Detailed Description

The present application will now be described in detail with reference to specific embodiments thereof as illustrated in the accompanying drawings. These embodiments are not intended to limit the present application, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present application.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

As shown in fig. 1, the voice lifting control device for a medical care bed according to the present embodiment includes a handheld terminal 1 and a distributed voice pickup apparatus 2 connected to the handheld terminal through wireless communication to implement voice data transmission;

the distributed voice pickup devices 2 are uniformly placed along the edge of the medical care bed, the distributed voice pickup devices 2 send received voice to the handheld terminal 1, and the handheld terminal 1 performs lifting control on a lifting platform in the medical care bed based on the received voice.

In the implementation, the pronunciation lift control device that this application embodiment provided carries out the distributed installation with the pronunciation pickup apparatus that sets up usually in fixed equipment such as handheld terminal 1, can expand the application range of pronunciation greatly for existing pickup mode, especially to this service environment of medical care bed, can avoid single pickup apparatus to lead to the emergence of voice control failure because of the less problem of pickup radius, and the user of being convenient for all can normal use pronunciation control the raising and lowering functions of medical care bed in the different positions of medical care bed. Typically, the voice pickup device used in the present embodiment is a miniature microphone.

Optionally, the distributed voice pickup apparatus 2 is further connected to the handheld terminal 1 through wireless communication.

In implementation, the purpose of limiting the use of wireless communication connection between the distributed voice pickup apparatus 2 and the handheld terminal 1 is to prevent the entanglement of the use of wired connection between the two. Meanwhile, the use range of the single voice pickup device and the handheld terminal is limited within the range of the medical care bed, so that the wireless transmission power of the voice pickup device is very low, the power consumption of the voice pickup device is reduced while the body of a patient is not influenced, and the use duration is prolonged. The wireless communication connection comprises one or more of ZigBee, WIFI, Bluetooth, 3G, 4G and 5G. When the communication connection mode has two or more modes, the operator can select the communication connection mode independently, and the condition that the communication can be continued when one communication mode cannot be carried out can be prevented.

Optionally, the handheld terminal 2 includes:

a key interaction unit 21 for receiving a key signal obtained by a key action;

a micro control unit 22 for converting the received key signal into a lifting control signal and sending the lifting control signal to the execution lifting platform;

and a lifting execution unit 23 for executing the lifting operation of the lifting platform according to the lifting control signal.

In practice, in addition to the voice control of the medical care bed proposed in the foregoing, the medical care bed proposed in the embodiment of the present application can be operated according to a handheld terminal. As shown in fig. 2, the handheld terminal 2 includes a key interaction unit 21, a micro control unit 22, and a lifting execution unit 23. The key interaction unit is a single or a plurality of physical keys or capacitive touch keys arranged on the handheld terminal and is used for receiving a control instruction of a user, the elevation execution unit 23 is typically an electric push rod, and after the micro control unit 22 analyzes the control instruction, the elevation and other movements of the medical care bed can be realized through the cooperation of a built-in motor, a worm and other components.

The key signal may also include an up instruction, a down instruction, a reset instruction, and a back instruction, and the keys of the key interaction unit 4 may be set as follows: the device comprises a rising key for sending a rising instruction, a falling key for sending a falling instruction, a reset key for sending a reset instruction and a backspace key for sending a backspace instruction. At this moment, the voice broadcast device can also be used for playing the sound prompt corresponding to the lifting control signal. For example, when the command is raised, the voice announcer plays the sound "raise" and so on.

The distributed voice pickup apparatus 2 based on the foregoing collects the voice signal and transmits the voice signal to the micro control unit 22. The micro control unit 22 identifies and transcodes the voice signal, and mainly identifies whether the voice signal contains keywords with similar semantics such as 'rising, falling, stopping and resetting', and can also compare the keywords with a voice database stored in a memory. After the identification and transcoding, the micro control unit 22 converts the voice signal into a lifting control signal such as a lifting instruction, a descending instruction, a reset instruction, a backspacing instruction and the like, and the lifting execution unit 23 executes the lifting operation of the lifting platform.

Optionally, the 2 handheld terminal further includes a storage unit 24;

the storage unit 24 is electrically connected with the micro control unit 22 and is used for storing the voice signal and the lifting control signal obtained by converting the voice signal.

In implementation, in order to enable the record of the voice-controlled lifting condition to be inquired, the handheld terminal 2 further comprises a storage unit 24, and the storage unit 24 is electrically connected with the micro-control unit 22 and is used for storing the voice signal and the lifting control signal converted from the voice signal.

Optionally, a single voice pickup device 25 and a sound generating device 26 are further arranged in the handheld terminal 2, and a sound through hole shared by the single voice pickup device and the sound generating device is formed in the surface of the housing of the handheld terminal 2.

In implementation, in order to enhance the voice recognition effect, a single voice pickup device 25 different from the aforementioned distributed voice pickup device 2 is added to the handheld terminal. The use of the medical care bed can be controlled by using a voice control mode by enabling the handheld terminal 2 to be close to the mouth when the user holds the handheld terminal 2 on the medical care bed. Due to the limitation of the fixity of the distributed voice pickup device 2, the mobile voice pickup device installed on the handheld terminal 2 can improve the convenience of voice control. Furthermore, a sound generating device 26 for playing a sound prompt corresponding to the lifting control signal is further disposed on the handheld terminal 2. The sound generator 26 may further include a voice announcer for playing a sound alert corresponding to the lift control signal. For example, when the command is raised, the voice announcer plays the sound "raise" and so on.

In consideration of the waterproof requirement in the use environment of the user, as shown in fig. 3, the present embodiment defines that the single voice pickup device 25 and the sound generating device 26 on the handheld terminal 2 share a set of sound through holes. Compared with the design of independently using the sound through holes in the prior art, the mode of limiting one sound through hole to be shared can reduce the open hole on the handheld terminal 2, and the difficulty of waterproof design of the handheld terminal 2 is reduced.
