Description

  The present invention includes an electronic device that exhibits a predetermined function by operation of an electronic circuit, a setting diagnostic device that performs setting or diagnosis of the electronic device, a setting diagnostic system that includes the electronic device and the setting diagnostic device, and the electronic device. The present invention relates to an air conditioner, a sensor device, a measuring instrument, and an electric device.

  A non-contact setting system that sets data in a network terminal device in a non-contact manner using a setting device has been disclosed (for example, see Patent Document 1). In this non-contact setting system, the setting device includes a primary coil, and the terminal device includes a secondary coil. Power is supplied from the setting device to the terminal device via the primary and secondary coils. Thereby, even if the power supply device is not connected to the terminal device, power is supplied from the setting device to the terminal device, so that data setting work can be performed.

  In addition, an electric device that sets specifications by writing information received from the outside into a control unit using an RFID (Radio Frequency Identification) system is disclosed (for example, see Patent Document 2). In this electric device, a tag connected to a control unit that controls each component of the electric device is attached to the casing. At the shipping destination, the reader / writer transmits information defining operating conditions such as display means and driving means constituting the electric device to the control unit via the tag. The control unit controls the display unit and the driving unit according to the information.

  In this electrical device, information can be exchanged only by a combination of a specific tag and reader / writer, so that information leakage can be prevented.

  In the non-contact setting system according to Patent Document 1, it is necessary for the setting device to supply power to the terminal device to operate the entire terminal device while setting data. Although only setting information is set, power is supplied to a portion that does not need to operate, so that power is wasted. Furthermore, power is also supplied to the main function portion on the apparatus side, and the safety of the setting work may be reduced by operating that portion. In addition, since the setting device needs to supply power necessary to operate the entire terminal device, the setting device becomes large and expensive.

  In the electric device described in Patent Document 2, since RFID is used, information set in the electric device can be easily confirmed and changed, and information leakage can be prevented. However, in this electrical device, since a tag is interposed between the control unit of the electrical device and the reader / writer, in order to transmit information held by the control unit to the reader / writer, the reader / writer is used in the electrical device. The information needs to be converted according to the communication specification between the tag and the tag.

  Such conversion leads to an increase in the processing burden on the electrical equipment. If a large amount of data such as the measurement result of the operation state and the log of the operation state is converted and transmitted in real time, the processing load of the electric device increases.

  Further, in the electric device described in Patent Document 2, an RFID tag and an interface for connecting the tag and the control unit are necessary for the electric device, so that the cost of the electric device increases.

  The present invention has been made in view of the above circumstances, and its object is to prevent leakage of information without increasing power consumption, cost, and processing burden, and without increasing the size of the apparatus. To provide an electronic device, a setting diagnosis device, a setting diagnosis system, an air conditioner, a sensor device, a measuring instrument, and an electric device that can easily perform setting and diagnosis of the electronic device.

  In order to achieve the above object, in the electronic apparatus according to the present invention, the main function unit performs a normal operation for exhibiting a predetermined function. The power supply circuit converts an AC voltage supplied from an external power source into a DC voltage. The first coil receives electric power from the outside by electromagnetic induction coupling. The power receiving circuit receives AC power received via the first coil and converts the AC power into DC power. The second coil transmits and receives information to and from the outside by electromagnetic induction coupling. The transmission / reception circuit transmits / receives information via the second coil. The storage unit stores information transmitted / received by the transmission / reception circuit. The first power supply path supplies the DC voltage converted by the power supply circuit to the main function unit, the transmission / reception circuit, and the storage unit. The second power supply path supplies the DC power converted by the power receiving circuit to the transmission / reception circuit and the storage unit.

  According to the present invention, the power supplied from the external power source and converted by the power supply circuit is supplied to the entire electronic device, while the power received and converted by the first coil and the power receiving circuit is the transmission / reception circuit, To the storage unit. As a result, the range in which the electronic device operates can be limited to the required range according to the state of power supply to the electronic device, so the power consumption and cost of the electronic device and the setting diagnosis device can be reduced, and Miniaturization can be realized.

  Further, according to the present invention, it is possible to exchange information with the outside through a transmission / reception circuit in a contactless manner. This eliminates the need to incorporate a tag and an interface for connecting the tag and the control unit into the electronic device, thereby suppressing increase in power consumption and cost. In addition, information exchange by electromagnetic inductive coupling is performed at a close distance, so that information leakage can be prevented.

  In addition, when exchanging information, it is not necessary to perform special conversion in accordance with the communication specification by the microprocessor, so that the processing load on the electronic device can be reduced. In addition, even when power is not supplied from an external power source, power can be received using the power receiving circuit and information can be exchanged with the outside.

  Further, according to the present invention, the external device can function as the input / output unit, so that the input / output unit is not necessary. As a result, power consumption, cost, and processing burden can be reduced.

  As described above, according to the present invention, it is possible to set or diagnose an electronic device while preventing leakage of information without increasing power consumption, cost, and processing burden, and without increasing the size of the device. Can be done easily

  The I / F circuit 30 is a communication interface for connecting the electronic device 21 to another electronic device. Here, as a communication method of the I / F circuit 30, a LAN (Local Area Network), RS-232C, and RS-485 are used as wires, and a wireless LAN, UWB (Ultra Wide Band), ZigBee, Bluetooth, and specific power saving are used.

  As described above, the diagnostic device 1 includes the power feeding coil 2, and the electronic device 21 includes the power receiving coil 22. The power feeding coil 2 and the power receiving coil 22 face each other.

  When a current flows through the power feeding coil 2, the power receiving coil 22 is connected by electromagnetic induction coupling, and power is supplied from the setting diagnosis device 1 to the electronic device 21 without having an electrical contact with each other.

  Here, the power supply state determination unit 8 will be described in detail.

  In a normal state, the electronic device 21 operates with power supplied from the external power source 35. The electronic device 21 cannot perform normal operation when the external power supply 35 is not connected.

  The power supply state determination unit 8 acquires power supply information of the external power source 35 from the electronic device 21 and determines whether power is supplied to the electronic device 21 based on the acquired power supply information. The power supply information is information indicating whether the electronic device 21 is supplied with power from the external power supply 35.

  When the power supply state determination unit 8 determines that the electronic device 21 is not supplied with power from the external power supply 35, the control unit 7 causes the power supply circuit 3 to supply power to the power supply coil 2. The AC power supplied to the power feeding coil 2 is received by the power receiving circuit 23 via the power receiving coil 22, converted into a DC voltage, and output to the power circuit 28. The DC voltage obtained by the power supply circuit 28 is supplied to the transmission circuit 25, the reception circuit 26, the control unit 27, and the memory 29 via the power supply path 34.

  If the power supply state determination unit 8 determines that the electronic device 21 is supplied with power from the external power supply 35, it is not necessary to supply power to the electronic device 21, so the control unit 7 connects the power supply circuit 3 to the power supply coil 2. Stop the power supply.

  As described above, the setting diagnosis apparatus 1 can supply power to the electronic device 21 according to the determination result of the power supply state determination unit 8.

The power receiving circuit 23 includes a resonance capacitor 50, an AC / DC conversion circuit 51, a smoothing capacitor 52, and a DC voltage output terminal 53.

  A DC voltage output from the power supply circuit 12 is applied to the DC voltage input terminal 40.

  The DC / AC converter circuit 41 includes a plurality of switching elements 41P and 41N. The switching elements 41P and 41N are alternately turned on / off in accordance with the drive signals input from the terminals 43P and 43N of the drive signal input unit 43, so that the DC voltage input to the DC voltage input terminal 40 is AC. Converted to voltage.

