The precision/vertical parking solution is described using sensors as follows:
(1) A geomagnetic sensor: the intelligent central control built-in geomagnetic field sensor of the shared electric bicycle can measure the geomagnetic field, and under the condition of no magnetic interference, if the longitude, the latitude and the altitude of the local are known, the magnetic inclination angle and the magnetic declination angle can be calculated by using various geomagnetic field models after the direction of the geomagnetic field is measured, and then the polar north, the attitude and the like can be calculated, so that the direction of the head of the electric bicycle is determined, and the direction detection is realized;
(2) An NFC sensor: in order to standardize the parking of the shared electric bicycle, the NFC technology is used, whether the bicycle is parked in a fixed area or not is judged by intelligent central control, the fixed-point parking of the bicycle is realized, and the urban operation problems that the bicycle is parked in disorder and is placed in disorder and the like are effectively solved.
Description of the drawings: accuse built-in gyroscope sensor in intelligence is connected with the NFC card reader through RS485, realizes data communication, and the NFC card reader reads NFC passive label data, and data transmission controls in the intelligence, and accuse judges built-in gyroscope sensor data again in the intelligence, and radio communication uploads the supervision backstage, realizes that vehicle direction and position judge, carries out accurate vertical parking and judges.
The implementation steps are as follows: the intelligent central control (with a built-in gyroscope sensor) and the NFC card reader are installed on the shared electric bicycle and are in butt joint through an aviation connector line, so that data transmission is realized. Wherein the NFC reader is mounted at a foot pedal of the vehicle; installing an NFC passive tag on each parking space, and binding the tag with the position information of each parking space; when a vehicle enters a parking space, the NFC card reading module reads label information and sends the label information to the platform or an intelligent central control on the vehicle through the vehicle communication module, data processing is carried out, and meanwhile, the data are sent to the background monitoring platform; the supervision platform can judge the information and the parking position of the vehicle after receiving the label information and make an instruction on whether to allow locking the vehicle; the intelligent central control judges whether the parking position of the head of the vehicle meets the requirement of the parking space or not through a gyroscope sensor, and gives an instruction whether to allow locking the vehicle or not; through earth magnetism sensor and NFC card reader cooperation use, realize the accurate perpendicular parking of vehicle.
If the position that the electric bicycle was parked has earth magnetism to cover, the scheme that can select earth magnetism is as accurate parking, if do not have earth magnetism, can select to use the gyroscope. These two schemes that can all be used, the earth magnetism can realize simultaneously that the vehicle fixed point parks and accurate vertical parking, and the gyroscope can only realize accurate vertical parking. The geomagnetic cost is cheaper than that of a gyroscope, and the geomagnetic sensor has cost advantage. In the parking area, set up a earth magnetism emitter, can realize the parking area and cover, realize sharing electric bicycle fixed point parking. The fixed-point parking can not be realized by only relying on the gyroscope, and other technologies need to be matched. And the NFC sensor and the RFID sensor can be omitted due to geomagnetism.
