本发明涉及工业网络领域，特别是一种工业网络信息获取装置、方法、监控系统及存储介质。The invention relates to the field of industrial networks, in particular to an industrial network information acquisition device, method, monitoring system and storage medium.
背景技术Background technique
应用于工业自动化和处理自动化中的工业通信网络通常被设计成分层结构。图1中示出了一个应用中的工业网络架构。如图1所示，该工业网络包括4个层级：现场层1、控制层2、操作层3和管理层4。当然，有些工业网络中也可有其它的分层方式，例如，包括现场层和控制层；又如，包括现场层、控制层和网络层；又或者，包括现场层、控制层和监控层等。Industrial communication networks used in industrial automation and process automation are usually designed in a layered structure. Figure 1 shows an industrial network architecture in application. As shown in Figure 1, the industrial network includes four levels: field level 1, control level 2, operation level 3 and management level 4. Of course, some industrial networks can also have other layering methods, for example, including the field layer and the control layer; for example, including the field layer, control layer and network layer; or, including the field layer, control layer and monitoring layer, etc. .
其中，现场层主要指包括I/O控制器、执行器、传感器、逆变器等执行各种工业操作的设备网络层下的设备组层，如工业以太网层、现场总线系统(如Profibus，Modbus，……)层下的设备组等。控制层主要指执行各种驱动控制、执行控制、传感器数据获取及处理等控制功能的层。在工业网络领域，控制层一般由一个或多个可编程逻辑控制器(ProgrammableLogic Controller，PLC)实现。PLC是一种数字运算操作的电子系统，专为工业环境应用而设计。它采用一类可编程的存储器，用于其内部存储程序，执行逻辑运算、顺序控制、定时、计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。操作层和管理层主要实现对控制层数据的收集、管理及配置等操作。Among them, the field layer mainly refers to the device group layer under the network layer of equipment that performs various industrial operations such as I/O controllers, actuators, sensors, and inverters, such as the industrial Ethernet layer, field bus system (such as Profibus, Modbus, ...) device groups under the layer, etc. The control layer mainly refers to the layer that performs control functions such as various drive control, execution control, sensor data acquisition and processing. In the field of industrial networks, the control layer is generally implemented by one or more programmable logic controllers (ProgrammableLogic Controller, PLC). A PLC is an electronic system operated by digital operations, designed for industrial environment applications. It uses a type of programmable memory for its internal storage program, executes user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and controls various types of machinery through digital or analog input/output or production process. The operation layer and the management layer mainly realize the collection, management and configuration of the control layer data.
目前控制层的PLC主要有两种实现方式，较常用的一种是专用的硬件产品形式(以下简称硬PLC)，另外一种则是软件PCL形式。软件PLC(SoftPLC，也称为软逻辑SoftLogic)是一种基于PC机或服务器开发结构的仿真硬PLC的可编程逻辑控制系统，它具有硬PLC在功能、可靠性、速度、故障查找等方面的特点，利用软件技术可以将标准的工业PC机或服务器设备转换成全功能的PLC过程控制器。软件PLC综合了计算机和PLC的开关量控制、模拟量控制、数学运算、数值处理、网络通信、PID调节等功能，通过一个多任务控制内核，提供强大的指令集、快速而准确的扫描周期、可靠的操作和可连接各种I/O系统及网络的开放式结构。所以，软件PLC提供了与硬PLC同样的功能，同时又提供了PC机或服务器环境的各种优点。At present, there are mainly two ways to implement the PLC in the control layer. The more commonly used one is the form of dedicated hardware products (hereinafter referred to as hard PLC), and the other is the form of software PCL. Software PLC (SoftPLC, also known as SoftLogic) is a programmable logic control system based on a PC or server development structure that simulates a hard PLC. It has the advantages of a hard PLC in terms of function, reliability, speed, and fault finding. Features, standard industrial PC or server equipment can be converted into a full-featured PLC process controller by using software technology. Software PLC integrates the functions of computer and PLC, such as switch control, analog control, mathematical operation, numerical processing, network communication, PID adjustment, etc., through a multi-task control core, it provides a powerful instruction set, fast and accurate scan cycle, Reliable operation and an open structure that can be connected to various I/O systems and networks. Therefore, the software PLC provides the same functions as the hard PLC, and at the same time provides various advantages of the PC or server environment.
但无论是硬PLC还是软件PLC，其与现场层以及上层操作层和管理层的连接都是通过对应的物理接口来实现的。PLC不会在控制层网络和现场层网络之间进行桥接和路由，这对于数据控制的安全性和鲁棒性非常有好处，但同时也因此很难对现场层设备组进行实时监控和诊断。But whether it is a hard PLC or a software PLC, its connection with the field layer, the upper layer operation layer and the management layer is realized through the corresponding physical interface. PLC does not bridge and route between the control layer network and the field layer network, which is very good for the security and robustness of data control, but at the same time it is difficult to monitor and diagnose the field layer device group in real time.
