Metal detector market analysis

Issue Time:2020-10-27

With the increasingly fierce competition in the handheld metal detectors machine market, quickly and effectively grasping the market development has become the key to the success of enterprises and decision makers. Market analysis is a scientific and systematic work that directly affects the planning of enterprise development strategies, the design of product marketing plans, the formulation of company investment policies, and the determination of future development directions. Market analysis does not simply evaluate the market from a certain level. To obtain practical and guiding conclusions, it is necessary to conduct a comprehensive and detailed analysis of the market from a professional perspective. Only in this way can we maintain a clear development mindset at all times, not get lost due to the complicated information, and remain invincible in the increasingly fierce market competition. In response to this need of enterprises, we conducted research on the handheld metal detector market and wrote this analysis report to help enterprises make decisions.

 

   Chapter One Handheld metal detectors machine product overview

  Hand-held metal detectors machine are designed to detect metal objects carried by people or objects. It can detect weapons, explosives or small pieces of metal in packages, luggage, letters, fabrics, etc. carried by people. The special appearance of its sensitive surface makes it easy to operate. Better than ring sensor type hand probe. Ultra high sensitivity, special application. Such as prisons, chip factories, archaeological research hospitals, etc. Hand-held metal detectors (PD140V palm-type hand-held metal detectors, imported metal detectors for body search) are used to check the specific location of the metal carried by the person. It can also be used with metal detection doors. When the "security door" alarms and finds metal objects When using hand-held metal detectors machine, you can find the exact location of hidden metal objects. The metal detectors machine adopts a rectangular detection head with a detection area of ​​12 cm. When inspecting the human body, the inspection work is completed at one time from top to bottom.

  Before use, first open the battery box cover on the back of the instrument and insert the battery. This instrument uses a 9V laminated battery. Please note that the nominal voltage on the battery must be 9V. Other voltages must not be substituted. The power consumption of this instrument is very low. Each new battery can work for about 50 hours. When the battery energy drops to 10%, the instrument can no longer work normally. At this time, the horn will make an intermittent clicking sound, prompting us to replace the battery.

  During use, the security inspector holds the handle with his hand, presses the start button with his thumb, and then releases it. The signal light of the instrument starts to flash, and the horn emits a very slight buzzing sound at the same time, indicating that the instrument is in working condition. The staff held the turned-on instrument and scanned the surface of the person (or object) to be inspected. If there is a metal object, the instrument will make a sound. After the inspection is completed, the stop button should be pressed to avoid wasting battery power.

  How to distinguish the size of metal objects

Physiological studies have shown that human hearing is relatively slow to changes in volume (logarithmic relationship), but is more sensitive to changes in pitch (linear relationship). According to the above conditions, the instrument uses the pitch to determine the level of metal objects. Size, which is different from other similar products, it allows us to more accurately distinguish metal objects of different sizes.

When the probe of the instrument sweeps the human body (object), if a low sound is emitted, and the sound will gradually disappear after the probe stays above the sounding place, we can determine that it is a very small piece of metal, such as a belt buckle, Zipper etc. If the sound is very sharp, even if the probe stops moving, the sound is still continuous, it must be a large piece of metal, such as a dagger, a pistol, etc.

   Chapter 2 Hand-held metal detectors machine production technology

  Diversified new detection technology

  Multi-beam technology

  In many detection technologies, infrared detection is the most common detection technology; and in active infrared detectors, the development of single beam technology has been difficult to meet people's requirements for detectors. According to relevant sources, the active infrared detector technology mainly uses one transmission and one collection, which is a linear prevention. It has been developed from the initial single beam to multiple beams, which can effectively reduce false alarms and strengthen the reliability of prevention. In order to expand the protection range and overcome the shortcomings of the insufficient protection range of ordinary active infrared beams, many manufacturers have developed multi-beam grating active infrared beams, which are actually an extension of single-beam active infrared technology.

   It is understood that the infrared beam of the detector is fired and retracted to build a safety protection area. Once an object blocks the infrared beam, the detector will respond to the interruption of the infrared signal and alarm, which plays a role in preventing theft. The single-beam infrared beam has only one set of pairs of rays, which makes the coverage of the detector only a small area, thus giving criminals such as thieves an opportunity to take advantage of it. Therefore, it has multiple sets of beams that can be crossed from different directions and angles. The multi-beam technology of shooting was born. This technology increases the coverage of the beam and becomes more complex, greatly enhances the safety of prevention, and effectively reduces the occurrence of false alarms and false alarms.

   anti-masking, spraying and pet detection technology

When the detector is working, it is often interfered by some deliberate vandalism or the inadvertent entry of other objects, resulting in false alarms or false negatives. For this, various detection measures to avoid are constantly being studied. Come out, then the most important technologies are anti-masking, anti-spraying and anti-pet technology.

  According to relevant sources, since motion detectors are usually based on passive infrared (PIR) technology that detects the heat radiated by intruders, they can easily be fooled by simply covering the detector. The anti-blocking system triggers an alarm when the detector lens is covered or blocked. Today's anti-blocking detectors are more advanced. Even spraying transparent hair spray on the lens will trigger the alarm. Therefore, a technology called "multi-point anti-masking and integrated spray detection" can fully guarantee the detection reliability of the detector. It includes behind-the-lens metering function, infrared receiver reflection function and integrated spray detection functions. The behind-the-lens metering function prevents substances from flowing through the front of the metal detectors machine; the infrared receiver reflection function prevents objects from approaching or blocking the detector. If detectors with anti-masking technology are installed in vaults, safes and other places, the robbers will not easily succeed.

   Cats, dogs, birds and other animals (even children) unconsciously enter the detection area and cause false alarms often occur. In order to avoid this, anti-pet intrusion detection technology

    The difference between dynamic checkweigher and static checkweigher
    Checkweigher is a kind of automatic checkweighing equipment widely used in the production line of pharmaceutical, food, chemical and other industries. It can detect overweight and underweight unqualified products in the production line in real time online. The weighing methods of weighing equipment are divided into dynamic and static weighing methods. What is the difference between them, let's understand together below:
