The thermal infrared human body sensor is used for detecting whether circulating personnel exist on the corresponding circulating path.

The processor firstly counts the total number of circulating personnel in the parking lot according to the detection information of each thermal infrared human body sensor, and then judges whether the total number of the circulating personnel is larger than a preset customer number. When the total number of the circulating personnel is larger than the preset number of the clients, the processor drives the advertisement push setting mechanism on the circulating route of the circulating personnel to set advertisement push information I. The processor is further used for counting the number of the circulation staff paths on each circulation path, sequencing the number of the circulation staff paths, and finally taking the circulation path with the largest number of the circulation staff paths as a setting area of the advertisement pushing setting mechanism.

Example 5

The embodiment provides a large parking charging field of an electric automobile with intelligent fire-fighting treatment, and the processor is described in detail on the basis of the embodiment 1. The processor comprises a path simulation module, a traveling path length calculation module and a sequencing display module.

The path simulation module is used for acquiring the position information of all the free parking spaces and simulating the traveling path from the entrance barrier to each free parking space. The position information of these idle parking stalls can acquire through earth magnetism sensor, and of course, these position information also can acquire through idle electric pile of filling, can also confirm through special position detection module. The traveling path actually has many paths, generally speaking, a parking lot has many roads, and the combination of the roads has many paths, so that a route from a certain vacant parking space to the entrance barrier has many paths.

The travel path length calculating module is used for calculating the length of each travel path. The lengths of the traveling paths are different from each other, and the lengths directly determine the distance that the electric vehicle to be charged needs to travel, and meanwhile, in the process, the energy of the driver is greatly consumed, the electric quantity of the electric vehicle is consumed, especially when the electric vehicle needs to be charged, the electric quantity of the electric vehicle is possibly insufficient, and if the electric vehicle needs to travel along the traveling path, the electric vehicle is possibly dead, and the operation efficiency of the parking lot is affected.

The sequencing display module is used for sequencing the path lengths in a sequence from small to large and displaying the corresponding idle parking spaces on the intelligent guide screen in a sequence according to the sequencing of the path lengths. Like this, make electric automobile can reach idle parking stall in the shortest time and charge on the one hand, shorten the travel time of vehicle, the energy saving, on the other hand is owing to plan the route of marcing, to some drivers who are not familiar with the parking area environment, is equivalent to providing navigation service for it to promote the service level that parks and charges, make the operation in parking area more smooth, also alleviateed driver's intensity of labour simultaneously.

The path simulation module comprises a preset unit, a segmentation unit, a width judgment unit, a path definition unit to be determined, a path length calculation unit to be determined and a traveling path determination unit. The presetting unit is used for presetting all parking spaces in a simulation map. The size proportion of the parking lot and the simulation map is fixed, and each parking space corresponds to one simulation parking space. The simulation map is actually a reduced map of the parking lot, which is similar to various mobile phone maps used in daily life, and can reduce each position and equipment in the parking lot according to a certain reduction scale and generate a corresponding two-dimensional map.

The dividing unit is used for dividing a connecting area of the simulated parking space corresponding to the idle parking space and the entrance barrier into a plurality of rectangular areas with wide sides connected, and calculating the width of each rectangular area. The occupied parking spaces and other protruding parts of the parking lot are not in the connecting area. These rectangular regions are actually components of a route, and if the width of one of the rectangular regions is too small, the electric vehicle cannot pass through the rectangular regions, so that the width of each rectangular region needs to be calculated.

The width judging unit is used for judging whether the width of the rectangular area is larger than the vehicle simulation width of the electric automobile in the simulation map. When any point on the curve is positioned below the straight line, the rectangular region corresponding to the point does not meet the condition, namely the width is smaller than the vehicle simulation width, and the electric automobile cannot pass through the rectangular region.

The path to be determined defining unit is used for taking the connecting areas of which the widths of all the rectangular areas are larger than the vehicle simulation width as a path to be determined. When the width of all the rectangular areas is larger than the vehicle simulation width, the connection area can be used for the electric vehicle to pass through, and accordingly, the connection area is actually a vehicle passing road.

The path length to be determined calculation unit is used for calculating the lengths of all paths to be determined. The purpose of calculating the length of the path to be determined here is to be able to determine the shortest path and thus optimize the path selection.

The travel path determining unit is used for selecting the path to be determined with the shortest length as the travel path. Therefore, the shortest passing path can be provided for the electric automobile, so that the electric automobile can reach an idle parking space in the shortest time to be charged, and the quick charging of the electric automobile is realized.
