Embodiment Construction

[0021] See figure 1 , land geophysical prospecting data acquisition station, including interconnected field programmable gate array 1 and analog circuit unit 2, analog power supply 3 connected with analog circuit unit 2, interface unit connected with field programmable gate array 1 , and a digital power supply module 6 connected to the field programmable gate array 1 and the interface unit respectively;

[0022] See figure 2 , an adaptive low-power consumption method suitable for onshore geophysical exploration data acquisition stations, specifically including the following steps:

[0023] (1) After the collection station is powered on, it is initialized. The initialization mainly completes the numbering of each collection station, making preparations for the next frame upload, and avoiding confusion when the software performs data reorganization (time sequence transfer sequence); after initialization , waiting for the self-inspection test command, the self-inspection test ...

Abstract

The invention discloses a self-adaptive low-power consumption method suitable for an overland geophysical exploration data acquisition station. When the acquisition station is in an idle mode, an analog power supply is controlled to stop supplying power to an analog circuit, and the analog circuit stops working, so that the acquisition station enters a low-energy consumption working mode to reduce the power consumption of the acquisition station; and therefore, the power consumption of an overall seismic prospecting instrument is reduced, the service life of a system power supply and the system standby time are prolonged, batteries are prevented from being replaced frequently, and the efficiency of field construction is improved.

Description

[0001] technical field [0002] The invention relates to a seismic data acquisition and transmission system, in particular to an adaptive low power consumption method suitable for land geophysical exploration data acquisition stations. Background technique [0003] For large-scale land seismic exploration systems, power consumption is an important issue, which not only directly determines the continuous working time of the system, but also partly determines the power supply mode that the system needs to adopt. As the acquisition station with the largest number in the onshore seismic exploration system, its power consumption level determines the power consumption level of the entire exploration system. At present, the most advanced land seismic exploration instrument data acquisition system at home and abroad is the 428 series land seismic data acquisition system of the French company Sercel, the CNPC ES109 10,000-channel land seismograph system, etc. [0004] The French Ser...
