Detailed analysis of remote cheating methods and countermeasures for electronic truck scales

Building materials "target=_blank> building materials, electricity and other industries, but cheating behavior came into being, seriously affecting fair trade settlement. I have done in the article "Electronic truck scale cheating and countermeasures" Corresponding analysis and presentation. However, in recent years, the phenomenon of cheating on the remote control is shocking. This paper further analyzes the electronic remote control cheating and explains the Jilin electronic crane scale.
statement of problem:
Let's first look at a form that is stated in a sample book of a well-known company in promoting its own anti-cheating products. Let us not consider it from a quantitative perspective, but the data presented is enough to shock us. This further illustrates how harmful the cheating of electronic weighing instruments is. In fact, many companies have far more weighing than the table below, and the current market price of goods is higher than the value in the table. The cheating weight may be much larger than 0.8 tons. !
Weighing materials:
The average number of pounds per day - the economic loss of each day of the year, the economic loss of the whole year, the cargo yard of the Korla Railway Station in Xinjiang, when the electronic truck scale is used for weighing, often causes the truck to increase the amount of money and fraud, and the Urumqi Railway Police has solved the case. The remote control device for criminal suspects has four buttons A, B, C and D, which respectively increase the weight by 0.5 tons, 1 ton, 1.5 tons and 2 tons. By installing the receiving device under the electronic truck scale in advance, the remote controller can control the weight displayed by the electronic truck scale within 150 meters, and achieve the purpose of fraudulently gaining money by fraudulent weight gain. A large steel mill in Zhejiang Province found that the remote control cable was installed on the load cell cable in the electronic truck scale, and the economic loss reached millions of yuan. Remote cheating of electronic scales has seriously affected fair trade settlement. It is bound to cause the legal metrology supervision departments, related enterprises and individuals to attach importance to Jilin electronic crane scales.
The status quo of electronic remote control cheating:
On the famous search engine website Baidu search keyword "**", the search results up to 679000 records, of which more than 90% of the information is the electronic remote control device in the use of electronic truck scale cheat information. At the same time, 1190 related pictures were searched, and most of the information directly responded to the remote control. Surprisingly, some people have already done it as a specialization, and have formed batches and scales. .
Weighing device:
Different types of electronic truck scale remote control cheats - a person who specializes in cheating technology has such a paragraph: With the popularity of the platform industry in mainland China, it will bring greater business opportunities to users, along with high-tech figures. With the advent of the weighbridge, the studio responded to the needs of the market, and successively launched digital ** devices such as the company, marking the studio's courage to solve the era of digital devices.

Third, the electronic truck scale remote control cheating prevention and countermeasures Through the above examples fully explain, whether the analog electronic truck scale or digital electronic truck scale has failed to escape the electronic remote control, almost all the mainstream in the market The products are also not spared. On the one hand, it is driven by interests, and on the other hand, it is due to the lag of technological development. Although the current information on the Internet is difficult to distinguish between true and false, from the perspective of a professional technician, you have to admit that the development of cheating technology is indeed very rapid. It is an excerpt from a person who specializes in the device to say such a passage, which deserves our deep thought! (The following is an excerpt from the author, but no changes have been made): I have been engaged in the installation and commissioning of the device for 6 years. I have a lot of experience in installation. Now there are many false advertisements on the market, saying that there is no need to install, direct remote control, then Prove that they are not professional personnel, or have never engaged in this industry at all, they are sending money first and then shipping, do you dare? Or you go to visit his demo, you have to do your hands and feet in advance, there is such a magic to let him come to my platform to try, 100,000, I have to.
The weighbridge is wired and shielded (you don't believe that you will open the line and you will see the shielded cable), there is no receiving module inside, what remote control is it used? If the interference with the magnetic field is ok, but it is only interference, it can not be counted as a remote control, because it can not be accurately displayed. If it is pure wireless, then the electrical equipment will not be messed up, and the bank teller machine can not be remotely controlled. How much does it cost? All right, what do you do with the remote scale?
I simply commented on their products. All the wireless remotes you saw on the Internet, what Japan, the United States, I said are deceptive, it does not exist. Why do I say this? First of all, we can't do it in principle. There are a lot of remote controls you've seen, such as TV, air conditioner, car, many, they all have a receiver inside, and then remote control with remote control, you see After I have not received anything, I can only operate it with a remote control?
