Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
The protection supervisory equipment of the present embodiment includes CPU and at least two for realizing the order circuit of different communication stipulations conversion; each order circuit is all connected with CPU; at least including a communication protocol modular converter in each order circuit, each communication protocol modular converter correspondence is connected to a communication interface.
As shown in Figure 1; the protection supervisory equipment of the present embodiment on existing protection supervisory equipment and meter contact to order circuit upgrading; multiplex communication loop is expanded to by single order circuit; and often road order circuit all supports communication protocol translation function; namely it is provided with the communication protocol modular converter with communication protocol translation function, original simplex is expanded into 4 road independent communication.Wherein the priority of order circuit is otherwise varied, and 1 tunnel is the highest, and 4 roads are minimum, each order circuit can configure different communication protocol modular converters, generally being defaulted as IEC103 stipulations or IEC61850 stipulations, acquiescence is supported to send the data such as measurement, switching value, and distant control function is optional.
Order circuit 1 is major loop, according to actual needs, other communication cables can arbitrarily be connected on other order circuits, all order circuits are different according to backstage, communication protocol modular converter may be configured as RS485 analog-to-digital conversion module, at least one in network communication module or photoelectric conversion module, communication interface is corresponding in turn to and is set to RS485 interface, network interface or light mouth, all order circuits all upload remote measurement to backstage, remote signals (sends simultaneously, stipulations are optional), acquiescence order circuit 1 can send remote signal by backstage to device, control relay outlet transmission, thus controlling chopper, electric bell electric whistle etc. carries out action.If special circumstances need other order circuits to be remotely controlled operation, as configured in protection device software, to support distant control function.
Each order circuit is provided with the time delay determination module that the remote signal whether received with other order circuits for detecting received remote signal is conflicted.The operation principle of time delay determination module is: after such as order circuit 2 receives remote signal, the time delay determination module delayed time judges whether conflict, namely compliance contrast is carried out with device standing state and order circuit 1 control signal, if conflicting with order circuit 1, then device is not processed the remote signal of order circuit 2 and is alerted by device, deliver newspaper on all order circuits warning message, it is simple to operator on duty checks problem.If not conflicting, processing this remote signal, controlling relay outlet transmission.
The order circuit delay decision time is extended to loop 4 successively by loop 2, it is determined that rule is incremented by successively, as communication loop 3, it is determined that rule is: carry out compliance contrast with device standing state and order circuit 1 and 2 control signal.
Generally distant control function is provided only to transformation and distribution system, PLC control system, is not applied to energy efficiency management system or other management systems.There is transformation and distribution system at general scene; realize remotely checking and controlling; indivedual industry spot are except transformation and distribution system; also has PLC control system simultaneously; PLC major control equipment is powered, it is achieved manufacture automatic control, thus has two systems that the remotely control of protection supervisory equipment has been had demand; by configuring distant control function, it is achieved different system controls different chopper to realize difference in functionality (transformation and distribution system is the most powerful).Water, electricity and gas signal is accessed by energy efficiency management system, has coincidence also to have from transformation and distribution system different, and protection supervisory equipment mainly provides it energy information, it is not necessary to provide long-range remote control function.
The communication protocol modular converter with communication protocol translation function is the stipulations modular converter commonly used in prior art, no longer elaborates the principle of stipulations conversion here.
The communication interface of the present embodiment can be configured to serial line interface, Ethernet interface, optical fiber interface etc., it is achieved communication function high ductibility.
As other embodiments, utilized chip IMAX283/287 or STM32F407 arranges 6 road order circuits.
