Abstract

The invention relates to the technical field of signal control and provides a signal collecting and driving testing device. The testing device comprises a control terminal, a signal collecting card, a signal driving card, a relay collecting late, a relay driving plate and a guide rail type AC-DC (Alternating Current-Direct Current) power source. In the technical scheme of the invention, a relay dry node manner is adopted for ensuring the polarity of a switching value signal between tested equipment and testing equipment and / or power not to be limited by an opposite side; a relay input-output manner is adopted for realizing the electrical isolation between the tested equipment the testing equipment; in addition, by using a filter circuit, the microsecond-level signal collection is realized and is not affected by a microsecond-level pulse interference signal; and finally the amount of collecting and driving switching value signals of the signal collecting and driving testing device can be freely adjusted and configured; and the signal collecting and driving testing device can simulate gravity type relay equipment of a railway system and is small in volume and flexible to realize.

Description

technical field [0001] The invention relates to the technical field of signal control, in particular to a test device for signal collection and driving. Background technique [0002] In the field of signal control, especially in large-scale control systems involving rail transit, etc., due to the large number of switches used in the signal equipment control system used in engineering projects to collect and drive, it is often necessary to integrate equipment from different manufacturers to complete the system. requirements of the entire system. At present, the most common collection and drive interface is to use relays and other components designed as dry nodes to collect and drive signal switching values. This design method can effectively isolate the power systems of different devices from each other, so that signal collection and The drive will not be affected by the abnormal voltage interference signal of the public power supply or the ground terminal, and it is a safe ...
