Stored program control exchange user board maintenance and detection device

Abstract

The invention discloses a stored program control exchange user board maintenance and detection device. The stored program control exchange user board maintenance and detection device comprises a central control unit, a signal generation and output unit, a signal compare and detection unit, a display unit, a test synchronously auxiliary unit, a test signal jumping connection unit, a test interface unit, a test probe, a signal acquisition and processing unit and a power source unit. The stored program control exchange user board maintenance and detection device aims at the problem that a large quantity of stored program control exchange user boards in the current market cannot be repaired on site in short time or cannot test after being repaired when being damaged, creatively combines the signal source technology, the computer control technology, the signal acquisition technology and the signal detection and processing technology, achieves on-site maintenance and detection of the stored program control exchange user boards, solves the problem that maintenance through the stored program control exchange user board technical support mechanisms is difficult and reduces maintenance costs.

Description

technical field [0001] The invention belongs to the field of equipment testing, in particular to a testing device for user circuit boards. Background technique [0002] The program-controlled switchboard is the core equipment of telephone communication, the market usage is huge, and the number of damaged switchboard user boards is also very large. At present, after the user board of the switch is damaged, it is mainly returned to the manufacturer for repair, resulting in high cost. Personnel with certain maintenance experience in technical repair institutions can basically perform component-level maintenance. However, since all the equipment sent for repair is single-board equipment, it is difficult for technical repair institutions to have various program-controlled switches that meet the needs for use as test platforms, resulting in The fault described by the repair party is so difficult to recover that it cannot be repaired; or the user board that has an accurate grasp...

Personnel with certain maintenance experience in technical repair institutions can basically perform component-level maintenance. However, since all the equipment sent for repair is single-board equipment, it is difficult for technical repair institutions to have various program-controlled switches that meet the needs for use as test platforms, resulting in The fault described by the repair party is difficult to recover, so that it cannot be repaired; or the user board has an accurate grasp of the fault, and it is difficult to perform system testing after repair
