Abstract
The utility model provides a wireless data transceiver for a universal serial bus (UBS) interface. The wireless data transceiver for the USB interface comprises a USB interface module, a master control module and a wireless transceiving module, and is characterized in that the USB interface module, the master control module and the wireless transceiving module are connected in sequence. The master control module finishes the data acquisition of a measured and controlled object, controls the USB interface module and the wireless transceiving module, transmits the acquired data to a remote control centre through the wireless transceiving module or transmits the acquired data to a local computer through the USB interface module. The wireless data communication between the local computer and the remote control centre can also be realized. The data communication among the local computer, the measured and the controlled object and the remote control centre is realized.
Description
Technical field
The utility model relates to a kind of transceiver, especially the wireless receiver of USB interface.
Background technology
USB interface is the most frequently used interface of present computer, and the computer data transmission under a lot of situation all adopts USB interface to realize, but USB interface is wired pattern, in some industrial circle and the demanding place of mobility, carries out transfer of data and communication inconvenience.
Summary of the invention
In view of above these situation, the utility model provides a kind of wireless receiver of USB interface.Adopted low transmitting power, high receiving sensitivity designing technique, USB interface and wireless data transmission have been combined.
The utility model provides a kind of wireless receiver of USB interface, comprises usb interface module, master control module, radio receiving transmitting module, it is characterized in that: usb interface module, master control module, radio receiving transmitting module connect successively.The master control module is accomplished data acquisition, control usb interface module and the radio receiving transmitting module of observing and controlling object, and the data of gathering are sent to far-end control centre or are transferred to local computer through usb interface module through radio receiving transmitting module.Also can realize the RFDC of local computer and far-end control centre.Realize the data communication between local computer, observing and controlling object and the far-end control centre.
The beneficial effect of the utility model is, adopted the mode of USB interface and computer to carry out communication, and this unlimited data transmission unit is directly communicated by letter with PC with the plug and play mode, improved the versatility of equipment, has higher utility, economic worth.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
Embodiment
In Fig. 1, the utility model provides a kind of wireless receiver of USB interface, comprises usb interface module 1, master control module 2, radio receiving transmitting module 3, it is characterized in that: usb interface module 1, master control module 2, radio receiving transmitting module 3 connect successively.Master control module 2 is accomplished data acquisition, control usb interface module 1 and the radio receiving transmitting module 3 of observing and controlling object, and the data of gathering are sent to far-end control centre or are transferred to local computer through usb interface module 1 through radio receiving transmitting module 3.Also can realize the RFDC of local computer and far-end control centre.Realize the data communication between local computer, observing and controlling object and the far-end control centre.
Usb interface module 1 is realized by FT245AM; Accomplish usb protocol and parallel I/O protocol conversion, adopt bus-powered mode, the USB power end adds uncoupling anti-jamming circuits such as magnetic bead and electric capacity; The DO of FT245AM-D7 mouth connects the P0 mouth of single-chip microcomputer; With P2 input and output data, WR, RD, TXF and four control ends of RXF connect the P2 mouth of single-chip microcomputer, through the transmission of this control end control data.PWREN connects the INT0 mouth of single-chip microcomputer, in order to judge that FT245AM is in normal operating conditions or suspended state.93C46 is EEPROM, in order to information such as storage equipment sequence number and illustrative words.Master control module 2 adopts the AT89C5l single-chip microcomputer, and operating frequency is 12MHz, and the data of gathering are transferred to local computer through wireless channel far-end control centre or through usb bus.Through the data communication between chip microcontroller local computer, observing and controlling object and the far-end control centre.What radio receiving transmitting module 3 adopted is the NRF401 radio transmitting and receiving chip of NORDIC company, adopts the KSK modulation-demodulation technique, and message transmission rate is 20kbps, need not encode to data.Transmitting power is adjustable, adopts differential antennae, transmit-receive sharing.Consider High-frequency Interference, radio frequency part is done a pcb board separately, and its core is transceiving integrated nRF401 chip, comprises functions such as FSK modulation and demodulation, PLL are synthetic, multi-frequency switching, has characteristics such as low in energy consumption, that peripheral cell is few.
