The invention discloses a door switch detection system based on a digital gyroscope, comprising: a gyroscope sensor, which is arranged in a door body of a peripheral device, and outputs a real-time angle value according to the movement of the door body; a distance sensor, which detects the distance between the door body and the peripheral device The first distance value between door frames; the controller stores: closing angle interval, distance and door state comparison table, angle and distance correspondence table; when the real-time angle value is in the closing angle interval, the signal of door closing is output; when When the real-time angle value is not in the closed angle interval, the first distance value is obtained, and the corresponding reference angle value is found according to the angle and distance correspondence table. When the error between the real-time angle value and the reference angle value is greater than the preset error, then The switch state of the door is obtained from the distance and door state comparison table according to the first distance value. This technology uses the distance sensor to detect whether the gyro sensor is within the normal detection error, and improves the accuracy of the system in judging the switch state of the door.
Description
technical field [0001] The invention relates to the technical field of door lock detection, in particular to a door switch detection system based on a digital gyroscope. Background technique [0002] With the development of technology and the improvement of people's requirements for safety, a detection system that can detect the switch state of the door appears, and the door is detected to be in the open state or closed state, and people can know the switch state of the door through the detection system. [0003] There is an existing door switch detection system that uses a gyro sensor as a detection element. The gyro sensor is installed on the door body. The gyro sensor generates a position value along with the movement of the door body, so that the current door position can be known, so that the door switch state can be known. . However, the gyro sensor is prone to inaccurate detection such as large position error or signal drift after the door is opened and closed many t...
