Din Rail Power Supply air conditioners work in turn and set the temperature?

With the continuous development of network information technology, the environmental parameters in the computer room where the server is stored are also becoming more and more important. Some small and medium-sized computer rooms keep the temperature inside the equipment room within a certain range. Not only one air conditioner is installed, but also a spare air conditioner is stored. The purpose is to prevent malfunction of the air conditioner in operation or other reasons. It is necessary to turn on the backup air conditioner. However, it is impossible for the computer room management personnel to stay in the computer room for 24 hours. In order to reduce the burden on the computer room management personnel, the air conditioner intelligent switcher can solve this problem well.
The air conditioner switch can control two air conditioners at the same time to realize functions such as air conditioner caller self-start, timed temperature control switch, failover, and fault alarm. Applicable to computer room, outdoor base station, archives, warehouse and other places. Its principle of using infrared code to switch air conditioners makes the device compatible with all brands of air conditioners on the market.
First, the air conditioner switch concept
The air conditioner dual-machine switcher is a kind of intelligent air-conditioner controller, which can detect and control the running state of the air-conditioner, and control according to the preset air-conditioner operation, shutdown and combined behavior, with automatic call start function, cycle switching, temperature control, Timing control, relay output and other functions. The purpose of protecting equipment, saving energy and reducing consumption, improving the efficiency of computer room management and extending the service life of air conditioners has been achieved. This product is widely used in civil, small and medium-sized computer rooms, communication stations, UPS machine rooms in all types of cabinets. Mainly used for switching control of two air conditioners.
Second, the advantages and Din Rail Power Supply

Universal infrared code learning function
Some uncommon air-conditioning brands that do not support built-in infrared codes can use the infrared code learning function to control air conditioners.
Call self-start
When the air conditioner encounters a power outage and then calls, the air conditioner shutdown cannot be automatically started, and manual startup is required, which brings great trouble to the management. When the power is detected and the call is detected, the infrared signal can be automatically sent to turn on the air conditioner without human control. The call start time can be customized.

Microsoft exposes four VR touch studies to let you touch VR world like "Number One Player"

Spielberg's "The Number One Player" is a hit, and the male player can interact with the virtual world through touch-sensitive gloves and the X1 somatosensory suit. Beyond the movies, how to get a sense of touch in virtual reality and how to interact more naturally is a topic of current concern to researchers. Recently, Microsoft's research team has released four latest virtual reality research results: CLAW, Haptic Wheel, Haptic Links, and Canetroller, which can better help users “touch” objects in virtual scenes and enjoy the wonders of the virtual world.

VR

Although VR 360 and AR have made tremendous progress in the past 30 years - they have been able to provide users with a fantastic visual and 3D audio world, but when we reached out and touched those virtual objects, the illusion would be instantly disillusioned. Only air came.

There are many reasons why virtual touch is difficult to achieve. People who have watched movies know that eyes and ears can be deceived by a movie of 24 frames per second, but the sense of touch is very different and it is more complicated. Part of the challenge of implementing virtual tactile sensations comes from hardware. In the laboratory, designing a handheld device suitable for individual user wear is often difficult. Many prototype devices today are only capable of simulating specific sensations, such as texture, temperature, or weight, and such devices are often unattractive. More sophisticated mechanical technologies may result in equipment that is too expensive, too large or too fragile to appear in the consumer market.

The Microsoft research team has been exploring how to use existing technology to simulate the generation of multiple haptic sensations on a handheld VR controller, enabling users to touch and grab virtual objects and feel the fingertips slide across the surface of the object. Their dream is to allow users to interact more naturally and more with the virtual digital world.

CLAW

CLAW is the first new multi-function haptic controller developed by the Microsoft research team. Using a single motor, CLAW extends the VR controller concept to a versatile haptic feedback tool. The CLAW has a unique robotic arm that simulates force feedback when the user's hands are holding hands and turning their fingers (see below).

