In the fast-paced modern life, people are often troubled by various trivial matters, and the situation of being forgetful occurs frequently. Whether it's losing important documents, wallets, or being unable to find children or pets, it can bring us a lot of inconvenience and annoyance. The emergence of smart anti-lost devices provides an effective solution to these problems and has become a powerful assistant in people's lives.
The Working Principle of Smart Anti-lost Devices
Smart anti-lost devices mainly use positioning technologies such as Bluetooth and GPS. Take the Bluetooth anti-lost device as an example. It establishes a Bluetooth connection with smart devices such as mobile phones and monitors the distance between them in real time. When the distance between the item and the mobile phone exceeds the preset safe range, the anti-lost device will immediately send out an alarm to remind the user that the item may be lost. This method of judging the distance based on the Bluetooth signal strength has the characteristics of low power consumption and sensitive triggering. For example, the common Bluetooth 4.0 anti-lost device works in this way. It is specially designed for devices such as iPhone 4S and iPad. It is lightweight and portable and can be conveniently applied to the anti-lost scenarios of items such as mobile phones, wallets, and keys.
The GPS anti-lost device relies on GPS positioning and GSM signals and can achieve real-time and accurate positioning. Even if the item is beyond the effective range of Bluetooth, as long as it is in an area covered by GPS signals and the GSM network, the user can accurately obtain the location information of the item through the mobile phone application. However, GPS positioning consumes a large amount of power, and there are still certain technical problems in indoor positioning at present.
Diverse Application Scenarios
Travel: A Reassuring Travel Companion
Losing luggage during a trip is a headache. The travel lock integrated with an anti-lost chip has emerged as the times require. The moment the customs lock is buckled into the suitcase, it starts to protect the safety of the luggage. At Pudong Airport, this kind of travel lock protects more than 2,000 pieces of luggage on average every day. For business people who often forget the location of the consignment note, they can check the luggage positioning and the status of the customs lock at the same time with just a tap on their mobile phones, as if installing "double memory" on the suitcase.
Shared bicycles have also become more reliable because of smart anti-lost devices. When cycling in the city, the newly added circular reflector at the rear wheel of the shared bicycle under the shadow of the plane trees is actually an anti-lost product disguised as a safety device. When cycling enthusiasts forget the parking location of the vehicle, it can retrieve the lost vehicle through satellite positioning. Test data shows that this kind of device has increased the retrieval rate of bicycles by 47%, making forgetfulness no longer a "pause button" in life.
Daily Life: A Thoughtful Life Assistant
In daily life, people often encounter the situation of not being able to find items such as keys and access control cards. Now, hanging a smart keychain on the key ring can easily solve this problem. For example, an office worker who 補辦 access control cards on average twice a month. Since using the smart keychain with a BLE5.2 chip device, the function of "automatic alarm when the mobile phone is more than five meters away" has saved him from the embarrassment of waiting for the locksmith in the cold late night. The statistics of the community property management show that the smart keychain has reduced the frequency of residents asking for locksmith assistance by 62%.
For parents, the safety of their children is always the top priority. On the park lawn, the miniature locator embedded in the children's shoes is flashing green. The young mother only needs to slide the mobile phone screen to check the real-time distance between her child and herself. By setting the alarm threshold at 20 meters, it can not only give the child enough space to explore but also firmly maintain the safety bottom line, continuing the concept of two-way anti-lost, so that "looking for the child" is no longer the main theme of parent-child outings.
Office Scenarios: An Efficient Office Guarantee
Smart anti-lost devices also play an important role in office scenarios. In the conference room, the pen with a positioning function is changing the working habits of people in the workplace. An administrative director of an enterprise revealed that due to the use of this kind of pen, the loss rate of quarterly meeting materials has dropped from 18% to 3%. Colleagues who always complained that their pens were stolen no longer have to worry about this. Its buzzer function for finding items makes the disappearance of important items a "false proposition".
The Remarkable Advantages of Smart Anti-lost Devices
Low-power Design with Long Battery Life
Most smart anti-lost device products adopt a low-power design, and the battery life can reach 6 to 12 months. For example, some products using the ST17H66 chip have a standby current of only 20 - 30μA, and a button battery can last for at least half a year in standby mode, greatly reducing the trouble of users having to charge frequently. It is more environmentally friendly with green energy conservation.
Waterproof and Dustproof, Adaptable to Various Environments
Mainstream smart anti-lost devices have good waterproof and dustproof performance, and the protection level reaches IP67. This means that they can cope with situations such as daily rain. Just like the case of the customs lock mentioned in the literature, it can still work normally after the water spray test, ensuring its reliability in various complex environments.
Data Encryption, Safe and Reliable
In order to protect the privacy and data security of users, smart anti-lost devices usually adopt advanced encryption technologies, such as AES - 128 encryption technology, to ensure that the positioning data is only visible to the user, effectively preventing data leakage and making users feel more at ease when using them.
As a practical smart device, the smart anti-lost device has already played an important role in people's lives, helping us solve many troubles caused by the loss of items or the wandering away of people. It is believed that in the future, with the continuous improvement and innovation of technology, the smart anti-lost device will, with more excellent performance and richer functions, become an indispensable part of people's lives, allowing us to completely bid farewell to the trouble of "being forgetful" and enjoy a more convenient and reassuring life.
