Abstract: An electric vehicle for routing inspection of power transmission lines, includes a body; a running mechanism mounted to the body, comprising a front wheel and a rear wheel connected by a cross beam and rolling on the cable; an obstacle sensor and a cam rotatably mounted to the cross beam, the cam rotating to roll onto the cable after an obstacle is detected on the cable such that the front wheel is raised to a position above the cable, and the cam continuing rolling on the cable after the front wheel passes the obstacle such that the front portion of the cross beam falls back downwards and the front wheel then falls back onto the cable, a hanging seat rotatably hanging to the body and a control device at least partially disposed in the hanging seat and comprising a braking device.

Abstract: A traffic light system includes a traffic light unit and at least one reminding unit. The traffic light unit includes a plurality of traffic lights, a detecting module connected to the traffic lights, and a wireless communication module connected to the detecting module. Each reminding unit includes a central processing unit (CPU) and a signaling module, such as a speaker module connected to the CPU. The detecting unit detects the working statuses of the traffic lights and generates corresponding detect signals transmitted to the wireless communication module, the wireless communication module sends the detect signals to the reminding unit in a predetermined reminding area, the CPU processes the detect signals to obtain the workings statuses of the traffic lights and controls the speaker module to play corresponding audio signals to remind the user.
