Can the electricity meter for apartment fee control achieve remote tripping and closing?

1、 Implementation logic of remote tripping and closing: linkage of three core elements

Remote control is not the function of a single electricity meter, but the collaborative result of a complete system, and all three components are indispensable:

Hardware foundation of smart meters: The meter is equipped with a built-in magnetic holding relay (equivalent to an electronic switch), which is the core component for executing the "trip" (power-off) and "close" (power transmission) actions, and can accurately respond to instructions to complete circuit on-off.

Communication network transmission channel: The electricity meter is connected to the background through communication technologies such as NBIoT, 4G, RS485, etc., and transmits instructions like a "telephone line" - the operation instructions of the management platform can be delivered to the electricity meter in real time, and the response speed is usually within a few seconds.

Backend management platform center: Administrators send instructions (such as "Power outage in Room 201 of Building 3") through computer systems or mobile apps. The platform encrypts the instructions and issues them. After the electricity meter receives and verifies them to be correct, the operation is immediately executed, and the entire process can be traced.

2、 The core application scenario of remote tripping and closing

This function goes far beyond "power outage due to overdue fees" and has been extended to the entire process of apartment management, solving multiple traditional pain points:

functional type

Specific application scenarios

Management Value

Automatic control of arrears

Prepaid users will automatically trip when their balance is reset, and will automatically close after recharging

Eliminate overdue payments without the need for manual collection

Rental management assistance

One click power outage upon termination of lease, remote power supply for new tenants upon check-in

Simplify the handover process to avoid ineffective power consumption of vacant houses

Security risk isolation

Detected illegal high-power electrical appliances (such as electric heating rods) automatically tripping

Prevent electrical fires and improve the safety level of apartments

Batch efficient operation

Batch power outages for vacant apartments during holidays, one click power supply during the new school season

Reduce labor costs and achieve energy-saving control

Special scenario protection

Lock the dormitory power supply during the exam period (power protection mode)

Prevent accidental power outages and ensure special needs are met

3、 Control logic under different payment modes

The triggering method for remote tripping and closing varies depending on the payment mode, but the core is automatically controlled by the system:

Prepaid model (mainstream for apartments):

Users recharge through WeChat, Alipay and other channels, and the amount is synchronized to the management platform in real time;

When the remaining battery level/amount is below the set threshold (such as 10 yuan), the system will automatically send SMS/WeChat reminders;

After the balance is exhausted, the platform immediately issues a trip command and the electric meter relay is disconnected;

After the user recharges, the system detects that the balance is sufficient and automatically triggers the closing to restore power supply, without the need for manual intervention throughout the process.

Post payment mode (applicable to a few apartments):

The system automatically reads meters and generates bills on a monthly basis, and sends collection notifications if overdue payments are not made;

After a certain period of delay (such as 15 days), the administrator can manually trigger or the system can automatically perform remote power outage;

After the user pays the fee, the platform manually or automatically sends a closing command to restore power supply.

4、 Security and reliability assurance

The core concerns of remote control, such as "misoperation" and "being attacked by hackers", have been addressed through multiple protection mechanisms:

Instruction encryption transmission: Communication data uses encryption protocols to prevent instructions from being intercepted or tampered with;

Hierarchical control of permissions: Only administrators have operational permissions, ordinary personnel can only view data, and critical operations require secondary verification (such as SMS verification codes);

Record the entire operation process: every trip and closing is recorded with the operator, time, and reason, which can be traced at any time;

Hardware lifespan guarantee: The relay design has a lifespan of over 100000 times, and frequent operation during daily use can also meet long-term needs;

Emergency plan backup: If the network signal is poor and the instruction transmission fails, the backup switch can be manually operated through the meter box to ensure uninterrupted control.
