Abstract

A hardware-in-the-loop detection system for software reliability and safety of acquisition terminal is disclosed, in accordance with that present invention, the hardware-in-the-loop detection system for software reliability and safety of the acquisition terminal provided by the invention, the program of the terminal is downloaded to the control chip of the acquisition terminal, sending a peripheral program of the detected acquisition terminal to the FPGA simulation module through the host computer, FPGA simulation module control that channel selection conversion module through 485 circuit control MCU, Then, the host computer sends commands to the FPGA simulation module to make the FPGA simulation module simulate the peripheral equipment of the acquisition terminal, so as to simulate various peripheral equipment to verify the accuracy of the program in the control chip of the terminal, and at the same time, it can detect the reliability of the acquisition terminal software which has been working for many years. The invention does not need the program provided by the manufacturer, and only the chip for downloading the program can be detected, so as to protect the core interests of the manufacturer.

Description

technical field [0001] The invention relates to the technical field of software verification, in particular to a semi-physical detection system for the reliability and safety of acquisition terminal software. Background technique [0002] The key work in the detection of collection terminals is to test the functions of collection terminals. With the deepening and application of collection functions, the requirements for collection terminal functions are becoming more and more extensive. The application of data collection is not limited to metrology. The acquisition terminal inspection is mainly divided into full performance inspection before delivery and random inspection after delivery. During the random inspection after delivery, it is often found that the acquisition terminal program supplied by the manufacturer is inconsistent with the one that passed the pre-delivery inspection. However, these problems must be found one by one. The step-by-step test of each function res...
