This invention discloses a land surveying and measurement device and its usage method, relating to the field of land surveying technology. It includes a surveying instrument and a tripod assembly and an adjustable toe assembly that provide support for the instrument. The adjustable toe assembly can be switched to adapt to the setup needs of hard and soft ground. The adjustable toe assembly includes a foot spike unit, a rubber foot unit, and a quick-lock unit. This invention, by setting up an adjustable toe assembly, allows for purely foot-based operation: stepping on a second pedal to lower and lock the instrument, and stepping on a linkage deflection component to unlock and reset it. Combined with the fact that the hands only need to lift and lower the support frame, it completely liberates the surveyor's waist. In long-distance operations with frequent terrain changes, it significantly reduces physical exertion. Furthermore, through the linkage structure of the "pedal + quick-lock unit," the lowering and locking or unlocking and resetting of the rubber foot covers can be completed simultaneously within seconds, greatly shortening the instrument setup time.

This invention discloses a distribution network scheduling optimization method based on an energy storage system, belonging to the field of power system optimization and scheduling. With the goal of minimizing photovoltaic curtailment, load shedding, and the operating costs of mobile energy storage (MESS), a traffic-distribution network coupled optimization model is constructed. Based on the traffic uncertainty at each time period on the road, a constraint relationship is established between path state variables and driving state variables to simulate the traffic congestion delay of the MESS, while ensuring sufficient charging and discharging time for the MESS at each node. The coupling between the transportation network and the distribution network is achieved through the path state variables, driving state variables, and output power of the MESS. Traffic uncertainty is transformed into an opportunity constraint on congestion delay. By simulating the congestion delay of the MESS through path state variables and driving state variables, the driving behavior and power scheduling of the MESS are optimized, thereby improving the distribution network's capacity to support photovoltaic power generation and residential loads.

This disclosure provides a method, device, electronic equipment, and storage medium for monitoring and diagnosing power distribution equipment, relating to the field of power distribution equipment monitoring technology. It generates dynamic state benchmarks corresponding to short, medium, and long periods through multi-timescale hierarchical processing. The current state observation vector is then compared hierarchically with each level of benchmark to generate hierarchical state residuals. Multiple candidate fault hypotheses are generated based on these hierarchical state residuals, and their validity, exclusion, and correlation are triple-checked using monitoring correlation information and multimodal operating data. Finally, the target fault hypothesis with the highest matching degree to the current operating deviation state is determined based on the check results. Therefore, this method can solve the problems in existing technologies where insufficient state correlation analysis during edge-side monitoring and the difficulty in effectively analyzing the complex correlation between abnormal behavior and equipment objects, operating conditions, and historical states lead to inaccurate anomaly localization and a lack of clear diagnostic direction.
