Specifically, the air conditioning control device 20 determines a control signal to be output to the compressor 12, the outdoor blower 16, and each of the indoor blowers 171 to 174 constituting the air conditioner 11, based on the target temperature TB.

  Subsequently, in step S330, the air conditioning control device 20 outputs the control signal determined in step S320 to each functional product of the air conditioner 10. That is, the air-conditioning control device 20 controls each functional product of the air-conditioning device 10 so that the blowing temperature and the blowing amount of the air blown into the room are in desired states. Thereby, in the air conditioner 10, the air adjusted to a desired temperature by the evaporator 15 or the like is blown out to the air conditioning zones Z1 to Z4 in the room through the air conditioning ducts 10C to 10F.

  Next, an abnormality diagnosis process executed by the abnormality diagnosis device 30 will be described with reference to FIG. The abnormality diagnosis device 30 performs, for example, the abnormality diagnosis process illustrated in FIG. 13 at a predetermined cycle while the operation switch 221 is maintained in the ON state.

  As shown in FIG. 13, in step S400, the abnormality diagnosis device 30 determines whether the air conditioning state is stable. Specifically, the abnormality diagnosis device 30 determines whether a predetermined period has elapsed since the operation switch 221 was set to the ON state or the indoor set temperature Tset was changed. The predetermined period is set to, for example, a necessary time required to bring the indoor temperature to the set temperature Tset in a state where the air conditioner 10 has no abnormality.

  When the air-conditioning state is stable, the abnormality diagnosis device 30 acquires various kinds of information from the outside in step S410. Specifically, the abnormality diagnosis device 30 acquires the device status information from the air conditioning control device 20 via the electric communication line CN, and acquires the position specifying information and the terminal information from the information terminals 60A to 60C. It is preferable that the abnormality diagnosis device 30 be configured to store the device status information, the position identification information, and the terminal information acquired by the information acquisition unit 31 in the information storage unit 34. According to this, by statistically utilizing the information stored in the information storage unit 34 as time-series information, it becomes possible to reduce variations in passenger attributes, other disturbances, and the like.

  Subsequently, the abnormality diagnosis device 30 diagnoses whether the air conditioner 10 has an abnormality based on the device state information. Specifically, in step S420, abnormality diagnosis device 30 determines whether the absolute value of the temperature difference between set temperature Tset and internal temperature Tr is smaller than a preset temperature threshold value ΔTth. The temperature threshold value ΔTth is set to, for example, a temperature (for example, 2 ° C.) or more at which an occupant's thermal sensation is affected.

  When the absolute value of the temperature difference between the set temperature Tset and the inside air temperature Tr is smaller than the temperature threshold value ΔTth, in step S430, the abnormality diagnosis device 30 diagnoses that the air conditioner 10 is normal and exits the abnormality diagnosis process.

  On the other hand, if the absolute value of the temperature difference between the set temperature Tset and the internal temperature Tr is equal to or greater than the temperature threshold ΔTth, the abnormality diagnosis device 30 diagnoses that some abnormality has occurred in the air conditioner 10 in step S440.

  When there is an abnormality in the air conditioner 10, the abnormality diagnosis device 30 executes an abnormality identification process of identifying an abnormality occurrence location where an equipment abnormality has occurred in the air conditioner 10 in step S450. The abnormality diagnosis device 30 identifies the location where the abnormality has occurred using the position identification information and the air conditioning suitability information. Hereinafter, an example of the abnormality identification processing will be described with reference to FIG.

  As illustrated in FIG. 14, the abnormality diagnosis device 30 determines in step S500 whether the state of the refrigeration cycle is a cycle state according to a blower signal that is a control signal output to each of the indoor blowers 171 to 174. judge.

  Here, when the indoor blowing system is normal, the blowing capacity of each of the indoor blowers 171 to 174 becomes the blowing capacity according to the blower signal, and the pressure of the refrigerant passing through the evaporator 15 and the air after passing through the evaporator 15. Becomes the pressure and temperature according to the blower signal. For this reason, when the refrigeration cycle is in the cycle state according to the blower signal, it is considered that no abnormality has occurred in the indoor ventilation system.

