Do you remember this divine song?
"Zhang Shichao, where did you put my house keys?"
The smart speakers, smart TVs, refrigerators, TVs, and washing machines on the other side of the door are "crying out for food." If you can't get through the door, no matter how good the smart products are, you can't use them.
So first, you need to solve the problem of getting in the door.
The rapid development of smart door locks in recent years is partly due to the need to replace traditional keys. Of course, you may have often heard such questions before:
I heard that...smart door locks are difficult to use and fingerprint unlocking recognition is slow.
I heard that...smart door locks are not safe enough , and can be easily cracked by fingerprint stickers, network hijacking, and Tesla coils.
I heard that...smart door locks are not durable enough and the batteries need to be replaced every three months.
Today, China's smart door lock market has also seen a "blowout" development, with annual shipments reaching 10-12 million units and continuing to grow rapidly.
Represented by products from brands such as Kaadas, Aqara, Zhongyuguan, Huichuang, Yuntian, Tianyou, and Tianwang, smart door lock products are constantly being iterated and optimized, and have become a must-have in the home, just like color TVs, refrigerators, and washing machines.
A large number of smart door lock brands have chosen Cypress solutions . Why is that?
PSoC 6: It understands your problems and how to solve them
In order to realize multiple functions such as fingerprint recognition, voice control, capacitive touch, wireless connection, etc., smart door locks often require at least 3-4 different chips to work together to make the door locks truly smart.
But this brings up three problems:
1. How to control hardware costs with multiple chips?
2. How to complete the development and debugging work for different chips?
3. Now that the function is realized, how can the power consumption be controlled?
In the past, the more complex the functions of a smart door lock, the more complex its development and design.
Today, we have released the IoT-AdvantEdge development platform, a smart door lock solution with PSoC 6 as the core. It not only knows what your challenges are, but also knows how to help you solve the difficulties, and truly uses a chip to take on the responsibility of a door lock.
The PSoC 6 series products include: basic PSoC 62 , PSoC 63 with BLE wireless connection , and PSoC 64 with security upgrade .
PSoC 6 has many widely recognized advantages, which can be summarized as follows:
-
High integration: Fingerprint recognition, voice control, capacitive touch, screen display, wireless connection, RTC and other functions that traditionally require 3-4 chips to implement have now been integrated into PSoC 6, which means a cost reduction of up to 30%-40%.
-
High performance: PSoC 6 frequency can reach 150MHz, and has 8K Icache, fingerprint recognition speed can be achieved within 200ms, and can support up to 100 sets of fingerprints. Among them, the Cortex M4 core is adapted to the mainstream fingerprint recognition Match algorithm on the market.
-
Low power consumption: For battery-powered devices, power consumption is always the biggest challenge. PSoC 6 uses a 40nm process and can consume as little as 35uA in deep sleep mode (capacitive touch wake-up, BLE broadcast).
-
Supports BLE and BLE Mesh connections: This ensures data connectivity while minimizing power consumption.
-
Ecosystem support: The PSoC 6 solution has been dual-certified by Xiaomi Smart Home and Alibaba Tmall, and can be integrated into their smart home ecosystem without any barriers.
PSoC 6: Security is a top priority
A lock's primary duty is
"
safety
"
.
Smart lock manufacturers have solved physical vulnerabilities such as Tesla coils and X-rays, while BLE communication and future Internet communication security will be handled by PSoC.
From the day it was born, in addition to the existing TrustZone hardware security of the Arm core, PSoC 6 also provides basic encryption engines such as basic symmetric encryption, asymmetric encryption, HASH algorithm, random number generator, ECC, RSA, etc., which are the basis for building IoT products.
The advanced PSoC 64 has upgraded security features such as Secure Boot and TEE to effectively prevent network eavesdropping and theft during data communication, providing as much security support as possible from both software and hardware aspects.
Corelink: From Bluetooth to WiFi, we will continue to make intelligence a reality
Smart door locks, like other products such as sweeping robots, smart lighting, and smart air conditioners, have an important application scenario and requirement:
the command must come first, even if the person is not there
.
Whether it is the homeowner himself or the visitor authorized by the homeowner, they can unlock or change the password through WiFi remote control.
Therefore, in addition to Bluetooth, realizing WiFi connection of smart door locks has become another major function of smart door locks. Moreover, unlocking can happen anytime and anywhere, which means that WiFi connection must meet the requirements of being online at any time, secure connection, and low power consumption .
Security is left to PSoC 6. However, if you want to implement WiFi communication for smart door locks, you also need the CYW43012 Wi-Fi & Bluetooth 2-in-1 Combo chip, which is the best partner of PSoC 6.
CYW43012 adopts 28nm ultra-low power design, and the cloud keep-alive always connected power consumption is less than 140ua, which can ensure the service life of 6 dry batteries for more than half a year.
In addition, CYW43012 is compatible with traditional WiFi protocols such as 802.11 a/b/g/n/ac, allowing your smart lock to always be online .
Just click to unlock remotely.
Development support: not only want to use, but also plug and play
The original intention of releasing the IoT-AdvantEdge platform is to enable IoT design to
be completed in one stop
.
Before PSoC 6, it might take up to a year for a smart lock to go from development, design, board making to prototype and functional testing. Now, this time has been greatly shortened to just three months .
In the IoT-AdvantEdge development platform, we provide a free development tool - ModusToolbox. It integrates cloud services including Amazon AWS and RTOS, provides rich API interfaces, underlying HAL and PDL, and secure library, allowing developers to truly plug and play.
If you are developing with PSoC 6 for the first time, the IoT-AdvantEdge platform also provides many design solutions and cases for reference at any time. In Cypress's IoT developer community, developers from all over the world will also provide you with support and help.
Today, the smart door lock market is still in a competitive period of "war among princes". If you want to be one step ahead, you must speed up the product development cycle and strike a balance between safety and performance to be invincible.
