Maipu brilliance sharing LED display pre-sale site survey elements

Everyone knows that Maipu's glare LED display is a customized product. It is not a simple electronic trading product. It is a simple trading process, but involves the implementation of a complete system design scheme, including pre-sales design including Other related industries. To the after-sales construction and maintenance, many times you need a business to complete.

The following small series will share with you the essential elements of the site survey before the sale of led display:
1. Preparation before site survey:
You need to communicate with the user before departure to understand the specific requirements of the user:
1 The type and size of the display.
2 installation environment.
3 display content and methods.
4 communication methods.

2 Site survey content:
1 The state of the wall where the display is installed, the installation method (inlaid, floor-standing, hanging, wall-mounted, support, pillar) and the force. And according to the specific size of the display, confirm whether there are obstacles at the installation site to hinder the installation of the display. In the case of inlaid installation, the reserved installation slot is suitable; if the wall has decorative partitions, the user must be inquired about the wall condition; if the column screen is installed, it is necessary to understand the geological conditions. (If there is sediment at the bottom of the geological layer, it will take a long time, which will lead to the risk of the column and the screen sinking or even falling down. Don't look at it as a horse.)
2 on-site power supply situation. The capacity of the equipment room or AC transformer, whether the cable needs to be rearranged, or whether the wire diameter of the cable has been set to meet the requirements; if it is single-phase power, whether there is a ground wire; if it is three-phase electricity, whether it is a three-phase five-wire . If you need to rewire, you need to accurately measure the length of the power cord on site.
3 Understand the control position of the display and whether the communication line is unblocked. The length of the communication line required on site, and whether there are other devices that need to be connected to the display control terminal or understand the switching mode of the live signal channel; if the user does not understand anything, at least need to understand the user's application needs, especially the theater. Class user. If the user has already wired, ask if the length and quantity of the cabling are appropriate; the normal synchronization system should use less than 120 meters of super five types of network cables, and the length of non-super five types of network cables should be lower; if the number is insufficient, the number of corresponding network cables must be increased. If it is too long, it must use a suitable fiber optic cable, use multimode fiber within 500, and use single mode fiber over 500 meters. There must be spares for both the network cable and the number of fibers.
4 tools that need to be carried, such as a tape measure or a laser ruler. Whether scaffolding is required or the user provides scaffolding. Whether the computer is provided by the user.
5 on-site external environment. Whether it is necessary to pay attention to moisture protection when installing indoors, whether it is necessary to pay attention to the details of waterproofing and lightning protection measures when installing outdoors; whether the location is by the sea, by the chemical plant, the degree of air salt, alkali and acid. Another outdoor screen user needs to observe the viewer's viewing distance, display height, and sunlight orientation.
6 Take all the situations encountered at the scene with the camera as much as possible, and take different details in different angles.
7 Whether the user has special requirements, whether it can be realized and the difficulty of the project if there are special requirements.
8 If the construction is responsible for the construction, it is necessary to go to the local to understand the specific location of the steel market and building materials market.
Special considerations for adding outdoor screens:
(1) Maipu radiance display is installed outdoors, often exposed to the sun and rain, wind chui dust cover, and the working environment is bad. If the electronic equipment is wet or seriously damp, it may cause a short circuit or even a fire, causing malfunction or even fire, resulting in loss.
(2) The display may be subject to strong electric and magnetic attacks caused by lightning.
(3) The ambient temperature varies greatly. The Maipu brilliance LED display itself generates a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, thus making the display system unable to work normally.
If the work flow is not arranged in advance, traveling to a distant city for site survey work will have a major impact on the installation of the display. At the very least, it will cause some trouble to the user and affect the service level of the company. Not all displays must be visited by the merchants in person. If it is not convenient to go to the site, according to the above situation, after selecting the display and control system, the user needs to cooperate with the site survey if conditions permit. , or the merchant to understand the situation through other means.
