Description

[Technical Field]

[0001] The present invention relates to an automatic door setting system, an automatic door setting method, and an automatic door setting program. [Background technology]

[0002] BACKGROUND ART Conventionally, there is known a system in which a plurality of devices constituting an automatic door system are connected to the same network, and various types of information are transmitted and received between the plurality of devices (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 3-129685 Summary of the Invention [Problem to be solved by the invention]

[0004] When installing an automatic door system such as that described in Patent Document 1 in a building, the installer installs each component device in a predetermined location and also builds a network to enable communication between the components. For example, when connecting the components using CAN (Controller Area Network) communication, it is important to be able to identify which component devices each component device is connected to.

[0005] The task of identifying each component device is often performed manually by the installer using an information processing terminal. Manual registration takes a long time and can cause the automatic door to not function properly due to incorrect registration.

[0006] An object of the present invention is to provide an automatic door setting system, an automatic door setting method, and an automatic door setting program that enable a component device to automatically recognize other component devices. [Means for solving the problem]

[0007] According to one aspect of the present invention, an automatic door setting system includes an information collection unit that is connected to the same network as multiple components that make up an automatic door system, including a protection device that detects people or objects within an area near the front or rear end of the automatic door and outputs a detection signal, and that collects attribute information of the components connected to the network, and an identification unit that identifies whether a component device is a protection device based on the attribute information collected by the information collection unit.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Fig. 1 is a perspective view of an automatic door system according to an embodiment of the present invention.

[0010] As shown in FIG. 1, an automatic door device 10 is equipped with two sliding doors 12. Each sliding door 12 moves toward opposite sides in the width direction of the automatic door device 10 to open, allowing pedestrians or objects to pass through the automatic door device 10. When the sliding doors 12 are in a fully closed state where the door edges are in contact with each other, a fixed portion 14 is provided on each side of the sliding door 12 in the width direction. The fixed portions 14 are fixed to the frame on which the automatic door device 10 is installed. When the sliding door 12 is in a fully open state, the sliding door 12 and the fixed portion 14 face each other, and the space in front of the fixed portion 14 forms a storage portion that stores the sliding door 12 in the fully open state. A guard screen may be provided facing the fixed portion 14.

[0011] The automatic door system 10 is equipped with a transom 16 that houses the drive unit of the sliding door 12, which will be described later. The transom 16 is arranged above the sliding door 12 and the fixed part 14 so as to extend from the end of one fixed part 14 to the end of the other fixed part 14 in the width direction of the automatic door system 10.

[0012] The automatic door system 10 includes a main sensor 18, an auxiliary sensor 20, and two open protection sensors 22L and 22R. The main sensor 18, auxiliary sensor 20, and open protection sensors 22L and 22R are protective devices that detect people or objects within a predetermined area near the sliding door 12. The protective devices of the automatic door system 10 generally refer to devices installed to appropriately protect people or objects passing through the automatic door system 10 and / or people around the automatic door system 10. In addition to the sensors mentioned above, these devices include cameras for image analysis and physical switches such as emergency stop buttons. The main sensor 18 has a predetermined detection area A1 on the path of a person or object approaching the sliding door 12. The main sensor 18 incorporates multiple optical sensors (not shown), and the combined illumination area of ​​each optical sensor defines the detection area A1. When a person or object enters the detection area A1, the main sensor 18 detects it and outputs a detection signal. The detection signal of the main sensor 18 is also used to detect whether a person or object is present within the detection area A1 when closing the sliding door 12. In other words, the main sensor 18 also functions as a closing protection sensor.

[0013] The auxiliary sensor 20 is a photoelectric sensor having a detection area A2 that crosses the opening formed when the sliding door 12 is open. The auxiliary sensor 20 is attached to a vertical frame facing the opening of the fixed part 14. The detection result of the auxiliary sensor 20 is used to detect whether a person or object is present within the detection area A2 before or while the sliding door 12 is being closed. If a person or object is detected within the detection area A2 while the sliding door 12 is being closed, the automatic door system 10 reverses the sliding door 12 to move it toward the fully open position.

