The computer room power environment monitoring system includes embedded computer room power environment monitoring system, multi serial port server power environment monitoring system, traditional power environment monitoring system, and pre computer room power environment monitoring system. Next, we will compare the advantages and disadvantages of these different types of machine room power environment monitoring systems.

1、 Embedded computer room power environment monitoring system

With the improvement of the system configuration characteristics of embedded systems and the implementation of protocol bottom end interpretation, it is possible to achieve bottom end collection, bottom end protocol interpretation, consistent coding, and active reporting.

The on-site supplementary monitoring equipment is collected and interpreted by the monitoring main equipment at the bottom. The upper part communicates with the monitoring host according to the consistent coding protocol, and adopts the active reporting system to save network bandwidth and reduce Internet data traffic.

Features and benefits: Multi directional monitoring content, simple wiring, and high efficiency in timely data transmission.

2、 Multi serial port server power environment monitoring system

With the improvement and popularization of 1-16 port multi serial port servers, the new dynamic environmental monitoring system replaces the application of computer multi serial port cards, solving the problem of long-distance wiring between the monitored equipment and the monitoring host. The on-site RS232/RS422/RS485 mechanical equipment is connected to the multi serial port server, and the TCP/IP data is transmitted to the monitoring host through the multi serial server. The transmission interval is not limited by wiring and can save wiring. Its implementation function is similar to that of a multi serial port card, which bags the serial port mobile data network and openly transmits it to the monitoring host.

Disadvantages: Adopting an open transmission system, the interpretation of mechanical equipment communication protocols is carried out by the monitoring host. If the network is unstable or the monitoring host detects abnormalities, monitoring will be lacking; Due to multiple socket changes, the risk of mechanical failure has increased; The point-to-point collection system is adopted, and the protocol interpretation is realized by the monitoring host. The Internet data flow is large, and the network bandwidth pressure is too great.

3、 Traditional power environment monitoring system

With the improvement of the computer's ability to solve problems and the popularization of the Internet, the embedded computer (also known as the monitoring host), the driving force of fund allocation, the security monitoring system, adopts the method of multiple serial cards to collect the mechanical equipment at the bottom, and realizes the connection of data transmission and timely statistical data.

The intelligent communication ports (RS232/RS422/RS485) or enhanced collection modules of each mechanical equipment are wired to the industrial control computer (the computer running the driving force security monitoring system collection program) according to the construction project, and the protocol interpretation and data processing methods are implemented by the industrial control computer.

Advantages: The monitoring content is relatively multi-faceted and the structure is clear

Disadvantages: The wiring of construction projects is relatively complex, the wiring cost increases, and it relies on the characteristics of industrial control computers; The interpretation of communication protocols for mechanical equipment is carried out by industrial control computers. If an industrial control computer detects an abnormality (which is ultimately a high failure rate caused by solid-state drives, storage, network servers, power transformers, and viral infections on every computer, 7 * 24 * 365 days of operation), monitoring will be lacking, resulting in temporary blind spots in monitoring. Industrial control computers need to be installed in suitable geographical environments, such as power supply systems, operating temperatures, and sound card racks.

4、 Pre computer room power environment monitoring system

In the early stage, the dynamic environmental monitoring system adopts a single node non network connected security monitoring system. Each node works independently and can only test simple main parameters of the computer room, such as geographical environment temperature and humidity, leakage, smoke detectors, door magnets, working voltage, and important power distribution switches. The vast majority of tests are based on simple total power switch values and small analog input values. The monitoring main device conducts local collection and notifies the responsible person in the data center of the alarm based on the PSTN telephone system or SMS platform SMS.

Advantages: Low monitoring cost, time-saving and labor-saving implementation.

Disadvantages: Simple monitoring content, poor timeliness, inability to provide a comprehensive management model, and lack of statistical data applicability for subsequent analysis.
