An implementation method for debugging power collection terminals and obtaining meter reading information

Abstract

The invention discloses a realization method for debugging an electric power acquisition terminal and obtaining meter reading information. The method comprises the following steps: 1, preparing a PC host, an emulator and the electric power acquisition terminal; 2, connecting one end of the emulator with the JTAG interface of the electric power acquisition terminal, and connecting the other end of the emulator with the PC host; 3, constructing a data storage structure in the RAM of the electric power acquisition terminal, storing meter reading information to be acquired by the PC host in the data storage structure, and creating multiple virtual serial ports TTY; 4, creating multiple virtual serial ports COM corresponding to the multiple virtual serial ports TTY in a one-to-one manner on the PC host, and establishing communication between the multiple virtual serial ports TTY of the electric power acquisition terminal and the multiple virtual serial ports TTY on the PC host to realize data interaction; and 5, accessing the multiple virtual serial ports TTY by the PC host to realize real-time reading of the meter reading information stored in the data storage structure. The method realizes meter reading in the debugging process without increasing external hardware interfaces of the electric power acquisition terminal.

Description

technical field [0001] The invention relates to a realization method for debugging a power collection terminal and obtaining meter reading information. Background technique [0002] Existing power collection terminals have few external hardware interfaces, commonly used interfaces include RS232 interface and RS485 interface, debugging operation and meter reading operation cannot be carried out at the same time, this type of power collection terminal will increase the workload of on-site operators; secondly , the current means of debugging and upgrading is also through the above-mentioned RS232 interface and RS485 interface to realize the information interaction between the PC and other external equipment and the power collection terminal. Disadvantages of this method: 1. Occupies one serial port hardware resource, that is, this type of serial port cannot be used as a normal meter reading (abnormal working state) during the debugging process; 2. This type of serial port canno...

Problems solved by technology

[0002] Existing power collection terminals have few external hardware interfaces, commonly used interfaces include RS232 interface and RS485 interface, debugging operation and meter reading operation cannot be carried out at the same time, this type of power collection terminal will increase the workload of on-site operators; secondly , the current debugging and upgrading method is to realize the information interaction between PC and other external equipment and power collection terminal through the above-mentioned RS232 interface and RS485 interface

Disadvantages of this method: 1. Occupies one serial port hardware resource, that is, this type of serial port cannot be used as a normal meter reading (abnormal working state) during the debugging process; 2. This type of serial port cannot be reused (debugging mode / message mode); 3. The reading speed of this type of serial port memory is low, which cannot meet the interaction of large amounts of data, which affects real-time performance; 4. The hardware design needs to consider debugging the serial port
