Description

A kind of accumulator on-line monitoring system based on technology of Internet of things
Technical field
The utility model relates to the communications industry, is a kind of accumulator on-line monitoring system based on technology of Internet of things to the communications industry.
Background technology
Battery pack is the important composition part that DC uninterrupted power supply is realized in the base station, and its investment and switch power supply equipment are suitable basically.What communication base station adopted at present mostly is the valve controlled sealed lead-acid accumulator (being called for short the VRLA battery) that the twentieth century end grows up.Owing to adopted valve controlling sealed structure, need not add acid, add the water maintenance, no acid solution, acid mist release, and can install with machine room with equipment.Because characteristics such as volume is little, in light weight, self discharge is little, lack maintenance, the life-span is long, esy to use, safe and reliable receive praises from customers.But we must see that but the basic electrochemical principle of this battery still becomes on the one hand, thereby not only no change of its intrinsic electrical characteristics requirement, require tighter on the contrary; This on the other hand battery is at the popularization initial stage; The instructions of producer is referred to as " non-maintaining " battery with this battery sometimes more or less; Causing partly, the maintainer thinks that this battery does not need to safeguard; Make battery service and detection can not get due attention, this misleading also has deep effect so far.
The base station accumulator is from present operating position, and the ubiquity accumulator capacity descends too fast, and serviceable life is short, and the accident of falling the station takes place again and again.From the present quality of the large-scale valve-regulated sealed cell manufacturer production battery of domestic several families, should satisfy each Carrier Requirements, though difference to some extent on each manufacturer production accumulator quality, performance.The qualitative factor of accumulator should not be influence each main cause that operator's base station accumulator capacity decline is too fast, shorten serviceable life at present.From composite factors such as valve controlling sealed battery product structure, properties of product, base station accumulator use inspection of the scene of a crime situation; In conjunction with exchange station operating position; After valve controlling sealed battery under normal circumstances uses 1~4 year; Its capacity descends would not be so fast, causes accumulator capacity decline main cause too fast, that shorten serviceable life in base station should be its base station environment for use and safeguard relevant.
Cause accumulator capacity decline main cause too fast, that shorten serviceable life in base station to be:
The first, the base station frequently has a power failure, power off time is long, power off time is irregular, and accumulator is is frequently discharged and recharged;
The second, that parameter is set is unreasonable for Switching Power Supply, and base station accumulator under-voltage protection is provided with brownout, and resetting voltage was provided with low, made accumulator overdischarge even degree of depth overdischarge phenomenon occur, aggravated the accumulator negative plate sulfation from another point of view;
The 3rd, the base station environment for use is more abominable.After the base station has a power failure, because no air-conditioning progressively rises the base-station environment temperature.Perhaps because the air-conditioning fault, make the base station indoor temperature higher, thereby reduced accumulator serviceable life;
The 4th, after the base station had a power failure, battery discharging did not in time replenish electricity to final voltage, will cause battery capacity to descend and the shortening in serviceable life yet;
Although; These problems that operating office exists with accumulator; But we are the mainly maintenance system of communication operator and maintainer's outfit at present, can't guarantee to find in time the problem of accumulator appearance, in time to its maintenance; In time behindhand battery is changed, avoid the generation of station accident.
This on-line monitoring equipment to the base station accumulator overcomes the above problems.When accumulator went wrong, the prompting maintainer safeguarded or changes battery, when having a power failure, provided the disconnected station time of estimating.
The utility model content
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of accumulator on-line monitoring system based on technology of Internet of things is provided, and it is applicable to the battery detection of communications industry base station.The main information such as monomer battery voltage, internal resistance of single cell, electric current, power supply temperature of gathering, and carry out battery altering through these information and make a strategic decision, back power supply duration is estimated with having a power failure.
The utility model solves the technical scheme that its technical matters adopts: this accumulator on-line monitoring system based on technology of Internet of things; Comprise battery current sampling module, information man-machine interaction load module, MCU processing module, monomer voltage acquisition module, clock module, cell discharge module, battery temperature acquisition module, battery sampling interface, RS232 transmission interface, power supply supplying module nine big modules; Wherein the battery current sampling module is connected with the MCU processing module; Information man-machine interaction load module is connected with the MCU processing module; The power supply supplying module is connected with battery temperature acquisition module, battery current sampling module, information man-machine interaction load module, MCU processing module, clock module respectively; Monomer voltage acquisition module, cell discharge module are connected with battery through the battery sampling interface and carry out data sampling, and the MCU processing module links to each other with central platform through the RS232 transmission interface.
Said battery current sampling module is installed on the battery line, and main equipment then is installed in the communication facilities cabinet in the base station, and the battery sampling interface joins through without hindrance line and 24 joint cells.
Said power supply supplying module adopts Switching Power Supply-48V as the input power supply, obtains the MCU working power, the supply module of adjunct units such as human-computer interaction module after handling through the power supply supplying module;
The effect that the utility model is useful is: the purpose of the utility model is to solve base station accumulator remote performance test, and relevant test data is provided.The main information such as monomer battery voltage, internal resistance of single cell, electric current, battery temperature, charging and discharging state of gathering, and carry out battery altering through these information and make a strategic decision, to estimate with the back power supply duration that has a power failure, battery capacity is estimated.
