State feedback monitoring system in activated carbon injection system

Abstract

The invention discloses a state feedback monitoring system in an activated carbon injection system, and relates to the technical field of flue gas treatment of a garbage power plant, a PLC system is connected with a frequency converter and a control instrument through an RS485 mode and communicates based on a modbus rtu communication protocol, when facing multiple instruments and multiple devices, simple line lap joint can be carried out through communication. The connection of hardware can be realized, functions can be quickly modified in software through a programming mode, logic control requirements can be met, and for an activated carbon injection system, adjustability and optimization can be realized; meanwhile, the state and data are presented on the touch screen through the RS485 communication interface in the same way according to the feedback information of the running state of the equipment obtained through communication, so that holes are reduced in a panel of the control cabinet, and the state of the system is directly reflected through the human-computer interface, namely the touch screen. The display in the RS485 communication mode is not only customizable, but also diversified.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment in garbage power plants, in particular to a status feedback monitoring system in an activated carbon injection system. Background technique [0002] With the improvement of the degree of automation, all industries will be inseparable from the pursuit of automation of equipment, monitoring and control of the process, and in the existing control cabinet, there are generally multiple circuits, the main circuit is composed of circuit breakers, contactors The secondary circuit is composed of fuses, intermediate relays, indicator lights, control buttons, emergency stop buttons, knobs, transfer switches, multi-function meters, etc. These will increase a lot of wiring in the cabinet, As well as the wiring of the secondary lines in the cabinet, the difficulty of wiring and the error rate will be increased during the production process, which will reduce the work efficiency. Open buttons, indica...
