Description

Technical Field

[0001] This utility model belongs to the field of intelligent water and electricity pile technology, and in particular relates to a main control integrated circuit for intelligent water and electricity piles used in RV campsites. Background Technology

[0002] Existing smart hydroelectric piles have the following problems:

[0003] 1. High dependence on human intervention: Operation, billing, and troubleshooting all require human intervention;

[0004] 2. Low efficiency of manual management: Water and electricity consumption are measured by ordinary water meters and electricity meters, and the data needs to be manually recorded or prepaid through IC cards;

[0005] 3. Poor user experience: Cumbersome operation (plugging and unplugging cables, manual switching), limited payment methods (only supporting physical IC cards or cash top-ups, failing to meet mobile payment needs); opaque information, unable to view usage and costs in real time, making users prone to questioning the accuracy of billing.

[0006] 4. No remote communication function; manual inspection of equipment status is required (e.g., checking water pressure and voltage).

[0007] 5. Insufficient electrical safety; relying solely on fuses or circuit breakers for overload protection, unable to monitor leakage current in real time.

[0008] 6. Limited functionality, only supporting water and electricity supply, unable to be expanded with additional functions such as charging piles and environmental monitoring;

[0009] 7. Waste of resources: The system remains in standby mode when no one is using it (such as water pump running idle or circuit standby), resulting in meaningless water and electricity consumption; there is no intelligent shutdown function, and users may forget to turn off the valve or power supply, resulting in "continuous water flow" and "no-load power consumption".
