Industrial design is not a new term for the security industry. Among the products that have been tested in the past, we have seen many security companies designing a product with the same intention as treating children. At the same time, we have also seen that the industrial design concepts of some products are still far from enough. With the convergence of security products in terms of parameters and performance, can companies polish industrial design weapons in the fierce competition? Industrial design is more than just surface kung fu. It also includes product structure and circuit design. They all affect the practicality, stability, convenience and durability of products. These performances have become an important consideration when users purchase products. .
The development of security products to today, the importance of industrial design is indisputable. It includes all aspects of product structure, appearance, circuit design and other aspects of the industrial production process in addition to the core manufacturing technology. The well-rounded industrial design can not only enhance the company's manufacturing and manufacturing efficiency, but also improve the product's many quality features, and it can enhance the company's differentiated competitiveness. Mr. Chen Liqiang, Product Technology Manager of Product Technology Department of Fermax (Shanghai) Electronics Co., Ltd. believes that industrial design is mainly based on the study of the physical characteristics of products and the interrelationships of various parts of the manufacturing system. It is standardized and simplified in this process. In addition to being beneficial to production use, the manufacturing cost of the product can also be reduced. Usually, the process design stage determines the manufacturing cost of a product by 80%. As a result, many of the product's quality characteristics have been fixed during the design phase.
With the expansion of the scale of application of security products and their increasing civilian use, as well as the maturity and improvement of their functions, users have gradually shifted their attention from the core technology of security products to the industrial design of products, such as circuit design, structure and design of products. These have become important factors for users to judge a security product to meet their actual application and aesthetic requirements, and manufacturers can increase the added value of the product by differentiating the product design.
Circuit design should not be isolated. It is worth noting that usually we directly equate industrial design with appearance. A complete design needs to consider each link, and each link is also influenced and coordinated with each other. For example, in the industrial design of security products, the circuit design is related to the structure, aesthetics, stability, cost, heat dissipation, etc. At the beginning, the electromagnetic interference resistance and system stability that are closely related to EMC (ElectroMagnetic Compatibility) should be taken into consideration, and the constraints on the appearance and structure should also be taken into account. Circuit design as the core technical part of security products, although not as clear and eye-catching as the structure and appearance, is related to the stability of the product's performance.
Because security products are often installed outdoors, along with the diversity of the installation environment, stability is the basis for product design considerations. Therefore, electromagnetic radiation immunity, lightning surge protection, rapid burst protection, voltage sags, and interruptions , anti-static, weather resistance, versatility, etc. have become unavoidable issues in the early circuit design of security, and different product circuit configurations have different focuses.
For example, because high-speed ball needs to meet the needs of various installation environments, the importance of its circuit design is self-evident, focusing on the motor driver board, isolated power board, control decoder board, character overlay circuit, and circuit board interconnection design. For example, the design of the movement circuit needs to consider that the camera is active at any time. Therefore, the durability of the cable in the active part needs special consideration, otherwise the cable may easily be broken and the like. Another example is the PTZ lens drive circuit requirements can adapt to a variety of electric pre-set lenses, but different lens manufacturers have a variety of product control and preset modes, in the circuit design needs to be fully compatible with all kinds of lenses.
For circuit board and power supply stability and heat dissipation, manufacturers will design a small fan, such as a Sony high-speed ball in the movement module is fixed by three screws, and two small fans on both sides of the circuit module designed for the circuit board Heat dissipation, and design the power board, control board, and code board at the bottom of the movement to enhance firmness.
In the prevention of external circuit interference, manufacturers have different designs, such as Huiyou in addition to the high-speed ball power supply board with a plastic card lock fixed, and in the backplane power connection designed anti-surge protection, wiring pipe at the waterproof plastic The United States and the United States have designed lightning protection terminals on the power board to ensure that the power supply can work stably without external influences.
