Description

  The present invention relates to an automatic door control system that performs open / close control of an automatic door, and more particularly to an automatic door control system that improves the reliability of an automatic door closing control operation.

  2. Description of the Related Art Conventionally, as an automatic door control system that performs opening / closing control of an automatic door, an automatic door device including an active infrared sensor is known (see, for example, Patent Document 1). The infrared sensor includes a light projecting element and a light receiving element, projects infrared light from the light projecting element into a predetermined area, and receives the reflected light by the light receiving element. When a person enters the area, the infrared light receiving state of the light receiving element changes, whereby the sensor recognizes that the person has approached the automatic door. With this recognition, the sensor transmits a detection signal to the door opening / closing mechanism, and activates the drive source (drive motor) of the automatic door to perform the door opening operation. On the other hand, when there are no more people in the area, the light receiving state of the light receiving element returns to the original state, the detection signal from the sensor is released, and the door is closed by driving the drive source. .

  Some sensors of this type have a static detection function. With this still detection function, when an object such as a human body enters the area and the stationary state in the area of the object continues for a predetermined time, that is, the infrared light receiving state in the light receiving element has once changed. After that, if the light receiving state does not change even after a predetermined time has elapsed, the function of forcibly canceling the transmission of the detection signal and closing the door by driving the drive source is performed. This function is effective in avoiding a situation in which the door is kept open for a long period of time, for example, when a mat placed on the floor in the area is displaced.

  In addition, when the automatic door faces the outdoors and a beam-type auxiliary human body detection sensor is installed on the outdoor side to detect a person who has stopped near the automatic door, the auxiliary human body detection sensor is used. If dust or snow adheres to the light part or the light receiving part, the light receiving part may not receive the projection beam and continue to output the human body detection signal, and the automatic door may remain open without closing and moving. Under such circumstances, an automatic door opening / closing control device that closes the automatic door at a low speed has also been proposed (see, for example, Patent Document 2).

  However, when a person is actually stopped near the automatic door, it is not always desirable to start closing the automatic door before the stopped person notices even at a low speed.

In view of this, an automatic door auto-announcement device has also been proposed that alerts nearby passersby when the automatic door is closed (see, for example, Patent Document 3). Alternatively, an automatic door sensor equipped with a stationary detection function as described above, and an automatic door sensor that uses a voice warning when closing the automatic door at a low speed by the function, and an automatic door device equipped with the sensor are also proposed. (For example, see Patent Document 4).

  However, in the related arts such as Patent Document 3 and Patent Document 4 described above, when a person is actually stopped near the automatic door, such a person is informed that the automatic door has begun to close due to a voice warning. Although it is possible to know, it is not always possible to immediately leave the vicinity of the automatic door. For some reason, it may be difficult to leave the vicinity of the automatic door, or it may take a considerable amount of time to leave.

  In view of such problems of the prior art, the object of the present invention is to provide a voice warning prior to the start of automatic door closing when a person is stopped near the automatic door, It is to provide an automatic door control system in which the reliability of the closing control operation and the like are greatly improved by performing the actual closing operation after confirming that the vehicle is away from the vicinity.

  In order to achieve the above object, an automatic door control system according to the present invention is an automatic door control system that controls opening and closing of an automatic door, and detects the presence or absence of an object existing in the vicinity of the automatic door, and an object is present. A first detector that outputs a first signal, and an output of a door opening signal that commands opening and closing of the automatic door based on the first signal, and a state in which the first signal is output. And a control means for controlling the output of a sound warning signal so as to give a first sound warning for prompting the user to leave the vicinity of the automatic door when it continues for a predetermined time or longer.

  Here, as the message for the first voice warning, for example, a voice such as “The door closes. Do not stop at this place.” Or “This area is dangerous. Do not stop.” However, the content is not limited to this.

