We all know that led display belongs to custom products, not like general electronic consumer products, is a simple process of buying and selling, but involves the implementation of a complete set of system design, from pre-sale including other related industry design to after-sale construction installation and maintenance, many times need to be completed by the merchant.
The following small series to share with you the led display field survey before sales need to pay attention to:
1, the site survey before preparation:
Need to communicate with the user before departure, understand the specific requirements of the user:
( 1 ) the type and size of the display screen.
( 2 )installation environment.
( 3 ) display content and way.
( 4 ) communication mode.
2 site survey content:
( 1 ) display screen installation location of the wall state, installation method ( mosaic, floor type, suspension type, wall type, support type, pillar type ) and stress. And according to the specific size of the display screen, confirm the installation site whether there are obstacles hinder the installation of the display screen.
( 2 ) the power supply situation. The capacity of the machine room or AC transformer, whether the cable needs to be rearranged, or whether the wire diameter of the arranged cable meets the requirements
( 3 ) understand the control position of the display screen, communication line is smooth.
( 4 ) need to carry tools, such as tape or laser ruler.
( 5 ) the external environment. Whether to pay attention to damp-proof installation in indoor, whether to pay attention to waterproof and lightning protection measures in outdoor details;
⑥ take photos with cameras as far as possible of all the situations encountered on the site; and take photos of different angles and details in place.
All landowners whether users have special requirements, have special requirements, whether can realize and engineering difficulty.
Today such as by the merchant is responsible for the construction, but also to the local understanding of steel market and building materials market specific position.
Additional outdoor screen issues to be considered:
( 1 ) display installed in the outdoor, often in the sun and rain, the wind blowing dust cover, working environment is bad. Electronic equipment is wet or seriously be affected with damp can cause short circuit or even fire, cause failure or even fire, resulting in loss.
( 2 ) the display screen may be caused by lightning strong magnetic attack.
( 3 ) the ambient temperature changes greatly. The display itself will produce a certain amount of heat when it works. if the ambient temperature is too high and the heat dissipation is not good, the integrated circuit may work abnormally or even be burned down, so that the display system cannot work normally.
