The user can share this information with teammates through the communication module. In addition, in order to prevent the user from being unable to use the Communication system, when the vital sign detection module detects that the vital sign information of the user is weak, it will automatically force to send help information to all teammates through the communication module, and the help information will be displayed on the teammate's display module. Detailed information includes sending time, sending location and sending When the user's vital signs status, remind teammates to provide assistance. Moreover, Lora communication technology can also realize wireless communication within a few kilometers without assuming a base station, which can effectively solve the problems of 3G and 4G networks in the wild and provide people with more effective protection.

Description

Smart bracelet based on Lora short-distance wireless communication

technical field

The invention relates to the field of electronic technology, in particular to an intelligent communication wristband for field exploration.

Background technique

In today's life, smart bracelets have become a decorative fashion, sought after and loved by more and more people. With the development of electronic information technology, bracelets with various functions have flooded into the market. However, most of these bracelets have single functions and cannot meet the needs of some special customers. Therefore, after research, the author decided to develop a smart bracelet for team field adventures. The wristband integrates transmission and reception, and can realize the detection of vital signs, identification of location information and field communication functions. Especially suitable for outdoor adventure lovers.

Utility model content

The purpose of the utility model is to provide a smart wristband, which uses sensor technology and communication technology to realize the function of intelligent search and rescue, and can timely and accurately grasp the vital signs and location information of teammates, thereby improving the safety factor during the expedition.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a smart bracelet based on Lora short-distance wireless communication, including: a ring body, a main battery, a chip, and a functional module. The functional modules include a vital sign detection module, a positioning module, a communication module, a display module, a power supply module and a central processing unit.

The vital sign detection module is characterized in that: the vital sign module includes a body temperature sensor, a heart rate sensor and a blood pressure sensor, which can respectively realize the detection of human body temperature, heart rate and blood pressure.

The positioning module is characterized in that the personal information is positioned through the GPS satellite positioning system.

The communication module is characterized in that it adopts Lora short-distance wireless communication technology, and realizes point-to-point communication by setting the spreading factor to identify different terminals. Compared with traditional GSM, CDMA and other communication methods, Lora communication technology has low power consumption and can achieve a certain distance communication without setting up a base station. It is not only suitable for field use, but also saves the space of the bracelet and realizes the miniaturization of the bracelet.

The display module is characterized in that it uses the latest 3D touch technology for touch control, avoiding the use of traditional function buttons on the bracelet to enhance waterproof performance. In addition to displaying time, it also supports displaying teammates' vital signs and location information. In addition, there is an emergency SOS function. When a team member presses the screen for 10 seconds, all nearby team members will receive the SOS signal from the SOS team member and continue to remind teammates that someone is calling for help.

The power module is characterized in that it manages the power supply of the entire system, reasonably controls the power consumption of the entire system, ensures the standby capability, and also adopts the method of supporting wireless charging for charging.

The central processing unit is characterized in that it processes the information of each module in a unified manner and controls the communication module to interact with other terminals, which is the core of the entire hardware.

The beneficial effects of the present invention are reflected in:

The design of the present invention aims to provide help for the vast number of wild sports enthusiasts. With the development of the economy, the number of domestic donkey friends and foreign wild hunting enthusiasts continues to increase. Unlike cities, the communication signals in these wild areas are often very poor. Bad, this also brings a lot of risks. Based on the frequent reports of missing donkey friends, it makes people feel deeply distressed, so the author provides a smart bracelet based on Lora short-distance wireless communication. This invention provides vital signs detection and teammate information sharing, which greatly improves people's safety. Assure.

Fig. 2 is a block diagram of the working principle of the utility model.

detailed description

As shown in Figure 1, the main components of the utility model are: watch strap, dial, buckle, lock ring.

The watch strap, buckle, and lock ring are structural parts, which are mainly used to fix the dial body and facilitate the user to wear it. The dial is an electronic part. The design of the dial is shown in Figure 2. It is mainly composed of a battery 1, a power management module 2, and a central processing unit. 3. The display module 4, the positioning module 5, the vital sign detection module 6 and the communication module consist of 7 parts. The power management module 2 is responsible for power management, including charging management and providing required power to corresponding modules. The positioning module 4 monitors its own location in real time and sends its location information to teammates when necessary. The vital signs module 6 is responsible for detecting basic information such as heart rate and blood pressure on the vital signs used. When the vital signs information of the user is abnormal, the central processing unit 3 will be notified, and the central processing unit 3 will start emergency measures, and immediately send the user's location information and The vital signs detection information is sent to all teammates through the communication module 7, and when the teammates receive the notification in the emergency state, the display module 4 will have an alarm prompting that there are teammates needing help. In addition to asking for help in an emergency, the user can also share his location information with teammates through the communication module 7, and query the current time map information and other information through the display module 3.
