The invention discloses an upper limb joint movement degree measuring method based on a Kinect sensor, comprising measuring projects of measuring shoulder joint buckling / stretching and adduction / abduction, elbow buckling / stretching, upper limb palmarflexion / dosal flexion and radial deviation / ulnar deviation and the like. In a measuring process, a sensing man-machine interaction manner is adopted and a position of each joint of an upper limb is captured through the Kinect sensor according to the movement of the upper limb of a detected person, so as to record, calculate and feed back joint movement degree information in real time, automatically finish measurement and directly obtain a measured result in real time; and therefore, the operation is simple and convenient. A user can select measurement projects by oneself; and in each project, the user can execute the movement of the upper limb according to an initial body position for promoting accurate measurement. When the executing movement does not accord with measurement requirements, a system has an error, and prompts and corrects unreasonable movement and postures by the user in time.

The invention provides a reclosing criterion system for an overhead line and cable hybrid transmission line to ground short circuit fault. The system comprises a field monitoring unit and an analyzing and processing unit, wherein the field monitoring unit performs on-line collection of hybrid circuit signals of the cable body at the cable terminal of the hybrid transmission line and the terminal ground lead, the collected analog signals are sent to the analyzing and processing unit after being transferred and processed so as to analyze and process current values at the two ends of each phases of the cable, and whether the line to ground short circuit fault occurs on the cable line segment is judged. The system has the advantages that according to operation conditions of different ground connection manners of the cable line, the influence on the hybrid line of the overhead line fault and the electric cable fault and the fault features is analyzed, and the current change rules of the cable body and the ground lead of the hybrid line during occurring of the fault are measured and calculated, and the combination of influence on the short circuit fault and the hybrid line of the electric cable and the fault features provides the theory reference for intelligently judging the fault point position and deciding whether to perform the reclosing operation.

The invention discloses a foundation pit top horizontal displacement monitoring method which comprises a longitudinal foundation pit edge monitoring point monitoring link and a transverse foundation pit edge monitoring point monitoring link. The longitudinal foundation pit edge monitoring point monitoring link includes the following steps that 1, firstly a foundation pit corner portion point B1 is selected to serve as a static benchmark point, monitoring points are set on two longitudinal edges of a foundation pit respectively, the monitoring points before excavation are Bi and C i+1 (i=1, 2,......n) respectively, the corresponding monitoring points after excavation become B' i and C' i+1 respectively; 2, before excavation is conducted on the foundation pit, the distance between B i and B i+1 is monitored to be B i * B i+1, and the distance between the B i+1 and the C i+1 is monitored to be B i+1* C i+1; 3, after excavation is conducted on the foundation pit, the distance between the B' i and the C' i+1 is monitored to be B' i *C' i+1, and the distance between the B' i+1 and C' i+1 is monitored to be B' i+1 * C' i+1; 4, the horizontal displacement of the monitoring point Bi and the horizontal displacement of the monitoring point C i are obtained according to the value of the B i * B i+1, the B i+1* C i+1, the B' i *C' i+1 and the B' i+1 * C' i+1. The horizontal displacement monitoring method is high in measuring accuracy and low in requirement for professional skills of monitoring personnel, and monitoring can be finished conveniently just by operation of a single person.

The embodiment of the invention provides a method and a device for visualizing threshold information. The method comprises the steps of firstly receiving a command of a user of setting the threshold; judging whether the set threshold value in the command is in the threshold legal range, if the threshold setting value is legal, executing the command of setting the threshold; calling out the help information in the reference standard value range corresponding to the threshold setting value from the threshold reference standard database, displaying the help information on the threshold setting interface, and displaying and storing the threshold setting result. The method provided by the invention can intuitionally provide the corresponding standard as the threshold baseline and visualize the reference value information, so as to reduce the requirement of professional skill and the probability of unreasonably setting, and avoid the process of looking up the data to reduce the error, thereby improving the efficiency of threshold setting and the user experience.

The invention relates to a geological exploration technology, in particular to a superficial layer geological displacement monitoring and early-warning system and a superficial layer geological displacement monitoring and an early-warning method. The system comprises a sensor module, a communication module, an information processing module and an early-warning module. When a geological accident occurs at the monitoring points, the angle sensor module can monitor the offset, the communication module transmits the monitored offset to the information processing module, the information processing module converts the offset into offset displacement, calculates the offset center and the average offset value of the monitoring point according to the offset displacement, judges whether the average offset value meets the early-warning condition or not and transmits triggering information to the early-warning module if the average offset value meets the early-warning condition, and the early-warning module sends out an early-warning signal according to the received triggering information. The monitoring and early-warning system and the monitoring and early-warning method are high in monitoring accuracy and realize all-weather and dynamic monitoring. The monitoring system is low in mounting, using and later maintenance costs. The monitoring and early-warning method is easy to operate and control and suitable for popularization.
