JUTAI Parking Guidance System

JUTAI Parking Guidance System Solution

Overview

Project Background

With the economy’s continuous and rapid development, city residents own more and more cars. The contradiction between car and parking space is more and more serious in urban areas. Public parking lot can’t meet the increasing parking needs. The urgent problem which is how to take advantage of the limited parking lot to meet the parking requirements needs to be solved. And let car park in the parking lots is the key problem to reduce congestion in urban management.

Parking lots have the following common problems

❀ The administrator doesn’t know how many parking spaces can be used in the parking lots? It can only be figured out by human.

❀ Parkers do not get to know the parking space, and move in disorderly on the road after blindly driving in, which is easy to cause traffic congestion.

❀ The administrator needs to appoint lots of administrative staff to ease the parking of vehicles, which increases management cost for no reason.

❀ It is not possible to timely figure out on the vehicle flow in different time and the utilization rate of parking spaces in different areas, so that administrators can’t make correct decisions to adjust resource allocation, resulting in low parking lot utilization and low earnings.

❀ The lights illuminate the parking space all day long, which consumes a lot of electricity, causing unnecessary waste and increasing management costs.

❀ To achieve high-efficiency, low-energy and high-earning parking management and informatization and intelligentization of parking management, so we have researched and produced an energy-saving parking guidance system on the basis of ultrasound as a detection method. This system is ingenious and excellent performance, and the parkers can know timely the real time vacant parking space and drive in quickly to avoid blindly driving in, to increase the road and parking space efficiency utilization and reduce traffic congestion, and so that reduce energy consumption ,emission of cars and management cost. At the same time, making use of energy-saving switch controls parking space lights, truly realizing the lights on when the car comes, and the lights when the car goes off", which fully saves power and reduces electricity bills.

System Definition

Parking guidance

Parking guidance system is a indication system which enables car to drive in the parking stall smoothly. In the general situation, it refers to smart parking guidance system which guides cars to park in the available parking space. And cars are detected by detector through vacant stall on the screen and the parking condition on the parking light. Drivers can park easily by these information. The system applies to effective guidance and management about in and out vehicles in parking lot. Easily parking and monitoring parking stall make parking lot more standard and orderly, increasing the utilization of parking space.

Ultrasound parking guidance

The parking space uses ultrasound detection technology, which detects reliably every parking space engaged or available. Installing on each parking space ultrasound detector can detect whether there is car on the position or not, and then management system will collect timely all detection in it, in the end the system will releases parking and guidance information on the screen and annunciator through logic calculation.