  The AC power obtained by the DC / AC conversion circuit 41 is supplied to the feeding coil 2 via the resonance capacitor 42. Drive signals input from the terminals 43 </ b> P and 43 </ b> N of the drive signal input unit 43 are supplied from the control unit 7.

  As a circuit configuration of the DC / AC converter circuit 41, as shown in FIG. 2, a half-bridge system is adopted. However, it is also possible to adopt a full bridge method.

  The AC power supplied to the power feeding coil 2 is transmitted to the power receiving coil 22 by electromagnetic induction between the power feeding coil 2 and the power receiving coil 22. The AC voltage generated in the receiving coil 22 by the transmitted AC power is converted into a DC voltage by the AC / DC conversion circuit 51 and the smoothing capacitor 52 via the resonance capacitor 50, and output from the DC power output unit 50.

  As the AC / DC converter circuit 51, as shown in FIG. 2, a full-wave rectifier circuit system comprising a diode bridge is employed. However, you may make it employ | adopt a half-wave rectifier circuit system.

  The resonant capacitors 42 and 50 are used to increase the voltage on the output side by utilizing the resonance phenomenon of the electronic circuit. If these are used, the efficiency of electromagnetic inductive coupling can be improved. Here, the resonance capacitor 42 is a series resonance system, and the resonance capacitor 50 is a parallel resonance system. However, either the series resonance method or the parallel resonance method may be adopted depending on the circuit to be used and the use environment.

  Next, the transmission / reception system of the setting diagnosis system 200, that is, the circuit configuration of the transmission circuit 5, the reception circuit 6, the transmission circuit 25, and the reception circuit 26 will be described in more detail.

  First, the configuration of the transmission circuit 5 will be described. As shown in FIG. 3, the transmission circuit 5 includes a transmission signal input terminal 61, a carrier wave generation unit 62, a modulation circuit 63, and a resonance capacitor 64.

  The transmission signal input terminal 61 inputs the transmitted serial signal. The carrier wave generation unit 62 generates a rectangular wave signal that is a carrier wave of a predetermined frequency. The modulation circuit 63 modulates the serial signal input from the transmission signal input terminal 61 using a rectangular wave signal. The resonant capacitor 64 generates resonance for the same frequency component as the rectangular wave signal. The resonance capacitor 64 can improve the quality factor of the transmission / reception circuit.

  Next, the configuration of the receiving circuit 6 will be described. The reception circuit 6 includes a detection circuit 65, a demodulation circuit 66, and a reception signal output terminal 67.

  The detection circuit 65 removes the carrier wave component from the signal received by the coil 2 (voltage signal induced by the coil 2). The demodulation circuit 66 demodulates the serial signal from the signal output from the detection circuit 65. The reception signal output terminal 67 outputs the serial signal demodulated by the demodulation circuit 66.

  The transmission circuit 25 and the reception circuit 26 are arranged symmetrically with the transmission circuit 5 and the reception circuit 6. The configuration and operation of the transmission circuit 25, that is, the transmission signal input terminal 61, the carrier wave generation unit 62, the modulation circuit 63, and the resonance capacitor 64 are the same as those of the transmission circuit 5. The configuration and operation of the reception circuit 26, that is, the detection circuit 65, the demodulation circuit 66, and the reception signal output terminal 67 are the same as those of the reception circuit 6.

  Here, operations of the transmission circuits 5 and 25 and the reception circuits 6 and 26 will be described with reference to FIG. At the time of transmission, the serial signal input from the transmission signal input terminal 61 is modulated by the modulation circuit 63 using the rectangular wave signal having a predetermined frequency output from the carrier wave generation unit 62 and transmitted to the transmission / reception coil 4.

  At this time, an induced voltage corresponding to the serial signal is generated in the transmission / reception coil 24 electromagnetically coupled by electromagnetic induction. The signal based on the induced voltage is converted into a serial signal after removal of the carrier wave component in the detection circuit 65 of the reception circuit 26 and demodulation in the demodulation circuit 66, and is output to the control unit 27 via the reception signal output terminal 67. In this way, the serial signal is transmitted from the setting diagnosis device 1 to the electronic device 21.

  Further, in the transmission circuit 25, at the time of transmission, the serial signal input from the transmission signal input terminal 61 is modulated by the modulation circuit 63 using a rectangular wave signal having a predetermined frequency generated by the carrier wave generation unit 62, and the coil 24.

  When the modulated serial signal is transmitted to the coil 24, an induced voltage corresponding to the serial signal is generated in the coil 4 coupled by electromagnetic induction. The signal based on the induced voltage is converted into a serial signal after removal of the carrier wave component in the detection circuit 65 of the reception circuit 6 and demodulation in the demodulation circuit 66, and is output to the control unit 7 via the reception signal output terminal 67. In this way, the serial signal is transmitted from the electronic device 21 to the setting diagnosis device 1.

  As a communication system of the transmission circuit 5, the reception circuit 6, the transmission circuit 25, and the reception circuit 26, an amplitude modulation system (ASK, Amplitude Shift Keying) system is adopted. If the ASK method is adopted, the circuit configuration of the transmission / reception system can be made relatively simple as shown in FIG.

  For example, when a digital signal that changes as 1, 0, 1 as shown in FIG. 4A is transmitted, in the ASK system, the transmitted signal is as shown in FIG. 4B, for example. As shown in FIG. 4B, the ASK method is a method of expressing 1 and 0 by changing the amplitude of the carrier wave. The ASK method is characterized in that the communication quality deteriorates when noise of an amplitude component is superimposed on a signal due to the influence of external noise or the like.

  Other methods for improving communication quality than this include an FSK (Frequency Shift Keying) method as shown in FIG. 4C and a PSK (Phase Shift Keying) method as shown in FIG. Any method may be adopted. The FSK method is a method for expressing 1, 0 by changing the frequency of the carrier wave, and the PSK method is a method for expressing 1, 0 by changing the frequency of the carrier wave.

  Next, the arrangement of the power feeding coil 2 and the transmission / reception coil 4 and the arrangement of the power reception coil 22 and the transmission / reception coil 24 will be described. Here, the power supply coil 2 and the power reception coil 22 are described as “power coils”, and the transmission / reception coil 4 and the transmission / reception coil 24 are described as communication coils.

  FIGS. 5A to 5H show arrangement examples of sets of power coils and communication coils. In the arrangement examples shown in FIGS. 5A to 5H, either the left or right coil may be used as the power coil. In any case, between the setting diagnosis device 1 and the electronic device 21, the power coils and the communication coils are arranged so as to face each other.

  5A to 5H, a coil arranged so that the length direction of the coil is perpendicular to the mounting surface of the coil is shown as a coil A. FIG. A coil arranged so that its length direction is horizontal with respect to the mounting surface is shown as a coil B. Coil A and coil B are solenoidal coils.

  It is necessary to arrange the power coil and the communication coil in a state in which a distance that eliminates the influence of interference is maintained so that mutual interference does not occur. For example, FIGS. 5 (A), 5 (D), and 5 (E) show examples in which coils having the same shape are arranged in the same direction. These are generated from the coils of each other. In order to prevent interference between magnetic fluxes, it is necessary to provide a sufficient distance between the coils or to provide a magnetic shield so as not to cause interference.

