On-line meter reading system and method thereof

Abstract

The invention discloses an on-line meter reading system and a method thereof; wherein, the system comprises a remote meter reading host computer, a plurality of gauges, a plurality of meter reading branch computers; the gauges use the same or different codes; the meter reading branch computers are used to forward data information transmitted between the remote meter reading host computer the gauges; each meter reading branch computer is connected with at least one gauge; the remote meter reading host computer is used to read data information of the gauges. The remote meter reading host computer comprises a memory which is used to store correspondence addresses of the meter reading branch computers, identification numbers of the gauges under the meter reading branch computers, corresponding meter code identifications, meter correspondence addresses of the gauges. The remote meter reading host computer is internally provided with communication and data processing modules corresponding to the codes of the gauges, which are used to generate meter reading request frame regarding the meter codes used by the gauges, simultaneously receive return frames returned by the gauges and analyze the data information of the gauges based on the return frames. The system and method of the invention can lower complexity and working load in software upgrading and maintenance of the on-spot meter reading device.

Description

technical field [0001] The invention belongs to the technical field of intelligent control, and relates to a meter reading system and method, in particular to an online meter reading system and method. Background technique [0002] The existing remote meter reading system generally consists of a meter reading master station and a large number of on-site meter reading terminals. The communication protocols of the smart watt-hour meters on the power supply site are different due to the different models, manufacturers, and installation years. There are often dozens or even dozens of watt-hour meter protocols in one area. In order to solve the problem of reading meters with different protocols, the current remote meter reading mode is to integrate the meter reading software modules of all types of meters into the meter reading terminal software. When the terminal is installed, the meter number, protocol type, and meter communication address of the meter are set in the terminal ...

AI Technical Summary

Problems solved by technology

This mode of expanding the type of meter reading based on hardware space is bound to be limited by the storage capacity of the terminal hardware, and it also increases the complexity and cost of the terminal hardware.

[0005] 2. Every time a new meter protocol is added, the terminal software must be modified. During this process, frequent modifications may affect the stability of the terminal software.

[0006] 3. All meter reading functions are implemented on the terminal side. Once the meter reading function needs to be updated, the on-site terminal software must be upgraded, which will increase the workload of later maintenance.
