(Embodiment 1)
FIG. 1 is a schematic view showing the configuration of the automatic door system 100 according to the first embodiment. The automatic door system 100 shown in FIG. 1 functions to lock and unlock the automatic door 10 with an electric lock 30, detect the intrusion of a person or an object into the automatic door 10 by the automatic door sensor 20, and open / close the automatic door 10. .. The automatic door system 100 includes an automatic door 10, an automatic door sensor 20, an electric lock 30, a door controller 40, and the like. The automatic door 10 shown in FIG. 1 is a double-drawing door type, and the two automatic doors 10 automatically open and close to the left and right. The automatic doors 10 are a pair on the left and right, and can be reciprocated along the fixed 15 fixedly arranged at a space on the left and right, and open and close the opening 11 between the left and right fixeds 15.

The automatic door 10 is in a fully closed state in which the opening 11 is closed by contacting the left and right door tip frames 10a so as to be abutted against each other. The automatic door 10 is locked by the electric lock 30 in the fully closed state. The electric lock 30 is arranged around an automatic door 10 such as a transom 16 above the opening 11. With the electric lock 30 unlocked, the automatic door 10 moves so that the door tip stile 10a separates, the door tip stile 10a moves to the vicinity of the mullion 15a of the fix 15, stops, and the opening 11 Is fully open. The automatic door 10 may be a double sliding door type, a single sliding door type, a revolving door type, or the like.

The automatic door sensor 20 is, for example, an infrared reflection type sensor, which is arranged in the transom 16 described above, and emits and receives infrared light obliquely downward from the arrangement position in the transom 16 to form a detection area. The shape of the detection area may be a polygon other than a circle, an ellipse, a rectangle, or a rectangle. The automatic door sensor 20 monitors whether or not a person or an object has entered the detection area. The automatic door sensor 20 determines whether or not a person or an object has entered the detection area, and if it determines that the object has entered, generates an activation signal and outputs the start signal to the door controller 40. The automatic door sensor 20 detects by the Doppler effect using radio waves or sound waves, acquires an image with a camera and detects it by image processing, measures the distance to a person or an object and detects it, and receives far infrared rays. Those that detect the presence of a person or an object based on the quantity, those that detect by thermography, and the like can be used.

The door controller 40 acquires a start signal from the automatic door sensor 20 as a result of determining whether or not a person or an object has entered the detection area, operates the door motor 50, and drives the automatic door 10 to open or close. After the automatic door 10 is fully opened, the door controller 40 keeps the fully open state for a certain period of time, operates the door motor 50 in the reverse direction, and drives the automatic door 10 until the automatic door 10 is fully closed. Further, the door controller 40 has a function of automatically discriminating the type of the electric lock 30, and energizes the electric lock 30 to lock and unlock according to the discriminated type of the electric lock 30. The door controller 40 corresponds to the electric lock discriminating device in the present invention. Further, the automatic door system 100 corresponds to the electric lock discrimination system in the present invention.

Each block can be realized by electronic elements such as a computer CPU and mechanical parts in terms of hardware, and by a computer program in terms of software, but here, it is realized by cooperation between them. I'm drawing a functional block. 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.

The automatic door sensor 20 and the door controller 40 are communicated with each other by a CAN (Controller Area Network) bus. The communication connection between the automatic door sensor 20 and the door controller 40 is not limited to CAN, and wired or wireless communication such as Ethernet (registered trademark) or WiFi (registered trademark) may be used. The automatic door 10 can be attached by selecting at least one from a plurality of electric locks 30 having different applied voltages for operating the automatic door 10 so as to limit the opening operation. The electric lock 30 is electrically connected to the door controller 40 by a connection cable 60. The connection cable 60 corresponds to the connection portion according to the claim of the present application.

FIG. 3 is a chart showing the types of the electric lock 30. The electric lock A is in the unlocked state when no voltage is applied, the applied voltage is 70 V, and there is no output of a lock / unlock signal indicating whether the lock or unlock is performed. The electric lock B1 is in the locked state when the voltage is not applied, and the electric lock B2 is in the unlocked state when the voltage is not applied, and the applied voltage is both 30 V. Both the electric locks B1 and B2 have an output of a lock / unlock signal.

Here, the locking / unlocking signal includes a locking / unlocking signal, and in the case of a locking signal, it is turned on at the time of locking and OFF, and in the case of an unlocking signal, it is turned off at the time of locking and turned on at the time of unlocking. The locking / unlocking signals output by the electric locks B1 and B2 are unlocking signals, which are ON at the time of unlocking and OFF at the time of locking.

