Design and Implementation of Laiwu Black Information Management System Based on ExtJS

Aimed at the problems of low level of informatization in LaiWu blackpig process and the old way of using paper for date storage, in order to speed upthe informatization development of the process, the LaiWu black pig information management system based on ExtJS is designed. In this paper, the design and realization of the system, as well as the open source framework is illustrated in detail, the ExtJS+SSH(Sturts+Spring+Hibernate)framework exploration model is put forward,and the separation of page and is realized. The result of system operation shows that not only the level of informatization in LaWu black pig process is improved, but also its maintainability and expandability are developed.

Obstacle avoidance system for agricultural robots based on multi-sensor information fusion

A robot for agricultural field operation is developed. A modular structure is used in robot design,and the robot is divided into deceleration and electrical drives device, loading platform, crawler and robot posture detection & control device. GPS is used for navigation and positioning. These sensors, such as Ultrasonic sensors, Infrared sensor and laser scanner etc, are selected. And multi-sensor information fusion algorithm is used for obstacle avoidance. A fuzzy clustering idea is used in designing the obstacle avoidance algorithm and the robot can find the area around the obstacle with the algorithm. All theses create conditions for robot automatic navigation and automatic operation.

Design of Intelligent Monitoring and Controlling System for Foodstuff Deepfreeze

In order to improve monitoring and control level for small and medium scale enterprises, an intelligent monitoring and control system has been designed. In hardware designing, MSP430FG4619 was selected as microprocessor for its topping performance and ultralow-power consumption; and the temperature and humidity can be gathered accurately by SHT71 sensor. The acquiring information can be saved in the memorizer provisionally and can be transmitted by wired or wireless transmission. In fuzzy control system software designing, a prototype for fuzzy control was built in the first instance. On the basis of artificial manipulation experience and specific characteristics of the environment, the fuzzy control system can be built expediently by adding relevant parameters to the prototype. Practice shows that: the fuzzy control system prototype greatly improve development efficiency of intelligent monitoring and control system. The system has a high degree of automation and storage food quality is improved obviously.
