Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 As shown, a safe sensor network wireless transceiver module is the WNZG780 series wireless transceiver module. The adopted protocol is IEEE802.15.4. The SPI interface is used to connect the registers, frame buffer, SRAM and AES interface of the WNZG780 series wireless transceiver module module, and it is connected to the SPI port of the MCU as a slave device. SLP_TR is a multi-function pin, its function is related to the current state of AT86RF212, when connected to any IO port of MCU, it can control WNZG780 series wireless transceiver module to sleep or start sending. All interrupt events of the WNZG780 series wireless transceiver module are combined into a single external interrupt signal IRQ, which is connected to the capture port of the MCU or the external mid-range input port. The main clock output of the WNZG780 series w...

Abstract

A safe sensor network wireless receiving and sending module comprises a processor micro control unit (MCU) and a wireless transceiver module, wherein the processor MCU is connected with a corresponding interface of the wireless transceiver module. Compared with an existing communication module, the safe sensor network wireless receiving and sending module has the advantages of being low in power consumption, high in sensitivity and strong in penetrating power. Under the condition of the same transmitted power, the safe sensor network wireless receiving and sending module is stronger in penetrating power, farther in communication distance and better in communication quality than other zigbee transceivers of an ISM frequency band.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a Zigbee-based sensor network wireless transceiver module, in particular to a safe sensor network wireless transceiver module. [0002] Background technique [0003] For a long time, the wireless communication market with low price, low transmission rate, short distance and low power has always existed. Since the emergence of Bluetooth, it has made industrial control, household automatic control, toy manufacturers and other businesses excited. However, the price of Bluetooth has remained high, which has seriously affected the willingness of these manufacturers to use it. During the use of Bluetooth technology, people found that although Bluetooth technology has many advantages, there are still many defects. For the fields of industry, home automation control and industrial telemetry and remote control, Bluetooth technology is too complicated, with high power consumption, sh...
