Referring to fig. 1, fig. 1 is a first parking space selection method provided in the embodiment of the present application, and a detailed scheme of the method is specifically described below. The method may include step 100, step 120, and step 140.
Wherein the step 100: classifying the acquired parking space information of the parking lot, and respectively storing the classified parking space information into a first cache region and a second cache region; and the rest parking space information in the parking space information is stored in the second cache region.
For example, the acquired parking space information of the parking lot may be the total amount of static information of the parking lot acquired by the parking system from the service provider. The parking system integrates social parking resources in the whole city, integrates urban parking lot information, is established into an intelligent parking lot public service system facing the city, and provides static and dynamic parking guidance information for a driver by using tools such as a three-level electronic guidance board, an internet website, a mobile phone terminal, a vehicle-mounted GPS (global positioning system), a CMMB (China mobile multimedia broadcasting) television, a radio station, telephone service and the like. The parking lot information can specifically comprise various static parking place information such as parking lot positions, parking place information, road traffic states related to driving routes, parking place charging rules and the like, and the information can guide a driver to quickly find the parking lot.
The method comprises the following steps of firstly storing various acquired static parking space information into a database, simply classifying the parking space information stored in the database, and then randomly distributing two buffer areas from a memory space: the first cache region and the second cache region temporarily store the part of the information of the rest parking spaces in the parking space information in the second cache region according to the classification result, and all the rest other information can be temporarily stored in the first cache region. Wherein, remaining parking stall information can be the parking stall at present time not berth the vehicle, be in idle state, the relevant information that the parking stall is unoccupied promptly, for example, remaining parking stall information can include: the number of the remaining parking spaces and/or the parking lot identifications of the remaining parking spaces, and the like.
Step 120: and correspondingly updating the remaining parking space information stored in the second cache region according to the sensing data of the parking space sensors of the parking lot to obtain real-time remaining parking space information.
For example, the parking space sensor may be an infrared sensor or an ultrasonic sensor for sensing whether the corresponding parking space is parked. When the vehicle finishes warehousing, the parking space sensors arranged on corresponding parking spaces generate sensing data of the vehicle warehousing; and when the vehicle finishes the garage-out, the parking space sensors arranged on the corresponding parking spaces generate sensing data of the vehicle after the vehicle leaves the garage.
The parking space sensor transmits the generated sensing data to a cloud database of a target area where a user is located through a network, the parking system can obtain the sensing data generated by the parking space sensor from the cloud database by initiating an http request, and then corresponding updating is carried out on the remaining parking space information temporarily stored in the second cache region according to the sensing data, so that the current latest real-time remaining parking space information is obtained. The network transmission mode may be a wireless transmission mode or a wired transmission mode, and the wireless transmission mode may be a radio frequency transmission mode, an NFC near field communication transmission mode, a bluetooth transmission mode, or a wireless network transmission mode.
Step 140: comprehensively sorting the real-time remaining parking space information according to the parking space information stored in the first cache region to obtain a comprehensive sorting result; and the comprehensive sequencing result is used for the user to select the parking space.
Illustratively, the dynamic updated real-time remaining parking space information of the second cache area is comprehensively sorted into the optimal parking lot and the optimal parking space by combining the static parking space information such as the position of the parking lot temporarily stored in the first cache area, and the comprehensive sorting result is returned to the terminal, so that the user can select the appropriate and optimal parking space at the terminal according to the result. The data are acquired, updated and sequenced in the cache region, and the dynamic allocation data of the parking spaces are acquired in real time, so that the timeliness of the remaining parking spaces of the current parking lot is guaranteed, the phenomenon of repeated parking searching can be effectively reduced, and the parking cost of a driver is reduced.
Referring to fig. 2, fig. 2 is a second parking space selection method according to an embodiment of the present application, and a detailed scheme in fig. 2 is specifically described below. In one embodiment, step 140 may specifically include: step 141, step 142, step 143, and step 144.
