Information of failure events from various network devices and service objects is written into original event list. Correlation analysis is carried out for events read by analyzing and controlling engine from the original event list according to levels of original event and selection of classes. The dynamic analytical algorithm synthetically handles information in each area such as scene of historical fault analysis, dynamic performance parameters of network, dynamic topology information and time character of event etc. comparing with prior art, the invention overcomes disadvantages of overlooking information of dynamic network state, dependent on preset rule and lack of auto study ability etc. The invented method provides effective correlation analysis, fault reason analysis and location in real time when storm of network fault happens.

The invention discloses a multi-sensor and antagonistic drive based dexterous hand control system. The system comprises an antagonistic driven dexterous hand in tendon transmission, a joint angle sensor, a touch sensor in bionic skin, a joint force and torque sensor, a tendon tension sensor, a sensor management module, a driver control module and a central control module. According to the system,perception modes of different levels of force and touch are effectively decoupled, various sense information can be flexibly and comprehensively analyzed under different operating tasks, the control difficulty is simplified, and design complexity and cost of each type of sensor (and the bionic skin with touch) are reduced; and through the central control module of the system, the dexterous hand can avoid excessive relaxation or tensioning of the tendon, joint damping and joint rigidity of each joint can be controlled, the compliance operation and the anti-interference performance and robustness can be taken into account, and the system can still work reliably when the joint force and torque sensor or the tendon tension sensor is partially or completely lacked or works abnormally.

The invention discloses a multi-channel electromagnetic valve current acquisition device which is composed of a single-chip microcomputer A / D processing module (1), a CAN communication module (2), a computer communication module (3), an amplifying circuit module (4), a sampling resistor module (5) and an external circuit module (6), wherein, a sampling resistor selects a precise resistor and is connected in series with an electromagnetic valve circuit which needs to be measured, the both ends thereof are respectively connected with a first-grade operational amplifier, the first-grade operational amplifier extracts the micro-pressure drop at the both ends of the sampling resistor and sends to a second-grade operational amplifier after the regulation of the adjustment amplification times ofthe resistor, a filter resistor and a filter capacitor carries out the filtration of the amplified signals, and the results are sent to the single-chip microcomputer A / D processing module. Then, the processed signals are sent to an upper computer through the CAN communication module. The invention further discloses a method for carrying out the acquisition by adopting the acquisition device. The multi-channel electromagnetic valve current acquisition device has the advantages of high negative voltage resistance, flexible adjustment of the amplification times, high communication speed and highsampling precision.
