The invention provides a positive and negative current detection circuit for an H bridge, the positive and negative current detection circuit for the H bridge comprises a voltage boosting unit, a voltage following unit, a voltage selection unit and a current conversion unit, the voltage boosting unit amplifies a first terminal voltage and a second terminal voltage of a to-be-detected switch tube; isolation is carried out through a voltage following unit, a target detection voltage to be detected currently is determined through a voltage selection unit, finally, the target detection voltage is input to a first end of a load switch tube through a current conversion unit to generate a detection current, and a controlled end of the load switch tube is connected with a controlled end of a to-be-detected switch tube. And the working current of the to-be-detected switch tube can be calculated through conversion of the detection current.

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.

The invention belongs to the technical field of intelligent detection, and discloses a temporary grounding wire state detection method and device, and the method comprises the steps: determining a destination position of a temporary grounding wire and a target air pressure value according to an operation order, and collecting the real-time position information of the temporary grounding wire at a small frequency when the temporary grounding wire is monitored to leave a warehouse, thereby achieving the state detection of the temporary grounding wire. When the spacing distance between the real-time position information and the destination position is smaller than a specified threshold value, the real-time air pressure value of the temporary grounding wire is obtained at a large frequency and compared with a target air pressure value, if the real-time air pressure value is matched with the target air pressure value, it is judged that the temporary grounding wire reaches the destination position, and monitoring of the hooking state of the temporary grounding wire is started. Therefore, the detection power consumption of the hitching state of the grounding wire can be reduced.