Wherein, step 141: and acquiring a target parking lot in the query range from the first cache region based on a parking space query request triggered by the user at the current position.
For example, the parking space query request triggered by the user at the current position may originate from a vehicle-mounted terminal of a vehicle driven by the user, on which a parking space information query platform is operated. The parking space information inquiry platform can be an application program developed by a user or a third-party platform. The query scope may be a scope of autonomous search by the user, for example, 10km near the current location.
When receiving a parking space query request sent by a parking space information query platform operating on a terminal, a parking system acquires current longitude and latitude position information of a user and position information independently searched by the user based on the query request, for example: and parking lots within a range of 10km around, acquiring the initially cached parking lot position information from the first cache region, and extracting the parking lot position information within a range of 10km around the current longitude and latitude position of the user from the initially cached parking lot position information.
Step 142: calculating the linear distance between the current position and the target parking lot position according to the target parking lot position stored in the first cache region;
step 143: sequencing the target parking lots according to the numerical value of the linear distance to obtain a first sequencing result; and
step 144: and matching the real-time remaining parking space information to the first sequencing result to obtain a comprehensive sequencing result.
Illustratively, a plurality of pieces of parking lot position information within a range of 10km around the current longitude and latitude position of the user are extracted from a first cache region, the linear distances between the current position and the parking lot positions are respectively calculated in the cache region, distance comparison is carried out, the parking lots are digitally sorted according to the distance, and a first sorting result is obtained, wherein: the numerical sequence represents the distance sequence of all the parking lots to be selected in the target parking lot set, and the smaller the numerical value is, the closer the selection distance is.
Furthermore, the currently updated real-time remaining parking space information of the second cache area is sequentially matched with the sorted parking lots, that is, the corresponding real-time remaining parking spaces are mapped into the sorting result one by one according to the parking lot identifications of the parking lots, and finally, the matched comprehensive sorting result is returned to the parking space information query platform for displaying. According to the priority sequencing of the distances between the parking spaces and the dynamic updating parking spaces, mapping matching is carried out by combining the dynamic updating parking spaces, static parking space information and dynamic parking space information are comprehensively utilized, and a user can select a better and more appropriate parking space.
In one embodiment, step 100 may specifically include: step 101 and step 102.
Wherein, step 101: storing the parking lot position, the parking lot identification, the parking space identification, the total parking space number and the number of the parked parking spaces in the parking space information to a first cache region;
step 102: and storing the parking lot identification and the number of the remaining parking spaces corresponding to the remaining parking space information in the parking space information into a second cache region.
The parking space information may be, for example, total static parking space information of a parking lot obtained by the parking system from a service provider, and may specifically include various static parking space information such as a parking lot position, parking space information, a road traffic state related to a driving route, and a parking space charging rule. The parking space information may include a parking lot identification, a parking space identification, a total number of parking spaces, a number of parked parking spaces, and a number of unparked parking spaces (a remaining number of parking spaces). The parking lot identifier or the parking space identifier may be a unique name or ID used for representing the parking lot or the parking space through one or more of numbers, characters or character strings.
Firstly, simply classifying parking space information stored in a database, then opening up two memory spaces by a parking system to be respectively used as a first cache region and a second cache region, wherein the first cache region can temporarily store other static parking space information except two information such as a parking lot identifier, the number of parking spaces and the like in a general set form; and the second cache region temporarily stores static parking place information such as the identification of the parking lot, the number of the remaining parking places and the like. The remaining parking space information needing to be updated is preferentially stored in the other cache region, errors are avoided during data updating, and the data processing efficiency can be improved.
In one embodiment, step 102 may specifically include: step 102 a.
Step 102 a: and taking the parking lot identification in the remaining parking space information as a key, taking the number of the remaining parking spaces as a value, and storing the value in a key value pair mode to a second cache region.
