Abstract

The embodiment of the invention provides a control detection circuit and a detection method. Fault detection can be carried out on a wiring line of a fire control system. The circuit comprises an auxiliary circuit unit which is communicated with the terminal fire-fighting equipment and is used for protecting the terminal fire-fighting equipment; a control circuit unit which is communicated with the auxiliary circuit unit and is used for receiving an action signal of the central control processor to control the terminal fire-fighting equipment to work, wherein the control circuit unit comprises a control signal acquisition end and a feedback signal acquisition end, and the control signal acquisition end and the feedback signal acquisition end are respectively used for acquiring a control voltage signal and a feedback voltage signal. The method comprises the following steps: judging a circuit connection state according to a control voltage signal and a feedback voltage signal; and when the circuit connection state is normal, receiving the action signal, and judging the working state of the terminal fire-fighting equipment according to the control voltage signal and the feedback voltage signal.

Description

technical field [0001] One or more embodiments of the present application relate to the field of power system and automation technology, and in particular to a control detection circuit and detection method. Background technique [0002] In the fire control system, the fire-fighting equipment is generally controlled through an external active circuit, and the fire-fighting equipment provides a pair of normally open contacts to feedback the action of the equipment. In the external active circuit, the action of the fire-fighting equipment is controlled by the relay, and the action signal of the fire-fighting equipment is collected. The existing external active circuit cannot collect the external wiring connection information when the fire-fighting equipment is not in action, and cannot detect the fault of the external wiring circuit of the fire-fighting equipment in time. When a fire occurs, the fire-fighting equipment cannot act in time, and even the control circuit can contr...
