Description

Parking lot file management system

The invention relates to a filing system, in particular to a parking lot filing management system that utilizes a predictive model to analyze the vehicles to which the electronic tag information read is attached, and performs vehicle data filing.

The conventional parking lot management system is based on identifying and comparing the electronic tags of vehicles entering and leaving to open the gate of the parking lot, so that the vehicle can enter and exit the parking lot. When the conventional parking lot management system is applied to a parking lot for specific persons to park their vehicles For example, in the parking lot of a building that only allows residents to park vehicles, the electronic tag information of the residents’ vehicles must be registered in advance to serve as the basis for identification and comparison. Therefore, the administrator of the parking lot must hold a reader to scan the Electronic tags, and manually file the electronic tag information of each vehicle one by one in advance.

However, the number of electronic tags set on each vehicle can be more than one. For example, the electronic tags of the residential parking lot and the school parking lot are set on the vehicle at the same time, resulting in multiple electronic tags on the vehicle. The known parking lot management system reads the information of the electronic tag that is not logged in, resulting in a misjudgment; in addition, the electronic tag of the vehicle may be replaced due to damage caused by external forces. Therefore, the conventional parking lot management system is performing vehicle data filing. At this time, the manager must manually input all the electronic tag information on the vehicle into the database, and when the vehicle is replaced with a new electronic tag, re-scan the electronic tag of the vehicle with a handheld reader, and check the electronic tag of the vehicle. The modification of the electronic tag information in the database of the vehicle requires the administrator to spend a lot of time on data filing, which leads to problems of poor vehicle filing efficiency, waste of manpower time and increased cost.

In view of this, the conventional parking lot management system still needs to be improved.

In order to solve the above-mentioned problems, the purpose of the present invention is to provide a parking lot file management system, which can be applied to manage a parking lot, the parking lot is used for vehicles with only use rights to park, and the electronic tag information of the vehicle is used as the opening gate. conditions, and when the vehicle is archived, it is not necessary to pre-input the electronic tag information of the vehicle into the management system of the parking lot.

Another object of the present invention is to provide a parking lot file management system, which can be applied to manage a plurality of parking lots. When at least two parking lots can be parked by the vehicle with the usage authority, the detected electronic tag information can be synchronized.
