DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an airfield light monitoring and control device for monitoring and controlling the luminous intensity and turning on / off of a large number of light devices disposed on a runway or approach path of an airfield, and controlling power supply to each light device. The present invention relates to a lighting power control device for an airport.

[0002]

2. Description of the Related Art An airfield light monitoring and control device for monitoring and controlling the luminous intensity and turning on / off of a large number of light devices disposed on a runway or approach road of an airfield is constructed, for example, as shown in FIG.

[0003] A plurality of lighting devices 1a, 1b are provided on both sides of the runway.
Are arranged. One lighting device 1a is a transmission terminal 2
a and 2b are connected to the main logical controller 3a and the backup logical controller 3b, respectively. The other lighting device 1b is connected to the main logic control unit 3a and the backup logic control unit 3b via transmission terminals 2c and 2d, respectively. The main logic control unit 3a and the backup logic control unit 3b have a power supply device such as CCR / CCT.
4 are connected. The lighting console 5 is connected to the main logic control unit 3a and the backup logic control unit 3b.

[0004] Lighting devices 1a and 1b and transmission terminals 2a to 2d are arranged on the runway side, and a lighting operation console 5, logic control units 3a and 3b and CCR / CCT4 are arranged in the control room and its vicinity. Have been.

In such a light monitoring and control device, the main logic control unit 3a and the backup logic control unit 3b have substantially the same configuration, and the luminous intensity and lighting of the light devices 1a and 1b are controlled in accordance with a preset control logic. Monitor / control off / off. In the normal state, the main logic control unit 3a
Monitors and controls the lighting devices 1a and 1b. Then, if an abnormality occurs in the main logic control unit 3a for some reason,
Instead of the main logic control unit 3a, a backup logic control unit 3b monitors and controls each lighting device 1a, 1b.

[0006] An air traffic controller resident in the control tower operates the lighting operation console 5 as necessary to operate the logical control unit 3a.
The lighting devices 1a and 1b are manually controlled via (3b). An airfield light power control device that monitors and controls the power supplied to a large number of light devices disposed on the runway or approach road of the airfield is configured as shown in FIG. 9, for example.

A plurality of lighting devices 1c, 1d are provided on both sides of the runway.
Are arranged. One lighting device 1c is a transmission terminal 2
e and 2f are connected to the main power controller 6a and the backup power controller 6b, respectively. The other lighting device 1e is connected to a main power control unit 6a and a backup power control unit 6b via transmission terminals 2g and 2h, respectively. A power facility 7 that supplies AC power to each of the lighting devices 1c and 1d is connected to the main power control unit 6a and the backup power control unit 6b. A power console 8 is connected to the main power controller 6a and the backup power controller 6b.

Lighting devices 1c and 1d and transmission terminals 2e to 2h are provided on the runway side, and a power console 8, power control units 6a and 6b, and power equipment are provided in a control room and its vicinity. ing.

In such a lighting power control device, the main power control unit 6a and the backup power control unit 6b monitor and control the power supplied from the power equipment 7 to each of the lighting devices 1c and 1e, and detect the power interruption. Or a function of preventing excessive power from being supplied.

In addition to the above-mentioned common functions, the main power control unit 6a has a predetermined contracted power integration amount within a certain period such as one month, for example. Each lighting device 1c, 1e so as not to exceed
And demand control for controlling the power supplied to the power supply.

In the normal state, the main power controller 6a monitors and controls the power supplied to each of the lighting devices 1c and 1d. Then, if an abnormality occurs in the main power control unit 6a due to any factor, the backup power control unit 6b replaces the main power control unit 6a with each of the lighting devices 1c,
The power supplied to 1d is monitored and controlled.

An air traffic controller resident in the control tower operates the power console 8 as necessary to operate the power control unit 6a.
The electric power supplied to each of the lighting devices 1c and 1d via (6b) is manually controlled.

