Embodiment 1

[0070] See image 3 , Which shows that an embodiment of the present invention provides a frame flow control method, and the method may include:

[0071] S101. Determine whether the station has sent / received data. If the station has sent / received data, perform steps S102 and S103; if the station does not send / receive data, perform steps S106 to S108.

[0072] S102. If the site has sent / received data, acquire source address / destination address information of the sent / received data.

[0073] Understandably, if the site needs to send / receive data, it needs to obtain the source address / destination address information of the data to be sent / received to send or receive the data.

[0074] S103. According to the source address / destination address information, it is judged whether the transmission link has been established through the sending / receiving frame stream. If it is judged that the transmission link has been established through the sending / receiving frame stream, steps S104 and S105 are...

Embodiment 2

[0097] See Figure 4 , Which shows that an embodiment of the present invention provides a frame flow control method, and the method may include:

[0098] S201: When it is determined that the station has no data transmission, check the timer count of the sending / receiving frame stream in the station, and release the sending / receiving frame stream whose timer count expires.

[0099] See Figure 5 , Specifically, step S201 includes steps S2011 and S2012:

[0100] S2011: When it is determined that the station has no data transmission, check the timer count of the sending / receiving frame stream, and obtain the updated timer count.

[0101] Understandably, when the station has no data to transmit, it considers releasing its sending / receiving frame stream to release the occupation. The release of the transmit / receive frame stream is judged based on whether the timer count of the transmit / receive frame expires, so first update the timer count of the transmit / receive frame stream to determine ...

Embodiment 3

[0130] See Picture 10 , Which shows that an embodiment of the present invention provides a frame flow control method, which is used to count through a frame flow timer to realize asynchronous release of the frame flow between the first station and the second station. The method may include:

[0131] S301: The first station sends data to the second station by sending the frame stream, and resets the timer count of the sending frame stream.

[0132] It should be noted that when the first station and the second station perform data transmission, the first station sends data to the second station by sending a frame stream. At this time, the sending frame stream of the first station and the receiving frame stream of the second station establish a data transmission link so that data can be transmitted between the two stations.

[0133] A timer is set when the first station creates the sending frame stream. Whenever there is data to send, the timer for sending the frame stream is reset to ...

Abstract

The embodiment of the invention discloses a frame flow control method. The method comprises the following steps: when determining that a site does not have data transmission, checking the count of a timer for sent / received frame flows at the site, and releasing the sent / received frame flows of which the count of the timer is expired; and when determining that the site has data transmission and idle docking frame flows are available in the site, establishing a data transmission link by using the idle docking frame flows to transmit data. The embodiment of the invention also discloses a frame flow control device at the same time.

Description

Technical field [0001] The present invention relates to the technical field of power line communication, in particular to a frame flow control method and device. Background technique [0002] The power line communication network generally adopts the tree topological structure. There is a continuous data flow between the two sites (respectively the sending site and the receiving site) of the parent-child node relationship. The data stream buffer is stored on the sending / receiving site, and the data structure for managing the data stream buffer is a frame stream. A logical data transmission link is formed between the sending frame stream and the receiving frame stream. Each site maintains data communication with other sites directly adjacent to the network topology. In order to realize the synchronization of sending and receiving data between the stations, some commands and responses must be used to coordinate the data transmission between the sending / receiving frame streams of ...
