How do parking guidance system work

There are many things we don't think we need it in our life at a certain time , But now cannot fathom our lives without.

Some things make our life easy and some remove problems we never knew we had.

In This vein, Came the concept of parking guidance system  which is a very useful tool for drivers because it allows them to easily get information about unoccupied parking spots, and find a vacant one quickly.

Whatever the reason is the system is become more and more popular in the parking construtures all over the world.

This guidance page will look at the impacts, features, working principe,functions future and where they can be used

What is parking guidance system?

The parking guidance system can guide the vehicle to enter the destination parking space smoothly. Generally speaking, it refers to the intelligent parking guidance system that guides the vehicle into the empty parking space in the parking lot. The detector detects the parking space, and the empty parking space information is displayed on the display screen. The driver can easily park through this information.

Important Parts Of Parking Guidance System

The system consists of three parts, namely data acquisition system, central processing system, and output display system.
data collection system
① Install an ultrasonic probe directly above each parking space (the address of the ultrasonic probe can be set according to the site conditions, starting from No. 1 in order and gradually increasing), and 8 ultrasonic probes are connected to a probe controller through the RS485 bus; (also can be transmitted by radio frequency)
② The probe controller summarizes and processes the collected parking space status information through the RS485 bus, and then connects to the acquisition terminal through another RS485 bus. The probe controller can also control the parking space lights and parking space status lights according to the collected parking space information. Up to 16 probe controllers (the address of the probe controller can also be set according to the site conditions, starting from No. 1 in order and gradually increasing) can be connected to one acquisition terminal;
③ The collection terminal transmits the parking space information collected from each probe controller to the data processing center (collection terminal numbered 1) through the CAN bus. Up to 32 acquisition terminals can be connected to the CAN bus.
④ The data processing center (the acquisition terminal numbered 1) transmits the collected data to the PC for management in real time through the serial port (RS485 bus). The PC then processes and counts the parking space information. The data processing center can also download the information to the acquisition terminal through the CAN bus, and then the acquisition terminal publishes it to the nearby empty parking space display screen by wireless or wired to guide the driver to choose the driving route. [2]
central processing system
Its function analyzes the collected data and displays it on the corresponding output device.
① The data on the management PC can be used to publish the relevant data of the system through the local area network or wide area network;
② The data processing center (No. 1 acquisition terminal) can be connected to the GSM wireless MODEM to publish (transmit or receive) relevant data to the urban parking guidance system control center;
③ Release of parking space data in the parking lot: mainly adopt the method of attaching LED indicator screens at the collection terminal. These LED screens are installed at the entrance of the parking lot or at the traffic fork to indicate the driving direction and the number of empty parking spaces.
④ When the vehicle enters a specific area of the parking lot, the parking space indicator (green light for the vacant space) connected to the ultrasonic probe at the front of the parking space is installed to guide the parking person to park the car in a specific parking space. [2]
output display system
It consists of a display screen and a guide board. Working principle Through the parking space detector, the parking space data of the parking lot is collected in real time, the system collects the parking space related information of the parking lot, and sends the information to the central processing system through the data transmission network according to certain rules, and the central processing system processes the information. After the analysis and processing, the relevant processing data is passed through the output device to provide information to the signs and guide signs in the parking lot to guide the vehicle to enter the relevant parking space. For relevant parking space information, the system provides a data query interface
How do parking guidance system work?

Ultrasonic detectors and ground-sensing detectors inspect the real-time status of parking spaces, upload parking status information, and data converters upload parking space information to the guidance monitoring system. Through logical judgment on parking status, preliminary guidance from large areas to local areas is carried out through high-brightness LED red/ Green light parking spaces guide to empty parking spaces
vehicle entry process
1) Before entering the car park, the car owner will know the information such as the remaining space of the car park through the external electronic display device of the car park. After the car is in charge of the card or the card is picked up through the automatic card dispensing machine, the system will first perform identity authentication (legality, validity period, etc.), Then start the camera to capture the whole vehicle image and the partial vehicle image suitable for license plate recognition, apply the license plate recognition technology to identify the license plate number from the captured partial vehicle image, convert the graphic information into a text signal, and then the system automatically assigns it according to the predefined rules. One parking space, and then prompt the owner of the allocated parking space through the entrance LED display screen and the sound effect output of the voice module at the same time. Finally, the system records the entry process in the database, opens the gate, and activates the vehicle guidance system in the field. .
2) Send the license plate number and driving direction information identified from the local car picture captured when entering the venue to the LED guidance screen corresponding to the driving line of the parking space in the venue for display. When the vehicle enters, the owner will follow the direction indicated on the LED guidance screen. Drive and guide the vehicle to the allocated parking space;
3) During the driving process, when the vehicle drives onto the geomagnetic detector, the street lighting control module immediately triggers and turns on the corresponding in-field lighting street lamps according to the preset settings. When the vehicle leaves the geomagnetic detector, the control module will delay for a certain period of time. Time to automatically turn off lighting street lights;
4) After the parking space detector detects that the vehicle has entered the parking space, the system updates the parking space occupancy status, and immediately synchronizes the electronic map or updates the large LED parking lot simulation display; in addition, it can also control the light line guidance system, open the parking space lock or Application of functions such as parking lights. [2]
vehicle exit process
When the vehicle leaves the field, also when the vehicle drives onto the geomagnetic detector, the street light lighting control module will trigger the corresponding lighting street lights in the field. The car map and the partial car map suitable for license plate recognition, and then retrieve the entire vehicle map of the entry and exit for manual comparison, and then identify the license plate number according to the partial car map of the entry and exit for automatic comparison, and finally pass There are two ways to prompt the parking fee on the toll display screen and voice, and then complete the record of the exit data, open the gate and release
Where can the parking guidance system can be used?

The parking guidance system is mainly suitable for large and medium-sized underground parking lots, and is widely used in public parking lots such as government office buildings, railway stations and shopping malls.
