5. A method of monitoring a safety monitoring system for an angle-adjustable suspension cage according to any one of claims 1 to 4, comprising the steps of:
The angle sensor of the angle monitoring mechanism measures the angle between the suspension cage and the upright post in real time, and transmits the measured angle signal to the control mechanism, and when the control mechanism receives the angle signal measured by the angle sensor and judges that the angle exceeds a limit angle, the control mechanism controls the execution assembly to give an alarm and perform power-off treatment;
when a safe angle is kept between the suspension cage and the upright post, the touch plate and the limit switch of the inclination limit protection mechanism are separated; when the angle between the cage and the upright post is increased, the shell is stretched, the distance between the touch plate and the limit switch is reduced, and the touch plate is triggered by contact with the limit switch until the angle between the cage and the upright post is increased to the limit angle; when the control mechanism receives a signal that the limit switch is triggered, the control execution assembly gives an alarm and performs power-off processing.
