Multi- mode care bed BCI system based on cloud platform

Abstract

The invention discloses a multi-mode care bed BCI system based on a cloud platform. The multi-mode care bed BCI system comprises a picture display unit, a data acquisition and transmission unit, a data receiving and processing unit, and a care bed status and environment information acquisition and transmission unit. The multi-mode care bed BCI system has the following advantages: (1) it uses two TGAM modules to collect brain wave signals, does not have excessive electrodes, and is convenient to use; (2) it has a variety of signal acquisition modes, integrates visual inspiration, movement imagination and voice recognition in one, achieves multi-mode control on a care bed, has a wide range of applications and good stability; (3) as brainwave signals are processed by an ARM processor and theARM processor uses a large number of registers, the brainwave signal processing classification is speeded up and at the same time size of the care bed BCI system is greatly reduced; (4) as the cloud platform is used to store data, the status information of the care bed and the environmental information around the care bed can be uploaded to the cloud platform in real time, which makes it convenient for users to view the information and enables family members to monitor the patient in real time.

Description

technical field [0001] The invention relates to a nursing bed BCI system, in particular to a multi-mode nursing bed BCI system based on a cloud platform, which belongs to the technical field of control systems. Background technique [0002] The traditional automatic nursing bed can realize the conversion of postures such as lifting the back to sit up, bending the legs, stretching the legs, and turning left and right. Most of these automatic nursing beds use the manual mode, that is, the linear push rod is used as the power source, and the conversion of postures such as lifting the back to sit up, bending the legs, extending the legs, turning left and right, etc. is realized through the mechanical structure of the connecting rod hinge, so as to prevent the patient from lying in bed for a long time. Complications such as bedsores. However, the manual mode operation of the automatic nursing bed is cumbersome, and the mechanical part will produce noise after a long time of use....

AI Technical Summary

Problems solved by technology

[0010] 1. Using a medical brainwave tester to collect brainwaves, there are too many electrodes, which is inconvenient for patients to use;

[0011] 2. The brain wave acquisition mode of the medical brain wave tester is single and not widely applicable;

[0012] 3. The brain wave signal of the medical brain wave tester is sent to the computer through the serial cable connection, which is bulky and difficult to wear and move;

[0013] 4. Nursing bed information and environmental information can only be displayed on the human-computer interface of the bed body, and family members cannot monitor it in real time
