Embodiment Construction

[0014] In order to make the objectives, technical solutions and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0015] see figure 1 , the digital quantity board card IO channel signal testing system in the real-time digital simulation system provided by the present invention includes: two 32-bit switch elements, RTDS digital quantity board card, indicator light element and two shift modules. The RTDS digital boards include GTDO (digital output) boards and GTDI (digital input) boards, and the GTDO (digital output) boards and GTDI (digital input) boards each have 64 IOs. mouth. The output of the 32-bit switching element is equally divided into two channels, of which 16 channels are directly connected to the 16 IOs of the GTDO (digital output) board in a one-to-one correspondence, and the other 16 channels are connected to a shift module. After th...

Abstract

The invention discloses an IO channel signal test system of a digital quantity board card in a real-time digital simulation system. The system comprises two 32-bit switch elements, two shifting modules, an RTDS digital quantity board card and indicator lamp elements. The RTDS digital quantity board card comprises a digital quantity output board card and a digital quantity input board card, wherein 16 circuits of the 32-bit switch elements are connected with 16 IOs of the digital quantity output board card in a one-to- one correspondence manner, and the other 16 circuits which are connected with a shifting module are connected with 16 IOs of the digital quantity output board card in a one-to- one correspondence manner. The digital quantity output board card is connected with the input port of the digital quantity input board card. Each IO port of the digital quantity input board card is connected with an indicator lamp element. The IO channel signal test system is in no need of other external oscillography apparatuses (wave recorder or signal generator), is reliable in realization method, and is simple and quick in operation.

Description

technical field [0001] The invention relates to a digital board card IO channel signal testing system in a real-time digital simulation system. Background technique [0002] Before the RTDS (Real Time Digital Simulator, real-time digital simulator) simulation test, it is necessary to check the availability of the RTDS digital board and whether its IO channel can transmit data correctly; during the RTDS simulation test, the digital IO signal The channel often fails, and the correct data transmission cannot be realized. At this time, it is necessary to check the IO channel of the RTDS digital board, and determine whether the RTDS digital board is faulty through testing, and then eliminate the fault to ensure the smooth development of the RTDS simulation test. RTDS digital board (GTDO (digital output) board and GTDI (digital input) board) IO channel test is an extremely important test link in the power system RTDS modeling simulation test, and it is the correct result of the po...
