- the light projecting means and the light receiving means may be an activation sensor for controlling the opening and closing of the door panel of the automatic door device.
- the automatic door device when an open door panel is closed, the automatic door device can be used as an auxiliary sensor for determining whether or not a person or an object is present in a moving area of the door panel.
- the light projecting control unit causes the light projecting unit to stop projecting light, and then starts projecting light.
- the light projecting unit In the absence of a person or an object, the light projecting unit is in a light reception signal state when the light projecting unit is in the light projection stop state, and the light receiving unit is not receiving the light. Is determined to be normal when the light receiving means is in a light receiving signal state when the light receiving means is receiving the light in the light projection start state, and is determined to be abnormal otherwise. Means determine.
- the light receiving means As an abnormality of the light receiving means, there is a case where the light receiving signal state is the same as when light is received even though the light from the light projecting means is received. Therefore, it can be seen that the above-described abnormality does not occur in the light receiving means if the light receiving means is in the same light reception signal state as when the light receiving means is not receiving light with the light projecting means stopped. Moreover, there is non-light projection as an abnormality of the light projection means. As described above, if there is no abnormality in the light receiving means, the light projecting means starts projecting light, and if the light receiving means is in the same light reception signal state as when the light receiving means is receiving light, then the light projecting means is abnormal. You can see that they are not.
- the light projecting control means controls the light projecting means and the determination means. Judgment can be made.

- the passing area is in the moving area of the door panel.
- An activation sensor having a detection area for opening / closing control of the door panel is provided inside and outside of the movement area. Despite the detection state of the activation sensor changing in time series within a predetermined time, for example, a person or object is detected by the activation sensor on the indoor side of the automatic door device, and then the person or object is detected on the outdoor side. Although the object is detected by the activation sensor!
- the light projecting control means controls the light projecting means and the judgment means Judgment can be made.
- the judgment means Judgment can be made. The same applies when the person or object is detected by the activation sensor on the outdoor side and then the person or object is detected by the activation sensor on the indoor side, but the auxiliary sensor does not detect the person or object. is there.
- the auxiliary sensor determines whether the vehicle has passed the passage area. If the auxiliary sensor is determined to be abnormal, the person or object is When it is determined by the activation sensor that the vehicle has passed the passage area, the door panel can be closed at a lower speed than the normal closing speed. In addition, when the activation sensor determines that the person or object does not pass through the passage area, the door panel is kept open.

- a door opening 6 is formed between a wall 2 that partitions the inside and outside of a building and a fixed wall 4. ing. A person passes through door opening 6 and goes inside and outside the building. In order to open and close the door opening 6, the door panel 8 slides in the width direction of the door opening 6. As the door panel, use the force S that shows one-sided sliding with one door panel sliding, and double-sided one that opens and closes the door opening 6 by sliding two door panels in opposite directions. You can also use a swinging door none.
- an indoor start sensor 12 is provided on the indoor side of the seamless 10 above the door opening 6.
- the indoor side activation sensor 12 is an optical type, and the indoor side detection area 14 is formed from the indoor side activation sensor 12 toward the indoor floor near the door opening 6.
- the indoor start sensor 12 has a plurality of light projectors and a plurality of light receivers respectively corresponding to the light projectors, and projects light, for example, infrared rays, onto each small spot 14a on the floor as shown in FIG. The reflected light from each small spot is received by the corresponding light receiver.
- an outdoor side activation sensor 16 is similarly provided on the outdoor side of the seamless 10, and an outdoor side detection area 18 is formed on the outdoor side in the vicinity of the door opening 6.
- the outdoor start sensor 16 can also project infrared rays from multiple projectors toward multiple small spots 18a on the floor on the outdoor side, and receive the reflected light from each small spot 18a with a receiver corresponding to each projector. It is configured as follows. Therefore, in the same manner as described above, whether or not a person or an object exists in the outdoor side detection area 18 is detected based on whether or not the light is received by the light receiver.
- struts for example, verticals 20 and 22, respectively, are installed facing each other.
- a light projecting means of the auxiliary sensor 24 of the phototube type, for example, a light projector 26 is installed in the vertical 20.
- a light receiving means of the auxiliary sensor for example, a light receiver 28 is installed in the vertical 22 .
