Survey result；In this way, when structural damage occurs in electronic scale or is reequiped without authorization by trade company, real time measure coefficient and calibration metering system
Count existing difference can effecting reaction in exception monitoring result, thus by obtain exception monitoring result effectively realize to electricity
The monitoring that son claims, can find the abnormal conditions of electronic scale in time.It should be noted that for calculating calibration stoichiometric coefficient and reality
When stoichiometric coefficient calibration weighing AD value, allowance for bark zero-bit AD value, in real time weighing AD value be electronic scale weight conversion module output
Data, this is the content of the prior art, and it is not described here in detail.
Specifically, in the present embodiment, to electronic scale carry out calibration obtain calibration stoichiometric coefficient can be when leaving the factory into
Rower is fixed, that is to say, that just obtains calibration stoichiometric coefficient in the factory calibration of electronic scale and records in the database.In this way, mark
Devise a stratagem coefficient of discharge is to can effectively ensure that its accuracy to be supplied to trade company predetermined.As shown in Fig. 2, electronic scale into
When row factory mark timing acquisition devise a stratagem coefficient of discharge, Zero positioning can be first passed through got by electronic scale and allowance for bark zero-bit AD value, led to
It crosses and sets certain calibration weight, arbitrary point calibration is carried out in the case where known calibration weight and obtains calibration weighing AD value, when
So calibration weight can be known arbitrary value, then be weighed according to the following formula by allowancing for bark zero-bit AD, calibration weight and calibration
AD value, which calculates, obtains calibration stoichiometric coefficient: calibration stoichiometric coefficient=(calibration weighing AD value-allowance for bark zero-bit AD value)/calibration weight；

Scale monitoring method after getting exception monitoring result timely and effectively by exception monitoring result be supplied to electronic scale go out manufacturer and/
Or regulatory bodies, it can effectively facilitate electronic scale to go out manufacturer and/or regulatory bodies and effective prison is made to the service condition of electronic scale
It surveys, is conducive to the timely investigation to cheating.
In a further embodiment, in the exception for comparing the real time measure coefficient and calibration stoichiometric coefficient acquisition electronic scale
It can also include when judging that the occurrence law of exception monitoring result meets default rule, generating abnormal conditions after monitoring result
Information.Specifically, it is contemplated that cause electronic scale by under refitted vehicles, structural damage and normal external cause error condition, electronics
The rule for weighing out existing exception monitoring result is different, therefore can set default rule, when judging advising for exception monitoring result
When rule meets default rule, corresponding abnormal conditions information is generated；So as to more rapidly effectively to the operation feelings of electronic scale
Condition is monitored, for example, the abnormal conditions information may include structural damage, refitted vehicles and normal external cause error etc., when
The occurrence law of the exception monitoring result meets default rule 1, is judged as normal external cause error, when the exception monitoring result
Occurrence law meet default rule 2, be judged as refitted vehicles and/or structural damage；It specifically, described default regular 1 can be with
To occur the frequency of early warning in exception monitoring result lower than 1/A times, wherein A can be according to the precision or anti-interference feelings of electronic scale
The setting such as condition, for example, 10,000, i.e., when having early warning in the exception monitoring result for judging only to monitor in rare cases,
It is considered caused by error caused by normal external cause, electronic scale itself is in normal condition；Described default regular 2 can be abnormal prison
It surveys in result and continuous early warning occurs, i.e., each collected at this time real time measure coefficient occurs with calibration stoichiometric coefficient larger
Deviation, and being never interrupted, it is believed that electronic scale there are refitted vehicles or structural damage, can by go out manufacturer carry out recovery processing or
Person is handled by regulatory bodies；Certainly, suitable for different trade company's refitted vehicles behaviors, specific default rule can also be set
Rule, to realize effective judgement to different refitted vehicles behaviors.
