[0025]
FIG. 4 is a flowchart showing the operation of the gate opening / closing system 1 according to the first embodiment. Hereinafter, the operation of this embodiment will be described with reference to the flowchart. As an initial state, the gate 2 is in a “closed” state, and the portable device 6 carried by the user 5 is in a reception standby state. Further, the radio base station 8 of the gate side unit 4 transmits an ID signal unique to the gate side unit 4 and a signal indicating the presence or absence of a delivery output from the post control unit 14 via the antenna 15 (step ST1). When the user 5 is not close to the gate 2 in this state, the gate 2 does not operate at all.
[0026]
For example, when the user 5 carrying the portable device 6 comes close to the gate 2 when returning home (step ST2), a signal output from the wireless base station 8 is received by the portable device 6 (step ST2). ST3) The portable device 6 collates the received ID signal (ID of the gate side unit 4) with the ID unique to the portable device 6 (step ST4), and if not collated (that is, the received ID and the portable device 6). In the case where the correspondence with the ID of the machine 6 cannot be obtained ("mismatch" in step ST4), the process returns to the standby state again (in this case, the gate 2 is closed , so the process in step ST12 is omitted). )
[0027]
When the received ID matches the ID of the portable device 6 (“match” in step ST4), a signal indicating the presence / absence of a delivery in the post 13 output from the post control unit 14 is transmitted to the portable device. 6 and recognized by the portable device 6 (step ST5). If there is a delivery item (YES in step ST5), the notification unit 23 of the portable device 6 notifies the user 5 of the delivery item. As the notification means 23, a buzzer or LED is used, and the user 5 is notified by a buzzer sound or LED lighting (step ST6). Thereby, the user 5 can recognize that there is a delivery in the post 13.
[0028]
Thereafter, the portable device 6 transmits the ID signal of the portable device 6 to the radio base station 8 (step ST7). The transmission / reception unit 16 of the radio base station 8 receives the transmitted ID signal (step ST8), and the ID collation unit 17 transmits the ID of the radio base station 8 and the transmitted ID signal (ID of the portable device 6). Is confirmed, an “open” signal of the gate 2 is output to the motor control unit 10 (step ST9). Upon receiving this signal, the motor control unit 10 drives the door driving motor 9 to rotate so as to open the gate 2.
[0029]
Further, the radio base station 8 transmits a lighting signal of the lamp 11 to the lamp control unit 12, and the lamp 11 is lit under the control of the lamp control unit 12 (step ST10). Thereby, since the gate 2 opens automatically and the electric light 11 lights up, the user 5 can pass through the front opening smoothly.
[0030]
Next, when the proximity detector 18 continues to detect the proximity of the portable device 6, the open state of the gate 2 is maintained (YES in step ST11). Thereafter, when the user 5 passes through the front opening of the gate 2 and the portable device 6 moves away from the gate side unit 4 (NO in step ST11), the proximity detector 18 detects a proximity to the portable device 6. In response to this, a “close” signal of the gate 2 is output to the motor control unit 10. Upon receiving this signal, the motor control unit 10 drives the door driving motor to rotate and operates to close the gate 2 (step ST12). And it returns to a standby state.
[0031]
Even if the portable device 6 can receive the signal output from the radio base station 8 (YES in step ST11), the ID of the portable device 6 and the ID of the gate side unit 4 cannot be verified. In this case (NO in step ST4), the gate 2 is closed and the initial state is returned (step ST12).
[0032]
In addition, when the door driving motor 9 is in an opening operation or a closing operation, the gate 2 comes into contact with an obstacle or the like and an overload is applied to the door driving motor 9. Will stop and ensure safety. Further, by operating an “open” button 10a, a “close” button 10b, and a “stop” button 10c provided in the motor control unit 10, the gate 2 can be opened and closed manually. That is, the gate 2 can be opened by pressing the “open” button 10a, the gate 2 can be closed by pressing the “close” button 10b, and the gate can be closed by pressing the “stop” button 10c. 2 can be stopped at that position. In addition, a non-contact sensor such as an infrared sensor is installed on the gate pillars 3a and 3b, and when the presence of an obstacle is detected by the infrared sensor, the opening and closing operation of the gate 2 is stopped, and the gate 2 and the obstacle It is also possible to avoid contact in advance. In addition, when the operation | movement of the gate 2 mentioned above is shown with a state transition diagram, it will become as shown in FIG.
[0033]
Thus, when the user 5 carries the portable device 6, the gate 2 can be automatically opened and closed.
[0034]
In this way, in the gate opening and closing system 1 according to the first embodiment, by performing bidirectional communication between the portable device 6 and the wireless base station 8, the ID of the portable device 6 and the gate side unit 4 have. The ID is collated, and when the ID collation is confirmed in both the portable device 6 and the wireless base station 8, the gate 2 is opened and closed.
[0035]
Therefore, the user 5 automatically opens the gate 2 just by carrying the portable device 6 and approaches the gate side unit 4, and automatically closes the gate 2 by moving away from the gate side unit 4. Therefore, troublesome operations such as manual opening / closing operations and pressing a switch of the portable device 6 can be omitted.
