At present, in order to comply with the requirement of urban management, each sharing bicycle enterprise judges whether the sharing bicycle is parked in a parking site by adopting a satellite positioning technical means. Specifically, the shared bicycle is provided with a satellite positioning device, and for the technical problem of judging whether the shared bicycle is parked in a parking station, the existing technical scheme is to judge the position of the shared bicycle by using a satellite positioning technology and compare the position of the shared bicycle with the range of the parking station, so as to judge whether the shared bicycle is parked in the parking station.

Detailed Description
The following detailed description of the embodiments of the present invention will be provided with reference to the drawings and examples, so that how to apply the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented. It should be noted that, as long as there is no conflict, the embodiments and the features of the embodiments of the present invention may be combined with each other, and the technical solutions formed are within the scope of the present invention.
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details or with other methods described herein.
Fig. 1 shows an exemplary application scenario of the present invention, which takes an intersection as a parking site. A parking station is provided within 30 meters of the intersection, in which a plurality of passive radio beacon devices 100 are provided. The communication ranges of these passive radio beacon devices 100 combine with each other to cover the entire parking station, thereby identifying the parking station range.
Example one
Fig. 2 is a schematic diagram illustrating a passive radio beacon system according to a first embodiment of the present invention.
As shown in fig. 2, the system is primarily comprised of a passive radio beacon device 100 and a scanning communication device 200.
The passive radio beacon apparatus 100 mainly includes: an antenna 101, a transmitter 102, a controller 103 and a memory 104, and a power supply 105, wherein:
the transmitter 102 is used for modulating and power-amplifying the code output by the controller 103 and transmitting the modulated code through the antenna 101.
The memory 104 is used to store parameter information about the parking station and the passive radio beacon device;
the controller 103 is connected with the memory 104 and the transmitter 102, and is used for controlling the transmitter 102 to transmit the broadcast signal through the antenna 101 according to the parameter information of the passive radio beacon device in the memory 104;
a power supply 105 that provides power support for the various functional modules of the passive radio beacon device 100.
Specifically, in city management, a parking station is not always in one state. In consideration of full utilization of resources, during one period of the day, the city manager will classify the parking stop as a completely forbidden state, and during another period of the day, the city manager will classify the parking stop as a partially vehicle-stoppable state or a completely stoppable state, so as to achieve the purpose of improving the utilization rate of the urban resources. Thus, the passive radio beacon device 100 of the present invention has built-in controller 103 and memory 104. The controller 103 may modify the parameter information of the parking station stored in the memory 104 according to instruction information received through a debugging interface (not shown in the figure), for example. For example, the parameter information of the parking stations stored in the memory 104 may be modified according to the time or the date, or a plurality of sets of parameter information may be pre-stored, so that the passive radio beacon device 100 can change the range of the parking station identified by the passive radio beacon device, the type of vehicle allowed to be parked, and the time period allowed to be parked according to the time or the date, thereby achieving the purpose of improving the utilization rate of urban resources.
In addition, the memory 104 of the passive radio beacon device 100 also stores therein parameter information of the passive radio beacon device, such as the frequency, power and time at which the passive radio beacon device transmits the beacon signal, and the number and location information of the passive radio beacon device. Likewise, the controller 103 may modify the parameter information of the parking station stored in the memory 104 according to instruction information received, for example, through a debugging interface (not shown in the figure). For example, by adjusting the transmission power of the passive radio beacon device 100, the size of the parking station covered by the communication range of the passive radio beacon device 100 is precisely controlled.
In some passive radio beacon devices 100, the antenna 101 may be configured as a omnidirectional antenna so as to transmit broadcast signals in all directions, thereby achieving the technical effects of covering the passive radio beacon device 100 as a center and obtaining as large a coverage area as possible; in other passive radio beacon devices 100, the antenna 101 may be a directional antenna to transmit a broadcast signal over an angular sector, thereby achieving the technical effect of clearly controlling the boundaries of the parking station. Furthermore, the antenna 101 may also be arranged as a phased array antenna, so that the control range of the parking station can be determined more flexibly.
On the basis of controlling the distance of the communication range by the parameter information of the passive radio beacon device 100 itself and controlling the shape of the communication range by the antenna 101 of the passive radio beacon device 100, the passive radio beacon device 100 can accurately control the shape and size of the parking station, thereby achieving the advantageous effect of accurately identifying the parking station.
In implementation, the scanning communication device 200 may be disposed on the target vehicle or on a mobile terminal interacting with the target vehicle. Specifically, the scanning communication device 200 includes a control module, a scanning module, a communication module, and a prompting module (not shown in the figure). Wherein:
a control module for outputting a scanning instruction when it is determined that the user wants to park the target vehicle, outputting a prompt instruction when it is recognized that a broadcast signal transmitted by the passive radio beacon device 100 exists around, and outputting a reporting instruction when it is determined that the user parks the target vehicle at a parking station identified by the passive radio beacon device according to a distance between the target vehicle and the passive radio beacon device;
a scanning module, connected to the control module, for starting signal scanning according to the scanning instruction output by the control module to identify whether there is a broadcast signal transmitted by the passive radio beacon device 100 around;
the prompting module is connected with the control module and used for generating prompting information according to the prompting instruction output by the control module and informing a user whether a target vehicle can be parked or not;
and the communication module is connected with the control module and used for reporting the parking behavior of the user to the management system according to the reporting instruction output by the control module or reporting the broadcast signal received by the scanning module and/or the information of the scanning communication device to the management system.
