Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve controller technology, and in particular to a wireless electromagnetic valve controller. Background Technology

[0002] Solenoid valve controllers play a crucial role in industrial automation, fluid control, and smart homes, controlling the on / off state of solenoid valves to regulate fluid flow. Traditional solenoid valve controllers mostly use wired connections, linking the controller to the solenoid valve via wires. However, this wired connection method has the following problems:

[0003] Complex cabling: In complex applications, such as large industrial equipment or remote control applications, wired connections require laying a large number of cables, resulting in high installation costs and a cumbersome process. Furthermore, cables are susceptible to interference from environmental factors (such as corrosion and mechanical damage), leading to unstable signal transmission.

[0004] Poor flexibility: Once installed, the controller's location is fixed and difficult to adjust according to actual needs. The limitations of wired controllers are particularly pronounced in scenarios requiring mobile equipment or frequent changes to control points.

[0005] Limited signal transmission distance: The signal transmission distance of wired connections is limited by the length of the cable, making it difficult to achieve long-distance control.

[0006] High maintenance costs: Cables are prone to failure due to aging, damage or external interference, which increases the maintenance cost and difficulty of the system.

[0007] With the development of wireless communication technology, wireless solenoid valve controllers have gradually become a solution to replace traditional wired controllers. However, existing wireless solenoid valve controllers still have some shortcomings in design and functionality:

[0008] Insufficient signal stability: Some wireless controllers are susceptible to interference in complex environments, leading to unstable signal transmission and affecting the reliability of control.

[0009] High power consumption: Although wireless communication avoids wiring problems, some wireless controllers still consume a lot of power, especially in scenarios with long-term operation or frequent communication, where battery life is limited.

[0010] Limited functionality: Most existing wireless solenoid valve controllers only have basic on / off control functions and lack intelligent functions such as status indication, alarm prompts, and program upgrades, resulting in a poor user experience.

[0011] Complex structure: Some wireless controllers have complex internal structures, making assembly and maintenance inconvenient, which increases production costs and maintenance difficulty. Utility Model Content
