LRAD-L1000

http://www.lrad.cn/lrad-l1000/
Compared with the traditional amplifying system, the LRAD-L1000 is a revolutionary new technology. It has a very long-range shooting ability, which can clearly transmit the sound information to hundreds of meters away, even it can pass through some buildings; it has a powerful deterrent power, which can force the audience to leave the forbidden area automatically; it has a precise orientation ability, which can aim at a certain angle to launch an unbearable stimulating sound wave, but it is not uncomfortable in other angles.

LRAD-L1000 Long Range Acoustic Device 

LRAD-L1000 Characteristic

LRAD-L1000 Long Range Acoustic Device is evolved from an ultra-high-powered loudspeaker. It is a non-lethal weapon of new concept by directional emission of super-sound waves to dispel the rioters. As a security device, it has the characteristics of light, firm and easy to operate, and has a good cost performance for law enforcement agencies such as public security. Therefore, it is also a high-tech police equipment. In actual use, the operator can ask the target group to cooperate with the action first in a way of shouting,and if the target does not respond properly, the device can be aimed at the target within 15-30 degrees, and a 151 dB warning tone is applied to force the force. Thus forcing the target to cooperate.
It does not output the sound in the form of a sector like a normal speaker, which eventually the intensity of the sound decreases rapidly with distance. Rather,like a spotlight, it can concentrate the sound in one direction and spread it in a long distance,and can maintain enough intensity within the effective distance to achieve the functions of long-distance shouting, warning and deterrence. Lrad-l1000 can even transmit extraordinary sounds pass through some buildings with extraordinary clarity, which has the characteristics of high orientation, high sound intensity and high definition.
It can transmits important information,commands,warnings to 2000m (open environment) clearly due to its high directionality and powerful sound output. It can also output a warning tone with a strong deterrent (1m 151dB) to force the target to cooperate.
LRAD-L1000 can record and play the command content you need through its MP3 player and microphone.No matter it is used for search, rescue, patrol, or for special police operations (including crowd dredge, traffic and access control, blockade, card setting, criminal detention, etc.), this mobile device can be used to enhance public security.At the same time,it can ensure that nearby people and bystanders will not hear too strong sounds. The LRAD-1000 is the first choice for “long-distance, high-definition sound output, low power consumption, high definition, safe and convenient operation”

LRAD-L1000 Acoustic radiation pattern

L= Low gear mode 
M=High gear mode 
Red area:
L- It is forbidden to enter the 15m area when the equipment is working.
M- It is forbidden to enter the 75m area when the equipment is working.
Yellow area:
L- It is forbidden to enter the 15m area without hearing
protector when the equipment is working.
M- It is forbidden to enter the 75m area without hearing
protector when the equipment is working.
Green area: 
L- It is safe area when the equipment is working.
M-It is safe area with hearing protector when the equipment is working.
Attention:
Hearing protection should reduce noise by at least 20 dB.
Disposable foam earplugs can be used as a hearing protector

Ad Hoc Networks Used in Oil and Gas Field Wireless & SCADA Application

Image
The oilfield is located in remote and offshore areas, and production management is more difficult. Usually it is necessary to reduce the difficulty of on-site management by means of huge gathering pipelines and increased oil production platforms.The production parameters of oil well can not be obtained normally due to weather changes and transportation tools.Seriously affecting the automatic management of oil well. Using wireless IP sensor network technology, various well field sensors and instrumentation data such as load sensors, angular displacement sensors (or pulse generators), monitors, electrical parameters sensors, etc., can be collected into remote RTU, and then transmitted to the production center through other communication methods. Our  solution: Advantage: Reduce maintenance by ensuring high reliability Network coverage in difficult terrain and wide space area Withstand harsh weather conditions Reduce the cost of large-area deployment by eliminating cabling an...

Ad Hoc Networks Used in Field search and rescue system

Image
The field search and rescue system is mainly based on search and rescue management system, using radio frequency identification, sensors, wireless direction finding, geographic positioning,ad hoc networks, computers and other technical methods for information technology equipment for field treatment. The system is mainly used for combat individual soldiers, battalion rescue teams, armored vehicles, ambulances (armor), helicopters, and field rescue agencies to search and rescue the wounded. Our plan: Active RFID technology is used to realize the safe reading and writing of health information box by handset.According to the special application and requirement of field search and rescue system, it supports ad hoc net communication and GPS positioning of information box, supports the targeted search and rescue operation of information box, ensures the safety and reliability of wireless data communication, optimizes the design and implementation of anti-collision algorithm. Multiple inform...
