[0091] Below, in conjunction with Figure 3 The circuit connection of the open circuit sensor is explained.

[0092] Figure 3 This is a circuit connection diagram of a disconnection sensor provided in an embodiment of this application. Please refer to... Figure 3 , Figure 3 This includes infrared circuitry. Infrared circuitry consists of transmitting and receiving circuits.

[0093] The infrared pair 203 includes a transmitter and a receiver; the transmitting circuit is connected to the transmitter, and the receiving circuit is connected to the receiver.

[0094] The transmitting circuit may include an oscillating circuit.

[0095] The receiving circuit may include a receiving sub-circuit, a level comparison sub-circuit, and an output sub-circuit, which are connected in sequence.

[0096] The transmitting circuit is used to generate infrared signals.

[0097] The transmitter is used to emit infrared signals within the active range.

[0098] The receiver is used to receive the response signal corresponding to the infrared signal.

[0099] The receiving circuit is used to detect the yarn state by responding to the signal, generate a detection signal, and send the detection signal to the yarn breakage signal adapter board 102.

[0100] The line connecting the transmitter and receiver is orthogonal to the line connecting the first wire guide and the second wire guide.

[0101] The oscillation circuit can be used to generate a 36kHz pulse signal and transmit it through the transmitter.

[0102] Optionally, the receiver sub-circuit can be used to receive a response signal.

[0103] The level comparison sub-circuit can be used to determine the reference level value. Based on the level value corresponding to the response signal and the reference level value, the yarn state corresponding to the yarn is detected to generate a detection signal.

[0104] The output sub-circuit can be used to send a detection signal to the disconnection signal adapter board.

[0105] Optionally, the level comparison sub-circuit is used to generate multiple first signals within a preset time period based on the level value corresponding to the response signal and the reference level value, and to detect the yarn state corresponding to the yarn based on the multiple first signals.
