Tester and test control device and method

A test control device comprising a parallel control unit, a plurality of station control units and a packing unit, wherein each of the station control units corresponds to at least one device under test;

• the parallel control unit is connected with the station control units and a host respectively and is configured to receive test items sent by the host and send each of test sequences in the test items to a station control unit corresponding to a device under test corresponding to the test sequence;
• each of the station control units is connected with a plurality of function boards, wherein functions realized by the function boards are different, and any station control unit of the station control units is configured to send, according to the functions required to realize for received test sequence(s), the received test sequence(s) to corresponding function boards so as to test device(s) under test corresponding to the test received sequence(s), and control the plurality of function boards to stop testing a target device under test when the testing of the target device under test fails, wherein the target device under test is a device under test corresponding to the any station control unit;
• and
• the packing unit is connected between the station control units and the function boards in series and configured to pack test sequences sent by at least two station control units to the same function board and channel numbers corresponding to the test sequences, and send them to function boards corresponding to the channel numbers, wherein channels to which the channel numbers belong are located between the function boards and the devices under test.
