Zigbee IOT (Internet of Things) module and low-power-consumption control method therefor

Abstract

The invention discloses a Zigbee IOT (Internet of Things) module and a low-power-consumption control method therefor. The IOT module comprises a main chip, an antenna, a matching network, a Balun balancing circuit, a receiving port, and a transmission port. The Balun balancing circuit is connected with the receiving port and the transmission port. The antenna, the matching network and the Balun balancing circuit are sequentially connected in series. Received data is transmitted to the receiving port through the antenna, the matching network and the Balun balancing circuit. Transmitted data is fed to the antenna for transmission through the transmission port, the Balun balancing circuit and the matching circuit. The invention also discloses the low-power-consumption control method for the Zigbee IOT module. The module and method can be used for the design of a single-live-line power supply or battery power supply wireless IOT main control module, and meet the requirement of low power consumption.

Description

technical field [0001] The present invention relates to a wireless internet of things device and its low power consumption control method applicable to ultra-low power consumption such as single live wire power supply and battery power supply, and in particular to a Zigbee internet of things module and its low power consumption control method. Background technique [0002] The wireless network has the advantages of free of connection wires and free from space constraints, but the reliability of the wireless network depends on factors such as power supply mode and anti-interference ability, especially the field wireless sensor network, battery-powered near-field wireless system, smart Home appliances that use single live wire technology as the power supply method for electronic systems, such as single live wire switches, battery-powered door contacts in smart homes, doorbells, RF remote controls, RFID cards, and main control modules for wireless smart systems. The high power ...