  According to the automatic door control system having such a configuration, since a voice warning is given when a person is stopped near the automatic door, it is possible to alert the person who has stopped. Then, it is expected that a person who has stopped in the vicinity of the automatic door without being aware of it will notice it by an audio warning and will immediately leave the vicinity of the automatic door. Thereby, the reliability of the closing control operation is improved.

  Further, in the automatic door control system of the present invention, the control means controls the door to maintain the open state of the automatic door when controlling the output of the sound warning signal so as to perform the first sound warning. The output of the open signal may be controlled.

  According to the automatic door control system having such a configuration, even if an audio warning is given, the automatic door does not immediately start to close. As a result, even if it is difficult for a person who has stopped near the automatic door to leave the automatic door for some reason or it takes a considerable amount of time to leave, there may be a problem. Absent.

  In the automatic door control system according to the present invention, the control means may be in a state where the first signal is output even after the output of the audio warning signal is controlled so as to perform the first audio warning. When the above is continued, the output of the sound warning signal may be controlled so that the first sound warning is performed again.

  According to the automatic door control system configured as described above, when a person has stopped around the automatic door for a long time, the voice warning is repeated every predetermined time. Even if you missed it, you can definitely call attention.

  The automatic door control system of the present invention further includes a second detector that detects an object approaching the automatic door or outputs a second signal when a predetermined operation is performed and transmits the second signal to the control means. The control means controls the output of the door opening signal for instructing opening / closing of the automatic door based on the first signal and the second signal, and performs the first sound warning so as to perform the first sound warning. If neither the first signal nor the second signal is output after controlling the output of the signal, the output of the door opening signal may be controlled to close the automatic door.

  According to the automatic door control system having such a configuration, after confirming that no one is stopped near the automatic door after the voice warning, the automatic door starts to close. As a result, the reliability of the closing control operation is further improved, and the automatic door is prevented from being left unnecessarily opened for a long time, so that, for example, loss of the air conditioning surface can be reduced.

  In the automatic door control system of the present invention, the control means generates a sound to start the closing operation of the automatic door before controlling the output of the door opening signal so as to close the automatic door. The output of the voice warning signal may be controlled so as to perform the second voice warning.

  Here, as the second voice warning message, for example, a voice such as “Door closes” or a simple chime sound can be considered, but the message is not limited to this.

  According to the automatic door control system having such a configuration, since an audio warning to that effect is always made before the automatic door starts to close, the reliability of the closing control operation is further improved.

  In the automatic door control system of the present invention, there is further provided a third detector that determines whether or not the automatic door is closed and outputs a third signal when the automatic door is closed to transmit to the control means. And the control means controls the output of the door opening signal for instructing opening / closing of the automatic door based on the first signal, the second signal, and the third signal, and opens the automatic door. If the third signal is output when controlling the output of the door opening signal, the sound is output so that a third sound warning is generated to generate a sound indicating that the automatic door starts opening operation. The output of the warning signal may be controlled.

  Here, as the third voice warning message, for example, a voice such as “Door opens” or a simple chime sound (however, the tone of the second voice warning may be changed. However, the content is not limited to this.

  According to the automatic door control system having such a configuration, a sound warning to that effect is given before the automatic door starts to open, so that the reliability of the closing control operation is further improved. In addition, since the third voice warning can be performed as necessary in consideration of whether or not the automatic door is completely closed, for example, the automatic door starts to open again in the middle of starting to close. Occasionally, the third voice warning can be omitted to prevent frequent and troublesome voice warnings.

  According to the automatic door control system of the present invention, since a voice warning is given when a person is stopped near the automatic door, the person who is stopped can be alerted. Then, it is expected that a person who has stopped in the vicinity of the automatic door without being particularly conscious notices it by an audio warning and quickly leaves the vicinity of the automatic door. Thereby, the reliability of the closing control operation is improved.

  Embodiments of the present invention will be described below with reference to the drawings.

