Infrared IC card single-phase electric meter

Infrared IC card single-phase electric meter

Infrared IC card single-phase electronic prepaid energy meter users must first purchase electricity through the infrared IC card and input it into the meter before the meter can supply power. One meter, one card, and the cards are not compatible with each other. After the power in the card is used up, it will automatically trip and cut off the power. Users must use the card again to purchase electricity and input it into the meter before they can continue to use it. Thus effectively solving the problem of difficult electricity collection fees. At the same time, users' electricity purchase information is managed by a microcomputer, making it easy to query, collect, charge, and print receipts.

The technical indicators of this product comply with the technical requirements of GB/T17215-1998 "Level 1 and Level 2 Static AC Active Energy Meters" and GB/T18460-2001 "Prepaid Energy Meters". It adopts the most advanced IC card technology and SMT process in China, with advantages such as dual display, accurate measurement, stable accuracy, secure confidentiality, reliable performance, complete functionality, low power consumption, and simple and convenient operation.

1. Using data voting error correction technology, each data is stored in five places. If there is an error in the data, it can be corrected in four other places, thus achieving absolute reliability and foolproof.

2. All internal components of the IC card electric meter are made of industrial grade branded devices, and key components are made of original chips from the United States and Japan, such as the AD7755 metering chip, to ensure the quality of the devices and the entire meter.

3. The non-contact IC card meter adopts patented technology to transmit data wirelessly, completely solving the problems of waterproofing, moisture resistance, and attack prevention.

4. Infrared IC card transmits data, with an effective card swiping distance of more than 3 meters, effectively solving the difficult problem of card swiping and recharging in special locations.

5. Prepaid function: When the power purchased by the IC card is used up, the power supply will automatically stop.

6. Using data voting error correction technology, each data is stored in five places. If there is an error in the data, it can be corrected in four other places, thus achieving absolute reliability and foolproof.

7. Capacity limiting function: The capacity limiting power can be set. When the load exceeds the capacity limiting power, the meter will automatically trip and alarm. After the overload load is disconnected, the card will be swiped to restore power supply.

8. Alarm function: Display an alarm when there is a remaining 100 degrees, power off alarm when there is a remaining 20 degrees, swipe the card to restore power supply, and promptly remind users to purchase electricity.

9. All internal components of the IC card electric meter are made of industrial grade branded devices, and key components are made of original chips from the United States and Japan, such as the AD7755 metering chip, to ensure the quality of the devices and the entire meter.

10. The infrared IC card meter adopts patented technology to transmit data wirelessly, completely solving the problems of waterproofing, moisture resistance, and attack prevention.
