[Abstract]:With the development of the society, the high-speed growth of the economy and the rapid increase of people's living standard, the people's living range is expanding continuously, and the frequency of people's travel is constantly increasing. While enjoying convenient transportation, people are constantly being entangled by various problems in the journey. In which the loss of luggage in the journey is the most outstanding issue. in that present era, people travel have the characteristics of fast moving speed, long travel distance, strange destination and the like, and meanwhile, the rail transit and the public transport facilities have the characteristics of high vehicle sub-frequency, large passenger flow, complex passenger components and the like, so that once the luggage is on the train and the bus, The taxi and other public transport facilities are difficult to retrieve. In addition, in the train station, the bus station, the airport and other people's traffic, the complicated place of the population is easy to carry out the baggage mistake, the lost condition. It is especially important to design a smart case system which can realize the functions of anti-theft, trackable and alarm, and has the functions of moderate cost, reliable and stable, and being beneficial to the expansion. The pull-bar box on the market is in poor performance in the travel, and can only be used to record the position of the draw bar box when the draw bar box is connected with the mobile phone, and the existing product can be basically powerless when the draw bar box is lost. And the existing intelligent pull rod box is used as an intelligent head with the word intelligence, which is generally not long in the endurance time, and basically adopts a dry battery. And can not realize the remote location and recovery of the draw bar box. Aiming at the defects of the product in the field, the invention provides an intelligent bag system based on the Internet of Things technology, which can carry out real-time path monitoring on the intelligent bag through the mobile terminal equipment, realize the loss alarm and the recovery function, not only can prevent the loss, but also can realize the open-box reminding, And the built-in lithium battery is different from the power storage function difference of the dry battery and can be directly charged by the chamber. And the exclusive intelligent pull-bar box APP is developed, so that the man-machine interconnection can be realized to bring a more convenient and more comfortable and safer traveling experience for the user. The system mainly comprises a positioning system, a motion state monitoring system, a communication system, a Bluetooth communication system and a mobile phone APP client. The positioning system is based on the GPS global positioning system. In order to realize the remote path monitoring, the strapdown navigation development is carried out in combination with the information fusion to realize the accurate and efficient positioning. The motion state monitoring system is based on the three-axis gyroscope and the accelerometer, and combined with the strapdown navigation algorithm in the positioning system, the attitude angle analysis algorithm is designed, so that the position angle of the case is accurately analyzed, so that the purpose of monitoring the motion state is achieved. The communication system is developed by using the GPRS module as the core, so that the case can be connected with the 4G mobile network, and when the case is separated from the user, the case can be communicated with the user through the 4G network. The Bluetooth communication system uses the Bluetooth 4.0 technology as the core to realize the link between the case and the mobile phone client, and meanwhile, the RSSI ranging algorithm is designed to realize the distance calculation between the case and the user, so as to realize the anti-theft function of the case, that is, when the case and the user are more than ten meters, the case and the APP simultaneously alarm. In addition, in order to experience the man-machine interaction, the system develops an app client based on the Android platform, and the built-in map realizes the visualization of remote location and recovery, anti-theft and state monitoring. Based on the hardware circuit, this paper mainly designs and develops the positioning, communication, Bluetooth and power supply. The STM32 processor is used as the main control chip of the system, and the circuit development of the Bluetooth, the communication and the positioning function is completed by using the SIM808. Based on the hardware development, the strapdown navigation and motion state monitoring algorithm is designed and the APP client is designed. Through the test, the circuit design of each part of the system is reasonable and reliable, the algorithm is stable and accurate, the operation of the APP is smooth, the expected design goals and requirements are met, and the basis for further optimization and upgrading of the intelligent bag system based on the internet of things technology is provided.
