The parking guidance system finds out all parking lots which have free parking spaces and the remaining rental time of the free parking spaces exceeds the expected parking time within the jurisdiction range of the parking guidance system; and sending the found position identifications of all the parking lots to the communication equipment, so that a driver of a vehicle where the communication equipment is located selects any parking lot from the found all the parking lots as a target parking lot according to the found position identifications of all the parking lots.
In the embodiment of the invention, each free parking space can be rented according to time, namely, each free parking space can be provided with a renting time length (for example, 08: 30-18: 00). For example, after a driver drives a car at 8 o' clock in the morning and goes to work, the driver may rent the free parking space, and the driver may report a rental period (e.g., 08: 30 to 18: 00) set by the driver for the free parking space to the parking guidance system.
In the embodiment of the present invention, the position identifier of the parking lot may include information used for identifying a certain place of the parking lot, such as a physical position coordinate of the parking lot, a landmark position of the parking lot, and the like.
103. The parking guidance system inquires weather information with preset duration corresponding to the target parking lot and sends the weather information to the communication terminal, so that a driver of a vehicle where the communication terminal is located can determine whether an external guidance path needs to be generated or not according to the weather information.
In the embodiment of the present invention, the manner for the parking guidance system to query the weather information with the preset duration corresponding to the target parking lot and issue the weather information to the communication terminal may be:
the parking guidance system judges whether the current work load of the parking guidance system exceeds the work load appointed by the parking guidance system, if not, a weather information query request comprising a target parking lot position is initiated to a weather service platform corresponding to a weather information query port through the weather information query port; receiving weather information of preset duration (such as 1 day) corresponding to the target parking lot, returned by the weather service platform through the weather information query port; and the parking guidance system issues the weather information of the preset time length corresponding to the target parking lot to the communication equipment.
By implementing the embodiment, the driver can predict the weather information of the preset duration (such as 1 day) corresponding to the target parking lot in advance, so that vehicle protection preparation during parking can be well made, and the vehicle is prevented from being damaged by severe weather.
104. And when the indication information reported by the communication terminal indicates that an external guide path needs to be generated, the parking guide system generates an external guide path between the entrance position of the target parking lot and the current vehicle position, and sends the external guide path and the position information of the target parking lot in the target parking lot to the communication equipment for parking guide, wherein the target parking lot is any free parking lot with the residual rental time length exceeding the expected parking time length.
Referring to fig. 2, fig. 2 is a schematic view of an interface of an external guiding path and a target parking space displayed by a communication device according to an embodiment of the present invention. As shown in fig. 2, a solid line represents an external guide path, and a dotted-line frame represents position information of a target parking space in a target parking lot. The driver can drive the vehicle to the target parking space of the target parking lot to park according to the external guide path displayed by the communication equipment and the position information of the target parking space in the target parking lot.
It can be seen that, by implementing the method described in fig. 1, the vehicle can be guided to the parking space suitable for the expected parking duration of the driver, so that the utilization rate of the parking space can be improved.
It can be seen that the method described in fig. 1 can be implemented to avoid driving accidents due to emotional instability or eye fatigue of the driver.
It can be seen that the method described in fig. 1 can be implemented to avoid the large power consumption caused by the communication device directly communicating with the parking guidance system.
Therefore, by implementing the method described in fig. 1, the driver can predict the weather information of the preset duration corresponding to the parking lot in advance, and prepare for vehicle protection during parking, so as to prevent the vehicle from being damaged by severe weather.
