Comprehensive Study

Abstract Several accessories have been developed to aid the wheelchair-confined individual in retaining their social independence. However, after a comprehensive study it was determined that a device, which would automatically extend the immediate reach of the handicapped individual, could not be easily added to such currently existing wheelchairs. We proposed a device that could easily be attached to the back of the electric wheelchair. This unit contains all necessary hardware to support the movement of an actuating arm whose intent is to automatically deliver and retrieve objects outside the person’s immediate reach. In addition, the unit does not significantly exceed the dimensions of the chair so as to not obstruct its normal use. To maximize our efforts, we re-evaluated the creativity of its construction: This was done to optimize its durability, reliability, and ultimately lower its construction cost. The ease of its manufacturing supports our intent for a universal application so that all handicapped individuals could benefit from this device as an after-market electric wheelchair accessory. Achieving these types of functions required the development of two pneumatic telescoping arms that can match and overcome its maximum load of 15 lb., and an electrical control system that both develops arid defines all object motions. A comprehensive static and dynamic analysis was performed to, determine the forces governing the motion of the arm as well as to predict its operating speed and direction. This analysis also tests the boundaries of our control system. This information allowed us to determine the range and limitations that defined the electrical as well as mechanical components of this system.

Fueling Station

More and more LCNG fueling stations being built in several cities of China, it brings some problems on safety ensuring, rapidly constructing, cost saving, stable controlling, convenient moving. According to the requirements of the technological process, a kind of skid-mounted LCNG (Liquefied Compressed Natural Gas-engines) fueling station is designed. The station integrates those main equipments, such as LNG cryogenic pump, LNG vaporizer, and electrical control cabinet. Using a touch screen with a PLC in the electrical control cabinet, and it is an easy and less cost way to discharging the field controlling. The control system structure and the software are also designed for stable controlling. Compared to traditional CNG fueling station, it can be less land consumption, low construction cost, easily moving, and the skid-mounted LCNG fueling station has very wide application foreground.

The Internet Of Things

Wheelchairs are mobility devices that are often used by people who have difficulty walking on their feet, due to illness, injury, or disability. Most of the wheelchairs that exist today are still using the manual system. Ideally, a wheelchair is needed so that users feel free and comfortable in adjusting the wheelchair movement according to their wishes. This study aims to make an innovation in the form of designing an electric wheelchair based on the internet of things (IoT). In this tool, there are several integrated electronic components such as NodeMCU, voltage sensor that is connected to the android smartphone application. Delphi XE8 software functions to create control applications that can be controlled via a smartphone. The control system on a smartphone uses an internet connection to process the wheelchair control system. This tool is very dependent on the connection and stability of the internet network. Design of electric wheelchair based IoT, has the performance that a wheelchair can carry a maximum load of 30kg at a speed of 0.79m / second, plus an accumulator / battery load and a 6.4kg DC motor, so that the total load can be under of 36.4kg.

Intelligent Wheelchair

AbstractThe electric wheelchair gives more autonomy and facilitates movement for handicapped persons in the home or in a hospital. Among the problems faced by these persons are collision with obstacles, the doorway, the navigation in a hallway, and reaching the desired place. These problems are due to the difficult manipulation of an electric wheelchair, especially for persons with severe disabilities. Hence, we tried to add more functionality to the standard wheelchair in order to increase movement range, security, environment access, and comfort. In this context, we have developed an automatic control method for indoor navigation. The proposed control system is mounted on the electric wheelchair for the handicapped, developed in the research laboratory CEMLab (Control and Energy Management Laboratory-Tunisia). The proposed method is based on two fuzzy controllers that ensure target achievement and obstacle avoidance. Furthermore, an extended Kalman filter was used to provide precise measurements and more effective data fusion localization. In this paper, we present the simulation and experimental results of the wheelchair navigation system.

The fault diagnosis of electrical control system of certain type mine sweeping vehicle is difficult due to its complex structure and advanced technique. So in the multi-sensor failure diagnosis process, as a result of various reasons, such as the existence of measurement noise, diagnosis knowledge incomplete and so on, it makes the fault diagnosis uncertainty and affects the reliability and the accuracy of the diagnosis result. This article according to the analysis of electrical control system's fault characteristic of the mine sweeping plough’s, proposes a technique based on data fusion fault diagnosis method. The diagnosis process is divided into the sub system and the system-level, the subsystem uses the BP neural network to classify the fault mode, the system-level uses the D-S evidence theory carries on the comprehensive decision judgment for the whole system's fault. Application shows if some sub-neural network diagnosis has error, using D-S evidence theory fusion can effectively improve the accuracy of diagnosis.
