Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses a light control method of an underground parking lot, which is applied to a mobile terminal 1 and a server 2 by referring to FIG. 1, wherein the server 2 generates guide path information based on a guide request operation triggered manually, and acquires real-time position information through the mobile terminal 1, the server 2 judges whether a real-time position corresponding to the real-time position information is in a path corresponding to the guide path information,
if the real-time position corresponding to the real-time position information is in the path corresponding to the guidance path information, the server 2 matches the road section information corresponding to the road section where the real-time position corresponding to the real-time position information is located, and executes the node information corresponding to the road section information based on a preset first lighting control method.
And if the real-time position corresponding to the real-time position information is not in the path corresponding to the guiding path information, the server 2 sends alarm information to the mobile terminal 1.
The mobile terminal 1 may be a smart phone, a tablet computer, or the like, and the mobile terminal 1 needs to have a wireless connection function, because the underground parking lot interferes with signals of the mobile network, which may cause an influence on data transmission in the mobile network. Therefore, a wireless local area network is built in the underground parking lot, and the mobile terminal 1 is connected to the wireless local area network, so that data transmission with the server 2 is realized. The user operates through a parking lot APP or a small program installed on the mobile terminal 1 to generate a guiding request instruction, the server 2 responds to the guiding request instruction to generate guiding path information, meanwhile, the server 2 generates real-time position information according to the position of the underground parking lot where the mobile terminal 1 is located, as long as the user acts according to the guiding path information given by the server 2, the real-time position corresponding to the real-time position information can be always located on a path corresponding to the guiding path information, and therefore the server 2 can control indicator lamps installed along the path to sequentially emit light to provide guidance for the user.
The alarm information is generated by the server 2 and then transmitted to the corresponding mobile terminal 1 to remind the user of the action according to the guidance of the indicator lamp.
A light control method for an underground parking lot comprises the following steps:
and S100, generating guiding path information based on manually triggered guiding request operation.
The method specifically comprises the following steps:
acquiring route searching request information and parking point number information;
acquiring initial position information based on the route searching request information, and acquiring destination information based on the parking spot number information;
and analyzing a plurality of pieces of preselected path information according to the initial position information and the destination information, analyzing path crossing times of the preselected path information and the obstacle path information one by one, and selecting the preselected path information with the minimum path crossing times to convert the preselected path information into guide path information.
The route searching request information and the parking spot number information are generated by the mobile terminal 1 and transmitted to the server 2 by the mobile terminal 1, so that the server 2 generates the guiding path information. The initial position represented by the initial position information is actually the position of the mobile terminal 1 when the route search request information is issued.
The user's operation on the mobile terminal 1 not only clicks the virtual key of the "route search request" to generate route search request information, but also inputs the parking spot number of the location where the own vehicle is parked to generate parking spot number information, thereby causing the mobile terminal 1 to transmit the route search request information and the parking spot number information to the server 2.
The obstacle path information is guidance path information that has been generated after being initiated by other users in the parking lot.
The guidance path information includes a plurality of pieces of section information and node information corresponding one-to-one to the section information.
The road section represented by the road section information is a straight line section for vehicles and people to pass through in the underground parking lot, only two ends of the straight line section have turnouts, and the rest parts of the straight line section have no other passing selection. It should be noted that the present embodiment refers to the traffic selection for vehicle driving. The straight line segments represented by the multiple segment information in the same guidance path information can be combined into a complete path from beginning to end, and the path is the guidance path corresponding to the guidance path information and guiding the user to advance.
The node information includes area identification information and light color information. The area identification information represents the area where the indicator lamp located between the adjacent straight line sections is located, the light color information represents the color of the indicator lamp corresponding to the area identification information when the indicator lamp emits light, the light color information of different guiding path information is different, and when the guiding path information is generated, the server 2 transmits the light color information to the mobile terminal 1 so that a user can understand the light color for guiding the forward movement of the mobile terminal.
It can be seen that the area identification information is associated with both the two adjacent linear segments, and as to which linear segment corresponds to the area identification information, it is determined according to the overall guidance direction of the guidance path information, for example, in one guidance path, a user needs to go through the linear segment a first and then break through the area B and then enter the linear segment C, and then in the current guidance path information, the area identification information corresponding to the area B corresponds to the linear path information corresponding to the linear segment a. Conversely, in another guiding path, the user needs to enter the straight line segment a after passing through the straight line segment C and then passing through the area B, and the area identification information corresponding to the area B corresponds to the straight line path information corresponding to the straight line segment C.
