The invention relates to the technical field of unmanned driving, and provides a parking point determining method and device, computer equipment and a storage medium. The method comprises the steps that a parking area is generated according to a first parking point, then map attributes and order attributes are obtained, a plurality of second parking points are selected in the parking area according to the map attributes and the order attributes, the second parking points are different from the first parking point, and finally the optimal parking point is determined from the second parking points. According to the scheme provided by the invention, when the vehicle is sensed not to reach the first parking point originally designated by the passenger, a plurality of second parking points different from the first parking point are selected from a parking area generated based on the first parking point according to the map attributes and the order attributes, and finally an optimal parkingpoint is determined from the second parking points, so that the vehicle can be smoothly parked at the optimal parking point to pick up passengers.

The invention belongs to the technical field of intelligent transportation, and particularly relates to a traffic flow detection system and method based on geomagnetic sensing spikes. The system comprises a plurality of spikes which are pre-embedded in a road section in groups according to the cross section of a road, and each group of spikes comprise lamplight induction type spikes arranged on the boundaries of the two sides of each channel of the road section and geomagnetic sensing type spikes arranged in the middle of each channel and used for sensing passing of vehicles; each group of spikes are connected into a gateway of a server system through a repeater matched with the spikes, each repeater is connected with the gateway in a time-sharing sending mode, and the repeater calculatesthe vehicle speed, the flow and the vehicle type according to the sensing data of the geomagnetic sensing type spikes of the corresponding group and uploads the vehicle speed, the flow and the vehicletype to the gateway in a packaging mode.

The invention discloses a parking detection method for preventing fire-fighting hidden dangers. The parking detection method comprises the steps of: detecting whether vehicle interference exists or not by means of a magnetic sensor, generating a stable stepped magnetic field variable quantity after the vehicle interference when detecting that vehicles interfere with one another, and transmitting the changed magnetic field data to an MCU; activating a microwave sensor for detection when the MCU receives the stable stepped variable quantity of a magnetic field value, receiving data of the microwave sensor by means of the MCU, analyzing whether the distance of an obstacle conforms to a chassis height range of the vehicle or not, and if so, determining that vehicle interference exists; and determining whether the magnetic sensor and the microwave sensor both detect vehicle interference or not, and starting an illegal parking detection mode if the magnetic sensor and the microwave sensor both detect vehicle interference. According to the parking detection method, multi-sensor combined judgment is adopted for parking detection, the system power consumption is saved, the parking detectionaccuracy rate is improved, the judgment result controls the voice broadcast module by means of a wireless network, the purpose of preventing illegal occupation of a fire fighting access in real timecan be achieved, and illegal parking events are effectively prevented.

Parking detection method for preventing fire-fighting hidden dangers

The present invention discloses a parking detection system and method for preventing from fire hazards. The parking detection system comprises at least one parking detection device, at least one voicebroadcast device and a control center; the control center is connected with each parking detection device and each voice broadcast device through a wireless communication network; the control centercontrols the parking monitoring devices and the voice broadcast devices of a plurality of no-parking regions; in the same no-parking region, one voice broadcast device corresponds to one or more thanparking detection devices; and each parking detection device comprises a first microprocessor MCU, a magnetic sensor, a microwave sensor and a first wireless communication module. Through combinationof multiple sensors, parking detection is determined to save system power consumption and improve the parking detection accuracy, the determination result is employed to control the voice broadcast modules through a wireless network so as to achieve the purpose of preventing the fire channel from violation and effectively avoid generation of parking violation events.
