Description

  The present invention relates to a remote control transmission / reception apparatus mainly used for remote control of various electronic devices.

  In recent years, remote control of various electronic devices installed outdoors or indoors by remote control transmission / reception devices using radio waves has been widely performed, and even if there is a remote location or shielding object, it is reliable. What can be operated is required.

  Such a conventional remote control transmission / reception apparatus will be described with reference to FIGS. 5 and 6. FIG.

  FIG. 5 is a perspective view of a conventional remote control transmission / reception device. In FIG. 5, reference numeral 1 denotes a substantially box-shaped case made of an insulating resin, and a plurality of operation keys provided with switch contacts on the rear side of the case 1. Projecting so as to be movable back and forth, the operating means 2 is formed.

  In the case 1, a wiring board (not shown) having a plurality of wiring patterns formed on the front and rear surfaces is accommodated in the case 1, and an antenna or the like mounted on the wiring board is used by the transmission means 3 or an electronic component such as a microcomputer. Each of the control means 4 is formed to constitute a remote control transmitter 5.

  Reference numeral 6 denotes an electronic device such as a water heater installed outdoors. A remote control receiver 9 formed from a receiving means 7 such as an antenna and a control means 8 such as a microcomputer is housed below the electronic equipment.

  Further, an operation means 10 such as an operation key having a switch contact formed on the rear side is provided on the front surface of the remote control receiver 9, and the remote control receiver 9 and the remote control transmitter 5 constitute a remote control transmission / reception device. Yes.

  In addition, in the case of a remote control transmission / reception device that performs remote operation using such radio waves, the communication range is wide and the radio waves are far away compared to infrared-type devices that remotely control TVs and videos installed indoors. Because of this, other unintended devices may be operated by mistake.

  Therefore, a predetermined authentication means 2 or 10 is operated before use to set a predetermined authentication code, etc., so that only one set of remote control transmitter 5 and remote control receiver 9 can be operated as a pair, so-called After pairing, actual remote control is performed.

  In the above configuration, when an operation key such as temperature switching is pressed among the plurality of operation keys of the operation means 2 of the remote control transmitter 5 from the room, the switch contacts on the rear side are electrically connected and disconnected. This is detected by the control means 4 and, as shown in the signal configuration diagram of FIG. 6, a remote control signal to which an authentication code B set with the remote control receiver 9 is added after an operation code A for temperature switching or the like. Is transmitted as radio waves from the transmission means 3.

  And this is received by the receiving means 7 of the remote control receiver 9, and the control means 8 determines whether or not the authentication code B of the remote control signal is the same as that set. Various operations of the electronic device 6 according to the operation code A, for example, switching of the hot water supply temperature are performed.

  At this time, if the received authentication code B is different from the set one, the control means 8 determines that the remote control signal is from a remote control transmitter different from the paired one, and the hot water temperature is Remote operation such as switching is not performed.

  That is, a pair of remote control transmitter 5 and remote control receiver 9 are first paired, a predetermined authentication code B is set as described above, and the authentication code B stored in each control means 4 and 8 is By configuring the same combination so that it can be operated remotely, it is configured so that other devices will not be erroneously operated even when the remote control signal uses radio waves that reach a relatively long distance. It was a thing.

As prior art document information related to the invention of this application, for example, Patent Document 1 is known.
JP 2005-328244 A

  However, in the above-described conventional remote control transmission / reception apparatus, when the pair of remote control transmitter 5 and remote control receiver 9 is paired, if the same authentication code B as that of other devices is set, one remote control transmission is performed. There is a problem that a plurality of devices may be remotely operated by mistake with respect to the remote control signal transmitted from the machine 5.

  SUMMARY OF THE INVENTION The present invention solves such a conventional problem, and an object thereof is to provide a remote control transmission / reception apparatus that is capable of reliable remote operation without erroneous operation.

  In order to achieve the above object, according to the present invention, the control means of the remote control transmitter encrypts the operation code corresponding to the operation of the operation means into an encryption code, and transmits the encryption code and an analysis code indicating the encrypted content. The control means of the remote control receiver calculates the operation code from these encryption codes and analysis codes, and the control means of the remote control transmitter and the remote control receiver is formed to be rewritable to constitute a remote control transmission / reception device. In addition to transmitting and receiving encrypted operation codes, this encrypted code can be rewritten, so remote control transmission and reception that enables reliable remote operation without different remote control transmitters and different devices being operated remotely It has the effect | action that a device can be obtained.

  As described above, according to the present invention, it is possible to obtain an advantageous effect that it is possible to realize a remote control transmission / reception device that can be operated reliably and without erroneous operation.

