摘要
BIT技术是当今最重要的在线故障诊断技术之一,已经被广泛应用于航空电子设备中,在航空领域以外的应用虽然还比较少,但也已经起步。随着电子设备维修性要求的提高以及设备本身要求具备检测隔离故障的能力以缩短维修时间,BIT在测试领域研究中将越来越重要。功能电路BIT系统是电子设备整机BIT系统的重要组成部分,因此从解决实际问题出发,对几种典型的功能电路进行BIT策略方案设计,并使用Multisim软件对所设计的BIT监测电路进行仿真,仿真结果表明,所设计的BIT电路是可靠及有效的。
BIT technology is one of the most important means of fault diagnosis online nowadays,which applied widely in aviation electronic equipment but applied rarely in other field.As the electronic equipment maintainability increases as well as equipment itself requires the ability to check the isolated faults in order to reduce maintenance time,BIT research in the testing field will be increasingly important.Function circuit BIT system is an important component of electronic equipment BIT system,and the paper has designed the BIT strategic scheme for several typical function circuits depending on the practical problem solution.The BIT test circuits have simulated by the Multisim software and the results have proven that it is reliable and valid.