[0014] The opening protection sensors 22L, 22R have detection areas A3L, A3R near the storage compartment of each sliding door 12. The opening protection sensors 22L, 22R are provided on the bottom surface of the transom 16 so that the storage compartment becomes the detection areas A3L, A3R. The detection results of the opening protection sensors 22L, 22R are used to detect whether a person or object is present within the detection areas A3L, A3R when the sliding door 12 is opened. If a person or object is detected within the detection areas A3L, A3R before or while the sliding door 12 is opening, the automatic door system 10 reverses the sliding door 12 to move it toward a fully closed state, or stops it.

[0015] Figure 2 is a block diagram of the automatic door setting system. In this embodiment, the automatic door setting system is assumed to be built into the automatic door device. Therefore, the blocks of the automatic door setting system shown in Figure 2 are realized in hardware by the automatic door device.

[0016] As shown in FIG. 2, the automatic door setting system 100 includes a protection device 102, an information collection unit 104, an identification unit 106, a control unit 108, a diagnosis unit 110, a drive unit 112, and an alarm unit 114.

[0017] The protection device 102 includes a main sensor 18, an auxiliary sensor 20, and two open protection sensors 22L and 22R. The protection device 102 detects people or objects within detection areas A1 to A3 near the door edge or door tail, and outputs the detection results as a detection signal. The sensors that make up the protection device 102 are connected to the same network, such as a CAN. Connecting to the same network means that each component device is connected to an open network or a closed network, and is connected so that it can communicate bidirectionally or unidirectionally. Each sensor that makes up the protection device 102 is assigned attribute information that indicates the type of sensor. The attribute information is information composed of a predetermined number or character string, and is unique information assigned to each sensor.

[0018] The information collecting unit 104 is connected to the same network as the protection device 102, and collects attribute information of the protection device 102 via the network. The information collecting unit 104 collects attribute information of the protection device 102 every time it detects that it is in a state where it can communicate with the protection device 102, that is, when the protection device 102 is newly connected to the network or when the protection device 102 is reconnected. The information collecting unit 104 may collect attribute information of a component device other than the protection device 102, for example, the drive unit 112.

[0019] The identification unit 106 identifies attribute information of the sensors constituting the protection device 102 from the multiple pieces of attribute information collected by the information collection unit 104. The identification unit 106 stores in advance attribute information for the main sensor 18, the auxiliary sensor 20, and the two open protection sensors 22L and 22R. The identification unit 106 compares the multiple pieces of attribute information collected by the information collection unit 104 with the stored attribute information and determines whether the attribute information is attribute information of the protection device 102. If the comparison results in the collected attribute information matching the stored attribute information of the sensor, the identification unit 106 identifies the device holding the collected attribute information as a sensor. For example, information indicating a true / false value stored in a specific area of ​​the sensor's memory (so-called "flag information") may be used as the attribute information. In this case, the true / false value indicates whether the sensor is the main sensor 18. The information collection unit 104 reads the information stored in the sensor's memory, and the identification unit 106 identifies the sensor as the main sensor 18 by referring to the true / false value and the condition for the true / false value. After each sensor is identified, the identifying unit 106 stores the attribute information of the identified sensor and outputs it to the control unit 108 .

[0020] The control unit 108 controls the drive unit 112 to control the opening and closing of the sliding door 12 (see FIG. 1). The control unit 108 detects a detection signal from the protection device 102, and outputs an open drive signal or a close drive signal for the sliding door 12 to the drive unit 112 based on the detection signal.

[0021] Furthermore, when the identification unit 106 identifies the sensor, the control unit 108 causes the drive unit 112 to perform an operation to confirm the opening and closing of the sliding door 12. The confirmation operation is performed, for example, after the automatic door system 10 has been installed and each component device has been installed in a predetermined position and the sensor has been identified by the identification unit 106. In this case, after receiving the identification result from the identification unit 106, the control unit 108 outputs an open drive signal and a close drive signal to the drive unit 112 in that order. The order in which the signals are output may be reversed. Therefore, the close drive signal may be output first, and then the open drive signal may be output.

