Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] figure 1 It is a flow chart of an early warning method in the present invention; see figure 1 As shown, the method includes the following steps:

[0043] Step 101, after power on, detect whether there is a signal of a specific frequency around. If yes, go to step 102; otherwise, go to step 103.

[0044] In step 101, after the early warning device is powered on, it judges whether it is a primary early warning device or a secondary early warning device by detecting whether there is a signal of a specific frequency around.

[0045] Step 102: Send a network access connection request to the main early warning device transmitting the specific signal, receive a returned network connection connection response, and join the early warning net...

Abstract

The invention discloses a pre-warning method and a pre-warning device. The method includes the steps that after electrification, whether a signal at a specific frequency exists around is detected; if yes, the pre-warning device serves as a secondary pre-warning device to send an internet access request to a primary pre-warning device emitting the specific signal, receives an internet access response which is fed back, and enters a pre-warning network built by the primary pre-warning device; if no, the pre-warning device serves as the primary pre-warning device to emit the signal at the specific frequency, receives internet access requests sent by other pre-warning devices serving as secondary pre-warning devices, feeds back a corresponding internet access response and accepts other pre-warning devices to enter the pre-warning network built by the primary pre-warning device; an alarm is given when the pre-warning device quits the pre-warning network. According to the technical scheme, the defect that salve devices cannot continue to be used when a master device of an existing Bluetooth pre-warning device is lost can be overcome.

Description

technical field [0001] The invention relates to the technical field of early warning device manufacture, in particular to an early warning method and an early warning device. Background technique [0002] In life, the valuables included in the carry-on are easy to be stolen, especially in crowded public places, causing unnecessary property losses to people. Most of the early warning devices currently on the market are based on Bluetooth technology and are realized by setting a safe distance. There are following disadvantages in this early warning device: [0003] First of all, the working frequency of Bluetooth technology is high, and when it is blocked by obstacles, the interference is relatively large; [0004] Secondly, the early warning devices currently on the market focus more on reminding or searching after the item exceeds a certain range (a dozen or tens of meters). The function fails; [0005] Third, although its detection distance can be from 0 to how many met...
