Please refer to Fig. 3, flash driving circuit is formed primarily of a single-chip microcomputer U1, and single-chip microcomputer U1 frequency is provided by the crystal oscillating circuit of 4MHz crystal oscillator.When the concentrator marker 500 shown in Fig. 3 is in steel drum (storage mark railway carriage or compartment), outward, automatic switch S1, hand switch S2 are in off-state, and the input of single-chip microcomputer U1 no-voltage does not work.When concentrator marker 500 enters steel drum, hand switch S2 disconnects, automatic switch S1 closes, the power pins 14 of single-chip microcomputer U1 obtains 6V operating voltage, the reset pin 4 of single-chip microcomputer U1 is in high level and does not reset, the status pin 6 of single-chip microcomputer U1 has high level to input, and judges the holding state of laggard inlet identity device 500 through single-chip microcomputer U1.The now discharging current < 100uA of battery, if be placed in steel drum always, can discharge 18000 hours, meets the needs being placed on steel drum inside for a long time.Sampling delay circuit 400 in circuit, keeps sampled signal, and ensure that the moment can not caused due to external causes such as vibrations disconnects and single-chip microcomputer U1 is judged by accident, sampling hold period is T=R*C.When concentrator marker 500 from steel drum out, automatic switch S1 is by being closed into disconnection, status pin 6 voltage reduces, after single-chip microcomputer U1 judges, concentrator marker 500 enters normal operating conditions, single-chip microcomputer U1 pulse-width modulation output pin 17 output pulse width modulation signal controls LED module 100 earth terminal compartment of terrain ground connection or unsettled to controlling ground unit 300, makes LED module 100 realize flicker.When holding state, voltage output pin 18 output voltage of single-chip microcomputer U1 makes switch element 200, i.e. switching tube Q1 and switching tube Q2, and such single-chip microcomputer U1 just obtains lasting operating voltage, can not quit work because automatic switch S1 disconnects.Also ensure in programming simultaneously that the glittering concentrator marker 500 of the state of automatic switch S1 to normally work is without control action.When concentrator marker 500 needs to use in test or other environment beyond steel drum, closed by hand switch S2, the power pins 14 of single-chip microcomputer U1 obtains 6V operating voltage, and single-chip microcomputer U1 reset pin 4 is in high level and does not reset.The judgement pin 13 of single-chip microcomputer U1 has high level to input, then voltage output pin 18 not output voltage, and switch element 200 can not conducting.After single-chip microcomputer U1 judges, enter test mode, single-chip microcomputer U1 pulse-width modulation output pin 17 output pulse width modulation signal, make LED module 100 realize flicker.As disconnection hand switch S2, concentrator marker 500 quits work automatically.If concentrator marker 500 normal glittering time to close light fixture by hand, as long as press hand switch S2, concentrator marker 500 just can cut out.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
