Description

Technical Field

[0001] The utility model relates to the technical field of smart agricultural irrigation, in particular to an intelligent irrigation terminal controller. Background Art

[0002] The card swipe irrigation controller is an important component of an intelligent irrigation management system. It controls and manages irrigation equipment by swiping cards. This controller combines radio frequency identification (RFID) or IC card technology. Users can use specific cards to swipe the controller to start or stop irrigation equipment. The working principle of the card swipe control irrigation controller is relatively simple. When users need irrigation, they will swipe the IC card or RFID card with corresponding permissions close to the sensing area of ​​the controller. The controller reads the information in the card and verifies the user's identity and permissions. If the verification is successful, the controller will send a signal to the irrigation equipment, such as a solenoid valve or water pump, to start or stop the water flow.

[0003] When designing existing irrigation terminal controllers, it is necessary to connect to a variety of external electrical equipment and sensor devices to ensure the normal operation of the system and accurate data collection. These devices are usually connected to the controller through power cables, and the access points of the cables are equipped with protective mechanisms to prevent the external environment from causing adverse effects on the circuit. However, these protective mechanisms often use rotating covers or sliding detachable structures. Although they facilitate the connection and disconnection of circuits, their protective effects are inadequate when faced with the complex and changeable working environment of irrigation terminals. The working environment of irrigation terminal controllers is full of uncertainty. They may be installed outdoors, exposed to wind, frost, rain and snow, or they may be placed inside a control box and closely connected to vibration sources such as water pumps. These external factors, such as vibrations generated by the operation of water pumps and humid outdoor air, may have adverse effects on the wiring status of the circuit. Vibration may cause the wiring to loosen, thereby affecting the stability of the circuit; while a humid environment may corrode the wiring ports and increase the risk of short circuits. Utility Model Content
