Description
Technical Field
The invention relates to a system and a method for inquiring vehicle searching in a garage, in particular to a system and a method for conveniently inquiring a parking position by a vehicle owner.
Background
More and more households own cars. Therefore, people often drive cars when going out for shopping and handling; for example: go to places such as supermarkets, book buildings, department stores and the like for shopping, go to airports for receiving people, go to outskirts for playing and the like. In these occasions, underground or ground parking garages are provided, so that people can conveniently park the garage when driving out.
However, people also often encounter such things as: when the car is found again after long time of shopping, exhibition and performance, the car can not be found because the parking garage is large in field, and the original parking position can not be remembered. Sometimes the landing from the store is different from the landing from the one entering the store, in which case it is less known where the car is parked. In some cases, it is clear to remember that a particular vehicle is parked near the vehicle, but the particular vehicle is not found when the vehicle is found with the particular vehicle as a reference. The reason is that particular car has been driven away. The parking garage can find the vehicle in a random way, and the time is spent in vain, and the coming and going of the vehicle always affects the driving of other people and is unsafe. When some people find the vehicle, the vehicle can also generate a certain opening angle and contradiction with a driver. It is a common phenomenon to find a car in a large parking garage with almost the same architectural design characteristics.
According to the introduction of a plurality of car visitors of the parking garage: as long as the parking garage has a large area or a plurality of layers, a lot of car finding things can happen every day, and the situation of difficulty in car finding cannot be objectively avoided. When the vehicle is empty, some car visitors can actively help car owners to find cars, but the only basis is the description of the car owners to the own cars, and the car visitors are mainly looking for the cars at four places without more hands for finding the cars. For this reason, some large parking garages are specially provided with posts and personnel for helping car owners to find vehicles. Even some parking garages have purchased the storage battery car that is used for carrying the car owner of looking for specially, and make a round trip to shuttle among the parking garages to make things convenient for the car owner to find the vehicle of oneself. Some parking garages can set some marks on the upright posts and the roadside of the parking garages to remind or help people to memorize the parking positions of the people in order to solve the problem of difficulty in finding the parking garages. While this can improve the problem, it is more of a color than it is indistinguishable. In addition, the mode still requires that the driver must memorize, and brings certain burden to people. If shopping for a long time, watching shows, etc., for example: over 3 hours, the embarrassment of "worldwide" car search is inevitable.
Ground parking garages are usually surrounded by roads, traffic barriers, the height of which is usually not more than 80 cm. After parking in a ground parking garage, people can relatively easily identify and find the original parking position of the people by means of the markers on the ground. Only in special cases, for example: the parking garage has a large area, and surrounding scenery is not noticed after parking, so that the original parking position is not easy to find.
When people park in an underground garage, especially after parking in a double-layer or multi-layer underground garage, the original parking position of the people is not easy to find. The schematic diagram of the underground garage listed in the section of "design of ramp type garage" in the building standard of the underground garage can be known: the structure of each floor of the underground garage is substantially the same. In addition, the building body has a plurality of columns (referred to as "column net" in the building industry), and the distances between the columns are basically equal due to the requirement of the building structure, so that a person seeking the building can feel that the building is positioned in a maze; if the number of layers and positions of the original parking are not particularly memorized, it is also a matter of thinking that the car cannot be found.
"parking position search support device" was invented by panasonic electric industry co. The device judges that the vehicle enters the parking garage through the shooting controller. After the vehicle enters the parking garage, images of the traveling direction of the vehicle are captured using the vehicle-mounted camera and stored at prescribed time intervals. When the vehicle arrives at the parking space and the hand brake is pulled, the shooting is stopped. Thereafter, the photographed image is transmitted to a portable terminal held by the driver. Thus, the driver can view the image through the portable terminal to grasp the parking position of the vehicle. According to the scheme, a camera device needs to be installed on the vehicle, the camera device needs to be connected with a hand brake of the vehicle, signals entering the parking garage need to be sensed, and a communication network and equipment need to be adopted for transmitting image information. To actually solve the problem of difficulty in finding a car with such a solution, many additional conditions are required, and a good cooperation between the user and the parking lot management is required.
The prior art is a search method for a parking position of a global positioning system. The main idea is as follows: the position information of the automobile is transmitted by a Global Positioning System (GPS) transmitter mounted on the automobile, and the parking information transmitted by the GPS transmitter is received and displayed by a GPS receiver in the driver's hand. When the driver leaves the vehicle, the transmitter starts transmitting a signal, which is received by the GPS receiver. Therefore, the problem of difficulty in finding the vehicle can be solved. However, this method requires the driver to carry a set of GPS receiving and transmitting devices, and the driver should carry the device with him, and once he forgets to carry the device, he cannot find the parking position.
