The following describes one embodiment of the present invention with reference to FIGS. 1 to 6 and FIG.

(Configuration of status output system 100 of the present embodiment)
First, a schematic configuration of the state output system 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of a schematic configuration of the state output system 100. In the present embodiment, the case where the state output system 100 is applied to an air conditioner will be described as an example. However, the present invention is not limited to this. It can be applied to electrical appliances incorporating various parts.

  As shown in FIG. 2, the state output system 100 includes the state output device 1 and an operation member (motor) for operating each part of the air conditioner. And the determination result is presented to the user.

  For example, as an operation member of an air conditioner, for example, a cleaning motor 31a that operates a member that cleans the air blowing mechanism, a wind direction left and right motor 31b that operates a member that adjusts the air direction of the air blowing mechanism, a wind improving lower motor 31c, and an air blowing mechanism A fan motor 31g for operating the fan included in the air conditioner and a temperature and humidity sensor 31z for measuring the temperature and humidity of the outside air of the air conditioner are provided.

  Also, wireless detectors (signal transmission devices) 32a, 32b, 32c, and 32g are attached to the cleaning motor 31a, the wind direction left and right motor 31b, the wind improving lower motor 31c, and the fan motor 31g (or in the vicinity of these operating members), respectively. It has been. The configuration of this wireless detector will be described later with reference to FIG.

  The state output device 1 includes motor drivers 131a, 131b, 131c, and 131g for controlling the cleaning motor 31a, the wind direction left and right motor 31b, the wind improving motor 31c, and the fan motor 31g, respectively. Further, the state output device 1 includes photocouplers 101x and 101y as switching elements. The photocoupler 101x is connected to the motor driver 131g, and the photocoupler 101y is connected to the outdoor unit.

  The state output device 1 includes a wireless transmission / reception unit 2, an operation unit 4, a main control unit 5, a storage unit 6, and a display unit 7. These members will be described later with reference to FIG.

  In this embodiment, the motor drivers 131a, 131b, 131c, and 131g, the photocouplers 101x and 101y, the operation unit 4, and the display unit 7 are configured to be included in the state output device 1, but these are the state output devices. 1 may be provided outside. That is, the status output device 1 only needs to include at least the wireless transmission / reception unit 2, the main control unit 5, and the storage unit 6.

  Further, in the present embodiment, the configuration in which the state output system 100 is provided with a plurality of motors 31 is shown. However, any configuration that includes at least one operation member may be used. Good.

(Configuration of status output device 1 of this embodiment)
Next, a schematic configuration of the state output device 1 of the present embodiment will be described with reference to FIG. FIG. 1 is a functional block diagram illustrating an example of a schematic configuration of the state output device 1.

  In order to simplify the following description of the present embodiment, the temperature / humidity sensor 31z, the wireless detector 32z, the motor drivers 131 (131a to 131g), and the photocouplers 101 (101x, 101y) are omitted in FIG. doing. In addition, the motor 31 (31a to 31g) is simply referred to as a motor without distinguishing motor types such as a cleaning motor, a wind direction right / left motor, a wind improving motor, and a fan motor.

  As described above, the wireless detectors 32a to 32g are attached to the motors 31a to 31g or the vicinity thereof. Moreover, the radio | wireless detectors 32a-32g are each provided with the transmission / reception parts 33a-33g. Thereby, the status output device 1 can transmit and receive signals via the wireless communication medium with the wireless detectors 32a to 32g.

  Although there are a plurality of the wireless detectors 32a to 32g and the transmission / reception units 33a to 33g, when there is no need to distinguish and explain each, the wireless detection unit 32 and the transmission / reception unit 33 are simply the same as the motor 31. Collectively. Further, just as the motors 31a to 31g may be singular, the wireless detectors 32a to 32g may also be singular.

(Configuration of status output device 1)
The state output device 1 determines whether each of the motors 31a to 31g is normal (whether or not it has failed) and presents the determination result to the user. A control unit 5, a storage unit 6, and a display unit 7 are provided.

(Configuration of wireless transceiver 2)
The wireless transmission / reception unit 2 transmits / receives signals to / from the wireless detectors 32a to 32g via a wireless communication medium, and includes a radio wave transmission unit 21, a radio wave reception unit 22, and a reception availability determination unit (detection availability determination unit) 23. It has.

  The radio wave transmission unit 21 transmits radio waves to the radio detectors 32a to 32g in accordance with a transmission command from the reading command unit 51. As a result, the wireless detector 32 is energized, and a signal can be transmitted to the state output device 1.

  The radio wave receiving unit 22 receives the identification signals from the radio detectors 32 a to 32 g, and gives the reception result information as a result to the reception possibility determination unit 23.

  The reception availability determination unit 23 compares the reception result information given from the radio wave reception unit 22 with a list of different identification information of the wireless detectors 32a to 32g stored in the storage unit 6, thereby performing wireless detection. It is determined whether or not the intensity of the signal transmitted from each of the machines 32a to 32g has decreased below a predetermined value. The reception propriety determination unit 23 transmits to the failure determination unit 52 a detection determination result indicating a result of determining which of the wireless detectors 32a to 32g has a signal intensity transmitted to be lower than a predetermined value.

  Further, the wireless transmission / reception unit 2 receives a transmission function release command from the transmission function stop unit 53. In the wireless transmission / reception unit 2, the radio wave transmission unit 21 stops the transmission of the radio wave to the wireless detector 32 specified in the transmission function release command from the transmission function stop unit 53.

