The ubiquitous sensor networks are widely de- ployed in factory auttxnation as they provide effective measuring solution for instruments. The wired/wireless network module, which provides the interface to connect to the u-sensor network, is needed but there is no perfect standardization about the interface. In this situation, the interface compatibility between measuring instrument can be maintained using the IEEEI451 international standard. In this paper, the Wireless Transducer Interface Mcduie （WTIM） based on IEEE1451.5 was designed. It coxnects to the measuring instnmnt, like the muiti-meter, power meter, and etc., to support the RS232 interface. As these devices cannot connect to network without a mod- ule, we use the WTIM to help these devices connect to network sys- ton. Its ftmction was verified through the ubiquitous network connection and data transfer between monitoring PC and measuring instrument. This technology is expected to reduce cost in order to construct the wireless industry automation system using existing devices.展开更多

However, it is necessary to measure the productivity, so that the system of measurement and control of manufacturing processes are an element critical as to ensure greater visibility of the flow＇s restrictions, minimized when detected properly. In this case, the automation of factory＇s measurement process can effectively contribute to ensuring the effectiveness of the function control of a manufacturing system. It is important to consider that the automation of the system of measurement and control of manufacturing processes, of complex environment, is heavily dependent of IT tools applied directly in the interface computational between the operation systems and the corporate systems. This heavy reliance, if exploited technically properly, allows that automation of the system of measurement and control of production makes the access to time real of availability of manufacturing process＇s data, such as processing time and setup time that it can export to a specialist software in programming production, for example, feasible. In this paper, the automation of the system of measurement and control of production is approached, in order to identify the main possibilities of the design of an information system capable to integrate the flow of information in an environment internal on manufacturing organizations, with emphasis in the digital manufacturing paradigm.展开更多

At present, the industrialization and the urbanization, agricultural modernization in our country obviously lags behind, which hindered the synchronous development of them. Therefore, with the internal relations between the empirical researches, we explore influence of industrialization and urbanization of agricultural modernization and path, to promote three synchronous developments which have important practical significance. Based on vector autoregressive model and game thinking, at the same time, we analysis the influence degree of the industrialization and urbanization of agricultural modernization and path in order to provide experience for the synchronous development of reference.展开更多

Based on the evaluation of various base stocks, thickeners and additives, the formulation and manufacture of the long-life CVJ grease is finalized. Bench tests and vehicle performance evaluation tests have showed that the ‘Great Wall brand’ new polyurea-based CVJ grease can meet the demand of automo- tive CVJ. This grease features an outstanding low and high temperature performance, extreme pressure, anti-corrosion and anti-rust properties equivalent to those of similar overseas greases. Compared with the traditional MoS2 containing lithium based CVJ grease, the performance of the new grease is much better.展开更多

The problems being faced by engineers are increasingly interdisciplinary and complicated because the development of new products and processes depends upon the integration of many different technologies. Expansion of possibilities of already existing fieldbus systems is carried out by means of integration them into Profinet （PROcess Field NET） communications. The lab set-model of vertical integration-for data gathering from smart Profibus PA sensor, data transmission, controllers configuration for Profinet IO direct interfacing of distributed field devices on the Ethernet is discussed in this paper.展开更多

This has led to a series of conflicts between government and villagers over the land. This issue has become the core of the conflict. The present from-top-to-bottom rural planning does not meet villagers＇ needs. Within the rural area, there are close social and organizational relationships, the villagers strongly demand autonomy. This has led to conflict between the state and villagers rights of autonomy. The conflict is ongoing, it has never stopped. For the purpose of this paper, the rural area of Zhejiang Province was investigated. The method of the empirical study was employed in order to comprehensively analyze the developmental stage of urban-rural relations, planning systems, the conflict process, and difficulties in the process of urbanization. The study discovered that the conflict was led by different value orientations between the two stakeholders--the government and the villagers. This resulted in a series of conflicts over land and natural resources and added to the breakdown of relationships on both sides, this was an external manifestation of value orientation on both sides. In conclusion, the paper recommends conflict resolution proposals and measures to be employed at every stage of urbanization.展开更多

In this work, we demonstrate a magnetically levitated/piezoelectric/triboelectric hybrid generator, which does not use complex structure and has high steady output performance. It includes three parts: magnetically levitated generator(MLG), piezoelectric generator(PNG), triboelectric nanogenerator(TENG). The peak power of each is 135 μW, 22 mW and3.6 mW, which are obtained at 1 MΩ, 10 kΩ and 1 kΩ, respectively. The hybrid generator can completely light up light-emitting diodes(LEDs) under the vibration frequency of 20 Hz and the vibration amplitude of 10 mm. It also can charge a 470 μF capacitor.On this basis, we have integrated the hybrid generaor as a power supply into a self-powered tempreature sensing system. The combination of three generators can not only broaden the operating range, but also increase the operating length and sensitivity.This work will extend the application of self-powered sensor in automatic production line and promote the development of industrial control technology.展开更多

In resource- rich areas, there is often an investment bias toward the resource sector because of the existence of a threshold for investment in human capital in the manufacturing sector. Once the resource sector is dominant, it has a particular atwaction effect on the economic factors; its expansion and spread have a viscosity effect on industry families;, and the sunk costs and path dependence that emerge as industrialization evolves have a lock-in effect on the role of resources. This may give rise to development path dependence and the trap of resource advantage, resulting in a self-strengthening mechanism in resource-based economies. The key to escaping this trap is to break down the resource sector＇s original self-perpetuating mechanism and path dependence, introduce learning and innovation, adjust mechanisms far the distribution of resource benefits and realize industry coordination and transformational economic development.展开更多
