Description

Technical Field

[0001] The utility model relates to the technical field of control equipment, in particular to an automatic control device for micro-sprinkler irrigation in saline-alkali land. Background Art

[0002] At present, for the convenience of use, the existing automatic control equipment for saline-alkali land micro-sprinkler irrigation equipment mainly includes sensors, controllers, relays (relays are used to control the start and stop and direction switching of the motor. By controlling the state of the relay, the water pump motor can be controlled), communication modules (including wireless communication modules, network communication modules) and protection elements (including overload protectors, short-circuit protectors, overvoltage protectors, etc.). The working status of the water pump motor is monitored in real time through sensors, including current, voltage, phase balance, power and other parameters. When the water pump motor is running, the sensor sends the monitored parameters to the controller, and the controller analyzes and judges the motor status. If an abnormality is found, such as overload or undervoltage, the controller will trigger the corresponding protection measures (cut off the current or take other protection measures). At the same time, the information is fed back to the remote control center through the communication module, and the remote control function is realized according to the control instructions, thereby realizing the protection and remote control of the water pump motor. Such automatic control devices can automatically control and protect according to preset parameters and logic, thereby improving the stability and reliability of the equipment.

[0003] When using existing automated control devices, the angle of the whip antenna (i.e., wireless communication module) on the controller with a display screen must be manually adjusted to change the relative position of the antenna and the signal source, helping to optimize the strength and quality of signal reception. However, these existing whip antennas are mostly used outdoors. In rainy, snowy, or windy weather, the whip antenna's angle can easily change due to force majeure, resulting in poor signal quality or signal interference. Furthermore, these automated control devices are often installed outdoors using screws. Long-term exposure to air can cause the screws to rust, making later disassembly difficult. Improvements are needed. Utility Model Content
