Problems solved by technology

[0006] Cons: Not enough scalability
[0009] Disadvantage: It is necessary to convert all blocking operations into asynchronous operations
One is to bring programming complexity, asynchronous operations need to be managed by the developer to explicitly manage the status information and execution history of the application
The second is that many widely used function libraries are difficult to implement with asynchronous operations. Even if they can be implemented with asynchronous operations, it will further increase the complexity of programming.

Abstract

The invention discloses a water meter remote reading system based on GPRS and a realization method for the system. An SPSERVER framework realizes concurrent meter reading. Each piece of DTU equipmentis dispatched to an SP_handler through socket connection. The DTU equipment is connected with the SP_handler according to fd of the socket connection and difference of card numbers of the DTU. All behaviors and methods of the DTU are mapped to the SP_handler. Through utilization of software, wired meters and wireless meters are organically gathered together in networking and data reading modes. Acollection process is simple. A program structure is clear. Convenience and application are facilitated.

Description

technical field [0001] The invention relates to the field of water meter reading, in particular to a GPRS-based water meter remote meter reading system and a method for realizing the system. Background technique [0002] With the development of embedded technology, the traditional remote meter reading system is facing challenges. How to quickly and accurately copy water meter data and realize remote transmission is a hot research topic in the field of industrial automation. This system analyzes the advantages and disadvantages of various remote meter reading schemes at home and abroad at this stage, and proposes a scheme based on GPRS for remote meter reading, because the system technology is relatively advanced and the software is powerful. The advanced water meter remote reading system has more practical significance. The system is mainly composed of GPRS and collector (acquisition terminal). The collector reads the water meter data through M-BUS bus or wireless module, ...
