Wireless dual-core dual-wheel driven high-speed robot electric ward bed controller

Abstract

The invention discloses a wireless dual-core dual-wheel drive high-speed robot electric hospital bed controller, which includes an AC power supply, a battery, a control board, a wireless control device, a first motor, a second motor and a robot electric hospital bed. The control board adopts a dual-core The controller includes ARM and FPGA, and the ARM and FPGA communicate, and the ARM communicates with the external nursing station through a wireless control device. The forward, running speed and running direction of the robotic electric hospital bed are controlled by the first motor and the second motor. Through the above method, the present invention can reduce the workload and labor intensity of nurses or nurses through electric power assist, and transmit the electric bed body and patient information to the nursing center at any time through the wireless local area network, which can meet the needs of patients for the bed under different conditions.

Description

technical field [0001] The invention relates to an automatic control system for an electric hospital bed driven by a high-speed robot based on a wireless local area network dual-core and dual-wheel drive, belonging to the field of automatic electric hospital beds. 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 a...

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 in large numbers, and nurses are generally thinner. Moving patients through mechanical universal wheels makes nurses very strenuous 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, and 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 directions, 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 to pass 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 sen
