Anti-cheating device and detection method of weighing system based on digital sensor

Abstract

The invention discloses an anti-cheating device for a weighing system based on a digital sensor, comprising a digital sensor installed in the weighing system, characterized in that the digital sensor comprises a strain-type electric bridge, and the power supply terminal of the strain-type electric bridge The switch is connected to the power interface of the digital sensor, the output end of the strain-type bridge is connected to the processor unit through the AD conversion module, and the processor unit is also connected to the control end of the switch. A current detection unit between the digital sensor power supply interface and the sensor power supply, the output end of the current detection unit is connected with the processor unit. The utility model makes the digital sensor enter the dormant state through commands, reduces the basic current of the system, and facilitates the detection of the current increased due to the installation of the cheating device. The invention has the advantages of simple structure, good effect of preventing cheating by the remote control, and is not easy to misjudge and miss the judgment.

Description

technical field [0001] The invention relates to the field of anti-cheating of a weighing system, in particular to an anti-cheating device and a detection method of a weighing system based on a digital sensor. Background technique [0002] The method of remote control cheating is to add a wireless receiving device and signal superimposer to the weighing system, and send cheating commands through the remote controller outside. After receiving the command, the receiving device controls the signal superimposing device to work and change the weighing data to achieve cheating. the goal of. [0003] The current anti-cheating method is to judge whether there is a cheating remote controller working by receiving and analyzing the wireless signal near the weighing device, and if found, it will alarm and other processing. The method of receiving and analyzing wireless signals to detect cheating remote controllers is mainly judged by analyzing the existing wireless communication protoco...

AI Technical Summary

Problems solved by technology

The method of receiving and analyzing wireless signals to detect cheating remote controls is mainly based on the analysis of existing remote control wireless communication protocols, which is easy to misjudgment, and at the same time cannot detect remote controls with unknown frequency bands and unknown protocols
