2. Description of the Related Art An electronic interlocking device comprehensively controls the entire railroad equipment such as a station yard or a set unit, and an electronic railroad crossing control device controls the crossing of railroad crossings in accordance with the operation of the electronic interlocking device. It controls the necessity. In the electronic interlocking device, it may be necessary to temporarily switch the content or unit of the controlled object. For example, there is a case where the setting is switched between single-track operation and double-track operation for convenience of construction, and when the operation failure or some need arises, the control target is switched to a predetermined railway equipment switching unit. And
Even in the electronic railroad crossing control device, it is necessary to switch the operation according to this switching.

In the conventional electronic interlocking device and electronic railroad crossing control device, interlocking logic storage means in which railroad device switching interlocking logic corresponding to the railroad device switching unit is written is manufactured in advance for each railroad device switching unit. In accordance with the necessity of switching the single-rail operation setting or the double-rail operation setting, which is the railway equipment switching unit, and the need for switching of other railway equipment switching units, the interlocking logical storage means corresponding to the corresponding railway equipment switching unit is provided. The switching of the controlled object is executed by the switching, and in the electronic level crossing control device, the part for switching the level crossing control logic according to the switching of the interlocking logic and the information input different from the interlocking logic are independently switched. It has become.

Specifically, in the electronic interlocking device, as interlocking logic storage means, ROMs, which are interlocking logic storage means for each interlocking logic according to the railway equipment switching unit, are respectively prepared, and a single line as the railroad equipment switching unit. When it is necessary to switch the operation setting or the double-track operation setting, or when it is necessary to switch the railway equipment switching unit, the interlocking logical storage means (RO
M) The switching is performed by manually inserting and removing the device itself, and the electronic level crossing control device changes the output condition from the electronic interlocking device each time, so that the ROM is replaced and the relay logic is changed. Alternatively, switching is executed by replacing the crossing control logic storage means (ROM or the like).

[0005]

However, in such a conventional electronic railroad crossing control device, the logical storage means (ROM, etc.) is replaced manually when the output condition from the electronic interlocking device is changed. Since the switching is executed by inserting and removing it, there is a possibility that an error may occur during the replacement work or a selection error may occur. For this reason, a level crossing control logic confirmation test and a connection test with a relay logic are required for each replacement, which is troublesome, time consuming, labor-intensive, and not only complicated but also enormous manpower is required, resulting in high cost. was there.

Further, since the interlocking and crossing control logics are switched by manually inserting / removing the interlocking logic storage means itself, the number of man-hours is large even when the replacement work time and the replacement work personnel are required. Prevent cost reduction,
There was a problem of delaying rationalization.

The present invention has been made by paying attention to such a conventional problem, and it is possible to switch the level crossing control logic without inserting / removing the logic storage means (ROM or the like). It is an object of the present invention to provide an electronic level crossing control device that does not require a level crossing control logic confirmation test, reduces cost, and improves safety.

Becomes

FIG. 3A shows a state in which the relationship between the localization and the inversion (that is, the complement relationship) in the relay switch is linked to the relationship between the mode selection logic value 13a and the complement mode selection logic value 13b. For convenience, the NOT logical symbol is used for the expression, but the present invention is not limited to this.
It suffices if the complement relation in logical operation can be expressed.

In FIG. 3B, switching of three railroad lines (that is, a switching 1 line, a switching 2 line, and a switching 3 line) is shown as an example. Further, the input interlocking logic mode 12 [FA of the first relay switch, BA of the first relay switch, F of the second relay switch is input.
A, BA of the second relay switch], the mode selection logic value 13a is shown.

For example, interlocking logic mode 12 [FA of the first relay switch, BA of the first relay switch, FA of the second relay switch, B of the second relay switch
A], interlocking logic mode 12 [FA = ON of first relay switch, BA = OF of first relay switch]

For exactly the same reason, the mode selection logic value 13
The complement mode selection logic value 13b, which has a complement relationship with a and the binary logic, is [OFF, ON, OFF, ON].

