The invention discloses an intelligent heat dissipation apparatus of a computer cabinet. The intelligent heat dissipation apparatus comprises a fixed box, wherein a motor is fixedly connected with the top of the fixed box; the output shaft of the motor is fixedly connected with a first belt wheel through a coupler; the surface of the first belt wheel is in transmission connection with a second belt wheel through a belt; a threaded rod is fixedly connected with the middle part of the second belt wheel; movable blocks are in threaded connection with the two ends of the surface of the threaded rod; air blowers are fixedly connected with the bottoms of the corresponding movable blocks; a ventilating plate is fixedly connected between the two sides of the inner walls of the fixed box. The invention relates to the field of the computer technology. By virtue of the intelligent heat dissipation apparatus of the computer cabinet, the problems of incapability of intelligently controlling temperature in the cabinet and poor heat dissipation effect of the existing computer storage cabinet can be solved; and when the temperature is overhigh, the intelligent heat dissipation apparatus can perform control on the temperature in the cabinet, so that influence to the operation and performance of the computer can be avoided, and the working efficiency of the computer is improved.

The invention relates to the fields of biomedical engineering, computer technology and communication, and specifically discloses an accurate positioning method of a rehabilitation FES signal for stroke patients. The method comprises the steps of wearing a dynamic exoskeleton, defining sensor parameters, performing healthy joint movement, recording exercise data of a healthy joint and the myoelectric signal data of adjacent limbs, and calculating the corresponding motion data of an affected joint and the action time and action point of the FES. The accurate positioning method determines a functional electrical stimulation site and a timing of the affected joint through the healthy joint motion of the patients, instead of determining by the experience of a rehabilitation engineer, by using the principle of time-lapse mirroring, each patient can find electrical stimulation time and action positions suitable for own physical conditions, the FES stimulation on the patients makes the actionof the patient affected joint closer to the action of normal limbs, which can better improve the activation of the brain mirror neurons and promote the rehabilitation of the patients, and the method can help the stroke patients to correct gait during the rehabilitation process to a certain extent.

The invention provides a method for remotely and automatically installing a distributed big data system, and relates to the field of computer technology. The method comprises the steps of a, automatically installing the distributed big data system into a remote computer room; b, specifying the number of nodes needed by each component of the distributed big data system; c, firstly computing the total number of the needed nodes, and remotely installing an operating system needed by the distributed big data system; d, installing each component according to the configured node numbers; and e, configuring the components, thus completing the installation. According to the method, the whole installation time is greatly reduced, and the work efficiency is improved.

The invention belongs to the field of computer technology, in particular to a fatigue-driving detection method based on face recognition, a computer readable storage medium and a terminal device. Themethod comprises the steps of: collecting the face image of a driver; extracting a first sub-image from the face image of the driver, the first sub-image being an image of an area where the eyes ofthe driver are located; calculating a feature vector of the first sub-image; calculating a vector similarity between a feature vector of the first sub-image and a preset reference vector, the reference vector being a feature vector of an eye image in a fatigue state; if the vector similarity between the feature vector of the first sub-image and the reference vector is greater than a preset similarity threshold, determining that the driver is in a fatigue driving state. Through the embodiment of the invention, reliable detection standards are provided for fatigue driving detection of drivers, and the occurrence of traffic accidents can be greatly reduced.
