Smart location tracking systems can be applied in many areas. For example, older people and children can avoid losing, and pets can lose. With regard to positioning system hardware, appropriate expansion can be applied in other areas, such as increasing temperature sensors and attitude sensors that detect forgotten children in school vehicles.
The hardware for this project consists of the application of base station-aided positioning, the positioning of the satellite GPS, a single machine of high value value, and the GSM module, temperature sensor, attitude detection sensor. The software system consists of server intermediate software and mobile phone APP.
With the development of Internet technology, wearable technologies have matured, combining hardware and software, using hardware sensors to access user walkways, distances, steps, and historical data query functions to enable users to learn about themselves during sports. For professional athletes, it is easy to analyse best routes while preventing cheating. For sports fans, you can share your sports data at any time, while keeping a record of how many calories are consumed and how many kilometres you travel.
Smart shoes involve a wide range of technologies, including the use of mercury switches, and the use of transmission technology for bluetooth transmissions, although they are sometimes susceptible to disruption and can be transmitted via a 4G network. Positioning techniques are mainly based on GPS, which is more precise, with smaller errors, and sometimes mobile phone base station positioning, with greater accuracy where the base station is large, and save electricity, with the disadvantage of having greater error in continuous positioning. In addition, smart shoes require the design of circuit boards, taking into account the miniaturization of the GPS antenna and the power voltage problem. When it comes to servers, you can use PHP, GO as the back-end processing language, you can process the backend, you need javascript, html if you make a web page, you need java or swift, etc. if you're a rooter, you need to use java or swift, and so on. The database needs to take into account redundancy in the amount of data, optimization of databases, secure processing of interfaces, prevention of collisions, etc. and security of databases.
- 2.1 User demand analysis
Software platforms require basic user operations, users download APs, register, activate and bind smart shoe devices, select dates to display map data, select real-time display of map data, view current user activity, current weather conditions, consumption of calories, steps, walking kilometres, and share their own motion data with others, by scanning 2-dimensional codes. Map routes show colour gradients based on the user's speed of running. For administrators, it is necessary to enable managers to view user data.
- 2.2 Application technology analysis
For a motion type APP, real-time display of motion data, GPS positioning data are critical, and each user software needs to respond to the large number of requests for back-end servers in a language that can withstand large-scale service requests, where we use the nodejs' Express framework, and node as a walk-in processor to respond to a large number of real-time requests, and Nodejs is the language of a powerful front-end intervention back-end server using a script that was originally used as a front-end script. Language javascript runs backend servers. The Express framework is an excellent backend development framework that follows the principles of simplicity, speed and openness. The frame generator provided through the official network enables the rapid generation of frame directories, including entry bin folders, route route folders, public folders containing mainly javascript files, pictures, styles, which are generated mainly to allow for the quick display of a page with this frame, because there is also a view folder below, which can store jade files, which can be set up, and which can be used to create a web page. In support of the ejs file format, the main purpose of using the jade file as a front-end html page is to load it quickly, as Jade has reduced the number of div tags in html by formatting them, so that the main tags in html are finally displayed and the rest of the duplicate symbols are removed.
In addition, in the case of APs, it was decided to use the Bootstrap framework, Bootstrap the simplified and harmonized code, with the aim of involving many people, while project codes developed over a long period of time remained as if they were completed by one person, in order to solve the problem. The most common problem in the distribution process is that not only the original code preparer may not understand the code for a long time, but the developer who continues to develop it later has no access to the code. The CSS Style Adjustment project in the frame is considered to be one of the bright spots of the Bootstream frame, and it is well known that the most trivial adjustment to the front page is the page style adjustment, which, through the Bootstream frame, has been substantially improved and, for users, needs only the corresponding fine-tuning of the specific style, and that the style adjustment will be widely applied to all pages without the problem of disagreement between the pages.
