Abstract

PROBLEM TO BE SOLVED: To be advantageous in the aspect of a repair cost by proceeding with repair according to a repair registered order at the time of detecting a deteriorated state from monitoring data of deterioration index to smooth repair operation. SOLUTION: When a deterioration detecting part 3 detects the deteriorated state (b) from equipment efficiency (a), a repair register part 4 retrieves (c) the matrix table 5 between a deterioration index and an repair item to register (d) the pertinent repair item. A repair execution order setting part 6 sets registered repair items (e) in a priority processing order such as an order from being larger in efficiency deterioration. A display means 7 reports a repair item coming to an execution step (f) to an operator. An analytic function part 8 analyzes the deteriorated state (b) detected by the deterioration detection part 3 to release-judge (g) repair processing or to reset the priority processing order. Then a repair evaluation part 10 evaluates whether repair set by the repair execution order setting part 6 gives or not an effective repair effect to each facility by including a waiting time.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to management of operation and maintenance of facilities such as stations and buildings, and more particularly to an operation management apparatus for facility equipment capable of selectively executing repair items according to the deterioration state.

[0002]

2. Description of the Related Art Conventionally, with respect to equipment installed in facilities such as stations and buildings, it is often customary to decide whether to repair or regularly repair equipment whenever deterioration is detected. I couldn't raise it. If it is repaired each time, a decrease in operating efficiency can be avoided, but the operating rate will decrease. Regular repairs do not take into account changes in usage conditions, so repairs may be too early or too late.

Furthermore, while maintenance personnel have been reduced and maintenance costs have been reduced due to maintenance rationalization, it is virtually impossible to carry out repairs each time. In addition, even if a scheduled repair is planned, if there is no need for repair, it may be decided to defer it. From the above, if the management system is confused, it can not be used because it is not repaired when you want to use it,
Unnecessary and urgent construction work will occur.

[0004]

As described above, the conventional operation management system cannot be adapted to the current environment, and the input cannot be effectively achieved despite the large amount of input work. This becomes an obstacle, and it is difficult to realize effective life cycle cost management. Therefore, the purpose of the present invention is to provide a repair index based on the deterioration index,
It is to provide a mechanism for systematically moving the operation management of facilities.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to the invention according to claim 1, wherein in the operation and maintenance management of a facility equipped with equipment required for operation management, deterioration of the equipment is caused. Deterioration detection means for detecting a deterioration state based on an index, a deterioration index-repair item correspondence table that stores the deterioration state of the device and a repair item corresponding thereto,
According to this correspondence table, a repair registration unit for registering repair items corresponding to the deterioration state of the equipment, a repair execution order setting unit for setting the registered repair items in order of priority, and the repair items to be carried out. When the deterioration state is detected from the deterioration index monitoring data, the repair is performed in accordance with the repair registration order.

According to a second aspect of the present invention, in the facility equipment operation management apparatus according to the first aspect, the transition of the deterioration state of the equipment detected by the deterioration detection means is analyzed, and the order of repair items to be preferentially executed is determined. Equipped with an analysis function unit for reviewing and canceling registered repair items, the priority order will be raised when the deterioration state is increasing, and the registration will be canceled for items that have been repaired.

According to a third aspect of the present invention, in the facility equipment operation management apparatus according to the first aspect, there is provided a repair evaluation means for evaluating whether or not the deteriorated state of the equipment having a repair item to be restored has recovered after a predetermined time. , Comprehensive evaluation of the repair status, such as whether or not what must be carried out and whether the result was valid and valid are to be carried out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of an operation management system for facility equipment according to the present invention. As shown in FIG. 1, a boiler 11 and a refrigerator 1 are installed in a facility 1 of a station or a building.
2. It is composed of operation management target equipment (facility equipment) such as the water pump 13.

