according to the first light control signal, a driving signal with a duty ratio of 1 is sent to the indicator light, so that the indicator light is kept in a normally-on state; according to the second light control signal, a driving signal with a duty ratio of 50% is sent to the indicator light, so that the indicator light is subjected to flickering illumination at 1/2 second intervals; according to the third light control signal, a driving signal with a duty ratio of 33% is sent to the indicator light, so that the indicator light is subjected to flickering illumination at 1/3 second intervals; according to the fourth light control signal, a driving signal with a duty ratio of 17% is sent to the indicator light, so that the indicator light is subjected to flickering illumination at 1/6 second intervals; and the number of the first and second groups,
the data access adjusting module is configured to automatically adjust the data access sequence between each terminal and the internet of things platform according to the priority level of the transmission sequence, and specifically includes:
and according to the sequence of the first priority order, the second priority order, the third priority order and the fourth priority order, automatically performing data access on the corresponding terminal and the Internet of things platform in sequence.
