The invention provides an electronic police 
system detection reliability control method and 
system. The method comprises front-end equipment operation situation detection, 
data quality preliminary inspection, electronic police 
data quality inspection, risk data checking and 
risk assessment and 
data processing. A targeted 
data quality inspection method is adopted to automatically detect equipment offline, failure, network abnormity and other equipment operation abnormal situations and data null, 
timestamp error, data duplication and wrong data. Meanwhile, the risk of electronic police 
system detection and checking data is assessed according to equipment detection recognition rate, effective rate, illegal rate and other system data quality indicator detection situations and the illegal data artificial checking reliability detection result so that automatic inspection of the risk, the abnormal data and the equipment can be realized, the control requirements of 
traffic management personnel for the offsite law 
enforcement system data quality can be met, and law 
enforcement data reliability and effectiveness can be guaranteed.
