Parking Guidance & Management System







Product Title

AG Echo Ultrasonic level sensors measure the distance or presence of target objects by sending a pulsed ultrasound wave at the object and then measuring the time for the sound echo to return. Knowing the speed of sound, the sensor can determine the distance of the object.

How Parking Guidance System works:

  1. Ultrasonic sensor is based on ultrasonic principle where time is measured by emission of sonic signal & return of its echo to determine the presence of vehicle.
  2. Detect, Count and Indicate the vacant places.
  3. Vacancy Indicator & Display Panels are based on L.E.D. technology to minimize power consumption & increase visibility with long maintenance-free life.
  4. Master Controller interface with other Parking devices & Zone Controller manages the information on a car park zone or level & communicates with other Zone Controllers & Master Controller.

Benefits of Parking Guidance System:

  • It is estimated that 30% of traffic congestion during parking is attributed to vehicle looking for parking space (source Traffic Technology International)
  • Cost optimization by progressive openings of levels as necessary. Closed levels can save electricity by switching off lighting.
  • Validation of the premium charged for parking by providing efficient and user friendly parking facility.

Advantages to Parking Area Management:

  • Increase in Car Park Capacity - Due to reduction of circulation space.
  • Increase in Lot Utilization - Lots in hidden / obscured areas get used.
  • Reduces Congestion and Improves Traffic Flow - Drivers know where to go.
  • Vast improvement in the image & ambience of the Car Parking area.
  • Faster Turnaround of Cars into the Car Parking area.
  • Self-Diagnostic Features - Convenient for management.
  • Customer Satisfaction - More likely to return.
  • Statistical Information - Trends can be monitored.
  • Increased Security within the Car Parking area.
  • Increase in Revenue
  • Less pollution
  • Cost Effective Solution

Advantage to Car driver:

  • Shorter Waiting Time at Car Park Entrance
  • Guided to Nearest Available Parking Space
  • No Need to Search, Less Stressful
  • Saves Fuel and Reduces Tyre Wear
  • Gains Precious Time, More time to Shop or Dine
  • Prevent Drivers Fighting over Parking Space
  • Car Parking – A pleasant experience for the motorist

Sensor Sensor

Contoller

The controller is a general‐purpose ultrasonic level controller that provides the end user the ability to control up to three unique devices (pumps, valves and/or alarms) through three relays, namely – Relay1 (DPDT, 2 form C), Relay2 (SPDT, 1 form C) and Relay3 (SPDT, 1 form C). The controller uses three push-buttons, SET, UP and DOWN for configuring the relay operation(s). All of the relays can be used for controlling valves, pumps or alarms.

AG Echo Ultrasonic level sensor which provides accurate range detection, automatic calibration and adaptive noise cancellation in software provide reliable and record measurement. All sensor used 4- stage op-amp based low noise amplifier, second order narrow band pass filter, peak-detector and low-pass filter circuit for detecting even the weakest of the reflected sonar signals. Various output options like pulses width, serial analogue 4 to 20 mA, 0 to 5 Volt etc. are available. Interface circuit options provide RS 232, 4 to 20 mA loop, 0 to 5 V DC, buzzer/relay and seven segment LED display. Accessories like mounting bracket rubber washer/nut faster etc. provide quick design and installation support.

Components:

The controller/sensor unit is offered as per following details.
  1. Controller
  2. Ultrasonic sensor (as specified by the user)
  3. Sensor Gasket
  4. Mounting Bracket
  5. Quick Start Guide

Getting Started:

The controller needs to be configured before installation. The unit features non‐volatile memory, so the set points configured before installation will not be lost when the unit is powered down. To start, all you need is the following information:

  • Basic Tank Information
  • Sensor Distance Value – Maximum sensor range (1M or 2M or 3M or 4M)
  • HEIGHT – Distance from the transducer face to the bottom of the tank.
  • FILL‐H – Maximum fill height of the liquid from the bottom of the tank.
  • Set Points:
  • You will need the measured distance from the bottom of the tank to each set point. These values will all be in the same distance value (default is mm, other units as per user request can be made available) and will all be measured from the bottom of the tank.
  • Power:
  • Provide input power to the controller

Note:

The sensor distance value setting also determines the 4 to 20 mA current span. The Height setting and the Fill‐H setting then determine the mA values for each level position.