  For example, if the wireless detector 32 is an RFID (Radio Frequency Identification) (passive contactless authentication tag), the wireless transceiver 2 can be an RFID reader. In addition, when the wireless detector 32 is not configured to transmit a signal to the state output device 1 by being generated by the state output device 1, for example, in a configuration capable of transmitting a signal at all times, the wireless transmission / reception unit 2 transmits radio waves. The transmission unit 21 is not necessarily provided. That is, the wireless transmission / reception unit 2 is not limited to the RFID reader as long as it can read at least a signal from the wireless detector 32.

(Configuration of operation unit 4)
The operation unit 4 is for inputting various operation commands by the user including a reading instruction to the reading command unit 51. Examples of the operation unit 4 include operation buttons and their interfaces.

(Configuration of main controller 5)
The main control unit 5 controls each unit of the state output device 1 such as the wireless transmission / reception unit 2, the display unit 7, the motor drivers 131a, 131b, and 131c, and the photocouplers 101x and 101y by executing a control program. Is. The main control unit 5 reads the control program stored in the storage unit 6 (see FIG. 1) into a temporary storage unit (not shown) configured by, for example, a RAM (Random Access Memory), and executes it. Perform various processes.

  Further, the main control unit 5 determines whether or not each motor 31 has failed, and outputs the determination result to the display unit 7, and mainly includes a read command unit 51, a failure determination unit 52, and a transmission function. A stop unit 53 and a determination result output unit 54 are provided.

  The read command unit 51 gives a transmission command to the radio wave transmission unit 21 so as to transmit a radio wave to the wireless detector 32 in response to a read instruction from the user input from the operation unit 4.

  The failure determination unit 52 receives the reception result information from the reception availability determination unit 23, and determines whether or not there is a failure in the motors 31a to 31g based on the detection determination result.

  That is, the failure determination unit 52 breaks down the motors 31a to 31g corresponding to the wireless detectors 32a to 32g, which are determined in the detection determination result that the intensity of the transmitted signal has not decreased below the predetermined value. Judge that it is not. On the other hand, in the detection determination result, it is determined that the motors 31a to 31g corresponding to the wireless detectors 32a to 32g determined that the intensity of the transmitted signal is reduced to a predetermined value or less are broken.

  For example, in the detection determination result, it is determined that the intensity of the signal transmitted from the wireless detectors 32a and 32g has not decreased below a predetermined value, and the intensity of the signal transmitted from the wireless detector 32b is equal to or lower than the predetermined value. If it is determined that the motors 31a and 31g respectively correspond to the wireless detectors 32a and 32g, the failure determination unit 52 determines that the motors 31a and 31g have not failed. On the other hand, the failure determination unit 52 determines that the motor 31b corresponding to each of the wireless detectors 32b has failed.

  The failure determination unit 52 transmits a failure determination result indicating the result of determining whether or not the motors 31 a to 31 g have failed to the transmission function stop unit 53 and the determination result output unit 54.

  The transmission function stop unit 53 receives the failure determination result from the failure determination unit 52, and transmits a radio wave to the wireless detector 32 (for example, the wireless detector 32b) corresponding to the motor 31 (for example, the motor 31b) determined to be the failure. A transmission function release command, which is a release (stop) command, is transmitted to the wireless transmission / reception unit 2.

  The determination result output unit 54 plays a role of transmitting the failure determination result received from the failure determination unit 52 to the display unit 7 and outputting (displaying) the failure determination result as an image on the display unit 7.

  Although the failure determination result is output as an image here, the method of outputting the failure determination result is not limited to this. For example, the determination result output unit 54 may transmit a failure determination result to a speaker (not shown) and output the failure determination result as sound from the speaker.

  For example, in the case of the above example, the determination result output unit 54 determines an image indicating that the operation state of the motors 31a and 31g is “normal” and the operation state of the motor 31b is “abnormal”. As a result, it is output to the display unit 7. As a result, the user can easily identify the failed motor 31.

(Configuration of storage unit 6)
The storage unit 6 stores (1) a control program for each unit, (2) an OS program, (3) an application program, and (4) various data to be read when these programs are executed. Is.

(Configuration of display unit 7)
The display unit 7 is a display device that displays various image information including the failure determination result transmitted from the determination result output unit 54. The display unit 7 is, for example, a liquid crystal display. The display unit 7 may be a separate display device that is communicably connected to the state output device 1.

(Configuration of wireless detector 32)
Next, the detailed structure of the radio | wireless detector 32 is demonstrated based on (a) and (b) of FIG. 3A is a plan view of the wireless detector 32, and FIG. 3B is a cross-sectional view showing a cross section AA of the wireless detector 32 shown in FIG. 3A. is there.

  As illustrated in FIG. 3A, the wireless detector 32 includes a transmission / reception unit 33, and the transmission / reception unit 33 includes an IC unit 34 and an antenna 35. In addition, the transmission / reception part 33 is provided on the board | substrate 36, as FIG.3 (b) shows.

  The IC unit 34 records identification information (for example, an individual identification number) of the wireless detector 32. The identification information of the plurality of wireless detectors 32a to 32g is unique and different from each other. The IC unit 34 receives power from the antenna 35 and transmits identification information to the antenna 35. The antenna 35 receives a radio wave from the radio wave transmission unit 21 of the state output device 1, operates the IC unit 34, and transmits identification information transmitted from the IC unit 34 to the radio wave reception unit 22.

  As shown in FIG. 3B, the wireless detector 32 is provided with a substrate 36, an antenna insulating resin portion 37, and a heat detection resin layer 38. The wireless detector 32 is bonded to the motor 31.

(Failure detection method by wireless detector 32)
Next, a method for detecting a failure of the motor 31 by the wireless detector 32 will be described with reference to FIGS.