<Configuration of automatic door control system 1>
FIG. 1 is a block diagram of an automatic door control system 1 according to an embodiment of the present invention. As shown in FIG. 1, the automatic door control system 1 is configured to output an opening command for instructing a door engine controller 3 that drives a door engine 2 such as a motor for opening and closing a sliding door to start opening the door. Automatic door opening / closing by outputting a signal S1 (corresponding to the start input of the door engine controller 3) and an open state maintaining output signal S2 (corresponding to the auxiliary input of the door engine controller 3) for commanding the maintenance of the door open state. It has a function to perform control, and in this respect, it is compatible with commercially available automatic door sensors.

  The automatic door control system 1 detects an auxiliary sensor 11 for detecting an object such as a person standing in the vicinity of the automatic door 5 and an object such as a person approaching the automatic door 5 inside the automatic door 5. A detection sensor A that forms a detection area A12, a door fully-closed detection switch 13a that detects whether the automatic door 5 is fully closed or otherwise, and whether the automatic door 5 is fully open or otherwise detected And a setting switch 14 for performing various settings of the automatic door control system 1 as required, and a signal processing / control circuit 10 for performing these controls.

  Here, the auxiliary sensor 11 includes, for example, a light projecting element that projects near-infrared light and a light-receiving element that directly receives the near-infrared light projected from the light projecting element. An existing photoelectric switch or the like that detects an object when the infrared ray is blocked and cannot receive light may be used, but is not limited thereto.

  The activation sensor 12 includes, for example, a light projecting element that projects near-infrared light, a light-receiving element that receives near-infrared light that is projected from the light projecting element and reflected by the object, and an optical system. An existing AIR type detector that can detect (preferably with a stationary object detection function) may be used, but is not limited thereto. For example, the presence of a person trying to pass through the automatic door 5 may be detected by performing a predetermined operation on a touch switch, a numeric keypad device, or the like.

  Examples of the door full-close detection switch 13a and the door full-open detection switch 13b include a magnet switch. About the door full-closed detection switch 13a, whether or not the automatic door 5 is completely closed can be determined by mounting the automatic door 5 in a position where the automatic door 5 is completely closed and other states. Can be detected. The door full open detection switch 13b is also attached to a position where the conduction state is switched between the state in which the automatic door 5 is completely opened and the other state, thereby detecting whether or not the automatic door 5 is completely opened. can do. However, the switch is not limited to a magnet switch, and other types of switches may be used, or an encoder that can detect the position of the automatic door 5 in the middle of opening and closing is installed continuously or step by step. You may make it detect whether the automatic door 5 is closed based on a result.

  Examples of the setting switch 14 include, but are not limited to, a dip switch and a jumper switch for switching the setting of a plurality of items. For example, a non-volatile storage unit such as a flash memory, and an interface for accessing the external storage to enable rewriting of the stored contents may be used.

  The signal processing / control circuit 10 controls the operation of each of the auxiliary sensor 11 and the activation sensor 12, the detection results of the auxiliary sensor 11 and the activation sensor 12, the detection results of the door full-close detection switch 13 a and the door full-open detection switch 13 b, Based on the setting state by the setting switch 14 and the like, the respective states of the opening command output signal S1 and the opening state maintaining output signal S2 for the door engine controller 3 are switched to ON or OFF. Furthermore, various voice warning output signals S3 are output at appropriate timing as required during automatic door opening / closing control. Details of the output control of the release command output signal S1, the open state maintenance output signal S2, and the voice warning output signal S3 will be described later.

  The door engine controller 3 drives the door engine 2 in accordance with the opening command output signal S1 and the open state maintenance output signal S2 output from the signal processing / control circuit 10. Specifically, when the opening command output signal S1 from the signal processing / control circuit 10 is turned ON, the door engine 2 is driven so that the automatic door 5 is opened, and the open state from the signal processing / control circuit 10 is maintained. While the output signal S2 is ON, the automatic door 5 is kept open. When the opening command output signal S1 and the open state maintenance output signal S2 from the signal processing / control circuit 10 are switched to OFF, the door engine 2 is driven so that the door is closed.

