Centralized monitoring system software functions
The centralized monitoring system generally includes: client software Client, running software S and monitoring hardware. The client software is an important part of the centralized monitoring system. The client software is the user monitoring interface. The monitoring results are reflected to the user through the client software. The user controls or sets the monitoring object through the client software.
The environmental power monitoring system shall have functional modules such as data management, security management, configuration management, alarm management, report management and remote management. The operating systems, database management systems, network communication protocols and programming languages ​​used in computer systems must adopt international standards. General system (and easy to integrate into local network management system). The computer network may be a local area network, a wide area network, transmission media may be Ethernet, FDDI, ATM, ISDN, PSTN, etc., and the transmission protocol is TCP/IP, SNMP, and the like. The client software can detect the remote agent running status and automatically restore the connection.
System main hardware composition and configuration
The entire monitoring system should adopt a tandem structure, which consists of the on-site monitoring center, monitoring unit, monitoring module and remote monitoring station (far-end user). The main hardware equipment of the system refers to each major monitoring host of the monitoring center, all interface conversion equipment, and general-purpose collectors. The system should also be properly configured according to other requirements such as printers, multimedia devices, multi-serial cards, MODEM, UPS, sensors, transmitters and other equipment. Data collection is divided into collection of non-intelligent equipment (temperature and humidity, water leakage, infrared alarm) and intelligent equipment (EPS, UPS, air-conditioner for computer room) and monitoring of distribution cabinets. The collection of non-intelligent devices is divided into analog acquisition and switching acquisition. Temperature and humidity are analog quantities, infrared and leakage are switching quantities.
The monitoring unit and the monitoring module are composed of protocol converters, multi-function controllers, various measurement sensors, and corresponding control execution units and intelligent control units of smart devices, each of which has an intelligent data processing and control function. The monitoring unit is composed of a multi-function controller (multi-serial port card) and is installed on the monitoring host to complete transmission of various data collected by the monitoring module to the monitoring center host; a multi-function data controller can connect various measurement sensors for acquisition and data transmission.
The monitoring module is a series of signal acquisition units, measurement sensors, protocol converters and corresponding intelligent controllers for controlling actuators and smart devices.
