The invention provides an automatic simulated dummy projectile launching system. The problems that in the conventional simulation actual combat training process, the blast effect of blasting ammunition in the close combat is difficultly simulated in a vivid manner, and the death cannot be avoided are solved, and the problem that the non-gunpowder means is adopted to motivate a fuse so that the simulated dummy projectile is launched is solved; according to the technical scheme, the automatic simulated dummy projectile launching system comprises a canister launcher, a canister launcher control device and the simulated dummy projectile used for being loaded in the canister launcher; the simulated dummy projectile comprises a bomb body shell, a bomb core and a fuse structure at the bottom of a projectile body; the side wall of a canister launcher air cylinder is provided with an air guide hole used for communicating an air cylinder inner cavity with a canister launcher inner cavity, the lower portion of the air cylinder is connected with a high-pressure air storage tank through an air guide pipe and a normally-closed electromagnetic valve, through automatic identification of a target, cooperative control over launching of the percussion fuse is achieved, the projectile body is launched, exploding is simulated, in the launching process, the dangerous hidden dangers brought by gunpowder launching are completely avoided, operation is easy, and the system is safe, reliable, simple in structure and suitable for civil production manufacturing.

A distribution transformer gear recognition algorithm, the algorithm uses the distribution transformer topological relationship connected to the same 10kV line to determine the predecessor and successor relationship between adjacent distribution transformers; analyze the different gear voltages of adjacent distribution transformers Difference, if the voltage drop generated by the line impedance is regarded as noise, the voltage of the adjacent station area is not in the same gear, which will cause a different voltage difference, and then determine the gear relationship of the adjacent distribution transformer; through the adjacent station area Comparing the voltages of the two stations, and completing the analysis of the voltage levels of all stations. The algorithm of the present invention does not require the operation and maintenance personnel of the station area to check the actual gear position of the distribution transformer, but uses the existing operating data of the distribution transformer to realize online calculation of the gear position of the distribution transformer, thereby providing the power supply reliability of the station area. The algorithm of the invention can accurately determine the actual gear position of the distribution transformer, and is suitable for large-scale application and popularization.