  The voice warning output signal S3 from the automatic door control system 1 is connected to a speaker 15 that can generate artificial voice or the like according to the voice warning output signal S3. However, the present invention is not limited to this. Also, other warning external devices may be combined.

  As for the output from the automatic door control system 1, the output corresponding to the start input of the door engine controller 3 is referred to as “startup output”, and the output corresponding to the auxiliary input of the door engine controller 3 is referred to as “combined output”. Sometimes. In this case, the relationship between the “startup output” and the release command output signal S1 and the relationship between the “combined output” and the open state maintenance output signal S2 are not necessarily limited to one-to-one as shown in FIG.

  For example, some door engine controllers have only a start input and no auxiliary input. In such a case, an output corresponding to the logical sum of the open command output signal and the open state maintenance output signal is output. Alternatively, it may be output as an “activation output” from the automatic door control system 1 and connected to the activation input of the door engine controller.

  In order to obtain such a logical sum output, for example, a simple logic circuit or interface may be provided outside the signal processing / control circuit 10, or the control is performed under the control of the signal processing / control circuit 10. You may do it.

  Further, for example, the setting switch 14 may be used to switch between obtaining such a logical sum output and outputting the one-to-one relationship as shown in FIG. Thereby, it becomes possible to change the output from the automatic door control system 1 to an appropriate one according to the actual model of the door engine controller by an easy operation.

<Installation state of automatic door control system 1>
FIG. 2 is a schematic explanatory diagram of an example of an installation state of the automatic door control system 1. Although the door engine 2 and the door engine controller 3 are not shown in the drawing, they are arranged inside the intangible 4.

  As shown in FIG. 2, with respect to the auxiliary sensor 11, a light projecting element is disposed at one end of the opening where the automatic door 5 is installed, and a light receiving element is disposed at the other end. By blocking the near-infrared beam B11 from the light projecting element to the light receiving element, it is possible to detect the presence of an object such as a person 6 in the vicinity of the automatic door 5.

  The activation sensor 12 is installed slightly obliquely downward (in a direction away from the automatic door 5) to the invisible 4 that supports the upper end of the automatic door 5. By forming the detection area A12 toward the floor surface 8 near the automatic door 5, an object such as a person 6 approaching the automatic door 5 can be detected.

  The door full-close detection switch 13a is attached at a position where the conduction state is switched between the state in which the automatic door 5 is completely closed and the other state. Specifically, the blind contact (connected to the signal processing / control circuit 10) of the magnet switch is attached downward to the blind 4, and the blind contact when the automatic door 5 is fully closed. The door side contact of the magnet switch is attached upward to the upper end of the automatic door 5 or the like that faces the door.

  Further, the door full open detection switch 13b is attached at a position where the conduction state is switched between the state where the automatic door 5 is completely opened and the other state. Specifically, the magnetic contact of the magnet switch (connected to the signal processing / control circuit 10) is attached downward to the seamless 4, and when the automatic door 5 is fully opened, The door side contact of the magnet switch is attached upward at the upper end of the automatic door 5 that is just opposite.

  The speaker 15 may be arranged on the wall surface on one side of the opening where the automatic door 5 is installed, but is not limited to such a position. For example, the speaker 15 is arranged in a place where it cannot be seen by the person 6. Also good.

  The signal processing / control circuit 10 is usually disposed in the interior of the blind 4, etc., and is connected to the activation sensor 12, the auxiliary sensor 11, the door full-close detection switch 13a, the door full-open detection switch 13b, the speaker 15, and the like. .

<Main operations of automatic door control system 1>
FIGS. 3A to 3D are explanatory views showing scenes of the main operation of the automatic door control system 1. FIG. 3A is a standby state, and FIG. 3B is a state where a person 6 approaches the detection area A12. (C) is a figure which shows the state after the person 6 stopped in the automatic door 5 vicinity, (d) is the figure after the person 6 who stopped has passed through the automatic door 5, respectively.

