Why Hand Held Security Metal Detectors Is the Better of the Other
Why Hand Held Security Metal Detectors Is the Better of the Other
Metal detectors are common today at sporting events, outdoor events and gatherings, airports, night clubs, prisons, schools, production and distribution facilities. Developed in the 1960s at the beginning of the modern logistics age, portable metal detectors are a mainstay of employee security in many modern distribution centers. They are also used for security at checkpoints at airports, schools and courthouses, prisons and military installations. Today, you can no longer detect anything that has been stolen from a warehouse or a distribution centre. What follows is an overview of current security screening technologies, how they work and what kind of health problems they can cause. Anyone who has flown on an aircraft in the past ten years knows the use of handsticks for individual screenings, walking metal detectors, full-body scanners and luggage X-ray machines. One of the easiest and most cost-effective scanning devices is the hand-held detection stick. Hand-held detectors allow security personnel to find hidden metal objects that pose a security threat. High-quality safety metal detectors offer various alarm indicators, including optical LEDs, selectable acoustic alarms and vibrations. High-quality safety metal detectors are self-calibrated and make regular sensitivity adjustments superfluous. They are lightweight and equipped with a standard 9V battery that allows up to 80 hours of continuous operation. Handheld metal detectors are affordable and are often used in various facilities and checkpoints to improve security. Airport security uses large walk-in metal detectors to speed up security checks. Hand-held metal detectors, like most of them, use a similar electromagnetic field technology (EMF) to determine if you have metal on your body that cannot be used in an X-ray image. Nightclub staff have to scan guests as they enter the premises, and outdoor music events and sports stadiums use metal detectors to increase security. There are two main reasons why safety bars are used: to protect security personnel when searching for a person, and to protect and avoid a pat on the back. The use of a portable metal detector to scan the body allows security personnel to find contraband without putting anything sharp in their pockets. Individual screens, such as hand-held scanners and wands, can come in handy when your throughput and volume requirements are low. Safety bars warn you of a target with acoustic sound, target recognition light, vibration or a combination of these three. You can select the device that offers the most appropriate target response for your environment. Most importantly, the target of a weapon gives the member of the security team extra time to address the situation. Since hand-held detectors emit no radiation like X-ray machines they use an electromagnetic field (EMF) to detect metals. Security personnel will be able to hear acoustic sounds through an external speaker connected to a headset that goes through metal objects. Due to the large noise level in the vicinity, the security team member does not have to look at the metal detector, but only feel the vibration. A series of hijackings in 1972 led the United States to introduce metal detector technology to monitor passengers using magnetometers designed to log flight operations and detect spikes in trees. In 1995, systems such as Metor 200 emerged that were able to indicate the approximate height of metal objects on the ground, which allowed security personnel to pinpoint the source of the signal. A common development with other applications of metal detectors is that alternating current pulse systems use special coils and electronics that can be moved to improve the discrimination of the system.

Design of Consumptive Optical Fiber High Temperature Measuring Instrument
Design of Consumptive Optical Fiber High Temperature Measuring Instrument
1 IntroductionHigh temperature measurement plays an important role in aerospace, materials, energy, chemical industry, metallurgy and other fields. At present, in high temperature measurement, according to whether the measuring probe is in contact with the measured object, the temperature measuring instruments are divided into contact and non-contact.With the emergence of optical fiber technology, it provides conditions for the realization of contact temperature measurement. The contact optical fiber temperature measurement adopts a long quartz optical fiber as the temperature measurement probe and transmission system to keep the instrument away from the site with bad environment. At the same time, the optical fiber optical path is not affected by the environmental atmosphere, which greatly improves the environmental adaptability of the temperature measurement system. However, because the probe adopts the general radiation receiving principle, it is still difficult to solve the problem of emissivity. In order to overcome this problem, the principle of ash body temperature measurement is proposed. The colorimetric method can greatly reduce the influence of emissivity on the temperature measurement results. Under the best conditions, the influence can be reduced to zero. The advantage of such temperature measurement is that the temperature measurement response speed is fast, and the response speed is about 10s [3].The consumable optical fiber high temperature measuring instrument developed in this paper overcomes the above shortcomings and is a new method to measure the temperature of molten metal. Its temperature measurement accuracy is the same as that of the consumption thermocouple, but the temperature measurement cost is greatly reduced, which has great economic benefits and can completely replace the consumption thermocouple.2 principle of colorimetric temperature measurementColorimetric temperature measurement is a method to determine the temperature of an object by measuring the ratio of the radiance of the object at two different wavelengths. Its characteristic is that it can eliminate the interference caused by atmospheric, smoke, dust, ambient temperature and other factors on the measurement path.3 selection of working wavelengthAs can be seen from equation (3), it is very important to correctly select the wavelength and wavelength. Generally, the spectral radiance of the measured object is related to wavelength and temperature, as shown in Figure 1. The ordinate in the figure represents the radiation brightness of the blackbody, the abscissa represents the wavelength, and the temperature of the curve is getting higher and higher from bottom to top.From the curve in the figure, we can see several characteristics of blackbody radiation: (1) the total radiance increases rapidly with the increase of temperature. The higher the temperature, the greater the spectral radiance; (2) When the temperature is constant, the spectral radiance changes according to a certain law with different wavelengths, and the curve has a maximum value. The wavelength here is defined as that when the wavelength is less than, the radiance increases with the increase of the wavelength, and when the wavelength is less than, the change law is opposite; (3) When the temperature increases, the peak wavelength of spectral radiance moves to the short wave direction, the radiance of the object increases, and the luminous color also changes.The wavelength range is preliminarily set at 800 1000 nm, and there is no main absorption band of water vapor in this range, which can reduce the measurement error. When it is 800nm and 1000nm respectively, the relative sensitivity curve is shown in Fig. 2. The relative sensitivity of curve 1 in the figure is high. Therefore, it can be seen that it should be near 800nm. According to the relationship between the spectral response of the photodetector and temperature, it is required to have a good linear relationship. According to the linear relationship, it is better to take it near 950nm.After the experiment, the final choice = 890nm, = 940nm, the colorimetric temperature measurement effect is better.Fig. 2 relation curve between relative sensitivity and temperature
Application of Cable Fault Locator
Application of Cable Fault Locator
The application of cable fault locator in power industry and some industries using cables, especially in some complex power systems, it is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.