- the light projector 26 always projects light, for example, infrared light, to the light receiver 28 through the auxiliary detection area 30 as shown in FIG. If there is no person in the auxiliary detection area 30, infrared light is received by the light receiver 28, and if there is a person or object, the infrared light is blocked by the person or object and not received by the light receiver 28! /. Whether or not a person or an object exists is detected based on the presence or absence of light received by the light receiver 28. In FIG. 2, the sizes of the projector 26 and the light receiver 28 are drawn with a considerable exaggeration.
- the control means for example, the door controller 32 controls the door panel 8.
- the door controller 32 is installed in the blind 10.
- the door controller 32 is connected to the indoor activation sensor 12 and the outdoor activation sensor 16 via a bus, for example, a CAN (Controller Area Network) bus 34.
- the auxiliary sensor 24 is directly connected to the door controller 32.
- the door controller 32 controls the driving means, for example, the motor 36. Then, the door panel 8 is slid to open the door opening 6.
- the auxiliary sensor 24 detects the human body and the activation sensor on the opposite side does not detect the human or object. Then, the door panel 8 is slid in the opposite direction to close the door opening 6.
- the door controller 32 is also connected to the electric lock controller 38 via the CAN bus 34.
- the electric lock controller 38 is for controlling an electric lock that fixes the door panel 8 so that it cannot move in a state where the door panel 8 closes the door opening 6.
- the electric lock controller 38 excites the solenoid 40 that drives the electric lock, and locks the door panel 8 with the electric lock.
- a display device 42 is also connected to the CAN bus 34 to display the operation status of the door controller 32, indoor start sensor 12, outdoor start sensor 16, and electric lock controller 38, and to set operation parameters to these. Or
- the light projector 26 of the auxiliary sensor 24 fails and no light is emitted while the light receiver 28 is in a normal state, the light receiver 28 does not receive light. As a result, it is erroneously detected that a person or object exists even though the person or object does not exist in the auxiliary detection area 30. In this case, although the person or object has finished passing through the door opening 6, the door opening 6 remains open, and the shielding performance is impaired. In addition, when the projector 26 is in a normal state, the receiver 28 breaks down, and the receiver 28 receives the same received light signal as when the person or object is present in the auxiliary detection area 30.
- the door controller 32 performs an inspection as to whether or not there is an abnormality in the auxiliary sensor 24 as follows.
- step S2 it is determined whether the indoor side activation sensor 12 or the outdoor side activation sensor 16 is detecting a person or an object (step S2). If the answer is no, step S2 is repeated until yes. When the answer to the determination in step S2 is yes, the door panel 8 is opened (step S4). This is followed by a sensor check
- sensor check A As shown in FIG. 5, after the indoor start sensor 12 detects a person or object in step S2, or in step S2, the outdoor start sensor 16 detects a person or object. After that, the first set time (for example, the time required for a person or object to pass through the indoor detection area 14 and reach the auxiliary detection area 30 or the outdoor detection area 18 through the auxiliary detection area 30) It is determined whether the auxiliary sensor 24 has detected a person or object within the time required to reach (step S8). If the answer to this determination is yes, the auxiliary sensor 24 can be regarded as normal, and the processing of this sensor check A is terminated.
- the first set time for example, the time required for a person or object to pass through the indoor detection area 14 and reach the auxiliary detection area 30 or the outdoor detection area 18 through the auxiliary detection area 30
- the auxiliary sensor 24 It is determined whether the auxiliary sensor 24 has detected a person or object within the time required to reach (step S8). If the answer to this determination is yes, the auxiliary sensor 24 can be regarded as
- step S8 If the answer to the determination in step S8 is no, if the indoor activation sensor 12 detects a person or an object in step S2, the indoor activation sensor 12 detects the person or the object. Within the set time, the force at which the outdoor side start sensor 16 detects a person or an object, or the outdoor side start sensor 16 in step S2 It is determined whether the indoor start sensor 12 has detected a person or an object within the second set time after the side start sensor 16 has detected a person or an object (step S10).
- the second set time is, for example, the time required for a person or object to pass from the indoor detection area 14 through the auxiliary detection area 30 to reach the outdoor detection area 18, and from the outdoor detection area 18 to assist. This is the time required to pass through the detection area 30 and reach the indoor detection area 14.
