Embodiment Construction

[0026] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] figure 1 The conceptual diagrams illustrate specific examples of remote object location methods and systems. In operating environments [10] (not part of this invention), like patients, or in confined environments such as machinery, fluid handling and hydraulic systems, at least one sensor array [12] is placed within each other in a specific configuration that will be further explained here. The sensor array [12] comprises one or more individual sensor units [14] and is evenly distributed on the sensor plane corresponding to the target area [16] in the operating environment [10]. The sensor array [12] will be connected to a suitable computer or data processi...

Abstract

The invention provides remote target locating method and system based on a dual-magnetic field sensor array plane. The system comprises an object required to be located, a magnetic sensor array, a magnetic field space analysis device and a background magnetic field compensation sensor. The invention provides the remote target locating method and system based on the dual-magnetic field sensor array plane; a target area is between two magnetic field sensor array planes; a point with the strongest field intensity in the two planes is found out, and then the remote target can be located by utilizing physical and mathematical knowledge combined with magnetic field compensation information. The method is not only suitable for an open environment, but also is suitable for a closed environment, such as a human digestive system, a liquid processing pipeline or some mechanical systems. According to the method, the defects of traditional remote locating are abandoned, and the method has the advantages that the location is accurate, the cost is low, the efficiency is high and the calculation is simple.

Description

technical field [0001] The invention relates to a magnetic field positioning method, in particular to a plane remote target positioning method and system based on a dual magnetic field sensor array. Background technique [0002] Survey wireless medical capsules are well known in the medical world. The survey capsule sends data back to a receiving and recording device placed outside the body. The patient swallows the capsule and it travels down the digestive tract, collecting and transmitting data along the way to a receiving and recording device. Typically, after one to two days, the disposable capsules are excreted with feces and data such as body temperature, pH, blood pressure, and transit time are recorded for analysis and / or storage for transmission. The industry generally agrees that wireless medical capsules equipped with cameras can be used to capture images, while capsules with drug reservoirs can release various doses of drugs to various regions of the digestive ...
