The processing engine 112 may include a location information acquisition module 402, a movement distance acquisition module 404, a sending module 406, and a prompting module 408.
The location information acquisition module 402 may acquire location information of the wheelchair 130 at different points in time. In some embodiments, the wheelchair 130 may include one or more wheelchairs. In some embodiments, the location information of the wheelchair 130 may include one or more real-time location information. In some embodiments, the real-time location information may be acquired by a location system or location sensor mounted to the wheelchair 130. The real-time location information may include a real-time point in time, a geographic location where the wheelchair is located (e.g., a latitude and longitude where the wheelchair is located). In some embodiments, location information of the wheelchair 130 at different points in time may be obtained. For example, real-time location information of the wheelchair 130 at a preset point in time may be obtained. The preset time point may be stored in the processing engine 112 or the storage device 150. In some embodiments, the preset time point may be one or more time points determined at fixed time intervals. For example, a time point may be determined every 5 minutes, and the location information of the wheelchair 130 may be acquired according to a time point sequence generated by the time point. In some embodiments, the preset time point may be a fixed preset time point sequence (for example, a fixed position information acquisition time point may be preset, such as setting three time points of 6:10,6:15, and 6:17 as preset time points).
The movement distance acquisition module 404 may acquire at least one movement distance of the wheelchair 130 based on the location information of the wheelchair 130 at different points in time. The movement distance may be obtained based on position information of two different points in time of the wheelchair 130. For example, a vector may be determined based on geographic positions in the location information at two different time points, taking the geographic position in the location information at a first time point as a starting point and the geographic position in the location information at a second time point as an ending point. The length of the vector can be regarded as the distance of movement of the wheelchair in the two points in time. In some embodiments, the first time point and the second time point may be any two of the different time points. In some embodiments, at least one distance traveled by the wheelchair 130 determined based on the location information at any two different points in time may be obtained. In some embodiments, all travel distances of the wheelchair 130 determined based on the location information at any two different points in time may be obtained. In some embodiments, at least one moving distance of the wheelchair 130 determined based on the location information of each two adjacent time points of the different time points may be acquired.
The transmitting module 406 may transmit the position information of the wheelchair 130 at the current time point to the user terminal 140 when the at least one moving distance is greater than the preset threshold. In some embodiments, a preset threshold value for the movement distance may be preset. When the at least one moving distance is greater than the preset threshold, the location information of the wheelchair at the current time point may be transmitted to the user terminal 140. For example, the preset threshold may be preset to be 10 meters, and when a moving distance in the at least one moving distance is greater than the preset threshold, the position information of the wheelchair 130 at the current time point may be sent to the user terminal 140. In some embodiments, the user terminal 140 may display the location of the wheelchair 130 at the current time using text, sound, video, or any combination thereof. For example, the user terminal may show the location of the wheelchair 130 at the current time in the form of a location point on a map on a mobile phone interface. In some embodiments, the preset threshold may be a fixed value stored in the storage device 150. In some embodiments, the preset threshold may be a numerical value that is input or selected by the user at his or her discretion.
The prompting module 408 may send a prompting signal to the user terminal 140 when the at least one moving distance is greater than a preset prompting distance value. In some embodiments, the reminder distance value may be preset. In some embodiments, the user terminal 140 may prompt the user with a voice form, a ring prompt, a vibration prompt, or any combination thereof based on the prompt signal. For example, the user terminal 140 may remind the user that the movement distance of the wheelchair 130 is greater than the preset reminding distance value by broadcasting "the current movement distance of the wheelchair exceeds the range" through voice, or in a manner that the user terminal 140 vibrates, and the like. In some embodiments, the reminder distance value can be a fixed value stored in the storage device 150. In some embodiments, the reminder distance value may be a numerical value that is entered or selected by the user at his or her discretion.
It should be noted that the above description of the processing engine 112 is exemplary only and is not intended to limit the present invention within the scope of the illustrated embodiments. It will be understood by those skilled in the art that, having the benefit of the teachings of this system, various modifications and changes in the form and details of the application of the method and system described above may be made without departing from this concept, with any combination of the various modules or sub-systems being constructed to interface with other modules. For example, the moving distance obtaining module 404 and the sending module 406 may be the same module. For another example, a determining module may be added to determine whether at least one moving distance is greater than a preset threshold.
Fig. 5 is an exemplary flow chart illustrating transmitting location information according to some embodiments of the present disclosure.