[0022] The diagnosing unit 110 diagnoses the state of the sensor. Diagnosing the state of the sensor by the diagnosing unit 110 means diagnosing at least one of whether the sensor is activated, whether the sensor is connected to a control system including the control unit 108 for communication, and whether the sensor is performing accurate arithmetic processing. The diagnosing unit 110 requests the sensor to perform predetermined information processing and diagnoses whether the sensor is normal based on the processing results on the sensor side. Specifically, the diagnosing unit 110 sends the sensor predetermined problem information and a request for an answer to the problem, and diagnoses the state of the sensor based on the information returned from the sensor. Problem information refers to information that can derive an answer according to a rule, such as an arithmetic operation. The arithmetic operation may be any type as long as the sensor does not have a correct answer (i.e., it is unknown to the sensor) and only the diagnosing unit 110 has the correct answer. To reduce the load of arithmetic processing on the sensor, for example, a two-term arithmetic operation can be used as the arithmetic operation. The information regarding the arithmetic operation may be a mathematical formula itself. Alternatively, a database associating multiple types of mathematical expressions with their numbers may be prepared in advance, the database may be stored in the sensor and the diagnosing unit 110, and the mathematical expression numbers may be transmitted from the diagnosing unit 110 to the sensor as information related to the calculation. If the diagnosing unit 110 is connected to multiple sensors, different mathematical expressions may be transmitted to each sensor. The mathematical expressions transmitted by the diagnosing unit 110 to the sensor may include variables. In this case, the sensor substitutes a numerical value unique to the sensor, such as the sensor's identification number or device number, for the variable and returns the calculation result to the diagnosing unit 110. If the calculation result from the sensor is incorrect, it is clear that some abnormality has occurred at least in the calculation processing unit of the sensor. In such a case, it can be inferred that some abnormality has occurred in the sensor's detection unit as well, and therefore, when the sensor is not performing calculations properly, the diagnosing unit 110 diagnoses that an abnormality has occurred in the sensor.

[0023] The diagnostic unit 110 may be caused to self-diagnose the state of the sensor. Self-diagnosis refers to the sensor self-diagnosing whether or not there is an abnormality in its own function. The diagnostic unit 110 causes the sensor to perform self-diagnosis and receives the results. In response to an instruction from the diagnostic unit 110, the sensor diagnoses whether the sensor's detection function is normal, whether there is any degradation in sensor performance, and whether or not there is any environmental noise in the detection area (foreign matter in the detection area, dirt on the lens, etc.). The diagnostic unit 110 simultaneously transmits a self-diagnosis instruction and a response request to the sensor. The sensor performs the self-diagnosis and calculations in response to the response request in parallel and simultaneously transmits the self-diagnosis results and the calculation results to the diagnostic unit 110. Note that the diagnostic unit 110 may transmit a self-diagnosis instruction to the sensor after receiving the calculation results in response to the response request from the sensor. The diagnostic unit 110 diagnoses whether or not there is an abnormality in the sensor, taking into account the results of the self-diagnosis by the sensor and the calculation results in response to the response request. By performing a diagnosis taking into account the results of the sensor's self-diagnosis, the reliability of the diagnosis results can be increased.

[0024] The diagnostic unit 110 either stores in advance the answer to the calculation sent to the sensor, or performs the calculation itself each time it sends a calculation to the sensor. Therefore, the diagnostic unit 110 stores the correct answer to the calculation sent to the sensor. The diagnostic unit 110 compares the answer from the sensor with the correct answer stored by itself. If the answer and the correct answer are the same, the diagnostic unit 110 diagnoses that the sensor is normal. On the other hand, if the answer and the correct answer are different, the diagnostic unit 110 diagnoses that the sensor is abnormal. The diagnostic unit 110 transmits the diagnostic result to the control unit 108. The diagnostic result of the diagnostic unit 110 may also be output via output means such as a display unit, and the diagnostic result may be communicated to an administrator.

[0025] The drive unit 112 has a drive mechanism such as a door engine, a pulley, etc., and operates the drive mechanism based on an open drive signal or a close drive signal received from the control unit 108. This allows the sliding door 12 to be driven in response to the detection signal of the protection device 102.

[0026] The notification unit 114 notifies the installer of various types of information. The information notified by the notification unit 114 includes information that the information collecting unit 104 has collected attribute information that the identifying unit 106 does not have, and the diagnosis result by the diagnosing unit 110. The notification unit 114 may be an LED or the like that blinks when an abnormality occurs, such as when attribute information that the identifying unit 106 does not have is collected and the diagnosis result by the diagnosing unit 110 is not normal, or may be a monitor or the like that displays information to the installer. Furthermore, the notification unit 114 may notify the installer of this when the diagnosis result by the diagnosing unit 110 is normal.