  As shown in FIG. 4, the wireless detector 32 is arranged such that the heat detection resin layer 38 is positioned closer to the motor 31 than the substrate 36 by the adhesive layer 39 on the motor 31 that generates heat when it fails. It is attached. The heat detection resin layer 38 is a resin having a linear expansion coefficient larger than that of the substrate 36, and expands only when the temperature reaches a first threshold value as a predetermined value. Since the heat detection resin layer 38 has a larger linear expansion coefficient than the substrate 36, the change in length due to a temperature rise is larger in the heat detection resin layer 38 than in the substrate 36.

  Consider a case where the motor 31 is not out of order, that is, the temperature of at least one of the motor 31 (detection target) and the surrounding environment is lower than the first threshold.

  The wireless detector 32 receives the radio wave from the radio wave transmission unit 21 through the antenna 35 and generates electricity to operate the IC unit 34. The IC unit 34 transmits the identification information of the wireless detector 32 to the antenna 35, and the antenna 35 transmits the received identification information to the radio wave reception unit 22 of the state output device 1.

  The radio wave receiver 22 receives the identification information of the wireless detector 32 transmitted from the wireless detector 32.

  On the other hand, consider a case where the motor 31 is out of order, that is, the temperature of at least one of the motor 31 and the surrounding environment is equal to or higher than the first threshold value.

  As shown in FIG. 5, in the wireless detector 32, when the temperature of at least one of the motor 31 and the surrounding environment rises, the heat detection resin layer 38 made of a resin having a larger linear expansion coefficient than the substrate 36 expands, The substrate 36 warps in the direction of the surface where the heat detection resin layer 38 is not provided. In the antenna 35 provided in the wireless detector 32, the portion 35a connected to the IC unit 34 is disconnected due to the warpage of the substrate 36 when the temperature reaches a predetermined temperature. In FIG. 5, a portion of the antenna 35 disposed on the substrate 36 is indicated as 35b.

  In this case, since the wireless detector 32 cannot transmit the identification information, the radio wave receiving unit 22 may receive the identification information of the wireless detector 32 (detect a signal from the wireless detector 32). Can not.

  As described above, when the motor 31 fails and the temperature of at least one of the motor 31 and the surrounding environment exceeds the first threshold value, the wireless detector 32 transmits its own identification information to the radio wave receiver 22. Can not be. Accordingly, the reception determination unit 23 determines whether or not the identification information is received from the wireless detector 32, and the failure determination unit 52 determines whether or not the motor 31 has failed using the detection determination result indicating the determination result. Determined.

  Note that, since the IC unit 34 and the antenna 35 are physically disconnected, the temperature of at least one of the motor 31 and the surrounding environment decreases and does not reconnect even after the temperature falls below the first threshold. That is, the loss (decrease) in the transmission function of the wireless detector 32 due to the disconnection that occurs between the IC unit 34 and the antenna 35 is irreversible.

  Further, here, the transmission function in the wireless detector 32 is lost due to the disconnection (that is, physical change) generated between the IC unit 34 and the antenna 35 due to the failure of the motor 31. However, the transmission function in the wireless detectors 32a to 32g does not necessarily need to be lost due to a physical change caused by the failure of the motors 31a to 31g. For example, the transmission function in the radio detectors 32a to 32g is deteriorated due to a physical change caused by the failure of the motors 31a to 31g, and the radio wave receiving unit 22 determines that the signal intensity has decreased to a predetermined value or less. The configuration may be such that high-intensity radio waves are transmitted.

  That is, the presence / absence of a failure of the motors 31a to 31g and the intensity of the signals transmitted from the radio detectors 32a to 32g corresponding to the motors 31a to 31g, which are received by the radio wave receiver 22, correspond as described above. It only has to be.

  The determination of the strength of the radio waves transmitted from the radio detectors 32a to 32g in the radio wave receiving unit 22 may be performed by a known technique. For example, a radio wave receiving circuit using a detection diode can be used.

  In the present embodiment, the example using the heat detection resin layer 38 that expands at a temperature equal to or higher than the first threshold is described, but the present invention is not limited to this. When the temperature of at least one of the motor 31 and the surrounding environment becomes lower than the first threshold using a member that causes a physical change such as contraction at a temperature equal to or lower than the first threshold, A configuration in which the transmission function is lowered may also be used.

  Further, if the material of the heat detection resin layer 38 is a resin having a humidity expansion coefficient larger than that of the substrate 36, the humidity can be detected. Thereby, for example, it is possible to detect the presence or absence of a failure of the operating member that fails at a first threshold value or higher as the predetermined humidity.

(Flow of failure detection processing in status output system 100)
Next, an example of a flow of processing for detecting whether or not the motor 31 (31a to 31g) has failed in the state output system 100 will be described.

  FIG. 6 is a flowchart illustrating an example of a failure detection process flow in the state output system 100.

  The user gives the operation unit 4 an input (reading instruction to the reading command unit 51) for causing the status output device 1 to determine whether or not the motor 31 (31a to 31g) has failed. The read command unit 51 gives a transmission command to the radio wave transmission unit 21 so as to transmit radio waves to the wireless detector 32 (32a to 32g) in accordance with an input from the user in the operation unit 4.

  The radio wave transmission unit 21 transmits a radio wave to the wireless detector 32 (32a to 32g) in accordance with the transmission command given from the reading command unit 51 (step S1).

  The wireless detector 32 (32a to 32g) receives the radio wave from the radio wave transmission unit 21 by the antenna 35 (step S2), and the antenna 35 generates power by the radio wave received from the radio wave transmission unit 21, and the IC unit 34 Is operated (step S3).

