Abstract
This study developed a system for controlling home appliances remotely through mobile phones and investigated the performance of the system. This was with a view to reducing hazards resulting from the use of home and industrial appliances.
Two techniques for control of home appliances were developed. The first technique involved the secured control of appliances via the internet. A Java application was developed and installed on a mobile phone with a Java Virtual Machine (JVM) platform. The application was deployed into Java enabled phones, which communicates through a home server to an embedded system. The second technique involved the secured use of the short message service (SMS) which was developed as an alternative for situations when the internet and the Java application were not supported. The SMS-based control system was developed using a microcontroller-based control module that could both securely send and receive messages from a suitable mobile phone on the Global System for Mobile (GSM). The microcontroller was programmed to carry out the issued commands and then communicate the status of appliances back to the mobile phone. Frame Bus protocol was adopted and Assembly Language was used to enable the mobile phone to control the appliances using SMS. This operation was tested using MTN-Network for coverage distance and feedback response time for 30 samples control commands that gave the status of the appliances in the remote locations. Measurement to compare the effectiveness and efficiency of the SMS and the internet methods were taken, using Ibadan as the base station, at Ilorin (68km), Ife (68km), Lokoja (339km), Akure (193km), Abuja (555km) as remote locations.
The results obtained showed that the secured control of appliances via the internet took an average of 10.1, 10.3, 10.2, 11.0 and 10.0 seconds, respectively; while the average response time for SMS were 8.1, 8.0, 8.3, 8.2 and 8.0 seconds, respectively. It was observed that the internet-based method lagged behind the SMS-based technique by a minimum of 2 seconds. This is due to the longer route and higher hierarchy traversed by the former. Furthermore, the SMS control method has about 2% failure rate. The user name and password was preconfigured, if the authentication is wrong the phone will logout the control application automatically.
This study concluded that the developed system is highly reliable due to the low failure rate achieved, and a minimum propagation delay when sending command. The techniques developed will help to secure and control home and industrial appliances remotely.
