Abstract: A detection control method and an apparatus are described that are used for target detection, and may be applied to the fields such as intelligent driving, intelligent transportation, surveying and mapping, and intelligent manufacturing. A control apparatus controls a laser emitting unit and a laser receiving unit to perform two phases of laser detection. A first phase of laser detection is used to determine a time location, and a second phase of laser detection is used for target detection in a time window including a first time location. In one aspect, in the second phase of detection process, the control apparatus controls a laser detection unit to receive an echo signal in a first time window. A time for receiving the echo signal is shortened, thus permitting an amount of data in the detection process to be reduced.

Abstract: The invention relaxes to a replacement scheduling method and system for ultra-low loss optical fibers in a backbone network, which are designed to improve spectrum, utilization efficiency. The method includes: S1: calculating a gam respectively after each optical fiber link is replaced, that is, calculating a product of multiplying a quantity of frequency slots (FSs) reduced after each optical fiber link is replaced by a remaining time for finishing replacing all the remaining optical fiber links; S2: selecting an optical fiber link having the highest gain after the optical fiber link is replaced to perform replacement; and repeating S1 and S2 until all the optical fiber links that need to be replaced have been replaced. In the present invention, a replacement order of optical fibers is arranged most appropriately, so as to save as many as spectrum resources for operators for use by additional services. (FIG.
