According to the different hardware configuration of the open-pit mine car dispatch system, the open-pit mine car dispatch system is divided into four categories:
(1) radio telephone communication dispatch system;
(2) Wired communication dispatch system;
(3) Wireless digital communication dispatch system;
(4) GPS dispatch system.
Each kind of automobile dispatching system has its own advantages and disadvantages. The advantage of radio telephone communication dispatching system is that the system is simple and the investment is low. The disadvantage is that the degree of automation is low; the advantage of wireline communication dispatching system is that the system has strong reliability and low investment, but the disadvantage is that the flexibility is poor. The advantage of the wireless digital communication dispatching system is its high degree of automation and speed. Its disadvantages are high investment and difficulty in system maintenance. The GPS dispatching system has a high degree of automation and system reliability, and its disadvantage is high investment.
GPS technology has been widely used in foreign mines and has achieved remarkable results. Therefore, GPS technology should be used when setting up an open-pit mine car dispatch system. Due to the shortage of funds in China, it is impossible to fully introduce foreign forming technologies with large amounts of funds, such as the module mining company's DisPatch system. At the same time, the DisPatch system is established for the advanced infrastructure and management system of foreign mines and is not suitable for the actual conditions of mines in China.
The open-pit mining vehicle dispatch system based on GPS technology uses advanced GPS and wireless communication technology to implement real-time monitoring of open-pit mining vehicles. The system is a radio communication network for mobile vehicles. Its network topology is star-shaped and suitable for China's reality.
Heavy Duty Wheel Alignment is exclusively for truck and bus:
5D technology of Heavy duty wheel alignment overcomes all disadvantages of 2D technology, such as mismeasurement.low precision.human factors , which are caused by following reasons:
[1]Original errors caused by wheel rim deformation cannot be eliminated by compensation;
[2]Errors caused by wheel clamp deformation can not be eliminated;
[3]Precision of truck should be higher than that of cars, but 2D technology makes it lower;
[4]Different measurement results caused by different operational approaches and strength.
5D technology of heavy duty wheel alignment adopts anti-shake measurement technology. Heavy duty wheel alignment can eliminate time errors caused by car body shake within 20 seconds, improving labor efficiency. Meanwhile, Heavy duty wheel alignment avoids problems caused by wireless and high-frequency interference. Heavy duty wheel alignment can be used at any indoor places.
