The control module 340 may control components and/or modules in the smart wheelchair system 100. In some embodiments, the control module 340 may determine one or more control parameters based on the alarm information and/or emergency response determined by the determination module 330. The control parameters may be sent to the wheelchair body 250 in the smart wheelchair 110 to control the movement of the smart wheelchair. For example, if the current physiological value or values of the user are not within the preset safety threshold, the control module 340 may control the backrest 112 of the wheelchair body 250 to tilt backward and maintain the seat 111 horizontal according to the emergency response (e.g., flat) determined by the determination module 330, so that the user lies down. In some embodiments, the control module 340 may receive a command from the user device 130. The commands may be provided by a user and one or more components in the smart wheelchair 110 adjusted according to the commands.
It should be noted that the block diagram of the processor in the exemplary intelligent wheelchair depicted in FIG. 3 is for convenience of description only and should not limit the scope of the present application to the illustrated embodiments. It will be understood by those skilled in the art that, having the benefit of the teachings of the present application, numerous modifications and variations can be made in the form and details of the above-described methods and systems without departing from such teachings, and such modifications and variations will still fall within the scope of the above-described. For example, a processor may include one or more other modules.
FIG. 4 is a flow chart illustrating control of the intelligent wheelchair system according to some embodiments of the present application. The steps 400 described in fig. 4 may be performed by the processor 220 in the smart wheelchair 110 according to instructions stored in the memory 230.
At step 410, the processor 220 (e.g., the acquisition module 310) may acquire physiological information of the user from the one or more sensors 210 in real-time or non-real-time. The one or more sensors 210 may include medical monitoring sensors. The medical monitoring sensor may be used to monitor and/or record physiological information of a user. The medical monitoring sensor may include various devices, for example, a blood pressure measuring device, an electrocardiographic monitoring device, a blood measuring device, a pulse wave detector, a brain wave monitor, a heart rate detector, a blood oxygen detector, a respiration detector, or a body temperature detector. Accordingly, the physiological information may include, but is not limited to, blood pressure information, electrocardiogram information, blood information, pulse information, brain wave information, heart rate information, blood oxygen information, respiration information, or body temperature information. For example, the obtaining module 310 may obtain blood pressure information of the user from a blood pressure measurement device. For another example, the obtaining module 310 may obtain the body temperature information of the user from the body temperature probe.
In some embodiments, the user device 130 may display the acquired physiological information of the user. In some embodiments, the acquired physiological information of the user may be wirelessly or wiredly transmitted to an associated third party, such as a user's relative, a care provider, a hospital or care facility, etc., and displayed on a display device of the third party. In some embodiments, the acquired physiological information of the user may be stored partially or wholly in a local or remote storage device. For example, the user physiological information may be stored in one or more components of the intelligent wheelchair system 100 (e.g., the database 140 or the memory 230) or may be stored in a memory of a third party, such as a database of a hospital or care facility.
At step 420, the processor 220 (e.g., the analysis module 320) may analyze whether the physiological information of the user is within a preset safety threshold. In some embodiments, the preset safety threshold range may be preset by a user. In some embodiments, the preset safety threshold range may be determined by the intelligent wheelchair system 100 based on the physiological condition of the user. For example, the safety threshold ranges may be different for users of different genders, different ages, or different physical conditions. In some embodiments, the preset safe threshold range may be determined by the intelligent wheelchair system 100 according to the normal physical health parameters of the human in the database. For example, for the heartbeat information, the heartbeat of a normal adult is between 60 and 100 times/minute, and if the heartbeat of the user is lower than 60 times/minute or higher than 100 times/minute, it indicates that the user may be in a dangerous condition. In some embodiments, the preset safety threshold ranges may be stored in one or more components of the intelligent wheelchair system 100 (e.g., the database 140 or the memory 230).
If the physiological information of the user is within the preset safety threshold, the processor 220 (e.g., the obtaining module 310) may continue to obtain other physiological information of the user or the process is ended. If the physiological information of the user is not within the preset safety threshold range, go to step 430. At step 430, the processor 220 (e.g., the determination module 330) may determine alarm information. The alarm information may be text, voice, image or video, etc. The alarm information may include physiological information of the user, a preset safety threshold range of the physiological information, possible disorders, and the like.
At step 440, the processor 220 (e.g., the control module 340) may send the alert information to the user or an associated third party. For example, the control module 340 may send alert information to a user, a user's relative, a care giver, a medical service center, or the like. For example, the control module 340 may control the communication device 240 in the intelligent wheelchair system 100 to make an emergency call to a preset person, and may briefly notify the physical status of the user.
At step 450, the processor 220 (e.g., the control module 340) may control the smart wheelchair 110 to react to the emergency. The emergency response may include a flat, electric shock, moving the user away from a hazardous area, or assisting the user in taking medication, etc. In some embodiments, the control module 340 may determine the emergency response from the user's case. In some embodiments, the control module 340 may determine the emergency response based on the user's instructions. For example, if the user has severe arrhythmia, the control module 340 may control the smart wheelchair 110 to perform a shock operation on the user, so that the heartbeat of the user is recovered to be normal. For another example, if a cerebral hemorrhage such as sudden rise in blood pressure occurs in the user, the control module 340 may control the backrest 112 of the smart wheelchair 110 to tilt backward and maintain the seat 111 horizontal, so that the user lies flat on the smart wheelchair 110. In some embodiments, the control module 340 requires the user to determine the emergency response before controlling the smart wheelchair 110 to make the emergency response.