  The wireless detectors 32 (32a to 32g) are attached to the motors 31 (31a to 31g), respectively. In the wireless detector 32 (32a to 32g), whether or not the temperature of the motor 31 (31a to 31g) is within a predetermined range depending on whether or not the disconnection occurs between the antenna 35 and the IC unit 34, That is, it is determined whether or not the temperature of the motor 31 (31a to 31g) is less than the first threshold value (step S4).

  When the temperature of motor 31 (31a to 31g) is within a predetermined range, that is, lower than the first threshold (YES in step S4), no disconnection occurs between antenna 35 and IC unit 34. In that case, in the wireless detector 32 (32a to 32g), the IC unit 34 transmits the identification information of the wireless detector 32 to the antenna 35, and the antenna 35 transmits the received identification information to the radio wave receiving unit 22. (Step S5). Then, the radio wave receiver 22 receives the identification information of the wireless detector 32 from the wireless detector 32 (step S7).

  On the other hand, when the temperature of motor 31 (31a to 31g) is not within the predetermined range, that is, is equal to or higher than the first threshold (NO in step S4), disconnection occurs between antenna 35 and IC unit 34. In this case, the wireless detector 32 (32a to 32g) does not transmit its own identification information to the radio wave receiver 22 (step S6). That is, in this case, the radio wave receiver 22 does not receive the identification information of the wireless detector 32 (32a to 32g). Further, the intensity of the signal transmitted from the wireless detector 32 (32a to 32g) received by the radio wave receiving unit 22 is reduced to a predetermined value or less.

  The reception availability determination unit 23 determines whether or not the intensity of the signal transmitted from each of the wireless detectors 32 (32a to 32g) received by the radio wave reception unit 22 has decreased to a predetermined value or less. (Step S8) (Detectability determination step). The reception possibility determination unit 23 transmits a detection determination result indicating a result of determining whether or not the strength of the signal transmitted from the wireless detector 32 is reduced to a predetermined value or less to the failure determination unit 52.

  The failure determination unit 52 receives the detection determination result from the reception availability determination unit 23, and determines whether or not the motor 31 (31a to 31g) has a failure based on the detection determination result (step S9) (failure determination step). The failure determination unit 52 transmits a failure determination result indicating a result of determining whether or not the motor 31 (31a to 31g) has failed to the transmission function stop unit 53 and the determination result output unit 54.

  The determination result output unit 54 transmits the failure determination result received from the failure determination unit 52 to the display unit 7, and outputs (displays) the failure determination result as an image on the display unit 7 (step S10) (determination result) Output process).

  The transmission function stop unit 53 receives the failure determination result from the failure determination unit 52, and transmits the radio wave to the wireless detector 32 (32a to 32g) corresponding to the motor 31 (31a to 31g) determined to be the failure. A transmission function cancellation command, which is a cancellation command, is transmitted to the wireless transmission / reception unit 2.

(Effect of status output device 1)
In the state output device 1, the failure determination unit 52 determines whether or not the strength of the signal transmitted from the radio wave reception unit 22 has decreased to a predetermined value or less by the reception determination unit 23. It is determined whether or not the motor 31 (31a to 31g) corresponding to the wireless detector 32 (32a to 32g) has a failure. Then, the failure determination result by the failure determination unit 52 is presented to the user via the display unit 7.

  With such a configuration, the state output device 1 can easily and reliably determine whether or not the operating member has failed. Therefore, the user can easily and reliably identify the failed operating member.

  In the present embodiment, since the state output device 1 determines whether or not there is a failure for each of the plurality of motors 31a to 31g, it can reliably determine which motor 31a to 31g has failed. . In particular, even when a plurality of the same parts exist in the status output system 100, it is possible to easily identify the part in which an abnormality has occurred.

  Moreover, in the status output system 100, since communication between the wireless transmission / reception unit 2 and the wireless detectors 32a to 32g is performed by wireless communication, the complexity of the wiring is suppressed compared to the case of wired communication. can do.

  Further, in the state output system 100, the wireless detectors 32a to 32g can be realized by RFID (passive non-contact authentication tag), and therefore only when failure detection is necessary (that is, from the state output device 1) Only when is transmitted), the failure of the motor 31 can be detected. Therefore, power consumption can be reduced compared with the case where an active type (always driven type) detection sensor is used as a failure detection sensor (failure sensor) for an operation member.

[Modification]
In the first embodiment, the wireless detector 32 may have a plurality of structures including a transmission / reception unit (transmission unit) 33 that can transmit the identification number of the wireless detector 32 itself, that is, an IC unit 34 and an antenna 35. Here, for example, a case where a wireless detector 32 having two transmission / reception units 33 is attached to the motor 31 is considered.

  In this configuration, it is possible to prevent the transmission function of at least one transmission / reception unit 33 from being deteriorated.

  When the motor 31 is not broken down, that is, when the temperature of the motor 31 is lower than the first threshold, the wireless transmission / reception unit 2 receives the identification information (in the case of the individual identification number from the transmission / reception unit 33) of the wireless detector 32. The same number).

  On the other hand, when the motor 31 is out of order, that is, when the temperature of the motor 31 is equal to or higher than the first threshold value, the wireless detector 32 warps on the one transmission / reception unit 33 side, and the antenna 35 included in the one transmission / reception unit 33 is disconnected. To do. On the other hand, the wireless detector 32 is not warped on the other transmitting / receiving unit 33 side, and the antenna 35 provided in the other transmitting / receiving unit 33 is not disconnected. In addition, since the connection in the antenna 35 is physically disconnected, the temperature of the motor 31 is reduced and the connection is not reconnected even after the temperature falls below the first threshold.

  In this state, when a radio wave is transmitted from the radio wave transmission unit 21 to the radio detector 32, identification information of the radio detector 32 is transmitted to the radio wave reception unit 22 from the transmission / reception unit 33 where the antenna 35 is not disconnected. . On the other hand, the identification information of the wireless detector 32 is not transmitted to the radio wave receiver 22 from the transmitter / receiver 33 where the antenna 35 is disconnected.

