Anti-theft alarm system technology intelligent trend

Anti-theft alarm system technology intelligent trend According to the actual site environment and the user's security requirements, a reasonable choice and installation of various alarm detectors can better achieve the purpose of security. When choosing and installing an alarm detector is not appropriate, there may be loopholes in security precautions, failing to meet the strictness of security precautions and creating an opportunity for intruders, thereby bringing undue losses to the security protection work.

Alarm detectors require tamper-proof and vandal-proof functions. When the alarm detector is damaged, people short-circuit or open circuit their transmission lines, and they illegally attempt to open their protective covers, they should all be able to generate alarm signals; in addition, the alarm detectors should also have certain anti-jamming measures to prevent all kinds of errors. The phenomenon of newspapers, such as: prevention of pets and pet harassment, resistance to false positives due to changes in environmental conditions, etc.

The sensitivity and reliability of the alarm detectors influence each other. Reasonably selecting the detection sensitivity of the alarm detector and adopting different measures against external interference can improve the performance of the alarm detector. The use of different anti-jamming measures determines the performance of the alarm detector in different environments. Understand the performance and characteristics of various alarm detectors. According to different use environments, rational allocation of different alarm detectors is the key link of an anti-theft alarm system.

Digitization, wirelessization, and integration are the technological development trends of anti-theft alarm systems. In order to meet the requirements of China's accession to the WTO/TBT (Technical Trade Barrier Agreement), the current anti-theft alarm products must pass 3C certification. With the new products introduced by many manufacturers this year, it is not difficult to find the technical development trend of anti-theft alarm products:

1, more stable / reliable: If the detector needs to be resistant to RFI / EMI, lightning protection, etc., to adapt to harsh climate;

2, more kinds of functions: such as the detector adjustable frequency, anti-blocking, anti-spray cover, anti-damage, etc.;

3, more exquisite, compact appearance: in order to meet the increasing taste of interior decoration needs;

4, more intelligent design: easy to set / disarm, user-friendly operation interface;

5, more powerful networking features;

6, more convenient expansion.

The above trends are in fact based on the three core technologies of digitalization, wirelessization, and integration.

In general, the trend of anti-theft alarm products, product technology will be digital, wireless, integrated under the premise of seeking to break through. In the application market, we will move in a more detailed direction - for different markets, introduce different products. Taking the application of the fastest-growing residential community as an example, some manufacturers stated that the directional curtain + anti-pet detector designed for residential communities has low cost, simple installation, wireless network alarm system suitable for home use, and intelligent community Security + alarm integration system products will be the highlights. In addition to the indoor/outdoor applications of residential quarters and commercial buildings, outdoor applications such as airports, docks, farms, mines, and oil fields are still waiting for manufacturers to expand.

Medical Type Freeze Dryer


GZLY series freeze dryers use double color touch screen and PLC as control center, control system stable and reliable. It can store 33 groups of freeze drying program, and each program can be set up 36 segments. It can display freeze drying curve and automatically records data.

Main Features:

1. The equipment design, selection, and installation meet production requirements. It is easy to clean, disinfect or sterilize, facilitate production operations,  and maintenance, and can also avoid errors and reduce pollution.
2. The surface of equipment directly in contact with drug is easy to clean, smooth, easy to clean or sterilize, and resistant to corrosion, and chemical changes or adsorption of drugs will not occur. Lubricants, coolants, etc. used in the equipment can not cause contamination of the medicines or containers. 
3. The main fixed pipeline connected to the equipment shall indicate the name and direction of the material.
4. The preparation, storage and distribution of purified water and water for injection should prevent the growth and contamination of microorganisms. The materials used for storage tanks and pipelines should be non-toxic and corrosion-resistant. The design and installation of the pipeline should avoid dead ends and blind pipes. Storage tanks and pipelines are required to provide cleaning and sterilization cycles. The vent of injection water tank should be equipped with a hydrophobic sterilizing filter that does not come off the fibers. The water for injection can be stored at a temperature above 80°C, at a temperature above 65°C, or below 4°C.
5. Instruments, meters, gauges, scales, etc. used for production and inspection, whose scope of application and precision shall meet the inspection requirements of production, have obvious conformity marks, and be regularly calibrated. 
6. Production equipment should have obvious status signs and be regularly repaired, maintained and verified. Equipment installation,  and maintenance can not affect the quality of the product. Unqualified equipment should be moved out of the production area if possible, and should be clearly marked before being carried out. 

7. The equipment of production and inspection should have records of use and maintenance, and be managed by special personnel.
