实施例一
请参阅图1，其显示了本发明实施例提供的一种电子秤监测方法的流程图。如图1所示，该电子称监测方法包括以下步骤：
对电子称进行标定获取标定计量系数；
获取电子称在称重时的实时计量系数；
对比所述实时计量系数和标定计量系数获取电子称的异常监测结果；
其中，所述标定计量系数=（标定称重AD值-除皮零位AD值）/标定重量；实时计量系数=（实时称重AD值-除皮零位AD值）/实时重量。
本实施例提供的电子称监测方法通过获取电子秤的标定计量系数，而在电子称用于称重时再获取实时计量系数并且用于与标定计量系数的比较，从而获取电子称的异常监测结果；这样，当电子称出现结构损伤或者被商户擅自改装时，实时计量系数与标定计量系数出现的差异能够有效反应在异常监测结果中，从而通过获取异常监测结果有效实现对电子称的监测，能够及时发现电子称的异常情况。需要说明的是，用于计算标定计量系数和实时计量系数的标定称重AD值、除皮零位AD值、实时称重AD值为电子秤重量转换模块的输出数据，此为现有技术的内容，在此不做详述。
具体地，在本实施例中，对电子称进行标定获取标定计量系数可以是在出厂时进行标定，也就是说在电子秤的出厂标定时就获取标定计量系数并记录在数据库中。这样，标定计量系数是在提供给商户之前确定的，能够有效保证其准确性。如图2所示，在电子称进行出厂标定时获取定计量系数时，可以先通过零位标定由电子秤获取到除皮零位AD值，通过设定一定的标定重量，在已知标定重量的情况下进行任意点标定获取标定称重AD值，当然标定重量可以为已知的任意值，然后根据以下公式由除皮零位AD、标定重量和标定称重AD值计算获得标定计量系数：标定计量系数=（标定称重AD值-除皮零位AD值）/标定重量；之后将标定计量系数传输至数据库由数据库记录。
在另外的实施例中，对电子称进行标定获取标定计量系数可以是在强检时进行标定，即电子称在出厂后提供给商户时，由监管机关对电子称进行强检时进行标定，并获取标定计量系数。当然，在另外的实施例中，对电子称进行标定获取标定计量系数也可以是在出厂时进行标定和在强检时进行标定，即在出厂时已经进行标定的情况下，在强检时再进行标定实现复核，此时以强检时确定的标定计量系数为准，从而有效保证标定计量系数的准确性。
具体地，在本实施例中，如图3所示，获取电子称在称重时的实时计量系数可以通过在实际称重重量下获取实时称重AD值，然后将实时重量、除皮零位AD值和实时称重AD值传输至数据库，数据库根据以下公式计算实时计量系数：实时计量系数=（实时称重AD值-除皮零位AD值）/实时重量，需要说明的是，这里的实时重量是指电子称的显示重量。需要说明的是，为了保证实时称重AD值的准确性，还包括电子称的置零计算，即获取空称时的实时AD值作为空称AD值，并计算空称AD值与除皮零位AD值的差值，在称重时获取到的实时AD值需要减去所述差值作为实时称重AD值。需要说明的是，由于除皮零位AD值在标定时通过零位标定确定了，因此在称重时根据之前确定的除皮零位AD值进行计算即可，其中除皮零位AD值存储于电子称中。
更具体地，在本实施例中，获取电子称在称重时的实时计量系数可以是对电子称每一次称重时的实时计量系数都进行获取，这样电子称每一次称重是否出现异常都能够得到记录，并可以用于与标定计量系数进行对比，从而实现对电子称的每一次称重进行监测，有效保证了对电子称进行监测的实时有效性。
在另外的实施例中，考虑到电子称在使用过程中称重的频繁程度，也可以是按照预设频率来获取电子称的实时计量系数，例如可以是每隔N次称重获取一次实时计量系数，其中N可以为3或者5等，当然N的取值可以根据实际需要进行设定，例如根据电子称的使用频率按照百分比来确定，这样可以减少传输到数据库中的实时计量系数的数据量，保证交易顺畅；当然适用于具体的应用情况，也可以是每隔N次称重获取多次实时计量系数。在另外的实施例中，也可以是按照预设时间来获取电子称的实时计量系数，例如可以是每X小时获取一次实时计量系数，其中可以是每天或者每一小时获取一次实时计量系数等，当然也可以是每X小时获取多个实时计量系数；当然，在预设时间内未发生称重作业则获取不到对应的实时计量系数，而如果在预设时间内发生多次称重作业，也仅获取一次称重系数，这样可以有效保证对电子称的监测的实效性和及时性。当然，在另外的实施例中，也可以是按照预设频率和预设时间结合来获取电子称的实时计量系数，例如可以是每X小时内每隔N次称重获取一次实时计量系数。
更具体地，在本实施例中，所述对比所述实时计量系数和标定计量系数获取电子称的异常监测结果为通过计算所述实时计量系数和标定计量系数的比值R获取异常监测结果；所述异常监测结果包括正常情况、轻度预警、中度预警和重度预警，其中，当实时计量系数与标定计量系数的比值R满足95%≦R≦100%时，判断为正常情况，当所述比值R满足为90%≦R＜95%时，判断为轻度预警；当所述比值R满足为80%≦R＜90%时，判断为中度预警；当所述比值R满足R＜80%时，判断为重度预警。这样，通过计算所述实时计量系数和标定计量系数的比值能够有效反应出电子称的称重显示重量与称重实际重量的的偏离情况，继而根据比值的不同对异常监测结果进行判断，可以有效反应电子称的异常的严重程度，有利于出厂商或者监管机关进行判断和处理。
