Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The invention provides a full-life cycle tracking schoolbag, aiming at the problems that the existing schoolbag cannot be accurately positioned, the weight of the schoolbag cannot be known, and the schoolbag cannot analyze the state condition of the probability per se.

As shown in fig. 1, an embodiment of the present invention provides a life cycle tracking bag, comprising: a master control system; the first end of the overweight detection module is electrically connected with the first end of the main control system, and the overweight detection module is used for detecting the bearing state of the schoolbag in real time; the first end of the GPS positioning module is electrically connected with the second end of the master control system, and the GPS positioning module is used for automatically positioning the specific position of the schoolbag; the display module is electrically connected with the fourth end of the master control system; and the signal transmission module is electrically connected with the third end of the GPS positioning module.

The full life cycle tracking schoolbag of the embodiment of the invention comprises the following components: the system comprises a main control system, an overweight detection module, a GPS positioning module, a display module and a signal transmission module. The SIM808 module is used for completing the GPS positioning of the schoolbag system and uploading and updating of server data, so that the schoolbag has the function of positioning in real time. The weight detection module can detect the bearing state of the system in real time, so that the schoolbag has overweight detection, and the adopted millet mobile power supply can provide endurance capacity lasting for 5 working days for the system.

wherein, the master control system includes: and the first end of the mobile power supply system is electrically connected with the third end of the master control system, the second end of the mobile power supply system is electrically connected with the second end of the overweight detection module, and the third end of the mobile power supply system is electrically connected with the second end of the GPS positioning module.

In the embodiment of the invention, for implementing the schoolbag load analysis according to the age state of the student, STM32 is adopted as the core controller of the whole system.