  In addition, when adopting the arrangement shown in FIGS. 5A, 5D, and 5E and shortening the distance between the coils, different frequencies may be used for power and communication.

  Further, as shown in FIGS. 5B, 5C, and 5F, if the coils are arranged at positions where the directions of magnetic flux generated by the coils are orthogonal, the distance between the coils is Can be shortened.

  Further, as shown in FIGS. 5 (G) and 5 (H), if the magnetic flux generation directions are orthogonal to each other, it is possible to arrange the coils at the same center. . If the arrangement shown in FIGS. 5G and 5H is employed, the mounting area of the coil can be reduced.

  In addition, about each coil, you may raise the coupling | bonding degree with the coil which opposes further using the core (not shown) which consists of a magnetic body.

  Next, the operation of the setting diagnosis system 200 according to this embodiment will be described.

  The electronic device 21 normally operates independently of the setting diagnosis device 1 with power supplied from the external power source 35. More specifically, in the electronic device 21, the control unit 27, the memory 29, the main function unit 31, and the interface circuit 30 are operated by power supplied from the external power source 35 and exhibit various functions.

  The setting diagnosis device 1 is installed in the vicinity of the electronic device 21 when the electronic device 21 is regularly diagnosed, when an abnormality is diagnosed, or when a setting is changed. Since the electronic device 21 does not include an output unit or an input unit capable of displaying detailed data, the installation of the setting diagnosis device 1 adds these functions.

  The setting diagnosis apparatus 1 is arranged so that the power supply coil 2 and the transmission / reception coil 4 face the power reception coil 4 and the transmission / reception coil 24 when used.

  In the setting diagnosis device 1, when an operation signal for diagnosing the electronic device 21 is input from the input unit 10, the control unit 7 starts the setting diagnosis process illustrated in FIG. 6.

  As shown in FIG. 6, the control unit 7 drives the power feeding circuit 3 to start power feeding to the electronic device 21 via the power feeding coil 2 (step S1).

  Subsequently, the control unit 7 confirms the operation of the electronic device 21 as preprocessing for the setting diagnosis operation after the start of the power feeding operation. First, the control unit 7 initializes the number Ns of device confirmation request transmissions to 0 (step S2). Subsequently, the control unit 7 transmits a device confirmation request to the electronic device 21 via the transmission circuit 5 and the transmission / reception coil 4 (step S3).

  Subsequently, the control unit 7 adds 1 to the transmission count Ns (step S4). Subsequently, the control unit 7 determines whether or not there is a response from the electronic device 21 (step S5). When the control unit 27 of the electronic device 21 receives the device confirmation request via the transmission / reception coil 24 and the reception circuit 26, it returns a response including the power supply information state of the electronic device 21. Here, it is determined whether or not there is this response.

  When there is no response from the electronic device 21 (for example, when normal data cannot be received) (step S5; No), the control unit 7 determines whether or not the number of transmissions Ns is equal to or greater than the maximum number of times Ns_max. Determination is made (step S6). If the transmission count Ns is not equal to or greater than the maximum count Ns_max (step S6; No), the control unit 7 retransmits the device confirmation request (step S7), and returns to step S4.

  As long as there is no response yet (step S5; No) and the number of transmissions Ns is not equal to or greater than the maximum number Ns_max (step S6; No), steps S4 → S5 → S6 → S7 are repeated, and the number of transmissions Ns is counted up. .

  When the number of transmissions Ns becomes equal to or greater than the maximum number of times Ns_max (step S6; Yes), the control unit 7 determines that a communication abnormality has occurred or the electronic device 21 is not compatible with the setting diagnosis device 1, and the output is performed. An abnormal state is output to the unit 11 (step S8). Thereafter, the control unit 7 terminates abnormally when an abnormality has occurred, and terminates all setting / diagnosis processes.

  On the other hand, when there is a response from the electronic device 21 (step S5; Yes), the power supply state determination unit 8 of the control unit 7 executes a subroutine for analyzing the received response content from the electronic device 21 (step S9).

  In this subroutine, as shown in FIG. 7, the power supply state determination unit 8 extracts power supply information from the data received from the electronic device 21 (step S101). Subsequently, the power supply state determination unit 8 determines whether or not power is supplied from the external power supply 35 based on the extracted power supply information (step S102).

  When it is determined that power is supplied from the external power source 35 (step S102; Yes), the power supply state determination unit 8 sets the power supply state flag Ps_flg to 1 (step S103), and the subroutine is terminated. On the other hand, when it is determined that power is not supplied from the external power source 35 (step S102; No), the power supply state determination unit 8 sets the power supply state flag Ps_flg to 0 (step S104) and ends the subroutine.

  Returning to FIG. 6, the power supply state determination unit 8 determines whether or not the electronic device 21 is in the power supply state based on the power supply state flag Ps_flg (step S10). Here, the “power supply state” indicates either a state in which the electronic device 21 is operated by the external power source 35 or a state in which the electronic device 21 is operated by power supply from the setting diagnosis device 1.

  If it is determined that the electronic device 21 is not in the power supply state (step S10; No), the external power source 35 is not connected, so the control unit 7 maintains the power supply from the power supply circuit 3 and sets it. Diagnosis processing is executed (step S11). After the execution of the setting / diagnosis process is completed, the control unit 7 causes the power supply circuit 3 to stop supplying power from the setting diagnostic device 1 (step S12). Thereafter, the control unit 7 ends the process.

  On the other hand, if it is determined that the electronic device 21 is in the power supply state (step S10; Yes), the electronic device 21 is already supplied with power from the external power supply 35. The circuit 3 is stopped to supply power (step S13). Subsequently, in a state where the power feeding operation is stopped, the control unit 7 executes a setting / diagnosis process (step S14). Thereafter, the control unit 7 completes the process.

  As described above, in the state where the external power supply 35 is connected, the electronic device 21 is supplied with power to all the components including the main function unit 31. On the other hand, when the external power supply 35 is not connected and power is supplied from the setting diagnosis device 1, power is supplied only to the components related to the setting diagnosis of the electronic device 21.

  When the setting diagnosis device 1 is installed, the electronic device 21 returns a response to the setting diagnosis device 1 as to whether or not power is supplied from the external power source 35. The setting diagnosis device 1 stops power supply when the electronic device 21 is operated by power supply from the external power supply 35.

  The case where the electronic device 21 is not supplied with power from the external power source 35 includes the manufacturing process of the electronic device 21 and the initial setting after the electronic device 21 is installed. Examples of parameters that should be set at a minimum for the electronic device 21 to operate include, for example, parameters such as an address and protocol in the I / F circuit 30 connected to an external device, and functions of the main function unit 31 of the electronic device 21. There are selection parameters and configuration selection parameters. If these parameters are not properly set, normal operation cannot be expected even if the electronic device 21 is operated by connecting to the external power source 35. Therefore, power is supplied from the setting diagnosis device 1, and the electronic device 21 These parameters are set by operating only some of the functions.

  On the other hand, in a state in which the electronic device 21 is supplied with power from the external power supply 35, the setting diagnosis device 1 does not need to supply power to the electronic device 21, so stops the power supply operation and performs only setting diagnosis by data transmission / reception. Such an operation is performed when changing the set values of parameters such as periodic diagnosis, diagnosis at the time of occurrence of abnormality, performance correction due to secular change, and the like.

