Coal conveying monitoring method and system

Abstract

The invention discloses a coal conveying monitoring method and a coal transmission monitoring system. The coal transmission monitoring method includes the following steps that: each set of coal conveying equipment is respectively in connection communication with one field bus branch control device; all branch control devices are grouped according to rules, and each group of branch control devices is in series connection communication with one main control device through a field bus; a plurality of main control devices are in series connection communication with one another through the field bus; and the main control devices are in connection communication with station control devices through repeaters. With the coal conveying monitoring method and the coal transmission monitoring system of the invention adopted, the number of hardware and installation cost can be saved; equipment maintenance cost can be reduced; a user can have high-degree initiative of system integration; the accuracy and reliability of the system can be improved; and the anti-jamming capability of the system can be improved.

Description

technical field

[0001] The invention relates to the field of power plant auxiliary systems, in particular to a coal delivery monitoring method and system thereof. Background technique

[0002] Among the auxiliary systems of the power plant, the coal handling monitoring system has the characteristics of the harshest environment, the most dispersed system, and a relatively large control scale. It uses a large amount of cables and installation accessories, a large amount of installation and debugging, and a lot of maintenance. Current status of the coal transportation monitoring system The main problems are: 1. The environment is harsh, the temperature difference is large, and there is a lot of dust; 2. There are many controlled devices; 3. The scope is wide and the distance is long; 4. The number of cables is large. Our traditional coal handling monitoring system adopts DCS / PLC control, which is also the mainstream at present. Its form is: generally according to the number of ...

Embodiment Construction

[0035] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, the present invention proposes a coal handling monitoring system, including a plurality of coal handling equipment, a fieldbus sub-control device 300 electrically connected to each coal handling equipment, and a plurality of sub-control devices 300 through the field bus serial communication The connected master control device 200, and the station control device 100 connected with multiple master control devices 200 through field bus communication.

[0037] By connecting many scattered coal handling equipment with the sub-control device 300 with field bus function, then the sub-control device 300 is connected and communicated with the main control device 200 through the field bus, and finally the main control device 200 is connected with the station through the field bus. The control device 100 is connected and communi...
