Abstract: the application of Internet of things (IoT) technology in solid waste management was analyzed, including key areas such as municipal solid waste (MSW), medical waste, hazardous waste, and waste electrical and electronic equipment (WEEE) management. Elaborates further in various fields of the main form of application and the application level at this stage. Also briefly analyses the trend and the direction of the development of the application.

Abstract: Nowadays, the strategic value of the stratospheric airship attracts more and more attention of the countries. Based on the analysis of the working performance of the stratospheric airship, a cooling system of the electronic equipment is designed and its performance throughout the flight altitude is investigated. The results show that the single cooling system based on cold plate cannot fulfill the cooling task in the extreme hot day and a parallel cooling system as a bench should be designed .meanwhile, the temperature of the cold plate is gradually decreased and then gradually rose with the altitude. The lowest temperature in the process is-35.95°C which would has effect on the performance of the cold plate. Therefore , electrical heating system and frequency regulating speed ventilator are proposed in the above cooling system which is responsible for the electronic equipment at the optimum temperature .

Abstract: If there is no reliability, high-performance electronic devices indicator is no meaning. Reliability design, testing and verification methods of the vehicle electronic equipment are analyzed in this paper, and presented in the industry designed to improve the reliability of electronic equipment ideas, to regulate the reliability of electronic equipment designed to provide a technical basis.

Abstract: Low-voltage power lines are not designed to transmit communication data; it is not ideal channel characteristics using power line as a data communication medium, especially the noise generated by the several of household electrical appliances will have a significant impact on the power line communication system. First, low-voltage power line carrier communication and channel noise characteristics are analyzed, and based on pure electricity environment UPS, the experimental results obtained with different electric appliances for data processing, and analyze the impact of the electric appliances noise on the power line carrier communication.

The design method of virtual maintenance training system for electronic equipment is discussed in this paper based on virtual reality technology. Simulation results show that the system can well implement virtual maintenance training for the electronic equipment, and has certain reference value to develop other relevant system.

Abstract: This article analyses the importance of equipment environment screen (ESS), and analyses the intention, demand and trait of the ESS, and the relatives between ESS and equipment experiment. Besides, it analyses the ESS implement project of printed board, electronic assembly system under the screen of temperature cycle test and random shake environment, and draw some benefiting conclusion.

Abstract: With the progress and development of modern society, various electronic equipments not only have been enriching our lives, but also have become an indispensable tool for people. At present, the electronic equipment is moving towards the direction of becoming more integrated, smaller and more accurate, which requires good dynamic performance and stability. This paper builds the finite element model and makes optimization and analysis for its structure through analyzing the dynamic performance of electronic components. On the basis of the analysis, this paper puts forward a new modeling method having the parametric substructure. In addition, the genetic algorithm is used to dynamically analyze and optimally combine the components on printed circuit boards. Finally through a concrete instance, this paper calculates its rationality and validity.

Abstract: Due to shorter and shorter life span and the rapid development of flat panel display, plasma display panel (PDP) is now becoming a new kind of e-waste. In order to remove heavy metals, such as As, Ba, Cu, Zn, from waste PDP glass, electro-kinetic process was introduced and factors that affect heavy metal removing rate were investigated. Results showed that HNO₃ concentration and PDP adding amount could significantly impact heavy metal removing rate, while current density was on the opposite. Heavy metal removing rate increased first and then decreased as the time extension. When PDP powders was 2 g, 9 mL 5 mol/L HNO₃ was added, current density was 200 mA/cm² and time was 6 h, the removal rate of As, Ba, Cu, Zn were 71.02%, 95.87%, 92.50% and 97.70%, respectively. As, Ba, Cu and Zn distributions in the cathode, anode and middle chamber varied as changing particle size, HNO₃ concentration, current density. Generally, most Cu was concentrated in cathode chamber, and Zn in the anode chamber, while As and Ba would be in both cathode and anode chamber. As, Ba, Cu and Zn, in the middle chamber, no more than 10%, were the lowest among the three.

Abstract: With the development of the modern science and technology, new and high technology and the electronic instrument and equipment has been widely used in the referee work of the large scale track and field matches, which is also a prominent feature of the modern large scale track and field matches. Taking the referee work of the track and field match of the Ninth National Games as an example, this article carries on the discussion on the function of the electronic equipment in the large scale track and field competition, to provide a reference for further deepening the recognition and understanding of the characteristics of the modern large scale track and field matches.

Abstract: In order to study the reliability of the gun contained electronic equipment, take the fire control computer as an example,establish its physical model and then based on the modal analysis theory, dynamics simulation analysis for fire control computer is done by ANSYS. For vibration and shock which cause by the gun firing is harm to the equipment and the measures for vibration resistance is put forward. Through the contrast of the natural frequency of vibration isolated before and after finding that oscillator can effectively reduce the system nature frequency, and this could make the response amplitude is less than the excitation amplitude based on vibration isolator transmissibility curves. It could provide good conditions to ensure the box and its internal printed circuit board to meet the multiplier rule.