[0013]

However, the above-described lamp monitoring control device and lamp power control device still have the following problems. That is, in the light monitoring and control device shown in FIG. 8, when an abnormality occurs in the main logic control unit 3a, the control for each of the light devices 1a and 1b is automatically switched to the backup logic control unit 3b.
Then, each lighting device 1 is controlled by the backup logic control unit 3b.
When the repair of the main logic control unit 3a is completed and the main logic control unit 3a is restored to the normal state during the control period of the a and 1b, the control of each of the lighting devices 1a and 1b is manually controlled in the lighting operation console 5 by the backup logic. It is necessary to return from the control unit 3b to the main logic control unit 3a.

The switching of the control in the manual operation is different from the automatic switching, and is instantaneous, but each of the lighting devices 1a and 1b is in the non-control state. Therefore, the reliability of the control in the light monitoring and control device is reduced.

Further, the work load on the controller who switches the lighting operation console 5 is increased. Also, the main logic control unit 3a
There is a concern that an operation error may be erroneously returned to the main logic control unit 3a erroneously, even though is not restored to the normal state.

Furthermore, the control logic for controlling the luminous intensity of each of the lighting devices 1a and 1b and the lighting / extinguishing may be different depending on the purpose of use of each of the lighting devices 1a and 1b, the installation location, and the like. In this case, when the logical control unit that controls each of the lighting devices 1a and 1b is changed, it is necessary to determine whether the control logic set in the logical control unit also needs to be changed, and to switch when necessary. There is.

However, in the above-described lamp monitoring and control device, the logic control unit is surely changed, but the control logic is manually switched when a controller needs it. Therefore, there is a concern that switching may not be performed properly due to a human error of the controller.

In the lamp power control device shown in FIG. 9, when an abnormality occurs in the main power control unit 6a, the backup power control unit 6 replaces the main power control unit 6a.
b monitors and controls the power supplied to each of the lighting devices 1c and 1d, but the backup power control unit 6b is in a pause state during the operation period of the main power control unit 6a. The demand control for controlling the power supplied to each of the lighting devices 1c and 1e so as not to exceed the contracted power integration amount that has been executed cannot be taken over and executed.

That is, once the control of the power supplied to each of the lighting devices 1c and 1e is switched to another power control unit, the demand control is stopped at that point and the demand control is continued within a certain period such as one month. There is a problem that control cannot be performed.

The present invention has been made in view of such circumstances, and an equivalent function is added to a plurality of logical control units for monitoring and controlling each lighting device, so that automatic switching is performed in any direction when an abnormality occurs. In addition, the control theory set in the logic control unit is automatically switched as necessary, minimizing manual operations by operators, preventing the occurrence of human error, and ensuring reliability as a monitoring control device. It is an object of the present invention to provide an airfield light monitoring and control device capable of further improving the above.

Further, even when the main power control unit is in a standby state, the power measurement value is transmitted to the backup power control unit at a fixed period, so that even if the main power control unit is in a standby state, each lighting device is controlled. It is an object of the present invention to provide an airfield lamp power control device capable of continuously performing demand control on supplied power and improving power control performance as a power control device without significantly increasing manufacturing costs.

[0022]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a lighting operation console installed on an airfield control tower, a lighting device arranged on a runway, and a lighting device for the lighting device. A pair of logical control units having a function of monitoring and controlling the state based on a predetermined control logic; usually, one of the pair of logical control units is an active system and the other is a standby system, and the operating system is abnormal. When the occurrence occurs, in the airfield light monitoring and control device that changes the standby system to the active system and changes the active system to the standby system,
The normal / abnormal status signal from each logical control unit designated as the operating system or the standby system and the selection signal for each logical control unit from the lighting console were input, and the status signal from the operating system changed abnormally. When the standby system and the active system are changed, a system switching device that changes between the standby system and the active system in response to the selection command for the standby system in a state where the abnormal state of the standby system is restored Provided.

In the airfield light monitoring and control device thus configured, when an abnormality occurs in the operating system, the standby system is automatically switched to the operating system, and the operating system is switched to the standby system.
Even if the abnormal state of the standby system is recovered, it does not return to the original state unless a selection command for the standby system is input. That is, useless switching of the system is suppressed as much as possible.

Further, even if an error occurs and a selection command is sent to the logical control unit, which is a standby system in which the error continues, the system is not switched, so that a malfunction due to a human error is prevented. It can be prevented before it happens.

