Embodiment Construction

[0024] 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.

[0025] figure 1 The conceptual diagrams illustrate specific examples of remote object location methods and systems. In an operating environment [10] (not part of this invention), such as a patient, or in a confined environment 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 p...

Abstract

The invention provides a method and a system for remote locating on basis of at least four magnetic field sensor array planes, wherein the system comprises a location object, magnetic sensor arrays, magnetic field spatial analytical equipment and background magnetic field compensation sensors, and the location object needs to have a magnetic field, such as a capsule or a probe which contains a permanent magnet; and the magnetic sensor arrays comprise four or more than four non-fixed magnetic field sensor array planes, a Hall sensor and a magnetorsistive sensor. According to the method and the system for remote locating on the basis of at least four magnetic field sensor array planes, the target area is located among the four or more than four magnetic field sensor array planes, the strongest field intensity points of all the planes are found out, and through utilizing the solid geometry knowledge and combining with the magnetic field compensation information, the object can be remotely located.

Description

technical field [0001] The invention relates to a magnetic field positioning method, in particular to a plane remote positioning method and system based on an array of no less than four magnetic field sensors. 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...