CLAW
(Left) Configuration and components of CLAW; (right) CLAW simulates user grabbing and touching the surface of a virtual object

As a multi-function controller, CLAW contains all the functions of a normal VR controller (thumbs and joysticks, 6DOF (Degree of Freedom) control, index finger triggers) and various touches that are enabled for the most common hand interactions. Rendering: grab objects, touch virtual surfaces, and receive force feedback.

What's unique about CLAW is that it can adjust haptic rendering by sensing the difference between the user's grip and the virtual context environment. When the user tries to hold the virtual object (as shown below), the device creates resistance between the index finger and the thumb, simulating the feeling of the object being held. The force sensor embedded in the index finger holder allows the user to "feel" the different materials of the object by changing the feedback of the motor.

If the user holds the handle and makes a pointing gesture (as shown below), CLAW provides a touch feeling. As the fingertip moves toward the surface of the virtual object, the CLAW generates resistance, pushing the finger back and preventing it from penetrating the virtual surface. In addition, when the index finger slides along the virtual surface, the voice coil mounted below the tip of the index finger generates a small vibration to mimic the surface texture of the object.

VR

Perceiving the power exerted by the user can also help the user interact with the virtual object. For example, in a virtual painting program, the program can adjust the intensity of the brush by sensing the strength of the user's hand.

Haptic Wheel

To further simulate the tactile experience of the index finger on the virtual object's material and surface friction, Microsoft has also developed another new haptic controller - the Haptic Wheel. The driving wheel used by the Haptic Wheel simulates the touch of the finger with the surface of the virtual object by moving up and down, and simulates the shear forces and sliding sensations generated when the user slides along the virtual surface by rotating.

When the user touches the surface of the virtual object, the wheel will rise and touch the fingertip, and then begin to rotate to simulate the friction between the fingertip and the surface of the virtual object.

VR

Figure 2: (Left) When the user hovers over the surface of the blue area of the wheel, the rendering engine moves the appropriate wheel surface under the finger; (middle) When the user approaches the black area in the virtual environment The rendering engine turns the wheel so that the same material as the black edge approaches the finger; (right) When the finger is hovering over a small black surface, the rendering engine adjusts the gain of the wheel so that the finger touches correctly The edge of the feeling.

The wheel of the device is replaceable and can contain various physical tactile elements to provide users with different feelings when they explore the virtual environment. When a user explores a virtual environment, the rendering engine passes the appropriate haptic sensations to the fingers based on the environment. For example, in a virtual card game, when the user touches a card, a poker chip, or a table, the device rotates the wheel to present a proper texture perception under the fingertip. As the user slides along the surface, the wheel rotates under the finger to create shear and sliding sensations.

Haptic Links

Another problem that is difficult to solve in tactile exploration is how to simulate the use of both hands in VR or AR applications. For example, with both hands holding a box to feel its size, or use your hands to feel the tension on the bow.

VR
Tools that simulate the user's hands in a virtual environment

Haptic Links consists of several types of connectors that provide different stiffness perceptions between two handheld VR controllers. Haptic Links can dynamically change the power felt by the user's hands to support the rendering of various types of two-handed objects and human interactions, making the controller behave like a two-handed tool. They can constrain the specific degree of freedom or direction of motion between the controllers, and can also be set within a range of stiffnesses to simulate different frictions, viscosities, or tensions. Through these methods, Haptic Links makes the interaction in the VR scene more realistic and gives people an immersive feeling.

VR

Microsoft made three prototype devices for Haptic Links. Each design has its own compromise and advantages, making it the best fit for a particular application. The Chain prototype device (in Figure 5) uses a highly articulated chain consisting of ball and socket elements. A powerful cable runs through the chain and connects to linear actuators on each end. The movement of the push rod motor controls the tightness of the chain and further controls the user's operating space.

VR
3 different prototype devices for Haptic Links

Layer-Hinge (figure 5 left) uses a ball joint to adjust the controller's rotation and uses a hinge to control the distance between them. Its advantage is that it can selectively lock the freedom of movement of the controller. In addition, it can control the friction force of each joint relatively accurately, so that the device simulates a continuous range of stiffness values in the hinge and ball joints.