  As described above, when the motor 31 corresponding to the wireless detector 32 has not failed, signals are transmitted from all the transmission / reception units 33. On the other hand, when the motor 31 has failed, However, the transmission functions of some of the transmission / reception units 33 are deteriorated, while the transmission functions of some of the transmission / reception units 33 are not deteriorated.

  Therefore, in the state output device 1, the failure determination unit 52 determines that the motor 31 has not failed when detecting a signal having a strength higher than a predetermined value from all of the transmission / reception units 33. When a signal having an intensity equal to or less than a predetermined value is detected from the transmission / reception unit 33, it is determined that the motor 31 has failed.

  In other words, when all of the signals transmitted from the plurality of transmission / reception units 33 cannot be detected (when all the strengths of the signals are less than or equal to a predetermined value), the failure determination unit 52 It is determined that a communication failure (communication error) has occurred without determining whether there is a failure. For example, in this case, the display unit 7 displays that a communication failure has occurred, thereby notifying the user of the occurrence of the communication failure.

  Thereby, the user can recognize the presence or absence of a failure of the motor 31 after confirming that there is no problem in the connection between the wireless detector 32 and the wireless transmission / reception unit 2. Therefore, in addition to the presence / absence of a failure of the motor 31, it is possible to determine the presence / absence of a communication error (reading error) in the wireless transmission / reception unit 2, and it is possible to more accurately determine the state of the motor 31 that is the detection target. It becomes.

  In addition, since there is a shield between the wireless detector 32 and the wireless transmission / reception unit 2, the wireless transmission / reception unit 2 cannot detect a signal having a strength higher than a predetermined value transmitted from the wireless detector 32. This prevents erroneous determination of failure that may occur in the case of the wireless detector 32 having only one transmission / reception unit 33, such as determining that the motor 31 corresponding to the wireless detector 32 has failed. be able to.

  Note that the transmission from the wireless transmission / reception unit 2 to the wireless detector 32 having at least one transmission / reception unit 33 with a reduced transmission function is stopped by a transmission function release command issued from the transmission function stop unit 53.

  In addition, transmission / reception unit identification information for identifying each transmission / reception unit 33a to 33g is recorded in each of the plurality of transmission / reception units 33a to 33g, and each transmission / reception unit 33a to 33g You may transmit to the status output apparatus 1 with the identification information of the radio | wireless detectors 32a-32g. In this case, the transmission / reception unit identification information is stored in the storage unit 6 of the state output device 1 in association with the identification information of the wireless detectors 32a to 32g. The reception availability determination unit 23 refers to the identification information to determine whether signals from all the transmission / reception units 33a to 33g are received.

[Comparative example]
Next, a schematic configuration of a state output system 1000 that is a comparative example of the state output system 100 according to the present embodiment will be described with reference to FIG. FIG. 10 is a diagram illustrating an example of a schematic configuration of the status output system 1000. Similarly to the state output system 100, the state output system 1000 will be described by exemplifying a case where it is applied to an air conditioner.

  As shown in FIG. 10, the status output system 1000 includes a status output device 1001 and an operation member (motor) for operating each part of the air conditioner, and determines whether or not the operation member is normal. The determination result is presented to the user.

  Similar to the state output system 100, the operation members include, for example, a cleaning motor 1031a, a wind direction left / right motor 1031b, a wind improving motor 1031c, a fan motor 1031g, and a temperature / humidity sensor 1031z.

  In addition, the cleaning motor 1031a, the wind direction left / right motor 1031b, the wind improvement lower motor 1031c, the fan motor 1031g, and the temperature / humidity sensor 1031z are provided with defect determination sensors 1032a, 1032b, 1032c, 1032g, and 1032z as electric sensors, respectively. Yes.

  Similar to the state output device 1, the state output device 1001 includes a display unit 1007, motor drivers 1131a, 1131b, 1131c, and 1131g. Similarly to the state output device 1, the state output device 1001 includes photocouplers 1101x and 1101y.

  In addition, the status output device 1001 includes a main control unit 1005. The main control unit 1005 controls each unit of the state output device 1001 such as the display unit 1007, the motor drivers 131a, 131b, and 131c, and the photocouplers 101x and 101y.

  In the status output system 1000, the failure determination sensors 1032a, 1032b, 1032c, 1032g, and 1032z are the operation members of the air conditioner, the cleaning motor 1031a, the wind direction left and right motor 1031b, the wind improving lower motor 1031c, the fan motor 1031g, and the temperature and humidity. Each of the sensors 1031z detects whether or not it has failed.

  The defect determination sensors 1032a, 1032b, 1032c, 1032g, and 1032z are each connected to the main control unit 1005 by wire. The main control unit 1005 receives the determination results from the defect determination sensors 1032a to 10z, determines which motor 1031a to g and the temperature / humidity sensor 1031z are out of order, and displays the determination result on the display unit 1007. Display.

  In addition, the configuration of the state output system 1000, that is, a failure determination sensor 1032 (1032a to 1032g, 1032z) as an electric sensor is attached to each component (each operation member such as the cleaning motor 1031a) of the apparatus, and the detection result of each electric sensor. However, there is a problem that the cost of the electric sensor is high and the wiring becomes complicated. Furthermore, since it is necessary to always operate each electric sensor in order to detect a failure of each component, even if the power consumption of each electric sensor alone is small, the overall power consumption of the state output device 1001 is There is a problem of growing.

