By the above structure, drive program with serial port converting USB developed on embedded operating system platforms like Android, Wince and Window. By the use of the equipment for conversion from UART interface to USB dual mode interface, multiple-platform equipments like cell-phones, tablet computers and PC computers are connected with collection terminal with UART interface and data collection is achieved.
Description
Technical field
The utility model relates to data acquisition, checkout equipment field, is specifically a kind of interfacing equipment that converts USB Host/Slave bimodulus mode from the UART interface mode to of uploading for the signal detection process sampled data.
Background technology
Along with the development of mechanics of communication and ic core chip technology, the USB chip has been widely used in the data communication of electric room.Most of acquisition terminal can turn by the USB as CH341, CP2102 special use serial port chip and be connected with PC is convenient.But along with the development of mobile phone, panel computer embedded intelligent equipment and Android, Wince embedded OS, increasing user wishes to control with data sampling acquisition terminal by the Mobile Embedded intelligent terminal and monitors.This just need to increase USB Host interface and support to realize support to the mobile phone embedded intelligent terminal and its exchanges data on original acquisition terminal.The chip of existing a lot of USB bimodulus patterns is connected MCU mainly with the mode of parallel port and is connected with acquisition terminal, need manufacturer to realize USB chip bottom layer driving is supported.A lot of acquisition terminal manufacturer is to the control mode of the data transmission of USB and be unfamiliar with, and this increases on certain procedures and designs and difficulty.Some manufacturers can increase a USB module again and realize the mobile phone support between mobile phone and equipment, thereby increase the redundancy of cost and system.
Summary of the invention
The purpose of this utility model is the problem that exists during two kinds of USB embedded intelligent equipments of solution above-mentioned acquisition terminal and principal and subordinate are connected, and proposes to use one chip to realize that the UART interface conversion becomes the equipment of USB Host/Slave bimodulus interface.
The USB bimodulus interfacing equipment of the UART acquisition terminal that the utility model proposes, its main control chip be Vinculum II chip take FTDI company as modular converter, open two USB port simultaneously, and be configured to respectively Host and Slave pattern.Modular converter sends the USB end data to the UART interface, thereby realizes carrying out data acquisition and control with mode and the acquisition terminal of USB.Acquisition terminal manufacturer need to not carry out the Host of USB and the technological development of Slave interface function at the MCU end like this, only need continue to keep the data transfer mode of UART in equipment end.
Whether there is Device equipment to insert on the interruption monitoring facilities monitoring port of Host port, enumerate the initiation that with USB device communication shake hands of realization to equipment, and change transmission procedure by Host and make between UART end and USB end sampled data and control data and transmit transmission at equipment room.Whether the interruption of Slave port monitoring has main process equipment to initiate data or command request, and change transmission procedure by Slave and make between UART end and USB end sampled data and control data transmit transmission at equipment room.
After the utility model adopts above-mentioned technology that the data-switching of the UART communication modes of acquisition terminal is become the transmission mode of USB, USB port is carried out communication with the HID protocol mode, the HID of USB is the moving support of free drive under Android, Wince existing on PC end, mobile phone, panel computer embedded intelligent equipment end, Window system, is convenient to the exploitation that the user carries out application program.
Description of drawings
Fig. 1 is device structure schematic diagram of the present utility model;
Fig. 2 is that UART of the present utility model turns USB dual interface circuit figure.
Embodiment
Specific embodiment in conjunction with above-mentioned accompanying drawing 1-2 explanation utility model.
The utility model is characterized in that comprising as shown in Figure 1, and UART communication interface module 2, UART turn USB interface modular converter 3, USB HOST port 4, USB Slave port 5.The connected mode of above-mentioned module is: acquisition terminal 1 turns USB interface modular converter 3 by UART communication interface module 2 with UART and is connected, UART turns USB interface modular converter 3 and is connected with the embedded control platform such as PC, ARM 7 by USB HOST port 4, UART turns USB interface modular converter 3 and is connected with mobile phone, panel computer embedded intelligent equipment 6 by described USB Slave port 5, converts the USB communication modes of the master/slave arrangement of corresponding HID agreement to by the communication modes of UART to realize sampled data.
Be connected with acquisition terminal 1 by UART communication interface module 2, carry out exchanges data with the UART communication interface mode; Turn USB interface modular converter 3 by UART and the packet of UART communication modes is converted to the packet of USB HID communication modes, then pass through USB HOST port or USB Slave port transmission to the intelligent terminal of USB interface.Make the acquisition terminal of UART interface can compatiblely connect USB HOST equipment and USB Slave equipment.
Fig. 2 UART turns USB dual interface circuit figure, and its main control chip is that Vinculum II chip take FTDI company is as modular converter.On hardware, its 25USBlDM and the 26USB1DP pin data-interface as HOST USB end, 29USB2DM and 28USB2DP pin be as the data-interface of Slave USB end, thereby realize being connected with principal and subordinate's embedded intelligent equipment USB.Common IO mouth 31 is become TXD and the RXD port of UART interface with 32 pin configuration, thereby realize being connected with the UART mode of acquisition terminal.
After the module electrifying startup, at first HOST and Slave port are carried out initial configuration.Then whether there is Device equipment to insert on the interruption monitoring facilities monitoring port of Host port, enumerate the initiation that with USB device communication shake hands of realization to equipment, and change transmission procedure by Host and make between UART end and USB end sampled data and control data and transmit transmission at equipment room.Whether the interruption of Slave port monitoring has main process equipment to initiate data or command request, and change transmission procedure by Slave and make between UART end and USB end sampled data and control data transmit transmission at equipment room.Be identified as HID equipment at Android, Wince embedded OS descending device, and by HID data reading manner, equipment carried out uploading and processing of data acquisition in PC, mobile phone, panel computer end application program.
