Embodiment Construction
[0026] Embodiment of power data link transmission method:
[0027] The power data link transmission method proposed in this embodiment is based on figure 1 The power communication system shown includes a control center, several switching devices, and power terminal devices (referred to as terminal devices), and the several switching devices include access switch devices and intermediate switches.
[0028] The terminal equipment is used to collect power service data; the access switch equipment is used to connect with the terminal equipment. Both the access switch equipment and the intermediate switch include a controller, an uplink port and a downlink port. The uplink port of the incoming switch device is connected to the intermediate switch; the control center is connected to the intermediate switch to send the power service data to the control center (that is, the destination end).
[0029] The system realizes the transmission of power service data based on the time-sensiti...

The invention relates to access switch equipment, a control center and a power data link transmission method, and belongs to the technical field of power communication. The transmission method comprises the following steps: sending power service data of power terminal equipment to an access switch, adding time scale information to the power service data by the access switch, and transmitting the powere service data to a destination end through at least two paths formed by a plurality of intermediate switches; calculating transmission durations of different paths according to the received powerservice data with the time scale information, and taking the path with the shortest transmission duration as an optimal path; and configuring each intermediate switch according to the optimal path, realizing configuration of the optimal path, and controlling the power business data to be transmitted according to the configured optimal path. According to the invention, the power service data is transmitted through the optimal path, the communication channel is optimized, the requirement of reliable communication is met, and the influence of detection and broadcasting on the link can be reduced.
Description
technical field [0001] The invention relates to an access switch device, a control center and a power data link transmission method, and belongs to the technical field of power communication. Background technique [0002] Traditional asynchronous Ethernet works in an asynchronous manner, and any device in the network can send data at any time, so the transmission time of data is neither accurate nor uncertain. In order to promote Ethernet to network scenarios that require low latency and deterministic latency, such as industry and vehicles, IEEE has formulated the TSN (Time Sensitive Networking) protocol suite. [0003] Time Sensitive Networking (TSN) is a new-generation network standard based on Ethernet, which has functions such as time synchronization and delay guarantee to ensure real-time performance. TSN actually refers to a set of "sub-standards" formulated based on specific application requirements under the framework of the IEEE802.1 standard, aiming to establish a...
