Problems solved by technology

[0002] With the development of industrial automation, data transmission between terminals and the Internet of Things is widely used in home automation, telemetry and remote control, automobile automation, agricultural automation, and medical care. However, the transmission method of data transmission through serial ports can only achieve point-to-point Wired transmission of data, but wireless transmission of data cannot be achieved, resulting in an increase in material costs in data transmission; while the transmission method of data transmission between terminals and the Internet of Things using WIFI, Bluetooth or GPRS / EDGE / 3G modules has realized wireless transmission of data , but still has the disadvantages of high power consumption, high cost, and poor confidentiality, and is not suitable for a large number of applications in the promotion of the Internet of Things. Therefore, it is necessary to provide a data transmission method with low power consumption, low cost, and high confidentiality, and , in wireless data transmission, how to convert wired data signals into wireless signals for data transmission is an important technical problem to be solved

Abstract

The invention provides a Zigbee wireless transmission and conversion device based on RS232 interface, which comprises a Zigbee wireless communication module, an RS232 communication interface module and a Zigbee power supply module located in a sealed shell. The Zigbee wireless communication module comprises a RF communication module and a RF front-end amplifier circuit wherein the RF communication module includes microprocessors and RF transceivers. The RS232 communication interface module comprises a MAX232 power level conversion chip unit and an RS232 interface circuit unit. The RS232 communication interface module is used for inputting the data signal to be sent by an external terminal device to the microprocessor of the Zigbee wireless communication module, processing the data signal and modulating by the RP-front-end amplifier circuit, and transmitting to the Zigbee network via RF transceiver. The RF transceiver is also used to receive a data signal to be received in the Zigbee network and then send it to an external terminal device to realize the data transmission of the wired data signal into the wireless data signal. The invention has the advantage of realizing a low power consumption and a low power consumption of a wireless data signal cost, a high confidentiality of two-way transmissions.
