The invention relates to the technical field of electric power inspection and maintenance robot control, and discloses a power transmission line crawling robot lifting self-adaptive shake suppression control method and system. The method comprises the following steps: acquiring three-axis acceleration and three-axis angular velocity data of a robot platform, calculating a yaw angle and an angular velocity of the robot platform relative to a vertical balance position, and constructing an evaluation index representing the shaking strength of the platform; according to the shake strength evaluation index, driving parameters of a lifting motor are dynamically adjusted through a nonlinear mapping relation; and the swing period and phase of the robot platform are monitored, and when the platform swings to a specific phase point, an instantaneous driving pulse is applied to a lifting motor to consume swing energy. By means of the method, the maximum swing angle of the robot platform can be reduced by 60% or above, the static time after the robot platform reaches the target position is shortened by 70% or above, and the working efficiency is remarkably improved.

The invention provides train control equipment and a train control system. The train control equipment comprises a plurality of virtualization control units, a current switch and a central control unit, each virtualization control unit is obtained by carrying out virtualization processing on hardware resources of the unified physical hardware platform, and is used for receiving a control instruction, sending the control instruction to at least one corresponding train subsystem and collecting state data of the train subsystem; the current switch is electrically connected with each virtualization control unit through a communication bus and is used for forwarding the received control instruction to the corresponding virtualization control unit and forwarding state data returned by the virtualization control unit; and the central control unit is electrically connected with the current switch through a communication bus, and is used for generating a control instruction, sending the control instruction to the current switch and receiving the sent state data so as to perform control operation on each train subsystem. According to the train control equipment, train wiring is simplified, the maintenance cost is reduced, and the real-time performance of data interaction is improved.

The invention relates to the technical field of talent management, and discloses a talent ability evaluation and post matching system based on a knowledge graph, and the system comprises a data processing module which collects individual information and target industry information, converts the individual information into an individual ability vector, and converts the target industry information into an industry demand vector; the graph construction module is used for constructing a cross-industry knowledge graph through multi-source knowledge fusion; the skill migration module is used for calculating skill migration complexity and a capability gap vector; the path planning module is used for generating a plurality of transformation paths and selecting an optimal transformation path based on a transformation path scoring function; according to the method, accurate matching of individual capabilities and post requirements is realized by constructing the cross-industry knowledge graph, and cross-industry skill migration paths can be identified, so that the system can discover potential matching opportunities which are difficult to identify by a traditional method, and the most suitable development paths are recommended for individuals.

The application discloses a motor signal acquisition method, device and motor control system. The motor signal acquisition method comprises the following steps: a FlexPWM generates an overload signal according to a sampling start signal; a cross trigger module starts cross trigger judgment according to the overload signal, so that trigger comparison values of each to-be-tested signal are cross triggered with values of a counting signal; when the trigger comparison value of the to-be-tested signal is equal to the value of the counting signal, the cross trigger module generates an acquisition trigger signal of the to-be-tested signal; in the process of cross trigger judgment, the cross trigger module changes the trigger comparison value of the to-be-tested signal or the maximum value of the counting signal according to an instruction of an upper computer, so as to adjust the acquisition time of the to-be-tested signal; and an analog-digital conversion module opens a sampling channel of the corresponding to-be-tested signal according to the acquisition trigger signal of the to-be-tested signal, so as to acquire the corresponding to-be-tested signal. The application can improve the flexibility and efficiency of signal acquisition.
