Abstract
Description
Technical Field
[0001] This utility model relates to the field of digital television, and more particularly to a system for preventing falls from the bed. Background Technology
[0002] Traditional beds mainly consist of a headboard and a base. The base lacks any safety features to prevent people from falling while sleeping. This poses a significant risk, especially for young children or the elderly. Falling from a bed at a certain height can easily cause serious injury.
[0003] To prevent sleepers from falling out of bed, new types of beds with fall protection features have emerged in the market in recent years. For example, some beds have guardrails on both sides to prevent the sleeper from falling. However, this method restricts the use of the bed and limits the user's freedom of movement. Newer methods use pressure sensors or infrared sensors to detect the user's position and prevent falls. These methods are less suitable for modifying existing bedding, resulting in less flexibility in configuration. Utility Model Content
[0004] The purpose of this invention is to provide a flexibly configurable system for preventing falls from the bed.
[0005] In this embodiment of the invention, a system for preventing falls from a bed is provided, comprising: a monitoring module installed in the room, ultra-wideband tags installed at the four corners of the bed, and an ultra-wideband tag worn by the user. The monitoring module includes an ultra-wideband positioning unit and a control unit. The ultra-wideband positioning unit is used to locate the ultra-wideband tags at the four corners of the bed to determine the boundaries of the bed. The control unit sets a warning zone based on the boundaries of the bed. The ultra-wideband positioning unit further locates the ultra-wideband tag worn by the user. When the ultra-wideband tag worn by the user appears in the set warning zone, the control unit issues a fall prevention control command.
[0006] In this embodiment of the invention, the ultra-wideband positioning unit includes at least three ultra-wideband antennas arranged in a triangular pattern.
[0007] In this embodiment of the invention, the control module further includes a wireless communication unit.
[0008] In this embodiment of the invention, the wireless communication unit is a Bluetooth module, a WiFi module, or a 5G module.
[0009] In this embodiment of the invention, the system for preventing falls from the bed further includes electrically controlled liftable guardrails located on both sides of the bed and communicating wirelessly with the control module. The fall prevention control command is used to control the safety guardrails to rise.
[0010] In this embodiment of the invention, the system for preventing falls from the bed also includes an alarm device worn by the user that is wirelessly connected to the control module, and the fall prevention control command is used to control the alarm device to issue an alarm signal.
[0011] In this embodiment of the invention, the alarm device includes a buzzer and / or a vibration motor.
[0012] In this embodiment of the invention, the monitoring module is positioned directly above the bed or embedded within the bed.
[0013] Compared with existing technologies, the system for preventing falls from the bed in this invention uses an ultra-wideband positioning unit to locate ultra-wideband tags at the four corners of the bed to determine the bed's boundaries. The ultra-wideband positioning unit further locates the ultra-wideband tag worn by the user. When the ultra-wideband tag worn by the user appears in the set warning area, the control unit issues a fall prevention control command. The fall prevention control command controls the bed railing to rise to prevent the user from falling. The fall prevention control command can also issue an alarm signal to wake up the user and prevent them from falling. Furthermore, the system for preventing falls from the bed in this invention can be implemented without modifying existing bedding, making it flexible in application. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the structure of a system for preventing falls from the bed according to an embodiment of the present invention.
[0015] Figure 2 This is a schematic diagram showing the warning zone and safety zone of the bed in an embodiment of this utility model. Detailed Implementation
[0016] like Figure 1 As shown in the embodiment of this utility model, a system for preventing falls from the bed is provided, which includes: a monitoring module 1 installed in the room, ultra-wideband tags 2 installed at the four corners of the bed 5, ultra-wideband tags 3 worn by the user, and an alarm device 4 worn by the user.
[0017] The monitoring module 1 includes an ultra-wideband positioning unit 11, a control unit 12, and a wireless communication unit 13. The ultra-wideband positioning unit 11 is used to locate the ultra-wideband tags 1 at the four corners of the bed to determine the bed's boundaries. The control unit 12 sets warning zones and safety zones based on the bed's boundaries, such as... Figure 2 As shown. The ultra-wideband positioning unit 11 further locates the ultra-wideband tag 3 worn by the user. When the ultra-wideband tag 3 worn by the user appears in the set warning area, the control unit 1 issues a fall prevention control command.
[0018] It should be noted that, in this embodiment of the present invention, the ultra-wideband positioning unit 11 includes at least three ultra-wideband antennas arranged in a triangle. The control unit 12 defines the plane where the three ultra-wideband antennas are located as the xoy plane, and the z-axis and the xoy plane form a right-handed coordinate system, thereby establishing a three-dimensional coordinate system to locate the ultra-wideband tags 1 at the four corners of the bed and the ultra-wideband tags 3 worn by the user.
[0019] In this embodiment of the invention, the wireless communication unit 13 is a Bluetooth module, a WiFi module, or a 5G module. It is used to wirelessly connect with the alarm device 4 worn by the user and to send the fall prevention control command issued by the control unit 1 to the alarm device 4. The alarm device 4 includes a buzzer and / or a vibration motor. Upon receiving the fall prevention control command, it generates an alarm sound and / or vibration to wake the sleeping user and prevent them from falling off the bed. Furthermore, the wireless communication unit 13 also establishes a connection with the caregiver system. When there is a risk of the user falling, the control unit 1 notifies the caregiver through the wireless communication unit 13 to handle the situation.
[0020] The monitoring module 1 can be set directly above the bed or embedded in the bed. The ultra-wideband tag 2 is set at the four corners of the bed. The ultra-wideband tag 3 worn by the user and the alarm device 4 are also present. It can be seen that the system for preventing falls from the bed can be easily installed and used without modifying the bedding.
[0021] In the above embodiments, when there is a risk of the user falling off the bed, the user needs to be woken up to prevent the fall, which is detrimental to the user's sleep. Therefore, in another embodiment of this utility model, the system for preventing falls from the bed includes electrically controlled liftable guardrails installed on both sides of the bed and maintaining wireless communication with the control module 1. The fall prevention control command is used to control the safety guardrails to rise. By using electrically controlled liftable guardrails to protect the user in a sleeping state, the user does not need to wear the alarm device 4, and the user can get better sleep. Of course, for beds equipped with electrically controlled guardrails, the system for preventing falls from the bed only needs to include the monitoring module 1, the ultra-wideband tag 2, and the ultra-wideband tag 3.
[0022] In summary, the system for preventing falls from the bed according to this invention uses an ultra-wideband positioning unit to locate ultra-wideband tags at the four corners of the bed to determine the bed's boundaries. The ultra-wideband positioning unit further locates the ultra-wideband tag worn by the user. When the user's ultra-wideband tag appears in the designated warning area, the control unit issues a fall prevention control command. This command causes the bed railing to rise to prevent the user from falling. The fall prevention control command can also issue an alarm signal to wake the user and prevent further falls. Furthermore, this system for preventing falls from the bed can be implemented without modifying existing bedding, making it flexible in application.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
