Abstract

The invention provides a novel signal detection and acquisition device which comprises a signal detection and acquisition unit and a management control unit which are in communication connection witheach other for data transmission, the management control unit is in communication connection with an upper computer so as to receive control command information sent by the upper computer and furthersend the control command information to the signal detection and acquisition unit, and the signal detection and acquisition unit performs signal detection and data acquisition according to the controlcommand information, and sends the acquired data information to the management control unit so as to send the acquired data information to an upper computer. An STM32 chip and FPGA chip architecturedesign is adopted, data transmission is carried out in a data bus mode, various types of data in the FPGA chip are transmitted to the STM32 chip through an FSMC interface, and then the STM32 chip drives an internet access to realize data transmission with an upper computer, so that original data acquired by detection is locally stored; and the transmission stability after signal detection and acquisition is ensured, and high-speed transmission of data is realized.

Description

technical field [0001] The invention belongs to the technical field of signal detection, and in particular relates to a novel signal detection and collection device capable of realizing high-speed data transmission and significantly improving the efficiency of data detection and collection. Background technique [0002] Very low frequency detection is to receive and monitor lightning radiation in nature and extremely low frequency (ELF: 300Hz-3kHz) and very low frequency (VLF: 3-30kHz) wireless electromagnetic wave signals emitted by ground-based stations all over the world. At present, it is widely used in the fields of solar activity monitoring, ionospheric detection and marine communication. [0003] Traditional signal detection equipment often uses FPGA as the core device of system control, and then combines with USB chip to realize the transmission of various data on FPGA. However, the USB communication method will be unstable when transmitting data, which will easily ...
