LED advertising screens have been developed in China for more than 20 years, and have been fully covered into people's field of vision. LED display screens of various shapes can be seen everywhere on the road. The content displayed by the LED display screen can be text information or image or video. The situation is revealed. LED advertising screen is not just a simple display product, but a combination of optics, electronic applications, mechanics, and aesthetics.
Let us first analyze the composition of the LED advertising screen, which mainly consists of LED module, LED control card, LED power supply, short cable, long cable, 5V power cable, 220V power cable, strong cable and 380V power. Distribution box, video processor, amplifier audio, heat dissipation, structure and other components.
(1) LED advertising screen appears regular large black is not bright
You can check whether the software partition has coverage. Secondly, check if the network cable and power cable are loose. Check whether the power supply is powered again. If the power supply is normal, you can check whether the receiving card scan is normal. I believe that through this series of troubleshooting schemes, the LED advertising screen can be solved. Effectively excluded.
(2) LED advertising screen in a row of past flashing, similar to garbled situation
This problem can be judged as the signal supply of the single-row LED module is not normal. The elimination method is to directly jump the long-row cable from the receiving card to the LED module with problem. If it is displayed normally, it proves that the LED module is Normally, plug the cable into the right side of the block module to check if the previous module is normal.
If it is normal, then replace the short cable between the two LED modules. If it is found that the block module is not normal, you can determine that the LED module driver chip is faulty, and send it back to the LED advertising screen manufacturer for repair or site. Replace it.
Basically, the LED advertising screen encounters so many problems, or a whole block, or partial, it can be detected according to the above scheme. If you encounter other LED advertising screen failures, you can give feedback to the company that you purchased the LED screen.

1 Boom Drilling Rig

The 1 boom drilling rig is the main drilling equipment in the underground hard rock mine.
Manipulator drilling rig with high level of automation and computerization is not very attractive to mine.
The mine hopes to use the trolley with compact structure, flexible movement, high reliability, high efficiency and high accuracy.
Small enough to enter the shaft through a small section
Maneuverable and flexible enough to walk in winding and inclined passages
The versatility can be used to drill hole, bolt hole and cut hole in all directions.
In recent years, several major rock drilling equipment manufacturers in the world, in order to meet the requirements of mechanized mining of thin ore bodies, have successively developed a variety of small rock drills with high power, which can be used to complete the rock drilling operations that could only be completed by pneumatic drill, so as to significantly improve the efficiency of rock drilling and reduce ore dilution rate.

Hydraulic drilling jumbo is mainly used for tunneling construction in metal mine and other underground engineering. One drilling boom, advanced hydraulic rock drilling system and anti-jamming mechanism ensure the jumbo rapid drilling speed and high efficiency. This jumbo features of great mobility, short turning radius and strong gradeability, thus can improve working environment and get efficiency, quality development.

Robust universal drilling boom creates ideal face drilling coverage. Automatic parallelism and 360 degree roll-over enable easy, fast and accurate positioning for face drilling, sideway drilling and bolt hole drilling.

The layout of components provides excellent vision for the operator in drilling and travelling.Powerful and well balanced 4-wheel drive chassis allows the rig to move through limited space and tough terrain in the mines.

Duo-circuit service brake and enclosed multi-disc parking/ emergency brake ensure safety in tramming and on ramp slope.
Field proven high frequency hydraulic drifter delivers high performance. Trapezoid shaped percussion piston optimizes shock wave transfer efficiency, enhancing penetration and decrease drilling consumables costs.

Comfortable operator station provides safe working condition. Many automatic features simplified the drilling control and helps the miners to concentrate on fast and accurate drilling.

All service points are easily accessible, which simplifies daily routine maintenance for this 1 boom drilling rig in rock ore quarry and underground tunnel drilling blasting DTH purpose.
