Embodiment Construction

[0030] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0031] figure 1 It is a working schematic diagram of the present invention in the field bus intelligent monitoring and diagnosis system. exist figure 1 Among them, the field bus intelligent monitoring system of the present invention adopts the "one-to-four" mode, and the fault diagnosis communication module is used as the communication core of the system, which ensures the storage, upload and display of the data collected by the analysis module. When the monitoring system is working, each communication module can be connected in series with at most 4 analysis modules as a group, and each group of modules can cover 4 Profibus bus network segments. The analysis module collects bus data and uploads it to the communicat...

Abstract

The invention discloses an embedded Web server Profibus fault diagnosis communication module. The module comprises a control chip, an external storage unit, a power supply unit, a backboard bus communication interface and an Ethernet communication interface. The control chip is responsible for storing, analyzing and packaging collected data, establishing a Web server and realizing online update of firmware or IP addresses. The external storage unit records communication fault information. The power supply unit supplies power to a board card. The backboard bus communication interface and the Ethernet communication interface are responsible for communication with the external. According to the module, the collected data is uploaded online based on a TCP / IP protocol; the Profibus system can be debugged and maintained conveniently by workers at establishment and operation stages; and the data basis is provided for factory level analysis, control and decision. The module is applicable to power plant Profibus monitoring and can be extensively applied to more bus monitoring fields.

Description

technical field [0001] The invention belongs to the technical field of electric power monitoring, and relates to a communication module used in a field bus monitoring and diagnosis system of a thermal power plant, and is especially suitable for a field communication module requiring remote intelligent monitoring through an Ethernet. Background technique [0002] Fieldbus is an industrial data bus that has developed rapidly in recent years. It mainly solves the digital communication between field devices such as intelligent instruments and meters, controllers, and actuators on the industrial scene, as well as the communication between these field control devices and advanced control systems. Information transfer problem. Among the existing bus standards, Profibus field bus is a field bus standard suitable for power generation enterprises, and is widely used in the field bus system of thermal power plant units in my country. [0003] However, during the debugging and operatio...
