Abstract: Embodiments of this application disclose a control method, a parameter reading method, a related device, and an industrial network. In the method, a control frame carrying a control command is used, and the control frame carries a small quantity of overhead fields, to increase a transmission speed of the control command. The method in embodiments of this application includes: A first network terminal first receives a first control frame from a control device, where the first control frame carries N control commands, the N control commands are used to control N control objects of at least one industrial device, locations of the N control commands in the first control frame and information about the N control objects meet a first correspondence, and N is a positive integer; then determines, based on the locations of the N control commands in the first control frame and the first correspondence, the information about the control objects respectively corresponding to the N control commands; and finally controls the N control objects based on the N control commands and the information about the control objects corresponding to the N control commands.

Abstract: This application provides a head-up display apparatus (200) and method. The head-up display apparatus (200) includes: a visual positioning unit (210), configured to: obtain line-of-sight information of a user, and determine a target display area based on the line-of-sight information, where the target display area is a sub-area of an overall display area corresponding to an image display unit (240); an image determining unit (220), configured to determine an image of target content in the target display area, where the target content is content corresponding to the target display area in to-be-displayed content of the overall display area; an image control unit (230), configured to adjust a light field to generate a real image of the target content in the target display area based on the image of the target content; the image display unit (240), configured to display the real image of the target content; and an optical unit (250), configured to form a light beam based on the real image of the target content, to generate a virtual image of the target content. The head-up display apparatus and method can reduce power consumption of the head-up display apparatus (200), prolong a service life of a display element, and enable a user to obtain a good visual effect, thereby helping improve driving safety.

Abstract: The present invention discloses a protection switching method and a node. The method includes: receiving, by an intermediate node, a first protection switching request message sent by an upstream neighboring node, where the first protection switching request message is used to request to activate a first protection path, and the intermediate node is a node on the first protection path; determining, by the intermediate node, that the first protection path needs to occupy N1 timeslots, and selecting a first group of timeslots for the first protection path from N2 available timeslots in a preset order, where a timeslot quantity of the first group of timeslots is N1, the N2 available timeslots are available timeslots included in a link between the intermediate node and a downstream neighboring node, and N2 is greater than or equal to N1; and sending, by the intermediate node, a second protection switching request message to the downstream neighboring node, where the second protection switching request message is used to request the downstream neighboring node to complete a cross-connection, on the first protection path, between the downstream neighboring node and the intermediate node based on the first group of timeslots. Use of the present invention may improve timeslot resource utilization.
