Description

An intelligent mouse with heart rate measurement function

technical field

The invention relates to a mouse, in particular to an intelligent mouse with a heart rate measurement function.

Background technique

General mouse on the market only comprises simple mouse function at present. And along with the general use of computer, more and more functions are integrated on the mouse, make the mouse except self operation performance promotion, it also has other more practical functions. For example, the Chinese invention patent application with the application number 201310414315.6 discloses a multifunctional playing mouse, which not only has the function of a mouse, but also has the functions of playing audio and displaying text; A multifunctional mouse with cooling device can not only be used as a mouse to wirelessly operate computers or other electrical appliances, but also has a cooling function; there are other mice with stronger functions or more functions that are not listed here.

However, heart rate, also known as the frequency of heart beating, is an evaluation parameter widely used in medicine to evaluate human health status. Many middle-aged and elderly people with poor heart function or clinical patients need to detect heart rate frequently. In today's society, with the development of the Internet, many young people spend most of their free time on the computer. In severe cases, they surf the Internet all night, or even do not go out for several days, surfing the Internet, working overtime or playing games without restraint. Then there are various news reports of sudden death from playing games, sudden death from staying up late to work overtime, or sudden death while surfing the Internet at home. These disastrous consequences are not only caused by people not knowing how to control and restraint, but also because there is no device that can warn people in time. When surfing the Internet, the mouse is needed, and the device with the heart rate detection function is organically combined with the mouse. When people monitor the abnormal heart rate in the process of operating the mouse on the Internet, they can remind people to take a rest or adjust in time, so as to avoid the occurrence of tragedy.

Contents of the invention

In view of the above-mentioned deficiencies, the technical problem to be solved by the present invention is to provide an intelligent mouse with a heart rate measurement function which not only has the mouse operation function, but also detects the heart rate in real time and can send reminder information.

In order to solve the above problems, the present invention is realized through the following technical solutions:

An intelligent mouse with a heart rate measurement function includes a mouse body and a heart rate measurement module, and the heart rate measurement module includes a sensor module connected in sequence, a DC blocking filter, a two-stage inverting amplifier, a second-order active filter, and a comparison circuit And controller, the output end of described controller is connected with display and buzzer, and described sensor module is installed on the mouse body, is used for collecting the pulse signal of finger, and described display is located at the surface of mouse body; There is a power switch for controlling the opening and closing of the heart rate measurement module.

In the above solution, the controller may be connected with a reset switch, and the reset switch is set on the mouse body.

In the above solution, the sensor module may specifically be an infrared pair tube, mainly composed of an infrared emitting tube and a photosensitive receiving tube.

In the above solution, the second-order active filter may be a low-pass filter.

In the solution above, the comparison circuit includes a single-threshold voltage comparison circuit, and a Schottky diode is connected in parallel to the output terminal of the single-threshold voltage comparison circuit.

The beneficial effects of the present invention are:

The present invention integrates a heart rate measurement module mainly composed of a sensor module, a DC blocking filter, a two-stage inverting amplifier, a second-order active filter, a comparison circuit and a controller on an ordinary mouse, so that people operate the mouse on the Internet. In the process, the finger touches the sensor module, and then collects the pulse signal of the hand touch, and sends it to the controller, which is displayed on the display after being processed by the controller, and an alarm sound is issued when there is an abnormality. The mouse of the present invention not only has the general mouse operation function, but also has the function of detecting the heart rate in real time, and has the characteristics of simple structure and strong practicability.

detailed description

The present invention will be further explained below in conjunction with specific embodiments and drawings, but it is not intended to limit the present invention.

As shown in Figures 1 and 2, a smart mouse with heart rate measurement function includes a mouse body 1 and a heart rate measurement module, and the heart rate measurement module includes a sensor module 5, a DC blocking filter, and a two-stage inverting An amplifier, a second-order active filter, a comparison circuit and a controller. The output of the controller is connected to a display and a buzzer. The mouse body 1 is provided with a power switch 2 for controlling the opening and closing of the heart rate measurement module.

The sensor module 5 is installed on the mouse body 1 for collecting the pulse signal of the finger. In this embodiment, the sensor module 5 is specifically an infrared pair tube, mainly composed of an infrared emitting tube and a photosensitive receiving tube. Of course, other sensors capable of sensing pulses are also possible.

The controller is specifically a single-chip microcomputer, which is used to receive the pulse signal (actually a light pulse signal) sent by the sensor module 5, and calculate and compare the output after processing, display on the display 4 and send a control to the buzzer. Signal. A reset switch 3 is connected to the controller, and the reset switch 3 is arranged on the mouse body 1 .

Described display 4 is arranged on the surface of mouse body 1, specifically can be liquid crystal screen or be made of a plurality of nixie tubes, is used for displaying the result of controller output;

The second-order active filter is a low-pass filter.

The comparison circuit is used to filter side lobe noise to obtain a square wave signal, and specifically includes a single-threshold voltage comparison circuit, and a Schottky diode is connected in parallel at the output end of the single-threshold voltage comparison circuit.

When the invention works:

Because the arteries at the fingertips of the human body are relatively developed, when the arterial blood vessels contract and relax periodically with the heart, the blood volume in the blood vessels will also change. When the mouse body 1 is connected to power through the USB data line 6, press the power switch 2, put your finger on the sensor module 5, the sensor module 5 can collect the corresponding light pulse signal, after denoising, amplification and filtering send it to the controller, and the controller performs calculation and processing to obtain the heart rate data, which is displayed on the display 4; at the same time, the heart rate data is compared with the preset safe heart rate value in the controller, and a control signal is sent to the buzzer, That is, when the detected heart rate is not within the preset safe heart rate value range, it means that the heart rate is abnormal, and the buzzer starts to make a sound to remind people to rest.

The above is only to illustrate the implementation of the present invention, and is not intended to limit the present invention. For those skilled in the art, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be Included within the protection scope of the present invention.
