It has and.

Next, the outline of the operation of the operator will be described.
Since the operator constantly operates the facility monitoring and control device 24 hours in the driving monitoring room for 24 hours, a plurality of operators form a team, and a plurality of teams work alternately.

The operation monitoring work is not only for monitoring the operation status of the equipment 11 of the facility, but also for various operations such as ON / OFF of the equipment 11, setting of control parameters for automatic operation, environmental management of the facility, maintenance management of the equipment 11. Is required. Therefore, in addition to the operation monitoring control inside the operation monitoring room, work outside the operation monitoring room such as on-site patrol is also performed. There are various kinds of equipment 11 to be handled, and it is necessary to acquire specialized knowledge and accumulated experience as well as handling know-how.

In order to cover both these qualitative and quantitative aspects, the operators form a team of a plurality of people and operate them on a shift basis in terms of time. The operator's experience and knowledge differ depending on each operator, and the operation monitoring operation that can be shared is also determined accordingly.

Therefore, in the present invention, an operation mode is provided to define the operation pattern that can be operated by each operator. That is, the operation mode that can be operated by the A operator is the A exclusive operation mode, the B operator is the B exclusive operation mode, and when the operator cannot be specified, for example, the unattended operation mode when the operator is unattended.

Correspondence between the operation mode and the operation pattern is defined in advance, and the operation is restricted for each operator. FIG.
FIG. 4 shows a flow chart of the operation mode setting means 14 of the embodiment of the present invention, FIG. 4 shows an operation mode / operation pattern correspondence table 40 of the embodiment of the present invention, and FIG. 5 shows an operation pattern definition table 50 of the embodiment of the present invention. The setting of the operation mode by the operation mode setting means 14 will be described with reference to these.

First, a case will be described in which an operator is replaced as a transition to the most general operating state. In order for the operator to operate each console 12 with the responsibility of operation, when the operator carries out a driving operation, a procedure operation of operator change is performed.

Using the CRT screen of the input / output operation unit 12, the operator recognition means 13 selects from the registered operator list. If the selected operator requests the password and confirms that he / she is the person himself, and if he / she recognizes that he / she is the operator, he / she accepts the change of the operator, and stores the operation mode dedicated to the operator by the operation mode setting means 14 as shown in step 30. It is set in the current operation mode storage unit 41 of the unit 24.

The current operation mode storage unit 41 holds an operation mode name for indicating the responsibility of the operation of the input / output operation unit 12. Operation mode /
The operation pattern definition table 50 indicated by the operation pattern number shown in the operation pattern correspondence table 40 corresponding to the operation mode name defines the contents that can be operated. As shown in step 31, from the operation pattern definition table 50, the contents that can be operated are the current operation pattern storage unit 51.
Set and held.

When the operator finishes his / her duties or leaves the operation monitoring room, operator recognition means
Step 13 detects that the end button has been pressed and
As shown in 32 and step 33, the unmanned operation mode is set in the current operation mode storage unit 41 by the operation mode setting means 14, and the corresponding operation pattern is set in the current operation pattern storage unit 51.

While the unmanned operation mode is set, even if an erroneous operation is performed by an outsider, it becomes invalid except for the display operation as described later, and the influence can be eliminated.

The driving environment recognition means 16 can recognize two states. First, there is recognition of the operator's non-operation state, that is, recognition of the state of the operating environment when the operator is absent or the like and does not operate anything for a preset time.

The operating environment recognizing means 16 is a preset time interval between the input / output operation of the operator, that is, the operation of the operator from the input / output operation section 12 and the next input / output operation. When this is exceeded, this is detected.

That is, when the operator does not perform a predetermined procedure at the end of his / her duties or when he / she leaves the office, or when an abnormality occurs in the operator and he / she cannot carry out regular duties, this is detected and the responsible operator is absent. Assuming that there is, as shown in step 32 and step 33, the operation mode setting means 14 sets the unmanned operation mode in the current operation mode storage unit 41, and correspondingly sets the display operation pattern in the current operation pattern storage unit 51. .

Next, there is a case where the sensor function of the equipment operation management device 10 operates to recognize an emergency state such as a fire or a power failure.
The driving environment recognition means 16 is a facility monitoring control device 10 which is a center of system operation and various equipment 11 of the facility which is a monitored device.
It is possible to detect this in the event of an emergency in the environment, such as a fire or a power failure, and to detect a part of the monitoring and control equipment of the equipment 11 of the facility, such as a disaster prevention panel or a sensor installed in the power receiving and transforming facility. Detect by signal.

When the emergency state is detected, the operation mode setting means 14 sets the emergency operation mode in the current operation mode storage section 41 as shown in steps 34 and 35, and all operations required for the emergency state are possible. The standard operation pattern is set in the current operation pattern storage unit 51 as an operation pattern corresponding to the operation pattern, that is, the operation restriction is released.

In the emergency operation mode, all operations necessary for the driving operation in an emergency can be performed, and any operator who rushes regardless of the operator can deal with the emergency state.

In the case of fire detection, the operator can operate a measure for minimizing damage such as stopping introduction of external air by air conditioning depending on the situation while displaying a fire confirmation screen.

