Remote reading method based on electric low-voltage meter reading system

Abstract

The invention provides a remote reading method based on an electric low-voltage meter reading system. The remote reading method comprises the steps that S1, a channel converter starts wireless monitoring; S2, a concentrator sends a meter reading frame; S3, whether the meter reading frame is a standard DLT645 or not is judged, if so, the step S4 is executed, and if not, the step S5 is executed; S4, the meter reading frame is directly forwarded to an electricity meter through RS-485 and the step S9 is executed; S5, the meter reading frame is converted to a standard T188 protocol, a meter address is extracted, and the step S6 is executed; S6, whether the meter address is registered or not is judged, if so, the step S7 is executed, and if not, the step S8 is executed; S7, the meter address is forwarded to a water meter, a gas meter or a heat meter through a wireless interface, and the step S9 is executed; S8, the meter address is forwarded to the water meter, the gas meter or the heat meter through an M-BUS interface, and the step S9 is executed; S9, waiting is executed for 2 seconds, a response message is received, and the step S10 is executed; S10, whether response is produced or not is judged, if not, the step S2 is repeated, and if so, the step S11 is executed; S11, whether the protocol of the response message is the standard T188 protocol or not is judged, if so, the step S12 is executed, and if not, the step S13 is executed; S12, the protocol of the response message is converted to an extended DLT645 protocol, and the step S13 is executed; S13, the protocol of the response message is directly forwarded to a corresponding communication interface.

Description

technical field [0001] The invention relates to a remote copying method based on an electric low-voltage centralized copying system. Background technique [0002] Recently, the country has successively issued a series of documents, the construction of smart cities has been significantly increased, and new requirements have been put forward for the construction of intelligent energy utilization systems. The integrated collection of electricity, water, gas, and heat meters is an inevitable requirement for resource-intensive co-construction and the construction of a conservation-oriented society. At present, the low-voltage centralized meter reading system of the power system has been widely popularized and gradually perfected, while the centralized reading of water, gas and heat meters is in the ascendant, and the centralized meter reading systems of various meters are independent and incompatible with each other. [0003] At present, there is a wireless four-meter centralize...

AI Technical Summary

Problems solved by technology

The disadvantage of this solution is that the on-site non-wireless communication centralized meter reading system cannot realize the reading of compatible water, gas, and heat meters, and the water, gas, and heat meters of the M-BUS interface cannot be compatible with the wireless centralized reading system.

For the non-wireless centralized meter reading system and water, gas, and heat meters, if it is necessary to realize the centralized reading of four meters, the communication channel needs to be replaced, and the transformation workload is huge
