Taking a semiconductor integrated device as an example, the work failure rate lambda is calculated p1 ：
λ p1 ＝π Q [C 1 π T π V +(C 2 +C 3 )π E ]π L
Looking up the handbook can get the environmental coefficient pi E =6.3; mass coefficient pi Q =1.0; maturation coefficient pi L =3.0; coefficient of temperature stress pi T =0.37; coefficient of voltage stress pi V =1; circuit complexity failure rate C 1 ＝1.4×10 -6 h、C 2 ＝0.0749×10 -6 H; package complexity failure rate C 3 ＝6.0923×10 -6 h。
Therefore, the work failure rate of the diode, the triode and the semiconductor integrated device (44) is determined as follows: lambda p1 ＝0.023428×10 -6 /h；
Finally, the total work failure rate of the whole communication adapter is calculated
The mean time between failure thus obtained was MTBF =984h.
The following can be obtained through the theoretical analysis of reliability: the mean time between failures of the communication adapter of the present invention can reach 600 hours.
(2) Maintainability and testability analysis
The communication adapter is designed by adopting a functional module, mainly comprises a power module, a microphone amplifier of a telephone station, an earphone amplifier, a microphone amplifier for front-back conversation, an earphone amplifier and other functional modules, and is convenient for fault isolation; in the structural design, the accessibility of maintenance is ensured, the disassembly and the replacement are convenient, the regulation is met, and the replacement unit module can adopt a quick plug installation mode so as to be convenient to overhaul, disassemble and assemble; the MTTR is less than or equal to 0.5h by practice test.
The communication adapter is low in complexity, has more external interfaces (mainly including an earphone microphone set, a power supply switching interface, a charging interface and the like), is relatively simple to connect with other equipment (a data transmission interface and a power supply interface of a telephone station), does not need a special maintenance tool, and can position and overhaul most replaceable units by using an auxiliary multimeter and the like.
(3) Security analysis
In order to ensure the test safety, the communication adapter uses the safety voltage with the power supply of DC 26V, and the power supply module has the functions of overcurrent, short circuit and overheat protection, and can ensure the safety of the tested product.
(4) Environmental suitability analysis
Environmental compatibility, which refers to the ability of a device to perform all of its intended functions, performance, and indestructibility under the various environments that the device may be expected to encounter during its life, is one of the important quality characteristics of a device. The communication adapters are installed in the cockpit and rear bay (ZK bay, FK bay) and cannot be operated for a long time or stored under high-temperature and low-temperature environmental conditions. After the product is finished, a low-temperature storage test (24 h), a high-temperature storage test (48 h), a low-temperature working test (2 h) and a high-temperature working test (2 h) are carried out on the product according to the communication adapter and communication instrument environment test outline, and the equipment can normally work after the tests are carried out.
