1. IP55 and IP65: Differences in core grades of outdoor protection.

IP(Ingress Protection) protection level consists of two digital indicators: dustproof and waterproof. The higher the value, the stronger the protection performance. The specific differences between IP55 and IP65 are as follows:

The first number of IP55 is "5": it means that it can prevent a large amount of dust from invading, only allow a small amount of dust to enter without affecting the normal operation of the equipment, and it is suitable for ordinary outdoor environment with low dust concentration;

The first number of IP65 is "6", which means it is completely dust-proof, and can be used for a long time in the north where dust storms frequently occur or in industrial areas where dust is concentrated, so as to avoid the problems of short circuit and poor heat dissipation caused by dust accumulation.

Waterproof grade comparison

The second number of IP55 is "5": it can resist low-pressure jet water (such as rain erosion) and is suitable for areas with less precipitation;

The second number of IP65 is "5": the waterproof ability is the same as that of IP55, which can cope with rain washing and water gun spraying during cleaning, and can meet the foundation waterproof needs of rainy areas in the south or coastal cities.

Ruiguan's outdoor advertising machine strictly covers IP55-IP65 grade standards, and the waterproof design of the whole machine adopts automobile door-type sealing structure, and steam sealing tape is adopted at the junction of cabinets to control the intrusion of dust and rainwater.

2. -45℃ to 55℃: Stable operation under extreme temperature.

If IP protection can adapt to the extreme temperature of water vapor and dust, it is the core to deal with the temperature difference in different regions. -45℃ is close to the extreme low temperature in the northeast winter, which will lead to the performance attenuation of common equipment components; 55℃ is close to the surface temperature of equipment at noon in midsummer in the south, which is easy to cause the stability problem of electronic components.

Ruiguan's outdoor advertising machine realizes the stable operation of this temperature range through the following design:

Special screen: wide temperature LCD panel is used to reduce abnormal display at low temperature and afterimage and brightness attenuation at high temperature.

Intelligent temperature control system: built-in temperature sensor, automatically start the heating module at low temperature, and quickly cool the high temperature through the combination of high-efficiency heat sink and fan to ensure that the core components are at suitable working temperature;

Weathering material: galvanized steel plate is selected for the fuselage shell to reduce the risk of aging and deformation caused by long-term exposure, and the screws are rustproof to ensure the stability of details.

3. The necessity of strengthening protection: to meet the challenges of complex outdoor environment.

The complexity of outdoor environment far exceeds that of indoor environment: plum rain causes equipment to be wet, thunderstorm causes voltage fluctuation, sandstorm causes parts to wear, ice and snow affect heat dissipation, and high humidity and high salt fog in coastal areas will also corrode internal components.

Equipment failure not only causes maintenance costs, but also leads to the interruption of advertising and affects the reach of brand information. Ruiguan, according to the needs of different scenes, ensures the long-term stable operation of the equipment in various environments such as cold in the north, hot and humid in the south, urban streets, industrial areas and other scenes through the precise protection design of IP55-IP65 grade, and continuously delivers advertising content.

The reliability of outdoor advertising machine is the foundation of brand continuous communication. The differentiated application of IP55-IP65 protection level and the temperature adaptability from-45℃ to 55℃ together constitute the core guarantee for the stable operation of equipment. Only by meeting these standards can the advertising information reach the target audience effectively.
