Embodiment
As shown in Figure 1, control circuit is made up of the sampling element, pre-amplification circuit, AC/DC change-over circuit 5, dc amplification circuit 2, single-chip minimum system 1 and the display module 3 that connect successively, and sampling element, pre-amplification circuit are formed sample circuit 4; DC power supplier 6 provides stable operating voltage to control circuit.
As shown in Figure 2, sampling element and pre-amplification circuit connect to form sample circuit 4, and it is the sample electric current of load of the AC current transformer L of IWCT-5A/5mA that sampling element is selected model for use.Characterisitic parameter and load curve according to current transformer, the maximum range of setting according to this socket is 2200W again, be that electric current is 10A (supposing that line voltage is 220V), simultaneously in order to guarantee certain ability that transfinites, sampling element is selected the sample current signal of load of AC current transformer L for use, and a resistance R in parallel 20 converts current signal to voltage signal between current transformer and pre-amplification circuit.Resistance R 20 is 10 Ω.For the load current of 0~10A, voltage is output as 0~10mA * 10 Ω, i.e. 0~0.1V like this.It is 0~1V that pre-amplification circuit adopts integrated operational amplifier U4A to amplify 10 times from the voltage signal of sampling element output.
AC/DC change-over circuit 5 is that alternating voltage 0~1V that sample circuit 4 produces is converted to direct voltage, mainly is made of integrated transporting discharging TL062CP and peripheral circuit.To be that stopping direct current is logical exchanges for capacitor C 9 and C1, and diode D2 and D4 and operational amplifier constitute accurate halfwave rectifier, R18 and C12 formation RC filter circuit, and C10, C13 and R25, R26 are used for carrying out phase compensation.Valid value range 0~the 1V of input AC is output as direct current 0~1V through the AC/DC change-over circuit.
For good, the amplitude stabilization of the linearity that guarantees signal, added one-level dc amplification circuit 2 in the back level of AC/DC change-over circuit, and selected big filter capacitor C8 for use, then after resistance R 13 dividing potential drops as the signal that reads of single-chip microcomputer.Amplify through this level, can make the direct voltage output of the ADIN maximum 4.3V of acquisition of end (1V * 4.3),,, ADIN is adjusted in the scope of 0~2.5V by regulating R13 because the AD of single-chip microcomputer MSP430 selects for use is inner 2.5 a reference sources.The one-chip machine port that the direct current signal of importing from the ADIN pin passes through to be connected enters the CPU inside of single-chip microcomputer.
