Embodiment Construction

[0061] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0062] Such as image 3 As shown, in the prior art industrial signal data access connection relationship, the high-speed data bus is used to write real-time measurement point data to the memory server group, and any of ZMQ, RabbitMQ, ZeroMQ, JMS, MSMQ, ActiveMQ, Jafka / Kafka can be used A realization.

[0063] The memory server node information table is used to save the memory server measuring point allocation table sig_server_list and the array sig_id_array.

[0064] The data writing scheduler reads the measuring point signal data from the high-speed data bus, and selects the memory server to save the data.

[0065] The memory server is used to store and retrieve data, and its memory allocation graph structure is as follows: figur...

Abstract

The invention relates to an industrial signal data access method based on a fixed-length data block and solves the defects of waste of data extraction resources due to low industrial signal source extraction data utilization rate in the prior art. The method comprises the following steps: constructing a memory server cluster; encoding measuring points on each memory server; receiving data sent by a data high-speed bus; carrying out memory server data receiving and processing; and requesting the server or a client to read the data. The method reduces calculation load of the server in data retrieval, and meets requirement for real-time display of process key data of the client and real-time display of an industrial curve report.

Description

technical field [0001] The invention relates to the technical field of industrial data access, in particular to an industrial signal data access method based on fixed-length data blocks. Background technique [0002] With the improvement of businesses and technologies such as the Internet of Things, cloud computing, and big data, and the promotion of the national "Made in China 2025" strategy, the industrial data center will play an irreplaceable role as the collection, storage, and distribution center of industrial data. In the daily scenarios of industrial applications, it is necessary for the industrial data center to efficiently collect discrete industrial measuring point data signals and retrieve data efficiently to meet the requirements of real-time process data display and real-time curve reports on the industrial site. In order to meet the high-speed access of industrial implementation signals, it is essential to adopt efficient data cache management technology. [...
