Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment:
Structure of the present utility model comprises single-chip microcomputer as shown in Figure 1, and the human body that is connected on single-chip microcomputer exists signal transducer, light-inductive circuit, electric light drive circuit.Single-chip microcomputer also is connected with a watchdog circuit, disorderly flies and crashes in order to prevent Single Chip Microcomputer (SCM) program, causes system works abnormal.
In order to enlarge the signal range of receiving, human body exists the induction end of signal transducer to be conical surface shape.Human body exists and is packaged with three pins on signal transducer, as shown in Figure 2, No. 1 pin is the power supply signal end that is connected to positive source, the ground signalling end of No. 2 pins for being connected with power cathode, No. 3 pins are signal output part, and human body exists signal transducer to be connected with single-chip microcomputer by signal output part.Be provided with pull-up resistor between signal output part and single-chip microcomputer, an end of described pull-up resistor is connected with the positive pole of power supply, and the other end is connected with signal output part, single-chip microcomputer respectively.Also be provided with electric capacity between signal output part and single-chip microcomputer, the negative pole of described electric capacity is connected on the negative pole of power supply, and the positive pole of described electric capacity is connected with signal output part, single-chip microcomputer respectively.
As shown in Figure 3, the light-inductive circuit is the tertiary voltage comparison circuit that light sensor and voltage ratio form than chip.
As shown in Figure 4, the electric light drive circuit comprises six reversers, photoelectrical coupler and the electric light that is connected successively, and described hex inverter is connected on single-chip microcomputer.The signal that six reversers can send single-chip microcomputer fully amplifies, and in order to drive photoelectrical coupler, photoelectrical coupler can be isolated strong and weak electricity, and anti-external interference performance is good.
The utility model course of work is as follows:
