It is used by government departments such as military, customs, maritime patrol, firefighting, security, rescue, and aerospace. This product was developed by the United States high-tech companies combined with the world's most advanced biochemical, dielectric, ultra-low frequency transmission and DNA technology. Apply for a number of technical patents, this model is currently the most mature design of DKL company.

LifeGuardTM Life Detector provides rescue personnel to enter into the search and rescue site to confirm whether there is anyone inside the rescue site, reduce the degree of danger when the rescue personnel search and rescue, and detect any survivors behind the shelter at the first time. Passive reception is used to detect the direction of the remote weak heartbeat dielectric field, and only detects living humans without interference from other animals. It can pass through various obstacles such as steel plates, cement, composite materials, and trees to make detection. The distance is up to 500 meters in the open space and 1 km above the water. With special treatment, it is suitable for all kinds of bad weather conditions, it is easy to maintain and has a very low failure rate. For example, it can generate detected image and sound information when combined with portable computers and dedicated artificial intelligence software, further improving the discriminative ability of operators. At the same time, it can also reduce the time for novice training. LifeGuardTM Life Detector Applications: Haiphong: Sea, Coast, Mountains, Ports, Empty Houses, Cabins, Containers, and other illegal stowaways may hide. Rescue: Rivers, lakes, mountains, Earthquake landslides, mine explosions, fire scenes, surviving target searches, and confirmation of survivors can also be used to track the lives of search and rescue personnel. Search and tracking of police/security/military danger zones and complex obstacle areas can be detected early. Objectives, to reduce casualties. Used in conjunction with other life search instruments, such as search dogs, sound/image detectors, infrared/thermal imaging detectors, etc., to significantly improve the overall search and rescue effect.

US DKL life detector operation

First, the operation method

(a). Preparations (please refer to Figure 4) 13. Take the DKL out 14. Set the selector to any position from 1 to 6 (beginner to 1) 15. Pull the antenna to the longest position 16. If necessary, start the laser. 17. Hold the DKL and let the arm hang down for a “clear” action. 18. With the arm bent and lifted upwards, place the DKL in front of the chest and complete the preparatory position. The DKL is held horizontally down 1 to 2 degrees to minimize the effect of gravity on the detection rod. 19. Repeat 5 and 6 until you are skilled.

(II). To start the operation 1. During your practice, ask your companion to stand three meters ahead of you. 2. From “Clear” position to “Ready” position 3. If you are right-handed, move DKL from right to left If there is a human body electric field detected, the detection rod will shift to the right; then move DKL from left to right, if there is a human body electric field detected, the detection rod will shift to the left. After the user senses the electric fields on the left and right sides and places the sensor bar at the center of the two electric fields, the sensor bar will automatically point to the strongest part of the two electric fields and “lock” the target “automatically”. 4. Ask your partner to move to the right or left. If the detection is successful, the sensor will move along with the target while it is locking the target. 5. Repeat steps 2 to 4 until you become skilled. 6. When moving DKL is detected, please note that the action must be in a straight line (please refer to Figure 5). It cannot be formed into an arc, otherwise it will result in detection failure or error. 7. The speed of movement is too slow, and the polarization phenomenon may also fail because it cannot generate enough torque to push the detection rod; if it moves too fast, it will cause the detection rod to oscillate due to the user's swing and it will also lead to failure detection. Measurement. 8. To detect again, reply to the "Clear" position, and repeat steps 2 to 4 and so on. The "clear" will eliminate the original "polarization" and can be repolarized by another 2 to 4 actions.

(III) Detection of Success or Failure 1. When you are from right to left, from left to right, and then placed in the middle of two electric fields, one detection can be completed. 2. When practicing, if someone is in front of you and the detection fails, start from the “clear” position and practice again. 3. If the detection is successful, "lock the target". When the target moves, the detection bar also moves. If you use a laser at the same time, the laser will follow the target. 4. Ask your companion to hide behind the wall and try to find out his location, but be aware that there may be a deviation of one metre or more due to the “refracting effect” of the wall. Sometimes the target sticks into the wall, and the human body will leave a residual electric field on the wall. Even if the target has left the site, the DKL may still detect the residual electric field and make mistakes. 5. When you detect the target and the lock is complete, but there is a car passing, the detection rod moves with the car.

(d). How to determine the target position (Refer to Figure 6) The operator detects in two different directions and locks the target. The point that crosses these two directions is the correct position of the goal.

(e) How to find the goals in the buildings (Refer to Figure 7)

1. First lock your partner with DKL and make sure that the detection bar moves with him as your partner moves.

2. Ask your companion to walk around the building.

3. If there is a living person in the building, when your partner walks in line with the three persons, the operator and the living person, because the living position is closer to your (operator) than your partner, the electric field Stronger, so the sensor will turn to lock the living people hidden in the building and not move with your peers.

4. If there is no living person in the building, your companion will walk around the building and the detection bar will lock your partner and follow him around.

5. If it is determined that there are living people in the building, use (4) above to cross-check and determine the correct position in both directions.

Second, training in the use of personal computer software can assist in training. When the operator operates the DKL, a sharp sound (TONE) appears and the detected signal (larger amplitude) appears on the computer screen. Sixth, maintenance and maintenance on weekdays just wipe with a dry cloth or slightly damp cloth. The detection rod part of the screw can be properly sprayed WD-40 lubrication. If there is any malfunction of DKL, please do not repair it or even dismantle it yourself, notify the supplier immediately.

Third, to know all parts

1. Telescopic antenna 2. Antenna bottom 3. Laser switch 4. Detector rod assembly 5. Body 6. Retain function button 7. Select button 8. Computer switch 9. Computer light 10. Battery charging port 11. Laser 12 Trigger button

Fourth, the principle of action

When the DKL heart beat detector sweeps over the human body electric field, it will produce instantaneous polarization phenomenon, that is, generate positive and negative poles, and then generate torque, push the detection rod, so that the operator feels "detection" results. This detection is done without any AC or DC power supply, but by the polarization generated torque. The DKL is equipped with a special electromagnetic filter that filters out frequencies that are different from humans in animals other than humans, such as dogs, cats, cows, horses, pigs, etc., so that the DKL heartbeat detector only senses the human frequency. The electric field. DKL operation does not require any AC and DC power. Its equipped DC rechargeable battery is still for laser operation. When the battery is dead or fails, laser light cannot fire, but DKL can still operate normally.

V. Work scope

(A). The effective distance DKL is equipped with two different detection rods. The long-distance detection rod can reach a distance of 500 meters and the distance from the detection rod 20 meters. When DKL encounters obstacles such as reinforced concrete walls, steel plates, etc., the detection distance decreases.

(b). Vertical angle 1. Without obstacles: 60 degrees up and down, totaling 120 degrees. 2. When there are obstacles: 40 to 50 degrees up and down, totaling 80 to 120 degrees. (C). Horizontal angle (please refer to Figure 3) Left and right two degrees, totaling 4 degrees. This article is provided by China Rescue Equipment Network.
