Problems solved by technology
In the current domestic urban rail transit signal system, manual guarding is generally used to ensure the safe passage of trains at intersections. When a train passes through an intersection, the information exchange between the on-board controller, the operation dispatching center, and the intersection Need to rely on loop and track circuits, and no real-time communication between the three

Embodiment Construction
[0031] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:
[0032] to combine figure 1 Preferred embodiment is described, a kind of streetcar intersection controller system, it comprises:
[0033] On-board controller, set on each tram;
[0034] A wireless access point is arranged at each intersection, and a communication network of the intersection controller system is established based on this; when a tram enters the coverage area of the wireless access point, the on-board controller accesses the communication network;
[0035] Transmitters, arranged at a distance from the intersection on the track;
[0036] The receiver is installed on each tram and communicates with the on-board controller; when the receiver is close to the transmitter, it transmits a signal to the on-board controller;
[0037] Traffic signal controllers are installed at each intersection to provide...

The invention discloses an intersection controller system of a tramcar. The intersection controller system comprises a carborne controller, a wireless access point, a transmitter, a receiver, a traffic signal controller, an operation dispatching center and an intersection controller. Information interaction with the traffic signal controller, the operation dispatching center and the carborne controller is realized through the intersection controller so as to ensure safety priority pass of trains at intersections. Compared with the prior art, the system has the advantages that artificial attendants are not required, and human input is reduced; real-time information interaction among the carborne controller, the operation dispatching center and the traffic signal controller can be realized, and each device is allowed to clearly know the state of the current intersection; the operation dispatching center has highest priority, and artificial priority and artificial request cancellation can be realized; a loop line and a track circuit are omitted, and equipment number and cost are reduced.
Description
technical field [0001] The invention relates to an urban rail transit signal system, in particular to an intersection controller system for trams. Background technique [0002] With the acceleration of China's urbanization process, the urban population is increasing rapidly, and the urban rail transit system with high safety is an effective way to solve the pressure of public transportation in large and medium-sized cities. As the command center of urban rail transit operation, the traffic signal control system is an important guarantee for the safe, reliable and efficient operation of urban rail transit. In the current domestic urban rail transit signal system, manual guarding is generally used to ensure the safe passage of trains at intersections. When a train passes through an intersection, the information exchange between the on-board controller, the operation dispatching center, and the intersection Need to rely on the loop and track circuit, and real-time communicatio...
