Problems solved by technology

Its disadvantages are: 1. The data in transmission needs to be modulated and demodulated, and the efficiency is low; 2. Due to the overlapping of the original transmission network or line, the current fluctuation of the monitoring equipment is likely to interfere with the FSK data transmission in real time

Abstract

The invention relates to the technical field of FSK data monitoring, in particular to FSK data monitoring equipment based on an FPGA. The equipment comprises a plurality of acquisition modules, a control optical coupling isolation module, a control magnetic coupling isolation module and a main control chip, the acquisition modules are connected with a serial port control end of the main control chip through the control optical coupling isolation module and the control magnetic coupling isolation module, and the main control chip is further connected with an Ethernet, an LCD, keys, a USB port and a TF port. The optical coupler uses optical signals as media to achieve coupling and transmission of electric signals, input and output are electrically and completely isolated, and the equipment has the advantage of being high in anti-interference performance.

Description

technical field [0001] The invention relates to the technical field of FSK data monitoring, in particular to FPGA-based FSK data monitoring equipment. Background technique [0002] FSK (Frequency-shift keying) is an earlier modulation method used in information transmission. It has been widely used in data transmission of transportation systems such as subways. Existing monitoring equipment usually directly reads the data content in transmission for analysis, so as to distinguish whether the FSK data transmission is normal. Its disadvantages are: 1. It needs to modulate and demodulate the data in transmission, and the efficiency is low; 2. Due to the overlapping of the original transmission network or line, the current fluctuation of the monitoring equipment is likely to interfere with the FSK data transmission in real time. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an FSK data monitoring device. [00...
