Automatic inspection and monitoring method based on time domain slotting control

An automatic inspection and monitoring method based on time domain slotting control, characterized by comprising:

• a method of extraction and transmission of a seismic apparatus host on the information of a field device, a method of reception and management of a field monitor on the information of a field device, an encoding protocol of information push and a time domain slotting control, wherein
• the method of extraction and transmission of a seismic apparatus host on the information of a field device is implemented by a master control program comprising:
• automatically extracting and classifying test information about the seismic apparatus host on the field device from the seismic apparatus host, and conducting a protocol encoding according to a designed encoding protocol of information push;
• automatically generating a data frame block;
• and then delivering the information via a broadcasting station;
• the encoding protocol of information push is designed for avoiding information loss caused by signal instability, etc. during information push;
• encoding the test information on the field device according to the encoding protocol of information push, to generate a data frame block, so that the signals are effectively retrieved or retransmitted when the signals are lost, thereby ensuring information integrity;
• the encoding protocol of information push mainly includes a channel data protocol, a voltage value protocol, a range value protocol, an inquiry request protocol and an instant dialog protocol;
• according to the encoding protocol of information push, encoding the information on the field device of the seismic apparatus host to generate a data frame block in a fixed format upon extraction and transmission;
• and then pushing the information in such format;
• conducting parsing also according to the encoding protocol of information push while the monitor receives this data frame block, so as to obtain state information on the field device;
• the data frame block referring to state information on the field device of the seismic apparatus, and being encoded through the encoding protocol of information push, where each field device automatically generates one data frame block, since status information on the field device differs and the produced data frame block is different in size, each data frame block has a CRC redundancy checking function;
• the master control program being installed onto the seismic apparatus host or other computers connected with the seismic apparatus host for implementing extraction and classification of information on the field device of the seismic apparatus host, and automatically generating a data frame block by using the encoding protocol of information push, and controlling a station to transmit the state of the field device of the seismic apparatus to the field inspection and monitoring program by using the time domain slotting method;
• the method of reception and management of information about the field monitor on the field device being implemented by monitoring programs, comprising:
• parsing the received data frame blocks according to the protocol format, storing and managing the field device status data obtained by parsing according to setup requirements, thereby realizing the field personnel's automatic inspection and management of the seismic apparatus and device;
• the monitoring program being installed onto a hand-held intelligent transceiving tablet computer or other device supporting a co-band transceiving function compatible with the system for implementing a reception of the data frame block of the master control program by using the time domain slotting method, and automatically parsing the data frame block by applying the encoding protocol of information push for obtaining the state information on the field device of the seismic apparatus, and managing the state information according to the setup requirements;
• the time domain slotting control being designed for avoiding signal loss caused by signal collisions of a field monitor, comprising:
• allowing each terminal device to transmit information by a time-share according to the time domain slotting control mode to ensure that a signal is stable;
• the time domain slotting control comprising five kinds of control modes such as a conventional time slot control, a repetition unit control, an intelligence decision control, a repetition master transmission control and an inquiry transceiving control, one of which is selected based on different requirements for operation after the information on the field device of the seismic apparatus host is extracted.