The Ratchet-Hinge (figure 5 right) uses a similar ball joint at the bottom of the controller, but instead of the hinge with a double ratchet, it can independently brake inward or outward movement. When two ratchets are engaged, the gears are fixed; when both ratchets are disengaged, the gears can rotate freely. When a ratchet is disengaged, the gear can move freely in one direction but not in the opposite direction. Directional selectivity enables unique force feedback interactions.

Haptic Links can improve the perceived realism of objects requiring two-handed operation in a virtual environment without overly affecting the normal interaction of the two controllers.

Canetroller

The "traditional" virtual reality experience is strongly visualized in nature, so visually impaired people usually cannot use it. The Canetroller prototype device developed by Microsoft Research hopes that visually-impaired people can also use a walking stick for blind guidance in virtual environments.

Canetroller offers three types of feedback: (1) physical resistance from wearable, programmable brakes - simulation of a virtual cane hitting a virtual object; (2) vibrational haptic feedback - simulation of a cane striking an object or across a variety of surfaces (3) 3D auditory feedback - simulates the sound of a real world cane.

VR
One blind person is using Canetroller

Canetroller allows low vision and blind people to perform simulated blindness training in different virtual spaces, reducing their risk in the daily environment. Microsoft hopes that this work will motivate researchers and designers to design more effective tools to make VR more inclusive, taking into account the different groups around the world.

The Microsoft research team's innovations in virtual touch, on the one hand, hopefully stimulate the imagination of other researchers. On the other hand, they hope to bring new applications and hopes for special groups such as visual impairment and help them improve their quality of life. In addition, researchers hope that these innovations will encourage more consumer products to use haptic rendering technology. I believe tactile products will soon make VR and AR products more realistic and immersive.

以太幣“挖礦”: 能耗黑洞!

期待從比特幣風口中分一杯羹的人們湧向“礦廠”,投入到“挖礦”掘金的熱潮中。與此同時,以太幣挖礦”的驚人耗電量引人矚目。

能源價格比較服務網站PowerCompare.co.uk研究顯示,2017年用在比特幣“挖礦”上的電量超過29.05太瓦時(1太瓦時為1億度電),超過了全球159個國家的年均用電量。愛爾蘭全國(477萬人口)一年的用電量也只有25太瓦時的電力。

  近日又有報導稱,雲南昆明某小區內有住戶由於進行比特幣“挖礦”,導緻小區內大面積跳閘,變壓器被燒毀,400多米的電纜因此受損。

  挖個比特幣,為什麼這麼耗電?

  集成電路功耗是根本原因

  “比特幣挖礦機本質上是一種特殊的計算機。”清華大學信息技術研究院副院長曹軍威在接受科技日報記者採訪時說。

  這種特殊的計算設備是如何挖到比特幣的呢?

  在比特幣的世界裡,大約每10分鐘會記錄一個數據塊。所有的挖礦計算機都在嘗試打包這個數據塊的同時完成提交任務,而最終成功生成這個數據塊的人,就可以得到一筆比特幣報酬。礦機的算力越強,“挖礦”速度越快,挖到比特幣的概率也就越高。

  現在比特幣“挖礦”正在從“礦工”單打獨鬥進入“組隊挖礦”時代,也就是通過“礦池”來“挖礦”。假如你的礦機算力佔整個“礦池”算力的五分之一,如果“礦池”一天能挖到5個比特幣,那麼你可以分到1個比特幣。

  在爭分奪秒的“挖礦”競爭背後,電費是不可忽視的重要成本。有“礦工”算了一筆賬:按照礦機每天運行24個小時可以挖出0.0018個比特幣來計算,556天可以挖出一枚比特幣。他的礦機功率為1350瓦,功率1000瓦的礦機每小時約用一度電,兩台礦機每天耗電量32.4度,每天電費16.8元。也就是說,挖到一枚比特幣要花費9367元。

“從根本上來講,這是集成電路的功耗問題。”曹軍威告訴科技日報記者,從硬件層面來看,電路本身就會消耗電能,而比特幣挖礦機對算力的要求又比較高,在進行大規模“挖礦”時礦機又比較集中,加起來功耗自然就大了。

