  • the detection range is wide, allowing users to keep track of the current set-top box configuration information, operating status, performance parameters, etc.; it can also detect whether there is a fault during use, such as whether a branch power supply is short-circuited or abnormally powered down, Whether the hardware interface is normal, whether the temperature of the main chip exceeds the set temperature, prompt the user or the set-top box to handle the fault when there is a fault, and give the corresponding user self-test plan. If the fault cannot be eliminated, give the contact information and address after the sale.
  • the problem that the existing set top box has a small detection range and cannot be detected and faulty at work is solved.

Abstract

La présente invention concerne un système destiné à détecter et à afficher des paramètres de rendement d'un boîtier décodeur (10) et un procédé associé. Le boîtier décodeur (10) comprend un module de détection de configuration (100), un module de détection de puissance (200), un module de détection d'interface (300), et un module de détection et de régulation de température (400). Le module de détection de configuration (100) acquiert et stocke des informations de configuration de base concernant le boîtier décodeur (10) en temps réel, et transmet, selon une instruction d'affichage de configuration, des données des informations de configuration à un écran d'affichage (20) destinées à un affichage ; le module de détection de puissance (200) détecte le niveau haut et bas d'un bit indicateur de puissance de chaque module de puissance en temps réel, et détermine si le module de puissance correspondant est normal, et guide l'utilisateur sur l'écran d'affichage (20) lorsque le module de puissance correspondant est déterminé comme étant anormal ; le module de détection d'interface (300) détecte un état de fonctionnement de chaque interface, et affiche des informations d'état, des paramètres et un message-guide d'anomalie de l'interface selon une instruction d'affichage d'interface ; et le module de détection et de régulation de température (400) acquiert la température d'une puce et détermine si la température a dépassé une température de consigne, et effectue un traitement de secours si la température a dépassé une température de consigne. Il existe une plage de détection plus large, un guidage ou un traitement autonome peut être effectué lorsqu'il existe une défaillance, ce qui permet ainsi de résoudre les problèmes selon lesquels le boîtier décodeur existant présente moins de plage de détection et ne peut pas effectuer de détection pendant le fonctionnement ni réaliser de message-guide de défaillance.
