Note to electronic truck scale:
As an accurate, convenient and fast weighing and measuring equipment, electronic truck scale is increasingly used in coal, metallurgy, building materials, stone, electric power, grain trade, logistics and other industries. But in many areas the use of electronic truck scale is weighed in the process of measuring the phenomenon of cheating, adopt various ways when vehicle measurement gross weight, tare weight checkers, causing hundreds of kg less, more than a few tons of measurement deviation, from illegal profit, not only brought huge economic losses to the enterprise, also disturb the social economic order. The following are the existing ways and preventive measures of truck scale cheating:
Directly on the truck scale sensor instrument equipped with the controls, change its weighing some illegal personnel at scale load sensor, junction box and instrument equipped with remote control device to control weight, this method of cheating is using measurement point no one watching the night or when it is not easy to be found, remove outdoor sensor to the signal lines, electronic equipment series. When the vehicle metering, the remote control of these electronic equipment, so as to send to the instrument signal impact, metering results can be large, small, to obtain illegal income. Because the design of these cheating devices of the personnel themselves on the electronic scale of the structure, principle is quite clear, so these devices are difficult to be found in the measurement process, so that the enterprise in the unwitting circumstances suffered great economic losses. Solution: the management personnel and the division weigher regularly check the sensor, junction box and meter of the loadometer, find abnormal stop using the truck scale immediately contact the metrological verification personnel; The most fundamental solution is to use digital sensors and digital weighing instruments. The biggest advantage of digital truck scale is super anti - interference and anti - cheating performance. The signal of the digital sensor USES encrypted digital transmission, only the unique decoding instrument can obtain data, the signal has not been decrypted before anyone can not steal and interference, thus other remote control device to obtain and modify the data, to ensure the safety of the output signal.
