Detailed description
In order to make the purpose and advantages of the present application more clear, the present application will be described in detail below with reference to the embodiments.
It should be understood that the following words are only used to describe one or several specific implementations of the present application and do not specifically require to strictly limit the scope of the present application.
As shown in the drawings, in the present embodiment, the inverting end of the first operational amplifier Ul and the inverting end of the second operational amplifier U2 use the power supply settings to fix the reference signal, the emitter of the first triode Q1 is directly connected to the non-inverting end of the second operational amplifier U2, the first operational amplifier Ul is used to output the load start signal, when the first operational amplifier Ul outputs, the signal is fed back to the non-inverting end of the second operational amplifier U2 through the first triode Ql. The second operational amplifier U2 1s used to output the detection signal, when the second operational amplifier
U2 outputs, the second MOS tube Q2 is turned on. The first relay K1 is used for signal isolation. After the second MOS tube Q2 is turned on, the coil of the first relay K1 and the auxiliary contact of the first relay K1 are closed. The first connection terminal P1 is used to connect the load. The first resistor R1 collects the load current at the first connection terminal P1 and feeds it back to the base of the third triode Q3 for amplification. The second resistor R2 cooperates with the first resistor R1 to set the amplification factor. The amplified signal output by the emitter of the third triode Q3 is converted by the third resistor R3. The fourth resistor R4 is used for current limiting, and the control chip collects the signal from the third resistor R3 to achieve parameter acquisition. Administrator can directly re-adjust the overcurrent parameters of the electrical connector based on this parameter without the need for step-by-step actual measurement.
In the embodiment, because the overcurrent of the electrical connector uses metal sheets with different expansion coefficients, when the load starting current is large, the signal acquisition needs to be limited by piezoelectric elements, and the resistance of piezoelectric elements is infinite in normal short circuit overcurrent, the subsequent judgment signal is not easy to collect, so the fifth resistor RS and the first resistor R1 are allowed to delay the start signal output by the first operational amplifier Ul. The second operational amplifier U2 outputs a detection signal, and the third operational amplifier
U3 replaces the start signal input from the non-inverting end of the first operational amplifier Ul to ensure that the start signal is still valid after a delay. The start signal input of the third operational amplifier U3 is input through the second connection terminal P2, the seventh resistor R7 and the eighth resistor R8 are used for positive feedback of the third operational amplifier U3, the tenth resistor R10 is used to eliminate the loop when the non-inverting terminal signal of the third operational amplifier U3 has no input signal. The ninth resistor R9 and the tenth resistor R10 are also used for the signal input of the non-inverting terminal of the third operational amplifier U3 when the third operational amplifier U3 has no output. When a signal is input to the second connection terminal P2, the signal is fed back to the non-inverting terminal of the third operational amplifier U3 through the eighth resistor R8, and the third operational amplifier U3 outputs. When the start signal is not input due to time delay, the output signal of the third operational amplifier U3 is fed back to the non-inverting terminal of the third operational amplifier U3 through the seventh resistor R7, thereby the signal output by the first operational amplifier U1 is fed back to the non-inverting terminal of the second operational amplifier U2 after being delayed by the fifth resistor R5 and the first capacitor C1 to prevent failure, after the second operational amplifier U2 outputs the signal, it detects and collects the load current to remove the piezoelectric element to prevent the signal from being difficult to collect during a short circuit.
In the present embodiment, in order to replace or retest the same load, the electrical connector overcurrent threshold is re-adjusted. When the control chip outputs a start signal to the second connection terminal P2, it also inputs a signal to the timing module.
When the timing module outputs a signal to the third connection terminal P3 after timing, the coil and auxiliary contact of the second relay K2 are closed, and the signal is fed back to the third operational amplifier U3. The signals from the non-inverting terminal and the inverting terminal of the third operational amplifier U3 are sent to the ground terminal loop through the auxiliary contact of the second relay K2. The third operational amplifier U3 has no output, and the first operational amplifier Ul and the second operational amplifier U2 also stop outputting. At this time, the input can be re-detected when the second connection terminal P2 is input.
In the present embodiment, it is considered that the overcurrent threshold of the electrical connector needs to be manually adjusted after the load is replaced or re-tested, and taking into account the real-time following adjustment method, when the load has overcurrent, the threshold of the electrical connector will also be directly set to the upper limit, so the connection between the third resistor R3 and the control chip is removed, and Po is allowed to feedback the overcurrent threshold parameter that needs to be adjusted for the electrical connector. The sixth digital potentiometer U6 and the eleventh resistor R11 automatically adjust the signal amount fed back by P6, the fourth transistor Q4 and the thirteenth resistor R13 are used to feed back the current signal of PG to the fourth operational amplifier U4, which is the PG signal quantity after the last adjustment. The fourth operational amplifier U4 is used to compare the last adjusted overcurrent threshold parameter with the power parameter detected this time, which is the current parameter fed back by the third triode Q3. The fifth MOS tube Q5 is used to invert the output of the second operational amplifier U2, and the twelfth resistor R12 is used to pull down the wake-up signal terminal signal of the sixth digital potentiometer U6. When the second operational amplifier U2 does not output a detection signal, the sixth digital potentiometer U6 is in sleep mode, and the fourteenth resistor R14 is used to adjust the signal pull-down. When the third triode Q3 feeds back the current signal, it is converted into a voltage through the third resistor R3 and fed back to the inverting terminal of the fourth operational amplifier U4, the fourth operational amplifier U4 compares the voltages at the non-inverting terminal and the inverting terminal. The high or low level signal 1s output through the fifth connection terminal P5 to the adjustment signal terminal of the sixth digital potentiometer U6 for upward or downward adjustment, and at the same time, the fifth MOS tube Q5 is turned off. The wake-up signal terminal signal connected to the fourth connection terminal P4 is automatically adjusted through the twelfth resistor R12 loop and the sixth digital potentiometer U6, which allows the load to automatically input the overcurrent threshold adjustment signal of the electrical connector after replacement or re-detection. At the same time, due to the output of the third operational amplifier U3, the threshold of the electrical connector will be directly set to the upper limit to avoid overcurrent during follow-up. The first operational amplifier Ul, the second operational amplifier U2, the fourth operational amplifier U4, and the fifth operational amplifier US are connected in series through the fifteenth resistor R15 to the seventeenth resistor R17 to provide a reference signal. The second
MOS tube Q2 is powered by voltage division through the eighteenth resistor R18 and the nineteenth resistor R19. The second resistor R20 is used for the gate circuit of the fifth MOS tube Q5 and the second MOS tube Q2. The twenty-first resistor R21 and the twenty-second resistor R22 are used to supply power to the fifth MOS tube Q5, and the twenty-third resistor R23 prevents the leakage current of the first triode Q1 from causing residual current in the loop.