  As described above in detail, according to this embodiment, the power supplied from the external power supply 35 and converted by the power supply circuit 32 is supplied to the entire electronic device 21 while being received by the power receiving coil 22. The power converted by the circuit 23 is supplied to the transmission circuit 25, the reception circuit 26, the control unit 27, and the memory 29. As a result, the range in which the electronic device 21 operates can be limited to a necessary range in accordance with the supply state of power to the electronic device 21, thereby reducing the power consumption and cost of the electronic device 21 and the setting diagnosis device 1. In addition, it is possible to reduce their size.

  Further, according to this embodiment, it is possible to transmit and receive data between the setting diagnosis device 1 and the electronic device 21 in a non-contact manner by electromagnetic induction coupling. Thereby, since it is not necessary to incorporate the tag and the interface for connecting the tag and the control unit into the electronic device 21, it is possible to suppress an increase in power consumption and cost. In addition, since data transmission / reception by electromagnetic inductive coupling is performed at a close distance, information leakage can be prevented.

  In addition, when data is transmitted and received, it is not necessary to perform special conversion according to the communication specifications by the microprocessor, so that the processing load on the electronic device 21 can be reduced. In addition, even when power is not supplied from the external power supply 35, power can be received using the power receiving circuit 23, data can be transmitted and received, and parameters can be set.

  In addition, according to this embodiment, the setting diagnosis device 1 can function as an input / output unit, so that the electronic device 21 does not require an input / output unit. As a result, the power consumption, cost, and processing burden of the electronic device 21 can be reduced.

  As described above, according to this embodiment, a general electronic device can be used while preventing leakage of information without increasing power consumption, cost, and processing burden, and without increasing the size of the device. 21 setting or diagnosis can be easily performed.

  Further, according to this embodiment, since the electrical contact of the interface is not required, the reliability of the contact can be improved and the handling can be facilitated.

  Further, if the setting diagnosis system 200 is used, an electrical contact for data transmission / reception is not required, so that insulation between the electronic device 21 and the setting diagnosis device 1 is ensured. Thereby, the safety | security of the person who uses the setting diagnostic apparatus 1 can be ensured. In addition, since there is no mechanical defect of the interface, the reliability of data communication is improved. Moreover, since it is non-contact, handling of the setting diagnosis apparatus 1 becomes easy.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described.

  As shown in FIG. 8, in the setting diagnosis apparatus 1 according to this embodiment, a transmission / reception coil and a feeding coil are combined into one coil as a feeding coil 2, and a transmission circuit is used instead of the transmission circuit 5. 15 is different from the setting diagnosis apparatus 1 according to the first embodiment. In addition, the electronic device 21 is based on the electronic device according to the first embodiment in that the transmission / reception coil and the power reception coil are combined in the power reception coil 22 and the transmission circuit 36 is provided instead of the transmission circuit 25. Different from the device 21.

  In this embodiment, both data transmission and reception and power feeding are performed using a pair of power receiving coil 2 and power feeding coil 22. More specifically, data transmission is performed using a carrier wave used for power supply.

  FIG. 9 shows a circuit configuration for performing data transmission / reception using a carrier wave for power supply.

  As shown in FIG. 9, the power feeding circuit 3 is different from the first embodiment in that it includes a signal input unit 82. The signal input unit 82 is inserted between the DC voltage input terminal 40 and the DC / AC conversion circuit 41. The signal input unit 82 includes an input terminal 82i, a voltage amplitude changing resistor 82r, and a switching element 82s. The transmission circuit 15 is connected to the input terminal 82i.

  On the other hand, the power receiving circuit 23 is different from the first embodiment in that the power receiving circuit 23 includes a signal input unit 72. The signal input unit 72 is inserted between the smoothing capacitor 52 and the DC voltage output terminal 53. The signal input unit 72 includes an input terminal 72i, a resistor 72r, and a switching element 72s. The transmission circuit 36 is connected to the input terminal 72i.

  Next, the operation of the setting diagnosis system 200 according to this embodiment will be described.

  First, operations related to power supply in the setting diagnosis system 200 are the same as those in the first embodiment.

  Data transmission from the setting diagnosis device 1 to the electronic device 21 is performed as follows.

  The DC / AC conversion circuit 41 operates by a drive signal input to the terminals 43 </ b> P and 43 </ b> N of the drive signal input unit 43 output from the control unit 7 and supplies power to the electronic device 21. While the power is being supplied, a data signal is input from the control unit 7 to the input terminal 82i. When the switching element 82s repeats the on / off operation according to the data signal, both ends of the resistor 82r are repeatedly opened and shorted according to the on / off operation.

  As a result, the voltage output from the DC / AC conversion circuit 41 changes, and the induced voltage generated in the power receiving coil 22 of the electronic device 21 changes. By detecting and demodulating this change by the receiving circuit 26, the data signal is transmitted from the setting diagnosis device 1 to the electronic device 21. That is, in this embodiment, a data signal is superimposed on a carrier wave for supplying power, and the data signal is transmitted together with the power. That is, the data signal communication method according to this embodiment is the ASK modulation method (FIG. 4B).

  Further, data transmission from the electronic device 21 to the setting diagnosis device 1 is performed as follows.

  The DC / AC conversion circuit 41 operates by a drive signal input to the terminals 43 </ b> P and 43 </ b> N of the drive signal input unit 43 output from the control unit 7 and supplies power to the electronic device 21. While the power is being supplied, a data signal is input from the transmission circuit 36 to the input terminal 72i. When the switching element 72s repeats the on / off operation according to the transmission signal, both ends of the resistor 72r repeat open and short according to the on / off operation.

  As a result, the load current consumed by the electronic device 21 changes, and a voltage change occurs in the power supply coil 2 of the setting diagnosis device 1 according to the change. This change is detected and demodulated by the receiving circuit 6, whereby a data signal is transmitted from the electronic device 21 to the setting diagnosis device 1.

  Thus, since the setting diagnosis system 200 superimposes the data signal on the power carrier wave to the electronic device 21 of the setting diagnosis apparatus 1, the number of coils can be halved. However, since the communication speed depends on the carrier for power supply, the communication speed is lower than that of the setting diagnosis system 200 according to the first embodiment.

  The setting diagnosis process of the setting diagnosis system 200 according to this embodiment is the same as that in the first embodiment.

  In this embodiment, when the electronic device 21 is in a power supply state in step S10 (see FIG. 6) (step S10; Yes), since the power supply to the electronic device 21 is not necessary, the condition of the carrier wave It is good also as conditions different from the conditions required for electric power feeding. For example, the communication may be performed at a higher frequency than the carrier wave frequency for power feeding at a higher speed than when the power feeding is performed simultaneously.

  Further, the power consumption may be suppressed by setting the amplitude of the carrier wave lower than that during power feeding.

  As described above in detail, according to this embodiment, since the number of coils can be reduced, the electronic device 21 and the setting diagnosis device 1 can be reduced in size and cost.

  Further, since the coils are paired, it is easy to face the coils.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described.

  FIG. 10 shows a configuration of an air conditioning system 100 to which the setting diagnosis system 200 according to this embodiment is applied. As shown in FIG. 10, the air conditioning system 100 includes a setting diagnosis device 1, an outdoor unit 101, an indoor unit 102, a remote controller 21 b, a refrigerant pipe 103, a power communication line 104, a communication line 105, and a setting diagnosis unit 106.

  The power communication line 104 connects the outdoor unit 101 and the indoor unit 102. The communication line 105 connects the indoor unit 102 and the remote controller 21b.

  The setting diagnosis apparatus 1 includes the power supply coil 2 and the transmission / reception coil 4 as in the above embodiments.

