Caimore DTU for remote monitoring solution for power distribution network based on

1. System industry background

The construction of the power grid is complex and huge, with a large time span, and various new and old equipment are mixed in it. Many power grid architectures no longer meet the needs of today's social development, but the cost of power grid transformation is huge and it is not a matter of overnight. In the event of natural disasters and other unknown damages , it will pose a serious threat to the normal operation of the optical cable, and even the line will be interrupted. Rush repair work is also extremely difficult and time-consuming, which will have a serious impact on the safety of the power grid and the normal operation of the equipment.

To improve power quality nowadays, from the source, it is to combine power grid transformation with the construction of new power grids. For the newly constructed power grid, it is necessary to make reasonable planning first, and use the latest science and technology to promote the network construction of power distribution network automation.

2. The system topology

In response to the problems in the power industry, Xiamen Caimore Technology Co., Ltd. relies on its rich experience in the Internet + industry and rich network products to build a set of basic solutions based on Internet + for the power distribution network industry market to achieve power Intelligent distribution network effectively solves the problem of efficient, stable and fast transmission of power data services

3. System architecture

The entire system application can be divided into three parts, collection terminal, communication terminal, and communication center.

 

(1) Acquisition terminal: mainly intelligent ring network cabinet, mainly including primary circuit, secondary circuit, switch cabinet, load switch, transformer, relay, contactor and other equipment

 

(2) Communication terminal: using Xiamen Caimore’s DTU, the data of the customer’s collection terminal’s power equipment can be reported to the communication center through the 2/3/4G network, and at the same time, it can also receive telemetry, remote signaling, and remote control signal pairs from the communication center. The terminal equipment is controlled.

(3) Communication center: Through the access of Caimore 2/3/4G DTU wireless transmission terminal, the staff of the monitoring center can view the operating status of each device in real time, and can remotely perform remote measurement, remote signaling, and remote control. If any equipment fails, you can immediately determine the point of failure and send someone to maintain it.

 

4. The program advantages

Features:

(1) The appearance is small and exquisite, the installation is simple, accord with the industrial grade product design.

(2) Support multiple serial ports RS232/485, TTL.

(3) Support multiple network standards, compatible with 2/3/4G networks.

(4) Support platform management, remote operations such as upgrade, configuration, restart, etc.

(5) High communication stability. Caimore DTU products have passed strict electromagnetic compatibility tests. Stable work satisfies -35℃~75℃.

(6) Reduce deployment costs and effectively solve the difficult problem of light deployment and construction.

(7) SMS operation, SMS control device restart, SMS configuration device parameters.

5. Program summary

The intelligent power distribution network system provides users with a guarantee for power quality and power supply reliability. By adopting distribution network automation solutions, power outages can be reduced, and the service level of power supply companies can be improved, adding vitality to the lives of the masses.

 

The intelligent power distribution network system solves the problem of backward grid structure. It is one of the mature application solutions of Xiamen Caimore DTU, which can be widely used in urban heating, intelligent traffic management, petroleum and other industries.
