The invention relates to the field of road traffic speed measurement devices, in particular to a speed limit sign with a speed measurement function. The speed limit signs are embedded in a road surface, n speed limit signs are arranged on a speed measurement road section at equal intervals, each speed limit sign comprises a circular shell with the upper portion not closed, and an annular coil, a wireless communication device, an LED lamp and a storage battery are arranged in each shell; the coil can sense whether a vehicle passes through or not through the change of a magnetic field, the information is uploaded to a user side in real time through the wireless communication device, the vehicle speed is judged according to the time point when the vehicle passes through the two adjacent speed limiting signs, and related responses are made; the upper portion of the shell is covered with a tempered glass plate, and the upper surface of the tempered glass plate is sequentially provided with a speed limiting pattern layer and a wear-resistant anti-skid surface layer from bottom to top. The method is less affected by environmental factors, is accurate in speed measurement, and can provide reliable evidence for road law enforcement; therefore, the night indication capability of the speed limit sign with the speed measurement function is improved.

    本申请涉及道路交通测速装置领域,尤其涉及一种具有测速功能的限速标志。所述限速标志镶嵌于路面内,测速路段等距离设置n个所述限速标志,所述限速标志包括上部不封闭的圆形壳体,所述壳体内设置环形线圈、无线通信装置、LED灯以及蓄电池;所述线圈能通过磁场变化,感应是否有车辆通过,由所述无线通信装置实时上传至用户端,通过车辆经过相邻两个限速标志的时间点,判断车速,并做出相关反应;所述壳体上部盖设有钢化玻璃板,所述钢化玻璃板上表面由下至上还依次设置有限速图案层、耐磨防滑表层。本申请受环境因素影响小、测速准确,可以为道路执法提供可靠证据;可以发光显示,提高了所述具有测速功能的限速标志的夜间指示能力。
