DEVELOPMENT OF DIGITAL HUMAN BODY TRACKIER ALARM SYSTEM USING GPS AND TRANSCEIVER FOR CATASTROPHIC EVENTS' RESCUE OPERATION

Catastrophic events especially natural disasters are one of the most devastating events countries around the world normally experience nowadays. One major problem is that disasters leave some countries with a massive destruction and most of the time it kills and destroys the life of the people. After such said event, the lives of the people would become unpredictable because some of them have might survive would die instantly. This is where the researchers thought of conducting a study that would be useful every time these catastrophic events will occur. The study focused on the development of digital human body tracker alarm system (DHBT AS). The DHBT AS is a device to be monitored by the rescuers who will help the survivors during tragedy. The device is incorporated with GPS and transceiver to locate the survivors. The location in the form of latitude and longitude coordinates will be displayed on the LCD monitor of the DHBT AS. Using the coordinates at wiki map, it would be easier for the rescuers to locate the survivors with respect to the location of the DHBT AS. The device is also incorporated with a buzzer to alarm the rescuers the respective distance between the device and the survivor. The more abrupt the sound of the buzz is, the nearer is the rescuer to the survivor. The DHBT AS has its partner which is the rescue and operation device (ROP) which is to be worn by the victim; According to the tracked number of ROPs, the rescuers will be able to track the location and know the number of persons who still have a chance to live or survive within the 100m radius of the DHBT AS location. Moreover, the Rap device has its button that is to be pushed by the victim to inform the rescuers that they badly needed assistance or help as soon as possible. Pushing the button will allow the rescuers prioritize the need of the respective Rap wearer. The overall system trials gave an average delay of 2.4 seconds waiting time before the GPS satellite locator can give exact location

MICROCONTROLLER-BASED FLOOD WARNING SYSTEM WITH SHORT MESSAGE SERVICE NOTIFIER

Floods are the most common natural disaster and the leading cause of natural disaster fatalities worldwide. Particularly, Philippines is the most-exposed country to typhoons in the world. The most recent typhoons that hit the Philippines are Typhoon Haiyan (Yolanda), Bopha (Pablo), and Washi (Sendong). Each of the typhoons gave destructive effects as it hit the Philippines. In the case of tropical storm Washi, it brought long hours of rapid falling rains that triggered flash flood all over Mindanao. Such flood affected almost 132,000 families (NDRRMC, 2012). The researchers who were all residents of Iligan City, took the high level damage to properties and significant number of lost lives due to flood caused by typhoon Sendong, not only in Iligan City but all over Mindanao last December 2011, as the most important underlying factor to consider the design and development of the Microcontroller - Based Flood Warning System with SMS Notifier (MB-FWSSN) as shown in fig. 1. If only someone could have alarmed everybody that there is an incoming flash flood at that time then lives could have been saved. Thus, this system is focused on providing a forecasting system to the locality through warning devices like light indicators, buzzing sound, and issuing a text message every time the sensors at different water level readings at low, average and high levels are triggered by the water. Text messages are received as shown in fig.2. A graphical user interface as a desktop application for the control center is also added in the system to monitor the water level and serve as a database for the cellular telephone numbers of the affected registered residents. With these adequate components for early warning, this system will aid the residents and local authorities to make necessary precautions before and during the flood. The designed MB-FWSSN prototype for Mandulog River of Iligan City indeed turned on the light indicators, produces a buzzing sound and issued a text message to individuals upon different water level readings at only 5sec to 6.5sec delay from actual water reading