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

  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 remote control transmission / reception device according to an embodiment of the present invention, FIG. 2 is a perspective view thereof, and in FIG. 1, 1 is a case made of an insulating resin such as polystyrene or ABS, On the front surface of the case 1, a plurality of operation keys 2A made of rubber or insulating resin with a switch contact provided on the back protrudes so as to be movable back and forth, and an operation means 2 is formed.

  The case 1 contains a wiring board (not shown) such as paper phenol or glass-filled epoxy in which a plurality of wiring patterns are formed on the front and rear surfaces by copper foil or the like, and an antenna mounted on the wiring board The control means 14 formed from the operation code processing unit 14A and the encryption code processing unit 14B is provided by the transmission means 3 and electronic parts such as a microcomputer, respectively, and the connection means such as a connector on the back surface or the side surface of the case 1 15 is formed to configure the remote control transmitter 16.

  An electronic device 6 such as a water heater installed outdoors has a receiving means 7 such as an antenna, a control means 18 formed of an operation code processing unit 18A such as a microcomputer and an encryption code processing unit 18B. The remote control receiver 19 provided with each is housed.

  Further, an operation means 10 such as an operation key having a switch contact formed on the rear side and a connection means 20 such as a connector are provided on the front surface of the remote control receiver 19, and the remote control receiver 19 and the remote control transmitter 16 A remote control transmission / reception device is configured.

  In the above configuration, when an operation key such as temperature switching is pressed among the plurality of operation keys of the operation means 2 of the remote control transmitter 16 from the room, the electrical contact of the rear switch contact is performed, This is detected by the control means 14, and an operation code A of, for example, "0010" formed from 0 and 1 bits for temperature switching as shown in the signal configuration diagram of FIG. The part 14A calculates.

  Then, as shown in FIG. 3B, the operation code A is encrypted by converting the operation code A into, for example, an encryption code C of “1101” obtained by inverting bit 0 to 1 and 1 to 0 as shown in FIG. At the same time, an analysis code D of, for example, “00” indicating the encrypted content is added, and this remote control signal is transmitted as a radio wave from the transmission means 3.

  When the receiving means 7 of the remote control receiver 19 receives this, the received encryption code C of “1101” from the analysis code D of “00” stored in the encryption code processing section 18B by the control means 18 is changed to a bit. While detecting that 0 and 1 are reversed, the operation code processing unit 18A calculates an operation code A of “0010”, and the operation code A is used to perform various operations of the electronic device 6 such as hot water supply temperature. Switching is performed.

  That is, the operation code A corresponding to the operation of the operation means 2 is not transmitted as it is, but the control means 14 of the remote control transmitter 16 encrypts the code into the encryption code C and the analysis code D indicating the encrypted content. Because the remote control signal is transmitted as a remote control signal, the remote control signal has a wider communication range than infrared rays, etc., so that even if a radio wave that reaches a relatively long distance is used, other devices are not operated by this radio wave. Has been.

  That is, the remote operation by the encrypted encryption code C is that the analysis code D is stored in the encryption code processing unit 18B, and the control means 18 can convert the encryption code C into the operation code A. Since only the electronic device 6 provided with the remote control receiver 19 is used, even if the electronic device 6 receives a remote control signal from another remote control transmitter, the electronic device 6 may be remotely operated by mistake. There is no such thing.

  Furthermore, since the remote control transmitter 16 and the remote control receiver 19 are provided with connection means 15 and 20 such as connectors, the rewriting device 21 shown in the perspective view of FIG. The control means 14 and 18 can be rewritten to encryption other than encryption.

  That is, in the figure, reference numeral 22 denotes a substantially box-shaped case made of an insulating resin. On the upper surface of the case 22, a plurality of operation keys 23A and 23B provided with switch contacts below protrude in a vertically movable manner.

  In addition, a wiring board (not shown) having a plurality of wiring patterns formed on the upper and lower surfaces is accommodated in the case 22, and an encryption method is performed by electronic components such as a microcomputer mounted on the upper and lower surfaces of the wiring board. A rewriting device 21 is configured by forming a stored storage means 24 and a cable 26 having one end connected to the wiring board and the other end mounted with a connector 25 extending from the side surface of the case 22.

  First, after the connector 25 of the rewriting device 21 is inserted and connected to the connection means 15 of the remote control transmitter 16, when a predetermined operation key for rewriting, for example, the operation key 2A is pressed, The control means 14 detects this and the encryption code processing unit 14B of the remote control transmitter 16 becomes rewritable.

  Further, when a predetermined operation key for rewriting of the rewriting device 21 such as the operation key 23A is pressed thereafter, data of a predetermined encryption method, for example, bit data is stored from the storage means 24 via the connector 25 or the cable 26. Encrypted data for reversing the arrangement order is sent to the remote control transmitter 16, and the control means 14 stores it in the encryption code processing unit 14B.

