According to the need of the lamplight landing aid system for the helicopter on a warship, this paper puts forward a software plan on the basis of the hardware design, and takes corresponding measures which are aimed at the interference of the single chip computer in the system, for example, trapping technique, instruction redundancy technique and so on.

This paper presents some methods of software interference protection such as instruction retry, instruction redundancy, software trap, software watchdog and high-speed intercept in order to raise the reliability of monolithic processors system.

In this paper,according to MCS-51 single chip microcomputer system,we have researched its software about anti-interference technique,and have discussed its realization of anti-interference technique,such as software trap,software watchdog,startup auto-check,and instruction redundancy.

This article discussed the mainly researchful question of the software anti-jamming technology,and analysed the general method of software anti-jamming which was used to the monolithic integrated circuit,which included the instruction redundancy,the interception technology and the watch-dog technology,and introduced the concrete realization method.

It is an important way to improve the reliability of electric control system by developing redundant technology.

This paper discusses functions,operation characteristics and control logic of the control system of an elevator type parking equipment and establishes reliability calculation model for the control system Since some element s MTBFs cannot meet design requirements,redundant technology is applied to improve the system reliability.

The reliability of mechanical equipment can be obviously raised when redundant technology is applied to the reliability design.

The hardware redundancy in the device can guarantee high reliability.

It also further developes the traditional redundancy technology and finally sets up the general reliability model under the different failure modes.

Typical application of redundancy technology in substation automation system;

Based on the quality control theory and focused on the efficacy,the reliability analysis systems,such as the bath-box curve analysis,redundancy technology analysis and analysis of ineffectiveness rate of the maintenance and non-maintenance items,are introduced into the medical equipment management in the hospital to improve the reliability of the medical equipment,as wel.

The redundancy technology,error tolerance technology,instruction redundancy,software digital filter were discussed in order to resolve problems of computer software interference suppression.
