1 Single female safety guard door stopper

摘要

The present invention relates to a one-woman safety guard door stopper, which can detect an object by using the infrared sensor to detect the part that emits infrared light to the Arduino infrared distance sensor and the light that the transmitted infrared rays return to. It is a wireless device that can automatically recognize smart devices by means of a beacon and transmit necessary data. When an object is detected for a certain period of time or more, a notification can sound on the smart device, and the door stopper tells the user that the user is an unspecified person. If it is determined, it can be automatically turned on and off through the Arduino circuit to solve the problem of an unspecified person intrusion using the CCTV blind spot, thereby solving the problem of the existing unspecified person intruding using the CCTV blind spot. did it In other words, the present invention is an infrared sensor, smart It is a wireless device that can automatically recognize a device and transmit necessary data. When an object is detected for a certain period of time, the beacon is configured in the form of a small chip so that the smart device can be notified when an object is detected. An alarm configured in a circular shape so that an alarm can sound without delay in case of an alarm, an LED indicator configured as a light bulb so that the LED indicator blinks when data is transmitted to the beacon to sound an alarm, and the user is determined to be an unspecified person It is composed of a door stopper composed of a rigid bar that can be opened and fixed to automatically turn on/off through the Arduino circuit. Therefore, the present invention makes it possible to detect an object using the characteristic of detecting the light that emits infrared rays to the Arduino infrared distance measuring sensor by the infrared sensor and the transmitted infrared rays return back ‹š, and a smart device by a beacon. It is a wireless device that can automatically recognize and transmit necessary data. When an object is detected for a certain period of time, a notification can sound on the smart device. If the user is identified as an unspecified person by the door stopper, the It has the effect of solving the problem of an unspecified person intrusion using the CCTV blind spot by solving the problem of intrusion by an unspecified person using the CCTV blind spot by allowing the user to turn on and off the CCTV camera.
