Detailed Description
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
In the description of the present invention, unless otherwise specified and limited, it is to be noted that the term "connected" is to be interpreted broadly, and may be, for example, a mechanical connection or an electrical connection, or a communication between two elements, or may be a direct connection or an indirect connection through an intermediate medium, and a specific meaning of the term may be understood by those skilled in the art according to specific situations.
Referring to fig. 1, a block diagram of an embodiment of the parking lock control system based on networking data of the internet of things is shown. The system comprises a parking lot control system, a parking lot navigation and positioning system and parking lot locks correspondingly arranged aiming at each parking lot in the parking lot, wherein the parking lot control system collects license plate numbers of vehicles driving into the parking lot, searches corresponding parking lot numbers according to the collected license plate numbers and sends the searched parking lot numbers to the parking lot navigation and positioning system; referring to fig. 2, the parking lot navigation and positioning system includes detection units respectively disposed at an entrance end and an exit end of each road section in a parking lot, each detection unit includes a controller, an infrared sensor and a networking module, each controller is connected to its corresponding infrared sensor and networking module, when a vehicle passes through the corresponding infrared sensor, the infrared sensor is triggered to output a signal, an internet of things is established between the controllers through the networking module, the infrared sensors outputting the signal are shared, the position of the vehicle is positioned according to the position information of the infrared sensor outputting the signal, for each road section, the controllers at the entrance end and the exit end of the road section are connected to parking space locks of parking spaces on both sides of the road section, when the infrared sensor on the road section where the parking space corresponding to the vehicle is located outputs the signal, the vehicle is indicated to the road section where the parking space is located, and the controller on the road section controls the parking spot lock of the corresponding parking spot on the road section to be opened according to the parking spot number of the vehicle.
According to the invention, the detection units are respectively arranged at the inlet end and the outlet end of each road section in the parking lot to position the position of the vehicle, and when the vehicle runs to the road section where the parking space is located, the parking space lock of the corresponding parking space on the road section is controlled to be opened, so that the situation that a user needs to manually operate when opening the parking space lock can be avoided, and the convenience of opening the parking space lock is improved.
Although the position of the vehicle can be located by arranging the detection units at the entrance end and the exit end of each road section, the parking space lock of the vehicle can be controlled to be opened after the vehicle runs to the road section where the parking space is located, if the internet of things is established only for opening the parking space lock, the cost is very high. In fact, the purpose of installing the parking spot lock by the owner is to avoid that the external vehicle parks in a messy way and occupies a parking spot, and when the external vehicle drives into a strange parking lot, it also takes a long time to find the parking spot, so the parking lot navigation positioning system can also provide a navigation function for the vehicle.
The parking lot navigation and positioning system divides a parking lot path with a tree structure (a road section connected with an entrance and an exit of a parking garage is a root road section) into a plurality of road sections, and for each road section, only two ports of an entrance end and an exit end are provided, and at least one port is connected with the plurality of road sections. According to the invention, the parking lot path is constructed into the tree structure, and the tree structure is improved, so that each road section in the tree structure is only provided with two ports, and at least one port is connected with a plurality of road sections, so that the position of a vehicle can be accurately positioned, as shown in a figure 3, the road section 1 and the road section 6 are the same road section in the traditional tree structure, and the specific position of the vehicle on the road section cannot be accurately positioned at the moment, and the road section 1 and the road section 6 are different road sections in the improved tree structure of the system, so that the vehicle can be accurately positioned on the road section 1 or the road section 6 at the moment; each road section in the system has only one upper road section, for example, the upper road section of the road sections 2, 3 and 6 in fig. 2 is road section 1, and the upper road section of the road sections 4 and 5 is road section 3. According to the invention, the parking lot path is constructed into a tree structure, each road section has only one previous road section, and navigation is carried out based on the division, so that each infrared sensor has only one previous infrared sensor, the condition that a plurality of previous infrared sensors exist is not considered, and the navigation accuracy can be ensured.
For each road section, as shown in fig. 2, a display connected to a controller at an exit end of the road section is disposed at a front end of the exit end, for each controller, when a corresponding vehicle passes through an infrared sensor corresponding to the controller, the infrared sensor is triggered to output a signal, the infrared sensor transmits the signal to the controller, the controller receives the signal provided by the infrared sensor, generates corresponding detection information, and transmits the generated detection information to other controllers through a networking module of the controller, wherein the detection information includes identification information of the infrared sensor that detected the signal and time information when the signal is detected. According to the invention, the controllers, the infrared sensors and the networking module are arranged at the access ports of each road section, the Internet of things is established among the controllers through the networking module, and the identification information of the infrared sensors is sent to the Internet of things when the vehicles pass through the corresponding infrared sensors, so that each controller can obtain the identification information of the corresponding infrared sensor, and a data basis can be provided for the accurate positioning of each subsequent vehicle.
