2.4.5 Remote Health Monitoring

The remote health monitoring application takes place in extreme environments. It support humans during deployment with the goal to increase operational safety. To achieve this goal smart textiles measure health quantities of the deployed persons, that

a medical advisor analyses remotely. The system allows mission personnel to create and plan, as well as monitor missions.

The following section describes the Smart Object taxonomy as it builds the foundation for the top-level design.

Smart Object Taxonomy Extension

The remote health monitoring application extends the base-metamodel with five new Smart Objects within the Remote Health Monitoring CPS application: an Instruction Receiver, a Sensor Garments, a Medical Advisor Application, a Secure Data Collectorand a Commander Application (Figure 2.14).

TheInstruction Receiver is able to display instructions to a deployed worker. It uses a stereotype wearable. The Sensor Garment is a smarttextilethat monitor()s health data quantities such as temperature or heart rate. TheMedical Advisor Applicationis a tablet application that enables medical advisors to create advises that are sent to the mission commander. Moreover, a medical advisor selects deployed workers to receive detailed information about them. For each deployed worker, a physiological fingerprintcan be

shown. The Secure Data Collector of typesmartphone is able to collect data, tosend instructions, to assign suits to a deployed worker using the createSuitmapping method and to offer a setup process. With theCommander Application a mission commander is able toinstruct a deployed worker. Mission Details are accessible as well as aselection of a specific deployed worker is possible.

Figure 2.14: Smart Object Extension: this taxonomy extends the Smart Object taxonomy as shown in Table 2.1 and reuses the already definedstereotypes.

Top-Level Design

The top-level design of the remote health monitoring CPS application is shown in Figure 2.15. We defined six cyber-physical systems. Two main cyber-physical systems define the Danger- and Secure Zone. Within the Danger Zone one to many Deployed Workerexist. Each of the Deployed Worker possesses aProtective Suit. TheSecure Zone contains one to many Health Monitoring Systems and one to many Mission Monitoring Systems.

The cyber-physical system of the Deployed Worker contains a Deployed Worker from type Person. Such a Person uses the Protective Suit and uses the Secure Data Collector to setup the cyber-physical system. Moreover, the Secure Data Collector is able to collect data from the Protective Suit, to send instructions to the Instruction Receiver and to create the suit mapping which is necessary to assign the measured data to the corresponding Deployed Worker.

Figure 2.15: Top-Level Design: the top-level design divides the system in two major cyber-physical systems, theDanger Zoneand theSecure Zone. TheDanger Zone contains two other cyber-physical systems, one or more Deployed Workers and a Protective Suit. The Secure Zone consists of one-to-many Health Monitoring Systems andMission Monitoring Systems.

The Protective Suit contains a Sensor Garment that monitors health quantities of a Deployed Worker, such as heart rate and body core temperature. Moreover, the Protective Suit provides an Emergency-and a Status Button. Both are attached to the Protective Suit. An Instruction Receiver is a wearable device that is able to display instructions, which a Mission Commander sends.

Within theSecure Zonea Health Data Broker is able to handle all data flows within the remote health monitoring CPS application. It processeshealth data,position information, instruction(s), status information and emergency requests, advise(s), warning(s) and stress level(s). To evaluate health data a Physical Limit Detector of type Reasoner is implemented. To predict stress levels a Stress Prediction System is deployed.

A Medical Advisor is part of one Health Monitoring System. The Medical Advisor uses the Medical Advisor Applicationto advise the Mission Commander, to selecta deployed worker and toshow the physiological fingerprint. Within theMission Monitoring System a Mission Commander uses the Commander Application to instruct a Deployed Worker, to show mission details and to also selecta Deployed Worker.

Figure 2.16 shows the realized implementation of the Sensor Garment. It uses a Core Temperature Sensor, twoHumidity Sensors, three ECG Electrodes and four Temperature Sensors for the wrist and ankle temperature. The Sensor Garment uses litz wires and cable fabric to connect the sensors to the Data Device of type Reasoner. Details about

Figure 2.16: Smart Object Sensor Garment: the figure shows the Sensor Garment, which consists of objects reused from the base-metamodel (Figure 2.3). It comprises different kinds of Sensors, two Connections and one Reasoner. the CPS application on layer M0 of the MOF can be found in the Appendix B, as the results are currently being published.
