The requirement of the communication access net optical transceiver module to realizing photoelectricity, electro-optic conversion is more and more higher, and the test of optical transceiver module is also got over
Come the most complicated.Mostly there is the problems such as testing cost is high, testing efficiency is low, test system is loose.
In optical module industry, the most whether the firmware to optical module is lost and is detected, and is all at optical module
Client terminal test or normal use in find that optical module cannot normally work, and I2C bus access optical mode can not be passed through
The slave addresses of block, reads internal information, it is judged that optical module lost efficacy, and then by client feedback to optical module manufacturer, by light
The manufacturer of module carries out maintenance analysis, could find that the firmware of optical module is lost.And said method can not detect in advance
The situations such as firmware loss.Optical module firmware is divided into the a0/a2 table of protocol requirement, comprises monitoring and company-information, and this is basic,
Followed by some regulation parameters of module oneself itself store.Major part optical module is by microprocessor, laser drive circuit, amplitude limit
Amplifying circuit forms.And the most commercially available microprocessor (MCU) is various in style, various, most of Micro-processor MCVs are all
Having defect BUG of self, unessential BUG that depositor can be caused to access, depositor cannot be rewritten, and I2C sequential is abnormal,
Great BUG can cause microprocessor (MCU) I2C to be not responding to, even the situation such as firmware loss.The wherein firmware of microprocessor
Loss situation occurs in the model that current optical module high-volume uses, and repeatedly plugs at optical module or repeats to power on
During, it may appear that the microprocessor firmware of optical module is lost, and firmware loss can directly result in optical module and cannot work, thus lead
Cause the paralysis of corresponding switch, service disconnection, and this phenomenon once occurs, then illustrate that the microprocessor that this optical module uses exists
Functional major defect BUG, should consider carefully during type selecting, need to consider that other schemes are replaced if having used.It is therefore desirable to
Development and producing the stage in enormous quantities, loses test to the firmware of microprocessor and is extremely necessary.
Summary of the invention
The present invention is to provide a kind of simple in construction, easy to detect, it is possible to avoid losing because of firmware causing optical module to lose efficacy
The method of testing that detection optical module firmware is lost.
The technical solution adopted for the present invention to solve the technical problems is, a kind of test side detecting optical module firmware loss
Method, including: detect the test printing board PCB of optical module to be measured, it is characterised in that: set on test printing board PCB
Put the electrical connection stand by lamp of Programmable Logic Device, buzzer and energy supply control module, and compiling in Programmable Logic Device
The embedded computing chip of journey logical device (PLD) arranges optical module firmware and loses test software；When detecting optical module to be measured,
Optical module to be measured is connected electrically between Programmable Logic Device and energy supply control module；Then test is lost at optical module firmware soft
Part arranges power on number of times and each power-on time of repeating of tested optical module, test printing board PCB power on number of times and
Power-on time is arranged by host computer, then powers on optical module, and the optical module firmware in Programmable Logic Device loses test
The firmware condition of software inquiry optical module the most also exists, if firmware is lost, then Programmable Logic Device conducting stand by lamp Chang Liang, opens
Dynamic buzzer warning, simultaneously by tested optical module power-off；If firmware condition is normal, then controls energy supply control module and will not give optical mode
Block is powered, and whether the number of times that judges to power on meets the number of times setting value that powers on, and powers on number of times if meeting setting optical module, then exits
Program；If powering on, number of times is not reaching to setting value, then continue to power on optical module, proceed the cyclic part of this program.
The present invention has the advantages that.
Simple in construction.The hardware components of the present invention uses and electrically connects FPGA electricity on test printing board PCB
The stand by lamp on road, buzzer and energy supply control module, device is few, simple in construction.
Easy to detect.When the present invention detects optical module to be measured, only optical module to be measured is connected electrically in Programmable Logic Device
And between energy supply control module, by number of times and the power-on time of powering on accordingly, detection can be completed.It is especially suitable for development
Whether the firmware of test of last shipment stage optical module aborning has the situation of loss.Therefore, in development, need
When the microprocessor (MCU) of type selecting is carried out reliability testing, can be carried out by this test printing board PCB, carry out many
Secondary upper electrical testing, gets rid of and has the situation that there is firmware loss.And this test printing board PCB can aborning
Last operation is tested, and can expand checking quantity and proving time, observe the batch testing situation of this microprocessor.
Decrease loss of data and improve maintainability.Avoid losing because of firmware causing optical module to lose efficacy.

Survey the test printing board PCB of optical module to be measured.Test printing board PCB is provided with electrical connection Programmable Logic Device
Stand by lamp, buzzer and energy supply control module, when detecting optical module to be measured, optical module to be measured be connected electrically in FPGA electricity
Between road and energy supply control module.The operation principle of this method of testing is as follows, and Programmable Logic Device controllable power controls mould
Block, the operation that controls to repeat tested optical module to power on/off, power on number of times and power-on time, and can detect tested optical module
Firmware condition, the firmware of tested optical module be detected occur in that loss, Programmable Logic Device make stand by lamp highlighted and
Make buzzer warning.Otherwise, stand by lamp keeps often going out, and buzzer does not pipes.The test printed circuit board that in figure, rectangle frame is
PCB。
Refering to Fig. 2.The Programmable Logic Device working method of test printing board PCB will use following software algorithm real
Existing, first, arrange tested optical module in optical module firmware loses test software repeats power on number of times and each power-on time,
Test printing board PCB power on number of times and power-on time is arranged by host computer, then optical module is powered on, now can compile
Optical module firmware loss test software in journey logic circuit can be inquired about the firmware condition of optical module and the most also exist, if firmware is lost
Lose, then Programmable Logic Device makes stand by lamp Chang Liang, and makes buzzer warning, simultaneously by tested optical module power-off；Gu if
Part state is normal, then controlling energy supply control module will not power to optical module, and whether the number of times that judges to power on meets setting value, if
Meet setting optical module to power on number of times, then quit a program；If powering on, number of times is not reaching to setting value, then continue on optical module
Electricity, proceeds the cyclic part of this program.
The present embodiment to use as a example by the microprocessor SFP optical module as C8051F336, this detection device in engineering
Apply as follows.
Using the SFP optical module of C8051F336, be I2C access interface, C8051F336 is the core core of SFP optical module
