【Concept】 GPS navigator that can help users to accurately locate the current position and the destination is calculated in accordance with established travel through the map displays and voice prompts to guide users in two ways-line to automobile driving aids destination. ================================= 【Term structure】 Chip, antenna, processor, memory, display, speaker, keypad, extensions slots, electronic maps, navigation software 10 major components. ================================= 【System Terminology】 ----------------------
[Global Positioning System (Global Positioning System) referred GPS] 1 It is composed of three major space satellites, ground control, and user receiver and other components. 2 There are 24 satellites to form a distribution network, were distributed in six 20,000 kilometers above the ground, the tilt angle of the Earth's quasi-synchronous orbit 55 °, there are four on each track satellites in space. 3. GPS satellites orbit the earth every 12 hours a week, anywhere on the planet capable of receiving signals place from 7 to 9 satellites simultaneously. 4 There are a master ground station and five monitoring stations are responsible for satellite monitoring, telemetry, tracking and control. 5 They are responsible for the observation of each satellite, the observed data to the master station provides. 6 After the master station receives the data, calculate the exact position of each satellite at each moment, and through three injection station will send it up to the satellite, the satellite and then transmit the data to the user to the ground via radio wave reception end equipment. Note: This system was originally developed by the military in the 1970s jointly developed. ---------------------- [Navigation] 1 has a GPS system is also light enough to receive only the data transmitted GPS satellites to calculate three-dimensional position of the user, and the time direction and the moving speed of information, there is no path computing power. 2 GPS receiving equipment in the hands of the user in order to achieve the route navigation function also requires a complete device including hardware, electronic maps, navigation software, including car navigation systems. ================================= 【Function Terminology】 ----------------------
1, [global positioning satellite intelligent burglar alarm] When the vehicle is parked alert, and then open the door for a minute did not enter the correct password or a car is illegally moved (with a trailer towed 50 m), multiple alarm telephone voice alarm system automatically set an alarm to the monitoring center and owners; Alarm monitoring command center received vehicle information, while the exact location of the vehicle alarm, speed, direction of travel will be automatically displayed on the electronic map. ---------------------- 2, [emergency assistance] When the vehicle was hijacked or robbed the owner, the owner in the case of robbery unsuspecting, touch emergency alarm button, silent alarm. Alarm monitoring command center after being robbed of the vehicle position, speed and direction and other states will automatically be displayed on the electronic map intuitively. Cooperate with the police command center monitoring the vehicle real-time monitoring, listening devices to monitor the car starts moving, locking the vehicle location, recrimination flameout, audible alarm, security protection owners. ---------------------- 3, [car phone] The system combines the GSM technology, with all of the digital mobile phone network to make and receive local calls, international and domestic long distance calls and roaming services and other basic functions and new business. GPS positioning at the same time the alarm, GSM digital phone calls can still be normal. ----------------------
4, [scheduling management] Monitoring can take the initiative to understand the command center location and vehicle-specific information, so dispatchers can lead the way functions according to the requirements of motor vehicle drivers, vehicle guidance to choose the best path to travel. ---------------------- 5, [telephone Start] Cold winter or hot summer, motorists in advance via landline or mobile phone to start the engine, turn the car air-conditioning, so the car owners after a comfortable driving environment. ---------------------- 6, [Intelligent Voice Dialogue] All operating systems have voice prompts, easy to use, in the case of satellite positioning, but also by voice accurately quoted GMT. ----------------------
7, [network query] Installation of the system through a computer network owners can check on the Internet, even when separated by vast oceans owners, just log "China Intelligent Transportation Communication Network" to enter a user name and password, you can check the real-time vehicle location and status, and through computer vehicle control. ---------------------- 8, [Hotline] Owners through the "hotline" on the remote control and monitoring of vehicle registration command center to be able to enjoy many value-added services, such as emergency waiting, fuel, navigation, ticketing, hotel reservations, reservations and other services. ---------------------- 9, [automatic navigation] ◎ voice navigation: Advance to provide motorists with the intersection turn voice navigation system status, such as traffic information, like a wizard to understand the way to tell you how to drive to the same destination. Navigation is the most important function, so you do not need to watch the operation of the terminal, through the voice prompts can safely reach their destinations. ◎ Screen Navigation: In operation the terminal will display maps, and the location of the car now, driving speed, distance to the destination, planned route prompted turn indicator of the traffic information. ◎ re-planning lines: When you do not have a line running according to plan, or when the wrong intersection, GPS navigation system will be based on your current location, as you re-plan a new route to the destination. ================================= 【Reserved Integrate / Just Reference】 【Translation is by The Network】 |
