Description

  The present invention relates to a receiving apparatus used mainly for remote operations such as locking / unlocking a gate and opening / closing a shutter.

  In recent years, in addition to directly operating the locking and unlocking of the gate and opening and closing of the shutter with a mechanical key, it is common to transmit an operation signal from a portable transmission device to a reception device and remotely operate from a remote location There is a need for an inexpensive and reliable operation.

  Such a conventional receiving apparatus and communication system will be described with reference to FIGS.

  FIG. 3 is a block circuit diagram of a conventional communication system. In FIG. 3, reference numeral 1 is a receiving means such as an antenna, 2 is a control means such as a microcomputer, and a wiring board having a plurality of wiring patterns formed on the upper and lower surfaces (FIG. These are mounted, and the receiving means 1 is connected to the control means 2 to constitute the receiving device 3.

  Reference numeral 4 denotes a portable transmission device, in which a transmission unit 5 such as an antenna, a control unit 6 such as a microcomputer, and switches 7A and 7B are mounted on a wiring board (not shown), and are identified differently for each transmission device. The transmission means 5 and the switches 7A and 7B are connected to the control means 6 in which codes and operation codes are stored.

  Further, these are covered with a substantially box-shaped case made of an insulating resin (not shown), and a push button or the like protruding from the case is attached to the switches 7A and 7B to form the transmission device 4.

  In the case of the receiving device 3 and the transmitting device 4 that perform remote operation using such radio waves, a pair of the receiving device 3 and the transmitting device 4 are used before use in order to prevent erroneous operation by other transmitting devices and receiving devices. In general, a setting that enables operation only as a pair, so-called pairing, is performed.

  That is, in the above configuration, first, after the receiving device 3 is set to the pairing setting state by a predetermined operation, for example, when the push button for unlocking of the transmitting device 4 to be paired is pressed, for example, the electrical of the switch 7A As shown in the signal code diagram of FIG. 4 (a), an identification code L1 that is different for each transmission device and an operation code M1 for unlocking the gate are detected. The operation signal formed from is transmitted from the transmission means 5 as a radio wave.

  Then, the receiving means 1 of the receiving device 3 receives this operation signal, and the control means 2 stores the unique identification code L1 for each transmitting device, whereby the receiving device 3 and the transmitting device 4 are operated as a pair. The possible pairing settings are complete.

  The paired receiving device 3 is mounted at a predetermined location such as a gate or a shutter, and the control means 2 of the receiving device 3 is connected to a battery or an AC power source by a connector or a lead wire (not shown). (Not shown) and a gate lock mechanism (not shown) and a driving means 8 such as a motor for driving opening and closing of the shutter are electrically connected to constitute a communication system.

  In the above configuration, when the switch 7A for unlocking the gate, for example, of the portable transmission device 4 is pressed from a certain distance from the gate, the identification code L1 and the gate unlocking as shown in FIG. An operation signal formed from the operation code M1 is transmitted from the transmission device 4 as a radio wave.

  When the receiving means 1 of the receiving device 3 receives this operation signal, the control means 2 determines the identification code L1 in this operation signal, and when it is the same as that of the transmitting device 4 stored at the time of pairing In accordance with the operation code M1, a drive signal is output from the control means 2, and the drive means 8 is driven to unlock the gate.

  In other words, in addition to directly opening and closing the gate and opening and closing the shutter with a mechanical key when approaching the gate and shutter, the gate can be locked and unlocked even from a certain distance by operating the portable transmitter 4 It is configured to remotely control the opening and closing of the shutter.

  Further, as described above, by performing pairing before use and setting so that only one set of receiving device 3 and transmitting device 4 can be operated as a pair, radio waves from other transmitting devices and receiving devices can be obtained. This prevents erroneous operation due to the remote control and enables reliable remote operation.

  However, when a person who performs remote operation such as a gate or a shutter is only one person carrying the transmission device 4 as in a private house, a pair of the reception device 3 and the transmission device as described above. It is only necessary to pair four, but several people or dozens of people, such as a parking lot of a condominium, such as a condominium, can remotely control one gate, shutter, etc. by different transmission devices 4 When performing the above, pairing with a plurality of transmission devices 4 is required for one reception device 3.

  In other words, as described above, after the identification code L1 of a certain transmission device 4 is stored in the reception device 3, a push button of another transmission device 4 is pressed and operated as shown in FIG. Then, an operation signal formed from another identification code L2 and an operation code M1 is transmitted, and this identification code L2 is stored in the control means 2, whereby pairing of the two transmission devices 4 to one reception device 3 is performed. Is called.

  In the same manner, similarly, the receiving device 3 is configured such that a plurality of different identification codes are stored in the control means 2 by sequentially pressing the push buttons such as the third transmitting device 4 and the fourth transmitting device 4. Discriminates a plurality of transmission devices 4, and a pairing setting is made so that one reception device 3 can be remotely operated by the plurality of transmission devices 4.

