Problems solved by technology

However, there are still shortcomings and deficiencies in various laser acupuncture instruments at present: the simple irradiation method of certain wavelength laser acupuncture, such as He-Ne laser acupuncture instruments, etc., adopts continuous direct irradiation, which is the simplest working method , the treatment is also the simplest, but it is extremely single in terms of treatment methods and acupuncture techniques, lacks flexibility, and cannot realize the extensive and profound acupuncture theory of traditional Chinese medicine. However, pulsed las...

Embodiment

[0018] figure 1 Disclosed is an embodiment of the present invention, the photodiode (PD) 2 converts the output power of the semiconductor laser (LD) 1 into a proportional current signal, and after the current signal passes through the optical power monitoring circuit 3, it is converted into a proportional The voltage signal is sent to the A / D conversion interface 4 of the MSP430 microcontroller for A / D conversion. The converted digital signal and the given value form a control deviation, and the PID control operation is performed by the single-chip microcomputer 5 to form a control amount. After D / A conversion, the driving current of the semiconductor laser (LD) 1 is controlled. In order to control the laser power, in order to achieve lifting, interpolating and reducing. The increasing rate of optical power is the re-insertion and light-insertion in reinforcing and reducing, and the decreasing rate is the heavy-lifting and light-lifting in reinforcing-reducing; the changing ...

Abstract

The present invention discloses a laser acupuncture therapeutic equipment based on PID control. It is characterized by that the light-sensing diode can be used for converting output power of semiconductor laser into equiproportional current signal, after the current signal is passed through light power monitoring circuit, said current signal is converted into equiproportional voltage signal, then the voltage signal can be transferred into A/D convertor to make A/D conversion; the converted digital signal and specified value are formed into control deviation, a chip computer is used to make PID control operation to form a control quantity; after the digital signal is passed through the D/A convertor, it can be used for controlling drive current of LD so as to control laser power to implement reinforcing and reducing by lifting and thrusting the needle of acupuncture therapy.

Description

technical field [0001] The present invention is a medical instrument invented by combining traditional Chinese medicine acupuncture theory and practice with modern instrument science and technology. It uses MSP430 single-chip microcomputer as the control platform, integrates classic PID control theory into laser diode power control, and introduces chaos mathematical model method to realize Realize the simulation of new dynamic, deep and easy-to-control moxibustion methods, and can realize the most basic acupuncture-reinforcing and reducing techniques in traditional Chinese medicine and the semiconductor laser acupuncture-moxibustion therapeutic instrument. Background technique [0002] The research and development of modern acupuncture and moxibustion treatment instruments have gradually embarked on the road of development and integration of modern science and technology, especially on the basis of traditional Chinese medicine theory, combined with computers, microelectronics...