FIG. 6 shows an operation monitoring regulation means of the embodiment of the present invention.
15 shows a flow chart of FIG. 7, FIG. 7 shows a flow chart of the operation recording means 18 of the embodiment of the present invention, and FIG. 8 shows an operation record print example 80 of the embodiment of the present invention. The operation monitoring regulation means 15 and the operation recording means 18 will be described with reference to these.

As shown in FIG. 6, the operation monitoring regulation means 15 confirms that the operation is performed by an operator who is qualified to operate, and thereby regulates other non-regulated operations.
When the operator uses the CRT screen on the input / output operation unit 12 to perform a driving operation of the driven equipment group 11 with a keyboard, a mouse, or buttons or switches of the operation panel 25, the operation monitoring regulation means 15 is used. Monitor the operation contents.

In step 60, when the state is simply displayed during the driving operation, the operation can be performed regardless of the operator. The current operation pattern storage unit 51 stores the content of executable operations permitted to the operator who is currently responsible for driving, and confirms it by comparing it with the type of operation to be executed in step 61. To do.

The operation recording means 18 activated in step 62 records the operation contents in time, the operation mode name (becomes the operator name or the special mode name) in the data storage section 24, and the printer 28 of the input / output operation section 12 Is also printed and recorded sequentially. An example 80 of the printed contents is shown in FIG.

As for the permitted operation and display operation, the function of each driving operation is activated as shown in step 63. If the operation is not permitted, it is invalidated in step 64 and the invalid operation display flag in the data storage unit 24 is turned on. In addition to the display indicating that the invalid operation is also invalid, the operation recording means is activated in step 65 to record the operation.

As shown in FIG. 7, in step 70, the operation recording restricting means 15 records the data in the operation storing means 18 so that the invalid operation is also invalid.
It is determined whether the invalid operation display flag stored in 24 is ON or OFF, and valid operation recording and invalid operation recording are performed in step 71 and step 72, respectively.

The operation record is stored in the data storage unit for later analysis.
The data is electronically recorded in 24 and is printed on the printer 28 of the input / output operation unit 12 so that the operation history can be immediately confirmed. An operation record print example 80 in FIG. 8 will be described. It is recorded from the point where the operator E performs the operator change procedure to start working in the operation monitoring room at 13:10.

14:00 E The operator performed the operation for the device number 1. This is the operation mode / operation pattern correspondence table 40 of FIG. 4 and the operation pattern definition table 50 of FIG.
Since the operation contents with the operation qualification determined from the above are stored as the current operation pattern, it is recorded that the operation has been executed as an effective operation by comparing and confirming.

At 15:10, the operation monitoring regulation means 15 is attempting to set the control parameters for the device number 1.
The operation is rejected as an invalid operation which is not permitted as the E operator, and it is recorded that the operator tried to perform the invalid operation.

At 20:00, it can be seen that the D operator is being replaced. At 22:30, the operation mode is the emergency operation mode, which means that the operating environment recognition means 16 has detected an abnormality such as a fire and has been set to the emergency operation mode.
The minute means that the device 5 was operated in the emergency operation mode.

The device 5 is not normally qualified to be operated by the operator D, but in an emergency, the device 5 which is a special device must handle the operation as a minimum measure.
For example, in normal operation, the air conditioner draws in outside air and introduces it into the room after adjustment, but when a fire is detected, it is necessary to take emergency measures such as turning off the power to the air conditioner so that smoke is not introduced into the room. In the emergency operation mode, it can be operated by any operator. [Other Embodiments] (a) In an operation monitoring room having a plurality of operator consoles 12, naturally, a plurality of operators are involved in the operator's operation at the same time, and it is necessary to be aware of how the operations are monitored and recorded in correspondence with the numbers on the operator console 12. However, implementation by setting the current operation mode and the current operation pattern by the number of consoles 12 can be realized by expansion of this embodiment.

(B) When a large number of operators replace each other and perform an alternate operation, it is necessary to simplify the operation for changing operators. In this case, a wireless IC or the like worn by the operators is used. It is also easy to install the ID card recognition device on the operation console 12 so that the operator can be automatically identified each time the operation is performed without the operator actually being aware.

[0053]

As is apparent from the above description, according to the present invention, by the operator recognition means 13, the operation mode setting means 14, the operation monitoring regulation means 15, the driving environment recognition means 16 and the operation recording means 18, for example, The following improvements can be achieved.

The operation can be restricted so that an inexperienced operator cannot perform an important driving operation, and the operation mistake of the device can be prevented. -Even when the operating operators are divided according to the type of device, even unfamiliar devices other than those in charge cannot be operated, and operation mistakes can be prevented.

When an accident occurs or a complaint occurs due to some operation mistake, it becomes clear which operator's operation is performed, clarification of the responsibility of the operation of the system, investigation of the cause, and determination of the device. We can make improvements.

In the case where the operator room is unattended, there is no fear that it will interfere with driving even if an outsider intrudes and is operated by himself. -Emergency measures can be automatically performed even when an emergency occurs in the system environment such as power outage or fire, and active disaster prevention can be achieved.

In this way, it is possible to clarify the responsibility of system operation, prevent accidents, and take positive measures when an accident occurs, and there is a remarkable industrial effect that the safety of system operation can be improved.
