Special Mic GPS code table is good or the purpose and principle of the GPS code table is good
1. The working principle of GPS code watch
The GPS code table is a satellite positioning system, such as one or more of GPS/GLONASS/Beidou/Galileo. After receiving the sky satellite signal, the speed, distance, time, and height data are calculated., Power data.Finally, the intuitive and rich cycling data is obtained.
Almost all GPS code tables use the US GPS positioning system, but some code -watch manufacturers combine the advantages of GPS and other positioning systems to send a double -star positioning function.
2. The purpose of the GPS code table
The GPS code can display riding data such as distance, speed, altitude, temperature, heart rate, step frequency, and some very practical small functions, such as automatic backlight, automatic registered circle, line navigation, etc.
1. Heart rate monitoring: Heart rate monitoring Belt a sensor of the biological electrical signal (ECG signal) generated by myocardial excitement during the heart activity of the heart.
2. Step frequency records: Piece sensors are used to calculate the sensors that people step on the number of people per minute during cycling.The unit is: turn/minute.Installed on a bicycle or a crank after the bicycle.
3. Power records: The power meter is installed in the rear wheels, plates, cracks, pedals, or middle shafts. It can calculate how much sensors do people do in real time during cycling.
4. Automatic backlight: After GPS positioning, get position coordinates to obtain local sunrise and sunset time.Turn off the backlight an hour after the sunrise; turn on the backlight an hour before sunset.
5. Automatic regulation: It is divided into two types: distance measurement circle and location. When the distance is meter, a fixed distance is set. After the ride completes a fixed distance, it can be calculated.After the position is planned to move to the position where the circle point is located, it is suitable for ride around the circle.
6. Line navigation: Analyze history or plan riding data generation road books, providing precise navigation and returning flights.
Because each brand has different ideas and layouts of product design, the above points do not represent the functional attributes of all brand products.
Third, the GPS code table is better or ordinary code table
The GPS code watch uses a single and multiple satellite positioning systems for positioning, and then analyzes and shows through the GPS module in the code watch, and records various cycling data.
The traditional code table is to complete the record through the magnetic head induction.
2. Data function
The cycling data recorded by the GPS code can be as many as dozens of items, and it can be uploaded to the back -end websites of each GPS code watch brand or connected to the mobile phone APP for data analysis and data sharing.
The data that can be displayed by traditional code tables is limited, and data cannot be analyzed and shared.Many times you often need to take pictures manually to share sexual data sharing.
3. External device connection
The GPS code can be obtained with more comprehensive and rich cycling information through ANT link external devices, such as heart rate bands, stepping device, power meter, etc.
Traditional code tables can only be restricted. Except for a small number of high -end traditional code tables that can connect to the tramotor and heart rate band, other external equipment cannot be connected.
4. Convenience
The GPS code watch is simple to operate, and there is no need to set the step diameter and other steps. You can install it by installing the bottom of the gauge or extending the bracket.If there are multiple bases and brackets, a GPS code can be used for multiple vehicles.
The operation of traditional code tables is cumbersome, especially the wired code watch is called a technician killer. The aesthetics and convenience are deducted.
5. Power consumption and price
Rider who insists on using traditional bicycle giameters will use power consumption and price as an important factor in choice.A button battery of a traditional code watch can usually endure tens of thousands of kilometers, while the purchase price is only hundreds of yuan.The GPS code is limited by power consumption. In the case of low power consumption, it can only be battery life for 20-30 hours, and the price is often from several hundred yuan to thousands of yuan.However, in fact, this is a question of wise wisdom, and demand and purse determine everything.