  That is, as for the receiving device 3 used in an individual house, the control means 2 only needs to store the identification code of one transmitting device 4, but there are a plurality of receiving devices 3 used in a parking lot of an apartment house. Therefore, the storage capacity of the control means 2 is larger than that for a private house.

  As prior art document information related to the invention of this application, for example, Patent Document 1 is known.

JP 2009-278506 A

  However, in the conventional receiving device 3 and communication system described above, the receiving device 3 used in a parking lot of an apartment house or the like needs to discriminate a plurality of transmitting devices 4, so that the storage capacity of the control means 2 is increased. However, it is more expensive than a personal housing, and several types of receiving devices 3 with different storage capacities of the control means 2 are required, such as for a personal housing and a housing complex, and the manufacturing of the receiving device 3 becomes complicated and troublesome. There was a problem that it would take.

  The present invention solves such a conventional problem, and an object of the present invention is to provide a receiving apparatus that can be easily manufactured and that can be inexpensively and reliably operated remotely.

In order to achieve the above object, the present invention comprises receiving means for receiving an operation signal from a transmission apparatus and control means for discriminating the transmission apparatus based on an identification code in the operation signal. When the receiving device is in a state and one of the receiving devices is in the pairing setting state and the identification code in the operation signal from the transmitting device includes a predetermined common code, the control means Stores the common code, and when the identification code does not include the common code, the control means stores the entire identification code, performs the pairing setting, and determines the number of codes of the common code. der ones that constitute the identification less than the number of codes code, the receiving apparatus so as to determine the transmitting device by the overall the common code or the identification code For example, the two codes at the beginning of the identification code are used as a common code, whereby the control means discriminates the transmission device, so that a plurality of transmission devices can be discriminated without increasing the storage capacity of the control means. Therefore, there is no need to manufacture a plurality of receiving devices having different functions, and therefore, it is possible to obtain a receiving device that is easy to manufacture, can be inexpensively and reliably operated.

  As described above, according to the present invention, it is possible to obtain an advantageous effect that it is possible to realize a receiving apparatus that can be easily manufactured and that can be operated inexpensively and reliably.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

  In addition, the same code | symbol is attached | subjected to the part of the structure same as the structure demonstrated in the term of background art, and detailed description is simplified.

(Embodiment)
FIG. 1 is a block circuit diagram of a communication system according to an embodiment of the present invention, in which 1 is a receiving means such as an antenna, 12 is a control means such as a microcomputer, and a plurality of wiring patterns are formed on the upper and lower surfaces. These are mounted on a printed wiring board (not shown), the receiving means 1 is connected to the control means 12, and the receiving device 13 is configured.

  Reference numeral 4 denotes a portable transmission device, in which a transmission unit 5 such as an antenna, a control unit 6 such as a microcomputer, and switches 7A and 7B are mounted on a wiring board (not shown), and are identified differently for each transmission device. The transmission means 5 and the switches 7A and 7B are connected to the control means 6 in which codes and operation codes are stored.

  Further, these are covered with a substantially box-shaped case made of an insulating resin (not shown), and a push button or the like protruding from the case is attached to the switches 7A and 7B to form the transmission device 4.

  In the case of the receiving device 13 and the transmitting device 4 that perform remote operation using such radio waves, only the receiving device 13 and the predetermined transmitting device 4 are used before use in order to prevent erroneous operation by other transmitting devices and receiving devices. Generally, a setting that enables operation as a pair, so-called pairing, is performed.

  That is, in the above configuration, first, after the receiving device 13 is set in a pairing setting state by a predetermined operation, for example, when the push button for unlocking of the transmitting device 4 to be paired is pressed, for example, the electrical of the switch 7A As shown in the signal code diagram of FIG. 2A, an identification code L1 that is different for each transmission device and an operation code M1 for unlocking the gate are detected. The operation signal formed from is transmitted from the transmission means 5 as a radio wave.

  Then, the receiving means 1 of the receiving device 13 receives this operation signal, and the control means 12 stores a unique identification code L1 for each transmitting device. At this time, the control means 12 is not the entire identification code L1, but in advance. A predetermined predetermined common code, for example, two codes “00” at the head of the identification code L1 is stored as the common code L3, and the pairing setting of the reception device 13 and the transmission device 4 is performed.

  The paired receiving device 13 is mounted at a predetermined location such as a gate or a shutter, and the control means 12 of the receiving device 13 is connected to a battery or an AC power source by a connector or a lead wire (not shown). (Not shown) and a gate lock mechanism (not shown) and a driving means 8 such as a motor for driving opening and closing of the shutter are electrically connected to constitute a communication system.

