An embodiment of the invention discloses a method and a system for recognizing traffic lights by an automobile data recorder. The method includes acquiring to-be-recognized images captured by a frontcamera of the automobile data recorder; if the to-be-recognized images include traffic light identities is confirmed, recognizing passing indication information in the traffic light identities; providing the passing indication information to on-vehicle users. By the method and the system, the automobile data recorder can have an automatic traffic light recognition function, and the passing indication information of the traffic lights is provided for the on-vehicle users, especially the on-vehicle users with color blindness or color weakness or driving with fatigue, so that traffic safety levelis further improved, and the possibility of accidents is reduced.

A safety system of automobile comprises a video camera shooting unit for obtaining eye information of driver and a computer for receiving obtained eye information. It is featured as setting a detection unit and alarm unit connected with detection unit on computer for sending out alarm by alarm unit when it is detected out that eye-close time of driver is over a preset time by detection unit.

The invention discloses an upper corner treatment method for a large-dip-angle mining work face. An interval construction method is adopted, that is, each time of construction is completed in the weighting interval of the work face. Specifically, two rows of single supporting pillars are erected at the back of an end supporting frame, and a plurality of segmented isolation walls are arranged at the adjoining position of an upper gate road and a goaf in the direction parallel to an upper gate road roadway at equal intervals; a plurality of flexible air bags are installed beside the segmented isolation walls correspondingly and near the side of the upper gate road; the goaf is grouted; roof pre-splitting is carried out at a side thick hard roof of the goaf; the flexible air bags and the single supporting pillars are detached, and upper corner treatment is completed after the roof is collapsed; and construction is conducted circularly until mining of the work face is completed. Compared with the prior art, the upper corner treatment method for the large-dip-angle mining work face has the characteristics of being easy, convenient and fast to construct, low in labor intensity, good in safety and the like, and is particularly suitable for upper corner treatment of an inclined mining work face with the inclination angle of 30-45 degrees or a steeply inclined mining working face.

A control system and method for the locating and communication equipment carried by bus is disclosed, which can used the GPS and GPRS to implement the visualized monitor to buses and provide the real-time running information to central schedule system, such as running state, running route and current position. The real-time communication and interaction between bus and schedule system, automatic processing, analyzing and comparison to acquired data, and the automatic video and audio bus stop report can be performed.
