The plant field is filled with various failures and errors every day. However, these failures and errors have been handled by the field inspectors manually on a daily basis. We present for the first time in this paper a design and implementation of a wireless sensor network-based field inspection solutions.Using this system, an embedded device can be carried and used on the field. The work tasks and processes in the plant field were analyzed to develop the field inspection management system. In addition, we propose a set of security measures to protect the embedded system from stealing and altering information. It is due to this system that error information collected on the field can be effectively managed.
The prevalence of portable devices such as smartphones or tablet PCs has been on the rise for a number of years. This type of portable device is called an embedded system and is designed to perform a specific function. In fact, almost all embedded systems have a small size, so users are able to use them as additional components of other devices or to construct specific applications using them [1–5]. Even so, due to the increasing speed of microprocessors and the amount of flash memory or SDRAM available, embedded systems are now capable of completing more complex programs. As a consequence of the advent of database management systems for embedded systems, embedded systems are capable of installing a database management system and play the role of secondary servers [6–8]. During this time, it is expected that the new and rapid developments in ubiquitous technology will not be confined to a few specific areas but will spread to every aspect of humaDifferent sensors are scattered about a ubiquitous environment, and they collect information about the environment around us, such as the temperature, humidity, and illumination.re, humidity, and illumination. Furthermore, ZigBee wireless communication can be used to estimate an individual’s current location [9–11].
Each and every day, various errors and failures occur in the field of plants. Many of these are manually recorded and the record process has a number of issues. Therefore, in this paper we analyze the work tasks and processes in the plant field and we develop a sensor network-based field inspection management system.
Managing a Business
Several types of equipment are in use in the power plant, the equipment is in operation 24 hours a day, and there is a problem of some sort. By resolving these problems, the power plant will be able to operate safely and efficiently. These problems can be discovered during a field inspection. A field inspection management system based on embedded systems and wireless sensor networks is designed in this paper in order to facilitate the existing record process in the power plant. These devices are easily portable and have a low power consumption. The fact that these devices have this characteristic means that they are not to be used in restricted areas because critical data stored on the devices could be stolen or altered by external or unauthorized individuals. Additionally, we propose security measures to prevent the information in the embedded system from being stolen or tampered with.
Figure 3 depicts the proposed architecture of the system. In embedded systems, Linux is installed on flash memory since a hard disk is not present. The resulting device is small and thin. Additionally, SQLite is installed as a database management system for storing and managing status and error data. We developed a TFT/LCD field inspection management system using Qt graphics libraries. Field inspection management systems consist of information management modules, status information collection modules, error input modules, and security modules.
