The controller 15 can be a PLC, a single chip microcomputer, or the like. The geriatric chair is more convenient control, is equipped with liquid crystal touch input screen, and the input screen is connected with controller 15, and input screen input signal is through 15 output signal of controller, and then controls the geriatric chair wholly, but each part angle of angle modulation geriatric chair wantonly. The input screen can be replaced by a control terminal such as a digital key and a mode button.
The top of the chair back 5 is provided with a visual detector. The vision detector is connected to the controller 15.
the working principle is that when the chair is not used by people, α is 170 degrees, β is 0 degree, gamma is 0 degree, and the chair is in an initial state.
when the old people sit on the chair statically, the old people chair is converted into the sitting state from the initial state, at the moment, the controller 15 acts to output a control signal, the angle sensor II, the motor II 11, the angle sensor IV and the motor IV 13 act, the motor II 11 and the motor IV 13 receive the control signal, the motor acts at the speed of 3 degrees/s to reach the sitting state, namely, α is about 170 degrees, β is 0 degrees, and gamma is about 5 degrees, the angle sensor IV and the angle sensor II detect the rotating angles of the chair back 5 and the foot rest cushion 2 and transmit the rotating angles to the controller 15, the controller 15 detects, if the control signal and the angle difference are within 1 degree, the operation is finished, if the angle difference is larger than 1 degree, the controller 15 outputs the control signal to the corresponding motor again until the difference meets the requirement.
when the old people feel the intention of lying down by sitting still, when a sign representing the lying down is selected through an input screen, such as infinity and the like, the controller 15 receives infinity signals, the vision detector identifies whether the sitting posture range of the old people is normal or not, the vision detector operates when detecting the normal posture range, the buzzer 16 alarms when detecting the abnormal posture range to remind the old people of adjusting safe sitting posture to lie down, or remind family people of helping the old people to help the old people, after the vision detector detects the normal posture, the second numerical value of the pressure sensor is recorded, the second numerical value of the pressure sensor is transmitted to the controller 15 in real time, when the second numerical value of the pressure sensor is larger than about 20N, the controller 15 outputs control signals which are respectively transmitted to the first motor 10 and the second motor 11, the third motor 12 and the fourth motor 13 receive control signals, the motors operate at the speed of 3 degrees/s to reach the lying down state, namely, α is about 95 degrees, α is about 0 degrees, α is about 90 degrees, the first angle sensor and the fourth angle sensor detects the rotating angles of the back 5 and the pedal 1, the controller 15, and the controller 15 ends up to outputting the control signals until the angle difference value of the control signals is larger than the angle difference value of the control signals, and the difference value of the control signals.
Further, the input screen may turn off pressure sensor two, at which time the controller 15 receives the "∞" signal, and the controller 15 outputs control signals to motor one 10 and motor four 13, with the remainder of the process as described above.
when the old people have the intention of getting up from lying down, the controller 15 receives a signal, the vision detector identifies whether the lying range of the old people is in accordance with the normal state, the operation is carried out when the detection is normal, the buzzer 16 alarms when the detection is abnormal, the old people are reminded to adjust the safe lying down to get ready for getting up, or family people are reminded to help the old people, after the vision detector detects the normal state, the controller 15 outputs control signals to be respectively sent to the motor II 11 and the motor IV 13, the motor II 11 and the motor IV 13 receive the control signals, the motor operates at the speed of 2 DEG/s to reach the lying down state, namely α is about 95 DEG, β is 0 DEG, gamma is about 90 DEG, the angle sensor IV and the angle sensor I detect the rotating angles of the chair back 5 and the pedal plate 1 and transmit the rotating angles to the controller 15, the controller 15 detects, if the control signals and the angle difference are within 3 DEG, the control is finished, if the control signals and the angle difference are respectively greater than 3 DEG, the controller 15 outputs control signals to the corresponding motor with the angle difference respectively greater than the angle difference of 3 DEG, until the difference is in accordance with the difference, namely the chair returns to the standing state.
When the old man stands up from sitting still, when the symbol representing standing up is selected through the input screen, the controller 15 receives a signal, the vision detector identifies whether the sitting posture range of the old man is in accordance with normal conditions, the old man acts when the detection is normal, the buzzer 16 gives an alarm when the detection is abnormal, and the old man is reminded to adjust the safe sitting posture to get up or remind family members to help the old man. After the vision detector detects normally, a value of the angle sensor is recorded, the value of the angle sensor is transmitted to the controller 15 in real time, when the difference between the value of the angle sensor and 125 degrees exceeds 3 degrees, the controller 15 outputs a control signal and transmits the control signal to the motor I10, the motor acts at the speed of 3 degrees/s, the value of the angle sensor is transmitted to the controller 15 in real time, when the difference between the value of the angle sensor and 125 degrees does not exceed 3 degrees, the controller 15 outputs the control signal and transmits the control signal to the motor I10, the action of the motor I10 stops, and the old can place feet on the ground conveniently.
further, when the difference between the real-time value of the angle sensor I and the real-time value of the angle sensor I does not exceed 3 degrees, the controller 15 outputs a control signal to the motor III 12, the motor operates at the speed of 3 degrees/s to reach a standing state, namely, α is about 95 degrees, β is about 35 degrees, and gamma is about 90 degrees, the angle sensor III detects the rotating angle of the cushion 3 and transmits the rotating angle to the controller 15, if the difference between the control signal and the angle is within 3 degrees, the operation is finished, and if the difference between the control signal and the angle is greater than 3 degrees, the controller 15 outputs the value of the control signal and the difference between the angle and the control signal is greater than 3 degrees again to the corresponding motor until the difference meets the requirement.
further, after the old people get up and the motor stops, when the vision detector detects that no people is on the old people chair, the vision detector outputs a homing signal, the controller 15 receives the homing signal, the controller 15 outputs a signal to the motor I10 and the motor III 12, the motor operates at a speed of 3 DEG/s to reach an initial state, namely α is about 170 DEG, β is about 0 DEG, and gamma is about 0 DEG, the angle sensor I and the angle sensor II detect the rotating angles of the pedal plate 1 and the foot rest pad 2 and transmit the rotating angles to the controller 15, and a control end detects the rotation angle, if the control signal and the angle difference are within 1 DEG, the rotation angle is finished, if the control signal and the angle difference are respectively greater than 1 DEG, the controller 15 outputs a control signal again, and respectively corresponding motors with the angle and the difference greater than 1 DEG until the difference meets the requirement.
The state of any angle adjustment: the chair for the old people can be fixed and static at any angle or specified angle through the input screen during adjustment of any angle.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
