Abstract
The utility model discloses a wheelchair horizontality detects and control system, it includes: the inclination angle sensor is arranged on the wheelchair and used for collecting inclination angle signals of the wheelchair; the lifting motors are correspondingly arranged in the travelling wheels of the wheelchair and used for adjusting the height of the travelling wheels from the frame; the controller is used for generating a lifting motor control signal according to the received inclination angle signal transmitted by the inclination angle sensor and sending the lifting motor control signal to the lifting motor to drive the lifting motor to act.
Description
Technical field
This utility model relates to a kind of wheelchair level measurement and control system.
Background technology
At present, China is applied to the wheelchair of disability personnel and old people substantially based on manual wheelchair, and the intelligence degree of electric wheelchair is also lower, and the dependency of travelling people person to the personnel that protect that are situated between is larger.The raising required along with travelling people person and alleviation Jie protect the pressure of personnel, just progressively the carrying out and go deep into of wheelchair Study of intelligent, how to ensure wheelchair in traveling process because of wheelchair tilt problem that the factor such as slope, Uneven road causes, thus ensure to take advantage of a person to be in human body horizontal equilibrium state, be the problem wanting in a hurry to solve.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, a kind of wheelchair level measurement and control system is provided, it can keep wheelchair to be level automatically, effectively prevent the phenomenon that wheelchair that wheelchair causes because of the factor such as slope, Uneven road in traveling process tilts, alleviate the pressure of the personnel that protect that are situated between.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of wheelchair level measurement and control system, and it comprises:
Obliquity sensor, described obliquity sensor is arranged on wheelchair, and for gathering the inclination angle signal of wheelchair;
Multiple lifting motor, described each lifting motor is arranged in each road wheel of wheelchair accordingly, for regulating road wheel from the height of vehicle frame;
Controller, the signal input part of described controller is connected with the signal output part of obliquity sensor, the control output end of described controller is connected with the control input end of multiple lifting motor respectively, the inclination angle signal that described controller is used for transmitting according to the obliquity sensor received produces lifting motor control signal, and sends to lifting motor to drive its action this lifting motor control signal.
Further provide a kind of concrete structure of controller, controller has sampling filter circuit, governor circuit and motor-drive circuit, the signal input part of sampling filter circuit is connected with the signal output part of obliquity sensor, the signal output part of sampling filter circuit is connected with the signal input part of governor circuit, the signal output part of governor circuit is connected with the signal input part of motor-drive circuit, and the signal output part of motor-drive circuit is connected with the control input end of multiple lifting motor.
After have employed technique scheme, this utility model detects the level of sampling wheelchair by obliquity sensor, obtain respective horizontal state parameter, pass to controller, and through signal processing, then operated by motor-drive circuit drive motors, accurate level is remained on to realize wheelchair, this utility model can effectively prevent the inclination of wheelchair in traveling process from even to topple phenomenon, thus improves the intelligent level of wheelchair, alleviates Jie and protects personnel's pressure.
Accompanying drawing explanation
Fig. 1 is the theory diagram of wheelchair level measurement and control system of the present utility model.
Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, this utility model is described in further detail.
As shown in Figure 1, a kind of wheelchair level measurement and control system, it comprises:
