Abstract: Disclosed are an object detection device and a control method. A method for controlling an object detection device comprises the steps of: receiving one image; dividing the received image into a predetermined number of local areas on the basis of the size of a convolutional layer of a convolution neural network (CNN); identifying small objects at the same time by inputting a number of the divided local areas corresponding to the number of CNN channels to each of a plurality of CNN channels; sequentially repeating the identifying of the small objects for each of the remaining divided local areas; selecting MM mode or MB mode; setting an object detection target area corresponding to the number of CNN channels on the basis of the selected mode; and detecting the small objects at the same time by inputting each set object detection target area to each of the plurality of CNN channels.

Abstract: Disclosed is a system and method for querying and recovering circuit group state in a switching system. A self station searches processors including circuit groups which are allocated to a certain route, and requests circuit group state from the searched processors successively. The processors receiving the request identify whether or not a corresponding circuit is allocated to the certain route by reviewing all circuits included in the processors. In addition, the processor groups circuits which are successively allocated among the circuits allocated to the certain route, and queries state of the circuits by generating one CQM per group. When the query process is completed by the processors, the self station reports results of the circuit group state query to an operator. Therefore, the operator can query the states of circuit groups as a route unit in the self station.
