According to a first aspect of an embodiment of the present invention, it relates to a junction box, and Fig. 1 is a schematic diagram showing the connection relationship between modules in the junction box according to an exemplary embodiment. Exemplarily, the junction box may be a photovoltaic module junction box respectively connected to the input and output terminals of the photovoltaic power generation unit. As shown in FIG. 1 , the junction box includes a control module, an acquisition module, a processing module and a communication module, wherein the control module is connected with the acquisition module, the processing module and the communication module. Here, the junction box may include a housing, and the control module, acquisition module, processing module and communication module may be hardware units located on the housing or built in the housing.

Here, the terminal device may be a smartphone installed with an application program, or a computer, etc., and a junction box record table is stored in the terminal device, and the junction box record table records identification information of a junction box that needs to establish a connection with the terminal device. Here, the identification information is used to distinguish each junction box, for example, the identification information may be a physical address of the junction box or the like. The group of junction boxes can be multiple junction boxes in the same group, or junction boxes belonging to multiple groups. The group can be established according to the location area where the photovoltaic power generation unit connected to each junction box is located. For example, the first group may include identification information of junction boxes connected to photovoltaic power generation units located in the first area, and the second group may include identification information of junction boxes connected to photovoltaic power generation units located in the second area.

In step 12, a network access request message is sent to each junction box in the group of junction boxes according to the identification information.

Here, the terminal device may sequentially send a network access request message to each junction box in the group of junction boxes, so as to control each junction box to establish a connection with itself. Taking the group of junction boxes including the first group and the second group as an example, and each group includes multiple junction boxes, the terminal device may first send network access request messages to each junction box in the first group in sequence, and then, The network access request messages are sequentially sent to each junction box in the second group.

In step 14, a response message sent by the first junction box in the group of junction boxes is received, and a connection is established with the first junction box.

In step 16, a second junction box in the group of junction boxes that fails to connect to the terminal device is determined.

Here, in the process of connecting a terminal device to multiple junction boxes, some junction boxes may not be able to receive the network access request message sent by the terminal device, or the terminal device may not be able to receive the In the case of response messages sent by some junction boxes, the network access request message sent by the terminal device cannot be received, and the junction box whose sent response message is not received by the terminal device cannot establish a connection with the terminal device, that is, connect to the terminal device fail. Here, in order to confirm the connection between each junction box and itself, the terminal device needs to filter out the second identification information of junction boxes that have not established a connection with itself from the record table according to the record table stored by itself and the received response message, so as to Reconnect with the selected junction box.

In step 18, each of the first junction boxes is controlled to be connected to the second junction box, until each of the second junction boxes is connected to one of the first junction boxes, or each of the When none of the second junction boxes establishes a connection with any of the first junction boxes, the networking ends.

For example, the terminal device forms a network with junction box a, junction box b, junction box c, junction box d, junction box e, and junction box f. After junction boxes a and b are directly connected to the terminal device, the terminal device First, control junction box a to connect with junction boxes c, d, e, and f respectively. When junction box c establishes a connection with junction box a, and junction boxes d, e, f fail to connect with junction box a, the terminal device connects to junction box a is controlled so that junction box a is connected to junction boxes d, e, and f through junction box c; when junction box a fails to connect to junction boxes c, d, e, and f, junction box b is controlled in the same way Connect with junction boxes c, d, e, f. For example, the control order of the terminal equipment to the junction boxes a and b may be performed according to the arrangement order of the junction boxes a and b in the junction box record table, or may be performed in other orders.

Here, when the junction box that fails to connect to the terminal equipment establishes a connection with the terminal equipment through the junction box that has established a connection with the terminal equipment, or the junction box that fails to connect to the terminal equipment cannot pass through the junction box that has established a connection with the terminal equipment. When establishing a connection with the terminal device, the terminal device can end the networking. Continuing with the above example, when connection boxes c, d, e, f are connected to terminal box a, or connection boxes c, d, e, f are connected to terminal box b, it means that all the terminal boxes have been connected to the terminal equipment The connection is established, at this time, the terminal equipment can end the networking; and when the junction boxes a and b fail to connect with the junction boxes c, d, e, and f, it means that the junction boxes c, d, e, and f can neither pass through the connection with the junction box The connection between junction box a and terminal equipment cannot be established through connection with junction box b. At this time, the terminal equipment can determine that junction boxes c, d, e, and f are faulty, and can end the networking.

Here, in the process of networking between the terminal device and multiple junction boxes, the terminal device controls the connection between the junction box that has established a connection with itself and the junction box that has failed to connect to itself, so that the junction box that has established a connection with itself can be used as The repeater, in this way, can avoid the problem of being unable to connect due to the too far distance between the junction box and the terminal equipment, and improves the effectiveness of networking between multiple junction boxes and terminal equipment; When all need to be directly connected to the terminal equipment, it is easy to cause serious network packet loss, and it also avoids that some junction boxes cannot establish a connection with the terminal equipment due to serious packet loss, or the junction box that has established a connection with the terminal equipment is easy to drop.

Whether there is a possible faulty junction box in boxes c, d, e, f, so as to prompt the user of the possible faulty junction box. For example, when junction box a establishes connection with junction boxes c and d but fails to connect with junction boxes e and f, and the terminal equipment controls junction box a to connect to junction box e through junction box c, when the terminal equipment connects from junction box When box a receives the connection success message sent by junction box c, it compares the identification information of junction box e included only in the connection success message with the identification information of junction boxes e and f, and determines that it is not included in the connection success message. The identification information of the junction box f in the success message; and display the identification information of the junction box f on the display screen of the terminal device to prompt the user that the junction box f cannot be connected, and the junction box f may be faulty. In this way, the user can know the networking status of each junction box in time, and can perform fault detection or repair on the junction box that may fail in time, thereby improving user experience.

In an embodiment, step 18 in the above junction box networking method may include the following steps:

In step B1, the identification information of the second junction box is sequentially sent to each first junction box until a first connection success message sent by the first junction box is received, and the first connection success message includes establishing a connection with the first junction box The identification information of the connected third junction box, where the third junction box includes a junction box in the second receiving box that establishes a connection with the first junction box, and the third junction box includes all the second junction boxes.
