How To Ensure The Reliability of The Remote Meter Reading System？
Customers all hope to purchase a stable and reliable meter reading system, to avoid all kinds of troubles in use, and various businesses also publicize how stable and reliable their remote meter reading systems are. First, this is a one-sided statement. The reliable operation of the meter reading system is based on the quality of the instrument, data acquisition and communication equipment, and the reliability of the telecommunication signal, and it is possible to make the meter reading system operate reliably. Therefore, to solve the reliable operation of the meter reading system, first determine three elements: the quality of the instrument, the quality of the communication equipment, and the quality of the telecommunication signal.
1. Instrument quality
There are only a few domestic electricity meter brands with good quality, such as the State Grid Corporation of China and the electricity meter head supplier of China Southern Power Grid Corporation, whose quality has been verified by long-term reliability.
2. Reliability of communication equipment
There are two core factors for the reliability of communication equipment. One is to produce meter reading equipment with high reliability from large manufacturers. Second, the meter reading equipment cannot be connected to too many meters. The meter reading concentrator can generally support the meter reading of 1024 electric meters, but it does not mean that it is easy to use. If you want to ensure high reliability, it is recommended to reduce the number of meters connected to the meter reading concentrator to less than 200 meters. Such meter reading reliability is guaranteed.
3. Telecom signal reliability
Wireless telecommunication signals are reliable and stable. The problem is that in relatively deep basements and remote mountainous areas, the reliability of these wireless signals is poor, which will inevitably lead to frequent problems with the meter reading system. So how should we solve the problem? If the signal is poor, in fact, sometimes communication is possible, and sometimes communication is not possible. So, we must have a mechanism to find out the law of signal strength. That is, when the signal is strong, the operation of the meter is completed. For example, if the electricity meter is in arrears, it will not trip immediately. When the signal is strong, the tripping operation is performed, which facilitates the closing of the meter. Because once the meter is in arrears and trips, the user will immediately make a mobile payment operation. That is, the closing operation is also carried out almost at the same time. But for this series of operations, the meter reading system chose a better time to complete the operation.
