Embodiment

[0020] The invention provides a solution to the problem that the power supply cannot be effectively supervised when the peripheral equipment in the fire protection system supplies power independently. The present invention does not need to change the original communication signal transmission channel of the fire bus, and can realize the management of the external control power supply only through the following design.

[0021] Such as figure 1 As shown, the present invention includes a transparent transmission module, a bus interface circuit, an MCU, a control module, a power supply module, a voltage and current detection module and a battery module. Wherein, the bus interface circuit is connected to the fire bus and is connected bidirectionally with the MCU at the same time. Drive signal command. As for the control module, its input end is connected to the output end of the MCU, and the output end is connected to the input end of the power supply module for processing the d...

Abstract

The invention discloses a self-check power supply device hung to a fire fighting bus, which is mainly used to solve the problem that an external control power supply cannot be supervised in the prior art. The self-check power supply device comprises a transparent transmission module, a bus interface circuit, an MCU, a control module, a power supply module, a voltage and current detection module, and a battery module. The transparent transmission module is hung to a fire fighting bus, and connected with the power supply module. The bus interface circuit is connected with the fire fighting bus and the MCU. The MCU is connected with the control module. The control module is connected with the power supply module. The voltage and current detection module is connected with the power supply module and the MCU. The battery module is connected with the power supply module. Through the scheme, the self-check power supply device has such advantages as reliable power supply, real-time monitoring, lower patrol workload and good expansion performance, and has very high practical value and promotion value in the technical field of fire fighting.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a self-checking power supply device connected to a fire protection bus. Background technique [0002] In the fire protection system, peripheral equipment usually needs to be connected to an additional 24V power line to start. If it is necessary to link larger power equipment (such as fire doors, fire shutter doors, fire pumps, etc.), it is necessary to use an external control power supply to provide electrical energy. start, and this external control power supply is an independent device and does not participate in the management of the fire alarm system. [0003] In the event of a fire or external mains failure, the external control power supply will automatically cut off the power supply. If the external control power supply is cut off before the action of the peripheral equipment, then the peripheral equipment will not work normally due to the disappearance of the powe...
