One embodiment of the application " is although it is possible to refer to identical embodiment, but is not necessarily referring to identical embodiment.
For the sake of simplicity, eliminate in below describing and well known to a person skilled in the art some technical characteristic.
An embodiment according to the application, provides a kind of low pulse physiotherapy instrument, as it is shown in figure 1, include MCU processor,
Power amplification circuit, increasing apparatus, piezoelectric driving circuit and control panel;MCU processor is put with waveform recombiner, power respectively
Big circuit, increasing apparatus, piezoelectric driving circuit and control panel electrical connection.
MCU processor, is responsible for producing various composite wave-shapes required for physiotherapy equipment output, and basic waveform includes the triangle of symmetry
Waveform, sinusoidal wave, square wave and DC component are the trapezoidal wave of zero, and composite wave-shape is then to be generated by above waveform combination, with necessarily
Cycle exports.Composite wave-shape comprises continuous wave, density waveform, interrupted waveform.In the present embodiment, MCU processor is 32, master
Frequently the processor of 48MHz, built-in 64Kbytes flash memory, 16 port number weighted-voltage D/A converters, 10 groups of timers, DLT is used
Input/output port, the PWM waveform of the highest generation 3MHz, therefore apply low frequency K Hz waveform to have at a relatively high accuracy.
Power amplification circuit, for realizing being amplified by analog circuit by the composite wave-shape that MCU produces, MCU produces
Composite wave-shape energy small, it is impossible to directly export, it is therefore desirable to through overvoltage, Current amplifier, make this composite signal have one