Another invention relates to a lighting operation console installed in a control tower of an airfield, a lighting device installed on a runway,
A pair of logic control units having a function of monitoring and controlling the lighting state of the lighting device based on a predetermined control logic, and a plurality of transmission terminals interposed in a transmission path connecting the lighting device and the logic control unit; An airfield that normally has one of a pair of logical control units as an active system and the other as a standby system, and when an abnormality occurs in the active system, changes the standby system to the active system and changes the active system to the standby system. In the lighting monitoring control device of the above, each transmission terminal updates the cyclic data transmitted from the logical control unit to which it is connected at regular intervals and returns it to the logical control unit, and the received cyclic data is normal. At this time, the control information received from the logic control unit is transferred to the lighting device.

Each of the logic control units updates the cyclic data received from the transmission terminal to which it is connected and transmits the updated data to the transmission terminal after a lapse of a predetermined period. The self-side abnormality information is sent to the logic control unit.

In the airfield light monitoring and control apparatus thus configured, cyclic data is transmitted and received between the logic control unit and the transmission terminal at regular intervals. And
For example, the value of the tie-click data is updated each time it is transmitted. Therefore, if the cyclic data is not updated even though it is received, or if the cyclic data is not received for a certain period of time, it can be determined that some abnormality has occurred on the partner side.

Therefore, the transmission terminal discards information from the logical control unit determined to be abnormal without transferring it to the lighting device. Further, each logical control unit notifies the other party of the normal / abnormal state of its own side, thereby preventing the control from being switched to the logical control unit in the abnormal state, thereby improving the reliability of the device.

Another invention relates to a power console installed on a control tower of an airport, a lighting device installed on a runway,
A power facility for supplying power to the lighting device, a main power control unit and a backup power control unit having a function of monitoring and controlling a use state of power supplied from the power facility to the lighting device, and usually a main power control unit And a system switching device for changing the backup power control unit to the active system and changing the main power control unit to the standby system when an abnormality occurs in the main power control unit. In the lighting power control device for an airfield, the main power control unit, when it is an active system, controls the power supplied to the lighting device so that the integrated power amount supplied to the lighting device does not exceed a predetermined contracted power integration amount. If the self-standby system is used, the power supplied to the lighting device is sampled at regular intervals, and the sampled value is used as backup power. And transmits it to the control unit.

When the backup power control unit is an active system, the backup power control unit executes demand control for controlling the power supplied to the lighting device by using a sampling value received at regular intervals from the main power control unit.

In the airfield light power control device configured as described above, the main power control unit does not stop the operation and outputs power at a constant cycle even when the main power control unit is designated as the standby system. Sampling is performed and the sampled value is transmitted to the backup power control unit. Therefore, the backup power control unit can continue the demand control executed by the main power control unit using the sampling value.

Another aspect of the present invention is the above-described lamp power control device, wherein the main power control unit detects a reactive power value of power supplied to the lamp device when the main power control unit is an operating system.
Based on the reactive power value, the phase advance capacitor is turned on and off, and the backup power control unit uses the sampling value received at regular intervals from the main power control unit when the backup power control unit is an active system. The reactive power value of the power supplied to the power supply is detected, and based on the reactive power value, the closing / opening control of the phase advance capacitor is performed.

In the airfield lamp power control device configured as described above, in addition to the continuation of the demand control described above, the backup power control unit can also execute the reactive power control.

Still another invention relates to a lighting console installed in a control tower of an airfield, a plurality of lighting devices arranged on a runway, and a lighting state of each lighting device based on a predetermined control logic. A plurality of logical control units having a function of monitoring and controlling,
A logic control console for setting a control logic corresponding to the lighting device connected to each logic control unit for each logic control unit,
When a certain number of logical controllers are the active system and the other logical controllers are the standby systems, when one active system fails, one standby system is changed to the active system and an error occurs. In the airfield light monitoring and control device that changes the operating system of the lighting device to the standby system, the control logic corresponding to the lighting device is stored and retained for each lighting device, and a logic control unit that monitors and controls the lighting device is provided by another logic control unit. When the logic control unit is changed, the corresponding logic control unit is provided with a control logic management device for setting the control logic corresponding to the lighting device.

