Description

Technical Field

[0001] The present invention relates to the field of intelligent charging of new energy vehicles and computer vision technology, and in particular to a method and device for guiding vehicles in a charging station based on reservation. Background Art

[0002] With the increase in the number of electric vehicles, the demand for charging is increasing. The supervision and operation of charging stations need to be more intelligent to improve user experience. The existing video surveillance system of charging stations is mainly used for security monitoring: video surveillance can view the environment and personnel activities in the charging station in real time, and timely discover and prevent potential public security problems, such as theft, damage to public facilities, fire warning, etc. However, station monitoring still has shortcomings in station operation, intelligent management and communication with charging vehicles.

[0003] The charging process of a vehicle is usually that when the owner finds that the vehicle is low on power, he checks whether there are available charging piles at nearby charging stations, drives to the target charging station with available charging piles, and searches for charging piles after the vehicle enters the charging station. If the charging pile has a ground lock or a gate, it is necessary to scan the code to unlock it and drive the vehicle to the location of the charging pile to charge and recharge. However, the charging process has the following shortcomings:

[0004] First, the charging pile may be occupied while the car owner is driving to the target charging station, causing the available charging pile at the time of departure to become unusable when the car arrives and cannot be charged;

[0005] Secondly, there is often a lack of electronic high-precision maps for the internal routes of charging stations. The internal roads of charging stations are complicated and even random parking may change the drivable routes of the internal roads. The underground parking lot has poor signals and often lacks GPS signals, resulting in navigation failure. After entering the charging station, vehicles cannot find the specific parking space where the charging pile is located, making it difficult to quickly reach the designated charging pile.

[0006] Although the prior art has proposed parking lot navigation solutions, they all rely on the terminals carried by users (mobile phones, computers, and car terminals). In real life, due to the different performance of users' terminal models, their ability to receive positioning beacons varies, and their memory and operating capabilities vary even more, making it impossible to ensure the generation of stable navigation information. Therefore, it is impossible to provide users with intuitive and easy-to-read navigation information. Even the parking lot navigation solutions proposed by the prior art rely on mobile phone cameras to complete navigation. In actual operation, drivers cannot operate their phones while driving due to laws and regulations and driving safety. The lack of a mobile phone holder in the car for shooting road information makes it difficult for the mobile phone camera to capture images stably. The underground parking lot or the night parking lot is dimly lit, and it is difficult for both mobile phones and driving recorders to capture clear images, making it impossible to complete navigation.

[0007] Furthermore, the car owner needs to scan the code to open the ground lock or gate. Although the existence of the ground lock and gate ensures that the charging pile is not illegally occupied, it also reduces the efficiency of energy replenishment.

[0008] Finally, in the prior art, the charging pile will display its working status for maintenance personnel or users, but both maintenance personnel and users need to observe the charging pile closely to understand the charging information, without considering the driver's need to observe whether the charging pile is available from a distance before entering the parking space. As a result, the driver often finds that the charging pile is unavailable or damaged after getting off the car and approaching it, so he has to reverse out of the parking space and go to the next parking space, which seriously reduces the user experience. Summary of the invention

[0009] In view of the problems of poor charging experience and low efficiency in existing technologies, such as Figure 1 As shown, the present invention proposes a method for guiding vehicles in a charging station based on scheduled charging, which includes:

[0010] Charging reservation step S1: the station server selects idle charging piles in the charging station to form a charging pile candidate list, and the user selects a charging pile from the charging pile candidate list as a reserved charging pile through the client;

[0011] In the driving guidance step S2, the station server pulls the video streams of each camera in the charging station, identifies that the reserved vehicle enters the charging station, and obtains the position of the reserved vehicle through the video stream and the target recognition and positioning algorithm; the station server plans the entry path from the position of the reserved vehicle to the reserved charging pile according to the internal road map of the charging station, and generates navigation information according to the entry path to guide the reserved vehicle to the target parking space where the reserved charging pile is located;

[0012] Vehicle charging step S3: after the station server recognizes that the reserved vehicle has arrived at the designated area of ​​the target parking space, the ground lock of the target parking space is automatically unlocked or the gate of the target parking space is automatically lifted, and the reserved vehicle enters the target parking space;

[0013] The barrier pole of the barrier or the barrier pole of the ground lock is equipped with a display device, which is used to display the navigation information or the working status information of the charging pile; and the station server controls the display device to display the navigation information within a specified radius with the reserved vehicle position as the center according to the reserved vehicle position, so as to guide the reserved vehicle to the target parking space.

