A bus control system based on COV data processing

Abstract

The invention discloses a bus control system based on COV data processing. The bus control system comprises a data modeling service module used for building data modeling service; The COV data processing service module which is used for establishing a COV data processing service, reading a message subscription rule and a COV analysis storage strategy from the data modeling service module, and registering a subscription message on the MQTT bus service module according to the read message subscription rule after the MQTT bus service module starts an MQTT bus service; The communication managementmachine which is used for collecting data of a connected induction device and issuing the collected data to the MQTT bus service module according to an agreed format; The MQTT bus service module which is used for pushing the published data message to the COV data processing service module according to a message subscription rule; And the COV data processing service module which is used for analyzing and processing the data message and storing the data message in a database after receiving the pushed data message.

Description

technical field [0001] The invention relates to the technical field of bus control systems, in particular to a bus control system based on COV (Change Of Value) data processing. Background technique [0002] At present, the industrial Internet of Things is booming, and various applications based on the data collected by the Internet of Things continue to expand. No matter how the application scenarios change, a stable data collection, transmission, and storage system is the cornerstone of building upper-layer applications. The collected data is delivered to the platform from the IoT sensor device, and the traditional socket point-to-point transmission method is adopted. The effect is not ideal in the scenario where there are many collection points, high collection frequency and "fragmented" data. [0003] The MQTT subscription publishing mechanism can meet our needs very well. The communication management machine that implements the MQTT protocol publishes each collected dat...

Problems solved by technology

The messages "pushed" by MQTT are small in size but very large in number. Of course, we can store them all and post-process them through ETL, etc., but it will inevitably lead to a substantial increase in storage costs and maintenance workload; if When we process each piece of data, we will face the dilemma of real-time data and data storage capacity
