# OPC UA CAR SERVER with NodeOPCUA

A simple server that represents a car with the follow structure:

* Car (obj)

    * Speed (attr)

    * Accelerate (meth)

    * Stop (meth)

    * Engine (obj)

        * Temperature (attr)

        * Oxygen (attr)

        * Pressures (attr)

    * Sensors

        * Any number of user-defined sensors

### Install from source

    $ git clone "https://github.com/Engineering-Research-and-Development/opc-ua-car-server"

    $ cd opc-ua-car-server

    $ npm install --unsafe-perm

    $ node car.js

### Car model behavioural specs

| Motion Status | Engine | Acceleration | Oxigen | Temperature          | Pressures              | Speed |

| ------------- | ------------- | ------------- | ------------- |----------------------|------------------------| ------------- |

| Stopped | Off  | 0  | 0  | Environmental 20 °C  | [0,0,0]                | 0 |

| Stopped | On  | 0  | 5  | Tends to 80 °C    | Tends to [100,100,100] | 0                        |

| Accelerated | On  | > 0 | Varies with speed. When the acceleration increases an overshoot is triggered, otherwise if acceleration decreases an undershoot is triggered. | Tends to 80 °C     | Tends to [100,100,100] | Varies with acceleration |

| Constant | On | 0 | Constant | Tends to 80 °C     | Tends to [100,100,100] | Constant                 |

| Decelerated | On | < 0 | Varies with speed | Tends to 80 °C    | Tends to [100,100,100] | Varies with deceleration |

| In motion (Decelerated) | Off | 0 | 0 (Transmission Neutral / Engine Brake) | Tends to 20 °C    | Tends to [0,0,0]       | Tends to 0               |

| From decelerated to constant | Off -> On | 0 | Follows the current speed  | Tends to 80 °C    | Tends to [100,100,100]     | Constant               |
