Referring to Fig. 1, the utility model comprises testing circuit 2, single-chip microcomputer 4, on-off circuit 3, suggestion device 5, filter capacitor 6, power supply 1, and wherein, suggestion device 5 one ends and single-chip microcomputer 4 join, and the negative pole of the other end and power supply 1 joins; Filter capacitor 6 one ends and testing circuit 2 join, and the negative pole of the other end and power supply 1 joins; Testing circuit 2 one ends are connected with single-chip microcomputer 4, and the negative pole of the other end and power supply 1 joins; On-off circuit 3 one ends are connected with single-chip microcomputer 4, and the other end is connected with testing circuit 2, wherein:

Testing circuit 2 is MXD7202ML chips.

Single-chip microcomputer 4 is that model is: the single-chip microcomputer of MSP430F2121, MSP430F2232, PIC16F690.

On-off circuit 3 is metal-oxide-semiconductor or transistor.

Suggestion device 5 is light-emitting device, sound-producing device, display device.Wherein light-emitting device is LED; Sound-producing device hummer, loudspeaker, loudspeaker, earphone; Display device is the LCD LCD.

Referring to Fig. 2, the concrete electric elements that adopt in the preferred embodiment of the present utility model: testing circuit 2 is that MXD7202ML chip U2, single-chip microcomputer 4 are that model is: the single-chip microcomputer U1 of MSP430F2232, build-out resistor are that resistance R 1, filter capacitor 6 are that metal-oxide-semiconductor T1, suggestion device 5 comprise the pilot lamp LED1 that is tilted to the right, the pilot lamp LED2 that is tilted to the left for capacitor C 1, on-off circuit 3, and power light is that LED3, power supply 1 are the direct supply of 3.3v or the charged lithium cells VCC of 3.6v.

The XOUT pin of one end of the resistance R 1 in the circuit and MSP430F2232 single-chip microcomputer U1 joins, 5 pin of the other end and MXD7202ML chip U2 are that the XOUT pin of MXD7202ML chip joins, thereby realize the communication between MSP430F2232 single-chip microcomputer U1 and the MXD7202ML chip U2.

The V-QX pin of the grid of metal-oxide-semiconductor T1 in the circuit and MSP430F2232 single-chip microcomputer U1 joins, pin joins the VCC (being power supply or anode) of source electrode and MSP430F2232 single-chip microcomputer U1, the VDD pin of drain electrode and MXD7202ML chip U2 joins, thereby make MSP430F2232 single-chip microcomputer U1 by control to the break-make of metal-oxide-semiconductor T1, realization is to the work whether control of MXD7202ML chip U2, when metal-oxide-semiconductor T1 conducting, MXD7202ML chip U2 work realizes taking aim at the tool status detection; When metal-oxide-semiconductor T1 disconnected, MXD7202ML chip U2 quit work, and realized the requirement of low-power consumption.Filter capacitor C1 is connected between the VDD pin of MXD7202ML chip U2 and the power cathode and reaches the filtering purpose.
