Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote monitoring and control device, and more particularly to a remote monitoring and control device that allows easy operation of control commands on a control console.

FIG. 1 shows a plurality of slave stations 3 (3-n-1 to 3-n-Mu;n
= 1 to N) to one master station 2 (2-1 to 2-N), respectively.
1 shows a system configuration in which N sets of 1-to-M remote monitoring devices controlled via communication lines 4 (4-1 to 4-N) are assembled. The idea of dividing slave stations into several groups and controlling each with one master station is because there is a limit to the number of slave stations that can be controlled by one master station, and if the master station goes down. This is to ensure that the damage does not spread over a wide area when a disaster occurs. In addition, one control console 1 is provided as a man-machine interface for the operator to operate control commands, and one of the switches (SW) array on the panel
An example is shown in FIG. It is assumed that there are control consoles 1-1 to 1-N corresponding to the master stations 2-1 to 2-N. Here, to simplify the explanation, it is assumed that each of the slave stations 3-1-1 to 3NMN corresponds to one selection switch 5-1-1 to 5NMPt, respectively. In addition, each control console 1-1~
Each switch 1-N has one off control switch 6-1 to 6-N and one large control switch 7-1 to 7-N.

A suitable example of applying a control car with such a configuration is in the field of electric railways, where a unit section for feeding electricity is determined and the power is turned on or off depending on the time of day. .

For example, before the departure of the first train, the power is sequentially turned on to the corresponding transport sections, and after the arrival of the last train, the power is sequentially turned off to the corresponding transport sections. According to such seven stems, the number of control points increases as the feeding unit section becomes shorter and as the total line length of the controlled object becomes longer. If one section is defined as one point, the total number of feeder sections over the entire line length is the total number of control points.

Next, a specific operation method on the control console 1 will be explained. One selection switch 5-1~5-N-MN is for position selection, first select this selection switch 5-1-44-+~
Select one out of 5 N MN.

After confirming that the selection is correct, press the OFF execution switch 1 to 6-N or the ON execution switch 7-1 for control execution.
When one of the selection switches to 7-N is pressed, the control command is transmitted to the corresponding slave station.

Here, when there are many control points to be controlled, select the corresponding selection switch 5-1-Sai to 5-N-MN for each control point.
The above operating procedure must be repeated each time, which is very complicated. To solve this problem, select switch 5-
1-Rei ~ 5-N -M Select only the leftmost and rightmost switches you want to select from N, and then press the separately provided multi-selection switch to move the position between the two selected selection switches. Select all the selection switches to
After confirming that the selection is correct, turn off execution switch 6-
It is conceivable to operate the on/off switches 1 to 6-N or the on/off switches 7-1 to 7-N. In this case, if the effective range of the execution switch is limited to the control positions belonging to the corresponding master station, the selection switches 5-1-1 to 5-N-M N
After selecting the appropriate one among them, all of the OFF execution switches 6-1 to 6-N or ON execution switches 7-1 to 7-N of the master station having the selected selection switch must be pressed. For this reason, when there are many master stations 2-1 to 2-N, it is necessary to press the execution switch correspondingly to that number.

Next, in order to solve this drawback, which master station 2-1 to 2-
If the OFF execution switches 6-1 to 6-N and ON execution switches 7-1 to 7-N corresponding to N are also valid for the control positions belonging to all master stations, after selecting a certain selection switch, this If you select another selection switch and press the execution switch while the selection remains in the selected state without canceling the selection, the control data corresponding to the previously selected selection switch will also be transmitted to the slave station. This will cause some inconvenience. When pressing the execution switch, of course, select switch 5-
1-1 to 5N-MN are selected correctly. If there are many master stations 2-1 to 2-N and the length of the control console 1 is long, select switch 5-1-MN is checked. 1-5
-N -M Possibility of not checking the selection status of N,
That is, the possibility of redundant control execution arises.

An object of the present invention is to provide a remote monitoring and control device that can be operated easily and safely from a control console.

A feature of the present invention is that a signal line is provided between adjacent master stations to mutually communicate that the execution switch is pressed,
Each master station pays attention to the selection state of the left and right selection switches of its own selection switch, and only when these switches are in the selected state does the execution switch of the adjacent master station become effective for the own station. It is.