  In FIG. 10, the feeding coil 2 and the transmission / reception coil 4 are combined into one and are shown as a coil 2/4. Hereinafter, it is also referred to as a coil 2/4 for simplification. Actually, the feeding coil 2 and the transmission / reception coil 4 can be shared by one coil. In this case, the setting diagnosis apparatus 1 may include only the power feeding coil 2 as in the second embodiment.

  The setting diagnosis apparatus 1 further includes an input unit 10 and an output unit 11 as in the above embodiments. The input unit 10 includes a plurality of buttons or a keyboard. The output unit 11 includes a liquid crystal display.

  The outdoor unit 101 includes a control board 21a. In this embodiment, the control board 21 a corresponds to the electronic device 21. The control board 21a includes a power reception coil 22a and a transmission / reception coil 24a. The power reception coil 22a and the transmission / reception coil 24a correspond to the power reception coil 22 and the transmission / reception coil 24 according to the above embodiments.

  The power supply coil 22a and the transmission / reception coil 24a are installed on the control board 21a or the casing of the outdoor unit 101. In FIG. 10, the feeding coil 22a and the transmission / reception coil 24a are combined into one, and are shown as coils 22a / 24a. Hereinafter, it is also referred to as a coil 22a / 24a for simplification. Actually, the power reception coil 22a and the transmission / reception coil 24a can be shared by one coil. In this case, the setting diagnosis apparatus 1 may include only the power receiving coil 2 as in the second embodiment.

  By arranging the setting diagnosis device 1 so that the power receiving coil 22a faces the power feeding coil 2, electric power is supplied from the setting diagnosis device 1 to the control board 21a. Further, by arranging the setting diagnosis device 1 so that the transmission / reception coil 24a faces the transmission / reception coil 4, data can be transmitted / received between the control board 21a and the setting diagnosis device 1, and in this state, the air conditioning system 100 initial settings and diagnosis are performed.

  In the outdoor unit 101, the casing is generally formed of a metal such as a plated steel plate. For this reason, in the electromagnetic induction method, if there is a metal between the power receiving coil 2 and the transmission / reception coil 4 and the feeding coil 22a and the transmission / reception coil 24a, electromagnetic induction coupling cannot be performed. Therefore, in this embodiment, the setting diagnosis unit 106 is provided with a door that can be opened and closed. If it does in this way, if the door is opened, electric power feeding and communication can be prevented from being hindered by a metal casing.

  Note that only the setting diagnosis unit 106 is made of a non-magnetic material such as resin, and a metal is inserted between the power supply coil 2a, the transmission / reception coil 4a, the power reception coil 4a, and the transmission / reception coil 24a. It may not be possible.

  Although the case where the setting diagnosis apparatus 1 is connected to the control board 21a will be described here, the setting diagnosis apparatus 1 may be connected to the remote controller 21b. In this case, as shown in FIG. 10, a power receiving coil 22b and a transmitting / receiving coil 24b corresponding to the power receiving coil 22 and the transmitting / receiving coil 24 are provided in the remote control 21b, and the coil 2/4 of the setting diagnosis apparatus 1 is provided to them. By making them face each other, power supply to the remote controller 21b and setting or diagnosis of the air conditioning system 100 may be performed. In this case, the remote controller 21 b corresponds to the electronic device 21.

  Next, the operation of the air conditioning system 100 to which the setting diagnosis apparatus 1 is applied will be described.

  Here, it is assumed that the air conditioning system 100 is installed as equipment of a building such as a store or a building. The outdoor unit 101 and the indoor unit 102 are already connected by the refrigerant pipe 103 and the power communication line 104, and the indoor unit 102 and the remote controller 21b are connected by the communication line 105, and the installation in the building is completed. It shall be.

(Initial setting operation)
At this stage, an initial setting operation of the air conditioning system 100 is performed. First, the initial setting operation will be described. In the initial setting operation, various parameters of the air conditioning system 100 are set.

  The main parameters set in the initial setting operation include, for example, the capacity limit value of the outdoor unit 101, the current limit value, the number of connected indoor units 102, the operation of the wind direction vane of the indoor unit 102 and the setting angle when fixed, the outdoor There are communication addresses used for communication between the unit 101, the indoor unit 102, and the remote controller 21b, and the address of the indoor unit 102 to which the remote controller 21b is connected. If these parameters are not set, the air-conditioning system 100 cannot be normally operated even when the power is turned on, so that an initial setting operation is necessary.

  Although it is possible to turn on the power of the air conditioning system 100 and start the air conditioning system 100 to perform the initial setting operation, when the air conditioning system 100 is started, power is supplied to the entire air conditioning system 100. As a result, power is also supplied to portions not related to the initial setting operation. The electric power supplied to this part becomes useless electric power and there is a possibility that an operator may be electrocuted. Therefore, in this embodiment, the setting diagnosis device 1 is used to perform an initial setting operation before turning on the power of the air conditioning system 100.

  In the initial setting operation, if necessary, the setting diagnosis unit 106 is used (for example, the door is opened), the setting diagnosis device 1 is brought close to the setting diagnosis unit 106, and the feeding coil 2 and the receiving coil 22a are opposed to each other. The transmitting / receiving coil 4 and the transmitting / receiving coil 24a are opposed to each other. Thereafter, the setting values of the various parameters described above are transmitted from the setting diagnosis apparatus 1 to the control board 21a.

  The initial setting operation of the various parameters described above from the setting diagnosis apparatus 1 to the control board 21a will be described in more detail with reference to FIG.

  When the input unit 10 is operated with the coil 2/4 of the setting diagnostic device 1 and the coil 22a / 24a of the control board 21a facing each other (for example, when the power button is pressed), the setting diagnostic device 1 is activated and the control unit 7 starts operating.

  Thereafter, AC power supplied from the external power supply 14 is converted into predetermined DC power by the power supply circuit 12 and supplied to each component of the setting diagnosis apparatus 1. The operating state of the setting diagnosis device 1 is output to the output unit 11. An operation state of the setting diagnosis device 1 is displayed on the output unit 11 (for example, a liquid crystal display).

  On the other hand, the control unit 7 executes the program stored in the memory 9 to input an instruction to the output unit 11 so as to input whether to input or change a parameter setting value or to perform a diagnosis process. Prompts you to

  In addition, the control unit 7 drives the power supply circuit 3 so as to convert the DC voltage supplied from the power supply circuit 12 into an AC voltage and supply the AC voltage to the power supply coil 2. The AC power supplied to the power feeding coil 2 is supplied to the power receiving circuit 23 via the power receiving coil 22 electromagnetically coupled to the power feeding coil 2.

  The power receiving circuit 23 converts the supplied AC power into a DC voltage and outputs it to the power supply circuit 28. The power supply circuit 28 supplies this DC power to the components necessary for the setting operation of the electronic device 21 via the power supply path 34. The components to which power is supplied are the control unit 27, the memory 29, the transmission circuit 25, and the reception circuit 26.

  No power is supplied to the I / F circuit 30 and the main function unit 31 (see FIG. 1). In the air conditioning system 100, the I / F circuit 30 corresponds to a communication interface with the indoor unit 102. The I / F circuit 30 transmits and receives data signals and also supplies power to the indoor unit 102. Furthermore, the I / F circuit 30 also supplies power to the remote controller 21b connected to the indoor unit 102. In the initial setting operation, no power is supplied because the I / F circuit 30 does not need to operate.

