Embodiment Construction

[0074] The specific implementation manner and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0075] From Figure 1-3 It can be seen that a cattle indoor positioning system based on UWB communication technology includes a positioning processor, and U UWB receiving devices are connected to the positioning processor, and U UWB receiving devices are used to be installed on the top of the cow pen. The U UWB receiving devices are all used to receive the position data sent by the G UWB transmitting devices, so as to obtain the measurement data. The G described UWB transmitting devices are respectively worn on the G cows, and the positioning processor is provided with The data optimization module is used to obtain the motion state of the cattle according to the measurement data and the jump filter, and select the extended Kalman filter algorithm or the median filter algorithm to optimize the measure...

Abstract

The present invention discloses a UWB communications technology-based cow indoor positioning system and a heuristic jumping filter positioning method. The positioning system comprises a positioning processor. U UWB receiving apparatuses are connected to the positioning processor. The U UWB receiving apparatuses are installed on the top of a cow enclosure, and the U UWB receiving apparatuses are all used for receiving position data sent by G UWB transmitting apparatuses, so as to obtain measurement data. The G UWB transmitting apparatuses are separately worn on G cows. A data optimization module is disposed inside the positioning processor, and is used for obtaining a motion state of the cows according to the measurement data and a jumping filter, and performing optimization processing on the measurement data by selecting an extended Kalman filter algorithm or a median filter algorithm according to the motion state. Beneficial effects are that, the positioning system is less dependent of environment and is high in efficiency, and positioning precision and accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of carrier-free communication indoor positioning, in particular to an indoor positioning system for cattle based on UWB communication technology and a heuristic jump filter positioning method. Background technique [0002] In the past few years, a variety of indoor positioning systems for livestock buildings have been launched on the market. If sufficient positioning accuracy and sampling rate can be achieved, these systems would be interesting tools in automated animal industry monitoring. For cattle during the feeding process, the analysis of cattle positioning system data shows that the measurement data can be used to measure feeding time; it is also possible to monitor cattle hoof lesions by obtaining and locating the cattle’s walking distance and walking time; and for cattle The movement speed and frequency of the movement can monitor the physiological period of the cattle and whether they are in estru...
