Description

Technical Field

[0001] The utility model relates to the technical field of intelligent garages, and in particular to a parking guidance system for an intelligent garage based on the Internet of Things. Background Art

[0002] Underground garages (underground parking lots) refer to buildings built underground for parking various sizes of motor vehicles. The construction of underground garages can make full use of underground space for parking, which is of great significance for alleviating urban road congestion. Underground garages are large in area and are usually divided into multiple areas, where the lanes are intricate, especially in public garages. Most users are not familiar with the lanes in the garage, and it is more difficult to find an empty parking space when parking, resulting in low parking efficiency.

[0003] In traditional underground garages, parking area signs are usually pasted or hung above the driveway or on a wall column on one side, and users look for parking spaces based on the signs. Since underground garages often have dim optical fibers, users should not be distracted too much by looking at the signs while driving. Therefore, this method has a low guiding effect on users when parking and is not very helpful for users to find vacant parking spaces for parking.

[0004] In this regard, there are related solutions in the prior art, which use lighting guidance to guide parking. By installing lamps above the driving lane, the light is used to guide the user to the vacant parking space. Patent document ZL2021231500413 discloses a lighting guidance device and system for a garage, including a first lamp unit arranged in the parking space and a second lamp unit arranged on the lane. By controlling the two lamp units to turn on and light up, the parking space and the parking route are illuminated to achieve parking guidance. This parking guidance method is suitable for situations such as communities with fixed parking spaces. It is not very effective for parking guidance in public parking lots, especially when multiple vehicles enter in a short period of time. It is not conducive to parking guidance for the following vehicles. Therefore, it is still necessary to improve the parking guidance technology and develop a parking guidance method suitable for public underground garages. Summary of the invention

[0005] In order to better solve the above problems, the utility model implements a parking guidance system for a smart garage based on the Internet of Things, which monitors parking space status based on a camera and provides parking guidance based on multiple sets of colored lights.

[0016] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0017] Figure 1 This is a structural schematic diagram of a parking guidance system for a smart garage based on the Internet of Things according to an embodiment of the utility model. DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited to the basic implementation disclosed below.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0020] like Figure 1 As shown, a parking guidance system for a smart garage based on the Internet of Things according to an embodiment of the utility model includes a host computer and a parking space monitoring device, a guide light device, and a garage gate electrically connected to the host computer respectively.

[0021] Among them, the parking space monitoring device includes multiple cameras, which are respectively set in multiple parking areas in the garage, and are used to collect images of each parking space in the garage; each camera is electrically connected to the host computer, and is used to send the collected parking space image to the host computer, so that the host computer can identify it according to the parking space image and obtain the occupancy information of each parking space. Here, each camera can collect images of multiple parking spaces, and it can be ensured that each parking space is within the coverage of at least one camera. In practical applications, if there is already a video surveillance system in the garage, the parking space monitoring device can use multiple cameras in the video surveillance system. Of course, if the number of cameras in the video surveillance system is small and cannot accurately cover each parking space, multiple cameras can be added so that the image of each parking space can be collected.

[0022] The guide light device includes at least two groups of colored light assemblies and a plurality of lamp drivers, each group of colored light assemblies includes a plurality of colored lights of one color, and is arranged above the driving lane in the garage; specifically, the plurality of groups of colored light assemblies light up lights of different colors respectively, and each group of colored light assemblies includes a plurality of colored lights that light up the same color, and the plurality of colored lights are arranged on the wall above the driving lane at intervals, that is, at least two colored light circuits are arranged above the driving lane. In this embodiment, the colored lights are arranged to guide users to park, and the colored lights are not required to provide lighting functions, so conventional low-power LED colored lights can be used. Of course, small LED light strings or light strips can also be used. Each lamp driver is electrically connected to the host computer and is also electrically connected to one or more colored lights, and is used to receive a lighting instruction sent by the host computer, and execute a corresponding action in response to the lighting instruction to drive the corresponding colored lights to light up.

[0023] The garage gate includes a gate machine and a gate rod, which are arranged at the entrance of the garage. The gate rod is rotatably connected to the chassis of the gate machine. A gate controller and a gate rod driving mechanism are arranged in the chassis of the gate machine. A license plate recognizer, a display screen, and a voice announcer are arranged on the chassis of the gate machine. The gate controller is electrically connected to the host computer, the gate rod driving mechanism, the license plate recognizer, the display screen, and the voice announcer respectively. When there is an approaching vehicle at the garage entrance, the license plate recognizer scans and recognizes the license plate information of the vehicle at the garage entrance and sends it to the gate controller. The gate controller sends the license plate information to the host computer, receives the vacant parking space information and guide light information fed back by the host computer, and sends an action instruction to the gate rod driving mechanism, so that the gate rod driving mechanism The mechanism is started to drive the gate rod to rotate upward and open the garage; at the same time, the gate controller also sends a display instruction to display the vacant parking space information and the guide light information to the display screen, and sends a play instruction to broadcast the guide light information to the voice announcer, wherein the vacant parking space information can display information such as the area where the parking space is located and the parking space number, and the guide light information is the light color corresponding to the vacant parking space. For example, the display screen displays "Please follow the red light instructions and go to parking space A1001"; accordingly, the voice announcer can play "Please follow the red light instructions and go to parking space A1001". When entering the garage, the user can obtain the parking path and parking space guidance through the information displayed on the display screen and the voice played by the voice announcer.