"In addition, the circuit design should initially consider chip cooling and interface as well as wiring and layout issues," said Zhao Wei, deputy general manager of Shenzhen Langchi Xinchuang Technology Co., Ltd., which directly reduces the rate of product repairs and reduces service pressure. .
In order to avoid electromagnetic interference that may be caused when the product is installed too close, Tianjin Yaan Technology Electronics Co., Ltd. adds various electromagnetic radiation absorbing circuits inside the high-speed ball to minimize the mutual electromagnetic radiation between the products; and in order to avoid high-speed During the construction and installation of the ball, there is the problem of miswiring or not being able to get on the line. The plug-and-play connector is used in the high-speed ball to reduce the complexity of high-speed ball installation. In addition, due to the fact that the high-speed ball is installed in the light In a uniform environment, the displayed image may be deviated from time to time. In order to avoid repeated adjustment, the rationality of software design in the high-speed ball is very important, which can reduce the number of maintenance of the later products.
In addition to high-speed ball, DVR is also very concerned about circuit design. Because the DVR is prone to problems such as power burnout, unstable power supply voltage output, system initialization failure, and hard disk failure during the installation process, the circuit design is generally concerned with the design of the cooling fan, circuit board, power supply unit, and hard disk. For example, in terms of heat dissipation design, the fan settings, heater design, etc. will affect the stability of the circuit. Secondly, the size of the circuit board is related to the cost and energy consumption of the entire product. The circuit board is too large to cause many parts and contacts. The potential problems, stability will be affected, fewer parts, fewer problems, complex circuit fault detection will be more complex; for the power supply unit, the power supply circuit design some use of computer switching power supply, and some use of traditional transformer power supply The former is relatively small, expensive, and more energy-efficient. The latter is bulky, cheaper, and more energy-intensive. It has advantages and disadvantages in use. In addition, the number of hard disks, occupied space, and interfaces need to be considered.
Electromagnetic interference caused by excessive equipment installation is also one of the factors considered by DVR. According to Xu Jianxin, product engineer of Zhejiang Dali Science and Technology Co., Ltd., in order to avoid excessive interference, the DVR product's communication interface The over-current, over-voltage, and short-circuit protection circuits are designed for the network ports, power supply, and video connection ports, and they are different from traditional electroplating rubber materials. This can prevent interference and control costs.
The structural design relates to the installation and operation of the product. The security product must guarantee the realization of its basic functions and the resulting effects. The structural design of the product is also crucial to the efficient operation of the system. For example, whether the heat dissipation inside the product is in place and whether the material is used. Solid, easy installation and commissioning, flexible operations, etc., and different security products focus is not the same, so manufacturers also according to their own positioning and market requirements for different structural design.
Taking the intercom product as an example, the structure is related to the convenience of installation and construction, and it is also one of the important factors for the engineering company and users to measure intercom products. It is necessary to take into account the fixed mode of the intercom system, the wiring method, the destruction and coordination of the decoration, and the problem of the point pressure and the length of the line must be considered in the installation. In the bus and power supply technology, it is necessary to clarify specifications with the contractor and avoid The influence of light and hall structure on the signal control splitter. In addition, the intercom product in the structural part of the panel mirror impact resistance has a strict demand. According to Fermax's Chen Liqiang, in order to ensure durability, Fermax has adopted a high-strength and pressure-resistant design on the mirror surface. For example, Fermax's SKYLINE door machine can prevent solid materials with a diameter of 1mm or more from entering and resist 1.5kg weight. The impact, and in order to ensure the accuracy of the key, the key contacts are made of gold. The phone in the room pays attention to the thickness of the phone and the harmony of the indoor environment. For example, Guanlin's intercom product uses an ultra-thin 7-inch color LCD screen AH3 indoor design, the thickness is reduced by half compared to the past, not only lightweight But also conducive to production control costs.