The parking lot control system collects license plates of vehicles driving into a parking lot, compares the collected license plates with locally stored license plates of owners, if the collected license plates are the same as the locally stored license plates of the owners, searches corresponding parking space numbers according to the collected license plates, sends the searched parking space numbers to a controller at an entrance/exit of the parking lot, and if the collected license plates are not the same as the locally stored license plates of the owners, allocates temporary parking space numbers to the vehicles and sends the temporary parking space numbers to the controller at the entrance/exit of the parking lot. After receiving signals provided by the infrared sensors of the controllers at the entrance and exit of the parking lot, the controllers plan driving routes from the entrance and exit of the parking lot to the vehicle parking spaces according to the parking lot routes and transmit the driving routes of the vehicle and the corresponding parking space numbers to other controllers through networking modules of the controllers, and the driving routes comprise the infrared sensors on all road sections through which the vehicle is about to pass and identification information of the infrared sensors. In addition, each controller locally stores an infrared sensor topological graph, the infrared sensor topological graph comprises the position relation among the infrared sensors in the parking lot and identification information of the infrared sensors, for each road section, the infrared sensor at the inlet end is the last infrared sensor at the outlet end, and the last infrared sensor of the infrared sensor at the inlet end is the infrared sensor at the outlet end of the road section at the previous stage connected with the inlet end of the road section. Since each road section has only one previous road section in the tree structure, each infrared sensor in the infrared sensor topological graph has only one previous infrared sensor. According to the invention, the infrared sensor topological graph is locally stored in each controller, so that a data base can be provided for accurate positioning of subsequent vehicles.
Although the vehicle gets into the parking area, each infrared sensor after detecting the signal, its corresponding controller all can send the identification information who detects the infrared sensor of signal to each other controller in the thing networking, the vehicle that gets into the parking area usually can not only be one, how to distinguish infrared sensor because which car passes through the trigger output signal to pinpoint each vehicle, become the key that realizes accurate navigation. For this purpose, for each controller, as shown in fig. 4, it includes a driving route determining unit, a driving route processing unit, a driving route re-planning unit, and a driving route updating unit.
The driving route determining unit is used for determining the driving route of the vehicle triggering the current infrared sensor to output signals according to the infrared sensor topological graph, the driving routes obtained in sequence, the identification information of the current infrared sensor in the current detection information and the time information after the current detection information is obtained. Specifically, the driving route determining unit is configured to, after obtaining current detection information, first determine, according to identification information of a current infrared sensor in the current detection information, identification information of a current previous infrared sensor of the current infrared sensor in the infrared sensor topological graph, sequentially determine whether the identification information of the current previous infrared sensor is the same as identification information of an infrared sensor that is recently marked as having passed in each driving route obtained in sequence, if so, use a corresponding driving route as a suspected driving route of a vehicle that triggers an output signal of the current infrared sensor, and determine the number of the suspected driving routes of the vehicle:
and if a suspected driving route exists, determining the suspected driving route as the driving route of the vehicle triggering the output signal of the current infrared sensor. Although the system can navigate the vehicle, the vehicle may miss the best opportunity for navigation and steering and enter the wrong road section, if backing up at the garage at the time, a great safety hazard may exist, and when another vehicle is immediately behind the vehicle, the possibility of backing up does not exist. If the situation that the vehicle enters the wrong road section is not considered, the vehicle cannot find the parking space allocated to the vehicle after entering the wrong road section, and the navigation accuracy of other vehicles is influenced. For this reason, the present invention does not directly compare the identification information of the current infrared sensor with the identification information of the next infrared sensor in each route, which is the infrared sensor that has been most recently marked as having passed, when the vehicle is located, because once the vehicle enters the wrong road segment, the current infrared sensor will not belong to the infrared sensor in the route of the vehicle, and thus the determined route matching the current infrared sensor will be incorrect. Because the infrared sensor which is marked as passed in the driving route most recently is fixed, and the current previous infrared sensor of the current infrared sensor in the infrared sensor topological graph is also fixed and unique, the invention firstly determines the current previous infrared sensor of the current infrared sensor in the infrared sensor topological graph, and compares the current previous infrared sensor with the infrared sensors which are marked as passed in the driving routes obtained successively, thereby determining the driving route of the vehicle which triggers the output signal of the current infrared sensor, and even after the vehicle enters the wrong road section, the driving route of the vehicle which triggers the output signal of the current infrared sensor can be accurately found.
There may be a situation in the parking lot where two vehicles are traveling immediately ahead, as shown in fig. 5, vehicle 1 and vehicle 2 are traveling immediately ahead, when the vehicle 1 passes the infrared sensor 2-1, the vehicle 2 passes the infrared sensor 3-1, the infrared sensor 2-1 and the infrared sensor 3-1 are both the infrared sensor 1-2 on the last infrared sensor in the infrared sensor topological graph, according to the infrared sensor 1-2, two suspected driving routes can be determined, at the moment, the controller can not determine whether the vehicle 1 or the vehicle 2 triggers the infrared sensor 2-1 to output signals, since the vehicle 1 is located in front of the vehicle 2, the time when the vehicle 1 triggers the output signal of the infrared sensor should be earlier than the time when the vehicle 2 triggers the output signal of the infrared sensor, and the time for establishing the corresponding driving route of the vehicle 1 is earlier than the time for establishing the corresponding driving route of the vehicle 2.