[0024] The host computer receives the parking space images sent by each camera, uses the more mature image recognition technology in the existing technology to identify whether the parking space is occupied, and counts the information of the vacant parking spaces. After the host computer receives the license plate information sent by the gate controller, it selects an vacant parking space from multiple vacant parking spaces. Specifically, it can select an vacant parking space that is closer to the garage entrance where the gate is located; at the same time, the host computer selects a group of colored lights from multiple groups of colored lights, determines the parking path from the corresponding garage entrance to the parking space, selects the lamp driver corresponding to the colored lights on the parking path, and sends a lighting instruction to the selected lamp driver to light up the colored lights on the parking path, which plays a role in guiding users to park. The host computer feeds back the information of the selected vacant parking space and the information of the selected colored lights to the gate controller, so that the garage gate can display and voice broadcast, making it convenient for users to obtain parking guidance information.

[0025] In an optional implementation, the host computer selects colored lights in a cycle according to a set order and controls the lighting, so that when multiple vehicles enter in a short period of time, different colored colored lights can be used to guide users to park differently, ensuring the same guiding effect on the following vehicles. In addition, the host computer can also send a light-off instruction to the lamp driver after a set time, or identify the vehicle position based on the received parking space image, and send a light-off instruction to the lamp driver corresponding to the colored lights on the path that the vehicle has traveled. Of course, a timed light-off mode can also be set in the lamp driver.

[0026] Optionally, in the parking area of ​​the garage, the interval between the colored lights can be the width of a parking space, so that there is a colored light in front of each parking space, that is, each parking space corresponds to a colored light. When the host computer selects an empty parking space, the colored lights between the colored lights in front of the empty parking space and the garage entrance can be selected to light up, forming a colored light guide path from the garage entrance to the empty parking space.

[0027] Correspondingly, at the driving lane of the non-parking area of ​​the garage, each lamp driver can be electrically connected to multiple colored lights; at the driving lane of the parking area, each lamp driver is electrically connected to one colored light. That is, in the parking area, each parking space corresponds to a colored light, and each colored light is associated with a lamp driver, so as to facilitate the precise guidance of each parking space; in the non-parking area, the lamp driver is associated with multiple colored lights, so as to facilitate the control of multiple colored lights to light up synchronously. Here, the lamp driver may include a micro control unit, a relay unit and a wired / wireless communication unit. The micro control unit is connected to the host computer through the wired / wireless communication unit, and sends an action instruction to the relay unit after receiving the lighting instruction. The relay unit is connected to the power supply line of the colored light. The relay unit responds to the action instruction sent by the micro control unit to perform corresponding actions to drive the colored light to light up or turn off.

[0028] Optionally, the parking guidance system includes a lighting device, which includes a plurality of lighting lamps, which are respectively arranged at each parking space in the garage. Each lighting lamp is equipped with a lamp driver or a lighting switch. When the host computer selects an empty parking space, the lighting lamp at the empty parking space can also be controlled to light up, so as to illuminate the parking space and facilitate the user to park. Of course, if the lighting system in the garage can make each parking space have sufficient brightness, it is not necessary to set a lighting lamp at each parking space.

[0029] In the parking guidance system for a smart garage based on the Internet of Things in the embodiment of the utility model, a parking guidance method combining parking space status monitoring based on a camera and parking guidance based on multiple sets of colored lights is proposed. The main technical idea is to form a system architecture by setting hardware devices such as cameras, colored lights, lamp drivers, gate machines, license plate recognizers, display screens, voice announcers, and host computers. Each hardware device in the system can adopt devices or electrical components with corresponding functions in the prior art, as well as relevant pin port connection methods in the prior art; the control logic executed by the host computer and the gate controller in the system can adopt relatively mature related control strategies in the prior art.

[0030] In actual application scenarios, the system can also be combined with the existing video surveillance system and security barriers in the garage, and the actual application of the system can be realized by modifying the existing equipment. For example, in the case where the garage security barrier is integrated with a display and a voice announcer, the function of the garage barrier of this embodiment can be realized by adding or rewriting the barrier controller. For another example, the parking space monitoring device of this embodiment uses mechanical vision instead of an inductive parking space detection device. It can realize the function of the parking space monitoring device of this embodiment based on the existing video surveillance system of the garage and adding a camera. The system application can be completed by modifying a small amount of new equipment, and the cost is relatively low; moreover, the host computer can also be connected to the garage video surveillance system for communication, and is used to send the received parking space image to the garage video surveillance system, which is stored by the garage video surveillance system, which can improve the perfection of video surveillance.

[0031] Furthermore, in actual application scenarios, the parking guidance system may also include other components or electronic devices for realizing the actual installation and application of the parking guidance system. For example, it may also include a communication device, which may include multiple communication nodes to facilitate communication between the host computer and cameras and lamp drivers in multiple areas of the garage.

[0032] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