The position of the mobile terminal 1 to be located in the underground parking lot is greatly different from the position of the mobile terminal 1 obtained on the ground, because the mobile terminal 1 located underground cannot accurately obtain the GPS data due to the mall blocking signal above the underground parking lot, and therefore the position of the mobile terminal 1 cannot be simply obtained by means of GPS location. It is necessary to install the locator 3 for identifying the mobile terminal 1 in the underground parking lot, and the locator 3 can sense the mobile terminal 1 when the mobile terminal 1 approaches the locator 3. Once the locator 3 senses the mobile terminal 1, the location where the locator 3 is installed can be used as the current location of the mobile terminal 1. The sensing range of the locators 3 is limited, so that the situation that one mobile terminal 1 is sensed by two locators 3 at the same time does not occur. Because the mobile terminal 1 and the server 2 need to be connected in a wireless manner, the locator 3 and the mobile terminal 1 can be sensed in a bluetooth connection manner, and the locator 3 and the server 2 can be in a wireless connection or a wired connection. In addition, in order to consider effective control cost, the locator 3 is installed one in the middle of each road section, and thus the position of the mobile terminal 1 can also be understood as the position of the road section on which the mobile terminal 1 is located.
The route searching request information includes unique information of the mobile terminal 1 used by the user, such as a mobile phone number or a unique number, so that when the mobile terminal 1 is connected with any locator 3 for the first time after the route searching request information is sent out, the server 2 identifies the mobile terminal 1 according to the unique information, and a straight line segment where the locator 3 connected with the mobile terminal 1 is located is defined as an initial position. After the initial position information and the destination information, the server 2 generates the shortest path from the straight line section corresponding to the initial position information to the straight line section corresponding to the destination information according to the pre-stored electronic map of the underground parking lot.
Since a road segment in an underground parking lot often has a plurality of adjacent road segment connections, there are many choices of routes, and thus it is possible to generate a plurality of shortest routes. Therefore, it is necessary to select an optimal path from the plurality of paths for guiding the user. The criterion is chosen to be as much as possible overlapping with the existing guide path.
In one embodiment, the method for converting the preselected path information with the least path crossing times into the guiding path information comprises the following steps:
judging whether the path crossing times are zero or not,
if the path crossing times are zero, acquiring lighting color information from a pre-stored basic color information set based on a first color selection method to serve as selected color information;
if the path crossing times are not zero, obtaining the lamplight color information in the guide path information overlapped with the preselected path information, removing the existing lamplight color information from the basic color information set to form a residual color information set, and obtaining one piece of lamplight color information from the residual color information set as the selected color information based on a second color selection method;
and generating guide path information together according to the pre-selection path information and the corresponding selected color information.
The light color information includes monochromatic information and color mixing information. The indicator lights in one area are of various types, each type of indicator light corresponds to a single color light, and when the indicator lights of various types jointly emit light, a mixed color light can be generated. The single color information corresponds to one type of indicator light, and the mixed color information corresponds to multiple types of indicator lights. For example, an area has a red light, a green light, and a blue light, which can generate 7 different light colors of red light, green light, blue light, red-green light, red-blue light, blue-green light, and red-blue-green light. The basic color information set is the set of all the light colors in the underground parking lot.
A first color selection method, comprising the steps of:
and extracting all the monochromatic information from the basic color information set to form a monochromatic information set, and randomly selecting one piece of monochromatic information from the monochromatic information set as the selected color information.
The second color selection method comprises the following steps:
judging whether monochrome information exists in the residual color information set or not, and if the monochrome information exists in the residual color information set, randomly selecting one piece of monochrome information as the selected color information;
and if the monochrome information does not exist in the residual color information set, randomly selecting one mixed color information as the selected color information.
Since the mixed-color light needs to be generated by matching at least two types of indicator lamps, more resources need to be used, and therefore, the single-color light is selected as soon as possible when the light color is selected from the basic color information set.
When the single color information is selected by the existing guiding path information, the random operation is performed from the mixed light information. And when all the colors are selected, selecting from the monochromatic light information again, and simultaneously giving an alarm to the background. When the background receives frequent alarms, more types of indicator lamps can be added to the underground parking lot.
S200, acquiring the real-time position information, judging whether the real-time position corresponding to the real-time position information is in the path corresponding to the guiding path information,
if the real-time position corresponding to the real-time position information is in the path corresponding to the guide path information, matching road section information corresponding to a road section where the real-time position corresponding to the real-time position information is located, and executing node information corresponding to the road section information based on a preset first lighting control method to control an indicator light corresponding to the node information to light;
and if the real-time position corresponding to the real-time position information is not in the path corresponding to the guide path information, sending alarm information.
