Roll-based pattern recognition machine bidirectional path detection method

The present invention relates to a pattern recognition based method for detecting Pool bidirectional machine, the method comprising: (1) shows the state of each infrared tubes with four variables; (2) according to step (1) of the four variables IR value and the current state of the tube, is determined through the Pool-forward mode or a machine model; (3) according to step (2) is determined and the corresponding model variable values ​​comprehensive judgment, whether by someone; (4) repeating step (1) - (3). The present invention is by using a single-chip state infrared tube real-time detection and processing according to the collected data, the determination of the personnel access, this method saves CPU resources, higher real-time detection, speed by personnel did not special needs, adaptability, and no need to increase the number of infrared tubes, or when someone brings something is waved by a big margin will not cause erroneous judgment, but also has anti-tail function.
