Problems solved by technology

In order to solve the search problem of the cableless self-positioning seismograph, during the field construction, the staff often use the handheld GPS device to search the cableless self-positioning seismograph in combination with the pre-recorded GPS position information of the cableless self-positioning seismograph. , limited by the accuracy and stability of GPS, the accuracy and efficiency of this search method is low, especially in complex geological terrain conditions, such as plateau environments, even if accurate GPS coordinates have been recorded, it is difficult to find earthquakes with handheld GPS devices The exact location of the buried seismograph is still easy to cause the loss of the seismograph

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the invention is described in further detail:

[0017] figure 1 It is a schematic diagram of cable-free self-positioning seismograph communication. The seismograph uses its own WIFI module to independently establish a wireless network (the circle in the figure indicates the coverage of the seismograph network). When multiple seismographs are within the coverage of each other's network, multiple seismographs Share a network (area A and area C in the figure); when a single seismometer and its adjacent seismometers are not within the coverage of each other's network, the seismometer forms its own network (area B in the figure). Use a portable tablet computer or smart phone as a terminal device. When the terminal device is within the coverage of the seismograph network, the terminal device will automatically join the seismograph network and communicate with the seismograph in the network (terminal device A in the...

Abstract

The invention relates to a method for automatically searching for an untethered self-positioning seismograph. According to the method, a wireless communication network is built by using a built-in WIFI module of the untethered self-positioning seismograph, and the purpose of automatically searching for the untethered self-positioning seismograph is achieved by searching for the seismograph network and real-time monitoring the change of the seismograph. With the method, the problem of difficult searching for the untethered self-positioning seismograph under complicated geological conditions is solved, and the purpose of automatically searching for the untethered self-positioning seismograph is achieved; the method is used conveniently and operated simply, and can help workers accurately, rapidly position the untethered self-positioning seismograph, thereby avoiding the loss of the instrument.

Description

Technical field: [0001] The invention relates to a field automatic search method for a geophysical detection device, in particular to a field automatic search method for a cable-free self-positioning seismograph. Background technique: [0002] At present, seismic exploration is gradually developing towards complex geological conditions and exploration environments. The increasing difficulty of exploration and the extension of exploration fields, as well as the continuous development of seismic exploration acquisition theory and new methods, put forward higher requirements for the performance of seismic instruments. The cableless self-positioning seismograph has excellent acquisition characteristics such as low noise, low distortion, wide-frequency response, and large dynamic range, and can realize the acquisition of rich geological information; at the same time, the cableless self-positioning seismograph can realize all field The spatial three-dimensional position measuremen...