In the airfield light monitoring and control device configured as described above, even if the logical control unit for monitoring and controlling the light device is changed to another logical control unit, the control logic is automatically changed at the same time. Therefore, the work load on the controller can be reduced, and each lighting device can be prevented from being monitored and controlled by erroneous control logic.

The light monitoring and control device 11 and the light power control device 1 constituting the light control system thus configured

When some kind of abnormality in the logic control unit of the operating system in a factor occurs, in place of the logic control unit of the operating system, the lighting system logic controller of the standby system becomes operational system 22 ₁ through 22 _n Monitor and control.

An air traffic controller resident in the control tower operates the lighting operation console 24 as necessary, and operates the lighting devices 22 via one of the logical control units 14a (14b) designated as the operating system.
The _{1 ~22 n} to monitor control.

a and Sb are sent to the system switching device 15 via the respective logic controllers 14a and 14b.

The lighting console 26 is provided with each logical control unit 1.
The control logic is set for the logical control units 4a (14b), and various management tasks are performed for the logical control units 14a (14b). Wherein each transmission terminal _{20 1 ~20 n, 21 1 ~21} n

FIG. 2 shows each of the transmission terminals 20 _{1 to} 20 _n , 21 ₁
Through 21 _n is a flowchart showing the cyclic data exchange processing performed. The device itself takes in transmission data transmitted from a logic control unit connected via a signal line (S1), and the transmission data includes, for example, cyclic data consisting of sequentially increasing numbers and the like. Then, it is checked whether or not the value of the cyclic data has been updated normally by comparing with the value at the time when the cyclic data was fetched last time (S2). If it has been updated normally, the logical control unit determines that it is normal (S3). In this case, the control command included in the transmission data is fetched and transferred to the lighting terminal connected to itself (S
4).

Then, 1 is added (updated) to the number of the received cyclic data (S5), and the updated cyclic data is returned to the logic controller (S6). Also, S
If the cyclic data fetched in 2 has not been updated from the previous value, or if the cyclic data cannot be received after a certain period of time has passed (S7), the logic control unit determines that there is an abnormality. (S8). In this case, the control command contained in the transmission data is discarded without being taken in, and the process proceeds to S5, where 1 is added (updated) to the number of the received cyclic data (S5), and the updated cyclic data is added. The click data is returned to the logic control unit (S6).

FIG. 3 shows each of the logic control units 14a and 14b.
Is a flowchart showing a cyclic data transfer process performed by the server. The transmission data transmitted from the transmission terminal connected thereto is fetched (Q1), and the transmission data includes, for example, cyclic data consisting of sequentially increasing numbers and the like. It is checked whether or not the value is updated normally by comparing with the value at the time when the data was fetched last time (Q2). If the transmission terminal has been updated normally, it is determined that the transmission terminal is normal (Q3). In this case, the monitoring information included in the transmission data is fetched and a normal monitoring control process is executed (Q4).

Next, a normal signal of the transmission terminal is transmitted to the system switching device 15 (Q5). Then, 1 is added (updated) to the number of the received cyclic data (Q6), and after the elapse of the predetermined period, the updated cyclic data is transmitted to the transmission terminal (Q7).

If the cyclic data fetched in Q2 has not been updated from the previous value, or if the cyclic data cannot be received after a certain period of time (S8), the transmission terminal is abnormal. It is determined that there is (Q9).
Then, in this case, the monitoring information included in the transmission data is discarded without being taken in, the process proceeds to Q5, and an abnormal signal of the transmission terminal is transmitted to the system switching device 15. Thereafter, 1 is added (updated) to the number of the received cyclic data (Q6),
After the elapse of the certain period, the updated cyclic data is transmitted to the transmission terminal (S7).

[0056] Each logic control unit 14a, 14b and the respective transmission terminals _{20 1 ~20 n, 21 1 ~21} n , the self side operating system, the transfer process of the cyclic data were also above cases the standby Running. However, when designated as the standby system, actual transmission / reception of control information and monitoring information is not executed, and only transmission / reception of cyclic data is performed.