  On the other hand, in the state output system 100 of this embodiment, as shown in FIG. 1, the wireless detectors 32 a to 32 g are indirectly connected via wireless communication using radio waves with the wireless transmission / reception unit 2 included in the state output device 1. In addition, information communication with the main control unit 5 is performed. In this respect, the status output system 100 of the present embodiment is different from the status output system 1000 of the comparative example shown in FIG. 10 in that the defect determination sensor 1032 (1032a to 1032g, 1032z) is connected to the main control unit 1005 and wired. This is different from directly performing information communication with the main control unit 5.

  That is, in the state output system 100, since the communication between the wireless transmission / reception unit 2 and the wireless detectors 32a to 32g is performed by wireless communication, compared to the communication in the state output system 1000 of the comparative example, Wiring complexity can be suppressed.

  Further, in the status output system 100, since the wireless transmission / reception unit 2 and the wireless detectors 32a to 32g can be realized by RFID (passive contactless authentication tag), the motor 31a is used only when failure detection is necessary. ˜31 g of failure can be detected. Therefore, power consumption can be reduced compared to the case where failure detection of each component is performed using an electric sensor (that is, an active type (always driven detection sensor)) as in the state output system 1000.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIG. For convenience of explanation, members similar to those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. When the configuration of the status output system 100 of the present embodiment is shown as a functional block diagram, the configuration is the same as the configuration shown in FIG.

  In FIG. 7, the top view showing the radio | wireless detector 42 which detects the overcurrent in the motor 31 as a radio | wireless detector of this embodiment is shown.

  The wireless detector (signal transmission device) 42 according to the present embodiment has the wireless detector 42 provided with a permanent magnet 41, and the permanent magnet 41 forms a part of the antenna 35. It is different from the machine 32.

(Configuration of wireless detector 42)
The wireless detector 42 includes a transmission / reception unit 33 including an IC unit 34 and an antenna 35, and a wireless communication control unit 40.

  The wireless communication control unit 40 includes a permanent magnet 41 that is movable in a direction in which the antenna 35 is disconnected. Further, the permanent magnet 41 forms a part of the antenna 35. As a result, when a magnetic force is generated, the permanent magnet 41 moves, thereby causing a break in the antenna 35.

(Failure detection method by wireless detector 42)
Next, a method for detecting a failure of the motor 31 by the wireless detector 42 will be described. As shown in FIG. 7, the wireless detector 42 is disposed so that the wireless communication control unit 40 is close to the lead wire 43 provided in the motor 31.

  When an overcurrent exceeding the first threshold value, which is a predetermined current larger than the current during normal energization, flows in the lead wire 43, a larger magnetic force is generated around the lead wire 43 than during normal energization. To do. The permanent magnet 41 in the wireless communication control unit 40 repels the generated magnetic force and moves in the direction (in the direction of the arrow in FIG. 7) that causes the antenna 35 to be disconnected. Thereby, the antenna 35 is disconnected.

  Therefore, when an overcurrent greater than or equal to the first threshold value flows through the lead wire 43, the radio wave receiving unit 22 cannot receive identification information from the wireless detector 42. Thereby, similarly to the state output system 100 of the first embodiment, it is possible to detect that an overcurrent greater than or equal to the first threshold value flows through the lead wire 43.

  The permanent magnet 41 has a magnetic force between the permanent magnet 41 and the holding portion holding the permanent magnet 41 so that the permanent magnet 41 moves only when an overcurrent greater than or equal to the first threshold value flows through the lead wire 43. What is necessary is just to determine in consideration of the frictional force generated between them.

(Effect of the wireless detector 42)
In the wireless detector 32 of the first embodiment, whether or not the temperature of the motor 31 exceeds the first threshold is detected, and the presence or absence of a failure of the motor 31 is determined. That is, the wireless detector 32 is a detector that uses the temperature of the motor 31 as a detection target.

  On the other hand, in the wireless detector 42 of the second embodiment, it is detected whether or not the current flowing through the motor 31 exceeds the first threshold value, and whether or not the motor 31 has failed is determined. That is, the wireless detector 42 is a detector that uses the current of the motor 31 as a detection target.

  In general, in the state monitoring of each part of the device including the motor, the current flowing through the part is a physical quantity that is important for preventive maintenance as well as the temperature of the part. It is useful to detect failure of parts.

[Modification]
In the status output system 100, the physical quantity to be detected by the wireless detector may be a physical quantity other than temperature (humidity) and current.

  For example, voltage, frequency, rotation speed, vibration level (amplitude, speed, acceleration), torque, noise, and the like can also be cited as important physical quantities for preventive maintenance of the motor. Therefore, a wireless detector having still another configuration capable of detecting whether or not these physical quantities are equal to or greater than a first threshold that is a predetermined value may be used as the wireless detector in the state output system 100. Good.

[Embodiment 3]
The following will describe another embodiment of the present invention with reference to FIGS. For convenience of explanation, members similar to those in the first and second embodiments are given the same reference numerals and explanation thereof is omitted.

(Configuration of status output system 200)
FIG. 8 is a functional block diagram illustrating a schematic configuration of the state output system 200 of the present embodiment. In the state output system 200, when the main controller 5 determines that the motors 31a to 31g are out of order by the failure determination unit 52, the main controller 5 calculates the estimated repair cost required for replacing the motors 31a to 31g. A portion 55 is further provided. The storage unit 6 stores a parts list 60. The state output system 200 of the present embodiment is different from the state output system 100 of the first and second embodiments in these points.

  In the same manner as the status output system 100 of the first and second embodiments, the status output system 200 detects “failed estimated cost” as the cost required for replacement of the failed component in addition to detecting the failed component. It can be calculated by the process shown in FIG.

