Problems solved by technology

At present, most dumpers are still controlled by PLC. The software is limited by the number of I / O points, the hardware is aging and spare parts cannot be purchased, and the ladder diagram is used for programming. It is difficult to complete some complex calculations, such as analog calculations. Intuitive, programming is more complicated and troublesome; PLC modules are upgraded quickly and expensive, and are not easy to purchase, resulting in expensive upgrades for the entire set of equipment
Accident handling is relatively complicated, and functions such as accident recall, historical trend, and alarm are insufficient. It is impossible to effectively and quickly find the fault point under the accident state. Often, the accident is not handled in time and the cause is not clear, etc., resulting in some train delays and equipment. Hidden dangers such as disease operation

Embodiment Construction

[0038] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] ginseng figure 1 As shown, this embodiment provides a DCS control system for a tilting dumper, which is characterized in that it includes a controller, a control cabinet, and an industrial computer. The DCS control system mainly includes 1 pair of controllers, 2 control cabinets, 2 sets of industrial computers, each control cabinet contains four power supply modules (for internal and external loop power supply), 2 communication modules and the required I / O modules (including switching value and analog value modules). Data exchange is realized by means of Ethernet communication through twisted pair, and data exchange with the industrial computer is realized through ...

Abstract

The invention relates to a DCS (Distributed Control System) of a side-tipping car dumper. The DCS comprises a controller, a control cabinet and an industrial personal computer. The DCS is adopted, and the disadvantages of a PLC device are eliminated through the advantages of algorithm, logic identifiability, accident recall, alarm, historical trend, picture friendliness, expandability and the like of a DCS system; and through the DCS, worker operation and equipment fault points can be quickly locked, logics and pictures can be downloaded without shutdown, the labor amount of workers is greatly reduced, the fault processing time is reduced, the investment of funds such as fault processing and train delay cost is saved, and a guarantee is provided for staff reduction and efficiency improvement of enterprises.

Description

technical field [0001] The invention belongs to the technical field of thermal power generation, and in particular relates to a DCS control system for a tilting dumper. Background technique [0002] The side tilting dumper means that there is a certain eccentric distance between the vehicle and the rotor, and the vehicle is lifted by the cantilever of the rotor. The coal is dumped in the coal receiving hopper on one side. It is characterized by relatively large dead weight, large power consumption, and relatively low civil construction costs. smaller. [0003] At present, the CFH-ⅡA side tilting dumper is suitable for large-scale thermal power plants, chemical plants, cement plants, ports, coking plants, sintering plants in the metallurgical industry, etc. to dump bulk materials such as coal, ore, and yellow sand. railroad gondola. CFH-ⅡA dumper is mainly composed of transmission device, end plate, clamping mechanism, trailer beam, platform, main bearing assembly and other...
