Product Introduction

The centralized meter reading system and its terminal products are suitable for three-phase general industrial and commercial users, single-phase general industrial and commercial users, residential users, and public transformer metering points. The core component of the system is the centralized meter reading terminal, which can collect data from low-voltage side users' energy meters, monitor and measure abnormal electricity consumption, and manage and remotely transmit the collected data.

The State Grid Type I intelligent simulation concentrator is used as a training function and has special teaching functions. It can set terminal error parameters, simulate terminal operation faults, and set terminal anomalies through the internal terminal. The setting of terminal fault points is set by the control PC software through TCP/IP, and it has terminal parameter editing function in conjunction with the fault setting software.

　Product features/main functions

● Terminal communication failures: Terminal not online (poor signal strength), Ethernet module failure, unstable installation of SIM card, SIM card damage, poor contact of communication module, abnormal GPRS communication;

● Terminal parameter faults:

● Terminal uplink communication parameter errors: main station IP address error, main station port number error, terminal IP address error, terminal administrative area code error, terminal address error, terminal uplink communication protocol error;

● Terminal downlink communication parameter error: The information of the terminal measurement point and the energy meter under the measurement point are inconsistent, the communication address of the energy meter under the measurement point is inconsistent with the actual corresponding energy meter address, the communication baud rate of the energy meter under the measurement point is inconsistent with the meter baud rate, the communication protocol of the energy meter under the measurement point is inconsistent with the meter communication protocol, and the access circuit of the energy meter under the measurement point is inconsistent with the actual access circuit of the meter;

● Terminal hardware faults: Terminal does not start, terminal white screen, terminal black screen, terminal flower screen, terminal AC phase A, B, C no voltage, terminal AC phase A, B, C no current, terminal AC phase A, B, C abnormal voltage, terminal AC phase A, B, C abnormal current;

Adopting the industrial grade ARM9 series system as the main LINUX operating system.

Excellent electromagnetic compatibility performance, able to resist interference from high voltage spikes, strong magnetic fields, strong static electricity, lightning surges, and has a strong range of environmental adaptability.

The uplink communication with the main station adopts public network mode and is compatible with communication methods such as GPRS/CDMA.

Downward communication can use low-voltage power line carrier, low-power wireless, or 485 bus communication.

The wide voltage range design makes it more reliable and adaptable to the working environment.

● Easy maintenance: With powerful configuration functions, device parameters can be easily modified locally/remotely, and online software upgrades are supported.

Main technical parameters

Typical applications

The DJTZ23-YBFD101 intelligent simulation concentrator is widely used in online loss training, equipment management, low-voltage data collection and other training equipment. At the same time as centralized meter reading, it completes functions such as monitoring and data statistics of distribution transformers in the substation area, and cooperates with the main station system to form a remote centralized meter reading system for electricity automation. This has positive significance for training and research on how to improve the efficiency of centralized meter reading in residential areas and reduce line losses.
