Embodiment 1 FIG.
FIG. 1 is a schematic configuration diagram including a reader / writer which is an information transmission apparatus according to the first embodiment of the present invention, and a recording medium provided in a device which communicates information with the reader / writer. A device 9 such as a refrigerator or an air conditioner is provided so that device information can be transmitted and received from the outside of the device, such as a recording medium 16 such as a wireless tag or an IC card attached to the surface of the device body. Further, power is transmitted and received between the reader / writer 1 and the device side by radio waves from the device power source, and the power is transmitted from the reader / writer 1 to the device, or from the reader / writer 1 that has received power to the recording medium 16. Make it possible to transmit and receive power unidirectionally and bidirectionally, such as enabling transmission by radio waves, or returning power from the reader / writer 1 to the transmission / reception means 10 on the device side again. Yes.

  In order to be able to transmit and receive information communication between the device 9 and the reader / writer 1, for example, a transmission / reception means 10 having an antenna and a device for controlling communication is provided on the device 9 side, and the reader / writer 1 side is also provided. A similar configuration is provided. Note that the reader / writer 1 communicates with the recording medium 16 such as a wireless tag or an IC card or with the device 9, and information added to the recording medium 16 from the beginning, for example, history of the device 9 or operation data. Alternatively, the information stored at the time of design and production such as the type of harmful material necessary for recycling, the removal method, and the device disassembly method is read, or the operation data of the device 9 is received from the device and stored in the recording medium 16. It has a function to write newly added information. That is, information can be freely transmitted between the device 9, the reader / writer 1, and the recording medium 16.

  Next, the operation of transmitting and receiving information in the configuration of FIG. 1 will be described with reference to FIG. FIG. 2 is a flowchart for explaining the operation of information communication. When the device 9 is turned on and started (ST1), the reader / writer 1 is supplied with power from the device 9 via the power transmitting / receiving means (ST2). The recording medium 16 receives power by radio waves via an antenna provided in the wireless tag, supplies this power to the IC (ST3), and starts up (ST4). The IC determines whether or not writing is performed by a microcomputer (ST5). If YES, information communication is performed from the control device via the antenna of the reader / writer 1 (ST6), and information sent from the recording medium 16 is transmitted. Is stored in the circuit IC (ST7). On the other hand, if it is determined whether or not to write (ST5) NO, the recording medium 16 transmits information (ST8), and the reader / writer 1 receives information from the control device via the antenna (ST9). As described above, transmission / reception is performed until the end (ST10), and information transmission between the reader / writer 1 and the recording medium can be performed in a non-contact manner by radio waves.

  Next, the power transmission / reception of power will be described with reference to the circuit configuration diagram of FIG. The power supply port 19 of the device 9 is connected to the power supply 20 in a wired manner. When the switch opening / closing means 14 is closed and connected to a load inside the device, power is supplied to the device driving device 15 and the power transmitting / receiving device 12. As a result, for example, the air conditioner indoor unit can be operated, power can be supplied to the reader / writer 1, and information can be transmitted to the recording medium 16 using the reader / writer 1. The switch opening / closing means 14 receives a power on / off signal from an external remote control device or the like, or the control device 11 operates the relay of the switch opening / closing means 14 to open / close by a manual switch signal provided in the device 9. The device 9 is provided with power / information transmission / reception means 10 such as an antenna, and transmits / receives power from the power transmission / reception device 12 and information stored in the storage device 13 and determined by the control device 11.

  The power / information transmission / reception means 10 provided in the device 9 transmits and receives radio waves. First, it is affixed to the surface of the device 9 to exchange the radio waves, and stores specific information. And secondly, the information recorded in the IC 18 provided in the main body of the recording medium 16 is read out, or is provided in the main body of the recording medium 16 based on the information transmitted from the device side. There is a reader / writer 1 that can rewrite a record of the IC 18 as a storage means, or perform both reading and writing. The devices 1 and 16 that are objects to exchange radio waves such as the first and second power transmission / reception and are information transmission devices have power / information transmission / reception means 17 and 2 such as antennas. Yes. In the main body of the reader / writer 1 which is a kind of information transmission device, there is a storage device 5 for storing information, a control device 3 for controlling exchange of the stored information, and a power transmission / reception device 4 for controlling power transmission / reception. Is provided.

