Fig. 1 is the utility model structural representation.
As shown in Figure 1, this device 1, charge in batteries case 2, accumulator 3, load 4, voltage sensor 5, bidirectional current sensor 6, controller 7, display 8, collecting unit 9, computing unit 10, prewarning unit 11.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1; A kind of city rail vehicle battery condition supervising device; Be electrically connected with charge in batteries case 2, accumulator 3 and load 4 on the train, power supply is connected on the input end of charge in batteries case 2 and the car, and the output terminal of charge in batteries case 2 is connected with load 4 and this device 1; Be used for to car load DC110V load 3 power supplies, simultaneously to this device 1 output DC24V power supply.This device 1 is electrically connected with charge in batteries case 2 through the DC24V connection terminal, and this device 1 is electrically connected with accumulator 3 and load 4 through the DC110V connection terminal.During the power supply normal power supply, charge in batteries case 2 is given load 4 power supplies accumulators 3 chargings simultaneously onboard, and when power supply on the car can not normal power supply, accumulator 3 supplied power for load 4 through these devices 1 earlier again.
This device 1 comprises voltage acquisition unit, current acquisition unit, CompactRIO-9072 controller 7, display 8.Wherein, voltage acquisition unit adopts voltage sensor 5, is used to detect the sparking voltage value of accumulator 3.The current acquisition unit adopts bidirectional current sensor 6, is used to detect the charging current and the discharge current value of accumulator 3.The output terminal of voltage acquisition unit and current acquisition unit is connected with the input end of controller 7, and the output terminal of controller 7 is connected with display 8.Display 8 is used for the demonstration and the alarm of accumulator 3 capacity.
Charge in batteries case 2 gives car load DC110V load 4 power supplies through cable 203, and cable 203 is at first through the bidirectional current sensor 6 in this device, and then is connected with accumulator 3 through overvoltage sensor 5.Wherein, bidirectional current sensor 6 can be judged the trend of electric current, can judge that promptly accumulator 3 current states are charging or discharge, thereby calculate for the accumulator capacity in later stage the data support is provided.When using accumulator 3 as load 4 power supplies, cable 203 picks out the back from this device 1 and is connected with the train bus, as the energy source of train DC110V load 4.The current signal that controller 7 in this device 1 is gathered two-wire current sensor 6 is as a standard judging that accumulator 3 capacity rise or reduce.
In collecting unit 9, also comprise a comparison module; Be used for and preestablishing the voltage reference value and the current reference value that are stored in collecting unit 9 and compare from voltage sensor 5 and bidirectional current sensor 6 detected magnitudes of voltage and current value, and then definite accumulator 3 initial capacities.The charging and discharging currents value that controller 7 is gathered according to collecting unit 9 and sparking voltage value and predefined voltage reference value and current reference value compare two initial values of setting accumulator 3 capacity numerical value: maximal value and minimum value.When accumulator 3 charging currents are lower than current reference value, accumulator 3 capacity at this moment are made as 99%; When sparking voltage is lower than voltage reference value, accumulator 3 capacity at this moment are made as 1%.So just avoided the inaccurate drawback of the artificial setting of initial value.Wherein, current reference value is also different according to the characteristic reference value of different battery sizes with voltage reference value.
Because the inherent characteristic of accumulator 3 has determined its nonlinear relationship (two ends change very fast, and intermediate change is very slow), so all can not accurately represent its actual capacity with charging electric current or sparking voltage.For this reason; Original definition according to accumulator 3 capacity; In the present embodiment, adopt the mode recording capacity that accumulator 3 charging and discharging currents is carried out integration, that is: deduct its instant discharge current value with accumulator 3 initial capacities time per unit in discharge process; In charging process, add its instant charging current value, the accumulator capacity that obtains is so relatively pressed close to its actual capacity.That is:
P(n)＝P(n-1)+I(n)
Wherein: n is (second) for sometime, improves precision if desired, can get littler chronomere;
N-1 was the last time;
P (n) is current capacity, converts the same chronomere with n to;
P (n-1) is a last time capacity;
I (n) is current current value, during charging be on the occasion of, be negative value during discharge;
Result of calculation is converted to Ah again and gets final product.
Simultaneously, in controller 7, according to actual needs; Pre-set accumulator 3 capacity-warnings point; Other early warning points of a plurality of level generally can be set, and as setting early warning point such as 10%, 20%, 30%, early warning point and the accumulator 3 existing capacity that calculate through computing unit 10 compare; And according to actual result relatively; Through the communication between controller 7 and the display 8, current states is transferred in the display 8, display 8 shows in real time according to the content of transmission or carries out corresponding early warning.The driver can conveniently understand the state of current accumulator 3 according to display 8 content displayed, thereby guarantees the normal operation of vehicle.
As stated, in conjunction with the given scheme content of accompanying drawing, can derive the similar techniques scheme.In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
