DETAILED DESCRIPTION

In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

Embodiment 1

FIG1 shows the implementation process of the method for anti-theft positioning of items provided in the first embodiment of the present invention, which is described in detail as follows:

Step S101: sending coded information corresponding to the target object to a reading device via an electronic tag set on the target object.

In one embodiment, the electronic tag may be an RFID-SIM card. The obtaining of the current position of the target object is specifically: using a network signal generated by traffic in the RFID-SIM card as a sending medium and a receiving medium to obtain the current position of the target object.

The RFID system consists of two major parts, one is the electronic tag, and the other is the reading device. The electronic tag includes a chip, an antenna and a carrier. In this embodiment, the electronic tag is realized by an RFID-SIM card. When the RFID-SIM card enters the working area of the transmitting antenna, an induced current is generated. The RFID-SIM card obtains energy and starts to work (electromagnetic induction). The card will immediately send its own code (UD, ubiquitous ID) and other information through the antenna built in the RFID-SIM card to the reading device that matches the RFID-SIM card. The antenna of the reading device receives the carrier signal sent back from the tag, and the antenna adjusts and transmits it to the reader in the reading device. The reader demodulates and decodes the received signal and then sends it to the background AP (Wireless Access Point) for related processing. The AP determines the legitimacy of the electronic tag based on logical operations and turns out the instruction signal to control the next action.

The reading range of the reading device is controlled within M (for example, M = 5) meters. When the electronic tag attached to the target item is within the reading range, the electronic tag is in the reading state, and the background AP tells the reading device to emit the first type of sound; if the electronic tag is not within the reading range, the reading device cannot read the electronic tag, and the background AP will tell the reading device to emit the second type of sound. Users can judge whether the item is stolen based on the different sounds.

RFID-SIM card works and communicates by embedding RF (Radio Frequency Identification) chip into standard SIM (Subscriber Identification Module) card, and can use the CPU on the SIM card to perform calculations. RFID-SIM card is a product that penetrates the mobile phone field with dual-interface smart card (RFID card and SIM card) technology, and is a new mobile phone SIM card. RFID-SIM card has the same mobile communication function as ordinary SIM card, and can also communicate with the card reader in short distance through the antenna attached to it, so it can be expanded to non-typical fields, especially mobile phone on-site payment and identity authentication functions.

Step S102: decoding the coded information by the reading device, identifying the decoded information obtained after the decoding, and determining the positional relationship between the electronic tag and the reading device according to the identification result of the decoded information.

Among them, the decoding information obtained after the decoding process is identified, and the positional relationship between the electronic tag and the reading device is determined according to the identification result of the decoding information. Specifically, the legitimacy of the decoding information is identified through logical operation, and then the positional relationship between the electronic tag and the reading device is determined according to the legitimacy of the decoding information.

Step S103, when the distance between the electronic tag and the reading device exceeds a preset range, a positioning device disposed on the target object is activated to obtain the current position of the target object.

The step S103 of acquiring the current position of the target object may specifically include: using the network signal generated by the traffic in the RFID-SIM card as the sending medium and the receiving medium to acquire the current position of the target object.

The GPS system (Global Positioning System) consists of three parts: the GPS satellite constellation in space, the ground monitoring system and the user equipment GPS signal receiver. The GPS signal receiver can capture the signals of the satellites to be measured selected at a certain satellite altitude cutoff angle and track the movement of these satellites. It transforms, amplifies and processes the received GPS signals to measure the propagation time from the GPS signal to the satellite to the receiver antenna, interprets the navigation message sent by the GPS satellite, and calculates the three-dimensional position and even the three-dimensional speed and time of the measuring station in real time.

In this embodiment, the 3G, 4G or even 5G signal generated by the traffic in the RFID-SIM card can be used as the sending medium and the receiving medium. First, the RFID-SIM card is connected to the system server, and the base station address of the signal tower is used to locate the approximate range. Then, the signal received by the server (including the ASCII code of longitude and latitude) is input into the electronic map of the network server through the data connection to determine the precise location. The whole process can be controlled within 30 seconds, and the error is controlled within 10 meters. Users can locate items based on this part and finally determine the exact location of the items.

In addition, in step S103, when the distance between the electronic tag and the reading device exceeds a preset range, the method may further include: generating an alarm prompt through the reading device to remind the user that the item exceeds the preset range and may be stolen, lost, etc.

Step S104: sending the current location of the target object to the corresponding smart terminal for display.

By sending the current location of the target object to the corresponding intelligent terminal, the owner of the target object can obtain the real location of the target object for easy searching.

RFID radio frequency identification technology is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require human intervention. It can work in various harsh environments and can identify high-speed moving objects. RFID technology can identify multiple tags at the same time, and the operation is quick and convenient. GPS technology is also known as the global positioning system. Its overall deployment can achieve all-weather, high-precision and global coverage. GPS technology combined with modern communication technology has expanded its application breadth and depth, greatly improved relative positioning accuracy, and can achieve centimeter-level accuracy in a small range. Cloud service technology allows users to store and read data through the Internet, and can use cloud services as needed and obtain the location information of items at any time. RFID radio frequency identification technology, GPS and cloud service technology are effectively combined. The former realizes item theft prevention, GPS realizes item positioning, and uses the functions of cloud servers to transmit data, which guarantees the safety of customers' property to the greatest extent.

The above-mentioned object anti-theft positioning method sends the coded information corresponding to the target object to the reading device through the electronic tag set on the target object, the reading device decodes the coded information and identifies the decoded information, and judges the position relationship between the electronic tag and the reading device based on the recognition result of the decoded information. When the distance between the electronic tag and the reading device exceeds a preset range, an alarm is generated and a positioning device set on the target object is started to obtain the current position of the target object, and the current position of the target object is sent to the corresponding intelligent terminal for display, so that the user can be reminded when the object exceeds the preset range and the current position of the object can be located, which is convenient for positioning and searching.

It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

First, the RFID-SIM card is connected to the system server, and the base station address of the signal tower is used to locate the approximate range. Then, the signal received by the server (including the ASCII code of longitude and latitude) is input into the electronic map of the network server through the data connection to determine the precise location. The whole process can be controlled within 30 seconds, and the error is controlled within 10 meters. Users can locate items based on this part and finally determine the exact location of the items.
