Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, the process flow diagram of the computing method of service time that are software of the present invention in system.This method comprises that zero-time value and accumulated time value that software is used are stored in the flash memories of this system; Whether detection software is mounted or starts; Write down time value and amended time value before this system time is revised, and the zero-time value in this flash memories changed to time value before this system time is revised, the difference that this accumulated time value changes to time value and the zero-time value in the flash memories before system time is revised again with current accumulated time value with; Through cycle time, upgrade the accumulated time value that this software uses; Whether overtime limits to detect total accumulated software time; Restriction is taked in use in system to this software.
The concrete steps of this software computing method of service time in system are as follows:
Step 101: zero-time T0 and accumulated time T1 that target software uses are set, and this zero-time T0 and this accumulated time T1 are stored in the flash memories (Flash) of this system.Zero-time (absolute physical time) when this zero-time T0 is used for record object software startup (or installation), the accumulated time that target software used when T1 was used for recording user change system time.The initial value of this zero-time T0 and accumulated time T1 is 0.This flash memories is preferably NOR type flash memories.
Step 102: judge whether target software is mounted or starts,, then withdraw from this calculation procedure,, then enter step 103 if target software is mounted or starts if target software is not mounted or starts.
Step 103: this zero-time T0 is set to the time that this target software is installed or started, and the zero-time T0 that this is reset is stored in the flash memories of this system.
Step 104: judge whether system time is modified,, then enter step 106,, then enter step 105 if system time is modified if system time is not modified.
Step 105: write down time R0 and amended time R1 before this system time is revised, and the zero-time T0 in this flash memories is set to R1, accumulated time T1 is set to R0-T0+T1.
Step 106: at regular intervals the cycle, for example 1 hour or 1 day, the total cumulative time Tt after the calculating target software is brought into use supposed that current system time is TC, then total cumulative time Tt=TC-T0+T1.
Step 107: judge that whether overtime limits total accumulated time Tt, if not, then re-executes step 106, if then enter step 108.
Step 108: the software that the user uses is taked restriction, for example stop using or pay the fees again, and T0 is made as the current time of system, T1 is put 0 and deposit in this flash memories.
Compared with prior art, in the software of the present invention computing method of service time, before the register system time change and after changing time R0 and R1, and added up the service time of this software, thereby prevent the inaccuracy of the computing time that the user's modification system time brings.Therefore, the computing method of software of the present invention service time are more accurate, can prevent that the user from changing total accumulated time by revising system time, thereby reach the purpose of this software of protection.The computing method of software of the present invention service time are utilized the total accumulated time of Time Calculation of system itself, avoid using the network time server method for updating, owing to do not need to connect the networking, cost is lower.The computing method of software of the present invention service time can also can be used on PC so that be used in portable terminal, promptly can be used for the period of time for approval of software for calculation, also can be used for according to carrying out corresponding charge operation service time.
