BACKGROUND OF THE INVENTION
The present invention relates to an automatic sliding door device for automatically opening and closing a sliding door door installed in a residence or the like.
[0002]
[Prior art]
In recent years, various automatic sliding door devices have been provided in order to automate the opening and closing of sliding doors installed in a residence or the like. The main activation methods of these automatic sliding door devices are the power assist method and the remote control operation method. In order to meet the various needs of consumers, automatic sliding doors that automatically open and close the sliding door when a human body is detected Sliding doors with interior equipment are provided.
[0003]
A conventional sliding door equipped with the automatic sliding door device will be described based on the embodiment shown in FIG. FIG. 5: has shown the front view of the house interior automatic sliding door, and is the structure which suspended the sliding door 2 on the rail 1 with a built-in drive motor provided above the house opening part. A starting sensor 3 is attached to the sliding door 2, and a control device 4 is built in the rail 1 with a built-in driving motor. Since the start sensor 3 and the control device 4 are connected by an internal dedicated cord, the sliding door 2 automatically moves on the drive motor built-in rail 1 when the start sensor 3 senses a human body. Then, the sliding door 2 is opened and closed. As the activation sensor 3, a distance measuring sensor is used, and a reaction is made by holding a hand or the like over the sensor unit.
[0004]
[Problems to be solved by the invention]
However, there are several problems with the conventional technology as described above. First, as a challenge at the production stage, it is necessary to produce sliding doors exclusively for automatic sliding doors, so in order to respond to user requests, it is necessary to prepare dedicated automatic sliding doors with many assortments. Can be mentioned. Even at the construction stage, when the sliding door is suspended, a dedicated cord for connecting the activation sensor and the control device is inserted into the sliding door and it is necessary to connect the cord, so that it takes time for the construction. In addition, the activation sensor built in the sliding door moves with the opening and closing of the sliding door, whereas the control device is fixed and does not move, so there is a risk of breaking the dedicated cord that connects them. There is also. Furthermore, with regard to human body detection, the conventional activation sensor activates the sliding door immediately after the human body is detected by the sensor. Therefore, depending on the layout of the house and the arrangement of the sliding doors, it detects the passersby and opens and closes the sliding door unnecessarily. The point was an issue.
[0005]
The present invention has been made in view of the above points, and is an unnecessary opening and closing that can be manufactured using a conventional sliding door without installing a dedicated cord and without newly manufacturing a dedicated sliding door. It is an object of the present invention to provide an automatic sliding door device having a function of preventing the above.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the automatic sliding door according to the present invention has a remote control signal receiving unit for receiving a remote control signal generated by the operation remote controller and outputting a door opening signal to the control unit of the automatic sliding door device, and ranging. It includes a human body detection unit by the sensor, and a remote control signal transmitting unit for transmitting a remote control signal for outputting the door opening signal to the control unit when the human body detection unit has detected the human body to the remote control signal receiving unit, the remote control signal receiver The automatic sliding door device is characterized in that the unit is used for both reception of a remote control signal emitted from an operation remote controller and reception of a remote control signal emitted from a remote control signal transmission unit . Accordingly, not only when the operation remote controller is used, but also when the human body detection unit detects a human body, a remote control signal for causing the control unit to output a door opening signal is transmitted to the remote control reception unit.
[0007]
In addition, when the remote control signal emitted from the remote control signal transmitter is infrared, it is reflected once on the floor and received by the remote control signal receiver, so that even if the remote control method is not radio wave type but infrared type, remote control signal transmission And the remote control signal receiving unit need not be in a positional relationship where the remote control signal can be directly received.
[0008]
In addition, when the human body detection is performed only for a short time by setting the time when the remote control signal is transmitted from the remote control signal transmission unit as the time when the human body detection by the human body detection unit is continuously performed for a predetermined standby time or longer. Since no remote control signal is transmitted, it is possible to prevent malfunction caused by detection of a passerby who does not intend to open the sliding door.
[0009]
Also, by making the standby time adjustable, the user can set the time from human body detection to remote control signal transmission for his own convenience.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. FIG. 1 shows a schematic diagram of an automatic sliding door using an automatic sliding door device as an example in the embodiment of the present invention. A mover 5 made of a permanent magnet is fixed to the upper end of the sliding door 2, and a stator 6 made of an armature coil is fixed inside the upper frame 7 so as to face the mover 5. The stator 6 is connected to a motor control unit 8 that is also housed in the upper frame 7 via a lead wire. The motor control unit 8 is provided with a remote control signal receiving unit 9. When the remote control signal 20 is received from the operation remote control 10, the remote control signal receiving unit 9 outputs a door opening signal to the motor control unit 8. A child remote controller signal receiving unit 9a is provided on the opposite side of the sliding door 2 of the motor control unit 8, and the sliding door 2 can be opened and closed using the operation remote controller 10 from the opposite side. Upon receipt of the opening signal, the motor control unit 8 controls the excitation of the armature coil and uses the attractive and repulsive force generated between the stator 6 by the armature coil and the mover 5 between the permanent magnets, and the sliding door 2. Open and close. In this example, the linear motor method using the stator 6 and the mover 5 is adopted as the drive method as described above, but another drive method may be adopted. As for the remote control method, this example is an infrared type, but it may be a radio wave type. However, in the case of the radio wave type, it is not necessary to provide the child remote control signal receiver 9a.
