Problems solved by technology

However, due to the use of analog detection methods in many electrical geophysical instrument receivers, the volume and quality of the entire instrument will increase, the cost will increase, the confidentiality will decrease, and the field construction will become more difficult. Moreover, affected by the analog devices, the overall There are also certain deficiencies in the temperature effect, accuracy, consistency, anti-interference ability and other aspects of the machine; not only that, the frequency type and function of these electrical instrument receivers are single, which makes their resolution for mines and non-mines low. , the flexibility to choose different functions in different working environments is low

Abstract

The invention discloses a multi-frequency induced polarization instrument receiver and a ground potential difference response signal processing method. The multi-frequency induced polarization instrument receiver comprises a GPS (global positioning system) module, a liquid crystal screen, an input module, a pre-mounted conditioning module, an acquisition buffer module, a slave controller, a first power source, a main controller, a liquid crystal screen driving module, a communication module, a storage module and a second power source module, wherein the pre-mounted conditioning module, the acquisition buffer module, the slave controller and the first power source module are integrated on a slave control panel, and the main controller, the liquid crystal screen driving module, the communication module, the storage module and the power source module are integrated on a main control panel. The multi-frequency induced polarization instrument receiver is small in size, light in weight and high in confidentiality, so that field construction is more convenient and easier, performance of the like instruments is improved, multiple frequency types can be provided, and mineral substance resolution ratio of the instrument is increased and using flexibility of the instruments is improved.

Description

technical field [0001] The present invention relates to an electrical geophysical prospecting instrument and its signal processing method, in particular to a multi-frequency IP instrument receiver and its earth potential difference response signal processing method. Background technique [0002] At present, known geophysical instruments are mainly based on four methods: electric method, magnetic method, gravity method and seismic method. Electric and magnetic methods are mostly used in the exploration of solid minerals, and seismic methods are mostly used in oil exploration. Electrical prospecting is a method of supplying direct current to the ground through two (or more) power supply electrodes, measuring the potential difference response of the earth through two direct current electrodes, and calculating parameters such as apparent resistivity and phase shift. However, due to the use of analog detection methods in many electrical geophysical instrument receivers, the volu...
