Qingdao Qingbiao single-phase intelligent cost control electricity meter adopts the State Grid protocol, which can realize card insertion electricity sales (sub model DDZY2026C-RS485), remote electricity sales through RS485 network wiring (sub model DDZY2026C-RS485, suitable for centralized installation, requiring wiring), or 4G wireless remote prepaid electricity sales (sub model DDZY2026C-4G, suitable for decentralized installation). Its main functions are as follows:

1: State Grid standard, IC card local fee control, pay first, then use electricity;

2: Built in load switch, voltage 220V, current 5 (60) A;

3: DDZY2026C-RS485: RS485 remote prepaid (low-voltage wiring after centralized installation), IC card used as power transmission management card in emergency situations;

4: DDZY2026C-4G: 4G remote prepaid (can be used for communication after installation), IC card can be used as a power transmission management card in emergency situations;

5: Can be charged at 4 or 5 rates (total, peak, flat, valley, deep valley);

6: It is possible to remotely modify electricity prices and time of use settings;

7:Having time-sharing or5 tiers, 6 electricity pricesThe patternStep by step electricity pricing billing function;

8:The recharge amount is written into the energy meter and can be exchanged with the backend of the electricity sales system for datacomparison.

9: Superinstruction fetchingThe data block related to prepaid information shall at least include the following contents:Total electricity consumption, peak electricity consumption, off peak electricity consumption, off peak electricity consumption, valley electricity consumption,Deep Valley Electricity,Accumulated purchase amount, current purchase amount, remaining amount, overdraft amount, current electricity price, alarm amount, overdraft threshold amount, hoarding threshold amount, etc.Instantaneous data block: Aeach otherVoltage, Aeach otherelectric current,Zero line current, Aeach otherActive power, Aeach otherPower factor;

10: When recharging remotelyhaveElectricity purchaseRevocation function: By giving instructionsRemote rechargeThe sales amount of electricity and the function of recalling from the meter;

11: Can achieve postpaid remote closing and opening function;

12: The communication protocol adopts DLT645-2007, remoteDuring the electricity sales process, State Grid DES encryption technology is used,Accepting third-party programming applications, the manufacturer provides open-source communication protocols.

13: Can be matched with Qingdao Qingbiao Energy Management System software to achieve:

131. Computer card free remote recharge (computer does not require internet access, equipped with 4G devices to connect to computer), no fixed IP or cloud server required;

13. 2 The remote recharge of computers without cards and mobile phone WeChat official account needs to be configured with ECS.

All software is independently developed, without third-party control, and can run for a long time without any malfunctions.