[0014] The present invention implements the reservation of charging piles through the charging reservation step S1, avoids the charging piles being occupied during the process of driving to the target charging station, and improves the user experience; and through the video stream and target recognition and positioning algorithm obtained in the driving guidance step S2, high-precision positioning inside the charging station that does not rely on GPS and mobile networks is realized to provide reliable navigation information, further improve the user experience, shorten the time for each user to reach the parking space where the charging pile is located, and improve the overall charging efficiency of the charging station; through the vehicle energy replenishment step S3, there is no need to scan the code separately to open the ground lock or the gate, shortens the time for each user to enter the charging parking space, and improves the overall charging efficiency of the charging station; through the installed display device, the navigation capability is further enhanced, and the working status information of the charging pile displayed by the display device can inform the user of the charging pile status in advance, which is conducive to the user to smoothly find a suitable charging pile, such as a charging pile with matching charging speed or safety level.

[0015] like Figure 2 As shown, the method for guiding vehicles in a charging station based on scheduled charging includes:

[0016] Departure guidance step S4: When the station server recognizes that the vehicle has finished charging, the station server plans a departure path from the location of the vehicle leaving the station after charging to the station exit location based on the internal road map of the station, and generates navigation information based on the departure path to guide the vehicle leaving the station to the exit of the charging station.

[0020] The station server controls the client to send out the navigation information to guide the vehicle to a designated reserved parking space or a vacant parking space or an exit of the charging station.

[0021] In addition, the station server of the present invention has a stable communication connection with each camera in the charging station, so stable navigation information can be generated; and the present invention can provide navigation information to users through underground lights in the charging station and display devices located on gate poles and barrier poles. Under this design, users do not need to look down at their mobile phones, computers, or vehicle-mounted terminals, which undoubtedly improves the readability of navigation. That is, the present invention completely relies on limiting the hardware and connection relationships in the charging station to provide users with a stable, intuitive, and easy-to-read navigation environment without occupying the computing power of the user's mobile phone or vehicle for navigation in the charging station.

[0022] The present invention also proposes a vehicle guiding device in a charging station based on scheduled charging, comprising:

[0089] In order to make the above features and effects of the present invention more clearly and understandably described, embodiments are given below and described in detail with reference to the accompanying drawings. This specification discloses one or more embodiments that include the features of the present invention. The disclosed embodiments are only for illustration. The scope of protection of the present invention is not limited to the disclosed embodiments, and the present invention is defined by the attached claims.

[0090] Specifically, the system of the present invention includes a station server with a processor and a memory, cameras installed at various points in the station, a charging pile 1, and each charging pile 1 has a corresponding ground lock or gate. The station server can pull the video stream of each camera, perform calculations through algorithms, and obtain vehicle information. Through the installation of cameras at reasonable points and algorithms, the two-dimensional coordinates of the vehicle in the station (parking lot) can be located.

[0091] Embodiment 1:

[0092] like Figure 1 As shown, the vehicle guidance method based on scheduled charging in a station proposed in the first embodiment of the present invention includes the following application steps:

[0093] In charging reservation step S1, the station server provides the user with a candidate list of charging piles available for reservation based on the status information of the charging pile 1 in the station. The user selects an idle charging pile from the candidate list of charging piles as the reserved charging pile through the client; the reserved charging pile changes from the available state to the reserved state, and the charging pile in the reserved state cannot be used by vehicles other than the reserved vehicle; the status information includes idle state, in-use state, under repair state, damaged state, normal working state, etc. The client can be a mobile phone application APP, computer application software, etc.

