Description
Technical field
The present invention relates to accumulator monitoring field, more particularly, it relates to a kind of storage battery monitoring device and side
Method.
Background technology
Accumulator is as the vehicles and changes such as railway locomotive, subway, automobile, steamer, naval vessels, tanks
Power station, communication base station, the stand-by power supply of machine room and startup power supply, play particularly important effect, such as:
For railway electric locomotive, before locomotive rising bow is flowed, accumulator provide power supply for control circuit, with complete
Preparation before becoming locomotive to be flowed；Thered is provided power supply by accumulator for rising bow compressor, rise pantograph；Transport at locomotive
In row, once rectification controls power failure, can excise rectification and control power supply, storage battery power supply tie up
Holding locomotive failure to run, when locomotive is properly functioning, accumulator battery and electrical locomotive power parallel running, to locomotive
Rectification controls power supply and strobes, to reduce the ripple factor of rectification control power supply.For diesel locomotive:
When diesel engine does not works, set of cells auxiliary equipment on locomotive, control loop, lighting circuit is powered；
Being thered is provided electric energy when diesel engine starting by set of cells, starter-generator is as series excitation DC motor, by front
Change speed gear box universal drive shaft and pulling electric generator rotor, drive crankshaft of diesel engine to rotate；In locomotive normal course of operation
Strobe to controlling power supply, to reduce the ripple factor controlling power supply, improve the quality controlling power supply；
In locomotive operation when auxiliary generator fault, supply locomotive control electricity consumption, to maintain locomotive to answer acute fortune
Turn.
In locomotive, in general 4 joints of accumulator are one group of 12 battery case made of iron being installed on locomotive bottom,
Altogether by 48 batteries tandem workings, as shown in Figure 1.Owing to locomotive storage batteries working condition is the most severe: work
Making temperature range-40 DEG C～50 DEG C, electric current and the charging current of sparking is relatively big, also subject to lasting vibration
And impact, thus in locomotive, accumulator failure rate is high, the life-span is short, and it is unfavorable to cause the safe operation of locomotive
Impact.Locomotive storage batteries is monitored, grasps the duty of accumulator in time, can find in time
Backward accumulator is also changed, thus significantly improves battery service management level, improves locomotive operation
Reliability.
The common pointer instrument being installed in locomotive on control room operating board at present, only shows storage simply
The voltage of set of cells and charging and discharging currents, it is impossible to accumulator is effectively monitored.
And the equipment being monitored currently for common accumulator, it is divided into centralized and split type two kinds
Type:
(1) centralized accumulator monitoring equipment, an equipment realizes to detecting, show, store,
The functions such as warning, communication.
(2) split accumulator monitoring equipment, including a main frame and multiple stage from machine, main frame with respectively from machine it
Between be in communication with each other by wired or wireless mode.Completed to control by main frame, show, store, report to the police and appoint
Business, from machine under the control of main frame, detects a joint or a few batteries, and detection data is sent to
Main frame.
But, accumulator monitoring data cannot be sent out under locomotive environment by centralized accumulator monitoring equipment
Going, volume is the hugest, is not therefore suitable for locomotive storage batteries monitoring.
For split accumulator monitoring equipment, if main frame and each employing wireless communication mode between machine, although
It is not required to lay any order wire specially, but its power consumption is higher, and other equipment can be produced interference.Work as main frame
And when having wall or metal object to intercept between machine, main frame cannot communicate with from machine, is therefore not suitable for machine
Accumulator monitoring in car.
If main frame and each between machine by the communication cable communication laid, although its reliable communications, low in energy consumption,
Capacity of resisting disturbance is high, but it needs boring on battery case to burrow to lay communication cable, the most also cannot be
Use on locomotive.
