I. Overview
The computer room environment monitoring system is a computer network that comprehensively utilizes computer network technology, database technology, communication technology, automatic control technology, and new sensor technology. It provides an automation based on computer technology and based on centralized management monitoring mode. Intelligent and high-efficiency technical means, the system monitoring objects are mainly equipment room power and environmental equipment (such as: power distribution, UPS, air conditioning, temperature and humidity, water leakage, smoke, video, access control, fire protection system, etc.)
2. Items and contents of the computer room environment monitoring
1. Power distribution system
Mainly monitor the three-phase phase voltage, phase current, line voltage, line current, active power, reactive power, frequency, power factor and other parameters of the distribution system and the status monitoring of the distribution switch. When some important parameters exceed the danger limit, an alarm will be given.
2. UPS power supply (including DC power supply)
Real-time monitoring of the operation status of UPS internal rectifier, inverter, battery, bypass, load and other components through the communication protocol and intelligent communication interface provided by the UPS manufacturer. Once a component fails, the machine room power environment monitoring system will automatically Call the police. In the system, the monitoring line of UPS adopts the mode of monitoring only and not controlling.
3. Air-conditioning equipment
Through real-time monitoring, it can fully diagnose the operating condition 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 can pass the power room environment monitoring system The management function can remotely modify the air conditioning setting parameters (temperature, humidity, humidity 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 power environment monitoring system of the computer room, and timely measures are taken to prevent further damage to the air conditioning unit.
4. Temperature and humidity of the equipment room
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 working setting of the air conditioner in time or adjust the distribution of equipment in the equipment room
5. Water leak 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. The opposite is true without positioning the system. Only leaks can be reported, but the location cannot be indicated. The system consists of sensors and controllers. The controller monitors the status of the sensor and finds the water condition and immediately uploads the information to the monitoring PC. There are two types of leak detection sensors: wired detection and surface detection. Wire detection is mainly used in the computer room. Line detection uses a leak detection cord. Surround the water-affected area. After the water leakage occurs, the water will contact the detection line to give an alarm.
6. Smoke alarm
The smoke detector has a built-in microcomputer control, fault self-test, can prevent false alarms, output pulse level signals, relay switches or on and off signals. When smoke enters the ionization chamber, it will destroy the balance of the electric field of the smoke detector, and the alarm circuit Alarm is detected when the concentration exceeds the set threshold.
7. Video surveillance
The computer room environment monitoring system integrates video monitoring. The image adopts MPEG4 video compression mode, which integrates multi-screen measurement, video playback, video remote transmission, trigger alarm, PTZ control, and device linkage. The video system can also be combined with other input signals. Under the linkage, once the video alarms, it can be linked with other devices at the same time, such as dual-probe probe and door sensor to record.
8. Access control monitoring
The access control system is composed of a controller, an inductive card reader, an electronically controlled lock, and a door opening button (a networked system plus a communication converter. The card reading method belongs to a non-contact card reading method, and the system effectively monitors and manages the entry and exit personnel.
9. 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.
3. Functions of the computer room environment monitoring system
Monitoring / monitoring function
➤ The traditional computer room management adopts a system of daily inspections, such as checking each morning and evening, and manually recording some core operating parameters of the equipment and archiving them. The data obtained in this way is limited to a certain period of time, the work is monotonous and labor-intensive. The real-time monitoring function of the computer room environment monitoring system can solve this problem.
➤ The system has functions of remote monitoring, telemetry, remote control and remote adjustment, the so-called "four remotes", which centrally monitors and manages the entire system to achieve the goal of fewer people on duty and unattended.
