Method for calculating software time consumption of a flight control computer

Abstract

The invention relates to a method for calculating software time consumption of a flight control computer, which comprises the following steps of: setting a time consumption precision timer and a cycletask timer and enabling the timer; the cycle task start flag of the cycle task timer is set to '1', the main program of the flight control computer software is started to run, and the accumulative time consuming number of this cycle is cleared to zero; the accumulative number of time-consuming time in the current cycle is accumulated; at the end of the main program, the cycle task of the cycle task timer is identified as '0'; and the step of calculating the time-consuming of the flight control computer software for this cycle is carried out. The method of the invention does not change the hardware environment of the integrated control computer and the logic structure of the flight control software, and the time consumption of the flight control software cycle is accurately calculated in real time, and the time consumption of the real-time monitoring cycle can be monitored through the data recording device. The method has the advantages of high versatility, flexibility, easy use, goodexpansibility and high reliability.

Description

technical field [0001] The invention belongs to the technical field of flight control computer software design, and in particular relates to a time-consuming calculation method for flight control computer software. Background technique [0002] Cycle time consumption is an important performance index of flight control software reliability design and safety design. In the process of flight control software development, software development requires clear requirements for its cycle time consumption. During the development of flight control software in the past, there was a lack of effective means to calculate cycle time and real-time performance. [0003] There are two traditional time-consuming calculation methods for the flight control software cycle: [0004] Method 1: Set channel I discrete signal high-level output at the beginning of the flight control software cycle, and set channel I discrete signal low-level output at the end of the flight control software cycle; moni...