(Flow of processing for failure detection and repair cost calculation in the status output system 200)
An example of the flow of processing for failure detection and repair cost calculation in the state output system 200 will be described.

  FIG. 9 is a flowchart illustrating an example of a flow of processing for failure detection and repair cost calculation in the state output system 200. In addition, about the failure detection processing shown in steps S11 to S19 in the state output system 200, the failure detection in the state output system 100 of the first embodiment shown in steps S1 to S9 in FIG. Since this is the same as the above process, the description thereof is omitted.

  In the state output system 200, the failure determination unit 52 receives the detection determination result from the reception availability determination unit 23, determines whether or not the motor 31 (31a to 31g) has a failure, and displays a failure determination result indicating the determination result. In addition to the transmission function stop unit 53 and the determination result output unit 54, the information is transmitted to the estimate calculation unit 55.

  Based on the failure determination result received from the failure determination unit 52, the estimate calculation unit 55 identifies the motor 31 (31a to 31g) that has been determined to be failed, and the total number of failed motors is “to be replaced”. It is set as “the number of parts” (step S20). For example, consider a case where two motors, that is, the motor 31b and the motor 31g are determined to have failed, and the number of parts to be replaced is set to “2”.

  Subsequently, the estimate calculation unit 55 acquires the price per motor 31 from the parts list 60 stored in the storage unit 6 and sets it as “price / piece of parts to be replaced” (step S21). . The parts list 60 includes data of catalog information (specifications, dimensions, weight, price, etc.) for each part of the apparatus. That is, the parts list 60 includes at least price data for each part of the apparatus. Here, a case where the price per motor 31a and 31g is set to “1,000 yen / piece” is considered.

The estimate calculating unit 55 uses the data of “number of parts to be replaced” and “price / piece of parts to be replaced” set in the above,
(Estimated repair cost) = (Number of parts to be replaced) x (Price of parts to be replaced / pieces)
The “repair estimated cost” as the cost required for replacement of the failed part is calculated (step S22). For example, applying the values listed above,
(Estimated repair cost) = (2) × (1,000 yen / piece) = 2,000 yen Assumed repair cost for failure of the motor 31b and the motor 31g in the state output system 200 is calculated (step S22). ). The calculation formula for the estimated repair cost shown above is an example. For example, the estimated repair cost for each type is calculated for each part type using the above formula, and the total value is calculated as the final estimated repair cost. May be.

  The estimate calculation unit 55 transmits estimate information indicating the estimated repair cost to the determination result output unit 54.

  The determination result output unit 54 transmits the estimation information input from the estimate calculation unit 55 to the display unit 7 in addition to the failure determination result transmitted from the failure determination unit 52, and outputs it as an image. Thereby, in addition to the faulty part, the repair estimated cost of the faulty part is displayed on the display unit 7.

(Effect of status output system 200)
In the status output system 200, in addition to detecting a failed part, a repair estimated cost for the failed part is calculated.

  As a result, the user of the status output system 200 can easily check the repair estimated cost of the failed part in each part of the apparatus, which is associated with the investigation of the failed part by the maintenance staff of the apparatus as in the past. It is possible to shorten the time required for estimating replacement parts. As a result, the status output system 200 is beneficial in this respect because it reduces the time required to repair the device.

[Example of software implementation]
The control blocks of the status output device 1 (in particular, the read command unit 51, the failure determination unit 52, the transmission function stop unit 53, the determination result output unit 54, and the estimate calculation unit 55) are formed in an integrated circuit (IC chip) or the like. It may be realized by a logic circuit (hardware), or may be realized by software using a CPU (Central Processing Unit).

  In the latter case, the status output device 1 includes a CPU that executes instructions of a program that is software that realizes each function, and a ROM (Read Only Memory) in which the program and various data are recorded so as to be readable by a computer (or CPU). Alternatively, a storage device (these are referred to as “recording media”), a RAM (Random Access Memory) that expands the program, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The program may be supplied to the computer via an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.

[Summary]
The state output device (1) according to the first aspect of the present invention is a signal transmission device that is disposed at or near the operation member (motor 31) and whose signal transmission function is reduced by a physical change caused by a failure of the operation member. A detection availability determination unit (reception availability determination unit 23) that determines whether or not the intensity of a signal transmitted from the (wireless detector 32) is reduced to a predetermined value or less, and the detection availability determination unit include: When it is determined that the strength has decreased to a predetermined value or less, a failure determination unit that determines that the operation member corresponding to the signal transmission device that has transmitted the signal or is supposed to transmit has failed. (52) and a determination result output unit (54) for outputting the determination result of the failure determination unit.

  According to the above configuration, the signal transmission function of the signal transmission device is degraded due to a physical change caused by a failure of the operation member. That is, since the signal transmission device is disposed at or near the operating member, the signal transmission function is degraded when the operating member fails.

  In the state output device, the failure determination unit transmits or transmits the signal when it is determined by the detection possibility determination unit that the intensity of the signal transmitted from the signal transmission device has decreased to a predetermined value or less. It is determined whether or not the operating member corresponding to the signal transmission device that is supposed to be malfunctioning.

  Therefore, the status output device can determine whether or not the operating member has failed only by determining the degree of decrease in the signal strength accompanying the physical change of the signal transmission device. That is, it is possible to easily and reliably determine whether or not the operating member has failed.

  In the state output device, the determination result output unit outputs the determination result by the failure determination unit. Therefore, it is possible to notify the user who uses the state output device of the presence or absence of a failure of the operating member.

  Therefore, the status output device can easily and reliably determine whether or not the operating member has failed, and can easily and reliably identify the failed operating member. .