For example, the remaining parking space information may include: the number of remaining parking spaces and/or the parking lot identification of the remaining parking spaces. Therefore, the parking lot identification can be used as a key (key) corresponding to the key-value pair (key-value) in the second cache region, the number of the remaining parking spaces is used as a value (value) corresponding to the key-value pair (key-value), and caching is performed in a data structure storage mode of the key-value pair.
In one embodiment, step 120 may specifically include: step 121 and step 122.
Wherein, step 121: acquiring sensing data of a parking space sensor corresponding to each parking space in a parking lot; the sensing data is automatically generated by sensing whether the corresponding parking space is occupied or not by the parking space sensor;
step 122: and correspondingly updating the remaining parking space information stored in the second cache region according to the sensing data to obtain real-time remaining parking space information.
For example, each parking space may be provided with a corresponding parking space sensor. When the vehicle finishes warehousing, namely when the current parking space is occupied, the parking space sensors arranged on the corresponding parking spaces automatically generate sensing data of the vehicle warehousing; when the vehicle is taken out of the garage, namely the current parking space is not occupied, the parking space sensors arranged on the corresponding parking spaces automatically generate sensing data of the vehicle which is taken out of the garage. And receiving the two sensing data, and performing corresponding increase and decrease updating on the number of the remaining parking spaces in the remaining parking space information in the second cache region, so that real-time remaining parking space information with the number of the remaining parking spaces updated in real time can be obtained. The condition that whether the parking spaces are occupied or not is acquired in real time according to the parking space sensors arranged in each parking space, real-time updating of dynamic data of the cache region is achieved, and timeliness and optimality of the final parking lot and parking space sequencing results are guaranteed.
In one embodiment, step 122 may specifically include: step 122a and step 122 b.
Wherein, step 122 a: if the acquired sensing data indicate that the corresponding parking space has a warehousing behavior, quantity increasing and updating the remaining parking space information stored in the second cache region to obtain real-time remaining parking space information;
step 122 b: and if the acquired sensing data indicates that the corresponding parking space has a parking-out behavior, the number of the remaining parking space information stored in the second cache region is reduced by one, and real-time remaining parking space information is acquired.
For example, the warehousing behavior may be an action of the owner driving the vehicle into a parking space; the garage exit behavior can be the action of a vehicle owner driving the vehicle to leave a parking space. When the vehicle finishes warehousing at a certain parking stall, when the parking stall sensor perception is that the current parking stall is occupied promptly, then in the remaining parking stall information of second buffer memory district: reducing the number of the current remaining parking spaces corresponding to the parking lot by one; when the vehicle is finished leaving the garage at a certain parking space, namely the parking sensor senses that the current parking space is not occupied, then in the remaining parking space information of the second cache region: and increasing one for the current remaining parking space number corresponding to the parking lot.
Furthermore, each parking space corresponds to a unique parking lot identifier, when a vehicle parks in any target parking space in the target parking lot identifier area, the parking space sensors on the corresponding target parking spaces generate sensing data according to detected warehousing or ex-warehousing behaviors, and the sensing data are transmitted to a parking system in a wired or wireless mode. The parking space sensor informs the parking system of the addition and subtraction condition of the parking space of the parking lot according to the behavior of the car owner driving away or into the parking space in the parking lot, and the parking system performs addition and subtraction on the number of the remaining car positions in the parking lot in the second cache region, so that the dynamic updating of the remaining parking space is realized, the timeliness of dynamic data is guaranteed, and the accuracy of the sequencing result is improved.
In one embodiment, the first cache region and the second cache region are operating memories.
Illustratively, the run-time memory, which may also be referred to as main memory, may refer to the memory required by the program during run-time, which is only capable of temporarily storing data for exchanging cache data with the CPU. The operating memory here may be RAM random access memory. The first cache region and the second cache region are both running memories, so that compared with a hard disk or other storage devices, the parking system can write in and read out data from the first cache region and the second cache region more quickly, and therefore the terminal query efficiency and the dynamic processing efficiency of the remaining parking space data are improved.
