As shown in fig. 1, the gateway is connected to two relays through two trunk nodes, so that the gateway can control the relays by sending simple digital signals to the relays.
Example 2
The present embodiment further explains the control flow of the gateway and the actions of the power distribution switch under the control of the gateway:
the system described in this embodiment is shown in fig. 2, and mainly includes three modules: the device comprises a remote control console, an equipment parameter storage and display module and an equipment parameter acquisition and writing module. The remote control console is mainly responsible for daily monitoring of key power distribution parameters and breaker states of the electrical equipment, and can manually or automatically control the power supply of the power distribution system to the equipment through a custom rule; the equipment parameter storage and display module is mainly used for storing and issuing the electric equipment acquisition parameters and the write-in parameter list, analyzing, storing and warehousing the acquired and reported parameters, and simultaneously sending the manual or automatic control signals issued by the console to the equipment parameter acquisition and write-in module through an internal interface after assembling; the equipment parameter acquisition and writing module is responsible for acquiring and reporting key parameters and alarm information of the power distribution equipment, performing writing-on and writing-off operation on a dry contact of a corresponding acquisition gateway according to a control signal issued by an upper layer, then performing writing-off operation within a specified time, and feeding back an operation result to the upper layer.
Based on the above structure, the flow of controlling the power distribution of the electrical device in this embodiment is as follows:
firstly, the on-off of the 7/8 end or the 4/6 end of the control relay is controlled by the on-off of the collection gateway trunk node (as shown in figure 1), so that the on-off of the coil 1 or the coil 2 is controlled, and when the coil is electrified, the switch can be switched off or on under the physical action condition.
And secondly, the monitoring system can access the collected power distribution key parameters and alarm information of various electrical equipment through general protocols (MODBUS, HTTP and the like).
And thirdly, the equipment parameter storage and display module transmits the equipment key parameters, the control parameters and the like to the equipment parameter acquisition and writing module through an internal interface, and the equipment parameter acquisition and writing module acquires and reports the equipment parameters including the equipment power distribution key parameters, the alarm, the breaker state and the like according to the scanning period.

Sixthly, the equipment parameter acquisition writing module performs writing on and off on a dry contact DO1 or DO2 of the acquisition gateway according to the writing parameter list to control the on and off of the switch; because the hardware coil 1 and the coil 2 are burnt and damaged after being electrified for a long time, the electrifying time of the coils needs to be controlled, the write-off operation needs to be sent within the specified time after the acquisition gateway dry node is closed, and the time can be flexibly configured to meet the requirements of different devices.
Based on the power distribution control circuit, the power supply disconnection of the fault power distribution equipment and the power supply disconnection after the equipment fault can be flexibly and remotely controlled through the gateway. Meanwhile, the scheme of the embodiment only needs to add simple relays and electromagnetic coils on the basis of the original power distribution monitoring system, and the interface carries out power distribution remote control through a software interface; in addition, operation and maintenance personnel can select a manual control power distribution system according to actual conditions, and can also judge power distribution key parameters and alarm information of equipment acquired through a gateway according to professional analysis, a preset control rule is added to realize automatic remote control, and rule judging conditions can be flexibly changed according to the actual conditions.
Example 3
The present embodiment further explains the scheme provided by the present invention mainly from the control flow of the gateway: in the embodiment, manual triggering of opening and closing operations is carried out according to self judgment of operation and maintenance personnel; meanwhile, control rules can be customized according to equipment parameters, and if the equipment parameters are in a fault range (the fault range can be determined by a preset threshold), disconnection operation is triggered; if the device parameters return to the normal range, a close operation is triggered.
As shown in fig. 3, the disconnection control process includes the following steps:
1) the circuit breaker is in a closed state under the initial condition;
2) if the manual control is disconnected, jumping to 4);
3) if the manual control is not disconnected, the judgment is continued based on the automatic control rule, and if the equipment is not in the fault range, the process is ended; if the equipment is in the fault range, triggering an automatic control disconnection request, and continuing the process;
4) the device parameter acquisition writing module writes the acquisition gateway dry contact DO1 through an MODBUS TCP protocol according to the write close state request, and returns an error if the write is unsuccessful; the writing success continues the process;
5) when the coil 1 is electrified, the switch is set to the off position under the physical action;
6) and then, in a specified time interval, the equipment parameter acquisition and write-in module writes and disconnects the acquisition gateway dry contact DO1 again, if the writing fails, an error is returned, if the writing succeeds, the coil 1 is powered off, and the whole process is ended.
As shown in fig. 4, the control closing process includes the following steps: 1) the initial breaker is in an off state;
2) if the manual control is closed, skipping to 4);
3) if the manual control is not disconnected, the automatic control rule is continuously judged, and if the equipment is in the fault range, the process is ended; if the equipment is not in the fault range, triggering an automatic control closing request, and continuing the process;
4) the device parameter acquisition writing module writes the acquisition gateway dry contact DO2 closed through an MODBUS TCP protocol according to the write-closed state request, and returns an error if the write-in is unsuccessful; the writing is successful and the process is continued;
5) at the moment, the coil 2 is electrified, and the switch is set to be in a closed position under the physical action;
6) and then, in a specified time interval, the equipment parameter acquisition writing module is used for writing off the acquisition gateway dry contact DO2 again, if the writing fails, an error is returned, if the writing succeeds, the coil 2 is powered off, and the whole process is ended.
