Embodiment:
A kind of method that prevents power failure of server cabinet system of the present invention adopts battery module to power to server cabinet system as the back-up source module; Battery module comprises battery pack, capacity monitor module and alarm monitoring module, and the capacity monitor module is connected with the alarm monitoring module and is connected and the data of monitoring battery group; Capacity monitor module and alarm monitoring module are all received on the supervisory control comuter; The capacity monitor module comprises processor module, data acquisition module, RS485 communication interface, monomer voltage test module, testing current module, internal resistance test module, temperature test module; Monomer voltage test module, testing current module, internal resistance test module, temperature test module all are connected on battery pack and the upper data acquisition module, and data acquisition module connects processor module, and processor module connects the RS485 communication interface; Monomer voltage test module, testing current module, internal resistance test module, temperature test module will be measured the related data transmission of battery pack to data acquisition module; Data acquisition module is transferred to processor module after with data acquisition; Processor module connects the RS485 communication interface; The RS485 communication interface connects on the supervisory control comuter; The alarm monitoring module connects and monitoring battery group and server cabinet system, and the alarm monitoring module links to each other with supervisory control comuter by the TCP/IP network.
The alarm monitoring module is carried out on-line sampling to the voltage of each piece battery in the battery pack, the voltage fluctuation situation of each batteries of Real-Time Monitoring; Real-Time Monitoring dispatch from foreign news agency supply power voltage, electric current; Real-time sampling server cabinet temperature, humidity and smog sensing data; The alarm monitoring module is carried out display alarm and control to sampled data, the various transfer of data that the alarm monitoring module collects are to supervisory control comuter, carrying out screen presents and high low threshold judgement, the person of transfiniting is carried out sound and red literal display alarm, carry out dump and the statistical analysis of historical data.
The capacity monitor module is used with supervisory control system as this locality; The capacity monitor module is mainly finished the function of following several respects: online detection, the all/float mode of battery pack residual capacity changed, the monomer terminal voltage is tested and behindhand battery detects, the cell body temperature test.
Processor module is the core of capacity monitor module, has guaranteed that not only mass data is carried out high speed analysis to be processed, and has realized the preservation query function to data.In the data acquisition module, owing to need data to be processed that precision is all had special requirement in the capacity monitor modular unit, (be generally m Ω level such as the measurement to the battery pack internal resistance, and enough figure places must be arranged), be simultaneously the low time varying signal of slow variation owing to battery pack internal resistance, voltage, therefore adopted 16 A/D converter, it has the function of automatic zero adjustment, range automatic calibration, thereby can guarantee very high certainty of measurement, and have a SPI interface, can be easily and interface microcontroller.Be provided with the RS485 communication interface in the capacity monitor module, with the situation swap data to communicate by letter between the supervisory control comuter primary processor.The online measuring ability of residual capacity, the reliability of it and whole electric power system is closely related, and the battery pack dump energy is higher, and then system reliability is higher, otherwise otherwise.Therefore how can not affect again in the situation of the normal operation of power consumption equipment at consuming cells group energy neither, the dump energy of real-time on-line monitoring battery pack will have important practical significance.Because battery pack is a complicated electro-chemical systems, when it moved under the different loads condition, battery pack reality can be also different for the electric weight that discharges.Along with the battery pack increase of service time, its actual releasable electric weight also will descend.In the past, often judge what of the quality of storage battery and its dump energy according to the terminal voltage of battery pack, but the method there is significant limitation.Along with cell degradation, its terminal voltage changes not obvious.Therefore, utilize the variation of terminal voltage to calculate that its dump energy has certain difficulty, error is larger.What the present invention adopted is the internal resistance method, because the correlation of internal resistance and battery capacity is very good, coefficient correlation can reach 88%.Therefore, can predict more exactly its dump energy by measuring the internal resistance of cell.Battery charges (being full of) fully and discharge is when (discharging) fully, and its internal resistance differs about 2 ~ 4 times.Along with the carrying out of battery charging process, internal resistance progressively reduces; Along with the carrying out of discharge process, internal resistance progressively increases.In addition, along with cell degradation, its internal resistance also increases gradually, and its dump energy also descends thereupon.The relation curve of the internal resistance of cell and dump energy as shown in Figure 2.
Because battery charges fully and fully when discharging the internal resistance rate of change more much bigger than battery terminal voltage rate of change (the terminal voltage rate of change is about 30% ~ 40%), so predict its dump energy with the measurement internal resistance of cell, much more accurate than the open circuit voltage method.The advantage of internal resistance method is that concerning the battery of online use the method is minimum to systematic influence, and can accurately measure within the whole operating period of battery.
The alarm monitoring module: battery pack is when electrical network has a power failure suddenly, ensures the vitals of cabinet system power supply.Whether working properly it is, is directly involved in the safety of the equipment such as rack Computer, network and the data security of information system, is one of important step of information system security production, must pay close attention.A kind of fault shows as some internal resistances of cell and raises, and having influence on whole battery pack can not regular picture, causes quitting work the load power down when electrical network has a power failure suddenly.More seriously some internal resistances of cell raises and fails in time to find to change, and can cause to press in the inner heat to increase and explode.Another kind of fault shows as, because inconsistent some battery capacity of battery parameter descends, voltage-drop accelerates during discharge, and effective preparation time is reduced, and needs in time to change.The alarm monitoring module is developed for above demand, by each piece battery in the battery pack is carried out Real-Time Monitoring, in time find overtension or (internal resistance increase) fluctuated, and the phenomenon of brownout (volume lowering), and alarm, and provide necessary analysis to historical data, accomplish the correct maintenance maintenance to battery pack, thereby guarantee the normal operation of server cabinet system.
Of the present inventionly a kind ofly prevent that its processing and fabricating of method of power failure of server cabinet system is very simple and convenient, shown in the by specification accompanying drawing.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