  The reader / writer 1 shown in FIG. 3 has a structure in which a power supply port 8 connected to an external power source and a charging means 7 including a battery can supply power to each device of the reader / writer 1 via a switch 6. However, when adopting a system in which all power necessary for the reader / writer 1 is transmitted from the device 9 side, these power supply means are unnecessary. Therefore, the reader / writer 1 can be made small and light, and can be used anytime and anywhere where electric power can be received by radio waves. However, it is a matter of course that you can use the power from the battery that is charged by manually turning on the switch if necessary, such as when you can not receive power well or the power is insufficient, etc. .

  That is, the reader / writer 1 communicates between the device 9 and the reader / writer 1 through the power / information transmitting / receiving means 10 and 2 of the device controller 11 and the reader / writer main body controller 3, respectively. Service records such as device operation records, such as the set temperature status and power consumption of the air conditioner 9, the number of compressor start / stop cycles of the refrigeration cycle and the refrigerant pressure status, measurement records and write data in the service inspection mode, etc. The time record can be obtained by operating the switch opening / closing means 14 even when the device is stopped or in operation. Further, information such as operation records temporarily stored in the reader / writer main body storage device 5 is directly communicated between the reader / writer main body control device 3 and the recording medium IC 18 of the recording medium 16 such as a tag. Writing to the storage means 18 of the recording medium is performed. Also, the product specifications and design data stored in the storage means 18 of the recording medium are read by the reader / writer during recycling via the power / information transmission / reception means 2 and 10 of both transmission / reception means, and input to another personal computer. It is possible to take a structural drawing and use it to determine how to destroy the product.

  The information transmission apparatus 1 that is a reader / writer used for the exchange of information with the device 9 and the exchange of information with the recording medium 16 receives power from the transmission / reception unit of the device 9 as well as information communication. -Since power is also received by radio waves via the information transmission / reception means 2 and 10, power supply by wire or the like and standby power are not required. In other words, the reader / writer 1 is wirelessly attached to a recording medium 16 such as a wireless tag that can be affixed to the device 9 and that can write and read various information of the device 9 and an IC card that is inserted into or attached to the device. Sending and receiving of various devices that have non-contact writing and reading functions, etc., that is, not only the device to which the tag is attached, but also a device that is adjacent and connected to an external power supply and can transmit power wirelessly It is possible to receive power by radio waves from the unit, and to receive power and exchange information with the tag of the device by communication without using a wired or other direct power supply.

  As shown in FIG. 3, the power / information transmission / reception means 17 of the recording medium 16 attached to the device or the IC 18 which is a storage device and the device 9 can directly exchange power and data by radio waves. As described above, the present invention provides all information by simply supplying power from the device side to the recording medium 16 such as a reader / writer 1 and a passive wireless tag that do not have a specific power source or a connected power source. Transmission can be made possible, and a system can be obtained by using the necessary power when necessary.

  FIG. 3 shows a configuration in which power is transmitted from a power source 20 connected to the device 9 to the reader / writer device main body 1 by communication radio waves, and household appliances such as an air conditioner indoor unit and a refrigerator that are always connected to the power source. 9 has a refrigeration cycle for air conditioning and refrigeration, and the compressor of this refrigeration cycle is driven by a motor. Furthermore, the fan which ventilates is also driven by a motor and used for driving power and control power by using AC from a commercial power source wired to each household. That is, the power is supplied from the power source 20 to each device driving device 15 via the power port 19, and the control device 11 and the storage device 13 are also used as a control power source for devices such as arithmetic processing devices and via the power transmission / reception device 12. Of course, it may be used as a power source for the tag 16 as a recording medium via the power / information transmitting / receiving means 10 and 17 as shown in FIG. In addition, the device 9 is provided with a power transmission / reception device 12, and this power is transmitted from the power / information transmission / reception means 10 to the outside of the device 9 by radio waves.