  Therefore, when the state of the refrigeration cycle is a cycle state corresponding to the blower signal, the abnormality diagnosis device 30 diagnoses in step S510 that an abnormality has occurred in a functional product other than the indoor ventilation system. That is, the abnormality diagnosis device 30 identifies a functional product other than the indoor ventilation system as a location where an abnormality has occurred.

  On the other hand, when an abnormality has occurred in the indoor blowing system, the blowing stress of each of the indoor blowers 171 to 174 becomes lower than the blowing capacity according to the blower signal, and the pressure of the refrigerant in the evaporator 15 decreases and the evaporator 15 evaporates. The temperature of the air after passing through the vessel 15 decreases. For this reason, when the state of the refrigeration cycle is not the cycle state according to the blower signal, it is considered that an abnormality has occurred in the indoor ventilation system.

  Therefore, when the state of the refrigeration cycle is not the cycle state, the abnormality diagnosis device 30 proceeds to the determination processing in step S520.

  In step S520, abnormality diagnosis device 30 determines whether there is a correlation between the position of the passenger in the room and the suitability of the air-conditioning state, based on the position specifying information and the air-conditioning suitability information obtained from information terminals 60A to 60C. I do.

  For example, when the positions of the information terminals 60A to 60C in which the air-conditioning state is inappropriate are biased to predetermined positions in the room, the abnormality diagnosis device 30 determines that there is a correlation between the position of the passenger in the room and the suitability of the air-conditioning state. judge. Further, for example, when the positions of the information terminals 60A to 60C in which the air-conditioning state is inappropriate are dispersed in the room, the abnormality diagnosis device 30 determines that there is no correlation between the position of the passenger in the room and the suitability of the air-conditioning state. I do.

  When there is no correlation between the position of the occupant in the room and the suitability of the air-conditioning state, it is considered that a difference between the inside air temperature Tr and the set temperature Tset occurs in the whole room. Such a phenomenon often occurs when the flow rate of the air passing through the evaporator 15 is reduced due to clogging of the filter 18 or the like.

  Therefore, when there is no correlation between the position of the occupant in the room and the suitability of the air-conditioning state, the abnormality diagnosis device 30 diagnoses that an abnormality has occurred in the filter 18 in step S530. That is, the abnormality diagnosis device 30 specifies the filter 18 as an abnormality occurrence location.

  On the other hand, when there is a correlation between the position of the occupant in the room and the suitability of the air-conditioning state, it is considered that a difference between the inside air temperature Tr and the set temperature Tset occurs at a specific place in the room. Such a phenomenon often occurs when a part of each of the indoor blowers 171 to 174 has failed.

  Therefore, if there is a correlation between the position of the occupant in the room and the suitability of the air-conditioning state, the abnormality diagnosis device 30 diagnoses that an abnormality has occurred in each of the indoor blowers 171 to 174 in step S540. That is, the abnormality diagnosis device 30 specifies each of the indoor blowers 171 to 174 as an abnormality occurrence location.

  If an abnormality has occurred in each of the indoor blowers 171 to 174, the abnormality diagnosis device 30 executes a detailed identification process of identifying which of the indoor blowers 171 to 174 has an abnormality in step S550. Hereinafter, the detail specifying process will be described with reference to FIG.

  As shown in FIG. 15, in step S600, the abnormality diagnosis device 30 determines whether or not the content of the air conditioning state in the information terminals 60A to 60C is different between the left and right sides of the room. As a result, when the content of the appropriateness of the air-conditioning state is the same for the left and right sides of the room, the abnormality diagnosis device 30 skips the processing of steps S610 to S630 and shifts to the processing of step S640. In addition, when the content of the appropriateness of the air conditioning state is different between the left and right in the room, the abnormality diagnosis device 30 proceeds to step S610.

