Background technology
Fatigue is a kind of natural phenomena, is the self regulation and the defencive function of human body.Its generation is relevant with labor intensity, environment, health condition, emotion and job performance.Remove the method for subjective measurement fatigue, measuring tired method more objectively is from the angle of medical science, by medical instrument tester's brain electricity, electrocardio, myoelectric waveform to be tested and analyzed, thereby draw an accurate human-body fatigue intensity.Than higher, process is also very complicated, and can only carry out under the situation of electromagnetic interference not having to the conditional request of test for this method.
Also there is not a kind of simple equipment to realize accurate measurement in the prior art to fatigue strength.
Summary of the invention
Main purpose of the present invention is to provide a kind of fatigue detection device, to realize the measurement to the human-body fatigue degree.
Fatigue detection device provided by the invention comprises: a single-chip microcomputer, an ondoscope, a frequency generator, a keyboard; Wherein said keyboard produces the input that is used to increase frequency, reduces frequency; Described ondoscope is used to show the relevant data signal of the flicker frequency with frequency generator of described single-chip microcomputer generation; Described frequency generator glimmers according to described monolithic processor controlled frequency; Described single-chip microcomputer is connected respectively with described ondoscope, frequency generator, keyboard, and receives the input from keyboard, the flicker frequency of frequency generator is controlled, and sent the data signal relevant with flicker frequency to described ondoscope.
And described fatigue detection device also further comprises: a house dog, it is connected with described single-chip microcomputer, and is used for fatigue detection device is carried out forced resetting.
And described keyboard further also produces the input that is used to reset.
And described ondoscope can be a light emitting diode.
And described frequency generator can be a light emitting diode.
Fatigue detection device described in the present invention is simple to operate, cost is low, reliable operation.

Fig. 2 is the flow chart of the program moved in single-chip microcomputer shown in Figure 1.
Fig. 3 is the hardware circuit principle figure of the tester among the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described further, but are not limited to the particular content that present embodiment is narrated.
Fig. 1 is the system diagram of fatigue detection device embodiment one of the present invention.
As shown in Figure 1, in embodiments of the invention one, described fatigue detection device comprises: single-chip microcomputer 1, ondoscope 2, frequency generator 3, keyboard 4 and house dog 5.Wherein single-chip microcomputer 1 is connected respectively with ondoscope 2, frequency generator 3, keyboard 4 and house dog 5.
Wherein said keyboard 4 comprises: one increases frequency button, reduces frequency button, a SR and a power switch button.It makes single-chip microcomputer 1 produce control signal by the control of program by the input by increasing the frequency button and reducing the frequency button respectively, is that the frequency that frequency generator 3 produces increases or reduces.SR is used for after test is finished, and whole test instrunment is reset to power-up state.Power switch button is the on and off switch of whole test instrunment.
Ondoscope 2 is two light emitting diodes (LED), and the binary-coded decimal data signal that it is relevant with the flicker frequency of single-chip microcomputer 1 frequency generator 3 that produced and current is converted to seven sections font codes, and is presented on the LED with decimal scale.
Frequency generator 3 is constantly LED of flicker, and the frequency of its flicker is controlled by the software in the single-chip microcomputer.The tester just can see a display lamp that certain flicker frequency is arranged like this, and single-chip microcomputer can not differentiated the tester fatigue strength that frequency when glimmering is counted the tester.
Operation has the control sequence of this tester in the single-chip microcomputer 1.Fig. 2 is the flow chart of the program of operation in the single-chip microcomputer 1 shown in Figure 1.As shown in Figure 2, control sequence comprises following several steps.
Step S0: program start, bring into operation, when bringing into operation, program can preestablish the initial value of a flicker frequency.
After program begins, just enter in the circulation of step S1～S3.
Whether step S1: detecting has keyboard to press, if just carry out respectively that frequency adds one, frequency subtracts one and the operation that resets.
Step S2: if there is not keyboard to be pressed, then LED is according to current frequency values glimmer (initial value that initial flicker frequency is the flicker frequency among the step S0).
Step S3: frequency shows that the phase to current flicker frequency demonstration, is to be shown as 10 system numbers, to make things convenient for reading of tester here.
Above-mentioned flow process is arranged as seen, the input that visible single-chip microcomputer 1 receives from keyboard 4 is controlled the flicker frequency of frequency generator 3, and sends the data signal relevant with flicker frequency to described ondoscope 2, so that described ondoscope 2 shows flicker frequency.
When this tester is operated in when existing in the various interferential environment, the Single Chip Microcomputer (SCM) program in this tester can not occur running and flies and phenomenon such as deadlock, has also increased house dog 5 in this tester.Described house dog 5 can be single-chip microcomputer 1 forced resetting, to guarantee that tester still is operated in normal condition when being interfered.
Fig. 3 is the hardware circuit principle figure of tester, and it has disclosed the connection situation of the concrete electronic component of this instrument.Having adopted model in this schematic diagram is the single-chip microcomputer of 20C51.
The above only is the preferred embodiments of the present invention; be not to be used to limit protection scope of the present invention; the equivalent structure transformation that every utilization description of the present invention and accompanying drawing content are done, or be used in other relevant technical field directly, indirectly, include within protection scope of the present invention.
