  • RESIDING NODE SELECTION METHOD AND USER EQUIPMENT

    Disclosed are a residing node selection method and a user equipment. The method comprises: after performing signal measurement on a node to be measured to obtain a reference signal receiving power (RSRP) of the node to be measured, a user equipment selecting a set of nodes to be selected with the RSRP being greater than a pre-set threshold from the nodes to be measured; acquiring node state information about each of the nodes to be selected in the set of nodes to be selected; obtaining respective corresponding bias values Bias according to the node state information about various nodes to be selected; and finally selecting a node to be selected, with the sum of the RSRP and Bias being the maximum, from the set of the nodes to be selected as a residing node. By implementing the embodiments of the present invention, a user equipment can set bias values of various nodes according to state information about various nodes, and can adjust the probability of various nodes being selected as a residing node by means of the bias values when selecting the residing node by using a maximum RSRP policy, so that loads between a high power node and a low power node and between low power nodes can be balanced, and the load balancing degree of various nodes and a resource utilization rate of a communication network system can be improved.

  • Resonance Analysis of PCB Power-GND Pairs

    Liu, Rui   Xiao, Dan  

    PCB Power-GND resonance is important in PI design. This article introduces PCB power-ground pairs resonance analysis methods, based on the comparison of theory calculation and simulation in Sigrity PowerSI via one simple example. The relationship between Z simulated parameter and resonance frequency is discussed, additionally, considering about the impact of excitation source impedance, VRM should be modeled as voltage source and drink IC should be modeled as current source to get right simulation results.

  • Modeling and Simulation of Deicing Vehicle Brake

    Liu, Rui   Tang, Lan   Li, Zhuo Qing  

    Parameters of disc brake are calculated according to overall design requirements of the deicing vehicle. Based on the principles of its mechanical structure, ADAMS is used to set up the 3D model and simulate the braking performance. Simulation results show that the braking force of the model grows sharply and steadily and the braking distance satisfies the national standards. This progress provides a useful method to shorten the design cycles of special vehicle brakes, and to reduce its design costs.

  • POWER SOURCE MODULE AND POWER SUPPLY SYSTEM

    A power source module (10) and a power supply system. The power source module (10) includes: a current detection resistor (101), a first comparator (102), a second comparator (103) and a comparator output control component, wherein the positive input ends of the first comparator (102) and the second comparator (103) are connected to the high potential terminal of the current detection resistor (101) respectively, the negative input ends of the same are connected to the low potential terminal of the current detection resistor (101) respectively, and a first voltage reference (V1) is inserted into the negative input end of the first comparator (102), a second voltage reference (V2) is inserted into the negative input end of the second comparator (103); and the output ends of the first comparator (102) and the second comparator (103) are connected to the input end of the comparator output control component respectively. The solution can effectively reduce the requirements on the output current or power of the power source module by the large-scale integrated circuit (IC) chip, thereby decreasing the cost and space occupied by the power source module in the electronic system.

  • Control System of PDP Lighting Inspection Machine

    Liu, Rui   Liu, Gui Xi   Chang, Peng Ju   He, Wei Hua   Huang, Zeng Jian  

    The test of panel's display effect is a key step in the panel production. Lighting inspection machines test the electrical, optical and surface information of Plasma Display Panels (PDPs). This machine is based on a PLC control system and a color analysis system. The PLC system controls a visual positioning system and links to Manufacturing Execution System (MES) and a panel conveyor. This paper considers the structure design and action workflow of the lighting inspection machine. Multi-layer network is built to connect with the whole production system. Optional operation modes are designed in control program and Man-machine interface is introduced to facilitate the operation.

  • METHODS FOR SEPARATING AND REDISPERSING NANO-MATERIALS

    Methods for separating and redispersing nano-materials include the following steps: adding a kind of nonionic surfactant to an aqueous dispersion solution of nano-materials whose concentration is 10-6-1 mg/mL to obtain a mixture, the amount of the nonionic surfactant is 0.05-1wt% of the aqueous dispersion solution of nano-materials; heating the mixture at 30℃-60℃ for 5-60 minutes; adding a kind of salt to the mixture and the amount of the salt is 0.01-1wt% of the mixture; separating the mixture into a two-phase system with an upper clear liquid and a lower cloud point phase having said nano-materials by centrifugal separating. In addition, by cooling the separated nano-materials dispersion from 30℃-60℃ to 0℃-20℃, the nano-materials can be redispersed reversibly. The methods are suitable for separating and redispersing nano- materials in the field of nano-materials application.
