Embodiment Construction

[0027] figure 1 A schematic structural view of the present invention is shown. Such as figure 1 As shown, the main body of the telephone data terminal system consists of CPU, USB host chip, static RAM memory, E 2 ROM, modem, CPLD, USB interface, keyboard, display screen, telephone line interface, SD card, relay, LED indicator light, buzzer. The single-chip CPU is the core of the whole circuit. It adopts 8-bit high-performance and low-power microprocessor ATMEGA128 of ATMEL, and has 128K bytes of programmable Flash in the system. 256 general-purpose working registers + peripheral control registers, the performance is up to 16MIPS when working at 16MHz, with non-volatile program and data memory, which realizes in-system programming through SPI, and supports extended on-chip debugging, realized through JTAG interface Programming of Flash, EEPROM, fuse bits and lock bits. USB host chip, the CPU accesses the U disk through the USB host chip (the U disk adopts the FAT16 file sys...

Abstract

The present invention provides a telephone data terminal system using USB interface to realize data automatic transmission of manpower dial-up and data automatic transmission method thereof. The system includes a CPU, a USB host computer chip, a static RAM internal memory, an E2ROM modem, a CPLD, a power supply circuit, a USB interface, a keyboard, a display screen, telephone line interfaces, a SD card, a relay, an LED indicating lamp and a buzzer. The data automatic transmission method includes steps of procedure detecting U disk, initiating call by pressing dialing key on the keyboard, sending the data, off-hook , receiving data, and automatically breaking telephone connection. The inventive telephone data terminal system has advantages of simple operation, low professional requirement, convenience and shortcut(automatic data transmit-receive can be completed by dialing the telephone), and high efficiency.

Description

technical field [0001] The invention relates to a data transmission device, in particular to a telephone data terminal system and its data automatic transmission technology. Background technique [0002] A phone call cannot be separated from a telephone, a fax cannot be separated from a fax machine, and sending data on a hyper terminal cannot be separated from a computer and a Modem. The demand for modern data transmission is increasing day by day, but the means of data transmission still exist many inconveniences. There are generally two ways to transmit data on the computer, one is through the Internet, which requires a network connection, or use a Modem to access the Internet on the telephone line; the other is to use the Windows Super Terminal and Modem to transmit data on the telephone line, Regardless of which method, operators are required to have certain computer and network operation knowledge and skills. In addition, computer environment hardware and software ove...