The electric lock control unit 42 includes the rated applied voltage of various electric locks 30 that may be connected as the voltage applied to the electric lock 30. The electric lock control unit 42 can apply each applied voltage of 30V and 70V to the electric lock 30 so that the locking / unlocking can be controlled regardless of which of the electric locks 30 shown in FIG. 3 is connected. Further, the electric lock control unit 42 receives a lock / unlock signal as a signal indicating whether the electric lock 30 is locked or unlocked, and performs control based on the lock / unlock signal, output to the door drive unit 41, and the like. .. The electric lock control unit 42 and the lock / unlock signal input unit 43 described later may be housed in the same device as the door drive unit 41, or may be configured as different devices.

The lock / unlock signal input unit 43 is an input terminal portion of a lock / unlock signal as a signal indicating whether the electric lock 30 is locked or unlocked. 4 (a) to 4 (c) are schematic views showing the connection between the electric lock 30 and the door controller 40. FIG. 4A shows the connection between the electric lock A and the door controller 40, FIG. 4B shows the connection between the electric locks B1 and B2 and the door controller 40, and FIG. 4C shows the electric locks C1 and C2. It represents the connection with the door controller 40. In FIGS. 4A to 4C, the connector a is the connector on the electric lock 30 side, the connector b is the connector of the connection cable 60 connected to the connector a, and the connector d is the connector on the door controller 40 side. , Connector c represents the connector of the connection cable 60 connected to the connector d. The connection cable 60 has a configuration including a cable itself as a signal line and connectors at both ends of the cable, and three connection cables A, B, and C will be described below as examples.

The electric lock A, the electric locks B1 and B2, and the electric locks C1 and C2 are connected to the voltage + side and voltage-side terminals for applying a voltage. The electric lock A shown in FIG. 4A is connected by a connection cable A so that the lock / unlock signal input terminal 43a in the lock / unlock signal input unit 43 of the door controller 40 is in an open state. The connector a on the electric lock A side has a terminal corresponding to the lock / unlock signal input terminal 43a open. The connector b of the connection cable A is a female type and is connected to the connector a (male type) on the electric lock A side. The connection cable A has a signal line connected to each of the voltage + side and voltage-side terminals on the door controller 40 side, and a signal line connected to the locking / unlocking signal input unit 43.

The electric locks B1 and B2 shown in FIG. 4B are connected by a connection cable B so that the lock / unlock signal input terminal 43a is connected to the lock / unlock output on the electric lock side. The connection cable B is equivalent to the connection cable A, and has a signal line connected to each terminal on the voltage + side and the voltage-side on the door controller 40 side, and a signal line connected to the locking / unlocking signal input unit 43. There is.

The electric locks C1 and C2 shown in FIG. 4C are connected by a connection cable C so that the lock / unlock signal input terminal 43a in the lock / unlock signal input unit 43 of the door controller 40 is short-circuited. In the connectors a on the electric locks C1 and C2 sides, the terminals corresponding to the lock / unlock signal input terminals 43a are in a short-circuited state. The connection cable C is equivalent to the connection cable A, and has a signal line connected to each of the voltage + side and voltage-side terminals on the door controller 40 side and a signal line connected to the lock / unlock signal input unit 43. There is. As described above, the connection cables A, B and C are equivalent. Further, the connector a on the electric lock 30 side and the connector d on the door controller 40 side may be connected without using the connection cables A, B and C.

The open / close determination unit 44 determines whether or not the automatic door 10 has been opened when the automatic door 10 is driven by the door drive unit 41. When the electric lock 30 is unlocked, the automatic door 10 is normally driven by the door driving unit 41, and the open / close determination unit 44 determines that the automatic door 10 has been opened. On the other hand, when the electric lock 30 is locked, the automatic door 10 does not move even if the door driving unit 41 tries to drive the automatic door 10, and the open / close determination unit 44 determines that the automatic door 10 has not opened. It will be. Whether or not the automatic door 10 has been opened is determined by whether or not the drive motor (not shown) in the door drive unit 41 is operating normally. For example, the door driving unit 41 determines that the door driving unit 41 has not opened when the load for driving the automatic door 10 is increasing.

