Aiming at the current wear detection of vertical shaft rigid tanks, which cannot directly know the wear value and directly observe the operating conditions of the tanks, a rapid detection method for the wear detection of the tanks is designed. Use Halcon image processing technology to complete the image processing of the tank road image information collected by the industrial camera, and integrate image preprocessing, shape-based template matching and geometric measurement algorithms into the Qt Creator platform, using the UI interface on Qt Creator Realize the functions of display, data storage and early warning of tank wear data. The reliability of the detection technology is verified through experiments, and the experimental tests show that the detection technology can be used for actual detection. © COPYRIGHT SPIE.

In this paper, focusing on the problem of dynamic monitoring of existing coal mine metal hoisting derricks, a wireless system for real-time dynamic monitoring of metal derricks based on wireless communication is proposed. On the basis of the original single sensor device, the system monitors the partial force of the metal derrick, the state of the sky wheel, the main body tilt and vibration, etc., through the system integration structure, the various monitored information is gathered together for viewing The data obtained is sent to the AP base station wirelessly through a wireless acquisition device using multiple XLAI analog signal acquisition modules and M series RS485 data acquisition modules, and the AP base station uploads the information to the main control computer for intelligent display, and sets the early warning value for early warning. Field tests show that the design can meet actual needs, can effectively monitor the lifting derrick dynamically, and can make timely and accurate judgments and processing for various fault information, and improve the safety performance and production efficiency of mine operations. © COPYRIGHT SPIE.

Aiming at the requirements of motion stability and work efficiency in the actual working process of industrial robots, a time-optimal trajectory planning method for industrial robots with six degrees of freedom is proposed. Taking the six-degree-of-freedom robot PUMA560 as an example, a cubic B-spline curve is used to connect each adjacent path point to express the trajectory, and then the B-spline function trajectory is modified through an improved genetic algorithm to make the robot arm complete the work under the condition of joint constraints with the shortest time. © COPYRIGHT SPIE.

Aiming at the problem of low accuracy in fault diagnosis of mechanical bearing in coal mine. A method based on CS-fuzzy neural network and wavelet packet transform is proposed for bearing fault diagnosis. Firstly, the collected data is processed by wavelet packet decomposition and reconstruction, and the fault feature vector is established. Then, the CS-fuzzy neural network based on improved cuckoo search algorithm is used to identify and diagnose the bearing fault type. Through experimental verification, the combination method of wavelet packet decomposition and cs-fuzzy neural network can diagnose bearing fault more accurately and quickly. © COPYRIGHT SPIE.
