DT6 (DX) voltage and current monitoring device

1. Product use

The voltage and current monitoring embedded software V1.10 is mainly aimed at the development and application of three-phase voltage and three-phase current data monitoring, statistics, query, regular reporting, and real-time event reporting for the practical application of the Beijing power supply section.

2. Main functions and performance requirements

2.1 Basic functions

2.1.1 Collection and statistics objects

Adopt the true effective value algorithm based on Fourier transform, sampling 5~10 cycles per second, each cycle has 256 sampling points.

Real-time collection and display of 1~3 channels of 100V or 220V or 380V voltage, and use the minute average as the smallest statistical unit for data statistics, storage and display.

Real-time acquisition and display of 1~3 channels of 1A or 5A current.

2.1.2 Statistical form

Automatically classify statistics by day and month (only for voltage).

2.1.3 Statistics and record items

2.1.3.1 Voltage data

Record the actual operating voltage, including the generation time of the 1min voltage average value and the 1min voltage average value.

2.1.3.2 Voltage monitoring statistics

Divided into daily statistical data and monthly statistical data, the data is based on the actual operating voltage (1min voltage average value) and the monitored voltage rating, upper and lower limits to determine the statistics, including the maximum voltage and the time of occurrence, the minimum value and the occurrence Twelve items including time, voltage average value, over-upper limit rate and over-upper limit time, over-lower limit rate and over-lower limit time, voltage pass rate and pass time, and statistical time.

2.1.3.3 Current data

Record the actual operating current, currently only the real-time current content is displayed.

2.1.3.4 Event Record

Divided into sampling voltage outage, upper limit and reset, lower limit and reset, monitor reset event and monitor power outage event, etc., according to the judgment principle of each event, including the time of the event or the current 1min voltage average value. Item content.

2.1.3.5 Flow Record

Divided into monthly sending and monthly receiving traffic, monthly statistics, including traffic value, unit: Byte.

2.1.3.6 Reliability record

Monthly statistics, including the number of power outages, the longest outage time, the shortest outage time, and the total outage time.

2.1.3.7 Work status record

Divided into total working time and this continuous working time, including the amount of time, unit: hour.

2.1.4 Setting of the turning month day

The default natural month for monthly statistical data is the statistical time. You can set any day from the 1st to the 28th as the monthly statistical settlement date. The monthly statistical time is from 0:00 on the monthly statistical settlement day to 0:00 on the monthly statistical settlement day of the next month.

2.2 Data storage function

Save the actual operating voltage (1min voltage average value) monitored in the last 100 days or the current month or last month (optional), with a minimum interval of 1min.

Save the daily statistical data of the voltage monitoring for the last 100 days or the current month or last month (optional);

Save the monthly statistical data of voltage monitoring in the last 12 months or the current month and last month (optional);

Save up to 1440 times of voltage over-limit and over-limit reset event records per day in the last 100 days or the current month or last month (optional);

Save up to 64 power outages and incoming calls per day in the last 100 days or the current month or last month (optional);

Save the monthly data traffic sent and received within the last 12 months (unit: Byte);

Save the continuous running time and accumulated running time (unit: hour) after each reset.

Keep reliability records for the last 2 months.
