Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] Aiming at the power system inspection process, the technical solution of the present invention proposes an indoor hybrid positioning method for substation robots based on WIFI and RFID. The WIFI positioning technology not only has good accuracy and scalability, but also can realize complex large-scale positioning , to facilitate networking. The target location is obtained by comparing the WIFI signal feature fingerprint information required for positioning. The basic principle of RFID positioning is to read the characteristic information of the target RFID tag (such as ID, received signal strength, etc.) through a set of fixed readers, and determine the location of the robot by receiving the signal strength of the robot's tag.

[0039] The technical solution of the present invention is an indoor hybrid positioning method of a substation robot based on WIFI and ...

Abstract

The invention discloses a transformer substation robot indoor hybrid positioning method based on WIFI and RFID, and belongs to the field of control. A transformer substation indoor hybrid positioningdevice composed of a main controller, a WIFI receiver, WIFI hotspots, RFID electronic tags and an RFID reader-writer is constructed in a transformer substation. The main controller and the WIFI receiver receive data sent by each WIFI hotspot in real time; the RFID reader-writer receives signals sent by the RFID electronic tags in real time and transmits the signals to the main controller; a fingerprint identification algorithm is adopted, WIFI and RIFD positioning is carried out, the received signal intensity is compared with a fingerprint database, and the real-time position of the mobile robot in the transformer substation is given. When WIFI signals are weak, the RFID positioning technology is adopted, and when RFID label positioning is unstable, the WIFI positioning technology is adopted. The instability of receiving a single signal is prevented, and the indoor positioning precision of the transformer substation robot is improved.

Description

technical field [0001] The invention belongs to the field of control, in particular to an indoor mixed positioning method for a substation robot based on WIFI and RFID. Background technique [0002] In modern society, electricity is a very important energy source. In recent years, with the prosperity and development of our country, the country has invested heavily in the power system, which includes infrastructure such as hydroelectric power stations, coal-fired power plants, nuclear power stations, substations, switching stations, and street substations. There are many electrical equipment and power automation products to ensure the stable operation of the power system. [0003] The stability of the power system is related to all walks of life in our country, and plays a very important role in the energy stability of our industry, commerce, real estate and other industries. Among them, the key infrastructure for controlling power transmission and distribution is the subst...
