[0020] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0021] Embodiment:

[0022] The loose coupling idea comes from computer systems and is originally used for the design of client / server architecture and then used for the design of the relationship between two or more modules in software engineering design. The loose coupling idea can improve multi-task parallel processing capability, realize load adaptation, isolate attacks on the proxy end and protect the background service, and improve system maintainability. The loose coupling idea is applied to the ship acquisition and processing system to separate the signal input and output from the signal operation and processing module, interconnect through high-speed network, improve the multi-task processing capability of the system, and have the ability of fault reconstruction and maintenance.

[0023] As shown in Figure 1 , it is a loose coupling networked acquisition and processing architecture and system principle diagram. The system is composed of multiple groups of loose coupling acquisition and processing modules {(a1, b1), (a2, b2), (a3, b3), …, (an, bn)}, wherein the IO acquisition module is {a1, a2, a3, …, an}, the operation and processing module is {b1, b2, b3, …, bn}, the number of IO acquisition modules can be different from the number of operation and processing modules, for comparison with tight coupling, the number of two kinds of modules can be designed to be the same, each module is an independent physical module, and is interconnected through high-speed network.

[0024] According to the loose coupling idea, the IO acquisition module ak and the operation and processing module bk are physically independent modules, which are respectively connected to the high-speed switching network and interconnected through the network.

[0025] The embodiment of the present application provides a loose coupling networked acquisition and processing architecture and system for ships, which specifically comprises the following steps:

[0026] Step 1, according to the operation control and management requirements of the ship system equipment, a loose coupling networked acquisition and processing architecture and system is arranged.

[0027] Step 2, the system is composed of a plurality of groups of loosely coupled acquisition processing modules {(a1, b1), (a2, b2), (a3, b3), …, (an, bn)}, wherein the IO acquisition modules are {a1, a2, a3, …, an}, the operation processing modules are {b1, b2, b3, …, bn}, the number of IO acquisition modules is the same as the number of operation processing modules, and the modules are independent physical modules and interconnected through a high-speed network.

[0028] Step 3, for any group of acquisition processing modules ((ak, bk), k = 1, 2, 3, …, n), the IO acquisition module ak and the operation processing module bk are physically independent modules, and are respectively connected to a high-speed switching network and interconnected through the network according to the loose coupling design idea.

[0029] Step 4, for any IO acquisition module ak (k = 1, 2, 3, …, n), a related configuration rule Ak can be defined, including detailed priority and scheduling rules, so that any IO acquisition module ak and one or more of the operation processing modules {b1, b2, b3, …, bn} form a collaboration group, and the number of collaboration groups can reach n (C1n+C2n+C3n+……+Cn-1n+Cnn), and a certain type of collaboration group is (a3, b1, b3, bn).

[0030] Step 5, for any operation processing module bk (k = 1, 2, 3, …, n), a related configuration rule Bk can be defined, including detailed priority and scheduling rules, so that any operation processing module bk and one or more of the IO acquisition modules {a1, a2, a3, …, an} form a collaboration group, and the number of collaboration groups can reach n (C1n+C2n+C3n+……+Cn-1n+Cnn), and a certain type of collaboration group is (a1, a2, an, b1).

[0031] Step 6, for system-level task execution, based on the loosely coupled acquisition modules and operation processing modules, flexible and diverse system-level load balancing strategies and scheduling rules can be designed, compared with the traditional tightly coupled design of only one combination, the loosely coupled acquisition modules and operation processing modules can have up to (C1n+C2n+C3n+……+Cn-1n+Cnn)2 combination cases.

[0032] Step 7, in the case of failure of a certain IO acquisition module or a certain operation processing module, the combination relationship between modules can be flexibly adjusted and reconstructed according to the designed scheduling rules, so as to effectively deal with the failure and ensure the normal execution of acquisition and processing functions. For example, for a certain assistance group (a3, b1, b3, bn), b3 is the optimal cooperation object. When b3 fails, the failure recovery rule can adjust from b3 to b1 for suboptimal cooperation, if b3 and b1 fail, it can be adjusted to bn for bottom-line cooperation, and even if b1, b3 and bn all fail, it can also adaptively adjust the rules to select bk (k≠1, 3, n) which is not in the initial cooperation group and is working normally for emergency cooperation, as shown in the following table. Figure 2 The method of dealing with the failure of a module in another cooperation group is similar.

[0033] Step 8, in order to ensure that the failure recovery rule can be effectively executed when a module fails, the failure recovery rule is deployed on all operation processing modules {b1, b2, b3, …, bn}, and a certain module bk is initially selected as the main monitoring module to monitor the working condition of each module. When bk fails, the main monitoring authority can be transferred to another operation processing module according to the rules.

[0034] The above steps realize the loosely coupled ship networked acquisition and processing architecture and system.

[0035] Those skilled in the art will readily understand that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
