一、概 述 声纳发射系统和其它电子设备一样,在设计系统功能时,应完成可靠性设计,保证系统在规定的环境条件和时间内成完规定的功能。 发射系统的不可靠性给整机带来的后果往往十分严重。因此,在进行可靠性设计时,还应该充分考虑其工作特点,例如机内热损耗造成的温升,强信号对弱信号电路的电磁干扰,负载阻抗的大范围变化,以便设置可靠的检测和保护电路以及进行必要的整机老炼试验等等。 系统可靠性设计应与功能设计和指标实现结合进行,产品的研制过程也就是可靠性设计和实现的全过程。
First, an overview Sonar launch system and other electronic devices, in the design of system functions, the reliability design should be completed to ensure that the system under the specified environmental conditions and time to complete the required functions. Unreliability of the launch system to the machine often have very serious consequences. Therefore, in the reliability design, should also give full consideration to its operating characteristics, such as heat loss caused by the machine, strong signal weak signal circuit electromagnetic interference, a wide range of load impedance changes in order to set up a reliable detection and protection Circuit as well as the necessary machine aging test and so on. System reliability design should be combined with functional design and indicators to achieve, the product development process is the reliability of the design and implementation of the entire process.
