Background

An RS-232-C port (also known as EIARS-232-C) is the most commonly used serial communication port at present. It was a standard for serial communication that was co-established in 1970 by the american Electronic Industries Association (EIA) in conjunction with bell systems, modem manufacturers, and computer terminal manufacturers. IBM's PC has since simplified RS-232 to a DB-9 connector, becoming a de facto standard.

RS-485 is a standard defined to balance the electrical characteristics of drivers and receivers in digital multipoint systems, which is defined by the telecommunications industry association and the electronics industry consortium.

In an industrial control system, an upper computer of industrial control equipment is required to be connected with a lower computer through communication lines (such as RS-232 and RS-485) so as to realize control communication. In the actual communication process of the industrial control equipment, the situation that only part of the terminals in the communication port are used often exists, and therefore the communication port is not fully utilized.

For example, the RS-232 communication line is nine-core, but only three lines RXD, TXD and GND are generally used in industrial control. Accordingly, only three terminals are used in the communication port, and the remaining six terminals are not used. For another example, the RS-485 communication line under the DB25 standard has twenty-five communication ports, but only three communication ports are actually required.

As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 is a schematic structural diagram of an interposer in an embodiment of the present invention. Referring to fig. 1, the present invention provides an adaptor plate for industrial control equipment, the adaptor plate includes a printed circuit board 100, and the printed circuit board 100 is provided with an upper port and a lower port 200 which are connected to each other; the upper ports include first and second upper ports 300 and 400 of different types, and the lower port 200 has first and second terminals; at least one terminal of the first upper port 300 is connected to a first terminal, and at least one terminal of the second upper port 400 is connected to a second terminal.

Specifically, the utility model provides a control connection in the keysets mainly used industrial control equipment that provides. The interposer body is a printed circuit board 100, a first upper port 300, a second upper port 400 and a lower port 200 are provided in the printed circuit board 100, and both the first upper port 300 and the second upper port 400 are connected to the lower port 200. The lower port 200 is used to connect a lower computer in the industrial control equipment, and the upper port is used to connect an upper computer or a power supply device of the lower computer. More specifically, at least one terminal of the first upper port 300 is connected to a part of the terminals of the lower port 200, and at least one terminal of the second upper port 400 is connected to another part of the terminals of the lower port 200, and the specific connection manner is to use a corresponding port circuit, and the port circuit is also provided in the printed circuit board 100.

Because at least two different types of upper ports are switched to the same lower port 200, the switching board mainly has the function of fully utilizing the corresponding port of the lower computer in the industrial control equipment. For example, in the communication connection between an upper computer and a lower computer of an industrial control device, there are cases where a communication port of a certain communication protocol has a plurality of terminals and only part of the terminals are used in the actual communication process. Therefore, when the upper computer is directly connected with the lower computer through the corresponding communication line, only part of terminals in the corresponding communication port of the lower computer are used, and other terminals are in an idle and wasted state. Through the utility model provides a keysets, during the use with the communication port of host computer earlier with one of them host computer port connection in the keysets, it is interconnect to have some specific terminals between this host computer port and the next port 200, wherein some specific terminals are confirmed according to the actual use condition of terminal in the concrete communication agreement. Meanwhile, another upper port is connected with the rest of the terminals in the lower port 200, and the lower port 200 is connected with the corresponding communication port of the lower computer. Wherein, another host computer port can connect the communication port of other host computers, or connect other types of communication port in the same host computer, can also be the external power source of connection. Therefore, each terminal in the corresponding communication port of the lower computer can be used, and the use efficiency of the communication port of the lower computer is improved. Meanwhile, two different ports are switched to the same communication port of the lower computer through the adapter plate, so that the port connection relation of the lower computer is simplified. For example, a power supply line and a communication line of the lower computer are connected in a communication interface of the lower computer in a switching way through the adapter plate, so that the communication and power supply functions of the lower computer are realized simultaneously, and the power supply line is not required to be additionally connected with other ports of the lower computer to supply power for the lower computer.

