关于智能门锁应用的知识以及未来的设计趋势

欢迎来到Silicon Labs（亦称“芯科科技”）制作的2021展望－芯科播客（Podcast）系列，与我们一同探索智能家居和消费应用市场的发展。本次播客由Silicon Labs物联网细分市场经理Sean Snell主讲，他专职负责智能门锁（Smart Lock）客户，将以问答的形式来分享更多关于智能门锁应用的知识以及未来的设计趋势。

Q： What are the new things that you‘re seeing drivethe growth in the smart door lock space？你看到有哪些新事物推动智能门锁的增长？

Sean：Yeah good question. So， to begin kind of one of the easiest answer to that is justincrease market adoption， you know smart home is starting to ramp as we’ve expected for a long time. But door locks are a little bit of a lagging indicator in that were the first purchase that usually occurs in any kind of smart home life cycle is a hub of some kind of either an Alexa， Google， apple HomeKit， like the HomePod， and then after that usually the second purchase of some kind of lighting fixture， like some light bulbs.好问题。最简单的答案就是市场的采用率增加，你知道智能家居已经开始像我们预期的那样快速增长了。但是门锁是一种滞后的指标。在任何一种智能家居的生命周期中，经常出现的第一种购买商品是某种Alexa、Google或Apple HomeKit设备例如HomePod智能音箱之类的产品，然后通常第二次购买某种照明设备如灯泡。

But one of the earlier purchases kind of after those two initial ones is door locks so we‘re kind of seeing this ramp up his door locks are finally being kind of integrated into the smart home ecosystem， as well as a lot of apartment blocks using door locks， now smart door locks can give them versatility.

在这两个最初的产品之后则是智能门锁，所以我们看到门锁最终被整合到了智能家居生态系统中，还有很多公寓楼都在使用智能门锁，现在智能门锁能给用户多功能性。

So as we’re kind of moving through 2021， we just expect the market to start increasing adoption of this. We‘re moving from leading to kind of mainstream and that’s kind of a big part of it. On top of that， all the ecosystems are making big pushes into smart homes these days. Apple recently had a whole section of their keynote devoted to their new HomePod mini kind of featuring the entire smart phone ecosystem and how they‘re kind of bringing it in.迈入2021年，我们希望市场开始越来越多地采用智能门锁，我们正在走向主流角色，这是其中的一个重要部分。除此之外，近期所有的生态系统都在大力推进智能家居。苹果在最近的主题演讲中，专门介绍了他们新的HomePod Mini产品，以整个智能手机生态系统为特色，说明如何将其引入智能家居。

So you know， when these tech giants sorts of start to make actual strides breaking into this market and to kind of pushing this market forward then.A variety of peripheral equipment also began to develop， so that’s kind of going to start driving a lot of business in this market. More tractions because these tech giants are bringing a lot of attention to them so that is a big part of itfor door lock specifically. Wi-Fi has really become a big growth market as well Wi-Fi historically struggled in this just because of our constraints reallywith the Wi-Fi being a little bit to power hungry to be A feasible products， alot of companies to get around this by having it as some kind of socket thatplugged into the wall.当这些科技巨头开始真正的大步进军这个市场，然后推动这个市场的发展。各种外设设备也开始发展，因而推动这个市场上的大量业务。更具吸引力是因为这些科技巨头吸引了很多关注，特别是在门锁方面，Wi-Fi已经成为一个巨大的增长市场，但Wi-Fi确实是一个有耗电需求的产品，很多公司通过插电来解决这个问题。

So there will be a secondary communication from the Wi-Fi radio， which was plugged into a wall socket to the lock itself. With recent improvements in battery life constraints or battery life consumption that hasallowed for the Wi-Fi radios actually moved into the lock which makes the user experience a little bit easier and kind of make it gives them one less thing that they have to buy and install one of the things to keep their eyes on so that‘syou know has shorten the battery life， a little bit because the Wi-Fi still ismore power hungry than other protocols. But was also allowed for kind ofan easier installation process， which is a big focus for this for this market.

