It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

Example 1

Referring to FIG. 1 , this embodiment provides an advertisement push device applied to a large parking charging station of an electric vehicle, and the advertisement push device is used to provide an advertisement push service to on-board personnel in a parking lot. Wherein, the advertisement push device includes a vehicle flow direction detection mechanism, a parking detection mechanism, a get-off detection mechanism, an advertisement push service platform and a processor. The traffic direction detection agency collects and detects the flow direction information of vehicles in the parking lot, the parking detection agency can collect the parking information in the parking lot, and the alighting detection agency can collect the alighting information of the on-board personnel of each parked vehicle, while the advertising push service platform Relevant advertisement information can be pushed to the on-board personnel or circulation vehicles, and the processor can integrate and analyze the collected information, so as to purposefully push advertisements at locations with large customer traffic, which significantly enhances the effect of advertisement push.

The vehicle flow direction detection mechanism includes a vehicle flow direction analysis module and a plurality of geomagnetic sensors. The plurality of geomagnetic sensors correspond to the plurality of circulation intersections of the parking lot, and each geomagnetic sensor is installed at the corresponding circulation intersection and is used to detect vehicle information passing through the corresponding circulation intersection. The geomagnetic sensor can be used to detect the presence of vehicles and identify the vehicle type. It uses the characteristics determined by the distribution of the earth's magnetic field. When the vehicle passes through, the magnetic field distribution will change and the resistance characteristics inside the sensor will change to measure the magnetic field change. Compared with the commonly used geomagnetic coil detector, the geomagnetic sensor has the advantages of small installation size, high sensitivity, small construction amount, long service life and less damage to the road surface. The vehicle flow direction analysis module is used to obtain the vehicle flow direction information according to the vehicle information generated by the same vehicle. Specifically, the vehicle flow direction analysis module will count all the circulation intersections passed by the same vehicle in a period of time, and connect these intersections into a circulation path. Of course, these circulation intersections can also be combined with multiple preset circulation paths. By comparison, the circulation path with the most circulation intersections is selected as the actual circulation path of the vehicle. During analysis, the vehicle flow direction analysis module needs to integrate the detection information of all geomagnetic sensors, classify and count the vehicles according to the vehicle information, and perform separate statistics for each vehicle according to the time line. In addition, in order to accurately identify vehicles of the same model, in some special cases, the vehicle flow direction detection mechanism may further include multiple license plate recognition modules, and the multiple license plate recognition modules correspond to multiple geomagnetic sensors respectively. Each license plate recognition module is used to identify the license plate of the vehicle at the corresponding circulation intersection, so that the license plate number of the same model can be accurately determined. Of course, the license plate recognition module can recognize two vehicles of the same model after the geomagnetic sensor recognizes start up. The license plate recognition module can use a camera, which takes pictures of the vehicle to obtain image information at the location of the vehicle license plate, then extracts the license plate outline and character features, and finally converts the character features into the vehicle's license plate number.

The parking detection mechanism includes a plurality of second geomagnetic sensors, and the plurality of second geomagnetic sensors respectively correspond to a plurality of parking spaces in the parking lot. Each second geomagnetic sensor is installed on the corresponding parking space, and is used to detect whether there is a vehicle in the corresponding parking space, and identify the type of the vehicle when there is a vehicle in the corresponding parking space. The second geomagnetic sensor can use the same type of sensor as the first geomagnetic sensor, which can accurately identify the vehicle in the parking space. When the driver parks the vehicle in the parking space, the second geomagnetic sensor will automatically sense the parking time of the vehicle and transmit the time to the relay station. At the same time, since the second geomagnetic sensor has a camera function, it can also collect the license plate information of the vehicle.

The getting-off detection mechanism includes a plurality of getting-off detecting components, the plurality of getting-off detecting components are respectively corresponding to a plurality of parking spaces, and each getting-off detecting component includes an ultrasonic detecting module and a ground clearance calculating module. Each ultrasonic detection module is installed on the corresponding parking space to transmit ultrasonic waves to the vehicle and synchronize timing. Each ground clearance calculation module is used to calculate the ground clearance height of the vehicle from the corresponding parking space according to the timing time of the corresponding ultrasonic detection module. Since the ultrasonic wave will be reflected back after it is transmitted to the chassis of the vehicle, and because the propagation speed of the ultrasonic wave in the air is constant, the corresponding propagation distance can be calculated, and further the height above the ground can be calculated. In this embodiment, the timing time is the time interval from when the ultrasonic detection module transmits ultrasonic waves to the vehicle until the receiver receives the same ultrasonic wave. The transmitter and the receiver are located in the same vertical direction of the chassis of the vehicle. Therefore, the calculation formula of each ground clearance calculation module to calculate the ground clearance is:

Among them, H is the height above the ground, C is the ultrasonic propagation speed, and T is the timing time.

