Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control receiving apparatus provided with storage means for collating a pattern included in a radio signal from a transmitting apparatus. [0002] Generally, a wireless remote control receiving apparatus as this type of remote control receiving apparatus stores a pattern contained therein when a wireless signal is transmitted from the wireless remote controlling transmitting apparatus. The pattern is compared with the pattern stored in the pattern storage means, and only when the two patterns match, the operation signal from the remote control transmission device is accepted to control the load, for example, a shutter, which is dependent on the wireless remote control reception device. I am trying to do it. However, if the wireless remote control transmitting device paired with the wireless remote control receiving device is accidentally lost, a person other than the owner may use the lost wireless remote control transmitting device to move the load without permission. In order to avoid use (abuse), it is necessary to erase the pattern stored in the pattern storage means. Conventionally, such a pattern erasing method in the pattern storage means has been performed by an electrical method by connecting a dedicated cable between the wireless remote control receiving device and a dedicated erasing device. In the above-mentioned dedicated cable, since the erasing device is separate from the wireless remote control receiving device, it has to be connected from the exterior of the wireless remote control receiving device to the pattern storage means inside the external device. Special processing such as making a hole in the exterior is necessary so that the probe at the tip, for example, can be mounted inside the exterior. In addition, the holes are closed by members such as a character sheet and a cover panel so as not to impair the appearance in normal times. However, when connecting the dedicated cable, it is necessary to disassemble the character sheet and the cover panel each time, and a service person must be called to perform such disassembly. Further, it takes time for a serviceman to visit a general user, and during that time, there is a possibility that a person other than the owner abuse the lost wireless remote control transmitter. In addition, it is necessary to separately purchase an erasing device and a dedicated cable, which are dedicated tools, resulting in an extra cost. The present invention has been made to solve the above-mentioned problem. Even if a dedicated tool is used or a hole through which a dedicated cable is passed is formed in an exterior, and the hole is not closed by a member, the memory can be stored. It is an object of the present invention to provide a remote control receiver capable of easily and quickly deleting a set pattern. [0006] A remote control receiver according to the present invention comprises an operation means, a storage means, and a control means for performing control by comparing a pattern included in a signal with a stored pattern. And a pattern erasing means for erasing the pattern when the above operation is performed. In this case, when a signal is received from the transmitting device, the control means checks the pattern included in the signal with the stored pattern. However, in a normal use state, both patterns match. Thus, the dependent load can be controlled. However, if a specific operation is performed on the remote control receiving device, the stored pattern is erased, and thereafter, even if a signal from the transmitting device is received, both patterns do not match. The load can no longer be controlled. As described above, only by performing a specific operation,
Misuse of the transmitter by anyone other than the owner can be easily avoided, eliminating the need for conventional dedicated tools,
There is no need to open a hole for passing a dedicated cable through the exterior or to close the hole with a member. Furthermore, since the operation can be performed by a general user, it is not necessary to call a service person, and the treatment can be performed in a short time. An embodiment of a remote control receiving apparatus according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a wireless remote control transmitting device 11 as a transmitting device in addition to a wireless remote controlling receiving device 1 as a remote control receiving device.
It is a figure showing the appearance of. Wireless remote control receiver 1
Although not shown here, for example, the main body 2 is attached and fixed to a wall near the window, and controls the opening / closing operation of an opening / closing body 31 (see FIG. 2) such as a shutter attached to the window. Is what you do. In the wireless remote control receiving apparatus 1, as a switch operating means 3 which is an operating means that can be directly operated by the user U from the outside, an open switch 4 operated when opening the opening / closing body 31 and an operation of the opening / closing body 31 are stopped. Stop switch 5 to be operated at the time, a closing switch 6 to be operated to close the opening / closing body 31, and a change / setting switch 7 to be operated at the time of switching or setting various modes for operating the opening / closing body 31. It has. In addition, the wireless remote control receiver 1 further includes a wireless receiving unit 8 for receiving a wireless signal from the outside, a light emitting display unit 9 such as an LED that lights when the opening / closing body 31 is in an open or closed state, and For example, an LCD display means 10 such as a liquid crystal display for displaying a timer time and various setting states is provided. On the other hand, a portable wireless remote control transmitting device 11
