Internet of Things Success Stories Series #3 IoT-based Monitoring and Management Approach for Smart Infrastructures 1. Problem During the last years a spectacular growing of the cities has been produced, being such that by 2050 more than six billion people are expected to live in cities and surrounded areas (Habitat 2010). Such amount of people concentrated in cities means a great challenge for the latter ones in terms of providing autonomous and efficient services assuring their sustainability. In particular, challenges such as water supply, public transport, healthcare, education, security and power supply have already been identified as mid-term targets. So far, the current trend of the market regarding the energy management of infrastructures is that of focusing its interests on energy efficiency in the stage of system design, but only in limit or extreme conditions. In addition, low or no interest has received the exploitation and maintenance of these systems. Another interesting behavior of these companies is they only design and deploy the systems but they do not hold responsible for their operation (at least from the energy point of view). So, after the deployment the owner ends up being the person in charge of this system who owns neither the knowledge nor means to proceed properly. From the point of view of the customer, he is only aware about the initial cost of the system, i.e. the price of the devices, their implantation and maintenance costs. Nevertheless, he is not aware about the cost of the system to be operative, i.e. its daily consumption. Besides, he is neither aware of different optimization alternatives by which this initial cost could be rapidly amortized. All these premises have made customers to acquire the cheaper choice which usually cannot provide an efficient approach regarding the management of energy consumption. On the other hand, there exist other kind of infrastructures like refineries, transport, water, etc. or large growing areas which also need a solution for their monitoring and management. In the latter ones, owners are more and more aware of how precious is a resource such as water. For this reason, they are more and more interested in efficient solutions that are able to monitor the environmental conditions of croplands (humidity, temperature, soil conditions, etc.) so as to know the proper moment to water them keeping always the highest quality of their products. In this context IoT also provides 2. Solution In this context, thanks to the great advance in integration and development of Intelligent Computation Systems which are based on Information and Communications Technologies (ICT) (Jones 2011), and the widespread deployment of sensors and actuators the paradigm of Internet of Things (IoT) promotes (Perera et al., 2013), there exists a great opportunity to develop applications which allow a smarter and more efficient performance of the services provided in cities. IoT allows the interaction among smart objects and the effective integration of real information and knowledge in the digital world. Smart objects are equipped with the abilities of sensing and interacting which allow them to capture real world information with a level of detail never obtained before. This technology is the cornerstone of efficient energy management systems. Despite this technology enables the development of new management systems pursuing energy efficiency, other elements are also required so as to provide such a system. These systems need to rely on a smart management platform that permits both monitoring and controlling the different components of the system (sensors and actuators). Actually, energy efficiency is only reached thanks to the interaction among different actors and entities. They allow the platform to monitor real time information, to obtain feedback of the carried out actions, to take control measurements, to design saving strategies, etc. Internet of Things • Success Stories 60 SERIES #3 - November 2015
Internet of Things Success Stories Series #3 IoT-based Monitoring and Management Approach for Smart Infrastructures Figure 1. City Explorer levels OdinS has successfully applied the aforementioned technologies developing a holistic platform based on IoT called CityExplorer and whose levels are depicted in Figure 1. In this document we describe two different success stories of the application of this platform for managing and monitoring smart infrastructures to two different scenarios. The first one is a deployment inside a bank office where the objective is that of making easier its management as well as pursuing the energy efficiency obtaining notable reduction of the energy consumed of the facility. The second application of these technologies consists in a radically different scenario, in particular monitoring a field crop pursuing the optimization of the irrigation process so as to waste the minimum amount of water needed to maximize the production of high quality barley in this field crop. In the following sections we give more details about these two deployments. Deployment in bank office Let us firstly specify the targets for the customers for this facility. From their point of view an efficient management system must be responsible for providing the most comfortable conditions for their daily work avoiding the workers and users of the facility to manually correct these aspects. On the other hand, the efficiency must also be related to the awareness of the energy consumed by the office reducing it as much as possible keeping always the optimal comfort conditions for the people inside it.
