Multimedia information processing method, device and passenger information system

Abstract

The present invention proposes a multimedia information processing method, device, and passenger information system, wherein the system includes: a software-as-a-service SaaS data center, multiple ground equipment terminals, and at least one operation center; the operation center communicates with the SaaS data center for Obtain the input line plan, and send the media operation information required for executing the line plan to the SaaS data center; the SaaS data center communicates with multiple ground equipment terminals for data processing of the media operation information, and obtains the data of each ground equipment terminal. Media operation plan, and send the media operation plan to the corresponding ground equipment; the ground equipment is used for multimedia display according to the media operation plan. It can realize that when the business function of the operation center is changed, only the software code needs to be modified in the SaaS data center, which is easy to operate and has high scalability.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a multimedia information processing method, device and passenger information system. Background technique [0002] In the urban rail transit industry, Passenger Information System (PIS) is used to provide passengers with diversified multimedia information services, such as train operation information, network operation information, convenience information or emergency evacuation information. [0003] At present, PIS has two operation and management modes: "one line, one center" and "multi-line shared line center". Among them, the single-line operation and management model of "one line, one center" is: independent bidding, construction and operation of PIS for each line, and development and design are required from software to hardware. The control systems of different line control centers are not interconnected. When the business function changes, it needs to be re-deploye...

Problems solved by technology

Therefore, once the business function changes, the control system code still needs to be redesigned, making it difficult to expand flexibly

[0005] In the PIS under the single-line operation mode and the network operation mode, once the business function is added or changed after the construction is completed, the adjustment is relatively difficult and the scalability is not high, which is not conducive to the long-term construction and development of the PIS
