A low power consumption internet of things module and its control method

Abstract

The invention discloses a low-power-consumption Internet of Things module and a control method thereof. A CPU (Central Processing Unit) main chip which is provided with an internally arranged RF front end comprises an antenna, a matching network, a high-pass filter HPF, a low-pass filter LPF, a balancing network, a receiving port and a transmitting port, wherein the receiving port is connected with the low-pass filter LPF through the balancing network; the transmitting port is connected with the low-pass filter LPF through a coupling capacitor; the low-pass filter LPF, the high-pass filter HPF, the matching network and the antenna are sequentially connected in series. Meanwhile, the invention discloses a low-power-consumption control method. The CPU is set into a sleep state and is set into a working mode of being waked up through triggering of the RF front end; the front end provided with the RF sleeps and works according to a mode of 10: 1; the front end provided with the RF enters a sleep mode when no valid data is received; and when valid data are received, the CPU is waked up automatically for processing and then enters the sleep mode automatically after the processing is finished.

Description

technical field [0001] The present invention relates to a low-power Internet of Things module and a control method thereof, in particular to an MFSK890 module using the present invention, which is especially suitable for Internet of Things modules with ultra-low power consumption requirements such as single live wire power supply and battery power supply. 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.

Problems solved by technology

The high power consumption of the system and the poor battery life shorten the life of the wireless network; in an electronic system with a single live wire, because the electronic system is connected in series with the load, the high power consumption will cause a large current flowing through the load, which is likely to cause misoperation of the load, such as The large power consumption in the single live wire switch causes the flashing of the load LED light and the slight brightness of the fluorescent light, etc.