  In step S610, abnormality diagnosis device 30 determines whether any of the information terminals 60A to 60C indicating an inappropriate air-conditioning state is biased toward the left side of the room. As a result, when one of the information terminals 60A to 60C indicating an inappropriate air-conditioning state is biased toward the left side of the room, an abnormality occurs in the second indoor blower 172 and the fourth indoor blower 174 installed on the left side of the room. Likely to be.

  Therefore, if any of the information terminals 60A to 60C indicating an inappropriate air conditioning state is biased to the left side of the room, the abnormality diagnosis device 30 determines in step S620 that the second indoor blower 172 and the fourth indoor blower 174 have an abnormality. An abnormal flag indicating that the possibility that the error has occurred is set.

  On the other hand, in the case where one of the information terminals 60A to 60C indicating an inappropriate air-conditioning state is biased to the right side of the room, an abnormality has occurred in the first indoor blower 171 and the third indoor blower 173 installed on the right side of the room. Probability is high. For this reason, when the terminal indicating the inappropriate air-conditioning state among the information terminals 60A to 60C is biased to the right in the room, the abnormality diagnosis device 30 sends the first indoor blower 171 and the third indoor blower 173 to each other in step S630. An abnormality flag indicating that there is a high possibility that an abnormality has occurred is set.

  Subsequently, in step S640, the abnormality diagnosis device 30 determines whether the content of the air conditioning state in the information terminals 60A to 60C is different between before and after the room. As a result, when the content of the appropriateness of the air-conditioning state is the same before and after the room, the abnormality diagnosis device 30 skips the processing of steps S650 to S670 and shifts to the processing of step S680. If the content of the appropriateness of the air-conditioning state is different before and after the room, the abnormality diagnostic device 30 proceeds to step S650.

  In step S650, abnormality diagnosis device 30 determines whether or not one of information terminals 60A to 60C indicating an inappropriate air-conditioning state is biased toward the front in the room. As a result, in the case where one of the information terminals 60A to 60C indicating an inappropriate air-conditioning state is biased toward the front of the room, an abnormality occurs in the first indoor blower 171 and the second indoor blower 172 installed at the front of the room. Likely to be.

  Therefore, if any of the information terminals 60A to 60C indicating an inappropriate air conditioning state is biased toward the front of the room, the abnormality diagnosis device 30 determines in step S660 that the first indoor blower 171 and the second indoor blower 172 have an abnormality. An abnormal flag indicating that the possibility that the error has occurred is set.

  On the other hand, when one of the information terminals 60A to 60C indicating an inappropriate air conditioning state is biased toward the rear of the room, an abnormality occurs in the third indoor fan 173 and the fourth indoor fan 174 installed at the rear of the room. Likely to be. Therefore, when the information terminal 60A to 60C that shows an inappropriate air conditioning state is biased toward the rear side of the room, the abnormality diagnosis device 30 sends the third indoor blower 173 and the fourth indoor blower 174 to each other in step S670. An abnormality flag indicating that there is a high possibility that an abnormality has occurred is set.

  Subsequently, in step S680, the abnormality diagnosis device 30 specifies which of the indoor blowers 171 to 174 has an abnormality. For example, the abnormality diagnosis device 30 refers to the abnormality flags set in steps S620, S630, S660, and S670, and identifies, among the indoor blowers 171 to 174, one in which two abnormality flags are set as an abnormality occurrence location. I do.

  As described above, the abnormality diagnosis device 30 is configured such that, when the information terminals 60A to 60C that issue the air-conditioning suitability information that makes the indoor air-conditioning state unsuitable are located in a specific air-conditioning zone among the plurality of air-conditioning zones Z1 to Z4, A functional product corresponding to a specific air-conditioning zone is specified as an abnormal occurrence location.

  The above is the description regarding the abnormality identification processing. When the abnormality identification processing is completed, the abnormality diagnosis device 30 determines in step S460 of FIG. 13 that the information terminal and the maintenance staff of the route bus 2 operating company provide recommended actions and the like according to the diagnosis result and the abnormality occurrence location. Notify the information terminal etc. that it has.

