[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. The described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described in the drawings here can be arranged and designed in various different configurations.
[0042] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0043] In the description of this application, it should be noted that relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.
[0044] In conventional technical solutions, when a first device switches to connect to a different second device, it is necessary to unplug and plug in the connector again, unplug the connector of one second device and plug in the connector of another second device to achieve the switching connection.
[0045] However, the connector may not be designed to be sturdy and may gradually wear out during repeated plugging and unplugging, or age over time, making it prone to problems. Plugging and unplugging operations may also cause consequences such as DC power short circuits, sparks, and burnt connectors.
[0046] To overcome the above problems, please refer to Figure 1The embodiment of the present application provides a signal transfer device, including a socket module 101, a first wiring terminal module 102, a first switch module 103, a first cable 104, a second cable 105 and a first signal plug-in module 106. The connection relationship is as follows:
[0047] The socket module 101 is connected to the first terminal module 102 via the first cable 104, and the first terminal module 102 is connected to the first signal plug-in module 106 via the second cable 105 and the first switch module 103; the socket module 101 is used to connect the first device 107; the first signal plug-in module 106 is used to connect at least two second devices 108.
[0048] The first switch module 103 is used to connect the first device 107 to different second devices 108 in different states. Through the switching state of the first switch module, the first device can be connected to different second devices without repeatedly plugging and unplugging the connection cable of the second device, avoiding problems such as short circuit, sparking, and burning of connectors caused by plugging and unplugging operation errors, which not only saves the time of switching connections, but also enhances safety.
[0049] The second cable 105 may include a plurality of mutually insulated wires wrapped in an insulating jacket, each wire transmitting a signal to a second device 108. For m signals and n second devices 108, the second cable 105 may include at least m×n wires.
[0050] Accordingly, the first terminal module 102 has a plurality of terminals, and the number of the terminals may be consistent with the number of wires of the second cable 105 .
[0051] The first switch module 103 may include multiple switches, the number of which may be the same as the number of the second devices, or the number of which may be redundant, to ensure that each second device has a switch to turn on and off. The socket module 101 may be connected to different wiring terminals by multiple first cables 104 .
[0052] In one embodiment, when different second devices are connected to the first device, some cables do not need to be plugged in and out, and a port of a first device can be connected to multiple second devices at the same time. These cables can be a specific part of the signal line. A port of a first device can send signals to multiple second devices at the same time, and multiple second devices can receive the same signal at the same time. Moreover, the second devices act as receiving ends, and the second devices will not affect each other.
[0053] In this case, it is not necessary to pass all the terminals through the first switch module, such as Figure 2 The signal switching device may further include a first straight cable 109 , a second wiring terminal module 110 and a second signal plug-in module 111 .
[0054] The socket module 101 is connected to the second wiring terminal module 110 through the first cable 104, and the second wiring terminal module 110 is directly connected to the second signal plug-in module 111 through the first straight cable 109; the second signal plug-in module 111 is used to connect at least two second devices 108. Since the first straight cable 109 directly connects the second wiring terminal module 110 and the second signal plug-in module 111 without passing through a switch, this not only saves the number of switches, but also reduces unnecessary switch operations, and can shorten the time for switching connections.
[0055] In one embodiment, two groups of switches may be provided, one group of switches being connected in series in the AC conductor, and the other group of switches being connected in series in the DC conductor, which can well isolate AC and DC, or isolate high voltage and low voltage.
[0056] Reference below Figure 3 The signal transfer device may further include a second switch module 114, a third terminal module 112, a second straight-through cable 113, a third cable 115 and a third signal plug-in module 116. At this time, the first terminal module 102 may be used to connect to AC power, and the third terminal module 112 may be used to connect to DC power.
[0057] Figure 3 The example further includes a second wiring terminal module 110, a first straight cable 109 and a second signal plug-in module 111, and the second wiring terminal module 110, the first straight cable 109 and the second signal plug-in module 111 can also be omitted.
[0058] The second terminal module 110, the first straight cable 109 and the second signal plug-in module 111 can relieve the pressure on the number of wires of the second straight cable 113. If the number of wires included in the second straight cable 113 is insufficient to transmit all signals, a first straight cable 109 can be added to transmit the remaining signals.
[0059] The third wiring terminal module 112 may include a first terminal group 1121 and a second terminal group 1122 ; the third signal plug-in module 116 includes a first plug-in group 1161 and a second plug-in group 1162 ; the first plug-in group 1161 and the second plug-in group 1162 are both used to connect at least two second devices 108 .
[0060] The first terminal group 1121 is directly connected to the first plug-in group 1161 through the second straight-through cable 113, and the second terminal group 1122 is connected to the second plug-in group 1162 through the third cable 115 and the second switch module 114. In this way, the signal that needs to be disconnected can be disconnected by the switch, and the signal end that does not need to be disconnected can be directly connected, which saves the number of switches and the process of switching.
[0061] The second switch module 114 and the first switch module 103 can both be implemented with a miniature circuit breaker to realize the switch function. The miniature circuit breaker also has an overload protection function and disconnects in the event of a short circuit, thereby improving the safety of the circuit.
[0062] The signal switching device is suitable for connecting a generator set and a control panel. The first device 107 can be a generator set, and the second device 108 can be a control panel. One generator set is equipped with four control panels. The connection state of one control panel can be controlled by a set of switches. The first switch module 103 and the second switch module 114 can have four sets of switches.
