period, You may make it memorize|store in the memory|storage part 24d. The distribution output unit 24c obtains a distribution for each address of the detection segment 61 by integrating the number of times specified by the position specifying unit 24b within a predetermined period. The distribution output unit 24c may output the distribution for all or some of the predetermined states. The predetermined period can be set to any period from any start time. For example, after installing the automatic door system 100, a period of one month is set to be a predetermined period, a period of several months is set regularly to be a predetermined period, and data collection for improving accessibility is performed. You can set the period.

The position specifying unit 24b and the distribution output unit 24c may communicate with an external device via the external connection unit 51 and store the specified address or distribution data of the detection segment 61 in the external device. By displaying the address and distribution data of the detection segment 61 specified by the position specifying unit 24b and the distribution output unit 24c on a handy terminal as an external device or an operation PC connected to a network, support for improving accessibility is provided. Can be enriched.

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 data recording device 24. FIG. 5 is a flowchart showing the procedure of the position specifying process by the data recording device 24.

The position identifying unit 24b of the data recording device 24 determines whether or not 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 position specifying unit 24b determines that all the detection segments 61 are in the non-detection state (S1: YES), next, any one of the detection segments 61 is detected based on the address of the detection segment 61 input from the opening/closing processing unit 23. It is determined whether the segment 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 identifying unit 24b 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 specifying unit 24b determines that the detection segment 61 is in the detection state (S2: YES), and specifies the input address of the detection segment 61. (S3). The predetermined state determination unit 24a determines whether or not a passing person or object is in a predetermined state (S4). When the predetermined state determination unit 24a determines that the person or the object is in the predetermined state (S4: YES), the position specifying unit 24b determines whether or not all the detection segments 61 are in the non-detection state ( S5). If all the detection segments 61 are not in the non-detection state (S5: NO), the position identifying unit 24b repeats the determination of step S5.

When the position specifying unit 24b determines that all the detection segments 61 are in the non-detection state (S5: YES), the position specifying unit 24b stores the address of the detection segment 61 specified in step S3 in the storage unit 24d (S6), and executes the process. finish. If the predetermined state determination unit 24a does not determine that the person or the object is in the predetermined state (S4: NO), the processes of steps S5 and S6 are not performed, and the address of the detection segment 61 specified in step S3 is set. Discard and end the process.

By the position specifying unit 24b and the like repeating the processing of steps S1 to S6 shown in FIG. 5, the information about the predetermined state that occurs moment by moment is stored in the storage unit 24d. FIG. 6 is a chart showing an example of information stored in the storage unit 24d. The information stored in the storage unit 24d includes, for example, the number of the predetermined state, the address of the detection segment 61, the date and time, and the like. The stored information shown in FIG. 6 is read out by the mobile terminal or the PC via the external connection unit 52, and it is efficiently confirmed in which detection segment 61 a predetermined state frequently occurs after a person or an object is detected. be able to.

As a result, the data recording device 24 provides the position (address) of the detection segment 61 that was in the detection state before the generated predetermined state, and supports the efficient grasping of the detection state regarding the improvement of the passability. You can Further, when the detection area 60 changes from a state in which no person or object is detected to a state in which a person or object is detected, the position identifying unit 24b sets the address of the detection segment 61 that first detected the person or object. By specifying, it is possible to provide information regarding the approach position of the person or the object before the predetermined state.

The distribution output unit 24c obtains and outputs the distribution of the addresses of all the detection segments 61 specified by the position specifying unit 24b within a predetermined period based on the information stored in the storage unit 24d, and outputs the distribution to the storage unit 24d. Remember. FIG. 7 is a schematic diagram showing an example of distribution by the distribution output unit 24c. As described above, the distribution output unit 24c may obtain the distribution for all of the predetermined states, or may obtain the distribution extracted for some of the predetermined states.

For example, assuming that the distribution shown in FIG. 7 is obtained by counting contact states of the automatic door 10, that is, numbers 1 to 3 in a predetermined state, detection of the addresses 5A, 6A, and 6B in the detection segment 61. It can be seen that there are many cases where a person or an object entering from the segment 61 contacts the automatic door 10. As a result, the data recording device 24 can assist the efficient grasping of the detection status regarding the improvement of the passability, and for example, the measure for changing the setting of the automatic door sensor 20 such as expanding the left detection area toward the automatic door 10. Can be taken.