Is used to control the opening / closing operation of the opening / closing body 31 from a remote place using a wireless signal.Specifically, the transmitting means 12 for transmitting a wireless signal to the outside and the opening / closing body 31 are opened. , An open switch 13 operated to stop the operation of the open / close body 31, a close switch 15 operated to close the open / close body 31, and a half open operated to open the open / close body 31 halfway. A switch 16 is provided. Note that the wireless remote control receiving means 1 is not provided with an independent half-open switch, but by holding down the close switch 6 for a predetermined time (for example, 3 seconds) or more, the same function as the half-open switch 16 of the wireless remote control transmitter 11 is obtained. The function is performed so that the number of switches of the wireless remote control receiving means 1 installed on the wall is not unnecessarily increased. Next, the internal configuration of the wireless remote control receiver 1 will be described with reference to FIG. In the figure, 21 incorporates a device control program such as an opening / closing body 31,
This is a microcomputer including a control unit 22 that executes processing according to the device control program. The microcomputer 21 includes a switch input unit 23 for receiving an operation signal from the switch operation unit 3, a display control unit 24 for controlling display on the light emitting display unit 9 and the LCD display unit 10, and reception by the wireless reception unit 8. And a wireless signal input means 25 for receiving the transmitted wireless signal and sending it to the control means 22. Reference numeral 26 denotes pattern storage means as storage means for storing an individual pattern included in a wireless signal from the wireless remote control transmission device 11, and the microcomputer 21, for example, keeps pressing a specific switch for 10 seconds, When a special operation of the switch operating means 3 is performed, a pattern erasing means 27 for erasing an individual pattern stored in the pattern storing means 26, and when the wireless receiving means 8 receives a wireless signal, A pattern checking unit 28 is provided for checking the included pattern against the individual pattern stored in the pattern storage unit 26 for checking. Further, a load 32 such as a motor is provided here as a driving means for opening and closing the opening / closing body 31, and an external switching output means 30 is provided from the control means 22 through an external switching means 29 provided in the microcomputer 21. The operation of the load 32 is switched when a switching signal is output to the switch 32. In the present embodiment, the wireless remote control transmitting device 11 transmits a weak
Although the configuration is such that the load 32 depending on the remote control can be remotely controlled, for example, infrared rays may be used instead of wireless. However, since infrared rays may be cut off when a person approaches, when a load is not so far away, it is preferable to use wireless communication for reliable remote control. Next, an operation procedure in the above configuration will be described with reference to FIG. First, the operation procedure when the wireless remote control transmitting device 11 is operated will be described. An open switch provided on the wireless remote control transmitting device 11 with the opening / closing body 31 closed is described.
When 13 is pressed, a control command for opening and closing the opening / closing body 31 is provided,
A wireless signal including a pattern unique to the wireless remote control transmitter 11 is transmitted from the transmitter 12. When this is received by the wireless receiving means 8 of the wireless remote control transmitting apparatus 1 and taken into the control means 22 through the silent signal input means 25, the pattern confirmation means
Reference numeral 28 compares and matches the individual pattern stored in the pattern storage means 26 with the pattern included in the wireless signal. If the two patterns match, and the pair of the wireless remote control receiver 1 and the wireless remote controller transmitter 11 can be confirmed by the pattern confirmation unit 28, the control unit 22 opens and closes by the load 32 based on the control command. A switching signal for opening the body 31 is sent from the external switching means 29 to the external switching output means 30. As a result, with the operation of the open switch 13, the load 32 rotates forward and the opening / closing body 31 opens. On the other hand, if the two patterns do not match, and the pair cannot be confirmed by the pattern confirmation unit 28, the control unit 22 does not output a switching signal to the external switching unit 29. Therefore, in this case, even if the open switch 13 is operated, the opening / closing body 31 does not operate. Similarly, when the stop switch 14, the close switch 15 or the half-open switch 16 of the wireless remote control transmitting device 11 is operated, the wireless remote control receiving device 1 stores the individual patterns included in the wireless signal and the pattern storing means 26. The open / close body 31 is closed, stopped, or half-opened in correspondence with each of the switches 14 to 16 only when a pair is confirmed by comparing the individual pattern with the individual pattern that has been performed. The switching signal to be output from the external switching means 29 to the external switching output means 30. That is, when the two patterns do not match, no matter how the wireless remote control transmission device 11 is operated, the opening / closing body 31 does not operate at all. Next, the operation related to the switch operating means 3 of the wireless remote control receiver 1 will be described. As shown in the flowchart of FIG. 3, when the switch operating means 3 is turned on by pushing the switch operating means 3 in step S1, the control means 22 which receives this switch operating signal from the switch input means 23
In the next step S2, the time during which the switch operating means 3 is kept pressed (on time) is counted, and it is determined in step S3 whether or not 10 seconds have elapsed. In this step S3, if the specific switch operating means 3 is kept pressed for 10 seconds, the pattern erasing means 27
, The individual pattern stored in the pattern storage means 26 is completely erased (step S4), but if the time during which the switch operation means 3 is pressed is within 10 seconds, a normal switching signal corresponding to the switch is output to the external switching means. It is output from 29 to the external switching output means 30. Normally, the opening / closing body 31 is opened (including half open), the opening / closing body 31 is closed, or the opening / closing body 31 in operation is operated.
