Referring back to FIG. 3 , the data storage unit 50 is provided to store ambulance driving information, abnormal state analysis information, and data input to the ambulance. Through the data stored in the data storage unit 50, the abnormal state can be analyzed and the cause of the problem occurring in the operating equipment can be derived. The data storage unit 50 includes a driving history storage module 51 and an analysis storage module 53, and may additionally store image information and road information including a camera module as data input to the ambulance.

The driving history storage module 51 is provided to store the driving time, driving speed, and location of the ambulance according to time. As in the embodiment of the present invention shown in FIG. 10 , the driving history storage module may store the driving history of the ambulance, and the data stored by the ambulance driving is the driving time of the vehicle, the driving speed, and the vehicle according to the time. location, etc. Such data may be loaded from the matching module 45 and matched with the data on the current pattern of the operating equipment. The driving history storage module 51 may be provided as an ESM.

The analysis storage module 53 is provided to store the current pattern of the operating equipment and the abnormal state according to the current pattern. The operating time of the operating equipment, the current pattern according to the operating time, and the abnormal state can be stored, and it is matched with the driving history of the vehicle so that the above-described matching module 45 can derive the cause of a problem in the operating equipment. The analysis storage module 53 may be provided as an ESM.

Referring back to FIG. 3 , the ambulance system 1 capable of self-diagnosis may further include a gateway transmission unit 60 . The gateway transmitter 60 may transmit the driving history of the ambulance when connected from the outside, driving information stored in the data storage unit 50 , and information on an abnormal state obtained by analyzing a current pattern. When the self-diagnostic ambulance system 1 is to be monitored or diagnosed from the outside, the system and external equipment are connected by the gateway, so that the log can be read and the abnormal state can be analyzed.

The above detailed description is illustrative of the present invention. In addition, the above description shows and describes preferred embodiments of the present invention, and the present invention can be used in various other combinations, modifications, and environments. That is, changes or modifications are possible within the scope of the concept of the invention disclosed herein, the scope equivalent to the written disclosure, and/or within the scope of skill or knowledge in the art. The written embodiment describes the best state for implementing the technical idea of the present invention, and various changes required in specific application fields and uses of the present invention are possible. Accordingly, the detailed description of the present invention is not intended to limit the present invention to the disclosed embodiments. Also, the appended claims should be construed to include other embodiments.
