Most drivers would agree that nothing can be more devastating than not being able to find a parking space right when they need it. Not only is it a waste of time, fuel, and energy, it also creates traffic congestion and enraged driver.

mobile apps for parking lot service

Here’s how mobile technology would integrate with parking lot safety equipment.

For starters, we can’t deny the fact that drivers across the nation and around the world are starting to utilize websites, mobile apps, and other technological innovations to find a pay parking the easy way.

Major cities in the US are working on ideas on how to simplify the parking process, and if fate allows, mark a revolution in the parking industry.

The Combination of Several Technological Innovations

Engineers are now trying to combine GPS receivers, ultrasonic sensors, and cellular data sensors to come up with a budget-friendly, yet the highly effective solution for finding the nearest available parking space in the area.

By having a well-managed parking data available, this would alleviate traffic problems as travelers would be able to decide where to park or choose another mode of transportation beforehand.

In such a case that drivers opt for street parking, it could be useful as it will suggest parking spaces to users through the use of a navigation system.

To test this out, ultrasonic distance sensors were mounted on the passenger-side doors of vehicles, and utilizing data collected, the researchers were able to come up with an algorithm that analyzes the ultrasound distance readings into a count of vacant parking spaces. The combination of this with GPS data could also generate maps regarding which areas are occupied.

Traffic congestion is a huge issue, and investing in smart parking infrastructure is a good investment. Fixed sensors can be installed in speed bumps, parking meters, and asphalt to detect the presence of vehicles in these parking spots. The problem with this is that it only works for slotted parking spaces and metered parking space.

Likewise, the installation and operating costs aren’t cheap either. That’s why engineers are also devising a prototype of a sensing platform using an ultrasonic sensor that could report the distance to the nearest obstacle, and a GPS receiver capable of noting the corresponding location. These can be connected to a PC or WiFi card to send data to a central receiver.

The detection of parked vehicles is based on the ultrasonic sensor readings. Through this, it would be possible to distinguish parked cars from other objects in the area. Filters were also developed to eliminate dips that have a depth of less than the recommended threshold.

The Use of Detection Data

Integrating detection data with reference maps to produce a spot-accurate map of parking availability. Those who are behind this innovation faced a significant issue through– the fact that location coordinates offered by a GPS receiver could only gather up to 3 meters.

That means if it’s beyond that, it might be difficult to gather accurate data anymore. That’s why another … Read more ...

In water treatment applications, different types of pumps are selected based on criteria such as:

  • System requirements
  • Flow capacity requirements
  • Discharge pressure requirements
  • Availability of space

The pumps most commonly used in water distribution systems are centrifugal, vertical turbine, and submersible pumps.

1. Centrifugal pumps

“Centrifugal pumps are the most common types of pumps used in water distribution,” says a water industry specialist working for the Woodhams Group. A circular fan or turbine-shaped impeller is mounted on a centrally supported shaft that is rotated by a motor that can be powered by diesel fuel or electricity. When water enters at the center suction a high velocity is imparted by the rotating impeller that circulates the water, throwing it outward.

2. Vertical turbine pumps

Generally used in raw water intakes and at booster stations in a water distribution system. The water is channeled through a cross-sectional, uniform area. A central impeller is situated along the axis with blades shaped in a way that allows the water to flow in a radial direction.

3. Submersible pumps

Submersible pumps are used mostly to pump groundwater from wells and are placed below the water level. It is a multi-stage centrifugal pump with impellers mounted on a vertical shaft. An electric motor that drives the pump and constructed for use in submerged operations is positioned adjacent to the pump.

Water Treatment

Pumping pure water is very different from pumping waste water. Wastewater often contains contaminants in the form of long fibres or other abrasive solids. A lot of aggressive chemicals are used in water treatment operations. Water treatment plants usually make use of continuous flow operations with points in the process for additional treatments such as filtration, dosing of chemicals, disposal of treated sludge, sedimentation, and storage. Some water treatment operations have periodic processes that run only once a day or once a week.

In a professional waste treatment plant a number of processes are involved including:

  • Physical – filtration and flotation
  • Chemical – chlorination, and coagulation
  • Biological – aerobic and activated sludge processes.
  • A combination of all three

Chemical Dosing Pumps

These are positive displacement pumps used for feeding chemicals into the water supply system at various stages of the treatment process. They are suitable for handling fluids with varying viscosities and abrasive fluids such as viscous liquids and acids and for applications that require high pressure. There are two types:

1. Reciprocating pumps

A piston moving back and forth in an enclosing cylinder pushes the water into the cylinder with the help of check valves.

2. Rotary pumps

A rotary pump has an impeller in the shape of a screw, gear, or lobe that rotates within an enclosed cylinder, imparting energy to the water.

Industrial Water Pumps

Industrial water pumps are designed for pumping wastewater with high reliability and efficiency through all stages of water treatment. They are suitable for the following applications:

  1. Sludge treatment – pumping and treatment of dewatered, stabilized, thickened, primary, secondary, and tertiary sludge.
  2. Wastewater treatment
