A micro module data center room channel environment intelligent monitoring system integrates a DC12V sensor working power supply, a smoke alarm sensor, a water logging alarm sensor, an intelligent temperature and humidity transmitter, a door access controller, and a skylight controller. The system can monitor the temperature, humidity, smoke alarm status, water logging alarm status, skylight status and end door status in a cold channel in real time. Local fire alarm linkage and security linkage control is realized. The alarm response speed of a micro module data center is improved. The security risk in a channel is reduced. A main control module adopts an ear-hung installation module of standard 1U specification, and is easy to install. A DI port adopts an RJ-45 interface and a standard 568B port line sequence. Wiring ports are unified. Wiring is simplified, and construction is facilitated. The number of front-end acquisition and control modules of the micro module data center channel monitoring system is reduced. The cost of the micro module data center monitoring equipment is reduced.
