Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] According to the obtained longitude and latitude information of the current location of the controlled terminal, the present invention searches the electronic map for the point of interest (Point of Interest, POI) closest to the current location of the controlled terminal, and then takes the current location of the main control terminal as the starting point Ground, the point of interest closest to the current location of the controlled terminal is used as the destination to calculate the tracking navigation path, and navigate the user according to its current location, moving direction, spee...

Abstract

A navigation method based on position-monitoring includes sending position request message with position obtaining command to controlled end by controlling end through mobile radio network, sending position report message with longitude-latitude information of present position back to controlling end by controlled end after said request message is received and longitude-latitude information is calculated out by controlled unit, seeking interested point nearest to present position of controlled end in electronic map based received information and calculating out navigation path by controlling end according to said present position and said interested point.

Description

technical field [0001] The invention belongs to the field of navigation, in particular to a navigation method and equipment based on position monitoring. Background technique [0002] Global Positioning System (GPS) is a high-tech positioning product that can achieve high precision, all-weather, high efficiency, multi-function, easy operation and affordable price. And Global System for Mobile Communications (Global System for Mobile Communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA) system etc. can not only provide voice information that people are familiar with, it can also communicate between GPS and users, Through the data service and short message service, the control and positioning information can be transmitted very well, which provides a basis for the low-cost application of high-tech positioning products such as GPS in the folk. Therefore, the product of the combination of GPS and GSM or CDMA technology will satisfy people's...