[0094] In the driving guidance step S2, the station server can pull the video streams of each camera. After the station server recognizes that the user's reserved vehicle enters the station, it calculates through the video stream and the positioning algorithm based on target monitoring to obtain the position of the reserved vehicle, that is, the real-time position coordinates of the reserved vehicle in the charging station; at the same time, after the reserved vehicle enters the station, the client establishes a communication connection with the station server through local wireless communication means such as wireless network to display navigation information or use a speaker for voice navigation; the station server combines the internal road map of the station to plan the entry path from the position of the reserved vehicle to the position of the reserved charging pile in real time, and sends navigation information through the client (displays navigation information or uses a speaker for voice navigation) to guide the reserved vehicle to the target parking space 2 where the reserved charging pile is located;

[0095] The positioning algorithm can transform the coordinates of the target to be located (reserved vehicle) in the video frame, so that the target location information identified from the image is gradually mapped to the geographical location in the real world, thereby finally achieving accurate spatial positioning as the location of the reserved vehicle. The mapping process can be carried out using the traditional regular coordinate transformation formula, or a mapping scheme based on a neural network model. The target to be located in the video stream information is identified based on the trained target recognition model, the pixel coordinates of the identified target to be located are obtained and the coordinates are transformed to obtain the location of the reserved vehicle.

[0096] The vehicle energy replenishment step S3 is based on the video stream collected by the camera at the station, such as Figure 3 As shown, after the station server recognizes that the reserved vehicle has arrived at the designated area 4 of the target parking space, the ground lock of the target parking space is automatically unlocked, or the gate of the target parking space is automatically lifted, and the reserved vehicle enters the target parking space for charging. The designated area is a designated area 4 connected to the parking space entrance 3, for example, an area with a radius of 3 meters from the entrance of the target parking space.

[0097] Therefore, the present invention avoids the charging pile being occupied by other vehicles in advance while the vehicle is rushing to the charging pile by reserving the charging pile. At the same time, it avoids the cumbersome operation inconvenience caused to users by scanning codes to unlock and lifting poles, and improves the charging experience and efficiency. The location of the reserved vehicle at the station can be identified by the internal camera of the station, so as to provide navigation for the reserved vehicle, further improving the user experience and the convenience of charging.

[0098] Embodiment 2:

[0099] In addition, Figure 2 As shown, when the station server recognizes that the vehicle has finished charging, for example, when the charging gun is disconnected from the vehicle, the available charging pile that has been disconnected and ended charging is added to the charging pile candidate list; the station server plans the departure path from the location of the leaving vehicle that has finished charging to the station exit location based on the station internal road 5 map, and sends navigation information through the client to guide the leaving vehicle to the station exit. When the station server recognizes that the vehicle has left the charging parking space, the ground lock of the charging parking space is automatically locked, or the gate of the charging parking space is automatically lowered. This improves the efficiency of vehicles leaving the station and prepares for the next scheduled charging.

[0100] The vehicle guidance method in a station based on scheduled charging proposed in the second embodiment of the present invention includes the following application steps:

[0101] In charging reservation step S1, the station server provides the user with a candidate list of charging piles available for reservation based on the status information of the charging pile 1 in the station. The user selects an idle charging pile from the candidate list of charging piles as the reserved charging pile through the client; the reserved charging pile changes from the available state to the reserved state, and the charging pile in the reserved state cannot be used by vehicles other than the reserved vehicle; the status information includes idle state, in-use state, under repair state, damaged state, normal working state, etc. The client can be a mobile phone application APP, computer application software, etc.

[0102] In the driving guidance step S2, the station server can pull the video streams of each camera. After the station server recognizes that the user's reserved vehicle enters the station, it calculates through the positioning algorithm to obtain the position of the reserved vehicle; and according to the station internal road 5 map, it plans the entry path from the position of the reserved vehicle to the position of the reserved charging pile, and sends navigation information through the client to guide the reserved vehicle to the target parking space 2 where the reserved charging pile is located;

[0103] The vehicle energy replenishment step S3 is based on the video stream collected by the camera at the station, such as Figure 3As shown, after the station server recognizes that the reserved vehicle has arrived at the designated area 4 of the target parking space, the ground lock of the target parking space is automatically unlocked, or the gate of the target parking space is automatically lifted, and the reserved vehicle enters the target parking space for charging. The designated area is a designated area 4 connected to the parking space entrance 3, for example, an area with a radius of 3 meters from the entrance of the target parking space.

