Facility location management method based on multi-scale fusion positioning

Abstract

The invention provides a facility location management method based on multi-scale fusion positioning. The method comprises the steps that 1 an electronic identifier is arranged on a facility, and a database is established on a server according to the relevant information of the facility and the electronic identifier; 2 the mobile terminal requests the relevant information of the to-be-checked facility to the server, and the server returns corresponding relevant information; 3 according to the returned relevant information, the location area where the to-be-checked facility is located is acquired through a positioning system; 4 the electronic identifier of the to-be-checked facility is searched through an electronic identifier reader in the location area; and 5 when the electronic identifier of the to-be-checked facility is read, the coordinate of the mobile terminal is taken as the coordinate of the to-be-checked facility. According to the invention, a device can be quickly identifiedand accurately positioned; and the positioning accuracy reaches the decimeter level, which is much higher than the positioning accuracy of 2 to 3m of a common GPS system.

Description

technical field [0001] The present invention relates to the technical fields of wireless positioning technology and the Internet of Things, and in particular, relates to a facility location management method based on multi-scale fusion positioning. Background technique [0002] In order to save space, public equipment such as heat pipelines, power pipelines, and oil pipelines are generally buried below the surface; the normal operation of these underground public facilities is of great significance to people's lives and social production. However, in the initial stage of construction, the construction of these underground equipment often lacks reasonable planning and scheduling, so that its data are not properly managed and preserved. With the increase in the number of underground equipment, the lack of reasonable underground equipment management methods has become a weak link in underground equipment construction. When underground equipment fails, due to the lack of data, ...

Problems solved by technology

However, the 125kHz RFID system is susceptible to power frequency interference of the equipment power supply, and there are problems such as large antenna size, antenna transmission efficiency is easily reduced by the influence of surrounding equipment metal materials, and the reading distance is short in low-loss media.

The existing 125kHz RFID with the best performance must be installed more than 10cm away from the equipment, which still cannot achieve accurate positioning of underground equipment