  Thereafter, the connector 25 is connected to the connection means 20 of the remote control receiver 19 and the operation means 10 is pressed to make the encryption code processing unit 18B rewritable, and then the same operation as described above is performed. As a result, the same encrypted data as the remote control transmitter 16 is also stored in the control means 18 of the remote control receiver 19.

  Then, when the operation means 2 such as temperature switching of the remote control transmitter 16 rewritten by another encryption method as described above is pressed, the control means 14 detects this, and the same as described above. As shown in FIG. 3A, for example, the operation code processing unit 14A calculates an operation code A of “0010”.

  However, after this, the encryption method of the encryption code processing unit 14B has been rewritten from the encryption method that inverts the bits 0 and 1 to the encryption method that inverts the bit arrangement order. As shown in (c), encryption is performed by converting “0010” into an encryption code E of “0100” arranged in reverse.

  Further, the control means 14 adds an analysis code F of, for example, “01” indicating that this is an encryption method for inverting the bit arrangement order stored in the encryption code processing unit 14B to the encryption code E, This remote control signal is transmitted from the transmission means 3 as a radio wave.

  When this is received by the receiving means 7 of the remote control receiver 19, the encryption code processing unit 18B has also rewritten the encryption method, so that the analysis code “01” stored in the encryption code processing unit 18B by the control means 18 is rewritten. From F, it is detected that the received encryption code E of “0100” is the one in which the bit arrangement order is reversed, and the operation code processing unit 18A calculates the operation code A of “0010”, and this operation code A Thus, the electronic device 6 is operated, for example, the hot water supply temperature is switched.

  That is, by forming the encryption code processing units 14B and 18B of the control means 14 and 18 so as to be rewritable, the operation code A is encrypted into various encryption codes such as the encryption codes C and E, and the remote control transmitter 16 controls the remote control. While being able to transmit a signal, the remote control receiver 19 calculates an operation code A from the analysis codes D and F added thereto, and various remote operations of the electronic device 6 are performed. .

  That is, since the control means 14 or 18 encrypts the operation code A corresponding to the operation of the operation means 2 to the encryption code C or E and transmits / receives it and the encryption code can be rewritten, the remote control signal Even when a radio wave having a wide communication range and reaching a relatively long distance is used, other operations such as remote control of the other device by the remote control transmitter 16 and remote control of the electronic device 6 by the other remote control transmitter are not possible. There is no reliable remote operation.

  In the above description, the rewrite device 21 is connected to the remote control transmitter 16 and the remote control receiver 19, respectively, and the encryption code processing units 14B and 18B of the control means 14 and 18 are rewritten by performing a predetermined operation. However, the rewriting device 21 is used to rewrite only the control means 14, and thereafter, the rewritten encryption method is transmitted to the remote control receiver 19 by a predetermined operation of the remote control transmitter 16, whereby the control means 18 is controlled. The present invention can also be implemented as a rewritten configuration.

  Further, the connection means 15 and 20 of the remote control transmitter 16 and the remote control receiver 19 are not a connector but a card reader, for example, and a memory card or the like on which an encryption method is recorded is attached to the operation means 2 or By performing 10 predetermined operations, the control means 14 and 18 can be rewritten by various other configurations such as a configuration for rewriting the encryption code processing units 14B and 18B.

  Thus, according to the present embodiment, the control means 14 of the remote control transmitter 16 encrypts the operation code corresponding to the operation of the operation means 2 into the encryption code, and the analysis code indicating the encryption code and the encrypted content The control means 18 of the remote control receiver 19 calculates an operation code from these encryption codes and analysis codes, and the control means 14 and 18 are formed to be rewritable, so that different remote control transmitters and It is possible to obtain a remote control transmission / reception device that can be reliably operated without erroneous operation such that different devices are remotely operated.

  In the above description, in order to facilitate understanding of the configuration, the remote control transmitter 16 transmits a remote control signal in which a 2-digit analysis code D, F, or the like is added to a 4-digit encryption code C, E, or the like. As explained above, a bit array with a larger number of digits is actually used, and generally these codes are set by a predetermined header code determined for each device or model, or paired before use. The transmitted authentication code is added and transmission / reception is performed.

  In the above description, the configuration in which transmission is performed only in one direction from the remote control transmitter 16 to the remote control receiver 19 has been described. However, the remote control transmitter 16 is provided with reception means, and the remote control receiver 19 is provided with transmission means. It is possible to implement the present invention even if they are configured to transmit and receive each other.

  Furthermore, although the hot water heater installed outdoors has been described as an example of the electronic device 6 to be remotely operated, a configuration for remotely operating an air conditioner installed in a remote place indoors or in another room, a television, a video, or the like It is good.

  The remote control transmission / reception apparatus according to the present invention is capable of reliable remote operation without any erroneous operation, and is useful mainly for operation of various electronic devices.