The type determination unit 45 is based on determination factors such as application of a voltage from the electric lock control unit 42 to the electric lock 30, the state of the lock / unlock signal, and the determination result of the open / close determination unit 44 when the automatic door 10 is driven. , The type of the electric lock 30 is determined. If the electric lock 30 is equipped with a dedicated controller, the door controller 40 only needs to request the dedicated controller to lock or unlock the electric lock 30, but the automatic door system for the dedicated controller is sufficient. The number of devices constituting 100 increases. Further, a connection cable between the electric lock 30 and the dedicated controller, a connection cable between the dedicated controller and the door controller 40, and the like are also required, which tends to increase the cost. In order to reduce the number of devices and reduce the cost of the automatic door system 100, the electric lock 30 and the door controller 40 are connected by a connection cable 60 without using a dedicated controller, and the electric lock 30 is connected by the type determination unit 45. The type is automatically determined. The type determination unit 45 may be housed in the same device as the electric lock control unit 42, or may be configured as a separate device. Further, the open / close determination unit 44 may be housed in the same device as the type determination unit 45, or may be configured as another device.

The notification unit 46 notifies the outside of the type of the electric lock 30 determined by the type determination unit 45. The notification unit 46 may notify the type of the electric lock 30 by a method such as voice or display, and may output the type to an external device such as a handy terminal for maintenance and inspection to notify the notification. The notification unit 46 can provide confirmation information of the type of the electric lock 30 to the on-site builder at the time of construction of the automatic door system 100, and can automatically know whether or not the automatic door system 100 has been correctly determined.

Next, the operation of the automatic door system 100 will be described based on the type determination process of the electric lock 30 in the door controller 40. FIG. 5 is a flowchart showing the procedure of the type determination process of the electric lock 30. It is assumed that the electric lock 30 connected to the door controller 40 is any of the above-mentioned electric locks A, B1, B2, C1 and C2. Further, the electric lock 30 may be connected to the door controller 40 by the connection cable 60, or may be connected without the connection cable 60. Further, the electric locks B1 and B2 output an unlocking signal as a locking / unlocking signal. In the following example, a case where the unlocking signal is output from the electric lock 30 will be described, but the locking / unlocking signal is output as the locking / unlocking signal. The same applies when it is done.

The type determination unit 45 commands the electric lock control unit 42 to set the voltage applied to the electric lock 30 to a voltage setting state of 0 V, and confirms the state of the unlock signal in the lock / unlock signal input unit 43 ( S1). Next, the type determination unit 45 commands the electric lock control unit 42 to set the voltage applied to the electric lock 30 to a voltage setting state of 30 V, and confirms the state of the unlock signal in the lock / unlock signal input unit 43. (S2). The type determination unit 45 determines whether or not the state of the confirmed unlocking signal has changed from step S1 to step S2 (S3).

If it is a determination result that the state of the unlock signal has changed in step S3 (S3: YES), it means that either the electric locks B1 and B2 are connected, and the type determination unit 45 unlocks. It is determined whether or not the signal has changed from ON to OFF (S4). When the type determination unit 45 determines in step S4 that the unlocking signal has changed from ON to OFF (S4: YES), it determines that it is the electric lock B2 (S5), and ends the process. Further, when the unlocking signal is changed from OFF to ON in step S4 and the type determination unit 45 determines that the lock is not (S4: NO), the type determination unit 45 determines that the lock is B1 (S6), and ends the process. To do.

If it is determined in step S3 that the state of the unlocking signal has not changed (S3: NO), it means that any of the electric locks A, C1 and C2 is connected, and the type determination unit 45 , It is determined whether or not the unlocking signal is always OFF (S7). When the type determination unit 45 determines in step S7 that the unlock signal is always OFF (S7: YES), it determines that it is the electric lock A (S8), and ends the process.

When the type determination unit 45 determines in step S7 that the unlock signal is not always OFF (S7: NO), the type determination unit 45 instructs the electric lock control unit 42 to set the voltage applied to the electric lock 30 to 0V (S7: NO). S9), the door drive unit 41 is instructed to open the automatic door 10 (S10). The open / close determination unit 44 determines whether or not the automatic door 10 has been opened when the automatic door 10 is driven by the door drive unit 41 (S11). When it is determined in step S11 that the automatic door 10 has been opened (S11: YES), the type determination unit 45 determines that the automatic door 10 is the electric lock C1 (S12), and ends the process. When it is determined in step S11 that the automatic door 10 has not opened (S11: NO), the type determination unit 45 determines that the automatic door 10 is the electric lock C2 (S13), and ends the process.