所以，从Wi-Fi无线电（插在墙上的插座）到锁本身会有二次通信。随着最近对电池寿命限制或电池寿命消耗的改善，Wi-Fi实际上已经可以安装到门锁内，这使得用户体验更加轻松，并减少了他们需要购买和安装的设备。这就是你知道的电池寿命会缩短的原因，有一点是因为Wi-Fi仍然比其他协议更耗电。但也允许安装过程更简单，这是这个市场的一个重点。

And then finally security， so this is kind of more of a shuffling around and all ofiot again. There’s a lot of security regulations coming into play now with SB-327 and a couple of the other regulations really kind of starting to have an influence on the market.最后是安全性。现在，有很多安全条例正在与SB-327一起实施，还有其他规范开始对市场产生影响，改变这个市场的运作方式。

Q：Those are really kind of changing how this market is acting and how we take part in and how our customers end up delivering products？安全性显然是Silicon Labs非常有实力的立足点，这些新的法规确实要求门锁的安全性。你能和观众分享更多信息吗？

Sean：Yeah so a lot of these regulations and for context， some of the big ones are SB-327， which is a California state bill. And a couple others that are all cominginto the market， they have certain requirements that are very relevant to the door lock market big to secure device. On the exterior of a house， so it has a potential to be approached or interacted with by someone who is not inside your house or in a secure area.是的，很多法规中较受关注的是SB-327，这是加利福尼亚州的法案与物联网密切相关。另外则是一些进入当地市场的要求，对门锁市场的安保设备非常严格。因为在房子的外部，设备有可能被人接触或与之互动。

A lot of this includes some temper detection， so this is more so for the kind of our customers when they get the devices， knowing that it hasn‘t been tampered with kind of as the temper detection suggests， but then also for security bug. The under lying requirements behind them is that they need to verify when someone is going into them and checking their code and requirements are going to require devices to confirm the identities and make sure that these users， that are changing the code actually have permission to modify the code.很多安全机制包括篡改检测（temper detection），对于我们的客户来说，当他们得到设备时即便知道设备没有被篡改，但也有安全漏洞。背后的底层需求是，当有人要接入设备或代码时，需要验证且确认身份，并确保正在更改代码的用户实际上有修改代码的权限。

On top of that there’s also security storage so understanding that accessing the code is going to need certain keys and making sure that those keys are stored in a safe manner. One that can be replicated in a way， in both public and private keys that kind of work in pairs to make sure that the devices as secure as we can currently achieve with them with the technologies today and then finally just tamper detection so understanding.此外，还有安全存储，访问代码需要某些密钥，并确保这些密钥以安全的方式存储。这是能够以某种方式复制，在公共密钥和私钥中，这种密钥成对工作，以确保设备安全。目前已经可以通过当今的技术来实现。

Having the device be physically secure and that hasn‘t been tampered with through either voltage attacks through heat attacks any kind of physical stimulus althrough any kind of modifications electrically so all of these are kind of building requirements in the security regulations that apply to this market.

让设备在物理上是安全的，而且没有通过任何形式的攻击如电压攻击（物理刺激或通过任何形式的电攻击）来篡改它。这些都是来自于极为关键的安全性要求。

And kind of our goal with security， especially our kind of recent is to satisfy all of these and to add on top of that， so bringing in a couple of other elements. With secure identity and security station， a lot of the big security features that we have specifically target these requirements.我们的目标是不断持续改进产品的安全性，因此引进了安全身份（secure identity）和安全站点（secure station），我们特别针对行业需求开发许多安全特性。

Q：As you mentioned， regulations is definitely one way to have a customer change in their product lines. As a customer I’m looking for something that’s changing the way it interacts with my house oradding a new feature so I‘ve heard a lot of changes in the industry through the standards and ecosystems， for example， I’ve heard recently about Project CHIP and OpenThread， Bluetooth mesh and Z-wave long range. Can you comment on how these are specifically going to impact new door lock design？如前所述，法规是让客户改变其产品线的一种影响力。客户正在寻求改变与家居互动的方式或添加新功能，因此关注了很多与标准和生态系统，例如Project CHIP（现改称Matter）、OpenThraed、蓝牙mesh，以及Z-Wave远程技术的进展。你能评论一下这些技术对门锁设计的影响吗？

Sean：Yeah so Product CHIP （Matter） is a good example let‘s start there so Product CHIP （Matter）， especially is kind of is very important to alot of our customers， because of the opportunity it provides to work with both several major ecosystems， you know Apple and Google are both working very hardon shipping.

是的，Project CHIP（Matter）是一个很好的例子，让我们从这里开始，Project CHIP（Matter）对我们的很多客户来说是非常重要的，因为它提供了与几个主要的生态系统合作的机会，你知道苹果和谷歌都在非常努力的推动此标准。

As well as the kind of the overarching end device market where our manufacturers kind of get an easier design process， so you know getting from the ideation to actual design. On home depot or Walmart’s floor where they can sell it and then not having to worry about building specific designs for you know your apple is ecosystem or Google‘s ecosystem and sidewalk.

制造商在终端设备市场获得更简单的设计过程，简化从构思到实际设计。他们可以在家得宝或沃尔玛出售产品，而不必担心具体的设置，因为支持苹果、谷歌或Sidewalk。

On the other hand， remote access is a benefit of Z-Wave and is really beneficial to the door lock market because you know the access points on your property aren’t just limited to your physical house the physical building itself. But there are exterior access points that you want to control as well， such as your front gate or you know your garage door.

