Problems solved by technology

[0004] However, because this standard system is completely incompatible with the current domestic regulations and agreements, once it is popularized and applied, it will inevitably cause a large number of electric energy meters currently in use to be scrapped, resulting in a huge waste of resources

Embodiment Construction

[0027] Such as figure 1 As shown, the protocol converter is used as an independent module between two systems with different protocols (IEC62056 and DL / T645), so that normal data exchange can be carried out between the two systems. Depend on figure 1 It can be seen that the protocol converter has two communication ports, one is used to communicate with the meter reading device or system conforming to the IEC62056 standard, and the communication protocol adopts the DLMS specification; the other communication port communicates with the electric energy meter, adopting the standard DL / T645 communication protocol.

[0028] see figure 2 , The protocol converter includes MCU, memory, power supply module, reset circuit, communication interface module and status indicator light. Wherein, MCU is the core of protocol converter, and protocol conversion system of the present invention just runs in MCU, and protocol conversion system has two asynchronous communication ports UART0 and UAR...

Abstract

The invention relates to a communication protocol transformation system and protocol transformation process. The protocol transformation system comprises an UARTO module for receiving and sending data packets of IEC 62056 standard protocol; an IEC 62056 function module is a core module supporting the IEC 62056 protocol and constructed according to the IEC 62056 standard; main function of a protocol transformation module is to inquire the corresponding DL / T 645 identification in light of data identification of IEC 62056, and sends to a DL / T 645 function module; the main function of the DL / T 645 function module is to deal with DL / T 645 protocol-associated functions; an UART1 module is responsible for communication with a table meter end. The communication protocol transformer for electric energy counting and charging systems and meter reading systems provided by the invention is applied between two systems with different protocols that are the electric energy meters of DL / T 645 communication protocol and the meter reading system consistent with the IEC 62056 standard, enabling the two systems with different protocols can exchange for data normally.

Description

technical field [0001] The invention relates to a communication protocol conversion system used in electric energy metering, billing and meter reading systems and a protocol conversion process of the protocol conversion system. Background technique [0002] Due to its advantages of high precision, multiple functions, and data communication capabilities, electronic energy meters have been more and more widely used in electric energy metering and billing systems. During use, the electric energy meter needs to exchange data with the meter reading system through the communication channel, but often due to the large number of electric energy meter manufacturers selected in the metering and billing system, the complex models of electric energy meters, and various types of communication channels; in addition, most electric energy The meter communication protocol adopts the extended DL / T645 communication protocol, but these communication protocols are not uniform, the communication ...
