Abstract

PROBLEM TO BE SOLVED: To provide an electric shutter operable from a radio transmitter installed outside. SOLUTION: A radio transmitter is provided with a code input key in addition to an operation key. Any operation key for ID code, ascent, stop, and descent is pressed at S41 to operate an electric shutter. When ID code coincides with the ID code registered in the radio transmitter, the operation is shifted from S42 to S43 to transmit a transmission signal, but when it does not coincide with the latter, transmission is not done. Moreover, it is unnecessary to input the ID code to stop the shutter. The ID code is read from a memory at S45 and a transmission signal is sent at S46. It is unnecessary to input the ID code to lower the shutter in the same way.

1 and 2 are views for explaining an example of an embodiment of an electric shutter according to the present invention. FIG. 1 is a block diagram, and FIG. FIG. In the figure, 1 is a shutter slat, 2 is a switchgear, 3 is a switchgear control panel, 4 is a receiver, 5 is an obstacle detector, 6 is an obstacle detection signal transmitter, 7 is an obstacle detection signal detector, 8 is an antenna, 9 is a portable wireless transmitter, 10 is a wireless transmitter for indoor installation, 11 is a wireless transmitter for outdoor installation, 1
2 is a push button switch input terminal, and 13 is a case. In FIG. 2, the left side of the shutter slat 1 is the indoor side, and the right side is the outdoor side.

The shutter slat 1 is installed at an opening of a building or the like and is moved up and down by a switch 2 having a drive motor. The switchgear 2 is controlled by a switchgear control panel 3.
Given to.

When the descending shutter slat 1 comes into contact with an obstacle, that is, when there is an obstacle such as luggage or a person between the seat plate of the shutter slat 1 and the floor,
An obstacle sensing unit 5 provided on a seat plate or the like senses a force received by contact with an obstacle, and transmits an obstacle sensing signal from an obstacle sensing signal sending unit 6 to an obstacle sensing signal sensing unit 7;
The detection signal from the obstacle detection signal detection unit 7 is input to the reception unit 4. In this embodiment, similarly to the conventional example, the obstacle detection unit 5 operates the seat plate switch by the seat plate that is moved by being pushed by the obstacle, and the obstacle detection signal transmission unit 6 transmits the digital infrared signal. And an obstacle detection signal detection unit 7 having a light receiver converts an infrared signal into an electric signal and sends a detection signal to the reception unit 4.

The portable wireless transmitter 9 can be carried, for example, loaded on a vehicle. A plurality of portable wireless transmitters 9 can be used as needed by the user. The indoor-installed wireless transmitter 10 has the same specifications as the portable wireless transmitter 9, but is mounted on an indoor wall or the like. The outdoor-installation wireless transmitter 11 is installed outdoors, such as an outer wall of a building. When using the wireless transmitter for operation from the indoor side and operation from the outdoor side,
Since there is no need to perform wiring, there is an advantage that wiring work and piping work are unnecessary.

The push button switch input terminal 12 is used to connect the push button switch to the main building when the shutter is installed in a garage for an automobile remote from the main building, thereby transmitting radio waves from the radio transmitter. It is possible to operate the shutter from the main house where infrared rays do not reach. It is also possible to connect the indoor push button switch described in FIG.

In this embodiment, the radio transmitter uses a radio wave as a carrier wave to transmit a digital signal, but may transmit an infrared ray as a carrier wave. A carrier wave such as an ultrasonic wave may be used.

The operation of raising and lowering the shutter will be described.
The portable wireless transmitter 9, the indoor-installed wireless transmitter 10, and the outdoor-installed wireless transmitter 11 include an ascending key, a descending key, and a stop key for instructing respective operations of "up,""down," and "stop." It has two operation keys and can operate the shutter. However, the wireless transmitter for outdoor installation 1
Numeral 1 is provided with a numeric keypad in addition to the above three operation keys, and unless the registered ID number is input,
Even if an operation key is operated, the shutter cannot be controlled.

The ID numbers of the portable wireless transmitter 9 and the indoor-installed wireless transmitter 10 are registered in the receiving unit 4, and the wireless numbers other than the registered portable wireless transmitter 9 and the indoor-installed wireless transmitter 10 are registered. The shutter is not activated by the operation signal from the transmitter. However, in the portable wireless transmitter 9 and the indoor-installed wireless transmitter 10, when operating the operation key, the code signal of the ID number stored in each transmitter is automatically added together with the operation signal. Sent. Therefore,
As for the ID number, if the ID number of each wireless transmitter is registered in the receiving unit 4 first, the user can operate the shutter with the wireless transmitter.

