Embodiment Construction

[0017] Depend on figure 1 As shown, an intelligent data acquisition device with protocol solidification includes a main processor for converting bus control rights, and the main processors are respectively connected with a memory chip and a meter for collecting and analyzing data after receiving the bus control rights A protocol card and at least one communication interface circuit. Since the meter protocol card is used to collect and analyze data, if the smart meter connected by communication with the present invention replaces the protocol or increases the protocol table, then only the meter protocol card needs to be replaced to replace the protocol or increase the smart meter after the protocol table. The instrument performs data collection. In addition, due to the solidification of the protocol, the requirements for the data processing speed and memory of the main processor are greatly reduced. The number of the communication interface circuits is set according to actual ...

Abstract

The invention discloses an intelligent data acquisition device with a solidified protocol. The device comprises a main processor for converting the control power of a bus. The main processor is respectively connected with a memory chip, a meter protocol card for collecting and analyzing data after receiving the control power of the bus and at least one communication interface circuit. Due to the fact that the meter protocol card instead of the processor is employed to collect and analyze data, the communication protocol provided by the invention is matched with the communication protocol of an intelligent instrument by changing the meter protocol card to carry out data collection and analysis on the intelligent instrument. In addition, the meter protocol card is employed to collect and analyze data, so that the process of data collection and analysis is independent from the main processor, the program structure of the main processor is simplified, the burden of the main processor is reduced, debug is more easily to be carried out, and the stability and the reliability is greatly enhanced. The intelligent data acquisition device with the solidified protocol provided by the invention is widely applied in a centralized meter reading system.

Description

technical field [0001] The invention relates to electronic circuit technology, in particular to an intelligent data acquisition device with protocol solidification. Background technique [0002] At present, the centralized meter reading system is a system composed of intelligent terminal equipment and Internet of Things technology. There are various communication protocols, so that the data acquisition device needs to set corresponding different communication protocols for analysis, so as to communicate with the smart instrument corresponding to the same communication protocol. However, the current technology mainly adopts the communication protocol analysis system embedded in the software programming of the processor to analyze different communication protocols. A large number of codes lead to complex software structure, a lot of resources, and a large CPU load during parsing, and it is difficult to debug. Contents of the invention [0003] In order to solve the above-m...
