The invention relates to a remote monitoring system and method of a cable-free seismic detector and a field working method. The upper computer of the ground control center communicates with the seismic detector at a farther node through UART, a Beidou commanding machine and a Beidou satellite, and the seismic detector at the farther node and a collecting station form a wireless network through WiFi. Compared with the prior art, the remote monitoring system and method and the field working method have the advantages that the respective limitations of Beidou communication and WiFi communication on seismic detector remote monitoring are broken through by a Beidou communication plus networking transmission mode, effective monitoring of the seismic detector under a depopulated zone environment is achieved actually, and state information inquiring, working state controlling and parameter configuring are achieved; workers can timely discover and process sudden problems during exploration, the collecting station can collect real seismic data, work efficiency of field seismic exploration experiments is increased, and field work cost is lowered.

Description

technical field [0001] The invention relates to a remote monitoring system and monitoring method for a cableless seismograph in the field, in particular to a low-cost remote monitoring system for a cableless seismograph based on the combination of Beidou communication and wireless networking, a monitoring method and a field working method. Background technique [0002] Seismograph is an important part of seismic exploration, mainly to complete the acquisition and recording of seismic data. With the increase in demand for resource exploration and seismic exploration accuracy, the number of acquisition channels of seismographs increases, and the arrangement and wiring of cable seismographs in the field environment, as well as the management and maintenance of cables, are very difficult and require a lot of manpower and cost. It is difficult to meet the trend that seismic exploration is gradually developing in complex environments. Therefore, the cableless seismograph has been...

Problems solved by technology

[0010] CN104020746A discloses a "method for remote quality monitoring of cable-free seismographs using Beidou communication satellites", which solves the problem of remote monitoring of cable-free seismographs in field environments to a certain extent. All the stations are connected to the Beidou user machine module. Because the cost of the Beidou module is relatively high, this will greatly increase the cost of the seismograph, which in turn will limit the wide application of the cable-free seismograph.

In addition, due to the limitation of Beidou communication bandwidth, most of the current Beidou command machines can only manage 100 / 200 basic sub-users in real time, which is far from enough in actual field seismic exploration

Therefore, the cost and quantity limitations of the Beidou communication system make the remote monitoring of cable-free seismographs using Beidou communication only suitable for seismic experiments with a small number of seismographs, and cannot be popularized and used in large-scale field exploration experiments.
