Abstract

The invention discloses an anti-cheating high-precision intelligent digital weighing module and an anti-cheating method thereof. The digital weighing module comprises a signal amplification circuit, an AD converting circuit, a microprocessor, a temperature collecting circuit, a communication circuit, a power circuit and a surge prevention circuit. The anti-cheating method comprises the following steps that a data receiving terminal transmits a set of random numbers to the digital weighing module; the digital weighing module encrypts the received random numbers and actual measuring weight data through an encryption function f(x) to form encrypted messages; the digital weighing module transmits the encrypted messages to the data receiving terminal through a custom RS-485 communication protocol; the data receiving terminal receives the encrypted messages and then conducts encryption calculation through a decryption function to obtain the actual measuring weight data. The anti-cheating high-precision intelligent digital weighing module and the anti-cheating method thereof can effectively prevent the phenomenon that weight information is changed through signal interference, data tampering and other cheating methods, safety and reliability are achieved, the weight information is not likely to be tempered or stolen, and the reliability of data transmission is improved.

Description

technical field [0001] The invention relates to a weighing sensor, in particular to an anti-cheating high-precision intelligent digital weighing module and an anti-cheating method, belonging to the technical field of weight measurement. Background technique [0002] With the development of industrial control systems towards digitization and intelligence, digital weighing sensors have been developed and widely used in recent years. The digital load cell is connected to the digital weighing module after the elastic element is patched, cured, post-cured and wired to form a bridge, so that the load cell outputs a formatted and regular signal, and can realize long-distance transmission. Stability, safety, and reliability are the most concerned issues for users. However, some cheating devices have been found in some instruments and communication lines, indicating that the current digital weighing module transmission protocol used in digital weighing sensors has been cracked. In t...