FIG. 3 shows the control console 1 and master station 2 (2-1 to 2-1) related to the present invention.
2-N) is a diagram illustrating an example of the configuration and connection relationship with FIG. FIG. 4 is a diagram showing a specific example circuit configuration of the master station 2 of FIG. 3. In FIG. 3, the disconnected downlink inter-master station communication signal lines 10-1 to 10 (N-1), the incoming downlink inter-master station communication signal uplink inter-master station communication signal line 13-(N-1) are These are signal lines that communicate to each other between stations that the cut-off execution switches 6-1 to 6-N and the large execution switches 7-1 to 7-N have been pressed. Signal lines 8-1 to 8-N and 9-1 to 9-N connect the off execution switches 6-1 to 6-N and the one-person execution switches 7-1 to 7-N and the master station, respectively. In FIG. 4, the left end selection signal line 19 is a signal line that becomes "1" when the leftmost selection switch belonging to the master station 2 is selected, and the right end selection signal line 20 also belongs to the master station 2. This is a signal line that becomes "1" when the rightmost selection switch is selected. The control lock signal line 18 is a signal line that becomes "1" when the corresponding master station detects an abnormality or the like and is in a control lock state. I! In addition, when the signal line 21 is set to "1", a cut control command is sent to the slave station for the selected position in the group, and the line signal line 22 is set to "1".
This is also the signal line through which a large execution command is sent to the slave station for the selected position in that group.

Here, when the off execution switch 6 of the own station is turned on (off execution SW signal line 8 = "ll"), or when the leftmost selection switch is selected (the leftmost selection signal line 192 "1"), the left parent When the station-to-station disconnection execution downlink inter-master station communication signal line 1O-(n-1) becomes "1" or the rightmost selection switch is selected (
When the right end selection signal f;n 2o-41J) is activated from the right master station, the inter-master station communication signal line 12-n becomes "1", the cut-off line signal line 21
becomes "1". Also, the reason why the Daisho row signal line 22 is set to "1" is based on the same idea. However, control lock signal line 1
Assume that 8 is not "1".

In addition, the condition for the disconnect execution downlink inter-master station communication signal line 10-n to output "1" is when the rightmost selection switch of the own station is selected (right selection signal line 2O-41J and , the cut-off execution downlink control signal line is turned on (cut-off execution SW signal line 8 = rlJ), or when the leftmost selection switch of the own station is selected (left-most selection signal line 19 = 41j). 1O-(When n-13 is "1". Large execution downlink inter-master station communication signal line 11-n
The condition for outputting "1" is that the right selection signal line 20 =
[In IJ, whether the large execution switch 7 is turned on (large execution SW signal line 9 = "1") or the left end selection signal line 19-
When it is "1", the large execution downlink control signal line 1l-(n-13 is "1". Also, the large execution uplink communication signal line 12-(n-13 and large execution uplink) The conditions for the inter-master station communication signal line 13-(n-1) to output "1" are as follows:
It corresponds to the large execution downlink inter-master station communication signal line 11-n.

In FIG. 4, 14-1 to 14-6 are contact input filters, 15-1 to 15-4 are output buffers, and 16-
1 to 16-10 are AND gates, and 17-1 to 17-6 are OR gates. Since the operations of these logic circuits themselves are easily understood, their explanation will be omitted.

By exchanging communication signals between the master stations in this way, turning on one execution switch on the control desk will send control commands to the effective range of that execution switch (control commands for the selected position). range) is the master station where the execution switch was pressed and the master station whose left and right selection switches are selected in all the parent stations between the master station where the execution switch was pressed and the master station where the execution switch was pressed. be.

In this way, after selecting the selection switches for the required range section, if you turn on the execution switch of one of the master stations to which those selection switches belong, the operation of the execution switch will be valid for the selection switch of the selected section. Therefore, there is no need to press the execution switch for each master station.

Furthermore, for a master station where the leftmost or rightmost selection switch closest to the pressed side of the execution switch is not selected, the operation of that execution switch is invalid.

Therefore, when pressing the execution switch, it is necessary to check whether the selection switch is correctly selected, of course for the part corresponding to the currently selected master station, but also for the part corresponding to the master station where the execution switch was pressed. It is only necessary to carry out further processing only for the master stations whose left and right selection switches are selected in all master station boundaries between them. Since the execution switch is not valid for the parts corresponding to other master stations, there is no need to check them.

Also, AND gate 16-5 and AND gate 1 in FIG.
Even if we exclude the right selection signal 200 condition in 6-6 and the left selection signal 190 condition in AND gate 16-3 and AND gate 16-4, the effective range when pressing one execution switch on the control desk is Almost the same effect can be expected since the selection switch on the opposite side of the parent station becomes the selected parent station in the parent station whose execution switch is pressed and all the parent station boundaries between the parent station and the parent station.

In addition, except for the condition of the left selection signal 19 in the AND gate 16-1 and the AND gate 16-2, the AND gate 16
-7 and AND gate 16-8, even if you exclude the condition of right selection signal 20, when you press one execution switch on the control desk, the effective range is between the master station where the execution switch was pressed and that master station. In all the parent stations located in the parent station, the selection switch close to the pressed execution switch is selected.

As described above, according to the present invention, when pressing the execution switch for a plurality of consecutive selection switches across a plurality of master stations,
Check the selection status of the selection switch of the master station whose left and right selection switches are selected in all master station boundaries between the relevant master station and the relevant master station, and press one execution switch. This reduces the burden on the control console operator and reduces operational errors.
