Anti-blinding security monitoring device for tunnel

Abstract

The invention discloses a tunnel anti-blinding safety monitoring device, which includes a main controller, and is characterized in that: the main controller is electrically connected with an optical fiber coupler, a signal amplifier, a double closed-loop PID circuit, a three-stage LED lamp and Liquid crystal display screen; the input end of the optical fiber coupler is connected to the signal conversion output end of the temperature and humidity sensor, dust concentration detector, and gas sensor through an optical cable, and the output end of the signal amplifier is electrically connected to the PWM port of the main controller; The three-phase output terminals of the double-closed-loop PID circuit are electrically connected to the BLDCM stator three-phase winding, and the BLDCM output terminals are connected to the ventilation fan blades. The invention performs well during use, the system control is stable, and the brightness of lights in the tunnel can be automatically adjusted according to the tunnel depth and sunlight intensity, effectively avoiding the problem of visual blindness when entering and exiting the tunnel, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the related technical field of tunnel safety early warning, in particular to a tunnel anti-blinding safety monitoring device. Background technique [0002] Tunnels are one of the important sections of modern traffic roads. Tunnels not only solve the problem of road and railway detours, but also bring different driving experiences to people traveling. The tunnel is built on the mountain and passes through the mountain. It has a relatively closed driving environment. Environmental factors such as temperature, humidity, odor concentration, and light intensity inside the tunnel are quite different from those outside the tunnel. The driver has brought a lot of trouble, and the difference in light entering and exiting the tunnel may also cause short-term visual blindness of the driver, which may cause traffic accidents such as car accidents. Therefore, there is an urgent need to design an intelligent device for detecting the environ...
