Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

With the development of economy and technology, terminal equipment has been widely used in people's daily life, such as smart phones with a wide range of uses. For any terminal equipment, it has the function of short-distance communication with other wireless communication devices. , based on this principle, the terminal device can judge whether the device is still near the terminal device by monitoring the wireless communication signals of its surrounding devices in real time, so as to realize real-time anti-theft monitoring of personal belongings.

The embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings. Figure 1 is a schematic flowchart of a method for real-time anti-theft of personal belongings provided by the embodiment of the present invention. The method includes:

Step 11: Install a wireless communication device on the personal item to be monitored.

In this step, the wireless communication device installed on the personal item sends out wireless signals.

Step 12: Using the wireless communication function of the terminal device, establish a wireless communication link between the personal item and the terminal device.

In this embodiment, the terminal device specifically includes: devices such as smart phones, notebook computers, or tablet computers;

Specifically, the wireless communication function may include: bluetooth communication, infrared communication, or wireless local area network communication.

Step 13: The terminal device performs real-time signal detection on the personal belongings.

In this step, the process of real-time signal detection is:

When the terminal device receives the wireless signal sent by the personal item, extract the name and signal strength of the wireless communication device from the wireless signal;

First, compare whether the name of the wireless communication device is the same as the name of the bound wireless communication device on the terminal device; if they are the same, then further compare whether the signal strength exceeds a preset signal strength threshold.

In this embodiment, since the strength of the signal received by the terminal device is directly related to the distance between the two devices, when the monitored personal belongings gradually move away from the terminal device, the distance increases, and the signal strength received by the terminal device will increase. will decrease; when the personal item exceeds the safe transmission distance, the terminal equipment can’t even receive the wireless signal sent by the wireless communication device, so this embodiment can set a signal strength threshold based on this principle to judge whether the personal item is The distance between the item and the end device.

Step 14: When the received signal strength is lower than the preset signal strength threshold value, the terminal device performs an automatic alarm operation.

In the specific implementation process, it can be realized by detecting the signal strength index RSSI. First, a threshold value of the signal strength index RSSI is preset according to the protection range of the personal items to be monitored; If the threshold value of the set signal strength index RSSI is less than, it means that the portable device is far away from the protection range covered by the terminal device, and then the terminal device can perform an automatic alarm operation.

Here, the automatic alarm operation may specifically include: automatic vibration, automatic ringing, automatic playing of specific music, or automatic calling or sending a short message to a set user.

In addition, in a specific implementation, the terminal device can further filter and eliminate short-term sudden changes in received signal strength, so as to improve the reliability of the anti-theft system and prevent early warning and missed alarms. Specifically, it can be implemented by setting a signal filter module in the terminal device.

In addition, in a specific implementation, when the user needs to monitor a personal item, the power of the terminal device and the wireless communication device on the personal item can be turned on respectively, and the anti-theft software installed on the terminal device is run, and the anti-theft system operates normally; when the user does not When the personal item needs to be monitored, the power supply of the wireless communication device can be directly turned off.