The acquisition of the real-time position information is consistent with the acquisition of the initial position information, and the server 2 can generate corresponding real-time position information by sensing the locator 3 of the mobile terminal 1 when the user walks near the locator 3 of one straight line segment.
A first lighting control method includes the steps of:
the information of the node to be executed is acquired,
judging whether the same area identification information exists in the node information which is needed to be executed by the node at the same time,
if the same area identification information exists, different lighting color information corresponding to the same area identification information is executed in turn;
and if the same node information does not exist, directly executing corresponding light color information.
If the same region identification information exists in the same time node, it indicates that at least two users are to meet at the same branch, and the light color information corresponding to the users may interfere with each other. For example, one user for blue-green light and another user for blue light. For the convenience of distinguishing, the server 2 controls the two types of lights to appear in turn.
There is also a case where a user who has just repeated light color information meets at one turnout due to an excessive amount of users who need guidance, resulting in repeated light color information. In order to avoid guiding errors, the server 2 not only displays the lights in turn, but also controls the corresponding indicator lights to emit light in turn according to the advancing direction of the corresponding guide path.
After the user finds the parking space, the user needs to drive the vehicle to leave the underground parking lot from the exit of the underground parking lot. The number of exits of the underground parking lot is large, but it is difficult for a user who finds a parking position by guidance to find a proper exit of the underground parking lot, and the user is likely to go out from an exit far from the parking position in the underground parking lot following an exit signboard, resulting in a waste of more time for the user. Therefore, in order to further reduce the time wasted by the user in the underground parking lot, the user can also match the departure path by submitting a departure request, and the specific method comprises the following steps:
the method comprises the steps of obtaining departure request information, obtaining current vehicle position information according to the departure request information, obtaining exit position information based on a preset exit selection method, and analyzing departure path information according to the vehicle position information and the exit position information.
The departure request information is also generated by the user operating on the mobile terminal 1 and transmitted from the mobile terminal 1 to the server 2. The vehicle position information is the same concept as the initial position information and the real-time position information, and is the straight line segment information where the locator 3 connected to the mobile terminal 1 is located.
The preset exit selection method comprises the following steps: acquiring vehicle entry record information, judging whether the times represented by the vehicle entry record information exceed a preset value,
if the times represented by the vehicle entrance record information exceed a preset value, acquiring exit position information corresponding to an exit closest to the vehicle position corresponding to the vehicle position information;
and if the times represented by the vehicle entrance record information are less than or equal to a preset value, acquiring exit position information corresponding to an exit closest to the vehicle entrance position.
The vehicle entrance record information is generated by sensing the vehicle license plate information through an intelligent barrier at the entrance of the underground parking lot when the vehicle enters the underground parking lot, and is stored in the server 2. If the vehicle entry record information corresponding to the same license plate information is stored in the server 2 before, the original vehicle entry record information is updated by adding the times represented by the original vehicle entry record information. The preset values are manually set parameters, and are generally 3 times. If the times represented by the vehicle entrance record information are less than or equal to a preset value, the default user is not familiar with the underground parking lot and the nearby roads, and the user needs to be guided back to the familiar road, namely the road where the entrance of the user enters the underground parking lot; otherwise, the default user is familiar with the underground parking lot and the nearby roads, and selects the exit closest to the vehicle position to accelerate the user departure speed.
The embodiment of the application also discloses a light control system of the underground parking lot, which is shown in fig. 1 and comprises a mobile terminal 1 and a server 2.
The mobile terminal 1 generates initial position information and real-time position information through the locator 3 installed in the underground parking lot, and generates routing request information and parking spot number information through a manual operation.
The server 2 responds to the route searching request information to generate guide path information according to the initial position information and the parking spot number information, and judges whether the real-time position corresponding to the real-time position information is in the path corresponding to the guide path information.
If the real-time position corresponding to the real-time position information is in the path corresponding to the guiding path information, the server 2 matches road section information corresponding to the road section where the real-time position corresponding to the real-time position information is located, and executes node information corresponding to the road section information based on a preset first lighting control method to control the lighting of the indicator lamp corresponding to the node information;
if the real-time position corresponding to the real-time position information is not in the path corresponding to the guiding path information, the server 2 transmits alarm information to the mobile terminal 1 to remind the user of paying attention to the guiding lamp.
A computer-readable storage medium storing a computer program that can be loaded by a processor and executes the above-mentioned method.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
