Solar energy electronic tag for object location WE-T78 background material
The global mining industry is experiencing a new change, mining as a pillar industry of the country, with the decreasing mineral resources, the gradual reduction of ore grade, mining difficulty is getting bigger and bigger, mining enterprises in pursuit of high-quality development more and more urgent; in order to enhance the efficiency and safety considerations, the Internet of Things (IoT) technology and the combination of mines is becoming increasingly close to the intelligent mines are gradually coming into people's view.
Many mines are still using manual car counting, which can lead to a lot of problems, the
- (a) The gradual increase in the cost of labor.
- (a) The frequent occurrence of miscounting and omission of information due to staff negligence.
- reports cannot be generated automatically.
- It is difficult for managers to achieve real-time access to yield data.
- Regulatory system data cannot be interconnected, data cannot be cross-referenced, and no evidence can be found in case of problems;
- Mining vehicles to and from the weighbridge time is not fixed, more vehicles, resulting in congestion, easy to cause security risks.
- High weighing capacity, low weighing efficiency.
- There are a lot of manual interventions, drivers need to contact with the owner of the cargo, mining sand and gravel multiple points offline, sometimes resulting in disputes or corruption
Currently there are many kinds of metering systems, such as floor scales and vehicle scales. Weighbridge construction costs are high, can not be unattended, and to a certain extent will affect the production efficiency, the use of the period also need to be frequently calibrated, the poor conditions of the equipment failure rate is high, the maintenance workload. Truck-mounted weighing systems also face high installation costs, maintenance workload, and weighing accuracy is difficult to ensure. For most of the mining enterprises, the accurate number of production vehicles can meet the production requirements.
Customer Cases
The system integration company utilizes World Power'sZigBee Positioning Productsrespond in singingGateway Transmission ProductsThe company has implemented a complete set of solutions and developed an unattended metering system for use in mines, which can directly replace the traditional manual counting (saving labor costs), and at the same time, can output accurate metering data of haulage trucks and shovels, and moreover, it supports a wide range of statistical analysis functions such as mixing and blending grade calculations (which can be used to assist in blending and blending), equipment output by the hour, and statistics on the output of the driver, etc., and it has a powerful report output function.
Installation of serial readers on excavatorsWE-RW01respond in singing4G DTUInstallation of solar-powered electronic tags on dump trucksWE-T78When the dump truck is close to the excavator for loading (generally not less than 10 minutes), the excavator automatically judges which dump truck the minerals are loaded to according to the card reading information, and the relevant information is reported to the platform software in real time through the DTU.
After the dump truck leaves the digger, it goes to the weighing point and gets the weight of that truck of minerals by weighing and uploading it to the platform. In this way, each time the digger digging ore handed over to that dump truck, how much weight, it is all clear, naturally, the day's workload is also clear.
Through automated statistics, you can avoid the errors of manual statistics, compress the space of fraud, and make the statistical results more accurate.

Technical difficulties
When there are multiple dump trucks attached to the excavator, it is important to be able to correctly identify which dump truck is currently being loaded. There is the following method:
1, the left and right sides of the excavator are installed to read the card antenna, the dump truck can read the relatively accurate distance value no matter which side it approaches from.
2. Judge according to the time the dump truck stays, ignoring the dump truck that passes by. Dumper trucks that need to be loaded should stay at least 10 minutes.
3, plus manual confirmation, to the excavator with a small terminal with a screen, from near to far to display the excavator, as well as the excavator's relevant information (such as license plate number, driver's name, etc.), by the operator of the excavator manually to select and confirm the
