    However, in the conventional data acquisition system, since a large amount of environmental test data is concentrated by one sub system, when an abnormality occurs in the sub system, all the environmental test data that has been processed is deleted and cannot be recovered. In addition, even if data was backed up to the backup device, there was a problem that only some of the environmental test data could be recovered.
    Another problem is that since a large amount of environmental test data is concentrated by one subsystem, the amount of environmental test data processed by one subsystem is too large, resulting in a slow data throughput due to system load. .

    In this case, the plurality of sub-systems 200 are connected one-to-one with the plurality of filters 101 mounted in the filter unit 100, respectively, and each process only a predetermined number of the total channels that the data acquisition system can process. It is composed of parallel distributed structure.
    Therefore, even if an abnormality occurs in one subsystem 200 among the plurality of subsystems 200, the environmental test data processed by the other subsystem 200 is not deleted but is preserved.
    Meanwhile, the plurality of subsystems 200 respectively receive environmental test data output from the corresponding filter 101 connected to the plurality of filters 101, and store the same in the corresponding memory. The data is backed up to 300, and the environmental test data is converted into environmental test data for display and then output to the mast computer 400.
