Description
Technical field
The utility model relates to the universal serial bus device technical field of electronic scales and compunlcation, specifically a kind of wireless serial interface device of realizing the HID plug and play by USB.
Background technology
The communication interface of existing weighing apparatus field and other equipment mainly is the CAN bus, the RS485 bus, RS232 serial line interface or Ethernet interface, and existing computer has been cancelled LPT device interface and serial device interfaces gradually, present general Ethernet interface and USB interface have only been kept, and the wiring of LPT device interface is complicated, RS232 serial port equipment need be installed the serial device driving or pass through the USB virtual serial port in computer end, and need corresponding messaging parameter be set according to equipment characteristic, and serial ports is based on the communication mode of connection, communication stability is poor, and computer ethernet interface quantity is few, the protocol layer complexity, and realization and application difficulty are big.It mostly is limited data transmission between existing electronic scale and the computer, the shortcoming of wire transmission is that communication distance is short, the usb data line can't transmit great distances, serial device bus long-distance transmissions need be strengthened and compensates signal, increase cost and wiring difficulty, very flexible can't realize outdoor and portable communications.
Therefore, to design a kind of adaptability good, easy to maintenance in order to overcome above-mentioned deficiency, uses that data transmission is a kind of flexibly to realize the wireless serial interface device of HID plug and play by USB, just the problem that faces of inventor.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of wireless serial interface device by USB realization HID plug and play, and it is simple in structure, and is easy to operate, and adaptability is good, and is easy to maintenance, uses data transmission flexible, and extraordinary effect is arranged.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of wireless serial interface device of realizing the HID plug and play by USB, comprise receiving end and transmitting terminal, it is characterized in that: described transmitting terminal comprises general serial equipment interface, interface protocol level conversion unit, microprocessor, wireless transmitter module, the general serial equipment interface is connected with the interface protocol level conversion unit, the interface protocol level conversion unit is connected with microprocessor, and microprocessor is connected with wireless transmitter module; Described receiving end comprises wireless receiving module, usb protocol interface storage control unit, USB interface, wireless receiving module is connected with microprocessor, microprocessor is connected with usb protocol interface storage control unit, and usb protocol interface storage control unit is connected with USB interface; Wireless transmitter module and wireless receiving module adopt wireless connections.
The beneficial effects of the utility model are:
1, wireless transmission is cheap, and the foundation of wire communication mode must be set up cable, therefore needs great amount of manpower and material resources; The wireless data transmission mode then need not to set up cable, only need connect wireless data transmission module in each terminal and get final product.
2, adaptability is good: the limitation of wire communication is too big, only be applicable to fixing particular surroundingss such as factory, extremely strong restrained force will be arranged the wiring installation of cable network, and the wireless data transmission mode will not limited by these, the wireless data transmission mode has better adaptability widely than wire communication thus, is subjected to environmental restraint hardly.
3, favorable expandability: after what a communication network the user sets up, usually because the needs of system increase new equipment.If adopt wired mode, need wiring again, it is cumbersome to construct, but also might destroy original communication line, if but adopt the wireless data transmission mode, only newly added equipment need be connected with wireless digital broadcasting station and just can realize the expansion of system, better expansibility is arranged by contrast.
4, the easier realization of plant maintenance: the maintenance of wire communication link needs along the circuit inspection, when breaking down, the general very difficult trouble spot of in time finding out, and adopt the wireless data transmission mode only need safeguard digital transmission module, the Shi Zeneng that breaks down finds out reason fast, recovers circuit and normally moves
5, wireless transmission plurality of specifications is optional is adapted to different transmission ranges, the various configurations application scheme, can satisfy the different needs of user, industry standard design, can work in various rugged surroundings, open ISM band need not to apply for frequency, and software and radio technique guarantees high anti-jamming capacity and low error rate.
