Patent ID: 7978052

Claim:
A microwave control system being applied to control a working system to execute at least one predetermined assignment, and comprising: a microwave control unit, comprising: a microwave illuminator for sending a microwave signal; a first micro control unit; and a first wireless signal transceiver coupled with the first micro control unit; a control card, comprising: an antenna assembly for effectively receiving the microwave signal within an effective triggering region, and generating a first wake-up signal in accordance with the microwave signal; a second micro control unit coupled with the antenna assembly, being waked up from a first sleep mode to enter a first awake mode after receiving the first wake-up signal, and generating a first control signal under the first awake mode hereafter; a second wireless signal transceiver coupled with the second micro control unit, so as to send out a first control signal; a passive control unit comprising: a third micro control unit coupled with the first micro control unit and the working system; and a third wireless signal transceiver for receiving the first control signal and transmitting the first control signal to the third micro control unit; wherein the control card reflects a reflection signal to transmit a reflection signal to the first wireless signal transceiver, the first micro control unit transmits a second wake-up signal to the third micro control unit after the first wireless signal transceiver receives the reflection signal to make the third micro control unit wake up from a second sleep mode to enter a second awake mode, and further to make the third micro control unit transmit a second control signal to the working system, so as to control the working system to execute the predetermined assignment.
