The invention belongs to the technical field of embedded computers, and discloses a design method for missing alarm prevention for switch
machine gap monitoring. The method is realized through an industrial
computer processing module, a data receiving and storing module and a
machine learning identification module. The industrial
computer processing module uploads the collected conventional data packet, video data and gap data packet of an industrial computer to an NVR
server, and simultaneously updates the display information of an upper computer. The data receiving and storing module receives the data uploaded by the industrial computer, displays the data on the upper computer, and stores the data in the NVR
server. The
machine learning identification module establishes an image classification
database, introduces a
convolutional neural network, and establishes a classifying and sampling
learning unit for the image classification
database. Finally, a video frame is output through Fast R-CNN. The video frame is processed. An alarm type is output. Finally, the detected alarm type is compared with the alarm type of the industrial computer to acquire alarm information. According to the invention, missing alarm and
false alarm of a switch machine can be effectively prevented, and the reliability of gap
video monitoring of the switch machine is improved.