  吸電“狂魔”不只有挖礦機

  其實,除了比特幣“挖礦”,計算設備耗電量驚人的新聞十分常見。

  比如超級計算機。報導顯示,天河二號超級計算機每年產生的電費接近1億元人民幣,相當於一座中小城市一年的耗電量。 “神威·太湖之光”超級計算機每年耗電量約為15兆瓦時,相當於3個清華大學的用電量。耗電量依然驚人。

  再比如數據中心。中國數據中心節能技術委員會秘書長呂天文在接受科技日報記者採訪時介紹,2016年中國數據中心總耗電量超過1100億千瓦時,超過了三峽大壩2016年全年的總發電量,且與2015年時相比增長11.7%。

“數據中心的耗電包括4個部分,IT設備、供配電系統、新風製冷系統以及其他。”呂天文告訴科技日報記者,其中IT設備耗電量佔總耗電量的50%左右,新風製冷系統佔35%—40%左右,供配電系統佔15%—18%左右。

  呂天文介紹,PUE(Power Usage Effectiveness,電源使用效率)是衡量數據中心能源效率的重要指標,它是將數據中心總設備能耗除以IT設備能耗得出的數值。目前國內數據中心的平均PUE水平在2以上,也就是說非IT設備的耗電量超過了IT設備本身的耗電量。

  “在數據中心,大量能耗發生在非IT設備上,很多電被白白浪費掉了。”呂天文告訴科技日報記者,供配電系統和製冷系統在節能方面有很大潛力。比如,新風製冷系統佔整個能耗的35%—40%,進行優化調整節能改造後,就可以節約10%—20%的能耗。從全國范圍來看,就可以省出100億到200億元電費。

  突破摩爾定律限製成為關鍵

  但呂天文承認,在數據中心中,IT設備的節能才是最根本的。因為IT設備能耗占主要部分,而且供配電系統、新風製冷系統都是為IT設備服務的。

呂天文給科技日報記者算了一筆賬,假如IT設備的功率為1000瓦,那麼就需要同時配備功率為1000瓦的供配電系統和功率為1000瓦的新風製冷系統,每小時總耗電量為3000瓦時。如果IT設備將能耗降到500瓦,就需要同時配備500瓦的供配電系統和500瓦的新風製冷系統,每小時總耗電量為1500瓦時。

  這意味著,一旦IT設備能耗降下來,整個數據中心的能耗也會顯著下降。

“但現在的數據中心節能改造大多關注供配電系統和製冷系統等非IT設備,這其實是個悖論。”呂天文告訴科技日報記者,一旦數據中心投入使用,就很難再對IT設備進行改造,因為IT設備宕機會帶來巨大損失。所以現在通常鼓勵數據中心在設計建設之初,就盡量採用性能更好的、更為節能的IT設備。

  那麼IT設備的能耗又是怎麼產生的?呂天文解釋說,數據中心的IT設備能耗“大戶”為網絡存儲設備和服務器,其中網絡存儲的能耗佔60%左右。以前機械式硬盤的能耗就比較高,現在數據中心越來越多地使用SSD固態硬盤等網絡存儲技術,可以顯著減少這方面的能耗。

“無論是比特幣'挖礦',還是數據中心,或者是超級計算機,本質上其功耗問題都與最底層的集成電路有關。”在曹軍威看來,隨著芯片技術的發展,單位面積集成電路上的器件越來越多,功能越來越複雜,與此同時單位面積集成電路的功耗也越來越高。

  曹軍威介紹,除此之外,從軟件層面來看,其功耗又與算法的設計、軟件的效率有關。從系統層面來看,要看好多IT設備搭建的集群採用的是什麼網絡結構、是否高效。而從環境因素來看,又涉及散熱、製冷等系統。

  至於如何從根本上讓這些計算設備不再如此耗電,長遠來看,恐怕需要通過量子計算和新半導體材料等來突破摩爾定律的限制,讓計算設備更高效、更節能。
