Embodiment 1

[0044] The invention provides a priority control method for trams passing through crossings, which is applied to a priority control system for trams passing through crossings. The system includes a crossing priority control cabinet and a road traffic signal control machine, figure 1 It shows the flow chart of Embodiment 1 of the priority control method for trams passing through intersections in the present invention, and the method includes:

[0045] Step S101: the intersection priority control cabinet judges whether a priority request is received;

[0046] If there is a tram going through the intersection, it will send a priority request to the intersection priority control cabinet, and the request will pass through first, so as not to affect the passage of other social vehicles.

[0047] Step S102: If the first priority request of the first tram is received, the first priority request is sent to the road traffic signal controller, the first route of the first tram is arranged,...

Embodiment 2

[0061] image 3 shows the flow chart of the method of this embodiment, corresponding to figure 1 ,Also includes:

[0062] Step S105: When the priority control cabinet at the intersection does not receive a priority request, control the display state of the special indicator light for trams to remain in the prohibited state.

[0063] When there is no tram to pass through the crossing, the priority control cabinet at the crossing controls the special indicator light of the tram to display "no passage", so that social vehicles can pass through the crossing.

Embodiment 3

[0065] Corresponding to Embodiment 1, processing the first priority request specifically includes:

[0066] The road traffic signal control machine judges whether the phase corresponding to the first priority request is open according to the light color information of the traffic signal light, and if it is open, the road traffic signal control machine sends the first priority confirmation information to the intersection priority control cabinet;

[0067] After the intersection priority control cabinet receives the first priority confirmation information, it controls the display state of the special indicator lamp for the tram to be set to the state of allowing traffic;

[0068] After the intersection priority control cabinet receives the first passing route information sent after the first tram passes through the route, it controls the display state of the special indicator light for the tram to be set as a traffic prohibition state;

[0069] After the intersection priority co...

Abstract

The invention discloses a priority control method and a priority control system for passing of a tramcar at an intersection. The system mainly comprises an intersection priority control cabinet and a road traffic signal control machine. When the intersection priority control cabinet receives a priority request of a first tramcar, a route of the first tramcar is arranged and locked. When tramcars of the other lines need to pass the intersection at the same time, a driver can send a priority request with an unlocking command to ground control equipment if the phase requested by a second tramcar is located at a green light state. The intersection priority control cabinet receives the priority request with the unlocking command of the second tramcar and judges whether an unlocking condition is satisfied or not, the current route is unlocked if the unlocking condition is satisfied, a route of the second tramcar is arranged, the priority request of the second tramcar is processed at the same time, otherwise, the priority request of the first tramcar is processed. The scheme disclosed by the invention can carry out effective priority control on a circumstance that one or more tramcars pass the intersection, thereby ensuring the running efficiency of the tramcars.

Description

technical field [0001] The invention relates to the field of rail vehicle control, in particular to a priority control method and system for trams passing through intersections. Background technique [0002] With the in-depth development of economic globalization and the continuous improvement of people's living standards, people pay more attention to the pollution caused by automobile exhaust to the environment and the damage to their health. In this case, modern trams came into being, not only in Europe It has been widely used, and cities such as Suzhou, Shenyang, and Guangzhou in my country are also planning and building trams one after another. Trams run on urban roads, and there are conflicts with other social vehicles at level crossings. [0003] When a single line passes through a level crossing, the general strategy is to combine the release time of traffic lights and the arrival time of trams, and consider the impact on other social vehicles at the intersection, giv...
