Abstract: An antenna correcting system is provided. The antenna correction system compares amplitudes of antenna signals that are emitted or received respectively by a plurality of antenna units with each other to select one of the amplitudes as target amplitude. The antenna correction system corrects the amplitude of each of the antenna signals according to the target amplitude. As a result, the amplitudes of the antenna signals are the same as each other or approximate to each other. After the amplitudes of the antenna signals are corrected, the antenna correction system compares phases of the antenna signals with each other to select one of the phases as a target phase. The antenna correction system corrects the phase of each of the antenna signals according to the target phase. As a result, the phases of the antenna signals are the same as each other or approximate to each other.

Abstract: A fire extinguishing device is configured to, in response to a location signal from a fire detector: move to a first reference location; detect a fire and generate a thermal image, and calculate a target direction based on a line of sight and the thermal image; rotate such that the line of sight is aligned with the target direction, and detect the fire and generate a first reference image; move in the target direction to a second reference location, and detect the fire and generate a second reference image; calculate a distance to fire and a height of the fire; move to a location within a predetermined range from the fire, move a tube to a spraying position based on the height of the fire, and discharge an extinguishing agent.

Abstract: A platform of a smart security protection integrated system includes a fire extinguishing device, a security notifying device, a communication transmission device, an automatic moving device, and a detecting device. The fire extinguishing device has a fire extinguisher cylinder and a nozzle that is able to target a fire source to spread fire extinguisher agents. The security notifying device is set in the platform and has an infrared night-vision camera for active detection and video recording. The communication transmission device is set in the platform and has a Wi-Fi signal transmitter and a GSM signal transmitter to transmit videos recorded by the security notifying device to relevant emergency personnel. The automatic moving device is set on the exterior of the platform to enable automatic multi-directional movement and automatic obstacle avoidance for the platform.
