Viewing the Development Trend of Modular Data Centers from *Policing Cloud Big Data

Silent data speaks
Case 1: The theft occurred in a college’s dormitory. Several computers and mobile phones were stolen. The local authorities immediately inquired about the surrounding video surveillance and peripheral bayonet videos. According to the time of committing the crime, the suspected vehicle passing time of the bayonet was calculated and locked quickly. Suspected vehicles, according to the license plate number, the police quickly locked the trace of the suspect. In the "big data combat platform", enter the license plate number, the vehicle's trajectory at a glance, and then collide with the "electronic fence" information that can capture the mobile phone signal, who was on the car after the incident, and soon there is result.
Case 2: A foreign license plate full of goods, imported from a high-speed exit into the urban roads, the drivers are eager and swift, ignoring the traffic warning signs that the trucks are forbidden to enter the elevated roads in the urban areas, and they slammed into a certain road. Elevated. Unexpectedly, only five or six kilometers of traffic, the vehicle was quickly stopped by *. According to the local * introduction, thanks to the intelligent video surveillance system, this car will illegally send illegal information to the nearest * police mobile phone within 10 seconds when it illegally enters the elevated portal. In this way, * can be law enforcement in time.
* Characteristics of police cloud big data
Today, the use of big data to help * successfully solve cases is too numerous to mention. The above are just two common cases. With the development of information technology, the information-led policing system has been promoted to help solve challenges easily. * A large number of policing data and social resources data are collected in the system database. The policing cloud is used as a carrier of big data and has the typical characteristics of big data:
The first is massive, large enough to "amount of data that cannot be managed with the current technology";
The second is diversity, and the types of data are complex, including not only traditional formatted data, but also web logs, videos, pictures, geographic location information, etc. from the Internet. Unstructured data accounts for 75%-95% of the total amount of stored data. These unstructured data cannot be processed with current technology.
The third is low value density and high commercial value. Getting data from large amounts of low-quality, low-value data is costly. Take video as an example. The data that may be useful during continuous and continuous monitoring is only one or two seconds.
The fourth is the speed of processing. The frequency and frequency of data generation are very fast and require real-time processing; this is fundamentally different from traditional data mining techniques.
Policing Cloud Big Data Challenges Infrastructure
With the deepening of the construction of the “policing cloud”, the number of information system data is increasing, and there is an explosive growth trend. The information systems built with the traditional construction model are becoming larger and more complex, and the pressure for management and operation and maintenance has also increased. The data center infrastructure is developed following the development of the upper layers. The traditional data center architecture pales in comparison with the data center construction requirements in the era of policing cloud big data.
First, the power density is low: the traditional data engine room is usually in the form of air supply, supporting the power density is low, in the application of high-density servers, prone to local hot spots, resulting in equipment failure. Therefore, the traditional air distribution system is no longer applicable to the new data center for policing cloud big data.
2. Inefficient operation and maintenance: There are 6 ICT operators in a provincial office, who need to be responsible for ICT, video, system security, and informatization project management. Only 1 person is responsible for the operation and maintenance of the computer room infrastructure, and can only pass through. The manual patrol method has very low efficiency, even equipment failures, and it only took half a day for services to respond to the situation.
III. Difficulties in Capacity Expansion: Traditional data houses have been solidified since the beginning of construction. It is very difficult to achieve future capacity expansion. For data houses that need to be expanded, plans must be put forward at the beginning of design to embed the necessary infrastructure at one time. .
New modular architecture emerged
In this context, if a modular architecture is adopted, the above problems can be solved. The Modular Data Center is mainly targeted at data centers in the city bureaus, districts and counties, and police stations in Ping'an City to provide them with the hot water and power needed for data center infrastructure. The program integrates power supply and distribution systems, row-level cooling systems, cabinet systems, monitoring systems, and integrated wiring systems. It adopts a modular architecture, factory prefabrication, and rapid deployment to help build a reliable, green, and intelligent data center.
First, high power density: Modular data center adopts row-level air-conditioning approach to heat source, which can achieve higher power density than traditional refrigeration systems, and because of the decentralized arrangement characteristics of row-level air conditioners, it can support different implementations in different micro-modules. The demand for power density more meets the demand for power density that is different for different services.
Second, to simplify the operation and maintenance: Modular data center has a unified operation and maintenance interface, interface interface is easier to manage, by a unified modular equipment provider is responsible for solving all the professional connectivity problems involved in the infrastructure, fundamentally eliminate the different professional Pushing each other happens. Second, the modular data center has intelligent features, such as battery capacitor fan warning, battery shutdown and other functions, making operation and maintenance easier.
Third, the flexible expansion: modular data center to achieve pre-integration of the various subsystems in the factory, greatly simplifies the installation of the project, reduce on-site deployment time, and to achieve the flexibility of the architecture does not need to determine the entire room as the traditional machine room After planning, the infrastructure will be unified. Modularized data centers can be prefabricated along with project construction, planned according to business needs, and deployed step by step in stages. Similar to the way of building blocks, they can be expanded with the needs of the system.
Figure 1 Application of Medium-sized Modularized Data Centers in the Computer Room of Provincial Offices and Municipal Offices
Figure 2 Application of Small Modular Data Centers in District and County Computer Rooms
Figure 3 Application of Micro Modularization in the Police Station Room
The modular data center is not only applicable to the policing cloud application of the industry*, but also applicable to other industries such as finance, transportation, and energy. The latest ICTresearch report shows that the modular data center market is increasing year by year. In 2015, Huawei Modular Data Center led the industry with 17% market share. (Figure 4 below)
Figure 4 Market share of each brand in China's modular data center market in 2015 (Source: ICTresearch 2016)

