As shown in Figure 2, above-mentioned steps S5 can realize further in the following ways:
Step S51: reset register mark position, to discharge the latch to cumulative number, performs step S52 afterwards.
Step S52: judge whether register mark position is zero, in this way, then end step S5; As no, then perform step S53.
Whether step S53: judge during the speed of a motor vehicle is greater than described preset vehicle speed limit value, continue the second Preset Time and do not receive described tire pressure, in this way, then perform step S54; As no, then perform step S52.
Step S54: cumulative number is added 1, and by register mark position 1, to latch cumulative number, forbid repeatedly revising cumulative number after one-shot, perform step S52 afterwards.