- step S10 If the answer to the determination in step S10 is yes, for example, a person or object is detected in the indoor detection area 14, and then a person or object is detected in the outdoor detection area 18, an auxiliary Sensor 24 is not detecting a person or object. Or, conversely, a person or object is detected in the outdoor detection area 18 and then a person or object is detected in the indoor detection area 14! /, While the auxiliary sensor 24 detects a person or object. ! /, What! / That is, the detection state of the indoor start sensor 12 and the outdoor start sensor 16 changes in time series! /, But the auxiliary sensor 24 detects a person or object! / It will be. Therefore, it is determined that there is an abnormality in the auxiliary sensor 24 (step S12). Sensor check A is then completed.
- step S14 it is determined whether an abnormality is determined in sensor check A (step S14). If the answer to this determination is yes, a flag is set to instruct the auxiliary sensor to be rechecked if it is determined that there was an abnormality when the door was opened or closed the last time (step S16). . If no previous abnormality is determined in step S16, it is stored that the abnormality was made this time as preparation for the next processing of step S16.
- step S14 If the answer to step S14 is no, or following step S16, it is determined whether the indoor start sensor 12, the outdoor start sensor 16 or the auxiliary sensor 24 detects a human body. (Step S18). If the answer is yes, step S18 is repeated. When the answer to this determination is no, a person or object whose indoor start sensor 12, outdoor start sensor 16 and auxiliary sensor 24 are not detecting any person or object It is judged that the outdoor detection area 18 also passed from the indoor detection area 14 via the auxiliary detection area 30, and conversely, the indoor detection area 14 also passed from the outdoor detection area 18 via the auxiliary detection area 30. .
- step S20 it is determined whether the recheck flag is set before the force for closing the door panel 8 (step S20). If the answer to this determination is no, it can be determined that rechecking of the auxiliary sensor 24 is unnecessary, so the flag is reset and the door panel 8 is normally closed (step S22). Following this step S22, step S2 is executed again.
- step S20 If the answer to the determination in step S20 is yes, that is, if the sensor check A is determined to be abnormal twice in succession, sensor check B is performed (step S24).
- step S26 the light projection from the light projector 26 is stopped.
- step S28 it is determined whether the light projection stop can be confirmed by the light receiver 28, that is, whether the light receiver 28 generates a signal generated when the light from the light projector 26 is received. If the answer to this determination is no, it is determined that the light receiving device 28 is not normal because the light receiving device 28 is not receiving light but is in the same light receiving signal state as that receiving light. Therefore, it is determined that the auxiliary sensor is abnormal (step S30).
- step S28 If the answer to the determination in step S28 is yes, the light receiver 28 can be regarded as normal, and then light projection is started from the light projector 26 (step S32). Then, it is judged whether or not the light receiving device 28 can confirm the force at which a signal based on the light projection from the light projector 26 is generated, that is, the light projection start can be confirmed by the light receiver 28 (step S34). If the answer to this determination is yes, the projector 26 can be regarded as normal, and the sensor check B process is terminated. If the answer to the determination in step S34 is no, it can be determined that there is an abnormality in the projector 26 that does not normally project light from the projector 26. Accordingly, step S30 is executed, and as a result, the auxiliary sensor 24 is determined to be abnormal, and the sensor check B is terminated.
- step S36 it is determined whether or not the sensor check B determines that there is an abnormality as shown in FIG. 4 (step S36). If the answer to this determination is no, that is, if it is normal, step S24 is executed. As a result, the recheck flag force S is reset, and the normal door opening / closing operation is performed. Thereafter, the process is executed again from step S2.
- step S36 If the answer to step S36 is no, that is, if it is determined that there is an abnormality in sensor check B, an abnormality flag is set and an error is displayed on the display device 42 (step S38). Thereafter, an abnormality handling process is executed (step S40). The auxiliary sensor 24 is repaired based on this error indication. However, due to the period until repairs are made, an emergency response process will be performed.
- step S42 it is first determined whether the indoor side activation sensor 12 or the outdoor side activation sensor 16 is detecting a person or an object. That is, it is determined whether a person or an object exists in the indoor detection area 14 or the outdoor detection area 18. If the answer is no, repeat step S42. If the answer to step S42 is yes, the door is opened (step S44).
