fct automated test system integrated in ict equipment

Abstract

The invention provides an FCT automatic test system integrated in ICT equipment. The ICT equipment includes an industrial computer, an ICT motorized component control unit, an ICT detection unit, and a needle bed. The FCT automatic test system includes an FCT signal detection circuit unit and an ICT / FCT cooperative control The circuit unit and the ICT / FCT strong and weak current isolation circuit unit; the ICT equipment is respectively connected with the ICT / FCT cooperative control circuit unit and the FCT signal detection circuit unit; the ICT equipment and the FCT signal detection circuit unit are respectively isolated from the ICT / FCT strong and weak current The circuit unit is electrically connected, and the needle bed is electrically connected to the ICT / FCT strong and weak current isolation circuit unit; the ICT / FCT strong and weak current isolation circuit unit switches between the needle bed and the ICT detection unit and the needle bed according to the instruction of the ICT / FCT cooperative control circuit unit The connection with the FCT signal detection circuit unit. The FCT automatic test system integrated in ICT equipment of the present invention realizes the integrated test of ICT and FCT, has a high degree of automation, improves test efficiency, greatly reduces the cost of promoting integrated test, and reduces the test labor intensity of testers.

Description

Technical field [0001] The present invention relates to the field of air conditioning testing, in particular to an FCT (Function Circuit Testing) automated test system that can be integrated in an ICT (In Circuit Tester, on-line tester) device. Background technique [0002] At present, controller manufacturers generally have 2 methods for ICT (In Circuit Tester) and FCT (Function Circuit Testing) testing: 1. ICT and FCT split testing; 2. ICT and FCT integrated testing ; The first is the technology commonly used in the industry in the early stage, and the second is the more advanced testing method in the near future, which is also the future trend. In the actual ICT+FCT integrated test system, various ICT / FCT integrated test integrated systems in the industry have a fatal common problem-the cost is very expensive, because it eliminates the original ICT test system of the enterprise and the current Some mechanical parts and outer box structure, this kind of integrated test system ...

AI Technical Summary

Problems solved by technology

In the actual ICT+FCT integrated test system, all kinds of ICT / FCT integrated test integrated systems in the industry have a fatal common problem - the cost is very expensive, because it eliminates the original ICT test system of the enterprise, the existing Some mechanical components and outer box structures, such an integrated testing system, are really costly to promote, and the effective utilization of resources is extremely low, so the benefits brought to the enterprise are extremely limited.

In addition, in the existing ICT / FCT integrated test system, the switch between the ICT weak current test and the FCT strong current test line connection is generally switched by high / low pin switching. Incorrect positioning, thimble bias, thimble bending, thimble not in place, etc. Due to a series of problems of thimble contact, the test is often unstable, and once the strong and weak current thimbles are accidentally contacted, it will cause the danger of burning the test system and the circuit board under test. , which will be fatal damage to the test system

The high cost and high risk of this test system have exposed the problems that need to be solved urgently in this test system