The push-button switch connected to the push-button switch input terminal 12 also has three operation keys, an up key, a down key, and a stop key. By
Operation from a place where radio waves and the like from the portable wireless transmitter 9 do not reach is enabled, but if it is not necessary, there is no need to wire the push button switch input terminal 12.

The operation of the shutter when the contact of an obstacle is sensed while the shutter slat 1 is descending is stopped immediately when the obstacle is sensed, rises for a predetermined time, and stops there or rises. Operation to make it descend again after a predetermined time has elapsed from the time when it stopped, or if obstacles are not removed during this time,
An operation of sensing the obstacle again during the descending again, stopping, ascending, and repeating this operation, or an operation of preventing further descending after the second ascent, etc. Is designed to perform the above operation. A program for performing a plurality of operations described above may be incorporated, and the program may be selected by a dip switch or the like.

When a seat plate switch is used as the obstacle sensing unit 5, it is recognized that an obstacle has been detected when the shutter slat descends and the seat plate touches the floor or the like in a normal closing operation. However, there is a risk of a malfunction such as re-elevation after stopping. In this embodiment, the lower limit switch for detecting the lower limit of the lowering of the shutter slat is detected at a position 10 to 20 mm before the ground contact position (a value of 10 to 20 mm is an example, and is not limited to this. It is not something that can be done.) When the seat plate switch is operated in a state where the lower limit switch is operated, it is determined that the seat plate switch is in contact with the floor surface or the like, and the operation is stopped. The predetermined time for performing the reversal rise is adjustable in a range of, for example, 0 to 1.5 seconds. When the predetermined time is set to 0, the operation is stopped by the operation of the seat plate switch. When this predetermined time is set to a value other than 0, the reversal rises to such an extent that no gap is opened with the floor surface or the like.

The obstacle sensing signal sending section is turned on by the operation of the seat plate switch and sends an obstacle sensing signal. The power supply circuit is controlled by a timer circuit so as to be cut off after a certain period of time. . The timer circuit may be an analog circuit or a digital circuit. Therefore, even if the seat panel switch continues to operate in the closed state, the power is not unnecessarily consumed.

When the seat plate switch is operated before the lower limit switch is operated (generally, when an obstacle is detected), the seat plate switch reversely rises for 5 seconds and stops. Although it may be made to descend again after a predetermined time, in this specific example, the stop state after the reversal ascent is maintained. By performing the lowering operation after removing the obstacle, the closing operation of the shutter can be completed.

In this embodiment, the radio transmitter 21
Although the same one used as a portable wireless transmitter is used, it may have a function of disabling the shutter when it is removed from the mounting base in consideration of theft or the like. The wireless transmitter 21 is provided with an up key 22, a stop key 23, and a down key 24. By pressing these keys, an operation signal including an ID number can be transmitted. The battery exhaustion display section 25 performs lighting display when the voltage of the built-in battery becomes equal to or lower than a predetermined voltage. However, it is preferable in terms of energy efficiency that the display be made intermittently. The code registration / deletion switch 26 is
Is provided for performing registration and deletion operations of the ID code of another wireless transmitter registered in the small hole. An on / off switch is installed at the back of the small hole, and a thin needle-shaped object is inserted. In this way, a switch operation is possible.

The mounting base 27 is provided with a mounting screw 29 and a mounting hole 28.
And attached to a wall, pillar, etc. After attaching the mounting base 27, the wireless transmitter 21 is mounted, and the decorative cover 31 is fitted into the mounting base 27. The upper and lower inner walls of the decorative cover 31 have engaged portions that engage with the engaging pieces 30 of the mounting base 27. When the decorative cover 31 is fitted, the engaged portions of the decorative cover 31 are engaged with the engaging pieces 30. Engage with and dig into. The engagement piece 30 has elasticity.

As described above, the decorative cover 31 is attached so that it cannot be removed without using an appropriate tool. Therefore, the wireless transmitter 21 fixed to the wall surface by hand alone without using a tool is removed. Can not do. Such a fixed state of the wireless transmitter that cannot be removed by hand alone is referred to as a substantially irremovably fixed state in this specification.

