Abstract
The invention relates to the technical field of universal serial bus equipment for electronic scale and computer communication, in particular to a device for achieving plug and play of a somatology input device of an HID by means of universal serial interface data through a USB. The device is easy to use, a real plug-and-play function is achieved, the device is directly inserted into a USB interface of a computer, no drive needs to be installed, the device supports Windows XP and Window 7 systems, a user does not need to set any parameter, communication data can be directly input into a textbox, Office and other readable and writable software according to preset communication parameters, a carriage return and upward, downward, leftward and rightward keyboard control keys can be automatically operated, control characters can be self-defined, great convenience is brought to the user, and the user does not need to do anything.
Description
Technical field
The present invention relates to the universal serial bus device technical field of electronic scales and compunlcation, specifically a kind of device of USB (universal serial bus) data being realized to HID anthroposomatology input equipment plug and play by USB that is applied to.
Background technology
The communication interface of existing weighing apparatus field and other equipment is mainly CAN bus, RS485 bus, RS232 serial line interface or Ethernet interface, and existing computer has been cancelled LPT device interface and serial device interfaces gradually, current general Ethernet interface and USB interface are only retained, and the wiring of LPT device interface is complicated, RS232 serial port equipment need to be installed serial device driver or pass through USB virtual serial port in computer end, and need to corresponding messaging parameter be set according to equipment characteristic, and serial ports is the communication mode based on there being connection, communication stability is poor, and computer ethernet interface quantity is few, protocol layer complexity, realization and application difficulty are large.
Therefore, for overcome above-mentioned deficiency design one can compatible multiple serial device interfaces, can use again simply, realize a kind of USB (universal serial bus) device of realizing HID plug and play by USB of real plug and play, the problem that inventor faces just.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of USB (universal serial bus) device of realizing HID plug and play by USB, it is simple in structure, easy to operate, can compatible multiple serial device interfaces, can realize again real plug and play, there is extraordinary effect.
The technical solution adopted for the present invention to solve the technical problems is: a kind of USB (universal serial bus) device of realizing HID plug and play by USB, comprise general serial equipment interface, interface protocol and level conversion unit, microcontroller, usb protocol and interface storage control unit, USB interface, it is characterized in that: described general serial equipment interface is connected with interface protocol and level conversion unit, interface protocol and level conversion unit are connected with microcontroller, microcontroller is connected with usb protocol and interface storage control unit, usb protocol and interface storage control unit are connected with USB interface.
The invention has the beneficial effects as follows:
1, compatible multiple serial device interfaces, CAN equipment interface, RS485 industrial bus interface, RS232 serial ports etc.;
2, support plurality of devices agreement; support most of electronic scaless on the market; can from electronic scales communication data, extract useful data; for example: from the extracting data of electronic scales transmission as net weight, gross weight, steady; the information such as overload; and there is order sending function, for example, can control electronic scales zero setting, peeling etc.;
3, use simply, realize real plug and play, be directly inserted in the USB port of computer, without any driving is installed, support Windows XP and Window7 system, without user, any parameter is set, according to the messaging parameter setting in advance, can directly communication data be input to text box, in the read-write software such as Office, automatically perform carriage return, the Keyboard Control button such as up and down, and can self-defined control character, have great convenience for the user, do anything without user.