Compared to intercom products that emphasize durability, the DVR emphasizes the convenience of operation and the stability of the system operation in the structure. Therefore, the panel design should try to meet the needs of users for humanity, speed, and simplification. Usually the manufacturers are on the panel. Some of them are designed to be concise as much as possible, basically in accordance with the public's operational design concept, with reasonable regional distinction, clear layout, simple button design and beautiful appearance. Considering that it is not easy to operate in a backlight environment, Dali’s products are running A faint blue light will be emitted, which is beautiful and practical. Considering the design of heat dissipation, manufacturers usually design a small fan inside a chassis to dissipate heat for different parts. In this regard, Dali Xu Jianxin also stated that the cooling holes should be opened reasonably, and the position of the fans also need to achieve convection. The shell of the machine uses a metal material with good heat dissipation and a low-power motherboard.
Unlike intercom products and DVRs, high-speed domes are mainly used outdoors, and the environment is more complex. Therefore, it is particularly critical in the structural design. Manufacturers are particularly careful in this regard. On the one hand, it is necessary to pay attention to the heat dissipation of the internal structure. For example, Sony’s high-speed ball is particularly solid in the structural design part. Five fans are designed inside. Convection can be formed between the inner layer and the outer shell, and cold start is supported. The high speed ball at Ya’an is An automatic temperature control system is set inside, and when the sensor detects that the working environment temperature reaches a certain level, the air circulation system will automatically open. In addition, in terms of installation and commissioning, the design of the DIP switches, new modules, anti-fall arresters and anti-off screws has been increasingly perfected. The manufacturers still need to strengthen the part, for example, in the installation of the movement should have a guide sign, the agreement and address should set the relevant logo, user-friendly settings, easy removal and so on.
In terms of structure, the high-speed ball has a higher requirement for the solidity of the shell, the material plumpness, and the volume. Manufacturers usually use cast aluminum materials for double-layer shells, while Sony's high-speed ball shells use cast aluminum materials. The shell hood is made of resin. The double shell adopts a ventilation design to facilitate internal heat exchange. In addition, Huiyou is The shell and the inner layer are separated, and the chassis and the fuselage are also separated. The inner layer and transparent cover are integrated. As for volume and materials, some manufacturers are small and exquisite, and some are biased.
Unique "appearance" and desire to incite consumption At present, the security industry still pays less attention to appearance design. Only upgrading the security system at the technical level can no longer meet the all-round development of the entire industry. In real life, the security system needs to ensure its functionality and at the same time, it must be in harmony with the surrounding environment, instead of being “a stereotyped and cold existence.†The exterior design will become an effective way for all security companies to increase the value of their products and to take an important position in the market.
How to break through the design bottleneck of the security system, starting from the appearance design without affecting the function of the product, improving the competitiveness of the product on the basis of excellent craftsmanship and stability, thus forming its own design style and concept. Therefore, Wu Jianzhou, the director of superior industrial design, has a profound understanding: "In today's product homogenization, excellent design has achieved the brand style of the product. Just like Apple, IBM, Philips, etc., each international brand has a unique appearance characteristics. ."
Such as intercom products will be installed in different styles of architecture, so the appearance of comparative study of materials, aesthetics and artificial body combined performance, and the surrounding environment to form a beautiful beauty. Usually manufacturers will choose more simple colors, fitting the tone of the building. In addition, the design of the mirror, the thickness of the phone, and the size of the screen are all parts of the appearance.
As a professional industrial design company specializing in security product industry design, for some security companies tailored to different industries and different users tailored product style design. For example, a manufacturer's DVR product needs to be used in a coffee shop. In order to meet the taste of the environment, the design is based on exquisite miniaturization. The side uses a bevel design, and the volume is smaller than before, and it is beautiful and easy to operate.
In the aspect of access control products, some customized designs have been made for some high-end customers, and different benefits have been generated through special designs and limited production. In addition, in the face of different markets, customers will also incorporate different elements, and incorporate Chinese cultural elements in the security products for the domestic market. For example, the fingerprint lock series will introduce the concept of retro design in the Dream of the Red Chamber and the riverside map of the Ming and Qing Dynasties. Users, the use of metal brushed minimalist design style, clear lines, focusing on visual effects and practicality.
