The invention discloses a temperature acquisition device and a
bed temperature
visualization system and method.The temperature acquisition device comprises a high-temperature camera device and a
bed temperature
thermocouple, the high-temperature camera device is integrated on the
bed temperature
thermocouple, the high-temperature camera device comprises a high-temperature camera and a video data output port, the high-temperature camera is embedded into a temperature detection end of the bed temperature
thermocouple, and a video data output port is connected into a
junction box of the bed temperature thermocouple; the high-temperature camera is used for collecting video data in a
hearth of the thermal power generation equipment; and the video data output port is used for sending the video data to the background
processing device, so that the background
processing device displays a video picture corresponding to the video data through the
display device. By applying the device, the
system and the method described by the invention, the efficient collection of the temperature in the furnace can be realized, and the technical personnel can accurately and efficiently judge the
combustion condition in the furnace.