The real device is to install the small body on the electronic circuit of the weighbridge. It is not the one that is not required to be installed on the market. Instead, it needs to connect a receiver with a size similar to a matchbox to the line of the weighbridge. And the very concealed signal receiver to achieve remote control is not achieved by changing the magnetic field.
From the above examples and the current situation, the electronic truck scale says that the installed remote control is smaller and smaller, and the concealment is getting stronger and stronger. At the same time, it has various internals, bus cables and D-type plugs. How to install it. In summary, there are two kinds of cheating behaviors. One is that the user of the electronic truck scale installation is unaware of it, and some criminals are driven by the interests of the illegal trucks. On the other hand, the electronic truck scale installation user deliberately installs. The purpose is to harm the victims in pursuit of greater interests. The latter generally appears in small private companies or individual behavior. Electronic truck scale cheating has a variety of characteristics, here only the prevention of remote control cheating analysis, other forms of cheating have been elaborated in the relevant papers, and will not be repeated here.
Preventing and containing remote control cheating will not seriously affect fair trade unless a multi-pronged approach is adopted. The first type of cheating behavior mentioned above is as follows: (1) It is recommended that enterprises use 24-hour video surveillance unattended electronic truck scales to enhance the irregular inspection of load cells, cables and junction boxes. Key parts such as sensors and junction boxes should be sealed to prevent people from opening and destroying. If an abnormality is found, report to the relevant department immediately. (2) It is recommended that the company conduct professional training on the electronic weighing instrument supervision department to understand and master the electronic weighing instrument. Working principle is conducive to targeted investigation. The second type of cheating behavior For the present, the author has not been able to think of effective prevention methods, but only to recommend the strengthening of the legal supervision department. For instrument manufacturers, the wiring of the instrument uses a very small waterproof air plug. In short, only multi-party linkage can effectively curb the electronic remote control device to chew the electronic truck scale. Avoid illegal elements installing remote control receivers inside the instrument or D-type joints. For the current digital electronic truck scale, the cheater mainly enlarges or reduces the sensor output internal code, or performs data tampering on the processor to the display part. Except for the internal and joint parts of the meter, the focus is on whether the remote sensor receiver is installed on the load cell output cable or bus. Although the electronic remote control receiver does not consume much power, it must steal the Jilin electronic crane scale from the system.
Multi-party linkage to cope with the cheating behavior of electronic remote control devices on electronic truck scales will inevitably lead to the proliferation of fraudulent practices. But fundamentally speaking, how to guarantee the technology and process of the product? Emphasis on encryption technology, the author has written about AES encryption technology; attaches importance to system power detection, technically eliminates electricity theft; increases the handling and warning of wireless signals in the system; (4) attaches importance to the packaging method and process of the instrument, and pays attention to the outlet part The design, if the cheater can not open the meter at all, can not install wireless receiving equipment in the narrow joint parts, will improve the system's anti-cheating ability. The above is limited to some of the author's views. More and better anti-cheating techniques require a large number of professional and technical personnel to jointly study and overcome. From the current point of view, digital technology is not as powerful as the anti-cheat ability in the original propaganda, but has become a tool for related companies to exclude dissidents and dominate the monopoly market share. I think this is not only a question that should be reflected by relevant enterprises, but also a question that the entire industry should reflect.
Although the digital electronic truck scale's anti-cheat ability is stronger than the analog weighing system, because the cheaters are driven by the interests, they have been focused or specialized in electronic remote control cheating technology to lead to the above content described in this article. Whether it is an analog electronic truck scale or a digital electronic truck scale, it has been successfully cheated for cheaters. Cheating technology is also developing. Anti-cheating technology can only effectively curb the cheating behavior if it is continuously developed and updated. It is gratifying that in recent years, China International Weighing Apparatus Exhibition has found that some companies have specialized in anti-cheating technology system design. With R&D, and mature products have been introduced.
Electronic truck scale remote control cheating has greatly affected the fair trade settlement, bringing huge losses to related companies and individuals, which will inevitably attract everyone's attention. To curb cheating, we need to cooperate with each other to resist. We hope that our colleagues in the scale manufacturing industry will actively participate in preventing cheating, abide by professional ethics, and escort fair trade.
