The invention discloses a highway height limiting monitoring device. The highway height limiting monitoring device comprises two poles, an
infrared transmitter, an
infrared receiver, an
infrared camera,
wireless transmission equipment and a host. The two poles are arranged on the two sides of a road of a height limiting highway, the infrared
transmitter is installed at the limited height of the first pole, the infrared
receiver is installed at the corresponding height of the second pole, the infrared camera is installed at the position, on the rear side of the first pole, of the roadside, the host and the
wireless transmission equipment are installed at the corresponding positions of the first pole, and the host is used for controlling the infrared
transmitter, the infrared
receiver, the infrared camera and an infrared transceiving device to work. The infrared transceiving device is used for
monitoring height-exceeding vehicles, the camera is used for shooting
license numbers, a
wireless communication module is used for sending information to a terminal
processing system, and the host is used for conducting uniform control on the devices. By the adoption of the highway height limiting monitoring device, the unattended function and round-the-
clock guard can be achieved, and the highway height limiting monitoring device is safe, reliable, economical and practical.
