Design of intermediate frequency electrotherapy apparatus based on CPLD

摘要

Aiming at the disadvantages of the electrotherapy apparatus in the market such as complex hardware design and single function, a way based on CPLD is adopted to devise intermediate frequency electrotherapy apparatus, which implements the occurrence of treating wave and the digital adjusting for treating frequency, pulse-width and amplitude, the system is under the control of single chip microcomputer. For the use of CPLD, circuit is simplified, expansibility is enhanced and the function is programmable, it can produce various single treating waves and wave combination, can provide the relevant therapeutic scheme for different patients, and meanwhile it provide an effective test platform for the treatment of biological research, After testing, the output of treating wave is accurate and reliable, can meet the performance requirements well.
