Embodiment Construction

[0027] The specific implementation manners provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, when the targets are respectively located in the A1-A16 area, each set of data composed of the output voltages of the four detectors is different, that is, each set of data collected by the system is different. The position of the target can be calculated by judging the different data collected by the system.

[0029] Such as figure 2 As shown, to achieve target positioning, the following two steps need to be completed:

[0030] (1) Establish a kNN classification model. Including steps S1, S2, S3.

[0031] S1: Divide the monitored area into several areas and number them, and deploy one-dimensional capacitive proximity detectors. figure 1 It is a deployment diagram of using four one-dimensional capacitive detectors for positioning in the present invention. Four one-dimensional cap...

Abstract

The invention discloses an indoor positioning method based on capacitance proximity detection, and belongs to the technical field of positioning. The indoor positioning method comprises the followingsteps of dividing a monitored area into a plurality of areas, numbering, and arranging a one-dimensional capacitance proximity detector; collecting data of a target in each numbered area; training allthe data, and establishing a K-nearest neighbor classifying model; when the target enters the monitored area again, utilizing an established model to obtain a position number of the target, so as toachieve the positioning. The indoor positioning method has the advantages that the convenience in use is realized, the power consumption is low, the anti-electromagnetic interference ability is realized, the cost is low, and the like; the defects of the existing indoor positioning technique can be overcome; by adopting a machine learning method, the positioning effect is good.

Description

technical field [0001] The invention belongs to the technical field of indoor positioning, and relates to an indoor positioning method based on capacitive proximity detection. Background technique [0002] The population structure of China's society is aging quietly. In order to meet the needs of the elderly in the new situation, a new type of apartment for the elderly was born. In order to achieve safer care for the elderly in the elderly apartment, it is necessary to introduce the concept of intelligence into the design of the elderly apartment. Among them, the indoor positioning technology can complete the monitoring of accidents of the elderly, such as falls and faints. [0003] The commonly used indoor positioning methods at this stage can be divided into those that require auxiliary equipment and those that do not. Positioning technologies such as Wi-Fi, Zigbee, RFID, Bluetooth, and ultra-wideband need to carry smart phones, electronic tags, or client terminals with ...