The modular data center's features of practicability, intelligence, and flexibility are more suited to the needs of today's big data. High-density, low-power data centers will become the mainstream. It is believed that the modular data center will gradually replace the traditional construction model and protect the data centers of all walks of life.

CNC Milling

In general, computer numerical control milling machine (CNC) machining is a deductive manufacturing technique that programs 3-axis linkage, complex to 5-axis linkage, drives milling cutters to remove layers from solid blocks called blanks to produce finished parts. CNC milling is one of the main types of CNC Machining, which uses cutting tools that rotate at a speed of several thousand to tens of thousands of revolutions per minute (RPM) to precisely remove materials to obtain parts with complex surfaces. In addition to milling, CNC machining is also equipped with drills, boring tools, thread cutters and other tools to complete different part features at once. CNC machining produces parts based on a computer-aided design (CAD) model that is sent to a CNC machine through computer-aided manufacturing (CAM) software.

CNC Machining centers developed from CNC milling machines. The biggest difference compare to CNC milling machines is that the machining center has the ability to automatically exchange machining tools, by installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in a single clamping device to achieve a variety of machining functions.

CNC milling accuracy

CNC milling centers and high-Precision Machining centers. Ordinary machining center, resolution of 1μm, maximum feed speed of 15 ~ 25m / min, positioning accuracy of about 0μm. High-precision machining center, resolution of 0.1μm, maximum feed speed of 15 ~ 100m / min, positioning accuracy of about 2μm. Between 2 and 10 μm, with a ± 5 μm more, can be called precision grade. FCE equipped with different grade and different size CNC milling center. Take in to account into both economic and quality in parallel.

CNC Finishing surface treatment

Post-processing is the final step in the CNC machining process. In a quick guide, we offer a lot of surface treatments to complete your final parts and get them to meet strict specific requirements. It should be noted that in CNC machining, post-processing is in optional, as the quality of the machined parts is already very high.

Anodized

The anodizing process allows the part to obtain excellent corrosion resistance, increasing the hardness and wear resistance of the surface. Anodizing is also the most common pre-painting treatment, which can help the painted surface to obtain good adhesion. We typically apply two types of anodizing in our production: Type II, corrosion resistant; Type III is thicker, adding a layer of wear resistance. Both anodizing processes can achieve a variety of color effects.

Polishing

Grinding polish, it offers the fastest turnaround parts and does not require post-processing. The surface finish of the grinding part is equivalent to 125 um in Ra, and the requirements can be increased to 63, 32 or 16 um Ra. Minor tool marks may still be visible on the last part.

Powder coatings

Powder Coating is thermoplastic powder spraying directly on the processed part. The sprayed parts are then baked in an oven to form a durable, abrasion- and corrosion-resistant plastic coating. In the powder coating process, its color, brightness, surface roughness can be customized.

Shot blasting

Shot peening is the high-speed spraying of beads of different hardnesses and sizes onto the surface of the part. To get different textures and brightness of the surface. Since the surface has been hit by similar forging beads, the hardness and wear resistance of the surface have also been enhanced.

