Abstract
(EN) Disclosed are an adaptive adjustment control method and apparatus, a gateway terminal, and a storage medium. The adaptive adjustment control method comprises: acquiring message parameters of a server and load state data of a bus, wherein the message parameters comprise an initial message ID, a message delay time allowable value corresponding to the initial message ID, and an optimized message ID corresponding to the initial message ID; calculating a message delay time estimated value according to the load state data and the initial message ID; and according to the message delay time estimated value and the message delay time allowable value, selecting the initial message ID or the optimized message ID to perform bus communication, so that the priority of a message is adaptively adjusted, thereby reducing the risk of message delay or frame loss, and improving the real-time performance and reliability of network communication.
(FR) Un appareil et un procédé de commande de réglage adaptatif, un terminal de passerelle, et un support de stockage sont divulgués. Le procédé de commande de réglage adaptatif consiste : à acquérir des paramètres de message d'un serveur et des données d'état de charge d'un bus, les paramètres de message comprenant un ID de message initial, une valeur admissible de temps de retard de message correspondant à l'ID de message initial, et un ID de message optimisé correspondant à l'ID de message initial ; à calculer une valeur estimée de temps de retard de message en fonction des données d'état de charge et de l'ID de message initial ; et en fonction de la valeur estimée de temps de retard de message et de la valeur admissible de temps de retard de message, à sélectionner l'ID de message initial ou l'ID de message optimisé pour effectuer une communication par bus, de sorte que la priorité d'un message est réglée de manière adaptative, ce qui permet de réduire le risque de retard de message ou de perte de trame, et d'améliorer les performances en temps réel et la fiabilité de la communication réseau.
(ZH) 本申请公开了一种自适应调节控制方法及装置、网关终端及存储介质,其中,所述自适应调节控制方法包括获取服务器的报文参数以及总线的负载状态数据,所述报文参数包括报文初始ID、与所述报文初始ID对应的报文延时时间容许值以及与所述报文初始ID对应的报文优化ID,根据所述负载状态数据以及所述报文初始ID计算报文延时时间预估值,根据所述报文延时时间预估值以及所述报文延时时间容许值,选取所述报文初始ID或者所述报文优化ID进行总线通讯,如此,自适应调整报文的优先级,减少了报文延时或者丢帧的风险,提高了网络通讯的实时性和可靠性。