For this reason, if there are two suspected driving routes, it indicates that there is a case where two vehicles are traveling immediately ahead, at this time, first, reference detection information (which may include detection information triggered by other vehicles other than the two vehicles) obtained in a front and back preset time period is determined, and a reference previous infrared sensor of a reference infrared sensor in each reference detection information in the infrared sensor topological graph is determined, and it is determined whether identification information of each reference previous infrared sensor is the same as identification information of an infrared sensor that is marked as having passed recently in the two suspected driving routes, if so, the time for detecting a signal by the reference infrared sensor and the current infrared sensor is compared: and if the time when the current infrared sensor detects the signal is earlier than the time when the reference infrared sensor detects the signal, determining a suspected driving route obtained earlier in the two suspected driving routes as the driving route of the vehicle triggering the signal output by the current infrared sensor, and if the time when the current infrared sensor detects the signal is later than the time when the reference infrared sensor detects the signal, determining a suspected driving route obtained later in the two suspected driving routes as the driving route of the vehicle triggering the signal output by the current infrared sensor. According to the method, the time when the two vehicles pass through the corresponding infrared sensors to trigger the output signals of the corresponding infrared sensors is obtained aiming at the condition that the two vehicles are suspected to run immediately ahead, and the running route of the vehicle triggering the output signals of the corresponding infrared sensors is determined according to the morning and evening of the time and the establishment of the two suspected running routes, so that the running route of the vehicle triggering the output signals of the current infrared sensors can be accurately found out even if the two vehicles run immediately ahead.
The driving route processing unit is used for judging whether a vehicle triggering the current infrared sensor to output signals moves forwards on the driving route according to the identification information of the current infrared sensor and the determined driving route, and if so, marking the next infrared sensor of the infrared sensor which is recently marked as passed in the determined driving route as passed. Specifically, the driving route processing unit is configured to determine whether the current infrared sensor is a next infrared sensor of an infrared sensor that is most recently marked as having passed in the determined driving route, if so, it indicates that the vehicle that triggered the output signal of the current infrared sensor is traveling on the driving route thereof, and mark the next infrared sensor of the infrared sensor that is most recently marked as having passed in the determined driving route as having passed, otherwise, it indicates that the vehicle that triggered the output signal of the current infrared sensor is not traveling on the driving route thereof. When the vehicle moves forwards on the driving route, the next infrared sensor of the infrared sensor which is most recently marked as passed in the determined driving route is marked as passed, so that the position of the vehicle can be conveniently positioned through the driving route of the vehicle.
And the driving route re-planning unit is used for re-planning the driving route of the vehicle if the current infrared sensor corresponds to the controller when judging that the vehicle triggering the output signal of the current infrared sensor does not move ahead on the driving route, and transmitting the re-planned driving route to other controllers through the networking module. Specifically, the driving route replanning unit is configured to, when it is determined that the vehicle triggering the output signal of the current infrared sensor does not move forward on the driving route of the vehicle, if the current infrared sensor corresponds to the controller, take the current infrared sensor as a start point infrared sensor, replan the driving route from the start point infrared sensor to an end point infrared sensor in the determined driving route according to the parking lot path, and transmit the replanned driving route to each of the other controllers through the networking module. When the vehicle does not move forwards on the driving route, the driving route is re-planned, and the accurate navigation of the vehicle can be realized even if the vehicle enters a wrong road section.
The driving route updating unit is used for updating the driving route after the driving route is re-planned or the re-planned driving route is received. Specifically, the driving route updating unit is configured to mark the determined driving route as invalid when it is determined that the vehicle triggering the output signal of the current infrared sensor does not move forward on the driving route, determine a previous infrared sensor of the infrared sensor topology map at a starting point in the re-planned driving route after re-planning the driving route or receiving the re-planned driving route, compare the determined previous infrared sensor with infrared sensors that have been recently marked as passed in invalid driving routes, and update the re-planned driving route to a corresponding invalid driving route if the previous infrared sensor is the same as the infrared sensor that has been recently marked as passed in the invalid driving routes. The invention updates the re-planned driving route, and can realize accurate navigation of the vehicle even if the vehicle enters the wrong road section.
In addition, as shown in fig. 6, the controller at the exit end of each road segment further includes a display control unit, where the display control unit is configured to determine, for a current infrared sensor in current detection information provided by other controllers, whether the current infrared sensor is an infrared sensor at the entrance end of the road segment where the controller is located, and if so, control display of the display according to a positional relationship between the road segment where the current infrared sensor is located and a next-level road segment in the determined driving route when it is determined that a vehicle triggering an output signal of the current infrared sensor travels on the driving route. According to the invention, after the vehicle travels to the road section entrance end, the display is controlled according to the position relation between the road section where the current infrared sensor is located and the next-level road section in the determined traveling route, and the display is controlled and displayed when the vehicle travels on the traveling route, so that the timeliness and the accuracy of display can be improved.
