Control method of simple pendulum working device

Abstract

The invention discloses a control method of a simple pendulum working device. The method comprises the following steps of: selecting N sampling points within a swinging period T of the simple pendulum working device, and setting and storing the corresponding circuit parameter preset values of each sampling point; detecting positive and opposite output circuit parameters of a power device as practical detection values at any sampling point of the simple pendulum working device and sending the output circuit parameters to an MCU(Microprogrammed Control Unit); comparing the practical detection values with the stored preset values by the MCU by corresponding each sampling point; when the practical detection values are larger than the preset values, waiting for next sampling, and when the practical detection values are smaller than the preset values, calculating difference values between the practical detection values and the preset values; and multiplying the difference values with a lifting / descending correction coefficient according to a working state of a simple pendulum at the moment so as to improve the power of the power device. The control method can ensure that the swinging amplitude of the simple pendulum working device is maintained unchanged so as to improve the use effect and the comfort level.

Description

technical field [0001] The invention relates to a swing device, in particular to a control method capable of effectively stabilizing the swing amplitude of a single pendulum working device such as an electric swing or an electric rocking chair. Background technique [0002] Electric swings and electric rocking chairs are typical single pendulum working devices, which are mainly used in daily life. Taking electric rocking chairs as an example, ordinary electric rocking chairs mainly include a bracket and a swing body. The bracket is fixed on the ground, and the swing body can be Swingingly arranged on the support, the swinging body is provided with an accommodation room, and the baby can lie down or sit in it; after the power is turned on, the motor drives the rotating shaft to rotate, thereby driving the swinging body to swing back and forth, making it easy for the baby to fall asleep or get up For the purpose of entertainment, electric rocking chairs are more convenient and...

Problems solved by technology

However, due to the poor anti-interference performance of the optical sensor, it is easily disturbed by the external environment during the detection process, resulting in inaccurate detection results and little improvement in the use effect; and the optical sensor cannot achieve full detection within the swing angle range. That is, there is a large blind area, and the symmetry of the swing angle cannot be guaranteed, which greatly affects the comfort of the product.
