  • Automatic inspection and monitoring method based on time domain slotting control
    Patent number: 10409251
    Abstract: An automatic inspection and monitoring method based on time domain slotting control, belonging to the technical field where the field personnel can automatically inspect and monitor a field device of a seismic apparatus in the seismic exploration production. A method of extraction and transmission of a seismic apparatus host on the information of a field device is implemented by a master control program, test information about the seismic apparatus host on the field device can be automatically extracted and classified from the seismic apparatus host, and according to a designed push protocol, a protocol encoding is conducted; a data frame block is automatically generated; and then the information is delivered via a broadcasting station; an encoding protocol of information push is designed for avoiding information loss caused by signal instability, etc. during information push. According to the protocol, the state information on the field device is encoded to generate a data frame block.
