Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The utility model provides a change over switch extension module, electric connection functional module and change over switch, be equipped with the controller in the change over switch, include: a power supply port, a priority determination port, an action port and a communication port which are respectively electrically connected with the controller,
power supply port: comprising a set of power supply ports or a set of low voltage power supply ports and a set of high voltage power supply ports. This is used by supplying power to an external functional module through the port, which may contain one or more voltage levels.
At the same time, the port can also provide external energy to a controller inside the change-over switch.
Priority determination port: the port comprises a plurality of sub-ports, and whether the sub-ports are in the forced interrupt state and the forced interrupt state level is determined by the change of the high level and the low level of each sub-port, so that the sub-ports have definite high-low level states. When an external functional module needs to affect the switching logic inside the switch, the level of each sub-port changes accordingly.
An action port: the interior contains three types of action logic. For the automatic change-over switch, all states are changed around three states of main switch, standby switch and double-division, so that the port is used as an external functional module for informing the change-over switch of specific action commands of an internal controller.
Communication port: the function module is used for sending information of the internal controller of the change-over switch to the outside, and has a function of bidirectional selection for receiving and sending, and the transmitted information is not limited to information such as a power state, a mechanism state and the like, wherein the mechanism state is one of a main switch, a standby switch and a double switch.
When a user needs to change an Automatic Transfer Switch (ATSE) into a Remote Transfer Switch (RTSE), the user only needs to plug in the remote control module at the expansion module.
The remote control module internally comprises a processing unit of the remote control module, and a power supply required by normal work can be obtained through a power supply port, so that the processing unit in the remote control module can receive an external remote control signal.
After a processing unit in the remote control module receives an external remote control signal, the current action port is set to a position where the internal controller of the transfer switch is required to execute the mechanical structure.
Meanwhile, the processing unit in the remote control module can set the sub-ports of the priority determining port to be in different high and low level states to inform the switching switch of the priority of the state which needs to be acted currently by the internal controller of the switching switch, and the same priority definition mechanism is adopted between the internal controller of the switching switch and the processing unit in the remote control module. When the priority received by the internal controller of the transfer switch at the priority determination port is higher than the current execution priority of the internal program of the transfer switch, the priority sent by the internal processing unit of the remote control module through the action port is preferentially executed.
When the priority sent by the processing unit in the remote control module through the action port cannot be executed under some special conditions or the execution is not finished, the internal information of the change-over switch can be read through the communication port to judge the current problem.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