The types of the upper ports may be different, such as different port functions, or different port models. For example, the two upper ports may be a combination of a communication port and a power supply port, or a combination of two communication ports of different types.

Illustratively, in a usage scenario in which an upper computer is connected to a lower computer through a first communication protocol (assuming that the first communication protocol port has 9 terminals and only 3 terminals (a, b, c) are used in the scenario), if the upper computer is directly connected to the lower computer through a communication line, only 3 terminals are used in the first communication protocol port in the lower computer, and the remaining 6 terminals are not used. In the adapter board matched with the first communication protocol, the first upper port 300 and the lower port 200 are also first communication protocol ports (respectively used for connecting the first communication protocol ports of the upper computer and the lower computer), and three terminals a, b and c in the two first communication protocol ports of the adapter board are correspondingly connected. Meanwhile, the second upper port 400 (the second upper port 400 may be a power port or a second communication protocol port) is connected to the remaining 6 terminals of the lower port 200. When the first communication protocol port of the lower computer is connected with the lower port 200 of the adapter plate, not only the communication function based on the first communication protocol between the upper computer and the lower computer can be realized, but also the communication function based on the second communication protocol or the power supply function can be realized.

Can know through the explanation of above-mentioned example, the utility model provides a keysets for one of them communication port of host computer in the industrial control equipment not only can acquire the communication function who corresponds with this communication interface itself, through can also acquiring other functions outside this communication function. And then make the communication interface in the lower computer fully utilized, simplified the port connection relation of the lower computer at the same time. The problem that a communication port of industrial control equipment is not fully used in an existing industrial control system is solved.

In some embodiments, the first host port 300 and the second host port 400 are both communication ports.

In this embodiment, the two upper ports are both communication ports. Illustratively, the first upper port 300 may be connected to a first communication protocol port of an upper computer, the second upper port 400 may be connected to a second communication protocol port of the upper computer, and the lower port 200 may be connected to a first communication protocol port of a lower computer. When only part of the terminals in the first communication protocol port are used, the terminals in the lower port 200 that are not used by the first communication protocol can be connected with the second upper port 400, so that the first communication protocol port of the lower computer realizes two communication functions.

Illustratively, the two communication ports are an RS-232 port and an RS-485 port.

More specifically, the first upper port 300 and the second upper port 400 are an RS-232 port and an RS-485 port, respectively. When the upper computer and the lower computer of the industrial control equipment are used for RS-232 communication (the communication line has 9 terminals), only three communication lines of RXD, TXD and GND are generally used. At this time, the RS-232 port in the interposer and the lower port 200 (the lower port 200 in the interposer matching with the RS-232 port is also the RS-232 port) may be connected to the terminals corresponding to the three communication lines RXD, TXD, and GND, and the other terminals in the lower port 200 may be connected to the RS-485 port. For example, the A and B terminals which are commonly seen in the RS-485 port can be connected. Thereby the RS-232 port of the lower computer realizes the RS-232 communication function and the RS-485 function at the same time.

In other embodiments, the first host port 300 is a communication port and the second host port 400 is a power port.

Illustratively, the first upper port 300 may be connected to a first communication protocol port of an upper computer, the second upper port 400 may be connected to an external power source, and the lower port 200 may be connected to a first communication protocol port of a lower computer. When only part of the terminals in the first communication protocol port are used, the terminals in the lower port 200 that are not used by the first communication protocol can be connected with the second upper port 400, so that the first communication protocol port of the lower computer realizes two functions of communication and power supply.

Illustratively, the communication port is an RS-232 port or an RS-485 port.

