A few days ago, Beijing voted to eliminate all taxis before the 2008 Olympic Games, stipulate the color of the replaced models and car bodies, and emphasized that all vehicles with new license plates and new operating procedures must be equipped with GPS satellite positioning. Vehicle security system. What is GPS? Why install it in a taxi?
GPS is an abbreviation of Global Satellite Positioning System. It originated in the United States and took 20 years to build with 12 billion dollars. The US Department of Defense designed this system to be mainly used in the military field, using satellites to track and monitor locked targets to achieve defense and rescue purposes. At the beginning, it was mainly the pilots who searched for the crashed plane and the skydiver. At present, it mainly provides navigation and tracking for all aircraft, ships, and land mobile vehicles, and locates some important military targets, and at the same time carries out effective protection or implements a thorough strike. In the two Gulf Wars, the coalition led by the United States, with the help of the GPS global satellite positioning system, carried out accurate positioning of all important military targets, moving targets, and public facilities in Iraq through scientific deployment of weapons and equipment of various arms. Missiles and shells were devastated with errors less than 5 meters.
The first positioning satellite was launched in 1978. There are now 24 positioning and navigation satellites in outer space in the United States. The European Community has also launched the Galileo satellite navigation and positioning system plan. This plan was completed in 2008 and the total construction was about 3.6 billion euros. China launched two GPS satellites in 2000 to form the Beidou navigation system, which indicates that China's GPS technology has also entered a new stage.
GPS has a wide range of applications. With the development of society, the military field has turned to civilian use, and it has penetrated into various fields of national economy and social life, such as: aviation, aerospace, public security fire department command and dispatch, transportation department motor vehicle management, financial special vehicle management, Civil vehicle tracking and anti-theft.
The operating principle of the GPS security system is: it combines GPS global satellite positioning system GSM global mobile communication system GIS geographic information system computer interconnection network to locate and track the locked target and realize the vehicle-mounted communication function. Install the terminal of the system on the selected object. The terminal receives the positioning information through the GPS antenna, and the GSM short message (or GPRS) transmission system transmits it back to the monitoring center through the dedicated line, and passes the vehicle's positioning information and additional information through the GIS geographic information. The system and computer network are reflected on the designated computer.
At present, China's GPS security system development has gradually matured, and its main functions are: national satellite positioning, remote control of oil and power cutoff, to achieve anti-theft and anti-robbery functions; concealed emergency alarm, in-car monitoring during alarm; overspeed and overload alarm Etc. Its main application areas are:
1. Public safety field: implement reasonable dispatching and management of various police vehicles, scientifically arrange police force, network with police stations, help improve the level of public security, especially for large important conferences, large sports events (such as the World Sailing Race, etc.), large exhibitions and Cultural activities can implement effective three-dimensional security protection; through 24/7 monitoring, it can effectively prevent the theft and personal injury of taxis, state official vehicles, and various private vehicles.
2. Traffic management area: Carry out positioning monitoring on taxis and long-distance passenger vehicles, which can not only ensure the safety of vehicles and personnel, but also strictly manage them to reduce various types of car accidents caused by speeding, overloading and other illegal driving. occur.
3. Financial and insurance field: real-time monitoring of bank's cash transport vehicles, escort vehicles, and business vehicles, to prevent accidents such as vehicle robberies, and to protect the safety of personnel and national property; by monitoring the vehicles purchased by bank mortgage loans, it can combat Malicious cheating. By controlling vehicle accidents and vehicle theft, the amount of compensation paid by insurance companies can be greatly reduced.
4. The field of public vehicle management: Satellite positioning can effectively strengthen the vehicle management of government departments and enterprises, improve the level of scientific dispatch, and reduce government administrative costs and business operating costs.