As described above, by performing transmission and reception of cyclic data, each of the logical control units 14a and 14b can detect whether the transmission terminal on its own side is normal or abnormal. Also,
Each of the logic control units 14a and 14b has a self-diagnosis function, and determines whether the logic control unit is normal or abnormal. Then, each of the logic control units 14a and 14b sends status signals Da and Db indicating whether the self side including the transmission terminal is normal or abnormal to the system switching device 15.

The system switching device 15 is composed of a plurality of logic circuit elements, for example, as shown in FIG. Light operation desk 24
The selection signal Sa for the first-system logic control unit 14a and the selection signal Sb for the second-system logic control unit 14b, which are input from the first and second gates, are respectively input to one ends of the AND gates 41a and 41b via one ends of the OR gates 40a and 40b. .

The state signals Da and Db input from the 1-system logic control unit 14a and the 2-system logic control unit 14b are directly input to the other ends of the AND gates 41a and 41b, respectively, and the inverters 32a and 42b And the logical value is inverted and input to the other ends of the OR gates 40a and 40b.

Then, the operation instruction signals Ea and Eb are sent from the AND gates 41a and 41b to the first-system logic controller 14a and the second-system logic controller 14b. When the high-level operation instruction signals Ea and Eb are input to the first-system logical control unit 14a and the second-system logical control unit 14b, respectively, the operation mode is changed from the standby system to the active system. However, when one operation mode is changed, the other operation mode is changed in the opposite direction in conjunction. That is, the same operation mode is not simultaneously set during the operation period.

FIG. 5 is a time chart showing the switching operation of the system switching device 15. When the power of the system is turned on and the first-system logical control unit 14a and the second-system logical control unit 14b rise normally, the state signals Da and Db go to the high level. When, for example, a selection signal Sa for designating the first-system logic control unit 14a is input from the lighting console 24, the AND gate 41
An operation instruction signal Ea is output from a. As a result, the first system logical control unit 14a becomes the active system, and the second system logical control unit 14a becomes active.
b becomes a standby system.

Then, the 1-system logical control unit 14 which is the operating system
When an abnormality occurs on the side a and the state signal Da changes to a low level, the operation instruction signal Eb is output from the AND gate 41a, and the second-system logic control unit 14b becomes the active system. As a result, the 1-system logic control unit 14a becomes the standby system.

However, even if the abnormal state of the 1-system logic control section 14a is recovered, the operation instruction signal Ea is not output from the AND gate 41a. In this state, when the selection signal Sa is input from the lighting operation console 24, the operation instruction signal Ea is output from the AND gate 41a for the first time, and the first-system logical control unit 14a changes to the active system, and the second-system logical control unit 1
4b changes to the standby system.

During the period in which the abnormal state of the 1-system logic control unit 14a has not been recovered, that is, during the period when the state signal Da is at a low level, even if the selection signal Sa is transmitted from the lamp operation console 24, the AND gate 41a Does not output the operation instruction signal Ea.

[0065] Thus, in this system switching device 15, when abnormal or generated in the operational system of the logic control unit 14a (14b), the logic control unit 14b of the monitoring control standby for each lighting apparatus 22 ₁ through 22 _n It is automatically changed to (14a).

Then, even if the standby logic control unit 14a
Even if the abnormal state of (14b) is recovered, the lighting operation console 24 for the corresponding logical controller 14a (14b) of the standby system is restored.
Unless the selection command Sa is input from the CPU, it does not return to the original state. That is, useless control switching between the first-system logical control unit 14a and the second-system logical control unit 14b is suppressed as much as possible.

Further, even if a selection command Sa is sent to the logical control unit 14a (14b) which is a standby system in which an abnormality has occurred and the abnormality is continuing, the system is not switched.
It is possible to prevent the occurrence of a malfunction caused by a human error of the controller.

As described above, when the system switching is required, it can be automatically performed without error, so that the operation burden on the controller can be reduced, the probability of occurrence of human error can be reduced, and the reliability of the entire light monitoring and control device can be reduced. Performance can be greatly improved.
