Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traffic sign equipment, in particular to a flip plate type variable traffic sign and working method. BACKGROUND

[0002] Traffic signs are road facilities that convey guide, limit, warning or indication information through words, numbers or symbols. In traffic signs, it is important to implement traffic management and ensure road traffic safety and smoothness by setting up eye-catching, clear and bright traffic signs. Traffic signs have various types and can be distinguished in various ways: main signs and auxiliary signs; movable signs and fixed signs; illuminated signs, light-emitting signs and reflective signs; and variable information signs reflecting changes in driving environment. The above-mentioned types of traffic signs can be generally divided into fixed signs and electronic variable signs. The information on fixed signs is fixed, and the signs are installed in locations that do not need to be changed throughout the year. When changes are needed, the old sign needs to be removed and discarded, and a new sign needs to be installed. Such signs have low cost but are difficult to reuse, resulting in significant waste. LED electronic signs are generally installed in locations where the identification information needs to be changed frequently, such as variable lanes. By controlling the pattern of the matrix LED, the identification information on the electronic sign can be changed. Such signs need to be powered for a long time, resulting in energy waste. When not powered, the screen is black, which can cause incorrect guidance.

[0003] Currently, there are also flip plate type variable signs, such as the flip type variable speed limit light-emitting road traffic sign disclosed in patent application No. 202022044996.X. The multi-sided cylinder is flipped by a motor, like a whole window blind, to display different speed limit identification information. The number of information displayed by such signs is also limited (as shown in the figure, there are only three types of identification information for three prisms), and the sign needs to be flat. In addition, LED constant display is also provided, which also has the problem of high energy consumption. LED is an active light-emitting method, which is too bright in a completely dark background at night and the characters are easily blurred in strong light during the day. Therefore, there is an urgent need to design a flip plate type variable traffic sign and working method to achieve sign recognition through retroreflective reflection, with the same effect as ordinary traffic signs, to solve the problems of existing variable information sign recognition, non-reusability and high energy consumption.
