What is the biggest fear of smart meters - the nemesis of smart meters

1、 Electromagnetic interference: disrupting signal transmission and measurement accuracy
Interference principle: Smart meters transmit data through electromagnetic signals. If there are high-power electrical appliances (such as induction cookers, industrial motors), wireless devices (such as walkie talkies, base stations), or high-voltage lines around them, the electromagnetic radiation generated may interfere with the internal sensors and communication modules of the meter.
Specific impact:
Measurement error: Electromagnetic interference may cause inaccurate meter readings, such as underestimating or overestimating actual electricity consumption, affecting electricity bill settlement.
Communication interruption: Remote meter reading, remote control and other functions may fail due to signal interruption, causing the power company to be unable to obtain user electricity data in a timely manner.
Equipment damage: Long term exposure to strong electromagnetic environments may cause damage to electronic components inside the meter due to overheating or voltage fluctuations.
Case: Due to the addition of a wireless base station nearby, some smart meters in a certain factory showed abnormal readings, which were detected to be caused by electromagnetic interference. The problem was later solved by installing shielding devices.
2、 Physical interference: directly damaging the structure and data of the electricity meter
Interference principle: Smart meters are usually installed inside the meter box. If the meter box is damaged by human activities (such as prying locks or impacts) or external impacts (such as vehicle collisions or accidental touches during construction), it may directly damage the meter hardware or cause data loss.
Specific impact:
Electric meter damage: The outer shell is broken, the internal circuit is broken, or the components are detached, causing the electric meter to malfunction.
Data loss: Electricity usage records, user information, and other data stored in the meter may be lost due to physical impact, affecting electricity billing and analysis.
Safety hazards: Damaged electricity meters may cause safety accidents such as short circuits and fires, posing a threat to the safety of users' lives and property.
Case: Due to malicious damage to the electricity meter box in a certain residential area, multiple households' electricity meter data was lost. The power company needs to reinstall the electricity meters and restore the data, causing unnecessary trouble and losses.
3、 Network security threats: tampering with data and control permissions
Interference principle: Smart meters communicate with power companies or user terminals through the network. If there are network vulnerabilities or hacker attacks, it may cause meter data to be tampered with or control permissions to be stolen.
Specific impact:
Data tampering: Hackers may modify meter readings, resulting in abnormal electricity bills for users (such as overcharging or underestimating), or conceal illegal electricity usage behavior (such as electricity theft).
Control permission theft: Hackers may remotely control the electricity meter, implement power outages, restore power supply and other operations, affecting the normal use of electricity by users.
Privacy leakage: The user's electricity usage habits, household routines, and other information stored in the electricity meter may be stolen and used for illegal activities (such as precision fraud).
Case: A smart meter was hacked in a certain region, resulting in abnormal meter readings for some users. The power company solved the problem by strengthening network security protection measures.