The scheme is as follows: when a vehicle drives into a parking garage, a driver takes an Integrated Circuit (IC) card from an administrator, and after the vehicle parks in the parking garage, the driver can swipe the IC card to a nearby card reader, so that the information of the IC card and the position information of the card reader can be transmitted to the system by the card reader for storage. When the driver can not find the parking position, the driver can swipe the IC card again on the inquiry equipment, and the stored position information can be called from the system and displayed to the driver. When leaving the parking garage, the driver returns the IC card to the manager for recycling.
After a series of research and study, the inventor discovers that: at present, the car finding scheme invented by many people at home and abroad has high cost or complicated technology. Some vehicle finding schemes require that a driver is additionally provided with equipment with a high price, and the driver needs to carry an IC card, so that the schemes are complicated, certain burden is brought to the driver, and the scheme is difficult to be widely adopted by the society.
If a simple and easy good method can be found, people can be quickly and conveniently helped to find own vehicles, the time of the people can be saved, and the management level of the parking garage can be improved. Therefore, a garage management system capable of helping people to quickly find the parking position of the own vehicle and automatically inquiring the parking position information needs to be designed, the system is simple and easy to implement, the requirement for complicated equipment can be avoided, extra burden can not be brought to a driver, and even the driver can conveniently, quickly and safely find the parking position only by remembering the number of the vehicle.

Detailed Description
FIG. 1 is a schematic plan view of a parking garage with a camera in an embodiment of the system for searching and querying vehicles in the garage of the present invention; fig. 2 is a schematic structural diagram of an embodiment of the garage vehicle searching query system, and as shown in fig. 1 to 2, one or more specific embodiments of the garage vehicle searching query system of the present invention are as follows:
the garage vehicle searching and inquiring system comprises a shooting device 2, a position identifier, a license plate recognition unit, a computer system, an inquiring terminal and the like which are connected with each other.
The photographing device 2 may be configured by a digital camera or a video camera, and a mobile device. The digital camera or the video camera is arranged on the movable equipment, and the lens of the digital camera or the video camera can be aligned to the license plate on the automobile body at the parking space. Some specific embodiments are: the digital camera or video camera can be arranged on a travelling crane which can reciprocate along the track, the track 1 is arranged on the top of the garage and is positioned in the middle of the travelling lane, cables can be laid on the track, the digital camera or video camera is connected with the cables, power is supplied to the digital camera or video camera, and/or the digital camera or video camera is used for communicating with the license plate recognition unit to transmit shot image data.
In order to adapt to the situation of height change of the parking garage space, a lifting telescopic rod capable of driving the digital camera or the video camera to lift can be arranged on the shooting device 2 if necessary. By the arrangement, the upper and lower positions of the digital camera or the video camera can be adjusted by utilizing the extension and retraction of the lifting telescopic rod under the condition that the parking garage spaces are different in height, and the digital camera or the video camera can be ensured to be always aligned with the license plate for taking a picture.
The license plate recognition unit is provided with an interface for communicating with the digital camera or the video camera and can receive a license plate image shot by the digital camera or the video camera; in addition, the license plate recognition unit is also provided with components or software for license plate information recognition, such as: at present, image-text conversion units are widely adopted on electronic eyes of a traffic management system, and after a license plate recognition unit receives a license plate image shot by a digital camera or a video camera, the image-text conversion units arranged in the license plate recognition unit can convert a license plate number in the license plate image into text information.
The position mark is arranged at any parking space in the parking garage, and can also be arranged at the position corresponding to the corresponding parking space on the track. At the same time, sensors, i.e. position reading devices, which are capable of recognizing these position markers should be correspondingly arranged on the moving parts of the camera. When the moving part of the shooting device moves to a certain parking space, the sensor can acquire shooting position information represented by the corresponding position identification and transmit the shooting position information to the license plate recognition unit, the license plate recognition unit can convert the shooting position information into position parameters, and the position parameters correspond to text information of the license plate number converted by the image-text conversion unit; in addition, when the sensor can acquire the shooting position information represented by the position mark, the shooting device can be controlled to stop at the position for a period of time (for example: 2-10 seconds) or move at a slower speed (for example: 1-10 cm/s), and in such a period of time or at the moving speed, the digital camera or the video camera is further controlled to shoot a license plate image which is clear enough for the image-text conversion unit in the license plate recognition unit to recognize the license plate text information therein.
