Abstract
The utility model discloses a vehicle-mounted wireless terminal which comprises a central processing unit; the central processing unit is connected with an external interface module in a bidirectional communication way through a first series port of the central processing unit, is connected with a displayer or handle through a second series port in the bidirectional communication way of the central processing unit, is connected with a GPRS (General Packet Radio Service) module in the bidirectional communication way through a third series port of the central processing unit, and is connected with a GPS (Global Position System) position module in a communication way through an analog UART (Universal Asynchronous Receiver/Transmitter) communication interface of the central processing unit.
Description
Technical field
The utility model relates to a kind of car wireless terminal that is installed on the vehicle.
Background technology
The port unreasonable distribution of the central processing unit of existing car wireless terminal (CPU) can be wasted the serial port resource of a lot of CPU if connect more ancillary equipment, and then has reduced the program operation speed and the memory space that has increased program of CPU.
The utility model content
The purpose of this utility model is to provide a kind of car wireless terminal of reasonable disposition port.
The technical solution adopted in the utility model is: a kind of car wireless terminal, comprise central processing unit, described central processing unit is connected with the external interface module both-way communication by its first serial, be connected with display or handle both-way communication by its second serial, be connected with GPRS communication module both-way communication by its 3rd serial ports, be connected with the communication of GPS locating module by its simulation UART communication interface.
The beneficial effects of the utility model are: adopt the distribution structure of port of the CPU of car wireless terminal of the present utility model not only can save the serial port resource of CPU, saved a lot of time but also handle for communication data, accelerate the speed of service of program, also reduced the memory space of program simultaneously.
