To the next process, that is, the process of step S9.

On the other hand, when the data related to the received driving information is the abnormality occurrence data and the process of step S7 (abnormality process subroutine) is executed, the process returns to the main routine and shifts to the process of step S9.

When the process proceeds to step S9, it is determined in step S9 whether the system is stopped or terminated. Then, when the system is not stopped or terminated (N in step S9), the process returns to step S1 and the process is executed again. On the other hand, when the system is stopped / finished (Y in step S9), a series of processes is finished.

When the processing of the above step S7 (subroutine for abnormality processing) is executed, the received abnormality occurrence data is transferred to the web page (not shown) in step S11.
It is stored in the server and the next processing, that is, step S13

Under the control of the PU, it is displayed on the monitor 13 as a map or a figure showing an abnormality occurrence point), and the process proceeds to the next process, that is, the process of step S15.

When the process proceeds to step S15, in step S15, it is determined whether detailed information is necessary for the received abnormality occurrence data based on the content confirmation in step S13. If detailed information is required (Y in step S15), step S17
Process shifts to. On the other hand, when the detailed information is unnecessary (N in step S15), the process proceeds to step S23.

When the process proceeds to step S17, in step S17, the first control unit 9 is requested to transmit the detailed abnormality occurrence data related to the detailed information, and the process proceeds to the next process, that is, the process of step S19. Transition.

When the processing shifts to step S19, in step S19, it is judged whether or not the detailed abnormality occurrence data related to the detailed information transmitted from the first control unit 9 is received. If detailed abnormality occurrence data relating to the detailed information has not been received (step S19)
N), and waits until the detailed abnormality occurrence data is received. On the other hand, when the detailed abnormality occurrence data related to the detailed information is received (Y in step S19), the process proceeds to step S21.

When the processing shifts to step S21, the received detailed abnormality occurrence data is stored in the web server (not shown) in step S21, and the processing shifts to the next processing, that is, the processing of step S23.

When the processing shifts to step S23, in step S23, the received abnormality occurrence data and detailed abnormality occurrence data (in the case of N in step S15, there is no detailed abnormality occurrence data) are automatically analyzed (the CPU is classified as a type). The recovery data instructing the procedure for recovering the thermal device 5 from the cause of the abnormalities thus generated, that is, the data related to the recovery instruction information is generated), and the next process, that is, the process of step S25 is performed.

When the process shifts to step S25, in step S25, the result of the automatic analysis is output to the monitor 13 of the control device 6 or the first control unit 9, and the process shifts to the next process, that is, the process of step S27.

When the processing shifts to step S27, it is determined in step S27 whether or not the maintenance staff 14 needs to be seconded based on the result of the automatic analysis. And
If the maintenance worker 14 is not required to be seconded (N in step S27), the abnormal processing subroutine is terminated and the process returns to the main routine. On the other hand, when the maintenance worker 14 needs to be seconded (Y in step S27), the process proceeds to step S29.

When the processing shifts to step S29, in step S29, the maintenance staff 14 is called to confirm the response, and the processing shifts to the next processing, that is, the processing of step S31. If there is no response from the first maintenance person 14 out of a plurality of registered persons, the second maintenance person 14 is called (if there is no response, the next maintenance person 14 is called and this is repeated until there is a response). , The first maintenance person who got a response
4 is targeted for the next processing.
