1. UPS power supply (including DC power supply)

Both the UPS power supply and the DC power supply are equipped with batteries, which guarantees the computer to improve the quality of the power supply and provide continuous power supply after power failure. Through the communication protocol and intelligent communication interface provided by the UPS manufacturer, the UPS is monitored, and the operating status of the internal rectifier, inverter, battery, bypass, load and other components of the UPS is monitored in real time. Once a component fails, the system Will automatically alarm.

The monitoring of UPS in the computer room environment adopts the mode of monitoring only and uncontrolling, to avoid the risk of power outage caused by errors in the monitoring system.

2. Battery

In a UPS uninterruptible power supply system, it can be said that the battery is the pillar of this system, and it is very important to maintain the normal operation of the load equipment by conducting a round-trip detection of the battery pack in time and reliably. To this end, it is necessary to monitor the UPS battery through online battery monitors, DC current sensors and other equipment.

3. Air-conditioning equipment

One of the characteristics of the equipment room is that the equipment is dense and generates a lot of heat. Therefore, air conditioning plays a decisive role in controlling the temperature and humidity of the computer room. Through real-time monitoring, you can fully diagnose the operating status of the air conditioner, monitor the operating status and parameters of the air conditioner components (such as compressor, fan, heater, humidifier, dehumidifier, filter, etc.), and remotely modify the air conditioner through the management software Set parameters (temperature, humidity, temperature upper and lower limits, humidity upper and lower limits, etc.), and restart the precision air conditioner . Even if there is a slight failure of the air conditioning unit, it can be detected by the system and timely measures are taken to prevent further damage to the air conditioning unit.

4. Leakage detection

　There are two types of leak detection systems: positioning and non-positioning. The so-called positioning type refers to a leak detection system that can accurately report specific leak locations. On the contrary, if the system is not located, only water leakage can be reported, but the location cannot be indicated. The system consists of sensors and controllers. The controller monitors the state of the sensor and immediately uploads the information to the monitoring PC when the water condition is found. There are two types of leak detection sensors: wired detection and surface detection. Wire detection is mainly used in the computer room. The line detection uses a leak detection rope to surround the water-affected area. After the leak occurs, the water will contact the detection line to issue an alarm.

5. Power distribution system

The monitoring of the power distribution system mainly monitors the operation status of the power distribution cabinet. It mainly monitors the three-phase phase voltage, phase current, line voltage, line current, active power, reactive power, frequency, power factor and other parameters of the power distribution system and power distribution. Monitor the status of the switch. When some important parameters exceed the danger limit, an alarm will be given.

6. Generator

Monitoring via serial communication requires a serial communication protocol for the generator.

7. Computer room temperature and humidity

At each important position in the equipment room, a temperature and humidity detection module needs to be installed to record the temperature and humidity curve for management personnel to query. Once the temperature and humidity are out of range, the alarm is immediately activated to remind the management personnel to adjust the air conditioner working setting value or adjust the equipment distribution in the equipment room in time, which may make the overall temperature and humidity of the equipment room tend to be reasonable and ensure the safe and stable operation of the equipment room.

8. Monitoring of fresh air system and exhaust system.

Monitor the operation status of the fan, and give an alarm when the fan fails.

9. Lightning protection system

　Real-time monitoring of the working status of the lightning protection module is realized through the switch acquisition module, usually only two monitoring states are on and off.

10. Fire protection system

The monitoring of the fire protection system is mainly the collection of fire alarm signals and gas spray signals, and does not control the fire protection system.

11. Video surveillance

     The digital video monitoring system adopts MPEG4 video compression method, which integrates multi-screen measurement, video playback, video remote transmission, trigger alarm, PTZ control, and device linkage. In the video system components, the video real-time window, video playback window, remote The acceptance window and the dome camera (PTZ) control window are seamlessly embedded as controls to meet different personalized needs.

　　The video system can also be linked with other input signals. Once the video is alarmed, it can also be linked with other devices such as dual-probe probes, door sensors or the "mobile alarm" function supported by its own device to record and output the corresponding control signal.

12. Access control monitoring

   Install an access control system at an important location in the computer room area to effectively monitor and manage the access personnel. For security reasons, the access control system is designed with a separate control and card reading structure.

　　The access control system is composed of a controller, an inductive card reader, an electric control lock and a door opening button (networked system plus communication converter). The card reading method belongs to the non-contact card reading method.

13. Network equipment and application system monitoring

　The host of the monitoring system establishes communication contact with routers, servers, minicomputers, etc. through the network, and directly obtains various information from these network devices. The communication process adopts the international simple network management protocol (SNMP).

　There are currently 4 commonly used network structures in the computer room environment power monitoring communication network: serial port and 485 bus, field bus, Ethernet, and hybrid networking.
