Abstract

The invention provides a cloth detection system and a sewing machine. The cloth detection system comprises an infrared light emitting circuit and an infrared light detection circuit. The infrared light detection circuit comprises an infrared receiving circuit, wherein one end of the infrared receiving circuit is grounded and the other end is connected with a power source, and the infrared receiving circuit comprises an infrared receiving tube; the infrared light detection circuit also comprises an adjusting part which is used for adjusting the voltage difference between an emitter and a collector of the infrared receiving tube; the adjusting part comprises at least one adjusting circuit, wherein one end of the adjusting circuit is connected with the power source and the other end is connected with one end of the infrared receiving tube of the infrared receiving circuit, and the adjusting circuit is used for adjusting currents flowing through the adjusting circuit and further adjusting the voltage difference of the two ends of the infrared receiving tube. According to the technical solution, cloth of a sewing machine can be effectively detected by adjusting the VCE on the infrared receiving tube.

Description

technical field [0001] The invention relates to an electronic technology, in particular to a cloth detection system and a sewing machine. Background technique [0002] With the continuous development of industry, the intelligence of sewing machines is getting higher and higher. To achieve intelligence, the first thing to bear the brunt is to use sensors. The sensors on the machine are like human eyes. Without good eyes, human activities will be restricted. The fabric detection system of the sewing machine is the eyes of the intelligent sewing machine. Without the fabric detection system, the fabric cannot be identified, and the sewing machine cannot perform corresponding actions. The current fabric detection method generally emits infrared light through the infrared emitting tube. When the infrared receiving tube receives a relatively strong infrared signal, it is considered that there is no fabric on the sewing table. When the received infrared signal is weak or there is n...