  In the above configuration, when the switch 7A for unlocking the gate, for example, of the portable transmitter 4 is pressed from a certain distance from the gate, the identification code L1 and the gate unlocking as shown in FIG. An operation signal formed from the operation code M1 is transmitted from the transmission device 4 as a radio wave.

  Then, the receiving means 1 of the receiving device 13 receives this operation signal, the control means 12 determines the common code L3 in the identification code L1 of this operation signal, and the common code L3 is stored at the time of pairing “00”. In this case, a drive signal is output from the control means 12 according to the operation code M1, and the drive means 8 is driven to unlock the gate.

  At this time, instead of the transmission device 4 that has been paired as described above, a push button on another transmission device 4 is pressed to operate with another identification code L2 as shown in FIG. Even when an operation signal formed from the code M1 is transmitted, if the first two codes of the identification code L2 are “00” and are the same as the stored common code L3, the control means 12 And the driving means 8 is driven to unlock the gate.

  In other words, in addition to directly opening and closing the gate and opening and closing the shutter with a mechanical key when approaching the gate and shutter, the gate can be locked and unlocked even from a certain distance by operating the portable transmitter 4 It is configured to remotely control the opening and closing of the shutter.

  In addition, by performing pairing before use as described above and setting so that only the receiving device 13 and the predetermined transmitting device 4 can be operated as a pair, erroneous operation due to radio waves from other transmitting devices and receiving devices. Thus, a reliable remote operation can be performed, and a predetermined common code L3 is stored in the control means 12, so that a plurality of transmission devices 4 can be remotely operated.

  That is, when pairing the receiving device 13 and the predetermined transmitting device 4, the control means 12 does not use the entire identification code L1 or L2 unique to each transmitting device, but a predetermined common code such as the identification code L1 or the like. The two codes “00” at the head of L2 are stored as a common code L3, and at the time of remote operation, one transmitter 13 can be remotely operated by a plurality of transmitters 4 by determining the transmitter by this common code L3. It is configured.

  Therefore, even when several people or dozens of people perform remote operations such as one gate or shutter by different transmission devices 4, such as parking lots of apartment houses such as apartments, If the two codes at the beginning of the identification code of the transmission device 4 are the same code “00” as the common code L3, one reception device 13 can be remotely operated by the plurality of transmission devices 4.

  Further, when performing pairing before use, it is not necessary to sequentially press the plurality of transmitting devices 4 and store the entire plurality of different identification codes in the control means 12, and the two-digit common code L3 is stored. Since it is only necessary to store the data, it is not necessary to increase the storage capacity of the control means 12, and the receiver 13 can be formed at a low cost.

  Further, a single transmission device 4 having the common code L3 performs pairing of the reception device 13 only once, and several or tens of transmission devices 4 having the common code L3 are connected to the reception device 13. Since the receiver 13 and the plurality of transmitters 4 can be manufactured simply by combining them as a set, they are formed so that they can be easily manufactured.

  When the pairing of the receiving device 13 and the transmitting device 4 is performed, if the identification code of the operation signal transmitted from the transmitting device 4 is not the predetermined common code L3, for example, FIG. As shown in the figure, when the first two codes are not "00" but an identification code L4 of "01", the control means 12 does not store this code "01" as a common code, and the entire identification code L4 And pairing setting with the transmission device 4 is performed.

  That is, in this case, the plurality of transmission devices 4 are not paired with the single reception device 13 as described above, but is used for locking and unlocking the gate of a personal house, opening and closing of the shutter, etc. Pairing is performed so that only one transmission device 4 can be remotely operated as a pair with respect to one reception device 13.

  That is, if the identification code L4 of the paired transmitting device 4 is different from a predetermined common code L3, only one set of receiving device 13 and transmitting device 4 can be operated as a pair. Therefore, there is no need to manufacture a plurality of receiving devices 13 having different storage capacities, such as for a private house and for an apartment house. It can also be set for apartment buildings.

  In the above description, the common code L3 determined by the control means 12 has been described as the two codes “00” at the head of the identification code L1 and L2. However, for example, the common code L3 is different for each apartment. The present invention can also be implemented with the above-described configuration or a configuration in which three or four codes are the common code L3.

  As described above, according to the present embodiment, the control unit 12 stores the predetermined common code L3 in the identification code L1 or L2 of the operation signal from the transmission device 4, and the transmission device 4 is controlled by the common code L3. By determining, it is possible to determine a plurality of transmission devices 4 without increasing the storage capacity of the control means 12, and since it is not necessary to manufacture a plurality of reception devices 13 having different storage capacities, it is easy to manufacture, It is possible to obtain a receiving apparatus that can be cheaply and reliably operated.

  The receiving device according to the present invention can be easily manufactured and can be manufactured at low cost and with reliable operation, and is useful mainly for remote operation such as locking and unlocking of a gate and opening and closing of a shutter.
