There are a lot of common cheating weighing methods in truck scales. Incomplete weighing or simultaneous weighing of multiple vehicles is for achieving the purpose of increasing or reducing the net weight of goods. Replacement of goods varieties in loading or unloading is for making the price difference between different varieties of goods. For mineral products, this method is much easier to use. Goods are taken by the way of pretending to be customers. For large mineral products, the loss of several trucks of goods may be never known if the information communication between consignee and consigner is not smooth or the management is far from being strict. Tares of truck scales are cheated. For example, heavy things may be secretly added to truck scales before the weighing of tare, but are abandoned after the weighing of tare, for the purpose of reducing the net weights of goods. License plate number is secretly exchanged. For example, two truck scales with different license plate numbers and tare are exchanged for loading the goods of different prices, or an empty truck is quit. A remote control device is directly added to the sensors of truck scales, making weighing standard changed. Internal and external collusions of truck scale management departments and customers make the weights of goods reduced or increased. Goods are replaced with inferior counterparts. In order to put an end to the above cheating, it is urgent for electronic truck scales to be improved from simple weighing functions to a weighing anti-cheating system with comprehensive control functions, sound anti-cheating means and fluent information communication solution. Seen from the actual cases, weighing system without comprehensive anti-cheating measures becomes the focus of criminal offense objects, thus giving rise to huge economic losses for enterprises. Anyway, a top priority is necessarily given to various anti-cheating techniques for preventing possibilities of cheating in truck scales.
