Positioning is divided into outdoor positioning and indoor positioning. Outdoor positioning is based on the principle of GPS + map implementation. Currently providing outdoor lbs is mainly Gaode, Baidu and other map service companies. Outdoor status products are represented by drops and hungry.
Indoor positioning is also inseparable from indoor navigation and positioning. However, unlike the GPS positioning principle, indoor positioning is a kind of geometric positioning, that is, allocating a base station indoors, based on the distance database, signal strength, and other resume database around the base station, and then determining the location of the user according to the intersection of the base station. Shopping malls, factories, etc. are the main application scenarios for indoor positioning. There are many ways to achieve indoor positioning and navigation, such as wifi and ibeacon in recent years. However, because of its low power consumption, easy deployment, high accuracy, and low cost, ibeacon is widely used today.
Ibeacon is a feature released by Apple. It is fully open for ios, Android, and winphone.
The working principle is that a device equipped with a low-power Bluetooth communication function uses the BLE technology to send its own unique ID to the surroundings, and the application software that receives the ID will take some actions based on the ID. For example, by setting up the iBeacon communication module in the store, you can let the iPhone and iPad run a message to inform the server, or the server can send discount coupons and store points to the customer. In addition, indoor positioning is also widely used (for example, Wanda Plaza, museums, parking lots, etc.).
Its basic implementation: According to the customer's CAD map and positioning algorithm to draw points, in accordance with the point map into a vector map, and then configure the ibeacon equipment according to the location, thereby completing a simple indoor positioning and monitoring; and according to the Positioning to complete other functions required by the business, such as alarms and other functions.
At present, WeChat also supports and can set up shakes and provide services in WeChat developers, mainly for shops. Currently, there are a lot of solutions based on ibeacon providing indoor positioning, and the solution is also relatively mature.
1, no match. Apple had strict control over Bluetooth devices before, so only Bluetooth devices authenticated by MFI can connect with iDevice, and Bluetooth 4.0 does not have these restrictions;
2, positioning accuracy, distance farther. Ordinary Bluetooth (before Bluetooth 4.0) The general transmission distance is 0.1-10m, and the iBeacons signal can be accurate to the millimeter level, and can support up to 50m range;
3, ultra-low power consumption. Bluetooth 4.0 is also called Bluetooth Low Energy. An ordinary coin cell battery can be used by a Beacon base station hardware for two years.
4, widely applicable. All devices equipped with Bluetooth 4.0 or later (except for iOS devices, Android and Windows Phone platforms can also be applied) can be used as transmitters and receivers of iBeacons technology.
Now iBeacon technology has amazing application cases in many places. Some search websites can easily search for a lot of relevant information by simply entering iBeacon technology. The application of iBeacon technology has started both at home and abroad, and interest-seeking electronics has played a leading role as a well-known enterprise in the industry. There are many cases of application scenarios in China. Such as: US Mission Review headquarters wisdom building, Xijing Hospital (The First Affiliated Hospital of the Fourth Military Medical University), Affiliated Hospital of Guizhou Medical University, 2016 Guiyang Digital Fair - Western Public Innovation Park, Jinan Jisi used car market, Suzhou Wuzhong Wanda Square and so on. At present, the domestic iBeacon application has become more and more perfect, and the entire industrial chain has begun to take shape. With the guidance of indoor positioning technology, the prospects for a wide range of indoor applications have opened up.
1. Intelligent explanation of attractions and pavilions
In traditional sights and exhibition halls, visitors have the need to listen to and explain. At present, most of the exhibition halls and attractions are literal explanations or guided tours. In fact, many times, they cannot fully meet the needs of tourists. The application of iBeacon technology can easily solve this problem. When users have requirements, they are naturally willing to turn on Bluetooth and receive relevant commentary voice or video information. Domestic Forbidden City, Summer Palace, and Humble Administrator's Garden are currently deploying iBeacon commentary and smart recommendation programs. With the fierce competition in tourism, most of the scenic spots may use iBeacon in the future to enhance the user experience.
2, shopping malls, shopping centers smart guide
Shopping malls and shopping malls are always crowded with people, and customers often get lost. Finding things and looking for directions often affect good shopping moods. iBeacon technology service providers have realized that the combination of traditional retail and mobile Internet will become a key to changing the physical retail industry. It closely connects customers and gives customers the best shopping experience. Indoor positioning, personal mobile shopping guides, real-time information push, user big data analysis, etc., are no longer empty talk. Through the iBeacon Bluetooth device covered in the mall, it helps brands and merchants find the true needs of customers and find the most suitable for their positioning; it helps the mall to complete the most realistic big data market research, complete the online and offline integrated data circulation, reflecting The differentiated and thoughtful service features of shopping centers have earned them reputation and economic benefits, and enhanced their market competitiveness.
3, the medical industry
The medical industry also needs the same kind of applications, and iBeacon's breakthroughs and innovations in the catering industry will certainly greatly improve the current status of the medical industry. From the electronic medical doctor to the assets of the hospital staff, the tracking and positioning of the assets will greatly improve the pure pain point of the hospital. After the patient arrives at the hospital, he completes the iBeacon's perception. He can complete the registration on the mobile phone without waiting in line, and he often spends a lot of time looking for a department in complex hospitals. With a network deployed in the hospital, patients can simply turn on Bluetooth and enter their destination on the relevant APP. In the day-to-day management, the hospital also needs this technology, the intelligent identification of medical care mobile rounds and bed care, patient medicines and specimens, real-time positioning of personnel and equipment, and wireless communication of patient calls, to promote patients and medical personnel. Real-time interaction between medical devices to build a one-stop integrated solution for the information and intelligence of the medical industry as a whole.
4, education industry and iBeacon
The combination of the education industry and iBeacon is also very much desired. Using related technologies and applications, when students enter the classroom, do they apply automatic sign-in to help teachers of education and training institutions to check the student's attendance status, which not only reduces the teacher's trouble in naming, but also effectively improves the student's attendance rate. Such a model should also be promoted to more kindergarten students and primary school students through the use of wearable devices, timely monitoring of children’s attendance, preventing student accidents and ensuring children’s safety.
