Intelligent truck scale internet-of-things system

Abstract

The invention provides an intelligent truck scale internet-of-things system which comprises electronic truck scales provided with weighing sensors. Each electronic truck scale is connected with one positioning monitor through an interface. A plurality of positioning monitors are connected with an intelligent embedded terminal at a manufacturer servicer through a mobile communication network. The intelligent embedded terminal is connected with a mobile communication terminal through a wireless network. The intelligent truck scale internet-of-things system can carry out real-time monitoring and analyzing on operation of equipment through the utilization of the internet-of-things technology, and various faults causing weighing inaccuracy can be found in the first time and initiatively reported to a manufacturer terminal remotely, so that the manufacturer can inform users of the faults of the truck scales in the first time and quickly solve the faults. Therefore, loss, caused by the weighing inaccuracy, of the users is prevented. Meanwhile, the innovation that the electronic truck scales are upgraded from passive 'anti-cheating' to initiative 'against-cheating' is achieved.

Description

technical field [0001] The invention relates to the application fields of weighing measurement and the Internet of Things, in particular to an Internet of Things system of an intelligent truck scale. Background technique [0002] The existing electronic truck scale is composed of a load-bearing force transmission mechanism (scale platform), a strain-type pressure load cell and a weighing display device (digital instrument). The weight is carried by the weighing platform and the force is transmitted to the load cell under the weighing platform, the elastic body on the load cell is deformed, and the impedance of the bridge circuit of the strain gauge attached to the elastic body is out of balance, and the output is proportional to the weight value. After the electrical signal is processed by the processing circuit, it reaches the digital instrument to display the weighing result. At the same time, the user realizes the processing and control of the weighing electrical sign...

Problems solved by technology

[0003] Existing electronic truck scales (including unattended system electronic truck scales) can only achieve unattended weighing in the weighing room, automatic control of the weighing process, and automatic recording of vehicles and weighing data. Once the electronic truck scale and unattended If the system fails, it needs to be repaired and maintained manually, which is still a passive diagnosis

The inaccurate weighing of the truck scale (including the inaccurate weighing caused by cheating) can be traced back to the problem of the scale body, sensor or circuit. It takes a period of time for the wrong weighing to be discovered by the user, and the unattended system It is more difficult to detect weighing failures in time, and users have already caused huge losses when they find that weighing is inaccurate

As the basic equipment of industry and circulation industry, truck scales have brought hidden dangers to the healthy operation of various industries, and the huge losses caused by this have not been fundamentally solved for a long time as an old problem in the industry. There is an urgent need for a smart car Heng IoT system solution
