Problems solved by technology

[0005] 3) Tampering with the weighing data on the display side or instrument side
[0006] 4) The owner or operator of the weighing system is also a cheater, keeping watch and stealing. In this case, the country needs to formulate relevant laws and regulations to regulate weighing behavior
[0012] To sum up, the various anti-cheating methods that have been proposed or exist can basically prevent one or several types of cheating to a certain extent, but cannot prevent the occurrence of cheating from the root.

Embodiment 1

[0083] Example 1: Application of Vehicle Scale Digital Weighing System

[0084] see Figure 5 , The vehicle scale digital weighing system is mainly composed of a scale body 3, 8 digital load cells 1, a communication cable 4 and a weighing instrument 2. Each digital load cell 1 includes an anti-cheating module 5 . This weighing system uses the bus communication protocol, chain network connection, no junction box. The scale body 3 is a weighing carrier. When the vehicle stops or slowly drives through the scale body 3, the weight of the vehicle and goods is directly loaded on the scale body 3. Eight digital weighing sensors 1 are installed in the scale body 3 to collect vehicle weight signals respectively. The initial analog weighing signal is converted by A / D and converted into a stable noise-free digital weighing signal after digital signal processing; The weighing signal enters the anti-cheating module 5 to determine whether the weighing signal contains a cheating signal. I...

Embodiment 2

[0105] Example 2: Application of Platform Scale Analog Weighing System

[0106] see Figure 8 , The platform scale weighing system is mainly composed of a scale body 3, 4 analog load cells 1, an analog junction box 6, a communication cable 4, an anti-cheating module 5 and a weighing instrument 2. The anti-cheating module 5 is embedded in the weighing instrument 2 . Four analog load cells 1 are physically installed in the scale body 3 to collect weight signals respectively. The analog junction box 6 summarizes the signals from the four analog load cells 1, and sends the summarized analog signals to the weighing instrument 2, and the weighing instrument 2 performs analog-to-digital conversion on the collected analog signals and converts them into digital signals , the digital signal is converted into a stable noise-free digital weighing signal after digital processing such as digital filtering; the weighing signal after digital signal processing enters the anti-cheating module...

Abstract

The invention discloses a weighing system and an anti-cheating method and equipment for the weighing system. The weighing system of the present invention includes a weighing terminal, at least one load cell coupled to the weighing terminal, and an anti-cheating module. The anti-cheating module includes: a reading sub-module for reading weight signals from at least one load cell; features The analysis submodule performs signal analysis on the weight signal to extract at least one feature in the change trend of the weight signal; the feature discrimination submodule determines whether at least one feature is abnormal, and determines whether there is cheating based on the judgment result of whether at least one feature is abnormal Behavior. Other embodiments are disclosed and claimed.

Description

technical field [0001] The invention relates to the weighing field, in particular to a weighing system and a cheating prevention method and device for the weighing system. Background technique [0002] In various weighing applications, cheating on the weighing system occurs from time to time. Illegal weighing and cheating have caused great economic losses to the society, enterprises and individuals, and also have a bad negative impact on the fair business environment. At present, there are mainly the following types of cheating methods for the weighing system: [0003] 1) Tampering or interfering with the output of the sensor's analog signal. After breaking open the sensor shell, the cheater connects the cheating device to the output signal line of the electrical signal of the load cell, and tampers with or interferes with the output of the analog signal of the sensor, so that the weight value displayed on the terminal is higher or lower than the actual weight value; The ...
