The guiding method forms a complete parking guiding scheme, and can intuitively and efficiently guide a driver to quickly find a parking space through switching of optical signals.
The method further comprises the following steps: and displaying the parking state, acquiring information of distributing the vacant parking spaces after receiving the information that the vehicle drives to the entrance of the parking lot, and controlling the visible light guide component to display a third light color by the guide controller to indicate that a driver drives to park at the specified vacant parking spaces along with entering. When the vehicle detector 1 detects that the designated vacant parking space is occupied by the vehicle, a detection signal is sent to the guidance controller, the guidance controller judges that the parking space is switched to the occupied state and controls the visual light guidance component to switch from displaying the third light color to displaying the second light color to indicate that the parking space is in the occupied state. If the appointed idle parking space is occupied by other vehicles, the color change of the light path can be found and adjusted in time.
The method further comprises the following steps: and the reservation state display is used for acquiring information of distributing the free parking space after receiving the information that the vehicle is ready to drive to the parking lot for parking, and the guide controller controls the visible light guide component to display a fourth light color to indicate that the designated parking route and the free parking space are reserved. And after receiving the information that the specified vehicle has driven to the entrance of the parking lot, the guide controller controls the visible light guide component to display a third light color to indicate that the driver drives to park at the specified vacant parking space along with entering. Or sending a detection signal to the guidance controller until the vehicle detector 1 detects that the designated free parking space is occupied by the vehicle, and the guidance controller judges that the parking space is switched to the occupied state and controls the visual light guidance component to switch from displaying the fourth light color to displaying the second light color to indicate that the parking space is in the occupied state. The driver can receive the reserved parking space information and the fourth light color information in advance, and the vehicle can be guided to the parking space by contrasting the fourth light color information when driving to the entrance of the parking lot, so that the whole parking process can be finished automatically and continuously.
The first color is green, the second color is red, the third color is yellow, and the fourth color is blue.
In a specific embodiment, the first color is an arbitrary color, the second color is a non-light-emitting color, and the third color is a flashing color. Alternatively, the first light color is any light color and the second light color is no light color, i.e. the prompt or guide can be completed by turning on or off the light path. The adoption of the light color can be better accepted by the public, and is suitable for popularization and application.
Specifically, the indoor parking lot is surrounded by wall 3, and the top is ceiling 4, when waiting to enter vehicle 6 and will go into the parking stall from the parking lot entry, visual guide 2 of sidelight of visual optic fibre or LED lamp area form extends to every parking stall from the entry, and visual optic fibre or LED lamp area that upper portion set up can be fixed with the mode of bearing in a hanging manner. For large parking lots, additional bundling or aggregation devices are required to accommodate the narrow entrance to the parking lot. According to the actual requirement, the light sent into the collecting device can be continuous color light transmitted or emitted by an optical fiber (or an LED lamp strip) or high-frequency digital optical communication pulse. This scheme has good infrastructure, need not to do big change to current parking area, and is with low costs.
Once the vehicle enters the parking lot, the driver can see which optical fibers on the top of the head are red and which optical fibers are green, the driver can move along the optical fibers which are flickered in a special color/special mode designated by the system, and can also follow any one of the green optical fibers, so that the vehicle can be easily parked in an idle parking space, the trouble of finding the parking space around in a strange environment is avoided, and the vehicle 7 which has entered the parking lot is prevented from being quickly parked. The scheme is energy-saving, low in cost, high in visualization degree and good in continuous guiding effect. In the practical application environment, the occasion with higher requirement on brightness can adopt the colorful LED lamp strip to replace the sidelight visible optical fiber. In addition, convenient information prompt boards and facility signboards 5, such as indication signs of escalators, vertical ladders, stairs, toilets, emergency exits and the like, which are adjacent to the visual light guide assembly are arranged at the entrance and the lane of the parking lot and used for informing drivers of which parking spaces in the parking lot are closer to the facilities, so that the drivers can conveniently select the parking spaces near the destination to park nearby, and the drivers can more quickly arrive at the place where the drivers want to go. The scheme gives consideration to the indication function of other common auxiliary guide signs and is more humanized in design.
