Uninterruptible power supply and DC power-line maintenance and management of – uninterrupted power supply, DC power supply – Electrical Industry
UPS is targeted at China Power Grid environment and network monitoring and network systems, medical systems on the Power supply Reliability requirements, overcome in large computer networks Centralized Power Supply Power supply caused by worsening environmental problems, to new digital technology developed in the third foundry frequency pure-line intelligent UPS. DC , Is formed to maintain steady current circuit devices. Such as batteries, battery, DC Generator And so on.
UPS and DC power supply is important to protect the equipment business, the traditional maintenance and management include: the appearance of routine inspection, periodic replacement of batteries, filter capacitor, fan and other wearing parts, overhaul, so do cell activation; transformation or by updating equipment, using advanced tools to test battery performance. This high input costs, management companies, maintenance staff workload and difficult to control the equipment operating status and real-time critical data, equipment, accident prevention and less. Implementation of the online maintenance to avoid the shortcomings of traditional methods to obtain good efficiency.
Computer maintenance management system online (A) of the system components 1, Master Control Station (background). By the monitoring stations, engineering and maintenance stations, system interface, etc., and use of management and analysis software processing the data received through the Web publishing. Engineering and maintenance personnel can view the server log of all the factory-line equipment condition and history complete, real-time data analysis statistics.
2, field device controller (ES). According to on-site equipment needs, alternative monitoring apparatus or equipment operating status information color collection instrument (EII). EII via RS-232/485 port and power meter, battery acquisition module, DC panel, UPS and other intelligent devices Communicate , Will monitor the data into packets that meet the communication protocol, access to local area network, sent to the main control room server. Integrity of the ES includes the following sections.
(1) system host. Serial channel from the downlink, data processor, display, uplink serial channels. Downstream channel through RS-485 serial bus access battery voltage acquisition module, data collection, management voltage acquisition module, data processor for data decompression, data computing, storage management, part of the processed data sent to display, the other from upstream sent to the serial channel protocol processor, or pass on a layer of management system.
(2) data acquisition module group. According to user needs to determine requirements and configure the appropriate data collection instrument collection, usually by the battery voltage acquisition module, current, temperature, power etc., the module isolation well insulated and strong, reliable and safe. Data collection can be grouped, each module can be collected on the number of battery voltage, can be equipped with current, temperature Sensor , Modules and systems generally use the RS-485 host connection.
(3) protocol handler. A protocol handler interface board, deal with various communication protocols. Can be realized: the host to send the battery voltage, current, temperature and other information coded according to the agreed protocol, packaged, sent to the remote server; the remote server to issue the remote control, remote transfer instructions issued to the host through the decoding, real-time control.
(4) discharge module. Can quickly detect the battery DC resistance, instant test battery performance, high-power discharge module provides instant high-current shock loading.
(5) remote server. Computer data communications within the LAN, remote access through the local gang scene, battery monitoring system, receiving, analyzing data, data dissemination through the Web server.
3, communications network. Networking field devices and sub-stations (Acquisition and Monitoring Station), data communication using optical fiber as the backbone to form the whole plant UPS and DC power-line monitoring of local area network.