As previously mentioned, the stationary part is connected to the building structure of the parking garage and is stationary relative to the building structure of the parking garage, and the stationary part of the camera may be a track; in some cases, the device may be a cable winch, and accordingly, the moving part may be movable relative to the stationary part, and the moving part of the camera may be a cable mechanism provided with a digital camera or a video camera, and the cable mechanism is fixedly arranged at a certain position on the cable or the cable. When the cable winch operates, the steel cable and the cable move and drive the cable holding mechanism to move together. Of course, the sensor and the license plate recognition unit capable of collecting the position identification information may be provided on the wire rope, the cable to reciprocate therewith.
If the parking garage is not large, the shooting frequency is not high according to the daily access frequency of the vehicles. In this case, the track or the cable may be arranged in a loop shape, and it is sufficient to use one photographing device for photographing. Under the condition that the parking garage is large in area and the parking areas are distributed more, a plurality of tracks or steel cables and cables can be arranged in a regional direct direction or annular mode, and more than one shooting device can be arranged on each track or steel cable and cable to meet the requirement that the license plate information is collected by the large-area parking garage.
The license plate recognition unit should also have a wireless communication unit in communication with the computer system for sending the recognized text information of the license plate together with the corresponding location parameters to the computer system. In view of the fact that the existing wireless and wired communication technologies are very abundant, only a proper communication mode needs to be selected according to the specific needs of the parking garage, and the invention is not repeated herein.
Correspondingly, the computer system needs to be provided with an interface capable of communicating with the license plate recognition unit, and by utilizing the communication interface, the computer system can communicate with the license plate recognition unit, receive the text information and the shooting position parameters of the license plate image corresponding to the text information, and store the text information and the shooting position parameters of the license plate image corresponding to the text information in a vehicle searching database for subsequent query.
The computer system further can be provided with a component for controlling the shooting device to move and shoot, and a database is arranged to store the text information of the license plate and the shooting position parameter of the corresponding license plate image. The inquiry terminal management module arranged in the computer system can inquire the position information corresponding to the related license plate in the database according to the inquiry command sent by the inquiry terminal.
In fact, the license plate recognition unit can be a shooting device or can be directly arranged in a computer system; the license plate recognition unit can receive the license plate image shot by the shooting device and can provide the converted license plate text information to a database of a computer system for storage.
And the inquiry terminal can be arranged at a proper position at the entrance of the parking garage and can communicate with the computer system. The inquiry terminal is provided with an input key, a touch input device or a handwriting input device, a user can input the position of the license plate to be inquired by using the input devices, the inquiry terminal converts the input of the user into an inquiry command and sends the inquiry command to a computer system connected with the inquiry terminal, so that the computer system can acquire the text information of the license plate and the shooting position parameter of the corresponding license plate image from a database according to the command and send the text information of the license plate and the shooting position parameter of the corresponding license plate image which are sent back by the computer system to the corresponding inquiry terminal, and the inquiry terminal displays the text information of the license plate and the shooting position parameter of the corresponding license plate image to an inquirer in a parking garage position form or adopts a broadcasting device to broadcast the corresponding parking position voice information.
The enquiry terminal can also be arranged in the elevator. Anyone needs to know the position of the automobile and can inquire the position at any time. The inquiry terminal can optimally prompt a route to a parking space according to three elements of garage humanized safety channel information, the position of the current inquiry terminal and parking position information set in the computer while displaying parking space information, and the specific mode can refer to a network map to prompt a driving route.
The inquiry terminal can be provided with one or any combination of a voice input device, a keyboard and a handwriting input device which are necessary for inputting the license plate; and one or any combination of a display screen, a broadcasting device and a printer for displaying the parking position is arranged. For example, if necessary, a small printer may be added to the query terminal, and when the user inputs his own license plate number and finds the parking position information, the query terminal acquires the owner position of the vehicle, the parking position information, the parking garage structure diagram, optimizes the route, and calculates the vehicle finding shortcut, which can be displayed on the query terminal, and also can print the route diagram from the current position of the query terminal to the parking space.
In order to further facilitate car finding, the inquiry terminal can be arranged in the elevator car, so that a driver can complete the car finding operation by utilizing the inquiry terminal in the elevator car when taking the elevator. Of course, a better solution is to combine a computer system, an enquiry terminal and an elevator call system. After the inquiry terminal obtains the license plate number information input by the driver, on one hand, the parking position information is called by the computer system and displayed on the corresponding inquiry terminal; on the other hand, the computer system can send a control command for stopping the floor to the elevator control system according to the floor information given in the parking position information (which is equivalent to the driver pressing a button for reaching the floor in the elevator), and the elevator control system can automatically control the elevator to run to the corresponding floor to stop and open the elevator car.
