A Target Tracking and Positioning System on Conveyor Belt

Abstract

The invention relates to the technical field of wireless communications, and provides a target tracking-positioning system on a conveying belt. The target tracking-positioning system comprises an ultra-wideband positioning module, two wireless modules, an upper computer and a server, wherein the ultra-wideband positioning module comprises two an anchor modules and one target module; the two anchor modules can be used for measuring distances between the anchor modules and the target module in real time, and transmitting distance data to the target module; the target module is used for transmitting the received distance data to the upper computer through the wireless modules; the upper computer is used for receiving the distance data through the wireless modules, displaying the measured distances, calculating coordinates of a target object according to an algorithm, simultaneously displaying the real-time position coordinates and moving track of the target object, and transmitting coordinate information to the server; the server is used for storing the coordinate information of the target object. A carrier-free communication technology ultra-wideband technology is applied, so that the target tracking-positioning system has the advantages of high interference resistance, high transmission rate, high system capacity, low transmission power, accurate positioning, lower power consumption, safety, reliability, easiness in operation and easiness in installation.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a target tracking and positioning system on a conveyor belt. Background technique [0002] There are already many object positioning systems using different principles in the market, including using electromagnetic wave signals, laser signals, infrared signals, sound waves, and so on. On the one hand, the positioning system of the electromagnetic wave signal has the advantage of a long working distance, but because the electromagnetic wave propagates at the speed of light in the air, the method of measuring the distance in a timing manner has a large error in the ranging range of tens of meters, even if After using advanced signal processing methods such as Kalman filter and extended Kalman filter, it is difficult to make the ranging accuracy reach the meter level. At the same time, the use of these technologies will make the system structure complex and the cost w...

On the one hand, the positioning system of the electromagnetic wave signal has the advantage of a long working distance, but because the electromagnetic wave propagates at the speed of light in the air, the method of measuring the distance in a timing manner has a large error in the ranging range of tens of meters, even if After using advanced signal processing methods such as Kalman filter and extended Kalman filter, it is difficult to make the ranging accuracy reach the meter level. At the same time, the use of these technologies will make the system structure complex and the cost will increase, without large-scale use; using laser or Infrared signal positioning system, due to the good directionality of infrared rays, this kind of system can only locate objects in a certain direction, and because of the poor penetration ability of infrared rays, the infrared emission and the measured object The system will fail when there is an object blocking it; the sound wave signal is easily interfered by the reflection of environmental debris, and the water, ice, and soil block will fail

On the other hand, the existing wired acquisition system has the problems of high maintenance cost, cumbersome maintenance work and certain potential safety hazards
