Smoke detection unit, smoke detection system and smoke detection device

摘要

The invention relates to a smoke detection unit (10) with a housing, especially used on ships to detect smoke in sample gas. The unit comprises a smoke detection device integrated in the housing, at least an inlet for the sample gas, devices (5,7) connected with an aspirator (6) used for the sample gas, and/or the aspirator for the sample gas, and a signal output end (2). The smoke detection unit is simple in installation, small in space occupation, and can be preferably integrated in a shipborne monitoring system. The smoke detection unit has an additional singal connection device, used to electrically connect with at least a detection device arranged in a remote manner and preferably electrically connect with data lines of other smoke detection devices, and at least a communication and analysis unit used to communicate with the remote detection device through a signal connection device, or the smoke detection device is provided with a dust filter and/or a sample room is provided with a device used for air flow monitoring.
