Problems solved by technology

However, ordinary optical life detectors need to be judged by search and rescue personnel based on the image. Due to the serious loss of the image in long-distance transmission and the low resolution, it is easy to cause misjudgment
In addition, it is impossible to judge the vital signs of the trapped person in a coma

Embodiment Construction

[0047] see figure 1 , in this embodiment, the intelligent image-type vital signs detector includes a main control terminal 1 with a main power supply and a display, a retractable probe rod 3 containing a signal transmission line 2, a camera probe 4 arranged at the front end of the probe rod, and a front light source 5 And the front-end signal processing unit.

[0048] The camera probe adopts a dual-mode camera with an infrared camera and a color camera. The CCD image sensor inside the camera probe receives the reflected light signal on the surface of the object, converts the reflected light signal into an electrical signal, and performs signal processing by the front-end signal processing unit; The front-end light source is used to provide illumination for the color camera; the infrared camera can directly collect video signals under light conditions or low-light conditions; using the infrared camera to detect under low-light conditions can greatly reduce power consumption and...

Abstract

The invention discloses an intelligent image-type vital sign detector, which comprises a main control terminal with a main power supply and a display, a retractable probe rod containing a signal transmission line, a camera probe arranged at the front end of the probe rod, a front-end light source and a front-end signal processing Unit; the camera probe adopts a dual-mode camera with an infrared camera and a color camera, and the CCD image sensor inside the camera probe receives the reflected light signal on the surface of the object, and converts the reflected light signal into an image signal, and the signal is processed by the front-end signal processing unit Processing, to obtain the victim's vital sign parameters such as heart rate and breathing rate; the image signal is also transmitted back to the main control end by the cable in the probe rod; the front-end light source is used to provide illumination for the color camera. The invention can effectively improve the reliability and accuracy of traditional optical vital sign detection.

Description

technical field [0001] The invention relates to an optical vital sign detector, in particular, it can be used for rescue and relief work in disaster places such as earthquakes and mine disasters. It is used to detect the human body in narrow holes or ruins and detect its vital sign parameters, and actively prompts the rescuers. Background technique [0002] Life detector is a high-tech rescue equipment used to detect signs of human life in disaster scenarios. After years of development, the current domestic common life detectors include infrared life detectors, audio life detectors, radar life detectors and optical life detectors. The infrared life detector uses the infrared radiation difference between the human body and the surrounding environment to separate the human target to be searched from the background by imaging. This type of life detector is suitable for rescue work in fire, smoke and dark environment. The audio life detector uses advanced sound vibration sens...
