Project Overview

Stanley Access Technologies (Farmington, CT)

• Dura Glide Slide Door System: Number one in sales
• Aluminum panels that are driven with a motor and a belt system

Stanley needs a system to diagnose problems in the automatic doors

• Design a system that interfaces with the Door Control Unit (DCU)
• System detects anomalies and reports via bluetooth to an Android App to technician with

recommendations

• Joint project with CSE

Our Job (Simple Overview)

• Detect and communicate currents and voltages for all possible components (currently

both sensors, motor) – For the troubleshooting app to be effective, it needs all relevant information

• Voltages and currents from components
• Error codes from DCU and Terminal Block connector errors

– Both of these already in current system – Communicate this data through bluetooth

• DCU already has communication through bluetooth set-up

– Direct communication

• Currently working on Dura Glide Slide Door System

– Project needs to be scalable, or easily upgraded, so it can be implemented on different types of doors when needed

Setup

Dura-Glide Automatic Slide Door System

• 1. Motor 1
• 2. MC521 PRO Control Box

(DCU)

• 3. SU-100 Motion Sensor
• 4. Solenoid Lock

Motor 1

• Requires a voltage supply of 120VDC

– From DCU

• Armature resistance of 12 Ohms
• Connected to a relative encoder
• Controlled by DCU, DCU controlled by

rotary switch/encoder

Sensors

SU-100 Motion Sensor

• Unidirectional or bidirectional sensing

– Senses motion at a threshold of 2 inches/s Stanguard Threshold Sensor

• Powered by DCU (14V) 1A max
• Reflective infrared sensor

Fall Semester Timeline

Motor Test- Total Input Voltage

DC voltage supply to Motor DC power supply to the door system

• Measured door voltage is

117V RMS. Rated voltage is 120V RMS

• Motor supply voltage is 91V

RMS

Motor Test- Motor Voltage

Motor voltage when door open Motor voltage when door close

• 85V RMS which it is below

the motor rated voltage 120VDC

• Different direction
• Armature resistance 12 ohm

Brief Design Structure

Design Solution

Microcontroller:

• Need a microcontroller that can connect with the DCU, sensors and

bluetooth.

• Needs to transmit all of the information (a lot of information from DCU,

relatively little information from sensors) to the bluetooth.

• Need microcontroller with adequate ports for the bluetooth connector.

Current/ Voltage Sensors

• Sensors to monitor motor, lock, and the sensors
• Needs to communicate with our choice of microcontroller
• Need to be able to handle the maximum readings values we can get get

from each source (especially when it malfunctions)

• Needs to read information without disrupting

ACS714 Current Sensor

Budget

Stanley provided spare equipment and components ACS714 Current Sensor (x4) $8.95 ATmega328p with ethernet mod $44.13 ATmega328p XMINI $9.13 Total Budget $79.93

Short Term Goals

• Testing the current and voltage limit of every component

including sensors and motors

• Current/voltage sensors selection
• Microcontroller selection
• Wire connection between the current/voltage sensors and DCU

component

• Make sure the communication between DCU and microcontroller

has minimum error

Long Term/ End Goals

Measure and communicate all relevant information

• Measure

– Voltages and currents from solenoid lock, motor, sensors – Picking the correct sensors and implementing them

• Correct ranges for input/output
• Analog or digital output
• Communicating

– Through DCU

• Use already established DCU-Bluetooth-Android communications
• DCU has spare I/O, but lacks analog digital convertor (unclear if needed)
• ATmega328p

– Has adequate ADC – Direct Communication

• Set up direct communication from sensors to app

– Not preferred, requires new communication connections, as well as more bluetooth adapters
