Embodiment 1

[0031] figure 1 It shows a flow chart of a method for preventing loss of items provided by the first embodiment of the present invention. The method for preventing loss of items in the embodiment of the present invention includes a master device for preventing loss and a slave device for preventing loss. The slave device for preventing loss can be made into a Bluetooth Modules (such as Bluetooth modules made of Bluetooth Low Energy (BLE) chips (such as TI CC2541),) are attached to items that users do not want to lose, and communicate with the anti-lost master device and the anti-lost slave device The function realizes the anti-loss of items. Among them, BLE technology refers to a wireless technology with ultra-low power consumption, short distance, and low transmission rate. The details are as follows:

[0032] Step S11, acquiring the RSSI value currently received by the loss prevention master device.

[0033] Among them, the anti-lost main device is usually a mobile device...

Embodiment 2

[0079] Corresponding to the method for preventing loss of items provided in Embodiment 1, Figure 5 It shows a schematic structural diagram of the article anti-lost device provided by the second embodiment of the present invention. The article anti-lost device can be applied in the anti-lost master device. For the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0080] The article anti-lost device includes: an RSSI value acquisition unit 51 , a filter processing unit 52 , a dynamic RSSI value generation unit 53 , an RSSI value comparison unit 54 , and a continuous attenuation analysis unit 55 . in:

[0081] The RSSI value acquiring unit 51 is configured to acquire the RSSI value of the signal strength indicator currently received by the anti-lost master device.

[0082] Among them, the anti-lost main device is usually a mobile device carried by the user, such as a mobile phone, a wearable device, etc., and the anti-los...

Embodiment 3

[0119] Figure 6 is a schematic diagram of a terminal device provided by the third embodiment of the present invention. Such as Figure 6 As shown, the terminal device 6 of this embodiment includes: a processor 60 , a memory 61 , and a computer program 62 stored in the memory 61 and operable on the processor 60 . When the processor 60 executes the computer program 62, the steps in the above embodiments of the data communication method are implemented, for example figure 1 Steps S11 to S15 are shown. Alternatively, when the processor 60 executes the computer program 62, it realizes the functions of the modules / units in the above-mentioned device embodiments, for example Figure 5 Function of units 51 to 55 shown.

[0120] Exemplarily, the computer program 62 can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 61 and executed by the processor 60 to complete this invention. The one or more modules / units may be a series o...

Abstract

The invention is applicable to the technical field of communication, and provides an article loss prevention method, a loss prevention device and terminal equipment. The method comprises steps: the current RSSI (Received Signal Strength Indication) value of loss-prevention main equipment is acquired; the acquired RSSI value is filtered; according to the filtered RSSI value, a dynamic RSSI threshold is generated; the filtered RSSI value is compared with the dynamic RSSI threshold; and if the filtered RSSI value is smaller than the dynamic RSSI threshold, the RSSI value acquired in a preset timeperiod is subjected to continuous attenuation analysis, and alarming indication is given when the continuous attenuation analysis result meets an alarming condition. Through the above method, the accuracy of the given alarming indication can be improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method, a device and a terminal device for preventing loss of items. Background technique [0002] At present, the pace of people's life is getting faster and faster, and the fast pace of life is more likely to cause items to be lost. Such as the loss of wallets, mobile phones, U disks, handbags, etc. But no matter what article is lost, because the article itself has certain value, and the article itself may also preserve important information, therefore, the owner of the article often brings great trouble after the article is lost or stolen. For example, for salesmen in industries such as insurance, real estate, and lawyers, their mobile phones, USB flash drives, and handbags usually store a large amount of customer information. In addition, it is very likely that the customer corresponding to the customer information will be lost directly, which will bring...
