The invention discloses a multi-stage signal-enlarged type flue temperature monitoring system based on the Internet of Things technology. The multi-stage signal-enlarged type flue temperature monitoring system is characterized by mainly comprising a substation system and a master station system, wherein the substation system comprises a substation single chip microcomputer, as well as a buzzer, a first wireless transmission module, a signal processing unit and an exhaust fan controller which are all connected with the substation single chip microcomputer, a temperature sensor W connected with the signal processing unit, and an exhaust fan connected with the exhaust fan controller; the signal processing unit consists of a treating chip U, a triode VT2, a polar capacitor C4, a two-stage resistance-capacitance coupling amplification circuit, a signal receiving circuit, a signal pulse width adjusting circuit and a sampling signal output circuit. According to the multi-stage signal-enlarged type flue temperature monitoring system, network management of the temperature of flue gas in a calcinator flue is better realized, manpower and material resources are effectively saved, and the accuracy and the reliability of monitoring of the temperature of flue gas in the calcinator flue are improved.
Description
technical field [0001] The invention relates to the field of automation control, in particular to a signal multi-stage amplification 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...
