Scenarios

 

Six operational scenarios are defined. Each operational scenario is linked to one of the three defined use cases. These scenarios outline the capabilities of the ASSC. Their description is in narrative form for the sake of clarity. The table below lists the different scenarios, the corresponding version of ASSC and their relationship to the AMANDA use cases.

SC01 - Indoor Environment and thermal comfort monitoring

The ASSC is installed outdoors, or in a room or is a wearable. After the initial configuration by the system administrator, it can provide measurements related to heating, ventilation and air conditioning. The ASSC can also serve as a weather monitoring station. Moreover, the wearable version is used for thermal comfort monitoring. The ASSC automatically informs a room controlling system to adjust the heating, ventilation or air conditioning in order to achieve the optimal environmental conditions as predefined by the user. Moreover, an application installed in an end user's smartphone projects the room’s or outer environmental conditions in real-time as well as the thermal comfort levels of the users.

SC02 - Fire detection

The ASSC is installed in a room or outdoors. After the initial configuration by the system administrator, it can provide measurements related to the temperature, humidity, atmospheric pressure, CO2 and VOC levels. The ASSC will be able to detect through the use of data fusion and edge intelligence algorithms the presence of fire and will alert in real-time the occupants and the building’s management office or the owner of the outdoors space. The card will transmit details about the incident to the building’s control system, via BLE and to the closest fire department, via LoRa

SC03 - Continuous occupancy monitoring in a parking lot

The ASSC is installed in an indoors or outdoors parking area. After the initial ASSC configuration by the system administrator, the control system can provide information about the occupancy status of a parking spot. Potential vehicles are detected using the magnetic sensor in combination with the imaging sensor. The metallic frame of the car will affect the magnetic field near the sensor. When a change in the magnetic field is detected, the image sensor will capture a picture in order to confirm or not the presence of a vehicle. Additionally, the measuring of local vibrations, during a car arrival, will be investigated as a method for vehicle detection. Subsequently, the ASSC will transmit the collected data to the city’s parking control system via LoRa wireless communication. Informative displays around the city will show the number of free parking spots in each car park.

SC04 - Asset and people localization with access control

The ASSC is carried by the employees of a company. When an employee wishes to enter the building, he can touch the ASSC on a card reader. The NFC connection transmits the cardholder’s information to a central control system and the door either open or denies access. The ASSC also gives permission for access in different offices according to the employee’s clearance. The same as the entry procedure is repeated to exit the building when his shift is over. Moreover, the ASSC captures the location of the worker either in indoor or outdoor environments and continuously monitors the applied acceleration. The employee can use the touch sensor to change his availability status. Moreover, in jobs with a high risk of accident (e.g. miners), the accurate positioning of a worker is critical as it enhances safety. By utilising the accelerometer along with machine-learning algorithms, the ASSC can detect if the person has fallen and he is unconscious or injured. The ASSC transmits the proper information to a local terminal which projects the status of all employees.

SC05 - Monitor transportation conditions of medicines/vaccines

The ASSC is configured by the system administrator and is placed in containers which contain sensitive medical supplies such as medicines or vaccines. The ASSC collects environmental data and the movement profile during delivery. Edge intelligence algorithms are then used to estimate the supplies’ condition during shipping. The shipping evaluation data will be sent to the supply manager’s smartphone via BLE.

SC06 - Crowd counting for social distancing

The ASSC will be pre-configured by the System Administrator. Subsequently, the AMANDA card will be distributed to the end-users in order to monitor any potential contact with an infected person. In that case, the end-user will be informed accordingly to perform a test and self-quarantine will be suggested to avoid further spreading of the disease. The BLE module will be used as the main tracking mechanism of the system. The utilisation of the AMANDA card as a physical token for contact tracing in epidemics ensures the anonymity of the users.
