Abstract
A motion detecting system includes a microwave motion sensor and an MCU. After detecting a motion with a first configuration, the microwave motion sensor is configured to operate with a second configuration for detecting another motion. The MCU is configured to operate in different modes for performing corresponding actions based on whether the microwave motion sensor can detect motions with different configurations, thereby reducing power consumption. The present motion detecting system can determine the type of motions detected by the microwave motion sensor, thereby reducing the false alarm rate.
Claims18
A motion detecting method, comprising:
- a micro processing unit (MCU) operating in a first mode before receiving a first notice signal;
- a microwave motion sensor operating with a first configuration and sending the first notice signal to the MCU after detecting a first motion with the first configuration;
- after receiving the first notice signal, the MCU operating in a second mode for performing a first action and sending a first configuration signal to the microwave motion sensor for instructing the microwave motion sensor to operate with a second configuration;
- the microwave motion sensor operating with the second configuration determining whether a second motion is detected within a first predetermined period after receiving the first configuration signal;
- in response to the second motion being detected within the first predetermined period, the microwave motion sensor continuing to operate with the second configuration and sending a second notice signal to the MCU for instructing the MCU to perform a second action;
- the MCU determining whether the second notice signal is received within the first predetermined period;
- and
- in response to the second notice signal not being received within the first predetermined period, the MCU sending a second configuration signal to the microwave motion sensor for instructing the microwave motion sensor to operate with the first configuration and the MCU switching to operate in the first mode, wherein:
- the microwave motion sensor performs a slow-speed motion detection or a low-frequency motion detection when operating with the first configuration;
- the microwave motion sensor performs a fast-speed motion detection or a high-frequency motion detection when operating with the second configuration;
- and
- the MCU consumes less power when operating in the first mode than when operating in the second mode.