[0027] The following describes the operation of the automatic door setting system 100. Figure 3 is a flow chart showing a series of operations of the automatic door setting system.

[0028] The automatic door setting system 100 is started up and begins a series of processes after the components of the automatic door device 10 are installed in their predetermined locations. When the components of the automatic door device 10 are connected to the same network and the automatic door setting system 100 is started, the information collection unit 104 acquires attribute information of the devices connected to the network via the network (step S1). The identification unit 106 then references the attribute information acquired by the information collection unit 104 to identify the main sensor 18, the auxiliary sensor 20, and the two open protection sensors 22L and 22R (step S2). The control unit 108 then causes the drive unit 112 to perform an open / close check operation. During the check operation, the diagnosis unit 110 diagnoses whether the protection device 102 is functioning normally (step S3). After the diagnosis is completed, the automatic door setting system 100 ends the series of processes.

[0029] The above-described series of steps is executed by the automatic door system 10 in accordance with instructions based on the control program. Figure 4 is a block diagram of the control program for the automatic door setting system.

[0030] 2 and 4, the control program 200 includes a protection instruction unit 202 that outputs instructions to the protection device 102, a collection instruction unit 204 that outputs instructions to the information collection unit 104, an identification instruction unit 206 that outputs instructions to the identification unit 106, and a diagnosis instruction unit 208 that outputs instructions to the diagnosis unit 110.

[0031] The protection instruction unit 202 causes the protection device 102 to detect people or objects within the detection areas A1 to A3 (see FIG. 1) and output the detection results as a detection signal. The collection instruction unit 204 causes the information collection unit 104 to collect attribute information. The identification instruction unit 206 causes the identification unit 106 to identify the attribute information of the sensor. The diagnosis instruction unit 208 causes the diagnosis unit 110 to diagnose the state of the sensor during the checking operation.

[0032] In this way, the automatic door setting system 100 makes it possible to automatically identify the components simply by installing them in predetermined locations and connecting them via a network. In particular, by automatically identifying which sensors are the main sensor 18, which sensors are the auxiliary sensors 20, which sensors are the open protection sensors 22L, and which sensors are the open protection sensors 22R, the installation process for the automatic door device 10 can be reduced.

[0033] The present invention is not limited to the above-described embodiment, and each configuration of the embodiment can be appropriately modified without departing from the spirit of the present invention.

[0034] The following modifications are envisioned:

[0035] Figure 5 is a block diagram of an automatic door setting system according to a modified example. As shown in Figure 5, the automatic door setting system 300 according to the modified example comprises an automatic door device 302 and an information collection terminal 304. The automatic door device 302 and the information collection terminal 304 are connected via a network 306.

[0036] The automatic door system 302 includes a protection device 102, a control unit 108, a diagnosis unit 110, and a drive unit 112. The information collection terminal 304 includes an information collection unit 104, an identification unit 106, and a notification unit 114.

[0037] The information collection terminal 304 is a terminal that can be operated by the installer, and is configured so that the installer can input predetermined information or output predetermined information to the installer via the notification unit 114. In this way, part of the configuration of the automatic door setting system 300 may be built into the information collection terminal 304.

[0038] The information collecting terminal 304 may also include a position adjustment unit 308 for adjusting the size and position of the detection area. The position adjustment unit 308 displays a position adjustment screen to the installer via the notification unit 114, and outputs to each sensor an instruction to adjust the size and position of the detection area in accordance with an input from the installer.

[0039] FIG. 6 shows a screen for position adjustment. As shown in FIG. 6, the screen shows the sliding door 12 and the detection area A1. The detection area A1 is composed of multiple detection spots 310. In the figure, the sensors corresponding to the detection spots 310 indicated by solid lines are turned ON, making the detection spots 310 detectable. In addition, in the figure, the sensors corresponding to the detection spots 310 indicated by dashed lines are turned OFF, making the detection spots 310 undetectable. The installer refers to the screen and selects the detection spots 310 to be turned ON and the detection spots 310 to be turned OFF, thereby inputting instructions to the information collection terminal 304 to adjust the size and position of the detection area. As a result, only the specified detection spots 310 are turned ON, making it possible to adjust the size and position of the detection area A1. Note that the detection areas A2 and A3 (see FIG. 1) may also be adjustable. [Industrial Applicability]
