加油机作为机动车添加燃油的计量器具,是民生计量的重要组成部分,其准确与否越来越受到人们的关注。如何防范和查处加油机计量作弊行为,是我们需要研究突破的重要课题。工作原理及作弊原理2006年9月8日以前出厂的加油机,未含有计量防欺骗功能,称为普通加油机。普通加油机没有对加油机油量数据生成的正确性进行有效的监控,现在社会上不法分子主要针对普通加油机进行计量作弊。《燃油加油机检定规程》JJG443-2006规定,2006年9月8日后出厂的加油机必须具有防欺骗功能,称为防作弊加油机。由于防作弊加油机的防作弊功能仅限于对流量信号发生以后的油量数据的监控,故不能有效防止不法分子利用加油机的机械部分在流量信号发生以前进行的计量作弊违法行为。同时,如果防作弊加油机未进行初始化,编码嚣与监控微处理的相互验证功能即不能发生作用,防作弊加油机则不具备防作弊功能。
Tanker as a vehicle to add fuel metering equipment, livelihood measurement is an important part of its accuracy or not more and more people’s attention. How to prevent and investigate the measurement cheating tanker behavior is an important issue we need to study the breakthrough. Working principle and cheating principle Before September 8, 2006 the factory before the tanker, does not contain the measure of anti-cheat function, known as ordinary tanker. Ordinary tanker did not carry out effective monitoring of the correctness of tanker data generation. At present, lawless elements in the community are mainly aimed at measuring and cheating ordinary tanker. “Fuel tanker test procedures” JJG443-2006 provides that after September 8, 2006 factory tanker must have anti-cheat function, known as anti-cheating tanker. Anti-cheating tanker anti-cheat function is limited to the traffic signal after the oil volume data monitoring, it can not effectively prevent criminals to use the mechanical part of the tanker in the traffic signal before the measurement cheating violations. At the same time, if the anti-cheating dispenser is not initialized, the mutual authentication function between the codec and the monitoring micro-processing can not work, and the anti-cheating dispenser does not have the anti-cheating function.