[0036]
Thereby, even when a person with luggage in both hands, an elderly person, or a wheelchair user passes, the opening / closing operation of the gate 2 can be easily performed. Further, since information such as the presence / absence of a delivery item can be recognized on the portable device 6 side, the user 5 can immediately know whether or not a delivery item has arrived. Moreover, since the electric lamp 11 can be turned on and off automatically, the periphery of the gate can be illuminated.
[0037]
Furthermore, since ID confirmation is performed by both the portable device 6 and the wireless base station 8, security when the gate 2 is opened and closed can be improved.
[0038]
Next, a second embodiment of the present invention will be described. FIG. 6 is a block diagram illustrating a configuration of a gate opening / closing system 31 according to the second embodiment. The overall configuration diagram is substantially the same as that of the gate opening / closing system 1 shown in FIG. 1, and the distance between the two gate pillars 3a and 3b (the width of the front opening) is configured so that the vehicle can pass through. Is different. Moreover, it differs in that the post 13 and the lamp 11 are not provided.
[0039]
As shown in FIG. 6, the gate opening / closing system 31 includes a gate side unit 32 installed on a garage gate, and a portable device 33 mounted in a vehicle 36 entering the garage. The gate side unit 32 includes a radio base station 8, a motor control unit 10, a door driving motor 9, an open button 10a, a close button 10b, a stop button 10c, and an antenna 15. In addition, since each component of the gate side unit 32 is the same as what was shown in FIG. 1, the same code | symbol is attached | subjected.
[0040]
The portable device 33 includes a transmission / reception means 34 that transmits and receives signals to and from the gate side unit 32, an ID collation unit 35 that collates an ID unique to the portable device 33 and an ID transmitted from the gate side unit 32. And a notification means 37 for notifying the driver of the vehicle 36 of various types of information transmitted from the gate side unit 32. And this portable machine 33 is comprised so that electric power may be supplied from the battery mounted in a vehicle and to operate | move.
[0041]
FIG. 7 is a flowchart showing the operation of the gate opening / closing system 31 according to the second embodiment of the present invention, and the operation of the second embodiment will be described with reference to the flowchart. As an initial state, the gate 2 is in a “ closed ” state, and the portable device 33 mounted on the vehicle 36 is in a reception standby state. Further, the gate side unit 32 transmits an ID signal unique to the gate side unit 32 through the antenna 15 (step ST21). The power on / off of the portable device 33 is synchronized with the on / off of the engine of the vehicle 36.
[0042]
Next, when the vehicle 36 on which the portable device 33 is mounted is close to the gate 2 (garage) (step ST22), a signal (ID signal) output from the wireless base station 8 is received by the portable device 33, and the portable device 33 is The received ID signal (the ID of the gate side unit 32) and the ID unique to the portable device 33 are collated (step ST24). When the collation is not performed ("mismatch" in step ST24), the standby state is again entered. Return. In this state, since the gate 2 is closed, the process of step ST29 is omitted.
[0043]
If the received ID matches the ID of the portable device 33 (“match” in step ST24), the portable device 33 transmits the ID signal of the portable device 33 to the radio base station 8 ( Step ST25). The transmitting / receiving unit 16 of the radio base station 8 receives the transmitted ID signal (step ST26), and the ID collating unit 17 transmits the ID of the radio base station 8 and the transmitted ID signal (ID of the portable device 33). Is obtained, the “open” signal of the gate 2 is output to the motor control unit 10 (step ST27).
[0044]
Upon receiving this signal, the motor control unit 10 drives the door driving motor 9 to rotate so as to open the gate 2.
[0045]
Next, when the proximity detector 18 continues to detect the proximity of the portable device 33, the gate 2 is kept open (YES in step ST28). Thereafter, when the vehicle 36 leaves the gate 2 (NO in step ST28), the proximity detection unit 18 cancels the signal for detecting the proximity to the portable device 33, and receives the signal to the motor control unit 10 to the gate 2 The “closed” signal is output. Upon receiving this signal, the motor control unit 10 drives the door driving motor 9 to rotate so as to close the gate 2 (step ST29). And it returns to an initial state.
[0046]
Even when the portable device 33 can receive the signal output from the radio base station 8 (YES in step ST28), the ID of the portable device 33 and the ID of the gate side unit 32 cannot be verified. In that case (NO in step ST24), the gate 2 is closed and the process returns to the initial state (step ST29). Further, when the engine of the vehicle is stopped, this signal is received and the gate 2 is closed to return to the initial state.
[0047]
Thus, by installing the portable device 33 on the vehicle 36, the gate 2 can be automatically opened and closed.
[0048]
In this way, in the gate opening / closing system 31 according to the second embodiment, by performing bidirectional communication between the portable device 33 and the wireless base station 8, the ID of the portable device 33 and the ID of the gate side unit 32 are provided. When the collation is confirmed by both the portable device 33 and the radio base station 8, the gate 2 is configured to be opened or closed.
[0049]
Therefore, the driver of the vehicle 36 automatically opens the gate 2 just by bringing the vehicle 36 carrying the portable device 33 close to the gate 2 and moves away from the gate side unit 32, so that the gate 2 is automatically opened. Since it can be closed, a manual opening / closing operation or a troublesome operation such as pressing a switch of the portable device 33 can be omitted. As a result, the operation when entering the vehicle can be greatly simplified.
[0050]
