Problems solved by technology

However, the existing concentrators do not have the interpretation and inspection of the agreement. In addition, there is no national or provincial unified agreement inspection agency, and manufacturers have different interpretations of the agreement itself. As a result, there are various protocols for smart meter reading at present, including CJ188- 2004, DLT645 / 97 and other various protocols, even under the same protocol, the order of data transmission is different, and the difference in the return of electrical parameters is even greater, so a concentrator cannot be compatible with water meters, electricity meters and gas meters. Watches and other different watches, and cannot be compatible with different watch models under the same watch category, or even well compatible with watches made by different manufacturers under the same watch model

Embodiment 1

[0031] like figure 1 As shown, in this embodiment, the server is remotely connected to the concentrator, wherein the concentrator is connected to various types of meters through the Mbus meter reading bus. Before receiving the meter reading task from the server, add the class number and feature code to the concentrator, where the class number and feature code can be set as numeric values, characters or strings, and set the rules of the feature code, including corresponding rules and adjustment rules , the corresponding relationship is the many-to-one or one-to-one mapping between the large and small category numbers, meter reading protocols and feature codes. After the setting is completed, the concentrator starts to receive the data frame sent by the server. After the concentrator decodes the data frame from the server, it assigns the meter reading task to the meter reading module under the concentrator. The meter reading module stores the meter reading task locally. When it...

Embodiment 2

[0033] like figure 2 As shown, the process of this embodiment is basically the same as that of Embodiment 1, but the difference is that the manufacturer code is added. Therefore, after the characteristic code is determined, when the meter reading port is initialized, the timeout time parameter of the next frame in the half-work mode can be set according to the specific meter. Set, and can not carry out the detection of the meter reading parameter length when adjusting the meter reading parameter, but directly the addition of the special address bit is set in the adjustment rule, thereby can save in communication and adjustment process compared with embodiment 1 more time.

Embodiment 3

[0035] like image 3As shown, the partial process of this embodiment is the same as that of Embodiment 1. The difference is that the pending codes are added and the feature codes are classified and sorted by the meter reading protocol, and the feature codes are determined by the size class number and the meter reading protocol. Add judgment, if the size class Number and meter reading agreement can determine feature code by corresponding rule, then follow-up process is identical with embodiment 1 (not shown in the figure), if can't satisfy corresponding rule, this big and small class number and meter reading agreement are determined as undetermined code, undetermined code Initially assign the first character code in the same list as the meter reading protocol under the meter reading task, and use the corresponding adjustment rules, in which the process of initializing the meter reading port, adjusting the meter reading parameters, and generating the meter reading frame through t...

Abstract

The present invention relates to a feature-code-based centralized meter reading method. The method comprises: size, type, and feature code information are added and a feature code rule is set, wherein the rule includes a correspondence rule and an adjusting rule; according to the size and type as well as a meter reading protocol, a feature code is determined based on the correspondence rule; and on the basis of the feature code adjusting rule, a meter reading port is initialized, a meter reading parameter is adjusted, and a meter reading frame is generated. According to the feature-code-based centralized meter reading method, on the basis of compatibility with different protocols and meters with different types by one concentrator, meter return data can be stored in one format; and a self-setting capability is realized. And optimization for meter communication from different manufacturers can be realized.

Description

technical field [0001] The invention relates to a data collection technology, in particular to a centralized meter reading method based on a feature code. Background technique [0002] In the field of water, gas and heat meter reading in public utilities, manual reading was used before. In recent years, automatic meter reading has gradually been realized by setting up a concentrator. And send data back to the control center or convey the command of the master control station to the meter reading controller. However, the existing concentrators do not have the interpretation and inspection of the agreement. In addition, there is no national or provincial unified agreement inspection agency, and manufacturers have different interpretations of the agreement itself. As a result, there are various protocols for smart meter reading at present, including CJ188- 2004, DLT645 / 97 and other various protocols, even under the same protocol, the order of data transmission is different, an...
