For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention。
Embodiment one
The present embodiment provides a kind of method of test, and the executive agent of the method for this test is the device of test。The device of this test can be integrated in dispatch server, and this dispatch server includes matrix optical switch and controls the computer of this matrix optical switch。This matrix optical switch be used for control instrument and ATE(AutomaticTestEquipment, ATE) between connection, it is achieved instrument share, namely this matrix optical switch can control the connection between multiple stage instrument and multiple stage ATE。
As it is shown in figure 1, be the schematic flow sheet of the method for the test according to the present embodiment。The method of this test includes:
Step 101, receives the ATE application sent request。
Wherein, application request is used for applying for Instrument use。Information between ATE and the device of test can pass through communication network alternately, for instance it is mutual that Ethernet carries out information, does not limit in the present embodiment。
Step 102, obtains the information of idle instrument, and sets up the connection between ATE and instrument。
The idle instrument of the present embodiment refers to not currently used instrument, is not namely currently connected the instrument carrying out testing with ATE。The device of test specifically can know which instrument is in idle condition by detecting the duty of each instrument in real time, the instruction reporting duty can also be sent to each instrument, know which instrument is in idle condition according to each instrument feedack, it is, of course, also possible to obtain which instrument current be in idle condition by recording the history duty of each instrument。How the device of concrete test obtains the information of the instrument of free time, does not limit in the present embodiment。
