1 Current situation of computer room monitoring network system 1.1 System overview The current stage of the seismic data processing center is the Z×M10 ZTE monitoring system. The system is mainly for the operation status of the equipment room, the indicators of the equipment room environment (unrealized), and safety. Real-time monitoring of firefighting and video images and recording of historical data, realizing remote management, remote signaling, remote control, and remote adjustment of the equipment room (unrealized), providing powerful guarantees for the efficient management and operation of the equipment room.
The devices detected by the Z×M10 surveillance system can be classified into two types: smart devices and non-smart devices. The monitoring of non-intelligent devices using the transmitter to detect is to convert the power and non-electricity of the device into a standard signal and access each acquisition module. The monitoring smart device is based on the internal acquisition circuit and communication port of the machine and obtains the data through the communication protocol provided by the manufacturer. No additional sensors and transmitters are required.
1.2 System Components The system is divided into functional categories: front-end signal acquisition, signal transmission, background control, and corresponding software components to form front-end signal acquisition and processing: Set up cameras in the computer room to observe the status of the equipment room and equipment operation status. According to the need to install temperature and humidity detectors, voltage and current detectors, smoke detectors, infrared alarm detectors and other acquisition equipment.
Signal transmission: Z×M×10 system supports wide-area networks such as DDN, X25, and ISDX for long-distance networking, and uses 2M E1 lines for communication, which can simultaneously transmit languages ​​and images.
Background control: Configure one (or several) monitoring servers in the monitoring center, through the monitoring center software, through the acquisition module, manage all front-end cameras, video servers, environmental power monitoring, alarm equipment, access control, etc.
The monitoring center software mainly includes service desk software, reporting station software, node communication software, and database storage programs.
1.3 Functional features of the system 1.3.1 Networking mode The system supports three levels of networking, in the three-level networking, station (SU) and secondary monitoring center (SC), two monitoring centers and three levels The same transmission method is not required between monitoring centers (SCs).
1.3.2 Modular design The system uses a modular design. The main modules are communication module, data management module, protocol processing module, alarm processing module, image control module, information processing module, and intelligent analysis module. Thanks to the modular design and configuration design, the service station can be set to an alarm station, a report station, an image station, etc., as required.
1.3.3 Powerful alarms and information processing The system's alarm levels are classified into three levels: emergency alarms, important alarms, and general alarms. The alarm can be set to be delayed by the user's request. The alarm information is transmitted in real time as the highest priority data in the monitoring network. All alarms in the system can be set by the user. The system automatically generates an alarm report and pops up an alarm screen. The alarm information can be automatically transmitted to the monitoring center. The operator can scroll through the prompt window to view the alarm information and can view the system providing, alarm system table, alarm classification system table, and other historical or print curves. Reports, etc.
1.3.4 Security Management The system supports three levels of management authority, super users, managers, and on-duty personnel. Confirm the restricted operation authority by password to maintain system security. The monitoring center has alarm records and equipment operation records that can be stored in the computer for more than one year, ready for inspection, statistics, etc. at any time.

And real-time monitoring of various UPS power supply voltage, current, frequency, power and other parameters.
2.1.2 Improve the temperature and humidity monitoring of the equipment room The temperature and humidity sensors need to be set in the equipment room. Through the network, the temperature and humidity conditions can be relaxed. When the temperature and humidity exceed the limits, a warning can be issued.
2.1.3 Improve the power supply parameter monitoring function By installing smart power meters on the line cabinets and outlet cabinets, the operating status data is transmitted to the computer system for real-time monitoring purposes.
2.2 There is no effective centralized monitoring and monitoring system of the pre-processing center, which is only partially monitored and has not been effectively monitored by computers. To improve the centralized monitoring function, a monitoring server must be configured in the monitoring center, and an intelligent monitoring data collection machine should be installed as required. Each data acquisition module can be managed in a network transmission or browser mode to manage all monitoring devices and appear in the equipment room. In exceptional circumstances, the travel center may issue or send an alert.
