Anti-lost device

Abstract

The invention provides an anti-lost device applied to people, objects in a determined relative space anti-lost range and other anti-lost objects. The anti-lost device comprises an identification device and a monitoring device. The identification device comprises a passive RFID label, and the monitoring device comprises a passive RFID label reading or reading-writing module, a reminding module and a power module. The reminding module is triggered to make a response when the reading module monitors or does not monitor the passive RFID label, two kinds of monitoring devices can be combined for use, the identification devices also can be related or paired for use, and reminding modes comprise sound, light, actions and the like, wherein linked reminding is carried out. The anti-lost device can be made to the shape of a bracelet and other wearable objects or can be made to the shape of a card or a button so that the anti-lost device can be conveniently carried, and the anti-lost device can comprise a back adhesive face and other attachable structures or bolts and other fixed connection structures to be conveniently fixed on other devices. Due to the passive RFID label, the identification device does not need a power source, cost is greatly lowered, reliability of the anti-lost device can be enhanced, the anti-lost effect is ensured, and the service life of the anti-lost device is obviously prolonged.

Description

technical field

[0001] The invention belongs to the field of electronic products, in particular to an anti-lost device. Background technique

[0002] Theft is the most troublesome problem in the field of public security in our country. With the rapid development of our country's economy, crimes involving theft are always in a state of frequent occurrence. Some families bring untold pain. Due to the existence of these situations, some innovative individuals and units have invented a large number of anti-lost devices, including those used for property, used by children and the elderly. With the emergence of wearable products such as smart bracelets, some newly invented anti-lost devices have also been made into wearable products in the form of bracelets in recent years. The above-mentioned inventions and innovations all adopt wireless transmitting devices (some also have receiving devices), and use power sources, generally powered by batteries, and the power of batteries is...

[0020] An anti-lost device for infants and young children in the application scene of obstetrics and gynecology in hospitals

[0021] The identification device adopts passive 915M UHF RFID tags, and the effective recognition distance is generally more than 5 meters. It is made into the shape of a bracelet and worn on the hands of infants and young children; Meters or more, the recognition distance between the two is 5-8 meters, it is made into a square box and fixed above the outside of the ward door, connected to the mains through the power module, always on, and uninterrupted monitoring is performed once every 2 seconds. The reminder adopts sound, and there are two kinds of sounds: one is a peaceful "baby is in and out", if this sound is detected during 8:00 to 21:00, the other is a loud "see the baby quickly" , use this sound to remind from 21:00 to 8:00 the next day. When an infant wearing a bracelet-shaped identification device enters and exits the ward door, the monitor...

[0025] A property anti-lost device for personal portable application scenarios

[0026] The identification device adopts passive 13.56 MHz RFID tags, and the effective recognition distance is generally 0.5-1.0 meters. They are made into card-shaped and adhesive-backed card-shaped respectively, which are put into wallets and glued to mobile phones respectively; the monitoring device adopts corresponding passive RFID tags. The tag reader has an effective recognition distance of 0.5-1.0 meters, and the recognition distance of the two is 0.5-1.0 meters. It is made into a square box with a groove and fixed on the waist belt (near the side of the wallet and mobile phone bag). The power module is connected to a button battery, and it is turned on when it is necessary to prevent theft. When it is turned on, the frequency of 1 second is continuously monitored, and vibration is used to remind. When the wallet or mobile phone equipped with or pasted with the identification device cannot ...