Since the wireless transmitter 21 is fixed so as to be substantially non-removable, the wireless transmitter 21 mounted on the indoor wall can be prevented from being stolen from anyone who does not know how to remove it.

FIG. 5 is a perspective view of a wireless transmitter for outdoor installation. In the figure, 40 is a wireless transmitter main body for outdoor installation, 41
Is a mounting hole, 42 is an up key, 43 is a stop key, 44 is a down key, 45 is a code input key, 46 is a cover, 47 is a code registration / deletion switch, 48 is an anti-theft switch,
49 is a battery cover, and 50 is a decorative cover.

The wireless transmitter main body 40 for outdoor installation is fixed by screwing a mounting screw (not shown) into the mounting hole 41 to an outer wall or the like. After the screws are fixed, the mounting portion is covered with the decorative cover 50. Therefore, unless the decorative cover 50 is removed, it cannot be removed from the outer wall or the like to which the wireless transmitter main unit 40 for outdoor installation is attached. As will be described later, the decorative cover 50 is fitted and attached to the outdoor-installed wireless transmitter main body 40 in this embodiment.
FIG. 4 shows a state in which the engaging pawl is engaged with the engaging pawl, and the engaging pawl is removed by a tool.
Alternatively, an attachment structure that cannot be easily removed by hand, such as the structure described in the above, may be employed. It is preferable to provide an elastic packing or the like on the joint surface of the decorative cover 50 with the outdoor-installed wireless transmitter main body 40 to provide a waterproof structure.

Operation keys such as an up key 42, a stop key 43, and a down key 44, and nine code input keys 45 are provided on a surface above the surface covered by the decorative cover 50.
The nine code input keys 45 correspond to the numerals 1 to 9, but may be provided with ten code input keys by adding 0, or with eight or less code input keys, Only some numbers may be used. These keys are covered by a cover 46. The cover 46 is
It is attached by a rotating shaft, and when a key is operated, it is opened upward as shown in the figure to expose the key operation surface. It is preferable that the cover 46 be made waterproof so that rainwater does not enter the key operation surface when the cover 46 is closed. It is also good to adopt a waterproof structure for the key operation surface.

FIG. 4 shows a portion covered with the decorative cover 50.
A code registration / deletion switch 47 similar to that described in
An anti-theft switch 48 is provided. The anti-theft switch 48 also has a structure using an on / off switch installed at the back of the small hole, and has the same structure as the code registration / deletion switch 47. The anti-theft switch 48 is connected to the makeup cover 5
0, a protruding member protrudes from the back side of the decorative cover 50.
Is pressed, the anti-theft switch 48 is pressed to turn off the switch. When the decorative cover 50 is removed, the anti-theft switch 48 is turned on, and a control unit having the CPU of the wireless transmitter generates a theft signal.

FIG. 6 is an explanatory diagram of the battery replacement of the wireless transmitter for outdoor installation. In the figure, the same parts as those in FIG. 51 is a coin, 52 is a battery storage unit, and 53 is a button battery.

To replace the battery, the coin cover 51 is used to open the decorative cover 50 as shown in FIG.
Wireless transmitter body 4 for outdoor installation below the decorative cover 50
There is a slit-shaped notch (not shown) at the boundary with zero, and the cosmetic cover 50 can be removed by inserting and coining the coin 51 into this notch. As described above, since the mounting structure of the decorative cover 50 is not limited to the structure for removing with a coin, the decorative cover 50 is removed by applying a tool or a removing method suitable for the mounting structure.

Although the battery cover 49 is removed, the battery cover 49 can also be removed with a coin. As shown in FIG. 6B, the coin cover 49 is removed, the battery is taken out, a new button battery 53 is inserted into the battery housing 52, the battery cover 49 is attached, and the decorative cover 50 is attached. The battery is not limited to a button battery, and another type of battery may be used.

FIG. 7 is an example of a flowchart showing the operation of the anti-theft switch. In the wireless transmitter, the power switch is not turned on in the standby state. When the three types of operation keys, the up key, the stop key, and the down key, and the code input key are pressed, the key switch corresponding to each key is turned on, the power is turned on, and the signal corresponding to the key is generated. Stored in memory. The supplied power is turned off after a lapse of a predetermined time, for example, 5 seconds. Therefore, if the next key is pressed within this predetermined time,
Although continuous input is possible, during a series of key operations, if the key operation is interrupted and a predetermined time elapses, the power is turned off and the key input becomes invalid.

