Embodiment

[0032] The main purpose of the present invention is to improve the throughput under the same resources on the basis of the traditional data bus, so as to solve the problems caused by the growth of rail transit data, and at the same time ensure message persistence and realize flexible message processing. At the same time, it meets the two requirements of each business system for message order and disorder.

[0033] In order to meet the requirements of the rail transit system, the data bus needs to support two message engine models at the same time: the message queue model and the publish / subscribe model. Data bus architecture figure 1 shown. Based on this model, figure 2 For the message queue model, image 3 It is a publish / subscribe model, which will be introduced separately below.

[0034] Such as figure 2 As shown, the message queue model provides message transmission services based on queues, and is mostly used for inter-process communication and inter-thread communi...

Abstract

The invention relates to a cloud-based rail transit integrated data bus system communication method and system, and the method specifically comprises the steps of maintaining a theme data structure which comprises at least one partition data structure, wherein the partition data structure is a message sequence with a sequence, the message is a data structure used for transmitting information, andwherein the partition data structure has a unique partition number in the theme data structure to which the partition data structure belongs, and the message has a unique message number in the partition data structure to which the message belongs; and enabling the producer of the message to transmit the message to the corresponding theme data structure, so that all consumers subscribing the themecan obtain the message from the theme data structure. Therefore, the invention has the following advantages: 1, low delay is realized while the throughput of the data bus is improved; 2, through message persistence, flexible message processing is realized; and 3, various requirements of message orderliness, message disorder and the like are supported.

Description

technical field [0001] The invention relates to a communication method and system, belonging to the technical field of rail transit, in particular to a cloud-based rail transit comprehensive data bus communication method and system. Background technique [0002] In the rail transit industry, the informatization of production and operation equipment and systems continues to advance, resulting in the continuous expansion of the amount of data generated by daily operations, resulting in a large amount of structured, semi-structured, quasi-structured and unstructured data. More and more application systems are developing towards integration and large-scale integration. More and more systems need to exchange and integrate data. At present, there is no one that provides better mass and real-time Therefore, the technology of data exchange services cannot realize real-time transmission of data buses across business systems and smooth data exchange. [0003] The existing comprehensi...
