Abstract

The invention belongs to the technical field of fire fighting equipment, and in particular relates to a fireman rescue device with wireless direction-finding positioning function. The rescue device consists of a multi-radial wireless receiving circuit, a wireless transmission circuit, a single-chip microprocessor, a motion sensor, a temperature sensor, an orientation indicator, a distance indicator, a sound alarm device and a power source, wherein the multi-radial wireless receiving circuit consists of a magnetic antenna group, a receiving control circuit, a filtering-amplifying circuit and an intermediate frequency receiving circuit; the wireless transmission circuit consists of the magnetic antenna group, a transmission drive circuit and a transmitting-frequency modulation circuit; the motion sensor, the temperature sensor, the orientation indicator, the distance indicator and the sound alarm device are connected with I/O ports of the single-chip microprocessor; and the power source is connected with the components to supply power. Due to the wireless direction-finding positioning function, the rescue device reduces rescue blindness in harsh environment and greatly improves rescue efficiency, thereby saving the lives of firemen to the utmost extent.

Description

technical field [0001] The invention belongs to the technical field of firefighting equipment, and in particular relates to a search and rescue device for firefighters with wireless direction finding and positioning functions. Background technique [0002] As one of the routine personal protective equipment for firefighters, the firefighter's rescue device has played a huge role in protecting the personal safety of firefighters. When firefighters are fighting, they are equipped with it to enter the disaster scene. Once the firefighters have no movement response for a certain period of time, the rescue device will send out sound and light alarm information to guide rescuers to search and rescue firefighters in distress. However, due to the complex and changeable environment of the disaster scene, there are many noise sources. Coupled with the barriers of surrounding buildings, the transmission distance of alarm information is limited, and the search and rescue process is extr...
