Embodiment Construction

[0034] The core of the present invention is to solve the problem of possible damaged contacts in the MEMS matrix hot switching process. The specific method is to first cut off the current connected to the MEMS matrix when the switching operation is completed. At this time, the current connected to the MEMS matrix is ​​turned on again, so as to avoid the occurrence of the "sticking" phenomenon.

[0035] The present invention firstly provides a method for controlling the switching of matrix lines of MEMS, such as figure 2 As shown, it specifically includes the following steps:

[0036] Step 21: Determine that the MEMS matrix needs to switch the switching unit;

[0037] Step 22: cut off the current connected to the MEMS matrix;

[0038] When it is determined that the switch unit needs to be switched in the MEMS matrix, the access current on both sides of the MEMS matrix needs to be cut off;

[0039] Step 23: The MEMS matrix performs switch unit switching operations to realize...

Abstract

The present invention provides a method and a device for line-switching in an automated main distribution frame (AMDF). It is an object of the present invention to solve the problem of contact point damage which may occur during hot switching of micro electro-mechanical system (MEMS) matrix, and further solve the corresponding problems which may occur during the line-switching in AMDF. In particular, the present invention is preferably embodied in the following way: when switching operation of a switch unit in MEMS is to be performed, the current introduced into MEMS matrix is firstly cut off, and is then recovered when the switching operation is finished, so as to prevent the "agglutinate" phenomena. Therefore, the present invention provides corresponding protection for the switching process of MEMS matrix relays in AMDF, and effectively prevents the "agglutinate" phenomena when the switch unit in MEMS matrix performs switching operation, whereby the reliability of AMDF is enhanced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for switching lines of an intelligent distribution frame. Background technique [0002] In the realization process of AMDF (Intelligent Distribution Frame), some cross matrixes in the system are realized by using MEMS (Micro Electro Mechanical System Matrix) technology. That is to use MEMS technology to realize the matrix of relays and complete the switching of the wiring lines of the intelligent distribution frame. [0003] ADMF with MEMS such as figure 1 As shown, the intelligent distribution frame mainly includes a MEMS matrix, equipment cables and user cables, wherein the MEMS matrix is ​​respectively connected to the equipment cables and the user cables, and the equipment cables are used to connect with equipment in the communication network. The user cable is used to connect with the terminal user in the communication network, and the MEMS matrix c...