  In the “standby state” as shown in FIG. 3A, neither the auxiliary sensor 11 nor the activation sensor 12 detects an object such as a person, and the door fully closed detection switch 13 a Detecting complete closure.

  Next, as shown in FIG. 3B, when the person 6 approaches the automatic door 5 and enters the detection area A <b> 12, the person 6 is detected by the activation sensor 12. As a result, the signal processing / control circuit 10 performs control to start the opening operation of the automatic door 5, but before that, attention is given to the person 6 by generating a sound indicating that the automatic door 5 starts to open from the speaker 15. Arouse. For example, a sound such as “The door opens” may be generated, but the content is not limited to this.

  In addition, since it is thought that the necessity of the audio | voice warning in this scene is not so high, it is sufficient to sound only a chime sound (for example, "pea"), for example. Such switching may be performed according to the setting state of the setting switch 14.

  Thereafter, as shown in FIG. 3 (c), if the state where the person 6 is stopped in the vicinity of the automatic door 5 continues for a long time, the near-infrared beam B11 of the auxiliary sensor 11 remains cut off and can be detected. . In such a case, the signal processing / control circuit 10 does not perform the operation of forcibly closing the automatic door 5 in principle, but the person 15 who is stopped is moved away from the vicinity of the automatic door 5 from the speaker 15. Arouses attention by generating a sound prompting For example, you may be able to generate a sound such as “Door will close. Do not stop at this place.” Or “This area is dangerous. Do not stop.” Do not mean.

  In this scene, it is considered highly likely that the person 6 who has stopped with a simple warning sound does not understand the meaning, so it is preferable to give a specific voice warning as much as possible. However, the contents of the voice warning may be switched according to the setting state of the setting switch 14.

  As shown in FIG. 3D, when the person 6 who has stopped passes through the automatic door 5, neither the auxiliary sensor 11 nor the activation sensor 12 detects an object such as a person. Therefore, the signal processing / control circuit 10 performs control to start the closing operation of the automatic door 5, but before that, by generating a sound to the effect that the automatic door 5 starts to close from the speaker 15, Call attention to another person 6 who may be at a distance. For example, a sound such as “The door closes” may be generated, but the content is not limited to this.

  In this scene, there is a high possibility that there is no person 6 in the vicinity of the automatic door 5, and it is considered that the need for an audio warning is not so high. For example, a simple chime sound may be generated. However, it is preferable to change the tone color so that it can be distinguished from the case of FIG. Further, such switching may be performed according to the setting state of the setting switch 14, or may be interlocked with similar switching in FIGS. 3B and 3C.

<Schematic flowchart of main operations of automatic door control system 1>
FIG. 4 is a schematic flowchart showing the main operation of the automatic door control system 1. Note that these operations are realized by a control program incorporated in the signal processing / control circuit 10.

  As shown in FIG. 4, it is first determined whether or not an object or the like is detected by the activation sensor 12 (step S101). If not detected, this process is repeated. Such repetition does not necessarily have to be performed continuously. For example, it may be performed at regular time intervals. This is because power consumption can be reduced. If an object or the like is detected in step S101, the process proceeds to step S102.

  When the process proceeds to step S102, it is considered that the person 6 has approached the automatic door 5 and has entered the detection area A12 as shown in FIG. 3B. Therefore, in order to open the automatic door 5, the opening command output signal S1 corresponding to the activation input of the door engine controller 3 is switched to ON (step S102). As a result, the door engine controller 3 starts to drive the door engine 2, and thus the automatic door 5 starts to open. If the automatic door 5 is in the middle of closing, the closing operation is stopped, reversed and started to open.

  Next, it is determined whether or not the automatic door 5 is completely closed by the door fully closed detection switch 13a (step S103), and if it is in the fully closed state, an audio warning that the automatic door 5 starts to open from the speaker 15 By controlling the audio warning output signal S3 so as to perform (notice before door opening starts), attention is drawn to a nearby person 6 (step S104).

