Abstract

Embodiments of this application disclose an optical bus communication method, including: A first terminal obtains first control information from a controller, where the first control information is generated by the controller and is used to control an execution mechanism to work. The first terminal sends the first control information to a central office over a first section, so that the central office forwards the first control information to a second terminal, where the second terminal is connected to the execution mechanism. The first terminal obtains first state information from the central office, where the first state information is used to record a working state of the execution mechanism, the first state information is information sent by the second terminal to the central office over a second section after the second terminal obtains the first control information, and the first section does not overlap with the second section.

Claims10

Dependent claims

A first terminal, the first terminal comprising:

a memory storing instructions;
and
at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
obtaining a first control information from a controller, the first control information being generated by the controller, the first control information being used to control an execution mechanism to work;
obtaining a first compensation duration from the central office, the first compensation duration being obtained by performing ranging on the first terminal by the central office;
sending, after the first compensation duration, the first control information to a central office over a first section, the central office forwarding the first control information to a second terminal, the second terminal being connected to the execution mechanism;
and
obtaining a first state information from the central office, the first state information being used to record a working state of the execution mechanism, the first state information is sent by the second terminal to the central office over a second section after the second terminal obtains the first control information, and the first section does not overlap with the second section.

5 more elements

A second terminal, the second terminal comprising:

a memory storing instructions;
and
at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
obtaining a second compensation duration and a processing duration from a central office, the second compensation duration being obtained by performing ranging on the second terminal by the central office, and the processing duration is determined by the central office in processing a received downstream message by the second terminal;
and
obtaining first control information from the central office, the first control information being generated by a controller, the first control information being sent by a first terminal to the central office over a first section, and the first terminal is connected to the controller;
sending the first control information to an execution mechanism, so that the execution mechanism works under control of the first control information;
and
sending first state information to the central office over a second section and after the second compensation duration and the processing duration when obtaining the first control information, the first state information being used to record a working state of the execution mechanism, and the first section does not overlap with the second section.

and
at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
obtaining a first control information from a first terminal over a first section, the first control information being generated by a controller and the first control information being used to control an execution mechanism to work, the first terminal being connected to the controller;
obtaining a first compensation duration from the central office, the first compensation duration being obtained by performing ranging on the first terminal by the central office;
sending, after the first compensation duration, the first control information to a second device, the second device being connected to the execution mechanism to enable the second device to send the first control information to the execution mechanism;
obtaining a first state information from a second terminal over a second section, the first state information being used to record a working state of the execution mechanism, and the first section does not overlap with the second section;
and
sending the first state information to the first terminal.