Establishing exclusive styles and concepts, and establishing brand awareness In today's homogenization of security products, manufacturers must first clarify their own brand and philosophy positioning, so as to achieve in the process of product industrial design. As Fumankes's Chen Liqiang said, for the security industry, every company should have its own set of product industrial design and concept, and classify and maintain it. This is exactly what the current industry savings have created. Cognitive.
Finally, all aspects of industrial design should not exist in isolation, especially circuit design. As a core technology manufacturing part, it affects the complexity of the structure and the aesthetic appearance. Security companies may have different results because of their different emphasis and the designer's design differences. Therefore, industrial design should follow certain rules to avoid this arbitrariness.

Three-dimensional earthwork mat is a kind of three-dimensional mesh fabric made of polymer composites. The texture of the earthwork mat is loose and pliable, with 90% of the space to fill the soil and sand, and the root system of the plant can grow through the mat. The grass skin that grows hind makes net cushion, grass skin, soil surface firm together. The root system of plants can be reached under the surface of 30-50cm, thus forming a solid green composite protective layer.
Earthwork mat is a new type of earthwork synthetic material which is suitable for soil and water conservation. It can effectively prevent soil erosion and increase the green area and improve the ecological environment.
Function:
1.Alternative concrete, asphalt, slab stone and other slope protection materials, mainly used for highway, railway, river, embankment, slope and other slope protection.
2.The soil can be protected from wind and rain before it grows up
3.The compound protection layer formed after the plant grows can withstand high water level, and hurried water flow.
4.The cost of the project can be greatly reduced, and the cost is only 1/7 of the concrete protection slope and the slope of dry masonry, and 1/8 of the slurry masonry stone.
5.Due to high polymer materials and UV anti-stabilizer, it has high chemical stability and no pollution to the environment.
6.The construction is simple, after the surface level is flat, can be constructed.
Application
When construction can use small bamboo pole or small stick to wear in the whole coil net cushion, spread out to pull out stick, surround with bamboo nail, wooden nail or plastic nail, the nail distance is 30cm, each square meter 10 nails.
The length of nails is generally 15cm (from the ground), and the loose surface should lengthen the length of nails. When laying in the high slope, the length of the nails used should be longer than the length of the nail in the lower slope.
The topographic mutation or the terrain is more complicated, should be careful to keep the net pad level, and to increase the nail density.
Attention lap. The lap length is 2cm, the connecting pin should be nailed in, the density of the nail should double, and the upper layer of the lap joint should be close, without leaving the gap.
In the shape of the nail, the upper end of the nail should be greater than 2 times the diameter of the mesh, so that it can also have a vertical suppression effect.
Seed sowing depth should be according to the soil information, adjust measures to local conditions, grass should choose to suit the local climate conditions, root length, and rich grass seed, have long roots of perennial small shrubs in between is better.
Grass seed seeding depth should be in the mat, so as to enhance the effectiveness of the compound protection layer.
After seeding, the topsoil cover should be covered by covering the net. Don't expose the mat to the sun. However, it is important to take care of the seed germination and growth.
After seeding, the water content of the upper layer should be 40 to 50%.It is pressurized on top surface to help seed germination.
10.When the net mat is laid at the top of the slope, the vertical joint of the net cushion should be 60 degrees and buried 30cm in the soil. Bottom should be over 50 cm level, because of the side slope engineering of the water content was much lower than the lower layer, is not conducive to seed germination, gauze pad should be in the 20 cm suitable holding open a ditch, top place for irrigation.
11.The timing is the key to the whole project (when used on the slope), usually in the first three to four months before the rainy season. Let the turf have some time.
Notes:
1.Cannot be used as the surface protection material.
2.Only the surface planting grass slope, cannot use as deep reinforcement material.
3.When used for river slope protection, the construction should be completed in the first three months of the rainy season. In order to ensure the high water level above the grassy slope is firmly formed.