The door controller 40 can determine the types of the electric locks A, B1, B2, C1 and C2 from step S1 to step S13. Neither the electric lock C1 nor C2 has a lock / unlock signal output, the electric lock C1 is an unlock type when no voltage is applied, and the electric lock C2 is a lock type when no voltage is applied. The type determination unit 45 is either electric lock C1 or C2 regardless of the presence or absence of a lock / unlock signal from the electric lock 30 by setting the voltage applied to the electric lock 30 to 0 V and opening the automatic door 10. Can be determined.

The door driving unit 41 may drive the automatic door 10 in a limited manner with, for example, a low driving torque or a predetermined opening width, whereby the opening operation of the automatic door 10 at the time of class determination of the electric lock 30 is minimized. It is possible to limit the damage to the automatic door 10 and prevent an excessive load from being applied.

Further, the electric lock control unit 42 sets the voltage setting state to the electric lock 30 to 0V and 30V, which are low applied voltages, so that an excessive load is not applied to the electric lock 30 at the time of type determination. it can.

Like the electric locks C1 and C2, the electric lock A has no output of a locking / unlocking signal and is an unlocking type when no voltage is applied. The type determination unit 45 is connected to the electric lock 30 when the lock / unlock signal input unit 43 is open and the lock / unlock signal input is always OFF for the determination between the electric lock A and the electric locks C1 and C2. Is determined to be the electric lock A. Further, the type determination unit 45 determines that the connected electric locks 30 are electric locks C1 and C2 when the lock / unlock signal input unit 43 is in a short-circuited state and the lock / unlock signal input is always ON.

In the discrimination between the electric lock A and the electric locks C1 and C2, it is utilized that the lock / unlock signal input terminal 43a of the lock / unlock signal input unit 43 is in a short-circuited state or an opened state. As a result, the type determination unit 45 can determine the type of the two types of electric locks 30 that do not output the lock / unlock signal without driving the automatic door 10.

Both the electric locks B1 and B2 have a lock / unlock signal output, the electric lock B1 is a lock type when no voltage is applied, and the electric lock B2 is a lock type when no voltage is applied. The type determination unit 45 determines the electric locks B1 and B2 from the other electric locks A, C1 and C2, and the electric lock 30 is connected when the lock / unlock signal is changed by the lock / unlock signal input unit 43. Is determined to be the electric locks B1 and B2. As a result, the type determination unit 45 can determine the type of the electric lock having no lock / unlock signal output and the electric lock having the lock / unlock signal output.

FIG. 6 is a flowchart showing a procedure of another type determination process of the electric lock 30. The type determination unit 45 commands the electric lock control unit 42 to set the voltage applied to the electric lock 30 to 0 V, and confirms the state of the unlock signal in the lock / unlock signal input unit 43 (S21). Next, the type determination unit 45 commands the door drive unit 41 to open the automatic door 10 (S22). The open / close determination unit 44 determines whether or not the automatic door 10 has been opened when the automatic door 10 is driven by the door drive unit 41 (S23).

When it is determined in step S23 that the automatic door 10 has not opened (S23: NO), the electric lock 30 is either electric lock B1 or C2, and the type determination unit 45 is in the unlocked state. It is determined whether or not there is (S24). When the type determination unit 45 determines that the unlocking signal is in the ON state (S24: YES), it determines that it is the electric lock C2 (S25), and ends the process. When it is determined in step S24 that the unlocking signal is not in the ON state (S24: NO), the type determination unit 45 determines that the lock is B1 (S25), and ends the process.

When it is determined in step S23 that the automatic door 10 has been opened (S23: YES), the electric lock 30 is one of the electric locks A, B2, and C1, and the type determination unit 45 is connected to the electric lock control unit 42. On the other hand, the voltage applied to the electric lock 30 is instructed to be 30 V, and the state of the unlock signal in the lock / unlock signal input unit 43 is confirmed (S27). The type determination unit 45 determines whether or not the state of the confirmed unlocking signal has changed from step S21 to step S27 (S28). If the determination result is that the unlock signal state has changed in step S28 (S28: YES), the type determination unit 45 determines that the lock is B2 (S29), and ends the process.

