Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic control, in particular to a portable height-adjustable operating stool. BACKGROUND

[0002] The operating stool is one of the common equipment in the hospital, and is widely used in operating rooms, emergency departments, ICUs and other medical places. The operating stool is usually square and is divided into high and low two kinds. The high stool is 80 cm high, and the low stool is 28 cm high. Medical staff can choose high or low stool according to height and use scene. For example, low stool is used for arterial puncture, which can provide medical staff to stand on it to operate, and high stool is used for rest during work interval.

[0003] However, the current operating stool is fixed in height and only has two choices, which is difficult to adapt to all application scenes. Therefore, a portable height-adjustable operating stool capable of automatically adjusting height to adapt to different use scenes is needed. SUMMARY

[0004] The present application provides a portable height-adjustable operating stool, which can automatically adjust height to adapt to different use scenes.

[0005] In order to solve the above technical problems, the present application provides the following technical scheme:

[0006] A portable height-adjustable operating stool, comprising a seat plate, an electric telescopic piece and a foot piece; the upper end of the electric telescopic piece is fixedly connected with the bottom surface of the seat plate, and the lower end of the electric telescopic piece is connected with the foot piece; further comprising a control module;

[0007] The control module comprises a driving unit, a collection unit and a processing unit; the collection unit is used for collecting environmental information; the processing unit is used for determining the current use scene according to the environmental information, determining the scene height according to the use scene and generating a height adjustment instruction, and sending the height adjustment instruction to the driving unit; the driving unit is used for controlling the electric telescopic piece to adjust to the scene height according to the height adjustment instruction.

[0008] The basic scheme principle and beneficial effects are as follows:

[0009] In the present application, the telescopic electric telescopic piece can be controlled to adjust the height of the operating stool to adapt to different use scenes. In the present application, the collection unit automatically collects environmental information, determines the current use scene according to the environmental information, and automatically adjusts the height, which can simplify the operation of the user. For example, in the operating room and emergency department, different scene heights can be set, and the operating stool automatically adjusts the height according to the location.

[0010] Further, the collection unit comprises a microphone, which is used to collect environmental sound information; the processing unit is further used to match the collected environmental sound with the pre-stored scene environmental sound to determine the current use scene.

[0011] For example, the operating room is quieter, while the emergency department has a large flow of people and a large noise. By collecting environmental sound information and matching it with pre-stored scene environmental sound, the current use scene can be effectively distinguished.

[0012] Further, the collection unit further comprises an inertial sensor, which is used to collect motion state information of the operating stool; the processing unit is further used to determine whether the operating stool is in a moving state according to the motion state information, and if so, determine whether the duration of the moving state exceeds a time threshold; if so, the processing unit is further used to match the collected environmental sound with the pre-stored scene environmental sound to determine the current use scene.

[0013] When the operating stool is moved for a long time, it is more likely to move from one space to another, and the use scene needs to be detected again. In the preferred embodiment, the moving state is detected by the inertial sensor, and when the duration of the moving state exceeds the time threshold, the collected environmental sound is matched with the pre-stored scene environmental sound, which can timely determine the current use scene, save computing power, and reduce power consumption compared with real-time matching.

[0014] Further, the control module further comprises a human body detection unit, which comprises a pressure sensor and at least four distance sensors; the pressure sensor is fixed in the seat plate, and the distance sensors are fixed on the circumferential surface of the electric telescopic member;

[0015] The processing module is used to acquire pressure information collected by the pressure sensor, and determine whether the current use state changes from a use state to a stop use state according to the pressure information; if so, after the user stops using, the processing module is further used to determine whether there is a pre-set state conversion word according to the environmental sound, and if so, acquire distance information collected by the distance sensors, and determine whether there is a moving target according to the distance information, and if so, continuously collect distance information of the moving target; the processing module is further used to determine whether the distance is greater than a first distance threshold according to the distance information of the moving target, and if so, the processing module is further used to determine whether there is another target within a second distance threshold according to the distance information, and if not, determine a state height according to the use state and generate a height adjustment instruction.

[0016] In the preferred solution, after the user uses it, the state conversion word said by the user is collected, for example, the state conversion word is rest, the word "rest" in "I need to rest" is detected, when the distance of the moving target is greater than the first distance threshold and there is no other target within the second distance threshold, the height corresponding to the use state is adjusted. Before adjusting the height, the analysis of the distance of the moving target confirms that the user has left the operating stool by a certain distance and there is no other user nearby, which can avoid the interference of adjusting the height on the user.

