Embodiment
As shown in Figure 1, the apparatus for testing weeping of the utility model comprises that signal generator 101, the first leakages detect lead 102, the second leakages and detect lead 103, and signal processing unit 104.The end that first leakage detects lead 102 is connected with signal generator 101, and the other end is open circuit.The end that second leakage detects lead 103 is connected with signal processing unit 104, and the other end also is an open circuit.First leakage detects the open end of lead 102 and the open end of second leakage detection lead 103 is positioned at leakage surveyed area 105, and the two does not connect.But when in the leakage surveyed area 105 leakage being arranged, then possibly between two open ends, form electrical connection.At this moment, the signal of signal generator 101 generations can be transferred to second leakage and detect lead.Under some configuration, the signal that is transferred to second leakage detection lead can be directly inputted to battery control system.When leakage not occurring, battery control system can not receive the signal that detects lead from second leakage, thereby does not have leakage in the identification battery.If battery control system receives the signal that detects lead from second leakage, explain then to have occurred the phenomenon of leakage in the battery that battery control system needs in time to break off electric energy output, guarantees the security of power brick.Under many circumstances, the signal that is transferred on second leakage detection lead does not meet the requirement that is directly inputted to battery control system, for example possibly be because the insufficient strength of signal.Therefore, it is not to be directly connected to battery control system that second leakage detects lead, but that kind shown in the image pattern 1 is connected to signal processing unit 104.The signal that is input to signal processing unit 104 has been carried out certain processing, after for example amplifying, just further sends to follow-up processing unit (for example battery control system).In addition, signal processing unit 104 also to the received signal intensity carry out preliminary judgement.One threshold value can be set,, the phenomenon of leakage and not serious be described then, can ignore if the intensity of the signal that receives is lower than threshold value.Have only the intensity of signal just to explain the phenomenon of leakage that need obtain handling has taken place greater than threshold value; This moment, signal processing unit sent signal to battery control system; Inform this leakage situation, and battery control system being handled accordingly, for example is the electric energy output of breaking off battery.
The signal generator here can be exactly a power supply, for example vehicle-mounted 12V power supply.In this case, if leakage takes place, the signal that is input to signal processing unit 104 is a continuous signal.Perhaps signal generator also can produce other forms of signal, for example discontinuous signal.
Fig. 2 is the partial enlarged drawing of leakage surveyed area 105 among Fig. 1.If first leakage detects lead 102; Second leakage detects lead 103 and is provided with according to mode shown in Figure 2; If only have leakage this moment in dashed region 201, then can not detect by device to be detected, be electrically connected because between 2 open ends of 2 leakages detection leads, form.Therefore, for the phenomenon of leakage in certain zone is detected fully, the distance of then being separated by between the open end of leakage detection lead is enough little, but area coverage is enough big again.Fig. 3 shows a kind of configuration that the leakage that realizes above-mentioned requirements detects the open end of lead, and wherein each open end has many parallel linear leads, and the parallel lead of 2 open ends is crisscross arranged.Can see, if exist leakage just can be detected in the dashed region 201 this moment.Fig. 4 shows another configuration that leakage detects the open end of lead, and wherein each open end has many parallel waveform leads.
Fig. 5 shows an embodiment of the utility model, and apparatus for testing weeping wherein comprises power supply Vb, and first leakage detects lead 501, the second leakages and detects lead 502, and by operational amplifier and one group of signal processing unit that electricity group R1, R2, R3 form.Because the condition of different such as distance between the size of power source voltage, leaking liquid amount, two leads are transferred to influence the size of signal processing unit input Vin signal; Can find the phenomenon of leakage of target in order to make power control unit; Need amplify Vin, and parameters such as amplification coefficient can be through freely selecting the setting of R1, R2 and R3.
Though introduced the preferred embodiment and the device of the utility model in the detailed description of accompanying drawing and front; But should be understood that; The utility model is not limited to the concrete embodiment of announcing, under the prerequisite of the scope that does not depart from the claim regulation, still multiple modification and distortion can be arranged.