For a garage or a building with a multi-storey garage and an elevator running, the computer system can be connected with an elevator call control unit, and the inquiry terminal is arranged in an elevator room. Therefore, the inquiry command is input through the inquiry terminal, and the computer system directly controls the elevator calling control unit after retrieving the parking space and parking floor information, thereby achieving the purpose of calling the elevator instead of a car finder. Thus, the driver searching operation can be omitted.
In addition, the system according to the invention can also be installed for a ground parking garage according to the inventive concept. In particular, a ground parking garage is not provided with a ceiling unlike an underground parking garage. But it is possible to provide some frame structures at both ends of the parking garage, such as: the span, length and the like of the frame in the shape of the Chinese character 'men' can be designed according to needs. The rest of the camera can be arranged on the frame structures. The other arrangements may be the same as for the parking garage solution described above.
In reality, anyone remembers the license plate number of the driver, so that the driver can know the parking position of the driver at any time without recording any more information by the system, and can search the past by utilizing the prompting route of the inquiry terminal. Can not be found at any time and can be inquired anywhere. The parking garage is convenient for people, improves the life quality and reduces the potential safety hazard of the parking garage.
Based on the common situation that empty parking spaces are difficult to find in a common parking garage, the invention further provides an empty parking space prompting device which can be arranged at the channel of each layer of the parking garage and is connected with the computer system. The computer system can inquire the database regularly or irregularly, and compare the number of the stored license plate text information and the shooting position parameters of the corresponding license plate images with the actual total number of parking spaces, when a nonzero difference value exists between the two previous data, the fact that the parking spaces exist in the whole parking garage is indicated, the computer system can further determine specific positions of the parking spaces according to the stored license plate text information and the shooting position parameters of the corresponding license plate images, and the information is sent to the empty space prompting device to be displayed, so that a driver seeking the parking spaces can find the positions where the parking can be parked quickly.
The invention can also adopt the following scheme to prompt the empty parking space: in the moving process of the shooting device, as long as the sensor collects shooting position information represented by one position identification, the digital camera or the video camera is started to shoot, when a vehicle is parked on a parking space corresponding to the position identification, the corresponding license plate number can be obtained according to the technical scheme, and otherwise, the license plate number of the corresponding position cannot be obtained. And when the license plate number of the corresponding position cannot be obtained, the position is an empty parking space. Therefore, the information is also transmitted to the computer system like the text information of the license plate and stored in the database of the computer system. In this way, the computer system may not have to: the number of the license plate text information stored in the license plate text information and the number of the shooting position parameters of the corresponding license plate images are compared with the actual total number of the empty parking spaces, so that the specific position information of the empty parking spaces can be directly obtained, and then the corresponding empty parking space prompting devices are controlled to display according to the specific position information of the empty parking spaces, so that a driver who finds the parking spaces can be helped to quickly find the positions where the vehicle can park.
On the basis of the specific embodiments of the various systems described above, it is not difficult to obtain another aspect of the invention: namely a garage vehicle searching and inquiring method based on the system. Since the above technical solutions related to the system have been thoroughly introduced to the related technical contents, the following contents only describe the garage vehicle-searching query method of the present invention in a concise and brief manner:
movably collecting license plate image information and corresponding position parameters of parked vehicles in each parking space in a parking garage;
converting the license plate image information into text information of a license plate;
storing the text information of the license plate and the corresponding position parameters into a database in a one-to-one correspondence manner;
when a command for inquiring the parking space is received, the corresponding position parameter is searched in the database and displayed according to the text information of the license plate carried in the command.
In order to further provide the empty space information, the method may further include:
collecting image information of vehicles which are not parked in each parking space in the parking garage and position parameters corresponding to the image information; and correspondingly storing the corresponding position parameters and the empty parking space identification information into a database according to the image information of the non-parked vehicle. On this basis, can show the position parameter that corresponds with empty parking stall identification information.
For the garage or the building with the multi-layer garage and the elevator running, in order to execute the operation of calling the elevator by using the found vehicle parking position, after searching the corresponding position parameter in the database according to the text information of the license plate carried in the query command, the operation of controlling the elevator calling control unit is further executed by using the position parameter, so that the aim of calling the elevator by replacing a car finder is fulfilled.
