And when the change value is larger than the preset height difference, the processor acquires the parking position of the vehicle according to the geomagnetic sensor II, starts an advertisement push service mechanism corresponding to the parking position and sends advertisement push information II to the vehicle-mounted personnel. Therefore, the processor can accurately push the advertisement to the vehicle-mounted personnel, so that the utilization rate of electric energy resources can be further improved, the service life of equipment is prolonged under the unmanned condition of advertisement pushing, the pushing effect of the advertisement can be more obvious, and more vehicle-mounted personnel can receive the advertisement information.
In summary, compared with the existing advertisement pushing device in the parking lot, the advertisement pushing device applied to the large-scale parking charging station of the electric vehicle and the method thereof of the embodiment have the following advantages:
1. according to the advertisement pushing device applied to the large-scale parking charging station of the electric automobile, the geomagnetic sensor of the vehicle flow direction detection mechanism can detect the vehicle information of the corresponding circulation crossing, and the vehicle flow direction analysis module can integrate the circulation crossing where each vehicle passes according to the vehicle information, so that the flow direction information of each vehicle is obtained. A geomagnetic sensor II in a parking detection mechanism of the advertisement pushing device can detect whether vehicles exist on corresponding parking spaces or not, the existing vehicles are identified in type, an ultrasonic detection module in a get-off detection mechanism sends overtime waves to the vehicles and synchronously counts time, and therefore each ground clearance calculation module can calculate the ground clearance of the vehicles according to the timing time. Therefore, the processor can acquire 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 performs sequencing statistics on the vehicle flow on each circulation path according to the flow direction information, the circulation quantity of the vehicles reaches the circulation path of the preset vehicle flow to serve as an advertisement push path, and finally the advertisement push setting mechanism is driven to push advertisement push information I on the advertisement push path. Like this, this advertisement propelling movement information one can accurate propelling movement to demand customer in time, owing to carry out the advertisement propelling movement on the time slot and the route that the traffic flow is great, can make the propelling movement efficiency of advertisement promote by a wide margin moreover, and then can not the propelling movement advertisement when parking density and vehicle circulation quantity are not enough, avoid causing the electric energy waste because unmanned watching when the advertisement propelling movement, prolong advertising equipment's life to promote the propelling movement effect of advertisement.
2. This be applied to advertisement pusher of electric automobile large-scale parking charging station, its treater still judges the situation of change of terrain clearance, utilize the parking stall change after on-vehicle personnel get off and in time confirm on-vehicle personnel have got off, at this moment the treater orders about corresponding advertisement propelling movement service mechanism on to this on-vehicle personnel propelling movement advertisement propelling movement information two, can accurately with advertisement propelling movement to on-vehicle personnel, so can further improve the utilization ratio of electric energy resource, avoid advertisement propelling movement under unmanned condition, improve equipment's life, and can make the propelling movement effect of advertisement more obvious, make more on-vehicle personnel can receive advertisement information.