[0104] Departure guidance step S4: When the station server recognizes that the vehicle has finished charging, for example, when the charging gun is disconnected from the vehicle, the available charging pile that has been disconnected and ended charging is added to the candidate list of charging piles; the station server plans the departure path from the location of the departing vehicle that has finished charging to the station exit location based on the station internal road 5 map, and sends navigation information through the client to guide the departing vehicle to the station exit. When the station server recognizes that the vehicle has left the charging parking space, the ground lock of the charging parking space is automatically locked, or the gate of the charging parking space is automatically lowered. This improves the efficiency of the vehicle leaving the station and prepares for the next scheduled charging.

[0105] Embodiment three:

[0106] A speaker or display device for voice reminders to users is installed in the station. For example, when a user gets lost and cannot find his vehicle, the station server can identify the user's location and the location of his vehicle based on the station's camera. Not only can the user be notified of the location of his vehicle through the client, but the speaker or display device installed in the station can also be used to inform the user of the vehicle's location and guide him to arrive. Or when a user encounters a problem using the station, such as charging, finding a vehicle, or reporting a repair problem, the speaker or display device can be used to inform the user of the solution to the problem. This can solve problems for users in a timely and convenient manner, further improving the user experience.

[0107] The vehicle guidance method in a station based on scheduled charging proposed in the third embodiment of the present invention further includes in the above-mentioned vehicle energy replenishment step S3:

[0108] Step S31, save the target parking space position and the ID (vehicle license plate, vehicle identification number) of the reserved vehicle. The vehicle identification number is determined according to the national vehicle management standards and includes the vehicle manufacturer, year, model, body type and code, engine code and assembly location.

[0109] The departure guidance step S4 includes:

[0110] Step S41, when the user cannot find the vehicle, the user sends a vehicle search instruction through the client, and the camera or signal sensor in the station obtains the user's location. After receiving the vehicle search instruction, the station server retrieves the location information of the vehicle ID in the charging station according to the vehicle ID in the vehicle search instruction, and constructs navigation information according to the location information, the internal road map of the station and the user's location, and outputs the navigation information through the client and / or the speaker or display device in the station to guide the user to the vehicle location. In this way, the user and vehicle location information calculated using the video data collected by the internal LAN and camera of the station can be used without relying on the mobile network or cellular network, thereby improving the positioning accuracy and avoiding the problem of low positioning reliability caused by unstable GPS signals. Even if the mobile network signal or GPS signal in the underground garage or parking lot in the building complex where the user is located is insufficient, reliable navigation information can still be provided to the user.

[0111] Embodiment 4:

[0112] The present invention may also include an underground lamp installed on the internal road 5 of the station, and the underground lamp is connected to the station server through a network cable (wifi), and the station server controls the underground lamp to light up, which is used to guide the vehicle to the parking space 2 or the station exit. The underground lamp can be an RGB color lamp, which guides the vehicle by color, or the underground lamp is lit in sequence, and the vehicle is guided by the lighting order and direction, or the underground lamp is lit according to a specified pattern, and the vehicle is guided by the arrow direction displayed by the pattern. In this way, the vehicle driver can obtain navigation information more intuitively and improve navigation efficiency. Specifically, accurate navigation in the charging station can calculate the distance between the vehicle license plate and the camera through the station location camera and algorithm, and obtain the two-dimensional coordinates of the vehicle in the station. When the vehicle enters the range of the predetermined parking space, it will automatically lower the lock, and the vehicle can be optionally guided to enter the predetermined parking space by sound and light. If there is no predetermined vehicle or non-electric vehicle, the ground lock will not be lowered. Obtain a two-dimensional plan of the station, and arrange a certain number of cameras on a two-dimensional plane of the station to monitor the lanes and parking spaces. Each camera has a specific installation position (two-dimensional coordinates) and shooting angle. When a vehicle enters. The device obtains the camera video stream and can calculate the license plate number / the distance / angle between the license plate and the camera. Through trigonometric functions (cos / sin, etc.), the two-dimensional coordinates of the vehicle can be calculated. This controls the underground lights to guide the vehicle to the designated parking space.

