Embodiment Construction
[0029] As shown in the figure, the wired, wireless and cableless three-in-one digital seismograph of the present invention is more precisely a new type of digital seismograph system with wired telemetry, wireless telemetry and cableless "three-in-one". Three types of instruments, namely, the wireless telemetry digital seismograph and the cableless digital seismograph, have been optimized and combined. The biggest feature of this system is to make full use of the advantages of wired telemetry, wireless telemetry and cable-free, making the new digital seismograph system suitable for various complex surfaces and terrains, and achieving the best optimization of seismic exploration construction scheme and cost. The system can be divided into four parts ( figure 1 ): Central Control Operating System (Instrument Vehicle) CCOS, Wired Telemetry Acquisition Station AS (Acquisition Station), Wireless Telemetry Acquisition Station WAS (Wireless Acquisition Station) and Cable-less Acquisit...

The invention relates to a digital seismic instrument with integration of wired, wireless and cable-less modes into one, so that a problem that an existing seismic instrument is not suitable for various complex surfaces and landforms can be solved. On the basis of optimization and combination of a wired telemetering digital seismic instrument, a wireless telemetering digital seismic instrument and a cable-less digital seismic instrument, the digital seismic instrument is divided into four parts: a central control operation system (CCOS), a wired telemetering acquisition station (AS), a wireless acquisition station (WAS), a cable-less acquisition station (CAS). The CCOS is respectively connected with a wireless communication root unit (RU), a wireless root unit (WRU), a cable-less data unit (CDU) by network cables; the wireless communication root unit is utilized to control and connect the wired telemetering acquisition station; the WRU is utilized to control and connect the WAS; and the CDU is utilized to recover data of the CAS. According to the invention, advantages of a wired telemetering mode, a wireless telemetering mode and a cable-less mode are fully utilized; the digital seismic instrument can be applied to various complex surfaces and landforms; and optimal optimization of a construction scheme and cost of earthquake exploration and measurement can be realized.
Description
technical field [0001] The invention relates to a seismograph, in particular to a wired, wireless and cableless three-in-one digital seismograph. technical background [0002] High-precision digital seismograph is a geological exploration instrument used to record artificial or natural seismic signals, and then to find oil, gas, coal and other mineral resources based on the records of these seismic signals, and can be used to detect the internal structure of the earth, conduct engineering and geological Disaster prediction, etc. [0003] Seismic exploration method is still the main means of oil and gas exploration on land and sea, and also an important exploration method for other mineral resources, and is widely used in the study of the earth's internal structure, engineering exploration and detection, geological disaster prediction and so on. [0004] Digital seismographs for geophysical exploration of mineral resources can be divided into three categories according to da...
