Measurement and control five-prevention function detection device and system

Abstract

The embodiment of the invention discloses a measurement and control five-prevention function detection device and system. The measurement and control five-prevention function detection device comprises a control module, a five-prevention logic module and an output module; and the control module is connected with the five-prevention logic module, the control module is connected with the output module, the control module controls the output module to output voltage according to five-prevention logic input by the five-prevention logic module, the output voltage is used for providing five-prevention detection signals for equipment to be detected, and the equipment to be detected determines whether the five-prevention function is normal or not according to the five-prevention detection signals. According to the scheme, the required five-prevention logic control output module is called from the five-prevention logic module through the control module to output the voltage serving as the five-prevention detection signal to the to-be-detected equipment, so that whether the five-prevention function of the to-be-detected equipment is normal or not can be quickly determined, and the detection efficiency of the five-prevention function of the to-be-detected equipment is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of anti-misoperation technical field of substation power monitoring system, and in particular to a measurement and control five-defense function detection device and system. Background technique [0002] The substation five-defense system usually consists of three parts - five defenses at the station control layer, five defenses at the bay layer and five defenses at the electrical level. For the newly built or remodeled measurement and control devices in the substation, the automation system technicians configure the anti-misoperation function according to the given five-prevention locking rules. Before the measurement and control device is put into operation, it is necessary to conduct an on-site inspection and acceptance of the locking function of the measurement and control device to determine the correctness of the five-proof locking function of the measurement and control device after the si...

Problems solved by technology

Among them, method 1 requires more steps and is inefficient. At present, method 2 is often used for on-site acceptance, but method 2 requires repeated untwisting and short-circuiting of the terminal strips, which is still not efficient, and there are mistakes. , the risk of affecting other signal circuits of the panel cabinet
