Class (I) products belong to vehicle embedded/fixed GPS. This product is mainly characterized by wireless communication technology and information technology such as digital broadcasting, satellite communication and mobile communication, and takes the car as the receiving equipment to transmit information (satellite positioning, navigation, tracking, news, meteorology and stock market information) and multimedia (digital broadcasting, digital TV and online games) with external environmental resources in one or two directions. So far, the representative system product is Telemati. The second category of products belongs to vehicle-mounted portable GPS, and the representative products are Mio's "Mio A700" and "Mio A70 1" and ASUS's "P535". The main feature of this product is that it integrates mobile phone, PDA and GPS, and also has the functions of mobile communication and GPS satellite reception. The third kind of products belong to portable car GPS, and the surface products are "Mio 169" and "Mio269" from Yuda, "A636" and "RS232" from ASUS, and "P 100" from dopod. The main feature of the product is PDA integrated GPS (including active: using Bluetooth). (Ⅳ) The product belongs to embedded/fixed vehicle GPS. Representative products include Panasonic's CD-DV2300 DVD navigation system, Alpine's NVE-N077PS DVD navigation system, Colijn's NAX-9500E hybrid navigation system, Jianwu's NV-D9032 DVD navigation system, Jiaming's StreetPilot III Deluxe and so on. , product functions mainly integrate car CD, DVD or broadcasting equipment and GPS products.
From the perspective of regional market distribution, due to the relatively mature development of mobile services in Japan, South Korea and Asia-Pacific, coupled with the decline in the price of GPS chips, the chip size has been integrated from three to a single chip, and the power consumption caused by process and power management design has increased, with more emphasis on portable car GPS products. According to the statistics of Masterlink Securities, from 2004 to 2008, the total vehicle GPS shipments accounted for 90% of the global embedded/fixed vehicle GPS shipments in the vast North American and European markets. It is estimated that with the hosting of the 2008 Beijing Olympic Games and the 20 10 Shanghai World Expo, the proportion of China's vehicle-mounted GPS demand will gradually increase from 2007, and it is estimated that it will account for 8%~ 10% of the global embedded/fixed vehicle-mounted GPS shipments by 20 10.
Embedded/fixed vehicle GPS can be divided into pre-market (or original equipment (OE)) and post-market. The front market (BM) is the original factory market pre-installed by the original factory or the seller, and the rear market (AM) is the modification or retail market where consumers buy and install the vehicles after they are sold. According to the IEK research report, from 2004 to 20 10, the global embedded/fixed vehicle-mounted GPS system, stimulated by E-91in the United States and E-12 in the European Union, accounted for the proportion of BM/OE and AM shipments from 20000. Global BM/OE vehicle GPS shipments will increase from 5.729 million in 2004 to 2065,438+042,000, with a compound annual growth rate of 654.38+02.5%, and AM vehicle GPS shipments will increase from 654.38+750,000 in 2004 to 2007.
In addition to the three core requirements of vehicle positioning and navigation (providing driving information such as vehicle condition report, travel information and planning the best driving route). ), vehicle tracking (personal safety such as anti-theft tracking, etc. ) and fleet management (logistics fleet management, etc. ), vehicle-mounted GPS products that are compatible with automobiles and have two-way communication capabilities will have market development potential. As shown in fig. 6, vehicle GPS products are located in the fourth quadrant, although with the recent rapid development of vehicle multimedia systems, manufacturers such as Panasonic, Jianwu and Clarion have introduced products that integrate DVD player functions, digital broadcasting system (DAB) and DVD-type vehicle GPS system, increasing the value of products that mainly used DVD memory for maps, travel information, navigation and navigation information in the early days. However, due to the fact that the products are still not compatible with the driving information provided by automobiles, and the product price is as high as 1, 500 to 2,500 US dollars, the market advantage will gradually lose in the future with the decline of the price of Telematics products and the rationalization of the price of TSP service solutions.
1, unified platform
Set up a platform service center in the whole province (that is, data communication, exchange, processing and maintenance institutions including GPS monitoring system). Each client only needs to purchase a set of monitoring terminal software system, and is equipped with a microcomputer that can access the Internet, so as to realize the monitoring and management of the vehicle/ship, which is not limited by the region or outside the province.
2. Choose your own in-vehicle equipment
Considering the interests of users, the system platform is designed to be compatible with GPS vehicle-mounted equipment from multiple manufacturers, and the equipment manufacturers set up local equipment maintenance organizations. Users choose their own products from multiple manufacturers, and the manufacturers are responsible for the installation and testing of the equipment.
3. Mode of service
Users log on to the service website, apply for the service, and pay a certain service fee and mobile communication fee flexibly through online banking/bank transfer/post office remittance for half a year. , thus opening this service. Remote users can monitor and manage by purchasing monitoring terminal software (C/S) or directly using IE browser (B/S) for free. Users can input and manage their own vehicle/ship information. Large group users will be equipped with monitoring terminal software by the service center. The function of B/S mode is simpler than that of C/S mode, which mainly realizes the functions of positioning, playback, ground object query and so on. C/S mode can also send monitoring and alarm instructions to vehicle-mounted equipment at any time, and complete more complex functional requirements such as real-time monitoring, scheduling, statistics and reporting of monitoring targets in various States.
4. Maintenance mechanism of road network GIS electronic map
The traffic construction of real roads, streets, rivers and waters always precedes the drawing of relevant road networks on electronic maps. The system operator, software platform provider or electronic map provider will adopt advanced surveying and mapping technology to establish a long-term and perfect GIS electronic map surveying and mapping maintenance mechanism to ensure that GPS users can get correct road network instructions in time.
Running die
Because the operation mode of Telematics system is extremely complicated, the current development mode can be basically divided into GPS and Access. As for the operation mode of the GPS system, it is mainly connected with the satellite through its built-in three-way transceiver antenna with radio, microwave and satellite, and provides navigation guidance for the driving direction of the vehicle through the triangulation method of the satellite, the built-in GPS system and geographic information system (GIS) of the vehicle information system, and the topographic map (3D) or planar map. In terms of information receiving operation mode, information (such as transportation, hotels, entertainment, meteorology, booking, etc. ) receive and send with the background customer service center or information provider through the mobile communication network (GSM, GPRS or 3G), as shown in Figure 2.
