Lying in bed can also know who to visit the front door, which is Nanjing University of Posts and Telecommunications students based on Internet of things and wifi transmission to develop a SmartGuard smart guard mobile phone software, can be described as lazy people do not miss.
Ma Pengyu, the chief planner of the wisdom guard, is a sophomore in Nanyou Communication Engineering. According to him, this software connects the mobile phone with the security door in the home. As long as the visitor presses the doorbell, the user's mobile phone immediately pops up a prompt: "Do you want to check the video screen?" When the user confirms the view, the user can see the visitor's face through the camera installed on the security door. If you are willing to open the door, the user can simply let the security door open automatically by just pressing it on the phone.
What is the principle of this? Ma Pengyu went on to say that the Internet of Things is divided into three layers: the perception layer, the transmission layer, and the application layer. The doorbell first triggers the module and then remotely accesses the wifi accessed by the router to achieve remote control of the access control. Among them, the wifi module is integrated with the camera, programming to capture video information, and send the video stream to the terminal (smartphone, tablet or PC) via wifi.
As far as the mobile phone is concerned, after the user installs the software, he needs to enter an account number and password to log in each time he opens the software. Then just run in the background. If someone rings the doorbell, the phone will automatically pop up. If there is no one at home or does not want to hear the doorbell, the software can also switch between doorbell and infrared. If you turn off the doorbell reminder, the door's infrared will automatically open the detection, and when someone closes, it will trigger a reminder.
However, since it is infrared sensing, the mutual touch of objects and the movement of pets are also inevitably systematic false alarms. In this regard, Ma Pengyu frankly said that it still needs further improvement.
It is reported that Ma Pengyu team also designed a set of smart home systems, the future of the family will realize the center of the access control to build a small network architecture, to achieve a variety of home appliances in mobile phones, computers and web-based control and data transmission, including home temperature , humidity control, gas alarm, television, audio and other electrical switches, timing and volume control, etc., a system all buttoned.
