How Is the Accuracy of Remote Power Carrier Meter Reading?
There are many users who worry about the inaccuracy of power consumption data when using the power carrier meter reading system, which will affect their own interests. So, is the remote power carrier meter reading accurate? How to ensure the accuracy of data transmission? Next, this article analyzes the principle of carrier meter reading, power carrier communication, carrier meter and other aspects to answer your questions.
Is the power carrier remote meter reading accurate?
Power carrier is PLC, which is a unique communication method of power system. It is a technology of high-speed transmission of analog or digital signals through carrier mode.
Power carrier meter reading refers to a communication method based on microelectronics technology in a remote meter reading system. It organically combines computer network and carrier communication technology and uses existing power lines to read and transmit water and electricity meter data, a long-distance communication meter reading scheme.
The power carrier remote meter reading automatic meter reading accuracy rate is 100%. The speed is fast, and it is widely used in electric energy metering and management in various scenarios such as residential areas, factories, schools, shopping malls, and properties.
From the perspective of application scope and use effect, users of power carrier meter reading are more recognized, and the accuracy is very high.
How does the power carrier meter reading ensure the accuracy of data remote transmission?
In the application of the remote meter reading system, the power carrier meter reading communication network is composed of the carrier meter, the carrier concentrator and the master station meter reading system software. The carrier data transmission is divided into upper layer communication and lower layer communication. The quality of carrier communication directly affects the correctness and achievement rate of data meter reading.
1. Accurate data transmission through the wireless network TCP protocol function.
The upper layer communication is the communication connection between the carrier concentrator and the main station, and the data transmission is realized accurately through the TCP protocol function in the GPRS/CDMA wireless network mode. The TCP protocol is a connection-oriented, reliable, byte stream-based transport layer communication protocol. Only the value sent and received can be judged as valid data. Therefore, in general, the data will not be communicated incorrectly.
2. The carrier power meter uses multiple binary bytes for power line communication through the carrier chip to ensure the correctness of the data.
The lower-level communication is the communication connection between the carrier meter and the carrier concentrator, which directly uses the power line carrier communication method to collect and transmit data to the concentrator. The most critical issue here is the accuracy of the carrier meter reading.
A carrier meter is an electric energy meter with a built-in carrier chip with the function of carrier meter reading. The carrier chip outputs data information to the low-voltage power line to realize remote automatic meter reading through carrier communication.
Generally speaking, as long as the running word of the meter is normal and correct, the communication data is correct. Because multiple binary bytes are used for communication in the instrument, the feature of transmitting a parameter in multiple bytes can effectively ensure the correctness of the data.
In addition, the data transmission has a verification function. Only when the data value sent by the meter is consistent with the value calculated by the system will it be judged as valid and correct data.
