Bus window system with anti-pinch function

Abstract

The invention discloses a bus window system with the anti-pinch function. The system comprises an MCU module, a motor driving circuit, a motor current detection circuit, a switch control circuit, a signal processing circuit, a motor unit, a glass moving mechanism, a bus window, a raindrop sensor and a photoelectric sensor; the motor unit is connected with a bus window through the glass moving mechanism; the photoelectric sensor and the raindrop sensor are connected with the MCU module; the MCU module, the signal processing circuit, the switch control circuit and the motor unit are connected insequence; the motor current detection circuit is connected with the MCU module; and the MCU module is connected with the motor unit through the motor driving circuit.

Description

technical field [0001] The invention belongs to the technical field of control, in particular to an anti-pinch window system for a bus. Background technique [0002] Existing buses generally use mechanical glass windows. The windows need to be manually operated, and the driver cannot remotely control them. Even if electric windows are installed in some vehicles, there is still a lack of a bus anti-trapping system. The car window system, when the car window rises and encounters obstacles such as hands and heads, it can automatically back to the end, so as to avoid accidents. Many car window anti-trapping uses the Hall sensor to judge the position of the glass. If there is a foreign object blocking the glass's rising during the glass rising process, the electric window will stop rising immediately and immediately drop to the bottom to realize the anti-trapping function. Contents of the invention [0003] The object of the present invention is to propose a bus anti-pinch win...
