Description

Low-power triggering type automatic positioning charging system and method for indoor mobile terminal Technical Field The invention relates to the field of interdisciplines in the technical field of intelligent charging and automatic robots, in particular to a complete system and a complete method which are integrated in an indoor environment, automatically triggered by a low-power state of a mobile terminal, accurately positioned, grabbed and transported by an unmanned aerial vehicle, and capable of realizing automatic charging and automatic returning after completion. The invention is especially suitable for indoor scenes with complex space structures such as families, offices and the like, and aims to solve the problem of endurance management of small mobile terminals (such as smart phones and tablet computers). Background Along with continuous iteration of functions of mobile terminals such as smart phones and tablet computers, power consumption is continuously improved, cruising ability becomes one of core factors influencing use experience of users, in indoor daily scenes such as families and offices, users often forget to charge the mobile terminals due to compact work and life rhythm, or the situation that a charger is not nearby is found when the electric quantity of the mobile terminals is exhausted, even if the charger is equipped, the charger is also required to be manually connected with a charging wire or the position of the mobile terminals is adjusted to adapt to a wireless charger, and an obvious convenience short plate exists in an operation flow. According to the industrial investigation data, about 68% of users experience the problem of use interruption of the mobile terminal caused by insufficient electric quantity, wherein charging is forgotten, a charger cannot be found, and the charging operation is complicated, which are three main causes, and currently, the charging scene of the mobile terminal still depends on the mode of active operation of the user and fixed charging equipment, so that a charging solution for indoor daily scenes, such as unmanned intervention and automatic response, is not formed, and convenience and intelligent requirements of the users on the endurance guarantee of the mobile terminal are difficult to meet. Especially, the mobile terminal has become a core tool for modern life and work, the functions of the mobile terminal are increasingly powerful, the power consumption problem is also increasingly remarkable, under the indoor scene, the contradiction between the experience requirement of the user on the terminal for ' never power off ' and the charging mode depending on manual operation ' is increasingly sharp, and the prior art scheme has a plurality of inherent defects, but cannot realize real unmanned and full-automatic closed-loop charging. For example, fixed charging equipment technology (such as a wired/wireless charger) is essentially "terminal finding equipment", the core defect is that the technology relies on the active memory and manual operation of a user completely, the user must realize that the terminal needs to be charged and physically move the terminal to the position of the charging equipment, the core pain point of forgetting to charge cannot be solved obviously, in addition, because the charging equipment is fixed in position and limited in coverage range, if the charging process is interrupted in other areas (such as sofas and bedside) in the user, the convenience is greatly impaired, and the technology belongs to common knowledge and widely exists in various consumer electronic products. For example, mobile charging equipment technology (such as a charger) and a wheeled charging robot) is a great improvement in the technology of trying to find a terminal, but still does not realize a closed loop, the charger is a movable fixed charger, the user still needs to manually connect, the problem of secondary operation exists, the user needs to charge regularly, and the maintenance cost of the user is increased, while the desktop mobile charging robot disclosed in the wheeled charging robot (such as CN 214499987U) can move, but the wheeled driving structure severely limits the moving range of the desktop mobile charging robot, cannot cross tiny barriers such as desktop edges and ground cables, cannot cover non-desktop planes such as sofas and beds, and has extremely poor scene suitability, and more importantly, the scheme of the traditional robot lacks the function of automatically returning after the charging, so that the user still needs to find the terminal after the charging and cannot form a complete service closed loop. For example, the unmanned aerial vehicle related charging technology shows the potential of air transportation, but the design of the unmanned aerial vehicle related charging technology is originally different from the application scene and the indoor small terminal charging requirement of the invention, aiming at the cha