具体地，在本实施例中，在所述对电子称进行标定获取标定计量系数之前还包括将电子称在数据库中注册，所述数据库为云平台数据库，具体地，将电子称在数据库中注册可以是使得电子称在数据库中具有唯一标示，优选地，还可以是同时绑定使用信息如商户、摊位等信息；例如可以是使用电子称出厂编号及序列号将电子称注册到数据库，并将电子秤的使用商户、摊位等信息输入到数据库中与出厂编号及序列号对应，这样，获得的电子称的异常监测结果可以迅速对应到具体的每一个电子称及其使用信息上，从而能够更好地对电子称实现监测。
进一步地，本实施例提供的电子称监测方法还包括将异常监测结果传输给监管平台。所述监管平台可以将异常监测结果反映给电子称出厂商和/或监管机关；例如，可以是由电子称出厂商和/或监管机关登陆到监管平台来获取到异常监测结果，也可以是由监管平台发送异常监测结果信息到电子称出厂商和/或监管机关，这样，本实施例中提供的电子秤监测方法在获取到异常监测结果后及时有效的将异常监测结果提供给电子称出厂商和/或监管机关，可以有效方便电子称出厂商和/或监管机关对电子称的使用情况作出有效监测，有利于对作弊行为的及时查处。
在另外的实施例中，在对比所述实时计量系数和标定计量系数获取电子称的异常监测结果之后，还可以包括判断异常监测结果的出现规律满足预设规律时，生成异常情况信息。具体地，考虑到导致电子秤遭到非法改装、结构损伤以及正常外因误差情况下，电子秤出现异常监测结果的规律不同，因此可以设定预设规律，当判断异常监测结果的出现规律满足预设规律时，生成对应的异常情况信息；从而能够更加迅速有效对电子秤的运行情况进行监测，例如，所述异常情况信息可以包括结构损伤、非法改装和正常外因误差等，当所述异常监测结果的出现规律满足预设规律1，判断为正常外因误差，当所述异常监测结果的出现规律满足预设规律2，判断为非法改装和/或结构损伤；具体地，所述预设规律1可以为异常监测结果中出现预警的频率低于1/A次，其中A可以根据电子称的精度或者抗干扰情况等设定，例如为一万，即当判断出仅在极少数情况下监测到的异常监测结果中有预警时，认为是正常外因导致的误差所致，电子秤本身处于正常状态；所述预设规律2可以为异常监测结果中出现连续预警，即此时采集到的每一个实时计量系数均与标定计量系数出现较大偏差，且从未间断，认为电子称存在非法改装或者结构损伤，可以由出厂商进行回收处理或者由监管机关进行处理；当然，适用于不同的商户非法改装行为，还可以设定具体的预设规律，从而实现对不同非法改装行为的有效判断。

本实施例提供的电子称的监测系统通过由布置于电子称中的获取单元来获取标定称重AD值、除皮零位AD值、标定重量、实时称重AD值和实时重量，可以由布置于电子称中的计算单元计算得到标定计量系数，通过发送单元可以将标定计量系数、实时称重AD值、除皮零位AD值和实时重量发送至数据库，经数据库中的计算单元进行计算获得实时计量系统并通过对比单元进行对比获取异常监测结果；这样，当电子称出现结构异常或者被商户擅自改装时，实时计量系数与标定计量系数出现的差异能够有效反应在异常监测结果中，从而通过获取异常监测结果有效实现对电子称的监测，能够及时发现电子称的异常情况。
具体地，在本实施例中，所述获取单元可以是配置为在出厂标定时获取用于计算标定计量系数的标定称重AD值、除皮零位AD值和标定重量，也可以是配置在强检标定时进行获取，在获取到标定称重AD值、除皮零位AD值和标定重量后，由布置于电子称中的计算单元进行计算获得标定计量系数后将该数据发送至数据库进行计算和对比。

更具体地，在本实施例中，所述对比单元通过对比所述实时计量系数和标定计量系数的比值R获取异常监测结果；更具体地，所述异常监测结果包括正常情况、轻度预警、中度预警和重度预警，其中，当所述对比单元计算得到实时计量系数与标定计量系数的比值为95%-100%时，判断为正常情况，当所述比值R满足为90%≦R＜95%时，判断为轻度预警；当所述比值R满足为80%≦R＜90%时，判断为中度预警；当所述比值R满足R＜80%时，判断为重度预警。这样，通过对比单元计算所述实时计量系数和标定计量系数的比值能够有效反应出电子称的称重显示重量与称重实际重量的的偏离情况，继而根据比值的不同对异常监测结果进行判断，可以有效反应电子称的异常的严重程度，有利于出厂商或者监管机关进行判断和工作。
进一步地，本实施例提供的电子称监测系统还包括传输单元，用于将异常监测结果传输给监管平台，所述监管平台配置为将异常监测结果反映给电子称出厂商和/或监管机关；具体地，可以是由电子称出厂商和/或监管机关登陆到监管平台来获取到异常监测结果，也可以是由监管平台发送异常监测结果信息到电子称出厂商和/或监管机关，这样，本实施例中提供的电子秤监测系统在获取到异常监测结果后及时有效通过传输单元将异常监测结果提供给电子称出厂商和/或监管机关，可以有效方便电子称出厂商和/或监管机关对电子称的使用情况作出有效监测，有利于对作弊行为的及时查处。
进一步地，在另外的实施例中，电子称监测系统还可以包括分析单元，用于判断异常监测结果的出现规律满足预设规律时，生成异常情况信息。具体地，考虑到导致电子秤遭到非法改装、结构损伤以及正常外因误差情况下，电子秤出现异常监测结果的规律不同，因此可以设定预设规律，利用分析单元判断异常监测结果的出现规律满足预设规律时，生成对应的异常情况信息；从而能够更加迅速有效对电子秤的运行情况进行监测
