The unattended weighing system is an intelligent weighing system based on modern sensor technology and Internet of Things technology. The unattended version of the weighing management system integrates hardware equipment such as RFID radio frequency devices, infrared beams, cameras, automatic barriers, sound and light alarm devices, and SMS group devices, and realizes unmanned and information-automated weighing and weight checking operations through the software automatic control system.

The unattended weighing system realizes the automation of weighing and weight checking by the following means:

1.

The RFID radio frequency device is combined with the software to realize the automatic identification of vehicles and avoid the mixing of materials. By developing the corresponding software module to connect the RFID radio frequency device to the unattended system, the automatic identification of vehicles at various locations such as weighbridges and warehouses can be realized, so as to effectively control the dynamics of vehicles in the factory area and ensure that vehicles will not be mixed due to entering the wrong warehouse when loading and unloading materials.

2.

The infrared beamer ensures that the vehicle is fully weighed to avoid multiple vehicles weighing at the same time and causing weight checking data errors. Install infrared transmitters around the scale. When the vehicle is not fully weighed or two or more vehicles are weighed at the same time, the infrared transmitter signal will be blocked, the system will automatically alarm, and the weight measurement will be stopped.

3.

There are various financial and statistical interfaces, which effectively integrate corporate resources, and pre-sales, after-sales, and financial management are all in place. The unattended weighing system includes various statistical and financial modules, which can be effectively combined with the company's financial ERP, management ERP and other systems, so that weighing measurement is effectively integrated with corporate finance and corporate management. All weight measurement data can be queried, counted, calculated and stored in different categories.

4. The combination of SMS group sending device, camera and software allows customer leaders to understand all aspects of weighing while sitting in the office. The unattended system can send the alarm information that occurs during the weighing and weight measurement process, as well as other information required by the customer, to the company leader's mobile phone in the form of SMS, so that the leader can understand the weighing situation in time. The leader can also view the real-time weight measurement image through the video system.

5.Industry application cases

Unattended truck scales are widely used in various industrial scenarios, especially in enterprises such as mines, cement plants, 

building materials plants, steel plants and power plants. These places have a large number of transport vehicles entering and exiting every day,

 which need to be weighed and recorded. Traditional manual operation is not only time-consuming and labor-intensive, 

but also prone to errors and cheating. Unattended truck scales effectively solve these problems through automation and intelligent 

management,improving management level and economic benefits. ‌

6.Future development trends

With the continuous advancement of technology, unattended truck scales will become more intelligent and integrated. In the future, 

more artificial intelligence and big data analysis technologies may be integrated to further enhance the system's automation

 level and data processing capabilities.In addition, the modular design of the system also makes maintenance and upgrades more convenient, 

adapting to changes in demand in different scenarios. ‌
