A, The whole machine structure waterproof
At present, outdoor lcd advertising machine waterproofing is only used. The waterproof structure of the car can reach IP65 b and the heat dissipation scheme.
There are four heat dissipation schemes on the market for reference.
1, Air cooling heat dissipation
2, Air conditioning heat dissipation
3. Heat exchange and heat dissipation
4. Water cooling and heat dissipation
In outdoor lcd advertising machine, air cooling is the most widely used cooling method. Air-cooled heat dissipation is a kind of heat dissipation method developed by using speed regulating fan combined with professional heat dissipation scheme. Its advantages are low power consumption and low cost. This helps to reduce the cost of later operation. However, the disadvantage is that the protection level is low, which can only reach IP55. Regularly clean the filter screen and check the running status of the speed regulating fan. Applicable to most parts of the country, except northeast, northwest, Hainan, areas with relatively high humidity, coastal cities and heavily polluted areas.
Outdoor lcd advertising machine air conditioning heat dissipation scheme is the most extensive heat dissipation method for external use. Its advantages are large heat dissipation, high protection grade (IP65), wide application range, stable performance and long service life. Advantages include advantages and disadvantages: high power consumption, high construction cost and high operating cost. Suitable for all parts of the country, the advantages of heat exchange and heat dissipation: low power consumption (close to air cooling) and high protection level (IP65). Disadvantages are: high cost (higher than air conditioning) and low heat dissipation. It can only be applied to areas with particularly suitable climate.
Outdoor lcd advertising machine water cooling system is not very mature in the whole technology, so it is not recommended to use it.
C. Outdoor lcd advertising machine Brightness Selection Brightness is one of the important parameters of outdoor high-brightness screen. At present, there are two backlight modes: linear and side lighting. The direct backlight has high brightness, and the side illumination brightness is only suitable for small-size screens (screens below 32 inches).
D, Playback mode:
So far, there are two ways to play outdoor lcd advertising machine, Android and PC (small computer) are widely used. Of these two modes, pure advertising is more suitable for playing Android, which can control multiple devices remotely at low cost and truly realize cross-regional remote control. And the Android version of the software is free to use. The PC solution is mainly used to make the touch more flexible. Of course, the Android version can also do the touch function. This mainly depends on the needs of customers. Touch software is customized by the customer (Party A). Because the content of the touch is set by Party A..
E, outdoor lcd advertising machine playback control:
Now the remote control has realized this function, the main difference is that Android is free to use, and X86(PC) information distribution system charges (point-by-point charge, with more than 400 points less and more than 300 points more) according to customer needs.
F, outdoor lcd advertising machine networking mode:
There are three ways of networking in the market:
Network cable, wifi, 3G/4G networking
Wired networking: networking is more stable, and the installation cost will increase in the early stage, which is suitable for short-distance use (residential area).
WIFI networking: the cost is low, and the restrictive factor is the regional limitation of wifi hotspots, which is generally used in shopping malls and shops.
