Abstract
The utility model discloses a wireless data communication card comprising a processor, a wireless communication module, and a level converting module. The wireless communication module and the level converting module are both connected with the processor. A data buffer is arranged between the wireless communication module and the processor. The level converting module is equipped with a USB interface and is connected with an external PC through the USB interface. The processor is equipped with a RS232 serial port and is connected with the external PC through the RS232 serial port. The wireless data communication card has beneficial effects that an intelligent scoring device is connected with a central processing station through wireless communication, that cables are not required to be laid onsite, and that neatness and the normalization of a judge place are guaranteed.
Description
Technical field
The utility model relates to a kind of address card, particularly relates to the wireless type data communication card.
Background technology
In various evaluations, activities to decide on awards, all need an evaluation intelligence system of carrying out collective evaluation accurately and fast and voting.System mainly is made up of central data treating stations and some intelligent scoring devices, adopts wheel to be the network topology structure of poll.The intelligent scoring device carries out exchanges data by cable and central data treating stations computer, so just need lay communication cable at the scene, and very trouble seems.
The utility model content
The purpose of this utility model namely is to overcome the deficiency of present technology, and a kind of wireless type data communication card is provided, and solving existing address card all is to be connected by cable with central treating stations, pretty troublesome shortcoming when laying at the scene.
The utility model is achieved through the following technical solutions: the wireless type data communication card, comprise processor, wireless communication module and level switch module, described wireless communication module and level switch module all are connected on the processor, be provided with a data buffer between described wireless communication module and the processor, described level switch module is provided with USB interface, level switch module is connected to the PC of outer end by USB interface, described processor is provided with the RS232 serial ports, and processor is connected with the PC of outer end by the RS232 serial ports.
Also be provided with a filter before described data buffer and the wireless communication module.
Be connected with a watch dog monitoring module on the described processor.
Be connected with a signal indicating module on the described processor.
The beneficial effects of the utility model are: adopt wireless telecommunications that the intelligent scoring device is connected to central treating stations, do not need cable laying at the scene, guaranteed the clean and tidy standard in evaluation place.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with embodiment, but structure of the present utility model is not limited only to following examples:
[embodiment]
As shown in Figure 1, the wireless type data communication card, comprise processor, wireless communication module and level switch module, described wireless communication module and level switch module all are connected on the processor, be provided with a data buffer between described wireless communication module and the processor, described level switch module is provided with USB interface, level switch module is connected to the PC of outer end by USB interface, described processor is provided with the RS232 serial ports, and processor is connected with the PC of outer end by the RS232 serial ports.
Also be provided with a filter before described data buffer and the wireless communication module, be used for that the information of accepting is carried out filtering and handle.
Be connected with a watch dog monitoring module on the described processor, its model is X5034.
Be connected with a signal indicating module on the described processor, be used to indicate the working condition of interface.
The EZ-USB FX single-chip microcomputer that processor adopting Cypress company releases in the present embodiment, model is CY7C64601-52NC.
The wireless communication module of present embodiment is adopted the wireless 433/868/915MHz transceiving chip of the monolithic nRF903 of the up-to-date release of Nordic company, this chip adopts the bluetooth core Technology design, having comprised multiple functions such as three sections high-frequency emission and reception, three sections PLL are synthetic, FSK/GMSK modulation and demodulation, multichannel switching, asynchronous communication interface in the chip of 32 pin, is one of the highest unlimited transfer of data product of present integrated level.Transmission speed reaches as high as 76.8Kbps.Adopt the design of low transmitting power, high receiving sensitivity, use and need not licensing, the service range of open ground can reach 1000 meters farthest.
Because the processor operating voltage in the present embodiment is 3.3V, and the power supply that the USB bus provides is 5V, level switch module is selected the conversion of voltage transitions chip MAX882 realization from 5V to 3.3V of a Maxim company for use.
