Description
Technical Field
The utility model relates to an electric power data acquisition technical field, more specifically say, it relates to a redundant data acquisition system.
Background
The power operation and maintenance service of the power distribution room, i.e. the power operation and maintenance service, needs to be based on the collected data.
The data acquisition process is carried out through the stages of manual inspection meter reading, RS 485-based field bus digital meter reading and the like.
Firstly, early manual inspection meter reading: the manual regular inspection mode is adopted, and the problems of low data precision, high labor cost, slow fault finding, difficulty in finding fault points and the like exist.
(II) digital meter reading based on a field bus:
the method is generally applicable to the scene of centralized installation of the electric meters, namely a meter reading mode that the electric meters are centrally installed in one meter box, such as a newly-built apartment, a newly-built residential community, a commercial complex and an office building, the electric meters of each layer of users are centrally installed in the electric meter boxes in the electric wells, and particularly in the apartment, the number of the users is large, the manufacturing cost is low, the construction is convenient, and the effect is good.
The method has the following specific advantages:
1. hardware cost is saved: the module does not need to be equipped, and communication can be connected only by the interface, so that the hardware cost is saved.
2. The performance is stable: the system adopts RS485 private line communication, can ensure 24h real-time communication every day, and interference immunity is strong, and data is online in real time, and is stable and reliable.
3. The centralized meter reading is particularly suitable for the power utilization management department with particularly high requirements on the recovery rate of the electric charge.
4. RS485 special line communication is adopted, meter reading speed is high, and anti-attack performance is strong.
There are disadvantages as follows:
1. the communication capacity of the bus is small, theoretically only allowing access to 32 devices at most, and is not suitable for the multi-user capacity requirement of building nodes.
2. The communication rate of the bus is low, and the common baud rate is 9600 bps. The speed has direct relation with the communication distance, and when the communication distance reaches more than hundreds of meters, the reliable communication speed is less than 1200 bps.
3. The chip power consumption is larger, the static power consumption reaches 2-3mA, the working current (sending) reaches 20mA, and if the bias resistor and the terminal resistor are added, the working current is larger. The line voltage drop is increased, which is not favorable for remote wiring.
4. The network formed by the bus can be wired only in serial, and cannot form any branch such as star. The serial wiring causes great difficulty for the actual wiring design and construction of the cell, does not follow the serial wiring rule, and greatly reduces the communication stability.
5. The electrical performance of the bus determines that the stability of the bus is poor in practical engineering application, and the impedance matching and other debugging of the network are needed in multi-node and long-distance occasions, so that the engineering complexity is increased.
6. The bus is usually not isolated, when a node on the network fails, the whole or part of the system is broken down, and the failure position is difficult to judge.
7. The bus adopts a host polling mode, so that the communication throughput is low, and the real-time performance is poor when the system is large.
In summary, the above methods cannot ensure high stability and reliability of data acquisition in both manual mode and RS 485-based bus mode under the requirements of ensuring stable operation and reliable maintenance of electric power.
