1、 Preface

Heart rate, this word should be familiar to everyone. Even though it is not often heard before, wearable intelligent devices seem to have become an indispensable thing with the popularity of wearable intelligent devices in recent years.

Heart rate refers to the beating frequency of the heart and the number of beats of the heart per minute. In addition, there is another rhythm, which refers to the rhythm of the heart beating. It cannot be confused with the heart rate. For example, arrhythmia. It's not an irregular heart rate.

As the saying goes, "Don't be depressed. Life is like an electrocardiogram. If everything goes smoothly, you will be dead."

As the living standard is getting higher and higher, people should pay more attention to their own health. Know yourself, starting with your heart rate.

Xunzhi H1 ECG Band is a product that can accurately monitor and obtain the heart rate, sense the heart risk and avoid sports injury.

thank Love to play computer games And ODM Technology for trial use.

2、 Hardware

The product packaging is in order, the combination of background color and line is very scientific, and the main picture of ECG belt is in a prominent position in the middle.

The back is the main product specifications. Waterproof grade IPX7.

The method name of IPX7 is short-time immersion test. Test equipment and test conditions: immersion tank. The size shall be such that the distance from the bottom of the sample to the water surface is at least 1 m after the sample is put into the immersion tank. The distance from the top of the sample to the water surface shall be at least 0.15 m. Test time: 30 min。

This means that ordinary rain and sweating will never hurt H1. Long time swimming and diving will not work.

The outer skin is an empty sleeve on both sides.

Open the cover of the inner box, the heart rate tape host, the charging base, and the tape.

All items.

The ECG host and charging base are combined by magnetic attraction.

A snap fastener is arranged between the main body of the ECG belt and the webbing.

The combination direction must be correct, and the font must face upward.

The material of the webbing is very soft, and the length can be adjusted in a large range. Of course, it's better to clean the fabric after movement, or it will be full of sweat when you use it next time.

There is a special small nodule on the right atrium of the human body, which is composed of special cells and is called the sinoatrial node. It can automatically and rhythmically generate electric current, which is transmitted to all parts of the heart in the order of conducting tissue, thus causing the contraction and relaxation of myocardial cells. The normal heartbeat of the human body comes from here, which is the "cardiac pacemaker". Every time a sinus node impulse occurs, the heart beats once, which is called "sinus rhythm" in medicine.

Therefore, the normal beating of the heart should be sinus rhythm. If you want to detect it, you must be able to conduct electricity. Therefore, there are generally conductive areas on the heart rate belt. Before wearing it, it is generally necessary to smear some water to facilitate conductivity.

There is a small problem here. The main body of the ECG belt and the webbing are buckled too tightly. Although it ensures that the main body is not easy to fall off, it needs a lot of force to remove it. Of course, it may be that I didn't find the correct method, which may damage the webbing. The metal piece in my webbing has been bent.

Charging base, 5V1A.

Common MicroUSB interface.

3、 Software

Scan the QR code on the packaging box, download and install the "Smart Sport" APP.

When the software was started, there was an advertisement. The user paid for the device and the service, but he gave me the advertisement. Alas, the advertisement was not screenshot anymore. It was sad.

Function introduction: exercise tracking, dynamic heart rate, ECG monitoring.

After registration, there are five items in the lower function bar, from left to right: family doctor, health information, START， ECG monitoring, personal center.

"Family doctor" shows that the family doctor service has not been opened in my area.

There are many articles in "Health Information".

The color picture in "START" is also a link to sports related articles.

First, connect the ECG belt to the mobile phone APP, and search for the connection in the "Device Management" in the "Personal Center". After the connection is successful, you can see the power of the ECG belt host here, and only here can you view it.

Firmware upgrade is very convenient. If you find a new version, you can directly click it to upgrade, and it will be completed quickly and smoothly.

Personal information should also be filled in. When indoor sports such as treadmills are used, APP tracks the movement through the G-sensor in the ECG band, and its calculation is related to the personal information filled in here, such as height, weight, etc.

Instructions for use of Xunzhi H1 ECG band. The special attention is the wearing position. Many people habitually wear it on the breast, but actually it should be under the breast.

In "ECG monitoring", "fast detection" is to automatically measure for 30 seconds and generate a report. "Manual detection" does not limit the time, but if the time is less than 30 seconds, ECG analysis, fatigue analysis and health indicator report will not be generated.

