Detailed ways

Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:

An intelligent finger-type pulse detector, as shown in Figure 1 and Figure 2, is composed of a casing 1 and its internal control circuit, and the casing is provided with a computer interface 2, a liquid crystal display 3, operation buttons 4, signal The pick-up area 5, the power interface 6 and the power switch 7, the control circuit includes a single-chip microcomputer, a power circuit, a button circuit, a pulse signal detection and conditioning circuit, a memory, a display module, an audible and visual alarm module, a short message module, a USB interface module, a power circuit and The single-chip microcomputer is connected to supply power for the control circuit, and the single-chip microcomputer is respectively connected with the button circuit, pulse signal detection and conditioning circuit, memory, display module, sound and light alarm module, SMS module, and USB interface module through the I/O interface. The signal detection and conditioning circuit, the display module and the USB interface module are respectively connected with the operation keys on the casing, the signal pick-up area, the liquid crystal display screen and the computer interface. The power supply circuit adopts a linear DC power supply circuit with low power consumption and high stability, which can convert the power supply to a stable DC power supply for the control circuit. The external AC power supply is connected to the power circuit through the power interface on the casing. The various parts of the control circuit are described below:

The button circuit is connected with the operation button to detect whether there is an operation button pressed and input to the single-chip microcomputer. The operation buttons include a reset button, an image storage button, a mute button, an image call button and a delete button. Among them, the reset key is used to reset the single chip microcomputer and start a new detection, the image storage key is used to store the pulse image displayed on the current display screen, the mute key is used to cancel the sound alarm, and the call image key is used to save the image in the memory Take it out and display it on the display screen, and the delete key is used to delete the stored image.

The pulse signal detection and conditioning circuit is composed of a photoelectric pulse sensor, a signal amplifier circuit, a low-pass filter circuit, and an AD conversion circuit. connect. The pulse signal detection and conditioning circuit uses a photoelectric pulse sensor to collect pulse information, and the collected signal passes through the signal amplifier circuit and the low-pass filter circuit to remove power frequency noise interference, and the obtained analog signal is converted into a digital signal by A/D and sent to the microcontroller , the single-chip microcomputer analyzes and processes the pulse digital signal collected in real time and displays the processing result in the form of an image through the display screen.
