Please refer to FIG. 3 for details.

Fig. 3 shows a flowchart of a communication method of a half-duplex communication device in an embodiment of the present invention. Referring to FIG. 3 , the communication method of the half-duplex communication device in the embodiment of the present invention is suitable for adjusting the space occupied by the first storage area and the second memory in the shared storage space during the half-duplex communication process. Specifically, it can be Take the following steps to achieve:

Step S301: Obtain information about the amount of data received by the first port and the second port within a preset time period.

Referring to FIG. 2 , in a specific implementation, the controller 211 is coupled to the shared storage space 212 , and the Ethernet transmitter storage interface 205 , the Ethernet receiver storage interface 206 , the telephone transmission storage interface 209 and the telephone reception storage interface 210 .

Wherein, the Ethernet transmitter storage interface 205 and the Ethernet receiver storage interface 206 are respectively used to generate the read address and the write address of the first storage area, and the telephone transmission storage interface 209 and the telephone reception storage interface 120 are respectively used to generate the second storage area. The read address and write address of the area. When the preset duration is reached, the controller 211 can determine the data stored in the first storage area through the read address and write address of the first storage area generated by the Ethernet transmitter storage interface 205 and the Ethernet receiver storage interface 206 The amount of data stored in the second storage area is determined by sending the read address and the write address of the second storage area generated by the phone sending storage interface 209 and the phone receiving storage interface 210.

In an implementation of the present invention, the preset duration is a communication cycle of the half-duplex communication device, including the cycle of receiving data by the Ethernet and sending data by the telephone port, plus the cycle of receiving data by the phone port and sending data by the Ethernet port . In the communication period, during the period when the Ethernet port receives data, the data received through the Ethernet port will then be transmitted out through the telephone port. Likewise, during the period when the phone port is receiving data, the data received through the phone port is then transmitted out from the Ethernet port. Therefore, the amount of data stored in the first storage area and the second storage area within the preset time period can be used as a measure of the amount of data received by the first port and the second port within the preset time length.

Step S302: Based on the information of the amount of data received by the first port and the second port within a preset time period, adjust the space occupied by the first storage area and the second storage area in the preset shared storage space.

In a specific implementation, when the controller 211 determines the amount of data stored in the first storage area and the second storage area within a preset time period, according to the information on the amount of data received by the first storage area and the second storage area, the shared The space occupied by the first storage area and the second storage area in the storage space 212 is adjusted.

Specifically, the controller 211 can compare the amount of data stored in the first storage area and the second storage area within the corresponding preset time period, and according to the comparison result, allocate more storage space, allocate the remaining storage space in the preset storage space to the storage area with a small amount of data stored. In an embodiment of the present invention, the controller 211 allocates a corresponding proportion of the storage space in the preset storage space to the corresponding storage area according to the ratio of the amount of data stored in the first storage area and the second storage area within the preset time length .

In a specific implementation, the controller 211 can adjust the space occupied by the first storage area and the second storage area in the shared storage space 212 by controlling the space allocation pointer to point to a position in the shared storage space. Wherein, the space allocation pointer corresponding to the first storage area points to the start address of the first storage area in the shared storage space, and the space allocation pointer corresponding to the second storage area points to the start address of the second storage area in the shared storage space.

In the initialization stage of the half-duplex communication device, the first storage area and the second storage area respectively occupy the general storage space of the shared storage space. At this time, the space allocation pointer corresponding to the first storage area points to the zero address of the shared storage space. The space allocation pointer corresponding to the second storage area points to the (k/2-1) address of the shared storage space. Wherein, k represents the storage capacity of the shared storage space.

For example, when the shared storage space has a storage capacity of 1Kb, the first storage area and the first storage area each have a storage space of 512 bits during the initialization phase of the half-duplex communication device. At this time, the allocation pointer corresponding to the first storage area points to the zero address area of the shared storage space, and the space allocation pointer corresponding to the second storage area points to the 512 address of the shared storage space, that is, the storage space corresponding to addresses 0-511 is used as the first In the storage area, the storage space corresponding to addresses 511-2023 is used as the first storage area.

During the working process of the half-duplex communication device, the controller compares the amount of data stored in the first storage area and the second storage area with a preset period of time, and moves the space corresponding to the second storage area according to the comparison result. The storage location pointed to by the pointer is allocated, so that more storage space in the shared storage space is allocated to the first storage area or the second storage area that stores a large amount of data.

It should be pointed out here that when the data stored in the first storage area or the second storage area is zero within the preset time period, all the storage space of the shared storage space will be allocated to the storage area storing the data.