[0113] The station server has an algorithm to determine whether there is a car in the parking space, and is linked to the ground lock. Abandoning the existing ground lock that uses radar and ground sensor coils as the basis for judging whether there is a car signal, the present invention combines the camera to collect images to confirm whether there is a car in the parking space, whether there is a car charging in the parking space, and whether there is a car in the parking space, thereby improving the accuracy of judgment.

[0114] When vehicles enter the parking lot, each vehicle is assigned a color. The station server lights up a certain number of underground lights in front of the vehicle based on the vehicle's real-time location, and turns off the underground lights that have already passed, to guide the vehicle into the parking space.

[0115] The vehicle guidance method in a station based on scheduled charging proposed in the fourth embodiment of the present invention further includes in the above-mentioned entry guidance step S2:

[0116] Step S21: The station server can pull the video streams of each camera. After the station server recognizes that the user's reserved vehicle enters the station, it calculates through the positioning algorithm to obtain the position of the reserved vehicle; and according to the station internal road 5 map, it plans the entry path from the position of the reserved vehicle to the position of the reserved charging pile, sends navigation information through the client, and lights up the underground lights on the entry path to guide the reserved vehicle to the target parking space 2 where the reserved charging pile is located; or

[0117] Step S22, the station server can pull the video stream of each camera. After the station server recognizes that the user's reserved vehicle enters the station, it calculates through the positioning algorithm to obtain the position of the reserved vehicle; assigns a specified color to the user or the reserved vehicle, and plans an entry path from the position of the reserved vehicle to the position of the reserved charging pile according to the station internal road 5 map, sends navigation information through the client, guides the reserved vehicle to the target parking space 2 where the reserved charging pile is located, and controls the underground lights on the entry path to emit the specified color, guiding the reserved vehicle to the target parking space 2 where the reserved charging pile is located according to the underground lights of the corresponding color; thereby avoiding confusion in the navigation content displayed by the underground lights when guiding multiple vehicles at the same time. When multiple vehicles need to navigate, the underground lights cannot simultaneously carry the task of displaying multiple colors, and can flash and alternately display the specified colors to provide navigation information for multiple vehicles. Or

[0118] Step S23, the station server can pull the video stream of each camera. After the station server recognizes that the user's reserved vehicle enters the station, it calculates through the positioning algorithm to obtain the position of the reserved vehicle; and according to the internal road 5 map of the station, it plans the entry path from the position of the reserved vehicle to the position of the reserved charging pile, sends navigation information through the client, and lights up the underground lights on the entry path to display specific shapes, such as arrows, speed limit signs, pass signs, and waiting signs. The reserved vehicle is guided to drive in the direction of the arrow, and the vehicle is reminded to drive at a low speed in the station through the speed limit sign. The traffic in the station is guided by the pass sign and the waiting sign, and finally the reserved vehicle is guided to the target parking space 2 where the reserved charging pile is located.

[0119] Correspondingly, the departure guidance step S4 also includes:

[0120] Step S41, when the station server recognizes that the vehicle has finished charging, for example, when the charging gun is disconnected from the vehicle, the available charging pile that has been disconnected and ended charging is added to the charging pile candidate list; the station server plans a departure path from the location of the leaving vehicle that has finished charging to the station exit location based on the station internal road 5 map, sends navigation information through the client, and lights up the underground lights on the departure path to guide the leaving vehicle to the station exit; or

[0121] Step S42: When the station server recognizes that the vehicle has finished charging, for example, when the charging gun is disconnected from the vehicle, the available charging pile that has been disconnected and ended charging is added to the candidate list of charging piles; a specific color is assigned to the departing vehicle, and the station server plans a departure path from the position of the departing vehicle that has finished charging to the station exit position according to the station internal road 5 map, sends navigation information through the client, and lights up the underground lights on the departure path to guide the departing vehicle to the station exit; at the same time, the underground lights on the entry path are controlled to emit the specific color, and the departing vehicle is guided to the station exit according to the underground lights of the corresponding color; thereby avoiding confusion in the navigation content displayed by the underground lights when guiding multiple vehicles at the same time. When multiple vehicles need navigation guidance, the underground lights cannot simultaneously carry out the task of displaying multiple colors, and can flash and alternately display the specified colors to provide navigation information for multiple vehicles;

