"Unattended" Has Become the Development Trend of the Parking Lot Industry, but the Safety Problem st

Almost every family has a car. Today, parking space has become a scarce thing. With the improvement of people's living standards, cars have become a priority for travel. The continuous growth of car ownership has increased a lot of pressure on urban traffic. The following problems are difficult parking and few cars. In order to solve this problem, the concept of "smart parking lot" has been proposed and widely used in various large parking lots. Of course, the continuous growth of car ownership has also driven the development of the parking industry. In the previous parking spaces, special people would control the fluctuation of the stop bar, guide vehicles to enter and charge parking fees. With the increasing scale of urban parking lots and the complexity of service vehicles, the efficiency and reliability of manual management have been difficult to meet the requirements put forward in management. At this time, the use of scientific and technological means to realize the intelligent management of vehicles came into being, and unattended parking lots are rapidly popularized. Advantages: 1) high recognition rate - it realizes the free card collection and charging function of entrance and exit license plate recognition. Combined with vehicle model and color recognition, the automatic recognition accuracy of entrance and exit charges reaches more than 99.5%. 2) Highly integrated - the integrated license plate recognition machine integrates license plate recognition, electromechanical control, soft ground sensing trigger, recognition area setting, network communication and terminal RS485 protocol control, so that one network cable and one power cable can complete the wiring. 3) 100% pass - the intelligent hardware recognition control system of the integrated license plate recognition machine and the intelligent fuzzy error correction matching function of the parking management system software complement each other to ensure 100% pass at the entrance and exit. 4) Fast traffic - the current situation of large traffic flow and frequent and dense vehicles. The vehicle management system with pure license plate recognition and charging can meet the rapid traffic of all vehicles and realize the non-stop admission of vehicles. 5) Unattended - minimize the number of parking lot managers through intelligent entrance operation. The intelligent charging system can automatically charge and reduce the work intensity of parking lot managers. The license plates captured by the exit vehicles and the entry vehicles are directly matched and retrieved, and the displayed exit charging interface realizes rapid charging. When the charging amount is zero, the gate can be opened automatically without charging operation, reducing the workload of toll collectors. 6) diversified charging mode: according to the car park management, we can realize cash payment, WeChat / Alipay mobile payment, payment machine self service payment, central station charging, bar code coupon payment, value payment, official account payment, no sense payment and other charging methods, and support the setting and inquiry of the privilege / free reason. 7) Humanized management mode - when fixed vehicles are not parked in the garage according to the regulations, the system will automatically charge according to the temporary parking charging standard; A car owner can hang three license plates and park any car at the same time, which is convenient for car owners and management. 8) Rigorous management means - capture pictures and license plate numbers of all vehicles in and out. Temporary vehicles are automatically matched in and out, and the temporary parking fee is automatically calculated. In case of free release under special circumstances, there is a selection record of free reasons. 9) Terminal hardware recognition technology - the license plate recognition link in hehao parking lot system is completed by the camera. Similarly, the validity of license plate and the issuance of gate opening command are also completed by the camera, which greatly reduces the dependence on the network and server. Although unattended parking has become the general trend today, there are still potential safety hazards. Whether the parking space induction recognition system can ensure that one car can stop, how to collect the parking invoice, and how to pay if there is no cash... Among them, there is also the most important issue, safety, which is the most concerned point. For facilities and equipment, safety protection, daily inspection and maintenance of equipment, lighting, fire protection, communication, monitoring and other problems in the parking lot, personnel are also required to conduct regular troubleshooting and maintenance, ensure the safe and effective operation of facilities and equipment, and solve emergencies.
