Description
Technical field
The present invention relates to field tests, particularly relate to a kind of radio station Temperature pre-treatment test conversion equipment and method of work thereof.
Background technology
The main composition of airborne ultra-short wave broadcasting station system has following three kinds of situations:
1) be made up of transceiver and control box, ratio is 1:1.
2) be made up of transceiver, control box and boxcar, ratio is 1:1:1.
3) be made up of transceiver, control box and boxcar, ratio is 2:2:1.
In batch production process in radio station, absolutely Temperature pre-treatment test to be carried out to all products, to reject early failure, thus improve product reliability.Criticize production in the radio station of reality, product reprocesses and product is lengthened the life in process, can face following situation:
1) independence is poor.The product that the object tested is not necessarily complete may be often independent transceiver or independent control box.Like this, in order to coordinate the test of transceiver or control box, just needing control box or the transceiver of extra production respective numbers, this not only adds production cost, and delayed the production cycle.
2) layout is too fat to move.For radio station, be generally ten temperature cycles at the check requirements of Temperature pre-treatment test link, the time of each circulation is 8.5h, so total time is 85h.According to the volume difference in radio station self, maximum packing number is generally 12 covers to 25 and overlaps.If packing number increases a set of, test duration at least saves 85h, also saves the test chamber operating cost of 85h simultaneously.Therefore, if maximum packing number can not be utilized well, very large cost waste and cycle delay will be caused.
3) testing efficiency is low.Twice test, in each Temperature pre-treatment test cycle process, is at least carried out in radio station.And according to the requirement of trial curve, the testing time is relatively-stationary, and therefore, test job must complete at the appointed time.Reach this target, except tester oneself improves test speed and correctness, also will reduce the time that tester consumes in wiring switching as much as possible, to improve testing efficiency.
In sum, the Temperature pre-treatment test link in radio station, with actual production demand for guiding, there are three point defects in existing connection plan: independence is poor, and layout is too fat to move and testing efficiency is low.
The consequence that this three point defect causes is then that production cost increases considerably, and the production cycle is seriously delayed.When the main composition of radio station system become above the second or the third situation time, these problems can be more outstanding.