  For example, if the location of the abnormality is the filter 18, the abnormality diagnosis device 30 notifies the information terminal or the like owned by the operating company of the route bus 2 that the replacement of the filter 18 is a recommended action. In addition, for example, when the location of the abnormality is the indoor blowers 171 to 174 or the like, the abnormality diagnosis device 30 uses an information terminal or the like owned by the operating company of the route bus 2 as a recommended action to inspect the indoor blowers 171 to 174 or the like. Notify.

  According to the air conditioning system 1 described above, it is configured to diagnose the presence or absence of an abnormality of the air conditioner 10 using not only the device state information on the operation state of the air conditioner 10 but also the position specifying information for specifying the position of the occupant. ing. According to this, since the position specifying information for specifying the position of the occupant is used to diagnose the abnormality of the air conditioner 10, a dedicated sensor for specifying the abnormality of the air conditioner 10 is added. Without this, it is possible to diagnose whether or not the air conditioner 10 is abnormal.

  In particular, in the air conditioning system 1 of the present embodiment, the information acquisition unit 31 of the abnormality diagnosis device 30 includes, in addition to the position identification information, information regarding the indoor air conditioning state set in the information terminals 60A to 60C possessed by the passenger. It is configured to be able to acquire terminal information. Then, the diagnosis unit 33 of the abnormality diagnosis device 30 diagnoses whether or not the air conditioner 10 has an abnormality using the device state information, the position identification information, and the terminal information.

  As described above, if the configuration is such that information on the indoor air-conditioning state can be obtained from the information terminals 60A to 60C possessed by the passenger, the information terminals 60A to 60C can function as a detection unit that detects the indoor air-conditioning state. . Then, if the presence or absence of an abnormality of the air conditioner 10 is diagnosed using the device state information, the position identification information, and the terminal information, the air conditioner 10 can be installed without adding a dedicated sensor for identifying the abnormality of the air conditioner 10. It is possible to diagnose the presence or absence of an abnormality.

  The terminal information includes air conditioning suitability information indicating the suitability of the indoor air condition. Then, the diagnosis unit 33 detects the device abnormality by the abnormality diagnosis of the air conditioner 10 based on the device state information, and uses the position identification information and the air conditioning suitability information to determine the abnormality occurrence location where the device abnormality has occurred in the air conditioner 10. It is configured to identify.

  According to this, it is possible to specify a functional product in which an abnormality has occurred from among a plurality of functional products constituting the air conditioner 10 by using the air conditioning suitability information included in the terminal information. In this case, there is an advantage that it becomes easy to respond to the abnormality of the air conditioner 10.

  Here, the air conditioner 10 of the present embodiment is configured to be able to blow air for each of a plurality of air conditioning zones Z1 to Z4 set indoors. Such an air conditioner 10 tends to have a more complicated configuration than the air conditioner 10 that blows air into a single air conditioning zone, and an abnormality occurs in any of a plurality of functional products constituting the air conditioner 10. It is difficult to determine whether or not.

  On the other hand, when the information terminals 60A to 60C that emit air-conditioning suitability information indicating that the air-conditioning state is inappropriate are located in a specific air-conditioning zone, the abnormality diagnosis device 30 has a function corresponding to the specific air-conditioning zone. The product is specified as an abnormality occurrence location. According to this, even in the air conditioner 10 that blows out air to the plurality of air conditioning zones Z1 to Z4, the location where the abnormality occurs in the air conditioner 10 without adding a dedicated sensor for identifying the abnormality of the air conditioner 10 Can be specified.

  Further, the abnormality diagnosis device 30 is installed outside the route bus 2 which is a moving body. As described above, if the abnormality diagnosis device 30 is installed outside the route bus 2, it is possible to change the content of the abnormality diagnosis of the air conditioner 10 without changing the devices mounted on the route bus 2. . For example, even if the device is already sold in the market, the content of the abnormality diagnosis can be changed without changing the sold device.

