Anti-pinch function control device for electric windowing device

Abstract

The invention discloses an anti-pinch function control device for an electric windowing device. The voltage end of a Hall element for a shaft coding detection circuit is connected with a power supply positive pole and simultaneously grounded by a capacitor, the middle terminal of the Hall element is grounded, the signal end of the Hall element is connected with the lower end of a pull-up resistor and simultaneously connected with a 21-pin of a 16f1936 single-chip microcomputer by a resistor, the output end of a safety edge detection sensor of a safety edge detection circuit is connected with the lower end of a second pull-up resistor and simultaneously connected with a 11-pin of the 16f1936 single-chip microcomputer by the resistor, and the negative terminal of the safety edge detection sensor is grounded and simultaneously connected with the output end of the safety edge detection sensor by the capacitor and the resistor. The anti-pinch function control device is used for a rack rail type electric windowing device and a chain type electric windowing device. An anti-pin multifunctional electric windowing system is formed by a sensor and a shaft coder speed-adjustment control system, so as to facilitate the comprehensive coverage of an anti pinch detection area, the soft-starting of the circuit and the deceleration operation. The anti-pinch function control device can protect in the comprehensive anti-pinch area and is humanized and safe.

Description

technical field [0001] The invention relates to a control circuit of an electric window opener. Background technique [0002] The existing electric window opener control circuit includes a motor drive circuit, which can only realize the function of opening and closing the window, without the anti-pinch function. During operation, the electric window opener is easy to pinch people and is unsafe to use. Contents of the invention [0003] In order to overcome the defect that the known electric window opener control circuit has no anti-pinch function, the electric window opener is easy to pinch people during operation and is unsafe to use, the present invention provides an electric window opener anti-pinch function control device, The anti-pinch function control device of the electric window opener has an anti-pinch function, which makes the operation of the electric window opener safe. [0004] The technical solution of the present invention is: the anti-pinch function contr...