FIG. 8 is a schematic diagram showing another example of distribution by the distribution output unit 24c. Assuming that the distribution shown in FIG. 8 is the state of contact with the automatic door 10, that is, the numbers 1 to 3 of the predetermined state are aggregated, the addresses 1D, 1E, 1F, 1G, 1H in the detection segment 61. It can be seen that there are many cases where a person or an object entering from the 1I detection segment 61 contacts the automatic door 10. The detection segments 61 of these addresses 1D to 1I are in the vicinity of the automatic door 10, and in many cases, a person or an object entering from the opposite side of the automatic door 10 makes a U-turn and contacts the automatic door 10. I understand. The automatic door system 100 often performs a process of quickly closing the automatic door 10 for a person or an object moving away from the automatic door 10. When contact with the automatic door 10 due to U-turns occurs frequently, it is possible to take measures such as lengthening the fully open holding time of the automatic door 10 and changing the drive control setting of the automatic door 10. ..

(Modification)
Although the automatic door sensor 20 is provided with the data recording device 24 in the above-described first embodiment, the automatic door control device 40 may be provided with the data recording device 24. FIG. 9 is a block diagram showing a functional configuration of an automatic door system including a data storage device according to a modification.

As shown in FIG. 9, the data recording device 24 is provided in the automatic door control device 40, and the detection information of the detection segment 61 is output from the automatic door sensor 20 to the automatic door control device 40 via a communication connection such as CAN. .. The detection information of the detection segment 61 output from the automatic door sensor 20 is, for example, address information of the detection segment 61 that is in a detection state every moment.

Even when the data recording device 24 is provided in the automatic door control device 40, similar to the first embodiment, the position of the detection segment 61 that was in the detection state before the generated predetermined state is provided to improve the passability. It is possible to support efficient grasp of the detection status.

Next, features of the data recording device 24 and the automatic door system 100 according to the first embodiment and the modified example will be described.
The data recording device 24 includes a predetermined state determination unit 24a and a position specifying unit 24b. The predetermined state determination unit 24a determines whether or not a person or an object that has entered the detection area 60 of the automatic door sensor 20 has reached a predetermined state. When the predetermined state determination unit 24a determines that the predetermined state has been reached, the position specification unit 24b determines the position (address of the detection segment 61) in the detection area 60 that was detecting a person or object before the predetermined state. Identify and remember. As a result, the data recording device 24 can provide the address of the detection segment 61 that was in the detection state before the generated predetermined state, and can assist the efficient grasping of the detection state regarding the improvement of the passability.

Further, the position identifying unit 24b identifies the address of the detection segment 61 that has detected the person or object when the state in which the person or object is not detected in the detection area 60 is changed to the state in which the person or object is detected. As a result, the data recording device 24 can provide the information regarding the approach position of the person or the object before the predetermined state.

Further, the data recording device 24 outputs the address of at least two or more detection segments 61 among the addresses of the detection segments 61 specified by the position specifying unit 24b within a predetermined period as distribution information in the detection area 60. 24c. As a result, the data recording device 24 can assist in grasping the detection position in the detection area 60 when a person or an object is in a predetermined state.

Further, the detection area 60 is composed of a plurality of detection segments for detecting a person or an object. The position specifying unit 24b specifies the detection segment 61 as a position in the detection area 60. The distribution output unit 24c integrates the number of times specified by the position specifying unit 24b for each detection segment 61. Thereby, the data recording device 24 can obtain the distribution based on the number of times of detection for each detection segment 61.

The data recording method includes a predetermined state determination step and a position specifying step. The predetermined state determination step determines whether or not a person or an object that has entered the detection area 60 of the automatic door sensor 20 has reached a predetermined state. The position specifying step specifies a position (address of the detection segment 61) in the detection area 60 where a person or an object was detected before the predetermined state, when the predetermined state determination step determines that the predetermined state has been reached. To remember. According to this data recording method, it is possible to provide the address of the detection segment 61 that was in the detection state before the generated predetermined state, and support the efficient grasping of the detection state regarding the improvement of the passability.

The automatic door system 100 includes an automatic door sensor 20 and an automatic door control device 40. The automatic door sensor 20 is provided in the opening 11 of the building and detects a person or an object that has entered the detection area 60. The automatic door control device 40 opens and closes the automatic door 10 provided in the opening 11 based on the detection state of the automatic door sensor 20. The automatic door sensor 20 or the automatic door control device 40 determines that the predetermined state is determined by the predetermined state determination unit 24a that determines whether the person or the object that has entered the detection area 60 is in the predetermined state, and the predetermined state determination unit 24a. In this case, the position specifying unit 24b that specifies and stores the position in the detection area 60 where the object was detected before the predetermined state is achieved. As a result, the automatic door system 100 can provide the address of the detection segment 61 that was in the detection state before the generated predetermined state, and can assist the efficient grasping of the detection situation regarding the improvement of the passability.