Furthermore, for people with color weakness and color blindness, the system can choose to adopt a monochromatic light working mode for guiding. The specific implementation method comprises the following steps: the parking space indicating lamp is turned off under the condition that a vehicle is in the parking space, and the optical fiber (or the LED lamp strip) does not emit light to represent that the vehicle is in the parking space; the parking space indicating lamp is turned on under the condition that no vehicle is available, and the optical fiber (or the LED lamp strip) emits light to represent that no vehicle is available in the parking space. The parking space can be found only by driving along the luminous optical fiber (or the LED lamp strip).
The working process of the whole system is as follows: when a vehicle is parked in a parking space, the vehicle detector 1 sends a red light signal or red light communication pulse, the signal is directly displayed on the shell of the vehicle detector 1 right above the parking space, and meanwhile, the signal is guided to the entrance of the parking space through the sidelight visible optical fiber (or the LED lamp strip), so that a driver of an entering vehicle can know that the parking space is occupied. When no vehicle exists in the parking space, the vehicle detector sends out a green light signal or a green light communication pulse, the signal is displayed on the shell of the vehicle detector, and meanwhile, the signal is guided to the entrance of the parking lot by the side light visible optical fiber (or the LED lamp strip), so that a driver of an entering vehicle knows that the parking space is free, and can drive the vehicle to park and enter the parking space along the green light path track. The system can enable a driver to know the parking space occupation state in the parking lot before entering the parking lot, and to make a clear of the driving route, so that the blind psychological state of parking in the parking lot is eliminated, and the guiding accuracy is improved.
On a driving road from the entrance of the parking lot to the designated vacant parking space, the green light path is changed into a blue or flashing state to distinguish the green light paths of other vacant parking spaces. The blue or flashing state can also avoid the conflict situation that the rear vehicle cannot stop to the expected idle parking space due to the fact that different drivers select the same light path and do not reach the parking space in the process of driving to the parking lot and the signal change is not timely.
When the parking space is an outdoor parking space, referring to fig. 3, the vehicle detector 1 is installed in the center of the ground of each parking space, the side light visual guide part 2 adopts an LED lamp strip, the vehicle detector 1 and the side light visual guide part 2 are embedded into the ground by using a glass cover plate or transparent concrete and are located right below a vehicle driving route, the LED lamp strip continues from an entrance of the parking space to each parking space and is in signal connection with a parking space indicator lamp, namely the LED lamp strips are respectively and independently laid from each parking space to the entrance of the parking space and are finally collected to the entrance of the parking space and are uniformly arranged in a row to form a plurality of light paths. The luminous color of the LED lamp strip indicates the state information of the parking space, and meanwhile, the track of the LED lamp strip is a specific traveling route of the vehicle entering the parking space. The LED lamp strip displays whether vehicles exist in corresponding parking places through different colors. Therefore, the travelling route from the entrance of the parking lot to each parking space can be clearly indicated, and the effect of rapid guidance is achieved.
Further, the vehicle detector 1 adopts a ground induction coil type metal detection sensor, outputs a corresponding parking space state in a switching value mode, and the metal detection sensor is in telecommunication connection with the LED lamp strip. The system is mainly suitable for outdoor parking lots, and ensures real-time detection of the brightness and the vehicle state of the guiding device.
Specifically, the outdoor parking lot is also surrounded by the wall 3, but has no ceiling, so that the LED strip is laid from the entrance of the parking lot to each parking space in a manner of being embedded in the ground. The vehicle detector 1 may further include a display beside the parking space or the parking space indicator light, and is configured to display the parking space state together with the LED light strip. The driver guides according to the green LED lamp area on ground to find the idle parking stall fast and parks, has improved the efficiency of idle parking stall location and parking.