(Modification of First Embodiment)
In the above-described first embodiment, an example in which the indoor positioning device 50 executes the position specifying process has been described, but the present invention is not limited to this. The indoor positioning device 50 may be configured not to execute the position specifying process.

  In the first embodiment described above, the abnormality diagnosis device 30 is configured to acquire the attribute information from the information terminals 60A to 60C. The passenger's thermal sensation may differ depending on the gender and age included in the attribute information. Therefore, it is desirable to re-evaluate the air conditioning suitability information using the gender and age included in the attribute information. That is, it is preferable that the abnormality diagnosis device 30 be configured to execute the reevaluation process of changing the propriety of the air conditioning state included in the air conditioning propriety information using the attribute information.

  Here, regarding gender, women tend to have lower metabolic calories than men, and tend to feel comfortable in a warm environment. For this reason, for example, when acquiring the air conditioning suitability information indicating that the air conditioning state is slightly cold from the information terminals 60A to 60C held by the woman, the abnormality diagnosis device 30 performs a process of appropriately changing the air conditioning state of the air conditioning suitability information. It is desirable that it be configured to execute.

  As for age, the metabolic caloric value tends to decrease in the order of a young age group (for example, less than 30 years old), a middle age group (for example, 30 to 59 years old), and an older age group (for example, 60 years old or older), As the age increases, the warm environment tends to feel comfortable. For this reason, for example, when acquiring the air-conditioning suitability information that the air-conditioning state is slightly hot from the information terminals 60A to 60C held by the passengers of the young age group, the abnormality diagnosis device 30 appropriately adjusts the air-conditioning state of the air-conditioning suitability information. It is desirable to have a configuration for executing the process of changing to.

  In the first embodiment described above, when the air conditioner 10 is diagnosed as having an abnormality in the abnormality determination process, the information terminal in which the operating company of the route bus 2 holds the diagnosis result, a recommended action, etc. corresponding to the location where the abnormality has occurred. Although an example of notifying the user has been described, the present invention is not limited to this.

  For example, when the abnormality diagnosis device 30 diagnoses that the air conditioner 10 has an abnormality in the abnormality determination process, the abnormality diagnosis device 30 notifies the air conditioner controller 20 of the abnormality occurrence location and notifies the driver or the like via the notification unit 223. A configuration for notifying an abnormality of the air conditioner 10 may be adopted. This is the same in the following embodiments.

(2nd Embodiment)
Next, a second embodiment will be described with reference to FIGS. The present embodiment is different from the first embodiment in that an abnormality identification process for identifying an abnormality occurrence location in the air conditioner 10 using the position identification information is executed. In the present embodiment, portions different from the first embodiment will be mainly described, and description of the same portions as the first embodiment may be omitted.

  Hereinafter, the abnormality identification processing executed by the abnormality diagnosis device 30 of the present embodiment will be described with reference to FIG. Note that the processing of steps S700 and S710 shown in FIG. 16 is the same as the processing of steps S500 and S510 shown in FIG.

  As shown in FIG. 16, in step S700, the abnormality diagnosis device 30 determines whether the state of the refrigeration cycle is a cycle state according to the blower signal. As a result, when the state of the refrigeration cycle is a cycle state corresponding to the blower signal, the abnormality diagnosis device 30 diagnoses in step S710 that an abnormality has occurred in a functional product other than the indoor ventilation system.

  On the other hand, when the state of the refrigeration cycle is not the cycle state corresponding to the blower signal, the abnormality diagnosis device 30 proceeds to the determination processing of step S720. In step S720, abnormality diagnosis device 30 determines whether or not there is a bias in the position of the passenger in the room based on the position identification information acquired from information terminals 60A to 60C.

  For example, when the positions of the information terminals 60A to 60C are biased to predetermined positions in the room, the abnormality diagnosis device 30 determines that the position of the occupant in the room is biased. In addition, for example, when the positions of the information terminals 60A to 60C are dispersed in the room, the abnormality diagnosis device 30 determines that there is no bias in the position of the passenger in the room.