More specifically, the first upper port 300 may be an RS-232 port or an RS-485 port. When the upper computer and the lower computer of the industrial control equipment are used for RS-232 communication (the communication line has 9 terminals), only three communication lines of RXD, TXD and GND are generally used. At this time, the RS-232 port in the adapter plate and the lower port 200 can be connected with the terminals corresponding to the RXD, the TXD and the GND, and the other terminals in the lower port 200 can be connected with the power supply port, so that the RS-232 port of the lower computer can simultaneously realize the RS-232 communication function and the power supply function. And when the upper computer and the lower computer of the industrial control equipment are communicated to use RS-485 (under the DB25 standard, the RS485 communication line has 25 terminals), only 3 terminals are actually used. At this time, 3 corresponding terminals between the RS-485 port in the adapter plate and the lower port 200 (the lower port 200 in the adapter plate matched with the RS-485 port is also the RS-485 port) can be connected, and other terminals in the lower port 200 are connected with the power supply port, so that the RS-485 port of the lower computer can simultaneously realize the RS-485 communication function and the power supply function.

Specifically, when the interposer is used with RS-232 ports, the first upper port 300 and the first lower port 200 in the interposer are also RS-232 ports. Since only three terminals of the RS-232 ports in the industrial control equipment are generally used, three terminals of the first upper port 300 are connected with three terminals of the lower port 200 in the corresponding adapter board, and the rest terminals of the lower port 200 are connected with the positive and negative terminals of the power supply port.

When the interposer is used with the RS-485 port, the first upper port 300 and the lower port 200 in the interposer are also RS-485 ports. Since only three terminals of the RS-485 port in the industrial control device are generally used, three terminals of the first upper port 300 are connected with three terminals of the lower port 200 in the corresponding adapter board, and the rest terminals of the lower port 200 are connected with the positive and negative terminals of the power supply port.

In this embodiment, a patch panel with three upper ports is provided, wherein the first upper port 300 and the second upper port 400 are communication ports, and the third upper port 500 is a power supply port. The three upper ports are connected with the lower port 200, and when the communication port of the lower computer is connected with the lower port 200 of the adapter plate, two communication functions and a power supply function can be realized at the same time.

Further, in one embodiment, the first host port 300 is an RS-232 port and the second host port 400 is an RS-485 port. Three terminals of the RS-232 port are connected to three first terminals, respectively, and two terminals of the RS-485 port are connected to two second terminals, respectively. The positive terminal and the negative terminal of the power supply port are respectively connected with at least two third terminals.

The technical solution of the present invention is explained by the specific preferred embodiments.

Fig. 3 is a schematic structural diagram of an adapter plate in a preferred embodiment of the present invention. Referring to fig. 3, the interposer in the preferred embodiment includes the pcb 100, and two upper ports and one lower port disposed on the pcb 100, the two upper ports being an upper RS-232 port 310 and a power port 410, respectively, and the lower port being a lower RS-232 port 210.

Generally, the upper computer 610 of the industrial control equipment needs to communicate with the lower computer 620, and when the RS-232 is used, only three communication lines of RXD, TXD and GND are needed. While the lower computer 620 communicating with the lower computer is used, another communication line is generally required to be connected for power supply. The adapter plate in the preferred embodiment can be used for switching the RS-232 communication line and the power supply line to the same lower port.

The communication port of the upper computer 610 is used for connecting with a standard RS-232 port and a connecting line, 9 lines are connected, but only three lines of 2, 3 and 5 terminals play a role, and the three lines are connected into an adapter plate instead of being directly connected with the lower computer 620.

Specifically, only three useful wires, i.e., 2, 3, 5 terminals, are provided in the patch panel to connect the 2, 3, 5 terminals between the upper RS-232 port 310 and the lower RS-232 port 210. Meanwhile, a power supply port 410 is also arranged in the adapter plate and is used for introducing an external power supply and connecting the power supply line to the free 6 terminals of the lower RS-232 port 210. Specifically, the positive terminal of the power port 410 may be connected to the 1, 6, and 7 terminals of the lower RS-232 port 210, and the negative terminal may be connected to the 4, 8, and 9 terminals of the lower RS-232 port 210. Thus, the switched lower RS-232 port 210 has the communication function of 3 ports, and the other 6 ports can supply power to the lower computer 620. Other circuit functions (such as power supply) are realized by utilizing the originally wasted 6 ports, so that a certain part of the lower computer 620 can be saved on the wiring (for example, the original 232 communication line and the original power line are simplified, and communication and power supply can be simultaneously provided for one 232 communication).