The interlocking logical mode checking means 15 selects the mode selection logical value 13a [ST1R, ST1BPR, ST2R,
[ST2BPR] and complement mode selection logic value 13b [NOT
(ST1R), NOT (ST1BPR), NOT (ST
2R), NOT (ST2BPR)] at predetermined timing 14.

Further, the interlocking logical mode checking means 15 reads the read mode selection logical value 13a [ST1R, ST1B.

Of the binary logical complement relation (for example, NOT (A) with respect to the logical value A) is checked, and when the logical complementary relation is established, the interlocking logic mode switching signal 15a is generated, When the above complement relation is not established, the interlocking logical mode switching stop signal 15b is generated.

Further, the interlocking logical mode checking means 15 can receive the predetermined timing 14 from a railway line switching system (not shown) or the like. As shown in FIG. 3C, the predetermined timing 14 means the mode selection logic value 13a [ST
1R, ST1BPR, ST2R, ST2BPR] and complement mode selection logic value 13b [NOT (ST1R), NOT
(ST1BPR), NOT (ST2R), NOT (ST
2BPR)] is executed and the interlocking logical mode switching signal 15a is generated as a result, and the electronic interlocking device 10 is activated for switching the railway line. The predetermined timing 14 is not particularly limited to this, and any timing can be selected.

Further, the interlocking logical mode checking means 15 can be conditioned on producing the interlocking logical mode switching signal only when the power is turned on, whereby the electronic interlocking device 10 is powered on. It is possible to prevent accidents such as accidental switching when the user is operating.

By checking the logical complement relationship between the read mode selection logic value 13a and the complement mode selection logic value 13b, an electronic interlocking device can be used to switch rail lines with high fail-safety and reliability. It can be realized in 10.

The storage area in the ROM is subjected to predetermined addressing, and the railroad equipment switching interlocking logic 11a corresponding to the single track operation setting or the multitrack operation setting or each railroad equipment switching interlocking logic 11a corresponding to the railroad track switching unit. Since the storage addresses are set respectively in the above, and the storage addresses (starting addresses) of these railroad equipment switching interlocking logics 11a are stored in the look-up table on the same ROM, the railroad equipment control switching means 16 is required. The corresponding storage address (start address) is searched by referring to the lookup table, and the corresponding storage address (start address) found is referred to, and the railway equipment switching interlocking logic corresponding to single-track operation setting or multi-track operation setting is searched. 11a or read the data of railway equipment switching interlocking logic 11a corresponding to the railway track switching unit Succoth can.

That is, when the interlocking logic mode switching signal 15a is received, the railroad equipment switching interlocking logic 11a (corresponding to the input interlocking logical mode 12 (for example, the line of switching 1 in FIG. 1B)) That is, the railway equipment switching interlocking logic 11a) corresponding to the line of switching 1 is selected in the storage area of the interlocking logic storage means 11 (ROM) based on the storage address (starting address) on the lookup table, and the railway equipment The interlocking logic switching signal 16a can be generated to prompt switching of the railway line.

Only when the interlocking logical mode switching signal 15a is received, the interlocking logical switching signal 16a of the railroad equipment is generated to prompt the switching of the railway line, so that the switching of the railway line with high fail-safety and reliability can be performed. It can be realized in the electronic interlocking device 10.

When the railway equipment control switching means 16 receives the interlocking logical mode switching stop signal 15b, it can generate the interlocking logical switching stop signal 16b and prompt the stop of the railway line switching.

While the electronic interlocking device 10 comprehensively controls the entire railway equipment such as a station yard or a set unit,
According to the operation of the electronic interlocking device 10, the electronic railroad crossing control device 20 controls whether or not to close the railroad crossing.

For example, it is necessary to switch the setting between single-track operation and double-track operation for convenience of construction work, or to temporarily change the content or unit of the controlled object when the operation is obstructed or some need arises. In such a case, electronic interlocking device 1
0 switches the railroad device switching interlocking logics 11a, 11a ...

That is, the interlocking logic mode input means 13 switches the control target to a predetermined railroad equipment switching unit, and the railroad equipment switching interlocking logic 11a corresponding to each of the plurality of railroad equipment switching units in the interlocking logic storage means 11. , 1
1a ... are designated as railroad equipment switching interlocking logics 11a, 11a ... According to the switching of the target railroad equipment switching unit.

