An intelligent anti-lost system and method

Abstract

The invention discloses an intelligent anti-lost system and method. The system comprises an anti-lost device, a Bluetooth communication module, an alarm module, a Wi-Fi module, a button battery and a central controller. The Bluetooth communication module, the alarm module, the Wi-Fi module, the button battery and the central controller are all arranged on the anti-lost device. The anti-lost device is connected and communicated with a mobile terminal through a communication protocol. In a short-distance monitoring condition, only a low-power Bluetooth working mode is started, and in a long-distance monitoring condition, the low-power Bluetooth working mode is preferentially started, and a Wi-Fi working mode is started when the Bluetooth communication range is exceeded or false alarms and alarm failure occur due to unstable signals, so that power is saved and the service life of equipment is prolonged, the effective distance of monitoring is increased, and the anti-lost device in a safe distance can be effectively and accurately monitored. In addition, when a distance between a mobile phone and the anti-lost device is beyond the safe distance, the alarming of the anti-lost device and the mobile phone end is supported at the same time, and the mentioned bidirectional alarm mechanism can comprehensively inform a user.

Description

technical field [0001] The invention belongs to the technical field of intelligent equipment, and relates to a simple anti-lost intelligent system and method, in particular to an intelligent anti-lost system and method based on Bluetooth low power consumption and Wi-Fi applications. technical background [0002] Valuable items such as mobile phones, wallets, and suitcases in daily life are easily forgotten, lost or stolen, resulting in property loss. At present, the monitoring of anti-lost devices on the market is mainly based on Bluetooth signal detection. However, the safe distance of the Bluetooth signal is short, and the signal is easily blocked in a complex environment. For example, when there is a wall barrier, the monitoring signal is unstable, which is likely to cause false positives and false positives. In addition, the general anti-lost device only alarms the user when the item is lost on the anti-lost device, but the anti-lost device does not alarm when the mobi...

Problems solved by technology

However, the safe distance of the Bluetooth signal is short, and the signal is easily blocked in a complex environment.

For example, when there is a wall barrier, the monitoring signal is unstable, which is likely to cause false positives and false positives

In addition, the general anti-lost device is only in the case of missing items on the anti-lost device, and the mobile phone will alarm to remind the user, but in the case of the loss of the mobile phone, the anti-lost device will not alarm
