Problems solved by technology

[0002] With the development of science and technology, people's requirements for anti-theft alarm technology are getting higher and higher. In order to meet people's growing needs, various anti-theft alarm products emerge in an endless stream on the market, such as anti-lost devices, fingerprint locks, combination locks, etc. However, conventional products have the following disadvantages: 1. Large size and poor portability; 2. When some anti-theft products are far away from users, they cannot give alarm instructions to users in time; 3. Some products are complicated to operate and need to memorize passwords, A series of operations such as setting fingerprints will cause inconvenience to users
[0003] In recent years, portable anti-theft alarm devices using light sensors have gradually entered people's field of vision, and alarms are made by using changes in light intensity. However, at present, the effect of anti-theft alarms is not ideal. The problem of false positives

Embodiment 1

[0037] like figure 1 As shown, the present embodiment provides an alarm method based on a light sensor and a magnetic sensor, including the following steps:

[0038] S101: When the magnetic sensor detects the magnetic field generated by the magnetic object, the light sensor starts to work and measures the ambient light intensity data in real time;

[0039] S102: When the light sensor detects that the intensity of the ambient light changes from dark to bright and exceeds the preset threshold, and the magnetic sensor does not detect the change in the magnetic field strength generated by the magnetic object after the set time, the first alarm indication is performed ;

[0040] S103: When the light sensor detects that the ambient light intensity continuously changes from dark to bright beyond the preset threshold and from bright to dark beyond the preset threshold within the set threshold time, that is, from a dark environment to a bright environment , When entering another dark e...

Embodiment 2

[0050] like figure 2 As shown, the present embodiment provides an alarm device based on a light sensor and a magnetic sensor, including: a control unit, a light sensor, a battery and an alarm indication unit, characterized in that:

[0051] A magnetic object for providing a magnetic field;

[0052] The magnetic sensor is used to detect the magnetic field provided by the magnetic object and the change of the magnetic field strength, and transmit the detection result to the control unit in real time;

[0053] The light sensor is used to detect the ambient light intensity of the device, and transmit the light intensity signal to the control unit in real time;

[0054] An alarm indication unit, used for alarm indication to the user or the surrounding crowd;

[0055] The control unit is used to receive signals from the optical sensor and the magnetic sensor and control the magnetic sensor, the optical sensor and the alarm indication unit to perform corresponding work according t...

Embodiment 3

[0070] Embodiment 3 of the present invention provides a wallet based on a light sensor and a Hall sensor, including a wallet body and an alarm device based on a light sensor and a Hall sensor located on the wallet body. The alarm device is installed on one side of the wallet, and the magnetic object is installed on the other side of the wallet body.

[0071] Please refer to as Figure 4 As shown in the schematic diagram of this embodiment, its working principle is: when the thief takes out the wallet from the user's bag or pocket, because the thief is eager to transfer the wallet, on the one hand the thief may put the stolen wallet in as soon as possible. In your own pocket or bag, at this time, the light sensor detects that the ambient light intensity continuously changes from dark to bright and exceeds the preset threshold, and from bright to dark exceeds the preset threshold within the set time, that is, the wallet changes from one to the other. One dark environment enters...

Abstract

The invention provides an alarm method and device based on an optical sensor and a magnetic sensor. The magnetic sensor and the magnetic object are respectively arranged on two sides corresponding to the opening and closing structure; when the magnetic sensor detects the magnetic field generated by the magnetic object, the light The sensor starts to work and measures the ambient light intensity data in real time; when the light sensor detects that the intensity of the ambient light changes from dark to bright and exceeds the preset threshold, and the magnetic sensor does not detect the magnetic field generated by the magnetic object after exceeding the set time When the intensity changes, the first alarm indication is given; when the light sensor detects that the ambient light intensity continuously changes from dark to bright and exceeds the preset threshold, and from bright to dark exceeds the preset threshold within the set threshold time, Carry out the second alarm indication. The invention can accurately indicate the alarm and avoid the occurrence of false alarms.
