Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

The terms of relevance in the present invention are explained as follows:

radio Frequency Identification (RFID), which is one of automatic Identification technologies, performs contactless bidirectional data communication in a Radio Frequency manner, and reads and writes a recording medium (an electronic tag or a Radio Frequency card) in a Radio Frequency manner, thereby achieving the purposes of identifying a target and exchanging data.

The radio frequency identification technology realizes non-contact two-way communication by combining radio wave non-contact quick information exchange and storage technology and wireless communication with data access technology and then connecting a database system, thereby achieving the aim of identification. In the identification system, reading and writing and communication of the electronic tag are realized through electromagnetic waves. According to the communication distance, a near field and a far field can be divided, and for this reason, the data exchange method between the read/write device and the electronic tag is correspondingly divided into load modulation and backscatter modulation.

The electronic tag is also called as a radio frequency tag, a transponder and a data carrier; the reader is also called a reading device, a scanner, a reading head, a communicator, a reader/writer (depending on whether the electronic tag can wirelessly rewrite data). The electronic tag and the reader realize space (non-contact) coupling of radio frequency signals through a coupling element; and in the coupling channel, energy transfer and data exchange are realized according to a time sequence relation.

Radio Frequency Identification (RFID) is an abbreviation for Radio Frequency Identification. The principle is that non-contact data communication is carried out between the reader and the tag, so that the aim of identifying the target is fulfilled. The application of RFID is very wide, and typical applications include animal wafers, automobile wafer burglar alarms, access control, parking lot control, production line automation and material management.

A Mesh network, i.e., a wireless Mesh network, is a multi-hop (multi-hop) network, is developed from an ad hoc network, and is one of key technologies for solving the problem of the last mile. In the process of evolving to the next generation networks, wireless is an indispensable technology. The wireless mesh can be cooperatively communicated with other networks, and is a dynamic and continuously expandable network architecture, and any two devices can be wirelessly interconnected.

Referring to fig. 1, the embodiment provides a system based on RFID base station positioning, including an RFID base station, an RFID electronic tag disposed at an equipment end, and a data receiving end; the data receiving end is a mobile phone end application or a cloud; the equipment end is provided with an indicator light and a buzzer.

When equipment with an RFID electronic tag enters the action range of an RFID base station, the RFID base station judges whether the current equipment is registered in the current RFID base station or not according to data responded by the RFID electronic tag at the equipment end, and if the current equipment is not registered, new equipment is found at one end of the equipment through a buzzer or an indicator light; and if the current base station is registered, displaying that the equipment is accessed to the current base station at one end of the equipment.

When the equipment with the RFID electronic tag leaves the action range of the RFID base station, if the equipment is not registered in the base station, an indicator lamp at the equipment end is turned off to prompt that the equipment leaves the action range of the base station; if the equipment is registered in the base station, an indicator lamp of the equipment end is turned off, and meanwhile, a buzzer sounds to prompt that the equipment leaves the action range of the base station.

An RFID base station, comprising: the RFID reader-writer comprises an RFID reader-writer, a controller, an indicator light, a buzzer and a communication module.

The controller controls the RFID reader-writer to send a data request, so that the RFID electronic tags in the action range respond;

when equipment with an RFID electronic tag enters the action range of an RFID base station, the RFID base station judges whether the current equipment is registered in the current RFID base station or not according to the data responded by the RFID electronic tag at the equipment end, and if the current equipment is not registered, the new equipment is prompted to be found at one end of the base station and automatically registered; if the equipment is registered, the equipment is prompted to be accessed to the current base station at one end of the base station.

When the equipment with the RFID electronic tag leaves the action range of the RFID base station, if the equipment is not registered in the base station, one end of the base station newly finds that the equipment state disappears; if the equipment is registered in the base station, the equipment state at one end of the base station is displayed as off-line, and meanwhile, the buzzer sounds to prompt the equipment to leave the action range of the base station.

The communication module reports the current state of the RFID base station to a mobile phone end application or cloud in real time or non-real time, wherein the current state comprises the number of the RFID base station, the position of the RFID base station, equipment registered on the base station, the signal intensity of the equipment and the base station, and unregistered equipment in the action range of the base station. The communication module can adopt short-range wireless communication technology, such as Zig-Bee, Bluetooth (Bluetooth), wireless broadband (Wi-Fi), ultra-wideband (UWB) and Near Field Communication (NFC), and also can adopt long-range wireless communication technology, such as GPRS, CDMA, LTE, NBIOT, CAT1 and the like.

And if the current space has a plurality of RFID base stations, the base stations form a mesh network.

When equipment registered on the RFID base station A enters the action range of the RFID base station B and the signal intensity of the base station B is greater than that of the base station A, registering the equipment on the base station B and removing the registration relation on the base station A; and simultaneously, the communication module of the base station B reports the new registration relation of the equipment to a mobile phone end application or cloud.

And the mobile phone end application or the cloud draws a topological graph of the base station and the equipment according to the reported data of the RFID base station, including the number of the RFID base station, the position of the RFID base station, the equipment registered on the base station, the signal strength of the equipment and the base station, the unregistered equipment in the action range of the base station, and then draws an equipment distribution diagram by combining the house type structure of the current space.
