The invention discloses an intelligent traffic lamp control system based on an opening community and its control method. The intelligent traffic lamp control system comprises a management center; a database of the management center is stored with resident information and its vehicle information of the community; an upper machine of the management center is stored with information applied for driving to the community and authorized to allow to drive in the community; the upper machine is in communication with a mobile terminal, and used for processing the information sent by the mobile terminaland determines if the vehicle is authorized to drive into the community by referring to the vehicle information; the upper computer is in communication with an intelligent traffic lamp control systemof the community and a road lamp system; the upper computer has two working modes which include a normal working mode and a night working mode; the upper compute judges the working mode that it locates through reading the system time. Through using the night working mode and the normal working mode, the opening community undertakes the traffic task while guarantees the nighttime rest quality of residents in the community.

The invention relates to an intelligent lawn mower and a control method thereof. The intelligent lawn mower is provided with a shield used for protecting life bodies. The intelligent lawn mower comprises an induction device used for inducting intensity of outside light rays and sending out induction signals, and a control device used for receiving and processing the induction signals sent by the induction device so that the shield can be opened or closed according to the induction signals. According to the intelligent lawn mower, the induction device is arranged to induct the outside light rays and sends the induction signals to the control device, and the shield is opened or closed according to the intensity of the outside light rays. At night, the induction device does not induct the outside light rays or induces the weak outside light rays, the shield is closed, and the intelligent lawn mower enters a night working mode and can cut grass on boundary lines of a lawn. Due to the fact that at night, people, animals and other life bodies have few activities, the hidden dangers of cutting the life bodies by the intelligent lawn mower without the shield are reduced.
