K interface error code testing method and system thereof

Abstract

The invention discloses a K interface error code testing method and a system thereof; the system is composed of an interface unit, a transmitting unit, a receiving unit, a clock unit, a control unit and a human-computer interface; the human-computer interface is connected with the control unit which is respectively connected with the transmitting unit, the clock unit, the receiving unit and the interface unit; the transmitting unit is connected with the interface unit which is respectively connected with the receiving unit and the clock unit; a clock signal is output by the clock unit by parameter setting of the human-computer interface under the control of the control unit, the transmitting unit generates test data which is converted through the interface unit and is output in a driving way, the input tested data is input to the receiving unit to carry out error code counting after being received and converted by the interface unit, finally, the data is processed by the control unit for displaying, so as to carry out K interface error code testing. The invention does not need conversion equipment and can accurately and directly realize K interface error code testing; the method can be used as the standard of the K interface error code testing.

Description

technical field [0001] The invention belongs to the K interface testing technology, in particular to a K interface error code testing method and system thereof. Background technique [0002] The K interface is a single-way wired interface, which is the user terminal interface in the communication network and is widely used. There is no testing instrument for the bit error test of the K interface. At present, an indirect measurement method can be used, that is, using an interface conversion device to convert the K interface into an RS232 interface, and then use a data bit error tester with an RS232 interface for measurement. The interface conversion device is designed for the purpose of long-distance point-to-point communication of the RS232 interface terminal. Therefore, there are great defects in using this test method. First, the equipment used for communication purposes is used as a test, and there are many unsuitable ones. On the one hand, if the system clock of the tes...

Problems solved by technology

The interface conversion device is designed for the purpose of long-distance point-to-point communication of the RS232 interface terminal. Therefore, there are great defects in using this test method. First, the equipment used for communication purposes is used as a test, and there are many unsuitable ones. On the one hand, if the system clock of the test is not the clock of the bit error detector, the function of the test is limited by the function of the conversion device, and the test interface cannot truly reflect the performance of the K port; second, this test method is not standardized and cannot be used as a test standard; The third is that this test is cumbersome and inconvenient to use.