  In the air conditioning system 100, the function corresponding to the main function unit 31 is an air conditioning function such as cooling or heating. Constituent elements of the air conditioning system 100 driven when air conditioning is performed include a compressor, a fan motor, a solenoid valve mounted on the outdoor unit 101, and a fan motor of the indoor unit 102 connected to the end of the power communication line 104. And vanes for wind direction control. In the initial setting operation, it is not necessary to operate the main function unit 31, and therefore no power is supplied.

  After power supply to the electronic device 21 is started, the control unit 7 transmits a data signal to the electronic device 21 via the transmission circuit 5 and the transmission / reception coil 4. The control unit 7 receives a response of the electronic device 21 to the transmission via the transmission / reception coil 4 and the receiving circuit 6 and determines whether or not the electronic device 21 is capable of setting diagnosis by the setting diagnosis device 1.

  After the power supply operation from the setting diagnosis apparatus 1 is started, a signal transmitted from the setting diagnosis apparatus 1 is received by the receiving circuit 6 via the transmission / reception coil 4 and transmitted to the control unit 27. The control unit 27 returns a response signal including power supply information to the setting diagnosis device 1 via the transmission circuit 25 and the transmission / reception coil 24.

  In the initial setting operation after the air conditioning system 100 is installed, the operation is performed by the power supply from the setting diagnosis device 1 and no power is supplied from the external power supply 35. Therefore, the power supply information at this time is the external power supply 35. This is information indicating that there is no power supply from.

  In the setting diagnostic device 1, a response signal from the electronic device 21 is received by the receiving circuit 6 via the transmission / reception coil 4 and transmitted to the control unit 7. The power supply state determination unit 8 of the control unit 7 acquires the power supply information of the electronic device 21 included in the response signal, and determines the power supply state of the electronic device 21 based on the acquired power supply information. Here, since the power supply information indicates no power supply from the external power supply 35, it is determined that there is no power supply from the external power supply 35, and the setting operation is performed without stopping the power supply.

  Thereafter, the control unit 7 outputs a display for prompting parameter setting or diagnosis processing to the output unit 11. The user who sees this display operates the input unit 10 to select a setting and input a setting value of each parameter. Note that, by operating the input unit 10, the parameter setting values stored in advance in the memory 9 may be read and the parameters may be set.

  After that, when the input unit 10 is operated (for example, a setting execution button is pressed) and a setting execution command is input, the control unit 7 sends the parameter setting value together with the parameter setting instruction to the transmission circuit 5 and the transmission / reception coil. 4 to the electronic device 21.

  In the electronic device 21, the parameter setting instruction and the parameter setting value transmitted from the setting diagnosis device 1 are received by the receiving circuit 26 via the transmission / reception coil 24 and transmitted to the control unit 27. The control unit 27 stores the parameter setting value in the memory 29 in accordance with the received parameter setting instruction.

  When the transmission of the parameter setting values and the like from the setting diagnosis apparatus 1 is completed, and the reception and setting of the parameter setting values are normally completed, the control unit 27 sends a normal completion response to the transmission circuit 25 and the transmitting / receiving coil 24. To the setting diagnosis apparatus 1 via On the other hand, when an error in the received parameter setting value or a parameter setting failure is detected, the control unit 27 sends an abnormal end response to the setting diagnosis device 1 via the transmission circuit 25 and the transmission / reception coil 24. Send.

  The control unit 7 of the setting diagnostic device 1 changes the subsequent processing in accordance with a response (normal completion response or abnormal end response) from the electronic device 21. When the normal completion response is received, the control unit 7 determines that the setting is completed, outputs a message indicating the normal completion to the output unit 11, stops the power supply operation to the electronic device 21, and ends the setting process. On the other hand, when the abnormal end response is received, the control unit 7 retransmits the parameter setting value.

  When the power of the air conditioning system 100 is turned on after the setting process is completed, power supply from the external power source 35 is started to the control board 21a, and power is supplied to the entire air conditioning system 100. More specifically, AC power supplied from the external power supply 35 is converted into DC power by the power supply circuit 32 and supplied to the I / F circuit 30 and the main function unit 31 via the power supply path 33. Furthermore, since this DC power is also supplied to the power supply circuit 28, the DC power is also supplied to the control unit 27, the memory 29, the transmission circuit 25, and the reception circuit 26.

  After power supply starts, the control unit 27 executes a program stored in the memory 29. By executing this program, parameter setting values are read out, and subsequent programs are executed in accordance with the read parameter setting values.

  Such parameters include, for example, the capacity limit value of the outdoor unit 101, the current limit value, the number of connected indoor units 102, the operation of the wind vanes of the indoor unit 102, the angle at the time of fixing, and the like. Furthermore, a communication address used for communication between the outdoor unit 101, the indoor unit 102, and the remote controller 21b, an address of the indoor unit 102 to which the remote controller 21b is connected, and the like are included.

  The control unit 27 transmits the parameter setting values stored in the memory 29 to be used by the indoor unit 102 or the remote controller 21b to the indoor unit 102 or the remote controller 21b via the I / F circuit 30. .

  Although the case where the control board 21a is the electronic device 21 has been described here, the initial setting operation is performed in the same procedure when the electronic device 21 is the remote controller 21b.

(Diagnosis operation)
Next, the diagnostic operation of the air conditioning system 100 will be described. The diagnosis operation includes, for example, an initial diagnosis performed after the initial setting operation is completed, a periodic diagnosis performed periodically, and an abnormality diagnosis performed when a failure or abnormality occurs.

  The diagnosis of the air conditioning system 100 is performed based on various information provided from the air conditioning system 100. As such information, for example, the operating state of the air conditioning system 100 (compressor, fan, vane, electromagnetic valve state), communication state, refrigeration cycle state, abnormality information, refrigerant amount, failure state of each component, There is such a history.

  If the initial setting is completed, the air conditioning system 100 can be operated by power supply from the external power source 35. In the diagnosis operation, information is acquired in a state where the air conditioning function as the main function unit 31 is operated.

  In the diagnosis operation, if necessary, the setting diagnosis unit 106 is used (for example, the door is opened), the setting diagnosis apparatus 1 is brought close to the setting diagnosis unit 106, and the power feeding coil 2 and the power receiving coil 22a are opposed to each other to transmit / receive. The coil 4 and the transmission / reception coil 24a are opposed to each other. Thereafter, the setting diagnosis apparatus 1 acquires the information as described above from the control board 21a and diagnoses the air conditioning system 100.

  First, when the input unit 10 is operated in a state where the coil 2/4 of the setting diagnosis apparatus 1 and the coil 22a / 24a of the control board 21a face each other (for example, when the power button is pressed), the setting is performed. The diagnostic device 1 is activated and the control unit 7 starts operating.

  Thereafter, AC power supplied from the external power supply 14 is converted into predetermined DC power by the power supply circuit 13 and supplied to each component of the setting diagnosis apparatus 1. The operating state of the setting diagnosis device 1 is output to the output unit 11. The operation state of the setting diagnosis device 1 is displayed on, for example, a liquid crystal display of the output unit 11.

  On the other hand, the control unit 7 executes the program stored in the memory 9 to input an instruction to the output unit 11 so as to input whether to input or change a parameter setting value or to perform a diagnosis process. Prompts you to

  Further, the control unit 7 causes the power supply circuit 3 to convert the DC voltage supplied from the power supply circuit 12 into an AC voltage and supply the AC voltage to the power supply coil 2. The AC power supplied to the power feeding coil 2 is supplied to the power receiving circuit 23 via the power receiving coil 22 electromagnetically coupled to the power feeding coil 2.

