Title:
A METHOD AND A MEANS FOR SWITCHING CIRCUITS OF MEMS MATRIXES AND OF AN AUTOMATED MAIN DISTRIBUTION FRAME
Document Type and Number:
WIPO Patent Application WO/2006/094463
Kind Code:
A1
Abstract:
A method and a means for switching circuits of MEMS matrixes and of an automated main distribution frame, for resolving the problems, in which the contacts are spoiled, presented during the MEMS (micro-electronics mechanical system) matrix active switch, and further for resolving the corresponding problems presented during the circuit-switched process in the automated main distribution. It is realized as following: when the MEMS matrix needs an operation to switch the switch unit, at first, it breaks the current introduced into the MEMS matrix, and when the switch is finished, it is connected again to introduce the current into the MEMS matrix, so that it can avoid the presence of the “conglutination” phenomenon. Therefore, it can provide the corresponding protections to the switch process of the MEMS matrix relays in the AMDF (automated main distribution frame) and can effectively avoid the presence of the “conglutination” phenomenon when the MEMS matrix proceeds the operation to switch the switch unit, so it improves the reliability of the AMDF.
