Multi-module communication management method in ATE test system and ATE test system

A multi-module communication management method in an automatic test equipment (ATE) test system, wherein the ATE test system comprises an ATE tester and a tester auxiliary device, wherein the ATE tester comprises:

• a test head and an industrial control computer, and the tester auxiliary device comprises a handler;
• the ATE test system is configured to operate a session management module, at least one test module, and at least one listening module;
• the method is performed by the session management module, wherein the session management module is separately connected to the at least one test module and the at least one listening module, and the method comprises:
• receiving an update instruction sent by a target test module, wherein the update instruction carries identifier information corresponding to the target test module and a shared information identifier corresponding to the target test module, and the target test module is a test module sharing updated shared information when the shared information is updated;
• querying a session table according to the identifier information corresponding to the target test module to obtain a listening module identifier set corresponding to the target test module, wherein the session table is stored in the session management module;
• sending a demand instruction to a listening module corresponding to each listening module identifier in the listening module identifier set, wherein the demand instruction carries the identifier information corresponding to the target test module and the shared information identifier corresponding to the target test module;
• receiving an acquisition instruction sent by the listening module and sending the acquisition instruction to the target test module so that the target test module sends shared information corresponding to the shared information identifier to the session management module, wherein the acquisition instruction carries the identifier information corresponding to the target test module and the shared information identifier corresponding to the target test module;
• and
• receiving, through the test head, the shared information corresponding to the shared information identifier sent by the target test module, and sending the shared information corresponding to the shared information identifier to the listening module so that the listening module generates a replacement instruction according to the updated shared information and controls the handler to replace a tested device under test.