In response to this, the railway equipment control switching means 16
Selects the railway equipment switching interlocking logic 11a, 11a ... In the storage area of the interlocking logic storage means 11 to switch the railway equipment.

Next, the operation of the electronic railroad crossing control device 20 for controlling the railroad crossing under the control of the electronic interlocking device 10 will be described. In the electronic railroad crossing control device 20, the railroad device switching interlocking logic 11a, 11a, ... Stored in the railroad crossing control logic storage means 21 in accordance with the switching of the railroad device switching unit.
To the level crossing control logic 21a corresponding to.

That is, the electronic railroad crossing control device 20 obtains the information that the electronic interlocking device 10 has been switched, and the crossing control logic mode switching means 23 causes the electronic interlocking control stored in the railroad crossing control logic storage means 21. A plurality of railroad crossing control logics 21a corresponding to the interlocking logic storage means 11 of the device 10,
21a ... is a switched railroad equipment switching interlocking logic 11
Switching to the level crossing control logic 21a according to a, 11a ....
For safety, the switching signal by the railroad crossing control logic mode switching means 23 is issued only when the power is turned on.

Further, the link means 25 takes in route configuration information and train entry / exit information relating to the level crossing in the interlocking logic of the electronic interlocking device 10. Link means 25
Is an interface for information exchange between the electronic interlocking device 10 and the electronic railroad crossing control device 20, and, for example, a serial transmission system using an optical fiber is used. As the route configuration information and the train entry / exit information, for example, signal control information indicating whether or not an on-site route or a departure route is being set, rolling display information indicating on which side the train runs, where the train is It includes track circuit information indicating whether the user is present, and which way the direction determined by the signal control information is set, that is, route locking information indicating the direction in which the train runs.

Then, in order to ensure safety, the logic matching judging means 24 compares the matching between the interlocking logic mode of the electronic interlocking device 10 and its own leveling control logic 21a mode. The mode recognized by the electronic railroad crossing control device 20 itself is compared with the mode switched and set by the electronic interlocking device 10, and if they match, it is determined that there is consistency. If there is a match, the switching is approved and the level crossing control is continued.
Switch to the safe side, such as by constantly shutting off railroad crossings.

The electronic railroad crossing control device 20 is also the electronic interlocking device 10.
Similar to the above, information is repeatedly transmitted and received in a predetermined system cycle, and the security of information transmission is ensured by the agreement and disagreement of information. Then, the comparison of the mode information by the logical matching judging means 24 is performed at the beginning before the crossing control logic processing of this system cycle is started.

After the consistency is confirmed, the route configuration information and the train entry / exit information from the link means (25) or the railroad crossing information input means 26 is used to enter / exit the railroad crossing of the target section. Level crossing controller B, C,
After receiving the signal D, the railroad crossing is blocked or opened while ensuring the safety of the railroad crossing.

Explaining this with reference to FIG. 4, in the solid line route showing before the switching of the railroad crossing control logic, the railroad crossing sounds when the train enters the railroad crossing controller B in the down control. Then, when the departure course of the departure signal 6R or 7R is not set, the railroad crossing stops after a certain time after arriving at the arrival line 2RT or 9LT. When the departure signal of the departure signal 6R or 7R is set, the railroad crossing continues to ring. Next, when the departure signal of the departure signal 6R or 7R is set, the railroad crossing immediately starts ringing. In the uphill control, the train enters the crossing controller D and starts ringing,
The crossing controller C is advanced to stop ringing.

Then, when there is a level crossing control logic that operates as described above, this is changed to the route indicated by the broken line, and at the same time, the entire system is switched to the level crossing control logic corresponding to this switched route. This switching is performed as described above without manual intervention, and can be performed quickly and surely without requiring a test or the like.

As described above, the electronic railroad crossing control device switches the railroad crossing control logic 21a according to a preset procedure without requiring replacement of the storage means while following the switching by the electronic interlocking device 10. No mistakes are made and no human labor is required, and both cost reduction and safety assurance can be achieved.
