IP self-correction test system

Abstract

The invention provides an IP self-correction test system, which comprises a trolley mechanism fixed on a trolley positioning frame, an RFID card which is fixed on the trolley positioning frame and isinternally provided with a first IP address for fixing a physical position, a card reading module which is fixed on the trolley mechanism and is used for reading and sending the first IP address in the RFID card, a test host which is installed in the trolley mechanism, compares the received first IP address with a second IP address in the test host and modifies the second IP address into the firstIP address if not, a test shielding box which is installed on the trolley mechanism and is internally provided with a to-be-tested product for shielding test interference signals, and a test instrument which is arranged on the trolley mechanism and is used for testing the product to be tested after the test host completes IP address self-inspection and self-correction. According to the IP self-correction test system, the IP address in the test host is self-checked and self-corrected, and the accuracy and uniqueness of the IP address in the test host are ensured.

Description

technical field [0001] The invention relates to the technical field of semiconductor testing, in particular to an IP self-correcting testing system. Background technique [0002] With the increase of labor costs, the development of automation technology in the field of semiconductor electronics technology is expanding rapidly. In the testing section of electronic products, a robotic arm is often used instead of manual feeding for multiple devices, and information is exchanged with the test devices through serial ports or network ports. [0003] If the information is exchanged with the test equipment through the serial port, and the wiring is correct, the one-to-one correspondence between the industrial computer and the test equipment can be guaranteed. [0004] However, the network port relies on the internal IP address of the test PC host for handshake, and it is easy to make mistakes by manually setting the IP address, especially when one display screen is connected to mu...

Problems solved by technology

[0004] However, the network port relies on the internal IP address of the test PC host for handshake, and it is easy to make mistakes by manually setting the IP address, especially when one display screen is connected to multiple PCs, it is more likely to make mistakes by manually setting the IP address; and artificial changes cannot be avoided IP address, so it is impossible to guarantee the one-to-one correspondence between the industrial computer and the test equipment
