The invention discloses an information machine room safety monitoring system based on the things of Internet. The system comprises a power frequency power supply abnormity alarm module used for switching to a standby power supply for supplying power for a cabinet when current abnormality increase of a power frequency power supply network is detected, a main control module, a linear temperature sensing detector module used for monitoring temperature of cables under an antistatic floor in a machine room, an infrared light beam smog sensing fire detector module used for monitoring combustion smog of parallel setups in the machine room, a machine room air conditioner temperature control module used for monitoring internal environment temperature of the machine room to maintain the constant temperature, an air conditioner electricity abnormality alarm module used for carrying out electricity monitoring on a temperature reduction large power air conditioner in the machine room, and a security data acquisition module used for detecting door change of a base station machine room and shooting door conditions. The system is advantaged in that an initial fire stage of the machine room caused by different factors can be timely discovered, protection measures and alarm motions are automatically carried out, automatic environment temperature control of the air conditioner is realized, and the security data can be timely acquired.