At 510, location information of the wheelchair 130 at various points in time may be obtained. Operation 510 may be performed by location information acquisition module 402 in processing engine 112. In some embodiments, location information of the wheelchair 130 at time points determined at certain time intervals may be obtained. In some embodiments, location information of the wheelchair 130 at a preset point in time may be obtained. In some embodiments, the time interval may be a fixed length, such as 5 minutes, 10 minutes, and so forth. In some embodiments, the preset time point may be a fixed preset time point sequence (for example, a fixed position information acquisition time point may be preset, such as setting three time points of 6:10,6:15, and 6:17 as preset time points).
At 520, at least one distance traveled by the wheelchair may be obtained based on the location information of the wheelchair 130 at different points in time. Operation 520 may be performed by movement distance acquisition module 404 in processing engine 112. In some embodiments, the movement distance may be obtained based on location information of two different points in time of the wheelchair 130. For example, a vector may be determined based on geographic positions in the location information at two different time points, taking the geographic position in the location information at a first time point as a starting point and the geographic position in the location information at a second time point as an ending point. The length of the vector can be regarded as the distance of movement of the wheelchair in the two points in time. In some embodiments, the first time point and the second time point may be any two of the different time points. In some embodiments, at least one distance traveled by the wheelchair 130 determined based on the location information at any two different points in time may be obtained. In some embodiments, all travel distances of the wheelchair 130 determined based on the location information at any two different points in time may be obtained. In some embodiments, at least one moving distance of the wheelchair 130 determined based on the location information of each two adjacent time points of the different time points may be acquired.
In 530, when the at least one moving distance is greater than the preset threshold, the location information of the wheelchair at the current time point may be transmitted to the user terminal 140. Operation 530 may be performed by send module 406 in processing engine 112. For example, the preset threshold may be preset to be 10 meters, and when a moving distance in the at least one moving distance is greater than the preset threshold, the position information of the wheelchair 130 at the current time point may be sent to the user terminal 140. In some embodiments, the preset threshold may be a fixed value stored in the storage device 150. In some embodiments, the preset threshold may be a numerical value that is input or selected by the user at his or her discretion.
In some embodiments, the user terminal 140 may display the location of the wheelchair 130 at the current time using text, sound, video, or any combination thereof. For example, the user terminal may show the location of the wheelchair 130 at the current time in the form of a location point on a map on a mobile phone interface.
It should be noted that the above description of the flowchart for sending the location information to the ue 140 is only for convenience of description and is not intended to limit the present invention within the scope of the illustrated embodiments. It will be apparent to those skilled in the art having the benefit of this disclosure that many modifications and variations are possible in the field of use and details of the methods and systems described above without departing from the principles thereof. For example, operation 530 may be performed after operation 520 or may be performed simultaneously. At least one operation may be added or deleted in flow 500. For example, an operation of acquiring a preset threshold value in the storage 150 may be added.
FIG. 6 is an exemplary flow chart illustrating sending a cue signal according to some embodiments of the present disclosure.
At 610, a reminder distance value may be preset. In some embodiments, the reminder distance value can be a fixed value stored in the storage device 150. For example, the reminder distance value may be a fixed value of 5 meters, 10 meters, etc. In some embodiments, the reminder distance value may be a numerical value that is entered or selected by the user at his or her discretion. For example, the user may enter a reminder distance value such as 11 meters, 15 meters, etc. by himself. For another example, the user may select from the fixed values provided by the ue 140, for example, the ue 140 may provide a value range of 10 m to 15 m for the user to select.
At 620, a cue signal may be transmitted when at least one of the travel distances is greater than the alert distance value. In some embodiments, the user terminal 140 may prompt the user with a voice form, a ring prompt, a vibration prompt, or any combination thereof based on the prompt signal. For example, the user terminal 140 may remind the user that the movement distance of the wheelchair 130 is greater than the preset reminding distance value by broadcasting "the current movement distance of the wheelchair exceeds the range" through voice, or in a manner that the user terminal 140 vibrates, and the like.
It should be noted that the above description of the flowchart for sending the prompt signal to the ue 140 is only for convenience of description, and is not intended to limit the scope of the present invention to the illustrated embodiments. It will be apparent to those skilled in the art having the benefit of this disclosure that many modifications and variations are possible in the field of use and details of the methods and systems described above without departing from the principles thereof. For example, at least one operation may be added or deleted in flow 620. For example, an operation of storing the alert distance in the storage 150 may be added.