[0122] Step S43, when the station server recognizes that the vehicle has finished charging, for example, when the charging gun is disconnected from the vehicle, the available charging pile that has been disconnected and ended charging is added to the candidate list of charging piles; the station server plans a departure path from the location of the departing vehicle that has finished charging to the station exit location based on the internal road 5 map of the station, sends navigation information through the client, and lights up the underground lights on the departure path to guide the departing vehicle to the station exit; at the same time, the underground lights on the entry path are lit to display specific shapes, such as arrows, speed limit signs, pass signs, and waiting signs, and the reserved vehicle is guided to travel by the arrow direction, and the vehicle is reminded to drive at a low speed in the station by the speed limit sign, and the traffic in the station is diverted by the pass sign and waiting sign, and finally the reserved vehicle is guided to the station exit.

[0123] Embodiment five:

[0124] The above-mentioned entry guidance step may further include:

[0125] After the reserved vehicle arrives at the parking lot, the client (charging APP) is used to interconnect the in-station navigation with the map APP. After entering the station, the in-station navigation is directly activated.

[0126] The algorithm used by the station's camera to identify the vehicle position mainly includes: calculating the distance and angle between the target vehicle (reserved vehicle or departing vehicle) and the camera through the camera algorithm, and then obtaining the specific position of the target vehicle in the parking lot through trigonometric calculations based on the camera installation position, and accurately determining the two-dimensional coordinate position of the vehicle.

[0127] In the prior art, the charging pile will display its working status, but the display object is maintenance personnel or users. Maintenance personnel or users need to observe the charging pile closely to understand the charging information, but they do not consider the need of the driver to observe whether the charging pile is available from a distance before entering the parking space. As a result, the driver often finds that the charging pile is unavailable and damaged after getting off the car and approaching it, so he has to reverse out of the parking space and go to the next parking space. In view of this situation, the present invention can also install a display device 8 for displaying information for the charging pile 1, the gate or the ground lock. The display device 8 is connected to the station server and can display the working status of the charging pile 1 according to the station server command signal. It can display the working status representing idle, reserved or faulty. The display screen of the display device 8 can display navigation information according to the station server command signal, and display direction arrows to have navigation indication functions. The display device 8 can be an organic light emitting display (OLED), a light emitting diode display LED or a liquid crystal display, but is not limited thereto.

[0128] Since the charging pile 1 is often located at the end of the parking space 2, when a vehicle is parked in the adjacent parking space 2, the charging pile 1 at the end of the parking space 2 will be blocked. Figure 4 , 5 As shown in , 6 and 7, it is preferred to set a display device 8 at the gate or ground lock so that the display device 8 is closer to the parking space entrance 3 and easier for passing vehicles to identify. For example, the display device 8 is installed on the gate pole 7 of the gate or the barrier rod 10 of the ground lock. The display device 8 can display different colors and patterns to represent specified information. For example, when a specified pattern is displayed, it represents the working status of the charging pile, such as available, unavailable, charging, and maintenance. In this way, the vehicle can obtain the working status of the charging pile earlier, without having to find that the charging pile is unavailable after entering the parking space or connecting the charging gun, and can only reverse back to continue looking for the next charging pile.

[0129] Embodiment six:

[0130] Furthermore, in order to better display the charging information and allow the user to see the display content of the display device earlier, it should be as follows Figure 8 As shown, the gate or ground lock is arranged as far as possible to the front end of the parking space, that is, to a position in the parking space away from the charging pile 1, but this will cause the traditionally arranged gate or ground lock to lose the ability to occupy the parking space, and cannot prevent non-charging vehicles from occupying the parking space.

[0131] For this purpose, the present invention further proposes the following on the basis of the above-mentioned embodiment 5: Fig. 9 or Fig.10 The rear barrier shown in the figure is different from the traditional barrier in that the barrier box 6 of the rear barrier is not installed on the long side of the parking space 2, but Fig. 9 As shown, the barrier box 6 of the rear barrier is installed on the short side of the parking space 2, that is, the barrier box 6 of the rear barrier is installed next to the charging pile 1, or as shown in FIG. Fig.10 The device is shown installed in a corner of the parking space on the side of the charging pile.

