发明名称 System and method for mobile school trip guard
摘要 A mobile terminal capable of tracking a position of the mobile terminal between a first location and a second location includes a memory, a controller and a positioning sensor. The memory stores executable instructions and route parameters between the first and second locations. The controller controls operation of the mobile terminal and executes the executable instructions. The positioning sensor determines position data of the mobile terminal. The controller executes instructions for tracking the mobile terminal position data relative to the route parameters and for directing transmission of a message to another device in response to the tracked position of the mobile terminal differing from the route parameters by a specified amount.
