Design of aquaponics system controlled by PLC integrated machine
Xiao Lan;Wang Ruofen;Song Xinyang;Niu Guoling;Zhang Ziyu;Huo Yanzhong;Chen Xinyao;The aquaponics control system is an ecological agriculture model that combines aquaculture with vegetable cultivation. Due to its characteristics of resource conservation,environmental friendliness and high efficiency,it has attracted increasing attention. This design proposes aquaponics symbiosis system based on the control of Delta DIAU integrated machine Under the control mode combined with the PLC( Programmable Logic Controller) programming and HMI( Human-Machine Interface) setting,it can realize the operation of key links such as the monitoring of each pump,sensor,feeding and supply. Both manual and automatic control are adopted to ensure a stable and suitable growth environment for fish,while providing sufficient nutrients for vegetables and realizing the ecological cycle between fish and vegetables.The system can still operate stably in complex environments,demonstrating excellent practicality and adaptability. The research findings can provide technical references for the miniaturized and low-cost applications of smart agriculture.
Application of PK-ByteTrack object tracking algorithm in UAV detection and tracking
Li Sha;To improve the tracking accuracy and stability of unmanned aerial vehicles( UAVs) in complex infrared scenarios,this paper proposes an improved target tracking algorithm named PK-ByteTrack. The algorithm employs the more accurate PCCS-YOLOv8 detector and optimizes the state vector and noise model of the Kalman filter. Research results show that the PK-ByteTrack algorithm improves the MOTA by an average of 3. 8% and reduces the IDSW by an average of 22. 6%,with superior performance in FP and FN control compared with other algorithms. While maintaining real-time processing capability,the algorithm significantly enhances the tracking robustness and trajectory continuity for UAV targets in complex scenarios.
Research on pure pursuit path tracking control algorithm for UAV based on PSO-RBFNN
Han Yonghui;To address the insufficient tracking accuracy caused by the fixed look-ahead distance parameter in the traditional pure pursuit model for UAV path tracking,a pure pursuit path tracking control algorithm based on PSO-RBFNN is proposed through modeling and simulation. The particle swarm optimization( PSO) algorithm is adopted to perform global optimization for the network parameters. The simulation results show that the mean squared error( MSE) of the proposed model on the test set is 0. 0033 m,which is reduced by 55. 4% and 45. 0% compared with GD-RBFNN and BPNN,respectively. In closed-loop path tracking,the designed controller decreases the average lateral error by61. 8%,which significantly improves the tracking accuracy and stability of UAVs under complex operating conditions.
Design and practice of an intelligent monitoring system for greenhouse agricultural machinery linkage based on the Internet of Things
Lyu Linjie;Aiming at the problems of high regulation energy consumption and unstable data transmission in greenhouse environment monitoring,this paper designs an intelligent greenhouse environment monitoring and control system linked with agricultural machinery based on the Io T cloud platform. The system adopts a three-tier architecture of “on-site collection-long-distance transmission-cloud control” and integrates a hybrid LoRa + Wi-Fi network to achieve reliable data transmission. Experiments show that the mean absolute error( MAE) of temperature after fusion is reduced to1. 001 ℃,with a mean absolute percentage error( MAPE) of 9. 98%; the communication success rate of the system exceeds 99. 8% in a 40-meter sheltered environment,demonstrating good practicability and stability,which provides a reference for the intelligent transformation of greenhouse agricultural machinery.
Research on automated navigation methods for agricultural machinery based on computer vision and multi-sensor fusion
Qiao Dan;To solve the problems of low navigation accuracy,unstable path tracking,and insufficient environmental perception ability of traditional agricultural machinery in unstructured farmland environments,this paper constructs an automatic navigation system for agricultural machinery based on computer vision,and combines multi-source sensing information( IMU,GPS,Li DAR data) to achieve visual recognition of work paths,inter row boundaries,and obstacles through image preprocessing,object detection,and feature extraction. Based on fuzzy PID and model predictive control( MPC) strategies,the steering angle and driving speed are dynamically adjusted to minimize path deviation and improve operational stability.

Research on Educational Dynamics Mechanism of School-enterprise Cooperation in Mechanical Manufacturing in Applied Undergraduate Colleges and Universities
YU Zhenzhen;YIN Ningxia;ZHANG Jing;WANG Hongxuan;Applied undergraduate colleges and universities in mechanical manufacturing professional education in the school-enterprise cooperation teaching mode can make up for the gap between the combined theoretical education and the actual industrial demand, enrich the students' practical experience, and cultivate more market-adapted high-skilled talents for the mechanical manufacturing industry. This paper is based on the economic interests and social responsibility perspective, to build the mechanical manufacturing professional enterprises to participate in school-enterprise cooperation under the education power system, using case study and questionnaire survey method on 32 different sizes and types of enterprises, the results show that the primary motivation for enterprises to participate in the cell cooperation for the value of social responsibility and the pursuit of the enhancement of its brand image and social influence, and at the same time, can also be obtained from the potential R&D cooperation opportunities, and internal motivation because through school-enterprise cooperation they can cultivate suitable talents for the future technological development and innovation layout of enterprises. Based on this, this study provides suggestions on the future development direction of school-enterprise cooperation, aiming to promote school-enterprise cooperation to innovate cooperation modes and strategies to quickly adapt to the fast-changing industrial environment, and the results of this paper can provide insights for understanding and optimizing the cooperation between applied undergraduate colleges and enterprises in the professional education of mechanical manufacturing.
