Below again based on above-described embodiment, introduce an application example of the present invention.
The object of application example of the present invention there are provided a kind of solution avoiding software frequently to read the software reading optical module information that optical module information causes CPU usage too high.Enforcement below in conjunction with accompanying drawing 3 pairs of technical schemes is described further:
Fig. 3 is the processing procedure reading optical module information in application example of the present invention.As shown in Figure 3, this processing procedure generally comprises following two parallel processes:
Process one:
Step 11: the optical module all to equipment carries out traversing operation, the presence situation of change of perceived light module.
Step 12: the information in place obtaining hardware optical module, obtain the information in place of optical module overall situation software register, whether both change by comparison presence simultaneously.If do not changed, then determine whether last optical module of equipment, if so, then carry out step 14, otherwise return step 12; If state changes, then carry out step 13.
Step 13: disposable acquisition optical module moves static information and stored in software global table, optical module like this be equipment last, then carry out step 14, otherwise returns step 12.
Step 14: all optical module traversal is complete, delay time T1, this time is less than the time that staff plugs optical module, is generally Millisecond, returns step 11.
Process two:
Step 15: the optical module all to equipment carries out traversing operation, for each optical module, performs step 16 ~ 19 below.
Step 16: judge the presence in optical module overall situation software register, if optical module off-line, then determining whether last optical module of equipment, is carry out step 110, otherwise returns step 16 and process next optical module; If optical module is online, then carry out step 17.Often execute an optical module, 1 is added to global variable;
Step 17: the multidate information obtaining optical module, such as: luminous power and bias current etc., and stored in overall software register.
Step 18: time delay T2 time.
Step 19: (if first time counting, be 0) counting from the global variable that last time preserves, if be the integral multiple of 5, then carry out step 110, otherwise returns step 16 and process next optical module; If be last optical module, global variable counting resets.
Step 110: delay time T3, returns step 15.
The method of the described reading optical module information of application example of the present invention is a kind of optical module information read method of comprehensive software simulation I2C clock, and while ensureing data real-time update, the reduction of maximum possible is to the occupancy of CPU.First the information type read will be needed in the method to be divided into static information and multidate information, and static information such as wavelength, manufacturer number, transmission range etc. determine the information that just no longer changes once optical module.Multidate information is as the information of the real-time change such as luminous power, bias current.For static information, when only plugging optical module when the information in place of optical module changes, just carry out the reading of optical module information.For multidate information, just read after optical module inserts always.For avoiding the optical module of disposable reading more, causing the instantaneous utilization factor of CPU too high, adopting each reading 5 optical modules, often run through an optical module release CPU, release duration is T2.Run through delay time T3 after 5 optical modules, then read follow-up 5 optical modules.The optical module information read is kept in global variable, calls display for upper layer module.
By the explanation of embodiment, should to the present invention for the technological means reaching predetermined object and take and effect be able to more deeply and concrete understanding, but appended diagram be only to provide with reference to and the use of explanation, be not used for being limited the present invention.
