The Research for Electrostatic Spinning Parameters Control System at High Voltage

In electrospinning at high voltage, material temperature, the distance between needle and collecting plate and the situation on pushing on material within needle are factors affecting the spinning quality. The paper used the microcontroller as the core, adopted the stepping motor to regulate collecting plate position driving machinery, got feedback by the displacement sensor. During the spinning process, using the infrared temperature probe to measure the needle, meanwhile controlling miniature stepper motor to advance material within needle in constant speed driving piston. The experimental results show that the system has high control accuracy, temperature accuracy can achieve 0.1°C, spinning interval is 1cm and control accuracy is 0.05mm. It provides technical support for a comprehensive, in-depth a electrospinning research.

Research on the Innovation and Entrepreneurship Talent Cultivation Mode in the Agricultural University

In the context of the “mass innovation and entrepreneurship”, it is a profound significance to cultivate the ability of innovation and entrepreneurship of contemporary university students. Combined with various science and technology foundation projects, a good teaching practice platform should be constructed, innovation team should be formed and teaching staff construction should be valued, thus students’ comprehensive quality can be improved to adapt to the fierce competition of the future society.

Design of Intelligent Water-Supply and Temperature Control System Based on Hot Water Box

This paper uses SCM as the control core to design an intelligent water-supply and temperature control system based on hot water box, which is suitable for the countryside and the edge of the town in summer. This system can solve the problems of water supply and controlling the water temperature for the outdoor bath, and which has the obvious advantages of energy conservation and environment protection, safe and reliable operation, low cost, and applicable functions. The SCM can collect the water temperature in real time from the sensor DS18B20, and water volume from the water level sensor. According to the water temperature and volume in the box, SCM controls the small pump to supply water into the box. The user can set the time of bath through the keyboard. The clock chip DS1302 provides the date and time. The power adopts the green energy of solar panel with 5V and 24V. The design provides the convenience for the peasants, especially for the family with only children and the aged. This system has a certain significance for the science and technology popularity in the countryside. Introduction In summer, hot water box with low cost and convenience is very popular for bath in the rural areas. Hot water box is placed on the roof and cool water is poured into it. The strong sunlight can heat the water for bath or washing clothes. However, the roof is so high that rural people supply water in the box by climbing the ladder, which is dangerous, especially for the aged and boy. In addition, the water in the box is too hot at noon, and becomes too cool after pouring much water. So peasants often bath after sunset, which limits the bathing time. There are some related researches about the hot water box. The grey-box model of a domestic hot water electric boiler is presented [1]. The home-use hot water system is studied to save energy and water in supplement of home-use hot water by means of installing backwater pipeline in parallel with the main hot water pipeline, as well as making use of single-chip computer to realize automatic control and certain intelligent control of home-use hot water supply system [2]. In view of the problems facing with the artificial controlled hot water heating in the greenhouse, a temperature control system for hot water heating based on single-chip microcomputer is designed [3]. A 3-dimensional mathematical model of the hot water tank with two water inlets and internal heat source was built [4]. The thermal performance of solar hot water system with novel water tank is studied, which shows that the average thermal loss coefficient is reduced by 1.35 3.42 W/(m·K), and the average daily efficiency is increased by 2.37% 4.02% [5]. The author studies the improved thermal stratification with obstacles placed inside the vertical mantled hot water tanks [6]. The micro-controller STC89C52 is adopted as the core to design an intelligent water-supply and temperature control system based on hot water box. This system can automatically detect the water temperature and volume, and supply the cool water to control the water temperature automatically. This design solves the inconvenience in the process of bath for peasants in the countryside. Overall System Framework This system includes micro-controller STC89C52, DS1302 clock module, DS18B20 temperature sensor, keyboard, displaying screen, solid state relay and small pump. The overall system framework is shown in Fig. 1. 7th International Conference on Mechatronics, Control and Materials (ICMCM 2016) Copyright

Design of Intelligent Monitoring and Controlling System for Deer Based on Internet of Things

There exist issues of fast environmental degradation, poor intelligence, and low management efficiency with the expansion of breeding deer scale. This paper presents the intelligent monitoring and controlling system for deer based on internet of things (IOT). This system includes multiple wireless sensor network nodes, ZigBee routing nodes, ZigBee Ethernet gateway, server, client and video monitoring devices. Wireless sensor network nodes connects ZigBee Ethernet gateway via ZigBee routing nodes. ZigBee Ethernet gateway access client server to transmit data. Video monitoring device includes video cameras, exchangers, hard disk video recorders and display device. The cameras send the environment information to hard disk video recorder via the exchangers, and the environment parameters can be shown in the screen. Wireless sensor network includes electronic rings, RF read-write monitoring nodes, water and eating monitoring nodes, spray monitoring and controlling nodes, and sunlight monitoring nodes. This system can meet the needs of the deer growth environment, save resources and labor, reduce disease incidence, improve the quality of deer antler and rate of survival, which has important guiding significance to large scale production of deer in the future. Introduction In recent years, the deer production has been paid widely attention. In China, there exist about 600 thousand deer ranking first in the world. Sika deer is the main pharmaceutical economic animals and deer antler have special curative effect, which have been approved by international organizations and experts. As the hometown of Chinese sika deer, Jilin province has the obvious advantages in breeding deer. At present, the deer farms still adopt the traditional breeding method. Unstable product quality, low yield, poor efficiency, severe resource depletion problems exist for a long time due to human factors. A mature system with automatic monitoring and controlling deer breeding environment does not appear. Although the RFID technology based on IOT has been used in the automatic monitoring of pig and cow breeding, the life habit of the deer is different, and deer farms need to simulate the wild environment. So the intelligent monitoring and controlling of deer breeding need to be designed individually. There are rare literatures in China. In 2015 Wu Juxin in Jilin agricultural university wrote a master thesis paper about deer product quality monitoring system based on IOT, which realizes automatic control system in the deer growth environment and precise feeding, and a digital information integrated service management platform was designed [1]. In 2016 Lin Yun uses ZigBee technology to build the sheep farm intelligent sunlight system, and this system can improve the sheep farm environment [2]. In 2015 ZHANG Yan uses IOT technology to build a safety tracebility platform for the whole industry chain of Laiwu pig, in which all data of the whole industry chain including Laiwu pig breeding, cultivation, slaughter, processing, logistics and sales are collected using IOT sensor nodes [3]. In 2013 BAI Hongwu constructs boar management platform based on IOT technology, in which an integrated solution for automatical management, epidemic prevention and food safety of farms is proposed [4]. Zhang Xiaoping studies the intelligent cowshed management system consisting of upper management platform software, transmission equipment, terminal controller and execute components, forming an efficient management mode, which is easy to use and can be 7th International Conference on Mechatronics, Control and Materials (ICMCM 2016) Copyright
