Abstract
A system using pulse counting for realizing the shutdown of mobile communication equipment is provided. Users send out a shutdown instruction to a central processing module through an operation module. After receiving the shutdown instruction, the central processing module continuously produces a regular pulse to a CPLD power control module which counts the regular pulse. When the CPLD power control module counts to a certain number of continuous pulses and the system is in the power condition, the CPLD power control module sends out a shutdown instruction to a main power module which stops supplying power to the system. The system using the pulse counting for realizing the shutdown of the mobile communication equipment can filter out uncontrollable conditions which are sent out by a CPU to avoid the wrong judgments of CPLD so as to realize the stable shutdown function of software.