  In the circuit configuration diagram shown in FIG. 3, the circuit is cut from the power supply 20 to the device driving device 15 so that it is not always supplied by the switch opening / closing means 14 that opens and closes the power transmission switch. As a result, it is not necessary to provide a power source on the information transmission device side of the reader / writer 1 or the recording medium 16, and furthermore, the device drive device 15 in the device is powered until the switch opening / closing means is closed. Generation of standby power related to power transmission / reception as well as standby power of the device driving apparatus, for example, can be prevented. When transmitting power via radio waves, it is unclear when it is necessary to connect the power supply and wait when the air conditioning is not used or when it is necessary for inspection services. Although there is a problem of continuing consumption, this invention can solve this problem and achieve energy saving. In addition, the device drive device can be operated as a device drive device, for example, when the air conditioner indoor unit is serviced or when the refrigerant is processed during recycling. However, the device drive device is in standby for the device involved in the original normal operation such as cooling. Of course, another circuit may be provided if desired.

  Although it has been described that the switch 14 can be opened and closed by a power on / off switch or the like provided in a remote control device that can stop the operation of the device 9, for example, the information transmission device 1 controls operation stop, temperature adjustment, operation mode switching, etc. The remote control function and the information reading / writing function for the recording medium 16 described above can be integrated, that is, the remote control device and the reader / writer 1 can be integrated. The storage device 3 of the information transmission device 1 stores data necessary for a remote control function for controlling operation stop, temperature adjustment, operation mode switching, etc. of the device, and the control device 3 can control the remote control function. Keep it. Further, it is assumed that it can be always driven by a battery as in a normal remote control device. In the case of this configuration, the power switch of the information transmission device 1 is turned on, and the power of the battery provided in the information transmission device 1 is used to connect the power transmission / reception device 4 and the power / information transmission / reception means 2 directly connected to the battery. The control information is transmitted from the information transmission device 1 side to the device side via the control device 3 connected in a closed state with the radio wave, and the control information is transmitted from the power transmission / reception means 10 within the device 9. The switch opening / closing means is operated through the device.

  That is, the battery capacity of the information transmission device 1 may be only the power for operating the switch opening / closing means 14 provided in the device 9, and when the switch opening / closing means is in the closed state, the power from the power source 20 connected to the device 9 thereafter. Thus, the power used for the device drive device 15 and the control device 11 in the device 9, the power used for the control device in the information transmission device main body 1, and the power required for the recording medium 16 are as described above. Will be supplied from the side. Of course, the battery of the information transmission device may be used together, or when the power transfer is interrupted due to poor communication, the battery is automatically switched to the battery. Further, the remote controller that is generally used and always at hand can read or write information in the recording medium 16, and the service person does not need to carry a special reader / writer device. Anyone can read the record, and if there is a need to avoid sending or receiving power or writing to the recording medium, perform a special procedure on the device operation switch such as switching the mode of the remote control. It is only necessary to provide means capable of being treated by software so that a specific person such as a service person can perform the writer function. In this way, the standby power of the device 9 is not required, the battery of the information transmission device 1 is not required to operate the device as well as the standby power for power transmission / reception, and the switch opening / closing means connected to the power source provided in the device 9 is provided. Since it is necessary to operate, that is, only triggers for all the operations are required, a device having a simple structure and low energy consumption can be obtained.

  With reference to the circuit configuration diagram of FIG. 4, the operation of opening and closing the switch using the information transmission device 1 as a reader / writer device as a trigger will be described. 4 has the same configuration as that of FIG. 1, and the switch opening / closing means 14 serving as the power transmission switch turns on the remote control 1 by, for example, turning on the power switch of the remote control 1 by trigger power transmission from the reader / writer device 1 as described above. By operating the provided switch 6 and supplying power to the device control device via the power / information transmitting / receiving means 2 and 10 according to an instruction from the control device 3, the switch is turned on and the circuit is connected, and power is sent to each device. .

  The electric power from the power source on the device side is sent to the power transmission / reception means 16 via the switch opening / closing means 14 and further via the power transmission / reception apparatus, and the power is transmitted to the remote controller 1. As a result, the information transmission apparatus 1 can instruct the operation operation of the device as a remote controller to the device in a non-contact manner and can perform reading and writing from the necessary recording medium 16. As a result, no standby power is required until the device 9, the information transmission device 1, or the recording medium 16 is triggered. Therefore, standby power is not required until normal operation, for example, until it is operated by a service person who repairs the device, for example, until it is operated, or when the device is discarded, even if the power is turned on at the recycling plant. There is no need to wait until the remote control is turned on.

