All-weather driving service system

Abstract

The invention relates to an all-weather driving service system, which comprises a centralized-control center server platform and a front-end portable vehicle-mounted terminal, wherein the front-end portable vehicle-mounted terminal comprises a CPU consisting of a main processor and a communication module, an SDRAM, an NAND FLASH and an NOR FLASH; a service center number and a network address of the centralized-control server platform are built in the front-end portable vehicle-mounted terminal; an antenna is connected to a radio frequency interface of the communication module in the CPU; the CPU is connected with a GPS chip through a serial port; and the CPU is also connected with a crystal oscillator and clock circuit. The all-weather driving service system integrates multiple functions, such as global satellite positioning, floating vehicle data acquisition, wireless data communication, real-time traffic navigation, weather navigation, voice access service and the like, has complete functions, is quite convenient to operate, ensures driving convenience and safety to the maximum, and can be applied to the fields of highways, city roads, waterway transportation and the like.

Description

technical field [0001] The invention relates to a navigation system, more specifically, to an all-weather driving service system. Background technique [0002] With the help of general GPS equipment, drivers can choose the optimal route with the shortest driving distance according to the destination, so as to avoid going wrong. However, static maps cannot reflect detailed dynamic road condition information, and the navigation function of GPS cannot give full play to its advantages during peak hours of traffic congestion. According to statistics from the China Communications Network, the average speed of drivers in cities such as Beijing and Shanghai during the rush hour is less than 20km / h, and the average per capita spends 2 to 3 hours a day on road traffic. Due to traffic congestion, the car is in a low-speed driving state for a long time, and the gasoline consumption will increase by nearly 50% compared with the normal driving state, and the exhaust emission is also much...

Problems solved by technology

Chinese invention patent application number 200810141016.9 discloses an anti-overspeed monitoring and recording device, which provides the function of anti-overspeed monitoring; After a kind of remedial measures, still there is driving unsafe factor, if can understand road real-time weather situation as early as possible, just can avoid dangerous weather, select a safest route for driving; Chinese invention patent application number 200610134395. A full-range highway monitoring device based on integrated navigation; but the above-mentioned devices only have a single function. If you buy them all, in addition to problems such as cost and placement space, the biggest problem is that it is inconvenient to operate and easily distracts the driver. , which is a huge threat to traffic safety
