Access Control Built on ARM64 Architecture

When developing projects for access controlgate machines, face recognition, card swiping, and other access devices,engineers will consider whether to use an ARM32 or ARM64 hardware and softwarearchitecture. From the perspective of software app development, ARM32 isbecoming increasingly rare, so it is recommended to adopt the ARM64architecture.

Starting from Android 9, Google has supported 64-bit architecture development. Currently, Dingchang's embedded boardssuch as RK3566, RK3568, RK3588, and RK3576 already support ARM64 hardware andsoftware development.

In terms of access control algorithmdevelopment, Dingchang's newly developed AI algorithm platform API now supportsMegvii face algorithms, encryption chips, and AI license plate recognitionalgorithms for license plate access gates, which can handle two commonapplication scenarios: pedestrian access and vehicle access respectively.

For projects or applications involving access control devices and algorithm development, the hardware configurationdoes not need to be too high. According to Dingchang's actual customer projectsthat have been implemented, the RK3566-configured boards can meet most developmentneeds.

1. Camera development requirements: For face recognition or license plate recognition, RK3566 can support up to 8million pixels. It can connect to a single-channel camera (monocular orbinocular) and also support 2-channel MIPI CSI camera access.

2. Onboard Omron relay: Under the Androidsystem, it can control card swiping modules, face recognition, fingerprints,etc., for verification and access. Next, the relay controls the two states ofthe electromagnetic lock (closed and open) to manage access control. The sameapplies to gate motors.

3. LED fill light: Onboard 4-channel LEDfill light interfaces, including 3 channels of 12V constant voltage and 1channel of 0.5A constant current, which can better adapt to needs insemi-outdoor or outdoor scenarios.

4. POE support: In some access controlproducts such as door stations where it is inconvenient to pull power cords,the POE interface can support both Ethernet and power supply needssimultaneously.

5. Expansion support: Supports USB (type-c)power supply, TTL, RS485, 232, I2C expansion interfaces, as well as onboard6-channel USB, 4-channel serial ports, 1-channel I2C that can connect to touchscreens, 1-channel infrared remote control, and other peripheral function interfaces.

The above is just a summary by Dingchang's editor of some of the actual development needs for access control and otheraccess projects using the RK3566 platform.
