Ballistic Silence of Special Years

The detonating device inside the cardboard box looks very complicated, with crisscross lines and multi-layer installation. This is the first time Tong Zhi has seen this structure.

To dismantle an explosive device, it is necessary to find out what type of explosive device it is.

The general type of trick explosive device is not difficult for anti-explosive personnel who have received professional training and have certain experience in detonating explosives.

Therefore, in order to achieve their goal and prevent the device from being dismantled by anti-explosive personnel, criminals will try various methods to make the detonation technology more complex and changeable, making it difficult or even impossible to remove the device.

Detonation technology includes several major categories of instantaneous detonation, delayed detonation, remote detonation, and reaction energy detonation, and these major categories are divided into multiple sub-categories.

For example, the most common type of instantaneous detonation is landmines, which are relatively simple, such as pressing, pulling, and loosening.

Delay detonation inside is divided into physical delay, chemical delay, electronic delay several.

There are two types of remote control detonation, wireless remote control and wired remote control.

Among all the categories, the last one is the one most loved by criminals and KB elements - reactionary explosives.

After years of development, the reactionary energy detonation technology has been very diversified. Some avoid tilting, some avoid shearing, some avoid decompression, and some have multiple designs of composite devices, which is hard to guard against.

Tong Zhi suddenly thought that Zhuang Yan was demonstrating to himself.

He designed the cover of the explosive device very simply, without any trick links, so that he can easily open the cover, which means to tell himself that even if you can see the inside, you can't remove it!

indeed.

The structure solemnly set up is very complicated, and he really admires it. This senior colonel has real skills.

In fact, he didn't know that one of the important courses that Zhuang Yan had studied in foreign special forces colleges was underwater blasting and demolition.

For solemnity, play blast?He's definitely a master at it.

However, this also aroused Tong Zhi's competitive spirit.

I am not a fool, and when it comes to dismantling bombs, I have also dismantled real ones.

He carefully used insulating pliers to separate the vertical and horizontal lines one by one, so that they would not block his view, so that he could see the circuit board below more clearly—he could almost conclude that the explosive device was an electronic detonating device main body structure.

As for whether there are other compound detonation methods, it can only be known after careful inspection.

There were a lot of beads of sweat on Tong Zhi's forehead.

It's not because I'm afraid that I'll miss it. Even if the detonator explodes, it won't kill anyone, and it can't even hurt anyone. At most, it's the power of a small firecracker.

But the pressure is that he doesn't know how long his explosive device can block the solemnity, so he set up a bomb with a triple compound device for him.

That thing includes three things: balance device, anti-cutting device and mechanical detonation.

The reason why remote detonation is not used is because in fact, although remote detonation sounds the most high-end, it is actually the lowest-end detonation method today.

Because it is too simple to deal with it, just put a high-power jammer to the side to cut off all signals, and the wireless remote control will immediately catch it blind.

Beads of sweat began to fall to the ground, and Tong Zhi knew that he had encountered a hard stubble, but it was hard to get off, so he had to bite the bullet.

Even if you lose time, you can't miss it.

Soon, the wiring was opened, revealing the second layer of structure inside.

"really……"

He couldn't help showing a smile.

As I thought, the multi-layer structure must be a composite explosive device.

He saw a balancing device hidden under the wiring.

This is a classic anti-tilt detonator with two power circuits, A and B.

The A circuit is in the light, and the B circuit is in the dark, hidden in such a position that people cannot find it.

Make a V-shaped groove close to a straight line in the A line, bury a copper wire, and finally cut the copper wire at the V groove position, and place a small steel ball to touch the two ends of the copper wire to maintain power.

When the steel column is always in the V groove, the current is unblocked, and the detonating device is in stable loading, and when the small steel ball is shaken and deviated from the V groove, the moment A circuit is powered off, the B circuit will be automatically activated, and the B circuit will be energized at the moment will detonate immediately.

This kind of device will make the bomber's life worse than death when dismantling the bomb, which means that you must find the B circuit and cut off the detonation power, but the B circuit is generally not in the open, you have to find it, and even scratch off the circuit board But when you look for circuit B, if there is a little vibration, the steel ball will deviate, and the rest is BOOM!

Another kind of anti-tilt device uses a very common glass tube-obviously, this thing can be found everywhere, fuses and the like are this kind of tube, cut one end and remove the tungsten wire inside, put it in a hardware store. The small steel balls that can be bought are sealed at both ends to make a trigger circuit. As long as the small steel ball loses balance and rolls to any direction, it will detonate when it touches one pole.

Of course, he didn't believe that Zhuang Yan would only install this anti-detonation device.

"There should be..."

He looked carefully at the side of the cardboard box, and after making sure that there were no anti-disassembly makeup such as copper wire on the side panel, he cut the side panel open again.

Now, the projectile body of the whole detonating device has been completely exposed.

He looks sideways.

Sure enough, there was a third layer.

There was a small gap in the middle of the third floor. Since the wiring and conditions inside could not be clearly seen from the side, Tong Zhi had to use something like a medical speculum to put a small mirror in to see.

Finally, it took him 2 minutes to take a closer look at the third floor.

That's an anti-clipping circuit.

The anti-shear kinetic energy detonation technology is usually used in electronic timed explosive devices, which is the kind commonly seen in movies. When eliminating this electronic timed detonation device, the method of cutting off the power supply is often used to stop the detonation. Therefore, Whether it is a criminal or a bomber, set a wire connected to the firing pin on the line, or set up a circuit that can generate an electric pulse or connect to a relay. When the wire is cut off, the firing pin is released to cause detonation. ; Or it is the direct detonation of the connected circuit, or the electric pulse generated to trigger the explosion or the explosion through the relay.

Now, it seems like the hit method is on.

"You're just giving me a problem..."

Tong Zhi took a deep breath.

"You think I can't take it apart?!"

Feeling competitive, Tong Zhi stretched his hands and feet. Now he wants to remove the stabilizer on the first floor. What is the best way to remove it?
There are two ways - either to find the B circuit and destroy it, or to stabilize the circuit of the A circuit and make the small steel ball on the V groove invalid.

To make the small steel ball ineffective, it is necessary to connect the copper wires at both ends to keep them energized.

He removed a small copper wire and two small sharp-nosed clips from the bomb disposal kit, wound them separately, and then inserted the clips into the copper wires at both ends to clamp them tightly.

In this way, even if the small steel ball is removed, it can still be powered on, and the hidden danger can be eliminated by strengthening it later.

This process may seem simple, but it is actually a matter of extremely testing the psychological quality.

As long as the hand shakes, just shake it lightly, and the bomb disposal will fail.

In reality, when encountering a real bomb, a miss is basically equivalent to glory.

Soon, the clip went up.

Tong Zhi let out a sigh of relief.

Now, he wants to take that little steel ball away, as long as the device doesn't explode after taking it away, it means that he has passed the first level!

He stretched out his needle-nose pliers and gently pinched the small steel ball. His professionally trained hands were extremely steady.

Solemnly engaged in this device, in fact, to test his own psychological quality.

This is a test mode for him.

"Be obedient...be obedient..."

Tong Zhi muttered, as if coaxing a naughty child to calm down.

The pliers caught the small steel ball...

Now, as long as he lifts it lightly, everything will have results.