What is the principle of detecting fatigue?

The autonomic nervous system is the control center of the whole body organs, in charge of metabolism, respiration, cardiovascular, digestion, endocrine and immune system. The two major branches of the autonomic nervous system include the sympathetic (excitation) and parasympathetic (relaxation) systems.

Sympathetic nerve makes our heart beat faster, blood pressure higher, gastrointestinal peristalsis slower, and mobilize the energy of the whole body to cope with intense activities. The role of the parasympathetic nervous system is opposite to that of the sympathetic nervous system. It saves energy consumption of the body by slowing down the heartbeat and lowering blood pressure, and promotes the activities of the digestive and immune systems. The long-term excitement of the sympathetic nervous system will inhibit human immune function, leading to sub-health and even the emergence of diseases. The parasympathetic nervous system contributes to the rest and recovery of the body. The Smart Sport APP collects the user's ECG data through the ECG belt, extracts the heart rate variability parameters, and correlates the human sympathetic nervous system response to assess the current fatigue state of the user.

It seems that I really need to have a good rest. My lifestyle is very unhealthy.

There is only one "run" available for sports options, and you can set time or mileage goals. Here, once the time and mileage are selected, they cannot be reset, which is troublesome. Only after running once will it be the initial state after the next new start.

If you want to record while riding, please do not turn on "Auto Pause". If it is turned on, there may be a large section of stop recording during riding.

In addition to being connected with our own "Smart Sports", Smart H1 can also be used together with other commonly used sports apps. For example, I often use the "traveler".

It can be directly connected in "My Smart Device". Before connecting the "walker", disconnect it from the "quick intelligence movement".

Here, you can see the real-time heart rate value. At this point, I was very puzzled. When I first ran the "Smart Sport", I was looking for a place to display the real-time heart rate. I couldn't find it anywhere. This is a big disadvantage of native applications. Of course, it can be displayed in the process of movement, but that is not enough.

Later, the main interface will display more heart rates.

Heart rate alarm can also be set. There are many algorithms for the reasonable heart rate range of ordinary people. You can run several times to find a reasonable exercise heart rate range that you can bear.

The Android version of my own commonly used "Shanren Sports" APP cannot connect to the heart rate band at present, so the test cannot continue. The hardware of the Shanren Discovery smart code lamp is also unable to connect to the Xunzhi H1. I have consulted the people of Shanren and Audmont manufacturers about this, and they have different opinions. Please pay attention to those who intend to use in combination.

4、 Using

In the past night running time, Decathlon's entry heart rate was accompanied, and it was also very accurate. Several years later, there was still electricity. But it is not intelligent. It is troublesome to check the heart rate on the watch every night. Moreover, this is a real real-time heart rate value. There is no record, no statistics, no analysis, and the function is very simple, which is no longer suitable for intelligent today.

Wear two heart rate bands at the same time, and the readings are relatively accurate.

The ValleNow2 smart bracelet on hand, although it also has a heart rate meter, only supports static heart rate, but does not support exercise heart rate, which greatly reduces its practicability. The measured value is somewhat different, which can be used as a reference. The heart rate band is more direct and accurate.

Real time heart rate can be displayed during movement, and the interface can also be locked by pressing the lock on the upper right corner.

The track record is relatively accurate without drift. I can't run recently. I have run a lap by riding. If "Auto Pause" is enabled at this time, the whole riding process will not be recorded.

The data summary will be displayed on the "START" page.

5、 Summary

During the trial period, two product codes may appear in the text due to a small problem. During this period, my Meizu MX5 screen imploded, and my new NutPro mobile phone was launched. Later screenshots were also taken with NutPro. I used Meizu MX5 phone to connect in the early stage, and everything is normal.

As a Bluetooth heart rate belt, its compatibility is relatively good. The measurement results and basic data analysis can help users better understand their own physical conditions. There is no doubt about the importance of the heart. Obtaining your heart rate in a timely and accurate manner can largely avoid sudden death due to exercise. However, there are some shortcomings, The function of APP itself is not perfect, and there is no intuitive and convenient real-time heart rate display. The main family doctor service is not supported in cities like Shanghai. The sport only supports running, which is a little simple. We look forward to adding support for more sports.
