With the continuous improvement of mining technology, the increasingly advanced mining equipment and the continuous growth of energy demand, the mining output has been greatly improved, and the weighing work of weighbridge vehicles has become heavy on a daily basis.
Traditional weighing mode
In the previous weighing management method, it was completely based on manual recording of vehicle information, weighing information, capital situation and statistical summary of information, etc., and manually directing the vehicle to enter and exit the weighing. This method of manual recording not only has high work intensity, low operation efficiency, and is prone to safety accidents, but also has a serious phenomenon of missing and miscollecting, and the probability of error is high.
secondly, due to the lack of effective supervision, there is a high possibility of human cheating behavior, which may lead to the loss of assets of enterprises; Moreover, the obtained data cannot be shared in real time through network transmission, but by manually filling in documents and sending them to other relevant departments such as finance, sales, warehouse, etc., it is difficult to understand the operation dynamics of vehicles in the mine in time, and it is not convenient to carry out timely and effective management.
license plate recognition technology
Therefore, it is necessary to introduce license plate recognition technology into the weighbridge management system to automatically identify the vehicles entering and exiting the scale, uniquely authenticate the vehicle identity, automatically register and inspect the vehicle, and realize the automation of the monitoring and management of the weighing vehicle. License plate recognition can generally be divided into three parts: license plate positioning, character segmentation and character recognition. In order to construct a high-performance license plate recognition system more effectively, on the basis of the extraction of license plate character outlines, projections and grid coding features, SVM is used to construct a mining weighbridge license plate recognition system with information fusion, which makes full use of the redundant and complementary information of each feature, which greatly improves the accuracy and credibility of recognition, and is of great significance for improving the efficiency and efficiency of enterprise operation.
Unattended weighing of mining scales
Although our country's mining enterprises have realized the automation of vehicle weighing, the statistics of relevant data and process control in the weighing process are indeed mostly manual operations, and the traditional license plate camera recognition rate is low, which directly leads to the weighbridge management personnel not only high work intensity and weighing multiple links are easily affected by human factors, which directly affects the work efficiency and experience interests of enterprises. Therefore, according to the rich experience of the mining industry and many in-depth exchanges with customers, the system can realize automatic weighing and measurement, automatically print the weighing list, documents, gross weight, tare weight can not be manually entered, there are computers directly from the weighing instrument to collect, save the data to the cloud, management personnel only need to find all the weighing records on the computer, no need to guard the weighbridge. Through the network interconnection feature, only one data administrator is needed, and one or more weighbridges can be monitored in real time to eliminate the interference of human factors. At the same time, the leader can monitor the real-time image information and real-time data information of each weighing room in the office.