Further, since the radio transmitter is installed outdoors, there is a security problem if the shutter is operated simply by pressing the operation key. Therefore,
With the operation of the operation key, the ID determined by the wireless transmitter
Code is input with the code input key. In one example, the operation key is pressed after the ID code is input, but this order may be reversed. As the ID code, a specific code is determined at the time of shipment by the wireless transmitter, but the user can change the ID code to a desired code. The changed ID code is stored in the wireless transmitter and transmitted, and the registration data of the receiving unit is updated.

FIG. 7A shows a flow of inputting a normal shutter operation. Code input key and up,
When the operation keys for performing the operations of stop and descent are pressed at intervals that do not elapse the predetermined time, and the respective key switches are sequentially turned on, the flow starts. S1
In step 1, the input ID code is compared with the ID code registered in the wireless transmitter, and if the input ID code does not match the registered ID code, an operation signal is transmitted. Power off and end the flow. If the input ID code matches the ID code registered in the wireless transmitter in S11, the process proceeds to S12, where the operation signal and the ID code corresponding to the operation key are transmitted, and the power is turned off. End the flow. Even when the input ID code does not match the registered ID code, the operation signal and the inappropriate ID code may be transmitted. Since the ID code is checked in the receiving unit, the shutter does not operate. It is more advantageous not to transmit when the ID codes do not match from the viewpoint of battery life.

As described above, the power may be forcibly turned off by the control unit, but the power may be turned off after the elapse of the predetermined time to end the flow. Good.

FIG. 7B is a flow chart when the anti-theft switch is activated. When the anti-theft switch is activated, the flow starts. At S13, a theft signal is created. The theft signal may be a specific code signal, a signal indicating that the anti-theft switch has been activated, or a signal corresponding to an activation signal for setting the potential of a specific portion to the H level or the L level. . Then S1
Proceed to 4 to transmit a theft signal indicating that the anti-theft switch has been activated, together with the ID code. In this case, the control unit of the wireless transmitter reads the ID code from the memory and transmits the ID code to the receiving unit together with the theft signal. This ID code does not need to be added, but if there is another shutter system in an area where the transmission signal of the wireless transmitter can be received, a malfunction may occur. In order to prevent this malfunction,
It is desirable to add a D code and transmit. S15
Then, a buzzer provided in the wireless transmitter is sounded.
In this case, it is preferable to perform an operation for continuing to turn on the power. Therefore, the loop of S15 continues, and the buzzer continues to sound. This ringing continues until the battery is exhausted. In this way, the stolen person is likely to have a pain in holding it and throw it away on the spot, thus preventing theft. When the anti-theft switch is activated, a circuit for performing self-holding may be provided, or a theft signal may be stored so that the buzzer cannot be stopped even if the anti-theft switch is pressed.

FIG. 8 is an example of a flowchart showing the operation of the receiving section that has received the stolen signal. When no signal has been received, S21 and S22 are looped to be in a standby state. When the operation signal is received, the process proceeds from S21 to S22, where the ID code is checked for coincidence. If the ID code matches the registered ID code, the ascending operation, the stopping operation, or the descending operation is performed according to the operation signal. Do. If the ID codes do not match, the process returns to the standby state loop without operating the shutter, but illustration thereof is omitted.
If a stop signal is received during the ascending operation or the descending operation, the stopping operation is performed. When the stolen signal is received, the process proceeds from S22 to S24, where the received ID code is checked. If the ID code matches the registered ID code, the buzzer of the receiving unit is sounded. The ID code registered for the device is deleted from the receiving unit. Next, the operation of the receiving unit is stopped (for example, the power is turned off), and the flow is terminated. Then, it can be seen that the outdoor wireless transmitter has been stolen because the shutter does not operate even if the other wireless transmitter or the push button switch as described in FIG. 11 is operated. Also, without ending the flow, as shown by the broken line,
The process may return to the loop in the standby state. In any case, it is preferable that the buzzer sound in S24 does not last for a long time. If the ID code added to the theft signal does not match in S25, the process returns to the standby loop without operating the shutter, but illustration thereof is omitted.

The deletion of the registered ID code in S25 may not be performed.

