Electronic measurement method and multifunctional electronic measuring instrument

Abstract

The invention discloses an electronic measurement method, which comprises multiple electronic measurement functions, and also comprises that: a hardware platform consisting of DSP and FPGA development modules, a software platform consisting of muclinux and GUI development modules, and a system power supply supplying power for hardware modules are set; analog signals are input from an analog front end, converted into digital signals by a sampling module, processed by an FPGA internal cache and sent to a DSP for operation processing, and finally a result is transmitted to a TFT LCD display for display and output; the DSP calls signals generated by a signal generating module in an FPGA and calls out the digital semaphore to a signal output module, and the signals are output after smooth filtering by an analog back end; a muclinux operating system is utilized to be responsible for monitoring human-computer interfaces, and executes corresponding function tasks according to user instructions; and the muclinux operating system calls corresponding hardware module drivers according to different tasks so as to realize required functions through the hardware modules.
