Description of drawings
Fig. 1 is the battery module structural representation;
Embodiment
Classic method adopts ups power to satisfy the cabinet system uninterrupted power supply as the back-up source of cabinet system, and structure of the present invention difference is to adopt electric battery to power to cabinet system as the back-up source module.
As shown in drawings, comprise electric battery, capacity monitor module and alarm monitoring module in this battery module,, when breaking down, can in time notify the machine room maintainer to guarantee electric battery by battery module is set.Guarantee the operate as normal of whole cabinet system.
Capacity monitor module: the processor unit and the data acquisition unit that have oneself.Therefore, it uses with supervisory system as this locality.This capacity monitor module is mainly finished the function of following several respects: online detection, the all/float mode of residual capacity changed, the monomer terminal voltage is tested and behindhand battery detects, the cell body temperature test.Its overall realization as shown in Figure 1.
The whole hardware configuration of capacity monitor module: processor module is the core of capacity monitor module, has guaranteed that not only mass data is carried out high speed analysis to be handled, and has realized the preservation query function to data.As shown above, in the data acquisition module, because the data that need to handle in the capacity monitor modular unit all have special requirement to precision, (be generally m Ω level such as measurement to the electric battery internal resistance, and enough figure places must be arranged), be the low time varying signal of slow variation simultaneously owing to electric battery internal resistance, voltage, therefore adopted 16 A/D converter, it has automatic zero adjustment, the range function of calibration automatically, thereby can guarantee very high measuring accuracy, and have a SPI interface, can be easily and interface microcontroller.Be provided with the communication interface of RS485 in the capacity monitor module, with the situation swap data to communicate by letter between the FEP primary processor.The online measuring ability of residual capacity, the reliability of it and whole electric power system is closely related, and the electric battery dump energy is high more, and then system reliability is high more, otherwise otherwise.Therefore how can not influence again under the situation of the operate as normal of consumer at consuming cells group energy neither, the dump energy of real-time on-line monitoring electric battery will have important and practical meanings.Because electric battery is a complicated electro-chemical systems, when it moved under the different loads condition, electric battery reality can be also different for the electric weight that discharges.Along with the electric battery increase of service time, its actual releasable electric weight also will descend.In the past, often judge what of the quality of accumulator and its dump energy, but this method there is significant limitation according to the terminal voltage of electric battery.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 bigger.What the present invention adopted is the internal resistance method, because the correlativity of internal resistance and battery capacity is very good, related coefficient can reach 88%.Therefore, can predict its dump energy more exactly by measuring the internal resistance of cell.Battery charges (being full of) fully and discharge is when (having put) 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.
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 concerning the battery of online use, and the method is to the systematic influence minimum, and can accurately measure in the whole operating period of battery.
The alarm monitoring module: having oneself data acquisition unit, data processing unit, alarm unit and communication unit, is the monitoring management to electric battery, when electrical network has a power failure suddenly, ensures the normal power supply of cabinet system.Whether working properly it is, directly relates to the safety of equipment such as computing machine, network in the rack and the data security of infosystem, 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 group can not regular picture, causes quitting work the load power down when electrical network has a power failure suddenly.Even more serious is, and some internal resistance of cell raises 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, the voltage landing is quickened during discharge, and effective preparation time is reduced, and needs in time to change.The alarm monitoring module is developed at above demand, by each piece battery in the electric battery is monitored in real time, in time find overtension or (internal resistance increase) fluctuated, and the phenomenon of brownout (capacity reduction), in time report to the police, and provide essential analysis to historical data, accomplish correct maintaining, thereby guarantee the operate as normal of server cabinet system electric battery.
The alarm module function, (1) carries out on-line sampling to the voltage of each piece battery in the electric battery, monitors the voltage fluctuation situation of each batteries in real time; (2) monitor dispatch from foreign news agency supply voltage, electric current in real time; (3) real-time sampling server cabinet temperature, humidity and smog sensing data.(4) the various data that collect are carried out screen and are presented and high low threshold (scope amount) judgement, and the person of transfiniting is carried out sound and red literal display alarm; (5) network Centralized Monitoring carries out display alarm and control to sampled data, links to each other with computing machine by the TCP/IP network, carries out the dump and the statistical study of historical data.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
