Address, substation specifies testing agency 53 that the data value of the second management control data IDXo and address, substation self is compared, and when result is consistent, in response to the first management control data ISTo, by predetermined data, gives coding mechanism 56.When interlocking abnormal data for demonstration detects, the first management control data ISTo gives coding mechanism 56 by interlocking anomaly detection signal.
, in response to the condition substation data of inputting from condition substation Data Detection mechanism 49 and the substation its data inputted from substation its data testing agency 47, carry out to the output of coding mechanism 56 in logic judgement loop 55.Particularly, when condition substation data and substation self data is similarly " 1 ", carry out the abnormal output of display and interlock (A shown in Fig. 6), in addition show normal output (N shown in Fig. 6).
The interlocking anomaly detection signal that coding mechanism 56 specifies testing agency 53 to send here in response to address, substation, by judging that from logic the demonstration of exporting in loop 55 is normal and interlock abnormal information, be converted to predetermined coded data, as the second management, monitor that data ID Xi delivers to management and monitors data transport mechanisms 45.
Now, the second management of delivering to management intermediate data connecting gear 45 monitors data ID Xi, shows normally or interlock abnormal coded data to adopt " 0 " value in addition.Therefore what as management, monitor that data transmit is " 0 " data in addition.I.e. management can say from inputting the information of exporting substation 7 and by common data signal line DP, DP, not be sent to the state of main website while monitoring data for " 0 ".Thereby be now judged as the broken string of common data signal line DP, DN side.
Although the first management monitors that data STi is not used in the present embodiment in addition, when needing the second management to monitor the further differentiation of data ID Xi, just can use this first management intermediate data Sti.
Then explanation is about the step of the interlocking method for detecting abnormality in the control supervisory signal transfer system of foregoing structure.
Control part 1 is in the sequential of suitable setting, or via any input indication of user, and the management that is used to indicate the interlocking abnormality detection of efferent 8 is controlled to parallel data 14, exports main website 2 to.Main website 2 outputs that receive these data require the first management control data ISTo of interlocking abnormality detection and specify second management of in the data group that is stored in IDX address form to monitor data ID Xo.In the management data portion 22 of main website 2, made as shown in Figure 9 IDX address date form in addition, each that monitors along with initial signal ST and control subsequently that data area and management data area form transmits circulation, according to the second management control data IXDo to whole inputs substation 7 good front leading address of assignment of allocation successively.
The data of the IDX address form carrying out according to the second management control data IDXo are appointed as according to form numbering and are carried out.First the index address data (#ad0) of form numbering 1 are selected and export as the second management control data IDXo.And along with each transmits circulation, successively change to substation grouped data and become " 1 " each form numbering front address date of correspondence.But with the order of the data of the second management control data IDXo assigned I DX address form unrestricted, for example also can be according to the priority of coming according to function.
Output substation 6, when the second management control data IDXo and substation self address is consistent, according to the output that certainly interlocks abnormal detection mechanism, is overlapped in management by management supervisory signal abnormal by display and interlock or that normal data forms and monitors data area.The main website 2 that receives this delivers to control part 1 from managing acquisition management supervision data in supervisory signal.
In control part 1, according to the second management, monitor the content of parallel data 17, carry out predetermined processing.If particularly the second management monitors that parallel data 17 shows abnormal person, execute exception represents.Management monitors when data are " 0 " again, is judged as the broken string of common data signal line DP, DN, carries out the demonstration of content like this.
Through the control part 1 of above step, can grasp corresponding output substation 6 efferent 8 each whether have and connect abnormal or interlock abnormal situation.
Suitable change can be done by control part side with reference to address RADR and data indicated value ID in import and export designated value RD, condition substation in addition.Under this situation, by show change import and export designated value RD, condition substation with reference to address RADR or the data of data indicated value ID and import and export designated value RD after changing, condition substation is with reference to address RADR or the data of data indicated value ID are overlapped in management control data region, in input substation, 7 sides capture this bit.
This controls in supervisory signal transfer system, except interlocking abnormal detection, and can monitor the data of appointment.Under this situation, be arranged at gateway shown in dotted lines in Figure 7 mechanism 62, when 62 inputs of Dui Ci gateway mechanism become the data 63 of monitoring target, from address, substation, specify testing agency's 53 output supervisory signals.And by input monitor command data are sent to corresponding output substation 6 as the first management control data ISTo from main website 2, in appointed output substation 6, Monitoring Data 63 will monitor that by management data transport mechanisms 45 monitors that as management data export, and therefore control part 1 side can be grasped from gateway mechanism 62.
