The signal filtering amplification type flue pipe temperature monitoring system is characterized in that the signal filtering amplification type flue pipe temperature monitoring system is mainly composed of a sub-station system and a main station system; the sub-station system is composed of a sub-station single-chip microcomputer, a buzzer, a first wireless transmission module, a signal processing unit, a drawing fan controller, a temperature sensor W, and a drawing fan, wherein the sub-station single-chip microcomputer is connected with the buzzer, the first wireless transmission module, the signal processing unit and the drawing fan controller, the temperature sensor W is connected with the signal processing unit, and the drawing fan is connected with the drawing fan controller; and the signal processing unit is composed of a processing chip U, a triode VT2, a polar capacitor C4, a four-order filtering amplifier circuit, a signal receiving circuit, a signal pulse width adjusting circuit and a sampling signal output circuit. The signal filtering amplification type flue pipe temperature monitoring system has advantages of realizing network management on flue gas temperature in the flue pipe of a furnace in a relatively good manner, effectively saving manpower and material resource, and furthermore improving accuracy and reliability in monitoring the flue gas temperature in the flue pipe of the furnace.

Description

technical field [0001] The invention relates to the field of automation control, in particular to a signal filtering and amplifying flue temperature monitoring system based on Internet of Things technology. Background technique [0002] The raw materials used in the carbon plant are mainly petroleum coke and pitch. Under high temperature conditions, the roasting workshop is used to roast the green carbon blocks formed by vibration into qualified cooked carbon blocks. The temperature of the green carbon block during roasting is 200-1200°C. This process will release a large amount of roasting flue gas. The main components of the roasting furnace flue gas are asphalt fume, tar and various combustible dust, and the flue gas outlet temperature is as high as 900°C. During the production process, the flue gas temperature in the flue must be monitored at any time. When the temperature is too high, it must be discharged from the flue in time, otherwise it is easy to cause combustion ...
