The invention discloses a tramcar prefabricated track beam and a construction method. The tramcar prefabricated track beam comprises an upper panel and a lower panel which are parallel to each other.At least two supporting portions are arranged between the upper panel and the lower panel, and the gap between every two adjacent supporting portions is larger than the width of the corresponding supporting portions. During construction, steel bars are firstly manually knitted into reinforcement cages matched with the upper panel, the lower panel and each supporting portion; meanwhile, a mold is set up; then the multiple reinforcement cages are placed into the mold and are fixed into a whole; and finally, prepared concrete is guided into the mold, and vibration leveling and forming are achieved. By means of the application of the tramcar prefabricated track beam and the construction method, the tramcar track beam can be prefabricated, the requirements of different specifications can be met, and pavement and manufacturing of different road conditions can be met.

The invention discloses an initial positioning system for a tram, the initial positioning system includes an on-board host on the tram and a tram positioning server in the background, the initial positioning system for the tram also includes sensors arranged on the tram track equipment, a receiving antenna for receiving information of the sensor device, and an activation terminal, the receiving antenna includes a first receiving antenna (1) and a second receiving antenna (2) respectively arranged at both ends of the tram head, and the activation terminal includes The first activating end (7) and the second activating end (8) respectively arranged at the two ends of the trolley car, the present invention effectively improves the positioning accuracy of modern trams during initialization, and at the same time through reasonable arrangement of trackside equipment, it can Quickly determine the initial running direction of the tram.

The invention discloses a method for organizing a waiting area at a tram crossing, in which two tram tracks (1) in opposite directions are arranged in the center of the four east, south, west and north roads intersecting at the crossing, and The one-way occupied road width of the tram is 4m; the steps are as follows: first calculate the shortest distance ΔD between the sideline C1 of the motorway (2) and the arc C2 of the tram track (1); then, determine according to the value of ΔD The type of the intersection, if ΔD≥5.75m, the intersection is a spacious intersection; if not, the intersection is a cramped intersection; Intersection traffic strategy. The application of the invention can effectively improve the traffic efficiency and increase the utilization efficiency of the intersection shared by trams and motor vehicles.

The invention discloses a track fault detection method and system based on infrared thermal imaging and computer vision. The steps of the method are: the unmanned aerial vehicle carries out tram track image acquisition; the ground station receives high-definition camera image data and performs image preprocessing; The darker area inside and the brighter area outside the groove are segmented twice with multi-threshold orbital area, and the orbital area is segmented according to the distance characteristics adjacent to the brighter and darker area, and the orbital image is extracted; the infrared thermal image is grayscaled, and the relative The temperature difference method extracts the high-temperature area on the track; the preprocessed image is superimposed on the track detection window, the mask is used to obtain the region of interest, the edge closure judgment and filling of the region of interest are performed to obtain a connected region, and the connected region is screened to obtain a suspected foreign object on the track; The foreign matter is input into the BP neural network for identification, and the foreign matter classification result is obtained. The invention performs real-time identification and temperature detection of foreign matter on the track, reduces the accident rate of the track traffic, and improves the running safety of the tram.

The warning device (12) includes a warning light mechanism (16), that is configured so as to emit a flashing strobe light (20) that flashes at a frequency that is higher than 10 Hz.
