2results about How to "Reduce detection power consumption" patented technology

The application provides a photon detection method, device and laser radar for a full solid-state laser radar, the method comprising: calibrating a SPAD array, determining SPAD units included in a photosensitive pixel corresponding to each light spot or light strip emitted in a laser, and recording the SPAD units as an initial opening region; opening the SPAD units of the initial opening region to detect a target; obtaining histogram data output by the opened SPAD units; adaptively adjusting the position of the SPAD units opened next time according to the histogram data, when the signal-to-noise ratio in the histogram data of the SPAD units opened next time meets a set value, the SPAD units opened next time are required SPAD units; and calculating distance information of the target according to the histogram data output by the required SPAD units. Through region calibration of the SPAD array, the opening position of the SPAD units is adaptively adjusted based on the signal-to-noise ratio for photon reception at each exposure, which ensures the detection effect while effectively reducing the detection power consumption and data volume.

The invention provides a communication method, communication equipment and a communication system, and relates to the technical field of communication. The method comprises the following steps that: network equipment sends a specific first sequence to terminal equipment on a first time-frequency resource, so that whether first SPS scheduling is activated or not can be indicated through the first sequence; therefore, the terminal equipment does not need to acquire the indication information of SPS scheduling activation based on downlink control information DCI blind detection, and the detection power consumption of the terminal equipment can be saved.
