Abstract

The utility model provides a wireless data transceiver system, which comprises a main control module, a wireless receiving module, a wireless transmission module and a serial port module, and the main control module is respectively connected with the wireless receiving module, the wireless transmission module and the serial port module. The main control module transmits the data received by the serial port module via the wireless transmission module; if the data received by the wireless receiving module belongs to needed data after being analyzed by the main control module, the data is transmitted by the serial port module, and thereby the conversion between wired data and wireless data is implemented.

Description

Wireless data transceiving system

Affiliated technical field

The utility model relates to a kind of electronic data R-T unit, especially wireless data transceiving system.

Background technology

In industrial environment, the transmission of a lot of data all realizes by wire communication, still because wire communication must connect up, makes troubles under many circumstances, also increases cost to transfer of data.

Summary of the invention

In order to overcome the drawback of traditional cable data transmitting device, the utility model adopts the pass-through mode of wireless data to carry out the wired and wireless data transaction of data.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of wireless data transceiving system, comprise main control module, wireless receiving module, wireless sending module, serial port module, it is characterized in that, main control module respectively with wireless receiving module, wireless sending module, serial port module connects, main control module sends out by wireless sending module by the data that serial port module receives, the data of receiving from wireless receiving module belong to self desired data by the main control module analysis, then forward, realize the conversion of cable data and wireless data by serial port module.

The beneficial effects of the utility model are that it is succinct, easy to use flexible, with low cost to make circuit.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a theory diagram of the present utility model;

Fig. 2 is an electric structure chart of the present utility model.

Among the figure, 1. main control module 2. wireless receiving modules 3. wireless sending modules 4. serial port module.

Embodiment

In Fig. 1, a kind of wireless data transceiving system, comprise main control module 1, wireless receiving module 2, wireless sending module 3, serial port module 4, it is characterized in that, main control module 1 is connected with wireless receiving module 2, wireless sending module 3, serial port module 4 respectively, main control module 1 sends out by wireless sending module 3 by the data that serial port module 4 receives, the data of receiving from wireless receiving module 2 belong to self desired data by main control module 1 analysis, then forward, realize the conversion of cable data and wireless data by serial port module 4.

In Fig. 2, by the CPU of C8051F930 single-chip microcomputer as main control module 1, control Si4432 realizes the transmitting-receiving of wireless data.The Si4432 chip is the EZRadioPRO series radio transmitting and receiving chip of a high integration released of Silicon Labs company, low-power consumption, multiband.Its operating voltage is 1.9～3.6V, and 20 pin QFN encapsulate (4mm * 4mm), can be operated in four frequency ranges of 315/433/868/915MHz; Inner integrated diversity antenna, power amplifier, wake the FIFO that transmits and receive data of timer, digital modems, 64 bytes up, and configurable GPIO etc.The data that main control module 1 is received from the RS232 interface of serial port module 4 in the wireless sending module 3 send Si4432 to and carry out encoding process, and go out through antenna transmission with specific form, after the radiofrequency signal amplification that 2 pairs of wireless receiving modules receive, the demodulation, again data are given the CPU of main control module 1, C8051F930 handles accordingly, and MOSI is used for the Serial Data Transfer Mode from C8051F930 to Si4432; MI-SO is used for the Serial Data Transfer Mode from Si4432 to C8051F930; SCK is used for the Serial Data Transfer Mode on MOSI and MISO line between synchronous C8051F930 and the Si4432; NSEL is as chip selection signal, and is when having only chip selection signal to be low level, just effective to the operation of Si4432.Serial port module have the RS232 interface can realize main control module 1 with PC between communicate by letter, thereby realize forwarding between wireless and the cable data.

Claims

1. wireless data transceiving system, comprise main control module (1), wireless receiving module (2), wireless sending module (3), serial port module (4), it is characterized in that main control module (1) is connected with wireless receiving module (2), wireless sending module (3), serial port module (4) respectively.
