Embodiment Construction

[0025] Such as figure 1 As shown, a transmission system for error data of an electric energy meter verification device includes a host computer and a plurality of error machines on the electric energy meter verification device. The I / O ports of the error machines are connected to the extended I / O ports of the upper computer. At this time, the upper computer queries the error data without querying the error machine through the serial port. It only needs to query the corresponding hardware flag through the extended I / O port. Only when the hardware flag is low, the direction error machine reads the error data. This structure ensures that every communication between the upper computer and the error machine is effective, and the expected data can be obtained, avoiding the blind "disturbance" of the error machine by the common serial communication method, so that the error machine is always in a "quiet" work status.

[0026] Optimally, the extended I / O port of the host computer is ...

Abstract

The invention belongs to the technical field of data transmission, and particularly relates to a transmission system and method for error data of an electric energy meter calibrating device. The system comprises an upper computer and a plurality of error machines on the electric energy meter calibrating device, and I / O ports of the error machines are connected with an extended I / O port of the upper computer. The method has the advantages that the upper computer inquires the error data, the error data does not need to be inquired to the error machine through a serial port, only the corresponding hardware flag bit needs to be inquired by expanding the I / O port, and the error machine reads the error data only when the hardware flag bit is low.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and in particular relates to a transmission system and method for error data of an electric energy meter verification device. Background technique [0002] With the continuous popularization and application of smart energy meter verification devices in power systems, it is necessary to achieve high real-time performance in the process of monitoring multi-meter electric energy meter verification devices, especially in serial communication. Real-time communication, to read and process error data in time, and feed back the data. Realize the real-time control of the multi-meter electric energy meter device by the computer through the serial port communication, the accuracy, safety and reliability of the electric energy metering data transferred to the computer by the intelligent electric energy meter verification device, and the fast and efficient transfer of the electric energy meter data ...