  The power receiving circuit 23 converts the supplied AC power into a DC voltage and outputs it to the power supply circuit 28. The power supply circuit 28 supplies this DC power to the components necessary for the setting operation of the electronic device 21 via the power supply path 34. At this time, components to which power is supplied are the control unit 27, the memory 29, the transmission circuit 25, and the reception circuit 26.

  After power supply to the electronic device 21 is started, the control unit 7 transmits a data signal to the electronic device 21 via the transmission circuit 5 and the transmission / reception coil 4. The control unit 7 receives a response of the electronic device 21 to the transmission via the transmission / reception coil 4 and the receiving circuit 6 and determines whether or not the electronic device 21 is capable of setting diagnosis by the setting diagnosis device 1.

  After the power supply operation from the setting diagnosis apparatus 1 is started, a signal transmitted from the setting diagnosis apparatus 1 is received by the receiving circuit 6 via the transmission / reception coil 4 and transmitted to the control unit 27. The control unit 27 returns a response signal including the power supply information to the setting diagnosis apparatus 1 via the transmission circuit 21 and the transmission / reception coil 24.

  In the setting diagnosis apparatus 1, a response signal from the control board 21 a is received by the receiving circuit 6 via the transmission / reception coil 4 and transmitted to the control unit 7. The power supply state determination unit 8 of the control unit 7 acquires the power supply information of the electronic device 21 included in the response signal, and determines the power supply state of the electronic device 21 based on the acquired power supply information. Here, since the power supply information indicates that there is power supply from the external power supply, it is determined that there is power supply from the external power supply 35, and the control unit 7 stops the operation of the power supply circuit 3.

  Thereafter, the control unit 7 outputs a display for selecting the parameter setting operation or the diagnostic operation to the output unit 11. The user who sees this display operates the input unit 10 to select a diagnostic operation. Note that, by operating the input unit 10, the diagnostic parameter setting value stored in advance in the memory 9 may be read to start the diagnostic operation.

  Thereafter, when the input unit 10 is operated (for example, a diagnosis execution button is pressed) and a diagnosis execution command is input, the control unit 7 receives the set diagnosis instruction (air conditioner control instruction or information acquisition instruction), The data is transmitted to the electronic device 21 via the transmission circuit 5 and the transmission / reception coil 4.

  In the electronic device 21, the diagnostic instruction transmitted from the setting diagnostic device 1 is received by the receiving circuit 26 via the transmission / reception coil 24 a and transmitted to the control unit 27. The control unit 27 controls the main function unit 31 according to the received diagnostic instruction, acquires diagnostic information, and transmits the diagnostic information to the setting diagnostic apparatus 1. On the other hand, when an error or the like of the received data is detected, the control unit 27 transmits an abnormality occurrence response to the setting diagnosis apparatus 1 via the transmission circuit 25 and the transmission / reception coil 24.

  The control unit 7 changes the subsequent processing according to the response (diagnosis information or abnormal end response) from the electronic device 21. When receiving the diagnostic information, the control unit 7 outputs the diagnostic information to the output unit 11 and presents the information to the user. The received diagnostic information may be analyzed using a program or data stored in the memory 9 and the analysis result may be presented to the user.

  On the other hand, when receiving the abnormal termination response, the control unit 7 retransmits the diagnosis instruction.

  Data transmission / reception is repeated between the setting diagnosis device 1 and the electronic device 21 until the diagnosis process is completed. When the diagnosis process is completed (for example, when the user performs an end operation by operating the input unit 10), the control unit 7 transmits a diagnosis end notification to the control unit 27. When the control unit 27 receives the diagnosis end notification, the control unit 27 transmits the response to the setting diagnosis apparatus 1 and then shifts from the diagnosis operation to the normal operation.

  After receiving the response from the control unit 27, the control unit 7 ends the diagnosis process.

  Here, the case where the air conditioning system 100 is supplied with power from the external power supply 35 has been described. However, even when the air conditioning system 100 is not supplied with power from the external power supply 35, the air conditioning system can be diagnosed.

  During the operation of the air conditioning system 100, the control unit 27 holds a history of the operation (including abnormal operation) in the memory 29. Even when power is not supplied from the external power supply 35, the history stored in the memory 29 can be acquired from the control board 21a as a diagnosis process, and the air conditioning system 100 can be diagnosed using the acquired history. Is possible.

  The parameter setting operation when power is supplied from the external power source 35 is the same as the above-described diagnosis operation, except that the selected instruction content is not a diagnosis instruction but a setting instruction.

  In addition, even when power is supplied to the air conditioning system 100 from the external power supply 35, it is possible to change the parameter setting values that do not affect the performance and safety of the air conditioning system 100. Examples of such parameters include the operation of the louver of the indoor unit 102 and the angle. The parameter setting operation when power is supplied from the external power supply 35 is the same as the above-described diagnosis operation, except that the selected instruction content is not a diagnosis instruction but a setting instruction.

  As described above, by using this setting diagnosis device 1, it is possible to initially set parameters of the air conditioning system 100 after the air conditioning system 100 is installed. Further, if this setting diagnosis device 1 is used, periodic diagnosis is performed to diagnose the deterioration state of component parts due to aging deterioration or the like, or the leakage state of the refrigerant, or the parameter setting value is updated to change the operation program. can do. Moreover, if this setting diagnosis apparatus 1 is used, it can diagnose irregularly and can investigate the cause when an abnormality or a failure occurs in the air conditioning system 100 and take countermeasures.

  Moreover, if this setting diagnosis apparatus 1 is used, the same parameter setting values can be set for the plurality of air conditioning systems 100.

  Furthermore, if this setting diagnosis apparatus 1 is used, a parameter setting value in an air conditioning system 100 can be acquired from the air conditioning system 100 and the setting value can be set in another air conditioning system 100. That is, the setting diagnosis apparatus 1 is also suitable for copying parameter setting values to other air conditioning systems.

  As described above in detail, according to this embodiment, by applying the setting diagnosis device 1 to the air conditioning system 100, the initial setting at the introduction of the air conditioning system 100, the periodic diagnosis, the occurrence of an abnormality, It becomes possible to simplify the diagnosis work at the time of failure.

  In addition, according to this embodiment, it is not necessary to wire-connect the setting diagnosis apparatus 1 after opening the housing of the outdoor unit 101 and exposing the internal circuit, so that the operator touches the high voltage portion. The risk of electric shock and the like can be reduced, and the work is simplified, so that the burden on the operator can be reduced.

  The remote controller 21b has an input button for operating the air conditioning system 100, a display output, and the like. However, if a complicated system diagnosis function is installed in such a remote controller 21b or the indoor unit 102, the cost becomes low. Will increase. According to this embodiment, since the system diagnosis function is installed in the setting diagnosis apparatus 1, an increase in the cost of the air conditioning system 100 can be suppressed.

Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described.

  FIG. 11 shows a configuration of a sensor device 21c to which the electronic device diagnostic apparatus according to this embodiment is applied.

  As shown in FIG. 11, the sensor device 21 c is installed between the electric device 111 and the external power source 110. The sensor device 21c is a power measurement sensor that measures power consumption, power consumption, voltage, current, power factor, and the like of the electrical device 111.

  The sensor device 21c does not have a function of displaying a measurement value. The sensor device 21c transmits the measurement value to another device, for example, the measurement data aggregation device 112 via the transmission path 113 via the external interface. The transmission path 113 may be wired or wireless.