As described above, if the buzzer of the wireless transmitter or the receiving unit is caused to sound when the anti-theft switch is operated, there is a problem that the buzzer sounds when the battery is replaced. The power of the buzzer on the receiving unit side may be turned off. Also, since the buzzer of the wireless transmitter sounds until the battery is removed,
It sounds short and you can't stand it. However, it is not always preferable that the buzzer sounds even in a short time when the battery is replaced. In addition, turning off the power of the receiving unit when replacing the battery is complicated, and the power-off operation may be forgotten. Then, it is preferable that the buzzer is not sounded when the battery is replaced.

FIG. 9 is an example of a flowchart showing the operation when the anti-theft switch is operated based on the above request. In this embodiment, the user inputs the ID code of the wireless transmitter and then removes the cosmetic cover before removing the cosmetic cover for battery replacement or the like. ID
After inputting the code, the makeup cover may be removed by performing a predetermined key operation, for example, a key operation such as pressing a stop key three times. In any case, if a specific key operation for inputting an ID code is performed before removing the makeup cover, until a certain time elapses,
Prevent theft signal from being created.

In the wireless transmitter, the above-mentioned ID code is input, and the code is stored in the ID stored in the wireless transmitter.
If the codes match, a timer for a predetermined time, for example, 5 minutes is started and the timer is turned on. The timer may be a counting digital timer or an analog timer. When the anti-theft switch is activated, in S31,
It is checked whether the timer is on. I
If the D code has not been input, or if 5 minutes have elapsed even after the ID code has been input, the process proceeds to S33 to S35 because the timer is not on. S33
Steps S35 to S35 are the same as steps S13 to S15 described with reference to FIG. If the timer is on when the anti-theft switch is activated, S32, S36
Loop. During this time, no theft signal is generated. Therefore, even if the makeup cover is removed, the buzzer of the wireless transmitter or the receiving section does not ring or the theft signal is not transmitted. If work such as battery replacement is completed during the loop of S32 and S36 and the decorative cover is attached,
Then, since the anti-theft switch is turned off, the power of the wireless transmitter is turned off and the flow ends. If five minutes have elapsed without the anti-theft switch being turned off, the process goes from S32 to S3.
The process shifts from S3 to S35 to enter the theft mode.

As described above, if the user does not shift to the theft mode even if the makeup cover is removed within a predetermined time on condition that the ID code is input, the user can remove the makeup cover for battery replacement or the like. However, the buzzer does not sound.

In the above-described embodiment, a theft signal is not generated until a predetermined time elapses after the ID code is input. However, a theft signal may be generated. The operation based on the theft signal, such as not sounding the buzzer or transmitting the theft signal, may be performed.

When the timer is reset when the battery is replaced, the anti-theft switch is turned on when the battery is replaced, so that the mode may be shifted to the theft mode. In order to prevent this, at the time of starting up the power supply by replacing the battery, it is only necessary to prevent the transition to the theft mode until a predetermined time has elapsed since the battery was inserted.

FIG. 10 is a flowchart for explaining another example of the embodiment of the transmitting operation of the outdoor-use wireless transmitter. S41 to S43 are the same as the flow described in FIG. That is, if the ID code and any of the operation keys of the up key, the stop key, and the down key are operated in S41, the input ID code is checked in S42, and if the ID code is correct, the process proceeds to S43. Then, the ID code data and the operation code data corresponding to the pressed operation key are transmitted, and the flow ends. If the input ID code is incorrect, the flow is terminated without transmitting, but the transmission may be performed.
This is as described with reference to FIG.

In this embodiment, it is not necessary to input an ID code for stopping and descending. S4
This is the flow from S4 to S46 and S47 to S19. S
When the stop key is pressed in 44, the ID code data of the wireless transmitter stored in the memory is read out in S45, and the stop signal data is transmitted with the ID code data added in S46. If the down key is pressed without inputting the ID code, the process proceeds from S47 to S48,
Similarly, in S48, the ID code data is read, and
At 49, ID code data is added and descending signal data is transmitted.

In this embodiment, as described above, the stop operation and the descending operation can be transmitted without inputting the ID code from the code input key. The ON / OFF of the power supply is the same as that described with reference to FIG.

In this embodiment, it is not necessary to input the ID code for the stop operation and the descending operation. However, the ID code may not be input only for the stop operation. In addition, an ID code may be input for a stop operation or a descending operation that does not require the input of an ID code. However, for a stop operation or a stop operation and a descending operation, only a key operation without inputting an ID code is performed. It may be. Alternatively, whether or not the operation can be performed without inputting the ID code may be selected by a dip switch or the like.
