Multi-frequency induced polarization instrument receiver and ground potential difference response signal processing method

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.
