Psychological testing system and method

The invention relates to a psychological testing system and method. The psychological testing system comprises a human eye image acquisition device and a host subsystem; the human eye image acquisition device is used for carrying out acquiring and compressed encoding on human eye images and transmitting the human eye images to the host subsystem; and the host subsystem is used for processing each received human eye image to obtain a training sample, recording the psychological status represented by each training sample, matching a testing sample with each training sample and taking the psychological status represented by the optimal matched training sample matched with the testing sample as a psychological status represented by the testing sample. The psychological testing method is used for finishing psychological status judgment of a testee by using the psychological testing system and applying pupil area analyzing and positioning, information modeling, KPCA (Kernel Principal Component Analysis) and mode recognition and classification methods. The psychological testing system is simple and rapid to operate; and meanwhile, interference from visible light can be avoided. The psychological testing method is used for realizing accurate positioning of pupils and fine analysis of pupil areas and has high judgment accuracy on the psychological state of the testee.

Error prevention system and method for secondary system anomaly recognition of substation under multiple associated scenes

ActiveCN108053041ASolve the problem of wrong cast and returnImprove coordination and error prevention capabilitiesData processing applicationsCircuit arrangementsPrimary operationPower grid
The invention belongs to the fields of power secondary system abnormal state recognition and misoperation prevention and particularly relates to an error prevention system and method for secondary system anomaly recognition of a substation under multiple associated scenes. According to the method, based on normalization of substation information description and normalization of an operation process, an integrated error-prevention function and an error prevention strategy are deployed and configured in devices at all levels of a secondary system comprising devices, a station server and a scheduling server, and information modeling and recognition are performed on the running states of the secondary devices and the secondary system in the substation; and meanwhile, before primary operation and secondary operation on the substation, whether the operation can cause a system anomaly or misoperation is judged through rehearsal according to a power grid topological structure and the running setting state of the secondary devices, and if the system anomaly or the misoperation is caused, warning or forbidding or prompting is actively sent out through analysis, error prevention and remedy are performed on the misoperation or the abnormal running state occurring in the system, and therefore forward intervention on field operation and maintenance work is realized.

Tower information modeling method for power transmission lines

The invention discloses a tower information modeling method for power transmission lines. The method is characterized in that the power transmission lines are called lines, two ends of the lines are called breaking points, transformer substations are called nodes, each tower is called a sub-node, the lines among the towers are called segments, each sub-node has the attributes of the affiliated unit and geographic position, each sub-segment has the use span attribute, and a dispatching system can directly acquire the affiliated unit of a fault point and the tower corresponding to the fault point through the distance between the fault point and a transformer substation according to the use span information among the towers and timely distribute the fault point to the corresponding unit to perform processing; the construction of the power grid power transmission lines is a progressive process, and the power transmission lines and the towers need to be added, modified and deleted at any time during the construction. By the method, informatization modeling of tower information can be achieved, tower positioning speed and precision can be increased greatly, system flexibility is enhanced greatly, and power business information interaction is facilitated.
