Description
Technical Field
The invention belongs to the field of passenger information systems in rail transit, and particularly relates to a suspension type rail transit PIS system.
Background
The track traffic has less lines in the initial development stage, and the lines have no transfer relation, the line span is larger, and the influence among the lines is smaller. Therefore, the schemes of the PIS System (Passenger Information System) are not uniform, and in this case, PIS of each line are independent and do not affect each other. However, due to the rapid development of rail transit, the number of routes is increasing, and it is not appropriate to ignore the change of the traffic network from the viewpoint of the routes, and the existing independent PIS has the following problems:
firstly, resource waste: when the existing PIS system is built, each line needs to build mutually independent and complete PIS. This requires a control center of each line to be equipped with a set of independent media editing equipment, and because the editing and manufacturing of information media is technically certain, a certain number of technicians are required to maintain the equipment. Meanwhile, all information in the same wire network is required to be consistent. If the programs are edited and produced independently by each line after being unified, repeated work can be generated, and waste of various software and hardware resources and human resources can be caused.
Second, management difficulties: the PIS with independent lines is difficult to manage and edit the broadcast content uniformly, and the whole network cannot be managed simply and effectively.
Third, the interface is complex: when the existing three-layer PIS structure is built, all lines need to have corresponding interfaces with external information, and all lines need to have good information access conditions, so that the construction cost is increased, and the construction is not beneficial to engineering implementation. In addition, the PIS not only requires a corresponding interface between lines which are transferred with external information, but also a corresponding interface between lines, so that the information of the transfer stations can be effectively synchronized.
Generally speaking, the existing PIS system is relatively independent, unified management cannot be achieved, the number of different interfaces is large, implementation is complex, information transmission is difficult, and each PIS point needs technical personnel to maintain equipment, so that great waste of resources is caused.

Drawings
Other features, objects and advantages of the present application will become more apparent upon reading of the following detailed description of non-limiting embodiments thereof, made with reference to the accompanying drawings in which:
fig. 1 is a diagram of the construction of a suspended track traffic PIS system of the present invention.
Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
In order to facilitate passengers to wait and take a bus, information display equipment for providing information services for the passengers is arranged at the platforms of each station, the passengers can know running information, announcement information, safety matters and the like of the train in time through the display equipment, and meanwhile, the PIS system can play contents such as weather forecast, current news, entertainment programs and the like in the running clearance time of the train.
The main contents displayed to passengers by the PIS system comprise: real-time train arrival dynamic information; some important matters (emergencies, notifications, etc.); broadcasting the information of the television station; advertising information and other desired graphics information; passenger riding advice and city tourism information; real-time weather forecast and socially important information. In addition, the broadcast is set in the vehicle section/parking lot, and can be used for the relevant duty personnel to conduct work command and production scheduling to the jurisdiction area.
For a transfer line in the conventional PIS system, an interface generally has two forms:
firstly, a station interface: and a station interface form is used, transfer line information is interconnected in the station, and the information does not pass through a control console. At this time, the information distribution in this manner does not comply with the station information system rule and related regulations. Because the lines of transfer are mostly built by stages, the difficulty is relatively large when the lines of later-stage construction are unified with the interfaces of earlier-stage construction.
II, a central interface: when using the hub interface format, the information of the transfer lines is only interconnected at the point of the control hub, in order to prevent the first form of interface problem. But the use of interconnected fiber optic cabling is required in the control center, which undoubtedly increases the difficulty of PIS construction. The increase of the lines makes the relationship of the transfer lines more complicated, and the number of interfaces of the lines becomes larger, which is not beneficial to the management of the system.
Therefore, the building of the PIS aims at the global network, a play control center is generally built at the top layer of the system, and the PIS can uniformly manage and control information broadcast in the network by setting rules.
