[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] The utility model discloses an integrated communication cable, such as Figure 1 As shown, it includes a communication adapter board, a cable housing 1, an external interface terminal 2 and a cable 3. The communication adapter board includes multiple chips that convert different communication signals into 485 communication signals, and is used to uniformly condition 485 communication signals, 232 communication signals, TTL communication signals and USB communication signals into 485 communication signals. The cable housing 1 is arranged outside the communication adapter board and wraps the communication adapter board. Since the communication adapter board is arranged inside the cable housing 1, Figure 1 Not shown in the figure, the circuit structure of the communication adapter board is as follows Figure 2 As shown. External interface terminal 2 is located outside the cable housing 1 and connected to the signal input terminal of the communication adapter board, for connecting to various external photovoltaic devices. If the communication adapter board can uniformly condition 485, 232, TTL, and USB signals into 485 signals, the present invention can adapt to external devices using 232, TTL, 485, and USB communication methods. Cable 3 is located outside the cable housing 1 and connected to the signal output terminal of the communication adapter board.

[0028] like Figure 2As shown, the communication adapter board includes a first chip 601, a second chip 602, and a third chip 603. The first chip 601, the second chip 602, and the third chip 603 respectively convert different communication signals into 485 communication signals. The first chip 601, the second chip 602, and the third chip 603 are different chips. The first chip 601 is used to convert TTL communication signals into 485 communication signals, the second chip 602 is used to convert 232 communication signals into 485 communication signals, and the third chip 603 is used to convert USB communication signals into 485 communication signals. The first chip 601, the second chip 602, and the third chip 603 are arranged in parallel. The signal input terminal 604 of the first chip, the signal input terminal 605 of the second chip, and the signal input terminal 606 of the third chip are connected to the external interface terminal 2, and the signal output terminal 607 of the first chip, the signal output terminal 608 of the second chip, and the signal output terminal 609 of the third chip are connected to the cable 3. In this embodiment, the first chip 601 is an AZRS485 chip, the second chip 602 is an SP3220 chip, and the third chip 603 is a CH340E chip. The signal input terminal 604 of the first chip, the signal input terminal 605 of the second chip, and the signal input terminal 606 of the third chip are connected together and connected to the external interface terminal 2 through a transient suppression diode 610.

[0029] In this embodiment, the communication adapter board further includes a through circuit 611. The through circuit 611 is provided between the signal input terminal 604 of the first chip and the signal output terminal 607 of the first chip, or between the signal input terminal 605 of the second chip and the signal output terminal 608 of the second chip, or between the signal input terminal 606 of the third chip and the signal output terminal 609 of the third chip. Figure 2 The figure illustrates a direct-through circuit 611 disposed between the signal input terminal 604 and the signal output terminal 607 of the first chip as an example. When a 485 communication signal is input to the external interface terminal 2, the direct-through circuit 611 is connected; when a non-485 communication signal is input to the external interface terminal 2, the direct-through circuit 611 is disconnected. A resistor 612 is provided on the direct-through circuit 611. The resistor 612 on the receive data line of the direct-through circuit 611 has a low resistance value close to 0 ohms.

[0030] The integrated communication cable in this embodiment further includes a signal output terminal 4, which is connected to the end of the cable 3 away from the communication adapter. The signal output terminal 4 can be a cold-pressed tubular terminal for outputting the unified 485 signal.

[0031] When using the integrated communication cable of the present invention, external photovoltaic devices with different communication methods are connected through external interface terminals 2. The different communication signals of the different photovoltaic devices are uniformly conditioned into 485 communication signals by the communication adapter board within the cable housing 1. The uniformly conditioned 485 communication signals are then output through cable 3 via signal output terminal 4. Stable output is achieved through cable 3, and the length of cable 3 can be adjusted according to site conditions and can be arranged with cable ties 5 to adapt to various communication distances.

[0032] When the communication mode of the connected external photovoltaic device is TTL, the pass-through circuit 611 is disconnected. At this time, the TTL communication signal is input into the communication adapter board through the transient suppression diode 610. The first chip 601 recognizes the TTL communication signal and converts the TTL communication signal into a 485 communication signal. The converted 485 communication signal is input into the cable 3 through the signal output terminal 607 of the first chip, and then output through the signal output terminal 4.

[0033] When the communication mode of the connected external photovoltaic device is 232, the through circuit 611 is disconnected. At this time, the 232 communication signal is input into the communication adapter board through the transient suppression diode 610. The second chip 602 recognizes the 232 communication signal and converts the 232 communication signal into a 485 communication signal. The converted 485 communication signal is input into the cable 3 through the signal output terminal 608 of the second chip, and then output through the signal output terminal 4.

[0034] When the communication mode of the connected external photovoltaic device is USB, the pass-through circuit 611 is disconnected. At this time, the USB communication signal is input into the communication adapter board through the transient suppression diode 610. The third chip 603 recognizes the USB communication signal and converts the USB communication signal into a 485 communication signal. The converted 485 communication signal is input into the cable 3 through the signal output terminal 609 of the third chip, and then output through the signal output terminal 4.

[0035] When the communication mode of the connected external photovoltaic device is 485, the through circuit 611 is connected. At this time, the first chip 601, the second chip 602, and the third chip 603 are in a short-circuited state. The 485 communication signal is directly input into the cable 3 through the through circuit 611 and then output through the signal output terminal 4.

[0036] This utility model uses a communication adapter board to uniformly convert 485, 232, TTL, and USB communication signals into 485 communication signals, thereby achieving compatibility with multiple communication methods and adapting to external photovoltaic devices using various communication methods. Furthermore, the external interface terminals can adapt to multiple interfaces such as USB3.0, USB2.0, DB9, and RJ45, making it compatible with photovoltaic devices of different brands and models using different communication methods, thereby achieving wide application in photovoltaic communication scenarios.

[0037] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
