Handheld communication terminal

Abstract

This invention relates to a handheld communication terminal, which comprises a central processing unit, a communication module, a GPS module, an interphone module and a display module, wherein the central processing unit controls the work of each module respectively through a serial port; the communication module communicates with other handheld communication terminals through a mobile communication network; the GPS module searches to obtain geographical position data of the positioned handheld communication terminal and then transmits the data to the central processing unit through the serial port, and the central processing unit performs analytical processing and transmits corresponding electronic map information to the display module to display; the interphone module is communicated with other handheld communication terminals in certain range through a command center; and the central processing unit sends instructions to implement switches, and the communication module or the interphone module is used for performing communications with other handheld communication terminals.

Description

technical field [0001] The invention relates to the communication field, in particular to a multifunctional police handheld communication terminal with GPS positioning function. Background technique [0002] With the development of the current society, the scope of GPS (Global Positioning System) positioning function is more and more widely used, and its purpose is to provide users with satellite positioning and navigation functions. At present, most of the GPS is realized by using pure hardware, which is not only expensive, but also realizes a relatively single function, and the expansion of the electronic map used is relatively cumbersome. [0003] And the GPS module that occurs at present can solve these problems more conveniently, insert GPS module on the interface of PDA, the operating system that PDA provides will control GPS module, be responsible for showing graphical interface to user by electronic map software simultaneously, like this It is much more convenient f...
