Description

Technical Field

[0001] The invention relates to the technical field of parking lot gate use and bar-breaking alarm design, in particular to an unmanned parking lot bar-breaking alarm system. Background Art

[0002] Parking lot gates are mainly used for parking lots that need to be managed, to restrict the entry of outside vehicles, or to charge vehicles entering and leaving. The gate design itself is a relatively mature product, with functions such as unattended automatic charging.

[0003] The main hardware equipment for closed parking lots currently includes license plate recognition cameras and barriers. The barrier poles are easily hit by cars. As more and more unattended parking lots are built, it is common for the poles to be hit and the perpetrators to be unidentified. Parking lot owners will not only suffer losses from pole damage, but also lose income due to abnormal charging functions. If someone must be on duty, the cost of staff wages will increase.

[0004] For example, a Chinese utility model patent (CN221778352U) discloses a parking lot barrier alarm structure, which records: "The detector on the lever can be used to test the distance between the approaching vehicle and the lever, and it can be displayed on a distance display next to it, which can prompt the driver's current status to avoid unnecessary contact. A warning light is also designed. When necessary, the warning light and the distance sensor are connected through a signal analysis controller. When the distance is too close, the warning light can be turned on." It also records: "In addition, it is very important to detect and report malicious and unintentional barrier violations in a timely manner. Obtaining information at the first time of barrier violation is of great use for finding the responsible person in a timely manner." Technical issues.

[0005] To sum up the above, it can be known that the prior art uses detectors and related components to remind the driver of the distance between the gear lever and the gear lever, and the alarm will be triggered when the gear lever is hit. However, this method has the following technical problems: However, in an unmanned parking lot, when the vehicle causing the accident hits the gear lever and triggers the alarm, then after the relevant personnel arrive at the parking lot, the perpetrator may have fled, and due to the lack of evidence to find the vehicle causing the accident, the difficulty of finding the vehicle causing the accident is increased, and the practicability of the device is not high. For this reason, the present application proposes an unmanned parking lot gear lever violation alarm system to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the invention

[0006] Based on this, it is necessary to provide an unmanned parking lot barrier-breaking alarm system to address the above-mentioned technical problems. The license plate recognition camera module can judge the current state of the gear lever. If an abnormal state is detected, the license plate recognition camera module can immediately send the abnormal state information of the gear lever to the cloud system module through the wireless communication module, and then the cloud system module immediately sends the abnormal information to the parking lot manager. This process is relatively quick and convenient, allowing the parking lot manager to quickly reach the scene to deal with the accident, and when the license plate recognition camera module detects an abnormal state of the gear lever, it can control the environmental camera module to shoot a one-minute on-site video and upload it to the cloud system module for storage, so as to avoid difficulty in confirming and finding the accident vehicle after the accident vehicle leaves the scene, thereby improving the practicality of the device.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The unmanned parking lot barrier-breaking alarm system provided by the present invention can determine the current state of the gear lever through the license plate recognition camera module. If an abnormal state is detected, the license plate recognition camera module can immediately send the abnormal state information of the gear lever to the cloud system module through the wireless communication module, and then the cloud system module immediately sends the abnormal information to the parking lot manager. This process is relatively fast and convenient, and the parking lot manager can quickly reach the scene to deal with the accident.
