1. Overview of location and parking guidance system
In addition to the management of entry and exit passages in the parking lot management system, how to guide the driver to park conveniently is also an important part of parking management. This plan illustrates a complete meaning by strengthening the safety management of the entry and exit passages of the parking lot, and guidance of parking spaces in the parking lot. Intelligent parking system on the Internet. At present, many existing parking management systems on the market simply manage the entrance and exit passages of the parking lot. In fact, a complete parking lot management system should also include parking space guidance, location guidance, and safety control. The area parking guidance system is mainly used to effectively guide and manage the parking vehicles entering and leaving the parking lot. It is a powerful supplement to the parking lot management system and constitutes a more intelligent parking lot management system.
The system can realize convenient and fast parking for parking users, make the management of parking spaces more standardized and orderly, and increase the utilization rate of parking spaces. The parking spaces adopt composite vehicle detection technology to reliably detect the occupancy or vacancy status of each parking space. According to the specific conditions of the garage, a parking space information display screen is set at the entrance of the garage to dynamically display the remaining number of parking spaces in each corresponding area in the garage and the occupancy of the parking spaces. Set up an area parking information display screen in each area, the display screen can automatically update the displayed data content according to the entry and exit conditions of the vehicle, and dynamically display the remaining number of parking spaces in the area and the free parking space situation. A composite vehicle detector is installed in each parking space to automatically sense vehicle information and feed the information back to the location collector. The data processor automatically calculates the remaining parking spaces in the garage and the occupancy status of each parking space by collecting the information from the location collector, and refreshes the parking space display information in time.
Ruifangda 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 centers. Its main working principle is to detect the reflected waves from the roof and the ground according to the ultrasonic detector from top to bottom, so that it can correctly detect the presence or absence of vehicles in each parking space, and then send the parking information of each parking space through the network line It is sent to the control computer, and the computer passes the guidance signal to the guidance information through software processing. The indicator guides the driver to quickly park the car into an empty space. The main features of the parking guidance system: increase the utilization rate of the parking lot, and better manage the parking lot, reduce the operating cost of large and medium-sized parking lots, and greatly improve the social and economic benefits. Eliminate parking troubles for customers, easily park, save time, and improve efficiency. It is one of the necessary systems for high-end parking lots and a comprehensive manifestation of strength. The AKE parking guidance system shows humanized management from the subtleties, making the parking lot management level even further!
2. System design requirements
A) Set up a remaining parking space display screen at each main entrance of the parking lot to separately display the remaining parking space in each area.
B) A system information screen is set up at each main entrance of the parking lot to display the detailed situation of the area division of the parking lot, which can correctly guide the driver to park according to the easiest route.
C) Set up a parking space display screen at the entrance of each area of the parking lot to display the number of remaining parking spaces in the area.
D) Set up information screens at the turnstiles of all fireproof areas. When an emergency or fire occurs in each area of the parking lot, it can safely guide the driver to leave the parking lot in the fastest way.
E) Set up vehicle detectors in each parking space to detect the idleness of the parking space and transmit the data to the upper-level processor.
3. Design principles and design standards

6. Maintainability: The connection of any part of the system is flexible, that is, the connection from physical wiring to data communication and automatic control equipment is mostly not or seldom restricted by the physical location and the types of these equipment.
4. Introduction to the system structure and function of the location guidance system
Design description: Rui Fonda location guidance system is a subsystem of the parking lot management system, which can operate independently. It can also be connected with a computer, and the total remaining parking space data and driving display are processed by the guide zone master controller. The location guidance system can automatically change the display data as the vehicle enters and exits. It is completely judged and calculated by hardware and has high reliability. Install a vehicle detector at the entrance and exit of each parking space; or install a detector at each parking space; install a guide screen at the entrance of each parking space, and the guide screen displays the total number of parking spaces and remaining Prompt information such as the number of parking spaces. A data collector is installed in each zone, the output signal of the vehicle detector at the entrance and exit of each zone or the idle condition of each parking space is connected to the data collector, and the display screens at the entrances of all zones are driven by the controller of the corresponding zone; When the controller detects that the location entrance vehicle sensor or each parking space has a signal input from the detector, it will do the “add 1″ operation; when the controller detects that the location exit vehicle detector or the parking space detector is empty, it will do the ” Subtract 1″ operation. The controller calculates the results of the “minus 1” and “plus 1” operations, and displays the vacant parking space information of the location through the display screen connected to it.
