Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] As shown in the figure, the interactive online monitoring method for coal-fired boilers, the method steps are as follows:

[0021] (1) First of all, various sensors 2, feed water flowmeter 8 and coal-fired metering device 9 are installed on the boiler body 1 on site to realize reliable collection of boiler operating parameters; the collected signals are divided into variable signals that need to be installed with sensors, including : Feed water hardness, steam pressure, steam temperature, feed water temperature, ambient temperature, exhaust gas temperature, exhaust gas oxygen content, feed water flow rate and coal consumption; and status signals received from the boiler operation control cabinet 10, including: blower start Stop, current, voltage, high water level, low water level and comprehensive alarm;

[0022] (2), the collected signal data i...

Abstract

The invention relates to a coal-fired boiler interactive online monitoring method. The coal-fired boiler interactive online monitoring method includes the steps that various sensors, a feed water flow meter and a coal-fired metering device are installed on a boiler body on the site; acquired signals are divided into variable signals of the sensors needing installing and status signals; acquired signal data are connected to a data acquisition unit in an interactive control cabinet through a cable, digital-analog signal conversion is conducted through the data acquisition unit, the data are transmitted to the internet through a wireless network transmission terminal, remote data transmission is achieved, and the signal data are remotely transmitted to a computer for monitoring through a network; a mathematical model is built through the computer for monitoring to process the signal data, and online computing information is acquired. The coal-fired boiler interactive online monitoring method has the advantages that information and an operating boiler can be online monitored in real time, the man-machine conversation function can be achieved through a touch screen additionally arranged on the on-site control cabinet, a fireman can know the actual operating status of the boiler on the site, operation is optimized, and operating parameters of the boiler are optimal.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of coal-fired industrial boilers, and more specifically relates to an interactive on-line monitoring method of coal-fired boilers. Background technique [0002] The boiler remote monitoring system can log in through the network, view the remote data in real time, and effectively monitor the boiler operation. The real users of the boiler are the front-line boiler workers, and the original system has no display equipment on site. Therefore, the real-time remote monitoring data of the boiler staff cannot be seen, and the actual operating status of the boiler cannot be effectively grasped. Based on this, an interactive boiler monitoring system is proposed, through man-machine dialogue, so that the boiler staff can grasp the actual operation status of the boiler on site. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior ar...
