​On the cheating of floor scale

On the cheating of floor scale

 Cheating on electronic floor scales is a serious and ugly social phenomenon, but driven by profit, it often happens. Although the government has taken many measures to crack down on cheating, the trend continues unabated. Based on what I've seen and heard over the years. A brief introduction is given to the common methods of cheating on electronic floor scales.

1. Types of cheating

Look from the type of cheating, cheating is divided into oneself cheat cheating and outsiders, and internal and external collusion cheating, cheating in their scale is the main according to their interests need to add the cheat, cheat stranger is external personnel according to the need of interests while secretly install of the cheat, cheating in the internal and external collusion in state-owned enterprises and other large units, the internal and external collusion against unit and national interests, tell from cheating, generally has the following several ways:

 1.1. A remote control is installed on the lead wire of the analog sensor by changing the signal voltage of the analog sensor to achieve the purpose of cheating.

 1.2  remote control device is installed in the electronic weighing instrument to achieve the purpose of cheating.

 1.3  install the remote control in the electronic floor scale terminal box to achieve the purpose of cheating.

 1.4  to achieve the purpose of cheating, a two-way cheater is quickly installed at the signal plug behind the electronic weighing instrument. This remote control can be installed in a few minutes and is generally unexpected and hard to find.

 Usually, everyone thought on analog sensor floor scale cheating, cheating on digital sensors and digital instrument is difficult, but not long ago, a professional maintenance personnel on the digital instrument was surprised to find the remote control the cheat, cheat technology is advanced, the means of brillant, installation of concealment, shocking.

 2  maintenance personnel on the scale to prevent cheating common inspection methods

 2.1  check whether there is a foreign body on the sensor lead. There is nothing else on the normal sensor lead. Therefore, when there is a foreign body on the sensor lead, it should be paid attention to.

 2.2  check whether the instrument has lead seal or not, and whether the lead seal is damaged. There are extra plug-ins in the plug port of the signal line of the instrument, so as to prevent installing two cheats here.

 2.3  if there is an opportunity to check the terminal box, after opening the terminal box, please note that there should be nothing in the terminal box except the resistor and adjustable resistor under normal conditions. If there is a foreign body and additional leads, it may be a cheat.

 3  for large scale anti-cheating advice

 3.1  it is suggested that the use units should try to purchase the floor scale produced by large enterprises, the floor scale produced by large enterprises, the product quality and after-sales service, and the production qualification are generally more reliable and reliable.

 3.2  it is suggested to choose digital sensor as far as possible, and its anti-cheating function is better than that of analog sensor.

 3.3  the floor scale shall be installed with a high-strength threading tube and a high-strength thread sensor, which, on the one hand, can prevent rats from biting and on the other hand, can improve the anti-cheating ability.

 3.4  it should be suggested that the unit should install monitoring equipment to improve the safety protection level of the scale.

 3.5  it is suggested that protective net should be installed around the open foundation floor scales to prevent remote control from being installed on sensor leads.
