Virtual Instrumentation
LabVIEW based building security and monitoring system
Aims
Modern security systems are commonly installed in industrial buildings, offices and most homes. They have different levels of complexity and are implemented using diverse electronic and computing technologies.
Aim of this project is to design and implement building security and ambient monitoring system prototype using LabVIEW, and evaluate its operation using the CIB boards in CWG/02 Embedded Systems laboratory. The inputs to the system should be simulated by dip switches and the built-in transducers, and the outputs by the LEDs and a DC motor.
Objectives
1. Write structured LabVIEW program to simulate PC based security system control panel, connected to sensors and actuators in a building.
2. Design a control panel to display a map of a building and the current state of monitored and controlled equipment. A user of the security system should be able to monitor switches, lights, temperature, alarm conditions, and equipment attached to a control panel.
3. Provide evidence of the development of each stage of the VI. This will consist of producing a report and a copy of your complete software solution uploaded to VLE.
4. Demonstrate a functional (fully or partially) program to your tutor at a scheduled laboratory session. The report and copy of your solution on a disc will be required to be handed in prior to your demonstration.
Tasks
Virtual Instrument for building security system should be able to monitor and control the building and sound an alarm if security is breached. The alert system could be triggered when a number of events are detected from sensors placed around the building. The functionality of this system should include:
1. Alarm system
Intruder Detection: An alarm system with entry control into a restricted area
i) To arm alarm systems enter your chosen code
ii) After 3 seconds the inputted code will clear and will arm. To disarm enter the correct code again.
iii) Sound alarm in case of invalid code entry.
iv) Sound alarm if access into the restricted area was gained through breaking a door or a window
2. Lights control
Based on the measured light level activate the lights in a room eg. If a light level in a room is below a set value, automatically switch on LED lights.
3. Temperature control
Based on the measured temperature and a set value, apply control to regulate room temperature turning on a Fan/Heater. Display the temperature chart over a given time interval (day, week), as well as maximum, minimum and average temperature.
Analogue inputs (AI)
1. Temperature measurement - Thermistor.
2. Light measurement -LDR sensor.
Digital inputs(DI)
1. Switches for code set/reset input
2. Switches - alarm trip switches
Digital outputs (AI)
LEDs Alarm set/reset
LEDs Lights on/off indicators
LEDs Intrusion detection
Analogue output
Fan/Heater - DC motor
Evidence
1- Formal report submitted to Unilear
2- Demonstration of the project
3- A disc containing your software solution. This will include your top level VI and all your sub-VIs which should be saved as a project file named HOME_A.lvproj.
Assessment
Marks will be awarded to:
1- Report - with a clear description of all your design considerations,
developments, testing, discussions and conclusions. 30
2- Structure of your Block Diagram code . 25
3- The use of appropriate subVIs . 10
4- The clarity, functionality and elegance of your Front Panel design. 10
5- Demonstration. 25
Note that this is an individual assignment and as such all the elements within it should be all your own work.
