Cableless storage seismograph low power consumption power management system and management method

Abstract

The invention relates to a low-power-consumption power supply management system and a low-power-consumption power supply management method for a cable-less storage type seismograph. A pre-mounted low-power-consumption power supply management module in a collection station is that a power supply is connected with a singlechip microcomputer, a beidou module, a collection unit and a GPS (global positioning system) positioning unit respectively through a switch circuit; the singlechip microcomputer is connected with a GPRS (general package radio service) module and a main control unit respectively through an analog switch; the beidou module is connected with the singlechip microcomputer and the main control unit respectively through the analog switch; the main control unit is connected with the collection unit and the GPS positioning unit respectively; the power supply is formed by connecting a voltage conversion circuit with the singlechip microcomputer. According to the power supply management method, the cable-less seismograph is controlled by a handheld terminal, a network server or a beidou upper computer; the environmental limitation to outdoor work is lower, and remote control is randomly executed, so that one-to-multiple control is realized; a plurality of seismographs can be controlled to enter a low-power-consumption mode or a normal working mode through the handheld terminal, the network server or the beidou upper computer, and the low-power-consumption control on more seismographs within a large-area region is achieved.

Description

[0001] Technical field: [0002] The present invention relates to a geophysical prospecting power management system and management method, in particular to a low-power consumption power management module and management method of a cable-free storage seismograph, especially a GSM, GPRS and Beidou-based module suitable for long-time work in the field. A low-power consumption power management method for remote cable-free storage seismographs and other communication technologies. [0003] Background technique: [0004] Seismic exploration is an important method in geophysical exploration. As a data acquisition system in seismic exploration, seismographs are widely used in underground resource exploration such as oil and gas resources, metal mines, etc., and engineering applications such as logging systems. Currently there are three main types of seismographs: wired telemetry seismographs, cable-free storage seismographs and wireless telemetry seismographs. Among them, the wired te...

Problems solved by technology

When conducting field acquisition experiments, it is often necessary to arrange a large number of cable-free storage seismograph acquisition stations in a large area, and it is unrealistic to reduce the power consumption of the acquisition stations by manually controlling the seismometers one by one. Therefore, it is necessary to introduce a method of remotely controlling the seismograph to achieve low power consumption

[0007] Yang Hongyuan and others published "Low Power Consumption Design of Cableless Telemetry Seismograph Acquisition Station" in "Electrical Measurement and Instrumentation" 2009 Issue 01, Volume 46, Issue 517. In this paper, low power consumption components were selected for hardware circuit design and Optimize the software design to reduce the power consumption of the seismograph collection station. ARM is used as the main control center for dynamic power management. Although it can reduce the power consumption of the seismograph collection station to a certain extent, the power consumption of the ARM is much greater than that of the MSP430 microcontroller. Power consumption; this design does not use remote communication to achieve low power consumption of the seismograph collection station. When hundreds of seismographs work in a large area in the field, their practicability is bound to be limited to a certain extent