It should be noted that the remaining 6 terminals of the RS-232 port are not necessarily used as power supply or all are used as power supply.

Fig. 4 is a schematic structural diagram of an adapter plate in another preferred embodiment of the present invention. Referring to fig. 4, the interposer in the preferred embodiment includes a printed circuit board 100, and three upper ports and one lower port disposed on the printed circuit board 100, where the three upper ports are an upper RS-232 port 310, a power port 410, and an RS-485 port 510, respectively, and the lower port is a lower RS-232 port 210.

Generally, the upper computer 610 of the industrial control equipment needs to communicate with the lower computer 620, and when the RS-232 is used, only three communication lines of RXD, TXD and GND are needed. While the lower computer 620 communicating with the lower computer is used, another communication line is generally required to be connected for power supply. The adapter plate in the preferred embodiment can be used for switching the RS-232 communication line, the power supply line and the RS-485 communication line to the same lower port.

The communication port of host computer 610 sets out, uses standard RS-232 port and connecting wire to connect, and 9 lines all have the connection, but only have three lines of 2, 3, 5 terminals to play a role, insert a keysets rather than direct connection lower computer 620 with it earlier.

Specifically, only three useful wires, i.e., 2, 3, 5 terminals, are provided in the patch panel to connect the 2, 3, 5 terminals between the upper RS-232 port 310 and the lower RS-232 port 210. Meanwhile, a power port 410 is further arranged in the adapter plate and is used for introducing an external power supply 630. Specifically, the positive terminal of the power port 410 may be connected to the 1, 6 terminals of the lower RS-232 port 210, and the negative terminal may be connected to the 4, 9 terminals of the lower RS-232 port 210 and serve as the GND terminal. The 1 and 2 ends of the RS-485 port 510 are connected with the 7 and 8 ends of the lower RS-232 port 210, and the RS-485 port 510 further has a GND end. And the RS-485 port 510 is connected to another upper computer 610 to realize 485 communication between the lower computer 620 and the other upper computer 610.

It should be further explained that the adapter board in the two preferred embodiments mainly aims at a port terminal redundancy scene in 232 communication between the upper computer and the lower computer. The upper computer and the lower computer are connected through RS-232 ports, one upper port of the corresponding adapter plate is the RS-232 port and used for being connected with the upper computer, and the lower port of the corresponding adapter plate is also the RS-232 port and used for being connected with the lower computer. Other functional ports, such as a power port and/or an RS-485 port, may also be provided in the patch panel.

Besides the situation of port terminal redundancy in 232 communication between the upper computer and the lower computer, the RS-485 port also has the problem of port terminal redundancy. The DB25 standard RS-485 communication line has 25 terminals, but only 3 terminals are needed. Therefore, based on the same design principle and thought, a port terminal redundancy scene aiming at 485 communication between the upper computer and the lower computer can be designed. Namely, one upper port in the adapter plate is an RS-485 port and is used for connecting an upper computer, and the lower port is also an RS-485 port and is used for connecting a lower computer. Ports for other functions, such as power ports and/or RS-232 ports, may also be provided in the patch panel.

The features of the above-described embodiments may be combined arbitrarily, and for the sake of brevity, all possible combinations of the features in the above-described embodiments will not be described in detail, but should be construed as being within the scope of the present disclosure unless there is any conflict between such combinations of features.

It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be taken as limiting the present invention, and that suitable modifications and variations of the above embodiments are within the scope of the invention as claimed.
