(Suite) C, écran d'affichage LCD extérieur avec machine à panneau de batterie -50 ℃ ~ 110 ℃ large adaptation à la température : fonctionnement stable à température extrême.Support technique de base pour une conception à large température : Compte tenu de l'environnement de température extrême extérieur, l'écran d'affichage LCD de la machine à panneau de batterie extérieure adopte un double système de refroidissement de "dissipation thermique active + dissipation thermique passive" -dans un environnement à haute température, la chaleur générée par le module de rétroéclairage de l'écran d'affichage LCD de la carte principale et de la machine à panneau de batterie extérieure peut être rapidement exportée par le ventilateur de refroidissement de la structure refroidi par air (vitesse réglable) combiné à un substrat de refroidissement en aluminium de qualité militaire, et la température des composants internes du noyau peut être contrôlée à 65 ℃ même sous une exposition à haute température de 110 ℃. Dans l'environnement à basse température, le module de rétroéclairage de l'écran LCD de la machine à panneaux extérieurs avec batterie dispose d'un chauffage intégré, qui peut augmenter la température centrale de l'écran au-dessus de 0 ℃ dans les 5 minutes après la mise sous tension, afin de réaliser un démarrage rapide à -50 ℃ et d'éviter le retard d'image et de réponse de l'écran LCD en raison de la basse température.

Optimisation à large température des composants clés : La carte principale de l'écran LCD de la machine à panneaux extérieurs avec batterie adopte des composants à large température, qui peuvent fonctionner de manière stable à la température de stockage de -45 ℃ ~ 80 ℃ et à la température de fonctionnement de -50 ℃ ~ 110 ℃, afin d'éviter le gonflement du condensateur causé par la basse température et la combustion des puces causée par la haute température ; Après l'optimisation de la décharge à basse température, la batterie à lame peut toujours maintenir une capacité de plus de 80 % à -50 ℃, sans se soucier de l'atténuation de la durée de vie de la batterie à basse température, et elle convient à différents scénarios climatiques tels que les zones froides du nord et les zones à haute température du sud.

Environmental adaptability supplement: except temperature, outdoor LCD display screen equipment with battery signboard machine can operate in 10%~90% humidity (no condensation). In southern rainy season and coastal humid areas, the internal moisture-proof coating can isolate moisture and prevent short circuit of circuit board; After high and low temperature cycle test (repeated switching at -50℃~110℃ for 1000 times), the whole machine has no attenuation, which ensures the stability of long-term outdoor use and reduces the failures caused by environmental factors.

D, outdoor machine with battery signboard LCD display screen blade battery and core configuration: battery life and functional support

Endurance of 50,000 mAh blade battery: equipped with 50,000 mAh large-capacity blade battery, it can meet the demand of 14-hour continuous work after 7 hours of charging (calculated by playing 1080P video with medium brightness), without external power supply, and the LCD display screen of outdoor machine with battery signboard is suitable for outdoor scenes without power supply conditions (such as temporary exhibitions and open-air markets); The battery supports 24V input voltage, has overcharge, overdischarge and overcurrent protection, and has no risk of bulging and leakage after long-term use. Its service life is synchronized with the screen (about 60,000 hours), which reduces the cost of battery replacement in the later period.

Motherboard performance and expansion function: The outdoor LCD display screen of battery-powered signboard machine adopts Cortex-A7 architecture CPU (clocked at 1.2G) with DDR3 1G memory, and the built-in memory can support up to 32GB TF card expansion, which can store a large number of video and picture materials; The operating system is Android 7.1.1, and the LCD display screen of outdoor battery signboard machine supports 1080P HD video decoding (compatible with more than 30 formats such as AVI, RMVB and MKV) and image formats such as BMP and JPEG. The network supports 3G/4G WAN, Ethernet and WiFi, which can remotely update the material and control the playback content. At the same time, it is equipped with four USB interfaces (two host+two extensions), which supports USB upgrade and SD card upgrade, and is convenient to maintain. The LCD display screen of outdoor battery signboard machine has a built-in dual-channel stereo surround amplifier system (8 Euro 2×10W), and the sound quality is clear and loud. The LCD display screen of outdoor battery signboard machine can meet the outdoor hearing needs without external speakers.
