1. System background and significance
At present, in open-pit coal mines or mining enterprises, there are a lot of engineering vehicles that are responsible for the tasks of pulling soil, pulling sand, and pulling media. These vehicles operate 24 hours a day and there are many vehicles. Therefore, coal mining enterprises must assign special vehicles at designated locations every day. The staff counts the number of vehicles, counts how many times the vehicles are pulled every day, and also checks whether each vehicle is full every time and how many times a day is pulled, and also checks whether each vehicle is full every time, whether it is empty, and return Whether the vehicle is sticky or not, this kind of error will bring economic losses to the enterprise and the owner, and cause conflicts, and it is believed that there will be human accidents in the points, and fraud.
This system aims to improve the accuracy of counting; save time and improve efficiency, which is good for car owners and coal mines; and reduce economic losses caused by human factors. The system configuration has functions such as automatic card issuance, video capture, voice prompts, LED screen display, etc. (optional)
2. Working principle
First, install a vehicle for each vehicle that needs to be countedelectronic label, And then set up a counting acceptance room in the place that needs to be monitored (it can also be a virtual acceptance room that leaks, this depends on the actual site), and then install the 2 readers at the corresponding distance, and 2 readers The distance between the reader is 20-30 meters, and it is connected to the host computer. The user can adjust the reading distance of the card reader according to the on-site situation. Generally, the distance should be controlled at about 10 meters, and the angle of the card reading should be adjusted. When everything is ready, you can start the technical management software to perform counting statistics. It should be noted that: in the card reading area, the vehicle should not stay for too long.
When a vehicle enters, the two card readers will automatically read the vehicle card number. The card reader will send the read card to the server for automatic analysis and request the next step. If the card belongs to If it is a legal vehicle, the system will perform data registration processing. After completing a job, the computer records the vehicle’s card number, elapsed time and other information at this time. Store the data in the computer’s database. Because the vehicle tag information may be read repeatedly within a period of time, we can set a card reading time, for example, if the card number is the same within 10 minutes, then it will only be recorded once.
When the vehicle returns, the working principle is the same. With two card readers, it is possible to accurately determine the entry and exit of the vehicle, as well as the number of entries and exits. In this way, the daily frequency of the vehicle can be accurately counted, and the LED and sound system can be used to display and broadcast in real time.