[0063] The generator set provides the control panel with 3-phase 4-wire generator power supply signal, diesel engine sensor signal, generator voltage regulation signal, diesel engine control signal, battery power supply signal and other unit signals. These signals can be transmitted by different wires, by a cable containing multiple wires or by several cables.
[0064] Combination Figure 3 In the implementation mode, the first terminal module 102 can be connected to the three-phase four-wire AC signal of U, V, W, and N of the generator set, and the second terminal group 1122 can be connected to DC power. The DC power connected to the second terminal group 1122 can be used as the power supply of the control panel.
[0065] Figure 4 A signal transfer device implemented by a miniature circuit breaker is shown, wherein the socket module includes a first socket XS11, a second socket XS12 and a third socket XS13. The first cable includes a unit power cable FJ01, a first signal cable FJ02 and a second signal cable FJ03.
[0066] The first wiring terminal module is the wiring post X01, the second wiring terminal module is the first wiring terminal JX01, and the third wiring terminal module is the second wiring terminal JX02.
[0067] The first switch module includes a first miniature circuit breaker QF01-1, a second miniature circuit breaker QF01-2, a third miniature circuit breaker QF01-3 and a fourth miniature circuit breaker QF01-4. The second switch module includes a fifth miniature circuit breaker QF02-1, a sixth miniature circuit breaker QF02-2, a seventh miniature circuit breaker QF02-3 and an eighth miniature circuit breaker QF02-4.
[0068] The first signal plug-in module includes a first plug-in XS01-1, a second plug-in XS01-2, a third plug-in XS01-3 and a fourth plug-in XS01-4. The second signal plug-in module includes a fifth plug-in XS02-1, a sixth plug-in XS02-2, a seventh plug-in XS02-3 and an eighth plug-in XS02-4. The third signal plug-in module includes a ninth plug-in XS03-1, a tenth plug-in XS03-2, an eleventh plug-in XS03-3 and a twelfth plug-in XS03-4.
[0069] There are two types of second terminal blocks JX02, one is directly connected to the third signal plug-in module through the second straight-through cable, and the other is connected to the third signal plug-in module through the third cable and the miniature circuit breaker of the second switch module.
[0070] The first socket XS11 is connected to the power supply of the unit and is used to transmit three-phase four-wire AC signals of U, V, W, and N. Therefore, it is separated from the first signal cable FJ02 and the second signal cable FJ03 and used as a single path.
[0071] Other unit signals can be divided into two groups, namely the first group of unit control signals and the second group of unit control signals. The second socket XS12 is connected to the first group of unit control signals, and the third socket XS13 is connected to the second group of unit control signals.
[0072] The first plug-in XS01-1, the fifth plug-in XS02-1 and the ninth plug-in XS03-1 are connected to the first control screen, the second plug-in XS01-2, the sixth plug-in XS02-2 and the tenth plug-in XS03-2 are connected to the second control screen, the third plug-in XS01-3, the seventh plug-in XS02-3 and the eleventh plug-in XS03-3 are connected to the third control screen, and the fourth plug-in XS01-4, the eighth plug-in XS02-4 and the twelfth plug-in XS03-4 are connected to the fourth control screen.
[0073] Some control signals can be directly connected to the control panel without passing through the circuit breaker. Multiple control panels can receive the same signal at the same time without affecting each other. Therefore, it can be transmitted to four control panels through the third socket XS13, the second signal cable FJ03, the second terminal JX02, the second straight-through cable, and the third signal plug-in module.
[0074] When the number of wires contained in the second signal cable FJ03 and the second straight-through cable is insufficient to transmit numerous control signals, a second socket XS12, a first signal cable FJ02, a first terminal JX01, a first straight-through cable and a second signal plug-in module may be set so that some control signals are transmitted to the four control panels through the second socket XS12, the first signal cable FJ02, the first terminal JX01, the first straight-through cable and the second signal plug-in module.
[0075] When the number of wires contained in the second signal cable FJ03 and the second straight-through cable is sufficient to transmit numerous control signals, the second socket XS12, the first signal cable FJ02, the first terminal JX01, the first straight-through cable and the second signal plug-in module may be omitted.
[0076] The third socket XS13 also has one way to transmit to four control panels through the fifth miniature circuit breaker QF02-1, the sixth miniature circuit breaker QF02-2, the seventh miniature circuit breaker QF02-3 and the eighth miniature circuit breaker QF02-4, and the third signal plug-in module. This way can be the DC power supply of the four control panels. The AC power supply signal and the DC power supply signal are isolated by the switch, and the AC power supply and DC power supply between the four groups of control panels do not affect each other.
[0077] When a control panel is needed to work, the miniature circuit breaker corresponding to that control panel is turned on, and the miniature circuit breakers corresponding to other control panels are turned off. In this way, other control panels will stop working and will not affect the working control panels. For example, when the first control panel needs to be tested with the unit, the first miniature circuit breaker QF01-1 and the fifth miniature circuit breaker QF02-1 are closed, and the other miniature circuit breakers are turned off. When another control panel needs to be tested with the unit, the same is true. Only the miniature circuit breaker corresponding to the control panel needs to be closed, and the other miniature circuit breakers are turned off, avoiding the possibility of DC power short circuit, sparking, and burning of connectors caused by plugging and unplugging during use.
[0078] The above-described device and system embodiments are merely illustrative, and some or all of the modules may be selected according to actual needs to achieve the purpose of the present embodiment. A person skilled in the art may understand and implement the present embodiment without creative effort.
[0079] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
