Description

technical field [0001] The invention relates to an automatic control system for an electric sickbed of a dual-core single-wheel drive medical robot, belonging to the technical field of automatic electric sickbeds. Background technique [0002] The medical bed system is a device used to carry patients in the hospital ward. At present, the medical beds used in hospitals in developed countries are basically all automated, and multifunctional electric beds have also been used in family beds and community hospital beds. Some medical beds can be changed in shape by external force to assist in adjusting the patient's position, and some of the accessories have the effect of promoting the recovery of patients; controllable electric beds are relatively advanced automation products, which have the advantages of saving time and effort. Due to the characteristics of electric control, the control keys can be installed in any range that allows the hospital bed to receive signals, which im...

AI Technical Summary

Problems solved by technology

[0005] (1) Part of the existing hospital beds are supported by four fixed feet in contact with the ground, and the patients are fixed in a certain closed environment. With the long-term hospitalization of the patients, it has caused great physical and mental damage to the patients. s damage

[0006] (2) Although some beds have changed the fixed feet to mechanical universal wheels, the beds can be moved to a certain space by the medical staff, but due to the random movement of the beds, sometimes there will be misoperation, and sometimes it will hurt the patient. patient

[0007] (3) With the improvement of the quality of life of modern human beings, the number of obese patients has increased a lot, and the nurses are generally thinner. Moving patients through mechanical universal wheels makes the nurses very laborious and increases the labor intensity.

[0008] (4) With the aggravation of aging, a large number of elderly people also increase the demand for hospital beds, and there are relatively few nursing staff now. The hospital beds based on mechanical universal wheels increase the labor intensity of nursing staff

[0009] (5) All mechanical beds are generally fixed in a certain position, and once they need to be moved or changed direction, they need to be completed by external personnel, which increases the workload of nurses

[0010] (6) Even if the current mechanical hospital bed can be pushed to the external environment through the door of the ward by external force, due to the relatively low degree of automation of human operation, it takes some time to adjust the posture of the bed before passing through the door of the ward

[0011] (7) Even if the current mechanical hospital bed can reach the environment outside the ward through the support of mechanical universal wheels, it not only adjusts the patient's body and mind, but also increases the workload of the nurses, especially when passing through the climbing place. The physical strength of the nursing staff puts forward higher requirements

[0012] (8) Although the single-wheel-driven electric hospital bed can well satisfy the decoupling of the speed and direction of the hospital bed, the power of the single-wheel-driven walking motor is relatively large, which sometimes causes the phenomenon of large horses and small carts

[0013] (9) Since there is only one contact point between the power of the single-wheel drive electric hospital bed and the ground, it is difficult to precisely control the direction of its movement, and a slight disturbance can cause a large direction change

[0014] (10) The robot electric hospital bed based on single-core control must not only handle the servo control of multi-axis motors, but also process the sampling data of various sensors of the robot hospital bed. Since the single-core processor processes more data, the calculation speed is not very fast. , which is not conducive to the high-speed operation of the robot, and sometimes the robot bed is out of control due to the large amount of processing data

[0015] (11) Due to the frequent braking and starting of the robot electric hospital bed during operation, the workload of the single-core controller is increased, and the single-core controller cannot meet the requirements for rapid start and stop of the robot electric hospital bed

[0016] (12) Due to the interference of unstable factors in the surrounding environment, the controller of the single-core robot electric hospital bed often appears abnormal, causing the robot bed to lose control during driving, and the anti-interference ability is poor

[0017] (13) For some simple beds, once the electric power assist part is added, it is easy to leave the ward. Once the electric bed leaves the ward, even if there is a problem with the electric bed body and the patient is in danger, the medical staff can no longer obtain any information about it.

[0018] (14) Due to the aggravation of aging, there is a shortage of nurses. For some patients who take care of themselves for a short time, even if there is a danger in the ward, they cannot communicate with the medical staff and nurses in time, and sometimes cause certain injuries.

[0019] (15) In order to protect the electric hospital bed from being misoperated, the robot hospital bed has opened various protection permissions, which requires the medical staff to activate these permissions on site, which increases the workload of the medical staff and is very time-consuming

[0020] (16) Most of the parameter monitoring of the simple electric hospital bed is still in the control mode of on-site monitoring and on-site storage during the movement of the simple electric hospital bed. Once the electric hospital bed fails, production personnel need to go to the scene to check and control it, which is not conducive to the development of highly automated robot electric hospital beds.
