The I-node instrument has two acquisition modes in field construction: the method comprises the steps of collecting a built-in detector and collecting an external detector. When the external detector acquisition mode is adopted, the node instrument and the detector string are connected by the switching cable, then the node instrument is started for self-checking, and blind acquisition is started after the self-checking is normal, namely, the uninterrupted acquisition mode without remote monitoring is adopted. When the line inspection personnel inspect, even if the detector has faults, such as failure, short circuit or poor contact with the node instrument, the detector resistance value displayed on the handbook is still the detector resistance value just after the hand book is started, and the false image that the fault detector still works still occurs. If the real-time resistance of the detector string is to be displayed by the handbook, the node instrument must be restarted after being shut down, and the current resistance of the detector string can be displayed by the handbook. The node instrument generally needs to continuously work for about 5 days in the field to recover and download the seismic data, and does not have special conditions and does not need to be started or shut down during the working period. Therefore, the state of the detector string cannot be detected in real time, if the detector string is found to be not subjected to data acquisition due to the detector failure or connection failure during recovery, the seismic data on the physical point where the detector string is located cannot be subjected to gun supplementing acquisition, so that a channel is caused, geological data is affected, and loss is irreversible.
