1.2 air-conditioning equipment monitoring

The engine adopts precision air-conditioner, the user may act according to the precision air conditioning supplier communication protocols, real-time monitoring of precision air conditioning of air temperature, humidity, cooling water temperature and flow in and out and refrigeration, cooling water pumps operating current parameters; monitoring status including compressor status, fan status, heater, dehumidification device status (water-cooled air-conditioning can also be monitored to the cooling towers of the pond surface State, cooling tower fan status, cooling water valve status, etc.) and other working conditions; displays and records the various parameters of the curve, and a variety of alarm status in real time recording and alarm processing. Control air conditioning in the start-up and shut-down, adjust the temperature and humidity.

1.3 fire system monitoring

Through the acquisition of fire or smoke detectors, controller of temperature detector of alarm signal real-time monitoring of the fire and police state, when the fire monitoring system with intuitive screen displays the alarm message and alarm notifications, control measures such as the door opened the wind equipment, start-up and other related equipment.

1.4 temperature and humidity monitoring

Through the acquisition of temperature and humidity sensor monitoring of temperature and humidity data, to intuitive screen real-time recording and display room of regional changes in temperature and humidity data and curve, as well as transboundary alarm information processing.

1.5 video surveillance system

Video monitoring system uses the concept of the video configuration, each channel of the image to control the configuration of a random insertion interface, for a large monitoring system, the electronic map way to centrally manage all site data and images of the interface that is very convenient. Due to the dynamic environment monitoring and closed circuit monitoring into one, and therefore can achieve dynamic environment and image of linkage control, once an exception occurs, the control system automatically eject the scene image screen, instant video and repeat alarm and processing.

1.6 leakage monitoring system

For the computer room, water cannot be ignored security one of the main content. Modern rooms housed many precision electronic devices, such as switching, network servers, and provide constant temperature and humidity environment by private air conditioning, and air conditioning operation requires to have the humidification of the water and drainWater and air conditioning of condensed water. Air conditioning of water system on the floor following numerous transmission cable and the power plug and terminal box constitute great harm, even if it is a very small leaks, can also cause computer room equipment operation breakdown, incalculable economic losses. In order to guarantee the room network equipment uptime, installed in the floor of the leakage protection on computer room equipment is very important. The precise location of the leak was found in a timely manner, in a timely manner, to ensure the security of the entire system.

Water leakage monitoring system leak through the acquisition of alarm signal monitoring host any leakage of water leakage sensors, in the event of an alarm, immediately cut off on the water pipes and water mains water solenoid valve on the completely closed water, cut continue to discharge occurs, and you can locate specific leak detection system, at the same time, the alarm message via SMS platform is sent to the relevant managerial personnel, and on site audio and light alarm.