  Note that the determination in step S103 is performed because it is bothersome if an audio warning is issued each time the closing operation of the automatic door 5 is interrupted and reversed and starts to open. However, the determination in step S103 is not essential and may be omitted. In addition, the opening command output signal S1 may be switched on in step S102 after, for example, a voice warning.

  After the automatic door 5 starts to open, it is determined whether or not the automatic door 5 is fully opened by the door full open detection switch 13b (step S105). If there is, the process proceeds to step S106. That is, here, the process proceeds to the next process after waiting for the automatic door 5 to reach the fully open state.

  Next, it is determined whether or not an object or the like has been detected by the auxiliary sensor 11 (step S106). If detected, the process proceeds to step S112, and if not detected, the process proceeds to step 107. Further, it is determined whether or not an object or the like is detected by the activation sensor 12 (step S107). If detected, the processing from step S106 is repeated, and if not detected, the process proceeds to step 108.

  When the process proceeds to step S108, for example, as shown in FIG. 3D, the person 6 who has stopped has just passed through the automatic door 5, and there is no other person 6 approaching the automatic door 5. it is conceivable that. However, before actually starting to close the automatic door 5, first, by controlling the sound warning output signal S3 so as to give a sound warning to the effect that the automatic door 5 starts to be closed from the speaker 15 (notice before starting the door closing). The other person 6 who may be at a distance from the automatic door 5 is alerted (step S108).

  Next, it is determined again whether or not an object or the like has been detected by the auxiliary sensor 11 (step S109). If detected, the process proceeds to step S112, and if not detected, the process proceeds to step 110. Further, it is determined whether or not an object or the like is detected by the activation sensor 12 (step S110). If detected, the processing from step S105 is repeated, and if not detected, the process proceeds to step 111.

  If the process proceeds to step S <b> 111, it is considered that no person 6 stops near the automatic door and no other person 6 approaches the automatic door 5. Therefore, the release command output signal S1 is turned off (step S111). As a result, the door engine controller 3 starts driving the door engine 2 and the automatic door 5 starts to close. Thereafter, the process returns to the first step S101.

  When the process proceeds to step S112, first, the open state maintaining output signal S2 is turned ON.

  Next, when the state as shown in FIG. 3C continues, the timer T built in the signal processing / control circuit 10 is started so that the duration time can be measured (step S113). . If the timer T is already counting, it is restarted.

  Then, it is determined based on the count value of the timer T whether or not a predetermined time T1 has elapsed since entering such a state (step S114). If it is determined that the predetermined time T1 has not elapsed, the process proceeds to step S116. Further, it is determined whether or not an object or the like is detected by the auxiliary sensor 11 (step S116), and if it is detected, the processing from step S114 is repeated. If not detected, the open state maintenance output signal S2 is turned OFF. Switching (step S117), and then the process returns to step S106.

  If it is determined in step S114 that the predetermined time T1 has elapsed, for example, as shown in FIG. 3C, it is considered that the state where the person 6 has stopped near the automatic door 5 continues for a long time. By controlling the voice warning output signal S3 so as to give a voice warning (recommendation of movement from the vicinity of the door) that prompts the speaker 15 to move away from the vicinity of the automatic door 5, the person 6 who has stopped near the automatic door 5 is notified. Attention is drawn (step S115).

  After that, the process returns to step S113. For example, as long as the state where the person 6 is stopped in the vicinity of the automatic door 5 continues, a voice warning for prompting the user to leave the vicinity of the automatic door 5 is repeated every predetermined time T1. become. However, such repetition may not be performed, and an upper limit may be set for the number of repetitions. Such processing for repetition may be selected according to the setting state of the setting switch 14.

  It should be noted that the present invention can be implemented in various other forms without departing from the spirit or main features thereof. Therefore, the above-mentioned embodiment is only a mere illustration in all points, and should not be interpreted limitedly. The scope of the present invention is indicated by the claims, and is not restricted by the text of the specification.