Design of CNC machining

CNC machining is a universal machining process, especially parts that can be cut and machined can be achieved through CNC, from simple shape shapes to complex curved structures. However, as with every manufacturing technique, CNC machining has some design limitations. We break them down as follows to ensure that your products are optimally designed to better fit the CNC machining process.

General Tolerance

When designing parts, the size of each part is different according to the application environment, working conditions, etc., and the requirements for the machining accuracy of the workpiece are also different. Although CNC machining can achieve very high machining accuracy, we should also be aware that demanding machining accuracy and accuracy (strict product tolerances) usually mean Longer production times and higher costs. If a specific tolerance is not specified in the product design, we recommend choosing at the following levels.

The highest precision of our equipment is 0.001, and the recommended most precise machining requirements do not exceed +/-0.005mm

Interior angle

All internal vertical edges of our products need to have rounded corners instead of right angles. This is because the tools used in CNC milling are cylindrical, which means they cannot produce inner right-angled edges. The fillet required by this process is called the inner corner fillet. When designing parts, the larger the inner corner fillet, the more efficient the production process. Because of the larger fillets, larger diameter milling cutters can be used to increase milling speed, and fewer swaps can be made to improve accuracy.

Undercut

Undercut cannot be machined with standard milling cutters, so the use of retract slots for parts should be avoided when designing CNC machined parts. In particular, for non-standard inner contour shapes, customized machining tools are required, which will greatly increase processing time and costs. Secondly, if undercut can not be avoided, due to the limited length of cnc tools, the undercut can not be too deep. If they are too deep or the location is difficult to reach, they will not be able to be produced because the CNC tool cannot reach the machining location.

Chamber wall thickness

CNC machining requires your part design to meet minimum wall thickness requirements. In general, it is recommended to choose the thickest possible and avoid very thin or characteristic walls. This is because CNC tools processing thin-walled parts will cause vibration deformation, which may cause interruptions or damage, and the size is out of specification. The standard minimum wall thickness for CNC machined metals is 0.030" (0.76 mm) and for plastics is 0.060" (1.5 mm).

Thread

When designing parts, it is useful to choose the largest possible thread size because smaller taps have a higher risk of breaking during production. If possible, avoid using deep hole threads as they lead to higher production costs, especially when custom tools are required.

Metal

In principle, materials with high hardness are easier to process because better processing accuracy can be obtained, but they are limited by the hardness of processing tools, so the hardness of the generally recommended parts is 8 ~ 60HRC, and for metal materials, the hardness is greater than stainless steel Followed by cast iron, followed by copper, and finally aluminum, while the processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials. Fast production time.

Polymer

Although CNC can process thermoplastics, the material properties of polymers still have many difficulties for CNC processing. First, due to poor thermal conductivity, many thermoplastics melt or bend when in contact with CNC milling machines or drill bits. Secondly, the processing of plastics, because the hardness is low, the size accuracy caused by the knife during product clamping and processing is not high. For those parts that do not have special requirements for the strength and hardness of the metal, thermoplastics can provide a cheaper alternative.

Cost optimization of machined products

Simplify product design

Simplifying product design while taking into account functionality usually saves production time and reduces production costs. Because the manufacture of complex structures and surfaces often requires complex longer passes, more layering to obtain the same fine contour quality. This means higher production costs.

Reduce cutter changes

Using the same milling machine machining features, larger and same internal fillets, can reduce the number of tools used to reduce machining time. For example, if a workpiece needs a 10mm end face milling cutter to process some features, it also needs a spherical milling cutter to process a curved surface, and a 2mm milling cutter to process a fine groove, which will require repeated tool changes and reduce the machining efficiency

Proper material selection

The choice of raw material for machining can have a significant impact on production time and costs for CNC machining. If possible, choose a material with good processability, such as brass or aluminum. For those applications that do not require metal hardness and strength, CNC machining of engineering plastics like PMMA and ABS also helps to reduce costs because the material blank is cheaper, and the processing efficiency is higher.

Tolerance and wall thickness

Higher tolerances and thinner wall thicknesses also increase THE CORRESPONDING CNC machining costs, as it takes time to achieve higher precision cutting. If your product or component can accept a larger size range, choose a lower tolerance to reduce production time and costs. The same is true for wall thickness: a larger wall thickness margin should be chosen.

Choice of surface treatment

Surface treatment is often the final stage of the CNC machining process, which can also affect the cost of your entire project. Choosing less surface treatment for your part or product can lead to better time and cost efficiency. FCE can recommend to you how to optimize the surface treatment to balance the conflict between cost and quality according to your final needs.
