Application of unattended automatic weighing in coal transportation in power plants

The most cumbersome part of the daily management of a coal yard is the entry of coal vehicles and weighing calculations. If manual management is required, the workload is very large and management loopholes are prone to appear.
The main problems in the management of coal coming from automobiles are as follows:
A large amount of coal coming from cars is difficult to pick up and unload: According to the daily average pick up and unload of 20,000 tons for 12 hours/working day, the average net weight of each vehicle is 30 tons, and the average need to pick up and unload 55.6 vehicles per hour, that is, one needs to be picked up and unloaded every minute Automobile, and each vehicle from sampling to over-balance cannot meet this requirement from the existing configuration.
The labor intensity of personnel is too large and the degree of automation is low: in order to meet the daily average loading and unloading volume, the only way to make up for the lack of time is to rely on the 24-hour operation method, and the 24-hour operation personnel increase more, the intensity is greater, and the night safety operation coefficient is relatively high. Low.
Difficulty in on-site management: Due to the large number of coal yards and the large flow of coal-pulling vehicles, it has caused great trouble to on-site management.
The on-site data transmission is not timely and the accuracy is poor, which affects the statistical settlement work.
The system has designed an unattended system in response to the above problems. The system mainly includes on-site acceptance and on-site management. The system uses positioning technology, graphic recognition technology, voice prompts, traffic light prompts and other technologies to improve work efficiency and effective This eliminates management loopholes and greatly improves the on-site management level.
The unattended weighing system realizes fully automatic management of vehicle weighing in and out, rationalizes management processes, standardizes management concepts, improves work efficiency, provides timely and accurate information services for production and operation, and realizes informatization of coal yard management:
Use computer and information technology to realize the computerized process management of the entire weighing process of vehicles entering and exiting the coal yard, and achieve the purpose of standardizing management, curing the process, eliminating management loopholes, and improving the overall economic benefits of the coal yard.
The unattended weighing system provides an external interface for weighing data, and can be seamlessly linked with the existing application system of the coal yard.
