[0002] With the deepening of Industry 4.0, the manufacturing industry has placed higher demands on the intelligence, informatization, and efficiency of automated equipment, prompting continuous technological innovation in related fields. However, in existing pneumatic shut-off valve control devices, traditional feedback devices, due to their limited feedback information, typically only provide simple on / off status, making it difficult to meet the needs of intelligent manufacturing. These feedback devices often require multiple signal lines to transmit basic information, increasing wiring complexity and resulting in a cumbersome and inefficient design. Furthermore, the feedback device and solenoid valve are mostly designed separately, requiring multiple lines to connect and transmit control and feedback signals. This traditional structure not only increases the difficulty and cost of on-site wiring but also limits the system's information transmission capabilities to some extent, failing to effectively provide detailed status information of the equipment.
