The battery check device major function of the present embodiment detects the voltage of check point in electric battery, can judge signal when the check point change in voltage detected then exports for the alarm of supervisory system process; Can judge that signal judges that whether the battery in electric battery is stolen according to alarm for supervisory system.The present embodiment battery check device can detect the voltage of at least two check points in electric battery, the check point such as can choosing two check points or three check points or more than three on the battery pack detects, but the check point chosen must meet: the voltage of at least two check points is different, namely above-mentioned said at least two check points with different relative potentials difference; The check point of the check point and an output LOW voltage that such as can choose an output HIGH voltage on the battery pack detects; Such as can choose again three check points exporting high, medium and low voltage on the battery pack to detect.What the mode choosing check point in the present embodiment can avoid existing two lines to detect choosing the positive and negative limit of electric battery to cause as check point cannot detect the problem with alarm effectively for only stealing intermediate cell; In the present embodiment, the change in voltage of arbitrary check point all can cause alarm output circuit to export and show that the stolen alarm of battery judges signal, ensure that testing result reliability and accuracy, and can notify that user's battery is stolen in time, thus enable related maintenance personnel carry out maintenance in time to avoid larger loss, facilitate public security organ to get involved process in time simultaneously.
The battery check device of the present embodiment can detect the voltage of check point in electric battery by detection line, a corresponding check point of detection line; When stealing one's share of expenses for a joint undertaking and stealing, take battery away and be easy to cut off a wherein detection line, such battery check device will detect that the change in voltage of this check point produces corresponding alarm and judges that signal sends to monitoring unit, judge that battery is stolen by monitoring unit, then alarm or notify user; In addition when stealing one's share of expenses for a joint undertaking and taking battery away but do not cut off detection line, in electric battery, the voltage of each check point also can change, in the present embodiment, battery check device will detect this change, produce corresponding alarm and judge that signal sends to monitoring unit, judge that battery is stolen by monitoring unit, then carry out alarm or notify user.
Consider the compatibility of the present embodiment battery check device, the alarm that alarm output circuit described in the present embodiment battery check device is used for the output voltage of described detection decision circuitry to be converted to dry contact form judges signal.
The alarm that the present embodiment battery check device can export dry contact form judges by supervisory system, signal is to on-the-spot arbitrary supervisory system with dry contact measuring ability, judges that whether battery is stolen; Improve compatibility and the flexible Application of pick-up unit.
Preferentially, choose three check points electric battery with the high, medium and low relative potentials difference of relative potentials in the present embodiment to detect.Below by be detected as example to three check points electric battery with the high, medium and low relative potentials difference of relative potentials so that the battery check device of the present embodiment to be described:
As shown in Figure 3, be a kind of base station storage batteries theft detection system, comprise: battery pack, detection decision circuitry, alarm output circuit and communication base station monitoring system; Wherein detection decision circuitry and alarm output circuit constitute battery check device in the present embodiment; Three input ends detecting decision circuitry are connected on the relative noble potential binding post of battery pack, intermediate potential binding post and electronegative potential binding post respectively by detection line.4 joints 12V electric battery (also can be applicable in other various electric battery such as 2V, 6V electric battery) often adopted for communication base station and electric power, its 3 modes of connection can be as shown in Figure 4; The wiring of noble potential check point is to be connected on the negative terminal binding post of battery pack maximum potential battery, the wiring of intermediate detection point is to be connected on midpoint potential binding post, and the wiring of electronegative potential check point is to be connected on the anode binding post of battery pack potential minimum battery.Need to be interpreted as that the connection shown in Fig. 4 is only an example of this application, 3 wiring can be any 3 points battery pack with relatively high, medium and low potential difference (PD) herein.The power-supply system adopted due to communication base station is generally-48V system, so under accumulator normal operation, with-48V for reference voltage, in Fig. 4, these three input end signal voltages are respectively 32V (VH), 12V (VL) and 24V (VT), relative to VL, all there is certain potentials poor, control the operation detecting decision circuitry.When battery is stolen, usual detection line can be cut off to be fallen on the ground; Some are understood to the stealer of technology, the battery that battery pack two ends are connected with power taking line may be retained, and intermediate cell is stolen; In this case intermediate detection line also can be cut off.As long as any velamen cuts off in three detection lines, its set potential disappears, detection decision circuitry running status all can change the alarm causing alarm output module to export expression battery stolen and judge signal, and communication base station monitoring system can clearly judge that battery is stolen.After battery is stolen, the alarm output module being core with node output function can by the voltage transitions of detection decision circuitry output for dry contact information uploads to communication power supply supervisory system; Requirement that dry contact signal is nonpolarity, its contact voltage can be selected according to service condition, is greater than practical application scene voltage and has surplus, do not have exact requirements as long as meet; Therefore can be compatible with any watch-dog flexibly, thus accurately and reliably realize alarm function.
Detect the circuit that decision circuitry can be core in order to triode in the present embodiment to realize; The circuit that alarm output circuit is core devices in order to relay realizes.
