Method and system for positioning dairy cow individuals

Abstract

The invention relates to a method and a system for positioning dairy cow individuals. The recognition accuracy of the dairy cow individuals is improved, in particular to the recognition accuracy of multiple pedometers within a smaller range. The method comprises the following steps of setting an excitation range by controlling low-frequency field intensity, and continuously sending low-frequency activating signals at a scheduled period within the excitation range; receiving field intensity reference data from at least one pedometer within the excitation range by high-frequency transceiving; recording the current field intensity reference data after low-frequency activating information within the excitation range is received by the pedometers, and activating the high-frequency transceiving of the pedometers so as to send the field intensity reference data; and sending the field intensity reference data and the excitation range to an upper computer server.

Description

technical field [0001] The embodiments of the present invention relate to information positioning technology, in particular to a method and system for individual dairy cow positioning. Background technique [0002] In the current dairy farming industry, the intelligent breeding of individual cattle is still relatively weak. For the identification of individual cattle, only the identification of fixed numbers can be achieved, but the positioning of individual cattle cannot be achieved (such as: sports field positioning, fence position positioning), thereby affecting the parameter collection of cattle and the correspondence of related sign data. As a result, information such as physiological characteristic analysis data and milk production cannot be correctly associated and processed in a timely manner, thereby affecting the continuous monitoring of individual cattle, as well as the analysis and processing of physiological characteristics.

Problems solved by technology

However, the positioning error of this system in the prior art is about 1 meter, and the accuracy is not enough. When there are many cows within the error range, it will not be able to effectively distinguish; the communication range between the reference node and the positioning node is preset and cannot be adjusted. Relatively single; the power consumption between the reference node and the positioning node is relatively large, resulting in a short service life and increased costs; in addition, most products on the market use a single frequency band design, the main problem of the single frequency band design: if only low frequency methods are used, Since the effective distance of low-frequency reading is usually less than 1 meter, the pedometer cannot achieve long-distance communication, and when there are multiple sensors within a small distance range, it is difficult to effectively distinguish; if only the ultra-high frequency method is used, However, due to the instability of the UHF electric field distribution, the reading accuracy is not high