另一方面，远程访问是Z-Wave的一个好处，对门锁市场大有助益，因为你知道你的房产上的接入点不仅仅局限于你的实体房子，实体建筑本身。有一些外部接入点需要控制，比如前门或者车库。

Q：

Yeah you‘d mentioned the tech when they joined together forsomething like Project CHIP will do good to the industry. But beyond that sowe’ve talked about security regulations and the standards can you talk aboutsome new innovative features for door lock designs？

是的，当你提到科技巨头为了Project CHIP（Matter）标准联合起来的时候，肯定对于这个行业大有助益。除此之外，我们还讨论了安全规则和联盟标准。你能进一步分享有关门锁设计的创新功能吗？

Sean：The door lock market as a whole， outside of smart things you know it‘s a pretty stable market. There’s not been a lot of innovation there for a while， but with the introduction of smart things， it‘s opened up a whole range of new possibilities. You mentioned the user approach one so for those around user approaches， the door lock automatically opens so it makes the transition easier. It’s kind a similar thing， if you forget to lock your door， the door itself automatically blocks. Those are two really interesting experiences. there‘s a couple of technologies that are being developed around this that provides kind of distance measurement. That we’re Silicon Labs is investigating and kind of putting some resources into.

门锁是相当稳定的市场，有一段时间没有太多的创新，但是随着智能技术的引入，它开辟了一系列新的可能性。你提到了用户体验，作为用户，当他们接近门锁时，门锁会自动打开，这一过程就非常简化了。类似的情况，如果忘了锁门，门就会自动关上，这是两个非常有趣的体验，业内有一些技术正在围绕着用户体验发展，可以提供距离测量。Silicon Labs正在研发并投入了许多技术资源，从而为客户带来新的功能。

Another innovation we have which isinteresting is the addition of hall effect sensors. But on top of that there‘s a new kind of series of features that include understanding if the doors physically open or closed to provide extra information. You know those are someof the major innovations in high levels that have come to the market and we’re really interested in seeing how our customers managed to take advantage of the main drive value to the end consumer themselves. I believe that there are locks that are realizing this value now and we hope that it will become more popularas people realize that that‘s a big frustration.

另一个很有趣的创新是霍尔效应传感器的加入，提供一系列新的特性，包括了解门是开着还是关着的，以便为用户提供额外的信息。这是一些已经进入市场高水平的创新，我们非常有兴趣看到我们的客户如何利用这些创新，并为最终消费者创造价值。我相信现在有一些锁正在实现这种价值，我们希望随着人们意识到它的好处，它会变得更加流行。

Q：Can you share some of the Silicon Labs solutions that you see will help the customers when working on this challenge with doorlocks？请分享一些你认为对客户有帮助的Silicon Labs解决方案，我们做了什么来帮助解决智能门锁的挑战？

Sean：yeah so in general， you know one of the biggest benefits of SiliconLabs that we’re a protocol agnostic company so regardless of the protocol that our customers come to us with， we really have a solution for them. On Wi-Fi specifically， as that‘s kind of a big initiative for us this past year， with the acquisition of Redpine is more cost efficient for our solutions.

总的来说，Silicon Labs最大的好处之一是不管客户需要什么协议，我们都能提供解决方案。在收购Redpine后，我们有了新的Wi-Fi产品线，这是我们在过去一年里的一项重大举措，使我们的解决方案更具成本效益。

In addition， we have BG Bluetooth product series， FG proprietary protocol and MG Multiprotocol product series. It depends on the environment involved in the customer’s product to decide how to give the customer design suggestions.另外我们有BG蓝牙产品系列，FG专有协议和MG多协议产品系列，这取决于客户产品所涉及的环境来决定如何给到客户设计建议。

To a potential customer or a current customer that‘s looking to kind of expand to anew protocol or a new line of business， if they want to operate in a new ecosystem or bring a Wi-Fi product into their portfolio. And also we have some reference designs on github， people can use as a starting point for door locks.

如果潜在客户或当前客户希望扩展到新的协议或新的业务，或是他们想在新的生态系统中运营或将Wi-Fi产品引入他们的产品组合中，我们在Github上有一些参考设计，客户可以把它作为门锁设计的起点。

We actually have both an OpenThread and a Product CHIP （Matter） as references. If anyone wants to go check those out， we will give those are quick plugs to help evaluation.

实际上我们现在有OpenThread和Project CHIP（Matter）的参考解决方案，如果有人感兴趣的话，我们可以提供给一些快速的插件帮助评估。