When the user U operates the switch operating means 3 to stop the operation, the user does not press the specific switch operating means 3 for more than 10 seconds, so that a switching signal corresponding to the switch operation is given to the load 32, The normal operation of the opening / closing body 31 is controlled via the control means 22. On the other hand, if the wireless remote control transmitting device 11 is lost, the user U performs an operation that cannot normally operate the switch operating means 3, for example, an operation that keeps pressing a specific switch (for example, the open switch 4 and the close switch 6) for 10 seconds. Do. Then, in the microcomputer 21, the pattern erasing means 27 erases the individual pattern stored in the pattern storing means 26. After this operation, even if a wireless signal from the lost wireless remote control transmitter 11 is received, when the pattern is checked by the pattern checking means 28, the two patterns do not match, and the pair cannot be checked. That is, no matter how the person other than the user U operates the wireless remote control transmitter 11, no switching signal is output to the external switching means 29, and the opening / closing body 31 cannot be operated without permission. For example, if a specific switch is erroneously set to 10
When pressed for more than a second and the individual pattern stored in the pattern storage means 26 is erased, a special operation is performed by the switches 13 to 16 of the wireless remote control transmitter 11 (for example, the open switch 13 and the close switch 15 at the same time 10
By pressing the button for more than one second), a wireless control signal for storing the same pattern as that of the wireless remote control transmitting device 11 in the pattern storing means 26 is transmitted. At this time, it is preferable that the wireless remote control receiver 1 is configured not to permit writing of a new individual pattern by the wireless control signal unless some special operation is performed. Thus, only by performing a special operation from the wireless remote control transmission device 11 by a person other than the user U, an individual pattern matching the wireless remote control transmission device 11 is easily written into the pattern storage means 26, and the opening / closing member 31 is controlled. Can be prevented. As described above, in this embodiment, the switch operation means 3, the pattern storage means 26, the pattern included in the received signal and the pattern stored in the pattern storage means 26 are collated, and the two patterns match. A control means 22 for controlling the load when the operation is performed, and a pattern erasing means 27 for erasing the pattern stored in the pattern storing means 26 when a specific operation is performed on the switch operating means 3. In this case, upon receiving a signal from the wireless remote control transmitting device 11 which is a transmitting device, the control means 22 of the wireless remote control receiving device 1 transmits a pattern included in the signal and an individual stored in the pattern storing means 26 in advance. The pattern is compared with the pattern. In a normal use state, the two patterns match, so that the dependent load 32 can be controlled using the wireless remote control transmitter 11. However, when a specific operation is performed on the switch operating means 3 provided in the wireless remote control receiving apparatus 1, the pattern stored in the pattern storing means 26 is deleted, and thereafter, the signal from the wireless remote control transmitting apparatus 11 is received. Will not match both patterns,
The load 32 cannot be controlled using the wireless remote control transmitter 11. As described above, the erroneous use of the wireless remote control transmitting device 11 by a person other than the owner can be easily avoided only by performing a specific operation on the switch operating means 3. This eliminates the necessity of opening a hole for passing a dedicated cable through the exterior and closing the hole with a member. Furthermore, since the operation can be performed by a general user, it is not necessary to call a service person, and the treatment can be performed in a short time. The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. For example, the load in the above embodiment is not limited to a motor, and a plurality of subordinate loads 32 may be provided. Further, after the pattern stored in the pattern storage unit 26 is deleted by the pattern storage unit 27, a random pattern different from this pattern may be stored in the pattern storage unit 26. In this way, even if the pattern in the wireless remote control transmitting device 11 is rewritten, it is extremely difficult to match the pattern with the pattern stored in the pattern storage means 26 of the wireless remote control receiving device 1, and Abuse can be reliably prevented. According to the remote control receiving apparatus of the present invention, erroneous use of the transmitting apparatus by a person other than the owner can be easily avoided only by performing a specific operation. The stored pattern can be easily and quickly erased without using a cable or opening a hole for passing a dedicated cable through the exterior and closing the hole with a member.