  In the state output device (1) according to the second aspect of the present invention, in the first aspect, at least one signal transmission device is associated with each of the plurality of operation members, and the detection possibility determination is performed. The unit preferably determines whether or not the strength of a signal transmitted from each of the plurality of signal transmission devices has decreased to a predetermined value or less.

  According to said structure, at least 1 signal transmission apparatus is matched and arrange | positioned with respect to each of a some operating member. In addition, the detectability determination unit determines whether or not the strength of a signal transmitted from each of the plurality of signal transmission devices has decreased to a predetermined value or less.

  Therefore, since the state output device can perform the determination by the above-described detection possibility determination unit for each of the plurality of operation members, it is possible to reliably determine which of the plurality of operation members is out of order. can do. In addition, even when there are a plurality of the same operating members, for example, the state output device can reliably determine which of the operating members is out of order.

  In the state output device (1) according to aspect 3 of the present invention, in the above aspect 1 or 2, the detection availability determination unit detects a signal transmitted from the signal transmission device via a wireless communication medium. It is preferable.

  According to said structure, a detection decision | availability determination part detects the signal transmitted from a signal transmitter via a wireless communication medium.

  Accordingly, since it is not necessary to connect the state output device and the signal transmission device by wire, it is possible to prevent the wiring in the state output device from becoming complicated.

  As described above, the state output device can perform signal detection determination and, in turn, determination of the presence or absence of a failure of the operating member under an easy configuration. In addition, the said structure is especially useful when performing the presence or absence determination of the failure with respect to a several operating member.

  In the state output device (1) according to the aspect 4 of the present invention, in any one of the aspects 1 to 3, when the failure determination unit determines that the operation member has failed, It is preferable to further include an estimate calculation unit (55) for calculating a repair estimate cost required for replacing the operating member.

  According to the above configuration, the state output device further includes an estimate calculation unit that calculates a repair estimated cost required for replacement of the operation member when the failure determination unit determines that the operation member has failed. Yes.

  Therefore, in addition to detecting the failure of the operating member, the state output device can calculate the repair estimated cost of the operating member determined to be faulty.

  Therefore, the status output device can present the estimated repair cost together with the presence or absence of a failure of the operating member to the user. Therefore, the user can easily recognize the repair estimated cost of the operating member while recognizing that the operating member has failed. In addition, since the estimated repair cost can be easily confirmed, the period required for repairing the moving member can be shortened.

  Further, in the state output device (1) according to the fifth aspect of the present invention, in any one of the first to fourth aspects, the physical change accompanying the failure of the operation member in the signal transmission device is irreversible. It is preferable.

  According to said structure, the physical change accompanying the failure of the operation | movement member in a signal transmitter is irreversible.

  Therefore, in the signal transmission device, without using a complicated mechanism for realizing a reversible configuration, for example, a signal transmission function by an irreversible and simple physical phenomenon such as disconnection of a wiring included in the signal transmission device. Decrease is caused.

  Therefore, the status output device can easily identify the failure of the operating member.

  In the state output device (1) according to the aspect 6 of the present invention, the signal transmission device includes a plurality of transmission units (transmission / reception units 33) that transmit the signals, and signals transmitted from the plurality of transmission units are transmitted. When all of them cannot be detected, the failure determination unit preferably determines that a communication failure has occurred without determining that the operating member has failed.

  According to the above configuration, when the failure determination unit fails to detect all of the signals transmitted from the plurality of transmission units, it does not determine that the operation member is defective, and a communication failure occurs. It is determined that

  Therefore, for example, since there is a shield between the state output device and the signal transmission device, it is determined that the operation member corresponding to the signal transmission device is out of order because the transmission from the signal transmission device cannot be detected. Thus, it is possible to prevent erroneous determination of a failure that may occur in the case of a signal transmission device including only one transmission unit. That is, in addition to the presence / absence of a failure of the operating member, the state of the operating member that is the detection target can be determined more accurately.

  In the state output device (1) according to aspect 7 of the present invention, in any one of the aspects 1 to 6, the signal transmission device is preferably a passive contactless authentication tag.

  According to the above configuration, since the signal transmission device is a passive contactless authentication tag, the status output device detects the failure of the operating member by activating the authentication tag only when failure detection is necessary. It can be carried out. Therefore, for example, power consumption can be reduced as compared with a case where an active detection sensor that is always driven for detecting a failure of the operating member is attached to the operating member.

  Further, the control method of the state output device (1) according to the aspect 8 of the present invention is a signal transmission that is disposed at or near the operation member and whose signal transmission function is reduced due to a physical change caused by the failure of the operation member. In the detection possibility determination step for determining whether or not the intensity of the signal transmitted from the apparatus has decreased to a predetermined value or less, and in the detection possibility determination step, it is determined that the signal intensity has decreased to a predetermined value or less. A failure determination step for determining that the operation member corresponding to the signal transmission device that has transmitted or is supposed to transmit the signal has failed, and a determination result in the failure determination step is output. A determination result output step.

  According to said structure, it can be determined easily and reliably whether the action | operation member is out of order similarly to said aspect 1. FIG. Therefore, the user can easily and reliably identify the failed operating member.

  Further, in the state output system (100, 200) according to the ninth aspect of the present invention, the state output device (1) according to any one of the first to seventh aspects and the operation member or the vicinity thereof are disposed, It is preferable to include a signal transmission device in which a signal transmission function is lowered due to a physical change caused by a failure of the operation member.

  According to said structure, it can be determined easily and reliably whether the operation | movement member is out of order like the status output apparatus as described in any one of said aspect 1-7. Therefore, the user can easily and reliably identify the failed operating member.

  In addition, the state output device (1) according to each aspect of the present invention may be realized by a computer, and in this case, the state is obtained by operating the computer as each unit included in the state output device (1).