The second advertisement push information includes the location of the rest room in the parking lot, the scope of products and services, and the advertisement in the station, which can guide the vehicle and facilitate the advertisement to the customers. In this embodiment, the advertisement push service mechanism may include a guide display screen and a voice module. The guidance display screen is installed near the corresponding parking space, for example, it can be installed on the front and rear sides of the parking space, so that the advertisement can be directly pushed to the passengers in the vehicle when the vehicle is parked. The guide display screen is used to display the second advertisement push information, and can also be used to display the charging information of the vehicle located in the corresponding parking space. The voice module is synchronized with the guidance display, which can push out the voice information in the advertisement, and can also send out relevant prompt information when the battery is fully charged.

The processor is used to first obtain the parking quantity of the parking lot according to the detection information of all the second geomagnetic sensors, then calculate the parking density of the parking lot, and finally judge whether the parking density reaches a preset vehicle density. When the parking density reaches the preset vehicle density, the processor first counts and sorts the number of vehicles in circulation on each circulation path according to the flow direction information of each vehicle, and then selects at least one circulation path where the number of vehicles in circulation reaches a preset traffic flow As an advertisement push path, and finally drive the advertisement push setting agency to push advertisement push information 1 on the advertisement push path. In this way, the advertisement push information can be accurately and timely pushed to the customers who need it, and because the advertisement push is carried out during the period and on the route with relatively large traffic flow, the advertisement push efficiency can be greatly improved, while the parking density and the number of vehicles in circulation are insufficient. When the advertisement is pushed, the advertisement will not be pushed, so as to avoid the waste of electric energy caused by no one watching when the advertisement is pushed, and prolong the service life of the advertisement equipment, thereby improving the push effect of the advertisement.

The processor is further configured to determine whether the change value of the height above the ground is greater than a preset height difference when there is a vehicle in a parking space. When the change value is greater than the preset height difference, the processor obtains the parking position of the vehicle according to the second geomagnetic sensor, and activates an advertisement push service agency corresponding to the parking position to send advertisement push information II to the vehicle personnel. In this way, the processor can accurately push the advertisement to the vehicle personnel, which can further improve the utilization rate of electric energy resources, avoid the advertisement push in the case of no one, improve the service life of the equipment, and make the advertisement push effect more obvious. , so that more on-board personnel can receive advertising information.

To sum up, compared with the existing advertisement push device in the parking lot, the advertisement push device and the method thereof applied to the large-scale electric vehicle parking charging station of the present embodiment have the following advantages:

1. The advertisement push device applied to the large-scale parking and charging station of electric vehicles, the geomagnetic sensor of the vehicle flow direction detection mechanism can detect the vehicle information of the corresponding circulation intersection, and the vehicle flow direction analysis module can be based on the vehicle information.

The second geomagnetic sensor in the parking detection mechanism of the advertisement push device can detect whether there is a vehicle in the corresponding parking space, and perform vehicle type identification for the existing vehicle, while the ultrasonic detection module in the get-off detection mechanism sends a timeout wave to the vehicle and synchronizes the timing. , so that each ground clearance calculation module can calculate the ground clearance of the vehicle according to the timing time. In this way, the processor can obtain the parking quantity of the parking lot according to the detection information of the parking detection mechanism, further calculate the parking density, and finally judge whether the parking density reaches the preset vehicle density. When the parking density reaches the preset vehicle density, the processor sorts and counts the traffic flow on each circulation path according to the flow direction information, and uses the circulation path where the number of vehicles in circulation reaches the preset traffic flow rate as the advertisement push path, and finally drives the advertisement push Set the agency to push advertisement push information 1 on the advertisement push path. In this way, the advertisement push information can be accurately and timely pushed to the customers who need it, and because the advertisement push is carried out during the period and on the route with relatively large traffic flow, the advertisement push efficiency can be greatly improved, while the parking density and the number of vehicles in circulation are insufficient. When the advertisement is pushed, the advertisement will not be pushed, so as to avoid the waste of electric energy caused by no one watching when the advertisement is pushed, and prolong the service life of the advertisement equipment, thereby improving the push effect of the advertisement.

Example 2

The calculation formula of each ground clearance calculation module to calculate the ground clearance is:

Among them, H is the height above the ground, C is the ultrasonic propagation speed, T is the timing time, and D is the distance between the transmitting end and the receiving end of the ultrasonic detection module. The propagation of ultrasonic waves is similar to the propagation of sound waves, and its propagation speed is not very large. Generally, the propagation speed of sound waves is taken, that is, the propagation speed in the air at 15 degrees Celsius is 340m/s. Of course, the propagation speed of ultrasonic waves is positively correlated with temperature, and relevant parameters can be set in the actual calculation process. However, since the temperature does not change much in a short period of time, especially during a single ultrasonic time measurement, it can be considered that the propagation speed is a fixed value, which does not unduly affect the accuracy of the height above the ground in this embodiment. In practice, the value of distance D is very small relative to CT, and in some embodiments, the value of distance D may be taken to be zero.

Y ₁ =y ₁ -y ₂

In the formula, y ₁ is the number of vehicles detected by the vehicle flow direction detection mechanism within a preset time, y ₂ is the number of vehicles detected by the vehicle flow direction detection mechanism and the parking detection mechanism within a preset time period, and satisfies: Y ₂ =y ₂ .
