Vehicle mounted positioning navigation terminal facing emergent rescuing

Abstract

The invention provides an on-board positioning navigation terminal which faces to emergency rescue, consisting of a host machine module, a power supply module, a GPS satellite positioning module, and a GPRS wireless communication module; the terminal is operated by a liquid crystal touch screen, information such as coordinates, direction, velocity, etc. are gained by the GPS module, the communication to a remote monitoring dispatching center, reporting the GPS information or receiving the emergency rescue dispatching information are carried out by the GPRS wireless network. The on-board positioning navigation terminal has two navigation types: self-navigation and controlled navigation and can realize the navigation from the current position to any coordinate position within a certain range. Furthermore, the on-board positioning navigation terminal can also provide a plurality of functions such as alarming and automatic updating, etc.

Description

technical field [0001] The invention relates to a vehicle-mounted positioning and navigation terminal for emergency rescue. Background technique [0002] At present, the equipment used for emergency rescue is mainly radio communication equipment. When an emergency occurs, the dispatch center first needs to inquire the drivers of each vehicle through the radio communication equipment to obtain the current location of each vehicle. The location where the driver's emergency occurs (hereinafter referred to as the alarm point), and then each driver travels to the alarm point separately. [0003] According to the basic flow of the current emergency rescue described above, the following situations may delay the rescue time: [0004] (1) Since the dispatch center needs to ask the driver to obtain the current location of each vehicle through radio equipment, the inquiry process will be delayed for a certain period of time. If the driver is not familiar with the area where he is loc...

Problems solved by technology

[0004] (1) Since the dispatch center needs to ask the driver to obtain the current location of each vehicle through radio equipment, the inquiry process will be delayed for a certain period of time. If the driver is not familiar with the area where he is located, the delayed time will be more;

[0005] (2) The alarm point is notified to the driver in the form of verbal command, there is no text or image data available for viewing, the driver needs to keep in mind the alarm point, which increases the burden on the driver; if the driver forgets the alarm point, you need to ask the dispatch center again;

[0006] (3) In the process of driving to the alarm point, the driver needs to choose the route independently according to his own understanding of a certain area. If the driver is not familiar with the current area, he will spend a lot of money in the process of going to the alarm point. time, even unable to find the alarm point
