As an alarm information collection device, the importance of the detector in the anti-theft alarm system is self-evident. The stability of the detector directly relates to whether the entire anti-theft alarm system can operate normally. Among the nearly 20 manufacturers visited, various manufacturers have installed different types of detector products, ranging from probing technology to convenient design of appearance, which can be described as varied and varied. Among the many detection technologies, in addition to the traditional infrared, microwave, vibration, and ultrasonic detectors, the electronic fences, vibration cables, and vibration fibers of the perimeter protection class also appear. In addition, in order to meet the practical needs of users, many manufacturers have set their sights on the research of new detector product forms, which are mainly reflected in the special requirements under different application environments.
While creating a variety of product forms, detector technology is constantly improving. During many years of research and development, it has been the main theme of the anti-theft alarm industry to overcome false alarms, omissions, and interference. In this regard, R&D personnel selected multi-beam, multi-detector elements, and micro-processing digital processing technologies to improve their sensitivity and probing accuracy. At this year's show, we have seen manufacturers make more detailed adjustments to the internal structure of the detectors, such as Resike and Honeywell, in the microwave detector technology to the original X-band to K-band. The K-band microwave technology operates at a frequency of 24.125 GHz, which covers the detection area more evenly. In addition, the K-band also reduces the ability to penetrate the wall (“infiltrationâ€) so that false alarms are not caused by pedestrians around the protected area. .
At the show, unlike the previous probes, manufacturers such as Bosch strengthened the lower window function in the detector to expand the scope and space area of ​​the detection zone, enabling detection of no-blind or minimum blind zones. According to Wang Yu, Bosch product manager, the lower window function setting is an extension of the scope of the detector, the detector has a limited range of detection, first of all, the area directly under the detector is easily become blind, although the previous products are The lower window function has been involved, but the user still suspects that the lower window is too small, and by enhancing the lower window function, the larger lower window detection range can be expanded, thereby improving the detection efficiency and accuracy of the detector.
Today, when pets are promoted to family members, cats, dogs, birds and other animals (even children) enter the detection area and often cause false alarms. Therefore, excellent performance of pet-proof detectors has become the focus of the company's R&D. In fact, the anti-pet technology has long existed, but it has been unsatisfactory for a long time. In particular, keeping pets has become very popular. Therefore, in order to avoid pet false positives, the research and development of anti-pet detection technology has continued. For example, Mean employs self-developed MASK chip with “random dynamic time-division processing†technology, which randomly samples every infrared signal in the signal processing and converts this cycle of infrared signals into corresponding digital signals. Stored in RAM, and get the infrared radiation frequency of the object in one cycle; then compare the infrared radiation frequency data of the object in a period of RAM with the infrared frequency of the human body stored in the ROM, if the detected frequency range is 6-12Hz, it is determined that pet activity, give up the alarm, if the detected frequency range is 0-5Hz, then it is judged that someone has invaded to make an alarm.
In order to reduce the influence of temperature changes on the infrared detectors, Jing Long developed a dynamic temperature compensation, namely "automatic temperature compensation" technology. The dynamic temperature compensation adopts an advanced compensation algorithm, which can also gradually perform intelligent compensation when the room temperature is increased or close to the body temperature of the human body. This expands the temperature range in which the infrared detector maintains normal induction, so that the temperature in the wide-state environment Under the same conditions, better detection sensitivity and accuracy can be obtained, and the false alarm rate can be kept to a minimum. Guo Zhihua, alarm product development manager of Shenzhen Haoen Technology Co., Ltd., also stated that for infrared detectors, the ideal temperature compensation technology can effectively reduce the probability of false alarms caused by “non-normal temperature sensing†of the detectors, thus making false alarms. The rate is greatly reduced. Not only that, Horne's anti-white light technology based on embedded software has also largely avoided false alarms caused by lights, incandescent lamps, and outdoor sunlight.
In addition, many manufacturers have incorporated modern aesthetics and humanized installation designs into the appearance and installation of the detectors, so that they can be better matched to the environment and provide installation, both indoors and outdoors. Scientific and convenient. Here, we also have to mention Bosch's newly introduced infrared/microwave three-technology detectors, which use a unique dual-body ergonomic sliding design, the detector built-in bubble level meter, it is easy for the installer to horizontal and vertical positioning; Angled angled pull-out terminal block is especially convenient for cable connection; its self-locking device can prevent airflow and insects from being completely closed without screws.
It seems that a good detector must not only have its own three-intelligence, four-probe detection and processing technologies, but also the appearance of beauty and the rationality and scientificness of installation. This was demonstrated in the products of many manufacturers of Shenzhen Amway Fair this year, which is rare in previous years.
