The parking lot computer charging management system is a general term for the modern parking lot vehicle charging and equipment automation management. It is a high-tech mechatronics product that puts the parking lot under computer management.
With the progress and development of society, people’s lifestyles have undergone profound changes, and urban traffic congestion is one of the phenomena. The traffic congestion and even chaos caused by the increase in transportation in the city brings great inconvenience to people’s lives. This inconvenience forces people to find high-tech and effective means to solve this inconvenience. The intelligent parking lot is a high-tech product that meets the needs of this era. It can not only effectively solve the traffic chaos caused by random parking, but also promote the regular construction of transportation facilities, and at the same time, it can also reduce the loss of car owners as much as possible. Worries about the theft of the car. In addition, in terms of technology, its high technology matches other existing intelligent systems, has good openness, and is easy to combine with other intelligent systems to form a more powerful integrated system, which is compatible with various integrated methods of advanced management.
Parking management is aimed at the management needs of building a safe and civilized community. It aims at the intelligent management of parking lots in the property community. It focuses on purchasing fixed card parking users in the community to achieve convenient, fast and safe entry and exit of parking users. The management of the property company is scientific and efficient, and the purpose of serving high-quality and civilized. It will play an important role in improving the management level and comprehensive service level of the property management company.
Mulan parking lot management system is a multimedia comprehensive vehicle charging management system that uses non-contact radio frequency cards as vehicle entry and exit parking vouchers and vehicle image comparison management as the core. The system combines advanced 2.4G radio frequency card identification technology with high-speed video image storage and comparison, and through computer image processing, it conducts comprehensive management of the charging, security and management of vehicles entering and leaving the parking lot.
In the non-contact 2.4G radio frequency card parking lot management system, when the owner of the fixed card enters and exits the parking lot, the card reader automatically reads the card and judges the validity of the card, and the camera records the image of the car. For a valid 2.4G radio frequency card, the gate lever of the automatic barrier is raised and released and the corresponding data is stored in the database. If it is an invalid 2.4G radio frequency card or the images of vehicles entering and exiting the venue are different, they will not be released.
For car owners who temporarily parked, after the vehicle detector detects the car, the security will give the car owner a radio frequency card, camera and release. When leaving the field, read the card at the exit control machine and pay the parking fee. At the same time, compare the images of the vehicle. If there is no abnormal situation, the barrier will be raised and let go.
At the same time, the parking lot management system has powerful data processing functions, which can complete the setting of various parameters of the toll management system, data collection and statistics, report the loss of lost cards, and print effective statistical reports.
system design
Design ideas:
Based on the above design principles and our understanding of the owner’s needs, we provide the following configurations:
The entrance and exit are equipped with a 2.4G radio frequency card reader, using Mulan’s ML-T80 radio frequency card. The communication distance of the card is 2-80M. The entire system is equipped with an image comparison system to realize the safety management of temporary vehicles. The toll booth of the temporary card is set on the left side of the temporary car’s exit/entry, so that both the temporary car and the owner’s car can be controlled at the same time. A waste of financial resources can be said to kill three birds with one stone.
Owner’s car:
Owners can choose a fixed card according to their needs
The fixed card can set the effective time for vehicles to enter and exit the parking lot by month or days. After the fixed period expires, the entry authority must be re-authorized, otherwise the card will lose the right to enter and exit.
The fixed card needs to deposit a certain amount in advance, the system will automatically deduct the money according to the number of entrances and exits and the time, and the stored-value card can be recharged at any time
If the amount of the stored-value card is insufficient or the monthly card expires during the entry and exit process, the system will use voice prompts to guide the owner to complete the corresponding operations.
Temporary car:
After the entering vehicle is confirmed by the system, the security guard gives a temporary card, and the card reader automatically reads the card information, and starts the image comparison system to complete the shooting of the license plate number and the vehicle image. After the camera, the barrier starts automatically. The car is allowed to enter the venue.
Performance analysis: There is no doubt that this configuration can meet the requirements of the owner no matter from which point of view, it also reserves considerable space for the expansion of the system from the actual situation;
System security: As far as the above configuration is concerned, the security of the entire system is impeccable. The corresponding principle of one card and one car in the image comparison system can guarantee: the same 2.4G radio frequency card can only be carried in and out of the parking with the same car field.
Scalability of the system: Due to the use of 2.4G radio frequency card, the expandability of the system is partially improved. The read and write performance of the 2.4G radio frequency card determines that the owner can apply the card to other occasions in community management, such as access control , Club consumption, etc., it is foreseeable that the 2.4G radio frequency card will bring great convenience and return to owners and managers for a long time in the future, and gradually realize the true all-in-one card without being eliminated by the market. .
2.4G radio frequency card for parking lot
Fixed card
It is a 2.4G radio frequency card authorized and issued by the parking lot management system. It is issued by the 2.4G radio frequency card issuance system after the long-term use of the designated parking lot owner applies and is reviewed and approved by the management department. The card pays the parking lot fee monthly or within a certain period, and enjoys the convenience of parking in the parking lot within the valid time period.
temporary card
It is also a 2.4G radio frequency card authorized by the parking lot management system. It is a temporary or invalid card owner’s entry and exit certificate when parking in the parking lot. The parking fee incurred by the car owner in the parking lot must be paid in cash and the card should be returned when leaving the field. According to the different types of vehicles entering the field, they are divided into three categories: A, B, and C.