[0017] Further, the processing unit is further configured to identify whether there is a wake-up word according to the environmental sound, identify whether there is a height control voice if there is a wake-up word, determine a manual height adjustment based on the height control voice if there is a height control voice, generate a height adjustment instruction based on the manual height adjustment, and send the height adjustment instruction to the driving unit.

[0018] The user can conveniently adjust the height of the operating stool through voice.

[0019] Further, the control module further comprises a manual control unit, and the manual control unit is configured to receive a height adjustment signal. The processing unit is further configured to generate a height adjustment instruction based on the height adjustment signal and send the height adjustment instruction to the driving unit.

[0020] The user can manually adjust the height conveniently.

[0021] Further, the collection unit further comprises a Bluetooth module, configured to receive state height setting information and scene height setting information, and set default state height and default scene height based on the state height setting information and the scene height setting information respectively.

[0022] Further, the control module further comprises a display unit, configured to display the current height of the operating stool.

[0023] Further, the control module further comprises a power module, and the control module further comprises a power detection unit, configured to detect the remaining power of the power module. The processing unit is further configured to determine whether the remaining power is lower than a set value, and generate a reminder information if the remaining power is lower than the set value.

[0025] The following will be further described in detail through specific embodiments:

[0026] Embodiment one

[0028] The power module is used for supplying power to the control module. In the embodiment, the power module adopts a lithium battery.

[0029] The control module comprises a driving unit, a collecting unit, a processing unit, a human body detection unit, a manual control unit, a display unit and a power detection unit.

[0030] The collecting unit is used for collecting environmental information; the processing unit is used for determining the current use scene according to the environmental information, determining the scene height according to the use scene and generating a height adjustment instruction, and sending the height adjustment instruction to the driving unit; the driving unit is used for driving the driving motor to rotate according to the height adjustment instruction, adjusting the height of the lifting column, so as to achieve the purpose of controlling the electric telescopic part to adjust to the scene height.

[0031] Specifically, the collecting unit comprises a microphone, an inertial sensor and a Bluetooth module. The Bluetooth module is used for receiving state height setting information and scene height setting information, and setting default state heights and default scene heights according to the state height setting information and the scene height setting information respectively. For example, setting the default scene heights in the operating room scene and the emergency scene respectively, and setting the default state heights in the operating room scene under the working state and the resting state respectively.

[0032] The microphone is used for collecting environmental sound information; the inertial sensor is used for collecting motion state information of the operating stool, and the processing unit is further used for judging whether the operating stool is in a moving state according to the motion state information, if the operating stool is in the moving state, judging whether the duration of the moving state exceeds a time threshold, if the duration exceeds the time threshold, the processing unit is further used for matching the collected environmental sound with a pre-stored scene environmental sound to determine the current use scene. The time threshold is 30-60 seconds, and 60 seconds is adopted in the embodiment.

[0033] In the embodiment, the inertial sensor comprises an accelerometer and a gyroscope. When the operating stool starts to move, the accelerometer will detect the change of acceleration, and the gyroscope will detect the change of the angle of the operating stool.

Using deep learning technology, such as a convolutional neural network (CNN), an environment sound scene model is trained, so that the environment sound scene model can learn the statistical rules and characteristics of the environment sound from the feature vector. In real-time applications, the environment sound signal collected by the microphone is converted into a feature vector, and the environment sound scene model is used for inference, so as to identify the use scene corresponding to the current environment sound by comparing the similarity between the environment sound collected by the microphone and the scene sound model.

In the embodiment, the ultrasonic sensor simultaneously acquires distance information, and when the distance of a target in the same direction changes, it is considered that there is a moving target. The second distance threshold is less than the first distance threshold, and in the embodiment, the first distance threshold is 100 cm, and the second distance threshold is 40 cm.

[0037] The processing unit is further configured to identify whether there is a wake-up word according to the environment sound, and if so, to identify whether there is a height control voice, and if so, to determine a manual height adjustment based on the height control voice, to generate a height adjustment instruction based on the manual height adjustment, and to send the height adjustment instruction to the driving unit.

In the embodiment, the manual control unit uses two independent control buttons, one button controls the rising, and one button controls the falling.

[0039] The power detection unit is used to detect the residual power of the power module, and the processing unit is further used to judge whether the residual power is lower than a set value, and generate a reminder information if the residual power is lower than the set value.