  The sensor device 21c includes a power reception coil 22c and a transmission / reception coil 24c. The sensor device 21c includes a plurality of light emitting diodes 114 as simple display means.

  As described in the above embodiment, in the sensor device 21c, when the coil is shared, only the power receiving coil 22c may be provided. In this case, as the setting diagnosis apparatus 1, the apparatus according to the second embodiment is used.

  By arranging the setting diagnosis apparatus 1 so that the coils 22c / 24c face the coil 2/4, the sensor apparatus 21c and the setting diagnosis apparatus 1 are connected. The coils 2/4 and the coils 22c / 24c are not installed barely, but are arranged inside the casings of the setting diagnosis device 1 and the sensor device 21c, which are made of a non-magnetic material, taking advantage of the characteristics of electromagnetic induction. The

  Next, the operation of the sensor device 21c to which the setting diagnosis device 1 is applied will be described.

  The initial setting operation when the sensor device 21c is not supplied with power from the external power supply 110 and the diagnosis operation when the external power supply 110 is supplied with power to the sensor device 21c are described in the third embodiment. This is the same as the operation in the air conditioning system 100.

  In this embodiment, parameters transmitted / received at the time of initial setting and diagnostic information transmitted / received at the time of diagnosis are different from those of the third embodiment.

  Such parameters include an address required when a network is formed when connecting to another device such as the aggregation device 112, identification information of the sensor device 21c, and the like. In addition, the measurement range (current measurement range) of the measurement target of the sensor device 21c, power supply specifications (single-phase or three-phase, 100V or 200V, etc.), characteristics of the current sensor such as a current transformer such as a current transformer Correction data (offset, line formation, gain, etc.) are parameters set in the initial setting operation. The main functional unit 31 in the sensor device 21c is a so-called power measurement circuit.

  A breaker (not shown) is normally installed between the external power supply 110 and the sensor device 21c. Since power is required at the time of initial setting of the sensor device 21c, when power is supplied from the external power source 110 to the sensor device 21c, the electrical device 111 connected to the power source is also energized. For this reason, in the sensor device 21c, it is necessary to perform initial setting before power is supplied from the external power supply 110.

  If the setting diagnostic device 1 is used, the sensor device 21c can be initialized while power is supplied from the setting diagnostic device 1. As a result, the initial setting of the sensor device 21c can be performed without supplying power to the electrical device 111. In addition, since the initial setting of the sensor device 21c can be performed without supplying power from the external power supply 110 to the worker, an electric shock can be prevented and work safety can be improved.

  The diagnostic information transmitted and received at the time of diagnosis includes, for example, the operation state and operation history of the sensor device 21c, detection accuracy (gain, offset), and the like. The setting diagnosis device 1 acquires these pieces of information without contact, and diagnoses the sensor device 21c based on the acquired information. As the contents of diagnosis, periodic diagnosis includes diagnosis of deterioration of component parts due to deterioration over time. Non-periodic diagnosis includes investigation of the cause when an abnormality or failure occurs in the sensor device 21c. A countermeasure can be extracted based on the investigated cause.

  The communication operation between the sensor device 21c as the electronic device 21 and the setting diagnosis device 1 is the same as the communication operation described in the first embodiment.

  The setting diagnosis device 1 acquires information such as an operation state and an operation history as diagnosis information from the sensor device 21c, and diagnoses the sensor device 21c based on the acquired diagnosis information.

  As described above, if this setting diagnosis device 1 is used, initial setting of parameters of the air conditioning system 100 after installation becomes possible. Further, if this setting diagnosis device 1 is used, periodic diagnosis is performed to diagnose the deterioration state of component parts due to aging deterioration or the like, or the leakage state of the refrigerant, or the parameter setting value is updated to change the operation program. can do. Further, if this setting diagnosis device 1 is used, it is possible to make a diagnosis non-periodically and to investigate the cause and take countermeasures when an abnormality or failure occurs in the air conditioning system 100.

Embodiment 5 FIG.
Next, a fifth embodiment of the present invention will be described.

  Some measuring instruments such as the sensor device 21c require periodic calibration. The setting diagnosis apparatus 1 can also be applied to the calibration.

  FIG. 12 shows the setting diagnosis device 1 for calibration of the sensor device 21c. As shown in FIG. 12, the setting diagnosis apparatus 1 includes a reference function unit 125. The reference function unit 125 has the same function as the function unit of the sensor device 21c, here, power consumption, power consumption, and the like, and further has measurement accuracy and measurement capability that can be used as a reference.

  The setting diagnosis device 1 is provided with a notch structure 120 for mounting the sensor device 21c. When a measuring instrument such as the sensor device 21c is mounted on the notch structure 120, the power supply coil 2 of the setting diagnosis device 1 and the power reception coil 22c of the sensor device 21c are opposed to each other.

  By connecting the setting diagnosis device 1 and the sensor device 21c, the power that satisfies the same condition is measured by the sensor device 21c and the setting diagnosis device 1 (reference function unit 125). The measured value of the sensor device 21c is transmitted to the setting diagnosis device 1 via the power feeding coil 2 and the power receiving coil 22c, and is compared with the measured value measured by the reference function unit 125.

  If calibration is possible based on the comparison result, the setting diagnosis device 1 transmits a parameter correction value to the sensor device 21c to correct the parameter set in the sensor device 21c. Thereby, calibration of the sensor device 21c is performed.

  Prior to the calibration, when the diagnostic operation is performed by the setting diagnosis device 1 and it is determined that the calibration is impossible due to aging or the like, the sensor device 21c is replaced by outputting the result to the operator. It is also possible to prompt.

  In the fourth and fifth embodiments, the sensor device 21c is a power measurement sensor that measures power consumption, power consumption, voltage, current, and power factor. However, the sensor device 21c may be a sensor that measures other physical quantities. As the sensor device, any sensor such as a temperature sensor, a humidity sensor, an illuminance sensor, an infrared sensor, a voice sensor, a vibration sensor, an acceleration sensor, and a weight sensor may be used. Further, in the manufacturing process of these sensor devices 21c, the setting diagnosis device 1 may be used for writing serial numbers and address settings.

  As described above in detail, according to this embodiment, it is possible to simplify the periodic calibration work of the sensor device 21c. Since it is not necessary to open the housing of the sensor device 21c and expose the internal circuit and connect the setting diagnosis device 1 with an electrical contact, it is possible to reduce the danger to the operator such as touching the high voltage part. In addition, the work can be simplified.

  In each of the above embodiments, the memory 9 is illustrated as a separate configuration from the control unit 7, but these may be packaged as a microprocessor or the like. The memory 9 is preferably non-volatile so that recorded information remains when the power of the setting diagnosis apparatus 1 is turned off, but may be a volatile memory.

  In each of the embodiments described above, the memory 29 is illustrated as a separate configuration from the control unit 27, but these may be packaged as a microprocessor or the like. The memory 29 is preferably non-volatile so that recorded information remains when the power of the electronic device 21 is turned off, but may be a volatile memory.

  In each of the above embodiments, the external power source 35 is an AC power source. However, the electronic device 21 may be supplied with DC power. When direct-current power is supplied, the power supply circuit 32 may perform DC / DC conversion to convert it into a required predetermined direct-current voltage.

  The present invention can be applied to an electronic device that needs to set parameters in a state where power is not supplied, an electronic device that requires insulation at the time of setting diagnosis, a building system such as an air conditioning system and a lighting system.