[0011]
The configuration up to the above is substantially the same as the remote control operation type automatic sliding door device that has been conventionally used, but in this example, it is further above the upper frame 7 and at the front and back positions with respect to the sliding door 2. A pair of distance measuring sensor built-in type remote controller 11 is provided. The distance sensor built-in remote controller 11 has a human body detector 12 and a remote controller signal transmitter 13, and the human body detector 12 uses a distance sensor 14 to detect a human body or the like. Here, the distance measuring sensor 14 is a sensor that detects a human body or the like by the light projecting element 14a and the light receiving unit 14b shown in FIG. 4 and measures the distance to the detected body.
[0012]
As shown in FIG. 2, the distance measuring sensor built-in remote controller 11 has a predetermined waiting time after the distance measuring sensor 14 of the human body detecting unit 12 detects the detected object within the specified inspection distance, that is, within the distance measuring sensor detection area 14a. The remote control signal 20 is transmitted from the remote control signal transmission unit 13 provided in the driver 16 only when time has passed and detection is continuing. Further, the remote controller 11 with built-in distance sensor repeats the transmission of the remote control signal 20 at a constant remote control transmission period as long as the object to be detected is detected in the distance sensor detection area 14a. Even when it occurs, the non-operation of the sliding door 2 is prevented. Since the inspection distance can be set freely, the remote control signal 20 can be prevented from being transmitted when a pet, a four-year-old infant, or the like is detected. The standby time is set by a remote control transmission wait setting variable resistor 15 provided in the control circuit 16.
[0013]
FIG. 3 more specifically shows the timing of the remote control signal 20 transmission. When the distance sensor 14 detects the object to be detected, a distance sensor signal is output, and the remote control signal 20 is transmitted by the output. In this example, the distance sensor signal is first output and then 0.5. The remote control signal 20 is not transmitted until the standby time A of 2 seconds elapses. If the distance measurement sensor signal is continuously output during the standby time A, the remote control signal 20 is transmitted at the end of the standby time A, and the distance measurement sensor signal is output before the standby time A elapses. If it has been completed, the remote control signal 20 is not transmitted. By doing in this way, the malfunction that the sliding door 2 opens by detection of a passerby etc. is prevented. In addition, in order to prevent the sliding door 2 from malfunctioning due to a lack of remote control reception, the above transmission is performed twice at a time.
[0014]
In order to further prevent the sliding door 2 from malfunctioning, the remote control signal 20 is repeatedly transmitted at the remote control transmission cycle B of 0.5 seconds while the distance measuring sensor signal is continuously output. However, with regard to the transmission of the remote control signal 20 for the second time or later, if the distance measurement sensor signal is continuously output for 0.2 seconds or more after the transmission of the previous remote control signal 20 is completed, the remote control transmission cycle B is elapsed. The remote control signal 20 is transmitted even if the distance measuring sensor signal has not been output. On the contrary, if the distance measurement sensor signal is not output 0.2 seconds before the end of the transmission of the previous remote control signal 20, the remote control signal 20 is not transmitted.
[0015]
In this example, the waiting time is set to 0.5 seconds as described above. However, the user can adjust the waiting time in the range of 0 to 3 seconds in increments of 0.5 seconds (ie, 0, The waiting time can be adjusted (in 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 seconds). Therefore, for example, by setting the standby time to 0 seconds, it is possible to set the remote control signal 20 to be transmitted when the distance measuring sensor 14 detects the detected object.
[0016]
The remote control signal 20 transmitted from the remote controller 11 with built-in distance measuring sensor is received by the remote control signal receiving unit 9 provided in the motor control unit 8 or the child remote control signal receiving unit 9a to output a door opening signal. The above procedure is similar to the procedure for opening and closing the sliding door 2 by the operation remote controller 10, and the remote control signal receiving unit 9 and the child remote control signal receiving unit 9 a use the operation remote control 10 and use the human body detection unit 12. Also used for reception.
[0017]
However, when the infrared type is adopted as the remote control method as in this example, the remote control signal 20 is directly transmitted from the remote control 11 incorporating the distance measuring sensor to the remote control signal receiving unit 9 and the child remote control signal receiving unit 9a. Since it is difficult due to the positional relationship, it is reflected after being reflected on the floor once.
[0018]
【The invention's effect】
The following effects can be obtained by the automatic sliding door device of the present invention. First, at the manufacturing stage, the automatic sliding door device of the present invention can be obtained by simply adding the remote controller with built-in distance measuring sensor to the automatic sliding door device using the operation remote controller already provided. Therefore, it is possible to easily cope with a plan change such as addition of a user sensor function. In addition, since the door opening signal based on human body detection is transmitted wirelessly, it is no longer necessary to install a dedicated cord, which was necessary in the past, so that construction work can be done easily. In addition, there is no worry that the dedicated cord will break when the sliding door opens and closes. The detection of the human body also uses a distance sensor to prevent unnecessary opening and closing of the sliding door by detection of pets and infants, and by detecting the passersby by appropriately adjusting the time from detection to motor activation. Unnecessary opening and closing of sliding doors can be prevented. Furthermore, the remote control signal receiving unit receives both the remote control signal from the remote control with built-in distance sensor and the remote control signal from the operation remote control, and it may open and close the sliding door by detecting itself by approaching, The sliding door may be opened and closed by using an operation remote controller from a distance. Therefore, the opening / closing method of the sliding door according to convenience can be selected.
[0019]
When the infrared type is adopted as the remote control method, it is used even if it is installed above the sliding door so that the remote control signal transmitter and remote control signal receiver both face the floor by using the floor reflection of the remote control signal. can do.