  Instead of the switch 6 provided in the information transmission device as the trigger, a mechanism for operating the switch opening / closing means 14 may be provided in the information transmission device 1. For example, a permanent magnet is provided in the information transmission device 1, and a coil connected to a relay for a power transmission switch of the device 9 is arranged at a specific position such as a surface portion of the device 9, and near this coil. When the reader / writer device 1 is brought, the magnetic force generated from the magnet acts on the coil on the device side in a non-contact manner to generate an induced voltage. A relay or the like connected to the coil receives and sets a voltage to turn on the power transmission switch 14 to connect the circuit. Even if the trigger of this relay set is not a combination of a magnet and an induction coil, for example, a mechanism for bringing the reader / writer device 1 into contact with the device 9, that is, a potential and a capacity are directly provided in the device like a battery or a capacitor provided in the reader / writer device. The trigger mechanism is contacted with the trigger terminal to operate the relay mechanism using a change in potential or capacitance as a trigger, or the protrusion provided on the information transmission device 1 is inserted into the recess of the device 9 to release the mechanical trigger. But it ’s okay. That is, when the reader / writer device 1 is brought close to the device 9 that receives power, or is brought into contact with the reader / writer device 1 to operate the switch opening / closing means 14 that is a power transmission switch, power transfer is enabled, so that Unnecessary power is not necessary, and it is not necessary to connect a wire to the reader / writer device or provide a special power source that requires replacement.

  The reader / writer 1 receives the power transmitted from the device 9 by the power / information transmission / reception means 2, stores it as the power of the main body 1 in the charging means provided in the power transmission / reception device 4, and directly uses it as the power source of the storage device 5. Or used for a short time for information communication of the main body control device 3. It should be noted that the port 8 that can be supplied with power from other sources or the charge is used for cases where a small amount of power is continuously required to be stored in the memory for a long period of time, when power cannot be supplied by the transmission / reception unit 4, or when power is insufficient. A configuration including a possible battery 7 may be used. In this case, the power from both the port 8 and the power transmission / reception device 4 can be switched and stored, or separate power storage means can be provided.

  The present invention does not need to receive power only from the device 9 to which the tag is attached as in the configuration shown in FIG. 1, and can transmit power from various devices capable of power transmission by radio waves. It is only necessary to have a configuration capable of transmitting and receiving power with the trigger mechanism, and a configuration capable of transmitting and receiving power with the relay mechanism on the device side as well, and the main body capable of exchanging information with the recording medium is brought close to or in contact with such devices anywhere Thus, the power transmission switch can be opened and closed, so that it is possible to obtain an easy-to-handle information transmission apparatus or information transmission method that can obtain power anywhere and save unnecessary power. The relay mechanism when receiving the trigger of the switch opening / closing means 14 provided in the device is configured so that the power transmission switch 14 can be turned on and off alternately, so that power can be conveyed by bringing it closer or in contact with the reader / writer. It is possible to set the power to zero and automatically set the standby power to zero because it is triggered again by turning it away or pulling it off. When an on-trigger is applied and electric power is received and stored, the reader / writer device can be informed that the electric power is alive, for example, by using an indicator lamp. Thereby, not only energy saving but also an information transmission device that is easy to handle and can be reliably operated is obtained. This display may be a power connection indicator lamp of the device, or may be displayed on both the device side and the information transmission device side.

  In the above example, an example of the structure of power transmission by radio waves using power / information transmission / reception means has been described. However, the power transmission / reception devices 4 and 12 should be replaced with power supply systems such as electromagnetic induction, light, and sound as well as radio waves. Can do. For example, the power transmitting / receiving device 12 that transmits power may emit infrared light, and the power transmitting / receiving device 4 that receives power may use a photoelectric element that changes light into electricity. The photoelectric element can be freely used to change electricity to light and use it for power transmission, or change light to electricity and use it for power reception, or to use it in both directions. The same applies to transmission / reception by radio waves for communicating information using the power / information transmission / reception means.