[0132] The rear barrier has a display device 8, and the display device 8 can display different colors and patterns to represent specified information. For example, when a specified pattern is displayed, it represents the working status of the charging pile, such as available, unavailable, charging, or under maintenance. Therefore, the vehicle can obtain the working status or navigation information of the charging pile earlier and more conveniently than the above-mentioned embodiment 5. The rear barrier reduces the space occupied by fuel vehicles and charging vehicles in the charging parking space, and improves the operating efficiency of the charging station.

[0133] Embodiment seven:

[0134] The present invention further proposes that the display device 8 can also display a designated color to represent navigation information on the basis of the above-mentioned sixth or seventh embodiment. After the user completes the reservation, the designated color is assigned to the user, and the user only needs to drive the vehicle to find the target parking space displaying the designated color at the station. This can simplify the navigation information, or serve as an auxiliary navigation measure to further improve navigation efficiency.

[0135] The following is a system embodiment corresponding to the above method embodiment. This embodiment can be implemented in conjunction with the above embodiment. The relevant technical details mentioned in the above embodiment are still valid in this embodiment. In order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in the above embodiment.

[0136] like Fig.11 As shown, the present invention also proposes a vehicle guiding device B in a charging station based on scheduled charging, which includes:

[0137] The charging reservation module M1 is used to enable the station server to select idle charging piles in the charging station to form a charging pile candidate list, and the user selects a charging pile from the charging pile candidate list as a reserved charging pile through the client;

[0138] The entry guidance module M2 is used to enable the station server to pull the video streams of each camera in the charging station, and after identifying the reserved vehicle entering the charging station, obtain the position of the reserved vehicle through the video stream and the positioning algorithm; the station server plans the entry path from the position of the reserved vehicle to the reserved charging pile according to the internal road map of the charging station, and generates navigation information according to the entry path to guide the reserved vehicle to the target parking space where the reserved charging pile is located;

[0139] The vehicle energy replenishment module M3 is used to enable the station server to automatically unlock the ground lock of the target parking space or automatically lift the gate of the target parking space after recognizing that the reserved vehicle has arrived in the designated area of ​​the target parking space, and the reserved vehicle enters the target parking space;

[0140] The barrier pole of the barrier or the barrier pole of the ground lock is equipped with a display device, which is used to display the navigation information or the working status information of the charging pile; and the station server controls the display device to display the navigation information within a specified radius with the reserved vehicle position as the center according to the reserved vehicle position, so as to guide the reserved vehicle to the target parking space.

[0141] The vehicle guidance device in the charging station based on scheduled charging includes:

[0142] When the station server recognizes that the vehicle has finished charging, the station server plans a departure path from the location of the vehicle leaving the station after charging to the station exit location based on the internal road map of the station, and generates navigation information based on the departure path to guide the vehicle leaving the station to the exit of the charging station.

[0143] The vehicle guidance device in the charging station based on scheduled charging includes:

[0144] The internal road of the charging station is provided with underground lights, and the station server controls the underground lights to light up and display the navigation information, thereby guiding the vehicle to a designated reserved parking space or an empty parking space or an exit of the charging station; or

[0145] The charging station is provided with a speaker, and the station server controls the speaker to send out the navigation information to guide the vehicle to a designated reserved parking space or a vacant parking space or an exit of the charging station; or

[0146] The station server controls the client to send out the navigation information to guide the vehicle to a designated reserved parking space or a vacant parking space or an exit of the charging station.

The data acquisition device C is used to collect vehicle videos, and the information display device D is used to display the navigation information, charging pile working status information, etc. analyzed by the present invention.

[0150] The information display device D can sort and process the data output by the first electronic device A based on the information display mechanism to improve the readability of the data output by the first electronic device A. The information display mechanism can be manually preset, for example, the data output by the first electronic device A is visually displayed, which can be based on the display parameters and / or attributes set by the user. The display parameters can be, for example, the display data range, and the display attributes can be, for example, the display font, color, whether to scroll and play, etc. The user is presented with the key information specified by the user, such as route distance information, etc. The user can understand this information more promptly without having to access the secondary page or scroll the page, saving the user's operation. Or the information display mechanism can be an artificial intelligence AI display model, which can learn the user's key information based on the user's previous usage habits, such as viewing time, number of clicks, number of edits, etc., and then automatically present rich and necessary key information to the user.
