Embodiment
[0024] Such as figure 1 As shown, the signal preprocessing-based frequency compensation type roaster flue temperature monitoring system of the present invention is mainly composed of a monitoring terminal and a monitoring center wirelessly connected to the monitoring terminal. The monitoring terminal is set up on the production site, while the monitoring center is set up in the office area away from the production site, so the monitoring personnel can know the real-time temperature in the flue of the carbon roaster without going to the production site.
[0025] The monitoring terminal consists of a processor, a first wireless communication module and a frequency compensation module respectively connected to the processor, a conversion module connected to the frequency compensation module, a signal preprocessing module connected to the conversion module, and a signal preprocessing module connected to the signal preprocessing module. It consists of a temperature sensor connected...

The invention discloses a frequency compensation type roasting furnace flue temperature monitoring system based on signal preprocessing. The frequency compensation type roasting furnace flue temperature monitoring system is mainly composed of a monitoring terminal and a monitoring center wirelessly connected with the monitoring terminal, and is characterized in that the monitoring terminal is composed of a processor, a first wireless communication module, a frequency compensation module, a conversion module connected with the frequency compensation module, a signal preprocessing module connected with the conversion module, and a temperature sensor connected with the signal preprocessing module, wherein the first wireless communication module and the frequency compensation module are both connected with the processor; the monitoring center is composed of an upper computer and a second wireless communication module, a display, an alarm apparatus, a keyboard and a storage module which are connected with the upper computer; and the first wireless communication module is wirelessly connected with the second wireless communication module. As the frequency compensation module is arranged, the frequency of temperature signals can be compensated for and can be more stable, and the monitoring accuracy of the frequency compensation type roasting furnace flue temperature monitoring system can be improved.
Description
technical field [0001] The invention relates to the field of carbon roasting, in particular to a frequency-compensated roasting furnace flue temperature monitoring system based on signal preprocessing. Background technique [0002] The raw materials used in the carbon plant are mainly petroleum coke and pitch. Under high temperature conditions, the roasting workshop completes the roasting of the vibration-formed raw carbon blocks into qualified cooked carbon blocks. The temperature of raw carbon block is 200-1200°C during the roasting process, and a large amount of roasting flue gas is released during this process. 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 ov...
