1 . Structure: According to the enclosure protection grade GB4208-93standard, the protection grade of the integrated chassis and constant temperature system adopted by this equipment will reach IP55 all-outdoor equipment standard, and the design shall follow the following principles:

(1)The shell is made of 1.5mmSGCC galvanized steel plate, sprayed with Aksu outdoor special plastic powder, and the protection life is more than 10 years.

(2)The waterproof groove and air inlet and outlet holes of the shell structure are designed to be waterproof, meeting IP55 protection level.

(3) Dust-proof design:

The air inlet and outlet are designed with a special medium and high-efficiency dust-proof filter, which can filter the dust in the air and prevent mosquitoes from entering the machine. The design of disassembly and assembly is minimal, which is convenient for customers to maintain regularly.

(4)The protective glass in front of the whole screen is made of full fit:

 Ultra-white tempered glass, with light transmittance ≥ 97%, high light transmittance and anti-reflection.

(5)The whole machine adopts the front and rear door opening method, which can facilitate the maintenance of the internal display screen, heat dissipation components and electronic components.

(6)The whole machine adopts modular design, which is convenient for installation and maintenance.

(7)The design and installation holes of the bottom plate of the whole machine can be fixed by tension and explosion bolts or embedded threaded rods.

Display:

(1)High-brightness industrial LCD screen is adopted, with the brightness of 2000nit

(2)High resolution, high contrast, high brightness, greatly improve the layering of the picture, and better show details.

(3) Long-term use of LCD screen with automatic afterimage elimination function, ultraviolet protection, heat insulation to sunlight, automatic light perception, green energy saving protection.

(4) has the adaptive function of black level extension, which enhances the depth of field and layering of images.

(5) Using outdoor professional high-brightness LCD screen, the video image is brighter and the stereoscopic impression is stronger.

(6)16.7m color, the picture is more natural.

(7)Ultra-long service life, 7*24hours of uninterrupted work.

2.Electrical:

(1)Electrical protection: leakage, overload, overvoltage protection, lightning protection device, overtemperature protection, etc.

(2)Audio: Dual-channel stereo surround power amplifier system is adopted, and the output power is 10W.

(3)Design standard of working environment temperature: Adopt the principle of modular design, sustainable and maintainable design.

(4)Automatic photosensitive adjustment: the screen backlight adopts automatic ambient light sensing, and the screen brightness can be adjusted in real time to meet the requirements of clear image display in the environment of strong direct sunlight, so that the screen will not be dazzling at night, saving energy and protecting the environment.

Heat dissipation:

(1)adopts the integrated intelligent direct ventilation and heat dissipation system, and the professional and special air duct heat dissipation design

(2) The internal air of the whole machine is circularly exchanged with the external air.

 After the external air enters the dustproof net for filtration, it is divided into two air cycles, namely, the front screen and the back screen, to ensure that the internal temperature reaches the temperature difference of 10℃, compared with the external temperature.

(3)independently researched and developed the fan speed control board, which can automatically adjust the fan speed according to the internal temperature of the machine.

(4) It is equipped with high-temperature automatic power-off protection function. When the internal temperature of the machine is abnormally high and exceeds the normal working range, the control system will power off the main components such as the display screen, and at the same time, the fan will continue to run at full speed to dissipate heat, fully protecting the display screen and main components.

Intelligent patrol monitoring system:

Temperature monitoring: the rotation speed and running state of each fan inside the whole machine can be monitored, and the initial starting temperature value and the maximum rotation speed temperature value of each group of fans in front of/behind the screen can be set and adjusted by regions, so as to realize intelligent temperature control. Range: ≤-35~, ≥96℃

Man-made damage monitoring: if someone knocks or collides with the equipment, the monitoring system will automatically report to the server. Range: ≥ 8kg±5%, adjustable from 0.1KG~20KG.

Anti-theft monitoring: the door of the equipment is pried by someone, and the monitoring system automatically reports to the server. Value range: ≤ 20mm±5% adjustable

Smoke monitoring: If there is an accident inside the equipment and smoke is generated, the monitoring system will automatically report it to the server. Adjustable range ≥450~10000PM

Flooding monitoring: When there is heavy rain in the installation place of the equipment, when the water level reaches the dangerous level, the monitoring system will automatically report to the server and cut off the power supply. Prevent personal injury caused by heavy rain flooding and electric leakage. Range: ≤0.1m adjustable

The information release system is perfectly integrated with the intelligent patrol monitoring system for real-time monitoring: the docking protocol of the patrol monitoring system can be provided to realize the automatic alarm of the running state of outdoor high-brightness LCD digital signage.
