The Research And Design Of Linux-based Electricity Collection Terminal

As the economy continues to grow and the standard of living of the people continues to improve,the demand for electricity for business and production is also increasing.This has prompted the power grid and related enterprises to continuously improve the service level of power generation,transmission and energy metering.Electric energy acquisition terminal can realize the requirements of electric energy data transmission,storage and electric energy measurement,and is an important equipment for electric energy measurement in power plants,substations and large power users.However,the data confidentiality of existing electric energy acquisition terminals is weak,and there is a risk of data leakage,which will cause huge economic loss once the data is stolen.In this dissertation,it redesigns the electric energy acquisition terminal of a power grid to improve its operation performance and data confidentiality.Firstly,the main control chip of the electric energy acquisition terminal is selected,and the hardware circuit is designed for the development requirements of the terminal,including power supply module,downlink communication module and uplink communication module,etc.Then,based on the hardware platform and design requirements,the terminal software is designed: for the uplink communication module,the code flow of configuration information import function and master station communication is designed;for the uplink communication function,the communication flow between the terminal and the upper computer is designed.For the communication encryption problem when the terminal communicates with the host computer through the network,it analyzes the application scenarios,advantages and disadvantages of different algorithms in modern encryption algorithms and determine the communication encryption scheme to ensure the security of information;for the downlink communication module,it selects the communication mode,design and implement the database,and carry out the program design.Finally,by establishing hardware and software test platforms and conducting hardware and software tests,the test results show that the designed electric energy acquisition terminal has improved operational performance and data confidentiality.
