Problems solved by technology

[0002] In general industrial and civil construction, fire alarm devices must be installed to ensure the alarm function when a fire occurs. The fire display panel is used to display the fire situation of the floor or partition. The alarm detector detects the fire signal and sends it to the fire alarm. After the alarm controller and the fire display panel receive the fire signal sent by the fire alarm controller, the fire display panel will display the number of the detector that generated the alarm and related information, and at the same time send out an audible and visual alarm signal to notify the personnel in the fire area and put the fire Losses are reduced to a minimum. The communication between the existing fire display panel and fire alarm controller can only be completed through RS485, which occupies a single circuit, which is not conducive to the use of large-scale systems.

Embodiment Construction

[0015] See figure 1 , figure 2 As shown, a fire display panel control circuit includes a fire alarm controller and a fire display panel. The fire display panel includes a communication interface circuit and a system processing circuit. The system processing circuit is connected to the fire alarm controller through the communication interface circuit. The communication interface The circuit includes interfaces T+ and T- connected to the fire alarm controller. Interface T+ is connected to the anode of diode V10 and cathode of diode V14. Interface T- is connected to the anode of diode V13 and cathode of diode V12. Connect to ground, connect the cathodes of diode V10 and diode V13 to the anode of diode V15, the cathode of diode V7, and the sixth pin of optocoupler U11. The cathode of diode V15 is connected to one end of resistor R17, and the other end of resistor R17 is connected to the set Electrode, one end of resistor R22, one end of capacitor C21, one end of capacitor C22, t...

Abstract

The invention relates to the technical field of fire control circuits, in particular to a fire indication panel control circuit. The mode that a traditional fire indication panel has an independent circuit communication bus and shares one circuit communication bus with a warning detector is changed. The fire indication panel control circuit facilitates use of large systems, comprises a fire warning controller and a fire indication panel, and is characterized in that the inside of the fire indication panel comprises a communication interface circuit and a system processing circuit and the system processing circuit is connected with the fire warning controller through the communication interface circuit.
