A multi-wire circuit module isolated from each other

Abstract

The invention relates to the technical field of fire control circuits, and concretely relates to mutually-isolated multi-wire circuit modules, which overcomes the problem that conventional multi-wire modules interfere with each other and helps to ensure that a system functions normally. Each mutually-isolated multi-wire circuit module includes a system control circuit module, a state acquisition circuit module, an external interface circuit module and a power supply module, wherein the system control circuit module and the state acquisition circuit module are connected and communicate with each other through an isolation communication circuit module, the system control circuit module is connected to a hand-operated starting circuit module, the hand-operated starting circuit module is connected to a multipath control starting circuit module, the multipath control starting circuit module and the state acquisition circuit module are both connected to the external interface circuit module, the system control circuit module is connected to the external interface circuit module through an alarm controller communication circuit module, and the power supply module is connected to the external interface circuit module.

Description

technical field [0001] The invention relates to the technical field of fire control circuits, in particular to a mutually isolated multi-line circuit module. Background technique [0002] In general industrial and civil construction, the fire alarm control system must be installed to ensure the alarm function when a fire occurs. The multi-line module is used for monitoring and manual control. The multi-line linkage point (relay module) can be controlled through multi-line The buttons on the linkage panel can be operated manually, or an automatic program can be programmed on the alarm host for automatic control. Even if the multi-line module is in the state of the fire alarm controller crash or the control system is paralyzed, the multi-line module can still start or close the corresponding multi-line linkage point through manual control. The multi-line module monitors each multi-line linkage point in real time, and then The situation of each multi-line linkage point is tran...

Problems solved by technology

The data acquisition module is powered centrally, and the external interface control line is inevitably poorly insulated or short-circuited, etc. Since the multi-line module and other modules of the system are powered centrally, as long as there is a multi-line module with poor insulation or short-circuit of the external line, etc. may cause the system to malfunction
