Abstract

The invention relates to the technical field of an instrument, in particular to a master control system of a transient electromagnetic detecting instrument and a use method of the master control system. The master control system comprises a receiving conversion module, a central processing module, a storage module and a final data transmission module; the receiving conversion module is used for converting an analogue signal, transmitted from the outside, into a digital signal; the central processing module can be a complex programmable logic device (CPLD) and can be used for storing the digital signal and storing the digital signal in the storage module; the storage module is used for storing the digital signal acquired by the central processing module; the final data transmission module is used for acquiring the digital signal transiently stored in the central processing module, converting the digital signal into the format capable of being received by an upper computer, and then transmitting the digital signal to the upper computer. According to the master control system of the transient electromagnetic detecting instrument provided by the invention, the data acquisition speed of the master control system is not reduced remarkably when functional units are added to the master control system.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a main control system of a transient electromagnetic detector and a use method thereof. Background technique [0002] The transient electromagnetic detector uses the principle of transient electromagnetic to carry out geological detection and other applications, including the transmitting system, the amplifier system and the receiving and collecting system. The receiving and collecting system has a main control system. The receiving and collecting system of the commonly used transient electromagnetic detector mainly uses Single-chip microcomputer as the main control system. When using the main control system of the existing transient electromagnetic detector, a detection signal is first transmitted to the detection object through the transmission system, and a new magnetic field will be generated after encountering a specific medium, and a new magnetic field will b...
