Abstract
This paper describes the design of digital type pulsimeter for the body. With the development of modern science and technology, testing demand has been becoming higher and higher. The traditional human body pulsimeter takes one minute to test .As a result; it wastes the time of testing and affects the accuracy. In order to improve the technology of testing, this paper offers an effective method.
This design is based on the angle designed in digitization and describes the principle of the pulsimeter. It consists of the phase-locked loop 100 frequency multiplication .Thus it realizes that we can demonstrate body’s true pulse number in 1 minute by reading 2 times human body pulses signal number. So this instrument testing reduces the time of testing. As well, the design which uses three dynamic scanning to count/display makes it very convenient for the user to read the pulse number. And it improves the accuracy. The design also uses the integrated circuit design leading to the lower spend, lower power loss, and strong antijamming ability. So it is suitable for such fields as the hospital and stadium est. So it has high commoditized value.
Keywords: Pulse number, Phased-locked loop 100 frequency multiplication, Count/display.