  Even if many recording media 16 such as tags come into the home, if the information transmission device 1 of the present invention is used, power is easily supplied for control, output circuit, etc. Since it can be written / read and can be moved and detached, various types of devices and recording media in various places can be judged and written / read. Furthermore, if the power transmission / reception device 12 is configured so that it can be used in common with the remote control 1 provided in large equipment such as a refrigerator as standard, it can be used as it is for many devices in the home and recycled when the large equipment is discarded. Information such as useful materials and harmful materials written on the wireless tag can be easily and effectively recycled using a commercially available remote control or a simple reader / writer. In addition, if a reader / writer device can be used easily at any time, such as at home, and if the battery used for this information transmission device displays a shortage of capacity, etc., a large-scale device in any home, for example, always energized It can be used in any household appliance such as a hot-water supply by charging with a refrigerator.

  That is, by providing the manual switch 6 or the like for connection with a battery or the like as the power source of the reader / writer device 1, the power source can be turned off when the information transmission device such as the reader / writer device is not used. Furthermore, the power transmission / reception device 4 is provided in the reader / writer 1 that is charged, and the necessary trigger power for turning on the transmission switch 14 can be supplied from the reader / writer device 1 to the device 9. If the manual switch 6 is turned on and used only at the time of supply, the battery 7 does not waste power. As a trigger for turning on the transmission switch 14 provided in the device 9, the switch opening / closing means which is a trigger mechanism on the reader / writer device main body 1 side is the battery 7, the manual switch 6, and the power transmission / reception devices 4, 2. The relay mechanism for turning on the transmission switch 14 as the opening / closing means may be operated by connecting the power source by operating the relay mechanism with the power received from the power / information transmitting / receiving means 10 in the power transmitting / receiving devices 10 and 11. As a result, the standby voltage for receiving the activation signal can be eliminated by any device 9 or reader / writer device 1 and can be widely used in general. Of course, the switch opening and closing means for opening and closing the power source of the reader / writer device 1 and the device 9 main body may be used together with a manual switch or the like. Of course, it can be done.

  Power transmission / information transmission / reception means, trigger mechanism, and relay mechanism are provided in information transmission devices such as devices and reader / writer devices in any device and its information transmission device, for example, air conditioners, refrigerators, lighting equipment, power supply equipment having breakers, etc. In this way, it is possible to supply power with information from the transmitter / receiver of various devices by using radio waves, and there is no need to connect to a direct external power source such as a wired connection. Make it unnecessary. Also, a reader / writer with a function for writing / reading information to / from a recording medium such as a wireless tag or IC card that can write / read information pasted on the device is supplied with electric power from the transmission / reception unit of the device body, and is wired, etc. Eliminates power supply.

  Although the present invention has been described with the device 9 for home appliances, the reader / writer device 1 and the recording medium 16 such as a wireless tag, the recording medium 16 such as an IC card used for the information device 9 has been described. In this case, in normal use, information exchange and power transfer are often performed only between the information device 9 and the IC card 16. This case will be described with reference to the circuit configuration diagram of FIG. For example, even if the present invention does not use the reader / writer main unit 1, that is, the IC card 16 includes the IC 18 including the power transmission / reception device and the power / information transmission / reception means 17, and the recording medium transmission / reception unit 17 performs the information communication and power transmission / reception. What is performed with the power / transmission / reception means 10 of the device 1 is naturally as described in FIGS. 1 to 4 and described above.

  If the RFID tag RFID described with reference to FIGS. 1 to 4 is an ID card 16 that is used in a state where it is removed from the information device 9 such as an ID card confirmation device, the ID card 16 receives wireless information as power. Information can be written or read between the information transmitting / receiving means 10 and 17. In the recording medium 16 such as an ID card used for history management at the time of entry / exit, the recording medium transmission / reception means 17 and information are stored in the recording medium 16 capable of transmitting / receiving this information to / from the outside without contact. An IC 18 including a recording medium storage means provided in the recording medium is provided. Electric power transmitted from the outside of the recording medium 16 serving as a power source is received in a non-contact manner and consumed in the same manner as the recording medium IC 18. The power of the power source connected to and used by the information device 9 is transmitted from the device 9 to the recording medium. As shown in FIG. 5, a trigger mechanism that serves as a trigger for opening and closing the switch opening / closing means 14 provided on the device 1 side. The recording medium switch opening / closing means 22 is provided on the recording medium 16.
