Task scheduling-driven network navigation method

Abstract

The invention discloses a task scheduling-driven network navigation method, and relates to a wireless navigation method using GPS positioning information. The method comprises the processes that a scheduler issues a task to a performer, the performer receives and responds to the task, the performer performs the task and the performer feeds the performance situation of the task back to the scheduler, wherein in the process that the performer performs the task a management center plans a navigation path and issues part of path information and a map sheet by wireless communication according to a request of a PDA navigation terminal of the performer; the PDA navigation terminal receives the part of the path information and the part of the map sheet, goes into a navigation state, displays the map sheet corresponding to the current position and processes navigation events, and the management center continues to issue another part of the path information and the map sheet if the current position is beyond the issued part of the path range or the map sheet range; and the performer arrives at a destination based on the navigation prompt of the PDA navigation terminal and completes the task specified by the task command.

Description

technical field [0001] The invention relates to a wireless navigation method using GPS positioning information. Background technique [0002] At present, when each unit is carrying out remote task scheduling, the dispatcher often informs the executor of the task content and execution location by calling, texting or sending E-mail, etc.; The destination executes the task; then, the executor reports the task execution status to the dispatcher by calling, texting, or sending E-mail. When the performer is not familiar with the road and traffic conditions, it is very difficult to choose a route and get to the destination; therefore, the help of maps and navigation equipment is required. To this end, manufacturers of major handheld computers (PDAs) and mobile phones have successively launched PDA navigation terminals with navigation functions. This PDA navigation terminal is equipped with a satellite positioning (GPS) receiver; most of them are local navigation, that is, the ele...

Problems solved by technology

Its advantage is that the navigation processing speed is fast, but it is necessary to use flash memory with corresponding electronic maps in different regions and different periods, which not only increases the hardware cost, but also causes misnavigation due to the map information not being updated in time

In addition, for the dispatcher of remote task scheduling, even if each object can use the above-mentioned PDA navigation terminal to select a path locally and go to the destination to perform the specified task, when there are many managed objects (executors) and each When there is more than one task for an object, it is not convenient to maintain real-time communication with each object only by the manual operation of the dispatcher, and it is also difficult for the dispatcher to effectively manage various tasks of each object and understand each object in real time. performance of tasks