  When there is no deviation in the position of the occupant in the room, it is considered that a difference between the inside air temperature Tr and the set temperature Tset occurs in the entire room. Such a phenomenon often occurs when the flow rate of the air passing through the evaporator 15 is reduced due to clogging of the filter 18 or the like.

  Therefore, when there is no deviation in the position of the occupant in the room, the abnormality diagnosis device 30 diagnoses that an abnormality has occurred in the filter 18 in step S730. That is, the abnormality diagnosis device 30 specifies the filter 18 as an abnormality occurrence location.

  On the other hand, when the position of the occupant in the room is uneven, it is considered that a deviation between the inside air temperature Tr and the set temperature Tset occurs at a specific place in the room. Such a phenomenon often occurs when a part of each of the indoor blowers 171 to 174 has failed.

  Therefore, when there is a bias in the position of the occupant in the room, the abnormality diagnosis device 30 diagnoses that an abnormality has occurred in each of the indoor blowers 171 to 174 in step S740. That is, the abnormality diagnosis device 30 specifies each of the indoor blowers 171 to 174 as an abnormality occurrence location.

  When an abnormality has occurred in each of the indoor blowers 171 to 174, the abnormality diagnosis device 30 executes a detailed identification process for identifying which of the indoor blowers 171 to 174 has an abnormality in step S750. Hereinafter, the detail specifying process will be described with reference to FIG.

  As shown in FIG. 17, in step S800, the abnormality diagnosis device 30 determines whether or not the occupant is unevenly located on the left and right sides of the room. As a result, when the position of the occupant is the same in the left and right sides of the room, the abnormality diagnosis device 30 skips the processing of steps S810 to S830 and shifts to the processing of step S840. If the occupant is unevenly distributed on the left and right sides of the room, the abnormality diagnosis device 30 proceeds to step S810.

  In step S810, abnormality diagnosis device 30 determines whether or not the occupant is biased leftward in the room. As a result, when the occupant is biased to the left in the room, there is a high possibility that the first indoor blower 171 and the third indoor blower 173 installed on the right in the room are abnormal.

  Therefore, when the occupant is biased to the left side of the room, the abnormality diagnosis device 30 determines in step S820 that the first indoor blower 171 and the third indoor blower 173 are highly likely to have an abnormality. Set a flag.

  On the other hand, when the occupant is biased to the right in the room, it is highly likely that an abnormality has occurred in the second indoor blower 172 and the fourth indoor blower 174 installed on the left side in the room. Therefore, when the occupant is biased to the left side of the room, the abnormality diagnosis device 30 indicates in Step S830 that there is a high possibility that an abnormality has occurred in the second indoor blower 172 and the fourth indoor blower 174. Set an abnormal flag.

  Subsequently, in step S840, abnormality diagnosis device 30 determines whether or not the occupant is unevenly located in the front and rear of the room. As a result, when the position of the occupant is the same before and after the room, the abnormality diagnosis device 30 skips the processing of steps S850 to S870 and shifts to the processing of step S880. When the occupant is unevenly located in the front and rear of the room, the abnormality diagnosis device 30 proceeds to step S850.

  In step S850, abnormality diagnosis device 30 determines whether or not the occupant is biased toward the front in the room. As a result, when the occupant is biased toward the front in the room, there is a high possibility that an abnormality has occurred in the third indoor blower 173 and the fourth indoor blower 174 installed behind the room.

  Therefore, when the occupant is biased toward the front in the room, the abnormality diagnosis device 30 determines in step S860 that the third indoor blower 173 and the fourth indoor blower 174 are highly likely to have an abnormality. Set a flag.

  On the other hand, when the occupant is biased to the rear side of the room, it is highly likely that the first indoor blower 171 and the second indoor blower 172 installed at the front side of the room are abnormal. Therefore, when the occupant is biased to the front side in the room, the abnormality diagnosis device 30 indicates in Step S870 that there is a high possibility that an abnormality has occurred in the first indoor blower 171 and the second indoor blower 172. Set an abnormal flag.

