Novel wrist type thermal imager for fire control

Abstract

The invention relates to a novel wrist type thermal imager for fire control. The novel wrist type thermal imager includes a front housing, a signal transceiver, an LCD display screen, a microphone, a loudspeaker, a rear housing and a human face recognition module. The front housing and the rear housing are assembled in a matched way into a sealed housing. An infrared detection lens is mounted on the inner side face of the rear housing. An infrared detector assembly is arranged behind the infrared detection lens. The human face recognition module is arranged above the infrared detector module. An electronic assembly is arranged below the infrared detector assembly. An automatic focusing ring is arranged in front of the electronic assembly. A visible camera lens is arranged in front of the automatic focusing ring. The invention has beneficial effects that inter-communication among fire controllers is facilitated by the combination of the signal transceiver, the microphone and the loudspeaker; automatic tracing of locations of trapped persons in a fire ground and automatic focusing of the infrared detection lens can be realized; the novel wrist type thermal imager is hand-free and time is saved substantially.

Description

technical field [0001] The invention relates to the design field of fire-fighting auxiliary equipment, in particular to a novel hand-worn thermal imager for fire-fighting. Background technique [0002] Thermal imaging is the science of using optoelectronic devices to detect and measure radiation and to correlate it with surface temperature. Radiation is the movement of heat that occurs when radiant energy moves without a direct conducting medium. Modern thermal imaging cameras work by using optoelectronic devices to detect and measure radiation and to correlate it with surface temperature. All objects above absolute zero emit infrared radiation. The infrared thermal imaging camera uses the infrared detector and the optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector to obtain an infrared thermal image, which is consistent with the thermal di...
