This invention belongs to the technical field of aviation transponder pulse overlap signal separation methods, specifically relating to a separation method applicable to Mode A / C aviation transponder pulse collision conditions. By analyzing the differential characteristics of the Mode A / C aviation transponder signal waveform in the time and energy domains, the pulse collision signal is effectively split. Based on the waveform definition characteristics of the Mode A / C aviation transponder signal, the pulse frame is accurately recovered from the separated signal, ultimately completing the separation process of the Mode A / C collision pulse signal. This invention requires only a single-channel receiver to achieve signal separation, reducing system implementation costs and engineering difficulty, effectively improving the system monitoring capability in densely overlapping electromagnetic environments, and providing an efficient and engineered solution for transponder pulse signal separation tasks in scenarios such as air traffic surveillance and low-altitude airspace management.

The present invention relates to the field of string meter identification, and more specifically, the present invention relates to a method and system for identifying a non-household string meter of an electric energy meter. The method comprises: presetting the number of check code bits of a message signal, constructing a reference window of target data, converting power detection data into binary data, and calculating a first abnormality of a target code bit in the target data; obtaining filtered binary data, and calculating a second abnormality of a target code bit in the target data according to the binary data and the filtered binary data; taking the product of the first abnormality and the second abnormality as the total abnormality of the target code bit; calculating the possibility of correction of the target data, traversing different check code bits, and taking the number of check code bits corresponding to the maximum correction possibility as the final check code bit, which is used to receive a message signal to complete string meter identification. Through the technical solution of the present invention, the accuracy of signal output can be improved, thereby improving the speed and accuracy of string meter identification.

The embodiment of the invention provides a robot control method and device, electronic equipment and a readable storage medium, and belongs to the technical field of robots. The method comprises the steps of performing instruction decoding on a task file according to a preset dictionary to obtain at least one to-be-executed instruction, and storing each to-be-executed instruction into a to-be-executed instruction queue; each to-be-executed instruction comprises a command name, a command parameter and an execution state; reading a head instruction of the instruction queue to be executed as a current instruction; and judging whether the current instruction has a preorder instruction or not, and if the preorder instruction exists and execution of the preorder instruction is completed, executing the current instruction according to the preset dictionary. Therefore, the robot operation instruction is decoded through the preset dictionary, the decoding process is simple, the expansibility is high, complex robot operation can be programmed, the robot operation threshold is reduced, and the usability of the humanoid robot is improved.
