With the routine of community and office management, intelligent access control system has become more and more popular. QR code intelligent access control terminal is an access control system with QR code as the identification carrier. It encodes the traditional card information into a QR code graphic, and reads and verifies the QR code picture through an authenticated mobile phone. All door opening actions, door opening methods, greeting switching, graphic display, etc. are controlled by the cloud. After scanning the QR code, the mobile phone wechat will send it to the cloud. After the cloud processing is completed, it will be sent to the terminal for completion. The mobile terminal does not save the user's private information, but uploads the authentication information left to the cloud app + applet during cloud registration. All authentication and pairing information is saved in the cloud, and the terminal is not easy to crack

RFID card reader is a self-developed RFID tag card reader application scheme. Ultra high frequency (UHF) RFID technology is the most advanced fourth generation automatic identification technology in the world. It is widely used in retail, warehouse management, personnel identification and other occasions. Compared with low frequency (125k ~ 134.2k), high frequency (13.56MHz), UHF RFID reader has longer reading and writing distance, strong confidentiality, faster card reading speed and better directionality. However, although the existing card readers in the market realize a single card reading and writing function, they are facing a wide range of commercial and industrial applications, and have not been able to provide integrated products, such as power supply, communication networking, protection, compatible design, etc。

With the continuous improvement of market requirements for gas meter technology and accuracy, ultrasonic measurement technology has been widely used, and the development of ultrasonic gas meter has gradually expanded from industry to civil field. Because the composition of domestic gas source is relatively complex and the installation environment is relatively bad, it affects the accuracy and stability of ultrasonic measurement and restricts the rapid development of ultrasonic technology. The as6040 ultrasonic metering chip of Ruigan and the external expansion amplification circuit are adopted to successfully solve the problem of serious ultrasonic attenuation and insufficient signal input in harsh environment, help customers quickly realize gas design and accelerate the mass production and listing of gas meters.