The operation management system 2 adds the basic configuration of the deterioration detection unit 3, the repair registration unit 4, the deterioration index vs. repair item matrix table 5, the repair execution order setting unit 6 and the display unit 7, and quantitative judgment. Case analysis function section 8, waiting time element 9 for observing repair effect, and repair evaluation section 10
Consists of

Next, the operation of this embodiment having such a configuration will be described. First, each operation management target device 11, 1
The device efficiency a of 2 and 13 is input to the deterioration detection unit 3. As another method, the input value and the output value of each device may be input separately, and the ratio of the output to the input may be taken in the deterioration detecting unit to be converted into the efficiency.

When the deterioration detecting unit 3 detects the deterioration state b from the equipment efficiency a, the repair registration unit 4 searches the deterioration index vs. repair item matrix table 5 to register the corresponding repair item d. The registered repair items e are set by the repair execution order setting unit 6 in the order in which priority processing should be performed, for example, in descending order of efficiency reduction. Repair items f at the implementation stage
Is notified to the operator by the display unit 7.

The analysis function unit 8 analyzes the deterioration state b detected by the deterioration detection unit 3 and performs an analysis function of judging whether the repair process is canceled g or changing the priority process order h. The repair evaluation part 10 evaluates whether or not the repair set by the repair implementation order setting part 6 has brought about an effective repair effect in each facility by including a waiting time (difference time between the commands i and j). Then, the result k is displayed.

The operation of the deterioration index vs. repair item matrix table 5 will be described based on the table shown in FIG. 2 when the target device is a boiler. In the vertical column in FIG. 2, the deterioration index is divided into less than 10% and 10% or more for efficiency reduction, and in the latter case, more serious repair is performed.
In the horizontal column, repair items are divided into three according to the operation period, and repair items are assigned according to the degree of progress of deterioration at each time. By doing so, the corresponding repair item can be registered.

Analysis function unit 8 when quantitative judgment is added
The effect of the above will be described based on the deterioration index transition diagram of FIG. In FIG. 3, the horizontal axis t is time, and the vertical axis b is the deteriorated state. The graphs p and q show the state where the deterioration determination threshold value r is exceeded. Since the graph p corresponds to the recovery from the deteriorated state due to the repair, in this case, the analysis function unit 8
Sends a repair determination cancellation command g to the repair registration unit 4,
Unregister. Since the graph q corresponds to the rapid progress of the deterioration state, in this case, the analysis function unit 8 sends the rearrangement command h of the priority processing order to the repair execution order setting unit 6 to raise the priority order.

In this way, it becomes possible to quantitatively judge both the deterioration amount and the rate of change over time, and more detailed repair measures can be taken. Next, the operation of the repair evaluation unit 10 when the judgment of the repair effect is added will be described based on the repair evaluation table of FIG. In FIG. 4, vertical columns indicate repair items for the target device, and horizontal columns indicate evaluation ranks. The deterioration index is not limited to the device efficiency, and may be the condensation pressure for a refrigerator and the discharge pressure for a water pump.
If the deterioration state recovers after the waiting time, the judgment is good,
If it does not recover, it gives a grace and suspends the judgment. Further, if the deterioration state is recovered after the lapse of twice the waiting time, the determination is possible, and if not, the determination is not possible.

In this way, after displaying the repair items, whether or not what must be carried out is carried out, whether it has been carried out even after the judgment pending state, and whether the result is valid and valid, etc. Can be evaluated.

[0017]

As described above, according to the first aspect of the present invention, when the deterioration state is detected from the deterioration index monitoring data, the repair work is carried out in accordance with the repair registration order, so that the repair work can be carried out smoothly. It will be carried out and it will be very advantageous in terms of repair cost.

According to the second aspect of the present invention, by providing an analysis function, a quantitative judgment can be made, and the threshold value for deterioration judgment can be changed according to the operating condition, or the change rate of deterioration can be changed. , It becomes possible to add device abnormality judgment that is not seen in normal operation.

According to the third aspect of the invention, by attaching the repair evaluation, it is possible to judge the quality of the content of the repair item and the appropriateness of the repair time, and it is possible to brush up or review the system function.
