Method, system and signal fusion device for implementing bus signal preferential application

Abstract

The present invention discloses a method, a system and a signal fusion device, wherein priority application of a bus signal can be realized. A signal acquisition board and the signal fusion device are additionally arranged between vehicle detecting equipment and a teleseme, the signal fusion device pretreats and weighting-processes various priority application signals, and transmits the signal which is processed to the teleseme; meanwhile, an up transformat and a down transformat are arranged between the signal acquisition board and the signal fusion device, thereby being convenient for transmission and processing of the signal. By adopting the present invention, the request for the teleseme and the processing hardness are reduced to the greatest extent, the processing capability and the efficiency of priority application of the bus signal are enhanced, and the reliable and efficient transmission of the bus priority application signal is ensured.

Description

technical field [0001] The invention relates to bus signal management technology, in particular to a method, system and signal fusion device for realizing priority application for bus signals. Background technique [0002] As the urban population becomes more and more dense, the condition of urban public transport has become a major factor affecting people's living standards. The public transport priority mechanism currently proposed can be divided into road priority and signal priority in form. Among them, road priority refers to the special roads planned for public transport vehicles for their priority use. Although this method improves the road quality of public transport vehicles to a certain extent However, due to the lack of delineation of priority lanes at intersections and the fact that priority lanes do not constitute a complete network system, the expected effect cannot be exerted to a large extent. Vehicles and social vehicles are completely mixed together, which...

Problems solved by technology

[0014] 3) Priority application for intersection signals is complicated

[0016] From the above situation, it can be seen that with the increasing traffic pressure, there are obvious deficiencies in the existing bus priority system: on the one hand, there is no reasonable preprocessing of the priority application signal, but the priority application signal is directly sent to the signal It not only greatly increases the configuration work of the signal terminal, but in some cases may cause a conflict of priority signals at the signal terminal, which to some extent interferes with the normal operation of the signal terminal

On the other hand, there is no priority signal transmission system to meet the priority needs of buses at any intersection

The existing bus priority signal application mechanism does not fully consider the arbitrariness of intersections and the complex situation of coexistence of multiple bus priority applications, and has not established a complete set of priority application signal description methods, nor has it resolved multiple priority application signal conflicts problems, and cannot meet the needs of bus priority in complex situations
