Wireless transmission type digital oscillograph device

Abstract

The invention provides a wireless transmission type digital oscillograph device. The device comprises a frequency meter module, a multimeter module, an oscillograph module, an embedded CPU module and a wireless transmission module; a radio frequency front end circuit comprises a voltage doubling circuit, a voltage stabilizing circuit, a restoring circuit, a clock circuit, a modulating circuit and a demodulating circuit; the radio frequency front end circuit is used for generating power, clock, data and restoring signals for a digital baseband circuit; the digital baseband circuit comprises a data synchronizing module, a data decoding module, a main control module, a data storing module, a data decoding module and a clock generating module; the digital baseband circuit is used for performing instruction analysis for the demodulated data, encoding the data according to the instruction, and modulating an antenna; data signals to be sent are sent through the modulating circuit of the radio frequency front end circuit by the digital basement circuit. According to the wireless transmission type digital oscillograph device, the radio frequency signals are coupled through a magnetic field or transmitted through electromagnetic wave, so as to achieve noncontact information transmission; the frequency reaches the microwave band, so that the interference resistance is improved, and the transmission distance is increased.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a digital oscilloscope device. Background technique [0002] Digital oscilloscopes are generally used for on-site testing and maintenance services. When testing or maintenance personnel diagnose equipment faults on site, they often need to save the test data and analyze and compare the data to quickly locate the fault. However, this method of on-site testing requires professional testing or maintenance personnel to conduct on-site equipment, and the efficiency of fault diagnosis is closely related to the ability of testing or maintenance personnel, so the efficiency is relatively low. [0003] Domestic existing digital oscilloscopes generally support data storage and wired transmission functions. The equipment testers save the test data on site, and then transmit the test results to the remote computer by cable for use by professional testers or maintenance personnel, and can ev...