Be to be understood that, be only with triode, the relay detection decision circuitry that is core and alarm output module a kind of form realizing detecting the function of decision circuitry, the function of alarm output circuit in the present embodiment, these functions can also be had for other, device and the circuit structure thereof of the present embodiment detection decision circuitry and alarm output circuit function can be realized.
As shown in Figure 5, detecting decision circuitry in the present embodiment can comprise: the first resistance R1, and one end is connected with battery pack intermediate detection point signal VT, and the other end is connected with the negative pole of voltage stabilizing diode VD1.The positive pole of VD1 is connected in the base stage of NPN type triode VT1.Second resistance R2 one end is connected with battery pack noble potential check point signal VH, and the other end is connected to the collector of VT1.3rd resistance R3 is in parallel with the second resistance R2.The negative pole of counnter attack diode VD2 is connected with battery pack electronegative potential check point signal VL, and its positive side is connected with the emitter of VT1, is connected by the base stage of the 4th resistance R4 and VT1.
Be used in parallel with the 3rd resistance R3 of second resistance R2 provides suitable collector current to VT1, and in parallel use is the power consumption surplus considering resistance itself.First resistance R1 and the 4th resistance R4 dividing potential drop, for providing suitable ideal base drive current and voltage to VT1.Voltage stabilizing diode VD1 is used for providing suitable forward voltage to VT1, prevents because the external world surprisingly disturbs the misoperation of caused VT1.Diode VD2 is used for providing protection when VH signal wire and the reversal connection of VL signal wire to circuit.
As shown in Figure 5, the alarm output circuit of the present embodiment can comprise: relay K 1, and its coil control line anode is connected with battery pack noble potential check point signal VH, and negative terminal is connected with the collector of triode VT1.
The course of work of battery check device is as shown in Figure 5: when battery pack state is normal, the potential difference (PD) of each check point ensures that triode VT1 is in conducting state, and battery condition detection signal BT is 0V (namely its current potential is VL) relative to VL signal.After accumulator is stolen, if VH detection line is cut off, battery condition detection signal BT is vacant state.If HL detection line is cut off, then BT signal is pulled up, current potential same with VH.If VT signal wire is cut off (namely only stealing the situation of middle node battery), triode not conducting, BT signal is also pulled up, current potential same with VH.If three detection lines are all cut off, then battery condition detection signal BT is vacant state, all with the accumulator state similarities and differences under normal circumstances.In normal state, there is VH-VL pressure reduction at relay K 1 coil two ends, the actuating of relay, are off state between its normally closed contact ALM-NC and common port COM, are closure state between normally opened contact ALM-NO and common port COM.After accumulator is stolen, no matter be which kind of pilferage situation, no matter i.e. unsettled or same with the VH current potential of battery condition detection signal BT, the control coil two ends of relay K 1 are all without pressure reduction, relay is failure to actuate, be closure state between its normally closed contact ALM-NC and common port COM, between normally opened contact ALM-NO and common port COM, be off state; Now communication base station monitoring system will detect between the normally closed contact of relay K 1 and common port COM for closure state or be off state between normally opened contact ALM-NO and common port COM time will judge that accumulator is stolen, send alarm and notify that user's battery is stolen.
Further in order to can protective relay K1, the present embodiment can also on the basis of Fig. 5, the spike produced when increasing by a protection circuit for absorbing relay coil action.As shown in Figure 6, a diode VD3 in parallel with relay K 1 can be increased, the spike produced when absorbing relay coil action.The anode of diode VD3 is connected with the coil control line negative terminal (i.e. triode VT1 collector) of described relay, and the negative terminal of described diode VD3 is connected with coil control line anode (namely VH is connected).Relay exports normally closed contact ALM-NC, normally opened contact ALM-NO and contact common port COM.
It is noted that from reliability perspectives when using the circuit shown in Fig. 6, each device should stay enough enough surpluses, and derate uses: the second resistance R2 should note coordinating between its peak power with triode VT1 collector current with the 3rd resistance R3.The dividing potential drop of the first resistance R1 and the 4th resistance R4 will process according to the virtual voltage situation of accumulator intermediate detection point VT, and must meet the voltage after its dividing potential drop under normal circumstances can turn-on transistor VT1, also should be noted that resistor power problem simultaneously.The voltage stabilizing value of voltage stabilizing diode VD2 also will be determined according to this partial pressure value and VT1 conducting situation, effective conducting of VT1 under normal circumstances can be ensured, misoperation can not be caused because of the interference in the external world when accumulator intermediate detection point unsettled (not only detection line cut off).VD2 should be noted that its maximum direct current reverse voltage VR need be greater than VH-VL and leave surplus, could play a protective role when VH and VL reversal connection to circuit.For relay K 1, need to select coil rating operating voltage to be the relay of VH-VL; Need according to real work situation, the situation of especially on-site supervision selects operating voltage and the electric current of its contact simultaneously.For the VD3 with relay collaborative work, its maximum direct current reverse voltage VR also needs be greater than VH-VL and leave surplus.
