Applicable fields of audio life detectors

　　What are the applicable fields of the audio life detector?

　　1. Applicable to the ruins structure of earthquakes, collapses, and building collapses, applicable to fire fighting, municipal administration, and mining structures, etc.

　　2. Applicable to rescue operations in confined spaces and where conventional methods make it difficult for rescuers to access (e.g., victims trapped in collapsed buildings, deep wells, mines, etc.). Accidents involving deformed cars, airplanes, ships, and trains, as well as places invisible to the naked eye, sewers, mines, and underground locations to search for missing persons.

　　 Audio Life Detector It has amplitude automatic memory and display functions, easy product operation, and noise shielding function. LCD automatic LCD display with luminous function.

　　The audio life detector uses the principle of sound waves and vibration waves, using advanced microelectronic processors and sound/vibration sensors for all-round vibration information acquisition. It can detect various sound waves carried by air and vibrations carried by other media. It filters non-target noise waves and other life detector background interference waves to quickly determine the location of trapped personnel. The high-sensitivity audio life detector adopts two-stage amplification technology, and the receiver frequency range of the frequency amplifier built in the detector is 1~4000Hz. After receiving the target signal, the host amplifies it again. In this way, trapped people can judge the existence of life by shouting, climbing, knocking, etc., to detect weak audio sound waves and vibration waves underground.

　　The audio life detector is a human-computer interaction-based detection system, including signal detection, reception, selection, storage, and processing. Key technologies in the development process include the development of: high-sensitivity sensors. Through the study of the mathematical model of sound waves and vibration waves, the determination of signal validity and the determination of the location of the effective signal source are determined. The audio life detector is an instrument that passively receives audio signals and vibration signals, so when rescuing, it is necessary to find gaps in the ruins to enter the probe, which is easily affected by on-site noise and the detection speed is slow.

　　 Audio Life Detector What are its main features?

　　Personnel detection and precise positioning

　　Appointment location, precise positioning function

　　Automatic background lighting control

　　Microprocessor control

　　Minimum noise display

　　Automatic storage function

　　Can simultaneously remember and display the audio values and simulations of 4 measurement points

　　High-performance filter: set bandwidth. Powerful sensitivity expansion function suitable for various on-site structural rings

　　Audio peak detection

　　Suitable for deep detection in narrow spaces, solving the problem of insufficient audio sensors, and can also detect very small sounds.

　　Omnidirectional audio sensor

　　The audio sensor can accurately locate the location of the victims.

　　 Audio Life Detector There are 6 different audio filtering options. The operator sets and compares the minimum and average values of the sound, stores and displays the measured data to facilitate the identification of the maximum location of the victims and accurately locates them.

　　How is the power supply?

　　Automatic sleep mode: If the device is not used within one minute, the device will automatically shut down. Under normal circumstances, the battery of the instrument does not need to be continuously charged for 10 weeks. Staff can understand the battery power status through the LED display.

　　What is the standard configuration of the audio life detector?

　　Host, omnidirectional audio sensor, audio probe (optional), headphones, audio sensor tripod, Chinese and English manuals, instrument box.
