This paper presents a design and prototype of an IoT-based health and safety monitoring system using MATLAB GUI. This system, which is called the Smart Health and Safety Monitoring System, is aimed at reducing the time, cost and manpower requirements of distributed workplaces. The proposed system is a real-time control and monitoring system that can access on-line the status of consumable devices in the workplace via the internet and prioritise the critically high location that need replenishing. The system dynamically updates the status of all location, such as first aid boxes, earplug dispensers and fire extinguishers. Simulation results of the proposed system gives shorter path, time and cost in comparison to manual maintenance systems.

Large span bridges are very important infrastructure of the nations. The enormous investment and significance in state economy make them get more and more recognition. At present, the technology of the safety monitoring of bridges is becoming a hotspot in both academic and engineering field. Now, safety monitoring systems of the structures have been applied to many large bridges in the world. Among all these parameters which can indicate the safety status of bridges, the deflection is indispensable. Although there are lots of sensors now used to measure the degrees of the deflection, it is still very scarce that the sensors can be made for long-distance, real-time and automatic online completely. The photo-electricity and liquid level deflection sensors (PLLD) introduced here are cheaper and of better-automaticity and higher precision and can work online continuously without contact. This paper will show the structure, performance and theory of our new sensor based on ARM7 in detail. In the end, a concrete application instance in XiaoGou bridge of ShanXi province will be given.

Bridge Monitoring System

The first long-term bridge monitoring system in Korea was installed in 1995, and many bridges have been maintained by long-term monitoring systems. Recently, reliability of data and cost effectiveness have been increased by advanced sensor technology (fiber optic sensor, RFID, USN etc) and measuring equipment. In Korea, the large-scale project for the safety network integration for long-term smart monitoring systems for bridge structures started in 2007, and this is the second year of the project. In this system, various innovative sensor types are considered. To increase the effectiveness of this network system, an analysis of the problems with the conventional long-term bridge monitoring system and solution investigations are needed. The biggest problems are low durability and data reliability because of noise, and the lack of data applications techniques. Therefore, in this paper, a brief summary of the projects is presented and the state of bridge monitoring systems in Korea is investigated, and various problems and solutions for these problems are briefly suggested.

With the application of Global Positioning System (GPS) echnology using in the field of modern transport, more and more long-span bridges have set up the GPS system to monitor the real-time deformation in safety monitoring system. Nowadays the highest measuring accuracy of GPS technology achieves millimeter, and the sampling frequency can reach 20Hz. It can solve real-time deformation data and adapt to the complexity and poor working environment. Based on the application of GPS technology using in long-span bridges safety monitoring system, this paper set the Huangpu bridge as the engineering project and demonstrate how to apple the GPS technology in deformation monitoring and security evaluation.

Bridge safety monitoring system based on IOT this is a wireless technology. In this system we can install the monitoring devices in the bridge. This monitoring device helps to connect the communication devices to a cloud-based server. we use cloud-based server here because it helps to calculates and analyses the data which sent to monitor. Bridge monitoring system can monitor, analyse bridge conditions and their environment and also detect the nearby water levels, vibration and other safety features. Through the telecommunication devices information obtained is transferred to user. In our cities many of the bridges are built on the river that can be reduced their lifetime has expired but it’s still in use.