Generally, when the scanning communication device 200 is installed on the target vehicle, the control module of the scanning communication device 200 preferably determines whether the user has an intention to park the target vehicle according to the vehicle speed collected by the vehicle sensor and the duration of the wheel static state (e.g., exceeding a set time threshold) and/or the closing action of the lock, and then determines whether to trigger the scanning module to activate the signal scanning function. When the scanning communication device 200 is disposed on a mobile terminal, the control module of the scanning communication device 200 may trigger the scanning module to initiate the signal scanning function directly upon a user request (e.g., by clicking a button of the mobile terminal application software). Of course, the two methods may be combined and used, and are not limited herein.
In the present embodiment, the passive radio beacon apparatus 100 and the scanning communication apparatus 200 are both low power consumption near field communication apparatuses. Specifically, since the communication device using the bluetooth low energy communication protocol has the advantages of wide application, small influence on the environment, stable performance, and the like, the communication device preferentially using the bluetooth low energy communication protocol according to the present invention realizes the communication functions of the passive radio beacon device 100 and the scanning communication device 200 according to the present invention. Of course, other communication protocols may be used to implement the communication functions of the passive radio beacon device 100 and the scanning communication device 200 of the present invention, such as: BLE, WIFI, ZigBee, Rola, Beacon, NFC, RFID, ISO14443-TYPEB and 433MHz and 2.4GHz communication protocols based on custom protocols. These should fall within the scope of the present invention.
In this embodiment, the prompting module at least has a voice prompting function.
Example two
Fig. 3 shows an exemplary process of the system for identifying a parking station based on a passive radio beacon. In this embodiment, the passive radio beacon device 100 may transmit the broadcast signal at different powers for different time periods to achieve the technical effect of saving energy consumption. The scanning communication device 200 may be located on either the target vehicle or a mobile terminal interacting with the target vehicle.
In this embodiment, whether the user has an intention to park the target vehicle is determined according to the vehicle speed information (e.g., less than a given vehicle speed threshold) collected by the sensor on the target vehicle and the duration of the wheel stationary state (e.g., exceeding a set time threshold), and when it is determined that the user has the intention to park the target vehicle, the scanning module of the scanning communication device 200 activates the signal scanning function to identify whether the broadcast signal transmitted by the passive radio beacon device 100 exists around the target vehicle. The broadcast signal includes the number and location information of the passive radio beacon device 100.
When the broadcast signal transmitted by the passive radio beacon device 100 is scanned, the prompt module of the scanning communication device 200 sends a corresponding prompt message to the user to inform the user whether parking of the target vehicle is allowed. Further, the user can be simultaneously informed of the parking site range, the type of the parkable vehicle, and the parkable time period.
Of course, if the broadcast signal transmitted by the passive radio beacon device 100 is not scanned, it indicates that the target vehicle is not in the parking station and the target vehicle may not be parked there.
In this embodiment, after the scanning communication device 200 sends the prompt message allowing the parking of the target vehicle to the user, if it is determined that the user parks the target vehicle at the parking station where the passive radio beacon device 100 is located, the parking behavior of the user needs to be further reported to the management system, or the information of the passive radio beacon device 100 needs to be reported, so as to make a corresponding parking record or parking determination for the user.
Specifically, when the user turns off the lock of the target vehicle, the scanning communication device 200 acquires the real-time location information of the target vehicle, compares the real-time location information with the previously acquired location information of the passive radio beacon device to analyze the distance between the target vehicle and the passive radio beacon device, and then determines whether the user parks the target vehicle at a parking station identified by the passive radio beacon device according to whether the distance is smaller than, for example, the radius of the parking station (or other parameter indicative of the range of the parking station). When it is determined that the user parks the target vehicle at the parking station identified by the passive radio beacon device 100 according to the state of the parking station, the scanning communication device 200 reports the parking behavior of the user to the management system to record the parking of the user.
In addition, after acquiring the real-time location information of the target vehicle, the scanning communication device 200 may also send the real-time location information to the management system, and the management system may determine and record the parking behavior of the user and feed the parking behavior back to the scanning communication device 200.
In this embodiment, after the scanning communication device 200 sends the prompt message allowing the target vehicle to park to the user, if it is determined that the user does not park the target vehicle at the parking site where the passive radio beacon device 100 is located, the parking behavior of the user needs to be further reported to the management system, so as to give corresponding reward to the user.
Specifically, after the lock of the target vehicle is closed, whether the scanning communication device can receive the broadcast signal transmitted by the passive radio beacon device or not is judged at a given time threshold; if the scanning communication device can receive the broadcast signal transmitted by the passive radio beacon device at the given time threshold, the fact that the user parks the target vehicle at the target station identified by the passive radio beacon device is judged, and the scanning communication device reports the parking behavior of the user to the management system so as to give corresponding rewards to the user.
It should be noted that, although the embodiments of the present invention are described above, the descriptions are only for the convenience of understanding the present invention and are not intended to limit the present invention. Thus, it will be apparent to persons skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as disclosed, and the scope of the invention as defined in the appended claims is to be accorded the full scope of the invention.