- step S46 it is determined whether either the indoor side start sensor 12 or the outdoor side start sensor 16 is detecting a person or an object. If the answer to this determination is yes, step S44 is performed. Will be executed again.
- step S46 it is determined whether 16 has detected a person or an object in time series (step S48). That is, at first, a person or an object is detected by the indoor side activation sensor 12, and it is determined whether a person or an object is detected by the outdoor side activation sensor 14 after a predetermined time has elapsed. Conversely, a person or object is initially detected by the outdoor side activation sensor 16, and it is determined whether a person or object has been detected by the indoor side activation sensor 12 after a predetermined time has elapsed.
- the door panel 8 is closed at a low speed. That is, the door panel 8 is closed at a speed slower than the normal closing speed of the door panel 8 (step S50).
- the reason for closing at low speed is that there is an abnormality in the auxiliary sensor 24, and even if there is a person or object near the door opening 6, it cannot be detected. .
- step S48 If the answer to the determination in step S48 is no, a person or object is detected, for example, indoors. It is determined that the force S in area 14 has progressed to the opposite side of door opening 6 without proceeding to door opening 6 side. Alternatively, it is determined that the human body has progressed to the opposite side of the door opening 6 without proceeding to the door opening 6 side due to the force S existing in the outdoor side detection area 18. Accordingly, the door panel 8 remains open (step S52). This is because it is unclear whether or not a person or object has passed, so that the door panel is kept open to ensure safety. After the execution of step S50 or S52, the process is executed again from step S42. Therefore, after the auxiliary sensor 24 is determined to be abnormal, the auxiliary sensor 30 is not related to the door opening / closing control, and is performed by the start sensors 12 and 16.
- the auxiliary sensor 24 is directly connected to the door controller 32.
- the auxiliary sensor 24 is also connected to the CAN bus 34, and the door controller is connected via the CAN bus 32. The detection result of the human body can be transmitted to 32.
- sensor check B is performed to determine whether there is an abnormality in auxiliary sensor 24 accurately. This is because in Sensor Check B, since the projector 26 stops and starts projecting light, a large current flows through the projector each time the projection is stopped and started. Therefore, if sensor check B is performed each time before the door panel 8 is closed, the life of the projector 26 may be shortened. Therefore, the sensor check A performs a check that does not stop or start the light projection to the projector 26, and if it is assumed that the auxiliary sensor 24 is abnormal, the sensor check B performs a full-scale check and the auxiliary sensor 24 This prevents the life of 24 from becoming shorter. If the life of the auxiliary sensor 24 does not matter, you can remove steps S6, S14, S16, and S22 and check the auxiliary sensor 24 based on sensor check B! / ,.
- the sensor check B is performed after step S20.
- the auxiliary sensor 24 is diagnosed as being normal before the door panel 8 starts the closing operation. This is because the auxiliary sensor is checked immediately before the door panel 8 is closed to reduce the probability that the human body will be pinched by mistake.
- it is not always necessary to perform the operation before the door panel 8 is closed. For example, it can be performed immediately after the automatic door device is turned on, or can be determined in advance from when the door panel 8 is opened or closed. Over the time Sensor check B can be performed when channel 8 is not being opened or closed.
- the force that sensor check B is performed when sensor check A is judged to be abnormal twice in succession If there is a person or object that has stopped for a while or longer, even if the auxiliary sensor 24 is normal, it is judged as abnormal by sensor check A, so only perform sensor check A once. This is because the auxiliary sensor 24 may not be abnormal. However, when the number of times that the sensor check A is judged to be abnormal is more than twice, the sensor check B can be fi.
- the abnormality handling process of step S40 is performed. Even if the auxiliary sensor 24 is out of order, after a person or object passes through the door opening 6, the shielding property, which is one of the features of the automatic door device, is ensured with consideration for safety. Because. However, even if the shielding performance is sacrificed, the door opening 6 can be left open after performing the process of step S38 if more safety is desired.
- the activation sensors 12 and 16 are optical forces that are not limited to this, and various known activation sensors such as an ultrasonic type and a distance measuring type are used. That's the power S.
- the auxiliary sensor 24 is not limited to the photoelectric tube type, and may be an infrared reflection type like the start sensor 12 and may be provided immediately.