When the determination result is that the state of the unlock signal has not changed in step S28 (S28: NO), the type determination unit 45 determines whether or not the unlock signal is always OFF (S30). When the type determination unit 45 determines in step S30 that the unlock signal is always OFF (S30: YES), it determines that it is the electric lock A (S31), and ends the process. If the type determination unit 45 determines in step S30 that the unlock signal is not always OFF (S30: NO), and if it is the electric lock C1 (S32), the type determination unit 45 ends the process.

The door controller 40 can determine the types of the electric locks A, B1, B2, C1 and C2 from step S21 to step S32 shown in FIG. 6, which is a processing procedure different from that of FIG. In the type determination process shown in FIG. 6, the type determination unit 45 is either an unlock type when no voltage is applied or a lock type when no voltage is applied by the opening operation of the automatic door 10. Determine if there is any. Further, in the discrimination between the electric locks B1 and C2, in the case of the electric lock C2, it is utilized that the lock / unlock signal input terminal 43a of the lock / unlock signal input unit 43 is in a short-circuited state.

Further, the type determination unit 45 determines the electric lock B2 by using the change in the locking / unlocking signal by setting the voltage applied to the electric lock 30 to 30V. Further, the type discriminating unit 45 can discriminate between the electric locks A and C1 by determining whether or not the unlocking signal is always in the OFF state.

(Modification example)
7 (a) to 7 (c) are schematic views showing the connection between the electric lock 30 and the door controller 40 according to the modified example. FIG. 7A shows the connection between the electric lock A and the door controller 40, FIG. 7B shows the connection between the electric locks B1 and B2 and the door controller 40, and FIG. 7C shows the electric locks C1 and C2. It represents the connection with the door controller 40.

The electric lock A shown in FIG. 7A is connected by a connection cable A so that the lock / unlock signal input terminal 43a in the lock / unlock signal input unit 43 of the door controller 40 is in an open state. In the connection cable A, the terminal of the connector c corresponding to the lock / unlock signal input terminal 43a in the lock / unlock signal input unit 43 is in an open state. The connector b of the connection cable A is a female type and is connected to the connector a (male type) on the electric lock A side. Further, the connector c of the connection cable A is a male type, and is connected to the connector d (female type) on the door controller 40 side. The electric locks B1 and B2 shown in FIG. 7B are connected by a connection cable B so that the lock / unlock signal input terminal 43a is connected to the lock / unlock output on the electric lock side. The connector b of the connection cable B is a female type, and is connected to the connectors a (male type) on the electric locks B1 and B2 side. Further, the connector c of the connection cable B is a male type and is connected to the connector d (female type) on the door controller 40 side.

The electric locks C1 and C2 shown in FIG. 7C are connected by a connection cable C so that the lock / unlock signal input terminal in the lock / unlock signal input unit 43 is short-circuited. In the connection cable C, the terminal of the connector c corresponding to the lock / unlock signal input terminal in the lock / unlock signal input unit 43 is in a short-circuited state. The connector b of the connection cable C is a male type, and is connected to the connectors a (female type) on the electric locks C1 and C2 sides. The connector c of the connection cable C is a male type and is connected to the connector d (female type) on the door controller 40 side. It is assumed that the connection cable 60 is the connection cable A for the electric lock A, the connection cable B for the electric locks B1 and B2, and the connection cable C for the electric locks C1 and C2.

In the connection relationship between the electric lock 30 and the door controller 40 according to the modified example, the connection cables A, B, and C have different types. In the discrimination between the electric lock A and the electric locks C1 and C2, the lock / unlock signal input terminal 43a of the lock / unlock signal input unit 43 is determined by the connection cable A and the connection cable C shown in FIGS. 7 (a) and 7 (c). Is used to be in a short-circuited state or an open state. As a result, the type determination unit 45 can determine the type of the two types of electric locks 30 that do not output the lock / unlock signal without driving the automatic door 10. In the connection cable A, the female connector b is connected to the connector a (male type) on the electric lock A side, and the lock / unlock signal input terminal 43a is opened. On the other hand, in the connection cable C, the male connector b is connected to the connectors a (female type) on the electric locks C1 and C2 sides, and the lock / unlock signal input terminal 43a is short-circuited.

Since the connector b of the connection cable A is a female type, the electric locks C1 and C2 are not accidentally connected to the door controller 40 by the connection cable A. Similarly, since the connector b of the connection cable C is a male type, the electric lock A is not accidentally connected to the door controller 40 by the connection cable C.
