FCT test system with one computer controlling multiple test stations and control method

Abstract

The invention discloses an FCT test system with multiple test stations controlled by one computer. The FCT test system comprises the computer, n test stations, a communication gathering and distributing device, a router, a code scanning station, a circuit board motion control device and an OK / NG board receiver. The control method of the FCT test system comprises the following steps: S1, detecting a to-be-tested circuit board; s2, issuing a code scanning instruction; s3, uploading a code scanning instruction; s4, judging whether code scanning succeeds or not; s5, transmitting the circuit board and preparing for testing; s6, judging whether the program is downloaded or not; s7, judging whether the program is successfully downloaded or not; s8, testing the circuit board; and S9, receiving the qualified circuit board. According to the testing system and method, multiple computers do not need to be operated at the same time, only one computer needs to be operated, only one upper computer program runs on one computer, the system design is simplified, the hardware cost is reduced, meanwhile, the operation process is simplified, and the error probability of operators is reduced.

Description

technical field [0001] The present invention relates to a FCT test system and a control method, more specifically, to an FCT test system and a control method in which one computer controls multiple test stations. Background technique [0002] The FCT functional test equipment is to provide a simulated excitation operating environment for the circuit board to be tested according to the conditions required for its operation, so that the circuit board to be tested can run in various design working states, including normal working state and fault protection working state. Various parameters in the running state are used to judge whether its function is good or bad. [0003] The degree of automation of production and manufacturing in the country is getting higher and higher, and the penetration rate of machines is getting higher and higher, which has led to the gradual development of FCT functional test equipment from manual operation, semi-automatic operation to fully automatic ...

Problems solved by technology

[0004] However, the existing multi-test station FCT function test system is composed of multiple computers, each test station needs a computer, and each computer needs to communicate with the test station and the motion control system to jointly complete the multi-test station FCT function test For the operation of the system, it is necessary to open each computer one by one and then open the corresponding upper computer software and set the corresponding operating parameters, which obviously increases the complexity of the system and the complexity of the operator. If there are too many, it is easier to make mistakes in operation, there are hidden dangers in quality and safety, and it is not convenient for unified management
