This paper presents a research of unidirectional AGVS (automated Guided Vehicles System) with battery management in a flexible manufacturing system (FMS) based on simulation. Although battery management is important for vehicle management, this problem is usually omitted in research. It is difficult to research the AGVS in FMS from using an analytic method. So in this paper, a parameterized simulation model of AGVS with battery management is built by using computer simulation. The result verified the reliability of the AGVS, and can be used in the future design. © 2010 IEEE. Source

Rapidly acquiring and real-time transmitting crop water requirement information constitute the basis for achieving intelligent diagnosis and precision irrigation. In order to collect and transmit crop water requirement information at real time, a new microcontroller-based real-time remote monitoring system was designed, including system hardware design, software and anti-jamming design. The system achieved the functions including clock reading, information configuration, LCD display, keyboard control, data sending and receiving, multi-channel information acquisition, conversion and storage. Laboratory and field tests showed that the system can achieve data acquisition and real-time display of the crop water requirement information. Unlike the current weather station, the system collects crop water information, meteorological factors and soil parameters at the same time. It has a high level of stability and acquisition accuracy, and can meet the requirements for real-time remote monitoring of the crop water requirement information for irrigation decision-making. © 2014 Chinese Society of Agricultural Engineering.

One of the many design and control issues of Automated Guided Vehicles System (AGVS) is the AGV fleet size. This paper presents a new solution method to determining the number of vehicles in the AGVS based on Flexible Manufacturing System (FMS). The approach relies on two procedures-estimate and simulation. With estimate procedure, the mathematic method will be used to estimate the AGV fleet size. In the next procedure, the estimate value will be used in the simulation model of AGVS for further study. The reliable number of vehicles can be reached after two procedures. The objective of this paper is to increase the efficiency and accuracy of the process in determining the AGV fleet size. © 2010 IEEE. Source

To determine the energy management strategy (EMS) for a series-parallel hybrid electric vehicle (SPHEV) with stochastic dynamic programming (SDP), the dynamic equations for its power-train and the Markov model for its required power are set up. With the minimum fuel consumption as objective while preserving battery capacity, the EMS for SPHEV is obtained with SDP and implemented online. The results of simulation show that the fuel economy with EMS based on SDP is slightly inferior to that based on ordinary DP, but with SDP-based EMS the battery capacity tends to vary more smoothly, being conducive to the protection of battery.
