Abstract
The utility model discloses a kind of tower signal switching relay matrix arrangement, comprise multiple plate and carry relay matrix, multiple plate carries the upper and lower layering interval of relay matrix and arranges, and the row, column interface relays that every laminate carries relay matrix is all in series with single-pole double-throw (SPDT) connection relay to form row Access Control and row Access Control; First stationary contact of the connection relay that adjacent layer row, column is corresponding is interconnected respectively by web joint interface, and the second stationary contact of the connection relay of every layer is connected with the output interface of this layer respectively; Relay coil one end that composing plate carries relay matrix is connected with stabilized voltage supply, and the other end is connected with the output control interface based on CAN single-chip microcomputer respectively by relay driving chip; The CAN communication interface of carrying relay matrix respectively with every laminate by CAN driver module based on the communication interface of CAN single-chip microcomputer is connected.The utility model is that quick complete pair of panel carries the configuration of relay matrix, distribution.
Description
Technical field
The utility model relates to relay matrix device, especially relates to tower signal switching relay matrix arrangement.
Background technology
The relay matrix signal matrix be often applied in automatic test field switches, circuit Fast transforms.Because control path is consistent with connection mode, be carry out connecting and disconnecting by physical contact, so technical indicator is good and cheap, be thus commonly used in test PCB(printed wiring board), the aspects such as larger current direct fault location are carried out to hardware.But, due to relay matrix wiring board wiring reason, the scale of relay matrix (the row, column number of matrix) is restricted, when needing comparatively multi signal conversion, normal use polylith relay matrix wiring board carries out connection expansion, and the relay matrix connected after expansion can not change its series and parallel relation.Because connected mode is flexible cord or wire jumper, therefore not only waste time and energy, the normal mistake that occurs connects phenomenon, and make a mistake it is very difficult to check when connecting simultaneously.
Summary of the invention
The utility model object is to provide a kind of tower signal switching relay matrix arrangement.
For achieving the above object, the utility model takes following technical proposals:
Tower signal switching relay matrix arrangement described in the utility model, comprise multiple plate and carry relay matrix, described multiple plate carries the upper and lower layering interval of relay matrix and arranges, and the row, column interface relays that every laminate carries relay matrix is all in series with single-pole double-throw (SPDT) connection relay to form row Access Control and row Access Control; First stationary contact of the connection relay that adjacent layer row, column is corresponding is interconnected respectively by web joint interface, and the second stationary contact of the connection relay of every layer is connected with the output interface of this layer respectively; Relay coil one end that composing plate carries relay matrix is connected with stabilized voltage supply, and the other end is connected with the output control interface based on CAN single-chip microcomputer respectively by relay driving chip; Described CAN communication interface of carrying relay matrix respectively with every laminate by CAN driver module based on the communication interface of CAN single-chip microcomputer is connected.
The utility model advantage is to realize configuration, the distribution that complete pair of panel rapidly carries relay matrix, possesses easy cycle tests simultaneously.The annexation of connection relay first stationary contact that adjustment adjacent layer row, column is corresponding, can realize multiple plate easily and carry series and parallel relation between relay matrix; Carried the CAN communication interface of relay matrix by every laminate, reach and automatically identify and return CAN information to host computer, inform the matrix size that host computer configures.
