Communication method of manufacturing grid service center and resource nodes

Abstract

The invention relates to a communication method of the manufacturing grid service center and the resource nodes. The manufacturing grid service center and the resource nodes mutually send out the service calling data packets of the standard format and the receiving party sends back the service replying data packets of the standard format so as to realize the communication of both parties. The command head of the standard data packet comprises a command starting symbol, a command word, a command code, a serial number, a source node address and a destination node address. The command body of thestandard data packet comprises related parameters, a check code and a command ending symbol, which are arranged in sequence. Space characters are provided among the items of the command head and thecommand body of the standard data packet, and parameter space characters are provided among the related parameters. The manufacturing grid service center allocates the only node address of the resource nodes; the manufacturing grid service center and the resource nodes realize the service calling in an initiative communication way and a timing communication way; the receiving party obtains the related content according to the analysis of the arrangement order of the data packets so as to check and detect errors of the content, search corresponding services according to the command word and implement the services. The communication method simplifies the data transfer way between the manufacturing grid service center and the resource nodes, ensures the effective and accurate communication ofthe same and facilitates the running of a manufacturing grid platform.

Description

(1) Technical field [0001] The invention relates to the technical field of manufacturing grids, in particular to a communication method between a service center and resource nodes of a manufacturing grid. (2) Background technology [0002] The rapid development of network technology and information technology has brought profound and extensive influence to the manufacturing industry. The network-based manufacturing model is an important feature of modern manufacturing, and it has played a positive role in promoting the improvement of manufacturing capabilities, the development of manufacturing levels, and the improvement of corporate competitiveness. [0003] However, in the application and promotion of networked manufacturing, due to the lack of its own theoretical framework, there are problems such as lack of unified standards, insufficient openness, and poor scalability. On the basis of making full use of the grid standard, the manufacturing grid overcomes the deficiency...

Problems solved by technology

[0006] (1) Although the technicians of each resource node of the manufacturing grid have relatively rich technologies related to the manufacturing industry, they usually lack computer programming ability, especially network programming ability. Therefore, when developing services, it is necessary to define service interfaces, package Resources will spend a lot of time, material and financial resources, resulting in burnout of development willingness and restricting the development of manufacturing grids;

[0007] (2) Due to the arbitrariness of the service interface of each node, the service center needs to analyze and transmit a large number of various types of information such as manufacturing, interaction, and monitoring, which increases the burden on the service center, especially when the number of resources is large. The volume will expand rapidly, greatly affecting the performance of the system;

[0008] (3) When resource nodes are added, changed, decreased, deleted and other service changes, it is necessary to redeploy and communicate with the service center for changes, which has a large workload and generates a large amount of communication traffic

[0009] In short, various tasks scheduling services, login services, resource management services, status monitoring services and other services in the manufacturing grid require the service center to directly provide interfaces for the remote computers of the resource nodes.
