Railroad Crossings

This research aims to make a warning light with a microcontroller base as a control system. With the aim of reducing the use of manual systems in general that are in use today. The advantage of this warning light control system is that it functions to reduce the number of accidents that occur and can be used for railroad crossings where there are still no latches that have not been installed on the railroad railroad crossing (wild road). The display of the work system that is made will be monitored using a web monitoring display that supports and is easy to understand. Even though it has some delay in the process, the planned system has run well based on the average delay value. The experimental results show the average delay measured in the system is 0.31 seconds before sending from the node and 0.49 seconds when there is a change in conditions, while when there is data transmission from the node. The measured packet loss on the system is 0% before transmission and fans and 8.88% when data is transmitted from the node.

Outdoor Experiments

The control system for Magnetic Resonance Sounding (MRS) groundwater exploration instrument was developed on the platform of LabVIEW. This system consists of transmission and reception sections. The former transmits current, controls power and acquires current and the latter controls amplifier, acquires MRS signals. In order to improve efficiency of data transmission, Ethernet based on TCP/IP is used in the system. Furthermore, the system has additional functions of pulse moment setting, equipment detection, data processing into pictures and data storage. Through outdoor experiments, it is found that the average error is less than 2%. The experimental results demonstrate the effectiveness and correctness of the system.

Ozonated Water

A method for measuring both dissolved ozone (DO3) concentration and UV absorbance was developed adopting ultraviolet (UV) absorption method (JWWA, 1993) using sodium thiosulfate (Na2S2O3) solution for removing residual ozone in ozonated water. A DO3 monitor based on this method was tested. This method was proven to be effective from experimental results. The performance of the monitor was examined with continuous ozonated water. As a result, the monitor performed stably during about 2 months, so that both DO3 concentration and UV absorbance in the ozonated water could be accurately measured. Therefore, the authors have proposed the new aquatic control system with this monitor for ozonation.

Wheeled Inverted Pendulum

To control wheeled inverted pendulum is a good way to test all kinds of theories of control. The control law is designed, and it based on the collaborative simulation of MATLAB and ADAMS is used to control wheeled inverted pendulum. Then, with own design of hardware and software of control system, sliding mode control is used to wheeled inverted pendulum, and the experimental results of it indicate short adjusting time, the small overshoot and high performance.

Improving network control system---NCS reliability and safety has important practical significance because NCS is a hot research subject in these years. Fault diagnosis methods are researched in this paper according to NCS with long-time delay and data packet loss. Firstly, given a NCS with long-time delay, a state observer is structured. Secondly, make the state estimation error equation equivalent to an asynchronous dynamical system having event incidence constraint according to whether the system having data packets loss. The problem of fault diagnosis is converted to filtering problem through structuring filtering residual system based on the observer, then giving a corresponding filter designing algorithm. The designed fault diagnosis filter system not only make sure the stability of the closed loop system but also make the residual systems norm less than given reduction level. Finally, the simulation results prove that the algorithm can diagnose faults effectively.

Simulation Results

In order to reduce the average path length of the wireless sensor networks (WSNs) and save the energy, in this paper, the concept of the small world is introduced into the routing designs of WSNs. So a new small world routing protocol (SWRP) is proposed. By adding a few short cut links, which are confined to a fraction of the network diameter, we construct a small world network. Then the protocol finds paths through recurrent propagations of weak and strong links. The simulation results indicate that SWRP reduces the energy consumption effectively and the average delay of the data transmission, which leads to prolong the lifetime of both the nodes and the network.
