Embodiment Construction

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Specifically, as figure 2 As shown, the MOST network interface circuit provided by the embodiment of the present invention includes: a MOST controller (INIC) 201, a LIN transceiver 202, an external host controller (EHC) 203 connected to the LIN transceiver 202, and an external host control The first power conversion module 204 connected to the device 203 and the MOST controller 201; the external host controller remains in the no...

Abstract

The invention discloses a MOST network interface circuit and a corresponding MOST network wake-up method, which receives a pulse signal through an independent LIN transceiver and sends it to an external host controller, and the external host controller judges whether the pulse signal is an ECL wake-up signal, If so, generate an enable signal to enable the first power conversion module to supply power to the MOST controller, thereby realizing the ECL wake-up function of the MOST network; that is, the external host controller corresponding to the MOST network slave node is no longer connected to the MOST control The node is powered off synchronously, but remains in the normal power mode. When other networks need to transmit data, the node can also be woken up. Compared with the prior art, the present invention not only ensures that other network data can still be received through the interface circuit in the dormant state of the MOST network, but also avoids the redundant problems of power detection and management functions, and reduces the cost of the ECU.

Description

technical field [0001] The present invention relates to the technical field of MOST (Media Oriented System Transport, media-oriented system transmission) network interface circuit, in particular to a MOST network interface circuit and a MOST network state control method. Background technique [0002] The MOST network interface circuit is an interface circuit for realizing MOST network communication in an ECU (Electronic Control Unit, electronic control unit) with a MOST node. like figure 1 As shown, the existing MOST network interface circuit mainly includes: power conversion module 101, MOST controller (INIC, integrated network interface controller, integrated network interface controller) 102, power management chip (PMIC, power management unit) 103 and external A host controller (EHC, External Host Controller) 104 ; wherein, the MOST controller 102 is connected to the MOST network through a physical layer interface 105 . figure 1 The thick solid line in the figure is the...
