Abstract
The utility model relates to a radio paging intelligence terminal, comprising a wireless receiving unit, a decoding unit, and a microprocessor unit. The microprocessor unit comprises a CPU chip, a large screen LCD display screen connected with the output port of the microprocessor unit, a touching screen input device, a button input device, and a memory unit connected with a data port of the microprocessor unit. The memory unit comprises a mass flash memory and a large capacity static random access memory (SRAM). The large screen radio paging intelligence terminal simultaneously provided with the keyboard and the touch screen can work at a plurality of frequency points, paging information classification can be realized, and large screen display can be adopted.
Description
The utility model is a kind of improvement of radio call information terminal, specifically, relates to a kind of large-screen Chinese radio call information terminal that has keyboard and touch-screen simultaneously.
Nearly all radio pager (being commonly called as beeper) all adopts the button operation at present, and screen is very little, and some machines can only show numeral, and full detail is all issued, transmitted and show by the form that the individual notifies from a phone call.These machines are notified from a phone call and can be met the demands as the individual, but just not much of that as information terminal, and can only be operated on the frequency, so its use is restricted.
The purpose of this utility model provides a kind of large-screen radio call information terminal that has keyboard and touch-screen simultaneously, can work on a plurality of frequencies, and with the paging information classification, adopt large scale display, and practicality is higher.
The purpose of this utility model is to realize like this, construct a kind of radio call information terminal, comprise the radio receiving unit that is connected to buzzer unit, vibrator units, the output of described radio receiving unit also is connected to decoding unit, the output of described decoding unit is received a microprocessor unit, it is characterized in that, described microprocessor unit comprises a cpu chip and the large-screen LCD display that is connected on its output port, be connected on the touch-screen input unit and the press key input device of its input port, and the memory cell that is connected on its FPDP.
According to the utility model provide the radio call information terminal, it is characterized in that described memory cell comprises that magnanimity dodges (FLASH) memory frequently
According to the utility model provide the radio call information terminal, it is characterized in that described memory cell comprises big capacity static random access memory (SRAM).
Described radio call information terminal according to the utility model provides is characterized in that, described radio receiving unit is an all-channel frequency conversion receiver.
Radio call information terminal according to the utility model provides is characterized in that described cpu chip is an asic chip, is built-in with the LCD driver element.
Radio call information terminal according to the utility model provides is characterized in that, described touch-screen input unit is transparent resistor-type digital touch screen.
Radio call information terminal according to the utility model provides is characterized in that, described touch-screen input unit is installed on the described large-screen LCD display.
Radio call information terminal according to the utility model provides is characterized in that described touch-screen and external key can be operated simultaneously.
Implement the radio call information terminal that the utility model provides,, can in a frequency range, change the operating frequency of receiver automatically, receive the radio paging signal of whole frequency, improve the applicability of receiving equipment greatly owing to adopt the frequency conversion receiver.Simultaneously, it is more complete to select for use big screen LCD that information is shown, makes it really become the terminal equipment of a kind of wireless receiving, large scale display, and can simplify display operation; In addition, the touch-screen that is located on the LCDs can directly be operated last menu prompt and the content that shows of LCD, and is convenient directly perceived.Radio call information terminal that the utility model provides adopts static memory as receiving data storage device, and its memory capacity is big, can occur overflowing warning hardly, and power down can obliterated data, and practicality is higher.
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the logical construction schematic diagram of the utility model radio call information terminal.