  Subsequently, in step S880, the abnormality diagnosis device 30 specifies which of the indoor blowers 171 to 174 has an abnormality. For example, the abnormality diagnosis device 30 refers to the abnormality flags set in steps S820, S830, S860, and S870, and identifies, among the indoor blowers 171 to 174, one in which two abnormality flags are set as an abnormality occurrence location. I do.

  As described above, when the position of the occupant specified by the position specifying information is biased toward a position avoiding a specific part in the room, the abnormality diagnosis device 30 specifies the plurality of functional products constituting the air conditioner 10. Identify the functional product corresponding to the location as the location where the error occurred.

  Other configurations are the same as in the first embodiment. Since the air-conditioning system 1 according to the present embodiment has the same configuration as the first embodiment, it is possible to obtain the same operational effects as those of the first embodiment. .

  The abnormality diagnosis device 30 of the present embodiment detects a device abnormality by abnormality diagnosis of the air conditioner 10 based on the device state information, and responds to a specific location among a plurality of functional products constituting the air conditioner 10 using the position identification information. Function products to be specified are identified as abnormalities.

  According to this, it is possible to specify a functional product in which an abnormality has occurred from among a plurality of functional products constituting the air conditioner 10 using the position specifying information for specifying the position of the passenger. . In this case, there is an advantage that it becomes easy to respond to the abnormality of the air conditioner 10.

  In particular, the abnormality diagnosis device 30 according to the present embodiment is configured to identify a location where an abnormality has occurred in the air conditioner 10 using the position identification information without using the air conditioning suitability information. According to this, for example, even when the air conditioning suitability information is not set in the information terminals 60A to 60C, it is possible to specify the location where the abnormality of the air conditioner 10 has occurred.

(Modification of Second Embodiment)
In the above-described second embodiment, an example has been described in which the abnormality diagnosis device 30 acquires the position identification information from the information terminals 60A to 60C, but the present invention is not limited to this. The abnormality diagnosis device 30 may be configured to acquire position identification information from the indoor positioning device 50. According to this, even when the occupant boarding the route bus 2 does not have the information terminals 60A to 60C, it is possible to identify the location where the air conditioner 10 has an abnormality.

(Third embodiment)
Next, a third embodiment will be described with reference to FIG. The first embodiment is different from the first embodiment in that the information acquired by the information acquisition unit 31 is compared with the information stored in the information storage unit 34 to execute an abnormality identification process for identifying an abnormality occurrence location in the air conditioner 10. Is different. In the present embodiment, portions different from the first embodiment will be mainly described, and description of the same portions as the first embodiment may be omitted.

  The information storage unit 34 of the abnormality diagnosis device 30 stores in advance device status information, position identification information, terminal information, and device error data in which an error occurrence location is associated. The device abnormality data is, for example, data generated by an experiment, a simulator, or the like.

  The abnormality diagnosing device 30 compares the device status information, the position identification information, and the terminal information acquired by the information acquisition unit 31 with the device abnormality data stored in the information storage unit 34 to identify the location where the abnormality has occurred in the air-conditioning device 10. Execute abnormality identification processing. Hereinafter, the abnormality identification processing executed by the abnormality diagnosis device 30 of the present embodiment will be described with reference to FIG.

  As shown in FIG. 18, the abnormality diagnosis device 30 acquires various types of information from the outside in step S900. Specifically, the abnormality diagnosis device 30 acquires the device status information from the air conditioning control device 20 via the electric communication line CN, and acquires the position specifying information and the terminal information from the information terminals 60A to 60C. When the various information acquired in step S410 in FIG. 13 is stored in the information storage unit 34, the abnormality diagnosis device 30 reads the various information stored in the information storage unit 34.

  Subsequently, the abnormality diagnosis device 30 reads the device abnormality data stored in the information storage unit 34 in step S910. Specifically, the abnormality diagnosis device 30 reads the device status information, the position identification information, the terminal information, and the abnormality occurrence location stored in the information storage unit 34.
